Description

Technical Field

[0001] This utility model relates to the field of chemical reagent production, specifically a crystallization device for chemical reagent production. Background Technology

[0002] Chemical reagents are a class of highly pure chemical substances prepared or produced for chemical experiments, chemical analysis, chemical research, and other purposes. They are commonly used substances in chemical experiments and have wide applications in many fields such as chemistry, chemical engineering, biology, medicine, and materials science. In the production of chemical reagents, the crystallization process is crucial, as it directly affects key indicators such as the purity, yield, and crystal morphology of the product.

[0003] However, existing crystallization equipment often has some shortcomings. For example, the internal stirring device of traditional equipment is not designed reasonably, which leads to uneven mixing of the solution, resulting in inconsistent crystallization rates and inconsistent crystal quality. In addition, some crystals tend to remain and stick to the inner wall after crystallization. Therefore, a crystallization equipment for chemical reagent production is proposed to solve the above problems. Utility Model Content

[0026] 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.

[0027] In the embodiments, by Figure 1-4 The present invention discloses a crystallization device for producing chemical reagents. The device includes a support frame 1, a reaction vessel 2 fixedly connected inside the support frame 1, a feed inlet 3 on the side of the reaction vessel 2, a discharge outlet 4 at the bottom of the reaction vessel 2, a fixing frame 5 fixedly connected to the top of the reaction vessel 2, a connecting frame 6 fixedly connected inside the reaction vessel 2, three rotating shafts 7 rotatably connected inside the reaction vessel 2 and each rotatably connected to the connecting frame 6, a plurality of stirring rods 8 fixedly connected to the outer side of each of the three rotating shafts 7, a scraper 9 slidably connected to the connecting frame 6 fixedly connected to the outer side of the middle rotating shaft 7, and a rotating device 10 fixedly connected to each of the three rotating shafts 7 inside the fixing frame 5.

[0028] Among them, the feed inlet 3 is inclined inward and is wider at the top and narrower at the bottom.

[0029] In this embodiment, during actual use, the feed inlet 3 provides a location for adding chemical reagents. The feed inlet 3, which is wider at the top and narrower at the bottom, makes it more convenient to add reagents, and the reagents will slide down the slope to prevent the reagents from accumulating.

[0030] The rotating device 10 includes a motor 101 fixedly connected to the top of the fixed frame 5. The outer side of the output shaft of the motor 101 is fixedly connected to the middle rotating shaft 7. A first gear 102 is fixedly connected to the outer side of the output shaft of the motor 101. Connecting shafts 103 fixedly connected to the fixed frame 5 are fixedly connected to the outer sides of the left and right rotating shafts 7. A second gear 104 meshing with the first gear 102 is fixedly connected to the outer side of each of the two connecting shafts 103.

[0031] In this embodiment, during actual use, the start of the motor 101 will drive the central rotating shaft 7 to rotate, and at the same time drive the first gear 102 to rotate. When the first gear 102 meshes with the two second gears 104, the rotating shafts 7 on the left and right sides will also rotate, thereby causing the stirring rods 8 on the outside of the three rotating shafts 7 to rotate, so as to stir the inside of the reaction vessel 2.

[0032] The top surface of the connecting frame 6 is inclined inward, and the top surface of the connecting frame 6 is narrower at the top and wider at the bottom.

[0033] In this embodiment, during actual use, the connecting frame 6 is a support structure for the rotating shaft 7, and its inclined setting makes its upper part narrower, so that the reagent can slide down the inclined surface without accumulating on the connecting frame 6.

[0034] The connecting frame 6 has a groove inside, and the top of the scraping frame 9 is fixedly connected to a slider 11 that is slidably connected to the groove.

[0035] In this embodiment, during actual use, the rotation of the intermediate rotating shaft 7 can drive the scraper 9 to rotate, so that the scraper 9 scrapes the lower end of the inner wall of the reactor and also has a stirring function. When the scraper 9 rotates, the slider 11 above it will also slide inside the chute, and the chute further restricts the rotation direction of the scraper 9.

[0036] The bottom of the reactor 2 is arc-shaped, the discharge port 4 is located in the middle of the reactor 2, and the scraper 9 is W-shaped.

[0037] In this embodiment, during actual use, the arc-shaped bottom of the reactor 2 facilitates the downward flow of reagents. The discharge port 4 is located at the lowest point of the reactor 2, and a switch valve is installed inside the discharge port 4. At the same time, the W-shaped scraper 9 can scrape the bottom wall of the reactor 2 to prevent the crystals from sticking together.

[0038] Working principle:

[0039] When producing crystallization of chemical reagents, the chemical reagents can first be put into the reaction vessel 2 through the feed port 3. By starting the motor 101, multiple stirring rods 8 and scraper 9 can stir and agitate the inside of the reaction vessel 2. The multiple stirring rods 8 are interlaced. The inside of the reaction vessel 2 can be equipped with heating equipment to accelerate the crystallization of the reagents. After crystallization is completed, it can be discharged through the discharge port 4 below. Subsequently, water can be added and the motor 101 can be started to clean the inside of the reaction vessel 2.
