Description

Air Backflow Dust Collector

technical field

The invention relates to the technical field of dust removal devices, in particular to an air backflow dust collector.

Background technique

Concrete mixing plant is a building material manufacturing equipment composed of five major components: mixing host, material weighing system, material conveying system, material storage system, control system and other auxiliary facilities. The main principle of its work is to use cement as the cementing material. Sandstone, lime, cinder and other raw materials are mixed and stirred, and finally made into concrete, which is put into construction and production as wall materials.

Existing dust removal devices for mixing plants only use high-power ventilation devices to remove dust generated during mixing, but during the production process of concrete mixing plants, a large amount of dust will be generated during material transportation and material storage, which will cause us to see The dusty mixing plant is flying, so that the staff will also inhale a large amount of dust in the non-working area, which will affect people's health.

Contents of the invention

In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide an air backflow dust collector to solve the problem of large dust in the mixing station and affecting the health of the staff.

In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions:

The air backflow dust collector includes a mixing station tank and a water tank. The top of the mixing station tank is provided with a return pipe with narrow ends and a wide middle. The upper part of the return pipe is provided with a bottom end extending into the return pipe. The first exhaust pipe, the bottom end of the return pipe extends into the tank of the mixing station; the end of the first exhaust pipe passes through the water tank and is provided with a cover, which is located in the water tank A plurality of through holes are provided on the pipe wall of the first exhaust pipe; the top of the water tank is provided with a second exhaust pipe, the bottom of the water tank is provided with a sewage pipe, and the side of the water tank is There is also a water inlet pipe on the wall.

Preferably, both the tank body and the bottom of the water tank are provided with brackets.

Preferably, the top end of the second exhaust pipe is bent downward to form an inverted U-shaped pipe.

Preferably, the central elevation of the water inlet pipe is higher than the central elevation of a portion of the first exhaust pipe below the water surface.

The beneficial effects of the present invention are: the design has simple structure, low manufacturing cost, strong applicability and obvious dust removal effect.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

As shown in Figures 1 to 2, the air backflow dust collector includes a mixing station tank 1 and a water tank 2. The top of the mixing station tank 1 is provided with a return pipe 3 that is narrow at both ends and wide in the middle. The return pipe 3 The upper part is provided with a first exhaust pipe 4 whose bottom end extends into the return pipe 3, and the bottom end of the return pipe 3 extends into the tank body 1 of the mixing station; the end of the first exhaust pipe 4 passes through the water tank 2 and is set There is a cover 5, and a plurality of through holes 6 are provided on the wall of the part of the first exhaust pipe 4 in the water tank 2; the top of the water tank 2 is provided with a second exhaust pipe 7, and the bottom end of the water tank 2 is provided with Sewage pipe 8 is arranged, and a water inlet pipe 9 is also provided on the side wall of water tank 2 .

Further, the tank body 1 of the mixing station and the bottom of the water tank 2 are both provided with brackets 10 .

Further, the top end of the second exhaust pipe 7 is bent downward to form an inverted U-shaped pipe.

Further, the central elevation of the water inlet pipe 9 is higher than the central elevation of the part of the first exhaust pipe 4 located below the water surface.

The principle of the present invention is as follows: when the dust in the tank body 1 of the mixing station moves upwards and flows through the return pipe 3, since the upper diameter of the return pipe 3 becomes smaller, the large particles are blocked by the upper pipe wall of the return pipe 3 and fall downward. into the tank body 1 of the mixing station to realize recycling; the gas carrying small particles flows into the water tank 2 through the first exhaust pipe 4, and since the part of the first exhaust pipe 4 in the water tank is located below the water surface, the gas from the through hole 6 The small particles and dust discharged inside are absorbed and retained by the water, while the clean air is discharged from the second exhaust pipe 7 to realize the dust removal process. During this process, the sewage in the water tank 2 enters the sewage pool through the sewage pipe 8, and is concentrated in the later stage. Therefore, it is necessary to pump water into the water tank 2 through the water inlet pipe 9 so that the water surface is always submerged in the part of the first exhaust pipe 4 located in the water tank 2 .

Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and equivalent technologies thereof, the present invention also intends to include these modifications and variations.
