Description

Technical Field

[0001] This utility model relates to the technical field of environmental wastewater treatment equipment, specifically to a sludge dewatering device with automatic sludge discharge function. Background Technology

[0002] In the field of environmental wastewater treatment, sludge dewatering is the core step in achieving sludge reduction. It is widely used in municipal sewage, industrial wastewater treatment, as well as in the treatment of solid waste sludge such as river dredging and livestock manure.

[0003] However, in actual operation, the sludge dewatering equipment currently relies heavily on manual intervention for its sludge discharge mechanism. Most require manual intervention to periodically open the discharge port to clean the dewatered sludge residue, which not only increases labor costs but also limits sludge treatment efficiency due to the intermittent nature of manual operation. Although some equipment has a simple sludge discharge structure, manual assistance is still required to reset or clean residual residue, making fully automated sludge discharge impossible. Furthermore, manual contact with sludge can easily cause secondary pollution, which not only fails to comply with environmental protection operation standards but also increases the health risks to operators. On the other hand, existing equipment lacks a targeted cleaning design. After sludge is squeezed and dewatered, it is easy for residues to remain and clump together. Long-term accumulation can cause filter pore blockage and obstruction of the sludge discharge channel, requiring frequent shutdowns for disassembly and cleaning. This not only increases the frequency of equipment maintenance but also interrupts the dewatering and sludge discharge process, seriously affecting the overall treatment efficiency and making it difficult to meet the continuous and stable sludge treatment needs.

[0004] Therefore, there is an urgent need for a sludge dewatering equipment that can achieve fully automatic sludge discharge to reduce manual intervention and secondary pollution, and integrate dewatering, sludge discharge and cleaning functions to ensure continuous and stable operation. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sludge dewatering device with an automatic sludge discharge function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sludge dewatering device with automatic sludge discharge function, comprising an installation box, a transmission component installed inside the installation box for conveying and compressing sludge, one side of the installation box connected to one end of a compression cylinder, a drainage box disposed on the outer side of the compression cylinder away from the installation box for holding wastewater, a drain outlet disposed on the lower surface of the drainage box for discharging wastewater, a sealing plate bolted to the end of the drainage box away from the installation box, a sludge discharge component disposed at the end of the compression cylinder away from the installation box for discharging sludge, and a cleaning component disposed above the interior of the drainage box for tilting the interior.

[0007] As a further description of the above technical solution:

[0008] The upper surface of the extrusion cylinder is connected to the lower end of the hopper on the side near the mounting box. The hopper is used for the entry of sludge. The middle of the side of the sealing plate away from the drainage box is connected to one end of the guide channel. The guide channel is used for the discharge of sludge.

[0009] As a further description of the above technical solution:

[0010] The transmission assembly includes a motor, which is placed inside the mounting box, and the output shaft of the motor is connected to a drive gear. The drive gear meshes with a driven gear, and the driven gear is connected to the outer wall of the rotating disk by bolts.

[0011] As a further description of the above technical solution:

[0012] The rotating disk is rotatably connected to one end of the extrusion cylinder near the mounting box, and the side of the rotating disk away from the mounting box is connected to one end of the conical blade, which is placed inside the extrusion cylinder.

[0013] As a further description of the above technical solution:

[0014] The cleaning assembly includes a water inlet located on the outside of the sealing plate, with the lower end of the water inlet connected to the middle of the upper surface of the diversion pipe. The two ends of the diversion pipe are connected to one end of the delivery pipe, and the other end of the delivery pipe extends into the interior of the drain tank. Multiple inclined nozzles are provided on the opposite side of the delivery pipe.

[0015] As a further description of the above technical solution:

[0016] The slag discharge assembly includes a support plate, the upper end of which is connected to the inner wall of the end of the extrusion cylinder, and the lower end of which is hinged to the upper end of the movable plate. A torsion spring is provided at the hinge point between the support plate and the movable plate.

[0017] As a further description of the above technical solution:

[0018] A baffle is provided on the side of the support plate near the extrusion cylinder. The baffle is used to prevent sludge from entering the hinge between the support plate and the movable plate.

[0019] This utility model has the following beneficial effects:

[0020] 1. Through the cooperation of the support plate, hinged movable plate and torsion spring in the sludge discharge assembly, when the sludge is squeezed to the end of the extrusion cylinder, the movable plate can be automatically pushed to open and discharge the sludge. The torsion spring drives the movable plate to reset synchronously. There is no need for manual cleaning of sludge, which reduces the manual intervention and improves the sludge treatment efficiency, while avoiding the risk of secondary pollution caused by manual contact with sludge.

