Description

Technical Field

[0001] The present invention relates to the technical field of river water purification and treatment, and in particular to a system and method for cleaning sludge at the bottom of a water intake pool. Background Art

[0002] For spinning companies, in addition to water supplied by water plants, they also use river water directly from nearby rivers through legal and compliant means. After undergoing a series of purification measures, this water is used as a production water source. The specific process for using river water is as follows: River water is introduced into a water intake pool through underground pipes, where suspended solids naturally settle, reducing the turbidity of the river water. After being buffered in the water intake pool, the water is then pumped through pipes to a fully automatic water purifier for purification. Finally, the purified water is supplied to various work sections within the factory.

[0003] At present, when water from the river is introduced, a grid or screen is installed at the entrance to remove large particles of impurities, such as leaves, plastic, etc.; and the water intake pool is generally installed with a combination of multiple water pumps and water diversion tanks that extend into the pool through water pumping pipes. Valves are installed on the outlet pipes of the water pumps and the inlet pipes of the full-automatic water purifier. By starting different numbers of water pumps, the outlet valves can be used to control the amount of water pumped, while the inlet valves can be used to control the flow of water entering the full-automatic water purifier. Generally, the water pumping pipe adopts DN200 stainless steel pipe, and its bottom is about 50 cm high from the bottom of the pool to avoid the sludge settled at the bottom of the pool from being directly pumped out from the water pumping pipe when pumping water.

[0004] However, after prolonged use, sludge gradually settles at the bottom of the intake tank, increasing in thickness. The dense texture of the sludge at the bottom allows it to cling to the tank floor with strong adhesion. While sludge near the pumping nozzle is carried away along with the water, maintaining a consistent thickness, the sludge in areas further from the pumping nozzle increases in thickness. However, the sludge in areas further from the pumping nozzle becomes increasingly thicker. Once the liquid level rises above the riverbed, water extraction efficiency decreases, and the bottom of the intake tank rises, reducing the actual water storage capacity. For example, if sludge accumulates more than 1 meter away from the pumping nozzle, the total river water storage capacity within the intake tank becomes insufficient. If the underground pipelines fail to draw in enough river water, the water in the intake tank will be drained or the water supply will be insufficient. Furthermore, the increased sludge height and lower effective water level can cause large sludge clumps to enter the pumping pipeline during normal pumping, leading to blockages in subsequent water distribution lines. Therefore, when the sludge at the bottom of the pool reaches a certain height, it needs to be cleaned. In the past, when cleaning the sludge, the pool had to be emptied, and then the workers went down to the bottom of the pool to clean the sludge with tools. It is time-consuming and labor-intensive, and it is difficult to completely remove it. At the same time, the working environment at the bottom of the pool is poor, and there are greater operational risks. However, the sludge needs to be cleaned regularly, otherwise the sludge in the pool will accumulate. Once the liquid level is higher than the river water bed level, the water extraction efficiency will decrease, which will affect the company's normal production activities; or find an external cleaning unit for professional treatment, which requires the use of relevant sludge cleaning equipment, which is difficult for general companies to replicate, and the desilting cost is high. Therefore, there is a need for a method that can effectively clean the sludge in the water intake pool after a simple modification based on the existing pipeline system. Summary of the Invention

[0021] The second purpose of this application is achieved by the following technical solution: A method for cleaning sludge at the bottom of a water intake pond, characterized in that: S1. Connect one end of the water pipe to the sewage pipe through a flange, and connect the other end to the sludge treatment tank to complete the assembly of the handheld aerator; S2. Start at least one pumping assembly and the drain valve, and close the second valve or the third valve 7 at the same time, so that the pool water is pumped out through the pumping assembly and flows out along the drain pipe into the sludge treatment tank, and the water level in the water intake tank is controlled at about 2m; S3. Insert one end of the handheld aerator into the water intake pool and simultaneously activate the regulating valve to a pressure of 0.1-0.7 MPa. Move the handheld aerator to mix the sludge from the bottom of the pool in different areas with the aerated pool water to form a muddy water suspension. Combined with the impact force of the water inlet, the sludge water is pumped out through the pumping assembly. The sludge thickness of the current area is determined by inserting the handheld aerator and contacting the sludge. S4. Gradually control the water flow at the water inlet to keep the distance between the pool water and the sludge between 0.5 and 1m. When the sludge at the bottom of the pool is determined to be less than 0.5m, control the water level below 1m. S5. When the sludge at the bottom of the pool is less than 30cm, lower the telescopic tube downwards and close the pumping assembly without the telescopic tube. Control the water level at 50-60cm for drainage. After basically judging that the sludge at the bottom of the pool has formed mixed sewage, close the water inlet to suck out all the pool water that can be sucked out. Close the handheld aerator and pumping assembly to complete the cleaning of the sludge at the bottom of the pool.

