Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of magnesium stearate production, in particular to a catalytic adding device for magnesium stearate production. Background Art
[0002] Magnesium stearate is a widely used additive and PVC stabilizer. It plays a great role as an additive and is used in many industries and fields. At present, the production process of magnesium stearate in China is diversified, mainly by double decomposition method and direct synthesis method. The magnesium stearate produced by the direct synthesis process has high yield, high purity, good color, good transparency, low free acid and magnesium content, stable quality, and no wastewater discharge in the production process. However, the direct method produces magnesium stearate. The catalyst is added too fast and the reaction temperature rises sharply, which is particularly prone to the overflow of the flying pot and causes the danger of scalding to the workers. The catalyst is added too slowly and the reaction is not good, which causes the free acid to be high. It is impossible to complete the phase change process of the slurry to the powder or the phase change process causes the current to increase and the material cannot be driven and the machine is stuck, which seriously damages the production equipment. Therefore, a suitable magnesium stearate production catalytic adding device is needed to improve the production effect of magnesium stearate.
[0003] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. The amount of catalyst added for producing magnesium stearate cannot be effectively controlled. Adding it too quickly will cause the reaction temperature to rise, resulting in the risk of overflowing the pot and scalding the workers. If the catalyst is added too slowly, the phase change process from slurry to powder cannot be completed, resulting in machine jams and serious damage to the production equipment; 2. There are often certain impurities in the catalyst, which will affect the accuracy of magnesium stearate production. At the same time, the catalyst cannot be effectively and evenly sprayed in the reactor, which will also have a certain impact on the production accuracy of magnesium stearate. Utility Model Content

To achieve the above purpose, the utility model provides the following technical solution: a catalytic addition device for magnesium stearate production, comprising a feeding mechanism, a spraying mechanism is installed at the bottom of the feeding mechanism, and the feeding mechanism runs through the top of the reaction mechanism.
[0005] The feeding mechanism comprises a catalyst feeding pipe, a catalyst control valve is installed inside the catalyst feeding pipe, a catalyst filter is inserted inside the catalyst feeding pipe, and a sealing ring is glued to the outside of the catalyst filter.
