Ph automatic continuous detection device

Abstract

The invention relates to a pH automatic continuous checking device. The existing device has the disadvantages of manual cleaning and complex operation. The side wall of a checking slot of the invention is provided with a liquid inlet and a liquid outlet, and the bottom part is provided with an ultrasonic generator. A current stabilizing hood is arranged in the checking slot, and the side wall is provided with a liquid circulating hole. A checking electrode passes through a lid cover to extend into the current stabilizing hood. A liquid entering pipeline is communicated with the liquid inlet by a liquid inlet valve, a liquid outlet pipeline is communicated with a liquid outlet by a liquid outlet valve, and the liquid inlet end of the liquid inlet valve is connected with the liquid outlet end of the liquid outlet valve by a by-pass pipeline which is provided with a by-pass valve. The device of the invention uses ultrasonic waves for cleaning, no direct impact is generated on the fragile pH glass checking electrode, and the glass electrode can not be damaged. When the pH automatic continuous checking device is cleaned, the checking electrode is not required to be detached, and thus, the cleaning is convenient and simple; the by-pass pipeline is opened in the cleaning of the pH automatic continuous checking device, and the producing process can not be interrupted.

Description

technical field [0001] The invention belongs to the technical field of electrochemical detection, and in particular relates to an automatic and continuous pH detection device which can be cleaned online. Background technique [0002] pH detection is essential for the detection of liquid acidity and alkalinity in the fields of chemical reaction and environmental detection. During the detection process, the surface of the pH electrode will be affected by the liquid to be detected, and gradually form a film composed of dirt. This film hinders the penetration of ions in the liquid to the glass electrode, and the pH electrode can no longer perform normal detection. The traditional solution is to manually remove the pH electrode from the device, and use a brush to clean the surface of the glass electrode to remove dirt. [0003] The disadvantages of the traditional method are: the glass head of the electrode is easily broken during disassembly and cleaning; after the electrode i...
