Description

Technical Field

[0001] This utility model relates to the field of pipeline anti-siltation technology, specifically to a water conservancy pipeline anti-siltation device. Background Technology

[0002] Water conservancy pipelines are pipeline systems consisting of pipes, valves and ancillary facilities, mainly used for the transportation and distribution of media such as water and sewage.

[0003] Wastewater contains many impurities such as silt and sand, which need to be filtered and separated before entering the pipeline; otherwise, it can easily cause blockage of the pipe network. Currently, filter plates can be used to intercept silt and sand and other impurities, ensuring that they do not flow into subsequent pipes. However, filter plates are prone to clogging during use, requiring frequent cleaning by staff. Based on this, a silt-prevention device for water conservancy pipe networks is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a water conservancy pipeline anti-clogging device. It separates impurities and water through a rotatable filter cylinder, preventing impurities such as silt from entering subsequent pipelines. It can also periodically discharge impurities such as silt from the pipe shell to avoid clogging.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water conservancy pipeline anti-siltation device, comprising a pipe shell, with an inlet pipe and a drain pipe sequentially connected to the top and side ends of the pipe shell, sleeves symmetrically rotated at the ends of the pipe shell, and the same filter cylinder connected between the inner ends of the two sleeves, wherein the end of one sleeve away from the filter cylinder is closed, and a servo motor for driving the rotation of the sleeve is installed at the outer end of the pipe shell, and the outer end of the other sleeve is connected to the drain pipe; The inner wall of the tube is symmetrically fixed with frames on both sides of the filter cartridge. Several blades are installed at the top of the frame to cut the entangled material on the surface of the filter cartridge, and a brush for cleaning the mud and sand on the surface of the filter cartridge is installed at the bottom of the frame.

[0006] Preferably, the filter cartridge has multiple flow holes extending through its inner and outer sides. The flow holes are truncated cone-shaped, with the inner dimension being larger than the outer dimension, and rotate with the filter cartridge to smoothly eject mud and sand.

[0007] Preferably, the filter cartridge is provided with a water spray pipe, the end of which extends away from the drain pipe to the outside of the sleeve, and is equipped with a sealing valve.

[0008] Preferably, the output shaft of the servo motor is equipped with a main gear, and a secondary gear meshes with the outer end of the main gear, with the secondary gear sleeved on the outer end of the corresponding sleeve.

[0009] Preferably, valve one is installed on the inlet pipe and valve two is installed on the outlet pipe.

[0010] Preferably, the bottom end of the tube shell is connected to a material hopper with a sealing cap.

[0011] Preferably, the two sleeves pass through the frame but do not contact the frame.

[0012] This utility model provides a device for preventing siltation in water conservancy pipelines, which has the following advantages compared with the prior art: 1. The system is equipped with a casing, a rotatable filter cartridge, and a collection hopper. Initially, wastewater enters the casing through the pipe, and the liquid flows into the filter cartridge. Impurities such as silt are blocked on the surface of the filter cartridge. During this process, the rapid rotation of the filter cartridge quickly throws out the very small amount of silt that has entered the cartridge, preventing silt from accumulating and ensuring the long-term normal use of the filter cartridge. When it is necessary to discharge silt and other impurities from the casing, valves one and two are closed to cut off the water flow. Then, the sealing cap is unscrewed, and the silt and other impurities deposited at the bottom of the collection hopper, along with the wastewater remaining in the casing, are discharged from the bottom of the collection hopper. This allows for the periodic discharge of silt and other impurities from the casing, preventing blockage.

[0013] 2. The system includes a frame, blades, and brushes. The bottom of the blades is close to the surface of the filter cartridge, and the brush bristles are just touching the filter cartridge. As the filter cartridge rotates rapidly, the brushes remove impurities such as mud and sand that can be deposited on the surface of the filter cartridge. For some tangled materials, it is inconvenient for the brushes to clean them. In this case, the blades can cut off these tangled materials first, making it easier for the brushes to clean the small pieces of tangled materials off the surface of the filter cartridge later. Through the cooperation of the brushes and blades, the mud and sand and other impurities on the surface of the filter cartridge can be cleaned off more effectively, ensuring the normal operation of the filter cartridge.

[0016] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0017] Wastewater contains a lot of silt and impurities, which need to be filtered and separated before entering the pipeline; otherwise, it can easily cause blockage of the pipe network. Filter plates can be used to intercept silt and other impurities, preventing them from flowing into subsequent pipes, but filter plates are prone to clogging. Therefore, this embodiment provides a water conservancy pipe network anti-clogging device, such as... Figures 1-4 As shown, it includes a casing 1, with a hopper 14 equipped with a sealing cap connected to the bottom end of the casing 1. Under the action of gravity, the intercepted mud and other impurities slowly settle in the lower part of the hopper 14. The top and side ends of the casing 1 are connected to an inlet pipe 2 and an outlet pipe 3 in sequence. A valve 21 is installed on the inlet pipe 2, and a valve 31 is installed on the outlet pipe 3. Opening valves 21 and 31 ensures the normal flow of water in the pipes. Closing valves 21 and 31 cuts off the water flow, allowing the mud and other impurities in the casing 1 to be cleaned. A sleeve 5 is symmetrically and rotatably installed at the end of the tube shell 1. The inner ends of the two sleeves 5 are connected and the same filter cartridge 4 is installed. The end of one sleeve 5 away from the filter cartridge 4 is closed, and a servo motor 13 is installed at the outer end of the tube shell 1 to drive the sleeve 5 to rotate. The outer end of the other sleeve 5 is connected to the drain pipe 3. By starting the servo motor 13, the sleeve 5 is driven to rotate, which in turn drives the filter cartridge 4 to rotate.

