Description

Technical Field

[0001] This invention relates to the field of water environment management technology, and in particular to a sludge removal device for water environment management. Background Technology

[0002] With the continuous advancement of urban water environment management, the dredging and management of urban rivers has received increasing attention. The silt accumulated in the river not only reduces the flood discharge capacity and water storage capacity of the river, but also releases pollutants such as nitrogen and phosphorus, leading to eutrophication and water quality deterioration, which seriously affects the health of the aquatic ecosystem. Therefore, in order to reduce the pollution of the water environment by silt, it is necessary to clean the silt at the bottom of the river regularly.

[0003] Currently, the silt removal process in river channels typically involves pumping silt from the riverbed through suction inlets and transporting it to the shore via pipelines for subsequent dewatering and treatment. However, existing silt removal equipment has the following shortcomings in practical use:

[0004] On the one hand, the silt at the bottom of the river channel often becomes hardened and clumped due to long-term deposition and compaction. Existing cleaning equipment is not convenient to pre-crush and loosen the clumped silt, which makes it easy for the clumped silt to directly block the suction port when the silt is sucked up, causing the suction to be interrupted. Frequent shutdowns are required for manual dredging, which reduces the continuity and efficiency of the dredging operation.

[0005] On the other hand, existing cleaning devices typically only have a fixed filter screen at the suction port to prevent large impurities such as stones, branches, and plastic bags in the sludge from entering the pump body and causing damage. However, during long-term continuous operation, the stones, branches, and other impurities intercepted by the filter screen will gradually accumulate and clog the filter screen holes, leading to increased suction resistance and decreased suction flow. In severe cases, it may even completely block the suction channel, requiring continuous cleaning, which seriously affects the efficiency of sludge removal. Therefore, a sludge cleaning device for water environment treatment is needed to solve the above problems. Summary of the Invention

[0006] One objective of this invention is to provide a sludge cleaning device for water environment treatment, which addresses the shortcomings of traditional sludge cleaning devices, such as the inconvenience of breaking up clumps of sludge during sludge removal, which leads to clumps of sludge clogging the suction port and affecting sludge removal work, and the need for continuous shutdown to clean the filter screen during sludge filtration to reduce clogging and thus affect sludge removal efficiency.

[0018] The beneficial effects of this invention are:

[0019] The dredging mechanism can break up the clumps in the sludge, making the dredging more effective. The filtration structure can also filter and self-clean the sludge, reducing downtime for cleaning.

[0020] Furthermore, the two sets of spiral blades on the outside of the spiral blade shaft rotate in opposite directions, cutting and breaking up the sludge clumps during rotation to prevent the sludge clumps from clogging the suction head during subsequent suction. At the same time, the two sets of spiral blades concentrate the sludge at both ends towards the middle, forming a material accumulation area in the middle, so that the subsequent suction head can suck up the material more efficiently.

[0021] Furthermore, by impacting the impeller inside the housing with water flow, the impeller drives the reciprocating screw to rotate, which in turn drives the nozzle to rotate up and down through the screw sleeve, toothed plate, and toothed sleeve. This causes the high-pressure nozzle to swing up and down in a fan shape. It is driven entirely by water flow power, achieving automatic synchronization of spraying and swinging. The impeller rotates and the nozzle swings. When the water supply stops, the swinging stops automatically without the need for additional control.

[0022] Furthermore, by having high-pressure nozzles swing back and forth in a fan shape along with the nozzle pipe, and with several high-pressure nozzles arranged at equal intervals on the outside of the nozzle pipe, the water spray coverage is large, which can cover silt layers of different depths and impact the hardened silt in layers. Compared with fixed nozzles, the silt removal effect is better and the silt removal effect is improved.

[0023] Furthermore, the filter screen intercepts impurities such as stones and branches in the sludge, preventing them from entering the slurry pump and causing wear or blockage, thus protecting the pump. When the side that intercepts impurities rotates to the bottom, the suction weakens, and the impurities fall into the collection tank by their own gravity. This is a purely physical principle that does not require scrapers or backwashing, thus completing the initial cleaning of the filter screen and achieving continuous self-cleaning.

[0024] Furthermore, by shielding the counterweight block, it automatically and vertically centers itself at the bottom of the filter cylinder under its own weight, which can continuously shield the suction force at the bottom of the filter cylinder. The rotational power of the fan blades comes from the kinetic energy of the sludge water flowing inside the installation groove. The energy is taken from the working medium itself and no additional power source is required. The design of the eccentric wheel, return spring and connecting rod converts the rotational motion of the fan blades into the periodic reciprocating impact of the vibrating block, which vibrates the filter screen at the bottom of the filter cylinder and shakes off the stones and branches that have not fallen off, realizing automatic and continuous secondary cleaning. This forms a dual cleaning mechanism with the gravity-assisted primary cleaning, making its cleaning effect better.

