Description

Technical Field

[0001] The present application relates to the technical field of edible oil production and processing equipment, and specifically discloses a filtering device for edible oil. Background Art

[0002] Edible oil refers to animal or vegetable oils used in the process of making food. Edible oil is liquid at room temperature. Depending on the raw materials, processing technology and processing quality, most edible oils used in daily life are vegetable oils, including corn oil, peanut oil, hemp oil, corn oil, olive oil, camellia oil, canola oil and sunflower oil.

[0003] Now, with regard to camellia oil and its production process, in the prior art, the production of camellia oil includes the following process steps that are performed in sequence: drying camellia seeds, sorting camellia seeds, piling and bagging camellia seeds, and oil extraction from camellia seeds. During the drying, piling and bagging of camellia seeds, bran and other substances are added to the tea seed kernels of camellia seeds to increase the oil extraction rate of the tea seed kernels of camellia seeds. After the oil extraction is completed, the obtained camellia oil will contain the added bran and other substances, as well as the tea seed kernels of different volumes that are flattened and connected or granular after being pressed, which affect the quality of the camellia oil. Therefore, after the initial pressing is completed, the camellia oil after the initial pressing is filtered.

[0004] In the prior art, camellia oil is filtered by filtering equipment, which is classified into various types, including centrifugal filtering equipment, automatic filter screen filtering equipment and secondary press filtering equipment. Among them, for the automatic filter screen filtering equipment, in the prior art, the camellia oil is passed through the filter screen, and the impurities carried in the camellia oil are filtered out by the filter screen to obtain pure camellia oil, but the filtered impurities are still attached to the filter screen. As the filtering continues, the attached impurities will gradually increase and slow down the filtering speed of the camellia oil.

[0005] Some prior arts have added a timed collection structure for the impurities separated on the filter, but only this part of the impurities is collected and discharged to the outside, and the camellia oil contained in this part of the impurities will also be discharged together, resulting in a waste of camellia oil.

[0006] Therefore, in view of this, the inventor provides a filtering device for edible oil to solve the above-mentioned problems. Summary of the invention

[0007] The purpose of the present invention is to solve the problem that the camellia oil contained in the impurities cannot be effectively separated and utilized when the impurities separated on the filter are processed in the traditional camellia oil filtering equipment.

[0008] In order to achieve the above-mentioned purpose, the basic scheme of the present invention provides an edible oil filtering device, including an oil filter box and a secondary filtering and rolling structure arranged in the oil filter box for separating and refining impurities, and a driving member for driving the secondary filtering and rolling structure is arranged at the top of the oil filter box;

[0009] A second filter tank is provided on the bottom surface of the oil filter box, and a secondary filtering and rolling structure includes a first filter screen layer tensioned in the second filter tank and parallel to the inner bottom surface, a main shaft fixing tube coaxially fixed in the oil filter box, and a synchronous rotating structure rotatably connected to the inner wall of the oil filter box and fitted with two inner end surfaces of the oil filter box, the inner side of the synchronous rotating structure fits the outer wall of the main shaft fixing tube, and a plurality of oil filter slots are circumferentially provided, and oil push plates that can fit with the outer wall of the main shaft fixing tube are slidably connected in the oil filter slots, and a limiting member is fixed to the top of the oil push plate, and an oil inlet groove is provided on the end surface of the oil filter box above the first filter screen layer;

[0010] The main shaft fixing pipe is also provided with an oil discharge pipe and a slag discharge pipe in sequence along the rotation direction, which can be connected with the oil filter slot. A second filter layer with the same diameter as the outer wall of the main shaft fixing pipe is vertically tensioned in the port of the oil discharge pipe.

[0011] The top surface of the oil filter box is provided with a reciprocating driving groove for the limiter to slide into to fit the main shaft fixing pipe between the second filter screen layer and the slag discharge pipe. The width of the oil filter groove is smaller than the length of the main shaft fixing pipe between the oil discharge pipe and the slag discharge pipe.

