Description

Technical Field

[0001] The utility model relates to the technical field of mother liquor recovery devices, in particular to a mother liquor recovery device used for the preparation of chemical products. Background Art

[0002] L-phenylalanine is an important amino acid widely used in the food, pharmaceutical and cosmetic industries. During the production process of L-phenylalanine, a large amount of mother liquor is produced. These mother liquors contain unreacted raw materials, by-products and unextracted L-phenylalanine. In order to improve resource utilization and reduce environmental pollution, it is very necessary to recycle these mother liquors.

[0003] When using the existing mother liquor recovery device, L-phenylalanine crystals are usually located inside the condensation box. In order not to affect the crystallization effect, the L-phenylalanine crystals are located inside the crystallization tank. This makes it very cumbersome to remove the L-phenylalanine crystals after each crystallization. Tools are required to shovel out the L-phenylalanine crystals, and a large amount of residue is likely to remain, making it inconvenient to quickly recover the L-phenylalanine crystals. Utility Model Content

[0004] The purpose of the utility model is to provide a mother liquor recovery device for chemical product preparation, so as to solve the problem in the above background technology that the mother liquor recovery device currently used is inconvenient for collecting L-phenylalanine crystals.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a mother liquor recovery device for chemical product preparation, comprising: a filter box and a cooling assembly, wherein mounting blocks are mounted on the inner wall of the filter box, a filter screen is mounted between two sets of the mounting blocks, one side of the filter box is connected to an evaporation box via a pipe and a water pump, a drainage pipe is mounted on the top of the evaporation box, one side of the evaporation box is connected to a fan via an air guide pipe, a heating assembly is mounted on the bottom of the evaporation box, a side of the evaporation box away from the filter box is connected to a condensation box via a pipe and a water pump, and the cooling assembly is mounted on the bottom of the condensation box;

[0006] A crystallization pool is installed inside the condensation box, a telescopic rod is connected through a groove provided on the inner wall of the crystallization pool, and a movable spring is installed in the telescopic rod and the groove provided on the inner wall of the crystallization pool.

[0011] Preferably, a telescopic block is installed on one side of the compression spring, and a clamping block is installed at the top of the telescopic block.

[0012] Preferably, a clamping head is inserted into a groove formed on one side of the clamping block, and a pulling block penetrating through the fixing block is connected to one side of the telescopic block.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: when the mother liquor recovery device for chemical product preparation is in use, the pressing rod can be pushed downward, so that the pressing rod squeezes the rotary block in the groove of the crystallization tank. When the rotary block is squeezed, it will rotate, so that one end of the rotary block no longer squeezes the convex block on one side of the telescopic rod. Then, the telescopic rod will be reset through the movable spring and drive the crystallization tray to move upward through the mounting frame.

[0014] 1. For the mother liquor recovery device for chemical product preparation, after the L-phenylalanine mother liquor crystals are crystallized, it is necessary to collect the L-phenylalanine mother liquor crystals. At this time, the pressing rod can be squeezed, so that the pressing rod drives the rotary block to rotate, and the rotary block no longer squeezes the convex block on one side of the telescopic rod. At this time, the crystallization tray will move upward through the mounting frame and the telescopic rod, so as to conveniently and quickly remove the crystallization tray and collect the L-phenylalanine mother liquor crystals.

[0015] 2. For the mother liquor recovery device for chemical product preparation, when recovering the L-phenylalanine mother liquor, in order to avoid the influence of impurities in the L-phenylalanine mother liquor on the recovery effect, it is necessary to use a filter screen to filter the L-phenylalanine mother liquor.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1 And Figure 2 , the present utility model provides a technical solution: A mother liquor recovery device for the preparation of chemical products, comprising: a filter box 1 and a cooling component 9. The inner wall of the filter box 1 is provided with mounting blocks 2, a filter screen 3 is installed between two groups of mounting blocks 2. One side of the filter box 1 is connected to an evaporation box 4 through a pipeline and a water pump. A drainage pipe 5 is installed on the top of the evaporation box 4. One side of the evaporation box 4 is connected to a fan 6 through a gas guide pipe. A heating component 7 is installed at the bottom of the evaporation box 4. One side of the evaporation box 4 away from the filter box 1 is connected to a condensation box 8 through a pipeline and a water pump. The cooling component 9 is installed at the bottom of the condensation box 8;

[0026] Inside the condensation box 8, a crystallization tank 10 is installed. A telescopic rod 11 is connected through the groove opened on the inner wall of the crystallization tank 10. An active spring 12 is installed between the telescopic rod 11 and the groove opened on the inner wall of the crystallization tank 10. At the bottom of the telescopic rod 11, two sets of mounting brackets 13 are installed. A crystallization tray 14 is connected between the two sets of mounting brackets 13. On one side of the telescopic rod 11, a convex block 15 is installed. At the top of the convex block 15, a rotating block 16 is provided. A reset spring 17 is installed between the rotating block 16 and the groove opened on the inner wall of the crystallization tank 10. At the top of the rotating block 16, a pressing rod 18 passing through the groove of the crystallization tank 10 is provided. The middle of the rotating block 16 is connected to the groove of the crystallization tank 10 through a rotating shaft.

