[0029] The oil mist generated in the CNC workshop is sucked into the air inlet 2 through the adsorption force formed by the wind motor inside the motor box 1, and enters the filter boxes 5 on the left and right sides through the ventilation device. The oil mist first passes through the high-pressure plate 7, and then passes through the low-pressure plate 8 to adsorb large particles in the oil mist, and then passes through the first filter cotton 10 and the second filter cotton 11 in the first filter plate 9 to filter and adsorb the oil. When the first filter cotton 10 is saturated with the second filter cotton 11 to adsorb the oil, the oil will fall and can be collected through the oil outlet 4, thereby realizing the recycling of the oil. The air passing through the first filter cotton 10 and the second filter cotton 11 continues to go up, is filtered by the second filter plate 12, and is filtered by the adsorption force formed by the fan 34. It continues to pass through the upper third filter plate 13 of the filter box 5 and is filtered by the first filter cotton 10. The third filter cotton 14 and the fourth filter cotton 15 absorb impurities in the oil. When the third filter cotton 14 and the fourth filter cotton 15 are saturated with oil, the oil continues to fall and will be further recycled. At this time, the air continues to go up through the fan 34 and is discharged from the filter device and discharged from the workshop through the air outlet 3 to prevent oil mist from polluting the processing workshop. After the third filter cotton 14 and the fourth filter cotton 15 are saturated with oil, the oil continues to fall and will fall onto the first filter plate 9, causing the first filter cotton 10 and the second filter cotton 11 to absorb oil again, thereby causing residual oil in the first filter cotton 10 and the second filter cotton 11. The first electric push rod 25 drives the extrusion plate 26 to fit the bottom of the first filter cotton 10 and the top of the second filter cotton 11 respectively, and then the filter is started. The first motor 16 drives the first rotating rod 17 and the first transmission wheel 18 to rotate, and the second transmission wheel 20 and the second rotating rod 21 are driven to rotate under the transmission action of the belt 19, so that the first rotating rod 17 and the second rotating rod 21 rotate at the same time to drive the moving block 23 to move in the mounting block 22, and the moving block 23 drives the connecting plate 24 to move back and forth at the bottom of the first filter cotton 10 and the top of the second filter cotton 11, so that the extrusion plate 26 squeezes the first filter cotton 10 and the second filter cotton 11 to squeeze out the residual oil in the first filter cotton 10 and the second filter cotton 11. At the same time, when the moving block 23 above the second filter cotton 11 moves, it drives the second electric push rod 27 and the knocking plate 28 to move, and the knocking plate 28 is pushed up and down by the second electric push rod 27 to knock The second filter plate 12 is used to prevent the second filter plate 12 from accumulating oil. When the squeezing plate 26 squeezes the first filter cotton 10 and the second filter cotton 11, the self-priming pump 32 is started to absorb the oil inside the first filter cotton 10 and the second filter cotton 11 through the connecting pipe 29 and the collecting pipe 30. At the same time, the first filter cotton 10 and the second filter cotton 11 can be adsorbed on the first filter plate 9 to prevent deformation during squeezing. The oil is transported to the bottom of the filter box 5 through the delivery pipe 31 and the elastic telescopic pipe 33. The oil will be collected at the oil outlet 4, so that the residual oil in the first filter cotton 10 and the second filter cotton 11 is squeezed clean and adsorbed, thereby further improving the adsorption effect of the first filter plate 9, the first filter cotton 10 and the second filter cotton 11, and then improving the filtering effect of the filter box 5.More environmentally friendly and easy to use.

The first motor 16 is used to install the first motor 16, and the first rotating rod 17 and the first transmission wheel 18 can be driven to rotate by the first motor 16. Under the transmission action of the belt 19, the second rotating rod 21 and the second transmission wheel 20 can be driven to rotate, so that the moving block 23 can drive the connecting plate 24 to move, and then drive the extrusion plate 26 and the knocking plate 28 to move, so as to clean the first filter cotton 10, the second filter cotton 11 and the second filter plate 12, thereby improving the cleaning effect.

[0032] like Figure 3-7 As shown, one end of the second rotating rod 21 is rotatably connected to the inner wall of the first mounting groove and the second mounting groove, the first rotating rod 17 and the second rotating rod 21 are rotatably connected to the inner wall of the side away from the slide groove of the two filter boxes 5 at one end away from the first motor 16 through the first movable opening, the first rotating rod 17 and the second rotating rod 21 are located at both ends of the first filter cotton 10 and the second filter cotton 11, the first transmission wheel 18 and the second transmission wheel 20, and the belt 19 are respectively located inside the first mounting groove and the second mounting groove, the moving block 23 and the extrusion plate 26 close to the first mounting groove are located at the top of the second filter cotton 11, and the moving block 23 and the extrusion plate 26 close to the second mounting groove are located at the bottom of the first filter cotton 10, and both sides of the mounting block 22 are fixedly installed with the inside of the two filter boxes 5, fixedly connected and located at the bottom of the first filter cotton 10 and the top of the second filter cotton 11.

