Description

Technical Field

[0001] The utility model relates to the technical field of pseudo-boehmite production, and more specifically, to a filter press device for pseudo-boehmite production. Background Art

[0002] Pseudo-boehmite is a transitional product from disorder to order, from weak crystalline to crystalline, with uncertain composition and incomplete crystallization. Its crystal structure is similar to that of boehmite, but it has small crystals, poor crystallinity, and thin wrinkled lamellae. It is a new material with great development prospects.

[0003] At present, in order to effectively remove impurities and excess moisture in pseudo-boehmite, thereby improving the purity and quality of the product and ensuring the physical and chemical properties of pseudo-boehmite, a filter press is usually used to separate the solid and liquid, and then the waste liquid is filtered out to retain the filter cake formed by the filter press. However, in actual use, the filter press operation will generate a large pressure, causing the filter cake to stick to the filter plate and be difficult to remove. Currently, gas is usually passed into the filter plate to loosen the filter cake on the surface of the filter element, and then it is collected. However, the loosened filter cake will be blown by the gas, causing some particles to fly away, resulting in material waste. If the output of the airflow is reduced, the filter cake may not fall off completely, requiring extra time and effort to collect it, increasing the workload, and therefore needs to be improved and optimized.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] like Figures 1 to 7 As shown, the utility model provides a filter press device for pseudo-boehmite production, comprising a bracket 1, wherein the bracket 1 has two groups, and the two groups of brackets 1 are fixedly connected by a connecting rod 2, and a cylinder 3 is fixedly installed on the outer wall of the right bracket 1, and the output shaft of the cylinder 3 passes through the bracket 1 and is fixedly connected to a pressing plate 4;

[0032] The filtering mechanism is movably mounted on the outer wall of the connecting rod 2, and one end of the filtering mechanism is fixedly connected to the pressing plate 4;

[0033] A driving mechanism is fixedly mounted on the outer wall of the bracket 1;

[0034] The vibration mechanism is fixedly mounted on one end of the filtering mechanism and contacts one end of the driving mechanism;

[0035] Among them, there are five groups of vibration mechanisms, including a vibration bin 10 fixedly installed at one end of the filtering mechanism, a movable block 11 is movably installed inside the vibration bin 10, an impact head 12 is fixedly installed at one end of the movable block 11, and an extension rod 14 is fixedly installed at the other end. The right side of the movable block 11 and the inner wall of the vibration bin 10 are elastically connected by a spring 13, the extension rod 14 penetrates to the outside of the vibration bin 10, and is fixedly connected to a transmission plate 15, the transmission plate 15 is located inside the driving mechanism, and conflicts with one end of the driving mechanism.

[0036] When it is necessary to perform a filter press operation, the staff first starts the cylinder 3 to make the pressure plate 4 squeeze the filter plate 5. When the pressure is sufficient, the five groups of filter plates 5 are sealed with each other. Then the staff passes the filtered material into the filter plate 5 to make the filter element 6 complete the solid-liquid separation operation. At this time, the liquid is discharged and fixed to form a filter cake, which adheres to the surface of the filter element 6. Then the staff starts the cylinder 3 to reset the pressure plate 4. When the right filter plate 5 is reset by the pressure plate 4, the connecting rod 1 8 inside the storage bin 7 pulls the connecting rod 2 9 to move, further separating the five groups of filter plates 5 from each other. At this time, the transmission block 19 will translate along the output rod 18, and then the staff starts the motor 17 to rotate the output rod 18. The rotation of the output rod 18 drives the transmission block 19 to rotate, and the rotation of the transmission block 19 will squeeze the transmission Plate 15, so that the extension rod 14 drives the movable block 11 to move, and further makes the impact head 12 impact the outer wall of the filter element 6, so that the filter cake is shaken and falls into the collection bin 21. After each impact is completed, the movable block 11 will reset the transmission plate 15 through the elastic potential energy of the spring 13, ensuring that the transmission plate 15 is always in conflict with the transmission block 19. When the filter cake is collected, the staff will pull out the pull rod 27 to make the resistance block 24 retract into the limit bin 23, and then take out the collection bin 21 through the handle 22 to complete the collection. After the collection is completed, the staff will put the collection bin 21 into the fixed shell 20 for reset, and finally release the pull rod 27. At this time, through the elastic potential energy of the spring 26, the resistance block 24 is extended to the front end of the collection bin 21 to complete the fixation of the collection bin 21.

[0037] The output rod 18 is rotated by the operation of the motor 17, and the rotation of the output rod 18 drives the transmission block 19 to rotate, and the rotation of the transmission block 19 squeezes the transmission plate 15, so that the extension rod 14 drives the movable block 11 to move, and further causes the impact head 12 to impact the outer wall of the filter element 6 to shake the filter cake apart. Compared with the traditional device, the device operates the vibration mechanism through the driving mechanism, loosens the filter cake structure, completes the dropping and collection, effectively avoids the scattering and waste of the filter cake, and improves the product output.

