Description

TECHNICAL FIELD

[0001] The present application relates to the sewage treatment technical field, especially to a sewage reuse equipment for water ecological environment management. BACKGROUND

[0002] In the sewage reuse project in the process of water ecological environment management, ecological filter bed and artificial wetland and other technologies are playing an increasingly important role. The purpose of such technologies is to purify domestic sewage or runoff rainwater to the standard of reuse for greening, landscape or miscellaneous use. The system first filters domestic garbage in water through the filter bed structure, and intercepts and degrades suspended solids in water. Then the water in the filter bed is further purified and filtered through the reuse equipment, and then put into use. However, the water body of the ecological filter bed also carries part of the solid suspended matter, including a large amount of aquatic plants and fallen leaves. Such flexible fibrous impurities pose a serious threat to the stable operation of the reuse equipment. In addition to easily causing the blockage of the filter parts, they will also rot and decompose in the long-term humid environment, thereby causing secondary pollution to the water quality purified by the ecological filter bed, and increasing the burden of subsequent sewage purification operation. Therefore, it is necessary to regularly remove this part of flexible fibrous impurities.

[0003] The current sewage reuse equipment uses dense grids to intercept flexible fibrous impurities, and then regularly removes and destroys them. However, flexible fibrous impurities will absorb a lot of water when soaked in water, especially aquatic plants such as water grass and algae. Due to the particularity of the ecological filter bed, these aquatic plants not only account for a large part of the flexible fibrous impurities, but also have a water content of 70% to 90% of their fresh weight according to the type of aquatic plants. If these water and flexible fibrous impurities are removed together from the reuse equipment, it will not only cause waste of water resources and reduce the sewage reuse rate, but also increase the difficulty of destroying the water grass for the staff and increase the transportation burden. In view of this, we propose a sewage reuse equipment for water ecological environment management. SUMMARY

[0016] The following will describe in detail, with reference to the accompanying drawings of the embodiments of the present invention, a wastewater reuse device for water ecological environment treatment according to the present invention. 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.

[0017] like Figures 1-10 As shown, the present invention provides a wastewater reuse device for water ecological environment treatment, including a fixed base 10, on which a filter pipe 20 is inclinedly fixed. A filter mechanism 30 and a drive mechanism 40 are installed inside the filter pipe 20. A bend is provided inside the filter pipe 20 relative to the upper part of the filter mechanism 30, which reduces the force of water flow. The filter mechanism 30 includes a sleeve 31 fixedly connected to the output end of the drive mechanism 40. A vertical plate 33 is slidably installed inside the sleeve 31, and a filter plate 32 is fixedly installed at the lower end of the vertical plate 33. A drain outlet 21 is opened on the bottom surface of the filter pipe 20. The vertical plate 33 and the drain outlet 21 are staggered. A sealing plate 22 is slidably connected inside the drain outlet 21, and two symmetrically slidably connected... A movable block 221 has an insert block 223 hinged to its inner end via a torsion spring 222. The sleeve 31 has a side groove 312 on its side wall that presses against the insert block 223. When the sleeve 31 descends, it presses against the top surface of the insert block 223 from its bottom surface, causing it to deflect downwards. When the sleeve 31 rises, it presses against the bottom surface of the insert block 223 from its bottom surface via the side groove 312, causing the sealing plate 22 to rise. A flow-blocking mechanism 50 is installed inside the sleeve 31. The flow-blocking mechanism 50 includes two rotating plates 51 that are symmetrically rotatably connected inside the sleeve 31. A support plate 53 is rotatably connected inside the sleeve 31. When the support plate 53 flips up, it can lift the two rotating plates 51, closing the upper opening of the sleeve 31. When the lifted rotating plates 51 descend, they cooperate with the filter plate 32 to squeeze the water plants on the filter plate 32 dry.

[0018] Multiple insertion rods 24 are uniformly fixed inside the lower side of the filter tube 20, which are inserted into the holes on the filter plate 32. The number of insertion rods 24 is the same as the number of holes on the filter plate 32 and they are arranged in a one-to-one correspondence. The lower ends of each row of insertion rods 24 are connected by a crossbar and fixed to the inner wall of the filter tube 20. The height of the insertion rods 24 is slightly higher than the height of the holes on the filter plate 32. The bottom surface of the insertion block 223 is an arc structure. The insertion block 223 is slidably connected to the inner wall of the filter tube 20. The inner wall of the filter tube 20 is provided with a groove for the insertion block 223 to slide up and down. The filter plate 32 is provided with a through groove 321 corresponding to the position of the insertion block 223. The through groove 321 is located outside the vertical plate 33. The whole device is set in an inclined position. Under the action of gravity, the flexible fiber debris will move towards the drain outlet 21. Therefore, the flexible fiber debris will not come into contact with the through groove 321.

