Description
Technical Field
[0001] This invention relates to the field of water conservancy engineering technology, and in particular to a water conservancy engineering sediment treatment device and its usage method. Background Technology
[0002] During the construction of water conservancy projects, sediment accumulation is frequently encountered. Excessive sediment accumulation can severely impact further water conservancy construction, thus necessitating sediment treatment. Chinese Patent No. CN209974557U discloses a sediment treatment device for water conservancy projects, comprising a base frame, a partition plate fixedly connected to the middle of the base frame, vertical rods fixedly connected to the upper ends of the partition plate, and round rods hinged to the other ends of the vertical rods. Symmetrically, the round rods are fixedly connected to one side of a separation tank. A feed pipe is fixedly connected to the middle of the separation tank, a disc is fixedly connected inside the separation tank, and a discharge pipe is fixedly connected to the bottom of the separation tank.
[0003] Existing sediment treatment devices are unable to effectively crush sediment, leading to blockages caused by larger gravels. Furthermore, their filtration efficiency is low, as sediment easily clogs the filter screen, affecting the filtration effect. Additionally, existing sediment treatment devices require a rotating agitator, typically positioned in the center of the device to ensure uniform mixing. This results in the feed inlet being located in an eccentric area, causing the feed material to fall directly to the bottom and then be crushed and filtered by the agitator and crushing disc. Consequently, the mixing and crushing are uneven, reducing efficiency.
[0004] Therefore, we propose a sediment treatment device for water conservancy projects and its application method to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing sediment treatment devices, such as the inability to effectively crush sediment, the blockage of the device caused by large sand particles, low filtration efficiency, and the tendency of sediment to clog the filter screen and affect the filtration effect. Therefore, this invention proposes a sediment treatment device for water conservancy projects and its usage method.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A sediment treatment device for water conservancy projects includes a base, a support plate fixedly installed on one side of the top of the base, a crushing box fixedly installed on the top of the support plate, a feed hopper connected to one side of the top of the crushing box, an electrically controlled door at the bottom outlet of the feed hopper, a frame fixedly installed at the bottom of the crushing box, a motor fixedly installed at the bottom of the frame, a worm gear fixedly installed on the output shaft of the motor, a first shaft fixedly installed at one end of the worm gear, and a plurality of first crushing discs fixedly installed on the outside of the first shaft, the plurality of first crushing discs being equally spaced, and a plurality of first through holes being formed on the first crushing discs. The top of the crushing box has two mounting holes, each containing a second shaft that is rotatably mounted. Multiple second crushing discs are fixedly mounted on the outer sides of each second shaft, with equal intervals between them. Each second crushing disc has multiple second through holes. The highest second crushing disc on the second shaft near the feed hopper is inclined, and the through holes in a portion of the fan-shaped area of this inclined disc are blind holes. The opening and closing frequency of the electrically controlled door is matched to the rotational speed of the second shaft, ensuring that the amount of mud and sand falling into the blind holes and through holes is equal per unit time. The tops of both second shafts are fixed. A first pulley is installed, and a second pulley is fixedly installed at the top of the first shaft. The second pulley and the two first pulleys are connected by the same belt. A common horizontal shaft is rotatably installed on the inner walls of both sides of the frame. A worm gear is fixedly installed on the horizontal shaft, and the worm gear meshes with a worm. Turntables are fixedly installed at both ends of the horizontal shaft. Round rods are fixedly installed at the bottom of the two turntables on their opposite sides. The top of the base has multiple vertical holes, and support rods are slidably installed in each of the multiple vertical holes. A filter box is fixedly installed at the top of the multiple support rods. A filter screen is fixedly installed inside the filter box. A drain is connected to one bottom side of the filter box. The filter box has a connecting pipe at the bottom, with one end extending into the filter box. The top of the filter box is hinged to two connecting rods, the other ends of which are fixedly fitted with sleeves. The two sleeves are respectively rotatably fitted onto the outside of the corresponding round rods. The top of the filter box has a through hole, in which a sliding plate is slidably installed. A roller is rotatably installed on the top rear side of the sliding plate. A triangular plate is fixedly installed at the bottom of the frame, and the roller is rotatably connected to the bottom of the triangular plate. A horizontal plate is fixedly installed at the bottom of the sliding plate, and multiple scrapers are fixedly installed at the bottom of the horizontal plate. The multiple scrapers are movably abutting against the top of the filter screen.
