Abstract

This invention relates to a technique for the dedusting of processes for the processing of bulk materials. The purpose of the invention is to increase the efficiency of dust collection and reduce the volume of aspirated air by reducing air leaks inside the shelter. For this, the cover of the housing has walls 1 and 2, the latter is fixed on the walls 3 and 4 of the shelter and the loading chute 8 with the formation of an outer duct. On the wall 2, an aspiration funnel 9 is installed between the dust precipitator 10 and the loading chute 8 and is communicated with the inter-shell space. Air with part of the dust passes through the dust precipitator 10, on which dust particles are deposited, and then enters the inlet of the funnel 9. It passes through the last purified air into the suction network. Air flow from the inner duct to the outer one during the operation of the shelter is impossible, because sealing along the shelter between the ducts is provided by a layer of Cbiny4ero material. 2 Il.

The invention relates to a technique for the dedusting of processes for the non-processing of bulk materials and can be used in the building materials industry, mining, metallurgical, coal and other sectors of the national economy, where industrial emissions occur.

The purpose of the invention is to increase the efficiency of dust collection and to reduce the volume of aspirated air by reducing air leaks inside the shelter.

FIG. 1 shows the aspiration coating, general view; in fig. 2 shows section A-A in FIG. one.

The aspiration shelter consists of a body formed by the main 1 and additional 2 walls of the lid with the formation of an inter-shell space between them, side 3, front 4 and rear 5 walls, elastic seals 6 at the interface between the shelter walls and the conveyor belt, apron 7 attached to the front wall-20 ke 4, loading chute 8, aspiration funnel 9 installed on the additional wall 2 of the lid directly at the loading chute, dust collector 10, the extrusion in the inner box is marked with the sign © and pressure ( vacuum) in the outer box - familiar). The vacuum in the outer duct is created by the ventilation fan, whose capacity must be equal to La. Air flow from the inner duct to the outer one during the operation of the shelter is impossible, since the sealing along the shelter between the outer and inner ducts is provided by a layer of material 11.

Aspiration shelter works as follows.

The material from the supply conveyor (not shown) along the charging chute 8 together with the ejected air enters the housing of the shelter formed by the main 1 and additional 2 walls of the cover, side 3, front 4 and rear 5 of the walls of the shelter; air with dust particles passes through dust precipitator 10, on which dust particles are deposited, then the dust-gas stream, reflecting from the front 4 and the additional 2 walls of the lid, is additionally released from dust particles and then enters the aspiration inlet 15

filled in the form of chains suspended from the sprig of 9 (dust particles fall out on the mating wall of the cover of the cover so that the shaving moving along the conveyor and

they are removed from the shelter), then the cleaned air through the crown 9 goes into the ascent so that the lower ends of the chain beads touch the surface of the bulk material 11 moving along the conveyor belt. Additional wall 2 of the shelter covers (represents, for example, a smooth sheet of metal) it is fixed on the outer side walls 3, the front 4 shelter walls and the loading chute 8, together with them forming an outer duct. The main wall of the lid is fixed on the inner side 3 walls

pyratic network. 30 Formula of Invention Aspiration Shelter of the place of transshipment of bulk material according to ed. St. No. 1257230 is characterized in that, in order to increase the efficiency of dedusting and lowering the loading chute 8, it will form with it an internal volume of aspirated air due to Replaceable box (fastenings can be made flange, by welding, etc.). The side walls 3 of the inner duct are attached to the side walls 3 of the outer air intake of the outside cover, the cover of the case is provided with an additional wall fixed on the walls of the shelter and the loading chute to form Robe, for example, kerchiefs. Internal., Outer box, while aspirated the box is intended for transportation of bulk material along the pipe and could eject air (-); the pressure in it is always higher than in the outer box (in the drawing The funnel is mounted on an additional wall between the dust precipitator and the loading chute and communicates with the inter-shell space. the pressure in the inner box is indicated by the sign © and the pressure (vacuum) in the outer box is familiar). The vacuum in the outer duct is created by the automation fan, whose capacity must be equal to La. Air flow from the inner duct to the outer one during the operation of the shelter is impossible, since the sealing along the length of the shelter between the outer and inner ducts is provided by a layer of material 11. Aspiration shelter works as follows. The material from the supply conveyor (not shown) along the charging chute 8 together with the ejected air enters the housing of the shelter formed by the main 1 and additional 2 walls of the cover, side 3, front 4 and rear 5 of the walls of the shelter; air with dust particles passes through dust precipitator 10, on which dust particles are deposited, then the dust-gas stream, reflecting from the front 4 and the additional 2 walls of the lid, is additionally released from dust particles and then enters the aspiration inlet pyratic network. 30 Formula of Invention Aspiration Shelter of the place of transshipment of bulk material according to ed. St. No. 1257230 is characterized in that, in order to increase the efficiency of dust collection and lower air suction inside the shelter, the body cover is provided with an additional wall fixed on the shelter walls and the loading chute to form outer box, while aspirated The funnel is mounted on an additional wall between the dust precipitator and the loading chute and communicates with the inter-shell space.
