Description

Technical Field

[0001] This invention relates to the field of drainage technology, and in particular to a swamp drainage device with anti-clogging function. Background Technology

[0002] As a special type of wetland environment, marshland contains a large number of impurities in its water, including aquatic plants, roots and stems, fibrous materials, mud and sand, humus clumps, etc. The impurities are complex in type and high in content, and are easy to entangle and accumulate, which brings great difficulties to the pumping operation.

[0003] Currently, most existing swamp drainage devices use ordinary sewage pumps combined with filter screens. While these can achieve basic pumping functions, they have several drawbacks in actual use: First, ordinary filter screens are mostly flat or cylindrical fixed structures, which are easily clogged by impurities, especially fibrous impurities and fine silt. These easily adhere to the filter screen surface, leading to a decrease in water intake, increased energy consumption, and even jamming and shutdown. Frequent manual cleaning is required, resulting in high maintenance costs and low efficiency. Second, the existing devices' crushing structures are mostly single-stage cutting, which is insufficient to thoroughly crush large pieces and fibrous impurities in the swamp. Uncrushed impurities easily clog the inlet pipe and filter screen, making long-term stable self-cleaning impossible.

[0004] In view of the shortcomings of the existing technology, there is an urgent need for a swamp drainage device with anti-clogging function that can achieve multi-level anti-clogging and self-cleaning. Summary of the Invention

[0005] To overcome the drawback of being easily clogged by impurities, the technical problem to be solved is to provide a swamp drainage device with multi-stage anti-clogging and self-cleaning functions.

[0006] The technical solution is as follows: A swamp drainage device with anti-clogging function includes a water pump, wherein the water pump is provided with an impeller and a water outlet is provided on the water pump; The water inlet pipe is connected to the water inlet end of the water pump. A guide groove is provided on the inner wall of the water inlet pipe. A rotating shaft passes through the water inlet pipe and is coaxially connected to the impeller. A preliminary crushing assembly, the preliminary crushing assembly including a rotating blade disposed at the end of the rotating shaft, the rotating blade being located at the water inlet of the water inlet pipe; A filter assembly, comprising a filter screen disposed inside an inlet pipe, the filter screen being sleeved on the outer wall of the rotating shaft; The ultimate pulverizing assembly includes a rotating ring disposed inside a water inlet pipe, with blades arranged around the circumference of the rotating ring, the blades contacting the inner wall of the water inlet pipe.

[0007] Furthermore, the guide groove is a spiral groove, and the water flow in the inlet pipe forms a spiral water flow through the guide groove, causing impurities to be thrown towards the inner wall of the inlet pipe.

[0008] Furthermore, the filter screen has a conical structure, and the spiral water flow causes water to converge and be filtered by the filter screen. Impurities slide upward along the conical filter screen, and the water flows into the water pump after being filtered by the filter screen.

[0009] Furthermore, the blade is inclined, and the spiral direction of the guide groove is consistent with the inclination direction of the blade, so that the spiral water flow can drive the rotating ring and the blade to rotate.

[0010] Furthermore, it also includes a vibrating plate. The inner wall of the filter screen is provided with a vibrating plate, and the outer wall of the rotating shaft is provided with nylon cloth. Vibrating balls are provided on the nylon cloth. When the rotating shaft moves, the vibrating balls strike the vibrating plate under the action of centrifugal force.

[0011] Furthermore, it also includes a scraping plate, which is connected to the bottom of the rotating ring and is attached to the outer wall of the filter screen.

[0012] Furthermore, it also includes a collection ring, which is provided inside the water inlet pipe. The collection ring has filter holes, and a support frame is connected to the bottom of the collection ring. The filter screen is connected to the support frame.

[0013] Furthermore, it also includes a rectangular frame, which is connected to the filter screen. A cutting blade slides in a sealed manner inside the rectangular frame, and a fixed shaft slides inside the rectangular frame. A sealing gasket is provided between the rectangular frame and the fixed shaft, and an elastic element is provided between the rectangular frame and the cutting blade. The elastic element is sleeved on the fixed shaft.

