[0002] Biodiesel refers to fatty acid methyl esters or ethyl esters formed by esterification of vegetable oils (such as rapeseed oil, soybean oil, peanut oil, corn oil, cottonseed oil, etc.), animal oils (such as fish oil, lard, tallow, mutton oil, etc.), waste oils or microbial oils with methanol or ethanol. Biodiesel is a typical "green energy" with good environmental performance, good engine starting performance, good fuel performance, wide source of raw materials, and renewable characteristics. However, in real life, we find that when using waste cooking oil to process biodiesel, the waste cooking oil contains a large amount of wastewater and waste residue, mainly vegetable leaves and bones.

At the same time, it will rotate around the outer side of the first bevel gear 94 arranged at the bottom of the fixing frame 93, so that the brush 6 arranged on the outer side of the driving rod 103 can also rotate with the first bevel gear 94 as the axis while rotating, so as to achieve the effect of comprehensively cleaning the surface of the filter screen 4. When the impurities on the filter screen 4 are discharged through the discharging end of the screening machine body 2, they will fall on the receiving plate 112 arranged at one end of the conveyor belt 3. Since the surface of the receiving plate 112 is sloped, the impurities falling on the receiving plate 112 will slide along its surface to the conveyor belt 3, and the auxiliary plates 111 arranged on both sides of the conveyor belt 3 can prevent a large amount of oil impurities from falling on the ground and causing environmental pollution. When the oil impurities fall on the rotating conveyor belt 3, the power motor 12 1 will control the first gear 122 to rotate. When the first gear 122 rotates, the second gear 124 meshing therewith will rotate together with the first gear 122. When the second gear 124 rotates, the roller 123 arranged in the second gear 124 will rotate under the action of the second gear 124, so that when the oil impurities pass under the roller 123, the rotating roller 123 will flatten the surface of the oil impurities. When the roller 123 rotates under the action of the second gear 124, the transmission gear 131 arranged at one end thereof will rotate together with the roller 123 under the action of the roller 123, and the transmission belt 133 arranged outside the transmission gear 131 will rotate through multiple The latching tooth 134 drives the transmission gear 2 132 arranged at one end of the cone cylinder 5 to rotate synchronously.
