Description

Technical Field

[0001] This utility model relates to the field of Sichuan pepper oil processing technology, specifically a multi-stage filtration device for Sichuan pepper oil. Background Technology

[0002] In the industrial processing of Sichuan pepper oil, screw pressing is one of the core oil extraction technologies widely used in the industry. This process applies continuous and uniform pressure to the pre-treated Sichuan pepper raw materials using screw pressing equipment, causing the oil cells inside the pepper to break down, thereby separating and releasing the oil, laying the foundation for subsequent purification and processing of Sichuan pepper oil.

[0003] However, in the actual spiral pressing process, after the pepper raw material is crushed by compression, a large amount of pepper residue will inevitably be included in the oil. If these residues are not effectively removed, they will directly affect the sensory quality, storage stability and subsequent deep processing effect of the pepper oil. Therefore, the filtration treatment of the pressed pepper oil has become a crucial process in the pepper oil processing.

[0004] Currently, the industry commonly uses pressing filtration technology for filtering Sichuan pepper oil (for example, the Sichuan pepper oil pressing filtration device disclosed in Chinese patent application number CN202420948200.9). While this type of pressing filtration can separate Sichuan pepper oil from some of the residue to a certain extent, it has significant technical drawbacks in practical applications: Firstly, there is an irreconcilable contradiction between filtration precision and filtration efficiency. Because the mesh size of the filter components in existing pressing and filtering devices is fixed, while selecting a larger mesh size can improve filtration precision and effectively trap more fine particles, it also increases the flow resistance of the pepper oil, significantly reducing filtration efficiency and making it difficult to meet the efficiency requirements of large-scale industrial production. Conversely, while selecting a smaller mesh size can accelerate the filtration speed of the pepper oil and improve production efficiency, the filtration precision will decrease accordingly. Some fine particles cannot be effectively separated and will remain mixed in the pepper oil, causing turbidity and affecting the product's sensory quality and market competitiveness.

[0005] Secondly, continuous filtration of Sichuan pepper oil is not feasible due to its low level of automation. Existing pressing and filtration methods require manual shutdown and opening of the filter cylinder after each filtration cycle to remove the pressed cake and clean the filter components before the next filtration can begin. This process is not only cumbersome and time-consuming, but also leads to frequent production interruptions, preventing a continuous production flow and further reducing overall production efficiency. Furthermore, manual operation increases the risk of external contamination of the Sichuan pepper oil, compromising product quality stability. Utility Model Content

[0006] Therefore, to address the aforementioned shortcomings, this utility model provides a multi-stage filtration device for Sichuan pepper oil. This filtration device utilizes multiple layered filtration mechanisms, which can be equipped with filter screens of different mesh sizes to achieve multi-layer filtration of Sichuan pepper oil. This solves the problem of a single filter screen having a fixed mesh size. Simultaneously, a rotating mechanism penetrating the filtration mechanism can press and scrape the Sichuan pepper oil and impurities being filtered. Pressing extracts the oil, achieving the same effect as conventional pressing filtration. Scraping lifts the pressed oil cake that adheres tightly to the filter surface, preventing clogging of the filter holes and facilitating the oil to flow downwards through the filter holes, thus improving filtration efficiency. Finally, a discharge pipe at the outer end of the filtration mechanism can squeeze the oil cake out, enabling continuous operation of Sichuan pepper oil filtration.

[0007] This utility model is implemented as follows: a multi-stage filtration device for Sichuan pepper oil includes multiple filtration mechanisms connected together in layers. The cover is connected to the uppermost filter assembly and is equipped with a feed pipe; The receiving hopper is connected to the bottommost filter assembly; The rotating mechanism runs through multiple filter mechanisms and the cover, and presses and scrapes the material inside the filter mechanism by rotating.

[0008] Preferably, the receiving hopper has a conical structure and is provided with support legs at the bottom, which allow multiple filtration mechanisms to be placed horizontally.

[0009] Preferably, each of the filter mechanisms specifically includes a support cylinder; A connecting plate is provided on the outer side of both ends of the support cylinder and has connecting holes. The discharge pipe is installed on the side wall of the support cylinder; The filter disc is located on the inner wall of the support cylinder and has multiple filter holes evenly distributed on it.

