Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and in particular to a sludge treatment device with anti-clogging function. Background Technology

[0002] Sludge treatment is the process of reducing, stabilizing, and rendering harmless sludge. The higher the level of wastewater treatment, the more sludge residue will be generated and requires treatment. Unless land-based treatment or sewage ponds are used, most wastewater treatment plants must have sludge treatment facilities. For modern wastewater treatment plants, sludge treatment and disposal has become the most complex and costly part of the wastewater treatment system operation.

[0003] Currently, when treating sludge, the high water content and the presence of mud lumps, stones, and other particles in the sludge affect subsequent processing. Sludge transport can also easily cause blockages in the transport pipelines, impacting treatment efficiency. Existing sludge treatment devices lack filtration structures, leading to impurities in the sludge clogging the pipes and making them unusable. To address these issues, a solution is proposed below. Utility Model Content

[0004] The purpose of this invention is to provide a sludge treatment device with anti-clogging function to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A sludge treatment device with anti-clogging function includes a treatment box. A feed hopper is located at the top of the treatment box and communicates with the interior of the treatment box. An annular limiting plate is installed inside the treatment box, and the inner wall of the annular limiting plate has an inverted frustum structure. A filter plate is installed at the bottom of the annular limiting plate. A stirring and filtering assembly that cooperates with the filter plate is installed inside the treatment box. A drain bucket is installed at the bottom of the annular limiting plate, and a sludge bucket is installed inside the drain bucket. Both the drain bucket and the sludge bucket have through-hole structures at the top. Several drainage holes are provided on the outer wall of the sludge bucket. The top of the sludge bucket corresponds to the filter plate. A driving assembly for stirring and conveying sludge is provided inside the sludge bucket. A conveying assembly for conveying sludge is also provided on the inner bottom wall of the treatment box.

[0007] Preferably, the stirring and filtering assembly includes several stirring plates, a connecting rod, and a drive motor. The drive motor is fixed to the top of the processing box, and the output shaft of the drive motor passes through the top plate of the processing box. The output shaft of the drive motor is fixedly connected to the connecting rod. Each stirring plate is fixed to the bottom side wall of the connecting rod, and the stirring plate is disposed on the top of the filter plate.

[0008] Preferably, the stirring plate includes a connecting plate one and a connecting plate two. One end of the connecting plate one is fixed to the bottom side wall of the connecting rod one, and the other end of the connecting plate one is fixedly connected to the connecting plate two. The connecting plate two is fixed at an angle to the connecting plate one. The bottom of both the connecting plate one and the connecting plate two are rubber strip structures. The bottom of the connecting plate one is in contact with the filter plate, and the bottom of the connecting plate two is in contact with the inner wall of the annular limiting plate.

[0009] Preferably, the drive assembly includes a first spiral feed rod and a second spiral feed rod. A through hole is provided in the middle of the filter plate. The bottom of the first connecting rod passes through the through hole and is fixedly connected to one end of the first spiral feed rod. The other end of the first spiral feed rod is fixedly connected to the second spiral feed rod. The bottom of the sludge bucket has a conical structure, and the diameter of the sludge bucket gradually decreases. A conveying pipe is installed at the bottom of the sludge bucket, and the bottom of the conveying pipe passes through the drain bucket. An electromagnetic control valve is installed on the conveying pipe, and the bottom end of the second spiral feed rod is located inside the conveying pipe.

[0010] Preferably, the conveying assembly includes a mud discharge pipe, a screw feeder three, a connecting rod two, and a drive motor two. The mud discharge pipe is installed at the bottom of the processing box, with one end of the mud discharge pipe penetrating the processing box. A connecting groove that mates with the conveying pipe is opened at the top of the mud discharge pipe. The screw feeder three rotates within the mud discharge pipe. The drive motor two is installed on the side wall of the processing box. The connecting rod two rotates within the processing box. One end of the output shaft of the drive motor two penetrates the processing box and is fixedly connected to one end of the connecting rod two.

