Description

Multi-station collaborative high-efficiency filter press system Technical Field

[0001] This utility model relates to the technical field of solid-liquid separation equipment, and in particular to a multi-station collaborative high-efficiency pressure filtration system. Background Technology

[0002] In environmental protection, food processing, and chemical production, solid-liquid separation is a crucial step in material handling, especially for high-volume, easily dewatered materials such as municipal sludge, distiller's grains, and pharmaceutical residues. The processing of these materials presents significant contradictions in their process characteristics: on the one hand, these materials have high moisture content and strong particle flowability, requiring a uniform filling of the material frame during the feeding process to ensure effective filtration, with each feeding cycle typically taking 30-60 minutes; on the other hand, due to their loose structure and low dewatering resistance, solid-liquid separation can be completed in as little as 10-20 minutes. With the increasing scale of industrial production, the daily processing demand of hundreds of tons or more places higher demands on the efficiency of filter press equipment. However, traditional filter press technology suffers from a mismatch between the slow feeding and fast filtration processes, resulting in the filter press unit being idle for extended periods during the feeding stage, hindering equipment capacity and becoming a technical bottleneck restricting efficient production in the industry.

[0003] Existing mainstream filter press equipment mainly consists of single-station plate and frame filter presses or fixed multi-station combined systems. Their core workflow follows a serial logic of "material feeding → filtration → discharge". Single-station filter press systems are equipped with only one material frame and one material feeding device. The next material frame can only be started after the previous material frame has completed the entire process of material feeding, filtration, and discharge, resulting in extremely low production efficiency. Fixed multi-station filter press systems increase the number of material frames and fix the main machine station layout to achieve sequential filtration of multiple material frames. However, the material feeding process is still a single-threaded operation. That is, the main machine can only start filtration sequentially at each station after all material frames have been fed. Some improvement solutions introduce multiple material feeders for parallel material feeding, but this only shortens the initial material feeding time and does not solve the asynchronous coordination problem between the material feeding and filtration processes. The equipment as a whole is still in a fragmented state where the main machine is stopped during material feeding and the material feeders are idle during filtration. Equipment resources cannot be efficiently reused.

[0004] The existing single-station or fixed multi-station filter press systems mentioned above struggle to balance the process rhythm of "slow material feeding" and "fast filter pressing," resulting in low equipment utilization and insufficient capacity, failing to meet the large-scale dewatering demand of hundreds of tons per day. Therefore, there is an urgent need to develop a filter press system that can achieve multi-station collaborative operation and efficient reuse of process time. Summary of the Invention

[0005] To address the aforementioned technical issues, this utility model provides a multi-station collaborative high-efficiency filter press system. By reconstructing the timing of cross-processes and coordinating multiple devices in parallel, it transforms the serial waiting of the traditional filter press system into asynchronous rotation, achieving multiple breakthroughs in equipment utilization, production efficiency, and process automation in high-volume dewatering scenarios.

[0006] To achieve the above objectives, this utility model provides a multi-station collaborative high-efficiency filter press system, including a station support, a drive mechanism, a filter press host, and at least two material feeders. The drive mechanism and the filter press host are mounted on the station support. The output end of the drive mechanism is connected to the filter press host to drive the filter press host to move linearly back and forth on the station support. Each material feeder is mounted on one side of the station support and is arranged along the moving direction of the filter press host. Each material feeder is equipped with a corresponding material frame, and the hydraulic cylinder on the material feeder can drive the material frame to move back and forth between the material feeder and the station support.

[0007] In use, all the cloth feeders simultaneously feed the material. After feeding, the first cloth feeder pushes the material frame onto the workstation support, and the filter press moves to the material frame to perform filter pressing. After filter pressing, the material frame returns to its initial position to feed the material. The next cloth feeder pushes the material frame onto the workstation support, and the filter press moves to the material frame to perform filter pressing. After filter pressing, the material frame returns to its initial position to feed the material, and so on, in a continuous cycle.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. This solution transforms the serial waiting of the traditional filter press system into asynchronous rotation by reconstructing the timing of cross-processes and coordinating multiple devices in parallel, forming a closed-loop process of "initial parallel material feeding → station rotation filter pressing → filter pressing → asynchronous overlapping of material feeding". Its core innovation is not an improvement of a single device, but a systematic design of process logic that achieves multiple breakthroughs in equipment utilization, production efficiency and process automation in high-volume dewatering scenarios, demonstrating significant technological progress and application value.

