Description

Technical Field

[0001] This invention relates to the field of cottonseed oil extraction technology, and in particular to a cottonseed pretreatment oil extraction device. Background Technology

[0002] Before pressing cottonseed into oil, it needs to undergo a pretreatment process of wetting and steaming to allow the cottonseed to absorb water and swell and burst the glands, and to solidify the free gossypol with the protein. This is the core process to ensure the quality of crude oil and reduce the gossypol content in the oil cake. At present, traditional cottonseed pretreatment equipment is mostly of a split structure, with the wetting and steaming processes operating independently. The process connection is cumbersome, the production continuity is poor, and there are many technical defects. Traditional humidification chambers often employ a fixed chamber structure, relying solely on a single stirring mechanism to agitate the material. This leads to issues such as bridging, sticking to the walls, and clumping. Dead zones in temperature and humidity exist within the chamber, resulting in uneven wetting of cottonseeds, varying degrees of dryness and moisture, and significant differences in the expansion of pigment glands. This directly impacts subsequent phenol removal. Furthermore, traditional steaming equipment often involves static accumulation or simple agitation of materials, resulting in poor steam penetration and uneven contact between the material and saturated steam. This can lead to localized under-steaming, incomplete phenol solidification, or localized over-steaming causing secondary phenol release, resulting in excessive color in crude oil and unusable cake feed. Additionally, existing equipment often uses independent electrical controls for feeding, discharging, and chamber sealing, leading to cumbersome structures, high failure rates, and the risk of air leakage during steaming, causing phenol oxidation and deterioration. Furthermore, split-type equipment occupies a large area, consumes high energy, and cannot achieve process linkage and adaptation, making it difficult to accurately match the specific process time and environmental requirements for cottonseed wetting and steaming. This results in poor pretreatment stability and low product qualification rates. Summary of the Invention

Each of the rotating cylinders has a number of evenly distributed protrusions 1 and 2 integrally formed on its sidewall, and both protrusions 1 and 2 abut against the sub-disc. The positions of each of the two protrusions on the side wall of the rotating drum are different.

[0008] Preferably, a driver is fixedly installed on the top of the cavity; The rotating component is slidably mounted on the outside of the output shaft of the driver, and a spring is provided between the rotating component and the output shaft of the driver.

Through the fixing and movement of the magnetically controlled top cover, it achieves automated operation of intermittent, precise material feeding and automatic discharge. The drum operates in a completely sealed environment, maintaining a stable working environment within the steaming chamber and preventing cold air intrusion that could lead to gossypol oxidation. Simultaneously, the rotation of the drum triggers the partition to reciprocate, achieving material agitation without the need for an additional drive mechanism. This simplifies the equipment structure, reduces energy consumption, effectively improves the pre-treatment quality and processing efficiency of cottonseeds, and reduces oil refining losses. In summary, this invention, through the combination of a layered cavity structure and a multi-linkage mechanical mechanism, achieves integrated continuous pretreatment of cottonseed wetting and steaming, effectively solving the problems of uneven processing, easy material clumping, and poor process connection in traditional equipment.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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. Therefore, they should not be construed as limitations on this invention.

[0018] The cottonseed pretreatment device in the related technology has at least the following problems when in use: First, traditional humidification chambers mostly use a fixed chamber structure, relying solely on a single stirring structure to turn the material. This makes the material prone to bridging, sticking to the walls, and clumping. There are dead zones of temperature and humidity inside the chamber, resulting in uneven wetting of cottonseeds and significant differences in the degree of expansion of pigment glands, which directly affects the subsequent phenol removal effect.

[0019] Secondly, in traditional steaming equipment, the material is left to stand still or simply turned over, resulting in poor steam penetration and uneven contact between the material and saturated steam. This can easily lead to problems such as insufficient local steaming, incomplete curing of gossypol, or excessive local steaming that causes secondary release of gossypol, resulting in excessive color of crude oil and unusable cake meal.

[0020] Furthermore, existing equipment often uses independent electrical control for feeding, discharging, and cavity sealing, resulting in a cumbersome structure, high failure rate, and easy air leakage into the cavity during the steaming process, which can lead to the oxidation and deterioration of gossypol.

[0021] Finally, split-type equipment occupies a large area, consumes a lot of energy, and cannot achieve process linkage and adaptation. It is difficult to accurately match the exclusive process time and environmental requirements for cottonseed wetting and steaming, resulting in poor pretreatment stability and low product qualification rate.

[0022] In view of the above-mentioned technical problems, this application provides a cottonseed pretreatment oil pressing device to solve the problems mentioned above.