[0013] Preferably, a filter cloth is installed on the outer wall of the sludge bucket.

[0014] Beneficial effects: When sludge needs to be treated, the sludge can be poured into the treatment box through the feed hopper. The sludge will fall into the inside of the annular limiting plate and be filtered through the filter plate. The filter plate can remove impurities from the sludge and prevent the sludge from clogging the pipe during subsequent transportation. In order to improve the sludge filtration efficiency, the stirring filter component can be activated. The stirring filter component stirs the sludge, making the sludge flow, thereby improving the sludge filtration efficiency. The rubber strip prevents the stirring plate from damaging the filter plate.

[0015] After filtration, the sludge falls into a sludge bucket. A drainage hole on the bucket allows for simple draining, improving the efficiency of subsequent dewatering. When the sludge needs to be discharged from the treatment tank, the conveying pipe is opened, allowing the sludge to exit. During discharge, the drive motor is activated, driving the drive assembly. The drive assembly uses a spiral feeding structure to convey the sludge, preventing pipe blockage. Finally, the sludge enters the conveying assembly, where a spiral feed rod (3) further transports it to subsequent steps. The spiral feed rod (3) further enhances the anti-clogging effect.

Detailed Implementation

[0022] See Figures 1 to 5 As shown, a sludge treatment device with anti-clogging function includes a treatment box 1. The top of the treatment box 1 is provided with a feed hopper 2, which is connected to the inside of the treatment box 1. When sludge needs to be treated, the sludge can be poured into the treatment box 1 through the feed hopper 2. An annular limiting plate 3 is installed inside the treatment box 1. The inner wall of the annular limiting plate 3 is an inverted frustum structure. A filter plate 4 is installed at the bottom of the annular limiting plate 3. The sludge will fall into the inside of the annular limiting plate 3 and be filtered through the filter plate 4. The filter plate 4 can remove impurities from the sludge and prevent the sludge from clogging the pipeline during subsequent transportation.

[0023] The processing box 1 is equipped with a stirring filter assembly 5 that works in conjunction with the filter plate 4. In order to improve the filtration efficiency of sludge, the stirring filter assembly 5 can be activated to stir the sludge, thereby making the sludge flow and improving the filtration efficiency of sludge.

[0024] The stirring and filtering assembly 5 includes several stirring plates 51, a connecting rod 52, and a drive motor 53. The drive motor is fixed to the top of the processing box 1. The output shaft of the drive motor 53 passes through the top plate of the processing box 1 and is fixedly connected to the connecting rod 52. Each stirring plate 51 is fixed to the bottom side wall of the connecting rod 52. The stirring plates 51 are set on the top of the filter plate 4. When it is necessary to stir the sludge, the drive motor 53 can be started. The drive motor 53 drives the connecting rod 52 to rotate, which in turn drives the stirring plates 51 to rotate. The stirring plates 51 then push the sludge to flow. The sludge can be filtered better during the flow process, and it also prevents the filtered impurities from clogging the filter plate 4 when they are stationary.

