[0038] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0039] 1. Equipped with a double-link multi-barrier assembly, water is directly flushed in through the injection pipe. A staggered, inclined baffle plate, a buffer tank, an isolation partition, and an opening / closing sealing plate create a sharp-angled water-blocking component, restricting the water flow's entry and exit points. The water flow reverses direction at the angle, impacting the incoming water and reducing its velocity at the storage tank. This, combined with controlled outlet size, increases water pressure at discharge, enhancing the discharge speed and impact distance. This process is repeated to accelerate and decelerate the water flow internally, allowing for rapid adjustment during flocculation, mixing, and impurity settling. A drive motor and belt drive rotate the mixing and scraping frame, which, along with the feeding box and rigid pipe, injects flocculant into the storage tank, achieving water impact and mixing. Electric actuators drive the inlet / outlet swing frame, internal reversing block, and contact reverse... The oscillating impeller, utilizing the coordinated action of inclined limiting and reversing plates and contact reversing plates, achieves reverse flushing from top to bottom and multi-position arc-shaped counter-flushing from the side end, creating turbulence and slowing the water flow. This allows impurities to gradually settle under gravity. Combined with a multi-hole exhaust pipe frame and air pump, the system aerates and cleans the water. Utilizing inclined inlet baffles, upper flushing limits, multi-position internal flushing buffering, and continuous feeding for flocculation and mixing, along with multi-stage deceleration, the system reduces water flow velocity while simultaneously flocculating impurities. High-speed external flushing and interception deceleration work together to significantly slow the water flow, resulting in slow and continuous sedimentation of impurities. This multi-position cleaning system enables continuous rainwater treatment during recovery, reducing waiting time and ensuring high recovery and utilization speeds, thus improving overall efficiency.

[0040] 2. Water is flushed into the dual-chamber segmented tank via the inlet / outlet pipe rack and extraction pump. The drive motor and multi-axis gearbox drive the centrifugal mixing rack and centrifugal feeding tray to rotate rapidly. The external push linkage plate pushes the agent in the storage fixed tank into the inner side of the dual-chamber segmented tank through the feeding pipe, realizing centrifugal feeding and centrifugal mixing. Overflow treatment is achieved with the external discharge feeding pipe. Impurities are fully removed by the multi-section interception mesh plate and the cleaning sliding plate. The drive motor and belt drive box drive the multi-hole mixing rack to rotate, and sterilization and bleaching agents are added to the centralized reaction tank with the feeding pipe rack and extraction pump, realizing the full purification and slag removal of rainwater. Through the centrifugal mixing of flushing water and agents, the agent feed rate is controlled according to the stirring speed. With the synchronous linkage of inlet and outlet and the interception and slag removal treatment, continuous slag removal and slag removal treatment is achieved, improving the effect and efficiency of rainwater purification.

[0041] 3. By employing inlet deceleration, outflow impact, flocculation mixing, rising interception, inclined discharge buffer interception, aeration sludge removal and drainage, re-mixing at the same speed, overflow interception and drainage, and stirring and mixing, this technology effectively solves the problem of excessively long processing times and large storage devices in existing technologies for rainwater recycling. It enables rainwater to be processed in a flowing manner, reducing waiting time, achieving synchronous coordination of inlet and outlet water, enabling rapid sludge removal and recycling, reducing the size of the treatment and storage devices, and effectively improving the efficiency of rainwater treatment, ensuring the timeliness of rainwater treatment and reuse.

[0042] 4. Equipped with a screening and pressing component, the slag discharge electric pusher drives the slag discharge screen plate, and the pressing and sealing electric pusher drives the pressing and sealing integrated plate to open the partition buffer box, pushing out the accumulated impurities inside for slag removal. The alignment electric pusher drives the electromagnetic top limit plate to push the vibrating screen plate up and down, and the spring reset rod drives the vibrating screen plate to rise, realizing position switching. The vibrating pump and spring reset rod drive the vibrating screen plate to vibrate, separating the impurities and water in the mixture, realizing dehydration of the impurity mixture. The sealing electric slide rail drives the sealing combination plate to move, and the pressing hydraulic cylinder drives the pressing and separating plate to push the impurity mixture down. Through the pressing process, a secondary dehydration process is achieved, improving the water recovery rate. The multi-stage dehydration process reduces the water content in the impurities, increases the water recovery volume, and reduces water waste.

