Automatic PH detection and neutralizing apparatus of washing machine

Abstract

The invention discloses an automatic PH detection and neutralizing apparatus of a washing machine. The automatic PH detection and neutralizing apparatus comprises a circulating pipeline for realizing internal circulation of the washing machine, a feeding pipeline connecting the circulating pipeline and a feeding barrel, and a PH detection pipeline with both ends being respectively connected with the circulating pipeline; under the suction effect of a circulating pump, through the circulating pipeline, water inside the washing machine is filtered by a brush filter and is sprayed onto a fabric in the washing machine by controlling a plurality of spraying apparatuses, one part of filtered water enters the pH detection pipeline under the effect of the circulating pump, a PH value of the circulating water and the water can be monitored by virtue of a PH probe and a temperature probe in the PH detection pipeline, a measuring pump in the feeding pipeline is controlled to absorb acidic solution from the feeding barrel according to a difference to a set value, the acidic solution enters the brush filter to perform the PH neutralization, and the temperature of the circulating water is regulated by virtue of a cooling pipe, so that the real-time continuous automatic detection and neutralization can be realized.

Description

Technical field: [0001] The invention relates to a pH automatic detection and neutralization device for a washing machine. Background technique: [0002] In the traditional dyeing and finishing process, the pH value of the washing machine is usually detected manually with pH test paper or samples taken to the laboratory with special instruments, and then the corresponding acid is added artificially for neutralization. In continuous production, traditional detection There is hysteresis, resulting in unstable pH value and affecting product quality. Artificial detection and neutralization prolong the production process time, and the detection is unstable, resulting in many errors, which cannot meet the current needs of printing and dyeing companies for automation and waste resources. Invention content: [0003] The purpose of the present invention is to solve the problems in the prior art, to provide a method that eliminates the hysteresis caused by the traditional process d...
