Abstract
Description
Technical Field
[0001] This utility model relates to the field of taurine processing technology, and in particular to a vertical crude taurine separation device. Background Technology
[0002] Taurine, also known as taurine or 2-aminoethanesulfonic acid, is one of the essential amino acids required by the human body under certain conditions. As a non-protein amino acid, taurine has significant physiological effects on physical performance and a series of unique functions in the cardiovascular system, enhancing physical fitness and relieving fatigue. Taurine also possesses anti-inflammatory, antipyretic, analgesic, anticonvulsant, and blood pressure-lowering effects. Furthermore, it plays a beneficial role in infant brain development, nerve conduction, visual function, and calcium absorption. Therefore, taurine is increasingly gaining broad commercial and social value in food, health products, medicine, and organic synthesis, with rapid market demand growth and promising application prospects.
[0003] Taurine is a white crystalline or powdery substance, readily soluble in water. Its main industrial production methods include the ethanolamine process and the ethylene oxide process. However, regardless of the production process used, current taurine production inevitably involves the concentration and cooling crystallization of taurine aqueous solutions. In existing technologies, the separation of taurine residues is achieved using rotating drums with filter holes. However, if the filter holes are too large, they are ineffective; if they are too small, they are difficult to clean. This results in incomplete filtration and the presence of large amounts of taurine in the filtrate, impacting taurine production costs. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a vertical crude taurine separation device, which features thorough crystal filtration and easy cleaning.
[0005] The technical solution adopted in this utility model is as follows.
[0006] A vertical crude taurine separation device includes a frame, a fixed drum with a first opening at its top, which is vertically fixed on the frame, and a rotating drum vertically disposed inside the fixed drum; the rotating drum has a plurality of liquid ejection holes on its peripheral sidewalls; the rotating drum has a second opening at its top; a first rotating shaft mounting hole is vertically disposed at the center of the bottom surface of the fixed drum, a rotating shaft is mounted on the first rotating shaft mounting hole, and the top of the rotating shaft is connected to the center of the bottom surface of the rotating drum; the rotating shaft is connected to a rotating shaft drive device disposed on the frame.
[0007] The top of the circumferential sidewall of the rotating drum is provided with a drum lip that slopes toward the center of the second opening. The outer circumferential surface of the drum lip has several hooks arranged in a ring along the central axis of the rotating shaft. Several filter cloth sheets are provided inside the rotating drum. Each filter cloth sheet has a hanging ring at its top and each hanging ring is connected to a hook. The height of each filter cloth sheet is greater than the height of the circumferential sidewall of the rotating drum. Several first rolling element mounting seats are arranged in a ring on the inner circumferential side of the top of the circumferential sidewall of the fixed drum. A first rolling element is installed on each first rolling element mounting seat and the first rolling element is in contact with the outer circumferential surface of the circumferential sidewall of the rotating drum. A liquid outlet is provided at the bottom of the fixed drum.
[0008] Its beneficial effects are as follows: The cooled, crystallized crude taurine liquid is placed into a rotating drum, which rotates along its central axis. Taurine crystals in the liquid are blocked by the filter cloth and remain inside the drum. The remaining liquid enters the fixed drum through the discharge hole and flows out through the outlet. Compared to existing technologies that use a rotating drum with filter holes, this method solves the problems of filter holes that are too large to achieve filtration, or too small to be easily cleaned, resulting in incomplete filtration. The filtrate does not contain a large amount of taurine. Since the filter cloth is hung on a hook, it can be easily removed for cleaning. A first rolling element ensures stable drum rotation. The top of the drum's side wall has a lip that slopes towards the center of the second opening, and the filter cloth has operating space while hanging on the hook.

[0010] Using this technical solution, once the filtration inside the drum is complete, the drum can be lifted from the top of the shaft and replaced with another drum to continue solid-liquid separation, thus improving the separation efficiency.
[0011] As a preferred technical solution, a horizontal plate is provided on the frame, and a second rotating shaft through hole is provided directly below the first rotating shaft mounting hole on the horizontal plate, through which the rotating shaft passes.
[0012] This technical solution makes the shaft rotation more stable.
