[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, as the amount of deposits on the outer wall of the filter cartridge increases, the filtration speed of the filter cartridge gradually decreases, and the wastewater level inside the treatment tank rises. After the wastewater rises to the height of the float ring, the buoyancy pushes the float ring upward, further driving the filter cartridge to slide upward. This causes multiple thrust blocks to move upward together and the twisting blocks to move upward, so that multiple cross grooves engage with multiple insert blocks. At this time, the rotation of the drive rod is transmitted to the twisting blocks through multiple insert blocks, thereby driving the filter cartridge to rotate under the connected action of multiple thrust blocks. When the filter cartridge rotates, centrifugal force is generated, which throws off the accumulated deposits on the outer wall, thereby restoring the filter cartridge.

[0020] 2. In this invention, when multiple thrust blocks move upward with the filter cartridge, the positioning pin moves upward synchronously, allowing it to insert into the guide groove. As the thrust blocks rotate, they drive the double-sided rack to rotate as well. This causes the positioning pin to slide along the inner wall of the guide groove while rotating radially around the drive rod. Consequently, the double-sided rack slides back and forth along the outer wall of the smooth rod while rotating radially along the drive rod, driving the meshing gear to rotate in both directions. Furthermore, connected to the backlash shaft, multiple fan plates continuously rotate in both directions, displacing any water that has not yet been discharged from the limiting sleeve. This causes the water inside the limiting sleeve to be fanned towards the inner wall of the filter cartridge, thus flushing the inner wall and filter holes of the filter cartridge and further improving the cleaning effect on the filter cartridge surface.

[0021] 3. In this invention, when the filter cartridge moves upward, it drives the support seat to move upward through multiple thrust blocks, which in turn drives the connecting ring to move upward. When the connecting ring moves upward, it pushes the two flipping plates upward, and the two flipping plates flip upward until they form a closure with the bottom of the dispensing tube. At this time, the disinfectant powder inside the dispensing tube cannot be added downward, thus avoiding the waste of disinfectant powder.

[0022] 4. In this invention, when the filter cylinder is lifted up and down by the buoyancy of the float ring and the wastewater, it will drive the fixed ring to move synchronously, thereby driving the inner block to move upward together, further driving the connecting block to move upward, and under the connecting action of the telescopic rod, driving the plunger to move upward, so that the plunger blocks the inner wall of the outlet hole. At this time, the power plant wastewater can no longer be transported into the interior of the treatment tank, thereby avoiding the situation of excessive accumulation of power plant wastewater inside the treatment tank.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example: Please refer to Figures 1-10The power plant wastewater treatment, recycling, and reuse equipment shown includes a treatment tank 1. A water outlet pipe 102 is fixedly connected to the bottom of the treatment tank 1, communicating with the interior of the treatment tank 1. A filter assembly 2 is movably installed inside the treatment tank 1. The filter assembly 2 includes a limiting sleeve 201, which is fixedly connected to the bottom wall of the treatment tank 1. Three water passage grooves 202 are formed through the outer wall of the limiting sleeve 201. A filter cylinder 203 is slidably installed around the limiting sleeve 201. A float ring 204 is fixedly connected to the upper part of the outer wall of the filter cylinder 203. Multiple thrust blocks 205 are fixedly connected to the upper part of the inner wall of the filter cylinder 203. A twisting block 206 is fixedly connected to the near ends of the multiple thrust blocks 205. The top center of the twisting block 206 extends downwards. A cross groove 207 is provided through the treatment tank 1. A drive rod 208 is rotatably connected between the bottom wall and the top wall of the treatment tank 1. A torque block 209 is fixedly connected to the outer wall of the drive rod 208. Multiple insert blocks 2010 are fixedly connected to the outer wall of the torque block 209. The multiple insert blocks 2010 are adapted to the multiple cross grooves 207. The multiple insert blocks 2010 are located above the torque block 206. The top of the thrust block 205 has two sliding holes 2005 that are opened downward. An AC motor 5 is fixedly connected to the bottom of the treatment tank 1. The output shaft of the AC motor 5 is movably connected through the bottom of the treatment tank 1. A watertight bearing is provided between the outer wall of the output shaft of the AC motor 5 and the through hole of the treatment tank 1. The top of the output shaft of the AC motor 5 is fixedly connected to the bottom of the drive rod 208 through a coupling.

