Description

Technical Field

[0001] This utility model relates to the field of sludge dewatering machine technology, and in particular to a sludge uniform feeding and propulsion device for a screw press sludge dewatering machine. Background Technology

[0002] In the field of sludge dewatering, screw press sludge dewatering machines are widely used in sludge treatment scenarios in municipal sewage, industrial wastewater, and food processing industries due to their advantages such as adaptability to low-concentration sludge, small footprint, and ease of operation. Their core function lies in using a uniform feeding device to deliver the sludge evenly and stably to the dewatering area, ensuring the efficient execution of subsequent concentration and dewatering processes.

[0003] Existing screw press sludge dewatering machines generally suffer from two major technical bottlenecks when processing sludge containing fibers, particles, or high viscosity: Firstly, the traditional single-stage pushing structure is insufficient to fully disperse and homogenize the sludge, leading to sludge accumulation in the sludge storage tank. This is especially problematic when processing high-concentration or agglomerated sludge, as uneven flow resistance can easily cause transport interruptions. Secondly, at the sludge outlet pipe inlet, sludge particles often support each other, forming a "bridging" phenomenon (such as fiber entanglement or agglomeration of viscous substances), or the pipe wall adhesion reduces the cross-sectional area of ​​the channel, leading to blockages. To address these technical problems, this application proposes a sludge homogenizing and propulsive device for screw press sludge dewatering machines. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sludge equalization and propulsion device for a screw press sludge dewatering machine. The first and second sludge discharge plates rotate synchronously via a second synchronous belt, which guides the sludge to flow into the equalization tank, preventing it from accumulating in the storage tank. When the spiral plate rotates, the radial cutting force of the blades can directly impact the bridging structure, destroying the supporting force between particles, causing the arched sludge to collapse and be propelled by the spiral, preventing the sludge from stagnating and clogging due to high resistance.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A sludge uniform feeding and propulsion device for a screw press sludge dewatering machine includes a sludge storage tank. A sludge suction pipe is fixedly connected to the right end of the sludge storage tank. A stirring rod is rotatably connected to the inner wall of the sludge storage tank. A pushing assembly is connected to the front side of the outer wall of the stirring rod via a synchronous belt. A motor is mounted on the front end of the sludge storage tank via a fixed frame. The drive end of the motor is fixedly connected to the front end of the stirring rod. A uniform feeding box is fixedly connected to the left end of the sludge storage tank. A sludge discharge pipe is fixedly connected to the left end of the uniform feeding box. A rotating rod is rotatably connected to the top of the uniform feeding box. A spiral plate is connected to the outer wall of the rotating rod via a linkage assembly. The spiral plate is rotatably connected to the inner wall of the discharge pipe. A baffle is fixedly connected to the inner wall of the uniform feeding box.

[0007] Furthermore, the pushing assembly includes a mud discharge plate one located on the front side of the outer wall of the stirring rod and connected by a timing belt one. The front side of the outer wall of the mud discharge plate one is connected to a mud discharge plate two via a timing belt two. Both the mud discharge plate one and the mud discharge plate two are rotatably connected to the inner wall of the mud storage box.

[0008] Furthermore, the linkage assembly includes a bevel gear one located on the outer wall of the rotating rod one, a bevel gear two meshing at the bottom end of the bevel gear one, a rotating rod two fixedly connected at the bottom end of the bevel gear two, the rotating rod two being rotatably connected to the inner wall of the mud equalization box, a bevel gear three fixedly connected at the middle of the outer wall of the rotating rod two, a bevel gear four meshing at the left end of the bevel gear three, and the bevel gear four being fixedly connected to the right end of the spiral plate.

[0009] Furthermore, a protective box is rotatably connected to the outer wall of the rotating rod two, and the protective box two is fixedly connected to the inner wall of the mud equalization box. The bevel gear three and bevel gear four are both rotatably connected to the inner wall of the protective box two.

[0010] Furthermore, a protective box is rotatably connected to the outer wall of the rotating rod, and the protective box is fixedly connected to the top of the mud equalization box. Both the bevel gear one and the bevel gear two are rotatably connected to the inner wall of the protective box one.

[0011] Furthermore, a second motor is mounted on the front end of the protective box via a fixing frame, and the drive end of the second motor is fixedly connected to the front end of the rotating rod.

[0012] Furthermore, a water pump is installed on the outer wall of the sludge suction pipe.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, through the multi-stage transmission of the stirring rod, the first sludge discharge plate, and the second sludge discharge plate, a combination of "dispersing, shearing, and guiding" is formed. The first sludge discharge plate and the second sludge discharge plate rotate synchronously through the second synchronous belt, which can guide the sludge to flow into the sludge equalization box and avoid accumulation in the sludge storage box.