[0043] In summary, by combining the dual-barrier components and the screening and pressing components, and utilizing multi-position mixing and slag removal with timed slag discharge and cleaning, continuous rainwater treatment is achieved. Combined with impurity mixing and dewatering treatment and water recirculation treatment, multi-stage slag removal is linked, increasing the speed and volume of rainwater treatment. This effectively improves the speed and volume of rainwater recovery, enabling rainwater recycling and reuse, and ensuring the effective use of water resources. Attached Figure Description

[0087] The working principle and usage process of this invention are as follows: When recycling rainwater from a construction site, water is collected through a collection trough within the site. Workers add flocculant to the inside of the feeding box 209. The extraction pump 226 and the inlet / outlet pipe rack 225 inject the rainwater from the collection trough into the inside of the separation buffer box 201. When the rainwater enters the separation buffer box 201, it first comes into contact with the separation mesh plate 203 and the slag discharge mesh plate 302. The two sets of mesh plates intercept larger impurities in the rainwater. The intercepted and filtered rainwater flows through the separation mesh plate 203 and the slag discharge mesh plate 302 to the pressurized treatment pipe 222 at the position of the isolation partition 202 in the separation buffer box 201. The pressurized treatment pipe 222 is opened by the limiting valve 244, and the rainwater enters the position of the staggered inclined baffle 205 between the separation buffer box 201 and the isolation partition 202, achieving preliminary interception and isolation and preliminary water inlet treatment.

[0088] At this time, the pusher rail 210 drives the pusher plate 211 to move along the feeding box 209 and into the inside of the feeding pipe 208. Then, the limiting valve 244 opens the feeding pipes 208 one by one according to the water flow speed, allowing the flocculant to be fed into the storage tank 206 along the feeding box 209 and the feeding pipes 208. Simultaneously, the drive motor 241 and belt drive box 240 drive the mixing scraper 207 to rotate, and the mixing scraper 207 pushes the flocculant and rainwater to mix. The flocculant is pushed outward after contacting water. When the rainwater enters, an acute angle is formed between the staggered inclined baffle 205 at the top and bottom and the isolation partition 202. When the pollutant impacts the acute angle, the rainwater is blocked, forming a reverse impact and limiting the speed of rainwater drainage. When the rainwater flow rate decreases, the flocculant continues to mix with the rainwater, flocculating and intercepting impurities in the rainwater. As the water flow rate decreases, the impurities gradually settle downward with the rainwater and fall to the top of the opening and closing sealing plate 221, achieving preliminary flocculation treatment.

[0089] Rainwater flows through the gap between the two staggered inclined baffles 205 and enters the next storage tank 206, repeating the upward operation. Through continuous stirring and continuous interception and deceleration, impurities generated by flocculation are gradually intercepted and precipitated. Continuous slag removal is achieved through multi-stage interception and deceleration, stirring and mixing, and slag scraping. During slag removal, the opening and closing motor 220 drives the opening and closing sealing plate 221 to rotate, opening the slag discharge hopper 204. Impurities fall into the slag discharge hopper 204 along the separating buffer box 201. Inside, after the slag discharge is completed, the opening and closing motor 220 drives the opening and closing sealing plate 221 to rotate and reset, thereby sealing and isolating the partition buffer box 201 and the slag discharge treatment hopper 204. This allows for continuous purification treatment through continuous interception flocculation and continuous slag removal during precipitation treatment. The treatment motor 323 and the bidirectional screw 324 drive the slag cleaning plate 325 to move along the storage screen 206. The slag cleaning plate 325 scrapes the side of the storage screen 206 to achieve slag cleaning and ensure continuous flocculation and mixing treatment.

[0090] As the rainwater rises along the isolation partition 202, the inclined limit reverse plate 212 performs contact backflushing treatment on the rising rainwater. The rainwater collides and decelerates again, and under the action of deceleration and gravity, impurities are decelerated and fall off again, achieving multi-stage continuous slag removal treatment. Through flocculation sedimentation and deceleration settling, the impurities in the rainwater are initially removed, achieving preliminary purification. The water enters the contact backflushing plate 213 on the top of the inner side of the partition buffer box 201 along the isolation partition 202. At this time, the water impacts the contact backflushing plate 213. When the water comes into contact with the contact backflushing plate 213, it is discharged outwards and collides with the incoming water, achieving deceleration again. At the same time, the arc-shaped structure of the contact backflushing plate 213 is used to achieve continuous backflushing, thereby fully decelerating, flocculating and slag removal treatment.

[0091] The electric push rod 216 drives the swing frame 215 to move back and forth. The swing frame 215 drives the internal reversing block 214 to move synchronously. The internal reversing block 214 drives the contact counter-impact plate 213 to rotate. The contact counter-impact plate 213 drives the internal water to swing continuously, realizing the slag removal process. The slag discharge electric slide rail 217 drives the slag cleaning scraper 218 to move along the isolation partition 202, pushing the impurities along the isolation partition 202 and the separation buffer box 201 to the slag discharge treatment pipe 219. The slag discharge treatment pipe 219 is opened by the limiting valve 244, and the impurities are discharged downward along the slag discharge treatment pipe 219 to the inside of the screening treatment box 309. The counter-impact deceleration, swing slag removal, swing deceleration and interception downward discharge are coordinated to realize the secondary slag discharge restriction.

