Description

Technical Field

[0001] The present invention relates to the technical field of silt clearing equipment, in particular to silt processing equipment for water conservancy silt clearing. Background Art

[0002] Hydraulic desilting is a crucial engineering measure that involves removing silt from the bottom of rivers, lakes, reservoirs, and other water bodies through manual or mechanical means to restore water function, improve the ecological environment, and ensure flood control and drainage safety. Its core goal is to address issues such as reduced flood discharge capacity, deteriorating water quality, and ecosystem degradation caused by siltation, while also exploring ways to recycle silt as a resource, achieving both economic and ecological benefits.

[0003] After searching, the Chinese patent with the announcement number CN117510023B discloses a sewage and sludge treatment equipment for desilting lakes and reservoirs and land reclamation, which includes a support assembly, an outer cover assembly, a drive assembly, a spiral extrusion assembly, a support assembly, a conductive assembly and a protective stirring assembly. The outer cover assembly is provided on the top of the support assembly, and the support assembly includes a partition plate, a support seat, a support member and two telescopic members. The outer cover assembly is used to prevent users from getting close and getting injured. The drive assembly is used to drive the spiral extrusion assembly to rotate. The spiral extrusion assembly is used to transport sludge and sewage, and cooperate with the support assembly to squeeze the sludge, so that the sewage in the sludge is separated. The support member of the support assembly is used to cooperate with the spiral extrusion assembly to squeeze the sludge. The telescopic member is used to expand the discharge space, making the discharge space larger and improving the dehydration efficiency, and starting the conductive assembly to make the protective stirring assembly operate and clear the discharge space. However, when this solution is actually used, there are still the following shortcomings:

[0004] The above-mentioned equipment can effectively dredge the discharge space through the cooperation between various components. However, when treating sludge, the sludge needs to flow through a filter device specially provided on the inside of the outer shell to achieve dehydration treatment, thereby reducing the water content of the sludge and facilitating subsequent transportation, storage or further processing and utilization. However, since the composition of sludge is extremely complex, it not only contains a large number of soil particles, but may also be mixed with various organic matter, inorganic matter, debris and tiny particulate matter. These complex substances are very easy to adhere to the filter screen, filter holes and other parts of the filter device when passing through the filter device. As time goes by and the amount of sludge treated continues to increase, they will gradually accumulate and form blockages, seriously affecting the normal filtering function of the filter device, resulting in a significant decrease in dehydration efficiency, and may even make the entire sludge treatment system unable to operate normally. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: in the existing technology, sludge needs to be dehydrated through the filtering device inside the shell. However, the sludge is complex in composition, containing soil, organic matter, debris, etc., and is easily attached to the filter screen and filter holes of the filtering device to form blockage, seriously affecting the dehydration efficiency and even making the system unable to operate normally.

[0018] Technical effects and advantages of the present invention:

[0020] In the present invention, when the rotating sleeve rotates, the driving block moves the abutment block, driving the guide block, the support plate and the flushing nozzle to rotate. When the abutment block reaches the yielding port, it resets to realize reciprocating rotation. This design enables the flushing nozzle to cover a large area of ​​the filter sleeve. Combined with the high-pressure water flow, it can thoroughly remove impurities and dirt remaining on the outer wall. When the device is turned on when not performing sludge treatment, the filter sleeve can be cleaned in time to avoid the accumulation of impurities affecting the filtering effect, further ensuring the cleanliness and efficient operation of the equipment and extending the service life of the equipment.

[0021] In the present invention, when the shift rod drives the shift block to make the filter sleeve slide and compress the spring 2, the spring 2 rebounds during separation to make the filter sleeve vibrate. This vibration can loosen the impurities on the outer wall of the filter sleeve and vibrate them off. When used in conjunction with the flushing nozzle and the cleaning scraper, a multi-level cleaning mechanism is formed, which plays its respective role at different stages, jointly ensuring the filtering effect of the filter sleeve, improving the sludge treatment efficiency, and enabling the equipment to maintain good performance when treating sludge with complex components, thereby improving the adaptability and reliability of the equipment.

