Description

Technical Field

[0001] This utility model relates to the field of metal smelting technology, specifically to a dust removal device for metal processing. Background Technology

[0002] Metal smelting is the process of changing metals from a combined state to a free state. A common method is to use reducing agents such as carbon, carbon monoxide, and hydrogen to react with metal oxides at high temperatures to obtain elemental metals.

[0003] A search revealed a utility model patent with publication number CN214552182U, which discloses an acid mist dust removal device for metal recycling and smelting. This utility model has a reasonable design. It can initially filter dust through a filter screen, and prevent the filter screen from clogging by constantly hitting it with steel balls. By starting a water pump, the vertical plate can spray the purified liquid in the water inlet pipe through the spray pipe, thereby further purifying the exhaust gas.

[0004] However, the above design still has shortcomings. After the dust is filtered by the filter screen and the exhaust gas is purified by the purification liquid, the staff needs to handle the purified filter screen and the waste liquid after the purification liquid is treated. However, after the purification is completed, it is inconvenient for the staff to disassemble and install the filter device, which leads to a reduction in the dust removal efficiency of the device.

A gear 19 is connected, which meshes with a set of toothed plates 18. A handle 20 is connected to the bottom of the gear 19. Through the set recycling box 14, with the cooperation of the gear 19 and the toothed plates 18, the toothed plates 18 located inside the slot 17 and the gear 19 located inside the opening 21 make a set of toothed plates 18 mesh with the gear 19. Driven by the handle 20, the rotating gear 19 drives the two toothed plates 18 to move. The set of toothed plates 18 is displaced inside the slot 17, moving away from the housing 1, which facilitates the disassembly and assembly of the recycling box 14 by the staff, thereby cleaning the filter screen 15 inside the recycling box 14 and recycling the liquid.

[0021] See Figure 1 , Figure 2 , Figure 4 The outer shell 1 is fitted with a fixing sleeve 6, and the bottom of the fixing sleeve 6 is connected to a support frame 7. The bottom of the recycling box 14 is connected to a set of support legs 16. Through the fixing sleeve 6, the fixing sleeve 6 and the support frame 7 connected to the bottom play a role in fixing the shell 1.

[0022] See Figure 1 The outer side of the shell 1 is connected to an air inlet pipe 4 and an exhaust pipe 5 respectively. A movable cover plate 2 is bolted to the top of the shell 1. Through the air inlet pipe 4 and the exhaust pipe 5, one end of the exhaust pipe 5 is connected to a fan to facilitate the extraction of gas from inside the container.

[0023] See Figure 2Inside the housing 1, there is a baffle 22. At the bottom of the baffle 22, there is a set of nozzles 10 arranged at equal intervals. Through the nozzles 10, the set of nozzles 10 arranged at equal intervals can more comprehensively reduce dust.

[0024] See Figure 2 A water storage tank 8 is connected above the baffle 22. A pump body 9 is connected inside the water storage tank 8. The output end of the pump body 9 is connected to a set of nozzles 10. A water inlet pipe 3 is connected above the movable cover 2. The bottom end of the water inlet pipe 3 is connected to the water storage tank 8.

[0026] See Figure 3 The inner wall of the limiting plate 12 is provided with a set of slides 13. The set of slides 13 are slidably connected to the recycling bin 14 through the slider. The set of slides 13 facilitates the disassembly and assembly of the recycling bin 14 by the staff, reduces the friction between the recycling bin 14 and the shell 1, and extends the service life of the recycling bin 14.

[0027] Working principle: During use, the operator connects the air inlet pipe 4 to the container and uses the fan connected to the exhaust pipe 5 to draw the gas inside the container into the housing 1. Then, under the pump body 9, the pump body 9 sprays the water inside the water storage tank 8 through a set of nozzles 10, so that the sprayed water comes into contact with the dust in the air. The water carrying the dust falls onto the surface of the filter screen 15 by gravity. The filter screen 15 filters the dust and the filtered water falls into the recycling tank 14. Depending on the actual situation, the water pipe can be connected to the bottom of the recycling tank 14 and the other end can be connected to the pump body 9 to realize the recycling of water. After the dust removal work is completed, the operator turns the handle 20 to drive the gear 19 to mesh with the toothed plate 18, so that one end of the toothed plate 18 is away from the housing 1, which facilitates the subsequent disassembly and assembly of the recycling tank 14 and cleaning of the filter screen 15.
