Device for reducing volume of emulsion liquid-feed main tank of rolling mill and method thereof

Abstract

The invention relates to a device for reducing volume of an emulsion liquid-feed main tank of a rolling mill and a method thereof, which are used for reducing the volume of a liquid-feed main tank of a system and reducing the discharge of disposable oily emulsified wastewater. The device comprises a plurality of valves, a plurality of magnetic filters and a plurality of liquid-feed main tanks, wherein the magnetic filters are connected with an emulsion return pipe; the liquid-feed main tanks are connected with the emulsion liquid-feed pipe; a plurality of magnetic filters are connected in parallel and then are optionally connected with the liquid-feed main tanks; and the connection pipes arranged between the magnetic filters and the liquid-feed main tanks are respectively provided with a valve. The method adopting the device comprises the following steps: carrying out liquid feeding through the emulsion in one or two liquid-feed main tanks; adopting the device by opening the pipe valve, communicating three magnetic filters with the main liquid-feed tanks; and opening the valve on the return pipe after a start-up main pump is started, then feeding the emulsion in the system after being processed by the magnetic filters in the liquid-feed main tanks; and carrying out the steps of recycling and the like. The invention has the advantages of reduced system occupied area, reduced floor area of emulsion, reduced tank volume, reduced waste water discharge and treatment cost and the like.

Description

technical field The invention belongs to the field of liquid supply systems for rolling mills in metallurgical manufacturing, and in particular relates to a device and method for reducing the volume of a main tank for emulsion supply of rolling mills. Background technique At present, in the emulsion circulation system of the rolling mill, the liquid supply main tank is an important equipment for the supply and storage of the emulsion, and it is also the equipment with the largest volume in the whole system. has a very important role. The rolling mill emulsion mainly goes through the following processes in the process of recycling: As shown in Figure 1, circulation box 21→liquid supply pump 22→cooler and liquid supply pipeline 23→jet frame 24→collection tank 25→liquid return tank 26→vacuum filter 27→magnetic filter 28→circulation box twenty one. In Figure 1, during the circulation of the emulsion, the volumes of the corresponding equipment and pipelines are as follows: ...

AI Technical Summary

Problems solved by technology

The present invention provides a device and method for reducing the volume of the emulsion supply main tank of a rolling mill. Large size, large floor area, large plant, large discharge of waste water at one time, etc., through the connection of the pipeline valve between the equipment and the main tank, the volume of the system liquid supply main tank can be greatly reduced to meet the system volume Need, convenient control, simple operation and easy maintenance
