Description

Technical Field

[0001] This utility model relates to the field of cooling water circulation, and in particular to a cooling water circulation device for starch production. Background Technology

[0002] Starch is a natural polysaccharide macromolecule that is widely distributed in nature. In the starch production process, it is necessary to cool the relevant equipment or materials, which is usually done using cooling water circulation equipment.

[0003] A search revealed a Chinese patent publication number: CN220276945U, which discloses a cooling water circulation device. This device includes a reaction tank and a cooling cylinder embedded and fixed at the top of the reaction tank. A water storage tank is provided on one side of the reaction tank. A top cover is embedded and fixed at the top of the water storage tank, and a water pump is installed through the top cover. Positioning grooves are provided at both ends of the water storage tank. Protrusions are fixed on both sides of the inner wall of the top cover, and filter elements are embedded and fixed through the protrusions. Telescopic grooves are provided at both ends of the top cover. Springs are embedded in both telescopic grooves, and positioning blocks that engage with the positioning grooves are elastically inserted through the springs. This utility model features a top cover embedded in the top of a water storage tank, with a filter element fixed inside the top cover. As the water pump circulates cooling water, the filter element filters the water heated by the reaction tank, causing impurities to be released. Simultaneously, when cleaning the filter element, a positioning block is pressed against the side wall of the water storage tank, causing it to move out of the positioning groove. This allows the top cover to be removed from the water storage tank, and the filter element can be pried out between the two protrusions for cleaning. After cleaning, the filter element is fixed, and the top cover is inserted into the water storage tank. A spring in the telescopic groove pushes the positioning block to fit into the positioning groove, thus keeping the top cover fixed. This facilitates the disassembly, cleaning, and installation of the filter element, significantly reducing the risk of pipe blockage due to impurities.

[0004] In the above-mentioned technologies, although the disassembly, cleaning and installation of the filter element greatly reduces the possibility of pipe blockage due to impurities, the cooling water filtered by the filter element only enters the water storage tank through one through hole, which easily causes poor cooling water flow. In addition, the filter element is not easily fixed by the spring-driven positioning block. Therefore, a cooling water circulation device for starch production is proposed to solve the above problems. Utility Model Content

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.

[0019] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a starch production cooling water circulation device, including a reaction tank 1. A cooling cylinder 2 is clamped to the upper inner wall of the reaction tank 1. The cooling cylinder 2 is used to cool and exchange heat for the materials in the reaction tank 1. A water inlet pipe 4 is fixedly connected to the right inner wall of the cooling cylinder 2. The water inlet pipe 4 is used to transport cooling water from a water tank 9 to the cooling cylinder 2. The water inlet pipe 4 is fixedly connected to a cover plate 8 through a water pump 5. The water pump 5 provides power for the cooling water circulation. The upper inner wall of the cover plate 8 is slidably connected to the outer wall of a rotating rod 15. The rotation of the rotating rod 15 drives the fixed block 16 to move synchronously. When the rotating rod 15 drives the fixed block 16 to rotate above the limiting groove 17, the cover plate 8 can be moved to achieve the desired effect. The opening and closing control of the water tank 9 is achieved by having two symmetrical sleeves on the lower side of the cover plate 8. The lower sleeves of the cover plate 8 can be snapped onto the outer wall of the fixed column 22. A limit groove 17 is provided on the inner wall of the cover plate 8. The limit groove 17 cooperates with the fixing block 16 of the rotating rod 15 to restrict the movement of the cover plate 8. A water outlet pipe 11 is fixedly connected to the right side of the cooling cylinder 2. The water outlet pipe 11 is used to discharge the water that has completed heat exchange in the cooling cylinder 2 to the condenser 10, and then enter the cooling cylinder 2 to achieve circulation. The water outlet pipe 11 is fixedly connected to the water tank 9 through the condenser 10. The condenser 10 cools the heated cooling water. A top cover 19 is snapped onto the upper side of the water tank 9. The top cover 19 seals the water tank 9 and installs a filter element 18 to filter impurities.

