Description

Technical Field

[0001] This utility model relates to the field of sludge feeding anti-clogging technology, specifically a belt filter press sludge feeding anti-clogging urban sludge treatment device. Background Technology

[0002] With the acceleration of urbanization, the volume of urban sewage treatment has surged, and the resulting sludge (80%-90% moisture content) needs to be dewatered before subsequent disposal (such as landfill, incineration, or resource utilization). Belt filter presses have become the mainstream equipment for urban sludge dewatering due to their large processing capacity, high dewatering efficiency, and low operating costs. However, the feeding process has strict requirements on the sludge state, requiring it to be loose and uniform, avoiding large impurities, clumps, or local accumulation. Otherwise, it can easily lead to problems such as feed inlet blockage, conveyor belt deviation, and uneven filtration, seriously affecting processing efficiency. Therefore, the core requirements of the belt filter press feeding device are concentrated in four aspects: first, clump breaking, thoroughly breaking up large clumps in the sludge; second, impurity interception, filtering hard impurities in the sludge; third, uniform conveying, ensuring that the sludge is evenly spread into the filter press; and fourth, anti-sticking and anti-clogging, preventing sludge from adhering and remaining in the conveying path.

[0003] Currently, the existing sludge feeding devices for belt filter presses in the industry mainly adopt the traditional technical solution of a single conveying pipe and simple agitation. Specifically, sludge is directly pumped from the sludge storage tank to the belt filter press inlet via a centrifugal pump. Some devices add a single-shaft agitator at the front end of the feed pipe, which can only perform simple agitation of the sludge. There is no dedicated structure for pulverizing clumps or filtering impurities. The feeding method is direct impact, and sludge easily accumulates at the inlet. The traditional single-shaft agitator can only break up loose surface clumps, but cannot break up the core hard clumps. After the hard clumps enter the inlet with the sludge, they are easily stuck in the gap between the conveyor belt and the feed hopper, causing feed blockage. On average, the machine needs to be stopped for cleaning every 2-3 hours, and each cleaning takes 30-60 minutes. The equipment utilization rate is only 60%-70%. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a clog-resistant urban sludge treatment device for belt filter press sludge feeding. It solves the problem of traditional belt filter press sludge feeding devices primarily using a single conveying pipe and simple agitation. Specifically, these devices pump sludge directly from the storage tank to the belt filter press inlet using a centrifugal pump. Some devices add a single-shaft agitator at the front end of the feed pipe, which only provides simple agitation of the sludge, lacking dedicated agglomeration crushing and impurity filtration structures. The feeding method is direct impact, leading to sludge accumulation at the inlet. Traditional single-shaft agitators can only break up loose surface agglomerates, failing to remove core hardened clumps. These hardened clumps, after entering the inlet with the sludge, easily become stuck in the gap between the conveyor belt and the feed hopper, causing blockages. On average, the machine needs to be stopped for cleaning every 2-3 hours, with each cleaning taking 30-60 minutes, resulting in an equipment uptime of only 60%-70%.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figure 1-5This utility model provides a new technical solution: a belt filter press sludge feeding anti-clogging type urban sludge treatment device, including a belt filter press 1: the belt filter press 1 is the core equipment for urban sludge treatment. A conveyor box 3 is fixedly connected to the upper surface of the belt filter press 1. The lower end of the discharge box 4 extends from the inlet of the belt filter press 1. The belt filter press 1 receives the sludge treated with anti-clogging through the inlet and performs filtration and dewatering operations. It is the terminal equipment for sludge treatment. The anti-clogging feeding component provides it with loose and uniform sludge raw materials to ensure filtration efficiency and effect.

[0038] Conveying box 3: Multiple transverse moving plates 10 slide through the right side of conveying box 3. A discharge box 4 is fixedly connected to the front side of the lower surface of conveying box 3. Conveying box 3 is the transfer space for sludge pretreatment and conveying, carrying combing and conveying components, and uniformly guiding the crushed sludge to belt filter press 1. It is the core transition carrier for anti-clogging feeding.

[0039] Cylinder 11: Cylinder 11 is the driving source of the transverse moving plate 10. Through the reciprocating left and right movement of the telescopic end, it drives the fixed plate 2 and the transverse moving plate 10 to move synchronously, providing power for the combing teeth 19 to break up the sludge.

[0040] Fixed plate 2: Fixed plate 2 connects multiple transverse moving plates 10 into a whole, ensuring that the driving force of cylinder 11 can be synchronously transmitted to all transverse moving plates, so as to achieve coordinated and consistent combing action.

