Description
Technical Field
[0001] The utility model belongs to the technical field of acidified oil derivation equipment, and in particular relates to a residue pressing device for preparing acidified oil from waste grease. Background Art
[0002] With the acceleration of industrialization and the improvement of people's living standards, global energy consumption continues to increase, resulting in a large amount of waste and pollutant emissions. In this case, the environmental protection industry has emerged, and various new technologies have been continuously developed and applied. Acidification oil technology is one of them. Through chemical reactions, waste grease and waste animal and plant oils are acidified to produce different chemicals, which can be used to produce biodiesel, etc., while achieving resource recycling and reducing pollutant emissions.
[0003] Acidified oil residue is a waste product during the production of acidified oil. In order to recycle it, it is generally necessary to further press the oil residue. In the existing acidified oil residue press, filter cloth needs to be covered on the outside of the oil residue during the oil pressing process to achieve effective filtration of the residue. However, this practice is not only cumbersome to operate, but also the structure of the oil press cylinder also has room for optimization. The oil press cylinder is currently composed of a plurality of vertical bars and a plurality of hoops welded together, and the hydraulic press at the top applies pressure to the oil residue through a pressing plate. In this process, the grease can flow out from the gaps between the vertical bars and the hoops. However, due to the large number and small gaps, the gaps between these hoops and the vertical bars are prone to accumulate dirt, which brings inconvenience to the subsequent cleaning work. In addition, the service life of the filter cloth is limited under a high-intensity pressing environment, which also increases the cost of consumables. Therefore, the utility model proposes a residue pressing device for acidified oil from waste grease, which has the advantages of avoiding the accumulation of dirt, facilitating disassembly and cleaning, and reducing the cost of consumables.
[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example
[0017] See also Figure 1-2 The utility model provides the following technical solutions: A residue squeezing device for making acidified oil from waste oil, comprising an oil cylinder 1, an outer wall structure, a filter cylinder 5, a fixed frame 6, and a hydraulic press 7. The oil cylinder 1 is a core component, and its outer wall is provided with a flange 2 and a concave edge 3. These two structures are evenly distributed on the outer wall of the oil cylinder 1 and are arranged in an alternating manner, so that the squeezed oil can be discharged along the flange 2. The side wall of the concave edge 3 and the bottom wall of the oil cylinder 1 are evenly provided with oil outlets 4 to ensure that the oil can be discharged smoothly. A filter cylinder 5 is installed inside the oil cylinder 1, and the outer wall of the filter cylinder 5 is tightly fitted to the inner wall of the oil cylinder 1, which plays an effective filtering role and prevents residues from entering the subsequent processing flow. A fixed frame 6 is arranged on the outside of the oil cylinder 1 to support and fix the entire device to ensure its stability during operation. A hydraulic press 7 is installed on the top of the fixed frame 6. The hydraulic press 7 is firmly fixed to the top of the fixed frame 6. Its output end passes through the center of the fixed frame 6. A pressing plate 8 is fixed at the end of the output end, so that the hydraulic press 7 can accurately apply pressure and effectively squeeze the waste oil residue through the pressing plate 8. An oil pan 9 is set at the bottom of the fixed frame 6, just below the oil cylinder 1, for collecting the oil generated during the squeezing process. An oil guide port 10 is set on one side of the oil pan 9 to facilitate the extraction of the collected oil for subsequent processing.
[0018] In order to conveniently and quickly collect the grease into the oil pan 9 , in this embodiment, as a preferred technical solution of the utility model, the top end surface of the flange 2 is inclined, and the lowest point of the inclination is consistent with the direction of the oil guide port 10 of the oil pan 9 .
[0019] In order to facilitate the later cleaning of the oil pan 9, in this embodiment, as a preferred technical solution of the utility model, the oil pan 9 and the fixed frame 6 are detachable structures.
[0020] In order to fix the filter cartridge 5 , in this embodiment, as a preferred technical solution of the utility model, a top cover 11 is provided on the top of the oil cartridge 1 , and a pressing port 12 is provided at the center of the top cover 11 .
[0021] In order to facilitate the disassembly and assembly of the top cover 11 , in this embodiment, as a preferred technical solution of the utility model, the top cover 11 and the oil cylinder 1 are fastened together by bolts, and the filter cartridge 5 is pressed and fixed inside the oil cylinder 1 by the top cover 11 .
[0022] In summary, with the aid of the above-mentioned technical scheme of the utility model, when in use, the oil residue is placed in the filter cartridge 5, and then the output of the hydraulic press 7 is used to drive the pressure plate to descend through the pressing port 12 at the center of the top cover 11 to enter the inside of the filter cartridge 5 to forcefully squeeze the oil residue. The grease in the oil residue is squeezed out from the bottom wall of the oil cartridge 1 and the oil outlet 4 of the concave edge 3 through the filter holes on the surface of the filter cartridge 5. The grease squeezed out from the oil outlet 4 of the concave edge 3 of the oil cartridge 1 flows along the inclined top end face of the flange 2 to the lowest point and falls to the oil guide port 10 of the oil pan 9. The grease squeezed out from the oil outlet 4 of the bottom wall of the oil cartridge 1 can directly fall into the oil pan 9 and be uniformly discharged directly from the oil guide port 10 for collection. When cleaning, the bolts of the top cover 11 can be removed and the top cover 11 can be removed, and then the internal filter cartridge 5 can be pulled out from the inside, and the oil cartridge 1 and the filter cartridge 5 can be rinsed with a high-pressure water gun respectively.
