Description

Technical Field

[0001] This utility model relates to the field of oil processing technology, specifically to a circulating centrifugal separation device. Background Technology

[0002] Sichuan pepper oil can be produced by cold pressing and extraction. Cold pressing mainly involves pressing Sichuan peppers with a cold press to obtain Sichuan pepper oil. However, due to the cold pressing method, a large amount of Sichuan pepper residue will be present in the oil. In order to improve the quality of Sichuan pepper oil, a centrifugal separator is generally used to separate the Sichuan pepper oil and the residue.

[0003] Current centrifugal separation devices typically consist of a high-speed rotating centrifuge drum installed inside a container. The oil to be separated is poured into the centrifuge drum and rotates at high speed. Under the action of centrifugal force, the denser particles flow outwards, while the less dense particles flow inwards, thus achieving oil-liquid separation. This method can effectively filter out oil and water from Sichuan pepper oil. However, conventional centrifugal separation devices cannot achieve cyclic separation; they can only perform a single separation. This is because during the processing of Sichuan pepper oil (such as pressing and crushing), some Sichuan pepper residue will contain oil. Since the density of Sichuan pepper residue is roughly the same as that of Sichuan pepper oil, the Sichuan pepper residue will be discharged along with the Sichuan pepper oil during the separation process, thus affecting the quality of the Sichuan pepper oil. Utility Model Content

[0004] Therefore, in order to solve the above-mentioned shortcomings, this utility model provides a circulating centrifugal separation device. This centrifugal separation device sets a return pipe and a pump body on the discharge pipe of the centrifugal separation tank. Through the cooperation of the return pipe and the pump body, the separated oil and pepper residue can be pumped back into the centrifugal separation tank, thereby realizing multiple separations of oil. At the same time, the solid matter in the oil can be effectively filtered by controlling the pipeline to ensure the separation quality.

[0005] This utility model is implemented as follows: a circulating centrifugal separation device includes a centrifugal separation tank, inside which a rotating centrifugal separation cylinder is installed. The first discharge pipe is installed on the side wall of the centrifugal separator and corresponds to the first discharge port of the centrifugal separator cylinder; The second discharge pipe is located at the bottom of the centrifugal separator and corresponds to the second discharge port of the centrifugal separator cylinder; The return pipe has one end installed on the centrifugal separator tank and pointing towards the centrifugal separator cylinder, and the other end connected to the second discharge pipe through a control pipeline. The pump body is installed on the discharge pipe to return the material flowing in the second discharge pipe to the centrifugal separator along the return pipe.

[0006] Preferably, the centrifugal separator is provided with a cover at the top, and a feed pipe is provided on the cover. Both the feed pipe and the return pipe pass through the cover and point towards the centrifugal separator.

[0007] Preferably, the centrifugal separator has a centrifugal cylinder supported by a supporting flange on the inner wall of the centrifugal separator tank. The supporting flange and the inner wall of the centrifugal separator tank form a flow channel. The centrifugal cylinder is rotatably connected to the supporting flange by a top flange. There is a gap between the top of the centrifugal cylinder and the inner wall of the centrifugal separator tank. The gap and the flow channel form a first discharge port. The first discharge pipe is connected to the side wall of the centrifugal separator tank and is height-adapted to the flow channel. A second discharge port is opened at the center of the bottom of the centrifugal cylinder. A drive motor is also provided at the bottom of the centrifugal separator tank. The drive motor and the centrifugal cylinder are connected by gears.

[0008] Preferably, the control pipeline includes a first pipeline, a second pipeline, and a third pipeline. The first pipeline, the second pipeline, and the third pipeline are connected in parallel between the second discharge pipe and the return pipe. A tubular filter is also provided on the second pipeline.

[0009] Preferably, a discharge pipe is also connected to the return pipe.

[0010] Preferably, valves are installed on the first pipeline, the second pipeline, the third pipeline, the return pipe, and the discharge pipe.

[0011] Preferably, a pipe density meter is also provided on the second discharge pipe, and the pipe density meter is linearly connected to the valve.

[0012] Compared with the prior art, the present invention has the following advantages: 1. Improve separation efficiency and optimize resource utilization. This centrifugal separator can achieve the circulation and return of oil and pepper residue by setting a return pipe and pump body on the discharge pipe below the centrifugal separator tank. Compared with the single separation process, it greatly shortens the overall operation time. Through circulation separation, the residual oil in the pepper residue can be fully extracted, reducing raw material waste and increasing the oil yield.

[0013] 2. Ensure separation quality and improve product purity. Meanwhile, the oil can be filtered by controlling the pipeline to prevent debris from being discharged with the oil, directly improving the purity and cleanliness of the final oil product. Multiple circulation separations combined with precise filtration can effectively reduce the impurity content in the oil, reduce the pressure on subsequent purification processes, and indirectly ensure the quality stability of the product.

[0015] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation of this utility model and are not intended to limit this utility model in any way. The accompanying drawings in this utility model are only for illustrative purposes and to facilitate understanding of the embodiments and are not intended to limit this utility model in any way.

[0016] It should be noted that the structures, proportions, sizes, etc. shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0017] As described in the background section, existing centrifugal separation devices are all single-stage separation devices, resulting in poor separation effect. Especially when the feed volume is large, some oil may be mixed with water or debris, affecting the separation quality.