[0025] The stirring plate 51 includes a first connecting plate 511 and a second connecting plate 512. One end of the first connecting plate 511 is fixed to the bottom side wall of the first connecting rod 52, and the other end of the first connecting plate 511 is fixedly connected to the second connecting plate 512. The second connecting plate 512 is fixed to the first connecting plate 511 at an angle. The bottom of both the first connecting plate 511 and the second connecting plate 512 are rubber strip structures. The bottom of the first connecting plate 511 contacts the filter plate 4, and the bottom of the second connecting plate 512 contacts the inner wall of the annular limiting plate 3. When the first connecting rod 52 rotates, it will first drive the connecting plate 512 to rotate. The first plate 511 rotates, stirring the filter plate 4 via the first connecting plate 511. The first connecting plate 511 drives the second connecting plate 512 to rotate, scraping the inner wall of the annular limiting plate 3, preventing sludge from adhering to the annular limiting plate 3. The rubber strip structure at the bottom of the first connecting plate 511 and the second connecting plate 512 provides a flexible connection between the filter plate 4 and the annular limiting plate 3, preventing damage to the filter plate 4 and the annular limiting plate 3. This rubber strip has moderate hardness, good wear resistance, and corrosion resistance. This flexible connection method ensures effective contact between the stirring plate 51 and the filter plate 4 and the annular limiting plate 3 during rotation, while preventing hard damage to both. Specifically, when the drive motor 53 is started, its output shaft drives the connecting rod 52 to rotate at a constant speed, thereby causing the stirring plate 51 to rotate around the axis. At this time, the rubber strip at the bottom of connecting plate 511 adheres to the surface of filter plate 4 under certain pressure. As connecting plate 511 rotates, it not only promotes the sludge to flow evenly on filter plate 4, making it easier to separate water and impurities in the sludge and effectively improving filtration efficiency, but also prevents the filtered impurities from accumulating statically on filter plate 4 and causing blockage. At the same time, the rotation of connecting plate 511 will drive connecting plate 512 to move synchronously. The rubber strip at the bottom of connecting plate 512 is in close contact with the inner wall of the annular limiting plate 3, scraping off any sludge that may be attached to the inner wall, keeping the inner surface of the annular limiting plate 3 clean, and ensuring that the sludge can flow smoothly to filter plate 4 for filtration.

[0026] A drain bucket 6 is installed at the bottom of the annular limiting plate 3. A sludge bucket 7 is installed inside the drain bucket 6. Both the drain bucket 6 and the sludge bucket 7 have through-hole structures at the top. Several drainage holes are opened on the outer wall of the sludge bucket 7. The top of the sludge bucket 7 corresponds to the filter plate 4. The filtered sludge will fall into the sludge bucket 7. The sludge can be simply drained through the drainage holes on the sludge bucket 7, which can improve the efficiency of subsequent sludge dewatering treatment. A filter cloth 13 is installed on the outer wall of the sludge bucket 7. The filter cloth 13 can block the drainage holes to prevent sludge from flowing out of the sludge bucket 7 from the drainage holes. A second drainage hole is opened on the bottom side wall of the drain bucket 6. A drain pipe 10 is installed on the second drainage hole. One end of the drain pipe 10 passes through the treatment box 1. The sewage flowing out of the sludge bucket 7 can flow into the drain pipe 10 through the second drainage hole on the drain bucket 6 and then be discharged from the treatment box 1 through the drain pipe 10.

[0027] The sludge tank 7 is equipped with a drive component 8 for stirring and conveying sludge. After the sludge enters the sludge tank 7, it is stirred by the drive component 8. Stirring the sludge by the drive component 8 can increase the contact area between the sludge and water, break the surface tension of the water, and help the water to detach from the sludge surface more quickly.

[0028] The drive assembly 8 includes a first screw feeder 81 and a second screw feeder 82. A through hole is provided in the middle of the filter plate 4. The bottom of the first connecting rod 52 passes through the through hole and is fixedly connected to one end of the first screw feeder 81. The other end of the first screw feeder 81 is fixedly connected to the second screw feeder 82. The first connecting rod 52 drives the first connecting plate 511 to rotate while also driving the first screw feeder 81 to rotate. The first screw feeder 81 drives the second screw feeder 82 to rotate. The bottom of the sludge bucket 7 has a conical structure, and the diameter of the sludge bucket 7 decreases from large to small. The size of the first screw feeder 81 is larger than that of the second screw feeder 82. The first screw feeder 81 is adapted to the upper end of the sludge bucket 7, and the second screw feeder 82 is adapted to the conical bottom of the sludge bucket 7, thereby ensuring the spiral stirring of the sludge.

