Description

Technical Field

[0001] The present invention relates to the technical field of camellia oil processing, and more specifically, to a camellia oil pressing device that is efficient and has a fine filtering function. Background Art

[0002] Camellia oil is obtained from the seeds of Camellia oleifera Abel in the Theaceae family. To obtain camellia oil, first, the collected tea seeds need to be dried in the sun. Secondly, the tea seeds are ground into powder. Then, heat treatment is carried out. Next, the heated tea seed powder is poured into a tea cake mold, and the outside is wrapped with rice straw for shaping. The operating machine is slightly pressed into shape. After that, the tea cake molds are neatly placed on the oil press, and a press is used to extract camellia oil. The extracted camellia oil is filtered and then packed into barrels. However, after the camellia oil is pressed, a large amount of wet oil residue is generated. The wet oil residue still contains some camellia oil. Usually, the wet oil residue is further pressed. However, pressing the wet oil residue often increases production costs and time, and the oil yield is not high, and the quality is far inferior to the camellia oil obtained from the first pressing. However, when multiple presses are carried out in the same device, the camellia oil from the first pressing and the camellia oil from the subsequent pressing are mixed together, affecting the quality of the camellia oil. If the wet oil residue is transferred and then pressed, it will increase production costs and burdens. Therefore, it is necessary to provide a camellia oil pressing device that is efficient and has a fine filtering function to solve the problems raised in the above background art. Summary of the Invention

[0003] To achieve the above object, the present invention provides the following technical solution: A camellia oil pressing device that is efficient and has a fine filtering function, comprising:

[0004] A carrying frame for carrying the pressing device;

[0005] A collecting tray fixed on the carrying frame and divided into an inner part and an outer ring part, each provided with a discharge port;

[0006] A pressing cylinder fixed in the collecting tray and located at the junction of the inner part and the outer ring of the collecting tray;

[0007] A pressing plate fixed inside the pressing cylinder, and a plurality of groups of through holes are provided on the pressing plate, and each group of through holes is composed of a plurality of annularly distributed through holes;

[0008] A filtering component corresponding to the through holes and slidably arranged up and down in the through holes;

[0009] A hydraulic press fixed on the top of the carrying frame, located directly above the pressing cylinder, and a hydraulic shaft is fixed on the hydraulic press;

[0010] A hydraulic plate corresponding to the pressing cylinder, the top of which is fixedly connected to the hydraulic shaft, and connection holes corresponding to the through holes are provided on the hydraulic plate;

[0011] A moving adjustment device, movably arranged above the hydraulic plate;

[0012] A stirring assembly, fixed to the bottom of the moving adjustment device and slidably connected to the connection hole.

[0013] Further, preferably, secondary filtering mechanisms are respectively provided in the middle part and the outer ring of the collection tray, and the secondary filtering mechanisms are located above the discharge outlet of the collection tray. That is to say, when initially pressing the raw material, the squeezed tea oil is initially filtered by the filtering assembly, then flows into the middle position of the collection tray, and after being secondarily filtered by the secondary filtering mechanism, it is discharged from the discharge outlet for collection and filling. When secondarily pressing the oil residue, the squeezed tea oil flows out from the side of the pressing cylinder body, enters the outer ring position of the collection tray, and after being secondarily filtered by the secondary filtering mechanism, it is discharged through the discharge outlet for collection and filling, which not only ensures the quality of the tea oil but also efficiently extracts the tea oil from the raw material.

[0014] Further, preferably, the pressing cylinder body includes:

[0015] An isolation cylinder, fixed to the collection tray, isolating the middle part and the outer ring of the collection tray;

[0016] A limiting ring, fixed above the isolation cylinder and fixedly connected to the pressing disc;

[0017] A side filtering ring surface, which is a double-layer structure and fixed to the top of the limiting ring;

