Description

Technical Field

[0001] This utility model relates to the field of dredging device technology, specifically a high-pressure flushing and suction integrated dredging device suitable for narrow spaces. Background Technology

[0002] Flushing and dredging devices are equipment that use high-pressure water flow and other technologies to clean silt and debris from pipes, pools and other facilities. There are various types of such devices.

[0003] For example, the authorization announcement number "CN204266366U" is titled "Automatic Vacuum Flushing and Sludge Removal Device for Water Tanks". When the vacuum diaphragm valve is opened, the flushing water in the flushing chamber enters the water tank and carries away the sludge in the water tank. It has the advantages of simple structure and water conservation. Existing vacuum flushing and sludge removal devices are used for flushing and sludge removal in water tanks with relatively large open areas. However, there are many narrow and long water storage wells in cities or rural areas. If the well channels are not cleaned for a long time, a thick layer of sludge will accumulate. Currently, the equipment for large-area cleaning and sludge removal cannot enter the narrow space to contact the sludge, and therefore cannot achieve a good sludge removal effect.

[0004] Meanwhile, the most common method for cleaning sludge using existing vacuum flushing and dredging devices is to discharge the cleaned sludge through a sludge discharge pipe. However, the sludge contains a lot of dead leaves and twigs, and a lot of humus can also form complex and tight blockages. When the pipe diameter is relatively small, sludge impurities can easily accumulate at pipe bends, clogging the pipe or affecting the smooth discharge of sludge, thus reducing the cleaning efficiency of the vacuum flushing and dredging device. Utility Model Content

[0005] The purpose of this invention is to solve the problems of existing vacuum flushing and sludge removal devices, which cannot enter narrow spaces to contact sludge when cleaning large areas, thus failing to achieve good sludge removal results, and the easy accumulation of mud and impurities at pipe bends, which can block pipes or affect the smooth discharge of mud and reduce the cleaning efficiency of vacuum flushing and sludge removal devices. Therefore, this invention proposes a high-pressure flushing and sludge suction integrated sludge removal device suitable for narrow spaces.

[0006] To achieve the above objectives, this utility model provides the following technical solution: Design a high-pressure flushing and sludge suction integrated sludge removal device suitable for narrow spaces, including a sludge removal well, a sludge layer and a water inlet pipe. The sludge layer is fixedly installed at the lower end of the sludge removal well. The lower end of the water inlet pipe is fixedly connected to a high-pressure cleaning structure. A sludge suction and anti-clogging structure is provided above the sludge layer.

[0007] Preferably, the high-pressure cleaning structure includes a connecting flange and a water supply pipe. The connecting flange is threadedly connected to the lower end of the water inlet pipe by bolts. A connecting pipe is threadedly connected to the other side of the connecting flange. A high-pressure water pump is fixedly installed on one side of the connecting pipe. One end of the high-pressure water pump is fixedly connected to the water supply pipe. A water outlet is fixedly installed at the other end of the water supply pipe. A high-pressure nozzle is fixedly installed on the outside of the water outlet.

[0008] Preferably, the water supply pipe has an integrated pipe structure on its outer side, the integrated pipe structure including a support sleeve and a parallel sleeve, the parallel sleeve being fixedly fitted onto the outer wall of the water supply pipe, a connecting rod being fixedly installed on one side of the parallel sleeve, a support sleeve being fixedly installed on the other end of the connecting rod, a connecting ring being fixedly fitted onto the upper outer wall of the water supply pipe, and an overlap plate being fixedly installed on the outer wall of the connecting ring.

[0009] Preferably, the sludge suction and anti-clogging structure includes a suction hood and a discharge pipe. The suction hood is movably disposed above the sludge layer. The top of the suction hood is fixedly connected to the discharge pipe. A sludge suction pump is fixedly installed at the top of the discharge pipe. A crossbeam is fixedly installed on the inner wall of the suction hood. A waterproof motor is fixedly installed on the inner side of the crossbeam. A pulverizing wheel is fixedly installed at the lower end of the output shaft of the waterproof motor.

[0010] Preferably, the pulverizing wheel is rotatably connected to the lower inner wall of the suction hood, the outer side of the drain pipe is fixedly sleeved with the inner side of the support sleeve, and the side wall of the drain pipe is fixedly connected to the other end of the overlapping plate.

[0011] Preferably, the lower end of the connecting pipe is provided with a water filling and drainage structure, the water filling and drainage structure includes a control valve and a vertical pipe, the control valve is fixedly connected to the lower end of the connecting pipe, the lower end of the control valve is fixedly connected to the vertical pipe, and the lower end of the vertical pipe is connected to a water outlet pipe through a connecting flange thread.