[0027] During specific implementation, for the mother liquor recovery device used for the preparation of chemical products, when it is necessary to take out the L-phenylalanine mother liquor crystals, the pressing rod 18 can be squeezed downward. Both ends of the pressing rod 18 are slidably connected to the groove of the crystallization tank 10 through sliders. When the pressing rod 18 moves downward, it will exert pressure on the rotating block 16 at the bottom. Since the middle of the rotating block 16 is connected to the groove of the crystallization tank 10 through a rotating shaft, when one end of the rotating block 16 is squeezed by the pressing rod 18, the rotating block 16 will rotate, so that the rotating block 16 does not limit the convex block 15 on one side of the telescopic rod 11. Then the telescopic rod 11 will be reset through the active spring 12, causing the telescopic rod 11 to move upward along the crystallization tank 10. On one side of the telescopic rod 11, a mounting bracket 13 is installed, and a crystallization tray 14 is slidably connected between the two sets of mounting brackets 13. When the telescopic rod 11 moves upward, it will drive the crystallization tray 14 to move upward through the mounting bracket 13. When the crystallization tray 14 moves to the top, the crystallization tray 14 can be slidably removed from between the two sets of mounting brackets 13, thus facilitating the rapid collection of the crystals on the crystallization tray 14.

[0028] Conversely, the crystallization tray 14 can be inserted between the two sets of mounting brackets 13, and then the telescopic rod 11 is squeezed downward. When the telescopic rod 11 cannot move downward, the pressing rod 18 can be released, so that the pressing rod 18 does not squeeze one end of the rotating block 16. Then the rotating block 16 will be reset through the reset spring 17. At this time, the rotating block 16 can limit the telescopic rod 11 in the crystallization tank 10 through the convex block 15, thus not affecting the normal crystallization of the L-phenylalanine mother liquor.

[0029] Refer to Figure 2 、 Figure 3 、 Figure 4 And Figure 7 It can be known that during use, according to the usage requirements, the pressing rod 18 can be squeezed, so that the pressing rod 18 drives the rotating block 16 to rotate. At this time, the convex block 15 is not limited by the rotating block 16, and it can be reset through the active spring 12 and drive the crystallization tray 14 to move upward through the mounting bracket 13, thus facilitating the user to quickly collect the L-phenylalanine mother liquor crystals.

[0030] Fixing blocks 19 are installed on both sides of the filter screen 3. Compression springs 20 are installed in the grooves formed in the inner walls of the fixing blocks 19. A telescopic block 21 is installed on one side of the compression spring 20. A clamping block 22 is installed on the top of the telescopic block 21. A clamping head 23 is inserted into the groove formed on one side of the clamping block 22. A pulling block 24 penetrating through the fixing block 19 is connected to one side of the telescopic block 21. The clamping head 23 is inserted into the clamping block 22 through the groove.

[0031] During specific implementation, when the mother liquor recovery device for chemical preparation needs to replace the filter screen 3, the pulling block 24 can be pulled towards one side of the fixing block 19, so that the pulling block 24 drives the telescopic block 21 to extrude the compression spring 20 in the groove of the fixing block 19. The movement of the telescopic block 21 will drive the clamping block 22 on the top to move towards one side, so that the clamping head 23 moves out of the groove of the clamping block 22. Without the clamping head 23 inserted into the groove of the clamping block 22, the filter screen 3 can be slid out of the groove of the mounting block 2 through the fixing block 19, thus facilitating the user to quickly replace the filter screen 3.

[0032] When installing the filter screen 3, only need to push the filter screen 3 into the groove of the mounting block 2. After the filter screen 3 is installed in the groove of the mounting block 2, release the pulling block 24, and the telescopic block 21 will reset through the compression spring 20 and drive the clamping block 22 on the top to move, so that the clamping block 22 is inserted into the clamping head 23 on the inner wall of the mounting block 2. At this time, the filter screen 3 can be quickly fixed, thus facilitating the replacement of the filter screen 3.

[0033] Refer to Figure 2 、 Figure 5 And Figure 6 It can be known that during use, according to the filtering effect of the filter screen 3, the maintenance window on one side of the filtering box 1 can be opened, and then the pulling block 24 is pulled. At this time, the filter screen 3 can be slid out and disassembled from the groove of the mounting block 2 through the fixing block 19, thus facilitating the quick replacement of the filter screen 3 and making the filtering effect of the L-phenylalanine mother liquor better.

[0034] In summary: When the mother liquor recovery device for chemical preparation is in use, the L-phenylalanine mother liquor can be injected into the filtration tank 1. The L-phenylalanine mother liquor can be filtered through the filter screen 3 in the filtration tank 1. After filtration, the L-phenylalanine mother liquor is drained into the evaporation tank 4 through a pipeline and a water pump. A heating component 7 is installed at the bottom of the evaporation tank 4. The heating component 7 is mainly composed of heating wires. The temperature inside the evaporation tank 4 can be increased through the heating wires, so as to evaporate the water in the L-phenylalanine mother liquor. The drain pipe 5 can be quickly cooled through the fan 6 and the pipeline. The water vapor moves upward, quickly liquefies when it encounters the drain pipe 5, and flows along the drain pipe 5 into the collection tank on one side, thus facilitating the collection of water. After the water is evaporated, the L-phenylalanine mother liquor is drained into the condensation tank 8 through a pipeline and a water pump, so that the L-phenylalanine mother liquor flows into the crystallization tank 10. A cooling component 9 is installed at the bottom of the condensation tank 8. The cooling component 9 is mainly composed of a water tank, pipelines, a water pump, and a heat dissipation mechanism, that is, a common water cooling mechanism. The L-phenylalanine mother liquor in the crystallization tank 10 can be quickly cooled through the cooling component 9. At this time, crystals will be produced in the L-phenylalanine mother liquor. This is the usage feature of the mother liquor recovery device for chemical preparation. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
