Description

Technical Field

[0001] This utility model relates to the field of filter press technology, and in particular to a high-efficiency plate and frame filter press for the production of thiodipropionic acid. Background Technology

[0002] The operation of a plate and frame filter press consists of four processes: pressing, feeding, washing (or drying), and cake discharge. In the production of thiodipropionic acid, the feed pump forces a suspension containing thiodipropionic acid and other components into a filter chamber composed of alternating filter plates and frames. As the suspension enters, filter cake gradually forms on the filter cloth until the filter chamber is full. The filtrate passes through the filter cloth and flows along the grooves of the filter plates to the corner channels of the plate and frame, and is finally discharged, thus achieving solid-liquid separation. After filtration, washing water is introduced to wash the filter cake; after washing, compressed air is sometimes introduced to remove any remaining washing liquid. Then, the filter press is opened to remove the filter cake, the filter cloth is cleaned, the plates and frames are re-pressed, and the next working cycle begins.

[0003] Currently, cleaning filter plates requires manual or automated equipment to separate each plate individually and then shake off the filter residue. This process is repetitive, resulting in slow cleaning, reduced performance, slower progress, and decreased usability.

[0004] To address the problems in the existing technology, a high-efficiency plate and frame filter press for the production of thiodipropionic acid is provided. Utility Model Content

Detailed Implementation

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] like Figure 1 As shown, combined with Figure 2-5 This utility model discloses a high-efficiency plate and frame filter press for the production of thiodipropionic acid, including a workbench 1. Limiting plates 11 are provided on both sides of the upper part of the workbench 1, and a cleaning device 12 is provided on one side of the upper surface of the workbench 1. Multiple first filter plates 2, second filter plates 21 and third filter plates 22 are evenly distributed along the length direction inside the two limiting plates 11. A hydraulic cylinder 13 is provided on one side of the workbench 1. The output end of the hydraulic cylinder 13 is connected to a pressure rod 14. One end of the pressure rod 14 is fixedly connected to a pressure block 15. A sliding hole 151 is opened at the lower part of the pressure block 15, and a spreading and closing assembly 3 is connected inside the sliding hole 151.

[0027] In this embodiment, the unfolding assembly 3 includes a pull rod 31, one end of which is fixedly connected to a limiting circular plate 311. A first fastening assembly 32 is provided at the bottom of the first filter plate 2, a second fastening assembly 33 is provided at the bottom of the second filter plate 21, and a third fastening assembly 34 is provided at the bottom of the second filter plate 22. The first fastening assembly 32 includes a long locking block 321, one side of which is fixed to one end of the pull rod 31, and the outer side of one end of the pull rod 31 is slidably engaged inside the sliding hole 151. The hydraulic cylinder 13 is activated to drive the pressure rod 14 to pull the pressure block 15 to one side. The pressure block 15, under force, slides to one side of the pull rod 31 through the sliding hole 151. After sliding a certain distance outside the pull rod 31, one side of the pressure block 15 presses against one side of the limiting circular plate 311. The lengths of the pull rod 31 and the limiting circular plate 311 allow the first filter plate 2 to maintain a distance from the pressure block 15, avoiding interference with the operation of the cleaning device.

[0028] In this embodiment, the upper surface of the long locking block 321 is provided with a locking groove 322, and a locking block 323 is locked inside the locking groove 322. The upper surface of the locking block 323 is fixed to the bottom of the first filter plate 2. The locking groove 322 and the locking block 323 make it easy to disassemble and install the first filter plate 2 during replacement.

[0029] In this embodiment, the lower parts of both sides of the long locking block 323 are fixedly connected to supporting plates 324. Each supporting plate 324 has a limiting hole 325 inside, and each limiting hole 325 has a sliding rod 35 slidably fitted inside. Both ends of the sliding rod 35 are fixed to the inner side walls of the workbench 1. The first fastening assembly 32, the second fastening assembly 33, and the third fastening assembly 34 have the same structure. When the long locking block 231 is subjected to force, it slides to one side outside the sliding rod 35 through the limiting holes 325 on both sides of the supporting plates 324, ensuring stable movement of the long locking block 231 carrying the first filter plate 2.

