[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1: Please refer to Figures 1-6 This utility model provides the following technical solution: A combined water treatment device based on pressurized backwashing, comprising a filter tank 1, an inlet 101 at the end of the filter tank 1, a filter layer 102 inside the filter tank 1, a clean water outlet pipe 103 at the bottom of the filter tank 1, and a backwashing mechanism for cleaning the filter layer 102 at the end of the filter tank 1. The backwashing mechanism includes a flushing tank 2 at the end of the filter tank 1, and a flushing pump 202 is fixedly installed on the outer wall of the flushing tank 2. A pressure valve 104 is provided on the outer wall of the clean water outlet pipe 103, and a controller 105 is fixedly installed on the outer wall of the pressure valve 104. The flushing tank 2 is equipped with an inlet pipe 201 at the top, and the filter tank 1 is equipped with a sewage delivery pipe 301 at the bottom. The flushing tank 2 is located at the end of the filter tank 1 where the clean water outlet pipe 103 is located. The flushing pump 202 is located between the filter tank 1 and the flushing tank 2, and both ends of the flushing pump 202 are connected to the filter tank 1 and the flushing tank 2 respectively. The controller 105 is electrically connected to the flushing pump 202, and the controller 105 controls the start and stop of the flushing pump 202 through the pressure valve 104. The water inlet 101 and the water inlet pipe 201 are both connected to an external water source. The sewage delivery pipe 301 is located at the bottom of the filter tank 1 at the end away from the clean water delivery pipe.
[0027] The water to be treated flows into the filter tank 1 from the external water source through the inlet 101. The water flows from top to bottom through the filter layer 102, and impurities and particles in the water are effectively intercepted by the filter layer 102. The purified water then gathers at the bottom of the filter tank 1 and flows out through the clean water outlet pipe 103 to provide clean water for users. During continuous operation of the device, the filter layer 102 will inevitably become clogged due to the accumulation of impurities, resulting in increased filtration resistance. At this time, the water pressure in the clean water outlet pipe 103 will change accordingly. The pressure valve 104 can transmit the water pressure data to the controller 105 in real time. When the water pressure data exceeds the preset normal range, the controller 105 will immediately start the flushing pump 202 to pressurize the water injected into the flushing tank 2 through the inlet pipe 201. The pressurized water flow will flow back into the filter tank 1 to perform a powerful backwash on the filter layer 102. The reverse high-pressure water flow can wash away the impurities attached to the filter layer 102 and discharge them from the filter tank 1 through the sewage conveying pipe 301 with the water flow, thereby restoring the cleanliness of the filter layer 102 and ensuring the continuous and efficient operation of the device.
[0028] Example 2: Based on Example 1, a collection mechanism is also disclosed, the specific structure of which is as follows: A collection mechanism for backwashing wastewater recovery is provided at the end of the wastewater conveying pipe 301. The collection mechanism includes a recovery box 3 located at the end of the wastewater conveying pipe 301, and a collection box 4 is slidably installed inside the recovery box 3. A filter plate 401 is provided at the bottom of the filter box. A conveying pump 303 is fixedly installed on the outer wall of the recovery box 3. A drain pipe 302 is provided at the bottom of the recovery box 3. A slider 402, a magnetic block 403, and a handle 404 are fixedly installed on the outer wall of the collection box 4. One end of the conveying pump 303 is fixedly installed to the bottom of the recovery box 3. The connecting pipe 304 is connected to the other end of the pump 303, and the other end of the pump 303 is fixedly installed with a recycling pipe 203 that is connected to the flushing tank 2. The collection box 4 is set inside the recycling box 3 in correspondence with the sewage conveying pipe 301. The outer wall of the end of the collection box 4 is fixedly installed with a sealing ring 5 that fits the outer wall of the recycling box 3. The slider 402 is symmetrically arranged on both sides of the outer wall of the collection box 4. The outer wall of the recycling box 3 is provided with a sliding groove corresponding to the collection box 4 and the slider 402. Multiple sets of magnetic blocks 403 are symmetrically arranged on the outer wall of the collection box 4. The outer wall of the recycling box 3 is provided with an adsorption groove 305 corresponding to the magnetic blocks 403.
[0029] When the backwashing process starts, the wastewater discharged from the filter tank 1 flows directly into the recovery tank 3 through the wastewater conveying pipe 301. The wastewater first impacts the collection box 4, where the filter plate 401 at the bottom of the collection box 4 performs preliminary filtration and interception of large particles and some suspended solids in the wastewater, preventing these impurities from entering the bottom of the recovery tank 3 and interfering with the normal operation of the conveying pump 303. The wastewater filtered by the filter plate 401 collects at the bottom of the recovery tank 3 under the action of gravity. At this time, the conveying pump 303 starts working, drawing the wastewater from the bottom of the recovery tank 3 through the connecting pipe 304 and conveying it to the flushing tank 2 along the recovery pipe 203. 4. When cleaning is required, the operator only needs to hold the handle 404 and use the sliders 402 symmetrically arranged on the outer wall of the collection box 4 to slide it in the groove opened on the outer wall of the recycling bin 3. The collection box 4 can be easily pulled out of the recycling bin 3. After cleaning, push the collection box 4 back to its original position. The magnetic block 403 on the outer wall of the collection box 4 will automatically be attracted to the corresponding adsorption groove 305 on the outer wall of the recycling bin 3, ensuring that the collection box 4 is installed firmly. At the same time, the sealing ring 5 attached to the outer wall at the end of the collection box 4 can effectively prevent sewage leakage, ensuring the smoothness and environmental protection of the entire sewage recycling process, and realizing the recycling and efficient treatment of water resources.
