Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, specifically to a high-efficiency centrifuge for crystallization separation with anti-accumulation function. Background Technology

[0002] High-efficiency centrifuges for crystallization separation are highly efficient separation devices specifically designed for the solid-liquid separation stage in the crystallization process. Their core function is to quickly and thoroughly separate crystal particles from the mother liquor of crystallization. They are widely used in fields such as pharmaceuticals, fine chemicals, and food, where the purity and appearance of crystallized products are strictly required.

[0003] Most existing centrifuges do not have anti-accumulation devices, which means that during the centrifugation process, the crystal particles may clog the filter holes on the separation cylinder under the action of centrifugal force, resulting in the failure of solid-liquid separation. At the same time, the inner wall of the centrifuge shell needs to be manually cleaned by staff after crystallization, which not only increases the workload but also makes it easy for crystal mother liquor to remain, affecting the results of the next crystallization separation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-efficiency centrifuge for crystallization separation with anti-accumulation function, which has the advantages of effectively preventing crystal accumulation and convenient centrifuge cleaning, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a high-efficiency centrifuge for crystallization separation with anti-accumulation function, including a worktable, multiple support rods fixedly installed on the lower end face of the worktable, a base fixedly installed on the lower end face of the multiple support rods, a collection box slidably connected to the upper end face of the base, a transparent glass plate fixedly installed on the front end face of the collection box, a centrifuge shell fixedly installed on the upper end face of the worktable, two lock bodies fixedly installed on the surface of the centrifuge shell, a top cover mechanism snapped onto the upper end face of the centrifuge shell, two anti-accumulation mechanisms fixedly installed on the lower end face of the top cover mechanism, a drive mechanism fixedly installed on the inner bottom surface of the centrifuge shell, a separation cylinder mechanism snapped onto the surface of the drive mechanism, and two liquid outlets opened on the lower end face of the centrifuge shell.

[0006] As a preferred embodiment of the present invention, the top cover mechanism includes a first sealing cover, two lock heads are fixedly installed on the surface of the first sealing cover, and a sealing ring is fixedly installed on the lower end face of the first sealing cover.

[0007] As a preferred technical solution of this utility model, a second sealing cover is fixedly installed on the lower end face of the first sealing cover, a sealing block is fixedly installed on the lower end face of the second sealing cover, and a first rotating shaft is rotatably installed on the lower end face of the sealing block.

[0008] As a preferred technical solution of this utility model, the anti-accumulation mechanism includes a mechanism shell, a plurality of reset springs are fixedly installed inside the mechanism shell, a limit plate is fixedly installed on one side of the plurality of reset springs, a first connecting block is fixedly installed on one side of the limit plate, and a scraper is fixedly installed on one side of the first connecting block.

[0009] As a preferred embodiment of this utility model, the separation cylinder mechanism includes a separation cylinder body, a snap-fit ​​shaft fixedly installed on the bottom surface of the separation cylinder body, multiple filter holes opened on the surface of the separation cylinder body, two No. 2 connecting blocks fixedly installed on the lower end face of the separation cylinder body, a No. 3 connecting block fixedly installed on the lower end face of each of the two No. 2 connecting blocks, a No. 2 rotating shaft fixedly installed on the upper end face of each of the two No. 3 connecting blocks, a cleaning block sleeved on the surface of each of the two No. 2 rotating shafts, and a fixing block snapped onto the upper end face of each of the two No. 2 rotating shafts.

[0010] As a preferred embodiment of the present invention, the driving mechanism includes a protective housing, a drive motor is fixedly installed inside the protective housing, a coupling is fixedly installed at the output end of the drive motor, a No. 3 rotating shaft is fixedly installed on the upper surface of the coupling, and a plurality of limit blocks are fixedly installed on the surface of the No. 3 rotating shaft.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This high-efficiency centrifuge for crystallization separation with anti-accumulation function has an anti-accumulation mechanism installed at the lower end of the top cover mechanism. Under the action of the return spring, one end of the scraper will always be in close contact with the inner wall of the separation cylinder body. When the drive motor drives the separation cylinder mechanism to rotate, the position of the anti-accumulation mechanism is fixed, so that the scraper can continuously scrape off the crystals that are stuck to the inner wall of the separation cylinder body. This prevents the crystals from accumulating on the inner wall of the separation cylinder body due to centrifugal force, causing filter pore blockage and affecting the efficiency of crystallization separation.

