Description

Technical Field

[0001] This invention belongs to the technical field of solid-liquid separation equipment, specifically referring to a vehicle-mounted sludge dewatering device. Background Technology

[0002] In the field of industrial solid-liquid separation, sludge is a common material to be treated. Its complex composition and high water content typically require dewatering and volume reduction. Filter press technology is a key method for achieving this process, its principle being the forced separation of the liquid and solid phases in the material through mechanical pressure. Currently, plate and frame filter presses, chamber filter presses, and other similar equipment are widely used in sludge dewatering and other solid-liquid separation applications. However, in actual operation, their filtration performance is still constrained by the following common technical problems.

[0003] Firstly, in the initial stage of filtration, compressible materials such as sludge are typically in a flowable state. Traditional filter presses use rigid, flat plates. When these plates come into contact with the material and pressure is applied, uneven flow or bridging can easily occur between solid particles due to instantaneous pressure, resulting in a non-uniform particle accumulation structure. This problem leads to uneven pressure distribution across the filtration cross-section, causing premature closure of filtration channels in some areas, reducing the effective filtration area, and consequently decreasing overall filtration efficiency and extending the filtration cycle.

[0004] Secondly, in the later stages of filtration, as the liquid phase is gradually extruded, a dense filter cake layer forms on the surface of the filter cloth. Taking sludge as an example, this filter cake layer and the filter cloth exhibit significant adhesion due to interfacial adhesion, and the filter cake layer itself also becomes a major source of filtration resistance. Traditional equipment at this stage mainly relies on continuous pressurization or mechanical intervention to achieve filter cake removal, which not only increases energy consumption but also easily causes filter cloth clogging, filter cake residue, and even damage to the filter cloth due to localized stress concentration, seriously affecting the reliability of continuous equipment operation and the service life of the filter cloth.

[0005] In addition, most existing filter press equipment is fixed or skid-mounted. In scenarios with multiple locations and short cycles, such as sewage treatment plants and emergency response sites, the equipment lacks flexibility in transportation and deployment. During the movement, it often relies on external hoisting equipment for loading and unloading, and the fixing process is cumbersome, making it difficult to meet the needs of rapid response operations.

[0006] In summary, there is an urgent need to provide a filter press device that can adapt to different stages of filter press, improve filtration uniformity and efficiency, enhance filter cake peeling, and has convenient transport capabilities, so as to overcome the technical bottlenecks of existing solid-liquid separation equipment in terms of filtration efficiency, operational reliability, and mobile deployment. Summary of the Invention

[0007] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a vehicle-mounted sludge filter press. Through the ingenious linkage between the secondary pressure plate and the spring-connecting rod-wedge mechanism, the vibration mode can adaptively switch according to the physical property changes of the material to be filtered from fluid to solid during the filter press process. This achieves a closed-loop process of initial vibration to aid filtration and subsequent vibration to remove the filter cake, overcoming the industry bottlenecks of rapid filtration flux decay and difficult filter cake removal in traditional filter press equipment. Furthermore, the device integrates a rapid vehicle mounting and locking mechanism, combining efficient solid-liquid separation with flexible deployment capabilities, significantly improving the overall efficiency and adaptability of filter press operations.

[0017] Furthermore, the fixed frame is provided with a pull-out frame, and rollers are provided on the two opposite inner sidewalls of the pull-out frame.

[0018] The beneficial effects achieved by the present invention using the above structure are as follows: 1. Adaptive, phased intelligent vibration significantly improves solid-liquid separation efficiency and quality: This invention creatively utilizes the linkage design of the secondary pressure plate, support spring, and connecting rod-wedge-vibration rod transmission mechanism to automatically match the vibration function with the filtration process. In the initial stage of filtration, the secondary pressure plate is pushed back by the flowing sludge to be filtered, triggering the spring-loaded vibrating component to continuously vibrate the main pressure plate. This vibration is transmitted to the interior of the sludge, effectively disrupting early bridging of the filter cake structure, reducing interparticle gaps, and creating channels for liquid phase permeation, overcoming the problem of low filtration flux in the initial stage of static pressure filtration. In the later stage of filtration, as the filter cake solidifies and shrinks, the support spring releases its elasticity to push the secondary pressure plate back to its original position, triggering continuous vibration again. At this time, the vibration acts on the filter bag through the main and secondary pressure plates, causing the filter cake to loosen and fall off. This adaptive vibration mechanism, which uses initial compaction to prevent clogging and later vibration to aid separation, significantly improves the filtration rate and final solids content of the filter cake throughout the entire filtration cycle. 2. Solved the problem of filter cake adhesion and achieved automated cleaning and unloading: Through the above-mentioned post-processing vibration mechanism, the device can automatically and continuously transmit vibration to the filter bag at the end of the filtration process, so that the hard filter cake can be efficiently and completely peeled off from the filter bag under the action of vibration. This completely avoids the problem of manual cleaning that traditional equipment requires to stop. Combined with the automatic linkage design of the opening and closing plate and the filter cake collection box, the entire process of unloading and collection is automated, which greatly reduces the intensity of manual labor and improves the continuity and safety of equipment operation. 3. Integrating high-efficiency filtration and convenient transportation functions, with a high degree of modularity: This invention integrates the filter press host, filtrate / filter cake collection unit and quick vehicle mounting mechanism into one unit. Through the unique design of pull-out ladder, loading platform and roller slide, the bulky filter press can be easily and smoothly moved to the transport vehicle. Furthermore, the movement of the wheels is controlled by an electric push rod, and it can be directly fixed through the mounting holes after being retracted. This achieves a quick and reliable conversion from working state to transportation state. This design makes the device have both the high processing efficiency of fixed equipment and the deployment flexibility of mobile equipment, and is particularly suitable for temporary work sites, decentralized processing and emergency response scenarios. 4. Ingenious structural design, reasonable energy utilization, and stable and reliable operation: The entire adaptive vibration system uses the reaction force of the sludge to be filtered and the energy stored in the spring as the driving force. The mechanical linkage is reliable and there is no need to configure an additional complex electronically controlled vibrator or sensor. The sub-pressure plate simultaneously undertakes multiple functions such as transmitting pressure, triggering vibration, and guiding the filtrate. The structure is compact. The filtrate is collected through the filtrate holes on the sub-pressure plate to the outlet pipe, realizing the orderly diversion and collection of solid-liquid separation. The overall system has high energy utilization efficiency, stable operation, and simple maintenance. Attached Figure Description

