AI Technical Summary
Technical Problem
The existing methyl silicone oil filtration process is prone to filter clogging, resulting in low filtration efficiency. Replacing the filter requires machine shutdown, which affects production efficiency.
Method used
The crude methyl silicone oil solution is passed through a filter screen by a roller pressing method. The pressure of the conveying roller is controlled by adjusting the air pressure of the air compressor. The filter screen circulates on the conveying roller and the filter residue is cleaned at the tail end, avoiding the need for machine downtime for replacement.
Benefits of technology
It improves filtration efficiency, extends filter life, avoids filter wear caused by improper pressure, and achieves efficient and continuous production.

Abstract
The application discloses a filtering structure and device and process for refining methyl silicone oil in the field of methyl silicone oil preparation. The filtering structure comprises two groups of upper and lower conveying units rotatably arranged on a rack. The conveying units comprise conveying rollers, and the two groups of upper and lower conveying units are oppositely arranged and are both wound with filter cloths. The conveying rollers rotate to drive the filter cloths to rotate. The filter cloths are used for transporting methyl silicone oil crude liquid to be extruded and filtered at the upper conveying rollers and the lower conveying rollers. The conveying rollers are hollowly arranged and are provided with sliding grooves at intervals in the circumferences. Extrusion columns are slidably arranged in the sliding grooves and are slid along the radial directions of the conveying rollers. The interiors of the conveying rollers are connected with air supply mechanisms. The methyl silicone oil crude liquid is pressurized by means of roll pressing so as to pass through the filter screen. The pressure of the conveying rollers can be controlled by adjusting the air pressure, so that the conveying rollers can be suitable for different working conditions and the filtering efficiency is improved. The filter screen is cleaned at the tail end of the filter screen conveying, and the filter screen does not need to be replaced during shutdown.