[0035] When the moving block 23 at the bottom of the second filter cotton 11 moves, the connecting plate 24 is driven to move, and the second electric push rod 27 drives the knocking plate 28 to move up and down. When the moving block 23 drives the connecting plate 24 to move back and forth on the top of the second filter cotton 11, the knocking plate 28 can knock and vibrate the second filter plate 12, thereby preventing oil impurities from remaining in the second filter plate 12, thereby improving the filtering effect of the second filter plate 12.

[0043] Since the first sealing plate 351 and the second sealing plate 353 are located between the connecting pipe 29 and the conveying pipe 31, the first sealing plate 351 and the second sealing plate 353 are connected through the action of the first magnetic block 352 and the second magnetic block 354, and the conveying pipe 31 is connected to the connecting pipe 29. The electric telescopic rod 355 is supported by the support plate. Through the second movable port on one side of the support plate, when the connecting block 356 moves, it is easy to drive the elastic telescopic tube 33 to expand and contract, so that the first magnetic block 352 and the second magnetic block 354 on one side of the first sealing plate 351 are separated, so that the first sealing block is separated from the second sealing block, and the conveying pipe 31 is driven to separate from the connecting pipe 29, so as to facilitate the movement of the first filter plate 9, the first filter cotton 10 and the second filter cotton 11.

[0044] Working principle: When in use, the oil mist generated in the CNC workshop is sucked into the air inlet 2 through the adsorption force formed by the wind motor inside the motor box 1, and enters the filter boxes 5 on the left and right sides through the ventilation device. The oil mist first passes through the high-pressure plate 7, and then passes through the low-pressure plate 8 to adsorb large particles in the oil mist, and then passes through the first filter cotton 10 and the second filter cotton 11 in the first filter plate 9 to filter and adsorb the oil. When the first filter cotton 10 is saturated with the second filter cotton 11 to adsorb the oil, the oil will fall and can be collected through the oil outlet 4, thereby realizing the recycling of the oil. The air adsorbed by the first filter cotton 10 and the second filter cotton 11 continues to go up, is filtered by the second filter plate 12, and continues to pass through the filter box 5 through the adsorption force formed by the fan 34. The third filter plate 13 on the upper layer filters, and the third filter cotton 14 and the fourth filter cotton 15 absorb impurities in the oil. When the third filter cotton 14 and the fourth filter cotton 15 are saturated with oil, the oil continues to fall and will be further recycled. At this time, the air continues to go up through the fan 34 and is discharged from the filter device through the air outlet 3 to be discharged from the workshop to prevent oil mist from polluting the processing workshop. After the third filter cotton 14 and the fourth filter cotton 15 are saturated with oil, the oil continues to fall and falls onto the first filter plate 9, so that the first filter cotton 10 and the second filter cotton 11 absorb oil again, so that the first filter cotton 10 and the second filter cotton 11 have residual oil, and the first electric push rod 25 drives the extrusion plate 26 to fit with the bottom of the first filter cotton 10, The top of the second filter cotton 11 is fitted, and then the first motor 16 is started to drive the first rotating rod 17 and the first transmission wheel 18 to rotate. Under the transmission action of the belt 19, the second transmission wheel 20 and the second rotating rod 21 are driven to rotate, so that the first rotating rod 17 and the second rotating rod 21 rotate at the same time to drive the moving block 23 to move in the mounting block 22. The moving block 23 drives the connecting plate 24 to move back and forth between the bottom of the first filter cotton 10 and the top of the second filter cotton 11, so that the squeezing plate 26 squeezes the first filter cotton 10 and the second filter cotton 11 to squeeze out the residual oil in the first filter cotton 10 and the second filter cotton 11. At the same time, when the moving block 23 above the second filter cotton 11 moves, it drives the second electric push rod 27 and the knocking plate 28 to move. 7 pushes the knocking plate 28 to move up and down to knock the second filter plate 12 to prevent the second filter plate 12 from accumulating oil. When the squeezing plate 26 squeezes the first filter cotton 10 and the second filter cotton 11, the self-priming pump 32 is started to absorb the oil inside the first filter cotton 10 and the second filter cotton 11 through the connecting pipe 29 and the collecting pipe 30. At the same time, the first filter cotton 10 and the second filter cotton 11 can be adsorbed on the first filter plate 9 to prevent deformation during squeezing. The oil is transported to the bottom of the filter box 5 through the delivery pipe 31 and the elastic telescopic pipe 33, and the oil is collected at the oil outlet 4, so that the residual oil in the first filter cotton 10 and the second filter cotton 11 is squeezed clean and adsorbed, thereby further improving the adsorption effect of the first filter plate 9, the first filter cotton 10 and the second filter cotton 11.

[0045] When the air filtration is completed, the electric telescopic rod 355 is started to drive the first sealing plate 351 to move downward, so that the first magnetic block 352 is separated from the second magnetic block 354, and the elastic telescopic tube 33 is contracted, thereby separating the delivery pipe 31 from the connecting pipe 29, and then the first filter plate 9 is moved, so that the first filter plate 9 moves inside the slide groove, and the connecting pipe 29 moves in the moving port, so that the first filter plate 9 drives the first filter cotton 10 and the second filter cotton 11 to move out of the filter box 5 for replacement, thereby further improving the adsorption effect of the first filter plate 9, the second filter cotton 11 and the second filter cotton 11.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