[0012] Furthermore, it also includes an oil inlet box arranged above the oil filter box and connected to the oil filter box, an oil inlet conduit connected to the oil inlet box is fixedly connected to the top of the oil inlet box, and a driving member is fixedly connected to the upper end of the oil inlet box.

[0013] Furthermore, a primary crushing structure driven by a driving member and used for crushing large particles of impurities is provided in the oil inlet tank.

[0014] Furthermore, a filter plate is fixedly connected to the connection point between the oil inlet box and the oil filter box, and a plurality of first filter holes are opened on the filter plate. A primary crushing and filtering structure driven by a driving member and used for crushing large particles of impurities is provided in the oil inlet box.

[0015] Furthermore, a transition box is connected between the oil inlet box and the oil filter box, and a heating copper plate is arranged in the transition box.

[0016] Furthermore, the primary rolling and filtering structure is coaxially connected to the first ring platform in the oil inlet tank and driven by the driving member, and a plurality of partition push plates circumferentially fixed to the outside of the first ring platform, the top of the partition push plate is in contact with the top surface of the oil inlet tank, the outer wall of the partition push plate is in contact with the inner wall of the oil inlet tank, and a gap is left between the bottom end of the partition push plate and the bottom surface of the oil inlet tank, and the gap gradually decreases.

[0017] Furthermore, the bottom end of the partition push plate is fixedly connected to a transverse plate in the opposite direction of the rotation direction, and a plurality of passive rolling strips are distributed circumferentially along the radial direction on the inner bottom surface of the oil inlet tank, and a plurality of active rolling strips that can engage with the passive rolling strips are distributed along the radial direction on the lower end surface of the transverse plate.

[0018] Furthermore, the synchronous rotation structure includes a magnetic synchronous rotating ring rotatably connected to the inner wall of the oil filter box, a plurality of conical blocks circumferentially fixed to the inner side of the synchronous rotating ring and fitted to the outer wall of the main shaft fixed tube, an oil filter groove is formed between the conical blocks, and an oil push plate slidably connected in the oil filter groove is made of iron.

[0019] Furthermore, both inner end surfaces of the third filter tank are fixedly connected with a third adapter having an outer diameter equal to that of the main shaft fixing tube, and the second filter screen layer is fixedly connected and tensioned between the inner sides of the third adapter at both ends.

[0020] Furthermore, the reciprocating drive groove includes an arc-shaped pressing section for gradually pressing the oil push plate inward to approach the second filter layer, a horizontal pressing section for further pressing the push plate to fit the smooth transition section, and an arc-shaped return section for returning the oil push plate after leaving the slag discharge pipe.

[0021] The principle and effect of this scheme are:

[0022] 1. Compared with the prior art, after the oil containing impurities is introduced into the oil filter box, the driving member drives the synchronous rotating structure to rotate, so that the edible oil continuously enters the corresponding oil filter slot in batches. During the rotation process, the edible oil is first filtered through the first filter layer, so that the internal impurities adhere to the first filter layer. At the same time, as the synchronous rotating structure continues to rotate, the impurities attached to the first filter layer will be scraped off and placed in the corresponding oil filter slot, completing the preliminary edible oil filtering.

[0023] 2. Compared with the prior art, the present invention will push the oil push plate to move in the oil filter groove through the reciprocating driving groove when the synchronous rotating structure rotates. When the oil push plate is driven, the edible oil will be squeezed into the second filter layer by the oil push plate, and filtered through the second filter layer arranged on the side wall of the main shaft fixed tube, and impurities will be attached to the second filter layer. With the continuous rotation of the synchronous rotating structure, the oil push plate and the edible oil on the inside will move to the connection between the oil filter groove and the smooth transition section, and with the continuous push of the oil push plate, after the edible oil is filtered through the second filter layer, the remaining impurities will be squeezed by the oil push plate through the outer wall of the main shaft fixed tube between the oil discharge pipe and the slag discharge pipe to squeeze out the grease contained in the impurities and discharge it through the oil discharge pipe, which solves the problem that the traditional camellia oil filtering equipment cannot effectively separate and utilize the camellia oil contained in the impurities when processing the impurities separated on the filter.

