Description

Technical Field

[0001] This utility model relates to the technical field of waste oil treatment equipment, and in particular to a spiral electric heating composite anti-clogging conveyor. Background Technology

[0002] Waste oil is a mixture of waste oil generated in food processing and industrial production, containing animal, vegetable, and mineral oil components. Its indiscriminate discharge will pollute the water and soil environment, block municipal pipelines, and directly threaten ecological health. In response to the problems of low transmission efficiency and high energy consumption of traditional waste oil treatment equipment, the spiral electric heating composite conveyor has emerged. This equipment adopts a spiral propulsion structure combined with an electric heating system. Through the composite design, it realizes continuous and uniform material transportation, effectively improves oil processing efficiency, reduces energy consumption, and provides a reliable guarantee for resource utilization.

[0003] A search revealed Chinese Patent Publication No. CN210064544U, which discloses a conveying device for oil processing, including an oil storage tank and a conveying cylinder. The lower side of the oil storage tank is connected to three or more evenly distributed vertical plates, the lower ends of which are connected to each other via a base plate. A third sleeve plate is provided on the outer side of the oil storage tank. The end of the conveying cylinder furthest from the oil storage tank is open. A spiral conveying assembly is provided inside the conveying cylinder. The angle adjustment mechanism includes an electric telescopic rod, one end of which is hinged to a second sleeve plate via a first hinge seat. The telescopic rod extends and retracts, pushing the connected conveying cylinder to rotate a certain angle around the axis of the rotating shaft, thus facilitating the adjustment of the discharge height and angle of the oil in the conveying cylinder as needed. The pipe connection assembly realizes the oil transfer between the oil storage tank and the conveying cylinder, and the spiral conveying assembly further facilitates the transfer of oil, making it convenient to use. However, in actual use, the above device suffers from oil solidification and clogging problems. Therefore, a spiral electrically heated composite anti-clogging conveyor is proposed to solve these problems. Utility Model Content

[0046] Working principle: First, the first motor 4 drives the rotating shaft 5 to rotate. When waste oil containing particulate impurities enters the barrel 3, the material passes through the coarse filter plate 8 and the fine filter plate 9 in the barrel 3 for double filtration. The two filtration structures intercept physical impurities of different particle sizes, ensuring that the particles are effectively blocked at the front end of the spiral electric heating system. At the same time, the scraper 7 connected to the rotating shaft 5 continuously removes impurities attached to the surface of the filter plates, avoiding filter hole blockage and maintaining filtration efficiency and continuous operation of the device. This structure reduces the interference of foreign objects on the spiral device and electric heating wire 205 in the heating process by pre-separating impurities, improves heat transfer efficiency and reduces the risk of local overheating, while ensuring the smooth flow of material conveying channels and significantly reducing the probability of mechanical jamming or blockage caused by impurity retention. Ultimately, it achieves high efficiency and stability in the conveying process and extends the service life of the core components of the equipment.

[0047] Furthermore, when the heating wire 205 is in a high-temperature state due to continuous operation, the system activates the air-cooling device 202 configured on the top of the cover 201, and in conjunction with the cooling drawer 203, releases the low-temperature airflow generated by the sublimation of dry ice. The cold air is evenly transferred to the surface of the heating wire 205 through the high thermal conductivity interface of the graphene plate 204, achieving targeted heat dissipation. This process efficiently removes local heat through the rapid thermal conduction characteristics of the graphene plate 204. The active heat dissipation of the air-cooling device 202 and the auxiliary cooling of the cooling drawer 203 work together to effectively suppress the continuous rise in temperature of the heating wire 205, preventing material embrittlement or abnormal resistivity due to the accumulation of thermal stress. The graphene plate 204, as a heat exchange medium, not only ensures the heat transfer efficiency between the cold air and the heating wire 205, but also buffers the physical impact of sudden temperature changes on the heating wire 205. This temperature control mechanism significantly slows down the oxidation and aging process of the heating wire 205 by dynamically balancing its operating temperature, ensuring the long-term stable operation of the heating system.