[0010] 2. Traditional filter press systems typically use a single material feeder or sequential material feeding, which results in long feeding times for a single material frame and the inability to reuse equipment. This solution is the first to use four material feeders to simultaneously feed four material frames initially, breaking through the serial limitation from a single material feeder to a single material frame. This reduces the initial feeding time to the same as the feeding time for a single material frame, achieving the effect of doubling the production capacity while keeping the time the same.

[0011] 3. When the single material frame is independently fed in the subsequent process, it is asynchronous and parallel with the filter pressing process, forming a dual process of filter pressing and feeding in parallel, thus avoiding the idleness of the feeding machine during the filter pressing stage.

[0012] 4. Traditional multi-station filter presses often use a fixed-station feeding and material frame transport method, or require waiting for all material frames to be filled before sequentially pressing, resulting in idle time for the main unit. This solution actively switches the main unit according to the station sequence, combined with a timing design that allows material to be added immediately after filtration, so that the main unit can directly enter the next station without waiting during the filtration interval, creating a continuous process of filtration, transfer, and filtration, theoretically eliminating the idle time of the main unit.

[0013] 5. Materials that are easy to dewater have short filter press cycles but long feeding cycles. Traditional systems often experience frequent waiting times for the main unit due to slow feeding and fast filter press. This solution uses a hybrid mode of initial parallel operation of multiple feeders and subsequent serial operation of a single feed frame. This satisfies the efficiency requirements for the first large-scale feeding and solves the matching problem between fast and slow processes through asynchronous rotation of subsequent filter press and feeding, thus achieving a dedicated optimization for specific materials.

[0014] 6. The first cycle completes the 4-station filter press. In subsequent cycles, the material frame has entered the rotation state from material feeding to filter press, and one filter press can be completed every 15 minutes. This forms a similar assembly line effect with a long first cycle and a short subsequent cycle, which meets the needs of continuous production and rapid turnover in high-volume scenarios, rather than simply repeating a fixed cycle.

These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] This utility model discloses a multi-station collaborative high-efficiency pressure filtration system.

[0019] Referring to Figure 1, a multi-station collaborative high-efficiency filter press system includes a station support 1, a drive mechanism, a filter press host 2, and at least two material feeders 3. In this embodiment, the time required for a single material feeding operation is 40 minutes, the time required for a single filter press operation is 10 minutes, and four material feeders 3 are provided.

[0020] The drive mechanism and the filter press 2 are mounted on the workstation support 1. The output end of the drive mechanism is connected to the filter press 2 to drive the filter press 2 to move linearly back and forth on the workstation support 1. The drive mechanism can be a ball screw mechanism, gear and rack mechanism, chain drive mechanism, electric push rod, or cylinder, as long as it can drive the filter press 2 to move back and forth. Four material feeders 3 are all set on one side of the workstation support 1 and arranged along the moving direction of the filter press 2. Each material feeder 3 is equipped with a corresponding material frame 4. The hydraulic cylinder on the material feeder 3 can drive the material frame 4 to move back and forth between the material feeder 3 and the workstation support 1. The workstation support 1 forms a corresponding workstation corresponding to the position of each material feeder 3. For ease of description, the four workstations are set as shown in Figure 1, and are named workstation 1, workstation 2, workstation 3, and workstation 4 from left to right.

[0021] During operation, four material feeders 3 simultaneously feed material. After 40 minutes, the feeding process ends, and the filter press 2 initially resides at station 1. The material feeder 3 at station 1 pushes the material frame 4 onto the station support 1, and the filter press 2 begins filtration. The other three material frames 4 wait. After 15 minutes, the material frame 4 at station 1 finishes filtration, moves back to its starting position, and begins discharging. Immediately after discharging, material feeding begins, followed by a wait. During this process, the filter press 2 moves to station 2, where the material feeder 3 moves the material frame 4 onto the station support 1 and begins filtration. After 15 minutes, the material frame 4 at station 2 finishes pressing, moves back to its starting position, and begins discharging. Immediately after discharging, material feeding begins, followed by a wait. This process is repeated. During the process, the filter press 2 moves to station 3. The material feeder 3 at station 3 moves the material frame 4 onto the station support 1, and then begins filtration. After 15 minutes, the material frame 4 finishes pressing, moves back to its starting position, and begins discharging. Immediately after discharging, material feeding begins, followed by a waiting period. Meanwhile, the filter press 2 moves to station 4. The material feeder 3 at station 4 moves the material frame 4 onto the station support 1, and then begins filtration. After 15 minutes, the material frame 4 finishes pressing, moves back to its starting position, and begins discharging. Immediately after discharging, material feeding begins, followed by a waiting period. At this point, the material feeder 3 at station 1 has completed material feeding, and the filter press 2 moves back to station 1. This process repeats until the required filtration operation is completed. The workflow table for each station during operation is as follows:
