Description

Technical Field

[0001] This utility model relates to the technical field of magnesium alloy smelting, and in particular to a dust removal device for magnesium alloy smelting. Background Technology

[0002] Currently, in the magnesium alloy smelting process, from charging and melting to modification refining and static casting, flux or extinguishing agents must be added at each stage to prevent the magnesium liquid from oxidizing, generating a large amount of acidic waste gas. To ensure the health of workshop workers, this waste gas must be led out of the workshop for environmental treatment. The general treatment method is: boiler exhaust gas → branch pipe → main pipe → induced draft fan → ordinary packed spray tower → discharge. However, existing smelting waste gas treatment methods have limitations in practice. Due to uneven production, such as prolonged periods of low furnace operation, dust-laden waste gas in the main pipe tends to accumulate at the bottom due to low flow velocity, accumulating to a thickness of approximately 200-300 mm over several months. This increases operating resistance, is corrosive to the pipes, and poses safety hazards. Using baghouse dust collectors also requires regular replacement and cleaning of the filter bags, which is cumbersome.

[0003] Therefore, we propose a dust removal device for magnesium alloy smelting to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dust removal device for magnesium alloy smelting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dust removal device for magnesium alloy smelting includes a main body with an air inlet pipe at its upper end. A filter cartridge is vertically arranged inside the main body and rotatably mounted on a spiral fixed scraper. Both ends of the fixed scraper are fixedly connected to the main body, and both ends of the filter cartridge are rotatably connected to the main body. A drive mechanism for rotating the filter cartridge is provided on the main body. An outlet funnel is fixedly connected to the lower end of the main body. Circular holes matching the filter cartridge are provided at both the upper and lower ends of the main body, and the two circular holes are respectively matched and connected to the air inlet pipe and the outlet funnel. An air outlet pipe is fixedly connected to the side wall of the main body.

[0007] Preferably, the outer wall of the filter cartridge is evenly distributed with a mesh-like reinforcing rib structure.

[0008] Preferably, the air intake pipe is connected to an air blower pipe, which is connected to an external air pump and tilted toward the main body of the device.

[0009] Preferably, the driving mechanism includes a drive motor fixedly mounted on the main body of the device, a drive gear coaxially fixedly connected to the output end of the drive motor, a driven gear fixedly sleeved on the outside of the filter cartridge, and the drive gear meshing with the driven gear.

[0010] Preferably, a sealed door is provided on the side wall of the main body of the device.

[0011] Preferably, the air outlet pipe is equipped with an auxiliary air extraction device.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting the rate of exhaust gas entry and the rate of gas exit after dust removal, the dust removal efficiency can be controlled and the processing air volume can be kept stable, no longer limited by the exhaust gas volume. Moreover, because the filter cartridge is made of stainless steel, it has high overall strength and can increase the gas flow rate during the dust removal process, thereby increasing the processing efficiency. It also has good processing effect and is not easily damaged. The centrifugal rotation of the filter cartridge can assist in dust removal. At the same time, with the help of the spiral fixed scraper, the dust adhering inside the filter cartridge can be pushed downward to achieve dust self-cleaning. The overall performance is high.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3 The dust removal device for magnesium alloy smelting shown includes:

[0020] The device body 1 is rectangular in shape. An air inlet pipe 2 is provided at the upper end of the device body 1. A filter cartridge 3 is vertically arranged inside the device body 1. The filter cartridge 3 can filter various dusts. The entire device body is made of stainless steel. The outer wall of the filter cartridge 3 is evenly distributed with a mesh reinforcing rib structure, which has high strength. The filter cartridge 3 is rotatably mounted on a spiral fixed scraper 4. Both ends of the fixed scraper 4 are fixedly connected to the device body 1. Both ends of the filter cartridge 3 are rotatably connected to the device body 1. The device body 1 is provided with a drive mechanism to drive the filter cartridge 3 to rotate.

[0021] The above structure mainly realizes the rotation of the filter cartridge 3, which can increase the filtration effect through centrifugal force. Moreover, the dust is thrown onto the inner wall of the filter screen 3 and pushed downward by the fixed scraper 4.

[0022] The device body 1 has a discharge funnel 5 fixedly connected to its lower end to discharge dust. Both the upper and lower ends of the device body 1 are provided with round holes for matching filter cartridges 3. The two round holes are respectively matched and connected to the air inlet pipe 2 and the discharge funnel 5. An air outlet pipe 6 is fixedly connected to the side wall of the device body 1 for air intake and exhaust.

[0023] During air intake, the intake pipe 2 is connected to the blower pipe 7, which is connected to an external blower pump and tilted toward the main body 1 of the device. This can increase the rate at which the exhaust gas enters, thereby giving the exhaust gas an initial centrifugal acceleration in the filter cartridge 3. Similarly, an auxiliary air extraction device is provided on the exhaust pipe 6 to ensure the exhaust rate. All of the above structures are based on the strength of the filter cartridge 3.

[0024] To achieve the driving rotation of the filter cartridge 3 mentioned above, specifically, the driving mechanism includes a driving motor 8 fixedly installed on the main body 1 of the device, a driving gear 9 coaxially fixedly connected to the output end of the driving motor 8, and a driven gear 10 fixedly sleeved on the outside of the filter cartridge 3, with the driving gear 9 meshing with the driven gear 10.

[0025] To facilitate the processing of the internal structure of the main body 1 and to facilitate cleaning of the interior, a sealed door 11 is provided on the side wall of the main body 1, which can be opened for operation.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
