[0003] When the existing sludge dewatering device treats sludge, the sludge in the river channel contains hard impurities such as stones, metal fragments, glass, etc. These hard impurities will damage the filter belt, pressure roller or other key components during the pressure filtration process, affecting the normal operation of the equipment. When screening through a drum sieve, the sludge will adhere to the inner wall of the drum sieve, and at the same time, the hard impurities are easily stuck in the sieve holes of the drum sieve, causing the blockage of the sieve holes and affecting the normal screening of the drum sieve. Summary of the Invention
[0004] The problem solved by the present invention is to provide a sludge dewatering device for ecological treatment of water conservancy river channels, which solves the technical problems that when the existing sludge dewatering device treats sludge, the sludge in the river channel contains hard impurities such as stones, metal fragments, glass, etc. These hard impurities will damage the filter belt, pressure roller or other key components during the pressure filtration process, affecting the normal operation of the equipment. When screening through a drum sieve, the sludge will adhere to the inner wall of the drum sieve, and at the same time, the hard impurities are easily stuck in the sieve holes of the drum sieve, causing the blockage of the sieve holes and affecting the normal screening of the drum sieve.
[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A sludge dewatering device for ecological treatment of water conservancy river channels includes a belt filter press and an impurity removal mechanism. The impurity removal mechanism is installed on the belt filter press. The impurity removal mechanism includes a mounting frame inclinedly installed on the frame of the belt filter press. A drum sieve is rotatably installed inside the mounting frame. A spiral blade is arranged inside the drum sieve, and the drum sieve is inclined. One end of the mounting frame is installed with a feed hopper, and the bottom end of the feed hopper is located inside the top end of the drum sieve. The other end of the mounting frame is installed with a waste discharge hopper, and the waste discharge hopper is located below the bottom end of the drum sieve. A transmission box is installed on the mounting frame. A multi-sided shaft is rotatably installed on the transmission box. A sliding shaft is slidably sleeved on the multi-sided shaft. A number of arc-shaped rubber rods are installed on the sliding shaft, and the rubber rods are circumferentially and equally angularly distributed along the axial direction of the sliding shaft.
[0006] Preferably, a number of wheel plates are installed on the mounting frame, and support wheels are installed on the wheel plates. Wheel grooves are opened on the outer sides of both ends of the drum sieve, and the support wheels are rotatably located in the wheel grooves.
[0007] Preferably, a motor is installed on the transmission case. The output end of the motor is provided with a rotating shaft installed inside the transmission case, and the rotating shaft is connected to the polygonal shaft. A worm gear is installed outside the rotating shaft.
[0008] Preferably, rotating teeth are installed on the polygonal shaft. External teeth are arranged on the outer side of the bottom end of the drum screen, and the external teeth are meshed with the rotating teeth.
[0009] Preferably, a worm is installed inside the transmission case, and the worm is meshed with the worm gear.
[0010] Preferably, transmission shafts are installed at both ends of the worm. Cam wheels are installed at the ends of the transmission shafts outside the transmission case.
[0011] Preferably, guide rails are arranged on the bottom side of the top of the mounting frame. A sliding plate is slidably installed on the guide rails. Bearing seats are installed on the bottom sides of both ends of the sliding plate, and the bearing seats are rotatably connected to the sliding shafts.
[0012] Preferably, a baffle is installed at the end of the sliding plate. Wheel seats are installed at both ends of the baffle, and guide wheels are installed on the wheel seats, and the guide wheels roll along the cam wheels.
[0013] Preferably, support plates are symmetrically installed on the bottom side of the top of the mounting frame. Springs are installed between the two support plates and both ends of the baffle.