[0014] Furthermore, it also includes a trigger post, which is provided on the outside of the rotating shaft, and an arc-shaped frame is provided on the fixed shaft, the arc-shaped frame cooperating with the trigger post.

[0015] Furthermore, it also includes an arc-shaped door, a cleaning port is provided on the water inlet pipe, an arc-shaped door is rotatably connected to the water inlet pipe, the arc-shaped door cooperates with the cleaning port, an arc-shaped pad is provided on the arc-shaped door, the arc-shaped pad fits against the outer wall of the water inlet pipe, and a bolt is threaded onto the arc-shaped door.

[0016] The beneficial effects of this invention are: 1. This invention uses a rotating blade at the water inlet to initially crush large impurities in the swamp, thereby reducing the risk of clogging. Then, the spiral guide groove on the inner wall of the water inlet pipe guides the water flow to form a spiral water flow. Using centrifugal force, the impurities are thrown against the wall of the water inlet pipe, causing the water flow to converge and filter through the filter screen, achieving the initial separation of impurities from water. The impurities then slide along the outer wall of the conical filter screen, avoiding the effect of impurities accumulating and clogging the filter screen.

[0017] 2. This invention utilizes the cooperation between the vibrating plate on the inner wall of the filter screen and the vibrating ball driven by the rotating shaft. During the rotation of the shaft, the vibrating ball impacts the vibrating plate with the help of centrifugal force, causing the filter screen to vibrate and shake off small impurities inside the mesh, thus achieving self-cleaning of the filter screen mesh. At the same time, the rotating ring will drive the scraping plate to rotate synchronously when it rotates. The scraping plate is in close contact with the outer wall of the filter screen, which can effectively scrape off the residual impurities attached to the surface of the filter screen, thereby improving the continuous operating efficiency of the device.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0021] A swamp drainage device with anti-clogging function, such as Figures 1-9As shown, the system includes a water pump 1, which contains an impeller 10. When the motor starts, it drives the impeller 10 to rotate at high speed, generating suction to pump water. The water pump 1 has an outlet 11 for discharging filtered water. A drain pipe can be connected to the outlet 11 to facilitate water transport over distances, depending on actual pumping requirements. The inlet pipe 2 is a cylindrical hollow structure, with one end sealed to the inlet end of the water pump 1 using a rubber seal. The system is sealed to prevent leakage. The other end of the water inlet pipe 2 is a water inlet. The water inlet of the water inlet pipe 2 is moved to the water accumulation area of ​​the swamp to extract water and impurities from the swamp. The inner wall of the water inlet pipe 2 is provided with a guide groove 20, which is a spiral groove. The water in the water inlet pipe 2 flows through the guide groove 20 to form a spiral water flow, which throws impurities toward the inner wall of the water inlet pipe 2, achieving the initial separation of impurities and water. A rotating shaft 21 is inserted inside the water inlet pipe 2, and the rotating shaft 21 is coaxially and fixedly connected to the impeller 10. The preliminary crushing component includes a rotating blade 3 fixedly installed at the end of the rotating shaft 21. The rotating blade 3 is located at the inlet of the water inlet pipe 2. When the rotating shaft 21 rotates with the impeller 10, the rotating blade 3 rotates synchronously at high speed to cut and crush large impurities entering the water inlet pipe 2 into smaller impurity particles, preventing large impurities from clogging the inlet of the water inlet pipe 2. The filter assembly includes a filter screen 4 disposed inside the water inlet pipe 2. One end of the filter screen 4 is rotatably sleeved on the outer wall of the rotating shaft 21, and the other end of the filter screen 4 is left with a gap between it and the inside of the water inlet pipe 2. The filter screen 4 has a conical structure. The spiral water flow causes the water to converge and filter towards the filter screen 4. Impurities slide upward along the conical filter screen 4. After the water is filtered by the filter screen 4, it enters the water pump 1. The ultimate pulverizing assembly includes a rotating ring 5 rotatably disposed inside the water inlet pipe 2. Multiple blades 50 are fixedly installed on the circumference of the rotating ring 5. The blades 50 are inclined. The spiral direction of the guide groove 20 is consistent with the inclination direction of the blades 50, so that the spiral water flow can drive the rotating ring 5 and the blades 50 to rotate. The blades 50 contact the inner wall of the water inlet pipe 2.