[0012] Preferably, the side wall of the vertical pipe is connected to the other end of the sewage pipe.

[0013] This utility model proposes a high-pressure flushing and sludge suction integrated cleaning device suitable for narrow spaces. The advantages are as follows: the parallel sleeve is made of aluminum alloy and is clamped on the outside of the water supply pipe, while the support sleeve is clamped on the outside of the drain pipe on the other side. The parallel sleeve and the support sleeve are welded together by a transverse connecting rod. The water supply pipe and the drain pipe are arranged side by side and close to each other. The whole device is relatively slender and can be inserted into deep or narrow wells. The upper connecting ring and the overlapping plate connect the upper part of the outside of the water supply pipe and the outside of the drain pipe together. This makes it more suitable for flushing and sludge cleaning work in narrow outdoor wells.

[0014] The suction hood is made of semi-circular plastic material. It can bring the bottom of the sewage pipe close to the sludge after high-pressure washing. After the suction pump at the top is connected to the power source and started, it can generate suction to draw the sludge upward into the sewage pipe. After the waterproof motor is connected to the power source and started, the metal crushing wheel below rotates at high speed inside the lower part of the suction hood. The rotating crushing wheel will crush the weeds and dead branches mixed in the sludge, making it less likely for debris to clog the sewage pipe, protecting the sewage pipe and improving the sludge removal efficiency.

[0017] The present invention will be further described below with reference to the accompanying drawings: Example: Please refer to Figure 1-6 In this embodiment, a high-pressure flushing and sludge suction integrated sludge removal device suitable for narrow spaces includes a sludge removal well 1, a sludge layer 2, and a water inlet pipe 3. The sludge layer 2 is fixedly installed at the lower end of the sludge removal well 1. The sludge layer 2 is the sludge and debris accumulated at the bottom of the narrow sludge removal well 1. The lower end of the water inlet pipe 3 is fixedly connected to a high-pressure cleaning structure 4. The water inlet pipe 3 is used to connect to an external water source for high-pressure cleaning. A sludge suction and anti-clogging structure 5 is provided above the sludge layer 2.

[0018] The high-pressure cleaning structure 4 includes a connecting flange 41 and a water supply pipe 44. The connecting flange 41 is connected to the lower end of the water inlet pipe 3 by bolts and threads. The connecting flange 41 connects the top end of the stainless steel connecting pipe 42 to the lower end of the water inlet pipe 3. The connecting pipe 42 is threaded to the other side of the connecting flange 41. A high-pressure water pump 43 is fixedly installed on one side of the connecting pipe 42. When the high-pressure water pump 43 is powered on, it will inject external water into the water supply pipe 44. One end of the high-pressure water pump 43 is fixedly connected to the water supply pipe 44. The other end of the water supply pipe 44 is fixedly installed with a water outlet 45. The water outlet 45 will guide the water flow in the water supply pipe 44 to the high-pressure nozzle 46 for spraying. The high-pressure nozzle 46 is vertically downward to clear away the accumulated layer of silt and mix it into a more treatable slurry. The high-pressure nozzle 46 is fixedly installed on the outside of the water outlet 45.

[0019] An integrated pipe structure 6 is provided on the outside of the water supply pipe 44. The integrated pipe structure 6 includes a support sleeve 61 and a parallel sleeve 63. The parallel sleeve 63 is fixedly fitted onto the outer wall of the water supply pipe 44. The parallel sleeve 63 is made of aluminum alloy and is clamped onto the outside of the water supply pipe 44. The support sleeve 61 is clamped onto the outside of the sewage pipe 55 on the other side. The parallel sleeve 63 and the support sleeve 61 are welded together by a transverse connecting rod 62. The water supply pipe 41 and the sewage pipe 55 are set side by side and close to each other. The overall structure is relatively slender and can be used in deep or narrow wells. A connecting rod 62 is fixedly installed on one side of the parallel sleeve 63. The upper connecting ring 65 and the overlapping plate 64 connect the upper part of the outer side of the water supply pipe 44 and the outer side of the sewage pipe 55 together. The support sleeve 61 is fixedly installed on the other end of the connecting rod 62. A connecting ring 65 is fixedly fitted onto the upper outer wall of the water supply pipe 44. An overlapping plate 64 is fixedly installed on the outer wall of the connecting ring 65.