[0036] Specifically, the AC motor 5 drives the drive rod 208 to rotate, connecting the inlet pipe 101 to the power plant wastewater outlet pipe via a flange. Power plant wastewater is then transported into the valve body 6 through the inlet pipe 101. After entering through the inlet hole 601, the wastewater flows into the treatment tank 1 from the bottom of the outlet hole 602. Subsequently, the wastewater is filtered by the filter cartridge 203 and then enters the limiting sleeve 201 through the water trough 202. During this process, disinfectant powder inside the two hoppers 402 is added downwards through the two dispensing pipes 4 to disinfect the filtered wastewater, which is then slowly discharged to the outside through the outlet pipe 102. As the filter cartridge 203 filters the wastewater, foreign matter in the wastewater accumulates on the outer wall of the filter cartridge 203. As the amount of deposits on the outer wall of the filter cartridge 203 increases, it will cause… As the filtration speed of the filter cartridge 203 gradually decreases, the wastewater level inside the treatment tank 1 rises until it reaches the height of the float ring 204. The buoyancy of the wastewater pushes the float ring 204 upward, further causing the filter cartridge 203 to slide upward. This causes multiple thrust blocks 205 to move upward together and the twisting block 206 to move upward, resulting in multiple cross grooves 207 engaging with multiple insert blocks 2010. At this time, the rotation of the drive rod 208 is transmitted to the twisting block 206 through multiple insert blocks 2010. Under the combined action of multiple thrust blocks 205, the filter cartridge 203 rotates. When the filter cartridge 203 rotates, it generates centrifugal force, which causes the accumulated material attached to its outer wall to be thrown off, thereby restoring the permeability of the filter cartridge 203.

[0037] In this embodiment, reference is made to Figure 3 , Figure 7 , Figure 8 , Figure 9 As shown, the recoil assembly 3 includes a recoil shaft 301. The outer wall of the recoil shaft 301 is rotatably connected to the inner wall of the sliding hole 2005 via a bearing. Multiple vertically distributed fan plates 302 are fixedly connected to the outer wall of the recoil shaft 301. The multiple fan plates 302 are located inside the limiting sleeve 201. Gears 303 are fixedly connected to the top of each of the multiple recoil shafts 301. Support seats 2014 are fixedly connected to the top of each of the multiple thrust blocks 205. Smooth rods 304 are fixedly connected to the adjacent sides of the multiple support seats 2014. The outer wall of the smooth rod 304... Each of the two sides is slidably connected with a double-sided rack 305, which is located between two sliding holes 2005. The double-sided rack 305 meshes with two gears 303. The top of each double-sided rack 305 is fixedly connected with a positioning pin 306. Four columns 308 are fixedly connected to the top wall of the processing tank 1. The bottom of the four columns 308 is fixedly connected to a cam 309. The bottom of the cam 309 is provided with a guide groove 3010, which is located above the multiple positioning pins 306. The guide groove 3010 is adapted to the multiple positioning pins 306.

[0038] Specifically, as the multiple thrust blocks 205 move upward with the filter cartridge 203, the positioning pin 306 moves upward synchronously, causing it to insert into the guide groove 3010. Furthermore, the rotation of the multiple thrust blocks 205 drives the double-sided rack 305 to rotate as well, further causing the positioning pin 306 to slide along the inner wall of the guide groove 3010 while rotating radially around the drive rod 208. This results in the double-sided rack 305 rotating radially along the drive rod 208. Simultaneously, it slides back and forth along the outer wall of the smooth rod 304, thereby driving the gear 303 meshing with it to rotate back and forth. Furthermore, under the connection of the backlash shaft 301, it drives multiple fan plates 302 to continuously rotate back and forth, pushing the water that has not yet been discharged from the limiting sleeve 201, so that the water inside the limiting sleeve 201 is fanned by the fan plates 302 towards the inner wall of the filter cartridge 203, thereby flowing and flushing the inner wall and filter holes of the filter cartridge 203, thereby further improving the cleaning effect on the surface of the filter cartridge 203.

[0039] In this embodiment, reference is made to Figure 6 As shown, multiple stop blocks 2011 are fixedly connected to the upper part of the outer wall of the torsion block 209, and the multiple stop blocks 2011 are distributed between two adjacent insert blocks 2010.

[0040] Furthermore, by setting multiple stop blocks 2011, the upper stop position of the twist block 206 is prevented, thus avoiding excessive upward movement of the twist block 206.