[0022] like Figure 4 and Figure 6 As shown, it also includes a vibrating plate 40. The vibrating plate 40 is fixedly installed on the inner wall of the filter screen 4. A nylon cloth 41 is connected to the outer wall of the rotating shaft 21. A vibrating ball 42 is connected to the nylon cloth 41. When the rotating shaft 21 rotates, the vibrating ball 42 is thrown outward under the action of centrifugal force and periodically hits the vibrating plate 40, causing the filter screen 4 to vibrate and shake off the fine impurities attached to the mesh of the filter screen 4, thereby achieving the cleaning effect of the mesh of the filter screen 4.

[0023] like Figure 3 and Figure 5As shown, it also includes a scraping plate 7. The scraping plate 7 is fixedly installed at the bottom of the rotating ring 5. The scraping plate 7 is attached to the outer wall of the filter screen 4. When the rotating ring 5 rotates, the scraping plate 7 rotates synchronously to scrape off the residual impurities attached to the outer wall of the filter screen 4.

[0024] like Figures 3-4 and Figure 9 As shown, it also includes a collection ring 6. A collection ring 6 is fixedly installed inside the water inlet pipe 2. The collection ring 6 is located above the filter screen 4. Multiple filter holes 60 are opened on the collection ring 6. A support frame 61 is fixedly connected to the bottom of the collection ring 6. The filter screen 4 is connected to the support frame 61.

[0025] like Figures 7-8 As shown, it also includes a rectangular frame 8, which is fixedly connected to the filter screen 4. A cutting blade 80 slides in a sealed manner inside the rectangular frame 8, and a fixed shaft 81 slides inside the rectangular frame 8. A sealing gasket 84 made of rubber is provided between the rectangular frame 8 and the fixed shaft 81 to prevent water from entering the interior of the rectangular frame 8. An elastic element 83 is provided between the rectangular frame 8 and the cutting blade 80. The elastic element 83 is sleeved on the fixed shaft 81, with one end fixedly connected to the interior of the rectangular frame 8 and the other end fixedly connected to the cutting blade 80 for resetting the cutting blade 80. A trigger post is fixedly provided on the outside of the rotating shaft 21. 85. An arc-shaped frame 82 is provided on the fixed shaft 81. The arc-shaped frame 82 cooperates with the trigger post 85. When the rotating shaft 21 rotates, the trigger post 85 will periodically squeeze the arc-shaped frame 82, pushing the arc-shaped frame 82 and the fixed shaft 81 to slide away from the rotating shaft 21, thereby driving the cutting blade 80 to slide synchronously and cut the entangled fibrous impurities. When the trigger post 85 separates from the arc-shaped frame 82, the elastic element 83 resets, driving the cutting blade 80 to slide closer to the rotating shaft 21, realizing the reciprocating cutting of the cutting blade 80, realizing the cutting of fibrous impurities, and avoiding blockage caused by fiber entanglement.