[0024] 3. The present invention is provided with a synchronous rotating structure in the oil filter box, which can not only push the edible oil during the oil filtering process to accelerate the filtering speed of the edible oil, but also can separate the impurities remaining on the first filter layer after the edible oil is filtered through each oil filter chamber. With the rotation of the synchronous rotating structure, the impurities separated in each oil filter chamber and part of the edible oil are pushed to the second filter layer via the oil pushing plate. The oil contained in the impurities is squeezed out by continuously pushing the oil pushing plate and squeezing the outer wall of the main shaft fixed tube, thereby realizing effective impurity separation of camellia oil containing impurities, and refining the impurities to obtain the oil contained inside.

[0025] 4. The present invention is also provided with an oil inlet tank, and a primary rolling and filtering structure is installed in the oil inlet tank, which can crush large particles of impurities and separate the grease in the gaps between the large particles of impurities, so as to facilitate the subsequent squeezing of the oil push plate.

[0026] 5. The present invention is also provided with a magnetic synchronous rotating ring and an iron oil pushing plate, which can fix the oil pushing plate and the synchronous rotating ring after the oil pushing plate returns to its original position to prevent the oil pushing plate from moving during the subsequent process of loading edible oil into the oil filter slot.

[0034] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0035] The figure marks in the drawings of the specification include: oil inlet box 1, transition box 2, oil filter box 3, main shaft fixing pipe 4, oil outlet pipe 5, oil discharge pipe 6, slag discharge pipe 7, main shaft 8, inclined push plate 9, vertical push plate 10, cross plate 11, filter plate 12, first ring platform 13, partition 14, conical block 15, oil push plate 16, semicircular protrusion 17, first filter screen layer 18, cover plate 19, reciprocating drive groove 20, oil discharge slot 21, slag discharge slot 22, second filter screen layer 23.

[0036] A filter device for edible oil, for example Figure 1 As shown:

[0037] It includes an oil inlet box 1, a transition box 2 and an oil filter box 3. The oil inlet box 1, the transition box 2 and the oil filter box 3 are sequentially built from top to bottom to form a filtering device, and the oil inlet box 1 and the oil filter box 3 have the same diameter, and a main shaft 8 axial hole of equal diameter is opened in the middle. The oil inlet box 1 and the oil filter box 3 are connected by a main shaft fixing pipe 4.

[0038] A primary rolling and filtering structure is installed in the oil inlet box 1, and a secondary filtering and rolling structure is installed in the oil filter box 3. A motor mounting platform is installed on the top of the oil inlet box 1, and an axial hole is opened on the motor mounting platform. A driving motor is fixedly installed above the motor mounting platform, and the output shaft of the driving motor passes through the axial hole and is coaxially fixedly installed with a main shaft 8. The main shaft 8 extends into the main shaft fixing tube 4.

[0039] Specifically, Figure 2 As shown, an oil inlet conduit is installed on the left side of the oil inlet tank 1, and a first filter slot with an angle of 180° is opened at the bottom of the right side of the oil inlet tank 1. First adapters are respectively installed on the bottom plate of the oil inlet tank 1 on both sides of the first filter slot by screws, and a filter plate 12 with an angle of 180° is installed between the first adapters on both sides by screws. A circle of closed first annular groove is opened on the top of the section where the spindle fixing tube 4 extends into the oil inlet tank 1, and a circle of closed first internal meshing groove is opened on the end faces of the spindle fixing tube 4 on both sides of the first annular groove. A first ring platform 13 is installed between the spindle fixing tubes 4 on both sides of the first annular groove, and the first internal meshing platforms are respectively integrally formed on the end faces of both ends of the first ring platform 13. The first internal meshing platforms are respectively placed in the first internal meshing groove and can slide inside. The spindle fixing tubes 4 at the upper and lower ends are connected by the first ring platform 13. A first fixed rotating ring fixed to the first ring platform 13 by a connecting rod is also coaxially fixedly installed on the spindle 8.

