[0002] After electrochemical microbial testing of different water qualities in the laboratory, a large amount of waste liquid will be generated. The various microorganisms in the waste liquid will multiply and breed many colonies, and these different water qualities themselves will contain a lot of impurities and pollutants.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention rapidly pours the waste liquid into the treatment barrel through the injection pipe. At this time, the float gradually rises with the increase of the waste liquid. During the rising process, the guide column is driven to move upward, thereby driving the drive device to move and storing energy in the drive device. When the impurities on the filter plate increase, the liquid flowing into the cone after filtration is reduced, and the energy in the drive device is released to drive the sleeve to rotate, thereby driving the scraper to scrape and push the impurities on the filter screen, and causing the impurities to flow into the upper liquid, so that the unfiltered liquid can be fully filtered, the filtration efficiency is improved, and time is saved.

[0015] 2. The present invention filters out liquid at a certain rate through the filter plate, and the filtered liquid impacts the baffle ring, and then the pressure ring is moved downward through the vertical cylinder and the connecting rod, and then the second spring is compressed to press the friction plate. At this time, the annular cylinder does not move. With the gradual deposition of impurities, the filter plate is gradually blocked seriously, resulting in a decrease in the outflow speed of the waste liquid and a decrease in the outflow amount, and then the impact force on the baffle ring is reduced. At this time, the compression amount of the second spring becomes smaller, and the pressure on the friction plate is reduced. Then, under the action of the first coil spring, the annular cylinder rotates, and then drives the upper mounting plate and the cone sleeve to rotate, and then drives the sleeve to rotate, so that the scraper rotates, so as to automatically disturb the waste liquid above the filter plate in the processing barrel, scrape and push up the impurities, so that the upper liquid can pass through the filter plate better, thereby improving the filtration efficiency and saving time.

DETAILED DESCRIPTION

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 6 The present invention provides a technical solution: a waste liquid treatment device for electrochemical microbial detection, comprising a treatment barrel 1, an end cap 2 is threadedly connected to the top of the treatment barrel 1, a liquid injection port 3 is connected to the end cap 2, a liquid outlet pipe 4 is connected to the bottom of the side wall of the treatment barrel 1, a filter plate 5 is fixed in the middle of the treatment barrel 1, the axis of the filter plate 5 coincides with the axis of the treatment barrel 1, a cone 6 is fixed at the bottom of the filter plate 5, an opening is provided at one end of the cone 6 away from the filter plate 5, the opening is circular, a sleeve 7 is rotatably connected to the middle of the filter plate 5, and the sleeve 7 extends to A plurality of scrapers 8 are fixed to the partial array above the filter plate 5. A driving device for driving the sleeve 7 to rotate is installed between the end of the sleeve 7 extending to the bottom of the filter plate 5 and the cone 6. A liner 9 is rotatably connected in the sleeve 7. A guide column 10 is slidably sleeved in the liner 9. The axis of the guide column 10 coincides with the axis of the filter plate 5. A floating ball 11 is fixed to the end of the guide column 10 extending above the filter plate 5. A counterweight 12 is fixed to the end of the guide column 10 extending below the filter plate 5. Two symmetrically distributed central weights are arranged on the guide column 10. The spiral protrusion 13 and the inner wall of the liner 9 are provided with a groove matched with the spiral protrusion 13. The driving device includes a cone sleeve 14 fixedly connected to the sleeve 7. An upper mounting plate 15 is fixed to the bottom of the cone sleeve 14. A lower mounting plate 16 fixedly connected to the inner wall of the cone cylinder 6 is arranged below the upper mounting plate 15. An annular cylinder 17 is fixed below the upper mounting plate 15. An annular groove is arranged outside the annular cylinder 17. A driving component is arranged inside the annular cylinder 17. A transmission component is connected to the annular groove. By quickly pouring the waste liquid into the treatment barrel 1 through the injection pipe, the float 11 gradually rises with the increase of the waste liquid. During the rising process, the guide column 10 is driven to move upward, thereby driving the driving device to move and storing energy in the driving device. When the impurities on the filter plate 5 increase, the liquid flowing into the cone cylinder 6 after filtration is reduced, and then the energy in the driving device is released to drive the sleeve 7 to rotate, thereby driving the scraper 8 to scrape and push the impurities on the filter screen, and make the impurities disturb the flow into the upper liquid, so that the unfiltered liquid can be fully filtered, the filtering efficiency is improved, and time is saved.

