Definitions

  • the invention relates to a device for closing and continuously emptying the container of a processing machine by means of a closure lid arranged in the container bottom, which is driven in and out by a lifting device on a bearing outside the container into the emptying opening in the container bottom.
  • processing machines e.g. Mixing machines with a stationary or rotating mixing container and with continuous discharge of the mix.
  • the mixing container is emptied via a cylindrical or rotating funnel which widens downwards in the shape of a truncated cone and is attached to the emptying opening.
  • a conveyor e.g. a belt conveyor, vibration conveyor, scratch conveyor.
  • the inlet of this conveyor is designed so that the mix is dammed up between the discharge funnel and the conveyor inlet and that the backflow is effective right into the mixer.
  • the object of the invention is therefore to provide a closing device of the type described at the outset, with which both rough and fine regulation of the discharge during operation and closure of the container are possible without high investment costs and with robust operating behavior.
  • the closure cover has a controllable rotary drive
  • the lifting device is coupled to a control drive for the exact adjustment of the position of the bearing
  • the emptying opening has an outlet funnel which widens outward in the shape of a truncated cone and into which the closure cover can be immersed .
  • the quick adjustment is achieved through the precise and quick adjustment of the storage position, e.g. the position of a bearing arm, by means of the control drive mentioned, whereby a rough adjustment of the discharge rate is possible, so to speak.
  • the opening width of the discharge or emptying opening in the container bottom is set. This enables quick and very precise e.g. the adaptation to the respective grain size and the flow behavior of the processed mix.
  • the fine adjustment is achieved via the adjustable rotary drive of the closure cap around the axis of rotation running perpendicular to the closure cap. This is coaxial with the drive shaft, which protrudes from a geared motor towards the cover.
  • the coupling between the sealing cover and the drive shaft takes place in the most convenient manner for the machine specialist, e.g. via tongue and groove connection.
  • the fine control is thus carried out by the adjustable rotary drive of the closure cover, which e.g. can be controlled depending on the drive line of the processing machine.
  • closure cover Due to the possibility of immersing the closure lid in the conically widening discharge funnel, A gentle flow of material is guaranteed, and the closure cover can also be retracted against the flowing material flow during operation, at the end of the processing process or to adjust the discharge quantity.
  • the closure cover is provided with wing attachments on its upper side facing the emptying opening.
  • Their shape can be different, e.g. radial, curved arrangements of blade-like blades are expedient, a wide and low, depending on the task, narrower and / or tall embodiment of the blades can be beneficial.
  • the outer contour of the wing-like attachments is preferably to be adapted to the outlet funnel which widens conically downwards.
  • the wing attachments according to the invention can accommodate the drive device, in particular the rotary shaft in the center of the plate of the closure cover.
  • the control drive for the adjustment of the bearing arm can be designed electrically, pneumatically, hydraulically, but the position adjustment of the closure cover can also be changed manually using a handwheel. It is advisable if a display device is provided on the adjusting device such that the position of the bearing arm of the operator can be seen immediately regardless of the type of actuator.
  • a freewheel and / or an elastic bearing is installed between the control drive and the closure cover.
  • the closing device according to the invention can be used for both stationary and rotating containers in processing machines.
  • the freewheel is particularly favorable when it is a compulsory mixer with a rotating container.
  • the closure lid can also move into the rotating container or its emptying opening and is carried along by it at the beginning of the closure state.
  • the adjustment of the movement of the closing plate on the one hand and of the container bottom on the other hand can take place via the correspondingly provided regulation of the control drive, so that the drive of the closing lid is stopped in the closed position.
  • the lifting device can be a swivel shaft which is connected to a bearing arm so that the controllable rotary drive allows the inclination of the bearing arm to be adjusted precisely
  • the closure lid can be adjustable according to the invention in the direction perpendicular to the bottom of the container.
  • This vertical movement component can be introduced through a hydraulic cylinder which is expediently attached to a stationary outlet pipe. With the piston rod of this hydraulic cylinder, a hydraulic motor is expediently attached via flanges, the output shaft of which carries the sealing cover.
  • the sealing cover has a seal on its outer circumference has even a liquid-tight closure of the closure lid in the emptying opening of the container bottom is possible.
