Wastewater is treated by wastewater treatment equipment and then reused. In the process of purifying wastewater, there is a filtration step. Traditional filtration equipment is a multi-layer filter net. After the filter net has been filtered for a period of time, the blocked impurities will adhere to the vicinity of the filter net, affecting the filtration rate. Faced with this situation, the staff usually cleans the filter net regularly, and the use of the filtration equipment has to be stopped during the cleaning process, and the manpower is increased. The existing filtration equipment cannot automatically clean the filter net during use. In view of the above problems, a filtration equipment for wastewater purification is proposed. Utility Model Content

[0004] A filtering device for wastewater purification comprises a pipe body, characterized in that: a rotatable filter cartridge is arranged inside the pipe body, a scraping mechanism for scraping dust is arranged on the inner wall of the pipe body, the scraping mechanism comprises a mounting frame and a movable frame, the mounting frame is integrally arranged on the inner wall of the pipe body, a notch is provided on the surface of the mounting frame, the movable frame is overlapped on the surface of the notch, an annular groove is provided on the outer surface of the filter cartridge, the movable frame is overlapped on the surface of the annular groove, an automatic dust discharge mechanism is arranged at the bottom of the pipe body, the automatic dust discharge mechanism comprises an dust discharge frame, a translation frame and a sealing frame, the dust discharge frame is slidably arranged at the bottom of the pipe body, and a No. 1 spring is arranged between the dust discharge frame and the pipe body.

[0005] The above technical solution has the following beneficial effects:

[0006] The present solution can achieve the effect of rotational position adjustment by setting a rotatable filter cartridge, and can contact the scraper during the rotation process, so that the scraper scrapes off the dust on the surface of the filter cartridge. The rotation of the filter cartridge can also cause the movable frame to move up and down, so that the brush on one side of the movable frame can clean the surface of the filter cartridge. When the filter cartridge rotates, the translation frame will also move downward, so that the dust on the surface of the scraper can be removed and reach the bottom of the track, so that the bottom of the tube body can be sealed, and the ash discharge frame can be squeezed for automatic ash discharge.

DETAILED DESCRIPTION

[0013] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figures 1 to 5 The embodiments are described in detail.

