Description

Technical Field

[0001] The invention relates to the technical field of drainage devices, and in particular to an automatic water supply and drainage device for municipal use. Background Art

[0002] Water supply and drainage is the general term for the facilities that provide water and wastewater for people's lives, production, municipal administration and fire protection. It supplies water quantities and water quality that meet different needs to various categories of users. At the same time, it is responsible for the collection, transportation and treatment of wastewater discharged by users, so as to eliminate the pollutants in the wastewater that are harmful to human health and protect the environment.

[0003] A sedimentation well generally refers to a well-shaped drainage facility located at the intersection of drainage pipes and drainage ditches within the station, at the transition point of drainage pipes or at places where elevation changes, etc., which are prone to siltation and blockage, to facilitate silt removal and sedimentation.

[0004] Sedimentation wells need to be cleaned regularly after the sediment deposited inside is separated from the water. During the cleaning process of existing sedimentation wells, the sludge at the bottom is often brought out as a whole through a hanging basket, or salvaged with the help of a salvage basket. However, since the sedimentation well has a certain depth, during the salvage and cleaning process, the salvage basket needs to be extended to the bottom for cleaning, which is inconvenient to clean. If a hanging basket placed at the bottom of the sedimentation well is used and the whole is lifted and pulled, the space of the sedimentation well needs to be kept unobstructed, and a certain lifting and pulling force is required, which increases the difficulty of cleaning.

[0005] Based on this, the present invention designs a municipal automatic water supply and drainage device to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide an automatic water supply and drainage device for municipal use, so as to solve the problem raised in the above-mentioned background technology that since the sedimentation well has a certain depth, during the process of salvaging and cleaning, it is necessary to extend the salvage basket to the bottom for cleaning, which is inconvenient for cleaning. If a hanging basket placed at the bottom of the sedimentation well is used and the whole is hoisted, it is necessary to keep the sedimentation well space unobstructed, and a certain hoisting force is required, which increases the difficulty of cleaning.

[0007] To achieve the above object, the present invention provides the following technical solution: a municipal automatic water supply and drainage device, comprising a sedimentation well, a water inlet pipe and a drainage pipe, the sedimentation well having a filter chamber connected to the water inlet pipe and a drainage chamber connected to the drainage pipe, the filter chamber and the drainage chamber are separated by a partition fixed in the sedimentation well, and further comprising:

[0008] A collecting tank, the collecting tank being movably plugged into the top of the partition of the sedimentation well;

[0009] A filter assembly, the filter assembly comprising a fixed filter element and a movable filter element, the fixed filter element having a fixed shell and a first filter surface and a second filter surface, the second filter surface surrounds and forms a through groove, the movable filter element is movably inserted in the through groove, and the fixed shell is fixedly connected to the bottom end of the filter chamber;

[0010] A height adjustment component, the height adjustment component is used to adjust the height of the movable filter element;

[0011] The vertical conveying component is used to vertically convey the filter residue in the movable filter element whose height is adjusted to the vertical conveying component to the collecting tank, so as to realize active cleaning and collection of sediment in the sedimentation well.

[0012] It should be understood that during the filtering process, the water discharged from the water inlet pipe will enter the filter cavity and flow to the first filter surface and the second filter surface. The first filter surface is fan-shaped and has a certain inclination. The filtered filter material will slide into the through groove and be collected by the movable filter element and precipitated in the movable filter element, thereby realizing the centralized collection of the filtered sediment. Then, the movable filter element is lifted by the height adjustment component until it is located at the vertical conveying component. In the process of lifting upward, the water in the movable filter element is drained. After reaching the vertical conveying component, the sediment in the movable filter element is vertically conveyed to the collection tank by the vertical conveying component.

