Device for filtering metal components in sewage of grinding workshop

Abstract

The invention provides a device for filtering metal components in sewage of a grinding workshop, and belongs to the technical field of sewage treatment. The problems that metal components in sewage are filtered in an existing grinding workshop in the mode that a filter screen is installed at a sewage draining exit, although a filtering effect is achieved, sewage draining can be affected after long-time use, and the filter screen needs to be frequently cleaned manually are solved. The device for filtering metal components in sewage of a grinding workshop comprises a shell, a working cavity is defined in the shell, a water inlet is formed in the upper end wall of the shell, a water outlet is formed in the lower end wall of the shell, and a water storage mechanism is arranged in the water outlet. The device for filtering metal components in sewage of a grinding workshop is more convenient to use, labor-saving and better in filtering efficiency.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to a filtering device for metal components in sewage in a grinding workshop. Background technique [0002] The sewage in the grinding workshop can be mainly divided into indirect cooling water for equipment, direct cooling water for equipment and products, and waste water in the production process. Since the grinding workshop will produce a large amount of metal waste and scrap during production, with the circulation of the coolant in the machine tool, Part of the waste residue and waste chip is attached to the machine tool, and the other part of the waste residue and waste chip will be discharged along with the coolant. The discharged part will not only pollute the environment, but also contain more metal particles in the sewage, resulting in energy waste. , the existing grinding workshop mostly adopts the form of installing a filter screen at the sewage outlet to filter the...

[0002] The sewage in the grinding workshop can be mainly divided into indirect cooling water for equipment, direct cooling water for equipment and products, and waste water in the production process. Since the grinding workshop will produce a large amount of metal waste and scrap during production, with the circulation of the coolant in the machine tool, Part of the waste residue and waste chip is attached to the machine tool, and the other part of the waste residue and waste chip will be discharged along with the coolant. The discharged part will not only pollute the environment, but also contain more metal particles in the sewage, resulting in energy waste. , the existing grinding workshop mostly adopts the form of installing a filter screen at the sewage outlet to filter the metal components in the sewage. Although it has a certain filtering effect, the metal components will block the filter screen after long-term use, which will not only affect the sewage. discharge, and need to manually clean the filter frequently
