Description

Technical Field

[0001] This utility model relates to the field of chemical processing technology, specifically a filter press for the production of chemical auxiliaries. Background Technology

[0002] In the processing of tributyl p-acetyl citrate, a filter press is required. Chemical additives are injected into the feed pipe and distributed to each filter chamber via a distribution pipe. Then, the hydraulic cylinder is activated, extending the transverse hydraulic rod. This pushes the baffles on both sides closer together, causing them to move towards one side of the filter frame. The first and second hydraulic rods retract into the receiving groove, bringing the filter frames closer together and the filter chambers contract. The additives are then compressed and filtered through the first and second filter plates. After the filtrate is discharged, a slag plate forms between the first and second filter plates. Once the filtrate inside the bottom chamber is discharged, the lower filter plate is pulled out of the slot, and the transverse hydraulic rod retracts and resets. The first and second hydraulic rods then extend and reset, moving the filter frames on both sides. As the filter frames move, the slag plate moves inside the machine housing. When the slag plate reaches the end of the slot, it falls into the bottom chamber.

[0003] A search revealed that Chinese Patent CN221014662U discloses a filter press for the production of chemical auxiliaries, including a casing. A distribution pipe is fixedly connected to the upper surface of the casing, and a feed pipe is fixedly connected to the upper surface of the distribution pipe. A bottom box is fixedly connected to the bottom of the casing via a bracket, and a discharge pipe is fixedly connected to the side of the bottom box. A slot is provided on the side of the casing, and a lower filter plate is movably inserted into the slot. However, in the prior art, the bottom box is fixedly installed below the filter press. After the lower filter plate is opened, the hydraulic cylinder discharges the slag plate into the bottom box. Since manual removal is required, and the bottom box containing the slag is located below the filter press, it is inconvenient for workers to clean it. Therefore, this paper proposes a filter press for the production of chemical auxiliaries to address the above problems. Utility Model Content

[0016] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses a filter press for the production of chemical auxiliaries. (Refer to...) Figures 1-4A filter press for producing chemical auxiliaries includes a casing 1 and a bottom box 104. A mounting plate 7 is symmetrically fixedly installed at the lower end of the casing 1, and a box plate 6 is symmetrically fixedly installed at the upper end of the bottom box 104. The box plate 6 and the mounting plate 7 are slidably connected. A support rod 3 is fixedly installed at the lower end of the bottom box 104, and a straight wheel 4 is fixedly installed at the lower end of the support rod 3. A pin groove 13 is provided on the outer side of the bottom box 104. The mounting plate 7 is movably connected to the pin groove 13 on the outer side of the bottom box 104 through a limiting mechanism 8. A material hooking mechanism 2 is provided on the inner side of the bottom box 104. This filter press is a known prior art product, and its internal structure has been disclosed; therefore, further details are not provided here. The limiting mechanism 8 includes a mounting shell 801, which is fixedly mounted on the outside of the mounting plate 7. A movable plate 804 is slidably connected to the inside of the mounting shell 801. A limiting pin 802 is fixedly mounted on one side of the movable plate 804, and a pull rod 803 is rotatably connected to the other side of the movable plate 804. A handle 805 is fixedly mounted on the end of the pull rod 803 away from the movable plate 804. A spring 806 is fixedly mounted on the inner wall of the mounting shell 801, and the other end of the spring 806 is fixedly mounted to the movable plate 804. A positioning block 807 is fixedly mounted on the outside of the pull rod 803. A circular hole 809 is opened in the shell wall of the mounting shell 801. One end of the pull rod 803 passes through the circular hole 809, and a through groove 808 is opened in the inner wall of the circular hole 809. By pulling the bottom box 104 out from under the chassis 1, and after the box plate 6 of the bottom box 104 is slidably limited on the mounting plate 7 of the chassis 1, the mechanism utilizes... The limiting mechanism 8 on the mounting plate 7 can be connected to the pin groove 13 on the base box 104 to limit and fix the removed base box 104. Before removing the base box 104, the lever 805 is used to pull the lever 803, so that the lever 803 drives the movable plate 804 to slide, and the limiting pin 802 on the outer side of the movable plate 804 is separated from the currently fixed pin groove 13. During the pulling, the positioning block 807 on the outer wall of the lever 803 contacts the inner wall of the mounting shell 801. After rotation, the positioning block 807 on the lever 803 is pulled out from the through groove 808 on the inner wall of the round hole 809. Then, after rotating a certain position, the positioning block 807 is locked in the round hole 809 of the mounting shell 801. At this time, since the lever 803 is limited and the limiting pin 802 on the movable plate 804 is separated from the pin groove 13, the base box 104 can be pulled out of the limit position after the two operations are completed. The material hooking mechanism 2 includes a material hooking plate 203, which is slidably connected to the inside of the bottom box 104. A pull tube 204 is slidably connected to the inside of the bottom box 104. A connecting seat 202 is fixedly installed on the outside of the material hooking plate 203.

