Embodiment 1

[0009] The first embodiment of the present invention relates to a scraping film technology in molecular distillation equipment, see figure 1 As shown, it includes: film scraping brush (1), connecting plate (4), connecting plate and film scraping brush are connected by bearing (3), cage-shaped cover composed of film scraping brush, bearing and connecting plate ( 5), the cylinder body (2), which is located outside the cage-shaped cover and has a certain gap with the scraping brush, drives the motor (6) of the scraping brush. The film-scraping brush and the cylinder keep a certain distance and do not touch each other to prevent the abrasion of the film-scraping brush; the elastic bristles of the film-scraping brush are dense, which can increase the area of ​​the liquid film, thereby increasing the material handling capacity; the film-scraping brush The elastic bristles are bent towards the side away from the rotation direction of the film scraper, which can increase the contact a...

Embodiment 2

[0012] The cage-shaped cover composed of scraping film brush, rotating bearing and connecting plate is fixed, and the cylinder rotates under the drive of the motor. The liquid material enters the molecular distillation equipment, and the material flows down the inner wall of the cylinder at a uniform speed through the liquid distributor. There is resistance when the liquid in the body wall and the scraping brush move relative to each other, which drives the movement of the scraping brush. The movement of the scraping brush can continuously refresh the liquid film, increase the area of ​​the liquid film on the bristles, and increase the material handling capacity .

Embodiment 3

[0014] The film scraping brush is connected to the connection plate, and the connection plate and the film scraping brush form a cage-shaped cover body, and the cage-shaped cover body is connected to the motor. There is a certain distance between the film-scraping brush and the inner wall of the cylinder. The difference from the first embodiment is that There is no rotating bearing connecting the scraping film brush and the connecting disc. The film-scraping brush is driven by the motor to make a turnover movement. There is resistance between the brush and the liquid on the inner wall of the cylinder, which can make the film-scraping brush rotate. While the brush is constantly updating the liquid film on the inner wall of the cylinder, it is also updating during rotation. The liquid film on the brush increases the evaporation of the liquid and has a strong material handling capacity.

Abstract

The invention relates to a film scraping technology, comprising a film scraping brush and a connecting tray, wherein the film scraping brush is connected with the connecting tray by means of a bearing. The film scraping technology also comprises a film forming barrel, a cage-shaped cover body and a motor, wherein the cage-shaped cover body is connected with the connecting tray and the motor; the film scraping brush is positioned in the barrel, and a certain gap is reserved between the film scraping brush and the barrel. The film scraping technology has the greatest advantage that the film scraping brush can revolve on the self axis depending on a certain resistance of a material while being driven to rotate by the motor, so that the film forming area is greatly enlarged, and the material treatment speed is greatly accelerated; when being used in industrial production, the technology can remarkably increase the production rate.

Description

technical field [0001] The invention relates to a molecular distillation device, in particular to a film forming technology of the molecular distillation device. Background technique [0002] Molecular distillation technology is a new distillation technology. Molecular distillation uses different mean free paths of different molecules to achieve the purpose of separating different components. Molecular distillation can reach the highest operating pressure of 5 mmHg, and the bubble point of the material is greatly reduced. Molecular distillation equipment is mainly used for the separation of liquid mixtures, especially heat-sensitive materials, materials with higher boiling points under normal pressure or materials with close boiling points. Because the processing capacity of molecular distillation is not as large as that of conventional distillation, the production cost is high. Generally speaking, molecular distillation is not considered for materials that can be processed...
