Description

Technical Field

[0001] This utility model relates to the field of sludge and waste conveying technology, and in particular to a conveying device for sludge and domestic waste treatment. Background Technology

[0002] With the acceleration of urbanization and the improvement of residents' living standards, the generation of sewage sludge and domestic waste has exploded, becoming a core problem restricting the sustainable development of the urban ecological environment. As the artery system of the entire sewage sludge and domestic waste treatment process, the efficiency and stability of the transportation link directly determine the effectiveness of subsequent treatment processes.

[0003] When transporting waste, the height of the conveying device needs to be adjusted to match upstream and downstream equipment in different site or equipment layouts. The conveying device may need to operate at a non-optimal height for extended periods and may require frequent adjustments or replacements to adapt to different working environments. This leads to decreased conveying efficiency, frequent wear and tear on the device, and even premature equipment failure, increasing maintenance and replacement costs and affecting the efficiency of waste or sludge treatment. After waste and sludge are transported, residual material inside the device can easily breed bacteria and emit foul odors. Dry material dust may also spread around the equipment, and sludge or waste may adhere to the inside of the conveying device, causing clumping and blockage of pipes or conveying channels, affecting normal operation. Frequent wear and tear may lead to premature equipment failure, increasing maintenance and replacement costs, and reducing conveying speed. Utility Model Content

[0007] Furthermore, a feed hopper is connected through the left side of the front side wall of the cylinder, a protective box is fixedly connected to the top left side of the cylinder, a chain box is threadedly connected to the left side wall of the cylinder, a control panel is fixedly connected to the front side wall of the chain box, a chain is installed inside the chain box, and a second motor is installed inside the protective box.

[0008] Furthermore, a rotating rod is fixedly connected to the output end of the second motor, and a first sprocket is fixedly connected to the outer side of the left end of the rotating rod. The outer side of the first sprocket meshes with the inside of the chain. A helical rod is rotatably connected inside the cylinder, and a second sprocket is fixedly connected to the outer side of the left end of the helical rod. The outer side of the second sprocket meshes with the inside of the chain.

[0009] Furthermore, a discharge box is connected through the bottom right side of the cylinder, a sieve plate is fixedly connected inside the bottom wall of the cylinder, a collection box is fixedly connected to the bottom of the cylinder, the collection box is located on the bottom outside of the sieve plate, and a sewage pipe is connected through the left side of the collection box.

[0010] Furthermore, a fixing plate is fixedly connected to the rear side wall of the cylinder, a pump is provided on the top of the fixing plate, a first connecting pipe is fixedly connected to the input end of the pump, and a delivery pipe is fixedly connected to the output end of the pump.

[0011] Furthermore, the top of the conveying pipe is connected to a transfer pipe, the front end of the transfer pipe is connected to a spray pipe, the top of the spray pipe is fixedly connected to the inner top wall of the cylinder, and the bottom of the spray pipe is connected to an inner pipe.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1.

