Definitions

  • the present invention relates to a suction device for the, in particular pneumatic, conveyance of suction goods such as feed, litter or manure from an animal stall with the aid of oppression. Furthermore, the invention relates to an associated method, a use of the device and a suction arrangement for removing suction material from an animal stall.
  • the barn floor is usually covered with litter such as long straw, chopped straw, shavings or sawdust to bind the manure and urine of the animals.
  • litter such as long straw, chopped straw, shavings or sawdust to bind the manure and urine of the animals.
  • Regular cleaning of dung, dirty and damp bedding is important for the health and well-being of the animals.
  • the boxes must be cleared every day, sometimes several times a day.
  • the manure and soiled litter are removed by hand, the manure being picked up with a manure fork or shovel and, for example, being transported from the barn for further disposal using a wheelbarrow.
  • the amount of manure to be moved is considerable and can only be managed with a lot of staff and time.
  • pneumatic conveying systems for stable manure are also known, in which the material is transported via a suction pipe running in the stable building with the aid of a suction conveyor blower (transport fan) connected to it.
  • the manure can be sucked into the suction pipe via a suction opening and conveyed in the direction of the suction conveyor blower.
  • This conveys the material to the material separator, which is arranged behind the suction conveyor fan along the transport path from the suction opening in the direction of the material separator, i.e. not on the negative pressure side of the fan but on the positive pressure side. Since the material separator is located behind the suction conveyor fan, the extracted material passes through the suction conveyor fan and is finally separated with overpressure.
  • the problem with this is that the technical requirements for pneumatic conveying and the selection of the right conveying method depend in principle very much on the material being conveyed.
  • the material to be conveyed can have a wide variety of properties with regard to quantity, shape, size, density, moisture and / or frictional resistance and place high demands on the suction power of the blower.
  • the suction conveyance of wet and cohesive or “baking” material such as horse manure can, in conventional conveyor systems, lead to a loss of transport capacity and blockage of the line, especially in areas of curvature.
  • An attempt is usually made to counter these problems by using high negative pressures and large diameters and radii of curvature of the transport lines.
  • a suction device for suction material from an animal stall is specified.
  • An animal stable in the sense of the present invention can be, for example, a horse stable, a cattle stable, a pig stable or a poultry house. It is preferably a horse stable.
  • the suction material can comprise, for example, feed, bedding such as long straw, chopped straw, planes or sawdust or manure, in particular horse manure, and combinations thereof.
  • the suction device has a suction line in the negative pressure mode, which can be acted upon with a negative pressure by means of a suction device that can be connected or connected to the suction line, such as a negative pressure fan or a suction fan.
  • the suction line has an inlet air opening which is designed to use the vacuum to enter the inlet line, preferably continuously, into the suction line and to provide this air flow flowing through at least in sections.
  • the suction line has a suction material opening or insertion opening, which is arranged and preferably designed with respect to a longitudinal axis of the suction line running in the direction of the air flow and / or along the air flow direction behind the supply air opening, that is to say downstream in the air flow direction is to enter the suction material in the already existing air flow.
  • the inventor has recognized that, in particular, moist and cohesive suction material, in particular using a transport fan, is the cause of the known problems of the pneumatic conveying of animal stall waste.
  • horse manure tends to form stable plugs in pneumatic conveying, especially in high conveying concentrations and at low conveying speeds.
  • these plugs can reduce the cross-section of the transport line and drastically reduce the speed of the downstream air flow or completely close the transport line. The remaining flow speed is then usually no longer sufficient to transport further goods over longer distances through the transport line, and further blockages can occur.
  • the present invention solves this problem by the special construction of the suction line with the separate supply air and insertion opening.
  • the supply air opening ensures a continuous intake of supply air to prevent blockages, such as during the process of inserting material.
  • the insertion opening arranged downstream of the supply air opening as seen in the air flow direction, the suction material is introduced into an already existing air flow, preferably seen laterally or from the radial direction with respect to the longitudinal axis of the suction line or the air flow direction.
  • the suction material is less compacted or compressed from the outset, through which the vacuum entrains the suction material.
  • the suction line can also have two or more supply air openings and / or two or more insertion openings.
  • the suction device can have two or more suction lines, in particular in With respect to the air flow flowing through the suction lines or with respect to the suction device connection, it can be connected in series and / or parallel to one another. In this way, two or more suction lines can be operated by means of a single suction device, for example a transport fan.
  • the suction line can also comprise or consist of a suction line or a plurality of suction lines, wherein “suction line” in each case denotes a section of the suction line, each with a supply air and insertion opening as described above.
  • suction line in each case denotes a section of the suction line, each with a supply air and insertion opening as described above.
  • suction lines are preferably connected in series or in parallel to one another.
  • at least one such suction line is expediently assigned to each animal box and / or pen in the barn.
  • the insertion opening is set up to introduce the suction material into the suction line in a direction which is at least partially opposite to the longitudinal axis of the suction line running in the direction of the air flow or the air flow direction.
  • the suction material is preferably not inserted directly into the opening, but rather via a filler neck or opening arranged at the opening and opening into the suction line and which is set up to supply the suction material to the opening.
