Description

Technical Field

[0001] The present invention relates to the field of rainwater treatment, and in particular to a staged rainwater intelligent interception and treatment device. Background Art

[0002] The existing initial rainwater intelligent interception and treatment device detects the suspended solids concentration in the rainwater through an SS detector, and compares the detected suspended solids concentration in the rainwater with the standard rainwater SS content, and discharges rainwater with different SS contents into different treatment channels. When the SS content in the rainwater is lower than the discharge standard, the solid waste in the water is removed and the rainwater is discharged normally. When the SS content in the rainwater is within 2 times of the discharge standard, the solid waste in the water is removed and the rainwater quality is purified and discharged into the river. When the SS content in the rainwater is higher than 2-3 times the discharge amount, the solid waste in the water is removed and the sewage is discharged into the treatment plant.

[0003] In the process of cleaning solid waste in rainwater, the solid waste is usually intercepted by crushing grids. In the subsequent process of intercepting rainwater, the residual solid waste accumulated previously will be broken up and mixed into the subsequent diversion and purification layers under the long-term water flushing, increasing the purification burden. At the same time, too much fixed waste accumulation can easily lead to grid blockage at the filter, affecting the rainwater transmission and circulation rate. For this reason, we propose a staged rainwater intelligent interception and treatment device. Summary of the Invention

[0007] A further improvement of the present invention is that a holding ring is provided inside the pushing box, and the two sides of the holding ring are arc-shaped, and arc-shaped slide grooves are provided inside the two sides of the holding ring. A linkage ball is installed in the middle of the holding ring, and the linkage ball is restricted by the holding ring and can rotate freely inside the holding ring. One side of the linkage ball is connected to a wheel disc cone, and sliding blocks are installed at both ends of the wheel disc cone. The sliding block is installed on the surface of the arc-shaped slide groove, and one side of the holding ring is connected to two concave arc grooves in opposite positions. A rotating motor is installed between the two concave arc grooves, and a rotating rod of the rotating motor is connected to a rotating part, and the rotating part is rotatably connected to the bottom of the wheel disc cone. Two connecting rods are installed at the bottom of the wheel disc cone, and a push block is installed at the bottom of the connecting rod, and the push block can slide inside the concave arc groove, and the push block and the flexible filter screen of the collecting port are connected to each other.

[0008] A further improvement of the present invention is that a first diverter box, a second diverter box, a third diverter box and a test area are provided inside the diverter element, the test area is located in the middle of the diverter element, a first pipe mouth is installed on one side of the first diverter box, a second pipe mouth is installed on one side of the second diverter box, and a third pipe mouth is installed on one side of the third diverter box. A second gate valve is installed at the connection between the test area and the first diverter box, the connection between the test area and the second diverter box, and the connection between the test area and the third diverter box.

[0009] A further improvement of the present invention is that circulation pipes in an "X" distribution are installed at both ends of the mixing block, and the circulation pipes are installed through the inside of the mixing block. The other end of the circulation pipe is connected to the restriction plate corresponding to its position. The mixing blocks are connected to each other through a connecting pipe, and two filter plates corresponding to each other are installed at the bottom of the mixing block. The filter plates are rotatably connected to the side of the connecting pipe, and the two filter plates are installed in a "V" shape corresponding to each other. A filter plate is installed at the connection between the mixing block and the circulation pipe.

[0010] A further improvement of the present invention is that an extension pipe is installed on the bottom of the connecting pipe, an SS detector is installed on the surface of the extension pipe, the extension pipe is located in the test area inside the diverter, a mud and debris port is installed on the bottom of the extension pipe, and a horizontal extension pipe is also installed on the bottom of the extension pipe, and a valve is installed at the connection between the horizontal extension pipe and the longitudinal extension pipe.

[0011] A further improvement of the present invention is that a filter material is installed inside the second diversion box, and the filter material includes but is not limited to an activated carbon layer and a quartz sand layer.

