Description

Technical Field

[0001] This utility model relates to the field of purification equipment technology, and more specifically, to an air purification device that uses electromagnetic adsorption of metal powder. Background Technology

[0002] Automobile production workshops generally include stamping workshops, welding workshops, painting workshops, and final assembly workshops. Some automakers also have chassis workshops and battery workshops. The stamping workshop is the area where metal powder is most significantly generated. During the process of manufacturing automotive parts (such as doors and hoods) by using a press to drive a die to stamp metal sheets, causing plastic deformation or separation, the metal sheet and the die constantly rub and compress, causing tiny particles on the metal surface to fall off and form metal powder. Especially in processes such as blanking, when the sheet metal is cut and separated, a large amount of fine metal shavings are generated at the cut edges; these shavings are part of the metal powder. Furthermore, if the metal sheet itself contains impurities or has an uneven surface, the amount of metal powder generated will also increase during the stamping process.

[0003] Air purification equipment is installed in automobile production workshops to purify the air. Existing air purifiers have built-in filters, but the presence of metal powder in the workshop air easily clogs these filters. Existing air purifiers are not adept at adsorbing metal powder, and clogging affects the filter's filtration efficiency. Therefore, we propose an air purification device that uses electromagnetic adsorption of metal powder. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide an air purification device that uses electromagnetic adsorption of metal powder to solve the technical problem that the built-in filter of current air purification equipment is easily clogged by metal powder, affecting the air purification effect.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an air purification device for electromagnetic adsorption of metal powder, comprising an outer cover, a base, a top ring, a bottom ring, and an electromagnetic shell. A fan is installed inside the base. The bottom ring is inserted into the upper opening of the base. The top ring is located above the bottom ring, and the top and bottom rings are connected by a connecting cylinder. A positioning tube is fixed to the upper inner side of the bottom ring by a bracket. A filter cartridge is installed inside the connecting cylinder, and the lower end of the filter cartridge is connected to the positioning tube. A limiting disc is fixed to the upper end of the filter cartridge and is inserted into the top ring. The electromagnetic shell is sleeved on the outside of the connecting cylinder, and the upper and lower ends of the electromagnetic shell are respectively attached to the top and bottom rings. Electromagnets are arranged in a circular array inside the electromagnetic shell. A cylindrical cover is sleeved on the outside of the electromagnetic shell, and the outer cover is sleeved on the outside of the electromagnetic shell.

[0006] In use, this invention is powered by an external power source. The operator starts the device via an external control device. The suction pipe is connected to the external pipe port of the external plate. The fan is started, causing the airflow to pass through the external plate and into the recess of the limiting plate. Then, it is introduced into the gap between the filter cartridge and the connecting cylinder through the air outlet. The electromagnet is energized to generate magnetic force, which is conducted to the electromagnet shell. Through the plastic connecting cylinder, the metal powder in the airflow is magnetically attracted to the inner wall of the connecting cylinder. After passing through the filter cartridge, the airflow is discharged downward through the opening of the positioning tube and outward through the side exhaust port of the fan. Through the above structural design, this device sets up an electromagnetic adsorption structure in the airflow path, and uses electromagnetic adsorption to attract the metal powder in the airflow to the connecting cylinder. To prevent metal powder from clogging the filter cartridge and affecting the filtration and purification effect during continuous use, and to ensure processing quality, the device will accumulate metal powder and particulate dust after long-term use, requiring regular cleaning. Lift the plug-in mounting cover upwards to separate the plug rod from the docking cylinder. Then lift the top ring upwards; the top ring, along with the connecting cylinder and bottom ring, will separate from the plug-in part at the top of the base. Then rotate the threaded separation sealing plate. At this time, the gap between the bottom ring and the positioning tube opens. After disconnecting the current in the electromagnet, the metal powder and particulate dust are discharged outwards from the gap between the bottom ring and the positioning tube, completing the internal cleaning. The above structure facilitates separation and disassembly, making internal cleaning and waste removal easier and reducing maintenance difficulty.

[0007] Preferably, a docking cylinder is installed through the upper ends of both sides of the base, and a plug rod is fixed to the lower ends of both sides of the outer cover, with the lower end of the plug rod inserted into the corresponding docking cylinder.

[0008] Preferably, a sealing plate is installed at the lower inner end of the bottom ring, and the sealing plate is threaded onto the positioning tube. A discharge port is formed between the bottom ring and the positioning tube, and the sealing plate is adapted to the discharge port.

[0009] Preferably, the upper end face of the limiting plate has an annular array of air vents, and the lower end of the air vents is connected to the gap between the filter element cylinder and the connecting cylinder.

[0010] Preferably, the connecting cylinder is made of polyethylene, and the electromagnetic shell is fitted to the outer wall of the connecting cylinder.

[0011] Preferably, the top ring, bottom ring, and electromagnetic shell are all located inside the outer cover, and an external receiving plate is provided at the upper opening of the outer cover.