[0020] The sludge suction and anti-clogging structure 5 includes a suction hood 51 and a discharge pipe 55. The suction hood 51 is movably positioned above the sludge layer 2. The suction hood 51 is made of a semi-circular plastic material. The suction hood 51 allows the lowest end of the discharge pipe 55 to approach the sludge after high-pressure washing. After the suction pump 56 at the top is connected to the power supply and started, it can generate suction to draw the sludge upward into the discharge pipe 55. The top of the suction hood 51 is fixedly connected to the discharge pipe 55, and the suction pump 56 is fixedly installed at the top of the discharge pipe 55. A crossbeam 52 is fixedly installed on the inner wall of the suction hood 51, and a crossbeam 52 is fixedly installed on the inner side of the crossbeam 52. The waterproof motor 53 is a servo motor. After the waterproof motor 53 is connected to the power supply and started, it can make the metal crushing wheel 54 below rotate at high speed inside the lower end of the suction hood 51. The rotating crushing wheel 54 will crush the weeds and dead branches mixed in the mud, and the sewage pipe 55 will not easily become clogged. The crushing wheel 54 is fixedly installed at the lower end of the output shaft of the waterproof motor 53. The crushing wheel 54 is rotatably connected to the lower inner wall of the suction hood 51. The outer side of the sewage pipe 55 is fixedly sleeved with the inner side of the support sleeve 61, and the side wall of the sewage pipe 55 is fixedly connected to the other end of the overlapping plate 64.

[0021] The lower end of the connecting pipe 42 is equipped with a water filling and sewage discharge structure 7, which includes a control valve 71 and a vertical pipe 72. Under normal circumstances, when the high-pressure water pump 43 supplies water to the water supply pipe 44, the control valve 71 is closed. After each sewage discharge operation, the control valve 71 can be manually opened. Then, the external clean water output by the high-pressure water pump 43 will be directly poured into the vertical pipe 72. The vertical pipe 72 can be cleaned with clean water to clean the inner wall of the pipe, ensuring the service life of the pipe. The control valve 71 is fixedly connected to the lower end of the connecting pipe 42. The lower end of the control valve 71 is fixedly connected to the vertical pipe 72. The lower end of the vertical pipe 72 is threaded with an outlet pipe 73 through a connecting flange 41. The side wall of the vertical pipe 72 is connected to the other end of the sewage discharge pipe 55.

[0022] Working principle: The high-pressure flushing and sludge suction integrated cleaning device, suitable for narrow spaces, can clean sludge in relatively narrow and small wells in urban or rural areas, and then discharge the sludge for reuse. Silt layer 2 is the sludge and debris accumulated at the bottom of the narrow sludge cleaning well 1. Water inlet pipe 3 is used to connect to an external water source for high-pressure cleaning. The connecting flange 41 connects the top of the stainless steel metal connecting pipe 42 to the bottom of the water inlet pipe 3. When the high-pressure water pump 43 is powered on, it will inject external water into the water supply pipe 44. The water outlet 45 will guide the water flow in the water supply pipe 44 to the high-pressure nozzle 46 and spray it out. The high-pressure nozzle 46 vertically downwards will clear away the accumulated layer of silt and mix it into a more treatable slurry. The parallel sleeve 63 is made of aluminum alloy and is clamped on the outside of the water supply pipe 44. The support sleeve 61 is clamped on the outside of the sewage pipe 55 on the other side. The parallel sleeve 63 and the support sleeve 61 are welded together by the transverse connecting rod 62. The water supply pipe 41 and the sewage pipe 55 are set side by side and close to each other. The whole is relatively thin and can be used in deep or narrow wells. The upper connecting ring 65 and the overlapping plate 64 connect the upper part of the outside of the water supply pipe 44 and the outside of the sewage pipe 55 together. This makes it more suitable for flushing and dredging work in narrow outdoor wells. The suction hood 51 is made of plastic material in a semi-circular shape. The suction hood 51 can bring the bottom of the sewage pipe 55 close to the mud after high-pressure washing. After the suction pump 56 at the top is connected to the power supply and started, it can generate suction to suck the mud upward into the sewage pipe 55. After the waterproof motor 53 is connected to the power supply and started, it can make the metal crushing wheel 54 below rotate at high speed inside the lower end of the suction hood 51. The rotating crushing wheel 54 will crush the weeds and dead branches mixed in the mud, so that the sewage pipe 55 is less likely to be blocked by debris, protecting the sewage pipe and improving the dredging efficiency. Under normal circumstances, when the high-pressure water pump 43 supplies water to the water pipe 44, the control valve 71 is closed. After each sewage discharge operation, the control valve 71 can be manually opened. Then, the external clean water output by the high-pressure water pump 43 will directly flow downward into the vertical pipe 72. The vertical pipe 72 can be cleaned with clean water to clean the inner wall of the pipe, ensuring the service life of the pipe.
