Simultaneously, through the action of a linear guide rail, sliding sleeve, and connecting plate, the control switch activates the linear guide rail, which in turn moves the sliding sleeve, connecting plate, connecting rod, and retrieval frame. This allows the retrieval frame to... Impurities at different distances are retrieved, and corrugated rubber tubes are installed on the linear guide rail for dust and water protection. The stepper motor is also dustproof and waterproof, ensuring normal operation in various environments and improving the overall practicality and flexibility of the device. The stepper motor is started by a control switch, causing its output to drive the rotating disk. The angle of retrieval is adjusted by the rotation of the rotating disk.

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.

[0017] Please see Figure 1-5 This utility model provides a technical solution: a device for removing impurities in sewage treatment, including a base 1, with casters 2 fixedly installed around the bottom surface of the base 1; a counterweight 3 is fixedly connected to one side of the top surface of the base 1, and a rotating groove 6 is formed on the other side of the top surface of the base 1, with a fixing block 7 fixedly connected in the middle of the rotating groove 6; it also includes: a removal component 4 disposed on the top surface of the fixing block 7; wherein, the removal component 4 includes a motor housing 401 fixedly connected to the fixing block 7; wherein, a stepper motor 402 is fixedly installed inside the motor housing 401, such as Figure 1-5 As shown, by setting the retrieval component 4, the retrieval frame 5 can be moved up and down and back and forth, thereby increasing the retrieval range to a certain extent and improving the overall flexibility and practicality of the device. At the same time, the cooperation between the connecting sleeve 8, the threaded rod 9 and the nut 10 makes it easier to disassemble and install the retrieval frame 5.

[0018] A rotating disk 403 is fixedly connected to one side of the output end of the stepper motor 402, passing through the motor housing 401. A hydraulic telescopic rod 404 is fixedly connected to the middle of the top surface of the rotating disk 403. A stabilizing plate 405 is fixedly connected to the top surface of the hydraulic telescopic rod 404. Grooves 406 are symmetrically formed on one side surface of the stabilizing plate 405. Several support rods 407 are fixedly connected to the bottom surface of the rotating disk 403. A linear guide rail 408 is fixedly installed inside the groove 406. A sliding sleeve 409 is connected through the surface of the linear guide rail 408. A connecting plate 410 is fixedly connected to the bottom surface of the sliding sleeve 409. The connecting plate 410 is in close contact with the stabilizing plate 405. Several connecting rods 411 are fixedly connected to both sides of the bottom surface of the connecting plate 410. A retrieval frame 5 is fixedly installed on the bottom surface of the connecting rods 411. Figure 2 , 3 As shown, when retrieving large impurities from sewage, a control switch activates the hydraulic telescopic rod 404, causing its output end to rise and fall. This rise and fall of the hydraulic telescopic rod 404, in turn, causes the stabilizing plate 405 to rise and fall. The stabilizing plate 405, in turn, causes the connecting rod 411 and the retrieval frame 5 to rise and fall, thus adapting to water depths. Simultaneously, through the action of the linear guide rail 408, sliding sleeve 409, and connecting plate 410, the control switch activates the linear guide rail 408, causing it to move the sliding sleeve 409, connecting plate 410, connecting rod 411, and retrieval frame 5, thereby allowing the retrieval frame 5 to... This device is designed to retrieve impurities at varying distances. A corrugated rubber tube is installed on the linear guide 408 for dust and water protection. The stepper motor 402 is also dust and water resistant, ensuring normal operation in different environments and improving the overall practicality and flexibility of the device. Starting the stepper motor 402 via a control switch causes its output to rotate the rotating disk 403. The rotation of the disk adjusts the retrieval angle. Simultaneously, the rotation of the disk causes the support rod 407 to slide adaptively within the rotating groove 6, providing auxiliary support to the disk 403. The stepper motor 402 (model NEMA17) is electrically connected to the control switch and is dust and water resistant. Similarly, the linear guide 408 (model SHW35CA1UU) is also dust and water resistant and electrically connected to the control switch.

[0019] Several connecting sleeves 8 are symmetrically installed on the top surface of the retrieval frame 5. A threaded rod 9 is threaded through the center of the surface of the connecting sleeve 8. Nuts 10 are threaded on both sides of the surface of the threaded rod 9. The connecting sleeve 8 is sleeved and connected to the connecting rod 411. The threaded rod 9 is threaded through the connecting rod 411. The rotating groove 6 is slidably connected to the support rod 407. Figure 5 As shown, by setting up the connecting sleeve 8, the threaded rod 9 and the nut 10, when assembling the salvage frame 5, the connecting rod 411 is sleeved on the connecting sleeve 8, and then the threaded rod 9 passes through the connecting rod 411 and the connecting sleeve 8. The nut 10 is then threaded onto both sides of the threaded rod 9 using a tool, thereby completing the assembly of the salvage frame 5. At the same time, the threaded rod 9 and the nut 10 are made of stainless steel, which gives them good corrosion and rust resistance.

[0020] Working principle: Before using this impurity removal equipment for sewage treatment, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5 As shown, firstly, by setting up a retrieval device, when retrieving large impurities from sewage, a control switch is used to activate the hydraulic telescopic rod 404, causing its output end to rise and fall. This rise and fall of the hydraulic telescopic rod 404's output end drives the stabilizing plate 405 to rise and fall. The rise and fall of the stabilizing plate 405, in turn, drives the connecting rod 411 and the retrieval frame 5 to rise and fall, thus adapting to water depths of varying sizes. Simultaneously, through the action of the linear guide rail 408, the sliding sleeve 409, and the connecting plate 410, the control switch activates the linear guide rail 408, causing it to move the sliding sleeve 409, the connecting plate 410, the connecting rod 411, and the retrieval frame 5, thereby... The retrieval frame 5 can retrieve impurities at different distances. Corrugated rubber tubing is installed on the linear guide 408 for dust and water protection. The stepper motor 402 is also dustproof and waterproof, ensuring normal operation in various environments and improving the overall practicality and flexibility of the device. The stepper motor 402 is activated by a control switch, causing its output to rotate the rotating disk 403. This rotation adjusts the retrieval angle. Simultaneously, the rotation of the rotating disk 403 causes the support rod 407 to slide adaptively within the rotating groove 6, providing additional support to the rotating disk 403.

[0021] Secondly, by setting up the connecting sleeve 8, the threaded rod 9, and the nut 10, when assembling the retrieval frame 5, the connecting rod 411 is sleeved on the connecting sleeve 8, and then the threaded rod 9 passes through the connecting rod 411 and the connecting sleeve 8. The nut 10 is then threaded onto both sides of the threaded rod 9 using a tool, thereby completing the assembly of the retrieval frame 5. At the same time, the threaded rod 9 and the nut 10 are made of stainless steel, which gives them good corrosion and rust resistance.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
