Description

Technical Field

[0001] This utility model relates to the field of oil processing technology, and in particular to a raw material preheating device for a multi-cavity screw oil press. Background Technology

[0002] In the field of oil processing, the raw material pretreatment stage of the oil press is an indispensable and crucial step in the entire oil production process. The purpose of this stage is to treat oil crops through a series of physical or chemical methods to bring them to the optimal state for oil extraction, thereby significantly improving oil extraction efficiency and oil quality. Effective pretreatment can not only optimize the physical properties of raw materials, such as reducing viscosity and increasing oil fluidity, but also improve the chemical properties of raw materials, reduce the content of impurities and harmful substances, and ensure that the extracted oil has higher quality and better stability.

[0003] Traditional oil press preheating devices typically employ static heating, where the raw materials are placed in a heating container and heated by an external heat source. However, this static heating method has several drawbacks. First, the raw materials are prone to uneven heating during the heating process, resulting in some materials being overheated while others are underheated. Underheated materials, due to their insufficiently softened internal structure, are difficult to separate the oil during the subsequent oil pressing process, thus reducing pressing efficiency and potentially lowering oil yield. Second, static heating devices have low thermal energy utilization rates, with a significant amount of heat being lost to the surrounding environment through the container walls, wasting energy and increasing production costs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a raw material preheating device for a multi-cavity screw oil press.

[0005] This utility model is achieved using the following technical solution: a raw material preheating device for a multi-cavity screw oil press, comprising a raw material cylinder, a heating cover fixedly connected to the upper surface of the raw material cylinder, a heating fan fixedly installed on the inner wall of the heating cover by bolts, a heating wire fixedly connected to the inner wall of the heating cover, an auxiliary slider fixedly connected to the surface of the raw material cylinder, a base plate provided on the lower surface of the raw material cylinder, a support base fixedly connected to the upper surface of the base plate, a motor fixedly connected to the upper surface of the support base, an eccentric wheel fixedly connected to the output end of the motor, a transmission connecting rod rotatably connected to the surface of the eccentric wheel, and a movable sleeve rotatably connected to the surface of the transmission connecting rod.

[0006] The above technical solution uses a motor to drive an eccentric wheel, which in turn drives the raw material cylinder to reciprocate. This causes the raw material to tumble continuously inside the cylinder. Combined with the hot air generated by the heating fan, this ensures that all parts of the raw material receive heat evenly, thus achieving a highly efficient preheating effect. The reciprocating motion of the raw material cylinder increases the contact area and contact time between the raw material and the hot air, which greatly improves the preheating efficiency and shortens the preheating time compared to preheating in a static state.

[0007] As a further improvement to the above solution, the movable sleeve is fixedly connected to the surface of the raw material cylinder, and the upper surface of the raw material cylinder is provided with a heat inlet groove that is compatible with the heating cover.

[0008] As a further improvement to the above solution, both sides of the upper surface of the raw material cylinder are fixedly connected to limit groove plates, and the surface of the limit groove plates is provided with sliding grooves.

[0009] As a further improvement to the above solution, the auxiliary slider is slidably connected to the inside of the groove, and there are two auxiliary sliders, which are respectively fixedly connected to both sides of the outer surface of the raw material cylinder.

[0010] With the above technical solution, two auxiliary sliders are fixed on both sides of the raw material cylinder, providing more stable support for the raw material cylinder and enabling it to move more smoothly along the predetermined straight line during reciprocating motion.

[0011] As a further improvement to the above solution, a feeding cover plate is hinged to the surface of the raw material cylinder, and a handle groove is provided on the surface of the feeding cover plate.

[0012] As a further improvement to the above solution, a second motor is fixedly connected to the lower surface of the raw material cylinder, and a transmission rod is fixedly connected to the output end of the second motor.

[0013] As a further improvement to the above solution, several mixing blades are fixedly connected to the surface of the transmission rod, and the mixing blades are rotatably connected to the inside of the raw material cylinder.