[0041] Lateral moving plate 10: The lateral moving plate 10 moves back and forth under the drive of cylinder 11, driving the combing teeth 19 to comb the sludge on the conveyor belt. It is the direct transmission component for breaking up small clumps and spreading the sludge.

[0042] Combing teeth 19: Combing teeth 19 slide left and right with the transverse moving plate 10, directly inserting into the sludge on the conveyor belt of the conveying mechanism 21, breaking up residual small clumps and combing the sludge layer to make its thickness uniform, avoiding local accumulation that could lead to subsequent blockage.

[0043] Conveying mechanism 21: There is a certain gap between the front end of the conveying mechanism 21 and the inner wall of the front side of the conveying box 3. The conveying mechanism 21 is the conveying carrier of sludge in the conveying box 3, which drives the pre-treated loose sludge to move from back to front, providing a carrier for the combing teeth 19, and at the same time conveying the sludge to the inclined plate 20.

[0044] Conveying tank 6: The lower end of the discharge pipe of the inclined conical tank 8 runs through the interior of the conveying tank 6. The conveying tank 6 is the core space for secondary sludge crushing. Through the cooperation of the spiral conveyor and the hexagonal prism, the sludge conveyed by the inclined conical tank 8 is further crushed to ensure that the sludge entering the conveying box 3 is loose.

[0045] First drive motor 5: The first drive motor 5 is the power source for sludge conveying and crushing in the conveying tank 6. It drives the connecting shaft 16 and the spiral conveying blades 17 to rotate through the output end, providing power for sludge movement and secondary crushing.

[0046] Connecting shaft 16: Connecting shaft 16 transmits the rotational power of the first drive motor 5, drives the spiral conveying blades 17 to rotate, and pushes the sludge in the conveying tank 6 to move towards the rear discharge pipe.

[0047] Spiral conveyor blade 17: The spiral conveyor blade 17 rotates with the connecting shaft 16, pushing the sludge in the conveying tank 6 to move in a direction. At the same time, it cooperates with the hexagonal crushing column 18 to shear and rub the sludge clumps to achieve secondary crushing.

[0048] Hexagonal crushing column 18: Multiple hexagonal crushing columns 18 are fixedly connected to the inner wall of the conveying tank 6. The hexagonal crushing column 18 forms a shear gap with the spiral conveying blade 17 through the edge structure. When the sludge moves with the spiral blade, the clump of sludge collides and rubs with the hexagonal column and is crushed into a loose state, eliminating the risk of blockage.

[0049] Support frame 7: Support frame 7 provides lifting support for the inclined conical tank 8, fixing it at a suitable angle above the conveying tank 6 to ensure that the sludge inside the tank can flow smoothly into the conveying tank 6 under the force of gravity and the push of the spiral blades 15.

[0050] Inclined conical tank 8: The upper surface of the inclined conical tank 8 is fixedly connected to a sludge feed pipe that communicates with its interior. The inclined conical tank 8 is a container for primary sludge pretreatment. Through its inclined structure and internal stirring components, it performs preliminary dispersing and directional conveying of the incoming municipal sludge.

[0051] Second drive motor 9: The second drive motor 9 is the power source for stirring and pushing sludge in the inclined conical tank 8. It drives the drive shaft 14 and stirring and pushing components to rotate through the output end, providing power for the primary pretreatment of sludge.

[0052] Drive shaft 14: Drive shaft 14 transmits the rotational power of the second drive motor 9, which drives the arc-shaped prism plate 12 to stir the sludge and the spiral blade 15 to push the sludge to achieve primary pretreatment.

[0053] Fixed sleeve 13: Fixed sleeve 13 fixes the arc-shaped prism plate 12 on the drive shaft 14, ensuring that the arc-shaped prism plate rotates synchronously with the drive shaft, and the mixing range is expanded by the distribution of multiple fixed sleeves.

[0054] Arc-shaped prism plate 12: The arc-shaped prism plate 12 rotates with the drive shaft 14 to stir and cut the sludge in the inclined conical tank 8, break up large pieces of sludge, prevent clumps from accumulating, and the arc-shaped structure reduces sludge adhesion and ensures smooth stirring.

[0055] Spiral blade 15: pushes the sludge in the conical area of ​​the inclined conical tank 8 towards the front discharge pipe, avoiding sludge stagnation and blockage in the narrow conical area, and ensuring that the sludge continuously flows into the conveying tank 6.

