Description

Technical Field

[0001] The utility model relates to the technical field of quick-opening filter presses, and particularly relates to a quick-opening and rapid guiding structure for a pull plate. Background Technique

[0002] As an important part of modern solid-liquid separation technology, the quick-opening filter press is widely used in many industries such as chemical industry, pharmaceutical industry, food processing, and mining for efficiently separating solid-liquid mixtures. Its working principle is based on pressure filtration. By forming a filtration chamber between filter plates, the liquid in the suspension is discharged through the filter cloth under pressure, and the solid is retained on the filter cloth to form a filter cake, thereby realizing solid-liquid separation.

[0003] There are some inherent technical challenges in the operation of traditional filter presses, which are mainly reflected in the following aspects:

[0004] (1) Low efficiency of filter plate movement: In traditional designs, the opening, closing, and movement of filter plates are usually relatively slow, requiring a long preparation time, which reduces the overall processing capacity and production efficiency of the equipment;

[0005] (2) Operational complexity: The operation process of traditional filter presses is relatively cumbersome, including the individual opening and closing of filter plates, the unloading of filter cakes, etc., which requires high skills from operators, increasing labor costs and operation time;

[0006] (3) Insufficient structural stability and adaptability: When dealing with materials with different characteristics or under different working conditions, the structural stability and adaptability of traditional filter presses are limited, and it is difficult to achieve efficient and stable continuous operation;

[0007] (4) High maintenance cost: Due to complex structures and material limitations, the maintenance and repair costs of traditional filter presses are relatively high, and frequent maintenance requirements affect the long-term operation efficiency of the equipment.

[0008] In the prior art, during the use of a quick-opening filter press, multiple filter plates in each group cannot be pushed simultaneously, which easily causes the problem of incomplete unhooking of the pull plate trolley; therefore, we make improvements and propose a quick-opening and rapid guiding structure for a pull plate.

[0035] As Figures 1-5 shown, this embodiment provides a quick-opening pull plate quick guiding structure, including a pull plate trolley 1 and a filter plate 4. Linkage handles 2 are provided at both ends of the filter plate 4. A linkage frame 3 is provided at the outer end of the linkage handle 2.

A fixed rod 9 is provided at the inner end of the movable guiding frame 8. A positioning cylinder 14 is provided at the outer end of the fixed rod 9. A threaded rod 15 is provided at the inner end of the positioning cylinder 14. An adsorption rod 16 is provided at the outer end of the threaded rod 15.

Rotating rods 10 are connected to both ends of the lower group of telescopic rods 11.

[0036] The linkage handles 2 are fixed at both ends of the filter plate 4. The linkage frame 3 is framed at the outer end of the linkage handle 2. The left end of the linkage frame 3 is penetrated by the through hole 19. A fixed connection is provided between the left end of the linkage frame 3 and the fixed guiding frame 7.

[0037] Through the connection between the linkage handle 2 and the linkage frame 3, the linkage of the filter plate 4 is realized, facilitating the simultaneous movement of multiple filter plates 4 and improving the operation efficiency.

[0038] The combination of the telescopic rods 11 and the rotating rods 10 allows for flexible adjustment of the movable guiding frame 8 relative to the fixed guiding frame 7, adapting to the guiding requirements of different numbers of filter plates 4 and enhancing the adaptability and flexibility of the structure.

[0039] The inner end of the fixed guiding frame 7 is penetrated by the through hole 19. The adsorption rod 16 slides left and right along the through hole 19.

[0040] A fixed connection is provided between the left end of the adsorption rod 16 and the threaded rod 15. The left end of the threaded rod 15 slides within the positioning cylinder 14. A fixed connection is provided between the positioning cylinder 14 and the fixed rod 9.

[0041] Through the cooperation of the threaded rod 15 and the adsorption rod 16, the precise positioning of the filter plate 4 is achieved, ensuring that when the pulling plate trolley 1 moves, the filter plate 4 can move smoothly and accurately, reducing the deviation and vibration during the movement.

[0042] The fixed guide frame 7 and the movable guide frame 8 are movably connected by two groups of telescopic rods 11, and both ends of the lower group of telescopic rods 11 are rotatably connected by a rotating rod 10.

[0043] A spring is provided at the inner end of the through hole 19, and the adsorption rod 16 slides left and right along the through hole 19.

[0044] The setting of the spring provides elastic support for the adsorption rod 16, ensuring the smooth sliding of the adsorption rod 16 in the through hole 19. At the same time, the spring can absorb part of the impact and protect the structure from damage.

[0045] The upper end of the pulling plate trolley 1 is provided with a left turning rod 5 and a right turning rod 6, and the lower ends of the fixed guide frame 7 and the movable guide frame 8 are provided with slide rails.

[0046] The cooperation of the left turning rod 5 and the right turning rod 6 with the slide rail ensures the smooth and linear movement of the pulling plate trolley 1 when moving the filter plate 4, improving the stability and safety of the operation.

[0048] The cooperation of the left turning rod 5 and the right turning rod 6 with the slide rail ensures the smooth and linear movement of the pulling plate trolley 1 when moving the filter plate 4, improving the stability and safety of the operation.

[0049] When this application is in use: when it is necessary to move each group of filter plates 4 with different quantities simultaneously, first rotate the left threaded cylinder 17 and the right threaded cylinder 18, and at the same time adjust the distance between the movable guide frame 8 and the fixed guide frame 7 by the telescopic rotation of the two groups of telescopic rods 11. When the left threaded cylinder 17 rotates, the telescopic rod 11 expands and contracts, and when the right threaded cylinder 18 rotates, it pushes the adsorption rod 16 to be fixed at the outer end of the linkage handle 2 through the through hole 19, ensuring that under the adjustment of the moving distance between the movable guide frame 8 and the fixed guide frame 7, it can ensure that the left turning rod 5 on the pulling plate trolley 1 slides along the slide rails at the lower ends of the movable guide frame 8 and the fixed guide frame 7, ensuring the synchronous pushing of each group of filter plates 4 with different quantities;

[0050] When the movable guiding frame 8 and the fixed guiding frame 7 move simultaneously, the slide rail at the lower end can ensure overall stability. Through the linkage between the covering groove 13 and the rotating plate 12, it rotates under the connection of the ruler spring, so that no matter how the telescopic rod 11 at the lower end rotates through the rotating rod 10, the stability of the slide rail can be ensured; through the linkage of the movable guiding frame 8 and the fixed guiding frame 7, the pull plate trolley 1 can quickly unhook under each group of filter plates 4 except the last group.
