As the development of the papermaking industry has entered a new era, technological innovation, cost reduction and efficiency improvement, high-quality development, automation, and dataization have become the common goals of the papermaking industry. At the same time, due to the gradual advancement of solid waste policies, papermaking raw materials in 2021 are still a problem that the papermaking industry must face.

Since the raw materials of the papermaking industry are mainly recycled paper, wood blocks, bamboo chips, and straw, moisture detection has become a top priority for reducing costs during the acquisition process. The automated detection solution centered on the online microwave moisture of the whole vehicle has gradually replaced the traditional visual inspection method, bag-drawing and drying method, and pin insertion method. Take the example of sampling and drying: one to two kilograms of samples are extracted from 2-3 bags of recycled paper in the whole vehicle, and then dried in the drying room. After 3-4 hours of drying, the moisture content is calculated through data, which represents the moisture value of all batches.

The results of this small amount of sampling test cannot represent the overall moisture content. There is artificial contingency, which creates a cost black hole and increases invisible costs.

In response to this pain point, Shandong Rich Zone Intelligent Technology Co., Ltd. launched an intelligent full-process cost control solution that can meet the three requirements of automation, dataization, and intelligence in the whole process from vehicle registration, vehicle reservation, regional pricing, vehicle queuing, vehicle entry and exit, weighing and metering, moisture, impurities, miscellaneous paper dataization, raw material grading, and docking with the financial system.

Through Rich Zone's full-process overall solution, the whole process of raw material cost control can be systematically operated, and every necessary link can be effectively controlled, which improves management efficiency and makes every important link have data to follow; optimizes the acquisition quality inspection management process, greatly reduces costs; controls human factors, and makes the acquisition process more fair and just.

At present, Rich Zone's full-process systematic solution has been applied by many companies across the country, and the market effect feedback is excellent.

Water is a polar molecule. When microwaves (AC electromagnetic waves) pass through water molecules (H2O), polarization reactions will occur. Polarization reactions will make microwaves do work, and work will generate (heat) energy. Energy dissipated is energy loss.

The principle of the whole vehicle microwave moisture meter is to calculate the percentage of moisture content of the whole vehicle based on the microwave energy loss generated when microwaves penetrate the medium combined with the height, width, temperature and humidity compensation algorithm.

The new product adopts the self-developed high-end transceiver control module and adopts a two-way transceiver mode. There are three sets of antenna arrays on both sides in the vertical direction for data transmission and reception, which is equivalent to the original 6 devices working simultaneously.

This technology can be used for regional positioning of recycled paper bags, which is more accurate, visual and automated.

Applicable to papermaking, wood board, and biomass industries.

(1) 100% whole vehicle recycled paper measurement:

Using multi-frequency microwave transmission scanning measurement method and using the narrow beam angle of the antenna, it realizes the truly fully automated online detection of the water content of the whole vehicle paper.

(2) Automatic adjustment of the starting measurement position of the vehicle model:

Automatically locate the scanning starting position according to the selected vehicle model database to ensure that the equipment starts detection from the recycled paper position;

(3) Regional positioning of recycled paper packages:

Automatically detect the end boundary and display the moisture content distribution map of each section in the paper package area. It can distinguish which package on the main driver and co-driver sides of the vehicle has a large amount of moisture, and realize visualization through software.

(4) Intelligent upgrade algorithm:

Adopting the artificial intelligence self-learning and self-calibration model, by inputting the test calibration value, the system automatically forms the relationship expression between the measured data and the moisture content. The system can realize self-learning and long-term use after one calibration.

1. The length, width and height of the equipment are: 20*5*5 meters;

2. Operation mode: When the vehicle enters the moisture detection area and stops, press the start button, and the equipment scans the entire vehicle of recycled paper at a uniform speed of 40cm/s from the front position of the vehicle. Taking a 17.5-meter recycled paper vehicle as an example, it takes 43 seconds to complete the measurement. After the measurement is completed, the data is automatically connected to the required docking system;

3. After the measurement is completed, the vehicle can leave the recycled paper detection area. Automatic uniform scanning can avoid the influence of unstable vehicle movement speed on the measurement data.

① Time saving: Automatic detection of the moisture content of the whole vehicle of recycled paper is realized, and the moisture content of a vehicle is completed in about 40 seconds;

② Manpower saving: The full set of detection equipment only requires one operator to complete all the work. If the loading meets the standardization requirements, the intelligent unmanned operation mode can be realized, and no subsequent moisture measurement personnel are required, which can reduce the number of quality inspectors for the factory.

③ Worry-free: The reliability of the test equipment data realizes fair, just and effective data supervision between suppliers and buyers, and can avoid conflicts between the supply and purchase parties, so that the moisture data of each vehicle can be traced

④ Save money: The moisture of the whole vehicle recycled paper is automatically operated, which is extremely safe, without human intervention, and the data is fair and just.

The fully automatic whole vehicle raw material microwave moisture monitoring system solution not only improves the accuracy of the test data, but also provides a basis for analyzing and solving existing problems; it also provides intuitive test data for operation, further improves the accuracy of the test, streamlines labor, avoids errors caused by human operation, has low maintenance costs, and has immeasurable direct and indirect economic benefits. At the same time, the solution is in line with the national integration plan of industrialization and information technology, and widely applies electronic information technology to all aspects of industrial production, drives industrialization with informatization, promotes informatization with industrialization, and launches positive industrial applications to make it a hot spot for industry development, in order to achieve production automation, product intelligence, industrial advancement, refined management, data visualization, improve production efficiency, reduce operating costs, enhance corporate competitiveness, and pursue sustainable, low-carbon, and green development.
