Description

Technical Field

[0001] This utility model relates to the field of chemical product processing technology, specifically to a stirring tank for chemical product production. Background Technology

[0002] In a broad sense, a stirred tank is a container that involves physical or chemical reactions. Through structural design and parameter configuration, it operates on the same principle as a reaction vessel, achieving the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. A stirred tank is essentially a stainless steel container that involves physical or chemical reactions, with its structural design and parameters tailored to specific process requirements. The configuration, design conditions, processes, inspection, manufacturing, and acceptance of stirred tanks must adhere to relevant technical standards to ensure the achievement of the required heating, evaporation, cooling, and low-to-high-speed mixing reaction functions.

[0003] In the existing raw material catalyst production process, liquid, triethanolamine, and diethylisopropanolamine are added to a stirred tank, followed by the addition of raw materials such as urea. When the temperature is reached, catalyst powder needs to be added to the stirred tank. Typically, the operator first opens the feed inlet of the stirred tank, and after feeding is complete, the stirring mechanism inside the stirred tank is activated to mix the powder with the liquid.

[0004] This operating method has certain drawbacks. During the catalyst powder feeding process, the stirring mechanism needs to be stopped to avoid dust flying up when powder is added directly while the stirring paddle is rotating. However, this intermittent operation not only reduces production efficiency, but also, because the stirring stops during feeding, the powder tends to accumulate in a certain area, making it difficult to achieve uniform mixing, thus affecting the quality of the final product. Utility Model Content

[0005] In view of this, the present invention provides a stirring vessel for chemical product production. The present invention allows catalyst powder to be added and stirred at the same time, which accelerates the dissolution rate of catalyst powder and liquid, thereby improving the stirring speed.

[0006] To solve the above-mentioned technical problems, this utility model provides a mixing tank for chemical product production, including a mixing drum. A mixing assembly is installed inside the mixing drum, and the mixing assembly includes a feed cylinder located at the top of the mixing drum. The outer arc surface of the feed cylinder has several material distribution holes. A mixing rod is installed at the bottom of the mixing drum, penetrating through the bottom of the feed cylinder. A spiral conveying blade is installed at the top of the mixing rod. The operator pours catalyst powder into the top feed cylinder, and then the mixing rod rotates inside the mixing drum, indirectly causing the spiral conveying blade to rotate in contact with the feed cylinder. This causes the catalyst powder to fall from the bottom of the feed cylinder into the mixing drum and come into contact with the liquid, thus increasing the mixing speed by simultaneously adding and mixing the catalyst powder.

[0007] The stirring assembly also includes a dispersion disc mounted on the stirring rod, located at the bottom of the feed cylinder. The dispersion disc is fixedly mounted on the stirring rod by welding, so that the rotation of the stirring rod can indirectly drive the rotation of the dispersion disc, thereby indirectly bringing the catalyst powder at the bottom of the feed cylinder into contact with the upper surface of the dispersion disc, thus achieving the effect of dispersing the catalyst powder.

[0008] The stirring assembly also includes several stirring blades mounted on a stirring rod, with the stirring blades located at the bottom of the dispersion disc; that is, the stirring blades rotate, thereby accelerating the dissolution rate of the catalyst powder in the liquid.

[0009] The stirring assembly also includes a cleaning scraper mounted on the stirring rod, which is slidably fitted against the inner wall of the stirring drum; that is, the rotation of the stirring rod can drive the cleaning scraper to rotate, thereby scraping off the catalyst powder adhering to the inner wall of the stirring drum.

[0010] The stirring assembly also includes a motor located at the bottom of the stirring drum, with the motor's output shaft connected to one end of the stirring rod; that is, the motor provides drive for the stirring rod, thereby causing the stirring rod to rotate.

[0011] The top of the feed cylinder is equipped with a threaded cap; that is, the feed cylinder is rotated through the threaded cap to facilitate the closing or opening of the feed cylinder.

[0012] The top of the mixing drum is equipped with a liquid injection pipe, and the bottom of the mixing drum is equipped with a discharge port; that is, the liquid injection pipe facilitates the addition of liquid, and the discharge port is used to discharge the liquid in the mixing drum.

[0013] The outer arc surface of the mixing drum is provided with a support block, and the bottom of the support block is provided with a support column; thus, it provides support for the mixing drum.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. By setting up a feed cylinder, stirring blades, dispersing holes, spiral conveying blades, and stirring rods, the catalyst powder in the feed cylinder is conveyed to the stirring cylinder by the spiral conveying blades. Then, by rotating the stirring blades, the dissolution rate of the catalyst powder and the liquid can be accelerated.

[0015] 2. The cleaning scraper can remove the powder that floats to the inner wall of the mixing drum, thereby reducing the loss caused by catalyst powder adhering to the inner wall of the mixing drum. Attached Figure Description
