DETAILED DESCRIPTION
[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model more clear, the technical scheme in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and the following embodiments are used to illustrate the utility model.
[0023] As Figures 1 to 5 shown, the sewage source heat pump sewage pretreatment device includes filter box 1 and filter grid 5, the inside of filter box 1 is provided with containing groove, the containing groove is provided with scraping mechanism, the scraping mechanism includes scraper 8 and first gear 20, the upper end of scraper 8 is provided with tooth slot 9 on one side, and the upper end of scraper 8 is fixedly connected with push rod 11, the upper end of first gear 20 is fixedly connected with transmission shaft 19, the upper end of transmission shaft 19 is fixedly connected with second gear 10, second gear 10 corresponds with tooth slot 9 and is intermeshed with tooth slot 9.
[0024] In the present setting, the utility model drives the cleaning mechanism to clean the impurities on the surface of the grid by using the pushing force generated by the dirt blocking the pipeline, simultaneously drives valve 17 to open the blow-off passage, discharges the blockage, and finally resets by the elastic force of spring 21 and the impact force of water flow on valve 17 combined with the eccentric shaft of valve 17.
[0025] As Figures 1 to 5As shown, in a specific embodiment, a scraper box 2 is fixedly connected to one side of the filter box 1. The scraper box 2 has an internal receiving groove, which corresponds to and is movably connected to the scraper 8. The filter box 1 also has an inlet 4 and a sliding groove 6, which corresponds to and is slidably connected to the scraper 8. A damping spring block 22 is fixedly connected inside the inlet 4. A water outlet pipe connector 12 is fixedly connected to one end of the filter box 1. A grid groove 14 is opened on the inner side of the water outlet pipe connector 12. A sliding rod and a rack groove are opened inside the water outlet pipe connector 12. A sliding rod 13 is movably connected inside the sliding rod groove. A spring 21 is installed between the sliding rod 13 and the sliding rod groove.
[0026] In this setup, when the equipment is working, if too much garbage accumulates on the filter grid 5, it will generate a large pressure inside the pipe. This pressure will apply pressure to the filter grid 5. When the filter grid is pushed away from the damping spring block 22, the instantaneous impact force generated will drive the first gear 20 to rotate through the rack 18.
[0027] like Figures 1 to 5 As shown, in a specific embodiment, a rack 18 is movably sleeved inside the rack groove. The rack 18 corresponds to and meshes with the first gear 20. One end of the slide rod 13 and the rack 18 corresponds to the inner side of the outer periphery of the filter grid 5 and is fixedly connected to it. The filter grid 5 corresponds to the grid groove 14 and the damping spring block 22.
[0028] In this configuration, the first gear 20 drives the second gear 10 to rotate via the transmission shaft 19. The second gear 10, through its meshing relationship with the tooth groove 9, drives the scraper 8 to slide towards the filter grid 5, cleaning the garbage on the surface of the filter grid 5 during the process.
[0029] like Figures 1 to 5 As shown, in a specific embodiment, a drain port 7 is provided inside the other side of the filter box 1. A drain pipe 3 is fixedly connected inside the drain port 7. A valve 17 is installed inside the drain pipe 3. The shaft at the lower end of the valve 17 is movably connected to the inner wall of the drain pipe 3. A connecting rod 16 is fixedly connected to the upper end of the valve 17. The connecting rod 16 passes through the top of the drain pipe 3 and is movably connected to it. A push plate 15 is fixedly connected to the top of the connecting rod 16. The push plate 15 corresponds to the push rod 11.
[0030] In this setup, when the filter screen 5 reaches a certain position, the upper push rod 11 strikes the push plate 15 and deflects, and drives the valve 17 to open via the connecting rod 16, discharging the waste. Then, the spring force of the spring 21 and the eccentric shaft of the valve 17, combined with the impact force of the water flow on the valve 17, perform a reset action.
[0031] The sewage source heat pump sewage pretreatment device of the embodiment has the following implementation principle:
[0032] The impurities on the surface of the grid are cleaned by the cleaning mechanism driven by the thrust generated by the dirt blocking the pipeline, and the valve 17 is opened to discharge the blockage.
[0033] When the filter grid 5 is accumulated with too much garbage, the device generates a large pressure in the pipeline, which exerts pressure on the filter grid 5. When the filter grid is pushed away from the damping spring block 22 and utilizes the instantaneous impact force generated, the first gear 20 is driven to rotate by the rack 18, the second gear 10 is driven to rotate by the transmission shaft 19, the scraper 8 is driven to slide to the filter grid 5 by the meshing relationship between the second gear 10 and the gear slot 9, and the garbage on the surface of the filter grid 5 is cleaned in the process. When the filter grid 5 reaches a certain position, the upper end of the push rod 11 hits the push plate 15 to be offset, and the valve 17 is opened by the connecting rod 16 to discharge the garbage, and then the spring 21 and the eccentric shaft of the valve 17 are combined with the impact force of the water flow on the valve 17 to perform a reset action.