[0012] A further improvement of the present invention is that the steps of using the device are as follows:

[0013] In step 1, after the rainwater is collected by the collection port, the collection port filters out solid garbage particles and the like in the rainwater. The preliminarily filtered rainwater will move from the bottom of the collection port to the surface of the rotary disk and be restricted by the restriction plate set on the surface of the rotary disk. When the rainwater moves to the connection between the circulation pipe and the restriction plate, part of the rainwater will be transferred from the inside of the circulation pipe to the inside of the distribution block and will be moved out from the inside of the downward inclined circulation pipe. In the process of rainwater transfer, small particles of garbage will be intercepted by the filter sheet and the filter plate, and the filtered rainwater will flow out from the inside of the inclined circulation pipe and the connecting pipe. The rainwater flowing from the circulation pipe to the rotary disk will pass through the next distribution block for filtration again in the subsequent process. During the filtration process, the valve installed at the connection between the horizontal extension pipe and the longitudinal extension pipe inside the diverter is opened. At this time, the rainwater will flow from the horizontal extension pipe to the inside of the test area;

[0014] In step 2, when the solid particles and garbage accumulated inside the treatment port to be filtered out are too much, the rotating motor is used to drive the rotating part to rotate. During the rotation process, the rotating part drives the wheel cone to swing, and at the same time drives the linkage ball to rotate. During the swinging process, the wheel cone causes the sliding block to slide on the surface of the arc chute. The swinging wheel cone drives the push block to move inside the concave arc groove. Since the push block and the flexible filter are connected to each other, the first gate valve is opened, so that the garbage in the treatment port is pushed into the stacking box by the push block, thereby collecting the solid garbage;

[0015] Step 3: When the rainwater that has undergone secondary filtration is collected in the test area, the SS detector in the test area detects the SS content in the rainwater and diverts the rainwater by opening different second gate valves. When the SS content in the rainwater is more than twice the discharge standard, the rainwater is transferred to the first diversion box and transported to the sewage treatment plant through the first pipe outlet for treatment. When the SS content in the rainwater is within twice the discharge standard, the rainwater is moved to the second diversion box, filtered and purified, and then discharged into the river through the second pipe outlet. When the SS content in the rainwater is lower than the discharge standard, the rainwater is directly discharged through the third pipe outlet.

[0016] Step 4. During the secondary filtration of rainwater, the accumulated fine garbage will accumulate on the filter plate. At this time, you only need to close the valve installed at the connection between the horizontal extension pipe and the vertical extension pipe inside the diverter, and rotate the filter plate outward to release the accumulated fine particles of garbage to the mud and debris port.

[0017] 1. Compared with the prior art, the rainwater can be preliminarily filtered by the collection port, flexible filter screen and holding ring, and the garbage accumulated after the preliminary filtration can be collected, which is convenient for timely unified treatment of garbage during the filtration process, reducing the situation where subsequent garbage accumulation is impacted and broken by rainwater and mixed into subsequent diversion, reducing the subsequent purification burden, and when the solid particles filtered out inside the treatment port and the garbage accumulate too much, the rotating motor drives the rotating part to rotate. During the rotation process, the rotating part drives the wheel cone to swing and drives the linkage ball to rotate at the same time. During the swinging process, the wheel cone will make the sliding block slide on the surface of the arc chute, and the swinging wheel cone will drive the push block to move inside the concave arc groove. Since the push block and the flexible filter screen are connected to each other, the first gate valve is opened, and the garbage in the treatment port will be pushed into the stacking box under the action of the push block.

[0018] 2. Compared with the existing technology, the rotating disk and the mixing block are provided to realize the circulation and filtration of rainwater, and intercept small-volume broken garbage and small-particle solid garbage. The different inclination angles of the circulation pipe are combined with the rotating disk to guide the rainwater, so that the rainwater can be circulated and filtered multiple times, thereby improving the filtration efficiency. The preliminarily filtered rainwater will move from the bottom of the collection port to the surface of the rotating disk and be restricted by the restriction plate provided on the surface of the rotating disk. When the rainwater moves to the connection between the circulation pipe and the restriction plate, part of the rainwater will be transferred from the inside of the circulation pipe to the inside of the mixing block, and will be moved out from the inside of the downward-inclined circulation pipe. In the process of rainwater transfer, small particles of garbage will be intercepted by the filter sheets and the filter plates, and the filtered rainwater will flow out from the inside of the inclined circulation pipe and the connecting pipe. The rainwater flowing from the circulation pipe to the turntable will pass through the next mixing block for filtration again in the subsequent process.

