Centrifugal filtration mechanism of multi-wire sawing machine

Abstract

The invention provides a centrifugal filter mechanism of a multi-wire cutting machine, which includes a filter system and a liquid receiving vehicle. The filter system and the liquid receiving vehicle are connected by screws. The filter system includes a liquid bucket, an outer bucket, a motor, Small pulley, V-belt, rotating shaft, large pulley, the liquid barrel is fixedly connected to the outer barrel, the outer barrel is built into the inner barrel, the inner barrel has a interlayer built-in felt, the motor is connected to the small pulley, and the The small pulley drives the large pulley through a V-belt, and the liquid bucket is connected to the large pulley through a rotating shaft. The filtration system and the liquid-receiving vehicle of the present invention can be separated, and it is convenient to clean the inner barrel. The filter system uses a motor to drive the small pulley, and then drives the inner barrel through a V-belt and a large pulley, and rotates at a high speed to separate the liquid and solid particles in the cutting fluid, so that Cutting fluid can be recycled.

Description

technical field [0001] The invention relates to the field of multi-wire cutting machines, in particular to a centrifugal filter mechanism of a multi-wire cutting machine. Background technique [0002] Multi-wire cutting machine is currently the main equipment for processing hard and brittle materials such as monocrystalline silicon, polycrystalline silicon, electronic grade silicon, and sapphire. The feed system is one of the main components of the equipment. During the operation of the multi-wire cutting machine, most of the metal to be cut is dispersed and suspended in the working fluid as spherical solid particles, generally with a diameter of several microns, and the oil in the mechanical transmission part of the multi-wire cutting machine also flows to the working fluid tank. , The purpose of the filter device is to filter out these things, keep the working fluid in a suitable state, and meet the needs of wire cutting work at all times. Excessive solid particles will a...

AI Technical Summary

Problems solved by technology

Excessive solid particles will affect the cooling and lubricating effect of the cutting fluid, thereby affecting the quality of processing; in addition, the cutting fluid cannot be recycled and must be replaced with new fluid, and the discharge of waste fluid will bring pressure to pollution control

At present, the multi-wire cutting machines on the market use ordinary filter screens for filtering, and the effect is poor.