[0026] For details, please refer to Figure 2 , Figure 3 and Figure 6The driving component includes a transmission ring 18 arranged between the upper mounting plate 15 and the lower mounting plate 16. The upper and lower surfaces of the transmission ring 18 are provided with annular guide rails 19. A plurality of connecting columns 20 are slidably connected in the two annular guide rails 19. The plurality of connecting columns 20 are respectively fixedly connected to the upper mounting plate 15 and the lower mounting plate 16 on the corresponding sides. A first coil spring 21 is provided between the transmission ring 18 and the annular cylinder 17. The two ends of the first coil spring 21 are respectively fixedly connected to the transmission ring 18 and the annular cylinder 17. A first coil spring 21 is provided between the transmission ring 18 and the guide column 10. There is a driving assembly, and the guide column 10 passes through the filter plate 5, the sleeve 7, the cone cylinder 6, the upper mounting plate 15, the ratchet 22 and the lower mounting plate 16 from top to bottom, and the axis of the guide column 10 coincides with the axis of the vertical cylinder 28. During the upward movement of the guide column 10, the driving assembly drives the transmission ring 18 to rotate, thereby driving the first coil spring 21 to tighten and store energy, so that when the subsequent filter plate 5 is blocked, the energy is released, and the scraper 8 is rotated to scrape off the blocked impurities and mix them into the liquid above again, saving filtering time.

[0027] For details, please refer to Figure 2 , Figure 3 and Figure 6 The driving assembly includes a ratchet 22 rotatably sleeved on the outside of the guide column 10, and the inner wall of the transmission ring 18 is provided with a plurality of grooves, and a transmission block 23 is rotatably connected in each of the plurality of grooves. A first spring 24 is fixed on the transmission block 23, and one end of the first spring 24 away from the transmission block 23 is fixedly connected to the inner wall of the groove, and one end of the transmission block 23 away from the transmission ring 18 is in contact with the tooth surface of the ratchet 22.

[0028] In this solution, as the floating ball 11 on the guide column 10 rises with the liquid level, the spiral protrusion 13 drives the ratchet 22 to rotate, and the transmission block 23 drives the transmission ring 18 to rotate, thereby driving the first coil spring 21 to contract and store energy. When the floating ball 11 on the guide column 10 descends with the liquid level, the ratchet 22 rotates in the opposite direction, and the transmission ring 18 does not rotate at this time.

[0029] For details, please refer to Figure 3 , Figure 4 and Figure 5 The transmission component includes a pressure ring 25 which is slidably sleeved with the annular cylinder 17, a second spring 26 is connected to the outer shell of the annular cylinder 17, the upper end of the second spring 26 is in contact with the pressure ring 25, and the lower end of the second spring 26 is provided with a friction plate 27 which is rotatably sleeved with the annular cylinder 17. The pressure ring 25 and the friction plate 27 are both arranged in annular grooves on the annular cylinder 17, and a transmission assembly is installed on the pressure ring 25.

[0030] For details, please refer to Figure 5 and Figure 6The transmission assembly includes a vertical cylinder 28 located below the lower mounting plate 16, and a plurality of connecting rods 29 are fixedly connected between the vertical cylinder 28 and the pressure ring 25, wherein the guide column 10 can extend into the interior of the vertical cylinder 28 during the downward movement, and a retaining ring 30 is fixed to one end of the vertical cylinder 28 extending out of the cone cylinder 6, and the diameter of the retaining ring 30 is larger than the opening diameter of the cone cylinder 6, which can ensure that the filtered liquid flows out through the opening of the cone cylinder 6 and more fully impacts the retaining ring 30.

[0031] In addition, it should be noted that when the waste liquid passes through the filter plate 5 normally and can be filtered at a certain rate, the filtered liquid impacts the baffle ring 30, and then the pressure ring 25 is moved downward through the vertical cylinder 28 and the connecting rod 29, and then the second spring 26 is compressed to press the friction plate 27. At this time, the annular cylinder 17 does not move. As impurities gradually accumulate, the filter plate 5 is blocked more and more seriously, resulting in a decrease in the outflow speed and amount of waste liquid, and then the impact force on the baffle ring 30 is reduced. At this time, the compression amount of the second spring 26 becomes smaller, and the pressure of the friction plate 27 is reduced. Then, under the action of the first coil spring 21, the annular cylinder 17 rotates, and then drives the upper mounting plate 15 and the cone sleeve 14 to rotate, and then drives the sleeve 7 to rotate, so that the scraper 8 rotates, so as to automatically disturb the waste liquid above the filter plate 5 in the processing barrel 1, scrape and push up the impurities, so that the upper liquid can better pass through the filter plate 5, improve the filtration efficiency, and save time.

[0032] For details, please refer to Figure 5 and Figure 6 A second coil spring 31 is fixed below the ratchet 22, and one end of the second coil spring 31 away from the ratchet 22 is fixedly connected to the lower mounting plate 16. After the waste liquid is gradually filtered, and through the cooperation of the second coil spring 31 and the counterweight block 12, the process of the guide column 10 driving the float 11 to gradually move downward becomes smoother.