[0013] During the entire collection process, the filtered sediment is actively cleaned away from the bottom of the sedimentation well and raised to a position close to the opening of the sedimentation well. During the cleaning process, there is no need to open the cover of the sedimentation well, which is convenient and quick. The active collection process is carried out in the sedimentation well. According to needs, a certain frequency of collection is adopted. On the one hand, it reduces the obstruction of sediment and is conducive to keeping the filter surface of the filter component unobstructed. On the other hand, it is conducive to avoiding excessive accumulation of sediment, causing agglomeration, and increasing the difficulty of cleaning.

[0014] It should be noted that when a sedimentation well needs to be cleaned, one only needs to open the well cover and take out the collection pool at the wellhead. There is no need to go deep into the bottom of the sedimentation well for salvage, which is convenient and quick.

[0015] As an optional technical solution of the present invention, the movable filter element includes:

[0016] An annular frame, the annular frame is slidably mounted in the through slot, and the height adjustment assembly is used to adjust the height of the annular frame;

[0017] A movable plate, wherein a flexible filter screen is fixedly connected between the edge of the movable plate and the inner ring surface of the annular frame to form a boss-type structure;

[0018] An elastic support member, wherein two ends of the elastic support member are respectively fixedly connected to the moving plate and the bottom of the sedimentation well to achieve support for the moving plate.

[0019] It should be understood that during the filtering process, the flexible filter net of the movable filter element will form an upwardly protruding state, forming a boss-type structure, so that the sediment filtered by the first filter surface slides onto the movable filter element, and after being filtered by the flexible filter net, it can slide along the inclined surface of the boss-type structure of the flexible filter net to the inner edge of the annular frame. During the filtering process of the movable filter element, under the action of gravity, the sediment always accumulates to the inner edge of the annular frame, reducing the obstruction of the flexible filter net, maintaining a certain fluidity, and keeping the sediment in the movable filter element at all times.

[0020] It should be further explained that if the flexible filter is quickly clogged, the water will be stirred in the ring frame and the sediment will be brought out. Therefore, it is necessary to maintain circulation and drain the water collected in the ring frame in time.

[0021] As an optional technical solution of the present invention, the elastic support member includes:

[0022] A support pipe, the support pipe is fixedly connected to the bottom surface of the sedimentation well;

[0023] A support rod, wherein the support rod is slidably connected to the inside of the support tube, and the top end of the support rod is fixedly connected to the bottom surface of the movable plate;

[0024] A support spring, wherein two ends of the support spring are respectively fixedly connected to the inner bottom surface of the support tube and the bottom end of the support rod.

[0025] It should be understood that under the support of the elastic support member, the support rod always maintains support for the movable plate, and the movable plate props up the flexible filter net to form a boss-type structure. Under the support of the elastic support member, when it is collided with sediment or impacted by water, it will also generate vibration, which is conducive to shaking and cleaning the sediment on the surface of the flexible filter net.

[0026] As an optional technical solution of the present invention, the vertical conveying assembly includes:

[0027] A fixed delivery pipe, wherein the fixed delivery pipe is fixedly mounted on the surface of the partition;

[0028] A movable conveying pipe, the movable conveying pipe is rotatably connected to the top of the fixed conveying pipe, and the side thereof is fixedly connected to a discharge pipe;

[0029] A fixed cover, the fixed cover is rotatably connected to the top end of the movable conveying pipe and is fixedly connected to the fixed conveying pipe via a connecting frame;

[0030] The second motor is fixedly installed on the top of the fixed cover, and the output end is fixedly connected with a conveying rod. The conveying rod passes through the fixed cover and then passes through the movable conveying pipe and the fixed conveying pipe in sequence until it extends to the bottom opening of the fixed conveying pipe. The surface of the conveying rod is fixedly connected with a spiral conveying blade.

[0031] Specifically, a feed port is provided at the bottom end of the surface of the fixed conveying pipe, so that the sediment can enter the fixed conveying pipe through the feed port.