[0056] Inclined plate 20: On the one hand, the inclined plate 20 scrapes off the sludge adhering to the conveyor belt of the conveying mechanism 21 to avoid waste. On the other hand, through its forward-inclined structure, it assists the sludge to slide into the discharge box 4, so as to achieve a residue-free transition of sludge from the conveyor belt to the discharge box.

[0057] Discharge box 4: The discharge box 4 collects the loose and uniform sludge processed by the conveyor box 3 and accurately introduces it into the feed port of the belt filter press 1. It is the final transition component for sludge to enter the filter press, ensuring smooth feeding without clogging.

[0058] Furthermore, when using this belt filter press sludge feeding anti-clogging type urban sludge treatment device, the conveying mechanism 21 runs from back to front. Through the coordinated action of multiple anti-clogging structures, the smooth conveying and pretreatment of sludge feeding is achieved. First, the urban sludge is injected into the tank through the sludge feed pipe on the upper surface of the inclined conical tank 8. The second drive motor 9 is started. The second drive motor 9 drives the drive shaft 14 and multiple fixed sleeves 13, arc-shaped ribs 12 and spiral blades 15 on the outer wall to rotate. The four cross-shaped arc-shaped ribs 12 stir and disperse the sludge in the tank to prevent sludge from accumulating. The spiral blades 15 located at the conical part of the inclined conical tank 8 rotate synchronously, pushing the sludge to move towards the discharge pipe at the conical end, avoiding sludge stagnation and blockage in the conical area. The pretreated sludge flows into the conveying tank 6 below through the discharge pipe.

[0059] The first drive motor 5 on the front surface of the conveying tank 6 is started, and its output end drives the connecting shaft 16 and the spiral conveying blades 17 on the outer wall to rotate. The spiral conveying blades 17 push the sludge in the tank to move to the discharge pipe on the rear side. During the movement, the sludge collides and rubs with multiple hexagonal crushing columns 18 on the inner wall of the conveying tank 6. The gap between the hexagonal crushing columns 18 and the spiral conveying blades 17 performs secondary crushing on the sludge clumps that are not completely broken up, ensuring that the sludge entering the conveying box 3 is in a loose state, further eliminating the risk of blockage. The crushed sludge falls into the conveying mechanism 21 conveyor belt inside the conveying box 3 through the discharge pipe on the lower surface of the conveying tank 6.

[0060] Among them, two cylinders 11 are started, and their extension ends drive the fixed plate 2 and multiple transverse moving plates 10 to move back and forth. Multiple combing teeth 19 on the lower surface of the transverse moving plate 10 located inside the conveying box 3 slide left and right simultaneously to comb and spread the sludge on the conveyor belt of the conveying mechanism 21, so that the sludge thickness is uniform and to avoid local accumulation that affects the subsequent filter pressing effect. At the same time, it breaks up any small clumps that may remain.

[0061] Among them, the start conveyor mechanism 21 is activated, and its conveyor belt drives the loose and uniform sludge to move from back to front. When the sludge moves to the front of the conveyor box 3, the inclined plate 20 inside the conveyor box 3 scrapes off the sludge adhering to the conveyor belt. At the same time, its forward inclined structure assists the sludge to slide into the discharge box 4 on the front side of the lower surface of the conveyor box 3. After the sludge is collected by the discharge box 4, it falls precisely into the feed port of the belt filter press 1 to complete the anti-clogging feeding process.

[0062] In this system, by setting up an anti-clogging feeding component, during the sludge feeding process, through the coordinated action of various components, the drive shaft 14 in the inclined conical tank 8 drives the arc-shaped prism plate 12 to stir and disperse the sludge, and the spiral blades 15 push the sludge. The first drive motor 5 in the conveying tank 6 drives the spiral conveying blades 17 to convey the sludge. In conjunction with the hexagonal crushing column 18, the sludge is crushed and agglomerated for a second time. The cylinder 11 in the conveying box 3 drives the transverse moving plate 10 and the combing teeth 19 to comb and spread the sludge. The conveying mechanism 21 drives the sludge to be conveyed from back to front. The inclined plate 20 scrapes off the material adhering to the conveyor belt and guides it to the discharge box 4. This achieves the comprehensive effect of three-stage anti-clogging pretreatment and loose and uniform conveying of sludge. Compared with traditional sludge feeding devices that are prone to agglomeration and clogging, this system can accurately adapt to the feeding requirements of the belt filter press 1, ensuring that the sludge enters the filter press in a loose state and smoothly, avoiding clogging of the feed inlet or affecting the filter press efficiency due to sludge accumulation, and improving the smoothness and overall efficiency of urban sludge treatment.