[0033] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0034] Reference Figure 1-3 As shown, the present invention provides a technical solution: a sludge treatment equipment for water conservancy dredging, comprising a casing 11 and a spiral extrusion roller 12 rotatably mounted on the inner side of the casing 11, a filter sleeve 13 corresponding to the spiral extrusion roller 12 is provided on the inner side of the casing 11, a driving motor 14 with an output end fixedly mounted on one end of the casing 11 and fixedly connected to the end of the spiral extrusion roller 12, a discharging structure 15 is provided on the end of the casing 11 away from the driving motor 14, a supporting sleeve 31 is fixedly mounted on the inner wall of the casing 11 close to the driving motor 14, and the filter sleeve 13 is slidably connected to the inner wall of the supporting sleeve 31, a fixing ring 32 is fixedly sleeved on the outer wall of the supporting sleeve 31, a feeding pipe 21 is penetrated on the upper part of the outer wall of the end of the casing 11 away from the discharging structure 15, and the feeding pipe 21 is connected to the supporting sleeve 31, and a liquid outlet pipe 22 is penetrated on the lower part of the outer wall of the end of the casing 11 away from the feeding pipe 21.

[0035] First, the casing 11 can be erected so that the sewage collection box and the sludge collection box are located directly below the liquid outlet pipe 22 and the discharge structure 15 respectively. The casing 11 connects the feeding pipe 21 with the sludge feeding pipe. The sludge can enter the support sleeve 31 through the feeding pipe and the feeding pipe 21 and contact the spiral extrusion roller 12. When the drive motor 14 is turned on, the spiral extrusion roller 12 can be driven to rotate. When the spiral extrusion roller 12 rotates, the sludge can be transported. During the transportation process, the closer the spiral extrusion roller 12 is to the discharge structure 15, the closer the distance between its blades is. Therefore, the sludge can be squeezed during the transportation process. When the sludge is squeezed, the sewage inside it can pass through the filter sleeve 13 and be discharged to the inner side of the casing 11, and can be discharged to the sewage collection tank along the liquid outlet pipe 22. The sludge after dehydration can enter the sludge collection tank through the discharge structure 15.

[0036] Reference Figure 3 、 Figure 4 、 Figure 5 and Figure 7 As shown, an anti-blocking assembly is provided on the side of the fixing ring 32, and the anti-blocking assembly includes a toothed ring 34 provided on the side of the fixing ring 32. A cleaning scraper 35 corresponding to the filter sleeve 13 is fixedly mounted on the inner wall of the toothed ring 34. Bristles 36 are provided on the side of the cleaning scraper 35. A supporting structure corresponding to the toothed ring 34 is provided on the side of the fixing ring 32.

[0037] The supporting structure includes a rotating sleeve 33 rotatably mounted on the side of the fixed ring 32, and the gear ring 34 is fixedly connected to the rotating sleeve 33. A mounting port is opened at the end of the supporting sleeve 31, and the filter sleeve 13 is slidingly connected to the inner wall of the mounting port, and the supporting sleeve 31 is flush with the inner wall of the filter sleeve 13. A shaft 41 is provided through the side of the fixed ring 32, and a driving gear 42 meshing with the gear ring 34 is fixedly mounted on one end of the shaft 41. The other end of the shaft 41 passes through the side of the casing 11 and is fixedly mounted with a driven wheel 43 on the outer wall of the output end of the drive motor 14. The two driven wheels 43 are connected by a synchronous belt transmission.

[0038] When the driving motor 14 drives the spiral extrusion roller 12 to rotate, it can drive the shaft 41 to rotate through the driven wheel 43 and the synchronous belt. The driving gear 42 at the end of the shaft 41 engages with the gear ring 34, and then drives the rotating sleeve 33 and the gear ring 34 to rotate. When the gear ring 34 rotates, it can drive the cleaning scraper 35 on the inner wall to rotate along the outer wall of the filter sleeve 13, so that the mesh on the filter sleeve 13 is cleaned by the bristles 36 on the side of the cleaning scraper 35. The bristles 36 are made of hard material, so that mesh blockages can be efficiently cleaned.

[0039] Reference Figure 4-6As shown, two groups of flushing components distributed in a circular array are provided on the side of the fixed ring 32. The flushing components include a support plate 55 provided on the inner side of the housing 11. A plurality of flushing nozzles 56 distributed in a linear array are provided on the side of the support plate 55. A linkage structure corresponding to the support plate 55 is provided on the side of the fixed ring 32.

[0040] The linkage structure includes a guide groove 51 formed on the side of the fixed ring 32. A guide block 52 is slidably mounted on the inner wall of the guide groove 51. A guide ring groove 53 is formed on the inner wall of the housing 11 at the end away from the drive motor 14. A slider 54 is slidably mounted on the inner wall of the guide ring groove 53. The two ends of the support plate 55 are respectively fixedly connected to the guide block 52 and the slider 54. The outer walls of the two sliders 54 are provided with torsion springs 57, and the two ends of the torsion springs 57 are respectively fixedly connected to the housing 11 and the slider 54. A toggle structure corresponding to the rotating sleeve 33 is provided between the guide block 52 and the guide groove 51.

