Description

Technical Field

[0001] This invention is a rapid dewatering device for sludge in civil construction, belonging to the field of civil construction. Background Technology

[0002] During civil construction, foundation pits need to be excavated. In this process, the excavated soil needs to be transported away by construction vehicles. The excavation of foundation pits often involves a large amount of silt with a high water content. During transportation, the construction vehicles will spill a lot of mud and water, which seriously affects road hygiene. Therefore, the silt needs to be dehydrated before transportation.

[0003] Existing sludge dewatering methods typically employ two conveyor belts, one above the other, with the gap between the belts gradually decreasing to compress and dewater the sludge. However, in practice, the conveyor belts often lack rigidity and are prone to deformation, resulting in insufficient pressure on the sludge. Furthermore, the conveyor belt mesh can become clogged with sludge, which cannot be completely removed by scrapers alone. This prevents the dewatered water from being effectively drained, causing it to be reabsorbed by the sludge, resulting in the final sludge still containing a significant amount of water and achieving poor dewatering efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a rapid dewatering device for sludge dewatering in civil engineering construction. To achieve this objective, the present invention employs the following technical solution:

A traction rod penetrating the moving plate is fixed between the L-shaped plate one and the L-shaped plate two. The other end of the lead screw is fitted with a bearing one fixed on the L-shaped plate two, and the screw motor is fixed on the moving plate.

[0007] Furthermore, the extrusion assembly includes an extrusion box fixed to the other end of the discharge pipe. The bottom of the extrusion box has an opening. The extrusion box is also fixed to the moving plate. There are two corresponding extrusion rollers inside the extrusion box. A motor plate is fixed to one side of the outer wall of the extrusion box. A forward and reverse motor is fixed to the motor plate. The output end of the forward and reverse motor is connected to a rotating rod. A gear is provided at the other end of the rotating rod. A meshing gear is engaged on one side of the gear.

[0008] Furthermore, the end of the extrusion roller is provided with a through rod that extends out of the extrusion box. The through end of the through rod and the outer surface of the rotating rod are both fitted with bearings II. The bearings II are respectively fixed to the outer wall of the extrusion box and the motor plate. The total number of bearings II is four.

[0009] Furthermore, round rods extending through the work box are fixedly provided on both sides of the bottom of the extrusion plate, and a bearing three fixed on the outer wall of the work box is sleeved on the other end of each round rod. Support legs are fixed between the four corners of the bottom of the worktable and the inner wall of the work box.

[0010] Furthermore, the pushing assembly includes an electric telescopic rod fixed to the back of the work box, and a push plate located inside the work box is fixedly provided on the output end of the electric telescopic rod. Both ends of the push plate are fixedly provided with thin rods that pass through the work box, and a baffle plate is fixedly provided on the protruding ends of the thin rods.

[0011] Furthermore, the front of the work box is provided with an opening slot that matches the baffle plate, and the bottom end of the push plate contacts the top surface of the worktable.

[0012] Furthermore, each of the filter components includes a double-layered filter frame inserted into the collection box and the working box. One end of each filter frame is fixedly provided with a mounting plate. A filter screen is arranged inside the filter frame. Several sets of cross-shaped secondary filter frames are also fixed between the filter frames. A secondary filter screen is arranged inside the secondary filter frame. A snap-in groove is provided at each corresponding corner of the double-layered filter frame. A locking groove is provided inside the snap-in groove.

[0013] Furthermore, a side baffle is provided in the slot, and a clamping plate matching the clamping slot is fixedly provided at the top and bottom of the side baffle.

[0015] The beneficial effects of this invention are:

[0016] The dewatering tank has a built-in feed inlet. The sludge enters the dewatering tank through the feed inlet. The screw motor is started to drive the screw rod to rotate, which in turn drives the screw blades to rotate, thus stirring and conveying the sludge in the dewatering tank. The bottom of the dewatering tank is designed with a collection box. Therefore, when stirring and conveying the sludge, the wastewater generated by the stirring and squeezing of the sludge is filtered through the filter components inside the collection box. The wastewater is finally collected at the bottom of the collection box, thus performing preliminary dewatering of the sludge.

