DETAILED DESCRIPTION

[0027] The following is a detailed description of a plate-frame filter press device for nickel sulfate production provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some known technologies, those skilled in the art may also adopt other alternative methods to implement them; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0028] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, an embodiment of the utility model provides a plate and frame filter press device for nickel sulfate production, comprising: a plate and frame filter press body 1; a plurality of filter parts 5, which are arranged on the plate and frame filter press body 1 through a connecting piece 6, and the filter parts 5 include: a filter frame 501, and the filter frame 501 is a frame with a middle hollow profile; a filter plate 503, which is detachably mounted on the filter frame 501, and the edge of the filter plate 503 is wavy or concave-convex; an outer filter screen 502 and an inner filter screen 504, which are both mounted on the filter frame 501 and the filter plate 503, and the outer filter screen 502 is made of acid and alkali resistant and high-strength material to resist the corrosion of the nickel sulfate solution, and the inner filter screen 504 is a microporous structure.

[0029] The plate and frame filter press body 1 is the core of the entire filtration system, providing a structural framework for installing and fixing multiple filter parts 5. The plate and frame filter press body 1 is usually made of strong and durable materials to withstand the pressure generated during the filtration process and ensure a safe and stable operating environment.

[0030] The function of the filter frame 501 is to support the filter cloth and the filter screen to form a space for the filter chamber. The filter frame 501 is combined with the filter plate 503 to provide space for the accumulation of solid particles and also create a path for the outflow of the filtrate. The filter plate 503 is designed with a wavy or concave-convex edge to increase the effective filtering area, thereby improving the filtering efficiency. The filter plate 503 not only supports the filter cloth, but also helps to enhance the mechanical strength of the entire filter unit 5. The outer filter screen 502 is made of acid-resistant and alkali-resistant, high-strength material. Its main function is to resist the erosion of corrosive liquids such as nickel sulfate solution. The outer filter screen 502 protects the inner filter screen 504 from chemical damage and extends the service life of the filter screen. The inner filter screen 504 is designed as a microporous structure to improve the filtering accuracy. It can capture smaller particles and ensure that only pure liquid passes through, thereby improving the filtering quality. The multi-layer filtering structure not only improves the filtering efficiency and accuracy, but also ensures the long-term stable operation of the equipment, especially in the production of nickel sulfate solution.

[0031] like Figure 1 , Figure 3 , Figure 8 and Fig. 9 As shown, the cleaning part 4 is installed on the plate and frame filter press body 1, and the cleaning part 4 includes: a mounting part 401; a plurality of water pipes 402 installed on the mounting part 401; a connecting pipe 404, detachably installed on the water pipe 402, for detachably connecting two adjacent water pipes 402.

[0032] The main function of the connecting pipe 404 is to connect two adjacent water pipes 402. This detachable design facilitates the maintenance and replacement of the cleaning part 4, and also provides flexible configuration options to adapt to plate and frame filter press bodies 1 of different sizes and layouts. These components of the cleaning part 4 together constitute an efficient cleaning system, which can ensure that the filter part 5 in the plate and frame filter press body 1 is cleaned in a timely and thorough manner, which not only extends the service life of the filter part 5, but also maintains the filtration efficiency and product quality. It is particularly suitable for occasions that require frequent cleaning, such as processing materials containing more impurities or continuous production processes.

[0033] like Figure 4 , Figure 8 and Fig. 9 As shown, the cleaning part 4 also includes: a plurality of steering high-pressure nozzles 403 , which are evenly installed on the connecting pipe 404 .

[0034] The main function of the steering high-pressure nozzle 403 is to spray the cleaning liquid in the form of high pressure to strongly clean the filter part 5. The design of the steering high-pressure nozzle 403 allows the spray angle to be adjusted to ensure that the cleaning liquid can cover every corner of the filter part 5, thereby completely removing the accumulated solid particles and residual pollutants. The uniform installation of the steering high-pressure nozzle 403 ensures the balance of the cleaning operation, so that each part of the filter part 5 can obtain an equivalent cleaning effect, which avoids blockage or contamination problems in certain areas due to insufficient cleaning.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, sealing cover 1 2 and sealing cover 2 3, sealing cover 1 2 is arranged on the plate and frame filter press body 1, sealing cover 2 3 is rotatably installed on sealing cover 1 2, and sealing cover 1 2 and sealing cover 2 3 form a closed space.