[0021] 2. The equipment uses conical blades to extrude sludge for dewatering and a drainage tank to collect and discharge wastewater. At the same time, the cleaning components can use the inlet, diversion pipe and inclined nozzle to clean the inside of the equipment, effectively removing sludge residue from the inner wall of the extrusion cylinder and the sludge discharge components, preventing sludge from clumping and clogging the filter holes or hinges, extending the service life of the equipment's vulnerable parts, and ensuring continuous and uninterrupted dewatering and sludge discharge operations.

[0031] Example 1:

[0032] like Figures 1 to 4 As shown, the sludge dewatering equipment with automatic sludge discharge function provided in this embodiment includes an installation box 1. A transmission component 4 is installed inside the installation box 1. The transmission component 4 is used for conveying and compressing sludge. One side of the installation box 1 is connected to one end of a compression cylinder 3. A drainage box 2 is provided on the outer side of the compression cylinder 3 away from the installation box 1. The drainage box 2 is used for holding wastewater. A drain outlet 10 is provided on the lower surface of the drainage box 2. The drain outlet 10 is used for discharging wastewater. A sealing plate 8 is bolted to the end of the drainage box 2 away from the installation box 1. A sludge discharge component 6 is provided at the end of the compression cylinder 3 away from the installation box 1. The sludge discharge component 6 is used for discharging sludge. A cleaning component 5 is provided on the upper part of the interior of the drainage box 2. The cleaning component 5 is used for internal tilting.

[0033] In this embodiment, the transmission component 4, the cleaning component 5, and the sludge discharge component 6 constitute the sludge dewatering equipment with automatic sludge discharge function involved in this application.

[0034] It should also be noted that the sludge dewatering in this application can be used for municipal sewage sludge dewatering, industrial wastewater sludge dewatering, river dredging sludge dewatering, etc. Figure 1 In this embodiment, municipal sewage sludge dewatering is used as an example for description. Of course, other types of sludge dewatering can also adopt a similar structure, which will not be described in detail below.

[0035] Understandable, Figure 1 The diagram only schematically illustrates some of the components included in the slag discharge and dewatering equipment. The actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, slag discharge and dewatering equipment can also include, compared to... Figure 1 More or fewer parts.

[0036] In addition, a fluororubber sealing ring is fitted at the contact point between the drainage tank 2 and the squeezing cylinder 3 to prevent sewage from seeping out of the drainage tank and improve the overall sealing of the equipment. The upper end of the column is connected to the lower surface of the mounting box 1 and the drainage tank 2. The outer wall of the squeezing cylinder 3 near the drainage tank 2 is provided with small filter holes. The operation of the transmission component 4 realizes the conveying and squeezing of sludge in the squeezing cylinder 3. The sewage generated by the sludge squeezing flows into the drainage tank 2 and is discharged through the drain outlet 10. The sludge discharge component 6 discharges the dewatered sludge, and the cleaning component 5 cleans the inside of the equipment, realizing the integrated operation of sludge dewatering, sewage collection, automatic sludge discharge, and internal cleaning, which meets the basic sludge treatment process requirements.

[0037] Specifically, the upper surface of the extrusion cylinder 3 is connected to the lower end of the hopper 7 on the side near the mounting box 1. The hopper 7 is used for the entry of sludge. The middle of the side of the sealing plate 8 away from the drainage box 2 is connected to one end of the guide channel 9. The guide channel 9 is used for the discharge of sludge.

[0038] In this embodiment, sludge enters the extrusion cylinder 3 through the hopper 7, and after dewatering, the sludge is discharged through the slag discharge assembly 6 and then guided to the external collection device through the guide channel 9, thus constructing a smooth channel for sludge to enter and exit, avoiding leakage of sludge during the feeding and discharging process, and ensuring a clean working environment.

[0039] Example 2:

[0040] A transmission component 4 is provided based on embodiment 1.

[0041] Specifically, the transmission assembly 4 includes a motor 401, which is placed inside the mounting box 1. The output shaft of the motor 401 is connected to a drive gear 402, which meshes with a driven gear 403. The driven gear 403 is connected to the outer wall of the rotating disk 404 by bolts.

[0042] As a preferred implementation, the motor 401 starts and drives the drive gear 402 to rotate, the drive gear 402 drives the meshing driven gear 403 to rotate, and the driven gear 403 drives the rotating disk 404 to rotate synchronously, providing a stable power transmission and laying the power foundation for subsequent sludge conveying and compression. It has high transmission efficiency and low failure rate.

[0043] Specifically, the rotating disk 404 is rotatably connected to one end of the extrusion cylinder 3 near the mounting box 1, and the side of the rotating disk 404 away from the mounting box 1 is connected to one end of the conical blade 405, which is placed inside the extrusion cylinder 3.

