Description

Technical Field

[0001] The present invention relates to the technical field of medical waste treatment, and in particular to a tool monitoring method and system based on non-incineration friction heat medical waste treatment equipment. Background Art

[0002] In the medical field, the treatment of medical waste has always been a vital link that requires strict management. Traditional medical waste treatment methods, such as incineration and landfill, may not only pollute the environment, but also pose a risk of cross-infection, threatening public health safety. Therefore, it is particularly important to explore more environmentally friendly and efficient medical waste treatment technologies. In recent years, medical waste treatment equipment based on non-incineration friction heat has emerged, providing a new solution for the harmless and resource-based treatment of medical waste.

[0003] The working principle of this type of equipment mainly relies on the frictional heat effect. Specifically, there is a high-speed rotating tool system inside the equipment. When the medical waste is put into the processing chamber, the tool system cuts, tears and grinds the waste. The friction heat generated in this process can instantly increase the temperature of the waste, thereby achieving the effect of sterilization and decomposition of organic matter. Compared with traditional methods, non-incineration friction heat treatment technology has significant advantages: first, the use of friction heat has significant energy-saving effects; second, the heat generated during the treatment process can be directly used for sterilization and reduction of waste, and the treatment efficiency is high; third, it avoids harmful gases and smoke generated by incineration, which is environmentally friendly; fourth, the treated products are easy to be used as resources in the future, such as making biofuels or fertilizers.

[0004] However, in actual application, this type of equipment also faces some technical challenges, among which the life of the tool is particularly prominent. Due to the complex composition of medical waste, including plastics, paper, metals, glass, biological tissues and other materials, the tool needs to withstand great mechanical loads and thermal stresses during the processing, and is prone to wear and damage. Frequent replacement of tools not only increases operating costs, but may also cause equipment downtime or reduced processing efficiency due to improper tool change operations, thereby affecting the stability and continuity of the overall processing process.

[0005] Therefore, how to accurately monitor the use status of the tool, timely predict and replace the tool that has reached the end of its life, has become a key technical issue in improving the performance and reliability of non-incineration friction heat medical waste treatment equipment. In the prior art, although there are some tool replacement strategies based on experience or simple counting, these methods are often difficult to accurately reflect the actual wear of the tool, resulting in either premature tool replacement, resulting in waste, or untimely replacement, affecting the normal operation of the equipment.

[0006] In view of this, the art needs a tool monitoring method and system based on non-incineration friction heat medical waste treatment equipment to solve the above problems. Summary of the invention

[0038] Based on the problem pointed out in the background technology that the knives of the friction heat medical waste treatment equipment in the prior art rely on experience or simple counting and cannot accurately predict the wear of the knives, resulting in deviations in the timing of tool replacement. The present invention provides a tool monitoring method and system based on non-incineration friction heat medical waste treatment equipment, aiming to enable the friction heat medical waste treatment equipment to accurately calculate the replacement timing of its knives, thereby avoiding waste caused by premature replacement of knives and untimely replacement affecting the normal operation of the equipment.

By calculating the difference between the theoretical service life of the tool and the actual life loss, this difference represents the remaining service life of the tool. By comparing the difference with the preset value, it can be determined whether the degree of wear of the tool is close to the degree that needs to be replaced.

Through such a setting, on the one hand, it avoids the waste of resources caused by premature replacement of tools, and prevents equipment failure and reduced processing efficiency due to excessive wear of tools, maximizes the use of tool life, and reduces equipment operating costs; on the other hand, timely replacement of severely worn tools ensures the quality and effect of medical waste treatment, and prevents the reduction of processing efficiency and quality due to frictional heat generation and transfer affected by tool wear. In addition, this method realizes intelligent monitoring and management of tools, reduces the need for manual intervention, and operators can replace tools in time according to system prompts, thereby improving work efficiency and management level.
