Description

Technical Field

[0001] This utility model relates to the field of accessories for ternary cathode precursor material production equipment, specifically to a filter plate for a filter press with a uniform water spray structure. Background Technology

[0002] As a key piece of equipment in the field of solid-liquid separation, filter presses are widely used in industries such as chemical, mining, and environmental protection. In the production of ternary cathode materials, they play a crucial role in mixing and rinsing the precursor with the cleaning solution and separating the solid and liquid components. The filtration efficiency and service life of the filter plates, its core working component, directly affect the overall performance of the machine. During the filter press cycle, the mixing effect and rinsing uniformity of the ternary cathode precursor and the cleaning solution on the filter plate surface and in the relevant flow channels are critical to ensuring the purity of the subsequent products. If rinsing is incomplete or mixing is uneven, residual precursor impurities will affect product quality. Furthermore, inconsistent rinsing volumes in some areas will lead to reduced raw material utilization and increased production costs.

[0003] Existing filter presses often employ a fixed nozzle design for cleaning filter plates. In the rinsing and mixing of ternary cathode precursors, the water flow from the fixed nozzles is difficult to avoid the obstruction of these turbulence structures within the flow channel to improve mixing efficiency. This results in a concentrated rinsing area, failing to evenly cover the entire working surface. For example, some filter plates have protrusions, baffles, or other turbulence-causing components within the flow channels. The water flow from the fixed nozzles is blocked by these components, leading to insufficient rinsing volume behind the turbulence-causing components and at flow channel corners, while the area directly opposite the nozzle experiences excessive rinsing volume. This inconsistent rinsing volume across the entire working surface severely affects the uniformity of mixing between the ternary cathode precursor and the cleaning solution.

[0004] Furthermore, in traditional rinsing mechanisms, the nozzles and channels are mostly fixedly connected. When the nozzles become clogged or worn due to precursor particles, the entire filter plate must be disassembled for maintenance, which is cumbersome and disrupts continuous equipment operation. Simultaneously, existing filter plate rinsing and drainage designs often lack a reasonable flow guiding structure, preventing the rinsed mixture from draining quickly and causing liquid accumulation in the channels. This not only affects subsequent rinsing effects but also leads to channel blockage due to precursor residue, further exacerbating the problem of uneven rinsing. These issues make it difficult for existing filter press plates to maintain stable rinsing effects during ternary cathode precursor rinsing and mixing operations, restricting the filter press's working efficiency and product quality. Therefore, developing a filter plate structure that can achieve uniform water spray, full coverage of the working surface, and ease of maintenance has become an urgent need in the industry. Summary of the Invention

[0005] The problem this utility model aims to solve is to provide a filter plate for a filter press with a uniform water spray structure, so as to achieve uniform water spray, full coverage of the working surface and easy maintenance.

[0006] The technical solution adopted by this utility model to solve the above problems is as follows: a filter plate for a filter press with a uniform water spray structure, comprising: a filter plate frame, with water inlets at the top two corners, water outlets at the bottom two corners, and a mounting cavity with a through thickness in the middle; a baffle, embedded in the mounting cavity, with spaced protrusions on its working surface, and crisscrossing flushing channels formed between adjacent protrusions; a flushing mechanism, including side spray structures symmetrically arranged on both sides of the filter plate frame and a top spray structure at the top; a water discharge channel, located at the bottom of the filter plate frame, with its top end connected to the lowest position of the flushing channel and its bottom end connected to the water outlet; the side spray structure includes a side main channel and side nozzles, the side main channel being used to connect to the water inlet, and the side nozzles being arranged longitudinally at intervals and facing the transverse channel of the baffle; the top spray structure includes a top main channel and top nozzles, the top main channel being used to connect to the water inlet, and the top nozzles being arranged transversely and facing the longitudinal channel of the baffle.

[0007] By employing a synergistic design of a side-spray structure (the side main channel connects to the inlet, and the side nozzles are arranged longitudinally at intervals and facing the transverse flow channel of the baffle) and a top-spray structure (the top main channel connects to the inlet, and the top nozzles are arranged laterally and facing the longitudinal flow channel of the baffle), water flow is achieved by cross-covering the working surface of the baffle from both transverse and longitudinal dimensions. This solves the problem of concentrated rinsing areas and incomplete coverage caused by the obstruction of the fixed nozzles due to the turbulence structure, ensuring uniform mixing of the ternary cathode precursor and the cleaning solution across the entire working surface. The crisscrossing rinsing channels formed by the spaced protrusions on the working surface of the baffle allow for orderly diffusion and uniform distribution of water flow within the channels. This addresses the problem of insufficient or excessive rinsing volume in some areas caused by obstruction of the flow channels by existing filter plates, preventing residual precursor impurities from affecting product quality and reducing raw material utilization. The flow-guiding design of the water discharge channel (connected to the lowest point of the flushing channel at the top and to the water outlet at the bottom) enables the rapid discharge of the mixed liquid after flushing, solving the problems of liquid accumulation, precursor residue and channel blockage caused by the lack of a reasonable flow-guiding structure in traditional filter plates, and ensuring stable subsequent flushing effect.

