Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to a sludge dewatering and drying device. Background Technology

[0002] During land remediation, river sludge often contains a large amount of water. If it is dumped directly without treatment, it can easily cause sewage leakage, polluting the surrounding soil and groundwater. Dehydration and drying can effectively reduce the water content of the sludge, reduce its potential pollution risk to the environment, and the volume of the dehydrated and dried sludge is greatly reduced, making it easier to transport and dispose of. It can be better used for land backfilling, soil improvement, etc., improving the efficiency of land remediation and creating favorable conditions for the rational development and utilization of land resources.

[0003] The prior art patent CN222064337U discloses a hollow paddle sludge dryer, in which sludge is added through a feed funnel and flows into a drying tank. The sludge is dried by rotating and stirring the hollow paddles and stirring blocks. The generated water vapor is discharged through multiple sets of one-way vent valves. Finally, the dried sludge is discharged through a discharge hopper. However, during use, river sludge often contains stones and other debris. If this sludge containing stones and other debris is directly put into the equipment for dehydration and drying, strong friction and collision between the stones and the paddles, the inner wall of the dryer and other parts may occur, reducing the service life of the equipment. In fact, stones and other debris may even get stuck between the paddles, in the feed port, the discharge port or other parts of the dryer, causing the equipment to jam and fail to operate normally. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a sludge dewatering and drying device, which solves the problem that directly feeding river sludge mixed with stones and other debris into the device for dewatering and drying will affect the device's service life and may even cause the device to jam and malfunction.

[0006] Preferably, the control component includes a protective box fixedly installed on the bottom of the fixed plate. The top of the fixed plate has a mounting hole, in which a hollow rotating shaft is rotatably installed. A connecting plate is fixedly sleeved on the hollow rotating shaft. Multiple connecting holes are evenly distributed on the top of the connecting plate. Multiple connecting rods are evenly fixedly installed on the bottom of the sieve cylinder. The multiple connecting rods are slidably installed in the multiple connecting holes respectively. A vertical rotating shaft is rotatably installed on the bottom inner wall of the protective box. The top of the vertical rotating shaft passes through the hollow rotating shaft and is fixedly installed with an internal hexagon socket. A hexagonal plug is fixedly installed on the bottom end of the stirring shaft. The hexagonal plug is slidably installed in the internal hexagon socket. A power unit for driving the hollow rotating shaft and the vertical rotating shaft to rotate simultaneously in opposite directions is installed on the protective box.

[0007] Preferably, the power unit includes a control motor fixedly installed on the side of the protective box, the output end of the control motor extends into the protective box and is fixedly installed with a first bevel gear, and a second bevel gear is fixedly sleeved on both the hollow rotating shaft and the vertical rotating shaft, and both second bevel gears mesh with the first bevel gear.

[0008] Preferably, the fixing unit includes a mounting rod fixedly installed on the bottom of the annular seat, a mounting sleeve fixedly installed on the top of the fixing plate, the bottom end of the mounting rod being adapted to slide within the mounting sleeve, a sliding hole being provided on the side of the mounting sleeve, a fixing rod being slidably installed within the sliding hole, a fixing insertion hole being provided on the side of the mounting rod, one end of the fixing rod extending into the fixing insertion hole, a pull block being fixedly installed on the other end of the fixing rod, and a reset element for automatically resetting by pulling the pull block being installed on the mounting sleeve.

[0009] Preferably, the reset element includes a reset spring, with its two ends fixedly mounted on the sides of the mounting sleeve and the pull block that are close to each other.

[0010] Preferably, a guide bucket is fixedly installed on the inner wall of the feed inlet, the guide bucket is located directly above the screen cylinder, and an inspection port is opened on the outer periphery of the feed inlet, and a matching inspection door is rotatably installed in the inspection port.