[0040] At the same time, 12 partition push plates are circumferentially welded on the outer wall of the first ring platform 13, and every two partition push plates divide the internal chamber of the oil inlet tank 1 into an independent oil pushing chamber. The partition push plates include a vertical push plate 10, an inclined push plate 9 welded to the top of the vertical push plate 10 and uniformly inclined toward one side, and a bottom rolling plate welded to the bottom of the vertical push plate 10 and uniformly inclined toward the other side. The inner side of the top of the inclined push plate 9 is welded to the outer wall of the first ring platform 13.

[0041] In this embodiment, the outer walls of the vertical push plate 10, the inclined push plate 9 and the bottom rolling plate are respectively attached to the inner wall of the oil inlet tank 1, and the inner walls of the vertical push plate 10, the inclined push plate 9 and the bottom rolling plate are respectively attached to the outer wall of the spindle fixing tube 4, and the top of the inclined push plate 9 is respectively attached to the top inner wall of the oil inlet tank 1. In addition, a gap is left between the bottom end surface of the bottom rolling plate and the inner bottom surface of the oil inlet tank 1, and a horizontal plate 11 is welded to the bottom of the bottom rolling plate on one side of the inclined direction.

[0042] In this embodiment, a first filter hole is opened upward at the bottom of the filter plate 12, and the top of the first filter hole converges and penetrates the filter plate 12, so the upper diameter of the first filter hole is smaller than the lower diameter and transitions with a cone surface. On the remaining bottom surface of the oil inlet tank 1, a plurality of passive rolling blocks are arranged equidistantly in the radial direction, and a plurality of active rolling blocks are arranged equidistantly in the radial direction at the bottom end of the cross plate 11 and a section of the bottom rolling plate near the bottom end, and the active rolling blocks and the passive rolling blocks can fit each other.

[0043] Moreover, in this embodiment, the rotation direction of the partition push plate is controlled by the output shaft of the driving motor to be counterclockwise, and the oil inlet conduit is installed at a position just separated from the first filter tank along the rotation direction of the partition push plate. The edible oil to be filtered can be introduced into the oil inlet tank 1 through the oil inlet conduit. After the edible oil enters the oil inlet tank 1, it will be introduced into the corresponding oil pushing chamber by the inclined push plate 9. The impurities mixed in the edible oil will fall onto the inclined push plate 9 due to the gravity greater than the gravity of the edible oil and the continuous rotation of the partition push plate, and slide down the inclined push plate 9 with the flow of the edible oil, and slide into the bottom rolling plate along the vertical push plate 10. Since there is a gap between the bottom end of the bottom rolling plate and the bottom surface of the oil inlet box 1, the edible oil will also flow from the bottom gap during the rotation of the partition push plate, thereby increasing the fluidity of the edible oil and accelerating the flow of the internal mixed impurities, so that after entering the inner side of the bottom rolling plate, it gradually moves to the inner side of the horizontal plate 11, and the meshing of the active rolling strips and the passive rolling strips crushes the large pieces and large particles of connected impurities to form smaller impurity debris. Moreover, the internal gaps and impurities of the large pieces and large particles of connected impurities also contain grease, which is wrapped with edible oil. The grease contained in the impurity gaps can be discharged in advance through rolling, and the impurities can be crushed into debris.

[0044] During the continuous rotation of the partition push plate, the oil pushing chamber will move to the top of the filter plate 12, and flow down from the first filter hole to the transition box 2 below. When the crushed impurity debris is smaller than the top diameter of the first filter hole, it will flow down synchronously with the edible oil. When the crushed impurity debris is larger than the top diameter of the first filter hole, it will continue to move with the oil pushing chamber until it is repeatedly crushed to enter the transition box 2 below.