[0018] A closing ring, slidably arranged between the side filtering ring surfaces. That is to say, under the action of the limiting ring, the pressing disc is fixed. When initially pressing the raw material, the closing ring moves down between the side filtering ring surfaces to close the side filtering ring surfaces, and then the filtering assembly moves up and is inside the raw material. When the hydraulic plate moves down under the action of the hydraulic press for pressing, while the hydraulic plate presses the raw material, it drives the filtering assembly to move down in the through hole. The squeezed tea oil is initially filtered by the filtering assembly and then flows into the interior of the isolation cylinder, that is, the middle part of the collection tray, and after being secondarily filtered, it is discharged through the discharge outlet; when secondarily pressing the oil residue, the filtering assembly is driven to move down by the moving adjustment device to close the through hole, and then the oil residue is dispersed and stirred by the stirring assembly. After the stirring is completed, the stirring assembly is retracted, and the closing ring is moved up to open the side filtering ring surfaces. Then the hydraulic press drives the hydraulic plate to move down to secondarily press the oil residue on the pressing disc. The squeezed tea oil flows out after being filtered by the side filtering ring surface and enters the outer ring part of the collection tray, and after being secondarily filtered, it is discharged through the discharge outlet, fully extracting and filtering the tea oil while ensuring the quality of the tea oil.

[0019] Further, preferably, the filtering assembly includes:

[0020] The filter screen is annular and is slidably connected to the through hole on the pressure plate on the outside;

[0021] The filtering circular surface is fixed to the bottom of the filter screen and is located below the pressure plate;

[0022] The magnet is fixed to the top of the filter screen, and the diameter of the magnet is the same as the diameter of the through hole on the pressure plate. When the hydraulic press drives the hydraulic plate to move downward to initially press the raw materials on the pressure plate, at the same time, the hydraulic plate fits with the magnet at the top of the filter assembly, driving the filter screen to slide in the through hole. During the continuous downward movement of the hydraulic plate, the pressed tea oil flows along the side wall of the filter screen into the interior of the filter assembly, and then passes through the filtration of the filtering circular surface and flows into the middle position of the collection tray. After secondary filtration, it is discharged through the discharge port. It should be noted that there is friction between the filter screen and the through hole, and it can only move up and down under the action of an external force.

[0023] Further, as a preference, the movement adjustment device includes:

[0024] The long gear is correspondingly arranged with the connection hole on the hydraulic plate, is slidably arranged in the connection hole, and the bottom of the long gear is fixedly connected to the stirring assembly, and a control mechanism is arranged inside;

[0025] The rotating assembly is rotatably arranged on the top of the hydraulic plate, is located between two groups of long gears, and is rotatably connected to the long gears;

[0026] The adjustment panel is fixed to the top of the long gear;

[0027] A plurality of electric telescopic shafts are annularly distributed and are arranged between the rotating assembly and the hydraulic shaft; and the electric telescopic shafts are fixedly connected to the adjustment panel and the hydraulic plate. That is to say, under the action of the electric telescopic shafts, when the electric telescopic shafts extend, the adjustment panel moves upward, and at the same time drives the long gears and the stirring assembly to move upward in the connection hole. When the electric telescopic shafts contract, the adjustment panel moves downward, and at the same time drives the long gears and the stirring assembly to move downward in the connection hole. The position of the filter assembly in the through hole is adjusted by the up and down movement of the long gears and the stirring assembly, and the position of the stirring assembly in the oil residue is adjusted to facilitate the full dispersion and stirring of the oil residue. And under the drive of the rotating assembly, the stirring assembly is driven to rotate by the long gears to stir the oil residue.

[0028] Further, as a preference, the rotating assembly includes:

[0029] The internal gear ring is rotatably arranged on the hydraulic plate and meshes with the inner long gear;

[0030] The external gear ring is rotatably arranged on the hydraulic plate and meshes with the outer long gear;

[0031] The connecting rod fixedly connects the internal gear ring and the external gear ring. That is to say, under the action of the connecting rod, the internal gear ring and the external gear ring rotate simultaneously, driving the two adjacent sets of long gears to rotate in opposite directions, and further driving the corresponding stirring components to rotate in opposite directions to disperse and stir the oil residue.

[0032] Further, as a preference, the external gear ring meshes with the rotating gear on the external rotating motor. The rotating motor is fixed on the hydraulic plate and is located between the two long gears. That is to say, driven by the rotating motor, the external gear ring is driven to rotate through the rotating gear, and then the internal gear ring is driven to rotate synchronously through the connecting rod, driving the two adjacent sets of long gears and the stirring components to rotate in opposite directions to disperse and stir the oil residue.