The two connecting gears are meshed with each other, and the drive gear meshes with one of the connecting gears.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. When the control motor is started, the hollow rotating shaft and the vertical rotating shaft will rotate simultaneously in opposite directions through the first bevel gear and two second bevel gears. The rotation of the hollow rotating shaft will drive the screen cylinder to rotate together through the connecting plate and connecting rod, generating centrifugal force. This will cause smaller sludge particles to be thrown out of the screen cylinder through the screen holes and then fall into the equipment through the feed inlet for dewatering and drying. Larger stones and other impurities cannot pass through the screen holes and will remain in the screen cylinder, thus separating the sludge from the stones. This effectively avoids a series of operational problems caused by stones and other impurities being fed into the equipment together. During this process, the reverse rotation of the vertical rotating shaft will drive the stirring shaft to rotate in the opposite direction through the internal hexagonal socket and hexagonal plug. This will drive the stirring rod to crush and disperse the sludge lumps, improve the dispersion of the sludge, and allow the sludge to pass through the screen holes more effectively, thus improving the screening efficiency and effect. It has good practicality.

[0014] 2. With the cooperation of the fixing unit, when the pull block is pulled outward or released, the fixing rod can be driven to disengage or automatically insert into the fixing hole under the cooperation of the reset spring. Thus, the mounting rod can be loosened or fixed in the mounting sleeve. When the mounting rod is in the loose state, the inspection door can be opened to directly remove the screen cylinder from the inspection port, and the stones and other impurities inside can be cleaned or directly replaced, which is more practical.

[0022] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0023] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 - Appendix Figure 6 The present invention will be further described below.

[0024] A sludge dewatering and drying device includes a base 1 and a housing 2. Two horizontal rotating holes are provided on each of the two mutually distant sides of the housing 2. Hollow rotating shafts 4 are rotatably installed in each pair of corresponding horizontal rotating holes. Multiple matching hollow paddles 7 are evenly fixedly installed on the two hollow rotating shafts 4. It should be noted that using hollow rotating shafts 4 and hollow paddles 7 for sludge dewatering and drying is a mature existing technology, such as the KJG78 hollow paddle sludge dryer; therefore, its specific structure and operating principle will not be described in detail here. A drive assembly for driving the two hollow rotating shafts 4 to rotate simultaneously in opposite directions is installed on the base 1. The drive assembly includes a drive motor 3 fixedly installed on the top of the base 1. A drive gear 29 is fixedly installed at the output end of the drive motor 3. The two hollow rotating shafts 4... Each is fixedly fitted with a connecting gear 30, and the two connecting gears 30 are meshed with each other. The drive gear 29 meshes with one of the connecting gears 30. The top of the equipment housing 2 is fixedly installed with a feed inlet 5, and the bottom of the equipment housing 2 is fixedly installed with a discharge outlet and a drain outlet. When sludge is fed into the hollow rotating shaft 4 through the feed inlet 5, hot fluid can be introduced into the hollow rotating shaft 4 and the drive motor 3 can be started. The operation of the drive motor 3 will drive the drive gear 29 to rotate. The rotation of the drive gear 29 will drive one of the connecting gears 30 meshed with it to rotate together. The rotation of one connecting gear 30 will drive the other connecting gear 30 to rotate in opposite directions at the same time. In turn, the two hollow rotating shafts 4 can rotate in opposite directions at the same time. At this time, the hollow paddle 7 will rotate together with the hollow rotating shaft 4 to stir, squeeze and heat the sludge, so as to achieve the dewatering and drying treatment of the sludge.

[0025] like Figures 3 to 5As shown, a fixing plate 8 is fixedly installed on the inner wall of the feed inlet 5. A screen cylinder 10 is positioned directly above the fixing plate 8. A central rotating hole is opened at the bottom of the screen cylinder 10, and a stirring shaft 11 is rotatably installed in the central rotating hole. Multiple stirring rods 12 located inside the screen cylinder 10 are evenly fixedly installed on the stirring shaft 11. A T-shaped rotating ring 13 is fixedly installed at the bottom of the screen cylinder 10, and a matching annular seat 14 is rotatably sleeved on the T-shaped rotating ring 13. A control component for driving the screen cylinder 10 and the stirring shaft 11 to rotate simultaneously in opposite directions is installed on the fixing plate 8. The control component includes a protective box 9 fixedly installed on the bottom of the fixing plate 8. A mounting rotating hole is opened at the top of the fixing plate 8, and a hollow rotating shaft 15 is rotatably installed in the mounting rotating hole. A connecting plate 18 is fixedly sleeved on the hollow rotating shaft 15, and multiple connecting holes are evenly opened at the top of the connecting plate 18. Multiple connecting rods are evenly fixedly installed at the bottom of the screen cylinder 10. 17. Multiple connecting rods 17 are slidably installed in multiple connecting holes. A vertical rotating shaft 16 is rotatably installed on the bottom inner wall of the protective box 9. The top of the vertical rotating shaft 16 passes through the hollow rotating shaft 15 and is fixedly installed with an internal hexagon socket 19. There is a gap between the hollow rotating shaft 15 and the vertical rotating shaft 16, so that there will be no interference when they rotate. A hexagon plug 20 is fixedly installed at the bottom of the stirring shaft 11. The hexagon plug 20 is slidably installed in the internal hexagon socket 19. A power unit for driving the hollow rotating shaft 15 and the vertical rotating shaft 16 to rotate in opposite directions at the same time is installed on the protective box 9. Two fixing units for fixing the ring seat 14 are symmetrically installed on the fixing plate 8. An inspection port is opened on the outer periphery of the feed port 5. A matching inspection door 6 is rotatably installed in the inspection port, so that the staff can open the inspection door 6 and take out the screen cylinder 10 through the inspection port for cleaning or maintenance and replacement.