[0045] In this embodiment, the edible oil to be filtered is camellia oil. When the camellia oil is extracted, the camellia kernels inside will be squeezed and gathered. At the same time, in the process of extracting the camellia oil, some of the gathered camellia seeds will be discharged, and some small-volume camellia kernels will also be discharged. At the same time, the impurities may also contain substances such as Kangke.

[0046] like Figure 2 As shown, the transition box 2 is fan-shaped as a whole and is fixed between the oil inlet box 1 and the oil filter box 3 through the main shaft fixing tube 4. A fan-shaped groove is opened at the top of the transition box 2 to completely wrap the first filter tank, and an equal-angle fan-shaped groove is also opened at the bottom of the transition box 2 to connect the oil filter box 3. Three vertically arranged heating copper plates are also installed in the transition box 2, and mounting holes are opened on the outer wall of the transition box 2 for fixing the heating copper plates and supplying power to the heating copper plates.

[0047] like Figure 3 and Figure 4 As shown, a fan-shaped oil inlet groove with an angle of 180° is opened on the right side of the top of the oil filter box 3 and is connected to the fan-shaped groove of the transition box 2. A second filter tank with an angle of 180° is opened on the right side of the bottom end of the oil filter box 3. A second adapter is also installed on the bottom plate of the oil filter box 3 on both sides of the second filter tank by screws, and a fan-shaped first filter screen layer 18 with an angle of 180° is installed between the second adapters on both sides by screws. Three support bars are also fixedly installed radially on the inner wall of the second filter tank below the first filter screen layer 18. The first filter screen layer 18 is tightened by the second adapter and laid flat on the support bar for auxiliary support by the support bar. An oil outlet pipe 5 connected to the second filter tank is installed at the bottom end of the oil filter box 3.

[0048] In this embodiment, the top of the section where the spindle fixing tube 4 extends into the oil filter box 3 is also provided with a circle of closed second annular groove, and the end faces of the spindle fixing tube 4 on both sides of the second annular groove are respectively provided with a circle of closed second internal meshing groove, and a circle of closed second ring platform is installed between the spindle fixing tubes 4 on both sides of the second annular groove, and the second internal meshing platform is respectively integrally formed on both sides of the second ring platform from the end faces, and the second internal meshing platform is inserted into the second internal meshing groove and can slide inside. The spindle fixing tubes 4 at the upper and lower ends are connected by the second ring platform. A second fixed rotating ring connected to the second ring platform through a connecting rod is also coaxially fixedly installed on the spindle 8.

[0049] At the same time, thirteen conical blocks 15 are circumferentially welded on the outer wall of the second ring platform, and the inner end faces of the conical blocks 15 are respectively fitted to the outer wall of the second ring platform and the outer wall of the spindle fixing tube 4 below the second ring platform. A circle of closed magnetic synchronous swivels is also installed in the oil filter box 3, and the outer end faces of the conical blocks 15 are respectively welded to the inner wall of the synchronous swivels, and the synchronous swivels slide in line with the inner wall of the oil filter box 3. In addition, the inner walls of the two ends of the synchronous swivels and the conical blocks 15 are respectively fitted to the top and bottom inner walls of the oil filter box 3. In addition, the angle of the inner end of each conical block 15 is smaller than the angle of the outer end, and gaps are formed between adjacent conical blocks 15 as oil filter slots, and each oil filter slot is the same rectangular slot.