[0023] Reference Figures 1-11 As shown, a cottonseed pretreatment oil pressing device includes a cavity 1 and a partition 23, with the partition 23 movably installed inside the cavity 1. Above the partition 23 is a wetting chamber, and below it is a steaming chamber. A basic assembly, located inside the cavity 1, includes an inlet end 11 and an outlet end 12. The inlet end 11 is located at the top of the cavity 1, and the outlet end 12 is located at the bottom of the cavity 1. Both the inlet end 11 and the outlet end 12 are equipped with sealing caps. A wetting assembly, located inside the cavity 1 and above the partition 23, includes a rotating component 21. The rotating component 21 is rotatably installed inside the cavity 1, and several evenly distributed levers 214 are fixedly installed on its side wall. A blocking assembly, located inside the cavity 1, includes a baffle 22 and a pull rod 224. The side wall of the partition 23 is provided with a discharge pipe 233, and the baffle 22 is slidably installed inside the discharge pipe 233. 4. Sliding installation at the bottom inside the cavity 1; Steaming assembly, set inside the cavity 1 and located below the partition plate 23, including several rotating cylinders 24; Several rotating cylinders 24 are evenly distributed in a circular shape inside the cavity 1 and are rotatably installed inside the cavity 1. The rotating cylinders 24 are conical. Each rotating cylinder 24 has an integrally formed feed pipe 241 on its side wall. The discharge pipe 233 and the discharge end 12 are all corresponding to the feed pipe 241. The total capacity of the several rotating cylinders 24 filled with cottonseed is equal to twice the capacity of the cottonseed processed in a single humidification chamber. This makes the rotating cylinders 24 evenly distributed in two groups along the circumference. The total volume of the two groups of rotating cylinders 24 is equal to the single feeding capacity of the humidification chamber. This allows the cottonseed in the other group of rotating cylinders 24 to be filled and continuously undergo steaming reaction simultaneously when the humidification process is completed and the material in the cavity is discharged into an empty rotating cylinder 24. The two groups of rotating cylinders 24 take turns performing the feeding and steaming processes in turn without interfering with each other. During the pretreatment of cottonseed, the operator opens the sealing cover of the feed end 11 and puts the cottonseed into the feed end 11, causing the cottonseed to fall above the partition plate 23 (wetting chamber). This causes the rotating part 21 to rotate clockwise and stirs the cottonseed through the lever 214, ensuring that the cottonseed is evenly wetted. After wetting is completed, the baffle plate 22 is opened. At this time, the discharge pipe 233 and the feed pipe 241 of one of the rotating drums 24 are aligned. The rotating part 21 rotates in reverse and stirs the cottonseed through the lever 214. Cottonseeds are pushed into the discharge pipe 233, allowing raw cottonseeds to enter the rotating drum 24. After the raw cottonseeds are filled into the rotating drum 24, the baffle 22 is closed, and the rotating drum 24 revolves around the inside of the cavity 1 while rotating on its own axis to ensure that the raw cottonseeds and steam are in uniform contact. After the steaming is completed, the feed pipe 241 of the rotating drum 24 corresponds to the discharge end 12. At this time, the drive rod 224 is activated, causing the raw cottonseeds inside the rotating drum 24 to be discharged into the discharge end 12.

[0024] like Figure 2 , Figure 5 , Figure 10 and Figure 11 As shown, a second driver 313 is fixedly installed at the bottom of cavity 1; the second driver 313 can be a servo motor, mainly used to drive the rotating shaft 314 to rotate forward and reverse, or it can be an electric motor or other driving element that can drive the rotating shaft 314 to rotate forward and reverse; the output end of the second driver 313 is fixedly connected to the rotating shaft 314, and a support cylinder 31 is rotatably sleeved on the outer side of the rotating shaft 314, and a ratchet 311 is provided between the support cylinder 31 and the rotating shaft 314; each rotating cylinder 24 is rotatably connected to the side wall of the support cylinder 31. During the steaming process, the second driver 313 drives the rotating shaft 314 to rotate forward. The rotating shaft 314 drives the support cylinder 31 to rotate forward through the ratchet 311, so that the support cylinder 31 drives the rotating cylinder 24 to revolve inside the cavity 1. This ensures that the cotton seeds inside the rotating cylinder 24 are in uniform contact with the steam inside the steaming cavity, while optimizing the uniformity of the steam distribution inside the steaming cavity.

[0025] like Figure 2 , Figure 4 and Figure 10 As shown, a gear ring 125 is fixedly installed on the inner wall of the cavity 1; a gear 245 is fixedly installed on the side wall of the rotating drum 24, and the gear 245 meshes with the gear ring 125; the top of the gear ring 125 is provided with two flat grooves 126, one of which is located below the discharge pipe 233, and the other is located above the discharge end 12; the gear 245 is slidably inserted into the interior of the flat groove 126; the side wall of the rotating drum 24 is provided with several evenly distributed vent holes; During the revolution of the rotating drum 24, the gear ring 125 drives the gear 245 to rotate, and the gear 245 drives the rotating drum 24 to rotate, causing the cottonseed to tumble inside the rotating drum 24, further improving the uniformity of contact between the cottonseed and the steam.

