Description

Technical Field

[0001] This utility model relates to the field of filter presses, and in particular to a filter plate assembly for a filter press. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a material, causing the liquid to permeate out. The filter plate is the core filtration component of the filter press, its function being to create an intermediate storage space for the filter cake. The material, form, and quality of the filter plate directly affect the overall filtration performance of the machine.

[0003] Currently, when using filter plates on filter presses, the circular water injection holes in the middle of the filter plates are often blocked by material. The blocked material creates bias pressure, which causes the core plate in the middle of the filter plate to break. As a result, the material can easily enter the core plate, and the entire core plate needs to be replaced, which is inconvenient and costly.

[0004] Therefore, it is necessary to invent a filter plate assembly for a filter press to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a filter plate assembly for a filter press to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filter plate assembly for a filter press, including a filter frame, an intermediate core plate disposed within the filter frame, a water injection hole being formed on the surface of the intermediate core plate, an installation ring being disposed within the water injection hole, an annular energy-absorbing box being connected to the inner wall of the installation ring, grooves being formed on all four outer walls of the installation ring, and springs being connected within the grooves, with a rod being connected to the other end of the spring, the side wall of the rod being set as an inclined surface, slots corresponding to the rod being formed around the water injection hole, and adjustable movable frames being provided on both the left and right sides of the filter frame.

[0007] Preferably, the surface of the mounting ring has a hexagonal disassembly opening.

[0008] Preferably, a sealing ring is provided on the outer side of the mounting ring, and the sealing ring is made of rubber.

[0009] Preferably, the adjustable movable frame includes a rectangular outer cylinder connected to the side wall of the filter frame, a sliding frame connected inside the rectangular outer cylinder, a roller shaft rotatably disposed inside the sliding frame, threaded holes on both the upper and lower sides of the sliding frame, and bolts threaded into the threaded holes, and strip-shaped openings corresponding to the bolts on both the upper and lower sides of the rectangular outer cylinder.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] By using the annular energy-absorbing box to absorb energy from the blocked material, only the annular energy-absorbing box deforms. By rotating the mounting ring, the mounting ring drives the insertion rod to rotate. The inclined surface of the insertion rod presses against the slot, and the friction force causes the insertion rod to retract into the groove. By pulling the mounting ring, the mounting ring and the annular energy-absorbing box can be removed from the water injection hole. This allows the annular energy-absorbing box to be disassembled separately, reducing the high cost of replacing the entire intermediate core board. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides, for example Figure 1-4The filter plate assembly for a filter press shown includes a filter frame 1, an intermediate core plate 2 disposed within the filter frame 1, water injection holes 3 formed on the surface of the intermediate core plate 2, an installation ring 4 disposed within the water injection holes 3, an annular energy-absorbing box 5 connected to the inner wall of the installation ring 4, grooves 6 formed on all four outer walls of the installation ring 4, and springs 7 connected within the grooves 6, with the other end of the springs 7 connected to a rod 8, the side wall of the rod 8 being beveled, and slots corresponding to the rod 8 formed around all four sides of the water injection holes 3. By using the annular energy-absorbing box 5 to absorb energy from the blocked material, only the annular energy-absorbing box 5 deforms. By rotating the mounting ring 4, the mounting ring 4 drives the insertion rod 8 to rotate. The inclined surface of the insertion rod 8 presses against the slot, and the friction force causes the insertion rod 8 to retract into the groove 6. By pulling the mounting ring 4, the mounting ring 4 and the annular energy-absorbing box 5 can be removed from the water injection hole 3. Thus, the annular energy-absorbing box 5 can be disassembled separately, reducing the high cost of replacing the entire intermediate core plate 2. Adjustable movable frames 9 are provided on both the left and right sides of the filter frame 1.

[0019] The surface of the mounting ring 4 has a hexagonal disassembly port 10. By inserting a hexagonal wrench into the hexagonal disassembly port 10 and pulling the mounting ring 4 to rotate, the annular energy-absorbing box 5 can be easily disassembled.

[0020] A sealing ring is provided on the outer side of the mounting ring 4, and the sealing ring is made of rubber, which can easily increase the sealing performance between the mounting ring 4 and the water injection hole 3.

[0021] The adjustable movable frame 9 includes a rectangular outer cylinder 91 connected to the side wall of the filter frame 1. A sliding frame 92 is connected inside the rectangular outer cylinder 91. A roller 93 is rotatably installed inside the sliding frame 92. Threaded holes are opened on both the upper and lower sides of the sliding frame 92, and bolts 94 are threaded into the threaded holes. Slotted openings corresponding to the bolts 94 are opened on both the upper and lower sides of the rectangular outer cylinder 91. By rotating the bolts 94, the bolts 94 are loosened, and the sliding frame 92 is pulled, so that the sliding frame 92 slides inside the rectangular outer cylinder 91. After the roller 93 is adjusted to a suitable position, the bolts 94 are tightened, and it can be installed on filter presses of different sizes.

[0022] Working principle of this utility model:

[0023] By using the annular energy-absorbing box 5 to absorb energy from the clogged material, only the annular energy-absorbing box 5 deforms. By rotating the mounting ring 4, the mounting ring 4 drives the insertion rod 8 to rotate. The inclined surface of the insertion rod 8 presses against the slot, and the friction causes the insertion rod 8 to retract into the groove 6. By pulling the mounting ring 4, the mounting ring 4 and the annular energy-absorbing box 5 can be removed from the water injection hole 3, so that the annular energy-absorbing box 5 can be disassembled separately. By rotating the bolt 94, the bolt 94 is loosened, and the sliding frame 92 is pulled, so that the sliding frame 92 slides in the rectangular outer cylinder 91. After adjusting the roller shaft 93 to the appropriate position, the bolt 94 is tightened, and it can be installed on filter presses of different sizes.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