[0022] Preferably, after the first cleaning is completed, the stainless steel main pipe and the stainless steel diversion pipe are installed in the water intake pool, so that the stainless steel diversion pipe is 5 to 10 cm away from the bottom of the pool after being supported by the bracket, and the stainless steel main pipe is connected to the compressed air main pipe and closed by a valve.

[0024] Preferably, when the sludge at the bottom of the water intake pool reaches 30-40 cm, aeration is performed through the stainless steel diversion pipe at the bottom of the water intake pool to achieve cleaning of the sludge.

[0025] Preferably, when the sludge at the bottom of the water intake pool exceeds the aeration-driven thickness of the stainless steel diverter tube, it is first cleaned by a handheld aerator. When the sludge thickness reaches the aeration-driven thickness, it is quickly cleaned by the stainless steel diverter tube.

[0026] When cleaning the sludge at the bottom of the water intake pool, you can quickly connect to the existing compressed air connection in the factory area, use a pressure gauge to manually control the blowing flow, and "spirally" stir and roll the sludge at the bottom of the sedimentation pool to fully mix it with the river water to form mud and water suspension. At the same time, use a water pump to quickly pump out all the mud and water suspension to clean the water intake pool. This can directly clean the deposited sludge without emptying the water intake pool, saving manpower and time costs, and allowing flexible mobile operations to clean the sludge at the bottom of the pool in all directions. There is no need for operators to go down to the bottom of the pool to work, which can reduce the unsafe factor, reduce the possibility of hazards such as suffocation and falls, and improve inherent safety. It also improves cleaning efficiency and makes work safer.

[0027] Compared with the prior art, the present invention has the following beneficial effects: By adding a sewage pipe with a sewage valve to the water supply pipe of the existing system, and then cooperating with a handheld aerator, the sludge at the bottom of the water intake pool can be fully stirred and mixed with the pool water through the handheld aerator to form a mud-water suspension. Then, through the cooperation of the valve, the sewage is directly discharged outward through the sewage pipe and enters the sewage station, thus solving the problem that the sludge at the bottom of the existing water intake pool is difficult to clean directly because it is aggregated and has a tight texture. The operator can quickly and safely clean the sludge at the bottom of the pool without entering the water intake pool or looking for external manufacturers. The operation is simple and labor-saving. The operation is not affected by the environment in the pool and the operation is highly safe. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Below, the present application is further described in conjunction with the accompanying drawings and specific implementation methods.

Therefore, they should not be understood as limitations on this application.

[0031] The terms "first," "second," and the like in this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship. Example 1:

[0032] like Figure 1 and Figure 2 As shown, a system for cleaning sludge at the bottom of a water intake pool 1 comprises: a water intake pool 1 for caching river water introduced from a river channel 2; The pumping assembly 3 is used to pump out the river water after sedimentation and then transport it to the automatic water purifier 10 for purification. The outlet pipe of the pumping assembly 3 is provided with a first valve 4; A fully automatic water purifier 10 is used to purify water. A second valve 9 is provided on the water inlet pipe of the fully automatic water purifier 10; The water supply pipeline 8 is used to uniformly deliver the river water pumped out by each of the pumping assemblies 3 to each of the fully automatic water purifiers 10; A drain pipe 6 is installed on the water supply pipe between the pumping component 3 and the second valve 9. The drain pipe 6 is provided with a drain valve 5 and also includes a handheld aerator 20. The handheld aerator 20 is used to fully stir and mix the settled sludge in the water intake pool 1 with the pool water to form a muddy water suspension. The muddy water suspension is then pumped out through the pumping component 3 and discharged outward along the drain pipe 6.