[0014] Through the above technical solution, the rotation of the mixing blade can further agitate the raw materials inside the raw material cylinder, making the raw materials more uniform during the preheating process.

[0015] As a further improvement to the above solution, the surface of the base plate is provided with a clearance groove, and the second motor is slidably connected inside the clearance groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a motor to drive an eccentric wheel to rotate. Utilizing the structural characteristics of the eccentric wheel, the transmission connecting rod drives the movable sleeve and the raw material cylinder in a reciprocating linear motion. The auxiliary slider and slide groove ensure the linear movement of the raw material cylinder, causing the raw material to continuously tumble inside. Combined with the hot air generated by the heating fan, this ensures that all parts of the raw material are heated evenly, effectively avoiding the problem of insufficient localized preheating. Simultaneously, during the reciprocating linear motion of the raw material cylinder, a second motor starts, and the transmission rod rotates, driving the mixing blades to rotate inside the raw material cylinder. The rotation of the mixing blades further agitates the raw material inside the cylinder, allowing it to receive heat more evenly during preheating, further improving the preheating effect.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Example

[0021] Please combine Figure 1-4This embodiment of a multi-cavity screw oil press raw material preheating device includes a raw material cylinder 1. A heating cover 2 is fixedly connected to the upper surface of the raw material cylinder 1. A heating fan 3 is fixedly installed on the inner wall of the heating cover 2 by bolts. A heating wire 4 is fixedly connected to the inner wall of the heating cover 2. An auxiliary slider 5 is fixedly connected to the surface of the raw material cylinder 1. A base plate 6 is provided on the lower surface of the raw material cylinder 1. A support base 7 is fixedly connected to the upper surface of the base plate 6. A motor 8 is fixedly connected to the upper surface of the support base 7. An eccentric wheel 9 is fixedly connected to the output end of the motor 8. A transmission connecting rod 10 is rotatably connected to the surface of the eccentric wheel 9. A movable sleeve 11 is rotatably connected to the surface of the transmission connecting rod 10. The motor 8 serves as a power source, and its output end is connected to the eccentric wheel 9. When the motor 8 starts, the eccentric wheel 9 rotates around its central axis. Due to the structural characteristics of the eccentric wheel 9, its edge is not concentric with the central axis. During the rotation, the distance from any point on the surface of the eccentric wheel 9 to the central axis will change continuously. One end of the transmission link 10 is movably connected to the surface of the eccentric wheel 9, and the other end is connected to the movable sleeve 11. When the eccentric wheel 9 rotates, the transmission link 10 will drive the movable sleeve 11 to reciprocate linearly along a direction perpendicular to the rotation axis of the eccentric wheel 9. The movable sleeve 11 is fixedly connected to the surface of the raw material cylinder 1, so that the raw material cylinder 1 also reciprocates linearly. An auxiliary slider 5 is also fixedly connected to the surface of the raw material cylinder 1. The auxiliary slider 5 can move linearly on the base plate 6 to ensure that the reciprocating motion of the raw material cylinder 1 is more stable. After the heating fan 3 is started, the heating wire 4 is energized to generate heat. The air generated by the heating fan 3 will heat the air through the heating wire 4 to form hot air. The hot air preheats the raw material inside the raw material cylinder 1, so that the raw material can be heated evenly during the movement.

[0022] The movable sleeve 11 is fixedly connected to the surface of the raw material cylinder 1, and the upper surface of the raw material cylinder 1 is provided with a heat inlet groove that is compatible with the heating cover 2.

[0023] Limiting groove plates 12 are fixedly connected to both sides of the upper surface of the raw material cylinder 1. The surface of the limiting groove plate 12 is provided with a sliding groove 13. The limiting groove plate 12 provides a stable sliding track for the auxiliary slider 5, ensuring that the raw material cylinder 1 moves along a predetermined straight direction during reciprocating motion without deviation or shaking.