[0038] Wherein, a fixing shell 20 is fixedly installed at the bottom of the two sets of brackets 1;

[0041] Among them, there are two groups of fixing mechanisms, including a limit bin 23 fixedly installed on the outer wall of the fixed shell 20, and a stop block 24 is movably installed inside the limit bin 23. One end of the stop block 24 penetrates into the interior of the fixed shell 20, and the other end of the stop block 24 is fixedly connected to an extension rod 25. The extension rod 25 penetrates to the outer wall of the limit bin 23 and is fixedly connected to the pull rod 27. The stop block 24 and the inner wall of the limit bin 23 are elastically connected by a spring 26.

[0042] When the filter cake is collected, the staff pulls out the pull rod 27 to retract the stop block 24 into the limit bin 23, and then takes out the collection bin 21 through the handle 22 to complete the collection. After the collection is completed, the staff puts the collection bin 21 into the fixed shell 20 for reset, and finally releases the pull rod 27. At this time, the elastic potential energy of the spring 26 causes the stop block 24 to extend to the front end of the collection bin 21, thereby completing the fixation of the collection bin 21.

[0043] The filter cake is collected by the collecting bin 21, and then the collecting bin 21 is fixed and disassembled by controlling the pull rod 27. Compared with the traditional device, the device installs the collecting bin 21 through the fixing mechanism, so that the collecting bin 21 can collect materials stably and is easy to take, which reduces the workload of the staff.

[0044] Among them, the filtering mechanism includes a filter plate 5 movably connected to the connecting rod 2, and there are five groups of filter plates 5. The right filter plate 5 is fixedly connected to the pressure plate 4, and the left filter plate 5 is fixedly connected to the bracket 1. The inside of the five groups of filter plates 5 is fixedly installed with a filter element 6, the front end of the filter plate 5 is fixedly installed with a fixed bin 16, and the rear of the filter plate 5 is fixedly opened with a storage bin 7.

[0045] When the right filter plate 5 is reset by the pressing plate 4, the connecting rod 1 8 inside the storage bin 7 pulls the connecting rod 2 9 to move, further separating the five groups of filter plates 5 from each other.

[0046] The driving mechanism includes a motor 17 fixedly mounted on the outer wall of the bracket 1 , an output shaft of the motor 17 is fixedly connected to an output rod 18 , and the output rod 18 is rotatably mounted between the two groups of brackets 1 .

[0047] Among them, the driving mechanism also includes a fixed bin 16 fixedly installed at the front end of the filter plate 5, there are five groups of fixed bins 16, and transmission blocks 19 are rotatably installed inside the five groups of fixed bins 16. There are five groups of transmission blocks 19, and the five groups of transmission blocks 19 are movably connected to the output rod 18, and the transmission blocks 19 and the transmission plate 15 are in conflict with each other.

[0048] When the filter plates 5 are separated, the transmission block 19 will translate along the output rod 18 , and then the staff starts the motor 17 to rotate the output rod 18 . The rotation of the output rod 18 drives the transmission block 19 to rotate, and the rotation of the transmission block 19 will squeeze the transmission plate 15 .

[0049] The collecting mechanism includes a collecting bin 21 movably mounted inside the fixed shell 20 , one end of the collecting bin 21 is fixedly connected to the handle 22 , and the collecting bin 21 is located behind the stop block 24 .

[0050] When the impact head 12 impacts, the filter cake on the surface of the filter element 6 will fall into the collection bin 21 to be collected, and the staff can take the collection bin 21 through the handle 22.

[0051] Among them, a connecting rod 1 8 is rotatably installed inside the storage bin 7, and a connecting rod 2 9 is rotatably installed inside another group of storage bins 7. The connecting rod 1 8 and the connecting rod 2 9 are hinged to each other.

[0052] The working principle and use process of this utility model:

[0053] When it is necessary to perform a filter press operation, the staff first starts the cylinder 3 to make the pressure plate 4 squeeze the filter plate 5. When the pressure is sufficient, the five groups of filter plates 5 are sealed with each other. Then the staff passes the filtered material into the filter plate 5 to make the filter element 6 complete the solid-liquid separation operation. At this time, the liquid is discharged and fixed to form a filter cake, which adheres to the surface of the filter element 6. Then the staff starts the cylinder 3 to reset the pressure plate 4. When the right filter plate 5 is reset by the pressure plate 4, the connecting rod 1 8 inside the storage bin 7 pulls the connecting rod 2 9 to move, further separating the five groups of filter plates 5 from each other. At this time, the transmission block 19 will translate along the output rod 18, and then the staff starts the motor 17 to rotate the output rod 18. The rotation of the output rod 18 drives the transmission block 19 to rotate, and the rotation of the transmission block 19 will squeeze the transmission Plate 15, so that the extension rod 14 drives the movable block 11 to move, and further makes the impact head 12 impact the outer wall of the filter element 6, so that the filter cake is shaken and falls into the collection bin 21. After each impact is completed, the movable block 11 will reset the transmission plate 15 through the elastic potential energy of the spring 13, ensuring that the transmission plate 15 is always in conflict with the transmission block 19. When the filter cake is collected, the staff will pull out the pull rod 27 to make the resistance block 24 retract into the limit bin 23, and then take out the collection bin 21 through the handle 22 to complete the collection. After the collection is completed, the staff will put the collection bin 21 into the fixed shell 20 for reset, and finally release the pull rod 27. At this time, through the elastic potential energy of the spring 26, the resistance block 24 is extended to the front end of the collection bin 21 to complete the fixation of the collection bin 21.