[0033] In the actual production process, the river water in the river 2 is introduced into the water intake pool 1 through a DN700 underground pipe. The water in the water intake pool 1 is then pumped out by the pumping assembly 3 and transported to the fully automatic water purifier 10 through the water supply pipe for effective water purification, so that the outflowing water can be used in different stages of the spinning production. However, during long-term use, the water intake pool 1 will slowly deposit a large amount of sludge and other impurities. Once the sludge sediment thickness reaches more than 1 meter, it will affect the water intake in the water intake pool 1, making the total amount of available water in the water intake pool 1 fail to meet the requirements. Figure 1As shown in the diagram of the approximate distribution of sludge and water in the water intake pool 1, although the sludge does not block the water intake of the pumping assembly 3, the water volume is significantly reduced. At this time, the sludge at the bottom of the pool needs to be cleaned. To facilitate the cleaning of the sludge at the bottom of the pool, a drain pipe 6 with a drain valve 5 is installed on the water supply pipe between the pumping assembly 3 and the second valve 9. A handheld aerator 20 is also manufactured. By inserting one end of the handheld aerator 20 into the water intake tank 1, the sludge in the water intake tank 1 is aerated and then fully mixed with the tank water to form a muddy water suspension. The muddy water suspension is then extracted by the pumping assembly 3 and discharged outward along the sewage pipe 6, allowing the sewage to be discharged directly through the sewage pipe 6 and then enter the sewage treatment station. This solves the problem of the existing sludge at the bottom of the water intake tank 1 being difficult to clean directly due to its dense and clumping texture. The operator can quickly and safely clean the sludge at the bottom of the tank without entering the water intake tank 1 or seeking external manufacturers. The operation is simple and labor-saving, and the operation is not affected by the internal environment of the tank, which increases the safety of the operation. The handheld aerator 20 can be quickly and effectively moved according to the different sludge height positions, stirring and rolling the sludge in different areas of the bottom of the water intake tank 1 to form a muddy water suspension, thus achieving the effect of completely cleaning the sludge at the bottom of the tank without draining the water.

[0034] A further improvement is that the handheld aerator 20 is connected to the compressed air pipeline through an air pipe. After the handheld aerator 20 ejects a spiral airflow, the sludge at the bottom of the water intake pool 1 is stirred and rolled with the pool water to form a mud-water suspension.

[0035] Since the airflow direction of conventional aeration devices is constant, the water in the pool also flows in a straight line after aeration. Although it has a certain sludge removal effect, it can only remove the sludge corresponding to the surface flow, and the coverage area is small. Moreover, even if the aeration end is moved, it can only slowly dissolve the sludge on the surface into the pool water, making it difficult to achieve a large-scale rapid dissolution effect. Therefore, after the handheld aerator 20 is connected to the compressed air pipeline through the air pipe, the handheld aerator 20 is caused to eject a spiral airflow, so that when it is inserted into the pool water, it can drive the pool water to form a spiral flow within a certain range, thereby more effectively driving the stubborn sludge near the bottom to quickly mix with the pool water, effectively avoiding the problem that conventional aeration devices can only stir the pool water in a local area when stirring the pool water, and the water flow force is not strong enough, which makes it difficult for the agglomerated sludge to mix quickly with the pool water.

[0036] Further improvement is as follows: Figure 2 and Figure 3 As shown, the handheld aerator 20 includes a lightweight steel pipe 23 , a regulating valve 26 and a pressure gauge 27 provided at the top of the lightweight steel pipe 23 , and a spiral aeration head 22 provided at the other end of the lightweight steel pipe 23 .

[0037] The handheld aerator 20 consists of a lightweight steel pipe 23, a regulating valve 26, a pressure gauge 27, and a spiral aeration head 22. A handle 25 and a one-way regulating valve 26 are mounted on top of the lightweight steel pipe 23, making it easy to hold and move. Connected to the compressed air pipeline via a compressed air hose, the air pressure can be easily adjusted during construction, improving the flow of pool water. The spiral aeration head 22 can mix the blown air with the pool water, driving the pool water to flow in a spiral. By changing the flow trajectory, the sludge is more effectively mixed with the flowing pool water to form a mixed suspension, preventing the sludge from quickly mixing with the water. A compressed air connection is available on-site, and the compressed air is produced in-house, making it simple to manufacture. Factory personnel can perform welding work without the need for third-party assistance, saving costs. Furthermore, combining the handheld aerator with the compressed air connection is simple and quick, allowing on-site operators to complete the operation independently. This tool eliminates the need for workers to reach the bottom of the pool, reducing safety risks, minimizing the risk of suffocation, falls, and other hazards, and enhancing inherent safety. It eliminates the need to drain the pool, saving labor and time, and allows for flexible, mobile operation, enabling comprehensive cleaning of pool bottom sludge.