[0032] It should be understood that when cleaning is required, the annular frame is raised by the height adjustment assembly until the movable plate is in tight contact with the bottom end of the fixed conveying pipe;

[0033] During the process of the annular frame being raised, the support spring first maintains the upward support for the movable plate. As the annular frame continues to move, the squeezing force on the support spring is gradually released until the flexible filter net begins to pull the movable plate. The flexible filter net will form a boss-type structure downward, and the sediment on the inner edge of the annular frame will begin to gather to the top of the movable plate until the bottom end of the fixed conveying pipe is tightly pressed against the top surface of the movable plate. This is conducive to concentrating the collected sediment to the bottom end of the fixed conveying pipe, preparing for vertical conveying, and facilitating thorough cleaning of the sediment collected in the movable filter element.

[0034] As a further optimized technical solution of the present invention, the top of the movable plate is rotatably connected with a turntable, the side of the turntable is connected with a scraper, and a driving component is connected between the top of the turntable and the conveying rod, and the scraper includes:

[0035] A connecting seat, the connecting seat is fixedly connected to the edge of the movable plate;

[0036] A scraper is rotatably connected to the connecting seat.

[0037] It should be understood that after the annular frame is raised, during the conveying process of the vertical conveying assembly, the second motor will drive the conveying rod to rotate, and the conveying rod will drive the turntable to rotate through the driving assembly, and the turntable will simultaneously drive the scraper to rotate, thereby scraping the inner surface of the boss-type structure formed by the downward protrusion, which is beneficial to remove the adhesion between the sediment and the flexible filter mesh surface, so that the sediment gathers to the bottom end of the fixed conveying pipe, which is beneficial to thoroughly clean the sediment in the movable filter element.

[0038] As a technical solution for further optimization of the present invention, the top of the connecting seat has a limiting end for limiting the upward flipping angle of the scraper.

[0039] It should be understood that by setting the limit end, the flipping angle of the scraper is limited. When the flexible filter is pulled downward and tightened, the scraper will be driven to flip upward. When a downward boss-type structure is formed, the scraper is attached to the surface of the flexible filter under the restriction of the limit end, preparing for subsequent scraping and cleaning.

[0040] As a technical solution further optimized by the present invention, the driving assembly includes a first magnetic block and a second magnetic block, the first magnetic block is fixedly connected to the top of the turntable, the second magnetic block is fixedly connected to the bottom of the conveying rod, and the surfaces of the first magnetic block and the second magnetic block are rough.

[0041] It should be understood that when the movable plate turntable approaches the bottom end of the conveying rod, the first magnetic block and the second magnetic block will generate attraction, and under the action of friction resistance, the rotation of the conveying rod will synchronously drive the rotation of the turntable, and then synchronously drive the rotation of the scraper to perform scraping and cleaning.

[0042] As a further optimized technical solution of the present invention, a temporary filtering component is also included, and the temporary filtering component includes:

[0043] A temporary filter cover, which is slidably sleeved on the surface of the support tube;

[0044] Two driving plates, the two driving plates are symmetrically fixedly connected to the bottom end of the inner wall of the temporary filter cover;

[0045] Two easing grooves are symmetrically arranged on the surface of the support tube, and the two driving plates are respectively passed through the two easing grooves and fixedly connected with the bottom end of the support rod surface.

[0046] It should be understood that when the movable filter element is lifted, the temporary filter cover will move upward driven by the support rod. When the movable filter element moves to the vertical assembly, the temporary filter cover will be inserted into the through groove to block the sediment that continues to slide down from the first filter surface and prevent it from flowing directly from the through groove. This ensures that the filtering capacity is always maintained during the cleaning process and impurities in the water are prevented from flowing directly away.

[0047] During the process of resetting the movable filter element, the temporary filter cover support will be reset under the linkage of the support rod.

[0048] As an optional technical solution of the present invention, the height adjustment component includes:

[0049] A first motor, wherein the first motor is fixedly mounted on the surface of the partition, and an output end thereof is fixedly connected with a threaded rod;

[0050] A linkage block, the linkage block is threadedly connected to the surface of the threaded rod and fixedly mounted on the side wall of the annular frame;

[0051] A connecting slide groove is provided on the inner side wall of the fixed shell and the side wall of the partition as a whole, and the linkage block is slidably arranged in the connecting slide groove.