[0044] In this embodiment, polytetrafluoroethylene sealing filler is embedded in the rotating connection between the rotating disk 404 and the extrusion cylinder 3 to prevent sludge from entering the rotating gap of the rotating disk and causing jamming, contaminating the gear transmission structure, and extending the service life of the transmission components. The rotating disk 404 drives the conical blade 405 to rotate, and the conical blade 405 pushes the sludge to the right along the extrusion cylinder 3. At the same time, the gradual change in diameter exerts a squeezing effect on the sludge, realizing the simultaneous conveying and extrusion dewatering of the sludge, improving the sludge dewatering rate, and ensuring that the sludge moisture is fully separated.

[0045] Specifically, the cleaning assembly 5 includes a water inlet 501, which is located on the outside of the sealing plate 8. The lower end of the water inlet 501 is connected to the middle position of the upper surface of the diversion pipe 502. Both ends of the diversion pipe 502 are connected to one end of the conveying pipe 503. The other end of the conveying pipe 503 extends into the interior of the drain tank 2. Multiple inclined nozzles 504 are provided on the opposite side of the conveying pipe 503.

[0046] With this setup, water enters from the inlet 501, is diverted through the diversion pipe 502 to two delivery pipes 503, and then sprayed out through the nozzle 504 to the inside of the drain tank 2 and the outside of the squeezing cylinder 3, specifically cleaning areas where sludge is prone to remain, preventing sludge from accumulating and clogging filter holes or equipment parts, and maintaining the cleanliness of the equipment.

[0047] Example 3:

[0048] A slag discharge component 6 is provided based on embodiment 2.

[0049] Specifically, the slag discharge assembly 6 includes a support plate 601, the upper end of which is connected to the inner wall of the end of the extrusion cylinder 3, and the lower end of the support plate 601 is hinged to the upper end of the movable plate 602. A torsion spring 603 is provided at the hinge point between the support plate 601 and the movable plate 602.

[0050] In this design, a nitrile rubber sealing gasket is attached to the contact surface between the movable plate 602 and the inner wall of the extrusion cylinder 3 to prevent undehydrated sludge from leaking prematurely from the gap between the movable plate and the extrusion cylinder, ensuring that the sludge is fully dehydrated in the extrusion cylinder. When the sludge is squeezed to the right end of the extrusion cylinder 3, it generates a thrust on the movable plate 602, causing the movable plate 602 to rotate around the hinge shaft and compress the torsion spring 603. After the sludge is discharged, the torsion spring 603 rebounds and drives the movable plate 602 to reset and close, realizing automatic sludge discharge without the need for manual operation to reset, reducing manual intervention and improving work efficiency.

[0051] Specifically, a baffle 604 is provided on the side of the support plate 601 near the extrusion cylinder 3. The baffle 604 is used to prevent sludge from entering the hinge between the support plate 601 and the movable plate 602.

[0052] In this embodiment, during the sludge compression and movement process, the baffle 604 prevents the sludge from entering the hinge gap between the support plate 601 and the movable plate 602, thus avoiding the sludge getting stuck at the hinge part, ensuring the rotational flexibility of the movable plate 602, and preventing the sludge discharge assembly 6 from malfunctioning.

[0053] In actual use, the device is first securely placed using the uprights. Then, sludge is poured into the extrusion cylinder 3 through the hopper 7. Simultaneously, the motor 401 is started. The output shaft of the motor 401 drives the drive gear 402 to rotate. Since the drive gear 402 meshes with the driven gear 403, the rotation of the drive gear 402 drives the driven gear 403 to rotate. The rotation of the driven gear 403 drives the rotating disk 404 to rotate, which in turn drives the conical blades 405 to rotate. The rotation of the conical blades 405 moves the sludge. Because the conical blades 405 are conical with decreasing size, the sludge is squeezed while moving. At this time, the wastewater in the sludge is discharged through the filter holes on the outer wall of the extrusion cylinder 3. After being discharged, the wastewater flows into the drainage tank 2. Finally, the drain outlet 10 is opened, and the sewage flows out through the drain outlet 10. The sludge continues to be squeezed to the smallest end of the squeezing cylinder 3. At this time, due to the accumulation of sludge, the sludge pushes the movable plate 602. The movable plate 602 rotates along the hinge between the movable plate 602 and the support plate 601 and squeezes the torsion spring 603. Then the sludge flows out through the opening of the movable plate 602 and enters the external collection device through the guide channel 9. After the pressure of the sludge decreases, the torsion spring 603 pushes the movable plate 602 to rotate and reset. After the sludge is dewatered, the water inlet 501 is opened. At this time, the water source enters the diversion pipe 502 through the water inlet 501, and enters the conveying pipe 503 through the diversion pipe 502. Then it is sprayed out through the nozzle 504, thereby cleaning the inside of the device.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
