Description

Technical Field

[0001] This utility model relates to the field of municipal solid waste treatment technology, specifically to an extrusion drying device for comprehensive municipal solid waste treatment. Background Technology

[0002] During the comprehensive treatment of municipal solid waste, dehydration is necessary due to its high water content. Existing waste dehydration devices mainly use belt conveyor extrusion devices, which use conveyor belts to transport waste and extrusion rollers to squeeze and dehydrate it. These devices typically have long production lines, occupy a large amount of space in the horizontal direction, and have high requirements for site area and layout. Furthermore, they suffer from insufficient stability in waste transportation over long distances.

[0003] In addition, there are also pressure-type waste dewatering devices on the market. The waste is placed into the dewatering tank below, and the water in the waste is squeezed out by the pressure plate. After a batch of waste is dewatered, the squeezed waste needs to be poured out and a new batch of waste to be dewatered needs to be loaded in. This results in frequent shutdowns, unloading and loading operations, which significantly prolongs the downtime, reduces the efficiency of continuous operation of the equipment, and the intermittent processing is difficult to adapt to the large-scale and continuous production needs of waste dewatering. Utility Model Content

[0004] The purpose of this utility model is to provide a compression drying device for comprehensive treatment of municipal solid waste, so as to solve the technical problems mentioned in the background art.

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

[0006] A dewatering device for comprehensive municipal solid waste treatment includes an outer tank, a cylindrical core, a drive mechanism, and dewatering units. The cylindrical core is installed inside the outer tank, with its top extending through to the top of the outer tank. Several dewatering units are evenly distributed in a ring array on the outer periphery of the cylindrical core. The drive mechanism is located at the top of the outer tank and is used to drive the cylindrical core to rotate. Each dewatering unit includes a fixed pressure plate and a moving pressure plate. The fixed pressure plate is fixed to the outer periphery of the cylindrical core. The moving pressure plate is elastically connected to one side of the fixed pressure plate and forms a dewatering cavity with the fixed pressure plate. Several leakage holes are evenly distributed at the bottom of the outer tank, and several water outlet holes are evenly distributed on the moving pressure plate. The outer tank is also provided with a pushing mechanism to push the moving pressure plate closer to the corresponding fixed pressure plate to reduce the space of the dewatering cavity and achieve waste dewatering.

[0007] Preferably, a feeding cylinder is connected to the top of the outer tank, and the feeding cylinder has a feeding port on one side of its top.

[0008] Preferably, the drive mechanism includes a drive motor A and a coupling; a mounting platform is fixed to the top of the outer tank by a pair of uprights, and the drive motor A is fixed on the mounting platform; the output shaft of the drive motor A is fixedly connected to the top shaft end of the cylindrical core through the coupling.

[0009] Preferably, an arc-shaped slide rod A and an arc-shaped slide rod B are fixed between two adjacent fixed pressure plates and near the top, respectively. The moving pressure plate has two sliding holes. The moving pressure plate is movably installed on the arc-shaped slide rod A and the arc-shaped slide rod B through the two sliding holes. Each arc-shaped slide rod B is fitted with a spring, one end of which is fixed to the moving pressure plate and the other end of which is fixed to the corresponding fixed pressure plate. A corrugated telescopic sleeve covering the spring is also fitted on the outside of the arc-shaped slide rod B. One end of the corrugated telescopic sleeve is fixed to the moving pressure plate and the other end of which is fixed to the corresponding fixed pressure plate.

[0010] Preferably, under the elastic support of the spring, the dynamic pressure plate is in contact with the fixed pressure plate in the adjacent extrusion dewatering group; when the dynamic pressure plate moves closer to the corresponding fixed pressure plate, a water collection cavity is formed between the dynamic pressure plate and the fixed pressure plate in the adjacent extrusion dewatering group; push rods are evenly distributed on the side of the fixed pressure plate near the fixed pressure plate in the adjacent extrusion dewatering group, and each push rod is conical; when the dynamic pressure plate is in contact with the corresponding fixed pressure plate, each push rod is respectively matched and inserted into the water outlet hole on the corresponding dynamic pressure plate.