[0019] The movable block 221 is elastically connected to the sealing plate 22. The end of the movable block 221 away from the sleeve 31 is L-shaped. The sealing plate 22 has a groove that is slidably connected to the movable block 221. The end of this groove away from the sleeve 31 is circular. A tension spring 224 is fixed between the L-shaped end of the sleeve 31 and the inner wall of the groove. A circular groove 23 is opened in the side wall interlayer of the filter tube 20. When the movable block 221 rises to its maximum height, it corresponds to the circular groove 23. A storage box 11 is slidably installed on the fixed base 10 at the drain outlet 21. A groove is opened on the top surface of the fixed base 10 to limit the position of the storage box 11. The staff only needs to slide the storage box 11 along the groove to install it below the drain outlet 21, which facilitates the staff's transportation of flexible fiber debris.

[0020] A limiting plate 52 is fixedly provided between the two rotating plates 51 inside the sleeve 31. The limiting plate 52 has an arc-shaped structure, which is used to limit the rotation angle of the two rotating plates 51 so that they are supported and block the opening end of the sleeve 31 at a flat angle; it can also block the gap between the two rotating plates 51 to prevent flexible fiber debris from getting stuck and causing the rotating plates 51 to jam, and also to prevent the stuck debris from affecting the quality of the recycled water.

[0021] A protrusion is provided in the middle of the inner side wall of the rotating plate 51, which makes the two rotating plates 51 arranged in a figure-eight structure. A cavity 311 is opened in the sleeve 31. The support plate 53 is rotatably connected to the inside of the cavity 311. The support plate 53 is elastically connected to the inner wall of the cavity 311. A spring rod 54 is provided between the support plate 53 and the inner wall of the cavity 311. The spring rod 54 is rotatably connected to the inner wall of the cavity 311. A sliding seat 541 is rotatably connected to the end of the spring rod 54 near the support plate 53. The sliding seat 541 is slidably connected to the side wall of the support plate 53. When the spring rod 54 is not compressed, it can support the support plate 53 and lift the two rotating plates 51.

[0022] The sleeve 31 has a through opening 34 that is intersected and connected to the cavity 311. The vertical plate 33 has a vertical groove 331 in the middle that corresponds to the position of the cavity 311. Under normal conditions, the top surface of the vertical groove 331 presses against the top surface of the support plate 53, causing its end to rotate into the cavity 311.

[0023] The drive mechanism 40 includes a rotating shaft 41 rotatably connected to the filter tube 20. A servo motor 42 is coaxially fixedly connected to the lower end of the rotating shaft 41. The servo motor 42 is embedded in the bottom surface of one side of the filter tube 20. The lower end of the rotating shaft 41 is coaxially fixedly connected to its output end, and the output end of the servo motor 42 is rotatably connected to the filter tube 20 through a shaft seal. A movable ring 43 is slidably sleeved on the rotating shaft 41. A spiral groove 411 is opened on the rotating shaft 41. An extrusion block 431 that slides with the movable ring 43 is fixedly provided on the inner wall of the movable ring 43. The movable ring 43 is connected and fixedly connected to the side wall of the sleeve 31. The movable ring 43 is connected and fixedly connected to the side wall of the sleeve 31 near the top surface through two inclined plates. The movable ring 43 and the two inclined plates on it are slidably connected to the filter tube 20. Guide grooves are opened on the filter tube 20 at corresponding positions of the movable ring 43 and the inclined plates. Sliding sealing strips are provided at the contact positions between the movable ring 43 and the inclined plates and the inner wall of the guide grooves to prevent water from leaking from the guide grooves.

[0024] The servo motor 42 in this device is controlled by a PLC, and the following steps are performed: S1. Control the servo motor 42 to rotate a certain number of times in the first direction. The number of rotations must be consistent with the number of turns of the spiral groove 411 to ensure that the sleeve 31 can move smoothly to the bottom. S2. Stop after rotating a fixed number of times. The stopping time needs to be determined based on the proportion of aquatic plants in the recycled water. Avoid stopping for too long or too short a time to prevent the filter mechanism 30 from getting stuck or over-operating. S3. After the pause time ends, control the servo motor 42 to switch to the second rotation direction and rotate a specified number of times. This number of times is consistent with the number of times rotated in the first rotation direction, ensuring that the sleeve 31 can move smoothly to the uppermost position. S4. After completing the second rotation in the second direction, immediately repeat S1.