[0026] like Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 10 As shown, a slip ring 237 is slidably installed inside the cavity 1; a partition 23 is movably installed inside the slip ring 237, and both the inner side of the slip ring 237 and the outer side of the partition 23 are spherical; a support ring 124 is provided inside the cavity 1, and the slip ring 237 is in its lowest position when the bottom of the slip ring 237 and the top of the support ring 124 abut against each other; a secondary disk 235 is integrally formed at the bottom of the partition 23, and a flexible ring 236 is fixedly sleeved on the outer side of the secondary disk 235, and the outer side of the flexible ring 236 is fixedly connected to the inner wall of the cavity 1; several evenly distributed protrusions 246 and 247 are integrally formed on the side wall of each rotating cylinder 24, and both protrusions 246 and 247 abut against the secondary disk 235; the positions of protrusions 246 and 247 on the side wall of each rotating cylinder 24 are different; During the revolution of the rotating drum 24, the protrusions 246 and 247 on the side wall of the rotating drum 24 continuously abut against the auxiliary disk 235, causing the auxiliary disk 235 to drive the partition disk 23 to continuously shake inside the cavity 1. This causes the partition disk 23 to continuously lift up and turn over the cotton seeds above, ensuring that both the upper and lower layers of cotton seeds can come into contact with the moist moisture, thus improving the moisturizing effect of the cotton seeds. When the auxiliary disk 235 returns to its original position, the circumferential tension of the flexible ring 236 is equal, so that the partition disk 23 remains in a horizontal state.

[0027] like Figure 2 and Figures 5-8 As shown, a driver 211 is fixedly installed on the top of the cavity 1; a rotating component 21 is slidably fitted on the outside of the output shaft of the driver 211, and a spring 213 is provided between the rotating component 21 and the output shaft of the driver 211; the driver 211 can be a servo motor, mainly used to drive the rotating component 21 to rotate forward and reverse, or it can be an electric motor or other drive element that can drive the rotating component 21 to rotate forward and reverse; a ball head 212 is integrally formed on the bottom of the rotating component 21; a fixed plate 231 is fixedly installed on the top of the partition 23, and a ball groove 232 is integrally formed at the center of the fixed plate 231, with the ball head 212 movably installed inside the ball groove 232; After multiple protrusions 246 simultaneously abut and lift the sub-disc 235, the sub-disc 235 drives the partition 23 and slip ring 237 to move upward. The partition 23 drives the rotating component 21 to move upward, so that the rotating component 21 disturbs the cotton seeds adhering to the inner wall of the cavity 1 through the lever 214, preventing the cotton seeds from always adhering to the inner wall of the cavity 1. During the shaking of the partition 23, the rotating component 21, through the ball head 212 and ball groove 232, cooperates with the shaking of the partition 23, so that the lever 214 can stir the cotton seeds in multiple positions, increase the range of cotton seed disturbance by the lever 214, and enhance the cotton seed wetting effect.

[0028] like Figure 8 , Figure 9 and Figure 11 As shown, the top of the partition 23 has a movable groove 238, and the baffle 22 is slidably installed inside the movable groove 238; the bottom of the baffle 22 is integrally formed with a support rod 221; the bottom of the partition 23 is integrally formed with a support plate 234, and a second spring 222 is provided between the support rod 221 and the support plate 234; the bottom of the support rod 221 is provided with a crossbar 226, and a rack 223 is fixedly installed on the side wall of the crossbar 226; a second gear 315 is rotatably sleeved on the top of the rotating shaft 314, and the rack 223 on the side wall of the crossbar 226 meshes with the second gear 315, which is an intermittent gear; a second ratchet 312 is provided between the second gear 315 and the rotating shaft 314, and the locking directions of the first ratchet 311 and the second ratchet 312 are opposite. After the cottonseeds are moistened, the second actuator 313 drives the rotating drum 24 to correspond with the discharge pipe 233. At this time, the second actuator 313 drives the rotating shaft 314 to reverse. The rotating shaft 314 drives the second gear 315 to rotate through the second ratchet 312. The second gear 315 drives the baffle 22 to move towards the rotating shaft 314 through the rack 223 on the side wall of the crossbar 226. At this time, the discharge pipe 233 opens, the support rod 221 squeezes the second spring 222, and the second actuator 313 closes. After the cottonseeds are transferred to the inside of the rotating drum 24 through the discharge pipe 233, the second actuator 313 drives the rotating shaft 314 to reverse again. The second gear 315 separates from the rack 223 on the side wall of the crossbar 226, the second spring 222 is released, the baffle 22 is reset, and the discharge pipe 233 is closed.