[0010] Preferably, a discharge channel is provided inside the discharge pipe, one end of the discharge channel is connected to the inside of the support cylinder, and the other end of the discharge channel is set downwards, with the filter disc flush with the discharge channel.

[0011] Preferably, the filter holes of the filter discs in the plurality of filter mechanisms are of different sizes, and the size of the filter holes of the filter discs increases sequentially from bottom to top according to the installation order of the plurality of filter mechanisms.

[0012] Preferably, the rotating mechanism includes a drive motor and a rotating shaft. The rotating shaft passes through the center of the filter discs and the cover of the multiple filter mechanisms and maintains a rotatable connection. The drive motor is fixed to the cover and maintains a transmission connection with the rotating shaft. Several scrapers and rollers are arranged in layers at the outer end of the rotating shaft. Each layer of scrapers and rollers is arranged on the filter disc of each filter mechanism. One end of each scraper and roller is located at the outer end of the rotating shaft, and the other end is close to the inner wall of the support cylinder.

[0013] Preferably, the scraper is tilted and its bottom is kept close to the filter disc.

[0014] Preferably, a support rod is provided extending from the outer end of the rotating shaft, and the roller is rotatably disposed outside the support rod, with the bottom of the roller contacting the filter disc.

[0015] Compared with the prior art, the present invention has the following advantages: This filtration device, through the connection of multiple filtration mechanisms, can be equipped with filter screens of different mesh sizes to achieve multi-level filtration, breaking the limitation of a fixed mesh size for a single filter screen, balancing filtration accuracy and efficiency, and avoiding problems such as residue residue or slow filtration.

[0016] Meanwhile, the rotating mechanism running through the filtration system can press the peppercorn oil to ensure full oil output during rotation, while scraping the dough on the filter surface to prevent the filter holes from clogging, ensuring smooth oil flow and significantly improving filtration efficiency.

[0017] Furthermore, the dough cake can be squeezed out through the discharge pipe at the outer end of the filtration mechanism, eliminating the need for manual shutdown to remove the cake. This enables continuous production of Sichuan pepper oil filtration, reduces manual intervention, lowers the risk of contamination, and improves overall production efficiency and quality stability.

[0019] 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.

[0020] 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.

[0021] As described in the background section, existing pressing and filtering devices cannot simultaneously achieve both high-quality and efficient filtration because the mesh size of the filter screen is fixed. Furthermore, the pressed cake formed after filtration needs to be manually removed after the machine is stopped, which is not only troublesome but also poses certain safety hazards (if the pressing device suddenly starts when the cake is being removed, it is easy to squeeze the hand).

[0022] For the reasons stated above, please refer to the appendix for solutions to these problems. Figure 1 ~Appendix Figure 3 This utility model provides a multi-stage filtration device for Sichuan pepper oil, which includes multiple filtration mechanisms 1 connected together in layers; The cover 2 is connected to the uppermost filter assembly 1 and is equipped with a feed pipe 3; The receiving hopper 4 is connected to the bottom filter assembly 1; The rotating mechanism runs through multiple filter mechanisms 1 and the cover 2, and presses and scrapes the material inside the filter mechanism 1 by rotating.

[0023] In this embodiment, the receiving hopper 4 is a conical hopper structure, and a support leg 5 is provided at the bottom to allow multiple filter mechanisms 1 to be placed horizontally.

[0024] As mentioned above, placing the filter mechanism horizontally facilitates the pressing and filtering of the pepper oil falling from above, preventing the oil from flowing to the lower end. This ensures that the filtered oil can only flow downwards through the filter screen, thus achieving multi-layer filtration of the pepper oil.

[0025] Please see the appendix Figure 4 In this embodiment, each of the filter mechanisms 1 specifically includes a support cylinder 101; A connecting plate 102 is disposed on the outer side of both ends of the support cylinder 101 and has connecting holes thereon; The discharge pipe 103 is installed on the side wall of the support cylinder 101; The filter plate 104 is disposed on the inner wall of the support cylinder 101 and has a plurality of filter holes evenly formed on the filter plate 104.

