Description

Technical Field

[0001] This invention relates to the field of liquid waste treatment technology, and more specifically to a guiding, separating and diverting device for liquid sewage filtration and treatment. Background Technology

[0002] Liquid manure filtration is a core pre-treatment step in pollution control and resource utilization in livestock and poultry farming. It can efficiently separate solids and liquids in manure, significantly reducing COD, ammonia nitrogen, suspended solids, and pathogens, thus preventing the risks of eutrophication, soil salinization, odor spread, and disease transmission caused by direct discharge of manure from the source. It can also convert the separated solid residue into organic fertilizer raw materials, and the treated liquid can meet discharge standards or be reused for farmland irrigation and pen flushing, achieving manure reduction, harmlessness, and resource utilization, alleviating agricultural non-point source pollution, promoting the development of integrated crop and livestock circular agriculture, and helping farms meet environmental regulatory requirements and reduce compliant operating costs.

[0003] Refer to the relevant patent CN119075485A. Its essence is to use the main rotational motion of the rotating filter screen as the sole power source, and simultaneously link three anti-clogging mechanisms: a planetary self-rotating cutting mechanism to break up large particles on the fixed filter screen online and self-clean the filter plate; a counterweight centrifugal stirring rod to disperse the accumulated material in the middle of the two layers of filter screen; and a reciprocating cleaning mechanism with intermittent rubber block movement and spring reset to simultaneously scrape the bottom of the upper and lower filter screens, holes and inner wall of the tank. This achieves continuous anti-clogging graded solid-liquid separation without additional power throughout the entire process, solving the pain points of traditional sewage filtration that is prone to clogging, requires frequent shutdown for cleaning and has a complex structure.

[0004] Currently, liquid sewage filtration treatment mostly adopts static multi-layer filter gravity filtration, single rotating filter mechanical scraping filtration, or step-by-step treatment of filtration and sedimentation separation. These treatment methods have many inconveniences: static filter media accumulates material quickly and is prone to clogging, requiring frequent shutdowns for manual disassembly and cleaning, resulting in low treatment efficiency and high labor intensity; single mechanical scraping can only clean the surface of the filter screen and cannot penetrate into the filter screen pores and the inner wall of the tank. Large particles of impurities that are not pre-crushed can easily cause filter screen damage, and they generally lack sterilization function, so the sewage still carries a large number of pathogens after treatment.

[0005] Therefore, a continuous treatment system integrating filtration and sedimentation should be constructed by combining centrifugal guided separation and gradient filtration technologies with high-temperature pressurized airflow to achieve simultaneous sterilization and online cleaning of filter media during the filtration process. A purely mechanical linkage mechanism should be used to achieve automatic switching and interlocking control of the filtration, liquid storage, and sludge discharge processes. Furthermore, a water-driven quantitative dosing method should be adopted to achieve precise matching of flocculant and liquid inflow. To this end, we provide a guided separation and diversion device for liquid sewage filtration treatment to solve the above problems. Summary of the Invention

[0018] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0019] 1. This invention provides a guiding separation and diversion device for liquid sewage filtration. The device drives a rotary joint to rotate at high speed through a power component. A pressurizer pressurizes and delivers gas to the gas heater. The heated high-temperature gas is introduced into the filter chamber through the jet nozzle on the surface of the rotating shaft. At this time, liquid sewage is injected into the filter chamber through the feed end and guided by the guide slope to collect on the top surface of the baffle. The high-speed rotating shaft drives the baffle to quickly agitate the liquid, generating centrifugal force inside the liquid, which helps to separate large particles of impurities from the liquid, while ensuring that the liquid quickly permeates through the movable filter screen to enter the next stage of filtration unit.

[0020] When the movable filter screen filters the liquid, the high-temperature airflow from the jet nozzle performs preliminary high-temperature sterilization on the liquid, assists in the high-temperature inactivation of pollutants in the liquid, reduces the probability of their adhesion to the inner wall of the equipment and the surface of the filter material, and increases the gas pressure inside the filter chamber, providing pressure guarantee for the stable operation of subsequent units.

[0021] After the filtration operation is completed, the limiting ring is fixed at the high positioning point. At this time, the sliding rod drives the movable filter screen to detach from the surface of the partition. The rotating shaft continues to drive the partition to rotate, and the airflow blows and cleans the surface of the movable filter screen. The impurities trapped on the surface of the movable filter screen and the impurities remaining on the top surface of the partition are discharged to the designated collection area through the impurity discharge end of the filter chamber.