  • sealing cover is heated, then hot mixtures and / or sticky preparation materials can also be processed with advantage.
  • the speed control is provided electrically, hydraulically or mechanically.
  • the cover speed can be controlled electrically by means of a direct current motor, hydraulically by an adjustable hydraulic motor or mechanically by an adjustable gear. It is also expedient if the speed control is provided depending on the load on the power consumption of the drive motor or motors of the processing machine.
  • the rotating discharge funnel and / or the sealing cover with a stationary scraper.
  • the closure cover it is preferred if it does not have the wing attachments mentioned above or the like but has a smooth surface.
  • the sealing cover can only be inserted into the outlet funnel to such an extent that a gap remains which corresponds to the thickness of the wiper or wipers. The opening cannot therefore be completely closed. However, this is generally not harmful in the case of sticky mix which only requires the use of scrapers.
  • the new closing device enables better operation for closing and continuously discharging processing materials at any time.
  • the discharge device can also be operated by an automatic control in such a way that when the desired discharge quantity is not reached and / or when the upper and lower speed limit of the rotary drive for the closure cover automatically adjusts the width of the emptying opening, for example by pivoting the bearing arm.
  • the closure cover itself is generally designated 6. In this embodiment, it consists of a circular plate 7, on the outer circumference 8 of which a sealing ring is arranged, but which is not shown in the drawings. In the middle of the circular plate 7 there is a bushing 9, which is fastened to the circular plate 7 and creates the connection with the drive shaft 11 via the spring 10 via the not shown groove. Wing-like attachments 12 are attached to the outside of the sleeve 9 and on top of the circular plate 7. In the case of the embodiments shown in the figures, this is only radially rectilinear thin plates in the form of blades, which are combined above via a hub part 13 to form a star-shaped discharge aid.
  • the drive shaft 11 is located on the output side of a transmission 14, on the drive side of which the electric motor 15 is flanged. This is carried via the gear 14 by the bearing arm 16, which is fastened to the pivot shaft 17, which is held on a frame 19, shown schematically, via a bearing generally denoted by 18.
  • the swivel drive also has a swivel lever 20 which is rigidly connected to the swivel shaft 17 and, in the illustration in FIG. 1, is moved via the control drive designed as an electric adjusting device 21.
  • control drive in the embodiment of FIG. 2 is a spindle 23 which is driven by a handwheel 22 and which, in the manner shown in FIG. 2, pivots the pivoting lever 20.
  • a pointer 24 is also attached to the pivot shaft 17, which allows the exact angle of inclination of the bearing arm 16 to be determined at any time via a scale 25.
  • the closure device is operated in such a way that, in the case of the embodiment in FIG. 1, the closure lid 6 is pivoted downward out of the emptying opening 2. Shortly after leaving the closed position, the circular plate 7 is still almost in the same plane as the container bottom 1, as shown in dash-dot lines in both embodiments in FIGS. 1 and 2.
  • the coarse adjustment is possible due to the different inclinations of the bearing arm 16, and the above explanations make it easy to imagine how a rotation of the circular plate 7, i.e. of the cover 6, a fine control of the discharge flow of the processed material allows.
  • the wing-like attachments 12 scoop the processed material by rotating the sealing cap 7 around the shaft 11 practically to a tapping point, not shown, so that the discharge flow does not come from the tapping point or the conveyor system arranged there but from the speed of the motor 15 and the position of the bearing arm 16 depends.
  • the closure cover 6 is mounted on the expelling end of the drive shaft 11 of the hydraulic motor 14 '.
  • the hydraulic motor 14 ' is connected to the piston rod 30 of a hydraulic cylinder 21' via flanges 31.
  • This hydraulic cylinder 21 ' is attached to a stationary outlet pipe 32 via two support rods 29.
  • the brackets can also be used to lead the supply lines 27 of the hydraulic motor 14 'and 28 for the hydraulic cylinder 21' to the outside.
  • Both the hydraulic system for the lifting movement and that for the rotary drive of the cover contain the corresponding accessories, such as pumps, valves, flow regulators, etc., outside the device shown.
  • FIGS. 1 to 3 naturally also contain all monitoring and signaling devices for the transmission of the lid speed and lid position into a corresponding control device.
