Description

TECHNICAL FIELD

[0001] The utility model relates to scraper evaporator technical field, concretely relates to a discharge mechanism of horizontal scraper evaporator. BACKGROUND

[0002] The working principle of the scraper evaporator is based on the film evaporation of the material on the heating surface. By controlling the heating temperature and the scraper speed, efficient evaporation at low temperature is realized, the loss of heat-sensitive components of the material is reduced, and the evaporation efficiency and product quality are improved. The existing scraper evaporator often uses a vacuum pump to reduce the boiling point of the solution to be evaporated, so the evaporation cylinder needs to maintain a certain degree of sealing during operation.

[0003] For example, the Chinese patent application with the application publication number CN111617503A discloses a scraper type low-temperature evaporator, which includes an evaporator body and a vacuum pumping device. The evaporator body includes an evaporator cylinder. The evaporator cylinder includes an upper cylinder and a lower cylinder that are interconnected. The upper cylinder is internally provided with a condensing device and a condensate water collecting structure. The outer wall of the upper cylinder is provided with a condensate outlet, which is in communication with the condensate water collecting structure. The condensate outlet is connected to the vacuum pumping device. The lower cylinder is externally provided with a jacket. The bottom of the lower cylinder is provided with an inlet and an outlet. The evaporator can improve the concentration of the material and reduce production costs.

[0004] However, the above-mentioned device still has some defects: the discharge outlet of the above-mentioned device is closed or opened by a valve. When the solution in the evaporator is completely evaporated, the discharge outlet is used to discharge solid powder. At this time, the solid powder will cause great wear to the valve during use, thereby reducing the overall sealing performance of the evaporator, and further leading to a reduction in evaporation efficiency.