[0018] During operation, initial wastewater enters the casing 1 through the pipe, and the liquid flows into the filter cartridge 4. Impurities such as silt are trapped on the surface of the filter cartridge 4, resulting in a very low sand content. The liquid enters the filter cartridge 4 through the left sleeve 5 into the drain pipe 3, and finally flows smoothly into the pipeline of the next section. The filter cartridge 4 traps impurities such as silt within the casing 1. During this process, the servo motor 13 drives the right sleeve 5 to rotate, thereby driving the filter cartridge 4 to rotate rapidly. Centrifugal force quickly ejects the very small amount of silt that has entered the filter cartridge 4, preventing silt from gradually accumulating inside and ensuring the filter cartridge 4's long-term normal operation. When it is necessary to drain silt and other impurities from the casing 1, valves 21 and 31 are closed to cut off the water flow. Then, the sealing cap is unscrewed, and the silt and other impurities deposited at the bottom of the hopper 14, along with the wastewater remaining in the casing 1, are discharged from the bottom of the hopper 14. Regularly draining silt and other impurities from the casing 1 can prevent clogging.

[0019] The entanglement of mud, sand, hair, and other debris in the wastewater adheres and accumulates on the surface of the filter cartridge 4, easily causing blockage of the flow holes 41 on the filter cartridge 4, severely reducing the separation rate of wastewater inside the shell 1. The following solution is provided to address the above problem: A frame 6 is symmetrically fixed on both sides of the inner wall of the tube shell 1. Several blades 7 are installed at the top of the frame 6 to cut off the entangled material on the surface of the filter cartridge 4. The blades 7 are made of stainless steel. A brush 8 for cleaning the mud and sand on the surface of the filter cartridge 4 is installed at the bottom of the frame 6. The brush 8 is made of corrosion-resistant plastic.

[0020] During use, the bottom end of the blade 7 is close to the surface of the filter cartridge 4, and the bristles of the brush 8 are just in contact with the filter cartridge 4. With the rapid rotation of the filter cartridge 4, the brush 8 removes impurities such as mud and sand that can be deposited on the surface of the filter cartridge 4. For some tangled materials, it is inconvenient for the brush 8 to clean them. At this time, the blade 7 can cut off these tangled materials first, so that the brush 8 can clean the small pieces of tangled materials off the surface of the filter cartridge 4 later. Through the cooperation of the brush 8 and the blade 7, the impurities such as mud and sand on the surface of the filter cartridge 4 can be cleaned off more effectively, ensuring the normal operation of the filter cartridge 4.

[0021] In order to discharge the small amount of mud and sand in the filter cylinder 4 more efficiently, multiple flow holes 41 are opened through the inside and outside of the filter cylinder 4. The flow holes 41 are frustum-shaped, with the inner dimension being larger than the outer dimension, and they rotate with the filter cylinder 4 to smoothly throw out the mud and sand.

[0022] After prolonged filtration, the inner surface of the filter cartridge 4 inevitably retains some mud and sand. A water spray pipe 9 is installed inside the filter cartridge 4. The end of the water spray pipe 9 that is away from the drain pipe 3 extends to the outside of the sleeve 5 and is equipped with a sealing valve 10.

[0023] When in use, after draining the mud and sand and other impurities from the bottom of the hopper 14, open the sealing valve 10 and connect the external water injection pipe. Inject high-pressure water into the spray pipe 9 through the water injection pipe. The high-pressure water sprays out quickly, which can wash the inner surface of the filter cartridge 4. By washing from the inside out, some of the mud and sand on the inner surface of the filter cartridge 4 can be flushed out through the flow hole 41 in a thorough and efficient manner.

[0024] In this embodiment, a main gear 11 is mounted on the output shaft of the servo motor 13, and a secondary gear 12 meshes with the outer end of the main gear 11. The secondary gear 12 is sleeved on the outer end of the corresponding sleeve 5. When the servo motor 13 is started, the main gear 11 is driven to rotate, which in turn drives the secondary gear 12 to rotate, thereby driving the right sleeve 5 to rotate, causing the filter cartridge 4 to rotate rapidly.

[0025] In this embodiment, the two sleeves 5 pass through the frame 6 but do not contact the frame 6.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