[0052] It should be understood that when the height of the movable filter element needs to be adjusted, the first motor is started, the first motor drives the threaded rod to rotate, the thread of the threaded rod drives the linkage block to move, and the linkage block synchronously drives the annular frame to move, thereby achieving height adjustment of the movable filter element.

[0053] Specifically, a clearance hole is opened at the edge of the temporary filter cover, so as to make way for the threaded rod when the temporary filter cover is inserted into the through groove, thereby avoiding jamming.

[0054] As a technical solution further optimized by the present invention, a diversion baffle is fixedly connected on the inner wall of the sedimentation well and located in the filter cavity to guide the water discharged from the water inlet pipe to the first filter surface.

[0055] Compared with the prior art, the present invention has the following beneficial effects:

[0056] 1. The entire collection process realizes the active cleaning of the filtered sediment away from the bottom of the sedimentation well and raising it to a position close to the opening of the sedimentation well. There is no need to open the well cover during the cleaning process, which is convenient and quick. The active collection process is carried out in the sedimentation well. According to needs, a certain frequency of collection is adopted. On the one hand, it reduces the obstruction of sediment and helps to keep the filter surface of the filter component flowing. On the other hand, it helps to avoid excessive accumulation of sediment, causing agglomeration and increasing the difficulty of cleaning.

[0057] 2. When the sedimentation well needs to be cleaned, you only need to open the well cover and take out the collection pool at the wellhead. There is no need to go deep into the bottom of the sedimentation well for salvage. It is convenient and quick.

[0058] 3. During the filtering process, the flexible filter net of the movable filter element will form an upward convex state, forming a boss-type structure, so that the sediment filtered by the first filter surface slides onto the movable filter element, and after being filtered by the flexible filter net, it can slide along the inclined surface of the boss-type structure of the flexible filter net to the inner edge of the annular frame. During the filtering process of the movable filter element, under the action of gravity, the sediment always accumulates to the inner edge of the annular frame, reducing the obstruction of the flexible filter net, maintaining a certain fluidity, and keeping the sediment in the movable filter element at all times.

[0059] 4. During the conveying process of the vertical conveying assembly, the second motor will drive the conveying rod to rotate, and the conveying rod will drive the turntable to rotate through the driving assembly. The turntable will simultaneously drive the scraper to rotate, and the internal surface of the boss-type structure formed by the downward protrusion will be scraped, which is beneficial to remove the adhesion between the sediment and the flexible filter mesh surface, so that the sediment is gathered to the bottom end of the fixed conveying pipe, which is beneficial to thoroughly clean the sediment in the movable filter element.

[0078] Specifically, a sealing cover 101 is also provided at the top opening of the sedimentation well 1, and the first filter surface 7 and the second filter surface 8 are both made of a rigid filter screen, which may be a stainless steel filter screen;

[0079] It should be understood that during the filtering process, the water discharged from the water inlet pipe 2 will enter the filter chamber 102 and flow to the first filter surface 7 and the second filter surface 8. The first filter surface 7 is fan-shaped and has a certain inclination. The filtered material will slide into the through groove and be collected by the movable filter element and precipitated in the movable filter element, thereby realizing the centralized collection of the filtered sediment. Then, the movable filter element is lifted by the height adjustment component until it is located at the vertical conveying component. In the process of lifting upward, the water in the movable filter element is drained. After reaching the vertical conveying component, the sediment in the movable filter element is vertically conveyed to the collection tank 5 by the vertical conveying component.

[0080] During the entire collection process, the filtered sediment is actively cleaned away from the bottom of the sedimentation well 1 and raised to a position close to the opening of the sedimentation well 1. During the cleaning process, there is no need to open the cover of the sedimentation well 1, which is convenient and quick. The active collection process is carried out in the sedimentation well 1. According to needs, a certain frequency of collection is adopted. On the one hand, it reduces the obstruction of the sediment, which is beneficial to keep the filter surface of the filter component unobstructed. On the other hand, it is beneficial to avoid excessive accumulation of sediment, causing agglomeration, and increasing the difficulty of cleaning.