[0026] Specifically, when the operating power unit drives the hollow rotating shaft 15 and the vertical rotating shaft 16 to rotate in opposite directions simultaneously, the rotation of the hollow rotating shaft 15 will drive the screen cylinder 10 to rotate together through the connecting plate 18 and the connecting rod 17. The rotation of the screen cylinder 10 will generate centrifugal force, which can throw smaller sludge particles out of the screen cylinder 10 through the screen holes, and then fall into the equipment through the feed port 5 for dewatering and drying. Larger stones and other impurities cannot pass through the screen holes and will remain in the screen cylinder 10, thus achieving the separation of sludge and stones. This effectively avoids a series of operational problems caused by stones and other impurities being put into the equipment together. At the same time, the reverse rotation of the vertical rotating shaft 16 will drive the stirring shaft 11 to rotate in the opposite direction through the internal hex socket 19 and the hex plug 20. The reverse rotation of the stirring shaft 11 will drive the stirring rod 12 to crush and disperse the sludge blocks, improve the dispersion of the sludge, and allow the sludge to pass through the screen holes better, effectively improving the screening efficiency and effect.

[0027] like Figure 4 and Figure 5As shown, the power unit includes a control motor 21 fixedly installed on the side of the protective box 9. The control motor 21 is located directly below the fixed plate 8. The output end of the control motor 21 extends into the protective box 9 and is fixedly installed with a first bevel gear 22. A second bevel gear 23 is fixedly sleeved on both the hollow rotating shaft 15 and the vertical rotating shaft 16. Both second bevel gears 23 mesh with the first bevel gear 22. The two second bevel gears 23 are arranged symmetrically about the first bevel gear 22.

[0028] Specifically, when the control motor 21 is started, it will drive the first bevel gear 22 to rotate. Due to the gear meshing principle, the rotation of the first bevel gear 22 will drive the two second bevel gears 23 meshing with it to rotate in opposite directions, thereby achieving the purpose of driving the hollow rotating shaft 15 and the vertical rotating shaft 16 to rotate in opposite directions at the same time.

[0029] like Figure 3 , Figure 4 and Figure 6 As shown, the fixing unit includes a mounting rod 24 fixedly installed on the bottom of the annular seat 14, a mounting sleeve 25 fixedly installed on the top of the fixing plate 8, the bottom end of the mounting rod 24 being adapted to slide within the mounting sleeve 25, a sliding hole being provided on the side of the mounting sleeve 25, a fixing insert rod 26 being slidably installed in the sliding hole, a fixing insertion hole being provided on the side of the mounting rod 24, the position and size of the fixing insertion hole being adapted to the fixing insert rod 26, one end of the fixing insert rod 26 extending into the fixing insertion hole, and a pull block 27 being fixedly installed on the other end of the fixing insert rod 26, a reset element for automatically resetting the pull block 27 being installed on the mounting sleeve 25, the reset element including a reset spring 28, the two ends of the reset spring 28 being fixedly installed on the sides of the mounting sleeve 25 and the pull block 27 that are close to each other, and the reset spring 28 being in a stretched state.

