Description

Technical Field

[0001] The present invention relates to the technical field of medical waste treatment, in particular to a medical waste harmless treatment device. Background Art

[0002] Medical waste, due to its harmful properties such as carrying pathogenic microorganisms and chemical pollutants, can easily cause serious environmental pollution and public health problems if not handled properly. Current mainstream medical waste treatment methods include incineration, chemical disinfection, and high-temperature sterilization, but all have significant shortcomings.

[0003] While chemical disinfection can effectively inactivate pathogens, it cannot completely render waste harmless. Residues still require further disposal, and the chemicals themselves can cause secondary environmental pollution. While high-temperature sterilization can kill microorganisms, its effectiveness in reducing waste is limited, and treated waste still needs to be landfilled or incinerated, increasing subsequent disposal costs.

[0004] Incineration, currently the most thorough method for medical waste treatment, can achieve waste reduction and harmlessness. However, traditional incineration equipment still faces numerous challenges in practical applications: first, incomplete combustion leads to excessive harmful gas emissions; second, low thermal energy utilization results in energy waste; and third, the lack of an effective flue gas treatment system makes it difficult to meet increasingly stringent environmental protection requirements.

[0005] Existing technologies, such as the medical waste treatment device disclosed in Chinese Patent CN112893398A, improve treatment efficiency by combining chemical disinfection with mechanical pulverization. However, these devices still suffer from significant drawbacks: limited treatment scope, applicable only to specific types of medical waste; inability to achieve complete mineralization of the waste; and a lack of effective purification measures for incineration flue gases. These issues severely restrict the effectiveness and environmental performance of medical waste treatment.

[0006] Therefore, there is an urgent need to develop a medical waste harmless treatment equipment that can achieve efficient crushing, full combustion, and flue gas purification to address the shortcomings of existing technologies and meet the high efficiency, environmental protection, and economic requirements of modern medical waste treatment.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] (1) Efficient synergistic crushing and recycling: Through the linkage design of the crushing tooth roller, the screening trough seat and the rocker element, the initial crushing and screening of the waste is achieved. The large particles of waste that do not meet the standards are automatically returned to the conveyor drum through the pusher rack and re-entered into the crushing box by the spiral push roller for secondary crushing. This closed-loop processing mechanism significantly improves the efficiency of waste refinement and ensures the uniformity and thoroughness of the subsequent incineration step.

[0022] Specifically, by adding the waste material to be crushed at the opening outside the first conveyor cylinder, the first spiral push roller will feed the waste material into the crushing box through the feeding hopper, and the waste material will be crushed by the mutually meshing and rotating crushing tooth rollers. At this time, the crushed waste material will fall into the screening trough seat below. At this time, the second motor drives one of the first connecting rods, causing the second connecting rod, the third connecting rod and the fourth connecting rod to perform eccentric movement, controlling the pusher to realize the downward right movement and upward left movement in a cycle, and the large particles of waste material that cannot be screened inside the screening trough seat are discharged back into the first conveyor cylinder through the discharge trough box, achieving the effect of cyclic crushing and feeding until the waste material is completely refined. The coordinated movement of the screen layer and the rocker member avoids the problem of easy clogging of traditional static screening, and the design of the cleaning plate reduces the need for manual intervention.

[0023] (2) Dynamic incineration and flue gas circulation purification: The incinerator rotates at a constant speed through the meshing of the transmission ring and the gear, allowing the waste to fully tumble in the high-temperature flame. At the same time, the flue gas pipe and ventilation pipe work together to mix the incompletely burned flue gas with oxygen and then re-introduce it into the incineration chamber. This design not only enhances combustion efficiency, but also significantly reduces the emission of harmful gases through circulation purification, improving environmental performance.

[0024] Specifically, the refined crushed materials are discharged into the conveying track below through the discharge port at the bottom of the crushing box, and then sent to the second conveying cylinder via the conveyor belt, and then sent to the incineration chamber by the second spiral push roller to ensure uniform incineration of small-size crushed materials. At this time, the drive gear is driven to rotate with the drive gear ring of the incineration cylinder, and the incineration cylinder is guaranteed to rotate and roll at a uniform speed to ensure that the internal waste is fully in contact with the high-temperature flame. At the same time, the incompletely burned flue gas is led out by the flue pipe, and after being connected to the ventilation pipe, it is entrained by the oxygen introduced and re-enters the incineration chamber, effectively ensuring the purification effect of the combustion products. Through the hybrid design of the flue pipe and the ventilation pipe, the incompletely burned flue gas and oxygen are reintroduced into the incineration chamber. Combined with the dynamic oxygen supply of the blower, the emission of harmful gases (such as CO and dioxins) can be reduced to below the environmental protection standard.