[0050] Specifically, Figure 3 As shown, a guide groove is opened in the radial direction at the top of the conical block 15 on both sides of the oil filter slot, and an oil push plate 16 containing a magnet is installed in the oil filter slot. The outer walls of the oil push plate 16 fit the oil filter slots on both sides, the outer wall of the oil push plate 16 fits the inner wall of the oil filter box 3, and the inner wall of the oil push plate 16 fits the outer wall of the second ring platform. A semicircular protrusion 17 is integrally formed at the center of the top of the oil push plate 16. Guide blocks that slide in the guide grooves are also integrally formed on both sides of the top of the oil push plate 16. The conical block 15, the synchronous swivel, and the oil push plate 16 form a synchronous rotation structure.

[0051] In this embodiment, the mechanism installed in the oil filter box 3, including the oil filter box 3, has only the synchronous rotating ring with magnetism, and the initial position of the oil push plate 16 is the position adsorbed on the inner side of the synchronous rotating ring. During the rotation of the synchronous rotating ring, the inner bottom surface of the conical block 15 will be in contact with the upper end surface of the first filter layer 18, so that the impurities attached to the first filter layer 18 and filtered out by the edible oil will be separated separately in the oil filter slots of each two adjacent conical blocks 15, and as the conical block 15 rotates, the impurities will be accumulated on one side or mixed in the subsequent edible oil to be filtered, reducing the blockage of the first filter layer 18 and increasing the fluidity of the edible oil.

[0052] A partition 14 is installed inside the spindle fixing tube 4 below the second ring stage, and the spindle 8 is rotatably mounted on the upper end surface of the partition 14, and the spindle fixing tube 4 is separated by the partition 14. A third filter tank is also opened backward along the rotation direction on the spindle fixing tube 4 at a section away from the second filter tank. A circular arc-shaped third transfer platform is also installed on the spindle fixing tube 4 at both ends of the third filter tank by screws, and a second filter screen layer 23 is fixedly installed between the third transfer platforms at both ends. In this embodiment, the outer end surface of the second filter screen layer 23 is connected to the outer end surface of the spindle fixing tube 4, and fits with the inner end surface of the conical block 15.

[0053] On the main shaft fixing tube 4, the outer wall of the end section of the third filter tank along the rotation direction is a smooth outer wall, which is a smooth transition section. A vertical slag discharge port is also opened on the main shaft fixing tube 4 where the smooth outer wall ends. The coverage length of the smooth outer wall is not greater than the width of the oil filter slot between the two conical blocks 15.

[0054] In this embodiment, a reciprocating driving groove 20 is also provided on the inner top surface of the oil filter box 3 located above the second filter tank and along the rotation direction of the main shaft 8, that is, on the cover plate 19 of the oil filter box 3. The semicircular protrusions 17 at the top of the oil push plate 16 can slide into the reciprocating driving groove 20 respectively, and the reciprocating driving groove 20 engages and pushes the oil push plate 16 to slide in the oil filter slot. Specifically, the shape of the reciprocating driving groove 20 is as follows: Figure 5 As shown, it includes five consecutive sections: a horizontal entry section, an arc-shaped pressing section, a horizontal pressing section, an arc-shaped return section and a horizontal slot exit section.

[0055] Among them, the horizontal entry section and the horizontal outlet section are the same as the initial position of the oil pushing plate 16, the arc-shaped entry section is used to push the oil pushing plate 16 toward the second filter layer 23, so that the inner wall of the oil pushing plate 16 fits with the second filter layer 23, the horizontal pressing section is used to press the oil pushing plate 16 against the smooth outer wall and slide on the smooth outer wall, and the arc-shaped return section is used to pull the oil pushing plate 16 back to the initial position.

[0056] In this embodiment, corresponding to the slag discharge port, an independent slag discharge pipe 7 is installed inside the main shaft fixed pipe 4. Corresponding to the second filter layer 23, an independent oil discharge pipe 6 is installed inside the main shaft fixed pipe 4.