[0008] Preferably, a connecting spring is fixedly connected to one side of the skateboard, and one end of the connecting spring is fixedly connected to the inner wall of the through hole to reset the skateboard.
[0009] Preferably, the same limiting rod is fixedly connected to the inner walls on both sides of the through hole, and the slide plate is slidably sleeved on the outside of the limiting rod to guide the slide plate to move laterally.
[0010] Preferably, a sealing ring is fixedly sleeved on the outer side of the first shaft, and the sealing ring is in movable sealing contact with the bottom of the crushing box to seal the crushing box.
[0011] Preferably, a fixing plate is fixedly installed on the other side of the filter box, and a vertical plate is fixedly installed on one side of the fixing plate. Multiple grooves are opened on one side of the vertical plate, and ball bearings are movably connected in each of the multiple grooves. The multiple ball bearings are rotatably connected to one side of the support plate to guide the filter box.
[0012] Preferably, the top of the base is fixedly connected to multiple compression springs, one end of each compression spring being fixedly connected to the bottom of the filter box to provide auxiliary support for the filter box.
[0013] Preferably, a cleaning port is provided on one side of the filter box, and a baffle is movably connected inside the cleaning port. The baffle is fixedly connected to one side of the filter box by bolts, which facilitates the cleaning of the filtered mud and sand.
[0014] The present invention also provides a method for using a sediment treatment device for water conservancy projects, comprising the following steps:
[0015] S1: The mud and sand are fed into the crushing box through the feed hopper. The motor is turned on, and the motor output shaft drives the worm gear to rotate. The worm gear drives the first shaft to rotate, and the first shaft drives the first crushing disc to rotate. The first crushing disc crushes large pieces of mud and sand and gravel by rotating. At the same time, the rotation of the first shaft drives the second pulley to rotate. The second pulley drives the two first pulleys to rotate at high speed through the belt. The two first pulleys drive the corresponding second shafts to rotate, and the second shaft drives the second crushing disc to rotate, thereby improving the crushing effect of mud and sand and preventing blockage of the equipment. During the process of mud and sand entering the crushing box from the feed hopper, it falls in stages into the through hole area and blind hole area of the top second crushing disc, so that some of it slides into the first crushing disc at an angle, and some falls from the through hole into the bottom second crushing disc, thereby diverting the mud and sand entering from the eccentric feed hopper and ensuring uniform mixing.
[0016] S2: The sludge and sand crushed in the crushing box enter the filter box through the connecting pipe. The filter screen filters the sludge and sand, and the filtered water is discharged through the drain pipe. The worm gear rotates at the same time, causing the worm wheel to rotate. The worm wheel drives the horizontal shaft to rotate, and the horizontal shaft drives two turntables. The two turntables drive two round rods to make circular motion around the axis of the horizontal shaft. The two round rods drive the filter box to move up and down reciprocally through the corresponding sleeves and connecting rods, thereby causing the filter screen and sludge inside to vibrate up and down, improving the filtration efficiency of the filter screen and preventing the sludge and sand from clogging the filter holes, thus ensuring the filtration effect.
[0017] S3: While the filter box moves up and down, the limit rod drives the slide plate to move up and down. During the upward movement of the slide plate, the connection between the bottom of the triangular plate and the roller drives the slide plate to move to one side and compresses the connecting spring. When the slide plate moves downward, the slide plate returns to its original position and slides in the opposite direction under the elastic force of the connecting spring. Thus, the slide plate moves left and right. The slide plate drives multiple scrapers to move left and right through the horizontal plate, thereby pushing the mud and sand to one side, further preventing the filter screen from clogging and facilitating the cleaning of the filtered mud and sand.
[0018] Compared with the prior art, the present invention provides a sediment treatment device for water conservancy projects and its usage method, which has the following beneficial effects:
[0019] (1) By driving the three crushing shafts to rotate simultaneously, the crushing effect of mud and sand is improved, preventing large pieces of mud and sand from clogging the equipment.
[0020] (2) By driving the filter box to move up and down repeatedly, the filter screen and sediment inside it will vibrate up and down repeatedly, thereby improving the filtration efficiency of the filter screen and preventing the sediment from clogging the filter holes, thus ensuring the filtration effect.
[0021] (3) By driving multiple scrapers to move back and forth, the mud and sand are pushed to one side, which further prevents the filter screen from clogging and makes it easier to clean the filtered mud and sand.