[0025] Furthermore, a cleaning plate is used to clean the bottom of the filter cylinder again, removing any remaining impurities. This secondary cleaning keeps the mesh clear, ensuring a stable filtration area and suction flow rate, preventing a decrease in suction power due to filter clogging.

[0026] Furthermore, a torsion spring is used to make one end of the cleaning plate obliquely downward and adhere to the bottom surface of the filter cylinder. When the cleaning plate wears, it automatically adapts to the position of the filter cylinder, realizing adaptive adhesion and automatic wear compensation, thus completing the automatic cleaning of the filter cylinder and reducing downtime for cleaning.

[0046] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0047] refer to Figure 1 — Figure 10

[0048] In this embodiment, a sludge cleaning device for water environment treatment according to an embodiment of the present invention includes a sludge cleaning device 1 and a sludge cleaning head 2;

[0049] The sludge cleaning device 1 has a sludge cleaning head 2 at its front end and a slurry pump 4 at its top. One end of the slurry pump 4 is connected to the top of the sludge cleaning head 2. The sludge cleaning head 2 has a sludge cleaning mechanism 3 at its front end. The sludge cleaning mechanism 3 includes a spiral blade shaft 31, which is located inside the front end of the sludge cleaning head 2. A hydraulic motor 32 is located on the outer side of the middle of the spiral blade shaft 31. A spray pipe 33 is located at the top of the front end of the sludge cleaning device 1. A reciprocating rotating component 34 is located at one end of the spray pipe 33.

[0050] The spiral blade shaft 31 has a water passage hole inside. One end of the spiral blade shaft 31 is provided with a connecting water pipe 35. One end of the connecting water pipe 35 is rotatably sealed to the spiral blade shaft 31. The other end of the spiral blade shaft 31 is rotatably sealed to a water inlet pipe 37 and is provided with a main drive disc 38 on the outside. A sealing shell 36 is provided on the outside of the main drive disc 38.

[0051] Two sets of spiral blades are provided on the outer side of the spiral blade shaft 31. The two sets of spiral blades are symmetrically distributed on the outer side of both ends of the spiral blade shaft 31. The arrangement of the two sets of spiral blades can gather the sludge towards the middle to facilitate subsequent sludge suction.

[0052] The reciprocating rotary assembly 34 includes a mounting box 341, which is bolted to both sides of the front end of the sludge removal head 2. A reciprocating lead screw 346 is provided inside the mounting box 341. A threaded sleeve 345 is sleeved on the outside of the reciprocating lead screw 346. A toothed plate 348 is fixed on one side of the threaded sleeve 345. A limit block is provided on the other side of the threaded sleeve 345. A limit groove is provided on one side inside the mounting box 341. The limit block and the limit groove form a limit structure. The limit structure can prevent the threaded sleeve 345 from spinning freely.

[0053] The mounting box 341 is equipped with a spray pipe 33. A high-pressure nozzle 349 is provided at the front end of the spray pipe 33. A toothed sleeve 347 is provided on the outer side of one end of the spray pipe 33. The toothed plate 348 and the toothed sleeve 347 mesh with each other. The high-pressure nozzle 349 can swing up and down in a fan shape around the horizontal axis. The up and down fan shape swinging setting can make the area of ​​water sprayed by the high-pressure nozzle 349 wider.

[0054] The bottom of the mounting box 341 is provided with a mounting shell 342. An impeller 344 is provided inside the mounting shell 342. A water outlet 343 is provided on one side of the impeller 344. One end of the water outlet 343 is rotatably sealed to one end of the spray pipe 33. The other side of the mounting shell 342 is connected to one end of the water inlet pipe 37.

[0055] Several high-pressure nozzles 349 are provided, and the several high-pressure nozzles 349 are arranged at equal intervals on the outside of the nozzle 33. The arrangement of several high-pressure nozzles 349 can make the water spray area wider.