[0057] Specifically, the horizontal entry section and the horizontal slot exit section are both arc sections, both of which are circular with the axis of the main shaft 8 as the center and have the same diameter. The arc entry section is used to push the oil push plate 16 located outside the oil filter slot toward the main shaft 8 and make it contact with the second filter layer 23, so as to discharge the edible oil in the oil filter slot through the second filter layer 23. When the oil push plate 16 moves to the end of the arc entry section, it can be squeezed into the horizontal pressing section.

[0058] like Figure 5 and Figure 6 As shown, the horizontal pressing section is divided into three continuous sections in the rotation direction of the main shaft 8: the laminating section, the pressing section and the slag discharge section. The laminating section, the pressing section and the slag discharge section are all coaxial with the main shaft 8, are arc-shaped sections, and the diameter of the laminating section remains unchanged. The diameter of the pressing section and the slag discharge section gradually decreases until the distance between the inner end surface of the oil baffle plate and the main shaft fixing tube 4 is less than the average thickness of a single camellia seed kernel.

[0059] In this embodiment, when the oil pushing plate 16 moves in the fitting section, the oil filter slot is still located inside the second filter screen layer 23. During the moving process, as the oil pushing plate 16 moves inward from the arc-shaped pressing section to the second filter screen layer 23, the amount of edible oil in the oil filter slot inside the oil pushing plate 16 decreases, but is not completely emptied. At the same time, impurities in the discharged edible oil will adhere to the second filter screen layer 23, be peeled off by the rotating conical block 15, and be mixed in the remaining edible oil.

[0060] When the oil push plate 16 moves to the pressing section, the inner side of the oil push plate 16 will move on the outer wall of the main shaft fixing tube 4, and in the process of continuous rotation, the conical block 15 enters the outer wall of the main shaft fixing tube 4 and fits with it, and at the same time, the remaining edible oil is completely discharged. Figure 6 As shown, the discharged oil is discharged through the second filter layer 23 connected to the top. When the oil pusher plate 16 moves inward from the pressing section, it squeezes and compacts the oily impurities brought out by the conical block 15, so that the grease inside is discharged and also discharged from the second filter layer 23 above. Moreover, the oil pusher plate 16 has completely discharged the edible oil inside before the oil filter slot where it is located is completely separated from the second filter layer 23, and has compacted and squeezed the oily impurities.

[0061] Afterwards, the oil pushing plate 16 enters the slag discharge section. With continuous pushing and rotation, the impurities removed by squeezing and oiling will be discharged into the slag discharge port for discharge, thus completing the filtering of the edible oil.

[0062] In the process of filtering edible oil, the impurities in the edible oil are first crushed by the primary rolling and filtering structure of the oil inlet box 1, and then crushed into small particles of impurities, which then flow into the oil filter box 3 through the transition box 2 simultaneously with the edible oil, and can also be heated by the heating copper plate in the oil filter box 3 to increase the fluidity of the edible oil. In this embodiment, the oil inlet box 1 will not leave behind or block the downstream flow of impurities, and only discharges the grease entrained between the impurity particles for large particles of impurities. After the edible oil carries small particles of impurities into the oil filter box 3, most of the edible oil is first removed by the second filter layer 23, and the small particles of impurities will be left on the first filter layer 18. Through the rotation of the conical block 15, the small particles of impurities are separately and separately brought into the position of the second filter layer 23. In this embodiment, the first filter layer 18 is placed horizontally and the second filter layer 23 is placed vertically. The edible oil in the oil filter groove of the adjacent conical block 15 is pushed out by the oil push plate 16 and filtered through the second filter layer 23. In the process of moving, the small particles of impurities are scraped off by the inner end of the conical block 15, and the oil push plate 16 is continuously pressed into the smooth transition section of the outer wall of the main shaft fixing tube 4 to squeeze out the grease in the small particles of impurities and discharge it through the oil discharge pipe 6 corresponding to the second filter layer 23. After that, during the continued rotation, the impurities will be pushed out from the slag discharge groove 22, completing the filtering of the edible oil, the separation of impurities and the refining of the grease inside the impurities.

[0063] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