[0038] A handle 25 is further provided at the upper end of the lightweight steel pipe 23 , and the spiral aeration head 22 adopts a cross structure.

[0039] After the operator holds the handle 25, he can easily move the lightweight steel pipe 23, and the spiral aeration head 22 adopts a cross structure. When the spiral aeration head 22 is extended into the water intake pool 1, the high-pressure gas ejected by the spiral aeration head 22 can make the pool water produce a better rotation and stirring effect, thereby driving the sludge at the bottom of the pool and the pool water to form a mud-water suspension. By moving the position of the spiral aeration head 22, the sludge in various areas of the water intake pool 1 can be quickly mixed with the pool water, so that the sludge settled at the bottom of the pool can be pumped out through the pumping component 3. During the entire operation, the operator only needs to stand on the water intake pool 1 to control the liquid level of the water intake pool 1 and observe the situation of the sludge and move the handheld aerator 20 to achieve effective cleaning of the sludge in different areas, so that the sludge far away from the water pumping port can also be effectively cleaned. During the entire operation, the operator does not need to enter the water intake pool 1, nor does it need to use any additional pumping equipment and instruments, so that the sludge at the bottom of the water intake pool 1 is easy and convenient to clean, and is no longer affected by the working environment at the bottom of the pool, and the operation is highly safe.

[0040] A further improvement is that the spiral aeration head 22 includes a connecting seat 30 threadedly connected to the lightweight steel pipe 23, an aeration pipe 21 arranged in a cross structure on the connecting seat 30, and an aeration hole 28 provided on the aeration pipe 21, and the aeration hole 28 is arranged at an angle of 45° to 50°.

[0041] Compressed air is ejected outward through the aeration holes 28 obliquely arranged on the aeration tube 21, which can make the water flow more intensely stirred, and the flow direction of the water flow produces a spiral flow with each aeration tube 21 as the axis. When cleaning the sludge, the sludge can be mixed with the water and then flow upward quickly, thereby improving the sludge cleaning effect; the entire handheld aerator 20 is simple to manufacture and low in cost; it reduces manual operation time, improves work efficiency, and at the same time increases the safety factor of the operation.

[0042] When the aeration tube 21 adopts a cross star shape, it is installed at a 45° clockwise tilt, and the aeration hole 28 is generally 5mm. When in use, the sludge at the bottom of the pool and the pool water can be effectively mixed without emptying the pool, which can save manpower and time costs, and can be flexibly moved and operated to clean the sludge at the bottom of the pool in all directions. There is no need for operators to go down to the bottom of the pool to work, which can reduce the safety factor, reduce the possibility of hazards such as suffocation and falls, and improve inherent safety.

[0043] A further improvement is that the connecting seat 30 is connected to the lightweight steel pipe 23 through a bearing seat 31, the aeration tube 21 is arranged in an arc shape, and an aeration push hole 29 is provided at the outer end of the aeration tube 21. The spiral aeration head 22 located in the pool water sprays high-pressure air outward through the aeration push hole 29 to form a spiral driving force, driving the connecting seat 30 to rotate along the bearing seat 31.

[0044] Although the pool water and sludge can be mixed in rotation after the rotary aeration is performed by high-pressure gas, it is difficult to form a flowing water flow quickly and over a large area with a simple spiral distribution of airflow, especially it is difficult to form a vortex-shaped water flow structure. The airflow direction of the aeration device is constant, and the water flow depth that can be driven is low, resulting in the sludge removal efficiency cannot be further improved. Therefore, in order to improve the sludge removal efficiency, the aeration pipe 21 is bent into an arc to form a propeller structure, and then the aeration push of the bearing seat 31 and the outer end can be used to drive the entire spiral aeration head 22 to rotate and aerate through the bearing seat 31 through the push of the airflow. By appropriately increasing the local After the aeration holes 28 are opened, the airflow required in the rotation direction is greater than the airflow in other areas, and it can also play a role in assisting the rotation. When the compressed air is blown out from the spiral aeration head 22, it can not only drive its rotation through the airflow, but also drive the water flow to rotate, so that when it is extended into the pool water, it can drive the pool water to form a spiral flow within a certain range, thereby more effectively driving deeper and wider pool water and the stubborn sludge at the bottom to mix quickly with the pool water, effectively avoiding the problem that conventional aeration devices can only mix and stir the sludge in the surface area when stirring the pool water, and the water flow force is not strong enough, resulting in the agglomerated sludge being difficult to mix quickly with the pool water.