[0011] Preferably, the top of the outer tank is provided with a relief groove, and each dynamic pressure plate has a stop block fixed at the position corresponding to the relief groove; the abutment and pushing mechanism includes a telescopic cylinder A and a baffle; the telescopic cylinder A is vertically fixed to the side of the outer tank by a mounting seat, and a suspension is fixed on the telescopic end of the telescopic cylinder A; a baffle is fixed below the suspension at the position corresponding to the relief groove; the baffle and the stop block abut against each other.

[0012] Preferably, the top of the outer tank has a fitting groove, and the bottom of the outer tank has a discharge port corresponding to the fitting groove. The outer tank is also equipped with a pushing mechanism, which is used to push the extruded and dehydrated waste in the extrusion chamber out of the discharge port. The pushing mechanism includes a telescopic cylinder B and a pushing plate. A bracket is fixed to the side of the outer tank, and the telescopic cylinder B is vertically fixed to the bracket. The telescopic end of the telescopic cylinder B is connected to the pushing plate through an L-shaped connecting arm. A guide groove is provided at the bottom of the outer tank below the discharge port.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0014] This device features a vertical layout, occupying minimal horizontal space. It performs extrusion dewatering within the tank, ensuring high operational stability. Furthermore, the extrusion dewatering unit uses a drive mechanism to rotate the cylindrical core, enabling position switching. Combined with an anti-pushing mechanism to prevent the moving pressure plate from approaching the fixed pressure plate, this extrusion dewatering design allows for continuous waste processing. This avoids the frequent shutdowns, unloading, and loading issues caused by the intermittent operation of down-pressing devices, significantly improving the continuous operation efficiency of the equipment.

[0015] In the extrusion dewatering unit, the dynamic pressure plate and the fixed pressure plate are elastically connected, and the arc-shaped slide bar B is externally fitted with a spring and a corrugated telescopic sleeve. After being squeezed by the pushing mechanism, the dynamic pressure plate can reset and expand the extrusion chamber space, causing the squeezed waste to collapse, which facilitates secondary extrusion and ensures more thorough dewatering and drying, thus solving the problem of insufficient dewatering in existing devices.

[0016] During the extrusion dewatering process, when the dynamic pressure plate moves closer to the corresponding fixed pressure plate to extrude waste, the distance between the dynamic pressure plate and the fixed pressure plate in the adjacent extrusion dewatering group increases, forming a water collection chamber. After the sewage flowing out of the outlet enters the water collection chamber, the large space inside the water collection chamber ensures that the sewage can be discharged quickly, avoiding excessive accumulation of sewage.

[0017] The pointed conical push rod on the fixed pressure plate is inserted into the water outlet when the moving pressure plate is reset. It can push back the accumulated dirt and avoid clogging the water outlet. Compared with the existing devices that are prone to clogging during the dehydration process, it effectively ensures dehydration efficiency and system stability. Attached Figure Description

Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized. Example 1

[0035] Please see Figures 1-11 The extrusion drying device provided by this utility model includes an outer tank 1, a cylindrical core 2, a drive mechanism 4, and an extrusion dehydration group 3. The top of the outer tank 1 is connected to a feeding cylinder 6. The top side of the feeding cylinder 6 has a feeding port 61. The garbage is placed in the feeding port 61 and then enters the outer tank 1 through the feeding cylinder 6 so that the garbage can be fed into the outer tank 1.

[0036] The cylindrical core 2 is installed inside the outer tank 1 and is rotatably connected to the outer tank 1. The top of the cylindrical core 2 extends through to the top of the outer tank 1. Several extrusion dewatering groups 3 are evenly distributed in a ring array on the outer periphery of the cylindrical core 2. The drive mechanism 4 is arranged on the top of the outer tank 1 and is used to drive the cylindrical core 2 to rotate so as to realize the position switching of the extrusion dewatering group 3. That is, the cylindrical core 2 is driven to rotate inside the outer tank 1 by the operation of the drive mechanism 4, which can synchronously drive each extrusion dewatering group 3 to rotate around the axis of the cylindrical core 2 inside the outer tank 1.