[0033] Further, as a preference, the stirring component includes:

[0034] The central shaft is fixed at the bottom center of the long gear;

[0035] The fixed top cap is fixed at one end of the central shaft extending out of the long gear;

[0036] The moving part is slidably arranged on the central shaft;

[0037] The moving sleeve shaft is slidably arranged on the central shaft, is slidably connected with the long gear, is fixedly connected with the moving part at one end, and is controlled by the internal control mechanism of the long gear at the other end;

[0038] The electromagnet is fixed at the bottom of the fixed top cap, and the diameter of the electromagnet is the same as the diameter of the connection hole on the hydraulic plate;

[0039] The connecting rods are in an "X" shape, and a plurality of them are annularly distributed. One side of each connecting rod is respectively fixed on the fixed top cap and the moving part;

[0040] Arc-shaped stirring blades are provided in a circular distribution with multiple ones, and the convex surface of the arc-shaped stirring blade is fixedly connected to the side of the connecting rod away from the central axis. That is to say, when the hydraulic press drives the hydraulic plate to move downward to initially press the raw materials on the pressure plate, at this time, the electromagnet at the bottom of the stirring assembly closes the connection hole on the hydraulic plate, presses the raw materials through the hydraulic plate, and at the same time drives the filtering assembly to move downward. After the initial pressing is completed, the electric telescopic shaft drives the adjustment panel to move downward, drives multiple stirring assemblies to move downward through the long gear, drives the filtering assembly to move downward in the through hole, closes the through hole through the magnet at the top of the filtering assembly, then the hydraulic press drives the hydraulic plate to move upward, and the stirring assembly disengages from the filtering assembly. Then, the internal control device of the long gear controls the moving sleeve shaft to move downward on the central axis, thereby driving the moving part to move on the central axis, driving the arc-shaped stirring blade to expand outward through the connecting rod, thereby driving the long gear to rotate through the rotating assembly, further driving the arc-shaped stirring blade to rotate inside the oil residue, and adjusting the vertical position through the electric telescopic shaft to disperse and stir the oil residue, changing its internal structure and porosity, which is beneficial to the seepage of residual oil during the secondary pressing. After the stirring is completed, the moving sleeve shaft drives the moving part to move upward on the central axis, drives the arc-shaped stirring blade to retract through the connecting rod, and then the electric telescopic shaft drives the long gear and the stirring assembly to move upward, so that the electromagnet at the bottom of the stirring assembly closes the connection hole, presses the oil residue through the hydraulic plate for secondary pressing. After the pressing is completed, the oil residue is cleared out, and the electromagnet at the bottom of the stirring assembly adsorbs the magnet at the top of the filtering assembly, driving the filtering assembly to move upward and pulling the filtering assembly out of the through hole for the next use.

[0041] Compared with the prior art, the beneficial effects of the present invention are:

[0042] In the present invention, through the function of the pressing cylinder body, the tea oil obtained from the first pressing and the tea oil obtained from the second pressing are respectively transported and filtered, fully extracting the tea oil in the raw materials and ensuring the quality of the tea oil; through the filtering assembly, the tea oil extracted for the first time is filtered and transported, and after secondary filtering in the middle of the collection tray, it is collected and stored; through the setting of the moving and adjusting device, the stirring assembly is moved up and down for adjustment, and the raw materials after the first pressing are dispersed and stirred, changing their internal structure and porosity, which is beneficial to the seepage of residual oil during the secondary pressing.

That is to say, when the raw material is initially pressed, the squeezed tea oil is initially filtered by the filtering assembly 5, then flows into the middle position of the collecting tray 2, and after being secondarily filtered by the secondary filtering mechanism, it is discharged from the discharge port for collection and filling. When the oil residue is secondarily pressed later, the squeezed tea oil flows out from the side of the pressing cylinder body 3, enters the outer ring position of the collecting tray 2, and after being secondarily filtered by the secondary filtering mechanism, it is discharged through the discharge port for collection and filling, which not only ensures the quality of the tea oil but also can efficiently extract the tea oil from the raw material.

When the raw material is initially pressed, the closed ring 34 moves downward between the side filter ring surfaces 33 to close the side filter ring surfaces 33. Then the filter assembly 5 moves upward and is located inside the raw material. When the hydraulic plate 7 moves downward under the action of the hydraulic press 6 for pressing, while the hydraulic plate 7 presses the raw material, it drives the filter assembly 5 to move downward in the through hole 41. The squeezed tea oil flows into the interior of the isolation cylinder 31, that is, the middle part of the collection tray 2, after being preliminarily filtered by the filter assembly 5, and is discharged through the discharge port after secondary filtration. When the oil residue is pressed again, the filter assembly 5 is driven to move downward by the moving adjustment device 8 to close the through hole 41. Then the oil residue is dispersed and stirred by the stirring assembly 9. After the stirring is completed, the stirring assembly 9 is retracted, and the closed ring 34 is moved upward to open the side filter ring surfaces 33. Then the hydraulic press 6 drives the hydraulic plate 7 to move downward to press the oil residue on the pressing plate 4 again.

