Abstract
Description
Technical Field
[0001] The utility model relates to the field of foam suppressors, in particular to a self-rotating defoamer. Background Art
[0002] During the chemical reaction process, the existence of foam will have the following adverse effects:
[0003] 1. Reduce production efficiency
[0004] The foam will occupy the space of the reaction vessel, reducing the volume of the material actually participating in the reaction, thus reducing the output per unit time. It may lead to instability of the reaction system, affect the control of the reaction process, and prolong the reaction time.
[0005] 2. Affect product quality
[0006] The foam may entrain impurities into the product, reducing the purity of the product. The uneven foam distribution may lead to inconsistent physical properties of the product, such as differences in density, hardness, etc.
[0007] 3. Increase safety risks
[0008] A large amount of foam may overflow from the reaction vessel, causing material loss and environmental pollution, and may even trigger dangerous situations such as fires or explosions. The foam will interfere with the accuracy of instruments such as liquid level measurement, affecting the monitoring of the reaction process.
[0009] Based on the negative impacts of the above-mentioned foam on the production process, product quality, efficiency, and environment, if we want to improve production efficiency, ensure product quality, reduce production costs, improve the working environment, and prevent secondary pollution, then we need to eliminate the foam.
[0010] The elimination of foam mainly adopts schemes such as using defoamers and mechanical defoaming paddles. Traditional mechanical defoaming paddles are of flat plate type, comb tooth type, etc. When the flat plate type defoaming paddle and the comb tooth type defoaming paddle rotate to defoam the foam, they scrape the foam through the plate surface or make non-breaking sliding motions with the comb teeth to refine the foam for defoaming. However, foam will pass through the gaps between the plate surface and the liquid level or between the comb teeth.
[0011] Therefore, traditional flat plate type or comb tooth type mechanical defoaming paddles have defects such as unsatisfactory defoaming effect, increased power consumption, and instability of the equipment. Therefore, it is necessary to improve the structure of the existing mechanical defoaming paddle. Summary of the Utility Model
[0012] The purpose of the utility model is to provide a self-rotating defoamer, which can strengthen the defoaming effect by self-rotation, reduce the defoaming power consumption, and make the equipment operate stably.
