Embodiment Construction

[0016] An automatic cleaning method for a liquid metering and feeding device, used for automatic cleaning of the liquid metering and feeding device, comprising the following steps:

[0017] (1) Set the height of the upper water level sensor and the lower water level sensor in the transparent casing on one side of the metering tank;

[0018] (2) Open the water inlet electromagnetic valve between the water storage tank and the metering tank, add liquid to the water storage tank, stop adding liquid when the upper water level sensor detects liquid, and open the water outlet electromagnetic valve for feeding;

[0019] (3) When the lower water level sensor detects no liquid, close the water outlet solenoid valve, open the water inlet solenoid valve and repeat steps (1) and (2);

[0020] (4) When the interval between the upper water level sensor detecting liquid and the lower water level sensor not detecting liquid exceeds a certain limit, determine whether the current time exceeds 5...

Abstract

The invention discloses an automatic cleaning method of a liquid metering and adding device, and aims at automatically cleaning the liquid metering and adding device. The method comprises the steps of setting the height of an upper water level sensor and a lower water level sensor; opening a water inlet solenoid valve to add liquid; stopping adding the liquid when the upper water level sensor detects the liquid, and opening a water outlet solenoid valve to add liquid; closing the water outlet solenoid valve and opening the water inlet solenoid valve when the lower water level sensor cannot detect the liquid; determining that the current time exceeds a certain time when the time interval between the time that the upper water level sensor detects the liquid and the time that the lower water level sensor cannot detect the liquid exceeds a certain of limitation; determining whether the lower water level sensor can detect the liquid; if not starting an automatic cleaning device. With the adoption of the method, the liquid metering and automatic adding device can be automatically cleaned; in addition, the device is cleaned at the time close to the closing time; therefore, no water is accumulated in a water storing tank for next use, and the influence on the agent concentration can be avoided.

Description

[0001] technical field [0002] The invention relates to an automatic cleaning method for a liquid metering and feeding device. Background technique [0003] In large-scale chemical production, it is necessary to automatically add liquid reagents through a liquid metering automatic feeding device. However, many liquid reagents are corrosive and adhesive, so the feeding device needs to be cleaned frequently. However, daily cleaning will cause the machine to stop working for a period of time, resulting in a reduction in production efficiency. Contents of the invention [0004] The object of the present invention is to provide an automatic cleaning method for a liquid metering and feeding device. [0005] In order to achieve the above object, the present invention adopts the technical solution as follows: [0006] An automatic cleaning method for a liquid metering and feeding device, used for automatic cleaning of the liquid metering and feeding device, comprising the foll...
