Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically a filter plate structure for a filter press. Background Technology

[0002] A filter press is a device used for solid-liquid separation, widely used in chemical, metallurgical, pharmaceutical, food, and environmental protection fields. The filter press applies pressure to a suspension using mechanical force and a hydraulic system, forcing the liquid through a filter screen on a filter plate while retaining solid particles, thus achieving solid-liquid separation. In existing filter presses, the filter plate structure typically involves arranging several filter plates and using a hydraulic system to press them together. However, after a period of use, the filter plates need to be loosened to clean the solid particles. Since there are many filter plates, this requires separating each plate individually after loosening, making cleaning quite cumbersome. Utility Model Content

[0003] The purpose of this invention is to provide a filter plate structure for a filter press to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A filter plate structure for a filter press includes several filter plate bodies, a fixed plate, a pressure plate, and two telescopic components;

[0006] The pressure plate is located on one side of the fixed plate;

[0007] Several filter plate bodies are disposed between the fixed plate and the pressure plate, and plug-in blocks are fixedly connected to both sides of the filter plate body.

[0008] Two telescopic components are respectively arranged on both sides of the pressure plate. The telescopic components include two X-shaped frames one and several X-shaped frames two. The several X-shaped frames two are all located between two X-shaped frames one. The ends of two adjacent X-shaped frames two are rotatably connected by a shaft. The two ends of X-shaped frames one are rotatably connected to the ends of adjacent X-shaped frames two by a shaft. Both X-shaped frames one and X-shaped frames two are rotatably connected by a connecting shaft. A U-shaped frame is provided on one side of X-shaped frame two and is slidably connected to the side of the adjacent plug block. The side of the U-shaped frame is fixedly connected to the end of the adjacent X-shaped frame two.

[0009] Furthermore, each of the two telescopic components is provided with a limit rod on the side away from each other, and a T-shaped groove is provided on the opposite surface of each of the two limit rods. A sliding block is fixedly connected to the end of the connecting shaft and slidably connected to the inner surface of the adjacent T-shaped groove.

[0010] Furthermore, the bottom of the inner side of the T-shaped groove is slidably connected to several pressing blocks.

[0011] Furthermore, both the top of the extrusion block and the bottom of the sliding block are provided with inclined surfaces, and the inclined surfaces of the extrusion block and the sliding block abut against each other.

[0012] Preferably, an L-shaped plate is provided on the side of the limiting rod away from the telescopic component, and the bottom surfaces of several extrusion blocks are fixedly connected to the bottom of the L-shaped plate. A fixing rod is fixedly connected to the side of the limiting rod away from the telescopic component, and three positioning screws are rotatably connected to the fixing rod. Three abutment grooves are opened on the side of the L-shaped plate corresponding to the positioning screws, and an abutment block that is slidably connected to the inner side of the adjacent abutment groove is screwed to the bottom of the positioning screw.

[0013] Furthermore, the fixed plate and the pressure plate are each fixedly connected to two fixed seats on their opposite sides. The side of the fixed seat is fixedly connected to a connecting frame at one end of the X-shaped frame. The two ends of the X-shaped frame away from the second X-shaped frame are screwed together with connecting screws. The end of the connecting screw is rotatably connected to a round block that is slidably connected to the inner side of the adjacent connecting frame.

[0014] Furthermore, the diameter of the circular block is smaller than the diameter of the connecting screw.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By sliding the U-shaped frame and the side of the plug-in block, the fixed plate can be connected to the filter press frame, and the output end of the hydraulic rod of the filter press is connected to the pressure plate drive. The hydraulic rod squeezes several filter plate bodies through the pressure plate, so that the filter plate bodies are closely arranged. When it is necessary to clean the inside of the filter plate body, the pressure plate can be moved away from the filter plate body by the hydraulic rod of the filter press. By extending the telescopic component, the U-shaped frame can drive the adjacent plug-in block to move, so that the filter plate bodies are moved away from each other, and thus a certain gap is opened between the filter plate bodies at one time. The filter plate bodies can be separated from each other relatively quickly, which is convenient for cleaning the inside of the filter plate bodies. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1-4 In this embodiment of the utility model, a filter plate structure of a filter press includes several filter plate bodies 1, a fixing plate 2, a pressure plate 3, and two telescopic components 5.