[0056] Working principle: When cleaning river silt, the connecting water pipe 35 is connected to the external high-pressure water pipe, and the external hydraulic system starts the hydraulic motor 32. After the hydraulic motor 32 starts, it drives the spiral blade shaft 31 to rotate. During the rotation of the spiral blade shaft 31, the spiral blades on its outer side cut the silt clumps and break them up, preventing the silt clumps from clogging the suction head in the subsequent suction process. There are two sets of spiral blades with opposite rotation directions. When rotating, they both convey the material to the middle, thereby concentrating the silt at both ends to the middle and forming a material accumulation area in the middle, so that the subsequent suction head can suck up the material more efficiently.

[0057] When the spiral impeller shaft 31 rotates, the connecting water pipe 35 delivers water through the interior of the spiral impeller shaft 31 to the interior of the water inlet pipe 37. The water inlet pipe 37 then delivers the water to the interior of the mounting housing 342. The water flow's power impacts the impeller 344, causing it to rotate. This is entirely driven by water flow power and requires no additional motor, hydraulic motor, or cylinder. The water flow is delivered through the outlet 343 on one side of the mounting housing 342 to the interior of the spray pipe 33. The water flow inside the spray pipe 33 is sprayed out through the high-pressure nozzle 349, spraying the sludge at the front end of the sludge removal head 2. When the high-pressure nozzle 349 sprays, the top of the impeller 344 is connected to the bottom of the reciprocating screw 346, so the impeller 344 can rotate, driving the reciprocating screw 346 to rotate. During the rotation of the reciprocating screw 346, it drives the toothed plate 348 to move up and down reciprocally through its cooperation with the threaded sleeve 345. During the reciprocating movement, the nozzle 33 rotates up and down through meshing with the toothed sleeve 347, indirectly driving the high-pressure nozzle 349 to flush the sludge in front in a reciprocating fan-shaped oscillation, breaking up the clumps of sludge. This achieves automatic synchronization between spraying and oscillation. As long as water enters the nozzle 33 from the outlet 343 of the mounting housing 342 and is sprayed out from the high-pressure nozzle 349, the impeller 344 rotates and the nozzle 33 oscillates. When the water supply stops, the oscillation automatically stops. Water enters the mounting housing 342 from inside the spiral blade shaft 31 through the connecting water pipe 35 and the inlet water pipe 37. No additional external water pipes are needed, and the pipes are not exposed, reducing the risk of entanglement and damage. The high-pressure nozzle 349 oscillates up and down in a fan-shaped oscillation with the nozzle 33. The fan-shaped reciprocating flushing has a large coverage area and can cover sludge layers of different depths, impacting the clumps of sludge in layers. Compared with fixed nozzles, it has a better sludge removal effect.

[0058] refer to Figure 11 — Figure 17

[0059] In this embodiment, a filter structure 5 is provided at the rear end of the sludge removal head 2. The filter structure 5 includes a mounting frame 51, which is installed on one side inside the sludge removal head 2. A filter screen cylinder 52 is provided inside the filter structure 5, and a collection groove 54 is provided at the bottom end inside the mounting frame 51.

[0060] The filter cylinder 52 is provided with a drive disc 55 at one end, which is connected to the main drive disc 38 via a belt. A cleaning assembly 53 is provided on one side inside the mounting frame 51. The cleaning assembly 53 includes a cleaning plate 531, which is located on one side inside the mounting frame 51.

[0061] The cleaning plate 531 is provided with fixing rods 532 at both ends. A sealing box 534 is provided on the outside of the fixing rod 532. One side of the sealing box 534 is fixed to one side of the inside of the mounting bracket 51. A torsion spring 533 is provided on the outside of the fixing rod 532. One end of the torsion spring 533 is fixed to the outside of the fixing rod 532, and the other end of the torsion spring 533 is fixed to one side of the inside of the sealing box 534.

[0062] The filter cylinder 52 is internally equipped with a vibration assembly 56, which includes a fixed shaft 564 fixed inside the filter cylinder 52. The fixed shaft 564 is movably sealed at both ends of the fixed shaft 564 with mounting sleeves 565. A blocking counterweight 561 is fixed to the bottom of the mounting sleeve 565. An installation groove 567 is formed inside the blocking counterweight 561, and a fan blade 568 is installed inside the installation groove 567. A water inlet hole 562 is formed at the front end of the installation groove 567, and a... The fan blade 568 has a water outlet 563 and a connecting shaft 569 inside. An eccentric wheel 566 is provided on the outer side of both ends of the connecting shaft 569. A connecting block 5610 is provided inside the counterweight 561 at the bottom end of the eccentric wheel 566. A connecting rod 5612 is provided at the bottom end of the connecting block 5610. A return spring 5611 is provided on the outer side of the connecting rod 5612. A vibrating block 5613 is provided at the bottom end of the counterweight 561. One end of the connecting rod 5612 is fixed to the top end of the vibrating block 5613.