[0022] (4) The tilted crushing disc with differentiated through-hole structure and the eccentric design of the feed hopper in this invention enable the falling mud and sand to be evenly distributed, so that the mud and sand will not accumulate eccentrically, and the uniformity of stirring and crushing is enhanced.
[0023] This invention is reasonably designed. By driving the three crushing shafts to rotate, it improves the crushing effect on mud and sand, preventing large pieces of mud and sand from clogging the equipment. By driving the filter box and filter screen to vibrate up and down with the mud and sand, it also drives multiple scrapers to move left and right, improving the filtration efficiency of the filter screen and preventing the mud and sand from clogging the filter holes, thus ensuring the filtration effect.

[0040] This embodiment also provides a method for using a sediment treatment device for water conservancy projects, including the following steps:
[0041] S1: The mud and sand are fed into the crushing box 3 through the feed hopper 9. The motor 11 is turned on. The output shaft of the motor 11 drives the worm gear 12 to rotate. The worm gear 12 drives the first shaft 13 to rotate. The first shaft 13 drives the first crushing disc 14 to rotate. The first crushing disc 14 crushes large mud and sand pieces and gravel by rotating. At the same time, the rotation of the first shaft 13 drives the second pulley 18 to rotate. The second pulley 18 drives the two first pulleys 17 to rotate at high speed through the belt 19. The two first pulleys 17 drive the corresponding second shafts 15 to rotate. The second shafts 15 drive the second crushing disc 16 to rotate, thereby improving the crushing effect of the mud and sand and preventing blockage of the equipment. During the process of the mud and sand entering the crushing box 3 from the feed hopper 9, it falls into the through hole area and blind hole area of the top second crushing disc 16 in stages. Some of it slides into the first crushing disc 14 at an angle, and some falls from the through hole into the bottom second crushing disc 16. This diverts the mud and sand entering from the eccentric feed hopper 9 and ensures that it is mixed evenly.
[0042] S2: The sludge and sand crushed by the crushing box 3 enter the filter box 5 through the connecting pipe 30. The filter screen 6 filters the sludge and sand, and the filtered water is discharged through the drain pipe 7. The worm gear 12 rotates at the same time, causing the worm wheel 21 to rotate. The worm wheel 21 drives the horizontal shaft 20 to rotate. The horizontal shaft 20 drives two turntables 22. The two turntables 22 drive two round rods 23 to make circular motion based on the axis of the horizontal shaft 20. The two round rods 23 drive the filter box 5 to move up and down reciprocally through the corresponding sleeves 25 and connecting rods 24, thereby causing the filter screen 6 and the sludge and sand inside to vibrate up and down, improving the filtration efficiency of the filter screen 6 and preventing the sludge and sand from clogging the filter holes, thus ensuring the filtration effect.
[0043] S3: While the filter box 5 moves up and down, the limit rod 34 drives the slide plate 31 to move up and down. During the upward movement of the slide plate 31, the connection between the bottom of the triangular plate 33 and the roller 32 drives the slide plate 31 to move to one side and compresses the connecting spring 35. When the slide plate 31 moves downward, the slide plate 31 resets and slides in the opposite direction under the elastic force of the connecting spring 35. Thus, the slide plate 31 moves left and right. The slide plate 31 drives multiple scrapers 28 to move left and right through the horizontal plate 27, thereby pushing the mud and sand to one side, further preventing the filter screen 6 from clogging, and facilitating the cleaning of the filtered mud and sand.