[0030] Specifically, when the pull block 27 is pulled outward, the return spring 28 will deform, and the fixed rod 26 will gradually move out of the fixed insertion hole until the fixed rod 26 is completely detached from the fixed insertion hole. Then the installation rod 24 can be released. At this time, the screen cylinder 10 can be removed directly to clean or replace the stones and other impurities inside. After cleaning or replacement, the screen cylinder 10 can be taken out and the installation rod 24 can be inserted into the installation sleeve 25. Then the pull block 27 can be released. At this time, under the elastic force of the return spring 28, the pull block 27 will be pulled inward to automatically reset, which will drive the fixed rod 26 to automatically insert into the fixed insertion hole, and the installation rod 24 will be fixed in the installation sleeve 25, thus completing the installation operation.

[0031] like Figure 2 As shown, a guide bucket 31 is fixedly installed on the inner wall of the feed inlet 5, and the guide bucket 31 is located directly above the screen cylinder 10. By setting the guide bucket 31, the sludge can be guided to fall completely into the screen cylinder 10 for screening.

[0032] In summary: When using this utility model, sludge is fed into the feed inlet 5. Under the action of the guide bucket 31, the sludge can be guided to fall completely into the screen cylinder 10. At this time, the drive motor 3 and the control motor 21 can be started, and hot fluid is introduced into the hollow rotating shaft 4. The operation of the control motor 21 will drive the first bevel gear 22 to rotate. Due to the gear meshing principle, the rotation of the first bevel gear 22 will drive the two second bevel gears 23 meshing with it to rotate in opposite directions. This will drive the hollow rotating shaft 15 and the vertical rotating shaft 16 to rotate in opposite directions simultaneously. The rotation of the hollow rotating shaft 15 will drive the screen cylinder 10 to rotate together through the connecting plate 18 and the connecting rod 17. The rotation of the screen cylinder 10 will generate centrifugal force, which will throw smaller sludge particles out of the screen cylinder 10 through the screen holes, and then fall into the equipment casing 2 through the feed inlet 5. At the same time, the operation of the drive motor 3 will drive the drive gear 29 to rotate, and the rotation of the drive gear 29 will drive the two second bevel gears 23 meshing with it to rotate in opposite directions. One of the meshing connecting gears 30 rotates together, and the rotation of one connecting gear 30 drives the other connecting gear 30 to rotate in the opposite direction, which in turn drives the two hollow rotating shafts 4 to rotate in the opposite direction. At this time, the hollow paddle 7 rotates together with the hollow rotating shaft 4 to stir, compress and heat the sludge, thereby achieving the dewatering and drying treatment of the sludge. Larger stones and other impurities cannot pass through the screen holes and will remain in the screen cylinder 10, thus separating the sludge from the stones. This effectively avoids a series of operational problems caused by stones and other impurities being put into the equipment together. During this process, the reverse rotation of the vertical rotating shaft 16 drives the stirring shaft 11 to rotate in the opposite direction through the internal hexagon socket 19 and the hexagon plug 20. The reverse rotation of the stirring shaft 11 drives the stirring rod 12 to crush and disperse the sludge blocks, improving the dispersion of the sludge and allowing it to pass through the screen holes better, effectively improving the screening efficiency and effect.

[0033] When there are many stones and other impurities inside the screen cylinder 10 after prolonged use, the operator can open the inspection door 6 and pull the pull block 27 outwards. The outward movement of the pull block 27 will stretch and deform the return spring 28, simultaneously causing the fixing rod 26 to gradually move out of the fixing hole until it is completely disengaged. Then, the mounting rod 24 can be released, and the screen cylinder 10 can be directly removed from the inspection port. The stones and other impurities inside can then be emptied and cleaned. After cleaning, the screen cylinder 10 can be removed. Align the mounting rod 24 and insert it into the mounting sleeve 25. Align the connecting rod 17 and insert it into the connecting hole on the connecting plate 18. Align the hexagonal plug 20 and insert it into the internal hexagonal socket 19. Then release the pull block 27. At this time, under the elastic force of the reset spring 28, the pull block 27 will be pulled inward to automatically reset, which will drive the fixing rod 26 to automatically insert into the fixing hole, and fix the mounting rod 24 in the mounting sleeve 25 to complete the installation operation of the screen cylinder 10. Finally, close the maintenance door 6.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
