Description

Technical Field

[0001] This utility model relates to the field of tea oil processing technology, and in particular to a flat rotary extractor for tea oil production. Background Technology

[0002] Camellia oil, also known as tea seed oil, is a vegetable oil extracted from the seeds (camellia seeds) of the camellia tree. The main production methods for camellia oil include cold pressing, hot pressing, and solvent extraction. Among these, the rotary extractor is the core equipment for the solvent extraction method of camellia oil production.

[0003] The rotary extractor consists of a feeding device, a rotating body, a screw conveyor for discharging meal, a mixed oil circulation pump, a speed regulating device, a fixed grid bottom, spray heads, and a central rotating shaft. The principle of the rotary extractor is as follows: Inside the cylindrical shell of the rotary extractor, there is a hollow concentric rotating body. At the center of the rotating body is a vertical rotating shaft. The rotating body is divided into several fan-shaped extraction compartments, i.e., material compartments, by many radial baffles. Each material compartment is a unit for holding the oil to be extracted. The sprayed solvent (or mixed oil) is sprayed down from the spray heads above the material compartments via their respective mixed oil circulation pumps, performing counter-current spraying and soaking on the material in each compartment. After permeation through the material layer and through the fixed grid bottom, it flows into several mixed oil collection compartments below. After multiple cycles of spraying and soaking of the material, the high-concentration mixed oil is filtered to remove fine meal debris and then pumped into a mixed oil storage tank. The wet meal with low residual oil falls through the fan-shaped meal outlets at the bottom of the grid and is sent to the wet meal desolventizing system. The entire rotating body of the horizontal rotary leaching tank is in a fully enclosed shell and system. The feeding device above the shell consists of a sealed screw conveyor and a gravity gate, forming a material sealing effect. The rotating body of the horizontal rotary leaching tank is driven by a transmission device. By changing the rotation speed of the rotating body, it can adapt to different leaching conditions.

[0004] Current rotary leaching equipment consists of multiple oil pipes and nozzles inserted into the shell. Each nozzle sprays its own area. However, because the material compartment in the rotating body is a fan-shaped area, and the spray volume and spraying time of each nozzle are the same, during the rotation of the rotating body, the larger areas in the fan-shaped area are sprayed with insufficient solvent, while the smaller areas near the central fixed axis are sprayed with excessive solvent. This makes it difficult for the oil in the fan-shaped area to come into uniform contact with the solvent and soak, resulting in inconsistent oil extraction in the same area. This not only easily leads to oil waste but also increases operating costs.

[0005] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the prior art that when the nozzle sprays solvent in a fan-shaped area, the oil in the fan-shaped area is difficult to contact the solvent evenly with the solvent as the rotating body rotates, which easily leads to oil waste. Therefore, a flat rotary extractor for tea oil production is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A rotary extractor for tea oil production includes a fixed shaft, on which a rotating body is coaxially rotatably mounted. The rotating body has several fan-shaped material compartments and multiple first spray rods, each fixedly connected to one end of the rotating body extending from the fixed shaft. Second spray rods are rotatably mounted on both sides of the free ends of the multiple first spray rods. Multiple nozzles are fixedly mounted at the bottom of both the first and second spray rods. The first spray rods and the second spray rods on both sides form a trident-shaped structure. When the rotating body rotates, the second spray rods, carrying the nozzles, oscillate back and forth.

[0009] To facilitate the rotatable connection between the second spray bar and the first spray bar, preferably, a rotating seat is fixedly provided on both sides of the first spray bar, and a rotating shaft is fixedly provided at one end of the second spray bar, with the rotating shaft rotatably connected to the rotating seat.

[0010] To facilitate the rotation of the second spray bar around the axis of the rotating shaft, a push plate is slidably mounted on the first spray bar. Limiting plates are fixedly mounted on both sides of the push plate, and a rack is fixedly mounted on the end of the limiting plate away from the push plate. A first gear is fixedly mounted on the rotating shaft, and the first gear is slidably connected to the corresponding rack. The first spray bar is also provided with a driving part for driving the push plate to slide.