[0022] 2. This invention provides a guiding separation and diversion device for liquid sewage filtration treatment. When the movable filter screen is in the filtration operation state, the linkage contact rod at the bottom of the limiting ring applies pressure to the top of the sealing block. One end of the sealing block is engaged inside the guide funnel, thereby closing the outlet pipe. After the liquid has been filtered by two sets of movable filter screens to remove large particles, it drips onto the top surface of the annular guide scraper. Under the combined action of the liquid's own gravity and the gas pressure inside the filter chamber, the annular guide scraper slides down along the limiting slide rod and drives the plug rod to insert into the liquid outlet through the limiting slide rod, thereby temporarily sealing the water tank and preventing fluctuations in the output water flow rate of the water tank from affecting subsequent processes.

[0023] The annular guide scraper sinks to the appropriate height according to the actual values ​​of water flow pressure and air flow pressure, and performs deep filtration of water flow through a fine filter screen to ensure that the liquid impurity content collected in the water tank is lower than the preset threshold.

[0024] After the filtration operation is completed, the liquid pressure and gas pressure on the top surface of the annular guide scraper are released, and the reset spring drives the annular guide scraper to reset. During the reset process, the annular guide scraper scrapes off the residual impurities trapped on the top surface of the fine filter screen and collects them on its own top surface. At the same time, the plug rod is pulled out from the inside of the liquid outlet, the air inlet valve is opened, and the liquid in the water tank is transported to the sedimentation and purification unit at a constant flow rate using the air pressure.

[0025] By adjusting the position of the limit ring, the linkage contact rod releases the pressure on the sealing block, and the sealing block resets under the elastic thrust of the spring. The impurities discharged from the filter chamber and the impurities collected on the top surface of the annular guide scraper are discharged from the outside of the equipment through the impurity outlet pipe under the thrust of the airflow.

[0026] 3. This invention provides a guiding separation and diversion device for liquid sewage filtration treatment. Liquid flows into the outlet funnel through the outlet and is then guided into the mixing tube through the guide pipe. Under the synergistic effect of the liquid thrust and the guide groove on the surface of the flocculant dipping wheel, the flocculant dipping wheel rotates at an appropriate speed. During the rotation of the flocculant dipping wheel, the guide groove on its surface dips the flocculant stored in the agent storage chamber into the mixing tube and mixes it thoroughly with the water before conveying it into the mixing chamber.

[0027] When the water tank stops supplying liquid, under the pressure of the airflow, the liquid inside the guide pipe is completely transported to the mixing pipe and flows into the mixing chamber. After a preset reaction and sedimentation time, the impurities in the liquid are collected at the bottom of the mixing chamber. When discharging the liquid inside the mixing chamber, the three-way valve is connected to the discharge pipe. Under the pressure of the liquid, the impurities are transported through the discharge pipe to the discharge pipe and discharged together. The clean liquid is then discharged from another output port to the designated collection location through the switching control of the three-way valve. Attached Figure Description

[0036] The present invention will be further described in detail below with reference to embodiments:

[0037] Example 1: As Figure 1-7 As shown, the present invention provides a guiding separation and diversion device for liquid sewage filtration treatment, including a support 1. The top surface of the support 1 is provided with a sewage filtration unit 2 for quickly cleaning up solid impurities after filtration. The output end of the sewage filtration unit 2 is provided with a sedimentation and purification unit 3 for adding flocculant as it flows with the water flow. The sewage filtration unit 2 includes a water tank 21 fixedly installed on the top surface of the support 1 for storing filtered sewage, a filter chamber 22 set on the top surface of the water tank 21 for filtering sewage multiple times, and a partition chamber 215 fixedly connected inside the water tank 21 for separating the water flow and solid impurities.

[0038] The compressor 23 is equipped with dual output ports, one of which is connected to the gas heater 24. The gas heater 24 heats the airflow output by the compressor 23 to ensure that the airflow temperature entering the filter chamber 22 is within the preset suitable range. The power component 25 consists of a drive motor, a reduction mechanism and a transmission wheel. Its internal transmission wheel is connected to the outer surface of one end of the rotary joint 26 through a transmission belt.