When the hydraulic press 6 drives the hydraulic plate 7 to move downward to initially press the raw material on the pressing plate 4, at the same time, the hydraulic plate 7 is in contact with the magnet 53 at the top of the filter assembly 5, driving the filter net 51 to slide in the through hole 41. During the continuous downward movement of the hydraulic plate 7, the squeezed tea oil flows along the side wall of the filter net 51 into the interior of the filter assembly 5, and then passes through the filtration of the filter circular surface 52 and flows into the middle position of the collection tray 2, and is discharged through the discharge port after secondary filtration. It should be noted that there is friction between the filter net 51 and the through hole 41, and it can move up and down only under the action of an external force.

[0075] A plurality of electric telescopic shafts 84 are annularly distributed and arranged between the rotating assembly 82 and the hydraulic shaft 61; and the electric telescopic shafts 84 are fixedly connected to the adjusting panel 83 and the hydraulic plate 7. That is to say, under the action of the electric telescopic shafts 84, when the electric telescopic shafts 84 extend, the adjusting panel 83 moves upward, and at the same time drives the long gears 81 and the stirring assembly 9 to move upward in the connection hole 71. When the electric telescopic shafts 84 contract, the adjusting panel 83 moves downward, and at the same time drives the long gears 81 and the stirring assembly 9 to move downward in the connection hole 71. The position of the filtering assembly 5 in the through hole 41 is adjusted by the up and down movement of the long gears 81 and the stirring assembly 9, and the position of the stirring assembly 9 in the oil residue is adjusted to facilitate the full dispersion and stirring of the oil residue. And driven by the rotating assembly 82, the stirring assembly 9 is driven to rotate by the long gears 81 to stir the oil residue.

[0080] In this embodiment, the external tooth ring 822 meshes with the rotating gear on the external rotating motor. The rotating motor is fixed on the hydraulic plate 7 and is located between the two long gears 81. That is to say, driven by the rotating motor, the external tooth ring 822 is driven to rotate by the rotating gear, and then the internal tooth ring 821 is driven to rotate synchronously through the connecting rod 823, driving two adjacent sets of long gears 81 and the stirring assembly 9 to rotate in opposite directions to disperse and stir the oil residue.

[0081] In this embodiment, the stirring assembly 9 includes:

[0082] The central shaft 91 is fixed at the bottom center of the long gear 81;

[0084] A moving member 93 is slidably arranged on the central shaft 91;

[0085] A moving sleeve shaft 94 is slidably arranged on the central shaft 91, is slidably connected to the long gear 81, is fixedly connected to the moving member 93 at one end, and is controlled by an internal control mechanism of the long gear 81 at the other end;

[0086] An electromagnet 95 is fixed to the bottom of the fixed top cap 92, and the diameter of the electromagnet 95 is the same as the diameter of the connection hole 71 on the hydraulic plate 7;

[0088] Arc-shaped stirring blades 97 are annularly distributed in multiple numbers, and the convex surfaces of the arc-shaped stirring blades 97 are fixedly connected to the side of the link rods 96 far from the central shaft 91. That is to say, when the hydraulic press 6 drives the hydraulic plate 7 to move downward to initially press the raw materials on the pressing disc 4, at this time, the electromagnet 95 at the bottom of the stirring assembly 9 closes the connection hole 71 on the hydraulic plate 7, presses the raw materials through the hydraulic plate 7, and at the same time drives the filtering assembly 5 to move downward. After the initial pressing is completed, the electric telescopic shaft 84 drives the adjusting panel 83 to move downward, drives multiple stirring assemblies 9 to move downward through the long gear 81, drives the filtering assembly 5 to move downward in the through hole 41, closes the through hole 41 through the magnet 53 at the top of the filtering assembly 5, then the hydraulic press 6 drives the hydraulic plate 7 to move upward, the stirring assembly 9 disengages from the filtering assembly 5, and then the internal control device of the long gear 81 controls the moving sleeve shaft 94 to move downward on the central shaft 91, thereby driving the moving member 93 to move on the central shaft 91, driving the arc-shaped stirring blades 97 to expand outward through the link rods 96, thereby driving the long gear 81 to rotate through the rotating assembly 82, driving the arc-shaped stirring blades 97 to rotate inside the oil residue, and adjusting the up and down position through the electric telescopic shaft 84 to disperse and stir the oil residue, so that its internal structure and porosity change, which is beneficial to the seepage of residual oil during the secondary pressing. After the stirring is completed, the moving sleeve shaft 94 drives the moving member 93 to move upward on the central shaft 91, drives the arc-shaped stirring blades 97 to retract through the link rods 96, and then the electric telescopic shaft 84 drives the long gear 81 and the stirring assembly 9 to move upward, so that the electromagnet 95 at the bottom of the stirring assembly 9 closes the connection hole 71, presses the oil residue through the hydraulic plate 7. After the pressing is completed, the oil residue is cleared out, and the electromagnet 95 at the bottom of the stirring assembly 9 adsorbs the magnet 53 at the top of the filtering assembly 5, drives the filtering assembly 5 to move upward, and pulls the filtering assembly 5 out of the through hole 41 for the next use.