[0012] Preferably, the outer connecting plate has an outer connecting port at the middle, and the outer connecting port corresponds to the upper recess of the limiting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model designs an electromagnetic shell and connects the dust collection pipe to the outer pipe port of the external connecting plate. When the fan is started, the airflow passes through the external connecting plate and is guided into the recess of the limiting plate. Then, it is guided into the gap between the filter cartridge and the connecting cylinder through the air outlet. When the electromagnet is energized, it generates magnetic force, which is conducted to the electromagnetic shell. Through the plastic connecting cylinder, the metal powder in the airflow is magnetically attracted to the inner wall of the connecting cylinder. After passing through the filter cartridge, the airflow is discharged downward through the opening of the positioning tube and then discharged outward through the side exhaust port of the fan. Through the above structural design, this device sets up an electromagnetic adsorption structure in the airflow path. Through electromagnetic adsorption, the metal powder in the airflow is adsorbed onto the inner wall of the connecting cylinder, which avoids the metal powder clogging the filter cartridge and affecting the filtration and purification effect during continuous use, thus ensuring the processing quality.

[0015] 2. This utility model also incorporates a bottom ring and a sealing plate. After long-term use, metal powder and particulate dust accumulate inside the device, requiring regular cleaning. The outer cover of the plug-in installation is lifted upwards to separate the plug rod and the docking cylinder. Then, the top ring is lifted upwards, and the top ring, along with the connecting cylinder and the bottom ring, separates from the plug-in part at the top of the base. Then, the threaded sealing plate is rotated to separate the sealing plate. At this time, the gap between the bottom ring and the positioning tube opens. After the current inside the electromagnet is cut off, the metal powder and particulate dust are discharged outwards from the gap between the bottom ring and the positioning tube, completing the internal cleaning. The above structure facilitates separation and disassembly, making internal cleaning and waste removal easier and reducing maintenance difficulty. Attached Figure Description

A limiting plate 4 is fixed to the upper end of the filter element tube 401 and is inserted into the top ring 5. A sealing plate 8 is installed on the lower inner side of the bottom ring 502 and is threaded onto the positioning tube 503. A discharge port is formed between the bottom ring 502 and the positioning tube 503, and the sealing plate 8 is compatible with the discharge port. The upper end of the limiting plate 4 has an annular array of air vents 402 in the recess, and the lower end of the air vents 402 is connected to the gap between the filter cartridge 401 and the connecting cylinder 501. The suction pipe is connected to the outer pipe port of the outer connecting plate 102. When the fan 3 is started, the airflow passes through the outer connecting plate 102 and is guided into the recess of the limiting plate 4, and then through the air vents 402 into the gap between the filter cartridge 401 and the connecting cylinder 501. When the electromagnet 701 is energized, it generates magnetic force, which is conducted to the electromagnet housing 7 and transmitted through the plastic connecting material. The filter cartridge 501 magnetically attracts the metal powder in the airflow to the inner wall of the connecting cartridge 501. After passing through the filter cartridge 401, the airflow is discharged downward through the opening of the positioning tube 503 and then discharged outward through the side exhaust port of the fan 3. Through the above structural design, the device sets up an electromagnetic adsorption structure in the airflow path, and uses electromagnetic adsorption to attract the metal powder in the airflow to the inner wall of the connecting cartridge 501, so as to avoid the metal powder clogging the filter cartridge 401 and affecting the filtration and purification effect during continuous use, and to ensure the processing quality.

[0024] like Figures 2 to 6As shown, this utility model relates to an air purification device for electromagnetic adsorption of metal powder, comprising an outer cover 1, a base 2, a top ring 5, a bottom ring 502, and an electromagnetic shell 7. The electromagnetic shell 7 is sleeved on the outside of the connecting cylinder 501, and the top and bottom ends of the electromagnetic shell 7 are respectively attached to the top ring 5 and the bottom ring 502.

The top ring 5, along with the connecting cylinder 501 and the bottom ring 502, separates from the top plug-in part of the base 2. Then rotate the threaded separation sealing plate 8. At this time, the gap between the bottom ring 502 and the positioning tube 503 opens. After disconnecting the current in the electromagnet 701, the metal powder and particulate dust are discharged outwards from the gap between the bottom ring 502 and the positioning tube 503, completing the internal cleaning. The above structure completes the separation and disassembly, facilitating internal cleaning and impurity removal, and reducing the difficulty of maintenance.

Then, it flows through the air outlet 402 into the gap between the filter cartridge 401 and the connecting cylinder 501. The electromagnet 701 is energized, generating magnetic force. This magnetic force is conducted to the electromagnet housing 7 and passes through the plastic connecting cylinder 501, causing the metal powder in the airflow to be magnetically adsorbed onto the inner wall of the connecting cylinder 501. The airflow then passes through the filter cartridge 401 and then through the positioning tube 5. 03 The outlet is downward and discharged outward through the side exhaust port of the fan 3. After long-term use, metal powder and particulate dust accumulate inside the device, requiring regular cleaning. Lift the plug-in installed outer cover 1 upward to separate the plug rod 101 and the docking cylinder 201. Then lift the top ring 5 upward.