[0025] (3) Intelligent monitoring and optimization: The smoke concentration sensor monitors the smoke data of the exhaust pipe in real time, and dynamically adjusts the rotation speed of the incinerator and the oxygen supply to form a feedback optimization mechanism. This intelligent control ensures the stability and efficiency of the incineration process and further guarantees the harmless treatment effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Through the above technical solution, the screen layer of the screening trough seat 301 can be used for screening, and then the cleaning plate at the bottom of the pushing rack 304 will re-discharge the crushed materials that cannot be screened into the first conveying cylinder 306 through the discharge chute box 305, and then be loaded and crushed again.

[0044] In this embodiment, a third motor 10 is fixedly installed at the bottom of the first conveying cylinder 306, and the output end of the third motor 10 is fixedly connected to the bottom end of the first spiral push roller 307.

The bottom of the crushing box 1 is a discharge port, and a conveying track 11 is fixedly connected to the bottom of the discharge port. The inner side of the conveying track 11 is connected to a conveyor belt 12 for transmission.

[0045] The crushed waste can then be discharged into the conveying track 11 below through the discharge port, and discharged into the feeding chamber 201 through the conveyor belt 12 inside the conveying track 11, and then sent into the cylinder for incineration treatment through the second conveying cylinder 401 through the front side of the incineration cylinder 404.

[0048] Thus, the valve table pipeline on the gas box 15 can be connected to the flamethrower 14 to start the power supply of the flamethrower 14.

[0053] An exhaust pipe 18 equipped with a valve is fixedly installed on the rear side of the positioning platform 403, and a smoke concentration detection sensor 19 is fixedly installed on the outside of the exhaust pipe 18. The detection probe of the smoke concentration detection sensor 19 extends to the inside of the exhaust pipe 18, and the exhaust pipe 18 is connected to a dust recovery device.

[0054] Specifically, the smoke concentration detection sensor 19 is used to detect the smoke concentration of the exhaust pipe 18 to obtain detection data on whether the combustion is sufficient, which is convenient for further adjustment and optimization of the ventilation volume and the turning speed to improve the combustion efficiency of the internal waste.

[0055] The working principle of the medical waste harmless treatment equipment:

[0056] Medical waste is added through the external opening of the first conveying cylinder 306. At this time, the third motor 10 drives the first spiral push roller 307 to loosen the waste and send it into the crushing box 1. The first motor 7 drives the crushing tooth rollers 6 to engage and rotate with each other to crush the waste. The crushed waste falls into the screening trough 301 below and is screened with small particles through the screen layer. The second motor 9 drives the first connecting rod 3031, and thereby drives the second connecting rod 3032, the third connecting rod 3033 and the fourth connecting rod 3034 to perform eccentric movement, controlling the pusher frame 304 to realize a cyclic movement of descending to the right and lifting to the left, and the large particles of waste that cannot be screened are re-discharged into the first conveying cylinder 306 through the discharge trough box 305 to ensure repeated crushing effect until the waste is completely refined.

[0057] The refined crushed materials are discharged into the conveying track 11 through the discharge port at the bottom of the crushing box 1, and are sent to the second conveying cylinder 401 of the incineration chamber 202 via the conveyor belt 12. The second spiral push roller 402 is driven by the fourth motor 13, and the second spiral push roller 402 is used to send the waste into the incineration chamber 202. At this time, the fifth motor 17 drives the transmission gear 4062, and the transmission gear 4062 drives the transmission gear ring 4061 engaged with the incineration cylinder 404 to rotate, so that the incineration cylinder 404 rotates and rolls at a uniform speed to ensure that the small-particle crushed materials are fully in contact with the high-temperature flame, thereby ensuring a uniform incineration effect.

[0058] The unburned flue gas is drawn out through the flue pipe 4051 and then passed into the ventilation pipe 4052. At this time, the blower 16 continuously introduces air through the ventilation pipe 4052, so that oxygen and smoke are mixed in large quantities, and then the flue gas is carried back into the combustion chamber 202, where it is fully in contact with the high-temperature flame and burned, thereby effectively ensuring the purification effect of the combustion products.

[0059] The exhaust pipe 18 is used to collect the waste gas generated by combustion. At the same time, the smoke concentration detection sensor 19 emits a high-energy microwave particle field through the detection probe based on the Doppler effect. When the smoke flows through the inside of the pipe, the smoke particles will contact the microwave particles and reflect them back to the inside of the detection probe for reception. A voltage change signal is generated in the control circuit inside the detection probe. After analog conversion of the voltage change signal, it is converted into microwave frequency and amplitude change data through the sensor control module, and then the concentration data of the smoke particles is calculated. According to the smoke concentration threshold, it is determined whether the current combustion is sufficient, and then the air intake and the flip speed of the incinerator 404 are optimized and adjusted.
