3.Slurry concentration measurement and control systemPulp concentration regulator Model:H18441

1、 Overview:

1. System Introduction:

H18441The automatic measurement and control system for pulp concentration is a generation of pulp concentration measurement system, which is used to replace the previously used knife type with low sensitivity and poor stability(including static and dynamic knives) and cone type external rotation concentration adjustment.

The characteristic of this system is high measurement and control accuracy, which can accurately measure and control the concentration of pulp, thereby stabilizing paper quantification. Multiple paper mill applications have shown that this system is significantly better than other types of pulp concentration regulators in terms of technical performance and usage effectiveness. .

H18441The automatic measurement and control system for slurry concentration has strong applicability, stability, and reliability. Many systems have been successfully applied in situations where concentration applications have failed in the past, such as corrugated paper with low beating degree, box board pulp, etc. The quantitative stability effect of using this system for cultural pulp and news pulp with high beating degree.

The system has a compact structure, small size, short installation and debugging time, and basically does not affect production during installation. Therefore, installation can be carried out by taking breaks during shutdown, which is easy to operate and use, with fast and stable concentration adjustment speed and strong anti-interference ability. Can operate continuously and stably for a long time without human monitoring.

2. System composition and functions of each component:

The concentration measurement and control instrument consists of four parts: concentration transmitter, slurry collection cylinder, electric control valve, and main unit. The main unit is based on the single-chip computer of Intel Corporation in the United States, using sensing and self-control technology, and integrating electromechanical information processing. The system can continuously detect the concentration of slurry in the slurry pipeline online, and the concentration signal is sent to the computer (main unit) by the concentration transmitter. The computer processes the concentration signal sent and eliminates various interference signals. The actual detected concentration value is calculated according to a certain conversion relationship, and compared with the set concentration value according to the process requirements. The opening and closing degree of the electric valve is automatically adjusted according to the deviation, thereby adjusting the dilution water volume and achieving the purpose of stabilizing and adjusting the concentration of slurry at the outlet of the slurry pipeline. This system controls the concentration of the slurry by adjusting the dilution water volume, so it can only dilute higher concentration slurry to the required concentration of the process, and cannot concentrate slurry below the required concentration of the process.

1) The pulp sampling cylinder consists of an inlet cylinder, a return cylinder, and a shut-off valve, and is made of stainless steel. The function of the pulp inlet cylinder is to take a path of pulp for the sensor to measure pulp concentration. The function of the slurry return cylinder is to allow the slurry to flow back into the slurry circulation system. The function of the shut-off valve is to control the flow rate and flow rate of the slurry in the pipeline.

2) The sensor consists of a stainless steel casing, a drive motor, a speed measurement electronic circuit, and an impeller. The stainless steel casing and its sealing components, as well as the oil seal design, are important benefits for the sensor to function properly in harsh environments. Drive the motor to achieve high standards for the lifespan and reliability of the sensor. The electronic circuit for measuring rotational speed is used to acquire and transmit electronic signals. The impeller is used to obtain signals of pulp concentration changes

3) The host is composed of a chassis, a display, and internal electronic circuits. The chassis is small and lightweight, easy to install, and the monitor is used to display pulp concentration and valve opening.

4) The regulating valve is used to control the amount of water added to the pulp path, in order to achieve concentration control of the pulp in the pulp path.

5) Connecting cables are used to achieve signal transmission between the host and sensors, as well as between the host and regulating valves.

3. Scope of application:

The concentration measurement and control instrument is mainly suitable for various stages of pulp concentration measurement and control in the pulp and paper process of papermaking enterprises.

(1) The regulation of pulp concentration in the pulp conveying pipe between the pulp tank and the stabilizing tank is used to stabilize the pulp concentration, thereby stabilizing the amount of pulp discharged and achieving the goal of stable paper production.

(2) Used for measuring and controlling the slurry concentration before the disc mill to improve the quality and yield of the pulping machine.

(3) Used for measuring and controlling the concentration of slurry before the three-stage tower float, to stabilize production, reduce costs, and minimize pollution.

(4) Measurement and control of pulp concentration during the transportation of pulp from the pulp making workshop to the papermaking workshop.

4.Dip Coater/Vertical Pulling Machine/Pulling Coating MachineH18440

oneProduct application

This product is mainly used for sol-Thin film materials were prepared by liquid phase methods such as gel method. Immerse the clean and dry substrate into a solution (sol), and vertically lift the immersed substrate at a certain speed using pre-set parameters. A layer of film is attached to the substrate, which is called "wet gel film". With the evaporation of solvent in the "wet gel film" film, the film is solidified on the substrate into a "dry gel film". After further drying and high-temperature heat treatment, the "dry gel film" can obtain the required nano film materials. The thickness of the film layer is determined by the pulling speed, liquid concentration, and liquid viscosity.
