Description

Technical Field

[0001] This utility model relates to the field of calcium gluconate processing technology, and in particular to a calcium gluconate crystallization device. Background Technology

[0002] In existing technologies, the crystallization of calcium gluconate involves using a saturated solution to generate crystals by controlling the temperature and simultaneously evaporating the solvent. Stirring the calcium gluconate solution during crystallization is necessary to promote mass and heat transfer and prevent crystallization from clumping. However, current equipment uses paddle rotation for stirring, which also causes the solution to rotate, affecting crystal growth. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a calcium gluconate crystallization device that enables the saturated solution to exhibit a plug flow during the crystallization process, thereby promoting crystal growth.

[0004] This utility model discloses a calcium gluconate crystallization device, including a base, an annular crystallization groove on the base, the inner wall of the crystallization groove is a hollow structure, and a cooling cavity is formed inside. A cooling medium inlet pipe and a cooling medium outlet pipe are provided on the crystallization groove, and the cooling medium inlet pipe and the cooling medium outlet pipe are both connected to the cooling cavity.

[0005] A power mechanism is fixed on a base at the annular center of the crystallization tank. The power mechanism has an upward-pointing output shaft, and a horizontal crossbar is provided at the end of the output shaft. The crossbar extends to the top of the crystallization tank, and a downward-pointing stirring rod is provided on the crossbar. The lower end of the stirring rod extends into the crystallization tank, and stirring blades are provided on the stirring rod inside the crystallization tank.

Each group of stirring blades is set on both sides of the stirring rod, and there are gaps between adjacent stirring blades in each group. The two groups of stirring blades are alternately arranged from bottom to top.

[0007] The stirring rod has a rectangular horizontal cross-section and a rectangular through hole on the crossbar. The stirring rod is inserted into the rectangular through hole. A positioning block is provided extending outward from the upper end of the stirring rod. A screw hole is provided on the positioning block, and a screw is provided in the screw hole. The lower end of the screw abuts against the crossbar.

[0008] A vertically downward sleeve is provided on the lower surface of the crossbar corresponding to the inner top wall of the crystallization tank. A ball bearing is provided at the lower end of the sleeve. A sliding seat is provided on the ball bearing inside the sleeve. A compression spring is provided inside the sleeve between the sliding seat and the crossbar. The ball bearing abuts against the inner top wall of the crystallization tank. There is a gap between the lower end of the sleeve and the inner top wall of the crystallization tank, and the gap is smaller than the radius of the ball bearing.

[0009] A bushing is provided on the output shaft, and several connecting rods are arranged in an array at intervals between the bushing and the inner outer wall of the crystallization tank.

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] Example 1:

[0018] like Figures 1-5 As shown, this utility model discloses a calcium gluconate crystallization device, including a base 1, an annular crystallization tank 2 is provided on the base 1, the inner wall of the crystallization tank 2 is a hollow structure, and a cooling chamber 12 is formed inside. A cooling medium inlet pipe and a cooling medium outlet pipe are provided on the crystallization tank 2, and the cooling medium inlet pipe and the cooling medium outlet pipe are both connected to the cooling chamber 12.

[0019] A power mechanism 8 is fixed on a base 1 at the annular center of the crystallization tank 2. The power mechanism 8 is provided with a vertically upward output shaft 3. A horizontal crossbar 4 is provided at the end of the output shaft 3. The crossbar 4 extends to the top of the crystallization tank 2. A vertically downward stirring rod 5 is provided on the crossbar 4. The lower end of the stirring rod 5 extends into the crystallization tank 2. A stirring blade 11 is provided on the stirring rod 5 inside the crystallization tank 2.

[0020] A circular crystallization tank 2 is set on the base 1, with the tank opening upwards. A cooling chamber 12 is formed inside the side wall of the crystallization tank 2, connected to a cooling medium inlet pipe and a cooling medium outlet pipe. In actual use, a saturated calcium gluconate solution is added to the crystallization tank 2. The cooling medium inlet and outlet pipes supply cooling medium to the cooling chamber 12 to maintain the required temperature of the crystallization tank 2, gradually lowering the temperature to control the crystallization temperature. The specific temperature control method is existing known technology and will not be elaborated here. A power mechanism 8 is set on the base 1 at the center of the crystallization tank 2. The power mechanism 8 can be a combination of a drive motor and a reducer. An output shaft 3 is set on the reducer, positioned vertically upwards at the center of the crystallization tank 2. A crossbar 4 is set on the output shaft 3, with a stirring rod 5 at the end of the crossbar 4 and stirring blades 11 at the lower end of the stirring rod 5. In practical use, the power mechanism 8 drives the output shaft 3 to rotate, causing the stirring rod 5 at the end of the crossbar 4 to perform circular motion. Since the end of the stirring rod 5 extends into the crystallization tank 2, the stirring blades 11 agitate the saturated solution within the crystallization tank 2, performing slow, circumferential agitation to create a plug flow of the saturated solution. During this plug flow, the solution is uniform, and crystal growth is less prone to clumping, resulting in stable and reliable crystal growth. The stirring blades 11 can be made of a flexible material, such as PTFE, rather than a rigid material. This type of stirring blade effectively reduces shear and ensures stable crystal growth.