[0029] like Figure 3 and Figures 9-11 As shown, a top cover 242 is slidably installed on the top of the feed pipe 241; several evenly distributed magnetic strips 243 are fixedly installed on the side wall of the top cover 242 and the top of the feed pipe 241, with the magnetic strips 243 on the side wall of the top cover 242 and the magnetic strips 243 on the top of the feed pipe 241 corresponding one-to-one; magnetic strips 225 are provided on the side walls of the crossbar 226 and the pull rod 224; magnetic strips 244 are fixedly installed on the side wall of the top cover 242, with the magnetic strips 225 and the magnetic strips 244 corresponding to each other; During the revolution and rotation of the rotating drum 24, the top cover 242 is fixed to the top of the feed pipe 241 by magnetic strip 243. When the rotating drum 24 aligns with the discharge pipe 233 or the discharge end 12, magnetic strip 225 and magnetic strip 244 align (magnetic strip 243 on the side wall of the top cover 242 and magnetic strip 243 on the top of the feed pipe 241 are still in a corresponding state). At this time, the drive bar 226 or pull rod 224 moves, and the drive bar 226 or pull rod 224 will abut against the top cover 242, causing the top cover 242 to... Separated from the discharge pipe 233, the crossbar 226 or pull rod 224 fixes the top cover 242 to the side wall through magnetic strip 1 225 and magnetic strip 3 244. After the drive crossbar 226 or pull rod 224 is reset, the top cover 242 is reset (the magnetic strip 243 on the side wall of the top cover 242 and the magnetic strip 243 on the top of the feed pipe 241 are in the corresponding state, and the magnetic strip 1 225 and magnetic strip 3 244 are also in the corresponding state). When the rotating drum 24 revolves and rotates again, the magnetic strip 1 225 and magnetic strip 3 244 are separated.

[0030] like Figure 2 , Figure 9 and Figure 11 As shown, a driver 316 is fixedly installed at the bottom of cavity 1, and a gear 317 is fixedly connected to the output end of the driver 316. The driver 316 can be a servo motor, mainly used to drive the gear 317 to rotate, or it can be an electric motor or other drive element that can drive the gear 317 to rotate. A gear 4 318 is rotatably installed at the bottom of cavity 1, and the gear 4 318 meshes with the gear 317. A rack 223 is fixedly installed on the side wall of the pull rod 224; the gear 4 318 meshes with the rack 223. After the cottonseed is steamed, the second driver 313 drives the rotating drum 24 to correspond to the discharge end 12. At this time, the second driver 313 is closed, the third driver 316 is started and drives the third gear 317 to rotate forward. The third gear 317 meshes with the fourth gear 318, and the fourth gear 318 meshes with the rack 223 on the side wall of the pull rod 224, so that the pull rod 224 drives the corresponding top cover 242 to move towards the rotating shaft 314. The feed pipe 241 on the side wall of the corresponding rotating drum 24 is opened, and the cottonseed inside the corresponding rotating drum 24 is discharged to the discharge end 12 through the feed pipe 241. After the cottonseed inside the rotating drum 24 is discharged, the third driver 316 is started and drives the third gear 317 to rotate in reverse. The pull rod 224 drives the top cover 242 to reset, and the feed pipe 241 on the side wall of the corresponding rotating drum 24 is closed.

[0031] like Figure 1 , Figure 2 and Figure 4As shown, a first nozzle 121 and a second nozzle 122 are fixedly installed inside the cavity 1. The first nozzle 121 is located above the lever 214 and is fixedly connected to the inner wall of the cavity 1. The bottom of the first nozzle 121 has a spray hole. The second nozzle 122 is located below the rotating drum 24 and is fixedly connected to the inner wall of the cavity 1. The top of the second nozzle 122 has a spray hole. The first nozzle 121 is fixedly connected to an external softened water supply device and is used to spray atomized soft water into the humidification chamber to humidify the cottonseed. The second nozzle 122 is fixedly connected to an external saturated steam supply device and is used to deliver high-temperature saturated steam into the steaming chamber to provide a constant steam medium for the cottonseed steaming reaction. A temporary storage chamber 123 is opened at the bottom of the cavity 1. The temporary storage chamber 123 corresponds to the feed pipe 241, and the discharge end 12 is located at the bottom of the temporary storage chamber 123. The cottonseed is discharged from the feed pipe 241 on the side wall of the rotating drum 24 into the interior of the temporary storage chamber 123. The staff can open the sealing cover inside the discharge end 12 to discharge the cottonseed inside the temporary storage chamber 123. When the cottonseed is discharged through the discharge end 12 after the steaming is completed, the steam inside the steaming chamber is discharged outward through the discharge end 12 to prevent cold air from entering the steaming chamber.

[0032] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