[0036] Sealing cover 1 2 and sealing cover 2 3 allow the plate and frame filter press body 1 to operate in a closed space, which allows the plate and frame filter press device 1 to operate in a controlled environment. This closed space is particularly important for handling toxic, harmful, flammable or volatile substances because it can prevent these substances from leaking into the working environment while also reducing pollution to the environment. This closed space ensures that the filtration process will not cause harm to the surrounding workers and the environment.

[0037] like Figure 4 As shown, the connecting piece 6 is a quick locking mechanism, which facilitates the quick replacement of the filter part 5.

[0038] The main function of the connector 6 is to provide a convenient and quick way to install and remove the filter unit 5. This mechanism usually adopts a locking mechanism that is easy to operate, such as a buckle, a knob or a lever.

[0039] like Figure 5 , Figure 6 and Figure 7 As shown, the filter frame 501 and the filter plate 503 are both made of high-performance corrosion-resistant alloy material and are provided with an anti-corrosion coating to enhance the corrosion resistance.

[0040] The main purpose of using high-performance corrosion-resistant alloy materials for the filter frame 501 and the filter plate 503 is to improve the durability and reliability of these components in harsh environments. Corrosion-resistant alloys generally have excellent chemical corrosion resistance and can resist corrosion by acids, alkalis, salts and other corrosive substances, thereby extending the service life of the filter frame 501 and the filter plate 503. The anti-corrosion coating is provided on the filter frame 501 and the filter plate 503 to provide an additional protective layer to further enhance the corrosion resistance of these components. The anti-corrosion coating can prevent corrosive substances from directly contacting the alloy material, thereby reducing the risk of corrosion. Such coatings are generally designed to be highly resistant to chemical corrosion and to withstand long-term exposure to corrosive environments. By using high-performance corrosion-resistant alloy materials and applying anti-corrosion coatings, the corrosion resistance of the filter frame 501 and the filter plate 503 is significantly improved, which not only reduces equipment damage and maintenance costs caused by corrosion, but also ensures the stability and safety of the filtration process. By reducing the replacement of components due to corrosion, the generation of waste is reduced, which is beneficial to environmental protection. At the same time, it reduces material consumption and maintenance costs, which is also cost-effective from an economic point of view.

[0041] like Figure 6 As shown, the mesh diameter of the outer filter 502 is slightly larger than the mesh diameter of the inner filter 504 .

[0042] The mesh diameter of the outer filter 502 is slightly larger than that of the inner filter 504, which can effectively improve the filtering efficiency. The outer filter 502 can quickly intercept larger particles and prevent them from entering the inner filter 504, thereby extending the service life of the inner filter 504 and maintaining its filtering accuracy. Since the outer filter 502 undertakes most of the coarse filtering tasks, the inner filter 504 can focus on capturing finer particles, which helps to protect the inner filter 504 from being blocked and damaged by large particles. By using the outer filter 502 for pre-filtration first, the contamination rate of the inner filter 504 is reduced, thereby reducing the frequency of replacing or cleaning the filter and reducing maintenance. Cost, the inner filter 504 can capture tiny particles more effectively, ensure the purity of the filtered liquid or gas, and improve the quality of the final product. The appropriately sized mesh diameter can reduce the resistance of the fluid passing through the filter, allowing the fluid to pass through the filter more smoothly, reducing energy consumption. The double-layer filter design provides higher system stability. Even if the outer filter 502 is blocked, the inner filter 504 can still continue to work, ensuring the continuity of the filtration process. The different mesh diameter designs of the outer filter 502 and the inner filter 504 enable the filtration device to adapt to a wider range of filtration needs, from coarse filtration to fine filtration, providing more flexibility.

[0043] The technical solution provided by the utility model is that when in use, the filter part 5 is protected by the sealing cover 1 2 and the sealing cover 2 3, and the solid-liquid separation of nickel sulfate is carried out. After the separation is completed, the sealing cover 2 3 is rotated to make the solid part fall off. When the filter part 5 needs to be cleaned, the steering high-pressure nozzle 403 in the cleaning part 4 can rinse the surface of the filter part 5.

[0044] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
