Description

Technical Field

[0001] The utility model relates to the technical field of raw material processing, in particular to a chemical raw material stirring device. Background Art

[0002] When conducting chemical analysis experiments or producing chemical agents, it is necessary to mix and stir various chemical raw material solutions or raw material powders in order to achieve the best results. However, when some chemical solutions are stirred with raw material powders, some chemical raw material powders may interact with the solvent due to their special chemical properties, resulting in an increase in the viscosity of the solution.

[0003] In current chemical reaction operations, when we stir viscous chemical solutions, we face a significant challenge: due to the viscous nature of the solution, some edges and corners in the container are difficult to reach by the stirrer, making it difficult to effectively mix the solutions in these areas. In this case, the viscous chemical solution is very easy to adhere to and stick to the inner wall of the reaction container, forming residues that are difficult to remove. This adhesion phenomenon not only increases the difficulty of subsequent container cleaning, but more importantly, it directly leads to a significant increase in the time required for the stirring process, thereby reducing the overall efficiency of the stirring.

[0047] The working principle of the chemical raw material stirring device is described in detail below.

[0048] like Figure 1-5As shown, when the viscous solution in the sealed tank needs to be stirred, the first motor 6 and the second motor 12 are started through the control panel 9, and the first motor 6 will drive the second stirring component and the control component to work to stir the viscous solution in the sealed tank, and the second motor 12 will drive the first stirring component to work to stir the viscous solution, wherein the first stirring component and the second stirring component are used in combination to clean the viscous solution adhered to the edge inner wall 5, and then the control component is operated so that the chemical raw materials can be effectively mixed.

When the first motor 6 is started, the rotation of the first motor 6 will drive the rotating shaft 7 fixedly connected to its output end to rotate. The rotation of the rotating shaft 7 will drive the transmission shaft 16 rotatably connected to the support platform 1 to rotate through the mutually meshing bevel teeth 8. The rotation of the transmission shaft 16 will drive the first rotating gear 17 fixedly connected to it to rotate. The first rotating gear 17 will drive the second rotating gear 18 meshing with it to rotate. At this time, the first rotating gear 17 and the second rotating gear 18 rotate in opposite directions. At this time, the second rotating gear 18 transmits power to the auger 20 fixedly connected to it, and the viscous solution at the edge moves to the bottom through the auger 20. At the same time, the rotation of the transmission shaft 16 will drive the spiral blade 14 fixedly connected to it to rotate, thereby transporting the viscous solution at the bottom upward, thereby improving the stirring effect. When the transmission shaft 16 rotates, the third meshing gear 19 is driven to rotate through the meshing relationship between the first rotating gear 17 and the third rotating gear 19. The rotation of the third meshing gear drives the fixed rod 21 fixedly connected thereto to rotate. The rotation of the fixed rod 21 drives the scraper 22 to rotate and stir the viscous solution. The scraper 22 is arranged to contact the inner wall 5 so that the scraper 22 can clean the viscous solution adhering to the inner wall 5, thereby improving the mixing effect of the viscous solution. The mixing effect of the solution in the sealed tank can be improved by providing a rotating cleaning plate 24, and the surface of the viscous solution can be prevented from contacting the shell 4, thereby causing the mixing effect of the viscous solution to be poor. The weight of the scraper 22 itself can be reduced by providing a plurality of evenly arranged through holes 25 on the scraper 22, thereby reducing the load of the motor. At the same time, the through holes 25 can also increase the surface area of ​​the scraper 22 in contact with the solution, so that the viscous solution is easier to be stirred evenly. The transmission efficiency can be improved by setting the diameter of the first rotating gear 17 to be larger than the diameters of the second rotating gear 18 and the third rotating gear 19, thereby reducing the energy loss.
