SU794226A1 - Pneumatic filling-up machine - Google Patents

Description

The pneumatic stacking machine consists of a metering drum 2 encased in casing 1 with 3 cells evenly spaced around the circumference and parallel to the axis of rotation. On the end walls of the drum, the upper 4 and lower 5 fixed end discs are fixed. The upper disc 4 is mounted for movement with the dispensing drum 2 in the axial direction.

The disk 4 is pressed against the drum 2 by means of hydraulic jacks 6. In the upper flap of the casing 1 there is an air inlet 7, a feed hopper 8, an exhaust nipple 9 and an air inlet pipe 10. To the bottom cover of the casing 1 are connected the exhaust pipe 11 and the transport pipe 12. Upper the disk 4 is made with a groove 13 communicated on the one hand with the air supply nozzles 7, and on the other hand with the cells 3 of the metering drum, which are in a loaded state during the operation of the machine with a filling material subject to dehydration.

The lower disk 5 is made with a groove 14 which is provided with a partition 15 with openings 16 made in the form of radially inclined channels. The groove 14 of the lower disk 5 communicates, on the one hand, with the cells 3 in the loaded state during operation and, on the other, with the exhaust pipe 11. If necessary, the exhaust pipe 11 can be connected via a non-return valve 17 to the air supply pipe 10 for cleaning the holes 16. To increase the intensity of the dewatering of the filling material, the charging funnel 8 is shifted towards the air supply pipe 10, which increases the time that the compressed air acts on the filling material to be dehydrated IAL. The filling machine is driven by a drive 18.

The pneumatic folding machine is operated in the following order.

The loading wet filling material through the feed funnel 8 sequentially fills the cells 3 of the metering drum 2 rotated by the machine drive 18. The upper disc 4 is pressed by the hydraulic jacks 6 to the metering drum, providing a seal between the rubbing parts of the machine. Moving around the circumference, the cells 3 with the loaded material communicate with the groove 13, which in turn communicates with the compressed air supplying pipe 7, whereby the compressed air enters the cells and blows free moisture out of them, which through the channels 16, are made inclined to reducing their clogging, together with the air, is removed through the exhaust pipe 11 connected to the exhaust device, for example, a vacuum pump. Dehydrated

the filling material is then blown out of the cells using an air supply pipe 10 into the transport pipe 12 and transported to the place of installation. The advantage of the described dewatering process is that, together with the intensive process of separating the liquid phase from the solid, fine grains of material are removed from the lower part of the cells of the metering drum, which ensures purity of the small particles of the contacting surfaces of the lower disc 5 and the metering drum, which ultimately invoice determines the effective

working capacity of the filling machine with fine-grained wet material.

In this case, a small percentage of the removal of thin classes from the cells of the metering drum of the machine during the dewatering process, for example, filling material from salt waste, occurs, since the clay, tracked under the action of compression of compressed air, creates an impermeable layer that prevents the removal of small particles of salt waste and the clay particles themselves from the upper layers of the cells.

The use of a pneumatic folding machine will improve the operational characteristics of the elements

pneumozakladochnogo complex (a source of compressed air and the transport pipeline), to reduce pickling in the developed space, which will significantly reduce the cost of soldering, improve the climatic parameters of mine air.
