Description

one

A known apparatus for controlling and controlling the quality of pulp, comprising a sampler, a fractionation and a concentrate concentrate: measures, a saber stock meter, a computing device and an output unit, does not preclude the possibility of continuously monitoring and controlling the quality of pulp in the process of its production.

To enable continuous tiling and quality control of the pulp during its production, in the proposed installation, the sampler is connected via a fractionator to cancentrameters and a sausage sausage meter, the electrical outputs of which are connected to the input of a computing device connected to the output unit. and wood mass quality regulator.

The drawing shows a block diagram of the installation described, which consists of a sampler 1, a fractionator 2 of continuous operation, a concentrator of 3, 4 liters 5, a meter 6 cadrext of pulp, a computing device (WU) 7, an output unit 8. The sampler} is fed with wood. mass 9, which, after fractionator 2, is divided into k streams (three trays in the diagram), flows through concentrator 3, 4 and 5 and gauge 6 and returns to the technological note. Information on the signal panel is transmitted to channel 10, control commands via channel I.

The installation works as follows.

The pulp 9 sampler 1 selects for less than the total flow, cleans chips and is sharp, dilutes to the required concentration not more than 1% and feeds to fractionator 2. The fractionator separates the mass into fractions

by the size of its fibrous elements. The diagram shows the division into three fractions.n. The concentration of each fraction is measured continuously by concentration meters 3.4 and 5, dan) the first concentration values are sent to the VU 7. The VU also receives signals of sagascy from the meter 6. The VU processes the primary data on the concentration of each fraction and intermittent sagascy

fraction, calculates the value of the characteristics of L, S and p, where L is the average fiber length, S is the specific surface of the intermediate fraction, n is the indicator of the mass distribution along the fiber length and on the basis of them receives

the value of the main quality parameters of wood pulp. WU using the output unit channel 10 transmits information about the quality of the currently produced pulp to the signal board and delivers

via the channel // command to control the defibration procedure for obtaining wood pulp with given-quality parameters.

Subject invention

An installation for controlling and regulating the quality of wood pulp, including the following: bobborlka, fractionator, concentrators, sausage sappiness meter, computational device and output unit,

characterized in that, in order to enable continuous monitoring and control of the quality of wood maosa during its production, the sampler is connected through a fractionator to concentrator and sausality meter of the wood mass, the electrical outputs of which are connected to the input of the computing device connected to the output unit, the output of which is filed on the signal panel and the quality regulator pulp.
