[0018] Embodiment: As Figures 1-5As shown in the figure, the utility model provides a filter for a chemical workshop, which includes a filter housing 1. A filter cylinder 3 is fixedly arranged inside the filter housing 1. A water inlet pipe 5 is fixedly penetrated through the outside of the filter housing 1. One end of the water inlet pipe 5 is inserted into the filter cylinder 3. A water outlet pipe 6 is fixedly penetrated through the side of the filter housing 1 away from the water inlet pipe 5. A cleaning component 2 is arranged inside the filter housing 1, and a waste discharging component 4 is arranged inside the filter cylinder 3; the waste discharging component 4 includes a semi-circular plate 41. The two semi-circular plates 41 are mirror-symmetrically distributed. A first rotating shaft 42 is fixedly penetrated through the outside of the semi-circular plate 41. One end of the first rotating shaft 42 is rotatably installed on the inner wall of the filter cylinder 3. The other end of the first rotating shaft 42 extends out of the filter cylinder 3 through the outside of the filter cylinder 3 in an activity manner. A gear 43 is fixedly sleeved on one end of the first rotating shaft 42. The outside of the two gears 43 is meshed with each other. A connecting rod 44 is fixedly arranged at one end of one of the first rotating shafts 42. One end of the connecting rod 44 penetrates through the filter housing 1 in an activity manner. By rotating the connecting rod 44, the connecting rod 44 drives the first rotating shaft 42 to rotate. At the same time, the two first rotating shafts 42 rotate in opposite directions through the two gears 43. The first rotating shaft 42 drives the semi-circular plate 41 to rotate downward and open. The liquid in the filter cylinder 3 carries impurities and falls into the waste discharging hopper 7, and is discharged from the filter housing 1 through the waste discharging pipe 8. In this way, the situation that it is difficult to take out the impurities in the filter cylinder 3 can be avoided. A waste discharging hopper 7 is fixedly arranged at the bottom end of the filter cylinder 3. A waste discharging pipe 8 is fixedly arranged at the bottom end of the waste discharging hopper 7. One end of the waste discharging pipe 8 is fixedly penetrated through the filter housing 1. The waste discharging hopper 7 can guide the impurities, and the waste discharging pipe 8 can discharge the impurities from the filter housing 1. A square block 45 is sleeved on the end of the connecting rod 44 away from the filter housing 1 in an activity manner. A guiding groove 47 is opened on the inner side of the square block 45. A guiding rod 46 is fixedly arranged on the outside of the connecting rod 44. The guiding rod 46 is slidably clamped in the guiding groove 47. By clamping the square block 45 on the guiding rod 46 through the guiding groove 47, it is convenient to rotate the connecting rod 44. A sealing gasket 410 is fixedly arranged on the inner wall of the filter cylinder 3. The sealing gasket 410 is located between the two semi-circular plates 41. The sealing gasket 410 can improve the sealing performance between the two semi-circular plates 41. A square frame 48 is fixedly arranged on the outside of the filter housing 1. One end of the square block 45 is inserted into the square frame 48 in an activity manner. By clamping the square block 45 into the square frame 48, the square block 45 can be prevented from rotating. A limiting disc 49 is fixedly arranged at the end of the connecting rod 44 away from the filter cylinder 3. The limiting disc 49 can prevent the square block 45 from separating from the connecting rod 44. The semi-circular plate 41 is located below the scraping rod 23. In this way, the operation of the scraping rod 23 can be avoided from being affected.

[0019] The cleaning component 2 includes a second rotating shaft 21. One end of the second rotating shaft 21 is rotatably installed at the top inside the filter housing 1. An annular array of connecting plates 22 is fixedly arranged on the outer side of the second rotating shaft 21. A scraping rod 23 is fixedly arranged at one end of the connecting plate 22 away from the second rotating shaft 21. One side of the scraping rod 23 is attached to the inner wall of the filter cartridge 3. A motor 24 is fixedly arranged at the top end of the filter housing 1. The end of the output shaft of the motor 24 movably penetrates through the filter housing 1 and is fixedly connected to one end of the second rotating shaft 21. The end of the output shaft of the motor 24 drives the second rotating shaft 21 to rotate. The second rotating shaft 21 drives the connecting plate 22 to rotate. The connecting plate 22 drives the scraping rod 23 to rotate, so that the scraping rod 23 scrapes off the impurities adhering to the inner wall of the filter cartridge 3, which can avoid the accumulation of impurities on the filter cartridge 3 and affect the filtration efficiency.

[0020] Working principle: First, the liquid enters the filter cartridge 3 inside the filter housing 1 from the water inlet pipe 5. The liquid passes through the filter cartridge 3 and its impurities are filtered, and then falls into the filter housing 1 and is discharged from the water outlet pipe 6. Then, the motor 24 is started to make the motor 24 start to work. The end of the output shaft of the motor 24 drives the second rotating shaft 21 to rotate. The second rotating shaft 21 drives the connecting plate 22 to rotate. The connecting plate 22 drives the scraping rod 23 to rotate, so that the scraping rod 23 scrapes off the impurities adhering to the inner wall of the filter cartridge 3, which can avoid the accumulation of impurities on the filter cartridge 3 and affect the filtration efficiency, thus achieving the purpose of convenient cleaning.

[0021] When it is necessary to discharge the impurities in the filter cartridge 3, first move the square block 45 out of the square frame 48, and then rotate the square block 45. The square block 45 drives the connecting rod 44 to rotate through the guide rod 46. The connecting rod 44 drives the first rotating shaft 42 to rotate. At the same time, the two first rotating shafts 42 rotate in opposite directions through the two gears 43. The first rotating shaft 42 drives the semi-circular plate 41 to rotate downward and open. The liquid in the filter cartridge 3 carries impurities and falls into the waste discharge hopper 7 and is discharged from the waste discharge pipe 8 out of the filter housing 1, which can avoid the situation that the impurities in the filter cartridge 3 are difficult to take out, thus achieving the purpose of convenient discharge. Finally, reverse the square block 45 to close the semi-circular plate 41, and move the square block 45 to be stuck into the square frame 48.

[0022] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
