Structure, principle, advantages, and configuration of hydraulic screen changer for sheet metal extrusion (single column hydraulic screen changer)
Single column hydraulic screen changer structure
The single column hydraulic screen changer is composed of basic components such as the main body, column body, hydraulic cylinder, filter block, and safety protection cover of the screen changer. There are two filtering channels on the column of the screen changer, which are equipped with filter blocks. Under the action of the hydraulic system, the two filter blocks can alternately enter the working position and the screen changer position.
Working principle of single column hydraulic screen changer
It uses high-performance steel and special processing and heat treatment methods, with dual filtering channels working alternately, and the screen changes quickly, making it easy to produce and maintain. It has two filtering stations on a column, one working and one standby. When the filter screen needs to be replaced, the hydraulic device is activated to quickly switch between stations, pushing out the dirty screen station and entering the standby station to complete the process of changing the screen.
Application of single column hydraulic screen changer
A high-end screen changing filtration system developed specifically for extrusion production users, particularly suitable for the melt filtration requirements of high-level automated production lines. Suitable for the production of recycled granulation, cast film, blown film, sheet metal, sheet metal, pipe, wire drawing, polished rod, cable and other products. Applicable raw materials include: PP, PE, ABS, PS, PET, PVB, PBT, TPE, PMMA, PC, Pa, etc.
Performance characteristics of single column hydraulic screen changer
Adopting a rigid sealing structure, the seal is reliable and leak free; It can meet the high extrusion production of the vast majority of polymers and be used in conjunction with extruders of different standards.
Equipped with a material filling and exhaust structure, the screen can be changed without stopping the machine, without material leakage, ensuring that the screen change does not interrupt production.
The filter design with high wear resistance, high pressure resistance, and high precision improves the effective area and quality of filtration.
At a pressure of 35MPa and a temperature below 350 ℃, its performance will not be affected.
We can provide customers with standard configurations and special processing according to actual requirements.