[0014] This embodiment provides a filtration device for wastewater purification, the specification is attached Figure 1 The overall structure diagram of this scheme shows that the filter cartridge 2 is rotatably arranged inside the tube body 1. Figure 2 This is the main view of this scheme, the instruction manual is attached Figure 3 Attached to the instruction manual Figure 2 The present invention is described below. The driving source of the present invention relies on the motor 16. The motor 16 belongs to the prior art and is not described in detail. A driving rod 15 is installed below the motor 16. Therefore, the motor 16 can drive the driving rod 15 to rotate. The driving rod 15 can drive two sets of mechanisms to operate at the same time. A gear is arranged on the top of the driving rod 15. Figure 1As shown, the top of the filter cartridge 2 is also integrally provided with a ring that matches the gear, so the rotation of the drive rod 15 can drive the filter cartridge 2 to rotate, and the lower part of the drive rod 15 is a long screw, and the surface of the long screw is provided with a thread (the thread is not shown for the convenience of viewing, and there are matching screw holes on the translation frame 8, so the translation frame 8 will move downward when the drive rod 15 rotates, and the translation frame 8 is limited to slide inside the tube body 1), and the rotation of the drive rod 15 can simultaneously drive the translation frame 8 and the filter cartridge 2 to rotate, and the rotation of the filter cartridge 2 can make the outer surface of the filter cartridge 2 scrape off dust. Because the mounting frame 3 is arranged inside the tube body 1 and its position does not change, it can be understood as being integrally arranged inside the tube body 1 (see the instruction manual). Figure 5 The tube body is hidden, but the mounting frame 3 is not hidden. Scrapers 11 are arranged on both sides of the mounting frame 3. The scrapers 11 contact the filter cartridge 2 to scrape off the dust on the surface of the filter cartridge 2. The rotation of the filter cartridge 2 can also drive the movable frame 4 to move back and forth. The movable frame 4 slides and is limited on the notch 5, and the outer surface of the filter cartridge 2 is provided with an annular groove 6. The annular groove 6 has a height difference, so the rotation of the filter cartridge 2 can drive the movable frame 4 to move up and down. A brush 12 is installed on one side of the movable frame 4. The up and down movement of the brush 12 is equivalent to cleaning the dust on the surface of the filter cartridge 2. An air intake channel 13 is also arranged inside the movable frame 4. An air supply pipe 14 is connected to the top of the air intake channel 13. The air supply pipe 14 is a hose. The air supply pipe 14 can be connected to the aeration equipment to increase the aeration inside the tube body 1. The bottom of the filter cartridge 2 needs to be connected to the pipeline of the next step, but This pipe needs to be connected to the bottom of the filter cartridge 2 with a seal and rotation to isolate the bottom of the tube body 1. Finally, the translation frame 8 of this scheme is introduced. The dust on the scraper 11 can be scraped off during the downward movement of the translation frame 8, and the dust accumulated at the bottom of the tube body 1 can be automatically removed during the downward movement. The downward movement of the translation frame 8 will cause the sealing frame 9 to contact the inclined surface of the tube body 1 for sealing. At this time, the bottom of the tube body 1 and the top of the tube body 1 are isolated. As the translation frame 8 continues to move downward, the sealing plate does not move and slides along the surface of the sealing plate, so that the No. 2 spring 18 is squeezed, and there is a cylinder under the translation plate. The cylinder moves downward against the ash discharge frame 7, and the ash discharge frame 7 will reach the outside of the tube body 1 for ash discharge, and the sealing frame 9 is sealed on the inner inclined surface of the tube body 1 (the outer diameter of the sealing frame 9 is larger than the outer diameter of the ash discharge frame 7, as shown in the attached manual). Figure 3When the outer diameter of the dust discharge frame 7 corresponds to the bottom of the tube body 1 for sealing), the driving rod 15 is then driven to rotate in the opposite direction, and the mechanism of the present invention is reset. In the drawings of the specification, the No. 1 spring 10 and the No. 2 spring 18 are both in their original lengths. A rotatable filter cartridge 2 is provided inside the tube body 1 (the surface of the filter cartridge 2 has apertures or is an annular net), and a dust scraping mechanism for scraping dust is provided on the inner side wall of the tube body 1. The dust scraping mechanism includes a mounting frame 3 and a movable frame 4 (the movable frame 4 and the tube body 1 are also sealed and slidable, and corresponding sealing is provided). The sealing gasket is sufficient. There are many sealing mechanisms in this scheme. The sealing problem can be solved by setting corresponding sealing gaskets. An ash hopper for storing ash is set below the tube body 1. The mounting frame 3 is integrally arranged on the inner wall of the tube body 1. A notch 5 is opened on the surface of the mounting frame 3. The surface of the notch 5 is overlapped with a movable frame 4. An annular groove 6 is opened on the outer surface of the filter cartridge 2. The surface of the annular groove 6 is overlapped with the movable frame 4. An automatic ash discharge mechanism is set at the bottom of the tube body 1. The automatic ash discharge mechanism includes an ash discharge frame 7, a translation frame 8 and a sealing frame 9. The ash discharge frame 7 is slidingly arranged. The ash discharging frame 7 is placed at the bottom of the tube body 1, and a spring 10 is arranged between the ash discharging frame 7 and the tube body 1. Scrapers 11 are arranged on both sides of the mounting frame 3, and a brush 12 is arranged on one side of the movable frame 4. An air inlet channel 13 is arranged inside the movable frame 4, and an air supply pipe 14 is slidably arranged on the upper surface of the air inlet channel 13. A driving mechanism is arranged on the upper surface of the tube body 1, and the driving mechanism includes a driving rod 15 and a motor 16.