[0019] 3. Compared with the prior art, the provided extension pipe and the transverse extension pipe installed at the bottom cooperate with each other to collect the gathered fine garbage, facilitate the unified treatment of the fine garbage, and enable the rainwater transmitted from the circulation pipe to be directly moved from the transverse extension pipe to the test area. In the process of secondary circulation and filtration of the rainwater, the accumulated fine garbage will accumulate on the filter plate. At this time, it is only necessary to close the valve installed at the connection between the transverse extension pipe and the longitudinal extension pipe inside the diverter and rotate the filter plate outward to release the accumulated fine particles of garbage to the mud and debris port. During the filtration process, the valve installed at the connection between the transverse extension pipe and the longitudinal extension pipe inside the diverter is opened. At this time, the rainwater passing through the filter plate will flow from the transverse extension pipe to the inside of the test area. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Through this embodiment, it can be achieved that: the provided extension pipe 16 and the horizontal extension pipe 16 installed at the bottom cooperate with each other to collect the gathered small garbage, facilitate the unified treatment of the small garbage, and enable the rainwater transmitted from the circulation pipe 13 to be directly moved from the horizontal extension pipe 16 to the test area 34. In the process of circulating the rainwater for secondary filtration, the accumulated small garbage will accumulate on the filter plate 28. At this time, it is only necessary to close the valve installed at the connection between the horizontal extension pipe 16 and the longitudinal extension pipe 16 inside the diverter 6 and rotate the filter plate 28 outward to release the accumulated small particle garbage to the mud debris port 7; in the process of filtering, open the valve installed at the connection between the horizontal extension pipe 16 and the longitudinal extension pipe 16 inside the diverter 6 Valve.

When the SS content in the rainwater is more than twice the discharge standard, the rainwater is transferred to the first diversion box 30 and transported to the sewage treatment plant through the first pipe port 8 for treatment. When the SS content in the rainwater is within twice the discharge standard, the rainwater is moved to the inside of the second diversion box 31 and filtered and purified before being discharged into the river from the second pipe port 9. When the SS content in the rainwater is lower than the discharge standard, the rainwater is directly discharged from the third pipe port 10.

[0048] It should be noted that the present invention is a stage-type intelligent rainwater interception and treatment device. When in use, in step one, after the rainwater is collected by the collection port 2, the collection port 2 filters out solid garbage particles and the like in the rainwater. The preliminarily filtered rainwater will move from the bottom of the collection port 2 to the surface of the turntable 14 and be restricted by the restriction plate 15 provided on the surface of the turntable 14. When the rainwater moves to the connection between the circulation pipe 13 and the restriction plate 15, part of the rainwater will be transferred from the inside of the circulation pipe 13 to the inside of the mixing block 11, and will be moved out from the inside of the downward-sloping circulation pipe 13. In the process of rainwater transfer, small particles of garbage will be intercepted by the filter sheet 29 and the filter plate 28, and the filtered rainwater will be It will flow out from the inside of the inclined circulation pipe 13 and the connecting pipe 12. The rainwater flowing from the circulation pipe 13 to the rotary disk 14 will be filtered again through the next allocation block 11 in the subsequent process. During the filtering process, the valve installed at the connection between the horizontal extension pipe 16 and the longitudinal extension pipe 16 inside the diverter 6 is opened. At this time, the rainwater will flow from the horizontal extension pipe 16 to the inside of the test area 34. When the solid particles and garbage accumulated inside the treatment port are too much, the rotating part 26 is driven to rotate by the rotating motor. During the rotation process, the rotating part 26 drives the wheel cone 19 to swing and drives the linkage ball 20 to rotate. The wheel cone 19 swings During the process, the sliding block 22 will slide on the surface of the arc chute 21, and the swinging wheel cone 19 will drive the pushing block 25 to move inside the concave arc groove 24. Since the pushing block 25 and the flexible filter screen 27 are connected to each other, the first gate valve 17 is opened, so that the garbage in the treatment port is pushed into the stacking box 3 under the action of the pushing block 25, thereby collecting the solid garbage. When the rainwater after the secondary filtration is gathered into the test area 34, the SS detector 33 inside the test area 34 detects the SS content in the rainwater, and diverts the rainwater by opening different second gate valves 35. When the SS content in the rainwater is more than twice the discharge standard, the rainwater is transferred to the first diversion area 34. The rainwater flows through the flow box 30 and is transported to the sewage treatment plant for treatment through the first pipe port 8. When the SS content in the rainwater is within twice the discharge standard, the rainwater is moved to the inside of the second diversion box 31 and filtered and purified before being discharged from the second pipe port 9 to the river. When the SS content in the rainwater is lower than the discharge standard, the rainwater is directly discharged from the third pipe port 10. In the process of circulating the rainwater for secondary filtration, the accumulated fine garbage will accumulate on the filter plate 28. At this time, it is only necessary to close the valve installed at the connection between the horizontal extension pipe 16 and the longitudinal extension pipe 16 inside the diversion member 6, and rotate the filter plate 28 outward to release the accumulated fine particles of garbage to the mud and debris port 7.

