a feeding system

Abstract

The invention provides a feeding system, which includes a blending device, a feeding device and a circulation device arranged in sequence, a first valve is arranged between the blending device and the feeding device, and the circulation device is also connected to the blending device For realizing the circulation of the solution, the circulation device is also provided with a second valve, the feeding device includes a metering tank and a third valve arranged below the metering tank, and the metering tank is connected to the blending device and the metering tank through the third valve. Between the circulation devices, the feeding steps are as follows: when it is necessary to add soluble materials, close all valves, add soluble materials into the metering tank, and then open the first valve and the third valve to let the solution in the blending tank be flushed into the metering tank. The soluble material is initially dissolved in the tank, and then the second valve is opened to allow the solution to circulate for further dissolution. The feeding system of the invention has an ingenious and reasonable structure, and the method of dissolving soluble materials in advance effectively protects the circulation device from being stuck or blocked, has strong practicability, and is worth popularizing.

Description

technical field [0001] The invention relates to the field of chemical production, and mainly relates to a feeding system for adding soluble materials as raw materials, auxiliary materials or auxiliary agents into mother liquor to prepare a target solution. Background technique [0002] In the production process of existing chemical solutions, the addition of raw and auxiliary materials or additives, which are generally soluble materials, is usually directly added to the blending tank. Some raw and auxiliary materials or additives cannot be completely dissolved and directly enter the circulation pump, resulting in jamming. People need to add a feeding system that is more flexible, dissolves faster, and operates more stably, and this case arises from this. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a feeding system with reasonable structure, flexible addition, rapid dissolution and stable equipment operation f...