[0026] like Figure 9 As shown, it also includes an arc-shaped door 9. The water inlet pipe 2 has a cleaning port corresponding to the collection ring 6. The arc-shaped door 9 is rotatably connected to the water inlet pipe 2 via a hinge. The arc-shaped door 9 cooperates with the cleaning port. An arc-shaped pad 90 is provided on the arc-shaped door 9. The arc-shaped pad 90 is made of rubber. When the arc-shaped door 9 is closed, the arc-shaped pad 90 fits tightly against the outer wall of the water inlet pipe 2 to seal the cleaning port and prevent water from leaking from the cleaning port. A bolt 91 is threadedly connected to the arc-shaped door 9. The thread of the bolt 91 passes through the arc-shaped door 9 and is threadedly connected to the water inlet pipe 2. When it is necessary to clean the impurities in the collection ring 6, the bolt 91 is turned to open the arc-shaped door 9, and the impurities in the collection ring 6 can be cleaned.

[0027] When this device is in operation, the water pump 1 is started, which drives the impeller 10 to rotate at high speed. The rotation of the impeller 10 generates suction force, and water and impurities in the swamp enter the inlet pipe 2 through the inlet of the inlet pipe 2. At the same time, the impeller 10 drives the rotating shaft 21 to rotate synchronously at high speed, and the rotating shaft 21 drives the rotating blade 3 to rotate at high speed, which initially crushes the large pieces of impurities entering the inlet pipe 2, preventing the impurities in the swamp from clogging the inlet of the inlet pipe 2.

[0028] After initial crushing, the impurities flow synchronously with the water flow in the inlet pipe 2. During the flow, the water flow forms a spiral flow under the action of the guide groove 20. The spiral flow generates centrifugal force, and the crushed impurities in the spiral flow are thrown towards the inner wall of the inlet pipe 2. The impurities continue to move along the inner wall of the inlet pipe 2. At the same time, the spiral flow enters the filter screen 4, and the filter screen 4 further filters the impurities again. The filtered impurities move along the filter screen 4, achieving the effect of impurity separation. The filtered water flows into the water pump 1 and is finally discharged through the outlet 11.

[0029] As the spiral water flow moves within the inlet pipe 2, it simultaneously impacts the inclined blades 50. The blades 50 drive the rotating ring 5 to rotate, and the blades 50 perform ultimate crushing of impurities adhering to the inner wall of the inlet pipe 2. The crushed impurities are then forced into the collection ring 6 by the inclined blades 50, which also cleans the inner wall of the inlet pipe 2. When the rotating ring 5 rotates, it drives the scraper 7 to rotate synchronously. The scraper 7 cleans the residual impurities adhering to the outer wall of the filter screen 4, preventing the filter screen 4 from becoming clogged. At the same time, when the rotating shaft 21 rotates, it drives the nylon cloth 41 to rotate, which in turn drives the vibrating ball 42 to rotate. Under the action of centrifugation, the vibrating ball 42 tauts the nylon cloth 41. When the vibrating ball 42 swings, it hits the vibrating plate 40, causing the vibrating plate 40 to vibrate, which in turn drives the filter screen 4 to vibrate. After the filter screen 4 vibrates, the fine impurities inside the mesh of the filter screen 4 fall off, achieving a dual cleaning function for the filter screen 4.

[0030] The scraped-off impurities move along the inner wall of the inlet pipe 2 with the spiral water flow and finally enter the collection ring 6. At the same time, the water in the collection ring 6 flows back to the inlet pipe 2 through the filter hole 60. The impurities accumulate in the collection ring 6. When the impurities in the collection ring 6 accumulate to a certain amount, the bolt 91 is turned to disengage from the inlet pipe 2, and the arc-shaped door 9 is opened to clean the impurities in the collection ring 6.

[0031] During the operation of the device, the rotating shaft 21 synchronously drives the trigger column 85 to rotate. When the trigger column 85 rotates, it periodically squeezes the arc frame 82. The arc frame 82 drives the fixed shaft 81 to slide along the sealing gasket 84. The fixed shaft 81 drives the cutting blade 80 to slide along the rectangular frame 8, cutting the fibrous impurities wrapped on the rotating shaft 21, avoiding blockage caused by fiber entanglement, and ensuring the long-term stable operation of the device.
