Description

Technical Field

[0001] The utility model relates to an industrial dust collection and treatment device, belonging to the environmental protection field. Background Art

[0002] Industrial dust refers to solid particles suspended in the air generated during production and processing in a production workshop, mainly sourced from the mechanical crushing and grinding of solid materials, the mixing, screening, packaging, and transportation of powdered materials, and the soot generated from material combustion. Industrial dust includes heavy metal powders and non-metal powders such as lead, mercury, and arsenic. Long-term exposure or entry into the human body may lead to poisoning or even death, and an explosion may occur when the dust concentration in the environment is too high.

[0003] In the prior art, the treatment method for industrial dust is mostly filtration. However, existing collection and treatment devices mostly collect and store dust inside the device. Although it reduces the impact on the environment caused by gas emissions, its filtration efficiency is not high, and it is difficult to achieve comprehensive purification, unable to achieve the thorough treatment of dust. Summary of the Invention

[0004] In view of this, the utility model provides an industrial dust collection and treatment device to solve the above problems existing in the prior art.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] An industrial dust collection and treatment device includes a dust collection mechanism, a dust treatment mechanism, and a circulation mechanism connected in sequence;

[0007] The dust collection mechanism includes an air duct, a exhaust fan is arranged at the air inlet end of the air duct, and the air outlet end of the air duct is communicated with the dust mechanism;

[0008] The dust treatment mechanism includes a collection tank, a water pipe, and a water purification tank. The air outlet end of the air duct extends below the liquid level of the collection tank. A drain port is opened on the bottom surface of the collection tank. One end of the water pipe is communicated with the drain port, and the other end is communicated with the water purification tank. The water outlet end of the water pipe is provided with a filtering member;

[0009] The circulation mechanism includes a water pump. The water inlet end of the water pump is communicated with the water purification tank, and the water outlet end is communicated with the collection tank.

[0010] Based on the above technical solution, the utility model can be further improved as follows.

[0011] Further, the dust treatment mechanism further includes a stirrer. The stirring shaft of the stirrer is arranged at the center of the drain port, and the blades of the stirrer are arranged below the liquid level of the collection tank.

[0012] Further, the filtering member is a filter element and / or a filter screen. The filter element is arranged on the water outlet of the water pipe, and the filter screen is arranged below the water outlet end of the water pipe.

[0013] Further, a sealing plug is provided on the drain outlet.

[0014] Further, the air inlet end of the air duct is in a flared shape.

[0015] The beneficial effects of the present utility model are as follows:

[0016] By adopting the method of water filtration to collect industrial dust, an effective barrier is formed, thereby completely eliminating the pollution of dust to the environment, effectively protecting the ecological environment, significantly reducing the risk of explosion caused by excessive dust concentration, and adopting the water vortex technology to efficiently enrich the dust particles insoluble in water. Compared with the treatment limitations of traditional filtration and electrostatic adsorption, the present utility model ensures that even in the face of high-concentration dust, thorough treatment can be achieved. At the same time, the water can be recycled, and the dust can be collected and reused, saving resources, having low cost, simple structure, high working efficiency, and good purification effect.
