Embodiment

[0054] Such as figure 1 As shown, the rapid pulp kappa number tester of the present invention includes a reaction tank 2, three liquid addition units communicated with the reaction tank 2 and having the same structure, and a magnetic stirrer 9 carrying the reaction tank 2. These three liquid addition units are divided into It is the first liquid addition unit 11, the second liquid addition unit 12, and the third liquid addition unit 13; distilled water, KMnO 4 solution, H 2 SO 4 solution; and every liquid addition corresponds to the corresponding volume, these three liquid addition units add the above three liquids to the reaction pool 2 in a sequential manner, wherein distilled water is used for blank control and cleaning device, KMnO 4 solution and H 2 SO 4 The solution is used to prepare the reaction solution. The stirring rotor 10 of the magnetic stirrer 9 is placed in the reaction tank 2. The function of magnetic stirring is mainly to make the reaction in the reaction...

Abstract

The invention discloses a rapid tester for a paper pulp kappa number and a control method of the rapid tester. The rapid tester comprises a reaction tank, three liquid adding units, a magnetic stirrer, a stepping motor, a sliding rail connected with the stepping motor, a slide block arranged on the sliding rail, an upper limiting switch, a lower limiting switch, a bracket fixedly connected with the slide block, a cuvette, a waste liquid tank, a peristaltic pump, a light source, a photovoltaic conversion device and a data displaying device, wherein the three liquid adding units are communicated with the reaction tank and are the same in structure; the magnetic stirrer is used for bearing the reaction tank; the peristaltic pump can be used for pumping liquid from the reaction tank to the waste liquid tank through the cuvette; light emitted by the light source passes through the cuvette and is received by the photovoltaic conversion device, and then the light is converted and conveyed into a single chip microcomputer; after the tester is electrified, self detection is carried out to ensure that the tester is at a normal initial state and simultaneously a power supply is driven to emit the light to pre-heat; before a sample to be detected is detected officially, blank deduction, base solution detection and standard sample detection operations need to be carried out firstly; after an experiment is finished, the device is washed.

Description

technical field [0001] The invention relates to the measurement of pulp kappa number in the pulping and papermaking process, in particular to a rapid pulp kappa number measuring instrument and a control method thereof. Background technique [0002] The pulp kappa number is an important control parameter in the pulping process, and it is also the basis for the amount of bleaching agent added in the subsequent bleaching process. Quickly and accurately measuring the kappa number of unbleached pulp will help to know the degree of cooking of raw materials in time, so as to adjust the cooking conditions accordingly. This has very important practical significance for optimizing pulping production, namely: improving the utilization rate of raw materials, ensuring the quality of pulp, saving energy and reducing emissions. At present, the commonly used method for determining the kappa number of pulp is still the traditional titration method (TAPPI-T236, SCAN-C1:77, ISO302). The infl...