[0026] A pressure plate 3 is disposed on one side of a fixed plate 2. Several filter plate bodies 1 are disposed between the fixed plate 2 and the pressure plate 3. Insertion blocks 11 are fixedly connected to both sides of each filter plate body 1. Two telescopic components 5 are disposed on both sides of the pressure plate 3. Several filter plate bodies 1, the fixed plate 2, and the pressure plate 3 are all located between the two telescopic components 5. The fixed plate 2 corresponds to the ends of the two telescopic components 5. Each telescopic component 5 includes two X-shaped frames 51 and several X-shaped frames 52. Several X-shaped frames 52 are located between the two X-shaped frames 51. The ends of two adjacent X-shaped frames 52 are connected. The two ends of X-shaped frame 1 51 are rotatably connected to the ends of adjacent X-shaped frame 2 52 via shafts. Several X-shaped frames 2 52 are connected end to end, and both X-shaped frames 1 51 are connected to adjacent X-shaped frames 2 52. Thus, the two X-shaped frames 1 51 and several X-shaped frames 2 52 form a telescopic assembly 5. Both X-shaped frames 1 51 and X-shaped frames 2 52 are rotatably connected to a connecting shaft 53. A U-shaped frame 55 is provided on one side of X-shaped frame 2 52 and is slidably connected to the side of the adjacent plug-in block 11. The side of the U-shaped frame 55 is fixedly connected to the end of the adjacent X-shaped frame 2 52.

[0027] Specifically, the fixing plate 2 can be fixed on the frame of the filter press and the hydraulic rod output end of the filter press is connected to the pressure plate 3. When the filter plate body 1 is inserted from top to bottom between the fixing plate 2 and the pressure plate 3 to connect the filter plate body 1 to the filter press, the insertion block 11 can be inserted into the adjacent U-shaped frame 55 to facilitate the combination of the filter plate body 1 and the telescopic component 5. Then, the pressure plate 3 can be squeezed by the hydraulic rod of the filter press, and the fixing plate 2 can limit and abut against several filter plate bodies 1, so that the pressure plate 3 squeezes several filter plate bodies 1 onto the fixing plate 2, thereby arranging several filter plate bodies 1 tightly between the fixing plate 2 and the pressure plate 3.

[0028] When it is necessary to clean the inside of the filter plate body 1, the pressure plate 3 can be moved away from the filter plate body 1 by the hydraulic rod of the filter press. By extending the telescopic component 5, the X-shaped frame 1 51 and the X-shaped frame 2 52 can rotate simultaneously with the connecting shaft 53 on them, so that the two X-shaped frames 1 51 and several X-shaped frames 2 52 can extend synchronously. The X-shaped frames 1 51 and X-shaped frames 2 52 can drive the U-shaped frame 55 to move through the connecting shaft 53. The U-shaped frame 55 can drive the adjacent plug-in block 11 to move, so that several filter plate bodies 1 are moved away from each other, thereby creating a certain gap between several filter plate bodies 1. This allows for relatively quick separation of several filter plate bodies 1, making it easier to clean the inside of the filter plate body 1.

[0029] Example 1

[0030] like Figure 2-4 As shown, in this embodiment, two fixing seats 6 are fixedly connected to the back of both the fixing plate 2 and the pressure plate 3. A connecting frame 61 is fixedly connected to the side of the fixing seat 6 corresponding to the end of the X-shaped frame 51. Both ends of the X-shaped frame 51 away from the X-shaped frame 52 are screwed together with connecting screw rods 56. A circular block 57 is rotatably connected to the end of the connecting screw rod 56 and is slidably connected to the inner side of the adjacent connecting frame 61. The circular block 57 can be connected to the end of the X-shaped frame 51 through the connecting screw rod 56. The diameter of the circular block 57 is smaller than the diameter of the connecting screw rod 56.