[0018] For the reasons stated above, please refer to the appendix for solutions to these problems. Figure 1 ~Appendix Figure 4 This utility model provides a circulating centrifugal separation device, including a centrifugal separation tank 1, which has a rotating centrifugal separation cylinder 16 inside; The first discharge pipe 4 is installed on the side wall of the centrifugal separator 1 and corresponds to the first discharge port of the centrifugal separator 16; The second discharge pipe 6 is located at the bottom of the centrifugal separator 1 and corresponds to the second discharge port of the centrifugal separator 16; The return pipe 14 has one end set on the centrifugal separator 1 and points to the centrifugal separator cylinder 16, and the other end is connected to the second discharge pipe 6 through a control pipeline. Pump body 7 is installed on discharge pipe 14 to return the material flowing in second discharge pipe 6 to centrifugal separator 16 along return pipe 14.

[0019] In this embodiment, the top of the centrifugal separator 1 is provided with a cover 2, and a feed pipe 3 is provided on the cover 2. Both the feed pipe 3 and the return pipe 14 pass through the cover 2 and point towards the centrifugal separator 16.

[0020] Please refer to the appendix carefully. Figure 4 In this embodiment, the centrifugal separator 1 has a centrifugal separator cylinder 16 supported by a support flange 18 on the inner wall of the centrifugal separator 1. The support flange 18 and the inner wall of the centrifugal separator 1 form a flow channel. The centrifugal separator cylinder 16 is rotatably connected to the support flange 18 by a top flange. There is a gap between the top of the centrifugal separator cylinder 16 and the inner wall of the centrifugal separator 1. The gap and the flow channel form a first discharge port. The first discharge pipe 4 is connected to the side wall of the centrifugal separator 1 and is adapted to the height of the flow channel. A second discharge port is opened at the bottom center of the centrifugal separator cylinder 16. A drive motor 5 is also provided at the bottom of the centrifugal separator 1. The drive motor 5 and the centrifugal separator cylinder 16 are connected by a gear 17.

[0021] As described above, a supporting flange is provided to support the centrifugal separator, which makes it convenient to set the centrifugal separator with a top opening for easy feeding, while the bottom can be driven by a transmission mechanism to rotate at high speed to realize the centrifugal separation process. At the same time, the flow channel between the supporting flange and the inner wall of the centrifugal separator is used to collect the separated denser objects (i.e., water in pepper oil) and discharge them directly from the first discharge pipe to avoid backflow into the centrifugal separator and affecting subsequent centrifugal separation.

[0022] Please refer to the appendix carefully. Figure 5 ~Appendix Figure 8In this embodiment, the control pipeline includes a first pipeline 9, a second pipeline 11 and a third pipeline 13. The first pipeline 9, the second pipeline 11 and the third pipeline 13 are connected in parallel between the second discharge pipe 6 and the return pipe 14. A tubular filter 12 is also provided on the second pipeline 11.

[0023] As mentioned above, a tubular filter can be installed to filter flowing grease.

[0024] In this embodiment, a discharge pipe 15 is also connected to the return pipe 14.

[0025] By setting up a discharge pipe, the grease can be discharged directly, avoiding its re-entry into the return pipe for centrifugal separation.

[0026] In this embodiment, valves 10 are provided on the first pipeline 9, the second pipeline 11, the third pipeline 13, the return pipe 14, and the discharge pipe 15.

[0027] In this embodiment, a pipe density meter 8 is also provided on the second discharge pipe 6, and the pipe density meter 8 is linearly connected to the valve 10.

[0028] As mentioned above, the purpose of installing a pipeline density meter is to detect whether there are solid impurities (i.e., peppercorn residue) in the oil, thereby determining whether filtration is necessary.

[0029] When using this centrifugal separator, the drive motor 5 is first started, which drives the centrifugal separator cylinder 16 to rotate via the gear 17. Then, the pepper oil to be separated is continuously fed into the centrifugal separator cylinder 16 through the feed pipe 3. As the centrifugal separator cylinder 16 rotates, the denser water is thrown to the inner wall, eventually overflowing from the top and flowing into the flow channel of the support flange 18, and then discharged from the first discharge pipe 4. The oil, due to its lower density, cannot flow upwards and can only continue to rotate at the bottom of the inner wall of the centrifugal separator cylinder 16, eventually being discharged from the second discharge pipe 6 at the bottom. During discharge, the flow of oil inside is monitored in real time by a pipe density meter 8. If there are no solids in the oil, it flows back through the first pipe 9 to the return pipe 14 and is then centrifuged again (see attached diagram). Figure 5 (The arrows indicate the direction of grease flow), or the grease passes through the first pipe 9 and the return pipe 14 and is discharged directly from the discharge pipe 15, thus removing the grease (see Appendix). Figure 7 If the grease contains solids, it flows in from the second pipe 11, passes through the tubular filter 12, and then flows into the return pipe 14, finally entering the centrifugal separator 16 for further centrifugation (see attached diagram). Figure 6 ).

[0030] When the tubular filter 12 needs cleaning (i.e., when the filter screen is clogged and needs cleaning), the internal grease is first drained, and then cleaning liquid (such as grease remover) is introduced into the pipeline. The cleaning liquid flows into the first pipeline 9 and then flows in reverse to the second pipeline 11 to backwash the tubular filter 12, flushing out the solids clogging the filter screen. Then, the cleaning liquid mixed with solids flows to the third pipeline 13 and then flows into the return pipe 14 to be discharged from the discharge pipe 15 or flows back into the centrifugal separator 16, thus cleaning the tubular filter 12 (see attached). Figure 8 ).

[0031] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