[0039] A pressurizer 23 is fixedly connected to the side of the water tank 21. A gas heater 24 is fixedly connected to one end of the output end of the pressurizer 23. A power assembly 25 is provided at one end of the top surface of the filter chamber 22. A rotary joint 26 is rotatably connected inside the top surface of the filter chamber 22. The output end of the gas heater 24 is movably connected inside the top surface of the rotary joint 26. A rotating shaft 28 is fixedly connected to the bottom surface of the rotary joint 26. The rotating shaft 28 is rotatably connected inside the filter chamber 22.

[0040] The filter chamber 22 and the water tank 21 are separated and sealed by the partition chamber 215. The two sets of guide ramps 214 arranged inside the filter chamber 22 are matched one by one with the partition plate 29 fixedly installed on the surface of the rotating shaft 28. The inclined plate 210 mounted on the top surface of the partition plate 29 can drive the water flow to generate centrifugal force during rotation, so that the water flow is dispersed in all directions.

[0041] A jet nozzle 27 is provided at the bottom side of the rotating shaft 28. Two partitions 29 are fixedly connected to the bottom of the outer surface of the rotating shaft 28. Multiple inclined plates 210 are fixedly connected evenly on the top surface of the partitions 29. A slide rod 212 is slidably connected inside the top surface of the filter chamber 22. One end of the slide rod 212 passes through the top surface of the filter chamber 22 and is fixedly connected to a limiting ring 211. The limiting ring 211 is slidably connected to the top of the outer surface of the filter chamber 22. Two movable filter screens 213 are fixedly connected to the outer surface of the slide rod 212. Two guide ramps 214 are fixedly connected inside the filter chamber 22. The movable filter screens 213 are slidably connected inside the guide ramps 214.

[0042] The slide rod 212 fixes two sets of movable filter screens 213 into one piece. The mesh count of the two sets of movable filter screens 213 increases gradually from top to bottom in the vertical direction. The slide rod 212 is slidably connected to the groove opened on the top surface of the guide slope 214 and can slide along the groove. The side wall of the filter chamber 22 is provided with threaded holes for positioning the limiting ring 211. The working position of the movable filter screen 213 can be precisely controlled by adjusting the height of the limiting ring 211. When in operation, the movable filter screen 213 surrounds the outside of the partition 29 and performs lateral filtration on the water flow formed by the agitation of the partition 29. The bottom middle section of the limiting ring 211 is provided with a linkage contact rod to realize mechanical linkage with the subsequent execution structure.

[0043] In this embodiment, the rotary joint 26 is driven to rotate at high speed by the power component 25, and the pressurizer 23 pressurizes and delivers the gas to the gas heater 24. The heated high-temperature gas is introduced into the filter chamber 22 through the jet nozzle 27 on the surface of the rotating shaft 28. At this time, liquid sewage is injected through the feed end of the filter chamber 22 and guided by the guide ramp 214 to collect on the top surface of the partition 29. The high-speed rotating shaft 28 drives the partition 29 to quickly agitate the liquid, so that centrifugal force is generated inside the liquid, which helps to separate large particles of impurities from the liquid, while ensuring that the liquid quickly permeates through the movable filter screen 213 to enter the next stage of filtration unit.

[0044] When the movable filter 213 filters the liquid, the high-temperature airflow ejected from the jet nozzle 27 performs preliminary high-temperature sterilization on the liquid, assists in the high-temperature inactivation of pollutants in the liquid, reduces the probability of their adhesion to the inner wall of the equipment and the surface of the filter material, and increases the gas pressure inside the filter chamber 22 to provide pressure guarantee for the stable operation of subsequent units.

[0045] After the filtration operation is completed, the limiting ring 211 is fixed at the high positioning point. At this time, the slide rod 212 drives the movable filter screen 213 to detach from the surface of the partition 29. The rotating shaft 28 continues to drive the partition 29 to rotate, and the airflow blows and cleans the surface of the movable filter screen 213. The impurities trapped on the surface of the movable filter screen 213 and the impurities remaining on the top surface of the partition 29 are discharged to the designated collection area through the impurity discharge end of the filter chamber 22.