[0011] In order to drive the push plate to slide back and forth, the driving unit further includes a reciprocating screw. A groove is provided at one end of the first spray bar near the fixed shaft. The reciprocating screw is rotatably disposed in the groove. One end of the push plate extending into the groove cooperates with the reciprocating screw. When the reciprocating screw rotates, it drives the push plate to slide back and forth along the groove.

[0012] Furthermore, an end face gear is fixedly installed on the top of the rotating body, a rotating shaft is fixedly installed at one end of the reciprocating screw, and a second gear is fixedly installed on the rotating shaft, the second gear meshing with the end face gear.

[0013] Furthermore, limit grooves are provided on both sides of the first spray bar, and the limit plate is slidably disposed in the limit groove.

[0014] Compared with the prior art, this utility model provides a flat rotary extractor for tea oil production, which has the following beneficial effects:

[0015] 1. The flat rotary extractor for tea oil production has a second spray bar that is rotated on both sides of the first spray bar. The second spray bar is located in the fan-shaped area away from the central axis. Both the first and second spray bars are equipped with nozzles. When the rotating body rotates, the second spray bar swings back and forth with the nozzles to spray the solvent. This can achieve a more uniform spraying of the solvent in all parts of the fan-shaped area, so that the oil and solvent in the same compartment can be evenly contacted, which can avoid the waste of oil and improve the use effect.

[0016] 2. The flat rotary extractor used in tea oil production has an end face gear fixedly installed on the rotating body and a second gear fixedly installed on the reciprocating screw. During the rotation of the rotating body, the end face gear and the second gear mesh to drive the reciprocating screw to rotate, and then drive the push plate to slide back and forth along the slide groove. Then, the rack slides back and forth through the limit plate. During the sliding of the rack, the rack meshes with the first gear, thereby driving the rotating shaft and the second spray bar 4 to swing back and forth to spray solvent, thus improving the effect of use.

[0017] The parts of this device not described herein are the same as or can be implemented using existing technology. This utility model rotates and sets a second spray bar on both sides of the first spray bar. The second spray bar is located in the fan-shaped area away from the central axis. Both the first and second spray bars are equipped with nozzles. When the rotating body rotates, the second spray bar swings back and forth with the nozzles to spray the solvent. This can achieve a more uniform spraying of the solvent in all parts of the fan-shaped area, so that the oil and solvent in all parts of the same compartment can be in uniform contact, which can avoid oil waste and improve the use effect.

[0025] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figures 1-4A rotary extractor for tea oil production includes a fixed shaft 1, a rotating body 2 coaxially rotatable on the fixed shaft 1, and several fan-shaped material grids 201 within the rotating body 2. The rotating body 2 has a cylindrical structure of rotation. The fixed shaft 1 is located at the center of the rotating body 2. There are two to ten material grids 201, preferably six. The extractor also includes multiple first spray rods 3, each fixedly connected to one end of the fixed shaft 1 extending from the rotating body 2. There are two to ten first spray rods 3, preferably six, evenly distributed circumferentially. Furthermore, to provide a discharge station for each material grid 201, one of the six first spray rods 3 is removed. This position corresponds to the discharge station. The multiple first spray rods 3 rotate on both sides of their free ends. A second spray bar 4 is dynamically provided. Multiple nozzles 304 are fixedly installed at the bottom of both the first spray bar 3 and the second spray bar 4. The first spray bar 3 has two to ten nozzles 304, preferably nine, and they are evenly distributed along the radius of the rotating body 2. The second spray bar 4 has two to eight nozzles 304, preferably four. At this time, the first spray bar 3 and the second spray bars 4 on both sides form a trident structure and are located in the larger area of ​​the fan-shaped material grid 201, that is, in the position away from the central axis. When the rotating body 2 rotates, the second spray bar 4 carries the nozzles 304 and swings back and forth, so as to spray the solvent more evenly in all parts of the fan-shaped area, so that the contact reaction time between the oil and the solvent in the material grid 201 is relatively consistent, which can avoid the waste of oil and improve the use effect.

