Furthermore, the existing equipment cannot turn the crushed solid waste particles while drying them, resulting in low drying efficiency. Summary of the Invention

[0014] Furthermore, a conveyor is fixed to the top surface of the base. The conveyor is located below the mixing tank. An auxiliary part is installed on the conveyor. The auxiliary part consists of a frame, a turning rake, a first heating pipe, and a second heating pipe. The frame is fixed to the conveyor. The first heating pipe and the second heating pipe are fixed to the front and rear sides of the frame, respectively.

[0015] Furthermore, a control box is fixed to the top surface of the base, and a microprocessor and a 4G module are installed inside the control box.

[0016] This invention provides a pretreatment feeding system for solid waste incineration furnaces, which has the following beneficial effects: From the perspective of the initial stage of solid waste treatment, this application demonstrates that the linkage design of the crushing and shearing sections significantly improves pretreatment efficiency. The two crushing rollers inside the crushing chamber rotate synchronously in opposite directions under the drive of a motor and gear meshing, effectively crushing the input solid waste. Meanwhile, the two base plates of the shearing section reciprocate through the cooperation of guide rods and helical springs, and the shearing teeth on their inner sides pre-shear the solid waste before crushing. This dual "shearing + crushing" treatment mode reduces the impact load when large pieces of solid waste directly enter the crushing rollers, and also breaks down irregular large pieces of waste into smaller, more easily crushed pieces through shearing, significantly improving crushing efficiency and avoiding the jamming or incomplete crushing problems that may occur with a single crushing method. Simultaneously, the two inclined guide plates on the inner wall of the crushing chamber are mirror-distributed, precisely guiding the solid waste into the gap between the two crushing rollers, ensuring that every piece of material is fully crushed, further guaranteeing the uniformity of the crushing effect. In the screening stage after crushing, the vibration screening design of the screening component effectively improves the quality of solid waste grading. The screen base inside the screening box is connected to the bottom of the box through four spring rods. When the first motor drives the first rotating shaft and the drive block to rotate, the drive block and the semi-cylindrical protrusion on the screen base make continuous elastic contact, causing the screen to vibrate at high frequency. This vibration method can not only quickly separate solid waste of different particle sizes after crushing, ensuring that materials that meet the combustion requirements enter the next stage, but also avoid screen clogging through vibration, maintaining the continuity and stability of screening. Compared with traditional static screening or low-frequency vibration screening, this design has higher screening efficiency and can complete the grading of a large amount of material in a short time, providing uniform raw materials for subsequent processing. The mixing unit and blower in this application achieve uniform mixing and efficient transportation of solid waste while also meeting environmental protection requirements. The blower draws the screened solid waste from the screening box and transports it to the mixing tank, eliminating the cumbersome steps of manual handling or mechanical conveying and reducing material loss and pollution during transportation. The mixing teeth inside the mixing tank rotate at high speed under the drive of a second motor, which can fully mix solid wastes of different compositions and moisture levels, making the physical properties of the materials more consistent, which is conducive to complete combustion and heat release during subsequent combustion. In addition, the exhaust pipe connected to the mixing tank introduces the internal gas into a filter box filled with filter cotton, which can effectively adsorb odors and fine particulate matter in the gas, prevent harmful gases from leaking out directly, reduce pollution to the operating environment and surrounding air, and meet the requirements of environmental protection treatment. The combination of the conveyor and auxiliary components in this application further optimizes the drying process of solid waste and improves the combustion performance of the material. The stirred solid waste is discharged onto the conveyor. During forward transport, the heat generated by the first and second heating pipes heats and dries the material, removing excess moisture and preventing incomplete combustion or excessive smoke production due to high humidity. The turning rakes on the frame contact the conveyor belt, continuously turning the solid waste during transport, ensuring more even heating and thorough drying, thus solving the problem of localized incomplete drying caused by material accumulation in traditional drying processes. The dried solid waste has a lower moisture content, significantly improving combustion efficiency while reducing energy consumption and pollutant emissions during combustion. The intelligent design of the control box in this application greatly improves the ease of operation and automation of the system. The microprocessor connects to a mobile terminal via a 4G module, allowing operators to remotely send commands to achieve precise control of equipment such as the first motor, fan, second motor, conveyor, and heating pipes. This eliminates the need for on-site operation of each component, saving labor costs and reducing errors and safety risks associated with manual operation. This remote control method also facilitates real-time monitoring of the system's operating status, enabling timely detection and handling of equipment malfunctions, ensuring the stable operation of the entire pretreatment system, and improving overall processing efficiency. In summary, this pretreatment feeding system for solid waste incineration furnaces, through the organic integration of its components, achieves fully automated processing of solid waste from shearing, crushing, screening, mixing to drying. It not only significantly improves pretreatment efficiency and quality, ensuring the stability and efficiency of subsequent combustion processes, but also demonstrates excellent environmental performance and ease of operation, providing reliable technical support for the harmless, reduced-volume, and resource-based treatment of solid waste.

[0035] The working principle of this embodiment is as follows: Waste to be crushed is fed into the crushing box 202.

The microprocessor 901 starts the motor, and under the meshing transmission of two gears 204, the two crushing rollers 203 rotate synchronously in opposite directions, thus crushing the solid waste. Simultaneously, as the two crushing rollers 203 rotate, the two force blocks 305 and the two base plates 302 reciprocate. The two base plates 302 drive the shearing teeth 303 to reciprocate, thus shearing the solid waste. The crushed solid waste is then discharged into the screening box 401. The mobile terminal operated by a user sends instructions to the microprocessor 901 via the 4G module 902. The microprocessor 901 drives the first motor 408 to rotate. The first motor 408 drives the first rotating shaft 406 and the drive block 407 to rotate. Through the continuous elastic contact between the drive block 407 and the protrusion 405, energy is generated. The system generates vibration, which enables the screening of pulverized solid waste. After screening, the operator's mobile terminal sends instructions to the microprocessor 901 via the 4G module 902. The microprocessor 901 then starts the fan 5 to transport the screened solid waste into the mixing tank 602. The second motor 606 is then started, which drives the second rotating shaft 604 and the stirring teeth 605 to rotate, thus mixing the solid waste. The mixed solid waste is then discharged onto the conveyor 7 and transported forward. Simultaneously, the operator's mobile terminal sends instructions to the microprocessor 901 via the 4G module 902. The microprocessor 901 then connects the power supply to the first heating tube 803 and the second heating tube 804. The heat generated by the first heating tube 803 and the second heating tube 804 can dry the solid waste on the conveyor 7. At the same time, the turning rake 802 turns the solid waste over, which can better complete the drying of the solid waste on the conveyor 7.