[0031] In practical implementation, when the hydraulic rod of the filter press drives the pressure plate 3 to move, since the fixing plate 2 is fixed to the frame of the filter press, the fixing plate 2 can position the two fixing seats 6 and the two connecting frames 61 on it. The connecting frame 61 can position one end of the X-shaped frame 51 through the round block 57, thereby positioning one end of the telescopic component 5. The pressure plate 3 can drive the two fixing seats 6 and the two connecting frames 61 on it to move. The connecting frame 61 can drive the round block 57 inside it to move, thereby pulling the end of the other X-shaped frame 51. This allows the telescopic assembly 5 to extend as a whole, making it easier to pull apart several filter plate bodies 1, separate the fixing plate 2 from the adjacent filter plate body 1, and separate the pressure plate 3 from the adjacent filter plate body 1, facilitating the cleaning of the filter plate body 1. At the same time, the connecting screw 56 can be rotated relative to the X-shaped frame 51, causing the connecting screw 56 to disengage from the X-shaped frame 51. Then, the round block 57 can be pulled out from the end of the X-shaped frame 51, thereby separating the connecting frame 61 from the two adjacent round blocks 57, facilitating the disassembly and assembly of the fixing seat 6 and the telescopic assembly 5.

[0032] like Figure 3 and Figure 5 As shown, in this embodiment, each of the two telescopic components 5 is provided with a limit rod 4 on the side away from each other, and each of the two limit rods 4 has a T-shaped groove 41 on the opposite side. The end of the connecting shaft 53 is fixedly connected with a sliding block 54 that is slidably connected to the inner side of the adjacent T-shaped groove 41. The sliding block 54 can slide along the inside of the T-shaped groove 41.

[0033] In practice, the limiting rod 4 can be fixed on the frame of the filter press. The limiting rod 4 can be fixed by the frame. The limiting rod 4 can restrict the movement direction of the sliding block 54 through the T-groove 41 and support the sliding block 54. At the same time, it can restrict the rotation of the sliding block 54. In this way, the sliding block 54 can maintain the position and angle of the U-shaped frame 55 through the connecting shaft 53.

[0034] Example 2

[0035] Based on Example 1, such as Figure 5-6As shown, in this embodiment, several pressing blocks 47 are slidably connected to several sliding blocks 54 at the bottom of the inner side of the T-shaped groove 41. The top of the pressing block 47 and the bottom of the sliding block 54 are both provided with inclined surfaces, and the inclined surfaces of the pressing block 47 and the sliding block 54 abut against each other. The top of the pressing block 47 is provided with an inclined surface on one side of the fixed plate 2. An L-shaped plate 42 is provided on the side of the limiting rod 4 away from the telescopic component 5. The bottom surfaces of several pressing blocks 47 are fixedly connected to the bottom of the L-shaped plate 42. A fixed rod 43 is fixedly connected to the side of the limiting rod 4 away from the telescopic component 5. Three positioning screws 45 are rotatably connected to the fixed rod 43. Three abutment grooves 44 are opened on the side of the L-shaped plate 42 corresponding to the positioning screws 45. An abutment block 46 is slidably connected to the bottom of the positioning screw 45 and is spun into the inner side of the adjacent abutment groove 44. The top surface of the abutment block 46 contacts the inner top surface of the abutment groove 44.

[0036] In specific implementation, after the pressure plate 3 squeezes several filter plate bodies 1 to make them closely arranged, the positioning screw 45 can be rotated to move the abutment block 46 upward. After the abutment block 46 contacts the top surface of the abutment groove 44, the abutment block 46 can drive the L-shaped plate 42 upward through the abutment groove 44. The L-shaped plate 42 can drive several pressing blocks 47 upward. Under the pressure of the inclined surface of the pressing block 47, the sliding block 54 can be moved towards the fixed plate 2, thereby limiting the sliding block 54. The sliding block 54 can be connected by the connecting shaft 53. The U-shaped frame 55 limits the insertion block 11, thereby providing auxiliary limiting for several filter plate bodies 1, which helps to improve the fixing effect of the filter plate bodies 1. After rotating one positioning screw 45, the remaining positioning screws 45 can be rotated in sequence, causing the remaining abutment blocks 46 to move upward in sequence, thereby further limiting the L-shaped plate 42. The positioning screws 45 can be rotated in reverse in sequence, causing the abutment blocks 46 to move downward in sequence, so that the L-shaped plate 42 and the pressing block 47 can move downward. At this time, the telescopic component 5 can be extended to widen the gap between several filter plate bodies 1.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
