Description

Technical Field

[0001] This utility model relates to the technical field of filter cloth replacement devices, specifically to a filter cloth replacement mechanism for a filter press. Background Technology

[0002] Filter cloth, a crucial component in solid-liquid separation, directly impacts the efficiency and effectiveness of the entire filtration process with its performance and quality. Like a silent yet vital guardian, it stands quietly at the heart of the filter press, precisely intercepting solid particles suspended in the liquid with its unique material structure and meticulous weaving process, ensuring the clarity and purity of the filtrate.

[0003] Furthermore, the tightness of the fit between the filter cloth and the filter plate is extremely important to ensure filtration efficiency. This makes it difficult to achieve an ideal fit when replacing the filter cloth. If the fit is not tight, problems such as leakage will occur, severely affecting the normal operation of the filter press. Moreover, in some large filter presses, the filter cloth is enormous and heavy, making replacement impossible for a single person; multiple people are required, further increasing the complexity and time cost of the replacement process. Utility Model Content

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a filter cloth replacement mechanism for a filter press, which can effectively solve the problems in the existing technology.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a filter cloth replacement mechanism for a filter press, including an outer disc and an inner ring fixed inside the outer disc. A retaining ring is fixed on both the inner and outer walls of the inner ring. A locking disc is sleeved on the outer side of the retaining ring. The locking disc is a hollow frame structure with no bottom face. A positioning screw and a hook are fixed on the top of the outer disc.

[0009] Furthermore, the middle part of the locking disc protrudes outwards to both ends, and the bottom end of the locking disc is interference-fitted and fixed to the retaining ring.

[0010] Furthermore, multiple sets of positioning screws and hooks are arranged in an equidistant array on the outer disk, and a nut is fitted onto the top of each set of positioning screws.

[0011] Furthermore, the card holder is made of stainless steel.

[0012] Furthermore, the outer sides of both retaining rings are rounded. Beneficial effects

[0013] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0014] This invention utilizes a locking disc structure to place the filter cloth on the outside of the retaining ring and the outside of the inner ring, finally hanging it onto the positioning screw through holes in the filter cloth. The filter cloth is then fixed to the positioning screw, and finally, the locking disc secures the filter cloth downwards from the inner ring. The retaining ring connects and secures the filter cloth to the external hanging structure, thus fixing it within the locking disc and achieving a combined function. Disassembly is simple: remove the locking disc and filter cloth, and then follow the steps above to secure a new filter cloth for replacement. Therefore, this device, through the interference fit of the locking disc, enables rapid filter cloth replacement and fixation, saving operator effort and reducing replacement steps compared to existing structures.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example: A filter cloth replacement mechanism for a filter press, as shown in the attached document. Figure 1 - Appendix Figure 4 It includes an outer plate 1 and an inner ring 2 fixed inside the outer plate 1. A retaining ring 6 is fixed on both the inner and outer walls of the inner ring 2. A locking plate 3 is sleeved on the outer side of the retaining ring 6. The locking plate 3 is a hollow frame structure with no bottom face. A positioning screw 5 and a hook 4 are fixed on the top of the outer plate 1.

[0024] The middle of the retaining disc 3 protrudes outwards to both ends, and the bottom end of the retaining disc 3 is press-fitted and fixed to the retaining ring 6. Multiple sets of positioning screws 5 and hooks 4 are arranged equidistantly on the outer disc 1, and each set of positioning screws 5 has a nut fitted at its top. The retaining disc 3 is made of stainless steel. The outer sides of the retaining rings 6 on both sides have rounded corners. Through the structure of the retaining disc 3, the filter cloth is fitted onto the outer side of the retaining ring 6 and the outer side of the inner ring 2, and finally hung on the positioning screw 5 through the holes in the filter cloth, thus securing it to the positioning screw 5. The filter cloth is then hung up, and finally, the clamping plate 3 is used to fix the filter cloth downward from the inner ring 2. It is then connected and fixed to the external hanging structure through the retaining ring 6. The filter cloth can then be fixedly clamped inside the clamping plate 3, realizing the combination function. At the same time, when disassembling, the clamping plate 3 and the filter cloth can be removed, and the new filter cloth can be fixed through the above steps to complete the replacement. Therefore, when using this device, the interference fit of the clamping plate 3 enables the quick replacement and fixing of the filter cloth. Compared with the existing structure, it can save the operator's physical strength and the number of replacement steps.