[0063] Example 1: Application of Rhomboid Columns Replacing Hexagonal Crusher Columns 18 in High-Viscosity Sludge Treatment Scenarios

[0064] When a wastewater treatment plant treats highly viscous urban sludge, the sludge has a high water content and strong viscosity, and is prone to re-agglomeration after stirring. Although the original hexagonal crushing column 18 can break up some of the clumps, the number of edges is limited, and the collision and friction with the spiral conveying blade 17 is not sufficient. Some viscous clumps are still not completely broken up. After these residual clumps enter the conveying box 3 with the sludge, they are easy to adhere to the combing teeth 19 or the conveying mechanism 21, resulting in local accumulation, affecting the smoothness of feeding, and making it difficult to meet the continuous treatment requirements of highly viscous sludge. At this time, the original hexagonal crushing column 18 is replaced with a rhomboid column. The rhomboid column has more edges than the hexagonal column, and the installation position is the same as the original hexagonal crushing column, maintaining an appropriate gap with the spiral conveying blade 17.

[0065] The rhomboid column, with its multiple sharp edges, creates a denser collision and friction with the rotating spiral conveyor blades 17, which can more thoroughly tear apart the agglomerated structure of highly viscous sludge. Compared with the original hexagonal crushing column 18, it has a more thorough effect on breaking up viscous clumps, leaving no obvious residual clumps in the sludge and reducing the risk of subsequent blockages from the source.

[0066] The diamond-shaped column structure does not hinder the axial flow of sludge driven by the spiral conveying blades 17. The multi-faceted design enhances the dispersing effect without increasing the sludge conveying resistance. It works smoothly in coordination with the first drive motor 5 and the connecting shaft 16, ensuring that the sludge is deeply crushed synchronously during the conveying process. The sludge entering the conveying box 3 is in a loose state, which makes it easier for the combing teeth 19 to further spread it out.

[0067] The installation dimensions of the rhomboid column are exactly the same as the original hexagonal crushing column 18. There is no need to modify the inner wall structure of the conveying tank 6. It can be used directly as a replacement. Its material is the same as the original crushing column. It is wear-resistant and corrosion-resistant, and is suitable for the long-term treatment needs of high-viscosity sludge. There is no additional modification cost.

[0068] Example 2: Application of a serrated arc-shaped plate replacing the arc-shaped prism plate 12 in a sludge treatment scenario containing hard, solid sludge.

[0069] The sludge produced from the leachate treatment of a landfill contains a lot of small, hard lumps. The original arc-shaped prism plate 12 can only stir and push the sludge, but cannot cut or break these hard lumps. After the hard lumps enter the subsequent stages with the sludge, they are easy to get stuck between the spiral conveyor blade 17 and the tank wall, causing conveying jams and even wear on parts. At the same time, the hard lumps may also block the discharge pipe, affecting the processing efficiency. At this time, the original arc-shaped prism plate 12 is replaced with an arc-shaped plate with serrations. The edges of the arc-shaped plate are added with fine serrations, and the arc curvature is consistent with the original arc-shaped prism plate to ensure that it does not affect the pushing of sludge.

[0070] When the serrated arc plate rotates with the drive shaft 14, the edge serrations can directly cut and break up small hard blocks in the sludge, avoiding hard block residue. The curved surface structure of the arc plate retains the pushing function of the original arc prism plate 12. While cutting hard blocks, it smoothly guides the sludge to the conical end of the inclined conical tank 8. Compared with the original structure, it not only solves the problem of hard block blockage, but also does not affect the sludge conveying rhythm.

[0071] The serrated structure enhances the contact area with the sludge, which can more fully break up sludge agglomerates during stirring. Combined with the spiral blades 15 on the drive shaft 14, it realizes the integration of stirring-cutting-pushing. After the hard blocks are broken, they enter the conveying tank 6 with the sludge and can be further processed by the subsequent diamond column. There are no hard blocks left in the whole process. Together with the secondary crushing in the conveying tank 6, it forms a complete anti-clogging chain.

[0072] The serrations are made of wear-resistant alloy material, which is not easily worn by cutting hard blocks, thus extending the service life. The installation method of the arc plate with serrations is the same as that of the original arc prism plate 12. It can be directly fixed to the drive shaft 14 through the fixing sleeve 13 without modifying the structure of the inclined conical tank 8 or the second drive motor 9. It is easy to disassemble and clean, and is suitable for batch processing of sludge containing hard blocks.

[0073] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