[0044] The working principle of this invention is as follows: Sand and mud are fed into the crushing chamber 3 through the feed hopper 9. The motor 11 is turned on, and its output shaft drives the worm gear 12 to rotate. The worm gear 12 drives the first shaft 13 to rotate, which in turn drives the first crushing disc 14 to rotate. The first crushing disc 14 crushes large pieces of sand and gravel through rotation. Simultaneously, the rotation of the first shaft 13 drives the second pulley 18 to rotate. The second pulley 18, via a belt 19, drives two first pulleys 17 to rotate at high speed. Each of the two first pulleys 17 drives its corresponding second shaft 15 to rotate, which in turn drives the second crushing disc 16 to rotate, thereby improving the crushing effect on the sand and mud and preventing blockage of the equipment. The sand and mud crushed in the crushing chamber 3 enter the filter chamber 5 through the connecting pipe 30. The filter screen 6 filters the sand and mud, and the filtered water is discharged through the drain pipe 7. Simultaneously, the rotation of the worm gear 12 causes the worm wheel 21 to rotate, which in turn drives the horizontal shaft 20 to rotate. The horizontal shaft 20 then drives two turntables 22. Two turntables 22 drive two round rods 23 to perform circular motion around the axis of the horizontal axis 20. The two round rods 23 drive the filter box 5 to move up and down reciprocally through the corresponding sleeves 25 and connecting rods 24, thereby causing the filter screen 6 and the sediment inside to vibrate up and down, improving the filtration efficiency of the filter screen 6 and preventing the sediment from clogging the filter holes, thus ensuring the filtration effect. While the filter box 5 moves up and down reciprocally, it drives the slide plate 31 to move up and down reciprocally through the limit rod 34. During the upward movement of the slide plate 31, the connection between the bottom of the triangular plate 33 and the roller 32 drives the slide plate 31 to move to one side and compress the connecting spring 35. When the slide plate 31 moves downward, it resets and slides in the opposite direction under the elastic force of the connecting spring 35, thereby causing the slide plate 31 to move left and right reciprocally. The slide plate 31 drives multiple scrapers 28 to move left and right reciprocally through the horizontal plate 27, thereby pushing the sediment to one side, further preventing the filter screen 6 from clogging and facilitating the cleaning of the filtered sediment.
[0045] To further improve the uniformity, the multiple second crushing discs 16 on the second shaft 15 near the feed hopper 9 can be tilted, and the through holes in some fan-shaped areas of the tilted discs can be blind holes. Then, the blind hole areas on adjacent second crushing discs 16 can be staggered.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

The baffle (8) is fixedly connected to one side of the filter box (5) by bolts.
8. A method of using a sediment treatment device for water conservancy projects, characterized in that, Includes the following steps: S1: Put the mud and sand into the crushing box (3) through the feed hopper (9), turn on the motor (11), the output shaft of the motor (11) drives the worm (12) to rotate, the worm (12) drives the first shaft (13) to rotate, the first shaft (13) drives the first crushing disc (14) to rotate, the first crushing disc (14) crushes large mud and sand blocks and gravel by rotating, the first shaft (13) drives the second pulley (18) to rotate at the same time, the second pulley (18) drives the two first pulleys (17) to rotate at high speed through the belt (19), the two first pulleys (17) respectively The corresponding second shaft (15) is driven to rotate, and the second shaft (15) drives the second crushing disc (16) to rotate, thereby improving the crushing effect of mud and sand and preventing blockage of the equipment. During the process of mud and sand entering the crushing box (3) from the feed hopper (9), it falls into the through hole area and blind hole area of the top second crushing disc (16) in stages, thereby partially tilting and sliding into the first crushing disc (14), and partially falling from the through hole into the bottom second crushing disc (16), thereby diverting the mud and sand entering from the eccentric feed hopper (9) to ensure uniform mixing. S2: The silt and sand crushed by the crushing box (3) enter the filter box (5) through the connecting pipe (30). The filter screen (6) filters the silt and sand and discharges the filtered water through the drain pipe (7). The worm gear (12) rotates while driving the worm wheel (21) to rotate. The worm wheel (21) drives the horizontal shaft (20) to rotate. The horizontal shaft (20) drives the two turntables (22). The two turntables (22) drive the two round rods (23) to make circular motion based on the axis of the horizontal shaft (20). The two round rods (23) drive the filter box (5) to move up and down through the corresponding sleeve (25) and connecting rod (24), thereby driving the filter screen (6) and silt inside to vibrate up and down, improving the filtration efficiency of the filter screen (6), and preventing the silt from clogging the filter holes, thus ensuring the filtration effect. S3: While the filter box (5) moves up and down, the limit rod (34) drives the slide plate (31) to move up and down. When the slide plate (31) moves upward, the connection between the bottom of the triangular plate (33) and the roller (32) drives the slide plate (31) to move to one side and compresses the connecting spring (35). When the slide plate (31) moves downward, the slide plate (31) resets and slides in the opposite direction under the elastic force of the connecting spring (35), so that the slide plate (31) moves left and right. The slide plate (31) drives multiple scrapers (28) to move left and right through the horizontal plate (27), thereby pushing the mud and sand to one side, further preventing the filter screen (6) from clogging, and making it easier to clean the filtered mud and sand.