[0037] Specifically, such as Figures 3-7 As shown, the extrusion dewatering group 3 includes a fixed pressure plate 31 and a dynamic pressure plate 32. The fixed pressure plate 31 is fixed on the outer peripheral wall of the cylindrical core 2, and the dynamic pressure plate 32 is elastically connected to one side of the fixed pressure plate 31. That is, when the driving mechanism 4 drives the cylindrical core 2 and each extrusion dewatering group 3 to rotate, when the dynamic pressure plate 32 is blocked, it can overcome the elastic force and move relative to the fixed pressure plate 31 in the same extrusion dewatering group 3. After the blockage is removed, the dynamic pressure plate 32 can also move away from the fixed pressure plate 31 to reset.

[0038] In the same extrusion dewatering group 3, the dynamic pressure plate 32 and the fixed pressure plate 31 form an extrusion chamber 301. When the driving mechanism 4 drives the cylindrical core 2 and the extrusion dewatering group 3 to rotate, when the extrusion chamber 301 is aligned with the feeding cylinder 6, the organic waste in the feeding cylinder 6 can fall into the extrusion chamber 301 to realize waste disposal. In addition, the bottom of the outer tank 1 is evenly distributed with several leakage holes 11, and the dynamic pressure plate 32 is evenly distributed with several water outlet holes 321. The leakage holes 11 and the water outlet holes 321 are used to leak the extruded sewage.

[0039] The outer tank 1 is also equipped with a push-off mechanism 5. As the drive mechanism 4 drives the cylindrical core 2 and the extrusion dewatering group 3 to rotate, when the extrusion dewatering group 3 passes the push-off mechanism 5, the push-off mechanism 5 can push the dynamic pressure plate 32 to move closer to the corresponding fixed pressure plate 31, so that the space inside the corresponding extrusion chamber 301 is reduced, and the garbage inside the extrusion chamber 301 can be extruded and dewatered to achieve the drying treatment of the garbage. Part of the water is discharged directly through the seepage hole 11, and the other part of the water flows out through the water outlet hole 321 and is finally discharged through the seepage hole 11, thereby achieving the extrusion dewatering of the garbage.

[0040] like Figure 10 As shown, the bottom of the outer tank 1 has a discharge port 102, and the bottom of the outer tank 1 is provided with a guide trough 75 below the discharge port 102. During the process of the drive mechanism 4 driving the cylindrical core 2 and the extrusion and dewatering group 3 to rotate, when the fixed pressure plate 31 and the dynamic pressure plate 32 carry the extruded and dewatered garbage to the position aligned with the discharge port 102, the garbage falls from the discharge port 102 into the guide trough 75. The guide trough 75 is arranged at an inclination, which can guide the garbage to the outside.

[0041] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, an arc-shaped slide bar A33 and an arc-shaped slide bar B34 are fixed between two adjacent fixed pressure plates 31 and near the top, respectively. The arc-shaped slide bar A33 is located on the periphery of the arc-shaped slide bar B34 and has the same curvature, forming part of a circle. The moving pressure plate 32 has two sliding holes 322. The moving pressure plate 32 is movably mounted on the arc-shaped slide bar A33 and the arc-shaped slide bar B34 through the two sliding holes 322. One of the sliding holes 322 on the moving pressure plate 32 matches the arc-shaped slide bar A33, and the other sliding hole 322 on the moving pressure plate 32 matches the arc-shaped slide bar B34. This arrangement enables the moving pressure plate 32 to slide along the arc-shaped slide bar A33 and the arc-shaped slide bar B34.