[0020] Reference Figures 5-7The top cover 19 has multiple through holes on its lower side for cooling water to pass through, working with the filter element 18 to filter impurities. The upper side of the top cover 19 is equipped with a limiting arc-shaped block to help position the filter element 18. The filter element 18 is detachably installed on the upper inner wall of the top cover 19. The filter element 18 is removable and can be replaced regularly to ensure water quality. A fixing post 22 is fixedly connected to the upper side of the top cover 19, providing a snap-fit ​​support for the sleeve of the cover plate 8. A sliding post 20 is elastically connected to the upper inner wall of the fixing post 22 via a spring 21. The spring 21 provides elastic extension and retraction to assist the cover plate 8 in snapping / unscrewing. The lower outer wall of the sliding post 20 is slidably connected to the upper inner wall of the fixing post 22. One end of the spring 21 is fixedly connected to the inner wall of the fixing post 22, and the other end is fixedly connected to the outer wall of the sliding post 20. A vertical plate 7 is fixedly connected to the upper side of the box 9. The vertical plate 7 provides installation support for the bearing plate 6 and the rotating rod 15. The bearing plate 6 is fixedly connected to the outer wall of the vertical plate 7. The bearing plate 6 is used to support and fix the water pump 5 and provide an installation platform. A through groove is opened on the inner wall of the bearing plate 6. The through groove provides space for the water inlet pipe 4 to pass through, which facilitates the connection between the water inlet pipe 4 and the cover plate 8. The upper side of the bearing plate 6 is used to fix the water pump 5 and provides an installation and fixing position for the water pump 5. A rotating rod 15 is rotatably connected to the inner wall of the vertical plate 7. The rotating rod 15 rotates on the inner wall of the vertical plate 7, driving the fixing block 16 to rotate synchronously. A fixing block 16 is fixedly connected to the outer wall of the rotating rod 15. The upper or lower side of the fixing block 16 acts on the cover plate 8 to limit the position of the cover plate 8. A stirring assembly is provided on the upper side of the cooling cylinder 2. The stirring assembly is used to stir the cooling water in the cooling cylinder 2.

[0021] Reference Figures 2-4 The stirring assembly includes a motor 3, which provides power to the stirring assembly and drives the stirring rod 12 to rotate. The stirring rod 12 is rotatably connected to the upper inner wall of the cooling cylinder 2. The stirring rod 12 is fixed to the output shaft of the motor 3 to ensure power transmission. The upper inner wall of the stirring rod 12 is fixedly connected to the output shaft of the motor 3. The lower side of the stirring rod 12 is fixedly connected to the stirring blade 13. The stirring blade 13 rotates with the stirring rod 12 to stir the cooling water in the cooling cylinder 2. There are two stirring blades 13, which are symmetrically arranged. The symmetrical stirring blades 13 make the cooling water more evenly stirred and improve the heat exchange effect. The rear side of the stirring blade 13 is sharp. The sharp design reduces stirring resistance and enhances water flow turbulence. A fixing strip 14 is fixedly connected to the inner wall of the cooling cylinder 2. The fixing strip 14 plays a role in turbulence and turbulence of the cooling water during the stirring process.

[0022] Working principle: When the device is started, the water pump 5 acts as the power source, delivering the cooling water in the water tank 9 to the cooling cylinder 2 through the water inlet pipe 4. The cooling cylinder 2 is attached to the upper inner wall of the reaction chamber 1, forming a heat exchange contact with the starch production materials in the reaction chamber 1, and achieving cooling by absorbing the heat of the materials through the cooling water.

[0023] Simultaneously, the stirring assembly on the upper side of the cooling cylinder 2 begins to operate: the motor 3 drives the stirring rod 12 to rotate, causing the symmetrically arranged stirring blades 13 on its lower side to rotate synchronously. The sharp design on the rear side of the stirring blades 13 reduces stirring resistance and enhances cooling water turbulence; the fixing strips 14 on the inner wall of the cooling cylinder 2 further assist in turbulence, making the cooling water flow more evenly in the cooling cylinder 2 and improving the heat exchange efficiency with the materials in the reaction tank 1.

[0024] After heat exchange is completed, the heated cooling water is discharged through the outlet pipe 11 on the right side of the cooling cylinder 2 and enters the condenser 10 for cooling. The cooled water flows into the water tank 9 through the through hole on the lower side of the top cover 19. When it flows through the removable filter element 18 on the upper inner wall of the top cover 19, impurities are filtered out, ensuring the cleanliness of the circulating water.

[0025] The opening and closing of the water tank 9 is achieved through the cooperation of the rotating rod 15 and the cover plate 8: when the rotating rod 15 on the vertical plate 7 is rotated, the fixing block 16 on its outer wall rotates with the rotating rod 15. When the fixing block 16 moves above the limiting groove 17 of the cover plate 8, it can push the cover plate 8 to slide. When the sleeve on the lower side of the cover plate 8 is engaged with the fixing post 22 on the top cover 19, the sliding post 20 supported by the spring 21 inside the fixing post 22 elastically extends and retracts, assisting the cover plate 8 to be stably engaged, thereby closing the water tank 9. The reverse operation can open the cover plate 8, which is convenient for maintenance operations such as replacing the filter element 18.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