[0026] As described above, multiple support cylinders 101 can be fastened together by setting the connection holes on the connecting plate, achieving a detachable connection and facilitating installation.

[0027] In this embodiment, a discharge channel 105 is provided inside the discharge pipe 103. One end of the discharge channel 105 is connected to the inside of the support cylinder 101, and the other end of the discharge channel 105 is set downward. The filter plate 104 is flush with the discharge channel 105.

[0028] As mentioned above, setting up a discharge channel facilitates the discharge of the pressed dough and can also prevent oil from being discharged to some extent.

[0029] Furthermore, to prevent grease from being discharged from the discharge channel, the bottom of the discharge channel can be set to be inclined, with its lowest end connected to the inside of the support cylinder and its highest end set downwards, but the inclination should not be too large, so that the dough can be discharged.

[0030] In this embodiment, the filter holes of the filter discs 104 in the plurality of filter mechanisms 1 are of different sizes, and the size of the filter holes of the filter discs 104 increases sequentially from bottom to top according to the installation order of the plurality of filter mechanisms 1.

[0031] As described above, by setting filter holes of different sizes, multi-layer filtration of Sichuan pepper oil can be achieved. After the top filter plate filters the oil, the oil contains Sichuan pepper residue, which falls to the filter plate below for further filtration. Repeating this process can achieve multi-layer filtration.

[0032] Please see the appendix Figure 5In this embodiment, the rotating mechanism includes a drive motor 6 and a rotating shaft 7. The rotating shaft 7 passes through the center of the filter discs 104 and the cover 2 of the multiple filter mechanisms 1 and maintains a rotatable connection. The drive motor 6 is fixed to the cover 2 and maintains a transmission connection with the rotating shaft 7. Several scrapers 8 and rollers 9 are arranged in layers at the outer end of the rotating shaft 7. Each layer of scrapers 8 and rollers 9 is arranged on the filter discs 104 of each filter mechanism 1. One end of the scrapers 8 and rollers 9 is arranged at the outer end of the rotating shaft 7, and the other end is close to the inner wall of the support cylinder 101.

[0033] In this embodiment, the scraper 8 is tilted and its bottom is kept close to the filter disc 104.

[0034] As described above, by setting the scraper at an angle and keeping its bottom close to the filter plate, firstly, the scraper continuously rotates and pushes the dough cake upwards after contacting it. Because the peppercorn fragments stick together during the pressing process, the dough cake that is stuck together is pushed upwards together, thus cleaning the filter holes of the filter plate. The pressed oil can then flow from the filter holes into the filtration mechanism below. Secondly, keeping the bottom of the scraper close to the filter plate avoids direct contact between the scraper and the filter plate. Since the scraper is moving while the filter plate is fixed, contact would cause wear and tear, resulting in mechanical debris that would flow into the peppercorn oil and affect its quality. Finally, by the scraper being close to the filter plate, the continuous scraping action of the scraper pushes the dough cake outwards, eventually leading to its discharge into the discharge channel, achieving self-cleaning of the dough cake and effectively realizing continuous operation of peppercorn oil filtration.

[0035] If mechanical debris caused by wear is not a concern, the bottom of the scraper 8 can be brought into contact with the filter disc 104. This method can effectively prevent the dough from clogging the filter holes.

[0036] In this embodiment, a support rod is provided extending from the outer end of the rotating shaft 7, and the roller 9 is rotatably disposed outside the support rod, with the bottom of the roller 9 contacting the filter disc 104.

[0037] As described above, the installation method of setting the rollers facilitates the squeezing of pepper oil and pepper residue on the filter disc, thereby squeezing the oil through the filter holes of the filter disc and dropping it into the filter mechanism or receiving hopper 4 at the lower end. This method increases the oil yield of pepper and improves the filtration efficiency.

[0038] In this embodiment, the outer ends of the cover 2 and the receiving hopper 4 are provided with connecting plates corresponding to the connecting plate 102, thereby connecting them into a whole and preventing grease from seeping out from the gaps.

[0039] 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.
