[0002] Wastewater recycling filtration is a process that uses physical, chemical, or biological methods to purify and reuse wastewater. Its core principle is to use processes such as filtration, sedimentation, and chemical reactions to remove impurities, pollutants, and harmful substances from wastewater, so that the water quality meets discharge standards or reuse requirements. At the same time, the recycling mechanism improves treatment efficiency and resource utilization, which is of great significance in terms of environmental protection, resource conservation, and economic benefits.
[0003] However, most current wastewater recycling filtration devices have a primary large-particle filtration structure that easily accumulates a lot of debris, causing the filtration structure to become clogged and reducing the filtration effect.
[0004] Therefore, we provide a wastewater circulation filtration device to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. The drive motor provides power to rotate the first rotating shaft, which in turn drives the first gear to rotate the gear ring inside the support frame. The scraper contacts the surface of the filter screen barrel and rotates with it, scraping off large particles of impurities from the outer surface of the filter screen barrel. Each time the scraper passes through the groove at the bottom of the receiving barrel, the impurities fall into the collection box due to gravity. One side of the collection box is inserted into the reaction chamber. Residual moisture enters the reaction chamber through the filter screen plate, while the impurities are retained. The electric telescopic rod extends and retracts, causing the sliding bracket to move horizontally on the support plate, making the collection box easy to replace.
[0014] 2. Chemical agents are added to the reaction chamber to react with the water. The first rotating shaft drives the second gear to rotate, which in turn drives the third gear to rotate. This causes the second rotating shaft to drive the stirring blades to rotate and stir within the reaction chamber, enhancing the reaction effect between the water and the chemical agents. The first pump transfers the water through a pipeline to a sedimentation tank for sedimentation. The guide slope guides the sediment to the bottom and discharges it through the first control valve. The water is then pumped by the second pump through a pipeline to a filter tank. The multi-stage filter plate structure filters the water. The third pump circulates the filtered water through a pipeline to enhance the filtration effect. Attached Figure Description

[0021] Please see Figure 1-4 As shown, a wastewater circulation filtration device includes a reaction chamber 1 and a filter assembly 2. The filter assembly 2 is installed at the top of the reaction chamber 1. The filter assembly 2 includes a receiving bucket 201 fixedly connected to the top of the reaction chamber 1. A filter screen bucket 202 is installed inside the receiving bucket 201. A support frame 203 is fixedly connected to the top of the filter screen bucket 202. A toothed ring 204 is rotatably connected to the inner side of the support frame 203 through a slot. A scraper 205 is fixedly connected to the inner side of the toothed ring 204. Water is introduced into the receiving bucket 201 through the inlet at the top of the support frame 203, and then filtered through the filter screen bucket 202 before entering the reaction chamber 1. The scraper 205 contacts the surface of the filter screen bucket 202 and rotates with the toothed ring 204 to scrape off large particulate impurities from the outer surface of the filter screen bucket 202.
[0022] Furthermore, a first gear 206 is meshed with one side of the gear ring 204, and a first rotating shaft 207 is fixedly connected to the inner side of the first gear 206. A drive motor 208 is connected to the top of the first rotating shaft 207 via a flat key. The drive motor 208 provides power to drive the first rotating shaft 207 to rotate, so that the first gear 206 drives the gear ring 204 to rotate within the support frame 203.
[0023] Furthermore, a second gear 209 is fixedly connected to the bottom end of the first rotating shaft 207. A toothed belt 210 is meshed with the outer side of the second gear 209. A third gear 211 is meshed with the other side of the toothed belt 210. A second rotating shaft 212 is fixedly connected to the inner side of the third gear 211. A stirring blade 213 is fixedly connected to the surface of the second rotating shaft 212. Chemical agents are added into the reaction chamber 1 to react with the water. The first rotating shaft 207 drives the second gear 209 to rotate, which causes the toothed belt 210 to drive the third gear 211 to rotate. This causes the second rotating shaft 212 to drive the stirring blade 213 to rotate and stir within the reaction chamber 1, thereby enhancing the reaction effect between the water and the chemical agents.