[0081] It should be noted that when the sedimentation well 1 needs to be cleaned, it is only necessary to open the well cover and take out the collection pool at the wellhead, without going deep into the bottom of the sedimentation well 1 for salvage, which is convenient and quick.

[0085] An elastic support member, both ends of which are fixedly connected to the moving plate 10 and the bottom of the sedimentation well 1 respectively, so as to support the moving plate 10 .

[0086] It should be understood that during the filtering process, the flexible filter mesh 11 of the movable filter element will form an upward convex state, forming a boss-type structure, so that the sediment filtered by the first filter surface 7 slides onto the movable filter element, and after being filtered by the flexible filter mesh 11, it can slide along the inclined surface of the boss-type structure of the flexible filter mesh 11 to the inner edge of the annular frame 9. During the filtering process of the movable filter element, under the action of gravity, the sediment always accumulates on the inner edge of the annular frame 9, reducing the obstruction of the flexible filter mesh 11, maintaining a certain fluidity, and keeping the sediment in the movable filter element at all times.

[0087] It should be further explained that if the flexible filter screen 11 is quickly clogged, the water will be stirred in the annular frame 9 and the sediment will be taken out. Therefore, it is necessary to maintain the circulation and drain the water collected in the annular frame 9 in time.

[0092] It should be understood that, under the support of the elastic support member, the support rod 13 always maintains support for the movable plate 10, and the movable plate 10 props up the flexible filter net 11 to form a boss-type structure. Under the support of the elastic support member, when it is hit by sediment or water, it will also generate vibration, which is conducive to shaking and cleaning the sediment on the surface of the flexible filter net 11.

The flexible filter screen 11 will form a boss-type structure downward, and the sediment on the inner edge of the annular frame 9 will begin to gather to the top of the movable plate 10 until the bottom end of the fixed delivery pipe 15 is tightly pressed against the top surface of the movable plate 10, which is conducive to concentrating the collected sediment to the bottom end of the fixed delivery pipe 15, preparing for vertical delivery, and facilitating thorough cleaning of the sediment collected in the movable filter element.

[0101] It should be further explained that the movable conveying pipe 16 is rotatable. When the collecting tank 5 needs to be removed, the discharge pipe 1601 can be moved away from the collecting tank 5 by rotating the movable conveying pipe 16, so that the staff can disassemble and assemble the collecting tank 5 conveniently.

The turntable 22 will simultaneously drive the scraper 24 to rotate, and the internal surface of the boss-type structure formed by the downward protrusion is scraped, which is beneficial to remove the adhesion between the sediment and the surface of the flexible filter net 11, so that the sediment gathers to the bottom end of the fixed conveying pipe 15, which is beneficial to thoroughly clean the sediment in the movable filter element.

[0106] As a further optimized embodiment of the present invention, the top of the connecting seat 23 has a limiting end 25 for limiting the upward flipping angle of the scraper 24.

[0107] It should be understood that by setting the limit end 25, the flipping angle of the scraper 24 is limited. When the flexible filter screen 11 is pulled downward and tightened, the scraper 24 will be driven to flip upward. When a downward boss-type structure is formed, the scraper 24 is attached to the surface of the flexible filter screen 11 under the restriction of the limit end 25, preparing for the subsequent scraping and cleaning.

[0114] Specifically, the temporary filter cover 28 is made of a rigid filter mesh, which may be a stainless steel filter mesh.

[0115] It should be understood that when the movable filter element is lifted, the temporary filter cover 28 will move upward driven by the support rod 13. When the movable filter element moves to the vertical assembly, the temporary filter cover 28 will be inserted into the through groove to block the sediment that continues to slide down from the first filter surface 7 and prevent it from flowing directly from the through groove. This ensures that the filtering capacity is always maintained during the cleaning process and impurities in the water are prevented from flowing directly away.
