Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This utility model discloses a filter for treating industrial wastewater, including a housing 1 and a filter basket 2 disposed inside the housing 1 for treating industrial wastewater. It also includes: a cleaning box 3 disposed inside the filter basket 2, the cleaning box 3 being used to clean impurities on the filter basket 2; a drive device inside the housing 1 for driving the longitudinal movement of the cleaning box 3, and a rotating device on the surface of the longitudinal drive device for driving the cleaning box 3 to rotate; a scraper pipe 4 fixedly connected to the feed inlet on one side of the cleaning box 3, the scraper pipe 4 having a pushing device inside for propelling impurities into the cleaning box 3; and a storage box 5 inserted into the other side of the cleaning box 3, the storage box 5 being used to process collected impurities, and a locking device on the surface of the cleaning box 3 for fixing the storage box 5.

[0023] Specifically, the drive device includes a drive motor 6, a lead screw 7, and a slider 8. The drive motor 6 is mounted on the top of the housing 1 via a bracket. One end of the lead screw 7 is fixedly connected to the output shaft of the drive motor 6, and the other end of the lead screw 7 is connected to the filter basket 2 via a bearing. Guide rods are provided on both sides of the lead screw 7. The slider 8 is sleeved on the surface of the lead screw 7 and the guide rods, and the slider 8 is threadedly connected to the lead screw 7.

[0024] In this embodiment, the drive motor 6 is controlled to drive the output shaft of the drive motor 6 to drive the lead screw 7 to rotate. The lead screw 7 drives the slider 8 to move downward along the guide rod through the thread. At the same time, the slider 8 drives the cleaning box 3 to contact the filter basket 2 through the bearing seat 9, and then cleans the filter basket 2. The top of the housing 1 has an outlet. When it is necessary to process the impurities stored in the storage box 5, the output shaft of the drive motor 6 is controlled to reverse, driving the cleaning box 3 to move to the outside of the housing 1 through the outlet, so as to facilitate the removal and cleaning of the storage box 5.

[0025] Specifically, the rotating device includes a bearing housing 9, a rotating motor 10, a rotating gear 11, and a fixed gear ring 12. One side of the bearing housing 9 is fixedly connected to the surface of the cleaning box 3, and the bearing housing 9 is fixedly sleeved on the surface of the slider 8. The rotating motor 10 is set on the top surface of the cleaning box 3 through a connecting frame. The rotating gear 11 is fixedly connected to the output shaft of the rotating motor 10, and the fixed gear ring 12 is fixedly connected to the slider 8. The rotating gear 11 meshes with the fixed gear ring 12.

[0026] In this embodiment, the control motor 10 is started, and the output shaft of the motor 10 drives the rotating gear 11 to rotate, so that the rotating gear 11 rotates around the fixed gear ring 12. At the same time, the cleaning box 3 rotates around the slider 8 under the action of the bearing seat 9. When the cleaning box 3 rotates, it removes the impurities in the filter basket 2 into the shovel tube 4 through the shovel tube 4.

[0027] Specifically, the actuating device includes a brush roller 13, two transmission gears 14, and a fixed motor 15. The brush roller 13 is set at the internal opening of the shovel tube 4 through a central shaft. The fixed motor 15 is fixedly set on the surface of the shovel tube 4. The two transmission gears 14 are respectively fixedly sleeved on the output shaft of the fixed motor 15 and the surface of the central shaft of the brush roller 13, and the two transmission gears 14 mesh.

[0028] In this embodiment, impurities in the filter basket 2 are shoveled into the shovel tube 4, and at the same time, the fixed motor 15 is started. The fixed motor 15 drives the brush roller 13 to rotate through two transmission gears 14. The brush roller 13 sweeps the impurities that have entered the shovel tube 4 into the cleaning box 3, and then stores them in the storage box 5, thereby achieving automatic cleaning of the filter basket 2.

[0029] Specifically, a cover 16 is fixedly installed on the surface of the shovel tube 4, and both transmission gears 14 are installed inside the cover 16. The cover 16 is used to protect the transmission gears 14.

[0030] In this embodiment, the transmission gear 14 is protected by a cover 16 to prevent impurities from adhering to the transmission gear 14 and jamming it.

[0031] Specifically, the locking device includes a rod 17, a fixed seat 18, and a return spring 19. The fixed seat 18 is fixedly installed on the surface of the cleaning box 3. One end of the rod 17 passes through the fixed seat 18 and is connected to the surface of the storage box 5. The return spring 19 is sleeved on the rod 17, and both ends of the return spring 19 are fixedly connected to the rod 17 and the fixed seat 18, respectively.

[0032] In this embodiment, the insertion rod 17 is pulled upward so that it moves along the fixed base 18 until it is disengaged from the storage box 5. At the same time, the return spring 19 is stretched elastically. Then, the storage box 5 is pulled out from the cleaning box 3 to process the impurities stored in the storage box 5.

[0033] Specifically, the top of the cleaning box 3 is equipped with an electric push rod 20, and the inside of the cleaning box 3 is equipped with a pressure plate 21. The telescopic shaft of the electric push rod 20 passes through the cleaning box 3 and is fixedly connected to the pressure plate 21.

[0034] In this embodiment, when impurities enter the storage box 5, the telescopic shaft of the electric push rod 20 is extended, and the telescopic shaft drives the pressure plate 21 to press down, thereby compacting the impurities in the storage box 5 and increasing the storage capacity of the storage box 5.

[0035] The working principle and usage process of this utility model are as follows: During use, industrial wastewater is added into the housing 1 through the inlet at the top of the housing 1. The wastewater then passes through the filter basket 2 and flows out from the outlet at the bottom of the housing 1. As it passes through the filter basket 2, impurities in the wastewater are filtered out. After prolonged filtration, impurities remain on the filter basket 2, causing blockage. To clean the impurities in the filter basket 2, the drive motor 6 is activated. The output shaft of the drive motor 6 drives the lead screw 7 to rotate. The lead screw 7, through a thread, drives the slider 8 to move downwards along the guide rod. Simultaneously, the slider 8, through the bearing seat 9, drives the cleaning box 3 to move downwards. When the filter basket 2 comes into contact, the control motor 10 starts. The output shaft of the control motor 10 drives the rotating gear 11 to rotate, causing the rotating gear 11 to rotate around the fixed gear ring 12. At the same time, the cleaning box 3 rotates around the slider 8 under the action of the bearing seat 9. When the cleaning box 3 rotates, it removes the impurities in the filter basket 2 into the shovel tube 4 through the shovel tube 4. At the same time, the control motor 15 starts. The fixed motor 15 drives the brush roller 13 to rotate through two transmission gears 14. The brush roller 13 sweeps the impurities that have entered the shovel tube 4 into the cleaning box 3 and then stores them in the storage box 5, thus achieving automatic cleaning of the filter basket 2.
