Description

Technical Field

[0001] This utility model relates to the field of crystallization reactor technology, specifically to a citric acid monohydrate crystallization reactor. Background Technology

[0002] Citric acid monohydrate is a common organic acid that appears as colorless crystals or white granules. It is easily soluble in water, and the solution is acidic. It is the hydrated form of citric acid and has a sour taste. It is widely used in the food, beverage, pharmaceutical, and cosmetic industries.

[0003] In the production process of citric acid monohydrate, the solution needs to be injected into the crystallization vessel and filtered, heat exchanged and cooled to form crystals of the citric acid monohydrate component in the solution. After long-term use of the crystallization vessel, crystals are easily attached to the surface of the inner coil. Therefore, the inner coil needs to be maintained and cleaned regularly. However, the inner coils inside the existing crystallization vessels are fixed inside the crystallization vessel with bolts, which makes it extremely inconvenient to maintain and clean the inner coils. Utility Model Content

It solves the problem that the internal coils of existing crystallizing reactors are fixed inside the reactor with bolts, making it extremely inconvenient to maintain and clean the internal coils.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a citric acid monohydrate crystallization vessel, comprising a crystallization vessel body, wherein an internal coil mounting mechanism is provided inside the crystallization vessel body;

[0006] The inner coil installation mechanism includes a connecting rod fixedly installed on the inner surface of the crystallizer body. A connecting plate is fixedly installed at one end of the connecting rod. A U-shaped support sleeve is fixedly installed on the surface of the connecting plate. A fixing plate is fixedly installed on the surface of the U-shaped support sleeve. A sleeve is fixedly installed on the surface of the fixing plate. A top spring is fixedly installed inside the sleeve. A top rod penetrating to the outer surface of the sleeve is fixedly installed at one end of the top spring. A top block located inside the U-shaped support sleeve is fixedly installed at the bottom of the top rod.

[0007] Furthermore, the left side of the U-shaped support sleeve is higher than the right side, the higher side surface of the U-shaped support sleeve is fixedly connected to the surface of the connecting plate, and the fixing plate is fixedly installed on the higher side surface of the U-shaped support sleeve.

[0008] The advantage of adopting the above-mentioned further solution is that it makes it easier to place the inner coil inside the U-shaped support sleeve.

[0009] Furthermore, the curvature of the bottom inner side of the U-shaped support sleeve is adapted to the surface curvature of the inner coil, and the width of the inner side of the U-shaped support sleeve is adapted to the diameter of the inner coil.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the gap between the inner coil and the U-shaped support sleeve is smaller after the inner coil is placed in the U-shaped support sleeve, which helps to prevent the inner coil from shaking inside the U-shaped support sleeve.

[0011] Furthermore, the width of the top block is adapted to the inner width of the U-shaped support sleeve, and an arc-shaped groove is provided on the lower surface of the top block, the curvature of which is adapted to the surface curvature of the inner coil.

[0012] The advantage of adopting the above-mentioned further solution is that it facilitates limiting the position above the inner coil.

[0013] Furthermore, the inner surface of the U-shaped support sleeve is provided with two T-shaped grooves, and the side surface of the top block is fixedly equipped with two T-shaped limiting blocks that are engaged with the T-shaped grooves.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the T-slot and T-shaped limiting block help improve the stability of the top block moving within the U-shaped support sleeve.

[0015] Furthermore, a telescopic sleeve is fixedly installed on the bottom surface of the sleeve, and a connecting ring is fixedly installed on the surface of the top rod, with the bottom of the telescopic sleeve being fixedly connected to the connecting ring.