[0012] 2. This high-efficiency centrifuge for crystallization separation with anti-accumulation function uses a connecting block and a second rotating shaft installed at the lower end of the separation cylinder body. After the centrifuge is used, the cleaning block can be fitted onto the surface of the second rotating shaft and limited by the fixing block. Then, driven by the drive motor, the cleaning block will rotate along the inner wall of the separator shell to clean the residual crystallization mother liquor on the inner wall of the separator shell. This not only reduces the workload of the staff, but also effectively prevents the crystallization mother liquor from remaining inside the separation cylinder, so as to ensure the crystallization separation effect in the next time.

Detailed Implementation

[0015] 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.

[0016] Please see Figures 1-7 A high-efficiency centrifuge for crystallization separation with anti-accumulation function includes a workbench 1, multiple support rods 2 fixedly installed on the lower end face of the workbench 1, a base 5 fixedly installed on the lower end face of the multiple support rods 2, a collection box 3 slidably connected to the upper end face of the base 5, a transparent glass plate 4 fixedly installed on the front end face of the collection box 3, a centrifuge shell 6 fixedly installed on the upper end face of the workbench 1, two lock bodies 7 fixedly installed on the surface of the centrifuge shell 6, a top cover mechanism 8 snapped onto the upper end face of the centrifuge shell 6, two anti-accumulation mechanisms 9 fixedly installed on the lower end face of the top cover mechanism 8, a drive mechanism 11 fixedly installed on the inner bottom surface of the centrifuge shell 6, a separation cylinder mechanism 10 snapped onto the surface of the drive mechanism 11, and two liquid outlets 12 opened on the lower end face of the centrifuge shell 6. In the above structure, the top cover mechanism 8 seals the centrifuge shell 6 and the separation cylinder mechanism 10, preventing the crystallization liquid from leaking into the separator when the separation cylinder mechanism 10 rotates, thus avoiding resource waste and environmental pollution. During crystallization separation, one end of the anti-accumulation mechanism 9 is pressed against the inner wall of the separation cylinder mechanism 10, so that the inner wall of the separation cylinder mechanism 10 can be scraped when the separation cylinder mechanism 10 rotates, thereby preventing the crystallized solids from accumulating on the inner wall of the separation cylinder mechanism 10, causing blockage and affecting the crystallization separation efficiency. The separated mother liquor is collected into the collection tank 3 through the outlet 12 for convenient later unified treatment. The amount of mother liquor collected in the collection tank 3 can be monitored in real time through the transparent glass plate 4, thereby preventing excessive mother liquor collection and overflow.

[0017] In a preferred embodiment, the top cover mechanism 8 includes a first sealing cover 801, two lock heads 803 are fixedly installed on the surface of the first sealing cover 801, a sealing ring 802 is fixedly installed on the lower end face of the first sealing cover 801, a second sealing cover 804 is fixedly installed on the lower end face of the first sealing cover 801, a sealing block 805 is fixedly installed on the lower end face of the second sealing cover 804, and a first rotating shaft 806 is rotatably installed on the lower end face of the sealing block 805. In the above structure, the top cover mechanism 8 is fixed by the lock head 803 and the lock body 7. The first sealing cover 801 and the sealing ring 802 can seal the centrifuge shell 6 to prevent the separated mother liquor from leaking. The second sealing cover 804 and the sealing block 805 can seal the separation cylinder mechanism 10 to prevent crystals from leaking from the inside of the separation cylinder mechanism 10.

[0018] In a preferred embodiment, the anti-stacking mechanism 9 includes a mechanism housing 901, a plurality of return springs 902 are fixedly installed inside the mechanism housing 901, a limit plate 903 is fixedly installed on one side of the plurality of return springs 902, a first connecting block 904 is fixedly installed on one side of the limit plate 903, and a scraper 905 is fixedly installed on one side of the first connecting block 904. In the above structure, by installing the outer shell 901 of the mechanism at the lower end of the top cover mechanism 8, under the action of the return spring 902, it is ensured that the scraper 905 can always be in close contact with the inner wall of the separation cylinder body 1001 during the rotation of the separation cylinder mechanism 10. Thus, when the separation cylinder mechanism 10 rotates, the scraper 905 can scrape the inner wall of the separation cylinder body 1001, preventing the crystallized particles from accumulating on the inner wall of the separation cylinder body 1001 due to the action of centrifugal force, blocking the filter holes 1003, and affecting the efficiency of crystallization separation.