[0030] In this embodiment, a first telescopic component 36 is fixedly connected to one side of the bottom of the long locking block 321. The first telescopic component 36 includes a first assembly block 361, and a first sliding block 362 is fixedly connected to one side of the first assembly block 361. A second telescopic component 37 is provided at the bottom of the second fastening component 33. The second telescopic component 37 includes a second assembly block 371, and a second sliding block 372 is fixedly connected to one side of the second assembly block 371. A first sliding groove 373 is opened on the other side of the second assembly block 371, and the first sliding block 362 slides within the first sliding groove 373. By extending the lengths of the multiple first telescopic components 36, second telescopic components 37, and third telescopic components 38, the relative lengths of the multiple first filter plates 2, second filter plates 21, and third filter plates 22 are kept consistent. This allows the nozzles on the cleaning device 12 to directly enter the relative space for cleaning, eliminating the need for moving the filter plates before cleaning and improving the cleaning speed.

[0031] In this embodiment, a third telescopic component 38 is provided at the bottom of the third fastening component 34. The third telescopic component 38 includes a third assembly block 381. A third sliding block 382 is fixedly connected to one side of the third assembly block 381, and a second sliding groove 383 is provided on the other side of the third assembly block 381. The plurality of first telescopic components 36, second telescopic components 37, and third telescopic components 38 are arranged in a trapezoidal pattern at equal intervals along the length direction at the bottom of the plurality of first fastening components 32, second fastening components 33, and third fastening components 34. Through the impact force of the unfolding of the plurality of first telescopic components 36, second telescopic components 37, and third telescopic components 38, the filter residue on the plurality of first filter plates 2, second filter plates 21, and third filter plates 22 can be vibrated and fallen off. There is no need for manual or automatic equipment to separate the filter plates one by one and shake off the filter residue, which can speed up the cleaning of the filter plates, improve working performance, increase work progress, and improve practicality.

[0032] In this embodiment, a folding opening 39 is provided in the middle of one side wall of the workbench 1. A third sliding groove 391 is provided on the inner side wall of the folding opening 39, and the third sliding groove 391 is slidably engaged with a third sliding block 382. After the multiple first telescopic components 36, second telescopic components 37, and third telescopic components 38 are retracted, they all retract into the interior of the folding opening 39, which avoids affecting the retraction operation of the multiple first telescopic components 36, second telescopic components 37, and third telescopic components 38.

[0033] The working principle of this utility model is as follows:

[0034] In this invention, when cleaning the filter residue, the hydraulic cylinder 13 is first activated to drive the pressure rod 14 to pull the pressure block 15 to one side. The pressure block 15, under force, slides to one side of the pull rod 31 through the sliding hole 151. After sliding a certain distance outside the pull rod 31, one side of the pressure block 15 presses against one side of the limiting circular plate 311. At this time, the limiting circular plate 311 is pulled to one side of the long locking block 231 under pressure. The long locking block 231, under force, slides to one side of the slide rod 35 through the limiting holes 325 on the bearing plates 324 on both sides. Simultaneously, the long locking block 231 drives the first filter plate 21 to move to one side. The long locking block 231 also drives the first sliding block 362 on the first assembly block 361 to slide inside the first sliding groove 373. After the first sliding block 362 presses against the inner wall of the first sliding groove 373, the impact force of the first sliding block 362 causes the filter residue on the first filter plate 21 to vibrate off. Then, the first sliding block 362 presses against the second assembly block 371, the second fastening assembly 33, and the second filter plate 21 to move to one side (e.g., ...). Figure 4 As shown), by continuously pulling the adjacent filter plates as described above, the filter residue on each plate can be vibrated off. This continues until the third filter plate 32 and the fourth fastening assembly 34 are pulled. During this process, the third sliding block 382 on the third assembly block 381 slides inside the third sliding groove 391, pressing against the inner wall of the third sliding groove 391 (as shown). Figure 5 As shown), at this time, the operation of the hydraulic cylinder 13 is stopped. At the same time, by extending the lengths of the multiple first telescopic components 36, second telescopic components 37 and third telescopic components 3, the relative lengths of the multiple first filter plates 2, second filter plates 21 and third filter plates 22 can be kept consistent. This space allows the nozzles on the cleaning device 12 to directly enter, thereby completing the deployment of the multiple first filter plates 2, second filter plates 21 and third filter plates 22. Then, the nozzles on the cleaning device 12 are activated to clean the deployed multiple first filter plates 2, second filter plates 21 and third filter plates 22.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
