Description

The proposed useful relates to the pneumatic transportation of bulk materials through pipes, relates to the design of a sluice pump, which can be used to move fine-grained or granular materials, for example, grain, chemical granules, biofuel in the form of pellets.

The closest in technical essence and the achieved technical result to the proposed utility model is a sluice pump, protected by patent RU 136031 U, class. B65G 53/04, B65G 53/28, publ. 12/27/2013, adopted for the closest analogue (prototype).

The lock pump according to the prototype comprises a housing in which a cylindrical rotor is installed with cells located circumferentially relative to the rotor axis, filters installed in the rotor cells, a vacuum pump, a material loading hole, an air pumping hole, a compressed air supply opening, an opening for material unloading, made in the housing, rotor rotation drive.

When loading material, each cell of the rotor is aligned simultaneously with the hole for pumping air and with the hole for loading material, while turning the rotor to unload material, each cell of the rotor is aligned simultaneously with the hole for supplying compressed air and with the hole for unloading material.

The advantages and common features with the proposed utility model is that the lock pump according to the prototype can independently pick up (suck in) the material being transported and transport it to a distance.

However, unloading of material under the action of compressed air leads to the movement of air from the point of intake of the material to the point of unloading of the material, which is not always acceptable, according to fire or hygiene rules. For example, when pumping biofuels in the form of pellets, a large amount of dust flies along with pellets, which in itself is bad from the point of view of hygiene and fire hazard. In addition, the fire protection system of many solid fuel boilers is based on sealing the receiving hopper, which makes it impossible to use a pneumatic feed system.

The objective of the proposed utility model is the improvement of the design of the lock pump.

The technical result from the use of a utility model is to increase the safety and reliability of the device.

The problem is achieved in that in a sluice pump containing a housing in which a cylindrical rotor is installed with cells located circumferentially relative to the axis of the rotor, a hole for loading material, a hole for pumping air, a hole for unloading material, made in the housing, a filter installed in the hole for pumping air, a vacuum pump, a rotor rotation drive, the device further comprises a channel for venting air connected to the hole for pumping air on one side and with a vacuum Sos On the other hand, and a hole for discharging the air formed for a vacuum pump outside the enclosure; The vacuum pump is located outside the device.

In FIG. 1 is a vertical sectional view of a sluice pump.

In FIG. 2 shows a horizontal section through a sluice pump.

In FIG. 3 shows a vertical section of a sluice pump (option) with a vacuum pump located outside the device.

Structurally, the sluice pump in FIG. 1-3 contains:

1 - housing;

2 - rotor;

3 - cells;

4 - filter;

5 - rotor rotation drive;

6 - vacuum pump;

7 - hole for loading material;

8 - hole for pumping air;

9 - channel for air exhaust;

10 - hole for unloading material

11 - hole for air outlet.

A cylindrical rotor 2 is installed in the housing 1 with cells 3 arranged in a circle around the axis of the rotor 2, and a vacuum pump 6.

In the housing 1 there is a hole for loading material 7, a hole for pumping air 8, a channel for venting air 9, an opening for unloading material 10.

The filter 4 is installed in the hole for pumping air 8.

The channel for exhaust air 9 is connected to the hole for pumping air 8 on the one hand, and with a vacuum pump 6 on the other hand.

The hole for air outlet 11 is made behind the vacuum pump 6, outside the housing 1.

The vacuum pump 6 may be located outside the housing 1.

The proposed utility model works as follows.

The rotor 2 with cells 3 is rotated by a drive 5 mounted on the housing 1. Air movement is provided by a vacuum pump 6 installed, for example, in the housing 1, or outside the housing 1. When the rotor 2 is rotated, each cell 3 is alternately connected to the material loading hole 7 and with an opening for pumping air 8. The vacuum pump 6 draws in material with air, which through the hole for loading material 7 enters the cell 3 of the rotor 2. Air passes through a filter 4, installed in the hole for pumping air 8, through the opening for opening air samples 8, through the channel for exhausting air 9, through the vacuum pump 6 and through the hole for air outlet 11 is thrown to the point of intake. The material is deposited on the filter 4. With a further rotation of the rotor 2, each cell 3 filled with material is connected to the hole for unloading the material 10. In this case, the material from the cell 3 enters through the hole for unloading the material 10 into the product receiver under the action of gravity. At the same time, when the rotor 2 is rotated, the top edge of the cell 3 cleans the surface of the filter 4, which prevents its clogging. Filling with material of one cell 3 of rotor 2, connected to the hole for loading material 7 and with an opening for pumping air 8, is carried out simultaneously with the unloading of material from another cell 3 of the rotor 2 connected to the hole for unloading material.

The presence of a channel for exhausting air 9, connected to the hole for pumping air 8 on the one hand and to the vacuum pump 6 on the other hand, and the hole for outputting air 11, made behind the vacuum pump 6, outside the housing 1 of the device, eliminates the movement of air from the point material intake to the material discharge point, thereby increasing the safety and reliability of the device.