[0041] The toggle structure includes a guide opening 61 opened on the side of the guide block 52, and a stop block 62 is slidably installed on the inner wall of the guide opening 61. A spring 63 is installed at the end of the stop block 62, and the two ends of the spring 63 are respectively fixedly connected to the guide opening 61 and the stop block 62. A clearance opening 65 corresponding to the stop block 62 is opened on the inner wall of the end of the guide groove 51. Two driving blocks 64 distributed in a ring array are fixedly installed on the outer wall of the rotating sleeve 33, and corresponding inclined surfaces are provided on the ends of the driving block 64 and the stop block 62.

[0042] When the driving block 64 rotates with the rotating sleeve 33, the outer wall of the rotating sleeve 33 is fixed with two driving blocks 64 distributed in an annular array. Therefore, when the driving block 64 rotates with the rotating sleeve 33, it can be moved by toggling the stop block 62. Under the action of the torsion spring 57, the guide block 52 is initially located at the end of the guide groove 51 away from the clearance opening 65. At this time, under the action of the spring 1 63, the stop block 62 can protrude from the guide opening 61, and when the driving block 64 contacts the stop block 62, the end of the stop block 62 is abutted against the inner wall of the guide groove 51 and cannot slide into the guide opening 61. Therefore, when the driving block 64 rotates with the rotating sleeve 33, it can drive the stop block 62, so that the stop block 62 drives the guide block 52 to slide along the guide groove 51, and then drives the support plate 55 and the flushing nozzle 56 to rotate. When the stop block 62 moves to the position of the clearance opening 65, the driving block 64 can move the stop block 62 by the inclined surface The pressure is applied, so that the block 62 slides along the guide port 61 to the clearance port 65, making way for the driving block 64, and the driving block 64 can pass through the block 62. When the driving block 64 passes the position of the block 62, the block 62 can move back and forth and reset under the action of the spring 1 63. Under the action of the torsion spring 57, the guide block 52 can move back and forth and reset, thereby realizing the reciprocating rotation of the support plate 55 and the flushing nozzle 56. The flushing nozzle 56 is supplied with water through a hose, and the hose is fixed on the support plate 55, so it will not affect the movement of the support plate 55 and the flushing nozzle 56. This connection method is an existing mature technology and will not be described in detail here. The flushing nozzle 56 needs to be turned on when the device is not performing sludge treatment. The flushing nozzle 56, combined with the reciprocating rotation, can perform high-pressure flushing on the outer wall of the filter sleeve 13, ensuring the cleanliness of the filter sleeve 13 and the cleaning of the mesh, reducing blockage, and making the cleaning of the filter sleeve 13 more convenient.

[0043] Reference Figure 8 and Figure 9 As shown, the inner wall of the casing 11 at one end of the discharging structure 15 is provided with a vibration assembly corresponding to the filter sleeve 13, and the vibration assembly includes a fixed sleeve 71 fixedly mounted on the inner wall of the casing 11 away from the drive motor 14, and a sliding ring 72 is slidably mounted on the inner wall of the fixed sleeve 71. A plurality of springs 73 distributed in an annular array are fixedly mounted between the sliding ring 72 and the inner wall of the fixed sleeve 71, and the end of the filter sleeve 13 is fixedly connected to the side of the sliding ring 72. A through opening 74 is opened on the outer wall of the fixed sleeve 71, and a support rod 75 is fixedly mounted on the outer wall of the sliding ring 72. The end of the support rod 75 passes through the through opening 74 and is fixedly mounted with a shift block 76. The cross-sectional shape of the shift block 76 is an isosceles trapezoid, and the end of the support plate 55 is fixedly mounted with a shift rod 77 corresponding to the shift block 76.

[0044] When the support plate 55 rotates back and forth in the guide ring groove 53 through the slider 54, the lever 77 at the end of the support plate 55 can contact the lever block 76, and when in contact, the lever 77 can drive the lever block 76, the support rod 75 and the sliding ring 72 to slide along the fixed sleeve 71 under the action of the inclined surface on the lever block 76, and drive the filter sleeve 13 to slide, compressing the spring 2 73. When the lever 77 is separated from the lever block 76, the lever block 76 is released from the limit, and the sliding ring 72 can be pushed to slide in the opposite direction under the action of the spring 2 73, thereby driving the filter sleeve 13 to vibrate, so that impurities on the outer wall of the filter sleeve 13 can be vibrated off, and the use of the flushing nozzle 56 and the cleaning scraper 35 at different stages can jointly ensure the filtering effect of the filter sleeve 13, making the sludge treatment more efficient.

