Description

Technical Field

[0001] This utility model relates to the field of chewing gum preparation technology, and in particular to a composite catalyst reaction device. Background Technology

[0002] Rosin glyceryl ester is an important raw material for making chewing gum. In chewing gum, rosin glyceryl ester is mainly used as the gum base (the basic agent of chewing gum).

[0003] Traditional methods for preparing rosin glycerol esters often use single inorganic acid catalysts, such as sulfuric acid and p-toluenesulfonic acid. While these catalysts possess certain catalytic activity, they suffer from numerous drawbacks. For example, they exhibit poor selectivity, easily triggering side reactions such as isomerization and oxidation of rosin molecules while promoting esterification, leading to a darker product color. Furthermore, inorganic acid catalysts are highly corrosive, requiring sophisticated equipment and increasing maintenance costs. Additionally, the production process generates large amounts of acidic wastewater, which is difficult to treat and causes severe environmental pollution. To address the shortcomings of traditional preparation techniques, composite catalyst technology has emerged and become a research hotspot. Composite catalysts achieve synergistic catalytic effects by rationally combining multiple catalytic components with different functions. For instance, advanced preparation techniques such as the sol-gel method and impregnation method are used, employing silica, alumina, etc., as supports to load acidic active components such as sulfonic acid groups and phosphate groups to prepare composite acid catalysts.

[0004] In the preparation of composite acid catalysts using the impregnation method, the impregnated support requires subsequent operations such as drying and calcination. Currently, in existing technologies, when the impregnated support is transferred to the drying equipment, the impregnating liquid carried from the impregnation tank is not effectively recovered. The impregnating liquid drips directly onto the ground upon exiting the impregnation tank, easily polluting the preparation environment. Therefore, this invention proposes a composite catalyst reaction device to solve the above problems. Utility Model Content

[0005] To address the aforementioned issues, this invention proposes a composite catalyst reaction device. After the carrier inside the carrier basket is impregnated in the impregnation tank, its position can be raised by a hydraulic cylinder. Then, the carrier basket is centrifuged by driving the platform to directly throw off the excess impregnation liquid on the carrier and recycle it back into the impregnation tank, thus avoiding impregnation liquid loss and pollution of the preparation environment.

[0006] To achieve the objectives of this utility model, the following technical solution is adopted:

[0007] A composite catalyst reaction device includes an impregnation tank, a carrier basket, and a recovery tank. The recovery tank is located above the impregnation tank, and the carrier basket is located inside the impregnation tank. A platform is rotatably mounted on the top of the recovery tank, and a hydraulic cylinder is mounted on the platform. The output end of the hydraulic cylinder is connected to the top of the carrier basket. An annular plate is mounted on the upper outer wall of the recovery tank, and a centrifugal drive motor is mounted on the annular plate. A drive gear is installed at the output end of the centrifugal drive motor. A geared ring is installed on the outer wall of the platform, and the geared ring meshes with the drive gear.

[0008] The impregnation tank is symmetrically equipped with lifting cylinders, and the lower outer wall of the recovery tank is equipped with a support ring. The output end of the lifting cylinder is connected to the bottom of the support ring.

[0009] A further improvement is that: the outer wall of the carrier basket has a filter hole structure, the upper opening of the carrier basket is provided with a cross bracket, the upper opening of the carrier basket is divided into four notches by the cross bracket, and the output end of the hydraulic cylinder is connected to the cross bracket.

[0010] A further improvement is that an observation window is provided on the lower outer wall of the recycling tank above the support ring.

[0011] A further improvement is that: the upper end of the recycling tank is provided with a cover, the center of the cover is provided with a through hole, the upper end of the hydraulic cylinder extends from the through hole to the top of the cover, and the bottom of the cover is connected to the top of the ring plate.

[0012] A further improvement is that a discharge pipe is provided on the lower outer wall of the impregnation tank, and a butterfly valve is provided on the discharge pipe.

[0013] A further improvement is that: a sealing block is provided at the bottom of the platform, and the number and shape of the sealing block are adapted to the gap. After the hydraulic cylinder retracts and moves the carrier basket upward into the recycling tank, the sealing block seals the gap.

[0014] The beneficial effects of this utility model are as follows: This utility model sets up a recovery tank above the impregnation tank and a hydraulic cylinder on a rotating platform at the top of the recovery tank. By connecting the output end of the hydraulic cylinder to a carrier basket located inside the impregnation tank, the carrier inside the carrier basket can be raised to a higher position by the hydraulic cylinder after impregnation in the impregnation tank. Then, by driving the platform to rotate, the carrier basket is centrifuged, so that the excess impregnation liquid on the carrier can be directly thrown out and recovered into the impregnation tank, avoiding the loss of impregnation liquid and pollution of the preparation environment.