[0017] After dewatering, the sludge enters the extrusion assembly through the discharge pipe. The extrusion assembly then compresses the dewatered sludge into sheet-like blocks. With the help of the moving assembly, the extruded sheet-like blocks are then evenly spread on the worktable. These evenly spread blocks are then extruded again by the extrusion plate, ensuring a more effective removal of water.

[0018] The water squeezed inside the working chamber is filtered through the filter assembly, thus the water is filtered and collected. The water can be collected later to clean some parts of the equipment. Finally, the pushing assembly squeezes out the sludge blocks from the working chamber. Attached Figure Description

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Please see Figure 1-7This invention provides a technical solution: a rapid dewatering device for civil engineering construction sludge, comprising a working box 1, an L-shaped plate 2 on one side of the outer wall of the working box 1, an L-shaped plate 3 on the other side of the outer wall of the working box 1, a moving assembly between the L-shaped plate 2 and the L-shaped plate 3, a dewatering box 4 on the moving assembly, an integrally formed collection box 5 fixedly mounted at the bottom of the dewatering box 4, a pressing assembly connected to one end of the dewatering box 4 via a discharge pipe 6, a pressing plate 7 rotatably connected to the center of the working box 1, a connecting assembly for connecting the pressing plate 7 on the back of the working box 1, a worktable 8 matching the pressing plate 7 fixedly mounted inside the working box 1, a pushing assembly corresponding to the worktable 8 on the back of the working box 1, a screw motor 24 mounted on the dewatering box 4, a screw rod located inside the dewatering box 4 at the output end of the screw motor 24, and threaded blades 25 fixedly mounted on the outer surface of the screw rod, and a screw rod 25 fixedly mounted on the outer surface of the screw rod, and a screw rod 25 fixedly mounted on the working box 1 and the collection box 5, respectively. Each dewatering tank 4 has a built-in feed inlet, through which sludge enters. The screw motor 24 is activated, driving the screw rod to rotate. The rotating screw rod, in turn, drives the threaded blades 25 to rotate, thus agitating and conveying the sludge within the dewatering tank 4. A collection box 5 is designed at the bottom of the dewatering tank 4. During the agitation and conveying of the sludge, the wastewater generated by the agitation and compression is filtered through the filter components inside the collection box 5. The wastewater is ultimately collected at the bottom of the collection box 5, performing preliminary dewatering of the sludge. The dewatered sludge then flows through the discharge pipe 6 into… Inside the extrusion assembly, the dewatered sludge is finally extruded into sheet-like blocks. Then, with the help of the moving assembly, the extruded sheet-like blocks are evenly spread on the worktable 8. The evenly spread blocks are then extruded again by the extrusion plate 7, which ensures a better effect of removing water. The water squeezed inside the work box 1 is filtered through the filter assembly, so the water is filtered and collected. The water can be collected later to clean some parts of the equipment. Finally, the pushing assembly pushes the extruded sludge blocks out of the work box 1.

[0030] See Figure 1The moving assembly includes a drive motor 9 fixed on the L-shaped plate 2. The output end of the drive motor 9 is provided with a lead screw 10. An L-shaped moving plate 11 is threaded onto the lead screw 10. The collection box 5 is fixed on the moving plate 11, and several reinforcing ribs 12 are fixed between the collection box 5 and the moving plate 11. A traction rod 13 is fixed between the L-shaped plate 2 and the L-shaped plate 3, passing through the moving plate 11. The other end of the lead screw 10 is fitted with a bearing 14 fixed on the L-shaped plate 3. The screw motor 24 is fixed on the moving plate 11. When the drive motor 9 is started, the lead screw 10 is rotated, and the moving plate 11 is moved. The drive motor 9 is a forward and reverse motor, so it moves the moving plate 11 left and right. This allows the squeezed sludge to be formed into blocks and evenly spread on the worktable 8. The designed bearing 14 ensures high rotational stability of the lead screw 10, and the traction rod 13 passes through the moving plate 11 to ensure that the moving plate 11 moves normally left and right on the lead screw, rather than causing the moving plate 11 to rotate on the lead screw.