[0015] 2. In this utility model, when the sludge contains fibers, particles or sticky substances, it is easy to form a bridge at the inlet of the sludge outlet pipe, that is, the particles support each other to form an arched cavity, which hinders the subsequent flow of sludge. When the spiral plate rotates, the radial cutting force of the blades can directly impact the bridging structure, destroy the supporting force between the particles, cause the arched sludge to collapse and be propelled by the spiral, and prevent the sludge from stagnating and clogging due to high resistance.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3 An embodiment of this utility model provides a sludge uniform feeding and propulsion device for a screw press sludge dewatering machine, including a sludge storage box 1, a sludge suction pipe 2 fixedly connected to the right end of the sludge storage box 1, a stirring rod 4 rotatably connected to the inner wall of the sludge storage box 1, a sludge discharge plate 6 connected to the front side of the outer wall of the stirring rod 4 via a synchronous belt 5, a motor 3 mounted on the front end of the sludge storage box 1 via a fixed frame, the drive end of the motor 3 fixedly connected to the front end of the stirring rod 4, a uniform sludge box 11 fixedly connected to the left end of the sludge storage box 1, a sludge discharge pipe 12 fixedly connected to the left end of the uniform sludge box 11, a rotating rod 10 rotatably connected to the top of the uniform sludge box 11, a spiral plate 20 connected to the outer wall of the rotating rod 10 via a bevel gear 14, a bevel gear 25, a rotating rod 26, a bevel gear 37, and a bevel gear 49, the spiral plate 20 rotatably connected to the inner wall of the sludge discharge pipe 12, and a baffle 21 fixedly connected to the inner wall of the uniform sludge box 11;

[0025] Specifically, the sludge discharge pipe 12 is connected to the sludge inlet port of the screw press sludge dewatering machine to form a sludge conveying channel. The motor 29 drives the rotating rod 10 to rotate. The bevel gear 14 on the rotating rod 10 meshes with the bevel gear 25, driving the rotating rod 26 to rotate. The rotating rod 26 is driven by the meshing of the bevel gear 317 and the bevel gear 419, which drives the spiral plate 20 to rotate inside the sludge discharge pipe 12. This pushes the sludge in the equalization box 11 to the screw press dewatering machine at a uniform speed. The continuous rotation of the spiral plate 20 can clean the sludge adhering to the inner wall of the sludge discharge pipe 12 in real time. In conjunction with the baffle 21 in the equalization box 11, it guides the sludge flow direction, avoids sludge stagnation and accumulation, and ensures a continuous and stable conveying process.

[0026] Reference Figure 2 , Figure 4 and Figure 5 The mixing rod 4 has a mud discharge plate 6 connected to the front of its outer wall via a timing belt 5. The mud discharge plate 6 is connected to a mud discharge plate 8 via a timing belt 7. Both mud discharge plates 6 and 8 are rotatably connected to the inner wall of the mud storage tank 1. A bevel gear 14 is located on the outer wall of the rotating rod 10. A bevel gear 15 is meshed at the bottom of bevel gear 14. A rotating rod 16 is fixedly connected to the bottom of bevel gear 15. The rotating rod 16 is rotatably connected to the inner wall of the mud equalization tank 11. A bevel gear 17 is fixedly connected to the middle of the outer wall of the rotating rod 16. A bevel gear 19 is meshed at the left end of bevel gear 17. The right end of the fixed spiral plate 20 is connected to the outer wall of the rotating rod 2 16, and the protective box 2 18 is rotatably connected to the outer wall of the mud equalization box 11. The bevel gear 3 17 and bevel gear 4 19 are rotatably connected to the inner wall of the protective box 2 18. The outer wall of the rotating rod 1 10 is rotatably connected to the protective box 1 13, and the protective box 1 13 is fixedly connected to the top of the mud equalization box 11. The bevel gear 1 14 and bevel gear 2 15 are rotatably connected to the inner wall of the protective box 13. The front end of the protective box 1 13 is equipped with a motor 2 9 through a fixing frame. The drive end of the motor 2 9 is fixedly connected to the front end of the rotating rod 1 10. A water pump is provided on the outer wall of the mud pumping pipe 2.

[0027] Specifically, the motor 3 is started, and its drive end drives the stirring rod 4 to rotate clockwise. The blades of the stirring rod 4 rotate and break up the sludge clumps, making them initially uniform. The stirring rod 4 transmits power to the sludge discharge plate 6 through the synchronous belt 5, making it rotate synchronously. When the sludge discharge plate 6 rotates, the blades push the sludge on the right side of the sludge storage box 1 to the left to the vicinity of the sludge discharge plate 8. The sludge discharge plate 6 drives the sludge discharge plate 8 to rotate clockwise through the synchronous belt 7, further breaking up the sludge flocs and distributing the material evenly, so that the sludge flows smoothly into the sludge equalization box 11 on the left. The water pump outside the sludge suction pipe 2 is turned on, and the sludge is sucked into the sludge storage box 1 from the outside under the action of negative pressure.

[0028] Working principle: Connect the sludge discharge pipe 12 to the screw press sludge dewatering machine. Then, start the motor 3 to drive the stirring rod 4 to rotate. Next, start the water pump to suck the sludge into the sludge storage tank 1 through the sludge suction pipe 2. The stirring rod 4 disperses the sludge. As the stirring rod 4 rotates, it drives the discharge plate 6 to rotate via the synchronous belt 5. The discharge plate 6 moves the sludge to the discharge plate 8. Then, under the action of the synchronous belt 7, the rotation of discharge plate 6 drives the discharge plate 8 to rotate, thus... The second sludge discharge plate 8 allows the sludge to flow more smoothly into the equalization tank 11. Then, under the action of the second motor 9, it will drive the first rotating rod 10 to rotate. The first rotating rod 10 will drive the first bevel gear 14 to rotate. When the first bevel gear 14 rotates, it will drive the second rotating rod 16 to rotate through the second bevel gear 15, which in turn will drive the third bevel gear 17 to rotate the fourth bevel gear 19, thereby causing the spiral plate 20 to rotate. This can prevent the sludge from getting clogged when it enters the screw press sludge dewatering machine through the sludge discharge pipe 12.