[0045] A further improvement is that the spiral aeration head 22 includes a plurality of 1.5-2.5 m lightweight steel pipes 23, a connecting pipe 24 is provided between two adjacent lightweight steel pipes 23, and the lightweight steel pipe 23 and the connecting pipe 24 are connected by threads.

[0046] Generally, the water level depth of the water intake pool 1 is about 3 meters, and the overall depth of the water intake pool 1 is about 5 meters. Although it is simple to directly make a single lightweight steel pipe 23, it is troublesome to store and store, and it is also troublesome to move when not in use. Moreover, the pipe diameter is too large, which easily causes an increase in the overall total amount. Therefore, the lightweight steel pipe 23 adopts a DN20 steel pipe with a length of 1.5~2.5m, and each pipe is generally about 2m. The two adjacent lightweight steel pipes 23 are connected by a connecting pipe 24, wherein the connecting pipe 24 is an internally threaded pipe. After the two are connected by threaded connection, effective sealing can be achieved. Generally, the shorter the connecting pipe 24, the better, the overall weight is lighter, the flexibility of increasing or decreasing the length is higher, it is more convenient to hold, and it is more labor-saving to move the spiral aeration head 22. It has good rigidity and is not easy to be damaged. Moreover, it is simpler and more convenient to assemble and store, and there will be no situation where there is nowhere to put it due to excessive length.

[0047] A further improvement is that the pumping assembly 3 includes a pumping pipe 33, a water diversion tank 32, and a water pump 31. One end of the pumping pipe 33 extends into the water intake pool 1. The outside of at least one of the pumping pipes 33 is provided with a liftable telescopic tube 15. After the pumping pipe 33 is lengthened by the telescopic tube 15, it is less than 15 cm away from the bottom of the pool.

[0048] Since the bottom of the pumping pipe 33 of the existing pumping assembly 3 is at a height of about 0.5m from the bottom of the pool, it is difficult to clean the sludge in the water intake pool 1 during the cleaning process, even if the sludge is completely stirred into a mixed liquid, resulting in a layer of thick precipitated sludge quickly formed after the cleaning is completed. Therefore, in order to enable the sludge to be thoroughly cleaned, a telescopic tube 15 that can be raised and lowered is installed on one or more of the pumping pipes 33. During normal use, the telescopic tube 15 is sleeved on the outside of the pumping pipe 33, and the bottom of the pumping pipe 33 is at a height of about 0.5m. The degree remains unchanged. When the sludge is cleaned to a certain extent, after closing the water inlet of the river 2, the telescopic tube 15 can be moved downward so that the lower end of the telescopic tube 15 is less than 15 cm from the bottom of the pool. When draining water, the water level can be directly controlled to about 60 cm. Through the combined operation of pumping + water inlet + aeration, it can ensure that the sewage is discharged as much as possible, and the sludge content remaining in the pool water can be made to reach the bottom of negligible. When the water level is controlled below 40 cm, the bottom sludge can be quickly pumped out, thereby achieving the purpose of thoroughly cleaning the sludge.

[0049] As a further improvement, the lower end of the water pumping pipe 33 is provided with a circular metal ring 16, and the upper end of the telescopic tube 15 is provided with an inwardly protruding stop ring 13.

[0050] When installing the telescopic tube 15, a circular metal stop ring 13 is welded to the upper end of the telescopic tube 15. The inner diameter of the stop ring 13 is larger than the outer diameter of the water pumping pipe 33 and smaller than the outer diameter of the metal ring 16. The length of the telescopic tube 15 is generally 40~45cm. During assembly, the telescopic tube 15 is first put onto the water pumping pipe 33 from the bottom upward, and then a metal ring 16 is installed at the pipe mouth of the water pumping pipe 33. The metal ring 16 is generally connected by welding or bolting. After assembly is completed, the downwardly descending telescopic tube 15 can be stopped and sealed, thereby achieving the purpose of extension. The structure is simple, the operation is highly practical, and the installation is convenient.