[0063] Working principle: When suctioning sludge, the slurry pump 4 is driven hydraulically. The slurry pump 4 sucks up the sludge through a suction head on one side. As the sludge flows inside the sludge cleaning head 2, the rotating spiral shaft 31 drives the filter screen cylinder 52 to rotate through the cooperation of the main drive disc 38 and the driven drive disc 55. When the sludge passes through the filter screen cylinder 52, impurities such as stones and branches in the sludge adhere to the surface of the filter screen cylinder 52 due to suction and are intercepted by the filter screen cylinder 52. Rotating downwards, when the side containing stones and branches reaches the bottom, the suction at the bottom of the filter cylinder 52 weakens due to the obstruction of the counterweight 561. When the suction weakens, the stones, branches, and other impurities fall into the collection tank 54 due to the centrifugal force of the rotating filter cylinder 52 and their own gravity. This is a purely physical principle, an indirect cleaning without scrapers or backwashing, which does not damage the filter surface. The cleaning process is continuous and uninterrupted, thus completing the initial cleaning of the filter cylinder 52.

[0064] When the filter cylinder 52 rotates, it drives the fixed shaft 564 inside to rotate synchronously. Since the mounting sleeve 565 and the fixed shaft 564 are connected by a rotary seal, under the gravity of the blocking counterweight 561, the fixed shaft 564 rotates freely inside the mounting sleeve 565, and the mounting sleeve 565 does not rotate with it. Since the blocking counterweight 561 is heavy, it automatically and vertically centers at the bottom of the filter cylinder 52 under its own gravity, blocking the bottom of the filter cylinder 52, reducing the suction at the bottom of the filter cylinder 52, and helping stones and branches to fall off the surface of the bottom of the filter cylinder 52, thus achieving an indirect cleaning effect.

[0065] When the sludge water flows inside the filter cylinder 52, a portion of the sludge water enters the installation groove 567 through the inlet hole 562 and is then discharged through the outlet hole 563. During the flow of the sludge water inside the installation groove 567, the fan blade 568 rotates. The fan blade 568 is made of wear-resistant material and coated with a wear-resistant layer to reduce wear. When the fan blade 568 rotates, it drives the eccentric wheel 566 to rotate through the connecting shaft 569. During the rotation, the eccentric wheel 566 uses its own eccentric characteristics to squeeze the connecting block 5610 downward. During the downward movement of the connecting block 5610, it squeezes the reset spring 5611 to compress it, and pushes the vibrating block 5613 to collide with the bottom of the filter cylinder 52 through the connecting rod 5612, which vibrates the filter screen at the bottom of the filter cylinder 52, shaking off the stones and branches that have not fallen off, thus achieving secondary cleaning. The entire structure adopts a composite method of "gravity positioning and shielding plus sludge water-driven vibration", which improves the cleaning effect through primary indirect cleaning and secondary vibration cleaning.

[0066] As the filter cylinder 52 rotates, the surface of the bottom end of the filter cylinder 52 comes into contact with the cleaning plate 531. The cleaning plate 531 is held at an angle downwards against the surface of the bottom end of the filter cylinder 52 by a torsion spring 533. When the surface of the filter cylinder 52 passes by, the cleaning plate 531 performs a final cleaning of the impurities remaining on the surface of the bottom end of the filter cylinder 52, removing the impurities remaining on the surface of the filter cylinder 52, keeping the mesh unobstructed, and ensuring that the filtration area and suction flow of the filter cylinder 52 are stable. The suction will not decrease due to filter clogging. Finally, through the design of the above structure, multiple automatic cleaning operations are completed on the surface of the filter cylinder 52, resulting in better cleaning effect and reduced cleaning downtime.

[0067] The torsion spring 533 is designed so that one end of the cleaning plate 531 is attached to the bottom surface of the filter screen cylinder 52, and automatically adapts to the position of the filter screen cylinder 52 when the cleaning plate 531 is worn, so that the cleaning plate 531 adaptively attaches to the bottom surface of the filter screen cylinder 52, thereby completing the automatic cleaning of the filter screen cylinder 52 and reducing downtime for cleaning. After the sludge is sucked away by the slurry pump 4, it is transported to the transport vehicle on the shore through the conveying pipeline, thereby completing the cleaning of river sludge and the treatment of water environment.

[0068] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