[0045] Working principle: When in use, the casing 11 can be erected first so that the sewage collection box and the sludge collection box are respectively located directly below the liquid outlet pipe 22 and the discharge structure 15. The casing 11 connects the feeding pipe 21 with the sludge feeding pipe. The sludge can enter the support sleeve 31 through the feeding pipe and the feeding pipe 21 and contact the spiral extrusion roller 12. When the drive motor 14 is turned on, the spiral extrusion roller 12 can be driven to rotate. When the spiral extrusion roller 12 rotates, the sludge can be transported. In the process of transportation, the closer the spiral extrusion roller 12 is to the direction of the discharge structure 15, the closer the distance between its blades is. Therefore, the sludge can be squeezed during the transportation process. When the sludge is squeezed, the sewage inside it can pass through the filter sleeve 13 and be discharged to the inner side of the casing 11, and can be discharged to the sewage collection box along the liquid outlet pipe 22. The sludge after dehydration can enter the sludge collection box through the discharge structure 15.

[0046] When the driving motor 14 drives the spiral extrusion roller 12 to rotate, it can drive the shaft 41 to rotate through the driven wheel 43 and the synchronous belt. The driving gear 42 at the end of the shaft 41 is engaged with the gear ring 34, thereby driving the rotating sleeve 33 and the gear ring 34 to rotate. When the gear ring 34 rotates, it can drive the cleaning scraper 35 on the inner wall to rotate along the outer wall of the filter sleeve 13. The other end of the cleaning scraper 35 overlaps the outer wall of the fixed sleeve 71, so that the cleaning scraper 35 can rotate stably, thereby cleaning the mesh on the filter sleeve 13 through the bristles 36 on the side of the cleaning scraper 35. The bristles 36 are made of hard material, so that mesh blockages can be efficiently cleaned.

[0047] When the driving block 64 rotates with the rotating sleeve 33, the outer wall of the rotating sleeve 33 is fixed with two driving blocks 64 distributed in an annular array. Therefore, when the driving block 64 rotates with the rotating sleeve 33, it can be moved by toggling the stop block 62. Under the action of the torsion spring 57, the guide block 52 is initially located at the end of the guide groove 51 away from the clearance opening 65. At this time, under the action of the spring 1 63, the stop block 62 can protrude from the guide opening 61, and when the driving block 64 contacts the stop block 62, the end of the stop block 62 is abutted against the inner wall of the guide groove 51 and cannot slide into the guide opening 61. Therefore, when the driving block 64 rotates with the rotating sleeve 33, it can drive the stop block 62, so that the stop block 62 drives the guide block 52 to slide along the guide groove 51, and then drives the support plate 55 and the flushing nozzle 56 to rotate. When the stop block 62 moves to the position of the clearance opening 65, the driving block 64 can move the stop block 62 by the inclined surface The pressure is applied, so that the block 62 slides along the guide opening 61 to the clearance opening 65, making way for the driving block 64, and the driving block 64 can pass through the block 62. When the driving block 64 passes the position of the block 62, the block 62 can be moved back and reset under the action of the spring 1 63. Under the action of the torsion spring 57, the guide block 52 can be moved back and reset, thereby realizing the reciprocating rotation of the support plate 55 and the flushing nozzle 56. The flushing nozzle 56 is supplied with water through a hose, and the hose is fixed on the support plate 55, so it will not affect the movement of the support plate 55 and the flushing nozzle 56. This connection method is an existing mature technology and will not be described in detail here. The flushing nozzle 56 needs to be turned on when the device is not processing sludge. The flushing nozzle 56, combined with the reciprocating rotation, can perform high-pressure flushing on the outer wall of the filter sleeve 13, ensuring the cleanliness of the filter sleeve 13 and the cleaning of the mesh, reducing blockage, and making the cleaning of the filter sleeve 13 more convenient;

[0048] The cam 72 is pressed against the filter housing 71 and the filter housing 72 is pressed against the filter housing 71 to release the filter housing 71. The filter housing 72 is pressed against the filter housing 71 to release the filter housing 71.

[0049] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