[0008] Furthermore, the side spray structure also includes side spray plates detachably installed on both sides of the filter plate frame, and the top spray structure also includes a top spray plate detachably installed on the top of the filter plate frame. This structure, with its detachable side spray plates on both sides of the filter plate frame and its detachable top spray plate on the top of the filter plate frame, enables rapid assembly and disassembly of both the side spray structure and the top spray structure. This solves the problem of difficult overall maintenance and replacement caused by the fixed connection between the nozzle and the flow channel in traditional methods, further improving maintenance convenience.

[0009] Furthermore, the filter plate frame has side mounting grooves on both sides, and the side spray plates are slidably fitted into the side mounting grooves; the filter plate frame also has a top mounting groove on the top, and the top spray plates are slidably fitted into the top mounting groove. Through the side mounting grooves on both sides of the filter plate frame and the slidable fitting of the side spray plates into the side mounting grooves, and the top mounting groove on the top of the filter plate frame and the slidable fitting of the top spray plates into the top mounting grooves, the accuracy of the installation and positioning of the side spray plates and top spray plates is achieved, as well as the smoothness of their installation and disassembly. This solves the problems of inaccurate alignment and laborious installation and disassembly of the side spray plates and top spray plates, improving maintenance efficiency.

[0010] Furthermore, the side spray plate has side-hanging protrusions at its upper and lower ends, and corresponding side-hanging recesses in the side mounting groove, forming an interlocking fit; the top spray plate has top-hanging protrusions on both sides, and corresponding top-hanging recesses in the top mounting groove, forming an interlocking fit. This structure, where the side-hanging protrusions at the upper and lower ends of the side spray plate interlock with the corresponding side-hanging recesses in the side mounting groove, and the top-hanging protrusions on both sides of the top spray plate interlock with the corresponding top-hanging recesses in the top mounting groove, ensures the stability of the side spray plate and top spray plate after installation, solves the problem of loosening caused by water flow impact during operation, and guarantees the stability of the water spray structure.

[0011] Furthermore, the side spray plate and the top spray plate are respectively fixed to the filter plate frame with fastening screws. By fixing the side spray plate and the top spray plate to the filter plate frame with fastening screws, the reliability of the connection between the side spray plate and the top spray plate and the filter plate frame is achieved, solving the problem of weak connection that may exist with plug-in joints. At the same time, it is easy to quickly disassemble when needed, taking into account both stability and ease of maintenance.

[0012] Furthermore, the protruding structure is a cylindrical structure with a semi-circular top, arranged in an array on the working surface of the baffle. By using a cylindrical structure with a semi-circular top and arranged in an array on the working surface of the baffle, the resistance encountered by the water flow within the flushing channel is reduced, and the water flow is evenly dispersed. This solves the problems of turbulent water flow and insufficient local flushing force caused by unreasonable protruding structure shapes, ensuring the uniformity of flushing.

[0013] Furthermore, the side and top nozzles are fan-shaped or conical nozzles, with a spray angle covering the flow channel cross-section between adjacent protruding structures. By using fan-shaped or conical nozzles for the side and top nozzles and ensuring the spray angle covers the flow channel cross-section between adjacent protruding structures, the sprayed water flow can fully cover the flow channel cross-section, solving the problem of insufficient spray angle in traditional nozzles that prevents some areas within the flow channel from being rinsed, thus further improving the comprehensiveness of rinsing.

[0014] Furthermore, the working surface of the baffle is an arc-shaped surface that continuously decreases from the edge to the center, so that the depth of the flushing channel continuously decreases from the edge to the center. This structure, where the working surface of the baffle is an arc-shaped surface that continuously increases from the edge to the center, causes the water flow velocity at the center to increase due to the reduced cross-sectional area of ​​the channel, thus reducing the impact of the decreased intensity of the water flow as it flows from the edge to the center.