[0031] See Figure 1-3 The extrusion assembly includes an extrusion box 15 fixed to the other end of the discharge pipe 6. The extrusion box 15 has an opening at the bottom and is also fixed to the moving plate 11. Inside the extrusion box 15 are two corresponding extrusion rollers 16. A motor plate 17 is fixed to one side of the outer wall of the extrusion box 15. A forward and reverse motor 18 is fixed to the motor plate 17. The output end of the forward and reverse motor 18 is connected to a rotating rod 19. A gear 20 is provided at the other end of the rotating rod 19. A meshing gear 21 meshes with one side of the gear 20. The extrusion rollers 16... The end of 6 is provided with a through rod 22 that passes through the extrusion box 15. The through end of the through rod 22 and the outer surface of the rotating rod 19 are both fitted with bearings 23. The bearings 23 are fixed on the outer wall of the extrusion box 15 and the motor plate 17 respectively. There are a total of four bearings 23. The design of the bearings 23 ensures better stability of the extrusion roller 16. The forward and reverse motor 18 drives the rotating rod 19 and the gear 20 to rotate in both directions, thus driving the meshing gear 21 to rotate as well. Therefore, it drives the corresponding extrusion roller 16 to move relative to each other, completing the final extrusion of sludge into blocks.

[0032] See Figure 1Both sides of the extrusion plate 7 are fixed with round rods 26 that protrude from the working box 1. The other end of each round rod 26 is fitted with a bearing 27 fixed on the outer wall of the working box 1. Support legs 28 are fixed between the four corners of the bottom of the worktable 8 and the inner wall of the working box 1. The round rods 26 that protrude from the working box 1 are fixed on both sides of the extrusion plate 7 and connected to the bearings 27 on the outer wall of the working box 1. This ensures that the extrusion plate 7 can rotate normally and can better cooperate with the connecting assembly for use. The connecting assembly drives the extrusion plate 7 to move and flip, thus completing the extrusion of sludge.

[0033] See Figure 1 and Figure 5 The pushing assembly includes an electric telescopic rod 29 fixed to the back of the work box 1. A push plate 30 located inside the work box 1 is fixedly provided on the output end of the electric telescopic rod 29. Thin rods 31 extending through the work box 1 are fixedly provided on both ends of the push plate 30. A baffle plate 32 is fixedly provided at the protruding ends of the thin rods 31. An opening slot 33 matching the baffle plate 32 is provided on the front of the work box 1. The bottom end of the push plate 30 is designed to contact the top surface of the worktable 8. The electric telescopic rod 29 drives the push plate 30 to move, and finally pushes away the blocky sludge on the worktable 8 and discharges it to the outside through the opening slot 33 for receiving.

[0034] See Figure 1 , 4-7, each of the filter components includes a double-layered filter frame 34 inserted into the collection box 5 and the working box 1. One end of each filter frame 34 is fixedly fitted with a mounting plate 35. A filter screen 36 is arranged inside each filter frame 34. Several sets of cross-shaped auxiliary filter frames 37 are also fixed between the filter frames 34. A secondary filter screen 38 is arranged inside each auxiliary filter frame 37. A snap-fit ​​groove 39 is provided at each corresponding corner of the double-layered filter frame 34. A clamping groove 40 is provided inside each snap-fit ​​groove 39. A side baffle 41 is fitted inside each snap-fit ​​groove 39. A clamping plate 42 matching the clamping groove 40 is fixedly provided at the top and bottom of each side baffle 41. Both the collection box 5 and the working box 1 are equipped with a drain pipe 43 with a control valve. The bottom of the water tank 4 is open, and an arc-shaped filter plate 44 is fitted inside the bottom of the dewatering tank 4. A secondary mounting plate 45 connected to the arc-shaped filter plate 44 is screwed through the movable plate 11. During the transportation of sludge in the dewatering tank 4, the sewage in the sludge is filtered through the arc-shaped filter plate 44 and then through the filter assembly on the collection tank 5. The water undergoes double-layer filtration through the filter screen 36, with multiple filtrations through the secondary filter screen 38 in between, thus ensuring better filtration effect. The arc-shaped filter plate 44 is easy to disassemble and install. The clamping plate 42 is clamped into the clamping groove 40, and the side baffle 41 can be installed to ensure better interception of impurities in the water and good impurity collection effect. The filter assembly can be manually disassembled later to remove the impurities intercepted by the filter assembly. The collected water can be used to rinse the parts of the equipment.