[0046] Example 2: Figure 1-7As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, an air inlet valve 216 is fixedly connected to one end of the top surface of the water tank 21, and the other output end of the pressurizer 23 is fixedly connected to the input end of the air inlet valve 216. Two liquid outlets 217 are opened on the bottom surface of the inside of the water tank 21. A fine filter screen 218 is fixedly connected inside the partition chamber 215. A flow guide funnel 227 is fixedly connected inside the top surface of the fine filter screen 218. A flow guide cover 226 is fixedly connected to the top surface of the fine filter screen 218. A sealing block 224 is slidably connected inside the flow guide cover 226. A spring 225 is provided at one end of the outer surface of the sealing block 224. The spring 225 is movably connected inside the flow guide cover 226. One end of the sealing block 224 is movably connected to the input end of the flow guide funnel 227. A waste outlet pipe 219 is fixedly connected to the output end of the flow guide funnel 227. One end of the waste outlet pipe 219 penetrates the bottom surface of the fine filter screen 218.

[0047] The water tank 21 has a reserved cavity for storing the filtered and sterilized liquid. Its bottom surface is provided with two liquid outlets 217. Through the linkage between the annular guide scraper 220, the plug rod 223 and the liquid outlets 217, it is ensured that the on and off states of the water tank 21 and the filter chamber 22 are always linked in opposite directions.

[0048] An annular guide scraper 220 is slidably connected to the outer surface of the fine filter screen 218. A limiting slide rod 221 is fixedly connected to the bottom surface of the annular guide scraper 220. The limiting slide rod 221 is slidably connected to the inside of the bottom surface of the partition chamber 215. One end of the limiting slide rod 221 penetrates the bottom surface of the partition chamber 215 and is fixedly connected to a blocking rod 223. The blocking rod 223 is slidably connected to the inside of the liquid outlet 217. A return spring 222 is provided on the outer surface of the limiting slide rod 221.

[0049] The partition chamber 215 is installed at the drain end of the filter chamber 22. The fine filter screen 218 installed inside it extends into the filter chamber 22 at one end and penetrates into the water tank 21 at the other end to achieve fine filtration of the liquid. One end of the annular guide scraper 220 is always in close contact with the surface of the fine filter screen 218. Under the elastic thrust of the return spring 222, the initial position of the annular guide scraper 220 is flush with the guide funnel 227 installed at the top of the fine filter screen 218, so as to achieve the sealing and blocking of the channel of the fine filter screen 218. The bottom surface of the fine filter screen 218 has a closed structure, and its liquid inlet and liquid outlet are both opened on the side wall.

[0050] Under the elastic force of the spring 225, the sealing block 224 retracts inside the flow guide shroud 226, ensuring that impurities can be transported to the designated collection area through the impurity outlet pipe 219 under the coordinated guidance of the annular flow guide scraper 220 and the flow guide funnel 227. When the movable filter screen 213 is in the filtration position, the linkage contact rod at the bottom of the limiting ring 211 applies pressure to the top of the sealing block 224, so that the sealing block 224 can seal the opening of the flow guide funnel 227.

[0051] In this embodiment, when the movable filter 213 is in the filtration operation state, the linkage contact rod at the bottom of the limiting ring 211 applies pressure to the top of the sealing block 224. One end of the sealing block 224 is engaged inside the guide funnel 227, thereby closing the outlet pipe 219. After the liquid is filtered by the two sets of movable filters 213 to remove large particles of impurities, it drips onto the top surface of the annular guide scraper 220. Under the combined action of the liquid's own gravity and the gas pressure inside the filter chamber 22, the annular guide scraper 220 slides down along the limiting slide rod 221 and drives the plug rod 223 to insert into the liquid outlet 217 through the limiting slide rod 221, thereby temporarily closing the water tank 21 and preventing fluctuations in the output water flow rate of the water tank 21 from affecting subsequent processes.

[0052] The annular guide scraper 220 sinks to the appropriate height according to the actual values ​​of water flow pressure and air flow pressure, and performs deep filtration of water flow through fine filter screen 218 to ensure that the liquid impurity content collected in water tank 21 is lower than the preset threshold.

[0053] After the filtration operation is completed, the liquid pressure and gas pressure on the top surface of the annular guide scraper 220 are released, and the reset spring 222 drives the annular guide scraper 220 to reset. During the reset process, the annular guide scraper 220 scrapes off the residual impurities trapped on the top surface of the fine filter screen 218 and collects them on its own top surface. At the same time, the plug rod 223 is pulled out from the liquid outlet 217 and the air inlet valve 216 is opened. The air pressure is used to transport the liquid in the water tank 21 to the sedimentation and purification unit 3 at a constant flow rate.

