Definitions

  • the invention relates to a silo according to the preamble of claim 1.
  • Silos of the aforementioned type are filled using a blowing process. Before or after filling, these silos are placed on lifting vehicles by lifting vehicles and transported to the consumer of the material. These silos are unloaded on site using the hoists of the transport vehicles and set up vertically. In the known silos, the outlet is in the middle of the bottom of the vertical silo within the stand frame.
  • the known silos have the disadvantage that the filling should only be carried out with a fine-grained material using a blowing process. If coarse-grained, hard material is blown into these silos, there is an extremely high level of wear in the blowing system and silo, which leads to inefficient operation. Filling by means of a blowing process also requires a long service life.
  • the arrangement of the outlet in the middle of the silo floor within the stand frame requires additional conveying devices on site, which convey the material emerging from the silo out of the area of the stand frame and enter it into downstream systems or transport devices.
  • the invention has for its object to design silos of the type mentioned so that an optimal transport of flowable solids can be carried out.
  • the invention provides several, optionally combinable options for solving the transport problem of flowable solids in silos.
  • a filling opening with a closure is formed in a side wall section of the silo, so that the silo can be filled in the lying state by means of a loading or conveying device. Blow systems that tend to wear are not necessary in this case. The service life is reduced and this training solves part of a uniform transport problem.
  • the other part of this uniform transport problem is solved in that the bottom of the silo runs obliquely to the silo axis to an outlet arranged outside the stand frame. Is on site no additional conveyor is required at the consumer.
  • the material transported by the silo can be entered directly into downstream systems or conveyors.
  • the closure of the filling opening is advantageously designed as a flap closure.
  • This closure is sealed in a manner known per se. Because of the weight of the closure, it can be actuated by means of a working cylinder.
  • the cross section of the silo section lying above the floor has the shape of a rectangle, one side of which is replaced by an arc, in particular a circular arc section.
  • the arrangement of the filling opening in this circular arc section brings with it a substantial advantage when loading the silo.
  • the silo constructed as described above has the shape of a parallelepiped box, which is closed off by means of a vault. When filling the container, for example with a wheel loader, it is in a lying position. The vaulted section of the silo is on top.
  • the flowable or pourable material entered forms a pouring cone in the final phase of the loading, the shape of which is optimally approximated by the vaulted section of the silo, so that "stuffing" of the filled material is not necessary.
  • the bottom of the silo extends downward in the direction of the curved, in particular circular cylindrical side wall section. It follows from this that the height of the silo is greater in the area of the curved or circular-cylindrical side wall section than in the area of the rectangular cross-sectional section. On the other hand, the volume fraction between two levels in the curved section of the silo is smaller than in the rectangular section.
  • two parallel rails extend along the side wall section of the silo opposite the full opening and have sections extending over the upper end wall of the silo. between which a receiving hook is arranged.
  • a blowing line opening into the interior of the silo is formed in at least one support of the stand frame.
  • the bottom of the silo runs obliquely to the silo axis to an outlet arranged outside the stand frame.
  • blow system into the stand frame leads to a compact construction.
  • Standardized connection devices can be provided at the filling location, so that the blowing in terms of apparatus expenditure is considerably simplified and thus improved.
  • a vent is advantageously formed in the area of the upper end wall of the silo. If a very light material is blown into the silo, the material can be blown from below through layers above. The mouth of the blow line is then arranged in the lower area of the standing silo.
  • a ventilation line is arranged in the silo, the mouth of which lies in the area of the upper end wall.
  • the ventilation line extends into a water box arranged on the floor frame.
  • the water box serves as a dust filter.
  • a perforated plate inserts a reduction in the size of the air bubbles, so that the dust particles are bonded much better to the water.
  • a section of the ventilation line is formed in a support of the stand frame.
  • the opening of the vent line is particularly advantageously arranged in the region of the wall section of the silo, which lies at the top in the lying state of the container.
  • the blow line extends into the area of the upper end wall. At least two orifices spaced apart from one another are provided on the blow line.
  • a vent valve for example a pressure relief valve or a flap, is arranged in the region of the upper end wall.
  • the silo according to the invention which can be filled by means of a blowing system, has, with the exception of the filling opening and the closure, the same structural features which were described in the first-mentioned embodiment and which bring the same advantages.
  • the silos are advantageously equipped according to the invention with a combination of the loading systems described above.
  • a silo has both a filling opening with a closure and at least one of the blow lines described above.
  • Such silos are suitable for transporting a wide range of substances or materials, so that the silo park can be kept small.
  • the silo In order to be able to use the silo as a separator for the transport of certain materials, there are in the upper end wall and / or in the side wall of the silo Two lockable suction line connections are arranged at a distance from each other.
  • the suction line connections are arranged in the side wall in the apex line of the curved side wall section of the silo.