[0029] A conveying pipe 83 is installed at the bottom of the sludge bucket 7, and the bottom of the conveying pipe 83 passes through the drain bucket 6. An electromagnetic control valve is installed on the conveying pipe 83. The bottom end of the screw feeder 82 is located inside the conveying pipe 83. After all the sludge has been filtered and entered the sludge bucket 7, the electromagnetic control valve can be opened. After the electromagnetic control valve is opened, the sludge can enter the conveying pipe 83 for conveying. During the sludge conveying process, the drive motor 53 can be reversed via an external controller. When the sludge is being filtered and entering the sludge bucket 7, the drive motor 53... When the drive motor 53 rotates forward, the connecting rod 52 will drive the screw feed rod 81 to rotate forward. The screw feed rod 81 lifts the sludge when rotating forward. When the drive motor 53 rotates in reverse, the screw feed rod 81 will rotate in reverse. At this time, the screw feed rod 81 will convey the sludge downward. The screw feed rod 82 will convey the sludge into the conveying pipe 83. The screw feed rod 82 prevents the sludge from flowing too slowly at the opening of the conveying pipe 83 and causing blockage.

[0030] The inner bottom wall of the treatment box 1 is also equipped with a conveying assembly 9 for conveying sludge. The sludge will eventually enter the conveying assembly 9 through the conveying pipe 83. The sludge will be conveyed to subsequent steps by the spiral feed rod 92 inside the conveying assembly 9. The spiral feed rod 92 further enhances the anti-clogging effect. The conveying assembly 9 includes a sludge discharge pipe 91, a spiral feed rod 92, a connecting rod 93, and a drive motor 94. The sludge discharge pipe 91 is installed at the bottom of the treatment box 1, with one end of the sludge discharge pipe 91 penetrating through the treatment box 1. The top of the sludge discharge pipe 91 has a connecting groove that mates with the conveying pipe 83. The rotation of the spiral feed rod 92 is located inside the sludge discharge pipe 91. The drive motor 94... The second motor 94 is installed on the side wall of the treatment box 1. The second connecting rod 93 is rotatably set inside the treatment box 1. One end of the output shaft of the second motor 94 passes through the treatment box 1 and is fixedly connected to one end of the second connecting rod 93. The other end of the second connecting rod 93 passes through the sludge discharge pipe 91 and is fixedly connected to the third screw feeder 92. When the sludge enters the sludge discharge pipe 91 through the conveying pipe 83, the second motor 94 will start. The output shaft of the second motor 94 will drive the second connecting rod 93 to rotate. The second connecting rod 93 will drive the third screw feeder 92 in the sludge discharge pipe 91 to convey the sludge. The sludge entering the sludge discharge pipe 91 can be conveyed outward through the third screw feeder 92.

[0031] The processing box 1 includes a box body 11 and a box cover 12. A drive motor 53 is installed on the top of the box cover 12. The box body 11 and the box cover 12 are fixedly connected by several latches. Through the design of the box body 11 and the box cover 12, the top of the processing box 1 can be disassembled, and the filter plate 4 can be removed from the annular limiting plate 3 and taken out of the box body 11 together with the connecting rod 52, which facilitates the cleaning of the box body 11.

[0032] Working principle: When sludge needs to be treated, the sludge can be poured into the treatment box 1 through the feed hopper 2. The sludge will fall into the interior of the annular limiting plate 3 and be filtered through the filter plate 4. During the filtration process, the stirring filter assembly 5 can be activated to stir the sludge. The stirring filter assembly 5 is connected to the first connecting plate 511 and the second connecting plate 512 to realize the rotation of the filter plate 4 and the annular limiting plate 3, so that the sludge flows, thereby improving the sludge filtration efficiency.

[0033] After filtration, the sludge falls into the sludge bucket 7. A drainage hole 1 on the sludge bucket 7 allows for simple drainage, improving the efficiency of subsequent dewatering. When the sludge needs to be discharged from the treatment box 1 after processing, the conveying pipe 83 is opened, allowing the sludge to be discharged. During discharge, the drive motor 53 is activated, driving the drive assembly 8. The drive assembly 8 uses a spiral feeding structure to convey the sludge, preventing pipe blockage. Finally, the sludge enters the conveying assembly 9, where a spiral feeding rod 92 inside the assembly further transports it to subsequent steps. The spiral feeding rod 92 further prevents blockage.
