Embodiment 1

[0023] Such as figure 1 As shown, an on-line pH sampling and measuring device for slurry materials in this embodiment consists of a fixed pin 1, a pH meter 2, a fixed flange 3, a fixed assembly 4, a keel frame 5, a filter cloth 6, an electric vacuum Air extraction valve 7, electric compressed air valve 8, measuring cavity 9, intelligent instrument 10 and intelligent time relay 11 etc. are composed.

[0024] The measuring cavity 9 in this embodiment is a cavity structure with a bottom opening, the pH meter 2 is inserted from the top of the measuring cavity 9, and is fixed inside the measuring cavity 9 by the fixing pin 1, and the measuring end of the pH meter 2 is located at At the lower opening of the measuring chamber 9, the above-mentioned pH meter 2 is connected with the smart meter 10. The pH meter 2 converts the measured filtrate pH signal into an electrical signal, which is amplified by an amplifier and transmitted to the smart meter 10 to display the pH value.

Abstract

The invention discloses an on-line pH (Potential of Hydrogen) value sampling measurement device for a slurry material, belonging to the technical field of sampling measurement. A pH meter is fixedly arranged in a measuring cavity through a fixed pin and is connected with an intelligent instrument; a filtrate pH signal measured by the pH meter is converted into an electric signal, and the electric signal is amplified and output to the intelligent instrument to display a pH value; an opening in the lower part of the measuring cavity is fixed with a keel frame through a fixed flange; a side wall of the keel frame is provided with a hole; filter cloth is fixedly arranged outside the keel frame through a fixing component; the fixing component comprises a fixing forage and a fastening pin; an electric vacuum extraction valve and an electric compressed air valve are arranged on the measuring cavity; and opening and closing of the electric vacuum extraction valve and the electric compressed air valve are controlled by an intelligent time relay. After long-term use, the problem of scaling is not caused on an electrode head of the pH meter, the measuring accuracy of the pH meter is kept at a higher level all the time, the service life of the pH meter is long, and the entire device can operate stably for a long time.

Description

technical field [0001] The invention belongs to the technical field of sampling and measurement, and more specifically relates to an online pH value sampling and measuring device for slurry materials. Background technique [0002] In the industrial production process, due to the requirements of the process, it is necessary to control the pH value of the solution within a certain range to meet the production needs. There are many forms of online pH meters at home and abroad. In industrial production, different forms of pH meters are selected due to the difference in material composition and working environment. For materials with high solid content such as suspension materials, emulsion materials or ore pulp, after a period of use, the pH electrode tip will be stuck or a layer of scaling will be formed on the electrode tip, so that accurate pH cannot be obtained. Value feedback brings inconvenience to industrial production, and it is even more inconvenient to be used in auto...
