Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal dust treatment technology, and in particular to a dust treatment device for non-ferrous metal manufacturing. Background Technology
[0002] Metal dust control technology is an indispensable environmental protection aspect of industrial production, especially in the non-ferrous metal manufacturing sector. The processing of materials such as aluminum, copper, and zinc generates large amounts of fine, potentially hazardous metal dust. If this dust is emitted directly without effective treatment, it will not only pollute the environment but also threaten the health of operators and may even cause safety accidents such as explosions. Traditional metal dust control methods typically employ physical filtration, electrostatic adsorption, or wet dust collection technologies. Among these, wet dust collection is widely used due to its low cost and ease of operation.
[0003] However, existing technologies still have some shortcomings. Traditional wet dust collection devices mostly rely on the negative pressure of a blower to directly suck in dust and then suppress it through simple water mist spraying. This method has the following drawbacks:
[0004] Low dust handling efficiency: When vacuuming under negative pressure, fine dust is easily re-entrained in the airflow and is difficult to completely capture. The inside of the equipment is prone to accumulating dirt, requiring frequent cleaning and affecting production efficiency.
[0005] Poor sedimentation effect: After the dust and water are mixed, they do not undergo sufficient contact and sedimentation, and some particles will still be discharged with the airflow. Utility Model Content
[0006] In view of the shortcomings of the prior art, this utility model provides a dust treatment device for non-ferrous metal manufacturing, which overcomes the shortcomings of the prior art and effectively solves the problems of low dust treatment efficiency and poor sedimentation effect.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A dust treatment device for non-ferrous metal manufacturing includes a dust treatment box. A transparent sealed door is fixedly connected to one outer wall of the dust treatment box by screws. The interior of the dust treatment box is respectively provided with a dust settling area, a dust settling area, a vortex area and an exhaust area. The dust settling area is located on one side of the interior of the dust treatment box, the dust settling area is located on the other side of the interior of the dust treatment box, the vortex area is located between the dust settling area and the dust settling area, and the exhaust area is located at the top of the interior of the dust treatment box.
[0009] A dust absorption assembly is provided on one outer wall of the dust treatment box, and a motor base is welded to the top of the other outer wall of the dust treatment box. A blower is fixedly connected to the top outer wall of the motor base by bolts. An exhaust pipe is fixedly connected between the air inlet of the blower and the dust treatment box, and an exhaust pipe is fixedly connected to the air outlet of the blower.
[0010] Preferably, the dust absorption assembly includes a suction pipe, a corrugated pipe, and a suction head, wherein the suction pipe is welded to one outer wall of the dust treatment box, the corrugated pipe is fixedly connected to one outer wall of the suction pipe via a flange, and the suction head is fixedly connected to one outer wall of the corrugated pipe.
[0011] Preferably, a support frame is welded to one side of the outer wall of the dust treatment box at the bottom of the suction pipe, and the corrugated pipe is tightly attached to the top outer wall of the support frame, and the handle is installed on one side of the outer wall of the suction head.
[0012] Preferably, a reinforcing pad is fixedly connected to one side of the inner wall of the dust collection area by screws, and the reinforcing pad is located on one side of the suction pipe.
[0013] Preferably, a drain pipe is welded to the bottom outer wall of the dust treatment box, and a first valve is installed on the outer wall of the drain pipe.
[0014] Preferably, a water supply pipe is welded to the outer wall of the other side of the dust treatment box, and a second valve is installed on the outer wall of the water supply pipe.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1. The dust treatment device for non-ferrous metal manufacturing designed in this paper allows the dust to be sucked into the treatment box under negative pressure and immediately come into contact with the circulating water. The water flows through the vortex zone to form a vortex, which prolongs the contact time between the dust and the water, promotes the full wetting and sedimentation of the particles, and reduces the difficulty of dust cleaning.
[0017] 2. The dust treatment device for non-ferrous metal manufacturing designed in this paper combines the spiral water flow in the vortex zone with the static stratification in the dust settling zone to ensure that fine dust settles completely and avoids secondary emissions. At the same time, the extensibility of the corrugated pipe allows for flexible adjustment of the suction angle, enabling the suction head to rotate and adjust its position at will.