When the bottom box 104 is pulled out from under the machine box 1 and is limited and fixed, the slag inside the bottom box 104 can be cleaned. During the cleaning process, the pull handle 201 drives the material hooking plate 203 to slide inside the bottom box 104 through the pull tube 204, which can easily gather the slag on one side of the inner wall of the bottom box 104 for easy cleaning. During the cleaning process, if a larger shovel tool is used, the pull handle 201 can be used to rotate the pull tube 204 to separate it from the threaded connecting seat 202 and remove it from the bottom box 104.

[0017] Reference Figure 3 A sliding rod 12 is symmetrically fixedly installed on the inner side of the mounting shell 801. The movable plate 804 is slidably connected to the outer side of the sliding rod 12. One end of the sliding rod 12 passes through the middle of the spring 806. Through the sliding rod 12 on the mounting shell 801, the movable plate 804 can slide inside the mounting shell 801. And one end of the sliding rod 12 passes through the spring 806, which can conveniently limit the deformation of the spring 806 to a certain extent.

[0018] Reference Figure 3 A square hole 9 is provided on the inner side of the mounting plate 7. The end of the limiting pin 802 away from the movable plate 804 passes through the square hole 9 and is movably connected to the pin groove 13. Through the square hole 9 on the mounting plate 7, the limiting pin 802 on the limiting mechanism 8 can easily pass through the mounting plate 7 and connect to the pin groove 13 of the bottom box 104. A slider 11 is fixedly installed on the outer side of the box plate 6. A sliding hole 10 is provided on the inner side of the mounting plate 7. The slider 11 and the sliding hole 10 are slidably connected. When the slider 11 on the box plate 6 is limited by sliding at the sliding hole 10 on the mounting plate 7, no matter whether the bottom box 104 moves in or out from under the chassis 1, the limiting pin 802 of the limiting mechanism 8 corresponds to one of the pin grooves 13 on the outside of the bottom box 104, so as to facilitate the limiting and fixing of the bottom box 104.

[0019] Reference Figure 4 The inner wall of the base box 104 is symmetrically provided with sliding grooves 15. The end of the hook plate 203 is slidably connected to the inner side of the sliding groove 15. The connecting seat 202 is fixedly installed with a stud 14 on the side away from the hook plate 203. The end of the pull tube 204 away from the pull handle 201 is threadedly connected to the stud 14. Through the sliding groove 15 on the inner wall of the base box 104, the hook plate 203 can slide stably inside the base box 104. The stud 14 on the connecting seat 202 can be easily disassembled and connected to the pull tube 204 for use.

[0020] Reference Figure 1The upper end of the casing 1 is fixedly installed with a feed pipe 102. A hydraulic cylinder 101 is provided on the outside of the casing 1. A lower filter plate 103 is inserted into the outside of the casing 1. A discharge pipe 105 is provided on the outside of the bottom box 104. Through the feed pipe 102 on the casing 1, chemical additives can be conveniently injected into the casing 1. The additives are distributed to each filter chamber by diversion. After the hydraulic cylinder 101 is operated, the filter frame inside the casing 1 is filtered. The filtrate flows out through the lower filter plate 103 at the bottom of the casing 1 into the bottom box 104 and is then discharged through the discharge pipe 105 on the bottom box 104.

[0021] Working principle: During use, after the filtrate has been filtered and discharged, the lower filter plate 103 at the bottom of the casing 1 is pulled out. Then, the hydraulic cylinder 101 actuates, causing the residue on the filter press frame to fall into the bottom box 104. When cleaning the residue in the bottom box 104, the handle 805 is used to pull the lever 803, causing the lever 803 to slide the movable plate 804. This causes the limiting pin 802 on the outer side of the movable plate 804 to separate from the currently fixed pin groove 13. During this process, the positioning block 807 on the outer wall of the pull rod 803 contacts the inner wall of the mounting shell 801. After rotation, the positioning block 807 on the pull rod 803 is pulled out through the groove 808 on the inner wall of the round hole 809. Then, after rotating a certain position, the positioning block 807 is locked in the round hole 809 of the mounting shell 801. At this time, since the pull rod 803 is limited and the limiting pin 802 and the pin groove 13 on the movable plate 804 are separated, after the two operations are completed, the bottom box 104 can be pulled out of the limit position. After the bottom box 104 is pulled out, during the cleaning process, the pull handle 201 drives the hook plate 203 to slide inside the bottom box 104 through the pull tube 204. This makes it easy to gather the slag on one side of the inner wall of the bottom box 104 for easy cleaning. During the cleaning process, if a larger shovel is used, the pull handle 201 can be used to rotate the pull tube 204 to separate it from the threaded connecting seat 202, and then it can be removed from the bottom box 104.

[0022] 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 claimed utility model.