[0051] As a further improvement, at least two lifting rings 14 are provided in a ring shape on the metal holding ring 16 , and a lifting chain 11 is provided on the lifting ring 14 .

[0052] After fixing one end of the lifting chain 11, the telescopic tube 15 can be slid upward and positioned outside the water pumping pipe 33. When needed, it can be unlocked and lowered. Generally, one end of the lifting chain 11 is connected to a motor, which can drive the movement of the lifting chain 11 to control the lifting, which is safer and less labor-intensive. It can also be connected to a crane and can even be directly controlled manually after installing a pulley block.

[0053] As a further improvement, the water supply pipeline 8 is provided with a pipeline mixer 82 , a filter 83 and a flow meter 84 , and the pipeline mixer 82 is provided with a reagent adding valve 81 .

[0054] By adding a pipeline mixer 82, a filter 83 and a flow meter 84 to the water supply pipeline 8, the flow rate can be monitored in real time, and impurities can be preliminarily filtered and removed through the filter 83, thereby reducing the purification cost of the fully automatic water purifier 10. In particular, after a pipeline mixer 82 with a chemical addition valve 81 is added before the filter 83, by adding chemicals at the inlet end of the pipeline mixer 82, the suspended matter in the water can be quickly condensed, so that the filter 83 can filter more particles.

[0055] A further improvement is that the chemicals added into the pipeline mixer 82 through the chemical adding valve 81 are coagulants and flocculants.

[0056] Before entering the filter 83, adding coagulants and flocculants into the pipeline mixer 82 can make the fine particles directly condense into larger flocs before entering the filter 83, thereby facilitating the filtering and cleaning of fine particles in the filter 83 and facilitating subsequent separation, reducing the purification burden of the fully automatic water purifier 10, and extending the service life of the fully automatic water purifier 10 and achieving better purification effects. Especially after adding the flocculant, in combination with the multi-layer material filter 83 or the shallow sand filter 83, the flocculant can further remove suspended matter and some microorganisms in the pipeline mixer 82, and some flocculants that enter the filter 83 along the water flow can also be blocked by the filter 83 and then effectively flocculated again in the filter 83, thereby more thoroughly achieving the removal of suspended matter and some microorganisms.

[0057] As a further improvement, one end of the sewage pipe 6 is provided on the water supply pipeline 8 between the pipeline mixer 82 and the first valve 4 , and a third valve 7 is further provided on the sewage pipe 6 .

[0058] When sewage needs to be discharged, by opening the sewage valve 5 and closing the third valve 7 at the same time, the sewage can be discharged without passing through the pipeline mixer 82 and the filter 83 for cleaning, thereby avoiding the sludge in the sewage from frequently clogging the filter 83 when discharging sewage, and effectively avoiding the disassembly and cleaning operation of the filter 83.

[0059] A further improvement is that the bottom of the water intake pool 1 is provided with a plurality of stainless steel diversion pipes 17 with aeration holes 28 and a stainless steel main pipe 12 for supplying air to the plurality of stainless steel diversion pipes 17 , and the stainless steel diversion pipes 17 are 5 to 10 cm away from the bottom of the water intake pool 1 .

[0060] After the sludge and pool water in the water intake pool 1 are drained, a stainless steel diversion pipe 17 and a stainless steel main pipe 12 composed of 304 stainless steel pipes are installed. The stainless steel main pipe 12 is embedded in the pool wall of the water intake pool 1 and extends downward, and then is connected to each stainless steel diversion pipe 17 through a horizontal pipe. The bottom of the stainless steel diversion pipe 17 is supported by a bracket and is 5 to 10 cm away from the bottom of the pool. Generally, the stainless steel diversion pipe 17 adopts DN20. The holes on the stainless steel diversion pipe 17 are distributed in a ring shape, and the aperture is generally about 5 mm. The stainless steel main pipe 12 is connected to the compressed air main through a valve. Under normal circumstances, the valve is closed. When thoroughly cleaning the sludge, when the water level or water reserve reaches a certain lower limit, the problem of not cleaning the sludge and the pool water being insufficient, requiring water to be added again, will not occur. However, when the sewage in the water intake pool 1 drops to a certain height, for example, about 30 cm from the pool bottom, if the sludge at the bottom is allowed to fully and quickly mix with the pool water, it is easy to cause poor water level control, resulting in the sewage being completely discharged while the sludge is still retained over a large area. Therefore, when the sludge in the water intake pool 1 drops to a certain level, the valve is opened to allow compressed air to be discharged from the aeration holes 28 on the stainless steel diverter pipe 17, thereby quickly and comprehensively promoting the mixing of the sludge and water, thereby quickly achieving a one-time rapid stirring of the sludge below 15 cm at the pool bottom, thereby avoiding the problem of excessive drainage and the handheld aerator 20 not having enough time to aerate the sludge at the bottom. Example 2:

[0061] A method for cleaning sludge at the bottom of a water intake pool, S1. Connect one end of the water pipe to the sewage pipe 6 through a flange, and connect the other end to the sludge treatment tank to complete the assembly of the handheld aerator 20; S2. Start at least one pumping assembly 3 and the drain valve 5, and simultaneously close the second valve 9 or the third valve 7, so that the pool water is pumped out through the pumping assembly 3 and flows out along the drain pipe 6 into the sludge treatment tank, and the water level in the water intake tank 1 is controlled at about 2m; S3. Insert one end of the handheld aerator 20 into the water intake pool 1 and simultaneously activate the regulating valve 26 to a pressure of 0.1-0.7 MPa. Move the handheld aerator 20 to mix the sludge from the bottom of the pool in different areas with the aerated pool water to form a muddy-water suspension. Combined with the impact force of the water inlet, the sludge water is pumped out through the pumping assembly 3. The sludge thickness of the current area is determined by the handheld aerator 20 inserting and contacting the sludge. S4. Gradually control the water flow at the water inlet to keep the distance between the pool water and the sludge between 0.5 and 1m. When the sludge at the bottom of the pool is determined to be less than 0.5m, control the water level below 1m. S5. When the sludge at the bottom of the pool is less than 30 cm, lower the telescopic tube 15 downwards and close the pumping assembly 3 without the telescopic tube 15 installed. Control the water level at 50-60 cm for drainage. After basically judging that the sludge at the bottom of the pool has formed mixed sewage, close the water inlet to suck out all the pool water that can be sucked out, close the handheld aerator 20 and the pumping assembly 3, and complete the cleaning of the sludge at the bottom of the pool.

[0062] When the existing water intake pool 1 is thoroughly cleaned for the first time, the compressed air connection port in the factory area is quickly connected, and the blowing flow of the handheld aerator 20 is manually controlled by the pressure gauge 27, so that the sludge at the bottom of the sedimentation pool is "spirally" stirred and rolled, and fully mixed with the river water to form muddy water suspension. At the same time, the water pump 31 is used to quickly pump out all the muddy water suspension to clean the water intake pool 1. In the early stage, the impact force and fluidity generated by the mobile aeration of the handheld aerator 20 and the water level drop of the water inlet are used to quickly pump out the aerated suspended sludge water by the pumping component 3. By quickly extending the handheld aerator 20 to the bottom and moving it, it can The water level can be roughly determined to determine the current sludge thickness. When the thickness decreases, the water level is slowly lowered so that the impacting water flow can always impact the pool water, allowing the sludge water to be pumped out more quickly by the pumping assembly 3. When the sludge thickness at the pool bottom is less than 30 cm, the excessive amount of pool water can easily cause the sludge content in the discharged pool water to be seriously reduced, thereby reducing the sludge drainage effect. Therefore, the water level is controlled at approximately 50-60 cm, and the telescopic tube 15 is lowered. This not only ensures the sludge concentration after aeration in the pool water, but also avoids the problem of surrounding air being sucked in due to excessive suction force of the pumping assembly 3, ensuring the safe operation of the pumping pump 31. In particular, when it is basically determined that the sludge at the pool bottom has basically formed muddy water, the water inlet can be closed, allowing the internal pool water to be basically sucked out by the telescopic tube 15, so that the pool water remaining at the bottom of the pool is less than 15 cm. The sludge in this part of the pool water can be basically ignored, thereby ensuring the thorough cleaning of the sludge at the pool bottom. It can achieve the purpose of directly cleaning the deposited sludge without emptying the water intake pool 1, saving manpower and time costs, flexible mobile operation, and all-round cleaning of the sludge on the bottom of the pool; and there is no need for operators to go down to the bottom of the pool to work, which can reduce the unsafe factor, reduce the possibility of hazards such as suffocation and falls, and improve inherent safety; improve cleaning efficiency, and be safer at work.