[0013] As a preferred technical solution, the rotating shaft drive device includes a drive motor vertically mounted on a horizontal plate, and a transmission wheel coaxially mounted below the fixed drum on the rotating shaft. The transmission wheel is connected to the power output wheel of the drive motor via a belt; the transmission wheel is positioned above or below the horizontal plate.
[0014] As a preferred technical solution, the liquid outlet is connected to the liquid outlet pipe, and a valve is provided on the liquid outlet pipe.
[0015] This technical solution allows for rapid liquid dispensing.
[0016] As a preferred technical solution, a limiting wheel is coaxially connected to the rotating shaft. The limiting wheel is located on the side of the horizontal plate away from the rotating wheel. Several second rolling element mounting seats are arranged in a ring along the central axis of the rotating shaft between the limiting wheel and the horizontal plate, and between the rotating wheel and the horizontal plate. A second rolling element is installed on each second rolling element mounting seat, and the second rolling element is in contact with the horizontal plate.
[0017] This technical solution makes the shaft rotation more stable.

[0045] The present invention will now be further described in conjunction with the accompanying drawings and embodiments.
[0046] Example 1. As... Figure 1-5 As shown, a vertical crude taurine separation device includes a frame 1, a fixed drum 2 vertically fixed to the frame 1 with a first opening 14 at its top, and a rotating drum 4 vertically disposed inside the fixed drum 2; a plurality of liquid ejection holes 3 are provided on the peripheral side wall 41 of the rotating drum; a second opening 5 is provided at the top of the rotating drum 4; a first rotating shaft mounting hole 6 is vertically provided at the center of the bottom surface 202 of the fixed drum, and a rotating shaft 7 is installed on the first rotating shaft mounting hole 6, with the top end 71 of the rotating shaft connected to the center of the bottom surface 42 of the rotating drum; the rotating shaft 7 is connected to a rotating shaft drive device disposed on the frame 1.
[0047] like Figure 2 The top of the circumferential sidewall 41 of the drum shown is provided with a drum lip 40 that is inclined toward the center of the second opening 5. The drum lip 40 is shaped like a trumpet with the opening facing downwards. Eight hooks 8 are arranged in a ring along the central axis of the rotating shaft 7 on the outer circumferential surface of the drum lip 40. Eight filter cloth sheets 9 are provided inside the drum 4. Each filter cloth sheet 9 has a hanging ring 10 at its top, and each hanging ring 10 is connected to a hook 8.
[0048] The height of each filter cloth sheet 9 is greater than the height of the drum's peripheral sidewall 41. Thus, the bottom end of the filter cloth sheet 9 contacts the top surface of the drum's bottom surface 42.
[0049] like Figure 2 The inner circumferential side surface of the top of the fixed drum 201 has eight first rolling element mounting seats 11 arranged in a ring, and each first rolling element 12 is mounted on the first rolling element mounting seat 11. The first rolling element 12 is in contact with the outer circumferential surface of the drum 2; the bottom end of the fixed drum 2 is provided with a liquid outlet 13. Specifically, as shown... Figure 1 As shown, a liquid outlet 13 is provided at the bottom end of the peripheral side wall 201 of the fixed drum.
[0050] like Figure 1 As shown, a horizontal plate 16 is provided on the frame 1, and a second shaft through hole 17 is provided directly below the first shaft mounting hole 6 on the horizontal plate 16, through which the shaft 7 passes.
[0051] like Figure 1 , Figure 3 As shown, the rotating shaft drive device includes a drive motor 18 vertically mounted on a horizontal plate 16, and a transmission wheel 20 coaxially mounted below the fixed drum 2 on the rotating shaft 7. The transmission wheel 20 is connected to the power output wheel 19 of the drive motor 18 via a belt 21. The transmission wheel 20 is positioned above the horizontal plate 16.
[0052] like Figure 1As shown, the outlet 13 is connected to the outlet pipe 28, and the outlet pipe 28 is equipped with a valve 29. This technical solution allows for rapid liquid dispensing. During operation, a cooled, crystallized taurine solution is fed into the second opening 5 from the taurine liquid delivery hose 31.
[0053] like Figure 1 As shown, a limiting wheel 22 is coaxially connected to the rotating shaft 7, and the limiting wheel 22 is located on the side of the horizontal plate 16 away from the rotating wheel. In this example, the limiting wheel 22 is located on the lower side of the horizontal plate 16.