By incorporating a pump, conveying pipe, triplet pipe, spray pipe, external connecting pipe, second connecting pipe, and nozzles, the system effectively addresses issues such as pipe or conveying channel blockages, which disrupt normal operation, frequent wear leading to premature equipment failure, increased maintenance and replacement costs, and reduced conveying speed. The liquid flows sequentially through the internal connecting pipe at the bottom, the external connecting pipe, and the second connecting pipe, finally exiting from the nozzles in a mist or columnar spray pattern, evenly covering the material inside the cylinder and the surface of the screw. On one hand, the sprayed liquid moistens the dry material, reducing its viscosity and preventing it from adhering and accumulating on the screw blades, ensuring smooth conveying. On the other hand, it provides preliminary dilution of the material, facilitating subsequent screening and separation by the sieve plate. This effectively reduces the risk of blockages within the conveying device, ensuring smooth conveying, extending equipment lifespan, and improving conveying speed and processing efficiency.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1 - Figure 6The image shows a conveying device for treating sludge and domestic waste, comprising a cylindrical body 1. The device is characterized in that a support frame 2 is rotatably connected to the outer side of the left end of the cylindrical body 1. The support frame 2 supports the left end of the cylindrical body 1 and, in conjunction with the device on the right side, supports and fixes the device on the right side at different heights. A device box 3 is provided at the bottom of the right end of the cylindrical body 1, providing external protection for the internal device. A first motor 4 is installed on the right side inside the device box 3. A lead screw 5 is fixedly connected to the output end of the first motor 4. A support ring 6 is fixedly connected to the left side wall inside the device box 3. The outer left end of the lead screw 5 is rotatably connected to the inside of the support ring 6. A sleeve 7 is slidably connected to the outer side of the lead screw 5. An outer cylinder 8 is fixedly connected to the outer side of the sleeve 7. When the first motor 4 is energized, it drives the lead screw 5 at its output end to rotate. The outer left end of the lead screw 5 is rotatably connected to the inside of the support ring 6, thereby supporting the left end of the lead screw 5 and ensuring that the lead screw 5 rotates only along its own axis without deflection. Under the rotation of the lead screw 5, the inside of the sleeve 7 will mesh with the outer side of the lead screw 5, thereby driving the sleeve 7 to slide left and right on the outer side of the lead screw 5, and thus driving the outer cylinder 8 fixedly connected to the sleeve 7 to move synchronously, providing linear driving force for angle adjustment.

[0020] A first support rod 9 is rotatably connected to the top outer side of the outer cylinder 8. A connecting column 10 is rotatably connected to the top of the first support rod 9. A first hinge frame 11 is fixedly connected to the bottom right end of the cylinder 1. The front and rear ends of the connecting column 10 are rotatably connected to the inside of the first hinge frame 11. A second hinge frame 12 is fixedly connected to the left side inside the device box 3. A second support rod 13 is rotatably connected to the inside of the second hinge frame 12. The other side of the second support rod 13 is rotatably connected to the middle of the first support rod 9. Universal wheels 14 are fixedly connected to the bottom of both the support frame 2 and the device box 3. When the sleeve 7 moves left and right with the lead screw 5, the first support rod 10, which is rotatably connected to the top of the outer cylinder 8, is... The support rod 9 moves synchronously; the top of the first support rod 9 is rotatably connected to the inside of the first hinge frame 11 at the bottom right end of the cylinder 1 through the connecting column 10, and at the same time, the middle part of the first support rod 9 and the second support rod 13 connected inside the second hinge frame 12 form a triangular support structure. When the sleeve 7 moves to the right, the first support rod 9 is pushed upward under the limiting support of the second support rod 13, and the right end of the cylinder 1 is lifted upward through the connecting column 10, so that the cylinder 1 tilts counterclockwise about the rotation connection point of the left end support frame 2 as the axis, increasing the conveying angle; when the sleeve 7 moves to the left, the first support rod 9 is pulled downward, the right end of the cylinder 1 descends, and the conveying angle decreases.

[0021] like Figure 1 - Figure 7As shown, a feed hopper 15 is connected through the left side of the front wall of the cylinder 1, through which sludge and garbage are fed into the interior of the cylinder 1. A protective box 16 is fixedly connected to the top left side of the cylinder 1, and a chain box 17 is threadedly connected to the left side wall of the cylinder 1. The protective box 16 provides external protection for the second motor 20 inside, and the chain box 17 provides external protection for the chain 19, the first sprocket 22, and the second sprocket 24 inside.

