Separating and recycling equipment and method for magnetic mud in cutting waste liquid

Abstract

The invention relates to separating and recycling equipment and method for magnetic mud in cutting waste liquid and aims at multi-line cutting equipment. The separating and recycling equipment comprises at least one set of magnetic mud recycling mechanism, wherein the magnetic mud recycling mechanism comprises a motor, a rotary drum, a scraping knife and a separating and recycling mechanism; the rotary drum is connected with the output end of the motor to realize rotation; a plurality of magnetic sections and non-magnetic sections which are arrayed at intervals are arranged on the surface of the rotary drum; the scraping knife is fixedly arranged on the rotary drum and a knife head of the scraping knife corresponds to the surface of the rotary drum so as to scrape magnetic powder collected on the magnetic sections of the rotary drum to the non-magnetic sections; the separating and recycling mechanism is arranged besides the rotary drum to separate and recycle the magnetic powder collected on the non-magnetic sections of the rotary drum. With the adoption of the separating and recycling equipment and method for the magnetic mud in the cutting waste liquid, the magnetic powder in the cutting liquid is separated and recycled and the cutting liquid can be circularly utilized for a plurality of times when a grinding material silicon carbide does not need to be replaced, so that the aims of guaranteeing the product quality, improving the production efficiency and reducing the production cost are realized.

Description

technical field [0001] The invention relates to a separation and recovery device and a recovery method for cutting waste liquid, in particular to a magnetic mud separation and recovery device and a separation and recovery method for the cutting waste liquid of a multi-wire cutting device. Background technique [0002] Due to its superior performance of high precision, high efficiency and low loss, the multi-wire cutting machine has been widely used in the cutting and decomposition of various hard and brittle materials, and has won unanimous praise from customers. However, in the cutting and decomposition of rare earth permanent magnet materials, due to the inherent physical properties of magnetic materials, the cutting fluid becomes more viscous with the increase of cutting magnetic powder, and the magnetic powder dominates, occupying the working space of abrasive silicon carbide. , which leads to the reduction of slicing accuracy and production efficiency, forcing the produ...

However, in the cutting and decomposition of rare earth permanent magnet materials, due to the inherent physical properties of magnetic materials, the cutting fluid becomes more viscous with the increase of cutting magnetic powder, and the magnetic powder dominates, occupying the working space of abrasive silicon carbide. , which leads to the reduction of slicing accuracy and production efficiency, forcing the production plant to spend more than 1,000 yuan a day to change the cutting fluid when processing magnetic materials, and to increase production costs to ensure product quality, which limits the use of multi-wire cutting machines in magnetic The scope of application in the field of material processing, high-end products - such as speaker magnets, etc., due to their high quality requirements, their prices are also higher, acceptable for high-cost products; while low-end products - such as packaging magnets, luggage magnets, etc., Due to the high operating cost, we had to turn to the next best thing and use low-efficiency, high-loss products instead
