A device for recovering and reusing metal waste and waste liquid from mechanical processing

Abstract

The invention discloses a device for recycling and reusing machining metal waste and waste liquid. The processing unit includes a cleaning box, a drying kettle, and a suction filter pump. The present invention realizes the continuous operation of waste liquid treatment through the filter screen frame A and the filter screen frame B which work alternately up and down, and greatly improves the treatment efficiency. In addition, the backwashed waste water and residues are discharged into the metal waste cleaning box to realize the centralized and joint treatment of the mechanical processing waste liquid and waste, and also maximize the recovery of metal waste. Filtration can improve the recycling value of waste liquid. In a word, the present invention has the advantages of large processing capacity, high processing efficiency, high recycling rate of waste liquid and waste chips, and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a device for recovering metal waste and waste liquid from mechanical processing. Background technique [0002] Machining refers to the process of changing the shape or performance of a workpiece through a mechanical device. According to the difference in processing method, it can be divided into cutting processing and pressure processing. The production process of a machine refers to the entire process of making a product from raw materials (or semi-finished products). For machine production, it includes transportation and storage of raw materials, production preparation, blank manufacturing, processing and heat treatment of parts, product assembly, debugging, painting and packaging, etc. The content of the production process is very extensive. Modern enterprises use the principles and methods of systems engineering to organize and guide production, an...

Problems solved by technology

[0003] With the rapid development of the domestic economy, many mechanical processing factories have sprung up, among which metal products are particularly prosperous, metal processing factories have also ushered in expansion, and the resulting metal waste and waste liquid have also increased. Waste will pollute the environment of the processing plant to a large extent. For example, if the waste chips are piled together, because the waste chips contain oil, long-term stacking will cause permeable pollution to the soil, and also hinder the further utilization of metal waste chips

Most of the waste liquid belongs to the coolant in the metal processing process. In the prior art, most of the metal waste in the waste liquid is filtered and then discharged. Most of the coolant contains metal waste. Small solid particles such as residue and dust can only be used once, and the value of reuse is small. However, the direct discharge of this waste liquid not only pollutes the environment, but also causes a certain amount of waste

[0004] In the prior art, most of the metal waste and waste liquid are treated separately, and there are few integrated devices that combine the two for treatment.
