Description

The invention relates to devices for handling bulk material iB capacity, in particular in hermetic volume, of various technological devices used in various sectors of the chemical, ceramic, construction and other industries.

A device for transferring bulk material into a hermetic volume is known, which contains a hopper with an outlet nozzle in the lower part, equipped with locking elements interconnected by a pull G 1J.

The disadvantage of this device is the limited scope due to the fact that when the air supply to the internal cavity of the elastic locking element is in it, even with a slight increase in its diameter, due to the connection of the locking elements i The lower shut-off element is / / valve / for the corresponding value. This creates a situation where the upper locking element due to i

insufficient increase in volume. I have not had time to close the connection section, and the lower valve is already open.

As a result, the air enters

5 into the cavity of the apparatus or the same technological environment comes out. Both of these are completely unacceptable in some production conditions. A device for overloading is known.

10 bulk material in a tank containing a hopper with an outlet nozzle, in the discharge channel of which an infinite bending is placed with an actuator with flexible shut-off

15 elements 2 J.

The disadvantage of this device is that the diameter of the locking elements is less than the internal diameter of the channels connecting the cavity

20 containers and body cavity. As a result, the air in the tank, together with bulk materials, enters the technologically apparatus below the choke, and the process gas first goes into the cavity

3

containers, and from there, when it is filled with raw material, into the environment. Both in the chemical as well as in other industries are completely prohibited.

The purpose of the invention is to ensure the leaktightness of the loaded container.

 For this, the outer size of the elastic locking elements is larger than the inner diameter of the discharge channel, and the length of the discharge channel is larger than the pitch of the location of the elastic stop

elements on the flexible tape, and the channel is provided with a nozzle connected to the gas suction system, installed at a distance from the beginning and end of the channel, the more elastic locking elements are located above the channel: the elements on the flexible pipe.

FIG. -1 shows the general view of the Ustfoystvo in the section; in fig. 2 - section A-A of FIG. one.

The device contains a bunker 1 with an outlet nozzle 2 passing 3 l 4 into cannulas, in the second there are branches of th 5 with elastic locking elements 6 fixed on it. T 5 ha are filled with flexible infinite and connected to two turning stars 7 and 8, one of which / 7 / is located in the lower part of the bunker, and the other in a hermetic volume of 9, in particular, the technological apparatus. : Asterisk 8 is leading. If necessary, both asterisks can be leading.

The device has fittings 10 connecting the channels 3 and 4 with the suction system. 10 Supply filters 1 1.

The device works as follows.

At. As the sprocket 8 turns counterclockwise, the elastic elements 6 located in the canapes 3 move downwards. At the same time, the bulk material 1IL from the bunker: falls into the gaps between elements 6 and, transported together with them, rises into volume 9. The communication of the latter with the atmosphere or the volume of the bunker is excluded, since channels 3 and 4 are permanently shut off elements that completely cross their cross section.

In order to prevent even the amount of air that KoiTopoe contains in the bulk material in

the gap between its particles, as well as when it is necessary to completely exclude product outflow (for example, gaseous) from the pressurized volume to the outside — channels 3 and 4 through nozzles 10 communicate with the pumping system. As a result of this, atmospheric air, transport, together with free-flowing meteriap in the gap between two elements 6.1, after the first of them has passed fitting 10, is removed through pipe 11 into the pumping system. The same happens with the gaseous process medium located between the 4 elements rising up through the channel 6. The device has a high production; This leads to the fact that, due to the inaccuracy of the action, it can be tens and hundreds of times larger than the known devices of similar purpose. Moreover, its performance is amenable to accurate control; The speed of rotation of the stars. Since the formation of vaults in the channel injected into this device is completely not affected. its capacity, since the material is between moving shut-off elements, it is impossible to block the channel here, i.e. the device is more reliable in operation. The exclusion of atmospheric air from entering the hermetic volume or from the technological product IB of the apparatus into the environment significantly expands the area of use of the device. It can be used to transfer various materials and bodies to the vacuum volume as well.

This device is applicable as for

loading of bulk materials into the hermetic volume, and for unloading from it.

The advantage of the device is also greater dosing accuracy of the material.

Since the need for locking devices in many industrial braces is great, replacing 1-in-place locking devices with those offered can provide great savings, amounting to tens of thousands of rubles.