[0063] A further improvement is that after the first cleaning is completed, the stainless steel main pipe 12 and the stainless steel diversion pipe 17 are installed in the water intake pool 1, so that the stainless steel diversion pipe 17 is 5 to 10 cm away from the bottom of the pool after being supported by the bracket, and the stainless steel main pipe 12 is connected to the compressed air main pipe and closed by a valve.

[0064] To ensure greater convenience in cleaning the sludge at the bottom of the pool in the later stages, the water level in the water intake pool 1 is very low after the first cleaning, providing a direct environment for the installation of the stainless steel main pipe 12 and the stainless steel diverter pipe 17. In this state, the stainless steel main pipe 12 and the stainless steel diverter pipe can be installed completely. During installation, the stainless steel main pipe extends downward along the side wall of the water intake pool 1. The upper end is connected to a valve connection port with compressed air in the factory area through a pipe, while the lower end is diverted through a horizontal pipe, allowing gas to enter each stainless steel diverter pipe. The stainless steel diverter pipe 17 is supported by a bracket and is 5 to 10 cm from the pool bottom. The aeration holes 28 are generally 5 mm micropores. The installation of the stainless steel main pipe 12 and the stainless steel diverter pipe 17 is simple and convenient. After installation, in order to clean the sludge again, it is only necessary to control the sludge thickness to a level that can be directly aerated from the bottom to form muddy water. The handheld aerator 20 is no longer required, and the operation can be achieved by simply using the telescopic tube 15.

[0065] A further improvement is that it takes a long time for the sludge to settle. Therefore, when cleaning the sludge at the bottom of the water intake pool 1 installed with the stainless steel main pipe 12 and the stainless steel diversion pipe 17, the pumping assembly 3 is opened regularly, the drain valve 5 and the valve on the stainless steel main pipe 12 are opened, and the second valve 9 or the third valve 7 is closed at the same time. After opening the air inlet valve, the stainless steel diversion pipe 17 can directly aerate the sludge at the bottom of the pool over a large area, so that the sludge at the bottom of the pool and the pool water can be quickly mixed. After reducing the water flow at the water inlet to keep the pool water at about 1m for a certain period of time, the sludge at the bottom of the pool can be discharged over a large area. After cooperating with the telescopic pipe 15 and the water level, the sludge at the bottom of the pool can be quickly cleaned. During the cleaning process, the total amount of sludge can be judged by observing the turbidity of the aerated state of the pool water, thereby determining whether the sewage discharge work is completed, so that sewage discharge can be a regular operation of the enterprise, and safe cleaning of the sludge at the bottom of the pool can be achieved without the use of external objects.

[0066] Among them, the thickness of the sludge can be roughly judged based on experience or by lowering the water level or measuring with tools. When the sludge at the bottom of the water intake pool 1 reaches 30~40cm, the stainless steel diversion pipe 17 at the bottom of the water intake pool 1 is opened for aeration to achieve sludge cleaning and effectively prevent sludge accumulation from affecting water quality.

[0067] When the sludge at the bottom of the water intake pool 1 exceeds the aeration-pushing thickness of the stainless steel diverter pipe 17 due to poor water quality or long-term forgetting to clean it, generally when the sludge thickness exceeds 40 cm, it is difficult to push the sludge by aeration directly through the stainless steel diverter pipe 17. Therefore, it is only necessary to use the handheld aerator 20 to quickly clean the surface. When the sludge thickness reaches the aeration-pushing thickness, the stainless steel diverter pipe 17 is used to quickly clean the sludge to complete the operation. The operation is less difficult and more efficient. Especially when the two are combined, when the local area reaches the aeration range of the stainless steel diverter pipe 17, a chain reaction can be triggered, making the mixing efficiency of the sludge at the bottom of the pool and the pool water higher.

[0068] The above-mentioned embodiments are only preferred embodiments of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and replacements made by technicians in this field based on the present application shall fall within the scope of protection required by the present application.
