Description

Technical Field

[0001] The invention belongs to the technical field of waste paper recycling, and in particular relates to a waste paper quality efficient intelligent detection system. Background Art

[0002] Some of the statements merely provide background art related to the present disclosure and do not necessarily constitute prior art.

[0003] As an important renewable resource, the recycling of waste paper has good economic and social benefits, is of great significance to environmental protection and resource utilization, and is one of the effective ways to solve the shortage of forest resources and papermaking raw materials in my country. The quality of waste paper directly affects the procurement cost of raw materials and the quality of subsequent pulping and papermaking. Therefore, it is necessary to effectively test and monitor the quality of the collected waste paper.

[0004] At present, papermaking enterprises mainly test the moisture content and ash content of waste paper raw materials according to national standards. Conventional methods are used for testing - drying in electric blast drying ovens and burning ash in muffle furnaces, which takes a long time and is inefficient. The content of plastic in the raw materials is determined based on the experience of the testers, which is greatly affected by human subjective factors and lacks objectivity. The patents on waste paper quality testing published by the State Intellectual Property Office mainly use microwave technology to test the moisture content of waste paper, and cannot test other indicators of waste paper raw materials. The patent "An automatic detection device and detection method for waste paper quality based on artificial intelligence" (publication number CN114669493 A) uses a microwave moisture meter to test the moisture content of waste paper packages, and uses a waste paper AI image recognition system to calculate the proportion of impurities. Not only does it require the waste paper packages to be processed separately, but the test indicators are not specific enough. There is an urgent need for an effective, intelligent and convenient waste paper quality detection solution. Summary of the invention

[0005] In view of this, the present invention provides a waste paper quality efficient and intelligent detection system. It can detect five quality parameters of waste paper packages, namely moisture content, ash content, plastic content, fiber content, and the ratio of mechanical pulp to chemical pulp. It includes a set of waste paper package drilling devices, a set of waste paper quality detection devices, a set of equipment motion control system, a main control computer, and a set of detection spectrum analysis system. The method of use is: the waste paper package is placed in a suitable position, and there is no need to separate the packages. It is only necessary to drill holes on the waste paper package, and then insert the detection probe for testing. The test results are sent back to the spectrum analysis system for analysis, and various indicators of the waste paper package can be obtained.
