Description

Technical Field

[0001] The utility model mainly relates to the technical field of filter presses, and specifically relates to a filter press with an adjustable movable thrust plate. Background Art

[0002] A filter press is a mechanical device that uses filter plates and a thrust plate to apply a certain pressure to the external material to be filtered, so that the liquid seeps out. It is a commonly used solid-liquid separation device. It has been applied to chemical production since the early 18th century and is still widely used in industries such as chemical industry, pharmacy, metallurgy, dye, food, brewing, ceramics, and environmental protection. It has stable performance, convenient operation, safety, and labor saving.

[0003] In the prior art, the thrust plate is generally integrally welded to the sliding beam of the frame. When the equipment completes the filtering, sludge is easily attached between the thrust plate and the filter plate. If the gap between the filter plate and the thrust plate is small, it is not easy to remove the sludge, and the convenience of using the equipment is poor. If the gap distance between the filter plate and the thrust plate is increased, the stroke of the filter plate oil cylinder needs to be increased, resulting in a decrease in the pressure of the filter plate and low working efficiency of the equipment. Summary of the Utility Model

[0004] Aiming at the above problems existing in the prior art, the purpose of the utility model is to provide a filter press with an adjustable movable thrust plate, which can adjust the distance between the filter plate and the thrust plate without changing the stroke of the filter plate oil cylinder.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A filter press with an adjustable movable thrust plate includes a frame. Four sliding beams are arranged on the frame. The sliding beams are grouped in pairs and fixed on two parallel sides of the frame. A chute is formed between any group of sliding beams. A thrust plate oil cylinder is arranged in the chute. The telescopic end of the thrust plate oil cylinder is fixed with a thrust plate. A filter plate oil cylinder is arranged at the starting position of the sliding of the chute. The telescopic end of the filter plate oil cylinder is fixed with a filter plate. A pin sleeve is embedded in any one of the sliding beams. An active pin that fits with the pin sleeve is arranged in the thrust plate.

[0006] Preferably, a slide rail is arranged on the position of any one of the sliding beams away from the chute. Sliders that fit with the slide rail are arranged on both sides of the thrust plate.

[0007] Furthermore, the same sliders are arranged on both sides of the filter plate. Through the structural arrangement of the chute and the sliders, the thrust plate and the filter plate are movably arranged on the sliding beam.

[0008] Preferably, a limit block is arranged at the end position of the sliding of the chute to limit the movement range of the thrust plate along the direction of the chute.

[0009] Preferably, the thrust plate is a hollow plate-like structure. Two pin cylinders are vertically arranged inside the thrust plate. Any one of the pin cylinders is a double-acting cylinder with two telescopic ends. The number of movable pins is four, which are respectively arranged on the four telescopic ends of the two pin cylinders. The movable pins are driven by the pin cylinders to move telescopically along the inner wall of the pin sleeve, so as to clamp and fix the thrust plate between the sliding beams to limit the sliding of the thrust plate.

[0010] Furthermore, the inside of the thrust plate is filled with reinforcing ribs in the horizontal and vertical directions. The reinforcing ribs are located around the movement path of the movable pins, and the internal structure stability of the thrust plate is strengthened by the mutually perpendicular reinforcing ribs.

[0011] Preferably, a hanging rod is inserted along the chute direction on the thrust plate, and jacks matching the hanging rod are formed on the filter plate. The external material to be filtered is fixed between the thrust plate and the filter plate through the hanging rod and the jacks.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The thrust plate is driven by the thrust plate cylinder to move and adjust along the chute direction, and the movement of the thrust plate is limited and fixed by the mutual insertion of the pin sleeve and the movable pins. The distance between the filter plate and the thrust plate can be adjusted without changing the stroke of the filter plate cylinder, and the working efficiency is high and it is easy to use;

[0014] By arranging a number of mutually perpendicular reinforcing ribs around the movement path of the movable pins inside the thrust plate, the structural stability during the pressure filtration process of the thrust plate is improved. And through the cooperation of the hanging rod on the thrust plate and the jacks on the filter plate, the filtering material is located between the filter plate and the thrust plate throughout the pressure filtration process, without the need for manual lifting of the material to be filtered, and the equipment structure is stable, saving time and effort.

[0025] The embodiment of the present invention provides a filter press with an adjustable movable thrust plate, which can adjust the distance between the filter plate and the thrust plate without changing the stroke of the filter plate oil cylinder.

[0026] As Figures 1 to 3 shown, a filter press with an adjustable movable thrust plate includes a frame 1. Four slide beams 11 are arranged on the frame 1. The slide beams 11 are steel pipes. The slide beams 11 are grouped in pairs and fixed at parallel positions on the inner and outer sides of the frame 1. A slide groove 2 is formed between any group of slide beams 11. A thrust plate oil cylinder 5 is arranged in the slide groove 2. The number of the slide grooves 2 and the thrust plate oil cylinders 5 is the same, both being two. The telescopic ends of the two thrust plate oil cylinders 5 are fixedly connected to a thrust plate 3. The other ends of the two thrust plate oil cylinders 5 are fixedly connected to the side wall of the frame 1. A filter plate oil cylinder 6 is arranged at the starting position of the slide of the slide groove 2. The number of the filter plate oil cylinders 6 is four. The telescopic ends of the four filter plate oil cylinders 6 are fixed to the same filter plate 4. The other ends of the four filter plate oil cylinders 6 penetrate through the side wall of the frame 1. A pin sleeve 9 is embedded in any one of the slide beams 11. A movable insert pin 16 that fits with the pin sleeve 9 is arranged in the thrust plate 3.

[0027] A slide rail 12 protruding outward is provided at a position of any one of the slide beams 11 away from the slide groove 2, and sliders 13 are provided on both sides of the thrust plate 3. The connection between the slider 13 and the slide rail 12 is concave so as to slide along the slide rail 12. The same sliders 13 are provided on both sides of the filter plate 4, and a limit block 10 is provided at the sliding end position of the slide groove 2. During the sliding process of the slider 13 along the slide rail 12, the telescopic end of the thrust plate cylinder 5 slides synchronously along the slide groove 2, and the telescopic end of the thrust plate cylinder 5 slides to be close to the limit block 10 to limit the slider 13 from sliding off the rail in the direction of the slide rail 12.

[0028] The thrust plate 3 is a hollow plate-like structure, and two latch cylinders 15 are arranged in the thrust plate 3 along the vertical direction. Any one of the latch cylinders 15 is a bidirectional cylinder with two telescopic ends in opposite directions. The number of the movable latches 16 is four, and they are respectively arranged on the four telescopic ends of the two latch cylinders 15. The inside of the thrust plate 3 is filled with mutually perpendicular reinforcing ribs 14 in the horizontal and vertical directions.