[0054] By adjusting the position of the limiting ring 211, the linkage contact rod releases the pressure on the sealing block 224. The sealing block 224 is reset under the elastic thrust of the spring 225. The impurities discharged from the inside of the filter chamber 22 and the impurities collected on the top surface of the annular guide scraper 220 are discharged to the outside of the equipment through the impurity outlet pipe 219 under the action of airflow thrust.

[0055] Example 3: As Figure 1-7As shown, based on Example 1, the present invention provides a technical solution: Preferably, the precipitation and purification unit 3 includes an outlet funnel 31 fixedly installed at the output end of the water tank 21 for guiding the flow, a mixing pipe 33 set at the output end of the outlet funnel 31 for mixing water flow and flocculant, and a mixing chamber 34 fixedly installed at the output end of the mixing pipe 33 for the reaction container of water flow and flocculant.

[0056] The impurity outlet pipe 219 penetrates the bottom surface of the liquid outlet funnel 31 and the guide pipe 32, and transports the impurities to the outside of the equipment. The liquid outlet funnel 31 and the guide pipe 32 are both independent structures that are not connected to the impurity outlet pipe 219. The flocculant dipping wheel 39 is made of lightweight material and has a guide groove for auxiliary liquid driving on its surface. The flocculant dipping wheel 39 arranged inside the mixing pipe 33 achieves unidirectional rotation limit through the ratchet mechanism. At the same time, it can seal and stop the mixing pipe 33 to prevent the liquid inside the mixing chamber 34 from backflowing.

[0057] The liquid outlet funnel 31 is fixedly connected to the output end of the liquid outlet 217. A guide pipe 32 is fixedly connected to the bottom surface of the liquid outlet funnel 31. One end of the impurity outlet pipe 219 passes through the bottom surface of the guide pipe 32. The mixing pipe 33 is fixedly connected to the side of the guide pipe 32. A plug 35 is threadedly connected to the top surface of the mixing chamber 34. A three-way valve 36 is fixedly connected to the bottom surface of the mixing chamber 34. A discharge pipe 37 is fixedly connected to one output end of the three-way valve 36. The discharge pipe 37 is fixedly connected to the inside of the side of the discharge pipe 219. A reagent storage chamber 38 is fixedly connected to the top surface of the mixing pipe 33. A flocculant dipping wheel 39 is installed inside the reagent storage chamber 38.

[0058] In this embodiment, liquid flows into the outlet funnel 31 through the outlet 217, and is then guided into the mixing tube 33 through the guide tube 32. Under the synergistic effect of the liquid thrust and the guide groove on the surface of the flocculant dipping wheel 39, the flocculant dipping wheel 39 rotates at an appropriate speed. During the rotation of the flocculant dipping wheel 39, the guide groove on its surface dips the flocculant stored in the agent storage chamber 38 into the mixing tube 33, and after being fully mixed with the water, it is transported into the mixing chamber 34.

[0059] When the water tank 21 stops supplying liquid, under the action of airflow pressure, the liquid inside the guide pipe 32 is completely transported to the mixing pipe 33 and flows into the mixing chamber 34. After a preset reaction and sedimentation time, the impurities in the liquid are collected at the bottom of the mixing chamber 34. When discharging the liquid inside the mixing chamber 34, the three-way valve 36 is connected to the impurity discharge pipe 37. Under the action of liquid pressure, the impurities are transported through the impurity discharge pipe 37 to the impurity outlet pipe 219 and discharged together. The subsequent clean liquid is discharged from another output port to the designated collection position through the switching control of the three-way valve 36.

[0060] The working principle of the guiding separation and diversion device for liquid sewage filtration and treatment will be explained in detail below.

[0061] like Figure 1-7 As shown, the rotary joint 26 is driven to rotate at high speed by the power component 25, and the pressurizer 23 pressurizes the gas and delivers it to the gas heater 24. The heated high-temperature gas is introduced into the filter chamber 22 through the jet nozzle 27 on the surface of the rotating shaft 28. At this time, liquid sewage is injected through the feed end of the filter chamber 22 and guided by the guide ramp 214 to collect on the top surface of the baffle 29. The high-speed rotating shaft 28 drives the baffle 29 to quickly stir the liquid, so that centrifugal force is generated inside the liquid, which helps to separate large particles of impurities from the liquid, while ensuring that the liquid quickly permeates through the movable filter screen 213 to enter the next stage of filtration unit.