[0092] The treated water flows to the position of the porous exhaust pipe frame 223. Air is introduced into the partition buffer tank 201 by the air pump 224 and the porous exhaust pipe frame 223. Continuous aeration is used to dissolve air in the water to form small bubbles, which release unwanted gases and volatile substances in the water into the air, realizing the treatment of volatile sludge. Continuous aeration also pushes the suspended impurities in the water to the surface. The connecting electric push rod 305 drives the connecting block 306 to move down, placing the sludge cleaning screen box 307 inside the partition buffer tank 201. The swing motor 308 drives the sludge cleaning screen box 307 to rotate along the connecting block 306. The sludge cleaning screen box 307 is used to concentrate and remove the impurities that rise during aeration. After the sludge removal is completed, the extraction pump 226 and the inlet and outlet pipe frame 225 extract the treated water in the partition buffer tank 201 and inject the treated water into the inside of the dual-chamber segmented tank 227 to realize the drainage treatment.

[0093] When the treated water is injected into the inner side of the dual-chamber segmented tank 227, the centrifugal mixing rack 233 and the centrifugal feeding tray 234 are rotated by the drive motor 241 and the multi-axis gearbox 232. The multi-axis gearbox 232 is used to change the speed of the centrifugal mixing rack 233 and the centrifugal feeding tray 234. The centrifugal mixing rack 233 drives the treated water to be centrifugally mixed. The multi-axis gearbox 232 drives the push linkage plate 235 to rotate along the storage fixed tank 236. The multi-axis gearbox 232 is used to change the speed of the push linkage plate 235, so that the push linkage plate 235 and the centrifugal mixing rack 233 always maintain a fixed speed difference ratio, so as to achieve uniform coordination of the mixing and feeding speeds. The push linkage plate 235 pushes the flocculant and organic matter absorbent in the storage fixed tank 236 to be placed on the top of the centrifugal feeding tray 234 along the feeding pipe 237. Centrifugation is used to centrifuge and throw out the treated material, so that the treated material is fully mixed with the treated water. Through stirring and centrifugation, the mixing and slag removal are carried out simultaneously during water treatment.

[0094] By opening the external discharge feed pipe 238 through the limiting valve 244, the mixed water is injected into another chamber of the dual-chamber segmented tank 227. The water flows along the dual-chamber segmented tank 227. At this time, the water gradually comes into contact with multiple sets of interception screens 228. The interception screens 228 intercept and treat impurities in the water flow. With the help of the cleaning electric slide rail 229, the cleaning sliding plate 230 pushes the impurities on the surface of the interception screens 228, and the impurities are brushed off and fall to the bottom of the inner side of the dual-chamber segmented tank 227, realizing continuous slag separation treatment. The treated water is injected into the inner side of the centralized reaction tank 239 through the external discharge feed pipe 238. The drive motor 241 and the belt drive box 240 drive the mixing multi-hole frame 242 to drive the water to rotate. The feeding pipe frame 243 and the extraction pump 226 extract the sterilization and bleaching mixture and discharge the mixture outward through the feeding pipe frame 243 and the mixing multi-hole frame 242. Sterilization and bleaching treatment are achieved through stirring and multi-position liquid injection.

[0095] The separated impurities are discharged into the screening box 309 through the slag discharge pipe 219 opened by the limiting valve 244. The impurity mixture at the location of the isolation partition 202 and the slag discharge hopper 204 is discharged into the inner side of the screening box 309. The cleaning and discharge fixing pipe 231 is opened by the limiting valve 244, and the impurity mixture in the double-chamber segmented box 227 is discharged into the inner side of the bottom mesh collection box 311 inside the screening box 309, realizing internal slag discharge and centralized collection and treatment. The slag discharge electric push rod 301 drives the slag discharge mesh plate 302 to move along the partition buffer box 201. The pressure sealing electric push rod 303 drives the pressure sealing integrated plate 304 to open the partition buffer box 201, thereby pushing the accumulated impurities outward and discharging them, realizing slag cleaning treatment. After the treatment is completed, the slag discharge electric push rod 301 and the pressure sealing electric push rod 303 drive the slag discharge mesh plate 302 and the pressure sealing integrated plate 304 to reset, realizing continuous slag cleaning and treatment.

[0096] The alignment electric actuator 314 drives the electromagnetic limit plate 315 to push the top of the vibrating screen plate 316 to fit against the bottom of the elastic screen plate 312. The alignment electric actuator 314 also moves the vibrating screen plate 316 to achieve position switching. The vibration pump 317 and spring reset rod 313 drive the vibrating screen plate 316 to vibrate the elastic screen plate 312, separating impurities and water in the mixture through vibration, achieving further dehydration. The water then flows downwards through the side of the bottom screen collection box 311 and the multi-port drain rack 310 into the screening process. Inside the box 309, further dehydration and collection are achieved. The sealing combination plate 320 is moved along the downward pressure separating plate 318 by the sealed electric slide rail 319. The downward pressure separating plate 318 is moved down along the screening box 309 and the bottom mesh collection box 311 by the downward pressure hydraulic cylinder 326, pushing the impurities down. Through the pressure treatment, secondary dehydration treatment is achieved, improving the water recovery rate. With the help of the linkage valve 322, the outgoing fixed pipe 321 is opened to discharge the water from the separation point for repeated treatment, thereby improving the efficiency of rainwater recovery.