[0024] Furthermore, a support plate 214 is fixedly connected to one side of the reaction chamber 1. A sliding bracket 215 is slidably connected to the top of the support plate 214 through a slot. An electric telescopic rod 216 is installed on one side of the sliding bracket 215. A collection box 217 is inserted into the inner side of the sliding bracket 215 through a slot. A filter screen 218 is installed on one side of the collection box 217. Impurities fall into the collection box 217 under gravity. One side of the collection box 217 is inserted into the reaction chamber 1. Residual moisture enters the reaction chamber 1 through the filter screen 218. Impurities are retained. The electric telescopic rod 216 extends and retracts, causing the sliding bracket 215 to move horizontally on the support plate 214, making the collection box 217 easy to replace.
[0025] Furthermore, a first pump 3 is installed on the upper surface of the reaction tank 1, and a sedimentation tank 4 is fixedly connected to the other side of the reaction tank 1. A guide slope 5 is fixedly connected to the bottom of the sedimentation tank 4, and a first control valve 6 is installed on one side of the bottom of the sedimentation tank 4. The first pump 3 transfers water to the sedimentation tank 4 through a pipeline for sedimentation, and the guide slope 5 guides the sediment to the bottom and discharges it through the first control valve 6.
[0026] Furthermore, a filter tank 7 is fixedly connected to the other side of the sedimentation tank 4. A second pump 8 is installed on one side of the top of the filter tank 7, and a third pump 9 is installed on the other side of the top of the filter tank 7. Filter plates 10 are inserted into the inner side of the filter tank 7 through slots. A second control valve 11 is installed on one side of the bottom of the filter tank 7. The water is then guided to the filter tank 7 by the second pump 8 through a pipeline. The multi-stage filter plate 10 structure filters the water. The filter plates 10 can be quickly replaced by insertion, and different materials of filter plates 10 can be set according to specific needs. The third pump 9 circulates the filtered water through a pipeline to enhance the filtration effect, and finally the purified water is discharged by the second control valve 11.
[0027] Working principle: In operation, firstly, water is introduced into the receiving bucket 201 through the inlet at the top of the support frame 203, then filtered through the filter screen 202 before entering the reaction chamber 1. The drive motor 208 provides power to rotate the first rotating shaft 207, causing the first gear 206 to drive the gear ring 204 to rotate within the support frame 203. The scraper 205 contacts the surface of the filter screen 202 and rotates accordingly, scraping away large particles of impurities from the outer surface of the filter screen 202. Each time the water passes through the slot at the bottom of the receiving bucket 201, impurities fall into the collection box 217 due to gravity. Secondly, one side of the collection box 217 is inserted into the reaction chamber 1. Residual water enters the reaction chamber 1 through the filter screen plate 218, while impurities are retained. The electric telescopic rod 216 extends and retracts, causing the sliding bracket 215 to move horizontally on the support plate 214, thus collecting the impurities. The collection box 217 is easy to replace. In the third step, chemical agents are added to the reaction chamber 1 to react with the water. The first rotating shaft 207 drives the second gear 209 to rotate, which in turn drives the toothed belt 210 to drive the third gear 211 to rotate. This causes the second rotating shaft 212 to drive the stirring blade 213 to rotate and stir in the reaction chamber 1, enhancing the reaction effect between the water and the chemical agents. In the fourth step, the first pump 3 transfers the water through the pipeline to the sedimentation tank 4 for sedimentation. The guide slope 5 guides the sediment to the bottom and discharges it through the first control valve 6. The water is then guided by the second pump 8 through the pipeline to the filter tank 7. The multi-stage filter plate 10 filters the water. The third pump 9 circulates the filtered water through the pipeline to enhance the filtration effect. The second control valve 11 discharges the purified water, thus completing the use of a wastewater circulation filtration device.