[0014] Preferably, the specific operation steps of this sludge dewatering device are as follows: Step 1: Pump out and transfer the sludge in the water conservancy river channel, and convey the sludge to the feed hopper of the impurity removal mechanism. The sludge enters the drum screen through the feed hopper. At this time, the motor works to drive the rotating shaft to rotate, realizing the rotation of the polygonal shaft and the rotating teeth. The rotating rotating teeth cooperate with the meshed external teeth to drive the drum screen to rotate on the support wheels. As the drum screen rotates, the spiral blades drive the sludge to roll in the drum screen, and the sludge falls onto the filter belt of the belt filter press through the sieve slots of the drum screen. Through the transmission of the filter belt, water is removed by pressing in the belt filter press, removing the water in the sludge. The sludge cake obtained by pressing can be used as land fertilizer. The residual impurities in the drum screen are discharged through the waste discharge hopper; Step 2: The polygonal shaft drives the sliding shaft to rotate, and the rubber rods on the sliding shaft rotate synchronously. The surface of the rotating drum screen is knocked by the rubber rods. At the same time, when the worm gear rotates, it drives the meshed worm to rotate. The worm drives the cam wheel to rotate through the transmission shaft. Under the action of the spring, the guide wheels on the wheel seats always rotate along the cam wheels. As the cam wheels rotate, the sliding plate reciprocates horizontally along the guide rails. At this time, the bearing seats drive the sliding shafts and the rubber rods to move reciprocally. The surface of the rotating drum screen is continuously knocked by the rotating and translating rubber rods, vibrating off the sludge adhering to the inner wall of the drum screen and the impurities stuck in the sieve slots of the drum screen, preventing the drum screen from being blocked.
[0015] The beneficial effects of the present invention are as follows: By the operation of the motor, the common rotation of the drum sieve, the sliding shaft and the cam is realized. Through the rotation of the drum sieve, the screening of sludge is achieved, and foreign matters existing in the sludge are removed, avoiding damage to the filter belt, pressure rollers or other key components during the sludge dewatering by the belt filter press. The rotation of the sliding shaft realizes the synchronous rotation of the rubber rods. The rotating rubber rods strike the surface of the rotating drum sieve. The rotation of the cam realizes the reciprocating translation of the sliding plate. The bearing seat drives the sliding shaft and the rubber rods to move reciprocally. The rotating and translating rubber rods continuously strike the surface of the rotating drum sieve, ensuring that the struck parts of the drum sieve are completely free of dead angles, shaking off the sludge adhering to the inner wall of the drum sieve and the sundries stuck in the sieve slots of the drum sieve, avoiding the blockage of the drum sieve and the inability to use it normally due to the adhesion of sludge.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0019] The following gives specific embodiments.
[0020] See Figures 1 to 5, A sludge dewatering device for ecological treatment of water conservancy river channels, comprising a belt filter press 1 and an impurity removal mechanism 2. The impurity removal mechanism 2 is installed on the belt filter press 1. The impurity removal mechanism 2 includes a mounting frame 3 obliquely installed on the frame of the belt filter press 1. A drum screen 4 is rotatably installed in the mounting frame 3. A spiral blade 5 is arranged inside the drum screen 4, and the drum screen 4 is obliquely arranged. One end of the mounting frame 3 is installed with a feed hopper 6, and the bottom end of the feed hopper 6 is located inside the top end of the drum screen 4. The other end of the mounting frame 3 is installed with a waste discharge hopper 7, and the waste discharge hopper 7 is located below the bottom end of the drum screen 4. A transmission box 8 is installed on the mounting frame 3. A multi-sided shaft 9 is rotatably installed on the transmission box 8. A sliding shaft 10 is slidably sleeved on the multi-sided shaft 9. A number of arc-shaped rubber rods 11 are installed on the sliding shaft 10, and the rubber rods 11 are circumferentially and equiangularly distributed along the axial direction of the sliding shaft 10.
[0021] A number of wheel plates are installed on the mounting frame 3, and a support wheel 12 is installed on the wheel plates. Wheel grooves are opened on the outer sides of both ends of the drum screen 4, and the support wheel 12 rotates in the wheel grooves, playing a role in supporting and guiding the rotating drum screen 4. A motor 13 is installed on the transmission box 8. A rotating shaft 14 is installed at the output end of the motor 13 inside the transmission box 8, and the rotating shaft 14 is connected to the multi-sided shaft 9. A worm gear 15 is installed on the outer side of the rotating shaft 14. A rotating gear 16 is installed on the multi-sided shaft 9. An external gear 17 is arranged on the outer side of the bottom end of the drum screen 4, and the external gear 17 meshes with the rotating gear 16. When the motor 13 works, the rotation of the rotating shaft 14 and the multi-sided shaft 9 is realized. The rotation of the multi-sided shaft 9 realizes the rotation of the rotating gear 16. The rotating rotating gear 16 cooperates with the meshing external gear 17 to drive the drum screen 4 to rotate on the support wheel 12. As the drum screen 4 rotates, the spiral blade 5 drives the sludge to roll inside the drum screen 4, thereby separating the sludge from the residual impurities.