[0016] By setting up a telescopic sleeve, the connection between the sleeve and the push rod can be protected and sealed, which helps to prevent the solution from entering the inside of the sleeve.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0018] This monohydrate citric acid crystallizer features a connecting plate within the crystallizer body, with a U-shaped support sleeve on the connecting plate. The U-shaped support sleeve is equipped with a top spring, a top rod, and a top block. When installing the inner coil, the inner coil can be directly placed inside the U-shaped support sleeve. The top spring and top rod press the top block downwards, using the top block to limit the top of the inner coil, thus completing the installation. This design is convenient and quick to use. Installing and disassembling the inner coil does not require tools to remove the bolts, greatly improving the efficiency of installation and disassembly. It also facilitates maintenance and replacement of the inner coil, solving the problem that existing crystallizers use bolts to fix the inner coil inside, making maintenance and cleaning extremely inconvenient.

[0025] 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.

[0026] Please see Figures 1 to 5This embodiment of a citric acid monohydrate crystallizer includes a crystallizer body 1. An internal coil mounting mechanism is provided inside the crystallizer body 1. The internal coil mounting mechanism includes a connecting rod 2 fixedly mounted on the inner surface of the crystallizer body 1. A connecting plate 3 is fixedly mounted on one end of the connecting rod 2. A U-shaped support sleeve 4 is fixedly mounted on the surface of the connecting plate 3. A fixing plate 5 is fixedly mounted on the surface of the U-shaped support sleeve 4. The left side of the U-shaped support sleeve 4 is higher than the right side, and the higher side surface of the U-shaped support sleeve 4 is flush with the surface of the connecting plate 3. The surfaces are fixedly connected, and the fixing plate 5 is fixedly installed on the higher side of the U-shaped support sleeve 4 to facilitate the insertion of the inner coil into the U-shaped support sleeve 4. The curvature of the bottom of the inner side of the U-shaped support sleeve 4 matches the curvature of the surface of the inner coil, and the width of the inner side of the U-shaped support sleeve 4 matches the diameter of the inner coil. This results in a smaller gap between the inner coil and the U-shaped support sleeve 4 after the inner coil is inserted, which helps prevent the inner coil from shaking inside the U-shaped support sleeve 4. A sleeve 6 is fixedly installed on the surface of the fixing plate 5. An internally fixed top spring 7 is installed, and a top rod 8 extending through the outer surface of the sleeve 6 is fixedly installed at one end of the top spring 7. A top block 9 located inside the U-shaped support sleeve 4 is fixedly installed at the bottom of the top rod 8. The width of the top block 9 is adapted to the inner width of the U-shaped support sleeve 4. An arc-shaped groove 10 is formed on the lower surface of the top block 9. The arc of the arc-shaped groove 10 is adapted to the surface arc of the inner coil, which facilitates the limitation of the upper part of the inner coil. Two T-shaped grooves 11 are formed on the inner surface of the U-shaped support sleeve 4. The side surface of the top block 9 is fixed. Two T-shaped limiting blocks 12 are installed and snapped into the T-shaped groove 11. The T-shaped groove 11 and the T-shaped limiting blocks 12 help to improve the stability of the top block 9 moving in the U-shaped support sleeve 4. A telescopic sleeve 13 is fixedly installed on the bottom surface of the sleeve 6, and a connecting ring 14 is fixedly installed on the surface of the top rod 8. The bottom of the telescopic sleeve 13 is fixedly connected to the connecting ring 14. By setting the telescopic sleeve 13, the connection between the sleeve 6 and the top rod 8 can be protected and sealed, which helps to prevent the solution from entering the inside of the sleeve 6.

[0027] The working principle of the above embodiments is as follows:

[0028] In use, move the top block 9 upward. At this time, the top rod 8 retracts into the sleeve 6 and compresses the top spring 7. Then, put the inner coil into the inside of the U-shaped support sleeve 4 so that the inner coil contacts the bottom of the inner side of the U-shaped support sleeve 4. Then release the top block 9. At this time, the top spring 7 loses its restraint and pushes the top rod 8 out of the sleeve 6. Then, the top rod 8 pushes the top block 9 downward along the T-shaped groove 11 until the arc groove 10 on the top block 9 contacts the surface of the inner coil. Then, the inner coil can be installed in the U-shaped support sleeve 4. While the top rod 8 extends and retracts, the telescopic sleeve 13 extends and retracts with the top rod 8.
