Filtering tank for multi-wire cutting machine

Abstract

The invention provides a filtering tank for a multi-wire cutting machine, and aims to solve the problem that when conventional steel wires are cut, many solid impurities exist in water. The filtering tank for the multi-wire cutting machine comprises an outer bracket, a tank body, an upper cover, an inner bracket, a first filter screen and a decompression valve, wherein an opening is formed in the upper part of the tank body; the upper cover is hermetically connected to the opening of the tank body in a buckled manner; a water inlet is formed in the side wall of the tank body; a water outlet is formed in the bottom of the tank body; a cavity body is arranged in the tank body; the inner bracket is arranged in the cavity body of the tank body; the first filter screen is arranged on the inner bracket; the first filter screen is arranged on the inner bracket; the decompression valve is arranged on the upper cover; pressing blocks for pressing the upper cover on the tank body are connected to the outer side wall of the tank body in a rotatable manner. Through the adoption of the filtering tank disclosed by the invention, water for processing can be filtered; besides, the water can be recycled, so that water is saved and convenient to filter; the decompression valve facilitates the control of the air pressure in the tank body; through the adoption of the pressing blocks, the upper cover is convenient to fasten on the tank body.

Description

technical field [0001] The invention relates to a filter pot for a multi-wire cutting machine. Background technique [0002] The production of silicon wafers used to be cut by steel wire-loaded mortar before, but now it is directly cut by a special gold-steel wire with water. This technology not only greatly shortens the production and processing time, but also improves the overall quality of the product. Production costs have also dropped significantly. The diamond wire cutting technology also has high requirements for water quality, not only requires pure water and additives, but also requires no solid small particles in the water. If there is a lot of solid debris in the water, the wire mesh will easily bring the debris to the main roller during cutting, which will cause skipping and lead to a high probability of wire breakage, and the solid debris will adhere to the seam of the silicon rod so that the water cannot reach the cutting area, prone to disconnection and a la...
