Description

Technical Field

[0001] The utility model relates to a dust collector pipeline filtering device which can effectively block foreign matters. Background Art

[0002] At present, the air inlet pipeline of the coal conveying belt dust collector sucks in dust-containing gas, enters the dust collector water tank, impacts the liquid surface and generates a large number of foams and water droplets, so as to achieve the purpose of purifying air. There is a layer of wire mesh at the inlet of the air inlet pipeline, but its thickness is relatively thin and it is not corrosion-resistant. The wire mesh is often damaged. At the same time, for cleaning the sundries blocked on the wire mesh, personnel need to stand above the belt and drill into the air inlet pipeline, with a relatively high safety risk. Content of the Utility Model

[0003] The purpose of the utility model is to solve the above-mentioned existing problems and provide a dust collector pipeline filtering device which can effectively block foreign matters.

[0004] The above purpose is achieved by the following technical solutions:

[0005] A dust collector pipeline filtering device which can effectively block foreign matters, comprising an upper cylinder body and a lower cylinder body. A filter gas box is connected between the upper cylinder body and the lower cylinder body. The filter gas box includes a square box body. A V-shaped filter gas mesh plate is fixed in the square box body. Both sides of the square box body are provided with openings. Aggregate grooves are fixed at the openings. A discharge pipe is fixed at the end of the aggregate groove. A cover is threadedly connected to the discharge pipe.

[0006] For the dust collector pipeline filtering device which can effectively block foreign matters, the V-shaped filter gas mesh plate is formed by welding a plurality of steel rods vertically and horizontally.

[0007] For the dust collector pipeline filtering device which can effectively block foreign matters, the bottom surface of the aggregate groove is an inclined surface. Advantageous Effects

[0008] 1. The utility model installs a filter gas box at the inlet of the dust collector air inlet pipeline, which can effectively filter the incoming dust-containing gas. This filtration can effectively block sundries such as stones in the dust-containing gas and prevent them from entering the dust collector water tank.

[0009] 2. The filter gas mesh plate of the utility model is a V-shaped plate with the tip facing upwards, so that the blocked sundries such as stones can roll down along the filter gas mesh plate to both sides and fall into the aggregate groove, and then roll along the aggregate groove to the discharge pipe, which is convenient for collecting sundries such as stones.

[0010] 3. The filter gas mesh plate of the utility model is formed by welding a plurality of stainless steel rods vertically and horizontally, preventing damage. Description of the Drawings

[0018] Referring to Figures 1-6 , a dust collector pipe filtering device that effectively blocks foreign objects, which comprises an upper cylinder 2 and a lower cylinder 3. A filter box 1 is connected between the upper cylinder and the lower cylinder. The upper part of the filter box is connected to the upper cylinder by bolts, and the lower part of the filter box is connected to the lower cylinder by bolts. The part of the filter box corresponding to the upper cylinder is provided with a circular hole equal to the inner diameter of the upper cylinder, and the part of the filter box corresponding to the lower cylinder is provided with a circular hole equal to the inner diameter of the lower cylinder. In this way, when air enters, the dust-containing gas enters the filter box from the upper cylinder, and after being filtered, it enters the lower cylinder, and then enters the dust collector water tank. The filter box includes a square box 8, and a V-shaped air filter mesh plate 7 is fixed inside the square box. Both sides of the square box have openings 9, and an aggregate tank 4 is fixed at the openings. A discharge pipe 5 is fixed at the end of the aggregate tank, and a cover 6 is threadedly connected to the discharge pipe.

[0019] In the dust collector pipe filtering device that effectively blocks foreign objects, the V-shaped air filter mesh plate is formed by welding a plurality of steel rods crosswise.

[0020] In the dust collector pipe filtering device that effectively blocks foreign objects, the bottom surface of the aggregate tank is an inclined surface.

[0021] Working principle: When in use, after fixing the air filter box to the upper cylinder body and the lower cylinder body with bolts, when inhaling air, the dust-containing gas enters the air filter box from the upper cylinder body. The dust-containing gas passes through the air filter mesh plate, and the stones doped in the dust-containing gas will be blocked by the air filter mesh plate. After being blocked, they will roll to both sides along the air filter mesh plate and fall into the aggregate tank. Since the bottom surface of the aggregate tank is an inclined surface, the collected stones will roll along the inclined surface to the discharge pipe, which is convenient for the collection of stones, etc. When it is necessary to clean sundries such as stones, just unscrew the cover, and the stones will roll out through the discharge pipe, which is convenient for cleaning.