[0041] In this embodiment, reference is made to Figure 4 As shown, a corrugated sleeve 2012 is fixedly connected to the bottom of the filter cartridge 203, and a universal connector 2013 is fixedly connected to the bottom of the corrugated sleeve 2012. The universal connector 2013 is located outside the limiting sleeve 201, and the universal connection end of the universal connector 2013 is fixedly connected to the bottom wall of the treatment tank 1.

[0042] Furthermore, by setting the corrugated sleeve 2012, the filter cartridge 203 can move freely up and down. At the same time, the connection between the corrugated sleeve 2012 and the universal connector 2013 can also achieve a sealing effect between the bottom of the filter cartridge 203 and the bottom wall of the treatment tank 1, preventing water leakage from the bottom of the filter cartridge 203. The universal connector 2013 allows the filter cartridge 203 and the treatment tank 1 to rotate relative to each other, so that the filter cartridge 203 will not be interfered with by the bottom wall of the treatment tank 1 when rotating.

[0043] In this embodiment, reference is made to Figure 8 As shown, a return spring 307 is fixedly connected to each side of the double-sided rack 305 near the support base 2014. The return spring 307 is located on the periphery of the smooth rod 304, and the end of the return spring 307 is fixedly connected to the side of the support base 2014.

[0044] Furthermore, once the surface of the filter cartridge 203 is cleaned, the filter cartridge 203 regains its filtering properties. The wastewater accumulated inside the treatment tank 1 gradually flows into the filter cartridge 203, causing the wastewater level inside the treatment tank 1 to gradually decrease. When the float ring 204 can no longer receive the buoyancy provided by the wastewater, it will move downwards under the gravity of the filter cartridge 203. This will cause the positioning pin 306 to move downwards and separate from the guide groove 3010. At this time, the double-sided rack 305 stops its reciprocating swing. Thus, under the elastic force stored in the return spring 307 when the double-sided rack 305 swings, it pushes the double-sided rack 305 back to its original position, thus facilitating the next reconnection of the positioning pin 306 and the guide groove 3010.

[0045] In this embodiment, reference is made to Figure 3 , Figure 5 As shown, a connecting ring 2015 is fixedly connected to the top of multiple support bases 2014. Two dispensing pipes 4 are fixedly connected to the top of the processing tank 1. The two dispensing pipes 4 extend into the interior of the processing tank 1. The bottom of each of the two dispensing pipes 4 is rotatably connected to a flipping plate 401 via a hinge. The bottom of the two flipping plates 401 abuts against the top of the connecting ring 2015. A hopper 402 is fixedly connected to the top of each of the two dispensing pipes 4.

[0046] Furthermore, when the filter cartridge 203 moves upward, it drives the support base 2014 to move upward through multiple thrust blocks 205, which in turn drives the connecting ring 2015 to move upward. When the connecting ring 2015 moves upward, it pushes the two flipping plates 401 upward, causing the two flipping plates 401 to flip upward until they form a closure with the bottom of the dispensing tube 4. At this point, the disinfectant powder inside the dispensing tube 4 cannot be added downward, thus avoiding waste of disinfectant powder.

[0047] In this embodiment, reference is made to Figure 1 , Figure 2 , Figure 10As shown, a water inlet pipe 101 is fixedly connected to the upper part of the outer wall of the treatment tank 1, and the water inlet pipe 101 communicates with the interior of the treatment tank 1. A valve body 6 is fixedly connected to the inner wall of the treatment tank 1. A water inlet hole 601 is opened on the side of the valve body 6 that contacts the treatment tank 1. The position of the water inlet hole 601 matches that of the water inlet pipe 101. A water outlet hole 602 is opened at the bottom of the valve body 6, and the water outlet hole 602 communicates with the water inlet hole 601. A telescopic hole 603 is opened at the top of the valve body 6, and the telescopic hole 603 communicates with the water outlet hole 602. A telescopic rod 604 is slidably connected to the inner wall of the telescopic hole 603. A plunger 605 is fixedly connected to the bottom end of the telescopic rod 604. The plunger 605 is located below the opening of the water outlet 602. The outer wall of the plunger 605 is adapted to the size of the inner wall of the water outlet 602. A connecting block 606 is fixedly connected to the top of the telescopic rod 604. A fixing ring 7 is fixedly connected to the upper part of the outer wall of the filter cartridge 203. An annular inner groove 701 is opened on the outer wall of the fixing ring 7. An inner block 8 is rotatably connected inside the annular inner groove 701. The outer wall of the inner block 8 is fixedly connected to one end of the connecting block 606. Two O-rings distributed vertically are fixedly connected to the outer wall of the plunger 605.

