[0014] 1. The utility model realizes the removal of aluminum dust and oil stains in the air by the combination of the filter screen, the filter core and the oil stain filter. In the open state of the negative pressure fan, the air passes through the filter screen through the dust suction port, the filter screen is used for removing large-particle aluminum dust, and the subsequent filtering pressure is reduced. After the air passes through the filter screen, it penetrates from the outer wall of the filter cartridge to the inside. Two filter cartridges adopt a 200-mesh filter core structure, which can filter small-particle and micro-particle aluminum dust in the air. Subsequently, the air enters the air duct from the filter cartridge and is discharged from the first air outlet pipe. Under the action of the negative pressure fan, the air is blown to the oil stain filter. The oil stain filter can adsorb oil mist, water mist and residual dust in the air. The dust suction structure significantly improves the dust suction efficiency and meets the high-standard cleaning and safety requirements of the aluminum cutting industry on the explosion-proof dust collector.

[0015] 2. The utility model is provided with an aluminum dust collection box below the lower filter screen and the filter cartridge. Since the filter screen is obliquely designed, the dust particles blocked outside the filter screen automatically fall into the inside of the aluminum dust collection box under the action of gravity. When the air passes through the filter cartridge, it is also blocked on the outer wall of the filter core and falls into the aluminum dust collection box under the action of gravity. On the one hand, the filtering effect is not affected by the blocking of particulate matter, and on the other hand, the aluminum dust is convenient for the staff to collect.

[0016] 3. The utility model discloses a filter screen filter cartridge, negative pressure fan and oil dirt filter are arranged in the independent cavity, and the modular design is convenient for daily maintenance and overhaul, and the seal door of one side of the shell can ensure the seal shape of the shell inside, ensures the dust absorption effect, and can observe the filter core state according to the window on the seal door simultaneously, and the maintenance door of the other side is movably installed with the shell, and it is convenient to replace and maintain the filter material individually.

[0024] The four dust suction ports 2 arranged at the front end greatly improve the dust suction efficiency and coverage, ensuring that the aluminum cutting operation area can be fully and quickly cleaned. The filter screen 6 serves as the first line of defense, effectively blocking and collecting large aluminum dust particles, protecting the subsequent filtration system and extending the service life of the entire equipment. The high-precision filter core built into the filter cartridge 7 adopts a 200-mesh fine structure, which can deeply filter the tiny particles in the air, ensuring that the dust suction effect meets the high standards of the industry, providing a safer and cleaner working environment for the aluminum cutting industry. The oil stain filter 5 uses adsorbent materials to deeply remove oil mist, water mist, and residual dust in the air. When the air containing oil stains flows through the oil stain filter, the oil stain particles will be adsorbed on the surface or inside of the filter, while the clean air will be discharged through the filter.

[0025] Please refer to Figure 2 and Figure 3 , the filter screen 6 is arranged obliquely, and the frames at the upper and lower ends of the filter screen 6 are slidingly connected with the shell 1. Due to the oblique design of the filter screen 6, the dust particles blocked outside the filter screen 6 automatically fall into the aluminum dust collection box 8 under the action of gravity.

[0026] Please refer to Figure 2 and Figure 3 , the negative pressure fan is composed of an explosion-proof motor 12 and an impeller assembly 11, and the output shaft of the explosion-proof motor 12 is fixed with the impeller shaft inside the impeller assembly 11 through a shaft coupling. The air inlet end of the impeller assembly 11 corresponds to the first air outlet pipe 9, and the other end of the impeller assembly 11 is provided with a second air outlet pipe 14 corresponding to the position of the oil stain filter 5. The explosion-proof motor 12 is provided with a negative pressure fan mounting bracket 10 outside, and the negative pressure fan mounting bracket 10 is fixed with the shell 1 by bolts. The explosion-proof motor 12 serves as a power source, not only having strong driving force, but also having excellent explosion-proof performance, effectively preventing safety accidents caused by motor failure. The stable support of the mounting bracket ensures that the negative pressure fan will not shake or displace during high-speed operation, thereby ensuring long-term stable operation of the equipment.

[0027] Please refer to Figure 1 and Figure 4 , one side of the shell 1 is provided with a sealing door 3, and the other side of the shell 1 is provided with an access door 15. Both the sealing door 3 and the access door 15 are hingedly connected with the shell 1. The sealing door 3 is provided with a window 4 corresponding to the positions of the filter screen 6 and the filter cartridge 7. The modular design facilitates daily maintenance and repair. The sealing door 3 on one side of the shell 1 can ensure the sealing of the inside of the shell 1 and ensure the dust suction effect. The state of the filter core can be observed through the window 4 on the sealing door 3. The access door 15 on the other side is movably installed with the shell 1, which facilitates the replacement and maintenance of the filter material.

[0028] Working principle: when using, the strong suction of the negative pressure fan drives air and dust to enter the equipment through the dust suction port 2, then the air and dust first meet the filter screen 6, the filter screen 6 is arranged obliquely, effectively blocks and collects large particle aluminum dust, then the air preliminarily filtered through the filter screen 6 enters the filter cartridge 7 area. The high-precision filter element arranged in the inner wall of the filter cartridge 7 adopts 200-mesh fine structure, can deeply filter the tiny particles in the air, the air outlet end of the filter cartridge 7 is connected with the air duct 13, the air duct 13 guides the filtered air to the oil stain filter 5 at the rear end of the equipment, the oil stain filter 5 uses adsorption material to deeply remove oil mist, water mist and residual dust in the air, when the air containing oil stains flows through the oil stain filter, the oil stain particles are adsorbed on the surface or inside of the filter, and the clean air is discharged through the filter, ensuring that the cleanliness of the discharged air reaches high standard, solving the pollution of the atomized oil stains generated by the micro-lubrication of the cutting fluid to the air environment.