  • This has the advantage that a certain independence from the throw-in quantity or the volume of the suction material can be achieved, since the throw-in nozzle mechanically limits the supply of the suction material into the suction line.
  • Another advantage is that in this way the registered suction material and the air flow in the suction line meet at different flow directions and / or flow velocities, and the suction material is thereby introduced and mixed particularly effectively and uniformly into the air flow or into the suction line.
  • the throw-in nozzle on the suction line is at an angle of greater than or equal to 90 °, greater than or equal to 100 °, greater than or equal to 110 ° with respect to the longitudinal axis of the suction line running in the direction of the air flow , greater than or equal to 120 ° or greater than or equal to 130 °, in particular at an angle of approximately or exactly 135 °.
  • the angle is formed by the longitudinal central axis of the suction line and the longitudinal central axis of the insertion nozzle.
  • gravity can also be used to accelerate the suction material.
  • the suction material hits the air flow opposite to the direction of the suction material, which picks up the suction material and conveys it away from the opening.
  • the throw-in nozzle on the suction line is preferably at an angle of less than 180 °, less than or equal to 170 °, less than or equal to 160 °, less than or equal to 150 ° or less or in relation to the longitudinal axis of the suction line running in the direction of the air flow arranged equal to 140 °.
  • the insertion nozzle on the suction line is particularly preferred at an angle of 110 ° to 160 °, from 120 ° to 150 ° or from 130 ° to 140 °, in particular from the longitudinal axis of the suction line running in the direction of the air flow 133 ° to 137 °.
  • the inventor has achieved particularly effective mixing and acceleration of the suction material when it enters the air flow.
  • the throw-in nozzle has a constriction, via which the suction material can be fed to the throw-in opening.
  • the constriction is preferably designed as a cone, which tapers in the direction of the insertion opening.
  • the conical shape causes the suction material to slide down and / or prevents the suction material from sticking to the constriction.
  • the suction material is accelerated as it passes through the constriction and shear forces arise when it passes through, which, particularly in the case of compact suction material, can promote fragmentation and uniform mixing into the air flow.
  • the constriction can be designed, for example, as a funnel element, which is preferably arranged concentrically in the insertion nozzle. Throw-in nozzle and funnel element can be formed together as a one-piece or two-piece component.
  • the filler neck and the funnel element are two separate components, so that the funnel element can be replaced.
  • the constriction in the insertion nozzle can be easily adapted to the quantity and properties of the suction material by changing between funnel elements with different diameters.
  • the suction line has a shut-off device that can be opened and closed again, such as, for example, a shut-off valve, which is the inlet air opening or the insertion opening is connected downstream in relation to the longitudinal axis of the suction line running in the direction of the air flow and which at least partially prevents or blocks the entry of the air flow through the supply air opening in the closed state or interrupts the air flow when closing.
  • a shut-off valve which is the inlet air opening or the insertion opening is connected downstream in relation to the longitudinal axis of the suction line running in the direction of the air flow and which at least partially prevents or blocks the entry of the air flow through the supply air opening in the closed state or interrupts the air flow when closing.
  • the suction line can be closed when not in use and thus "switched off".
  • the suction device comprises several suction lines connected in series or in parallel, since switching off suction lines that are not required reduces the power requirement of the suction device and increases the efficiency of the “active” suction lines that are in operation.
  • each suction line comprises or consists of a plurality of suction lines, each of which has a supply air opening and an insertion opening
  • each suction line is preferably equipped with its own shut-off device.
  • each suction point can be closed or opened separately.
  • the suction strands are assigned to different stable areas, for example different animal boxes or animal pens, that is to say preferably suction material is also to be applied to them at different times.
  • the suction line for the respective barn area can be put into operation (air flow flows through the supply air opening and the extraction line) and out of operation (no air flow sufficient for the transport of suction material flows through the supply air opening and the extraction line). This improves the suction effect of the suction line currently in operation and ensures the most efficient use of the performance of the suction device.
  • the insertion opening is preferably arranged in a section of the suction line which can be rotated, for example by means of a rotary tube, about an axis of rotation of the suction line running parallel to the direction of the air flow. Accordingly, a first area of the suction line with the section can be rotated relative to a second area of the suction line, which is preferably arranged downstream of the first section.
  • This has the advantage that the suction line covers a larger working area by turning the opening accordingly and can be easily loaded with the suction material from different positions. For example, it is possible to conveniently process two or more adjacent stall boxes via the same suction line by rotating them accordingly.
  • the insertion opening is preferably rotatable by at least 45 °, at least 90 °, at least 135 °, at least 180 °, at least 225 °, at least 270 °, at least 315 °, particularly preferably by at least 360 ° or even larger angles, and in particular freely rotatably arranged on the suction line.
  • This makes it possible to vacuum several animal boxes with a single suction line, especially if the stall design ensures the possibility of immediately adjacent boxes.
  • the suction line can be arranged in the animal stall at least partially in the floor area or at least partially above the floor, for example above animal boxes or pens.
  • the suction line can be guided at least partially under the roof of the animal house. Any combination of these arrangements is also possible.