[0054] like Figure 5 As shown, twenty-four second rolling element mounting seats 23 are arranged in a ring around the central axis of the rotating shaft 7 between the limiting wheel 22 and the horizontal plate 16, and between the rotating wheel and the horizontal plate 16. A second rolling element 24 is mounted on each second rolling element mounting seat 23, and the second rolling element 24 is in contact with the horizontal plate 16.
[0055] like Figure 5 As shown, a first rolling bearing 25 is installed on the second shaft through hole 17, and the shaft 7 passes through the first rolling bearing 25. Figure 4 As shown, a second rolling bearing 26 is installed on the first rotating shaft mounting hole 6, and the rotating shaft 7 passes through the second rolling bearing 26.
[0056] The rotating drum includes a circumferential sidewall 41 and a bottom surface 42. The circumferential sidewall 41 is cylindrical, and the bottom surface 42 is a thin cylindrical plate. The fixed drum includes a circumferential sidewall 201 and a bottom surface 202. The bottom surface 202 is a thin cylindrical plate, and the circumferential sidewall 201 is cylindrical. The opening at the top of the circumferential sidewall 41 is the second opening 5, and the opening at the top of the circumferential sidewall 201 is the first opening 14.
[0057] The central axis of the rotating drum peripheral side wall 41, the central axis of the fixed drum peripheral side wall 201, the central axis of the rotating drum bottom surface 42, the central axis of the fixed drum bottom surface 202, and the central axis of the rotating shaft 7 all pass through a straight line perpendicular to the ground; the bottom end of the fixed drum peripheral side wall 201 is provided with a liquid outlet 13.
[0058] like Figure 4 As shown, the bottom surface 42 of the drum has a downward-facing slot 44. The horizontal cross-section of the slot 44 is quadrilateral. The top end 71 of the rotating shaft is adapted to the quadrilateral and can be inserted into the slot 44. Thus, when the top end 71 of the rotating shaft is inserted into the slot 44, the rotating shaft can drive the drum to rotate. When the drum is lifted, the top end 71 of the rotating shaft can be separated from the slot 44, and the drum can be removed.
[0059] like Figure 4 As shown, a sealing ring 27 is installed on the first shaft mounting hole 6, and the shaft 7 passes through the sealing ring 27.
[0060] Several filtration holes 43 are provided on the bottom surface 42 of the drum. This technical solution results in a fast liquid discharge rate.
[0061] Its beneficial effects are as follows: The cooled and crystallized crude taurine liquid is placed into the rotating drum 4, which rotates along the central axis of the rotating shaft 7. The taurine crystal particles 30 in the crude taurine liquid are blocked by the filter cloth 9 and remain inside the rotating drum 4. The remaining liquid enters the fixed drum 2 through the liquid ejection hole 3 and flows out from the liquid outlet 13. Compared with the existing technology that uses a rotating drum with filter holes, this solves the problems of the filter holes being too large to achieve a filtering effect, and too small to be easy to clean, resulting in incomplete filtration. The filtrate does not contain a large amount of taurine. Since the filter cloth 9 is hung on the hook 8, it can be removed and cleaned at any time, making cleaning quick and easy. A first rolling element 12 is provided, ensuring stable rotation of the rotating drum 4. The top of the side wall 41 of the rotating drum has a drum lip 40 that slopes towards the center of the second opening 5, and the filter cloth 9 has operating space when hung on the hook 8.
[0062] Example 2. (As shown) Figure 10-11 As shown, the difference between this embodiment and Embodiment 1 is that two handles 15 are vertically arranged at the top of the side wall 41 of the drum, and the central axis of the two handles 15 passes through the central axis of the rotating shaft 7. After filtration is completed in the drum 4, the drum 4 can be lifted from the top of the rotating shaft 71 and another drum 4 can be replaced to continue solid-liquid separation, which improves the separation efficiency and enables continuous operation. This solves the problem in the field that efficient solid-liquid separation of crystals is prone to clogging of the overnight pores and is difficult to operate continuously.
[0063] Example 3. (As shown) Figure 12-13 As shown, the difference between this embodiment and embodiment 1 is that the transmission wheel 20 is located on the lower side of the horizontal plate 16, and the limiting wheel 22 is located on the upper side of the horizontal plate 16.
[0064] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