[0022] Inside the transmission case 8, a worm 18 is installed. The worm 18 meshes with a worm wheel 15. At both ends of the worm 18, transmission shafts 19 are installed. At the ends of the transmission shafts 19 located outside the transmission case 8, cams 20 are installed. On the bottom side of the top of the mounting frame 3, a guide rail 21 is provided. A sliding plate 22 is slidably installed on the guide rail 21. At the bottom sides of both ends of the sliding plate 22, bearing seats 23 are installed. The bearing seats 23 are rotatably connected to the sliding shafts 10. At the end of the sliding plate 22, a baffle 25 is installed. At both ends of the baffle 25, wheel seats 27 are installed. Guide wheels 28 are installed on the wheel seats 27, and the guide wheels 28 roll along the cam 20. On the bottom side of the top of the mounting frame 3, support plates 24 are symmetrically installed. Springs 26 are installed between the two support plates 24 and both ends of the baffle 25. When the sliding shaft 10 rotates, the rubber rod 11 rotates synchronously. The surface of the rotating drum screen 4 is struck by the rotating rubber rod 11. When the worm wheel 15 rotates, it drives the meshing worm 18 to rotate. The worm 18 drives the cam 20 to rotate through the transmission shaft 19. Under the action of the spring 26, the rotation of the cam 20 causes the reciprocating translation of the sliding plate 22. The bearing seat 23 drives the sliding shaft 10 and the rubber rod 11 to move reciprocally. The surface of the rotating drum screen 4 is continuously struck by the rotating and translating rubber rod 11, ensuring that the struck part of the drum screen 4 is fully covered without dead spots, shaking off the sludge adhering to the inner wall of the drum screen 4 and the sundries stuck in the sieve slots of the drum screen 4, and preventing the drum screen 4 from being blocked and unable to be used normally due to sludge adhesion.
[0023] Working principle: The sludge in the water conservancy river channel is pumped out and transferred, and the sludge is conveyed into the feed hopper 6 of the impurity removal mechanism 2. It enters the drum screen 4 through the feed hopper 6. At this time, the motor 13 works to drive the rotating shaft 14 to rotate, realizing the rotation of the multi-sided shaft 9 and the rotating teeth 16. The rotating rotating teeth 16 cooperate with the meshing external teeth 17 to drive the drum screen 4 to rotate on the support wheels 12. As the drum screen 4 rotates, the sludge is driven to roll in the drum screen 4 by the spiral blade 5 and falls onto the filter belt of the belt filter press 1 through the sieve slots of the drum screen 4. Through the transmission of the filter belt, water is removed by pressure filtration in the belt filter press 1, removing the moisture in the sludge. The cake obtained by pressure filtration can be used as land fertilizer. The residual sundries in the drum screen 4 are discharged through the waste discharge hopper 7. The multi-sided shaft 9 drives the sliding shaft 10 to rotate, and the rubber rod 11 on the sliding shaft 10 rotates synchronously. The surface of the rotating drum screen 4 is struck by the rubber rod 11. At the same time, when the worm wheel 15 rotates, it drives the meshing worm 18 to rotate. The worm 18 drives the cam 20 to rotate through the transmission shaft 19. Under the action of the spring 26, the guide wheel 28 on the wheel seat 27 always rotates along the cam 20. As the cam 20 rotates, the sliding plate 22 reciprocates along the guide rail 21. At this time, the bearing seat 23 drives the sliding shaft 10 and the rubber rod 11 to move reciprocally. The surface of the rotating drum screen 4 is continuously struck by the rotating and translating rubber rod 11, shaking off the sludge adhering to the inner wall of the drum screen 4 and the sundries stuck in the sieve slots of the drum screen 4, and preventing the drum screen 4 from being blocked; The common rotation of the drum screen 4, the sliding shaft 10, and the cam 20 is achieved by the operation of the motor 13. Through the rotation of the drum screen 4, the screening of the sludge is realized, and foreign matters existing in the sludge are removed, avoiding damage to the filter belt, the pressure roller, or other key components during the sludge dewatering by the belt filter press 1.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
