[0031] like Figures 1-5As shown, an oil inlet pipe 101 is fixedly connected inside the oil storage tank 1. The oil inlet pipe 101 penetrates the outer wall of the oil storage tank 1. A coarse filter element 102 is fixedly connected inside the oil inlet pipe 101. The coarse filter element 102 is located away from the oil storage tank 1.
[0032] like Figures 1-5 As shown, a filter plate seat 103 is fixedly connected to the inner wall of the oil storage tank 1. The filter plate seat 103 is located near the outer shell 4, and a filter plate 104 is fixedly connected inside the filter plate seat 103.
[0033] like Figures 1-5 As shown, a connecting rod 105 is fixedly connected to the inner wall of the oil storage tank 1. The connecting rod 105 is located near the top of the oil storage tank 1 and is fixedly connected to the inside of the filter plate 104. The connecting rod 105 passes through the filter plate 104.
[0034] like Figures 1-5 As shown, a conical guide block 106 is fixedly connected to the bottom of the connecting rod 105. The conical guide block 106 is located inside the oil storage tank 1 and is fixedly connected to the bottom of the filter plate 104.
[0035] like Figures 1-5 As shown, an oil outlet pipe 201 is fixedly connected to the outer wall of the sedimentation tank 2. The oil outlet pipe 201 is located near the bottom of the sedimentation tank 2. A water outlet pipe 202 is fixedly connected inside the sedimentation tank 2. The water outlet pipe 202 passes through the outer wall of the sedimentation tank 2 and is located at the bottom of the sedimentation tank 2. A control valve 203 is movably connected inside the water outlet pipe 202.
[0036] like Figures 1-5 As shown, a stepped baffle 204 and an inclined diversion plate 205 are fixedly connected to the inner wall of the oil storage tank 1. The stepped baffle 204 is located near the outer shell 4, and the inclined diversion plate 205 is located near the oil outlet pipe 201. An inlet 206 is opened at the center of the inclined diversion plate 205.
[0037] The operating method and working principle of this device are as follows: When the equipment cleans duck oil, the pressed duck oil is fed into the oil storage tank 1 through the oil inlet pipe 101. Before entering the oil storage tank 1, the duck oil first passes through the coarse filter element 102 for preliminary filtration to remove large particulate impurities. Because the coarse filter element 102 adopts a metal mesh design, it can increase the filtration area and avoid local impurity accumulation and blockage. Furthermore, the coarse filter element 102 is located far away from the oil storage tank 1, which makes the oil flow flushing effect stronger, helping to carry away impurities on the surface of the coarse filter element 102 with the fluid, further reducing blockage. Subsequently, the duck oil passes through the filter plate seat 103 and is further finely filtered by the filter plate 104 to remove smaller impurities. The filtered duck oil flows under gravity to the conical guide block 106. Due to its high viscosity, the duck oil flows slowly along its surface and gradually converges to the stepped baffle 204. Simultaneously, the heating wire 5 inside the outer casing 4 is activated by an external power source to continuously heat the oil storage tank 1, maintaining a high-temperature environment to remove odors and some moisture from the duck oil, thus achieving purification. At this point, residual moisture remains in the duck oil, requiring oil-water separation. During oil-water separation, duck oil continues to flow along the stepped baffle 204 and reaches the surface of the inclined guide plate 205. Through the buffering effect of the inclined guide plate 205, the duck oil gradually flows into the inlet 206 and then slowly into the sedimentation tank 2, effectively reducing disturbance to the settled duck oil in the sedimentation tank 2 during the inflow process. In the sedimentation tank 2, the duck oil settles and, after the oil-water separation is complete, because the density of oil is less than that of water, the duck oil naturally floats on the surface, while excess water gradually settles to the outlet pipe 202 under gravity. As a result, the duck oil after heat treatment... The water content is relatively low, and the water can completely accumulate in the outlet pipe 202. At this time, the purified duck oil in the upper layer can be extracted through the oil outlet pipe 201. After the oil is discharged, the control valve 203 is opened to discharge the excess water in the lower layer, thus achieving the final treatment of oil-water separation. The connecting rod 105 supports the conical diversion block 106 to prevent it from shaking during the diversion of duck oil, which would affect the diversion effect. At the same time, the support leg 3 supports the entire equipment and improves the overall stability of the oil storage tank 1. The heating wire 5 is a technology that is already available on the market and will not be described in detail here.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