[0025] Working principle: The operator can connect the external water supply structure and the external water storage equipment to the upper and lower opening ends of this device through the flange. The water will flow through the bend inside the filter pipe 20 and enter the sleeve 31. At this time, the interception mechanism 50 is in the undeployed state. The water and the flexible fiber debris in it can enter the filter mechanism 30 and be intercepted by the filter plate 32. The separated liquid will pass through the filter plate 32 and the grid array formed by the multiple inserts 24 below it, and finally be discharged from the lower opening end of the filter pipe 20. The discharged liquid is the recycled water after solid-liquid separation.

[0026] In the initial state of this device, the servo motor 42 will first drive the filter mechanism 30 of this device to move up and down once, thereby clearing the debris in the filter mechanism 30. After the lifting and lowering is completed, the servo motor 42 will enter the stop phase. At this time, the water flow and the flexible fiber debris in it will enter the filter mechanism 30. The flexible fiber debris will then be trapped by the filter plate 32 in the space enclosed by it, the vertical plate 33 and the inner wall of the filter tube 20. After the stop phase ends, the servo motor 42 will drive the rotating shaft 41 to rotate along the first rotation direction. The spiral groove 411 on it will exert a squeezing effect on the squeezing block 431 on the inner wall of the moving ring 43. The squeezed squeezing block 431 will drive the moving ring 43 to descend. 43 will then drive the sleeve 31 to descend via the inclined plate. In the initial stage of descent, the filter plate 32 will be affected by gravity, and the accumulated aquatic plants and the large amount of water contained in the aquatic plants will provide a load. Therefore, the filter plate 32 and the vertical plate 33 will maintain a constant distance from the sleeve 31 under the action of gravity. During this process, the water flowing down from above will still flow from inside the sleeve 31. When the hole on it is connected to the insertion rod 24, under the obstruction of the grid structure formed by the insertion rod 24, the insertion rod 24 can push out the flexible fiber debris stuffed into the hole of the filter plate 32 and scrape the inner wall of the hole of the filter plate 32. At the same time, the filter plate 32 will stop descending, and the sleeve 31 will continue to descend and reduce the distance between itself and the filter plate 32.

[0027] After the distance between the two changes, the support plate 53 disengages from the top surface of the vertical groove 331, thus releasing the pressure of the vertical groove 331 on the support plate 53. The support plate 53 will flip up under the action of the two spring rods 54. The spring rods 54 will extend to their longest state without external force, thus they can squeeze into the gap between the two rotating plates 51 to support the two rotating plates 51. The lower end of the support plate 53 is set as an inverted triangular prism structure. This structure facilitates the gradual opening of the two rotating plates 51 and makes it easier to squeeze into the gap between the two rotating plates 51. Then the rotating plates 51 will close the opening end of the sleeve 31. At this time, although water continues to enter the device, its force is greatly reduced by the bending structure inside the filter tube 20. Therefore, the force of the water flow is far from enough to open the rotating plates 51.

[0028] As the sleeve 31 continues to descend, the bottom surfaces of the two rotating plates 51 will come into contact with the flexible fiber debris on the filter plate 32. The lower opening of the sleeve 31 is designed as a trumpet shape. With this design, the sleeve 31 can gather the flexible fiber debris on the filter plate 32 into the cavity formed by the sleeve, rotating plates 51 and filter plate 32. Then, as the rotating plates 51 and filter plate 32 approach each other, the flexible fiber debris will be gradually squeezed into blocks. The vertical plate 33 is slidably connected to the sleeve 31 through the through-hole 34, so its upper end can extend through the sleeve 31 to the top. In this way, the space between the rotating plates 51 and the filter plate 32 can be fully compressed, thereby fully compressing the flexible fiber debris and draining the water. The drained water will flow from the through-grooves 321 on both sides to the bottom of the filter plate 32.