  • a first section of the suction line in the form of a suction line runs at least partially vertically to the floor of the animal house, hereinafter also referred to as a “riser”. It is possible, for example, that such a suction line is arranged in several animal boxes or bays of an animal house, which leads as a riser into the suction line.
  • each suction line or riser preferably contains at least the supply air opening and the insertion opening and optionally also the rotary tube.
  • an end of the first partial area or of the suction line / riser that faces the floor can have the supply air opening or be designed as a supply air opening.
  • the end facing the floor can open out above the floor of the animal house and in this way form the supply air opening.
  • This axial arrangement of the supply air opening with respect to the longitudinal axis of the first section or the suction line / riser extending in the direction of the air flow is advantageous because it ensures a high efficiency of the negative pressure at the supply air opening and at the same time leads to a lower negative pressure effect at the insertion opening. This achieves a high flow velocity of the air flow in the suction line, which, in combination with the vacuum-reduced entry of the suction material through the insertion opening, causes the suction material to be mixed particularly effectively into the air flow.
  • the suction device is further arranged and / or set up such that the air flow is at least partially blocked before entering the supply air opening and / or at least partially deflected and / or accelerated when entering the supply air opening.
  • Both the congestion of the air flow and the deflection have the effect that the air flow accelerates strongly as it enters the supply line through the intake air opening and suction material that is introduced through the insertion opening is entrained by the air flow.
  • the individual or, in particular, cumulative effect of both effects enables an air flow velocity to be achieved which even allows the registered suction material to be conveyed through vertical partial regions of the suction line, such as the above-mentioned riser, against gravity.
  • the supply air opening in particular the end of the first section or the suction line / riser, which is designed as a supply air opening and faces the floor, is arranged such that the air flow is stowed and / or accelerated in the floor area of the animal house before it enters the supply air opening.
  • the supply air opening is preferably arranged at least obliquely or essentially parallel to the floor.
  • the supply air opening is arranged at a distance of at most 70 mm, at most 60 mm, at most 50 mm or at most 40 mm above the floor of the animal house.
  • the supply air opening is preferably arranged at least 10 mm, at least 20 mm, at least 30 mm or at least 40 mm above the floor of the animal house.
  • the supply air opening is particularly preferably arranged 30 mm to 50 mm or 35 mm to 45 mm above the floor of the animal house.
  • this arrangement has the effect that ambient air flowing essentially horizontally across the floor is supplied to the supply air opening, which air is only at least partially deflected, for example vertically, in the inlet region of the supply air opening and is thereby additionally accelerated. In this way, very high air flow velocities can be achieved when the air flow enters through the supply air opening.
  • a flow resistance element in front of the supply air opening at the distances mentioned above in relation to the floor in order to achieve the same effects.
  • the flow resistance element can, for example, be partially or essentially plate-shaped and is preferably arranged obliquely or essentially parallel to the supply air opening.
  • the flow resistance element is preferably at least partially circular, the flow resistance element and the longitudinal center axis of the suction line or of the suction line or of the riser being arranged in particular concentrically.

  • the flow resistance element can be connected to the suction line or the suction line or the riser, for example, via one or more holding elements.
  • the flow resistance element is, however, not restricted to the aforementioned configurations. Rather, those skilled in the art are without in the light of the present disclosure Further alternative configurations can be seen in order to achieve the same effects according to the invention.
  • the inside diameter and / or the inside cross section of the suction line can be constant, in particular in the suction line and / or in other sections.
  • the inside diameter and / or the inside cross section between the supply air opening and the insertion opening is preferably constant.
  • the inner cross section of the suction line can be circular.
  • the first partial area or the suction line or the riser preferably opens into a second partial area of the suction line, which runs at least partially horizontally above the floor of the animal house, for example as a secondary line above the animal boxes or below the animal stall ceiling. Via the second section, the suction material can be conveyed out of the box area, for example, for further disposal in another barn area or to outside the animal barn.
  • At least one end of the second partial area preferably has a cover that can be opened and closed again. This is particularly preferably the end of the second partial region located upstream in the air flow direction.
  • the cover which is generally more susceptible to blockages, is more easily accessible for maintenance and cleaning work. In particular, the cover can be used for gentle cleaning of the suction line in a simple manner using compressed air or a broom, whereas conventional line systems generally require more complex cleaning by rinsing with water with an additional risk of corrosion.

  • the suction line preferably has a discharge opening which is set up to feed the suction material from the suction line to the separating device.
  • the separating device or the material separator can be designed to separate the suction material (in the case of centrifugal or cyclone separators, for example by means of centrifugal and / or gravity) from the air flow and, for example, to separate them at a charging station.

  • the suction device is located behind the separating device or the material separator in the suction device according to the invention, so that, in contrast to the prior art, the material is separated in the vacuum mode.
  • the suction line or the insertion nozzle are preferably tubular and / or tubular and can each independently or both, for example, have an inner diameter of at least 10 cm, at least 12 cm, at least 15 cm or at least 18 cm.
  • the suction line or the insertion nozzle can each have a diameter of at most 30 cm, at most 25 cm or at most 20 cm, independently of one another or both.