[0042] In addition, each arc-shaped slide bar B34 is fitted with a spring 35. One end of the spring 35 is fixed to the moving pressure plate 32, and the other end is fixed to the corresponding fixed pressure plate 31, so that the moving pressure plate 32 and the corresponding fixed pressure plate 31 are elastically connected. When the pushing mechanism 5 blocks the moving pressure plate 32 from moving toward the fixed pressure plate 31, the spring 35 is compressed and stores force. When the pushing mechanism 5 releases the blocking force on the moving pressure plate 32, the spring 35 can push the moving pressure plate 32 to slide back to its original position, that is, expand the space of the squeezing chamber 301 to make room for the squeezed garbage to collapse downward.

[0043] Secondly, such as Figure 6 and Figure 7 As shown, the arc-shaped slide bar B34 is also fitted with a corrugated telescopic sleeve 36 that covers the spring 35. One end of the corrugated telescopic sleeve 36 is fixed to the moving pressure plate 32, and the other end is fixed to the corresponding fixed pressure plate 31. The corrugated telescopic sleeve 36 is used to cover and protect the spring 35 to prevent debris from splashing and getting stuck on the spring 35 and affecting the normal operation of the spring 35. At the same time, the corrugated telescopic sleeve 36 has the ability to extend, retract and bend to adapt to the positional changes when the moving pressure plate 32 moves.

[0044] Specifically, the top of the outer tank 1 is provided with a clearance groove 501, and each top of the dynamic pressure plate 32 is fixed with a stop block 55 at the position corresponding to the clearance groove 501. During rotation, the stop block 55 at the top of the dynamic pressure plate 32 can pass through the clearance groove 501 in sequence. The abutting and pushing mechanism 5 includes a telescopic cylinder A52 and a baffle 54. The telescopic cylinder A52 is vertically fixed to the side of the outer tank 1 through the mounting base 51. A suspension 53 is fixed on the telescopic end of the telescopic cylinder A52. A baffle 54 is fixed below the suspension 53 at the position corresponding to the clearance groove 501. The baffle 54 and the stop block 55 are in corresponding abutting cooperation.

[0045] The telescopic cylinder A52 retracts in advance, causing the suspension 53 and baffle 54 to move downward. The downward-moving baffle 54 passes through the relief groove 501 and reaches the moving path of the abutment 55 in advance. During the process of the drive mechanism 4 driving the cylindrical core 2 and the extrusion dewatering group 3 to rotate, when the abutment 55 at the top of the dynamic pressure plate 32 passes through the relief groove 501, the baffle 54 blocks and abuts the abutment 55, causing the dynamic pressure plate 32 to stop moving and then move to the side of the fixed pressure plate 31 to achieve extrusion dewatering.

[0046] By extending the suspension 53, the suspension 53 and the baffle 54 can be moved upward. The baffle 54 is dislodged from the relief groove 501 and separated from the abutment 55, thus canceling the obstruction and resistance to the dynamic pressure plate 32. Under the action of the spring 35, the dynamic pressure plate 32 can be pushed to reset.

[0047] like Figure 8As shown, there are two sets of clearance grooves 501, with two in each set. Similarly, there are two sets of baffles 54, with two in each set. Each dynamic pressure plate 32 has two abutments 55 on its top. When the dynamic pressure plate 32 is being squeezed, the two baffles 54 in one set simultaneously block and resist the corresponding two abutments 55, resulting in high stability. Since there are two sets of baffles 54, the waste in the squeezing chamber 301 can be continuously squeezed and dehydrated twice during one rotation of the cylindrical core 2.

[0048] Specifically, after the first compression and dehydration, the waste in the compression chamber 301 is flattened. As the spring 35 pushes the moving pressure plate 32 to reset and move away from the fixed pressure plate 31, the space inside the compression chamber 301 is reset. The originally flattened waste loses its lateral constraint, loosens under the action of gravity, and falls to fill the space at the bottom of the compression chamber 301. With the second compression action, the waste can be dehydrated again, thereby ensuring that the waste dehydration and drying process is more thorough.