[0029] After the servo motor 42 drives the rotating shaft 41 to rotate a specified number of times in the second rotation direction, the rotating shaft 41 will immediately return to the first rotation direction. Subsequently, the extrusion block 431 will move upward under the extrusion of the spiral groove 411, and will continue to drive the sleeve 31 to rise in the subsequent rotation of the rotating shaft 41. The flexible fiber debris block that has been squeezed dry by the rotating plate 51 and the filter plate 32 will stay on the filter plate 32.

[0030] Prior to this, during the descent of the sleeve 31, its bottom edge will make pressing contact with the top surface of the insert 223, causing the insert 223 to rotate downwards against the elastic force of the torsion spring 222. Subsequently, the outer wall of the sleeve 31 will continue to slide in contact with the top surface of the insert 223 after rotating 90 degrees downwards. Under the restriction of the sleeve 31, the insert 223 remains in this state and cannot rebound. When the insert 223 aligns with the side groove 312, the torsion spring 222 will drive the insert 223 to reset. If the sleeve 31 is in the descent state at this time, the insert 223 will be quickly pressed down and rotated again by the top surface of the side groove 312 after resetting. If the sleeve 31 is in the descent state at this time, the insert 223 will be pressed down and rotated again by the top surface of the side groove 312 after resetting. When the device is in the rising state, the bottom surface of the side groove 312 will press the bottom surface of the insert 223. Although the insert 223 is slidably connected to the sealing plate 22, its outer end is restricted by the inner wall of the filter tube 20. Therefore, it can only rise with the sleeve 31 and drive the sealing plate 22 to rise together to open the drain outlet 21. The top surface of the sleeve 31 is always higher than the top surface of the drain outlet 21 throughout the operation of this device. Therefore, the insert 223 will not correspond to the top surface of the sleeve 31. Moreover, the upper and lower sides of the sleeve 31 are not connected before and after the drain outlet 21 is opened, and the water flow above the sleeve 31 cannot flow out from the drain outlet 21.

[0031] In the initial stage of ascent, the sleeve 31 and the filter plate 32 gradually move away from each other. Then, a channel for flexible fiber debris to pass through is opened between the bottom surface of the sleeve 31 and the filter plate 32. The top surface of the filter plate 32 is higher than the bottom surface of the inner end of the drain port 21, and the filter tube 20 is in an inclined state. Gravity will also cause the flexible fiber debris block to tend to move towards the drain port 21. Therefore, when the bottom surface of the sleeve 31 is higher than the top surface of the flexible fiber debris that has been compressed into a block, the debris block will slide out of the device from the drain port 21 and then fall into the storage box 11.

[0032] When the sleeve 31 moves the insert block 223 to the circular groove 23, the bottom surface of the side groove 312 will press the rounded corner of the bottom surface of the insert block 223, causing the insert block 223 to drive the movable block 221 to slide into the circular groove 23 against the force of the tension spring 224. As a result, the upward force of the sleeve 31 will no longer act on the insert block 223, and the sealing plate 22 will no longer rise. During the process of the insert block 223 being pressed into the circular groove 23, this action can cause the sleeve 31 to vibrate under the action of inertia, and other structures connected to it will also shake synchronously, which can be used to promote the accelerated discharge of debris blocks. When the bottom surface of the sleeve 31 is higher than the position of the circular groove 23, the end of the insert block 223 is no longer restricted by the sleeve 31, and it and the movable block 221 will reset under the contraction of the tension spring 224. Then, under the action of gravity, the sealing plate 22 will fall down and re-close the drain port 21. Since the rotating plate 51 that presses the flexible fiber debris block is located inside the sleeve 31, the height of the debris block is much lower than the height of the sleeve 31. Therefore, the drain port 21 will close before the two rotating plates 51 reopen the water passage. At the same time, this design also provides sufficient time for the flexible fiber debris block to slide out of the filter tube 20. As the sleeve 31 continues to move upward, the sealing plate 22 will first block the drain outlet 21, and the filter plate 32 will be lifted by the sleeve 31 through the vertical plate 33. During the lifting and lowering process, the insert block 223 will pass through the filter plate 32 through the through groove 321, so it will not affect the operation of the filter plate 32. At the same time, the top surface of the vertical groove 331 will press against the top surface of the support plate 53 again, and the weight of the vertical plate 33 and the filter plate 32 will press the support plate 53 back into the cavity 311, so that the support plate 53 no longer supports the rotating plate 51. Then the rotating plate 51 rotates downward under the action of gravity, and the opening end of the sleeve 31 is opened again. Then the recycled water can continue to pass through the filter plate 32 for solid-liquid separation.
