Abstract

This invention relates to mining promet. The goal is to increase the efficiency of the work of estimating the intensification of the swirling of the dusty water-air flow and strengthening the sludge collection. For this, the impeller (RK) 2 is placed inside the sludge trap (W) 10 and is made with blades (L) 11, the free ends of which are located at the inner surface of W 10. The torus-dust collector operates as follows. The dusty air enters the rotating RK 2, where it is exposed to the torch of the sprayed liquid and twists. The dusty water-air flow passes between L 11, is freed from dust and sludge in W 10 and is taken out cleaned from dust and sludge. The sludge film is directed along the surface of the L 11 and, together with the dust remaining in the air-water stream, flows from the free ends directly into the receiving holes 13, which are strongly swirling on the inner surface of the W 10. This contributes to the efficiency of dust collection and sludge collection of the fan-dust collector. 2 Il.

Description

The invention relates to the mining industry, is intended to combat the dust generated in underground workings during the operation of mining machines and equipment, and is an improvement of the invention according to the author. St. No. 1305385.

The purpose of the invention is to increase the work efficiency due to the intensification of the swirling of the dusty water-air flow and the strengthening of the sludge collection.

FIG. 1 shows a fan-dust collector, general view, longitudinal section: in FIG. 2 is a section A-A in FIG. one.

The torus dust collector valve contains a housing 1 with an impeller 2 installed inside it, mounted on an electric motor shaft, located in front of the intake manifold 3 with a water inlet 4 placed inside the impeller 2 a sprayer located behind the housing 1 exhaust diffuser 6 with a spraying device 7 and a sludge separator chamber 8 with a sludge outlet pipe 9 installed below. The impeller 2 is located inside the sludge trap 10, and around the periphery of the impeller 2 blades 11 are installed, the free ends 12 of which are located at the inner surface of the sludge trap 10 having receiving openings 13. A pipe 14 for collecting the sludge is placed in front of the sludge separator 8 from below.

Fan torus dust collector works as follows.

The dusty air is sucked through the intake manifold 3 and gets inside the rotating impeller 2, where it is exposed to a plume of sprayed liquid and twists. Then, the dusty water-air flow passes between the blades 11 and, freed from dust and sludge, moves in the axial direction, hits the spraying anarate 7, which converts the rotation of the air flow into a linear motion, and is brought out.

The dust particles, moving together with the air, pass through the spray of the sprayed liquid created by the liquid sprayer 5, wetted in collisions with water droplets, and are directed inside the rotating impeller 2, where in the field of centrifugal force are deposited inside the impeller 2 and on the blades 11 in the form of a film of sludge. Sludge films along the surface of the blades 11 of the centrifugal force are guided directly into the receiving openings 13 of the separator 10, and then through the annular gap between the separator 10 and the housing 1 is brought out through the nozzle 14.

The remaining particles of dust and sludge along with the swirling air flow from the impeller 2 are thrown into the sludge separation chamber 8 and deposited on the walls of this chamber, from where the sludge separator also comes out through the sludge discharge pipe 9.

Placing the impeller 2 inside the sludge trap 10 provides maximum centrifugal acceleration of dust particles and sludge on their way to the receiving holes 13 of the sludge trap 10 and allows the most efficient use of the centrifugal force of rotation of the water-air flow in the impeller 2 and causes an increase in dust collecting efficiency.

The implementation of the impeller 2 with blades 11, the free ends 12 of which are located at the receiving openings 13 of the sludge trap 10, eliminates the radial spread between the impeller 2 and the receiving openings 13 and simultaneously intensifies the twisting of the dusty water-air flow in the impeller 2, which allows on the one hand, it is best to use the centrifugal force acting on the particles of dust and sludge before the aerodynamic resistance of the air extinguishes the maximum centrifugal mustache the corrosion of dust and sludge particles on their way to the receiving holes of the sludge separator. between dust particles and water droplets in the field of increased centrifugal force, as well as due to the intensification of sludge deposition on the blades 11 of the impeller 2 and transporting the sludge film along these The blades go straight to the receiving openings 13 of the sludge trap 10.

All this makes it possible to increase the efficiency of the fan-dust collector.
