Abstract
Description
Technical Field
[0001] This utility model relates to the field of fructose production technology, specifically to an evaporation device for producing crystalline fructose. Background Technology
[0002] In the evaporation process of fructose production, secondary steam recovery is a key step in reducing energy consumption. As a core component of steam purification, the filter plate needs to intercept viscous sugar mist and tiny crystals entrained in the steam to ensure the purity of the recovered steam. However, the special characteristics of fructose steam pose a significant challenge to cleaning the filter plate.
[0003] For example, the patent specification of an existing Chinese patent (publication number: CN217939152U) discloses an evaporation device for producing crystalline fructose, including a crystallizer, a condenser and a first connecting pipe. A second connecting pipe is fixedly connected to the crystallizer. A solenoid valve is provided on the outside of the first connecting pipe. A recovery tank is fixedly connected to one end of the second connecting pipe. The recovery tank is connected to one end of the solenoid valve. A liquid level sensor is provided on the inner wall of the recovery tank. A filter assembly is provided inside the recovery tank. A stirring assembly is provided inside the crystallizer.
[0004] However, during the implementation of the relevant technology, the following problems were found in the evaporation equipment for crystalline fructose production designed above: Although the device can filter the recovered steam by setting up a filter plate, the filter plate will become clogged during continuous use. If the device needs to clean the filter plate, it needs to be disassembled and cleaned, which requires shutting down the entire device. If the device is not shut down, unfiltered steam will be used directly, and some steam will overflow from the original location of the filter plate, which violates the original intention of energy saving. If the device is shut down, it will need to be reheated the next time it is used, which will still consume a lot of energy.
[0005] In view of this, an evaporation device for the production of crystalline fructose is provided to overcome the above-mentioned defects. Utility Model Content
[0006] The purpose of this invention is to provide an evaporation device for the production of crystalline fructose, so as to solve the problems mentioned in the background art.

A reflux pipe is fixedly connected to the top surface of the crystallizer, and a recovery box is connected to one side of the reflux pipe. Three square through slots are opened on the top surface of the recovery box. In the initial state, filter plates are placed inside the square through slots. A counterweight is fixedly connected to the top surface of the filter plates. A sealing plate is hinged to the side wall of the square slot. A movable slot is opened on the side wall of the square slot. A slidable movable block is set inside the movable slot. A connecting rod is set between the movable block and the sealing plate. The two ends of the connecting rod are respectively hinged to the bottom surface of the sealing plate and the side wall of the movable block. A contact spring is fixedly connected between the movable block and the movable slot.
[0008] Furthermore, a guide rod is fixedly installed inside the movable groove, and the movable block is slidably sleeved on the outer wall of the guide rod.
[0009] Furthermore, the guide rod and the abutment spring are arranged coaxially.

[0011] Furthermore, a scraper is fixedly connected to the bottom edge of the horizontal plate, and the scraper is inclined and closely attached to the inner wall of the crystallization tank.
[0012] Furthermore, the specific number of the horizontal plates and scrapers is four, and the four horizontal plates and four scrapers are all distributed in a circular array.
[0013] Furthermore, the specific number of sealing plates installed in a square groove is two, and both sealing plates are hinged to the side wall of the square groove and are arranged symmetrically.

