Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, the embodiment of the present invention provides a circulating filtration type oil-residue separation device, which can be used for separating an oil-residue mixture extracted at a high temperature by an oil-residue extraction device in a previous process of high-temperature treatment of dead animals. Specifically, the device is provided with a multi-stage filtration separation tank 1, the drawing of the embodiment is shown in two stages, which does not represent that only two stages are provided, and the stage number should be selected according to the actual separation effect, the field size and the like. Wherein, filtering separation groove 1 links to each other in proper order, and adjacent curb plate is filter 2, sets up a plurality of filtration pores 3 on the filter 2. Meanwhile, the interior of the filtering separation tank 1 is provided with a material guide plate 4 inclined towards one side of the filtering separation tank, and the inclination angle of the material guide plate is inconsistent with the multistage arrangement direction of the filtering separation tank 1. The lower part of the material guide plate 4 is provided with a slag outlet 5, the lower part of the slag outlet 5 is provided with an auger device, the auger device is also obliquely arranged, the first end at the lower part is closed, and the second end at the higher part is provided with a slag discharge hole 6.
The oil residue separation process comprises the following steps: the oil residue mixture is fed into a first-stage filtering and separating tank 1 from the oil high-temperature extraction process. Due to the arrangement of the filter plate 2, oil and fine slag pass through the filter plate 2 and enter the second-stage filtering and separating tank 1 from the first-stage filtering and separating tank 1. And the large slag in the first-stage filtering separation tank 1 flows to the lower side of the guide plate 4 under the action of the inclined guide plate 4 in the downward precipitation process, finally passes through the slag outlet 5 and falls into the auger equipment. The main purpose of the material guide plate 4 is to enable the large slag to flow and accumulate along with the material guide plate 4 to one side in the downward precipitation process and flow out from the slag outlet 5, so as to form more thorough separation with the oil liquid. The auger equipment is also obliquely arranged and continuously conveys the slag to the second end arranged at a high position, the slag is pushed to the second end by the action of the auger blade and is discharged from the slag discharge port 6, and the oil liquid flows to the first end of the auger equipment under the action of gravity and is temporarily stored. Therefore, the oil residue is separated by the combined action of the filtering separation tank 1 and the auger equipment.
The oil liquid filtered from the previous filtering and separating tank 1 to the next stage still contains a certain amount of slag materials and needs to be further separated, so that the multistage filtering and separating tank 1 is arranged in the embodiment, the oil-slag mixture filtered to the next filtering and separating tank 1 is continuously separated in the tank, the oil liquid with less slag content enters the next filtering and separating tank 1, and the slag materials enter the auger equipment for further separation from the slag material outlet 5 under the action of the guide plate 4. Through the arrangement of the multistage filtering separation tank 1, the residue content of oil liquid in the subsequent filtering separation tank 1 is further reduced, and the oil residue separation degree is improved. And the arrangement of the material guide plate 4 can ensure that the large slag which can not be filtered can move along the material guide plate 4, thereby reducing the possibility of blocking the filter holes 3 and ensuring the continuous and reliable use of the device.
Based on the analysis, the aperture of the filtering hole 3 is gradually decreased from the first stage to the back in this embodiment, so that the front filtering and separating tank 1 separates massive slag from oil, the back filtering and separating tank 1 separates small slag from oil, and the slag content in the oil finally separated is low, thereby achieving the required separation degree.
Because slag in the later filtering and separating tank 1 is smaller and slides at a slower speed along the guide plate 4 when being positioned in the filtering and separating tank 1, and is easy to stay near the filtering holes 3 to increase the possibility of blockage, the setting height of the filtering and separating tank 1 is gradually decreased from the first stage to the back in this embodiment, so that the slag filtered from the previous filtering and separating tank 1 and entering the next filtering and separating tank 1 has relative gravitational potential energy, and the slag can move smoothly along the guide plate 4 to the slag outlet 5, thereby reducing the possibility of staying around the filtering holes 3. In addition, the filtering holes 3 are arranged on the upper layer of the guide plate 4, so that the filtering holes 3 are ensured not to be blocked by slag accumulated on the lower layer.
In this embodiment, the outside of last level filter 2 sets up fluid collecting vat 7, and the below of slag charge discharge gate 6 sets up slag charge collecting vat 8, and fluid and slag charge are retrieved respectively and are made further processing or utilize. Meanwhile, the auger device in the embodiment comprises a first auger 9 and a second auger 10 which are obliquely arranged, wherein the first auger 9 is arranged below the slag charge outlet 5, the first end of the first auger is closed, the second end of the first auger is arranged above the second auger 10, and the first auger 9 receives the oil-slag mixture flowing out of the slag charge outlet 5 and spirally conveys the oil-slag mixture to the second end at a high position. Because the inclined arrangement of the oil pipe, the oil liquid flows to the first end at the lower part along the pipe wall, and the slag falls into the second auger 10 from the second end under the action of the auger blades, so that the oil content is reduced again. The second auger 10 also conveys the slag towards the slag discharge port 6 at a high position, and the first end is closed to temporarily store the oil flowing downwards, so that the oil content of the slag discharged from the slag discharge port 6 is less. Of course, oil collecting equipment positioned at the first ends of the first auger 9 and the second auger 10 can be arranged to recover residual oil after a period of treatment.
Because the slag still contains certain oil when being conveyed upwards to the slag discharge port 6 in the second auger 10, the oil slag can be further separated, so a backflow port 11 is also arranged on the lower surface of the second auger 10 in the embodiment and is positioned above the first-stage filtering and separating tank 1, the oil liquid can flow back into the first-stage filtering and separating tank 1 from the backflow port 11 when the second auger 10 is conveyed, the oil liquid also contains the slag, and the filtering and separating tanks 1 at all stages are used for separating again. And a multi-time circulation treatment mode is adopted, so that the oil content of the slag finally discharged from the slag discharge port 6 is less.
The circulating filtration type oil residue separation device provided by the embodiment can also be used in other fields and occasions similar to the occasions needing oil residue separation.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