6. A staged rainwater intelligent interception and treatment device according to any one of claims 1 to 5, characterized in that: The steps for using the device are as follows: Step 1: After the rainwater is collected by the collection port (2), the collection port (2) filters out the solid garbage particles in the rainwater. The initially filtered rainwater moves from the bottom of the collection port (2) to the surface of the rotary disk (14) and is restricted by the restriction plate (15) provided on the surface of the rotary disk (14). When the rainwater moves to the connection between the circulation pipe (13) and the restriction plate (15), part of the rainwater is transferred from the inside of the circulation pipe (13) to the inside of the mixing block (11), and is removed from the inside of the downwardly inclined circulation pipe (13). In the process of rainwater transfer, small particles The garbage will be intercepted by the filter sheet (29) and the filter plate (28), and the filtered rainwater will flow out from the inclined circulation pipe (13) and the connecting pipe (12). The rainwater flowing from the circulation pipe (13) to the rotary disk (14) will be filtered again by the next allocation block (11) in the subsequent process. During the filtering process, the valve installed at the connection between the horizontal extension pipe (16) and the longitudinal extension pipe (16) inside the diverter (6) is opened. At this time, the rainwater will flow from the horizontal extension pipe (16) to the inside of the test area (34); Step 2: When the solid particles and garbage that have been filtered out and accumulated inside the treatment port are too much, the rotating member (26) is driven to rotate by the rotating motor. During the rotation process, the rotating member (26) drives the wheel cone (19) to swing and drives the linkage ball (20) to rotate. During the swing process, the wheel cone (19) causes the sliding block (22) to slide on the surface of the arc chute (21). The swinging wheel cone (19) drives the push block (25) to move inside the concave arc groove (24). Since the push block (25) and the flexible filter screen (27) are connected to each other, the first gate valve (17) is opened, so that the garbage in the treatment port is pushed into the accumulation box (3) under the action of the push block (25), thereby collecting the solid garbage; Step 3: When the rainwater after secondary filtration is collected in the test area (34), the SS detector (33) in the test area (34) detects the SS content in the rainwater, and diverts the rainwater by opening different second gate valves (35). When the SS content in the rainwater is more than twice the discharge standard, the rainwater is transferred to the first diversion box (30) and transported to the sewage treatment plant through the first pipe port (8) for treatment. When the SS content in the rainwater is within twice the discharge standard, the rainwater is moved to the second diversion box (31) and filtered and purified before being discharged to the river from the second pipe port (9). When the SS content in the rainwater is lower than the discharge standard, the rainwater is directly discharged from the third pipe port (10). Step 4: During the process of recycling and filtering the rainwater for the second time, the accumulated fine garbage will accumulate on the filter plate (28). At this time, it is only necessary to close the valve installed at the connection between the horizontal extension pipe (16) and the longitudinal extension pipe (16) inside the diverter (6), and rotate the filter plate (28) outward to release the accumulated fine particles of garbage to the mud and debris port (7).
