The gradient filtration design achieves the step-by-step interception of impurities from large to small. Combined with the bottom spiral conveyor discharge structure, it can completely and cleanly discharge the intercepted solid waste from the system, avoiding the accumulation of impurities in the equipment.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0023] Please see Figures 1-5 The present invention provides a technical solution: For an example, please refer to... Figure 1 , 2 3, 4 and 5, an automated solid waste sorting and separation system for waste oil, including a main storage section, a filter assembly, a chopping structure, a heating assembly, an oil extraction component, and a discharge structure. The main storage section includes a main shell 1 and a base 2. The main shell 1 is a cylindrical structure with an open top and a removable top cover 4 for easy internal cleaning and maintenance. The lower end of the main shell 1 has a downwardly extending lower protruding end 17 for accommodating the lower structure of the oil extraction component. The base 2 is installed below the main shell 1 and has a pull-out box 3 inside for receiving and temporarily storing solid waste discharged from the discharge structure.
[0024] The filter assembly is integrally connected to the top cover 4 and is installed inside the main body shell 1 together with the top cover 4. The filter assembly includes a filter screen cylinder 10, a filter screen layer 12 and a filter bottom cylinder 13 from top to bottom. The upper end of the filter screen cylinder 10 is fixed to the top cover 4, and the lower end is connected to the filter screen layer 12 and the filter bottom cylinder 13 through the docking end 14. The filter layer 12 is wrapped around the outside of the docking end 14 and connected to the filter bottom cylinder 13 to form a multi-layered filter structure. The filter cylinder 10, the filter layer 12 and the filter bottom cylinder 13 are all double-layer mesh structures, and their mesh diameters decrease sequentially, thereby achieving gradient filtration of solid impurities from coarse to fine. A heating element is provided in the inner interlayer of the filter assembly. In this embodiment, a heating resistance wire is used as the heating element. The heating resistance wire is evenly arranged between the double-layer mesh walls of the filter cylinder 10, the filter layer 12 and the filter bottom cylinder 13. It can heat the flowing grease after being energized. The viscosity of the heated grease is reduced and its fluidity is enhanced, making it easier to pass through the filter and separate from solid impurities, thereby improving filtration efficiency and grease yield.
[0025] Please refer to Figure 1 , 2 3, 4 and 5, the feeding structure is set in the middle of the top cover 4, including the inlet 5 fixedly connected to the top cover 4, and the inlet groove 8 is opened at the corresponding position of the top cover 4 so that the material can smoothly enter the filter assembly. Inside the inlet 5, a mounting plate is fixed by several connecting rods a7. The mounting plate is equipped with a drive motor a6. The output shaft of the drive motor a6 extends downward and connects to the chopping structure. The shredding structure includes a connecting shaft 9 connected to the output end of the drive motor a6. Multiple rotary blades 11 are fixed on the outside of the connecting shaft 9. Several slots 26 are opened on the rotary blades 11 to enhance the cutting and turbulence effect during rotation. Several inclined stirring rods are also fixed at the lower end of the connecting shaft 9. When the drive motor a6 is working, the rotary blades 11 rotate at high speed to shred the large volume of solid waste. At the same time, the stirring rods push the material downward and promote its mixing with hot oil, which is beneficial for subsequent separation.
[0026] The mixture, after being chopped and heated, flows downward under the influence of gravity, passing through the filter cylinder 10, the filter layer 12, and the filter bottom cylinder 13 in sequence. Solid impurities are trapped inside the filter screen at each stage, while molten or flowing grease passes through the mesh and enters the storage space inside the main body shell 1. The entire filter assembly is connected to the top cover 4, which is detachable and can be removed for cleaning when a certain amount of filter material accumulates.
[0027] The oil extraction component is used to extract the separated grease. It includes an oil suction pipe 15 and an oil suction cylinder 16. The upper end of the oil suction pipe 15 is connected to the oil outlet port located on the upper side of the main body shell 1, and the lower end is connected to the oil suction cylinder 16. The oil suction cylinder 16 extends to the bottom of the lower protruding end 17, which can extract the grease deposited at the bottom layer to the maximum extent. An external oil pump is connected to the oil suction pipe 15 through the oil outlet port to realize the continuous or intermittent extraction of grease.
[0028] After solid impurities trapped in the filter assembly accumulate to a certain extent, they need to be discharged from the system. The discharge structure is installed at the bottom of the main body shell 1 and extends into the installation space of the base 2. The discharge structure includes a fixed plate that is fixed to the main body shell 1 by several connecting columns 23. An upwardly extending protrusion is provided above the fixed plate. A conveying cylinder 18 is connected to the protrusion. The upper opening of the conveying cylinder 18 is connected to the lower end of the filter bottom cylinder 13 to receive solid waste falling from the filter assembly.
[0029] A discharge trough is provided in the middle of the protrusion. The lower end of the discharge trough is connected to the inner and outer sides of the connecting cylinders a21 and b22 respectively. The interior of the discharge trough is reinforced by several connecting rods b25. A drive motor b20 is installed on the lower surface of the fixed plate. Its output shaft passes through the protrusion and extends into the inside of the conveying cylinder 18. A screw conveyor 19 is fixed at the shaft end. When the drive motor b20 is started, the screw conveyor 19 rotates and pushes the solid waste falling into the conveying cylinder 18 downwards. The waste falls through the discharge trough into the channel between the connecting cylinders a21 and b22 and finally falls into the pull-out box 3.
[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