[0062] When the movable filter 213 filters the liquid, the high-temperature airflow ejected from the jet nozzle 27 simultaneously performs two functions: first, it performs preliminary high-temperature sterilization on the liquid, assists in the high-temperature inactivation of pollutants in the liquid, and reduces their adhesion probability on the inner wall of the equipment and the surface of the filter material; second, it increases the gas pressure inside the filter chamber 22, providing pressure assurance for the stable operation of subsequent units.

[0063] When the movable filter screen 213 is in the filtration operation state, the linkage contact rod at the bottom of the limiting ring 211 applies pressure to the top of the sealing block 224, causing one end of the sealing block 224 to be engaged inside the guide funnel 227, thereby closing the impurity outlet pipe 219. After the liquid is filtered by the two sets of movable filter screens 213 to remove large particles of impurities, it drips onto the top surface of the annular guide scraper 220. Under the combined action of the liquid's own gravity and the gas pressure inside the filter chamber 22, the annular guide scraper 220 slides down along the limiting slide rod 221 and drives the plug rod 223 to be inserted into the liquid outlet 217 through the limiting slide rod 221, thereby temporarily closing the water tank 21 and preventing fluctuations in the output water flow rate of the water tank 21 from affecting subsequent processes.

[0064] Subsequently, the annular guide scraper 220 descends to the appropriate height according to the actual values ​​of water flow pressure and air flow pressure, and performs deep filtration of the water flow through the fine filter screen 218 to ensure that the liquid impurity content collected in the water tank 21 is lower than the preset threshold.

[0065] After the filtration operation is completed, the limiting ring 211 is fixed at the high positioning point. At this time, the slide rod 212 drives the movable filter screen 213 to detach from the surface of the partition plate 29. The rotating shaft 28 continues to drive the partition plate 29 to rotate, and the airflow blows and cleans the surface of the movable filter screen 213. The impurities trapped on the surface of the movable filter screen 213 and the impurities remaining on the top surface of the partition plate 29 are guided out of the impurity pipe 219 through the impurity discharge end of the filter chamber 22.

[0066] As the filtration process ends, the liquid and gas pressures on the top surface of the annular guide scraper 220 are released, and the reset spring 222 drives the annular guide scraper 220 to reset. During the reset process, the annular guide scraper 220 scrapes off the residual impurities trapped on the top surface of the fine filter screen 218 and collects them on its own top surface. At the same time, the plug rod 223 is pulled out from inside the liquid outlet 217, and the air inlet valve 216 is opened. The air pressure is used to transport the purified liquid in the water tank 21 to the sedimentation and purification unit 3 at a constant flow rate.

[0067] Since the limiting ring 211 is fixed at a high position, the linkage contact rod releases the pressure on the sealing block 224 simultaneously. The sealing block 224 resets under the elastic thrust of the spring 225. The impurities discharged from the filter chamber 22 and the impurities collected on the top surface of the annular guide scraper 220 are discharged to the outside of the equipment through the impurity outlet pipe 219 under the action of airflow thrust.

[0068] The liquid delivered from the water tank 21 flows into the liquid outlet funnel 31 through the liquid outlet 217, and is then guided into the mixing tube 33 through the guide tube 32. Under the combined action of the liquid thrust and the guide groove on the surface of the flocculant dipping wheel 39, the flocculant dipping wheel 39 rotates at an appropriate speed. The guide groove on its surface dips the flocculant stored in the agent storage chamber 38 into the mixing tube 33, and after being fully mixed with the water, it is delivered into the mixing chamber 34.

[0069] When the water tank 21 stops supplying liquid, under the action of airflow pressure, the residual liquid inside the guide pipe 32 is completely transported to the mixing pipe 33 and flows into the mixing chamber 34. After a preset reaction and sedimentation time, the impurities in the liquid are collected at the bottom of the mixing chamber 34. When discharging the liquid inside the mixing chamber 34, the three-way valve 36 is first connected to the discharge pipe 37. Under the action of liquid pressure, the impurities at the bottom are transported to the discharge pipe 219 through the discharge pipe 37 and discharged together. After the impurities are discharged, the clean liquid is discharged from another output port to the designated collection position through the switching control of the three-way valve 36.

[0070] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements made without departing from the spirit of the present invention are within the scope of protection of the present invention.
