Description

Technical Field

[0001] The utility model belongs to the technical field of chemical production, and in particular relates to an evaporator for chemical production. Background Art

[0002] The evaporator in chemical production is a device used to convert liquid into gas. It plays an important role in chemical production. It uses evaporation to heat the solution, vaporize and remove part of the solvent, thereby increasing the concentration of the solution, that is, the solution is concentrated. The evaporator is mainly composed of a heating chamber and an evaporation chamber. The heating chamber provides the liquid with the heat required for evaporation, causing the liquid to boil and vaporize; the evaporation chamber completely separates the gas and liquid phases.

[0003] For example, the Chinese patent with the publication number CN220736195U discloses an evaporator for chemical production, including an evaporator body, a motor 1 is arranged on the top of the evaporator body, a transmission shaft 1 is fixedly connected to the output end of the motor 1, a disc is fixedly connected to the bottom of the transmission shaft 1, a rotating shaft is rotatably connected inside the disc, and a stirring blade is fixedly connected to the outer wall of the rotating shaft. In the utility model, the effect of fully stirring the liquid inside the evaporator is achieved through the coordination between the transmission shaft 1, the sleeve, the transmission gear 1, the transmission gear 2, the disc, the rotating shaft, and the stirring blade, which solves the problem that there may be no stirring device, and the heating cannot be uniformly applied during the process of evaporating chemical products using the heater, resulting in incomplete heating, resulting in the chemical products cannot be completely concentrated, and the product is unqualified, thereby improving the qualified rate of using the evaporator to evaporate chemical raw materials.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: although the above evaporator improves the qualified rate of chemical raw materials evaporated by the evaporator, its feed inlet does not have a filtering mechanism. When the chemical raw materials enter the evaporator through the feed inlet, some solid particle impurities may remain inside the chemical raw materials, which may reduce the quality of the product and be unfavorable to production. In view of this, we propose a chemical production evaporator. Utility Model Content
