Description

Technical Field

[0001] The utility model belongs to the technical field of crystallization tanks, in particular to a stirring evaporation crystallization tank for chemical industry. Background Art

[0002] Crystallization is the process of solute precipitation in the form of crystals after a solution exceeding saturation concentration is cooled. Crystallization is an important process for preparing refined products in the pharmaceutical, food and chemical industries. When the solution is in an unstable zone, it will crystallize immediately. It may crystallize too quickly, forming a large number of small crystals that may contain certain impurities. Usually, larger and more orderly crystals are obtained by controlling the cooling rate or evaporation rate. The formation of crystal nuclei requires a certain amount of energy, which is usually provided by stirring. Stirring evaporation crystallization tanks are commonly used in crystallization processes. However, existing chemical stirring evaporation directly discharges steam, resulting in energy loss. Utility Model Content

[0021] In this embodiment, the base 1 serves as the supporting structure of the entire crystallization tank, ensuring that the tank body 2 is firmly placed and providing an installation foundation for other components. The tank body 2 is directly used to store chemical raw materials to be processed and is the main place for crystallization reaction. The exhaust pipe 3 not only facilitates steam discharge, but also improves the initial cooling effect of steam during the discharge process by increasing the contact area. In addition, the exhaust pipe 3 extends into the cooling box 4, further promoting the condensation of steam and effectively reducing energy loss. The cooling box 4 efficiently condenses the steam discharged from the exhaust pipe 3. This design not only recovers the heat energy in the steam and prevents burns, but also because the exhaust pipe 3 is long and wrapped around the outside of the tank body 2, the waste heat also insulates the tank body 2. The drain pipe 8 is used to discharge condensed water. By setting a waterproof valve, the discharge timing and flow rate of the condensed water can be conveniently controlled, avoiding the adverse effects of condensed water on chemical raw materials or equipment. The stirring assembly provides external force through stirring to promote the formation of crystal nuclei and the uniform growth of crystals. The stirring action also helps to improve the mass transfer and heat transfer efficiency in the solution, thereby optimizing the crystallization process and obtaining larger and more neat crystals.

[0022] In a further preferred embodiment of the present invention, the stirring assembly includes a mounting frame 14, a stirring rod 15, a limiting cylinder 16, a limiting block 17, a cover plate 18 and a motor 19, the mounting frame 14 is fixed in the tank body 2, the stirring rod 15 is rotatably mounted on the mounting frame 14, the limiting cylinder 16 is fixed on the top of the stirring rod 15, the limiting block 17 is movably mounted in the limiting cylinder 16, the cover plate 18 is detachably mounted on the top of the tank body 2, the cover plate 18 is used to close the tank body 2, the limiting block 17 is rotatably connected to the cover plate 18, the motor 19 is mounted on the top of the cover plate 18, and the output shaft of the motor 19 is fixedly connected to the limiting block 17.

The cover 18 is used to close the tank body 2 and support components such as the motor 19. The detachable design of the cover 18 facilitates maintenance and cleaning of the equipment. The optimized design of the stirring assembly improves the performance of the entire stirring evaporation crystallization tank. The improved stirring effect helps to optimize the crystallization process parameters and improve product quality and output. At the same time, the stability and reliability of the equipment are also enhanced.

[0024] In a further preferred embodiment of the present invention, a discharge port is provided at the bottom of the tank body 2, and a collection tank 10 for collecting crystals is installed on the internal thread of the discharge port. Two handles 11 and a support ring 12 are installed on the collection tank 10, and a sealing ring 13 that can contact the bottom of the tank body 2 is installed on the top of the support ring 12.

A plurality of fixing bolts that can be threadedly connected to the limiting ring are threadedly installed on the tank body 2, and two lifting rings 20 are provided on the top of the cover plate 18.

[0031] In this embodiment, the limiting ring is in close contact with the inner wall of the tank body 2, and mainly plays the role of positioning and sealing, ensuring that the cover 18 can be accurately aligned with the opening of the tank body 2 when closed, and preventing chemical raw materials or steam from leaking. Through contact with the inner wall of the tank body 2, the limiting ring can also provide a certain supporting force to enhance the stability of the cover 18. By rotating the fixing bolt, it can be tightly connected to the limiting ring, so that the cover 18 is firmly fixed to the tank body 2. This threaded connection method is not only simple and reliable, but also easy to disassemble and install, which is beneficial to the maintenance and cleaning of the equipment. The lifting ring 20 is used to lift and carry the cover 18, so that the operator can use lifting equipment to easily remove or install the cover 18 from the tank body 2, which helps to reduce the risk and labor intensity of manual operation and improve work efficiency.

The observation window is used to observe the crystallization state, and the light shield is used to block the interference of external light on the crystallization state in the observation window.

[0034] To sum up, compared with the relevant technology, the present device discharges the steam generated by heating and concentration by setting an exhaust pipe 3, and feeds back the steam energy to the surface of the tank body 2, reducing the energy required for heating, while improving the energy utilization rate and reducing waste. The steam is condensed by setting a cooling box 4 to prevent burns. The tank body 2 can be kept in a relatively sealed state by combining the collection tank 10 with the cover 18.