[0029] In use, a second spray bar 4 is rotated on both sides of the first spray bar 3. The second spray bar 4 is located in the fan-shaped area away from the central axis. Both the first spray bar 3 and the second spray bar 4 are equipped with nozzles 304. When the rotating body 2 rotates, the second spray bar 4, along with the nozzles 304, swings back and forth to spray the solvent. This can achieve a more uniform spraying of the solvent in all parts of the fan-shaped area, ensuring uniform contact between the oil and solvent in all parts of the same material compartment 201. This can avoid oil waste and improve the usage effect.

[0030] Reference Figures 2-4 Rotating seats 301 are fixedly installed on both sides of the first spray bar 3, and a rotating shaft is fixedly installed at one end of the second spray bar 4. The rotating shaft is rotatably connected to the rotating seats 301. In use, the rotating seats 301 are fixedly installed on both sides of the first spray bar 3, and the rotating shaft is fixedly installed on the second spray bar 4, so that the second spray bar 4 and the rotating seats 301 can be rotatably connected.

[0031] Reference Figures 2-4A push plate 5 is slidably mounted on the first spray bar 3. Limiting plates 501 are fixedly mounted on both sides of the push plate 5. A rack 502 is fixedly mounted on the end of the limiting plate 501 away from the push plate 5. A first gear 401 is fixedly mounted on the rotating shaft. The first gear 401 is slidably connected to the corresponding rack 502. The first spray bar 3 is provided with a driving part for driving the push plate 5 to slide. In use, the driving part drives the push plate 5 to slide back and forth. It can also drive the rack 502 to slide back and forth through the limiting plate 501. During the sliding process of the rack 502, the rack 502 meshes with the first gear 401, thereby driving the rotating shaft and the second spray bar 4 to swing back and forth to spray solvent, thereby improving the use effect.

[0032] Reference Figures 1-3 The drive unit can be a pneumatic cylinder, hydraulic cylinder, or electric telescopic cylinder to drive the push plate 5 to slide back and forth. Here, we prefer the reciprocating screw 6 as the drive unit. A groove 302 is provided at one end of the first spray bar 3 near the fixed shaft 1. The reciprocating screw 6 is rotatably set in the groove 302, and the end of the push plate 5 extending into the groove 302 cooperates with the reciprocating screw 6. When the reciprocating screw 6 rotates, it drives the push plate 5 to slide back and forth along the groove 302. That is, by driving the reciprocating screw 6 to rotate, the push plate 5 can be driven to slide back and forth along the groove 302. Then, the rack 502 slides back and forth through the limiting plate 501. During the sliding process of the rack 502, the rack 502 meshes with the first gear 401, thereby driving the rotating shaft and the second spray bar 4 to swing back and forth to spray solvent, thereby improving the use effect.

[0033] Reference Figure 1 and Figure 3 An end face gear 202 is coaxially fixed at the top of the rotating body 2, and a rotating shaft is fixed at one end of the reciprocating screw 6. A second gear 601 is fixed on the rotating shaft. The second gear 601 meshes with the end face gear 202. During use, as the rotating body 2 rotates, the meshing of the end face gear 202 and the second gear 601 drives the reciprocating screw 6 to rotate, which in turn drives the push plate 5 to slide back and forth along the slide groove 302. Then, the rack 502 slides back and forth through the limiting plate 501. During the sliding of the rack 502, the rack 502 meshes with the first gear 401, thereby driving the rotating shaft and the second spray bar 4 to swing back and forth to spray solvent, thus improving the effect of use.

[0034] Reference Figures 2-4Limiting grooves 303 are provided on both sides of the first spray bar 3, and the limiting plate 501 is slidably set in the limiting grooves 303. Moreover, the cross section of the limiting groove 303 is an inverted T-shaped structure. In use, by providing limiting grooves 303 on both sides of the first spray bar 3 and slidably setting the limiting plate 501 in the limiting grooves 303, not only can the limiting plate 501 and the rack 502 slide reliably, but the limiting plate 501 can also be prevented from falling off the first spray bar 3 and affecting normal use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