[0022] A control panel 18 is fixedly connected to the front wall of the chain box 17, and the entire device is controlled through the control panel 18. A chain 19 is installed inside the chain box 17, and a second motor 20 is installed inside the protective box 16. A rotating rod 21 is fixedly connected to the output end of the second motor 20. A first sprocket 22 is fixedly connected to the outer side of the left end of the rotating rod 21. The outer side of the first sprocket 22 meshes with the inside of the chain 19. A spiral rod 23 is rotatably connected inside the cylinder 1. A second sprocket 24 is fixedly connected to the outer side of the left end of the spiral rod 23. The outer side of the second sprocket 24 meshes with the inside of the chain 19. After the device is started, the second motor 20 is energized and runs. The output end directly drives the rotating rod 21 to rotate synchronously; the first sprocket 22 on the outer left side of the rotating rod 21 rotates with the rotating rod 21. Since the first sprocket 22 is meshed with the chain 19 inside the chain box 17, the chain 19 forms a closed-loop transmission under the drive of the first sprocket 22; at the same time, the chain 19 meshes with the second sprocket 24 on the left side of the spiral rod 23 inside the cylinder 1, thereby driving the spiral rod 23 to rotate at high speed inside the cylinder 1, and through the spiral rod 23, it drives the sludge and garbage that enters the cylinder 1 from the feed hopper 15 to be transported to the right end.

[0023] like Figure 1 - Figure 3 As shown, a discharge box 25 is connected through the bottom right side of the cylinder 1. A sieve plate 26 is fixedly connected inside the bottom wall of the cylinder 1. A collection box 27 is fixedly connected to the bottom of the cylinder 1. The collection box 27 is located on the bottom outer side of the sieve plate 26. A drain pipe 28 is connected through the left side of the collection box 27. During the process of conveying materials by the screw rod 23, the materials continuously come into contact with the sieve plate 26 fixed inside the bottom wall of the cylinder 1, so that the sludge, sewage and fine particles in the garbage are screened out. The screened liquid and fine particles fall into the collection box 27 below. When the liquid or fine particles in the collection box 27 reach a certain amount, the channel of the drain pipe 28 is opened to discharge them.

[0024] like Figure 1 - Figure 10As shown, a fixing plate 29 is fixedly connected to the rear side wall of the cylinder 1. A pump 30 is provided on the top of the fixing plate 29. The fixing plate 29 provides bottom support for the pump 30 at the top and fixes the pump 30 to the rear side wall of the cylinder 1. The pump 30 has a first connecting pipe 31 fixedly connected to its input end and a delivery pipe 32 fixedly connected to its output end. The top of the delivery pipe 32 is connected to a transfer pipe 34, and the front end of the transfer pipe 34 is connected to a spray pipe 35. The top of the spray pipe 35 is fixedly connected to the inner top wall of the cylinder 1, and the bottom of each spray pipe 35 is connected to an inner pipe 36. Each inner pipe 36 has an outer pipe 37 threadedly connected to its bottom end. Each outer pipe 37 has a second connecting pipe 38 installed inside, and each second connecting pipe 38 has a nozzle 33 fixedly connected to its bottom end. When the pump 30 is powered on, its internal impeller rotates at high speed to generate negative pressure, drawing clean water from the outside into the pump 30 through the first connecting pipe 31 at the input end. At the same time, the rotation of the impeller applies centrifugal force to the water, giving it high-pressure kinetic energy, which is then directed through the delivery pipe 32 at the output end of the pump 30. High-pressure water flows through the delivery pipe 32 into the transfer pipe 34, which is connected to the top of the delivery pipe 32 and its front end is connected to the spray pipe 35, leading to the interior of the spray pipe 35. The spray pipe 35 is fixedly connected to the inner top wall of the cylinder 1 to prevent the outer pipe 37 and nozzles 33 at the bottom of the spray pipe 35 from contacting the surface of the spiral rod 23, which could cause damage to the nozzles 33, etc. It provides precise spray cleaning to the interior of the cylinder 1 and the exterior of the spiral rod 23. The bottom end of the inner pipe 36 is internally threaded with the outer pipe 37 for easy disassembly and maintenance. When the outer pipe 37 or nozzle 33 is blocked or damaged, it can be directly rotated and disassembled for replacement.

[0025] In addition, the second connecting pipe 38 inside the outer pipe 37 plays a role in guiding and stabilizing the flow, preventing pressure loss caused by changes in pipe diameter during the transmission of high-pressure water, ensuring that the water flow can be stably delivered to the nozzle 33 at the bottom, and spraying water out through the nozzle 33 to clean the inside of the cylinder 1 and the surface of the spiral rod 23.