  • the silo can be used as a separator, standing and / or lying, if one suction line connection is connected to the suction point via a suction connection line and the other to the suction side of a blower.
  • a shut-off valve is advantageously installed in the ventilation line in order to prevent false air from being sucked in when operating as a separator.
  • the silo is particularly advantageously designed to be resistant to overpressure and / or negative pressure.
  • the vacuum-resistant training is particularly useful when used as a separator.
  • Conveyors that convey the material to the processing site by means of compressed air are designed so that the material to be conveyed is removed from the silo in batches and stored in a pressure-tight storage container. After closing the storage container, the material is mechanically introduced into the air flow of a delivery line. The material flow on construction sites is sufficient for cleaning purposes. This material flow is too low for other uses. This procedure is particularly unsuitable for coarse material.
  • a T-shaped connecting piece can advantageously be connected to the outlet of the silo.
  • An air flow is passed through this T-shaped connector. This air flow pulls the material out of the silo.
  • Compressed air can advantageously be introduced into the silo via the blow line.
  • An expansion flap is provided to prevent damage to the silo.
  • the silo 1 shown in FIGS. 1 and 2 has a stand frame 2.
  • the carriers 4 of this stand frame 2 extend in a manner known per se from a floor frame 3 upwards.
  • the silo 1 has a bottom 11 which runs obliquely from top to bottom to the longitudinal axis of the silo.
  • This floor 11 extends at an angle to the longitudinal axis of the silo from a side wall of the silo 1 to an outlet 12 which, as shown, is arranged outside the stand frame 2. Due to its arrangement, this outlet 12 is directly accessible from the outside, so that downstream systems or corresponding conveyors can be connected directly to this outlet 12.
  • two parallel rails 6 extend upwards from the base frame 3. These rails 6 are extended beyond the upper end wall 17 of the silo 1 and a pivotable receiving eye 7 is mounted between these sections 6a. Its fulcrum lies in the silo axis of gravity of the standing silo. When setting up, the rail 6 can thus detach itself from the vehicle frame in the upper area and the silo tilts into the vertical position. In the lying transport position on the vehicle, the eyelet folds away and assumes the outer center position prescribed by the DIN regulation for hook deposit devices.
  • a tube or a roller bearing is provided in the section of the base frame 3 opposite the outlet 12.
  • FIG. 3 shows the cross section 16 of the silo section 15 lying above the floor 11.
  • This cross section 16 has the shape of a rectangle, one side of which is replaced by an arc. In the illustrated embodiment, this arc is a circular arc section.
  • the silo 1 has the shape of a parallelepiped box, which is closed off by a vault that lies when lying Silo is on top.
  • the side wall section 8 is a curved, in particular circular cylindrical side wall section.
  • the filling opening 9 is formed in this side wall section. The filling opening 9 is aligned with the outlet 12.
  • FIGS. 1 and 2 The embodiment described above and shown in FIGS. 1 and 2 is used for the transport of a coarse-grained hard material, such as sand or gravel.

  • the silo 1 is then equipped with a blowing system. Two embodiments of this blowing system are shown in Figures 1 and 2.
  • a blow line 18 is formed in the carrier 4 of the stand frame 2.
  • This blow line 18 has a blow line connection 26.
  • the blow line 18 opens into the silo 1 at 20 above the base 11.
  • This deep-lying mouth 20 leads to an operation in which the material is blown through the material layer that is formed in the silo 1 when it is blown in.
  • a vent line 22 is provided for venting, the mouth 23 of which lies in the region of the upper end wall 17 of the silo 1.
  • the vent line 22 extends downward out of the silo 1 and opens into a water tank 24, which serves as a dust filter.
  • the section of the vent line 22 extending out of the silo 1 can also be in one of the supports 4 of the stand frame 2 be trained.
  • a blow line 25 is formed, which has a connection 26.
  • the blow line 25 extends, as shown, into the silo 1 up to the area of the upper end wall 17.
  • the blow line has a plurality of orifices 27 which are spaced one above the other.
  • an overpressure or expansion valve 28 is provided for ventilation in the region of the upper end wall 17.
  • the two loading systems as shown in FIGS. 1 and 2, can be combined with one another.
  • devices to be described are also provided, which of course can also be installed in the embodiment shown in FIG. 2.
  • suction line connections 30 and 31 are arranged at a distance from one another in the upper end wall 17 of the silo 1.
  • suction line connections 32 and 33 can only be arranged at an axial distance from one another in the side wall of the silo 1, or can be provided together with the suction line connections 30 and 31 in the upper front wall 17. These suction line connections can be blocked.
  • a suction line can be connected to the suction line connection 30 that can be led to a point where material is to be extracted.
  • the suction line connection 31 is connected to a suction line which leads to a blower which is arranged, for example, in a vehicle.
