WITH

The invention relates to devices for packaging bulk materials into bags, in particular, products of microbiological synthesis. It can be used in the microbiological, food and chemical industries. A device for packaging loose materials is known, which contains a loading hopper, a pipe with a system for supplying compressed air, and a filling nozzle located in the lower part of the hopper 1. However, during operation, the dustiness of the air is great, because the material spills through the cumulative nozzle. download, and after it. The closest to the invention is a device for packaging bulk materials, comprising a hopper, a feed nozzle located at the outlet thereof, a device for forcibly feeding the bulk material and an aspiration system 2 fixed to the bottom of the hopper. the material in the container part of the material remains in the pipe and after removing the container empties out. In addition, a large amount of dust generated inside the container during loading, enters the surrounding atmosphere. The aim of the invention is to reduce the dustiness of the air by eliminating material spilling from the inlet nozzle, reducing dustiness and getting more complete suction of dust from the container. The unallocated goal is achieved by the device for mashing bulk materials, which contains a bunker, a charging nozzle located at the outlet of it, a device for forcing the bulk material and an aspiration system, fixed in the lower part of the hopper, is equipped with an additional nozzle that can be rotated about the horizontal axis and is located coaxially with the loading nozzle to form a gap with it, the outlet sections of the nozzles are conical and fixed at the end x walls, overlapping in the inoperative position of the loading pipe. In addition, the device is provided with a U-shaped perforated container box associated with an aspiration system. And also in the additional nozzle there is a half-ring cut-out. FIG. 1 shows the proposed device, a longitudinal section; in fig. 2 is a section A-A in FIG. one; in fig. 3 - section 1 7 filling nozzle with a closed outlet; in fig. 4 - aspiration box with filling fitting. The device for packaging loose materials consists of a hopper 1, an air duct 2 with an inlet 3 and an intermediate 4 valves for supplying compressed air to the device mounted in the lower part of the hopper of the loading nozzle 5 with a damper 6 and a device 7 with a valve 8 for forcing the material into the fitting. An additional pipe 9 is mounted on the device, which is located coaxial to the loading pipe 5 with the formation of a gap 10 connected with the suction system with the latter. The output sections of the pipes 5 and 9 are conical. Walls 11 are reinforced on the end ends of these sections. An additional nipple 9 and. Can rotate about a horizontal axis about 180 ° about the horizontal axis. This rotation is carried out using an air cylinder 12 interlocked with a button on the Start-Stop Device. In the non-operating position, the walls 11 are arranged so that they overlap the loading port. A semicircular cut-out 13 is made in the additional nozzle. In the working area of the device, an aspiration box 14 is mounted, having a perforation along the entire inner surface. The box has a conclusion. 15 from the filling nozzle, the output 16 from the vertical zone of suction and the output 17 from the lower zone of suction. All leads are connected to a common aspiration system. The U-shaped design of the box provides the most complete removal of product dust when filling and removing the bag. The device works as follows. The valve bag is put on the loading nozzle 5. The start button is turned on and simultaneously the valve 3 of the air duct 2 interlocked with it is turned on and compressed air is fed through the normally open valves 4 and 8 into the hopper 1 and the forced-feed device 7. At the same time, the cylinder 12 is turned on, which rotates the additional pipe 9 by an angle close to 180 °. In this case, the walls 11 on the two pipes are combined with the product under the action of m. Compressed air and the fluidizer devices 7 and through the open hole of the pipe enters the bag. The material supply is regulated by valves 4 and 8. Exhaust air through a semi-circular cut-out 13 and channel 10 is sucked out of the bag through terminal 15 of the box 14. After the bag is filled with material, the device is turned off, the valve 6 and valve 3 are closed, and the additional pipe 9 is turned by pneumatic cylinder 12, turning This wall 11 becomes one against the other (Fig. 3) and the outlet of the nozzle closes. The bag is removed and part of the product, spilled through the valve of the bag, is removed through the suction box 14.

The conical part of the fitting facilitates dressing of the bag and improves the aerodynamics of the product flow.

The proposed device eliminates the spillage of the material and reduces dust, which ultimately increases the reliability of the device.
