The structure, working principle and advantages of the mesh belt automatic screen changer

The mesh belt type automatic screen changer is a new type of screen changing filter equipment. Its structure includes the filter body, heating and cooling devices, and an electric control system. The length of the filter screen is 10-20m, which can be customized according to users, and it can be produced continuously for several months. . The mesh belt type automatic screen changer adopts water-cooled sealing, no material leakage, no wear, heating and cooling are automatically controlled by the control system, flexible netting, no waste generation and other advantages.

The working principle of the mesh belt type automatic screen changer: The mesh belt type automatic screen changer adopts a water-cooled seal and uses melt pressure or time to control the movement of the screen. The distance and speed of the filter movement can be set freely. When the inlet pressure of the screen changer reaches the set value, the control system will automatically start the filter with a heating rod at the outlet end for heating. After the outlet end reaches the set temperature, the filter can automatically move to remove the impurities in the melt. The filter screen brings out the screen changer. At this time, the inlet pressure of the screen changer drops to the normal working value. At this time, the control system stops the heating of the electric heating rod at the outlet end, and the outlet end is filled with cold water to solidify and seal.

The function of the mesh belt type automatic screen changer: It is the same as the ordinary screen changer, mainly filtering impurities in the melt, improving the plasticization, homogeneity and compactness of the melt. The circulating water cooling system of Zhengzhou Bart's mesh belt automatic screen changer adopts a reverse osmosis non-scaling pure water cooling cycle closed system, which saves water and environmental protection, and no solid scale causes waterway blockage. Bart mesh belt type automatic screen changer is currently widely used in the production of high-quality, long-process products such as pelletizing, cast film, sheet, plate, optical fiber, and various wire drawing.

The advantage of the mesh belt type automatic screen changer: Compared with other types of screen changers, it does not need to stop the machine and frequently replace the filter, which reduces the labor intensity of workers, improves production efficiency, and also reduces the generation of waste; it During the screen change process, there is no fluctuation in material flow, no product deformation, and good quality stability.