[0048] Furthermore, when the filter cartridge 203 is lifted up and down by the buoyancy of the float ring 204 and the wastewater, it will drive the fixed ring 7 to move synchronously, thereby driving the inner block 8 to move upward together, further driving the connecting block 606 to move upward, and under the connection of the telescopic rod 604, driving the plunger 605 to move upward, so that the plunger 605 blocks the inner wall of the outlet hole 602. At this time, the power plant wastewater can no longer be transported into the interior of the treatment tank 1, thereby avoiding the situation of excessive accumulation of power plant wastewater inside the treatment tank 1.

[0049] When the power plant wastewater treatment, recycling, and reuse equipment in this scheme is in operation, the AC motor 5 is started to drive the drive rod 208 to rotate, connecting the inlet pipe 101 to the power plant wastewater outlet pipe through a flange. The power plant wastewater is then transported into the valve body 6 through the inlet pipe 101. After entering through the inlet hole 601, the wastewater flows into the treatment tank 1 from the bottom of the outlet hole 602. Subsequently, the wastewater is filtered through the filter cartridge 203 and then enters the limiting sleeve 201 through the water trough 202. During this process, disinfectant powder inside the two hoppers 402 is added downwards through the two dispensing pipes 4 to disinfect the filtered wastewater. The water outlet 102 slowly discharges water to the outside. As the filter cartridge 203 filters the wastewater, foreign matter in the wastewater accumulates on the outer wall of the filter cartridge 203. As the amount of deposits on the outer wall of the filter cartridge 203 increases, the filtration speed of the filter cartridge 203 gradually decreases. Subsequently, the wastewater level inside the treatment tank 1 rises until the wastewater reaches the height of the float ring 204. The buoyancy of the wastewater pushes the float ring 204 upward, further driving the filter cartridge 203 to slide upward. When the filter cartridge 203 moves upward, it drives the thrust block 205 and the support base 2014 to move upward, further driving the connecting ring 20 When the connecting ring 2015 moves upward, it pushes the two flipping plates 401 upward, causing them to flip upward until they close with the bottom of the dispensing pipe 4. At this point, the disinfectant powder inside the dispensing pipe 4 can no longer be added downward, thus avoiding waste of disinfectant powder. During this process, the fixing ring 7 also moves upward along with the filter cartridge 203, thereby driving the inner block 8 to move upward as well, further driving the connecting block 606 to move upward, and under the connection of the telescopic rod 604, driving the plunger 605 to move upward, so that the plunger 605 blocks the inner wall of the outlet hole 602. At this point, the power plant wastewater cannot continue to flow. The wastewater continues to be transported into the treatment tank 1, thereby preventing excessive accumulation of power plant wastewater inside the treatment tank 1. When the thrust block 205 moves upward, it also drives the twisting block 206 to move upward, so that multiple cross grooves 207 engage with multiple insert blocks 2010. At this time, the rotation of the drive rod 208 is transmitted to the twisting block 206 through multiple insert blocks 2010, thereby driving the filter cartridge 203 to rotate under the connection of multiple thrust blocks 205. When the filter cartridge 203 rotates, it generates centrifugal force, which causes the accumulated material attached to its outer wall to be thrown off under the centrifugal force of the rotating filter cartridge 203, thereby restoring the permeability of the filter cartridge 203.

[0050] As the multiple thrust blocks 205 move upward with the filter cartridge 203, the positioning pin 306 moves upward synchronously, inserting into the guide groove 3010. The rotation of the thrust blocks 205 causes the double-sided rack 305 to rotate as well, further causing the positioning pin 306 to slide along the inner wall of the guide groove 3010 while rotating radially around the drive rod 208. This causes the double-sided rack 305 to slide back and forth along the outer wall of the smooth rod 304 while rotating radially along the drive rod 208, thus driving the meshing gear 303 to rotate back and forth. Furthermore, connected to the backwash shaft 301, this causes the multiple fan plates 302 to continuously rotate forward and backward, displacing the water that has not yet been discharged from the limiting sleeve 201. The water inside the limiting sleeve 201 is then fanned by the fan plates 302 towards the inner wall of the filter cartridge 203, thereby flushing the inner wall and filter holes of the filter cartridge 203 and further improving the cleaning effect on the surface of the filter cartridge 203.