[0035] See Figure 5 The connecting component is an auxiliary electric telescopic rod 46 hinged to the back of the working box 1. The output end of the auxiliary electric telescopic rod 46 is hinged to the top surface of the extrusion plate 7. By activating the auxiliary electric telescopic rod 46, the extrusion plate 7 is driven to flip, and finally the extrusion plate 7 is made horizontal, pressing the sheet-like inner sludge and completing the removal of internal water.

[0036] During use, the dewatering tank 4 has a built-in feed inlet. The sludge enters the dewatering tank 4 through the feed inlet. The screw motor 24 is started to drive the screw rod to rotate. The rotation of the screw rod drives the threaded blades 25 to rotate, thus stirring and conveying the sludge in the dewatering tank 4. The bottom of the dewatering tank 4 is designed with a collection box 5. Therefore, when stirring and conveying the sludge, the wastewater generated by the stirring and squeezing of the sludge is filtered through the filter components inside the collection box 5. The wastewater is finally collected at the bottom of the collection box 5, thus performing preliminary dewatering of the sludge.

[0037] After dehydration, the sludge enters the extrusion assembly through the discharge pipe 6. The extrusion assembly then compresses the dehydrated sludge into sheet-like blocks. With the help of the moving assembly, the extruded sheet-like blocks are then moved and evenly spread on the worktable 8. The evenly spread blocks are then extruded again by the extrusion plate 7, which ensures a more effective removal of water.

[0038] The water squeezed inside the working chamber 1 is filtered through the filter assembly, thus the water is filtered and collected. The water can be collected later to clean some parts of the equipment. Finally, the pushing assembly squeezes the subsequent sludge blocks and pushes them out of the working chamber 1.

[0039] The drive motor 9 is started, which drives the lead screw 10 to rotate, ultimately moving the moving plate 11. The drive motor 9 is a forward and reverse motor, thus moving the moving plate 11 left and right. This ensures that the squeezed sludge is formed into blocks and evenly spread on the worktable 8. The designed bearing 14 ensures high rotational stability of the lead screw 10. The traction rod 13 passes through the moving plate 11 to ensure that the moving plate 11 moves normally left and right on the lead screw, rather than causing the moving plate 11 to rotate on the lead screw. The forward and reverse motor 18 drives the rotating rod 19 and gear 20 to rotate forward and reverse, thus driving the meshing gear 21 to rotate as well. This causes the corresponding squeezing roller 16 to move relative to the roller, completing the final squeezing of the sludge into blocks. The electric telescopic rod 29 drives the push plate 30 to move, ultimately pushing away the blocky sludge on the worktable 8 and discharging it to the outside through the opening groove 33 for receiving. During the transportation process, the wastewater in the sludge in the dewatering tank 4 passes through the arc-shaped filter plate. The water is filtered through filter 44 and then through the filter assembly on the collection box 5. The water undergoes double-layer filtration through filter screen 36, with secondary filter screen 38 passing through it multiple times in between, thus ensuring better filtration effect. The arc-shaped filter plate 44 is easy to disassemble and install. The clamping plate 42 is clamped into the clamping groove 40, and the side baffle 41 can be installed to ensure better interception of impurities in the water and good impurity collection effect. The filter assembly can be manually disassembled later to remove the impurities intercepted by the filter assembly. The collected water can be used to rinse the parts of the equipment. By activating the secondary electric telescopic rod 46, the squeezing plate 7 is driven to flip, and finally the squeezing plate 7 is horizontal, pressing the sheet-like internal sludge to complete the removal of internal water.
