[0002] Waste cooking oil (Waste oil) is a recyclable resource. Through chemical and physical transformation and refining, it can be transformed into valuable resources, generating substantial economic and social benefits. Producing biodiesel from waste cooking oil is a major avenue for its resource utilization. Using waste cooking oil as a raw material for biodiesel production is not only inexpensive and readily available, but also highly beneficial for the comprehensive management of waste cooking oil, resulting in substantial economic benefits.

[0003] Currently, the main process for treating waste cooking oil in urban kitchen waste treatment plants involves heating the waste cooking oil, performing solid-liquid separation, and then subjecting the separated liquid phase to three-phase centrifugation to separate the waste cooking oil into crude oil, solid residue, and wastewater. Existing treatment systems often suffer from low impurity removal rates, low oil content after purification, and the long period of natural sedimentation required to achieve a high oil content in the downstream oil storage tanks. Consequently, the storage tanks are very large, have a low degree of automation, and face harsh on-site environments.

[0004] Therefore, it is necessary to propose a fully automated transfer and processing system for waste cooking oil to improve the oil content of waste cooking oil after purification, realize automated operation, and realize the automated transportation and transfer of oil. Utility Model Content

[0027] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention.

[0028] See also Figure 1 , and combined with Figure 2 and Figure 4 As shown, the utility model is a fully automated transfer and processing system for waste cooking oil, including a grease preprocessor 1 and a processing tank 2. The top of the grease preprocessor 1 is provided with an oil outlet 11, and a processing chamber 21 is provided in the processing tank 2. The top of the processing chamber 21 is provided with an oil outlet 22, and the lower part of the processing chamber 21 is provided with an inlet hole 23 connected with the oil outlet 11 through an oil pump 3. The lower part of the processing chamber 21 is conical, and a guide outlet 24 is provided at the bottom of the processing chamber 21. A plurality of separation discs 4 are provided on the upper part of the processing chamber 21. The separation discs 4 are polygonal cone structures, and the top of each separation disc 4 is provided with an outlet 41, and the top outlets of adjacent separation discs 4 are staggered in the vertical direction.

[0029] During use, the pretreated waste oil (i.e., the oil-water mixture from which solid impurities have been filtered) is introduced into the grease preprocessor 1 and is heated by the grease preprocessor 1. After the heated oil-water mixture is heated, the grease melts and floats on the water surface to form a grease layer. The liquid water is located at the lower part because of its higher density than the oil. The upper grease layer is extracted by the oil pump 3 through the outlet 24 and introduced into the treatment tank 2. Since the outlet 24 is at the bottom of the treatment tank 2, the waste water containing waste water will automatically move upward after entering the treatment tank 2. During the movement, since the outlets of the separation discs 4 are staggered, when the waste grease water is introduced, it will first touch the inner side of the separation disc 4, so that the grease will not rise directly vertically, but will rise in a zigzag shape along the outlet 41 of the separation disc 4 and hit the inner side of the separation disc 4, thereby separating the sludge or impurities trapped in the oil from the oil to improve the purity of the grease separation. For the specific structure, please refer to Figure 5 shown.

[0030] In order to prevent the oil from condensing and solidifying in the delivery pipe during the extraction and delivery process of the oil pump 3, and covering some particles, thereby affecting the subsequent purification effect, the utility model also provides a heater 6 on the delivery pipe of the oil pump 3, or embeds a heating resistance wire in the delivery pipe, so that the waste oil continues to be heated during the delivery process to ensure that the waste oil introduced into the processing tank 2 is in a liquid state, thereby ensuring its separation effect.

[0031] It should be noted that a plurality of partitions 5 are provided in the processing tank 2 of the present invention, which divide the processing chamber 21 into a plurality of cavities 51, and a baffle 52 is provided on one side of the partition 5. The partition 5 and the baffle 52 are spaced apart to form a reflux channel 53, and an inlet hole 23 communicating with the adjacent side cavity 51 is provided at the bottom of the baffle 52, and the separation disc 4 is respectively installed in each cavity 51.

[0032] With such arrangement, when the waste grease enters the first cavity 51 through the inlet hole 23, the waste grease floats due to its own density and acts on the side end surface of the separation disc 4. After being subjected to the force on the separation disc 4, it will be decelerated, and the grease will be intercepted to obtain sludge or impurities separated from the grease. In this way, the grease on the stacked separation discs 4, after multiple actions, enters the top outlet on the top separation disc 4 and is discharged, thereby realizing the purification of the waste grease. The grease after one purification overflows from the top of the partition 5, enters the reflux channel 53, and is then introduced into the second cavity 51 through the inlet hole 23. This cycle is repeated, and after multiple purification actions, the rapid purification of the waste grease can be completed, so that multiple separation and purification can be formed through multiple different cavities 51 to ensure its purification effect.

[0033] It should be noted that the cross-section of the separation disc 4 of the present invention is quadrilateral, and the separation disc 4 is in the shape of a shell, the cross-sectional opening area of ​​the bottom thereof is larger than the cross-sectional opening area of ​​the top thereof, that is, the separation disc 4 is a polygonal prism-shaped shell, and the area of ​​the side edges of the separation disc 4 is not equal, so that the top outlets 41 of adjacent separation discs 4 are staggered in the vertical direction. When the grease is introduced, it will collide with the separation disc 4 multiple times, reducing the flow rate. At the same time, through the collision, the volume of the grease molecules is reduced, and the particles coated therein are separated from them to ensure its purification effect.

[0034] It is worth noting that the inlet hole 23 of the present invention is equipped with an inlet pipe 55, and the output end of the inlet pipe 55 is tangentially arranged with the inner edge of the processing chamber 21 to form a vortex. By utilizing its centrifugal force, the solid particles in the waste grease can be introduced into the outlet 24 to realize the diversion output of the solid particles. For the specific structure, please refer to Figure 3 shown.

[0035] The processing tank 2 of the present invention is provided with a guide plate 56, which is installed at the lower part of the inlet hole 23 and at the upper part of the conical processing chamber 21, and the end of the guide plate 56 extends to the top of the guide outlet 24. The guide plate 56 can prevent waste oil from being directly input into the guide outlet 24, thereby affecting the oil separation effect.

[0036] The utility model discloses a fully automated waste cooking oil transfer and processing system. After pre-processing, the collected waste cooking oil is put into a grease pre-processor 1. The top floating oil is transferred to a processing chamber 21 by the grease pre-processor 1. The oil and water are purified twice by separation discs 4 inside the processing chamber 21. Specifically, the separation discs 4 are staggered. When the floating oil moves upward, it can interact with the inner edge surface of the separation discs 4. In this way, impurities in the floating oil can be reduced and the purity of the oil can be improved.

[0037] Finally, the method of this application is only a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this utility model should be included in the scope of protection of this utility model.