[0021] The stirring blade 11 is a long strip-shaped flat plate structure, which is divided into two groups, each group having several pieces. Each group of stirring blades 11 is respectively arranged on both sides of the stirring rod 5, and there is a gap between adjacent stirring blades 11 in each group. The two groups of stirring blades 11 are arranged alternately from bottom to top.

[0022] Two sets of stirring blades 11 are respectively arranged on both sides of the stirring rod 5, that is, on the front and rear sides of the stirring rod 5 in the direction of operation. The stirring blades 11 on the same side are arranged at intervals, and the two sets of stirring blades 11 are arranged alternately from bottom to top. During the process of pushing the saturated solution, the fluctuation of the saturated solution can be effectively reduced, so as to promote the stable growth of crystals.

[0023] The horizontal cross section of the stirring rod 5 is rectangular. A rectangular through hole is provided on the crossbar 4. The stirring rod 5 is inserted into the rectangular through hole. A positioning block 6 is provided extending outward from the upper end of the stirring rod 5. A screw hole is provided on the positioning block 6. A screw rod 7 is provided in the screw hole. The lower end of the screw rod 7 abuts against the crossbar 4.

[0024] The stirring rod 5 is slidably connected to the crossbar 4 via a rectangular through-hole, allowing adjustment of the height of the stirring blade 11 within the crystallization tank 2 to accommodate saturated solutions at different liquid levels. The screw hole on the positioning block 6 engages with the screw 7 for height adjustment. The screw 7 abuts against the crossbar 4, positioning the stirring rod 5 and ensuring stable and reliable stirring. To further enhance stability, a locking nut can be installed on the screw 7. Rotating the locking nut to engage with the positioning block 6 and locking it prevents relative rotation between the screw 7 and the positioning block 6 during operation, thus avoiding any change in the position of the stirring rod 5.

[0025] A vertically downward sleeve 13 is provided on the lower surface of the crossbar 4 corresponding to the inner top wall of the crystallization tank 2. A ball bearing 14 is provided at the lower end of the sleeve 13. A sliding seat 15 is provided on the ball bearing 14 inside the sleeve 13. A compression spring 16 is provided inside the sleeve 13 between the sliding seat 15 and the crossbar 4. The ball bearing 14 abuts against the inner top wall of the crystallization tank 2. There is a gap between the lower end of the sleeve 13 and the inner top wall of the crystallization tank 2, and the gap is smaller than the radius of the ball bearing 14.

[0026] A sleeve 13 is vertically installed downwards in the middle of the crossbar 4. A ball bearing 14, which can be made of steel, is installed inside the sleeve 13. The ball bearing 14 abuts against the inner top wall of the crystallization tank 2. A sliding seat 15 and a compression spring 16 are installed inside the sleeve 13. The compression spring 16 presses the sliding seat 15 downwards, pressing the ball bearing 14 firmly against the inner top wall of the crystallization tank 2. The sliding seat 15 abuts against the ball bearing 14. During the rotation of the crossbar 4, the sleeve 13 restricts the positions of the compression spring 16, the sliding seat 15, and the ball bearing 14, providing support for the middle part of the crossbar 4. During the rotation of the crossbar 4, the ball bearing 14 rolls on the inner top wall of the crystallization tank 2, resulting in low friction and strong support, thus ensuring the stability and reliability of the crossbar 4 and the stirring rod 5 during overall operation and reducing the impact of fluctuations on crystal growth.

[0027] A bushing 9 is provided on the output shaft 3, and a number of connecting rods 10 are arranged in an array between the bushing 9 and the inner outer wall of the crystallization tank 2.

[0028] A bushing 9 is installed on the output shaft 3. The bushing 9 and the output shaft 3 are free to rotate. The bushing 9 is fixedly connected to the crystallization tank 2 by the connecting rod 10, so that the upper end of the output shaft 3 remains stable and the rotation is stable and reliable.
