Brine water separation device in hot cleaning tank in bearing heat treatment

Abstract

The invention relates to the technical field of shaft sleeve part processing and particularly relates to a brine water separation device in a hot cleaning tank in bearing heat treatment. The brine water separation device comprises a main tank body, a float ball limiting pipe, a pure brine water absorption pipe, a quenching salt tank, a brine mixed liquid suction pipe, a vapor cooling device and a hot washing water tank. A water pump in the hot washing water tank is connected to the upper part of the main tank through the brine mixed liquid suction pipe with a valve, one end of the pure brine water absorption pipe extends into the bottom of the main tank body, the other end of the pure brine water absorption pipe stretches out of the main tank body and reaches to the quenching salt tank, the top of the main tank body is connected to the vapor cooling device through a vapor inlet, the bottom of vapor cooling device is connected to one end of a condensate outlet pipe, the other end of the condensate outlet pipe extends to a position above the hot washing water tank, the float ball limiting pipe is arranged in the main tank body, the side wall of the float ball limiting pipe is provided with brine water inlet holes and a float ball is arranged in the float ball limiting pipe. The brine water separation device does not need a special device and realizes automatic repeated recycling.

Description

technical field [0001] The invention relates to the technical field of shaft sleeve parts processing, in particular to a salt water separation device in a heat cleaning tank during heat treatment of bearings. Background technique [0002] In the heat treatment process of bearings, after high-temperature treatment of bearings and their parts, processes such as heat preservation, air cooling, hot cleaning and cold cleaning are required. Thermal cleaning is the first process in the cleaning process of bearings and their parts. During the cleaning process, the surface of bearings and their parts will have a mixture of salt residue and salt water. After a long time, there will be a large amount of salt water in the hot cleaning water tank. mixed solution. The equipment works for a long time, and the cleaning of the bearing and its parts cannot achieve the ideal cleaning effect. At this time, it is necessary to shut down the equipment line and replace all the previously stored br...

AI Technical Summary

Problems solved by technology

The equipment works for a long time, and the cleaning of the bearing and its parts cannot achieve the ideal cleaning effect. At this time, it is necessary to shut down the equipment line and replace all the previously stored brine mixture, which will delay production and cause relatively small costs. In addition, because the brine in the bearing heat treatment process contains industrial salts (sodium nitrate, potassium sulfate, etc.), if the brine mixture in the hot cleaning tank is randomly removed, it will have an impact on the environment