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1-3 As shown, this embodiment proposes a composite catalyst reaction device, including an impregnation tank 1, a carrier basket 2, and a recovery tank 3. The recovery tank 3 is located above the impregnation tank 1, and the carrier basket 2 is located inside the impregnation tank 1. A platform 4 is rotatably mounted on the top of the recovery tank 3, and a hydraulic cylinder 5 is mounted on the platform 4. The output end of the hydraulic cylinder 5 is connected to the top of the carrier basket 2. An annular plate 6 is provided on the upper outer wall of the recovery tank 3, and a centrifugal drive motor 7 is mounted on the annular plate 6. A drive gear 8 is installed on the output end of the centrifugal drive motor 7. A gear ring 9 is installed on the outer wall of the platform 4, and the gear ring 9 meshes with the drive gear 8. Lifting cylinders 10 are symmetrically arranged on the impregnation tank 1, and a support ring 11 is provided on the lower outer wall of the recovery tank 3. The bottom of the support ring 11 is connected to the output end of the lifting cylinder 10.

[0021] When the composite catalyst reaction device of this invention impregnates the carrier, the carrier is placed in the carrier basket 2, and the top of the carrier basket 2 is connected to the hydraulic cylinder 5 (in this invention, the carrier basket 2 can be connected to the output end of the hydraulic cylinder 5 via a quick connector; the output is not detailed here but can be set as needed). After the carrier impregnation is completed, the carrier basket 2 is raised as a whole by controlling the retraction of the hydraulic cylinder 5, so that the carrier basket 2 is separated from the impregnation liquid inside the impregnation tank 1. Then, the centrifugal drive motor 7 is started, which drives the drive gear 8 to drive the platform 4 with the toothed ring 9 to rotate on the top of the recovery tank 3, thereby driving the carrier basket 2 to rotate, so as to throw the impregnation liquid on the surface of the carrier and the surface of the carrier basket 2 into the impregnation tank for recovery. By controlling the lifting cylinder 10 to lift, the recovery tank 3 can be raised as a whole, making it easier to remove the carrier from the gap formed between the recovery tank 3 and the impregnation tank 1 (the carrier basket 2 of this invention can be a carrier basket 2 with a discharge port at the bottom, and the impregnated carrier can be removed by opening the discharge port).

[0022] The outer wall of the carrier basket 2 has a filter hole structure. A cross-shaped support 12 is provided inside the upper opening of the carrier basket 2, dividing the upper opening into four notches. The output end of the hydraulic cylinder 5 is connected to the cross-shaped support 12. A sealing block 17 is provided at the bottom of the platform 4. The number and shape of the sealing blocks 17 are adapted to the notches. After the hydraulic cylinder 5 retracts, it moves the carrier basket 2 upwards into the recovery tank 3, and then the sealing blocks 17 seal the notches. By setting the sealing blocks 17 to cooperate with the notches, the circumferential stability during centrifugation can be improved, and the carrier can be prevented from being thrown out by centrifugation.

[0023] An observation window 13 is provided on the lower outer wall of the recovery tank 3 above the support ring 11. The observation window 13 facilitates the observation of the impregnation process.

[0024] The upper end of the recycling tank 3 is provided with a cover 14, and the center of the cover 14 is provided with a through hole. The upper end of the hydraulic cylinder 5 extends from the through hole to the top of the cover 14, and the bottom of the cover 14 is connected to the top of the ring plate 6. The cover 14 is provided to prevent the slip ring 9 and the drive gear 8 from slipping.

[0025] The lower outer wall of the impregnation tank 1 is provided with a discharge pipe 15, and a butterfly valve 16 is provided on the discharge pipe 15. The discharge pipe 15 is used to discharge the impregnation liquid for centralized recycling.

[0026] This invention features a recovery tank 3 above an impregnation tank 1, and a hydraulic cylinder 5 mounted on a rotating platform 4 at the top of the recovery tank 3. The output end of the hydraulic cylinder 5 is connected to a carrier basket 2 located inside the impregnation tank 1. After the carrier inside the carrier basket 2 has been impregnated in the impregnation tank 1, its position can be raised by the hydraulic cylinder 5. Then, the platform 4 is driven to rotate to control the carrier basket 2 to centrifuge, thereby directly throwing out excess impregnation liquid from the carrier and recovering it back into the impregnation tank 1, thus avoiding loss of impregnation liquid and pollution of the preparation environment.