The main pressure plate 9 is slidably disposed in the locking groove 24; a sleeve frame 25 is provided on the outer wall of the main pressure plate 9, and the main pressure plate 9 is slidably disposed on the fixed plate frame 1 through the sleeve frame 25. The main pressure plate 9 is provided with a liquid outlet pipe 26, and the secondary pressure plate 10 is provided with a filtrate hole 27. The secondary pressure plate 10 and the main pressure plate 9 are respectively provided with a feed hole 28. A telescopic connecting pipe is provided at the feed hole 28 between the secondary pressure plate 10 and the main pressure plate 9. A feed injection pipe is connected to the feed hole 28 on the main pressure plate 9. The left pressure filter element 6 and the right pressure filter element 7 have the same structure and connection relationship. A filter cloth bag 29 is provided between the secondary pressure plates 10, and the bottom of the filter cloth bag 29 is open.

[0027] The filter cake collection box 4 includes a box body 30, an opening and closing plate 31, and an opening and closing motor 32. The box body 30 is mounted on a fixed plate frame 1. The opening and closing plate 31 is rotatably mounted at both ends of the box body 30. The opening and closing motor 32 is mounted at both ends of the box body 30. The output end of the opening and closing motor 32 is connected to the opening and closing plate 31. The box body 30 is provided with a material receiving door 33.

[0028] In practical use, the lower opening of the filter bag 29 is clamped by the opening and closing plate 31. The sludge to be filtered is injected into the filter bag 29 between the secondary pressure plates 10 through the telescopic connecting pipe at the feed hole via the injection pipe. After injection, the cylinder 8 is started. The cylinder 8 pushes the left filter element 6 and the right filter element 7 to move towards each other. In the initial state, the secondary pressure plate 10 protrudes from the working plane of the main pressure plate 9. In the initial stage of filtration, the main pressure plate 9 moves forward, and the secondary pressure plate 10 contacts the material first. Since the material is flowable and compressible, the secondary pressure plate 10 is pushed back, compressing the support spring 15 behind it, until it is flush with the main pressure plate 9. During this process, the connecting rod 11 moves accordingly, pushing the wedge block 12 to move, pushing the vibrating head upward, and then pushing the vibrating rod 17 upward. The upward movement of the vibrating rod 17 pushes the trigger column 22 upward, which in turn pushes the vibrating lever 18 to rotate and strike the main pressure plate 9. The main pressure plate 9 can transmit the vibration generated during the strike to the material, which can reduce the gap between the materials. The vibrating head can continuously pass through the oscillation groove 16, achieving the technical effect of continuous and uninterrupted vibration of the main pressure plate 9, continuously reducing the gap between the materials. In the later stage of filter pressing (filter cake solidification and volume shrinkage), when the liquid phase in the filter cake is pressed out to the critical point, becomes hard, and begins to shrink in volume due to solid phase concentration, the reaction force acting on the auxiliary pressure plate 10 decreases. The support spring 15 behind the auxiliary pressure plate 10, which has been stored in the spring, is released, and the force changes from being balanced by the material reaction force to being greater than that after the filter cake shrinks. The residual reaction force causes the support spring 15 to push the secondary pressure plate 10 to slowly (following the shrinkage speed of the filter cake) return to its initial protruding position. During this process, the elastic force of the support spring 15 is greater than that of the return spring 21, causing the vibrating head to continuously return to its original position through the oscillation groove 16. At the same time, it drives the striking vibration lever 18 to continuously strike the main pressure plate 9, thereby transmitting the vibration to the filter bag 29. This causes the filter cake in the filter bag 29 to fall off quickly through vibration. Simultaneously, the opening and closing motor 32 is activated. The rotation of the opening and closing motor 32 drives the opening and closing plate 31 to rotate. The rotation of the opening and closing plate 31 opens the filter cake collection box 4, allowing the filter cake after solid-liquid separation to fall into the filter cake collection box 4. The filtrate generated during the solid-liquid separation process passes through the filter on the secondary pressure plate 10. Liquid is transferred from the liquid outlet 27 to the liquid outlet pipe 26 and discharged into the filtrate collection tank 3. When vehicle loading is required, the pull-out ladder 34 can be pulled out from the pull-out frame 39, and the mounting plate 35 can be placed on the vehicle. Pushing the device along the pull-out ladder 34 will allow it to move along the slide 38 via the rollers 40 to the vehicle. After the movement is complete, the pull-out ladder 34 can be retracted into the pull-out frame 39. The electric push rod 46 is activated, and the electric push rod 46 retracts, causing the fixing plate 47 to move upward. The upward movement of the fixing plate 47 causes the moving wheel 48 to move upward, so that the moving wheel 48 is retracted into the retraction cavity 44. The device is then fixed to the vehicle through the mounting hole 43, completing the rapid vehicle loading. The above is the specific working process of this invention. This step can be repeated for the next use.