[0049] like Figure 8 As shown, the drive mechanism 4 includes a drive motor A43 and a coupling 44. The top of the outer tank 1 is fixed with a mounting platform 42 by a pair of uprights 41. The drive motor A43 is fixed on the mounting platform 42. The output shaft of the drive motor A43 is fixedly connected to the top shaft end of the cylindrical core 2 through the coupling 44. The uprights 41 are used to fix the drive motor A43 on the mounting platform 42 above the outer tank 1. When the drive motor A43 works, its output shaft can drive the cylindrical core 2 to rotate under the transmission connection of the coupling 44, thereby providing a stable drive for the rotation of the cylindrical core 2. Example 2

[0050] Please see Figures 3-7 The difference between this embodiment and Embodiment 1 is that:

[0051] Under the elastic support of spring 35, the dynamic pressure plate 32 is in contact with the fixed pressure plate 31 in the adjacent extrusion and dehydration group 3, such as... Figure 11 As shown in the figure (the solid arrows in the figure indicate the direction of movement of the dynamic pressure plate 32 relative to the fixed pressure plate 31, and the dashed arrows indicate the direction of sewage extrusion), during the extrusion dewatering process, when the dynamic pressure plate 32 moves closer to the corresponding fixed pressure plate 31 to extrude the waste, the distance between the dynamic pressure plate 32 and the fixed pressure plate 31 in the adjacent extrusion dewatering group 3 increases, forming a water collection chamber 302. After the sewage flowing out of the water outlet 321 enters the water collection chamber 302, the large space inside the water collection chamber 302 ensures that the sewage can be discharged quickly, avoiding excessive accumulation of sewage.

[0052] Furthermore, during the dehydration process, some small-volume waste is squeezed into the water outlet 321, which can easily cause blockage. To solve this problem, the present invention makes the following improvements:

[0053] like Figure 4As shown, push rods 311 are evenly distributed on one side of the pressure plate 31 near the pressure plate 31 in the adjacent extrusion dewatering group 3. When the spring 35 pushes the moving pressure plate 32 to fit with the pressure plate 31 in another extrusion dewatering group 3, each push rod 311 can be inserted into the outlet hole 321 one by one, thereby pushing the dirt accumulated in the outlet hole 321 back into the extrusion chamber 301, thus achieving the purpose of cleaning the dirt in the outlet hole 321. Each push rod 311 is conical, that is, the head diameter of the push rod 311 is small, so that it can smoothly enter the outlet hole 321 during the resetting of the moving pressure plate 32, avoiding obstruction and interference. Example 3

[0054] Please see Figure 10 The difference between this embodiment and Embodiment 2 is that:

[0055] Specifically, the top of the outer tank 1 has a fitting groove 101 corresponding to the position of the discharge port 102. The outer tank 1 is also provided with a pushing mechanism 7. The pushing mechanism 7 is used to push the squeezed and dehydrated waste in the squeezing chamber 301 out from the discharge port 102. The pushing mechanism 7 includes a telescopic cylinder B72 and a pushing plate 74. A bracket 71 is fixed on the side of the outer tank 1. The telescopic cylinder B72 is vertically fixed on the bracket 71. The telescopic end of the telescopic cylinder B72 is connected to the pushing plate 74 through an L-shaped connecting arm 73.

[0056] When the waste, after being squeezed, dehydrated, and dried in the extrusion chamber 301, is discharged onto the guide trough 75, the telescopic cylinder B72 retracts. Under the connection of the L-shaped connecting arm 73, the pusher plate 74 is pushed down into the extrusion chamber 301, thereby pushing the waste in the extrusion chamber 301 downwards and discharging it. This accelerates the discharge of waste and ensures that the waste in the extrusion chamber 301 is discharged as completely as possible. After the waste is discharged, the telescopic cylinder B72 extends, which drives the pusher plate 74 to move upwards and reset. The pusher plate 74 finally returns to its position in the fitting groove 101, avoiding obstruction or interference to the rotation of the fixed pressure plate 31 and the dynamic pressure plate 32.

[0057] It is worth noting that the telescopic cylinders A52 and B72 in this application can be electric cylinders, hydraulic cylinders, or pneumatic cylinders, etc.

[0058] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0059] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