[0019] In a preferred embodiment, the separating cylinder mechanism 10 includes a separating cylinder body 1001. A snap-fit ​​shaft 1002 is fixedly installed on the bottom inner surface of the separating cylinder body 1001. Multiple filter holes 1003 are formed on the surface of the separating cylinder body 1001. Two secondary connecting blocks 1004 are fixedly installed on the lower end face of the separating cylinder body 1001. A tertiary connecting block 1005 is fixedly installed on the lower end face of each of the two secondary connecting blocks 1004. A secondary rotating shaft 100 is fixedly installed on the upper end face of each of the two tertiary connecting blocks 1005. 6. Cleaning blocks 1007 are fitted onto the surfaces of both No. 2 rotating shafts 1006, and fixing blocks 1008 are snapped onto the upper surfaces of both No. 2 rotating shafts 1006. The drive mechanism 11 includes a protective housing 1101. A drive motor 1102 is fixedly installed inside the protective housing 1101. A coupling 1103 is fixedly installed at the output end of the drive motor 1102. A No. 3 rotating shaft 1104 is fixedly installed on the upper surface of the coupling 1103. Multiple limit blocks 1105 are fixedly installed on the surface of the No. 3 rotating shaft 1104. In the above structure, the drive motor 1102 drives the third rotating shaft 1104 to rotate, thereby driving the separation cylinder body 1001 to rotate. The crystallizing liquid in the separation cylinder body 1001 completes solid-liquid separation under the action of centrifugal force and filter holes 1003. After the crystallization separation is completed, a cleaning block 1007 can be sleeved on the surface of the second rotating shaft 1006. One side of the cleaning block 1007 will be in close contact with the inner wall of the centrifuge shell 6. Thus, when the separation cylinder body 1001 rotates, the cleaning block 1007 can continuously clean the inner wall of the separation cylinder body 1001, effectively avoiding the presence of crystallization mother liquor residue on the inner wall of the separation cylinder body 1001, which would affect the next crystallization separation.

[0020] Working principle: The separation cylinder mechanism 10 is sleeved onto the surface of the third rotating shaft 1104. The solid-liquid mixture to be separated is then filled into the separation cylinder body 1001. The top cover mechanism 8 is then snapped onto the upper end of the centrifuge housing 6. The top cover mechanism 8 is fixed in place using the lock head 803 and lock body 7. The first sealing cover 801, in conjunction with the sealing ring 802, seals the centrifuge housing 6 to prevent leakage of the separated mother liquor. The second sealing cover 804, in conjunction with the sealing block 805, seals the separation cylinder mechanism 10 to prevent crystals from leaking from inside the separation cylinder mechanism 10. Then, the drive motor 1102 is started, causing the separation cylinder body 1001 to rotate, thus completing the crystallization separation under centrifugal force. As the separation cylinder body 1001 rotates, the scraper 905 returns to its original position. Under the action of spring 902, it will always be in close contact with the inner wall of the separation cylinder body 1001, so that the scraper 905 can scrape the inner wall of the separation cylinder body 1001, thereby preventing the crystallized solids from sticking to the inner wall of the separation cylinder body 1001 and clogging the filter holes 1003, which would reduce the crystallization separation efficiency. The separated liquid will be collected into the collection box 3 through the liquid outlet 12 for later processing. After the crystallization separation is completed, the cleaning block 1007 is sleeved on the surface of the second rotating shaft 1006 and limited by the fixing block 1008, so that the cleaning block 1007 can rotate with the separation cylinder body 1001, thereby continuously cleaning the inner wall of the centrifuge shell 6, thus preventing the crystallization mother liquor from remaining on the inner wall of the centrifuge shell 6 and affecting the next crystallization separation operation.