[0021] 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.
[0022] Example 1
[0023] See Figure 1-4 An evaporation device for producing crystalline fructose includes a crystallizer 1, a condenser 7, and a drive motor 2. A reflux pipe 3 is fixedly connected to the top surface of the crystallizer 1. A recovery box 4 is connected to one side of the reflux pipe 3. Three square through slots are opened on the top surface of the recovery box 4. In the initial state, filter plates are placed inside the square through slots. A counterweight block 5 is fixedly connected to the top surface of the filter plates. A sealing plate 12 is hinged to the side wall of the square slot. A movable slot 15 is opened on the side wall of the square slot. A slidable movable block 14 is set inside the movable slot 15. A connecting rod 13 is set between the movable block 14 and the sealing plate 12. The two ends of the connecting rod 13 are respectively hinged to the bottom surface of the sealing plate 12 and the side wall of the movable block 14. A contact spring 17 is fixedly connected between the movable block 14 and the movable slot 15.
[0024] Furthermore, a guide rod 16 is fixedly installed inside the movable groove 15, and the movable block 14 is slidably sleeved on the outer wall of the guide rod 16. The guide rod 16 and the abutment spring 17 are coaxially arranged.
[0025] By setting a guide rod 16 and a movable block 14 that can be slidably sleeved on the outer wall of the guide rod 16, the movable block 14 is limited by the guide rod 16 during movement and cannot easily detach from the inside of the moving groove 15, so that the mechanism can operate stably. Furthermore, setting the guide rod 16 and the abutment spring 17 to be coaxial ensures that the guide rod 16 will not interfere with the abutment spring 17 when the movable block 14 compresses it, allowing the movement to proceed smoothly.
[0026] Furthermore, the bottom of the drive motor 2 is connected to a rotating shaft 8, a horizontal plate 9 is fixedly installed on the side wall of the rotating shaft 8, and three stirring rods 10 are fixedly installed at the bottom of the horizontal plate 9. The three stirring rods 10 are arranged in a linear array, and a scraper 11 is fixedly connected to the bottom edge of the horizontal plate 9. The scraper 11 is inclined and closely attached to the inner wall of the crystallization tank 1.
[0027] By setting up a horizontal plate 9 and a stirring rod 10, and setting three horizontal plates 9 in a linear array, the rotating shaft 8 can fully stir the syrup in the crystallization tank 1 while driving the horizontal plates 9 and the stirring rod 10 to rotate, so that the syrup can be heated more evenly.
[0028] By setting a scraper 11, and setting the scraper 11 to be inclined and closely attached to the inner wall of the crystallization tank 1, the scraper 11 can scrape off the syrup adhering to the inner wall of the crystallization tank 1 during rotation, and by taking advantage of its inclined characteristics, the scraped syrup can be pushed to the bottom for faster evaporation.
[0029] In addition, there are four horizontal plates 9 and four scraper bars 11, all arranged in a circular array.
[0030] It should be noted that there are two sealing plates 12 installed in a square groove. Both sealing plates 12 are hinged to the side wall of the square groove and are arranged symmetrically.
[0031] By setting two sealing plates 12 that are hinged to the side wall of the square groove and arranged symmetrically, the two sealing plates 12 can rotate to both sides when the counterweight 5 drives the filter plate to be inserted into the square groove, so that the filter plate can be placed inside the square groove.
[0032] In practice, traditional evaporation equipment typically uses filtration to crystallize and filter syrup during waste heat recovery to prevent the waste heat from affecting the syrup during reuse. However, the filters in conventional equipment are usually fixed and can become clogged after prolonged use. Therefore, the filter plates need to be disassembled and cleaned. However, conventional equipment is slow to disassemble the filters and requires the entire equipment to be shut down during disassembly to avoid wasting waste heat.
[0033] In this practical application, when a user needs to clean a certain filter plate, he can directly pull the counterweight 5 upward by pulling block 6, thereby bringing out the filter plate fixedly connected to the bottom of the counterweight 5. After the filter plate is brought out, the filter plates inside the other two square slots will continue to filter the hot steam to prevent it from contaminating the syrup, while the square slot where the filter plate has been removed will be blocked by two sealing plates 12.
[0034] When the filter is removed, the two sealing plates 12 lose contact. At this time, the elastic force of the contact spring 17 will push the moving block 14 to move along the moving groove 15. During the movement, the moving groove 15 will push the sealing plates 12 back to their original position through the connecting rod 13, so that the two sealing plates 12 return to the horizontal state, thereby blocking the top surface of the square groove and preventing hot steam from leaking out.
[0035] By setting up three square slots and three filter plates, and installing sealing plates 12 on both sides of the inner wall of the square slots, the device can quickly disassemble the filter plates without affecting the normal filtration function of the device. The hot steam generated inside the device will not leak out, which is in line with the purpose of energy saving.
[0036] Working principle: In the process of waste heat recovery, traditional evaporation equipment usually filters the syrup to crystallize it, so as to prevent the waste heat from affecting the syrup when it is reused. However, the filter in conventional equipment is usually fixed and will become clogged after long-term use. Therefore, the filter plate needs to be disassembled and cleaned. However, conventional equipment is not only slow to disassemble the filter, but also requires the entire equipment to be shut down during the disassembly process to avoid the waste of waste heat.
[0037] In this practical application, when a user needs to clean a certain filter plate, he can directly pull the counterweight 5 upward by pulling block 6, thereby bringing out the filter plate fixedly connected to the bottom of the counterweight 5. After the filter plate is brought out, the filter plates inside the other two square slots will continue to filter the hot steam to prevent it from contaminating the syrup, while the square slot where the filter plate has been removed will be blocked by two sealing plates 12.
[0038] When the filter is removed, the two sealing plates 12 lose contact. At this time, the elastic force of the contact spring 17 will push the moving block 14 to move along the moving groove 15. During the movement, the moving groove 15 will push the sealing plates 12 back to their original position through the connecting rod 13, so that the two sealing plates 12 return to the horizontal state, thereby blocking the top surface of the square groove and preventing hot steam from leaking out.
[0039] By setting up three square slots and three filter plates, and installing sealing plates 12 on both sides of the inner wall of the square slots, the device can quickly disassemble the filter plates without affecting the normal filtration function of the device. The hot steam generated inside the device will not leak out, which is in line with the purpose of energy saving.
[0040] 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.