[0089] During specific implementation, first, the tea seeds are ground into powder, then heat-treated, and the heat-treated tea seed powder is poured into a tea cake mold and wrapped with rice straw on the outside for shaping. The operating machine slightly compresses it into shape. When shaping, holes corresponding to the filtering component 5 are left in the tea cake. Then, the tea cake is placed on the pressing plate 4 so that the holes in the tea cake correspond to the filtering component 5 one by one. Then, the side filtering ring surface 33 is sealed by the sealing ring 34. The electric telescopic shaft 84 drives the long gear 81 to move upward, and the connecting hole 71 on the hydraulic plate 7 is sealed by the electromagnet 95 at the bottom of the stirring component 9. Then, the hydraulic press 6 drives the hydraulic plate 7 to move downward to fit with the magnet 53 at the top of the filtering component 5. During the continuous downward movement of the hydraulic plate 7, the tea cake is squeezed to extract tea oil, and the filtering component 5 is driven to move downward in the through hole 41. The extracted tea oil flows along the side wall of the filter screen 51 into the interior of the filtering component 5, and then passes through the filtration of the filtering circular surface 52 and flows into the middle position of the collection tray 2. After secondary filtration, it is discharged through the discharge port. After the primary pressing of the tea cake is completed, the electric telescopic shaft 84 drives the adjusting panel 83 to move downward, and the long gear 81 drives multiple stirring components 9 to move downward, driving the filtering component 5 to move downward in the through hole 41. The through hole 41 is sealed by the magnet 53 at the top of the filtering component 5. Then, the hydraulic press 6 drives the hydraulic plate 7 to move upward, and the stirring component 9 is separated from the filtering component 5. Then, the internal control device of the long gear 81 controls the moving sleeve shaft 94 to move downward on the central shaft 91, thereby driving the moving part 93 to move on the central shaft 91. The arc-shaped stirring blade 97 is driven to expand outward through the connecting rod 96. Then, the rotating motor is started, and the external tooth ring 822 is driven to rotate through the rotating gear. Then, the internal tooth ring 821 is driven to rotate synchronously through the connecting rod 823, driving the adjacent two groups of long gears 81 and stirring components 9 to rotate in the opposite direction. The arc-shaped stirring blade 97 dispersedly stirs the oil residue, changing its internal structure and porosity, which is beneficial for the exudation of residual oil during the secondary pressing. After the stirring is completed, the moving sleeve shaft 94 drives the moving part 93 to move upward on the central shaft 91, and the arc-shaped stirring blade 97 is driven to retract through the connecting rod 96. Then, the electric telescopic shaft 84 drives the long gear 81 and the stirring component 9 to move upward, so that the electromagnet 95 at the bottom of the stirring component 9 seals the connecting hole 71. Then, the sealing ring 34 is moved upward to open the side filtering ring surface 33. The oil residue is secondarily pressed by the hydraulic plate 7, and the extracted tea oil is filtered and flows out through the side filtering ring surface 33 and enters the outer ring part of the collection tray 2. After secondary filtration, it is discharged through the discharge port. After the pressing is completed, the oil residue is cleared out, and the filtering component 5 is adsorbed by the electromagnet 95 at the bottom of the stirring component 9 on the magnet 53 at the top of the filtering component 5, driving the filtering component 5 to move upward and pulling the filtering component 5 out of the through hole 41 for the next use.
