Embodiment Construction

[0015] The present invention will be further described below with reference to the accompanying drawings and in conjunction with the embodiments.

[0016] An online detection device for the pH value of the papermaking production line is applied to the papermaking production line, and can provide real-time data of the pH value of the system to the control system, and the system can technically adjust the pH value based on these data, so that the system is at an optimal pH value within range.

[0017] refer to figure 1 , the pH online detection device of the present invention mainly includes a pH sensor 1, a pH transmitter 2, an IO module 3 and a central control computer 4.

[0018] The pH sensor 1 is used for sampling and detection, and its location needs to be selected after careful study. After long-term tests and data verification, the present invention thinks that the optimal setting position of the pH sensor 1 is on the white water tray. This position has no factors affe...

Abstract

The invention discloses an online pH value detection device for a papermaking production line. The device comprises a pH sensor, a pH transmitter, an IO (input / output) module and a central control computer, wherein the pH sensor comprises a detection head and a metal sleeve, a bolt is welded and fixed to the detection head, and the detection head is fixedly connected with the lower end of the metal sleeve through the bolt; the lower end of the pH sensor is inserted into a plain-boiled-water disc, the pH sensor fixedly penetrates the top surface of the plain-boiled-water disc through a fixing lug arranged on the metal sleeve. The online detection device disclosed by the invention can accurately detect the pH value in a papermaking production line system in real time without manual operations, and the system can adjust the pH value in time based on the detected value to ensure that the pH value is maintained within an appropriate range, therefore, the quality of products is guaranteed.

Description

technical field [0001] The invention relates to the technical field of papermaking production line equipment, in particular to an online pH value detection device for a papermaking production line. Background technique [0002] The pH value of the paper production system is an important indicator in the production process. It has gradually become a consensus to keep the pH value stable at 7.5-8. The stable pH value in this range is conducive to beating, improving the physical properties of base paper and preventing dust from resin solidification. To ensure a stable pH, continuous pH monitoring of the production system is required. At present, pH value detection is generally carried out manually, which has the problems of dangerous operation, large detection error, and poor real-time effect. Contents of the invention [0003] Therefore, the present invention provides an on-line detection device for the pH value of a paper production line, which can accurately detect the pH...
