Description

Technical Field

[0001] This utility model relates to the field of filter press technology, and in particular to a filter press that facilitates filter plate replacement. Background Technology

[0002] A filter press is a device mainly used for solid-liquid separation of filtrate from settled sludge. The filter press mainly includes a frame, a filter frame mounted on the frame, and a hydraulic system mounted on the frame. The filter frame is slidably connected to the frame, and a filter plate and filter cloth are fixed inside the filter frame. The filter cloth and filter plate are detachably connected. The filter plate has injection holes. When the frame injects filtrate into the injection holes, the filtrate adheres to the filter cloth of the filter plate. When the hydraulic system squeezes the filter frame, the liquid and solid in the filtrate are separated, thus obtaining water that can be discharged.

[0003] Existing filter presses with convenient filter plate replacement suffer from cumbersome, time-consuming, and labor-intensive filter plate replacement processes during installation and use. Traditional filter presses typically use bolted or snap-fit ​​connections to fix the filter plates, requiring tools for disassembly and replacement. This not only complicates the operation but also easily leads to component wear due to frequent disassembly, affecting the equipment's lifespan and negatively impacting user experience. To address these shortcomings, we propose a filter press with convenient filter plate replacement. Utility Model Content

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Example 1, as Figures 1-4 As shown, a filter press that facilitates filter plate replacement includes a base 1. A hydraulic cylinder 14 is fixedly installed on the upper end of the base 1. A pressing plate 2 is detachably connected to one end of the piston rod of the hydraulic cylinder 14. A main beam 17 is also fixedly installed on the upper end of the base 1. A sliding rod 16 is fixedly installed on one side of the main beam 17. A thrust plate 15 is fixedly installed between the two sets of main beams 17. A fixed bracket 5 is fixedly installed on the upper end of the main beam 17. An outer frame 3 is fixedly installed between the two sets of fixed brackets 5. The outer frame 3 has a receiving cavity for accommodating the filter plate 9. The filter plate 9 is installed in the receiving cavity of the outer frame 3.

[0017] Example 2, as Figures 1-4 As shown, a filter press for easy filter plate replacement has three sets of slots 10 on both the left and right sides of the filter plate 9, and three sets of through grooves 6 on both the left and right sides of the outer frame 3. The slots 10 and through grooves 6 are positioned correspondingly. Two sets of fixing rods 7 are fixedly installed on the outer wall of the outer frame 3. A fixing plate 4 is fixedly installed at one end of the fixing rod 7. Two sets of height telescopic rods 13 are fixedly installed on one side of the fixing plate 4. A spring 8 is sleeved on the outer wall of the height telescopic rod 13. One end of the height telescopic rod 13 is detachably connected to the movable plate 12 through a connecting ring. Three sets of insert rods 11 are fixedly installed on one side of the movable plate 12. The positions of the insert rods 11 and the through grooves 6 are one-to-one, and the length of the insert rods 11 is greater than the length of the through grooves 6.

[0018] It should be noted that this utility model is a filter press that facilitates the replacement of filter plates. When using it, when it is necessary to replace the filter plate 9, first press the movable plate 12 inward. The movable plate 12 drives the insertion rod 11 to move inward. The spring 8 is always in a compressed state. Continue to compress the spring 8 sleeved on the outer wall of the height telescopic rod 13. Pull the movable plate 12 outward so that the insertion rod 11 exits from the slot 10 on the side of the filter plate 9. At this time, the filter plate 9 can be taken out from the receiving cavity of the outer frame 3.

[0019] Then, the new filter plate 9 is placed into the receiving cavity of the outer frame 3. Ensure that the slot 10 on the side of the filter plate 9 corresponds to the through groove 6 on the side of the outer frame 3. Release the movable plate 12. Under the elastic force of the spring 8, the movable plate 12 drives the insertion rod 11 to move outward. The insertion rod 11 passes through the through groove 6 and is inserted into the slot 10 of the filter plate 9, thereby fixing the filter plate 9 in the outer frame 3.

[0020] Next, start the hydraulic cylinder 14. The piston rod of the hydraulic cylinder 14 pushes the pressing plate 2 to move along the slide rod 16 to press the filter plate 9, and then normal filtration can be carried out.

[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