[0026] It should be noted that this utility model is a conveying device for sludge and domestic waste treatment. First, the first motor 4, control panel 18, second motor 20, and pump 30 are connected to an external power source to supply power to the device.

[0027] When it is necessary to raise the right end of the cylinder to increase the conveying height, the first motor 4 on the right side inside the device box 3 is started through the control panel 18. The output end of the first motor 4 drives the lead screw 5 to rotate. Since the outer left end of the lead screw 5 is rotatably connected to the support ring 6 on the left side wall inside the device box 3, the support ring 6 provides stable support for the lead screw 5, ensuring that it does not deviate when rotating.

[0028] The sleeve 7, which is slidably connected to the outside of the lead screw 5, moves left and right along the axis of the lead screw as the lead screw 5 rotates, and the outer cylinder 8, which is fixed to the outside of the sleeve 7, moves synchronously. The first support rod 9, which is rotatably connected to the top of the outer cylinder 8, is rotatably connected to the first hinge frame 11 at the bottom right end of the cylinder 1 through the connecting column 10. At the same time, the middle part of the first support rod 9 is rotatably connected to the second support rod 13, which is rotatably connected to the second hinge frame 12 on the left side inside the device box 3, forming a support linkage. When the outer cylinder 8 drives one end of the first support rod 9 to move, the first support rod 9 rotates around the connection point with the second support rod 13 as the fulcrum, thereby pushing the right end of the cylinder 1 to rise or fall, realizing flexible adjustment of the conveying angle of the cylinder 1 and meeting the conveying needs of different heights.

[0029] The power source for material conveying comes from the second motor 20 inside the protective box 16. When the second motor 20 starts, its output drives the rotating rod 21 to rotate. Since the first sprocket 22 is fixedly connected to the outer left end of the rotating rod 21, and the first sprocket 22 meshes with the chain 19 inside the chain box 17, the power is transmitted through the chain 19 to the second sprocket 24 on the outer left end of the screw rod 23, thereby driving the screw rod 23 to rotate synchronously inside the cylinder 1. The material entering the cylinder moves from left to right along the axis of the cylinder 1 under the thrust generated by the rotation of the screw rod 23. During the process of the material being conveyed to the right with the screw rod 23, the screening and separation operations are completed simultaneously. This process is achieved by the sieve plate 26 inside the bottom wall of the cylinder 1 and the collection box 27 at the bottom of the cylinder 1. The sieve plate 26 has sieve holes of a specific aperture. When the material passes through, water, fine particulate impurities, etc. in the sludge can fall through the sieve holes and enter the collection box 27 located on the outer bottom of the sieve plate 26, completing the preliminary solid-liquid separation and coarse-fine particle separation.

[0030] The liquid and fine impurities collected in the collection box 27 can be discharged periodically through the drain pipe 28 on the left side of the collection box 27 to avoid accumulation and blockage; while large pieces of material that cannot pass through the screen holes of the sieve plate 26 continue to move to the right end of the cylinder 1 under the push of the screw rod 23, and are finally discharged through the discharge box 25 at the bottom right side of the cylinder 1, thus completing the material conveying and grading process.

[0031] The pump 30 is turned on via the control panel 18. The pump 30 draws external water or cleaning fluid through the first connecting pipe 31, and delivers the liquid to the transfer pipe 34 via the output pipe 32. The liquid is then diverted from the transfer pipe 34 to the front-end connected spray pipe 35.

[0032] After entering the spray pipe 35, the liquid flows through the inner pipe 36 at its bottom, then sequentially through the outer pipe 37 and the second connecting pipe 38, and finally is sprayed out from the nozzle 33 in a mist or column shape, evenly covering the material inside the cylinder 1 and the surface of the screw rod 23. On the one hand, the sprayed liquid can moisten the dry material, reduce its viscosity, and prevent it from adhering and accumulating on the blades of the screw rod 23, ensuring smooth conveying; on the other hand, it can preliminarily dilute the material, facilitating subsequent screening and separation by the sieve plate 26.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