[0024] The auxiliary slider 5 is slidably connected inside the slide groove 13. Two auxiliary sliders 5 are provided, each fixedly connected to one side of the outer surface of the raw material cylinder 1. The two auxiliary sliders 5 provide lateral support and guidance to the raw material cylinder 1 during reciprocating motion, further enhancing its stability. The sliding of the auxiliary sliders 5 inside the slide groove 13 allows the raw material cylinder 1 to move smoothly in a straight line along the direction of the slide groove 13. Simultaneously, the auxiliary sliders 5 can withstand a certain lateral force, preventing the raw material cylinder 1 from tilting or deviating during movement.

[0025] A feeding cover plate 14 is hinged to the surface of the raw material cylinder 1. The surface of the feeding cover plate 14 is provided with a handle groove. The design of the feeding cover plate 14 makes it easy to add raw materials into the raw material cylinder 1.

[0026] A second motor 16 is fixedly connected to the lower surface of the raw material cylinder 1, and a transmission rod 17 is fixedly connected to the output end of the second motor 16.

[0027] Several mixing blades 18 are fixedly connected to the surface of the transmission rod 17. The mixing blades 18 are rotatably connected to the inside of the raw material cylinder 1. When the motor 16 starts, the transmission rod 17 rotates, driving the mixing blades 18 to rotate inside the raw material cylinder 1. The rotation of the mixing blades 18 can further agitate the raw material inside the raw material cylinder 1, making the raw material more uniform during the preheating process.

[0028] The surface of the base plate 6 is provided with a clearance groove 15, and the motor 2 16 is slidably connected to the inside of the clearance groove 15.

[0029] The implementation principle of the raw material preheating device for a multi-cavity screw oil press in this embodiment is as follows: First, the operator opens the feeding cover 14 and adds the raw material into the raw material cylinder 1. Then, the feeding cover 14 is closed, and the motor 8 is started. The eccentric wheel 9 rotates around its central axis. Since the edge of the eccentric wheel 9 is not concentric with the central axis, the distance from any point on its surface to the central axis changes continuously during rotation. One end of the transmission connecting rod 10 is movably connected to the surface of the eccentric wheel 9, and the other end is connected to the movable sleeve 11. The rotation of the eccentric wheel 9 drives the movable sleeve 11 to reciprocate linearly along a direction perpendicular to the rotation axis of the eccentric wheel 9 via the transmission connecting rod 10. The movable sleeve 11 is fixedly connected to the raw material cylinder. The surface of the raw material cylinder 1 is fixedly connected to the surface of the raw material cylinder 1, so that the raw material cylinder 1 also reciprocates in a linear motion. Two auxiliary sliders 5 are also fixedly connected to the surface of the raw material cylinder 1. These two auxiliary sliders 5 are located on both sides of the outer surface of the raw material cylinder 1 and are slidably connected to the inside of the groove 13 on the surface of the limiting groove plate 12. The limiting groove plate 12 provides a stable sliding track for the auxiliary sliders 5, ensuring that the raw material cylinder 1 moves along the predetermined linear direction during the reciprocating motion without deviation or shaking. The sliding of the auxiliary sliders 5 inside the groove 13 not only enables the raw material cylinder 1 to move smoothly in a linear motion, but also withstands a certain lateral force, preventing the raw material cylinder 1 from tilting or deviating during the motion, further enhancing the stability of the motion.

[0030] Then, the heating fan 3 is started, and the heating wire 4 is energized to generate heat. The air generated by the heating fan 3 is heated by the heating wire 4 to form hot air. The hot air enters the inside of the raw material cylinder 1 through the heating groove on the upper surface of the raw material cylinder 1 that is compatible with the heating cover 2, and preheats the raw material. The reciprocating linear motion of the raw material cylinder 1 causes the raw material to tumble continuously inside the cylinder. Combined with the blowing of hot air, this ensures that all parts of the raw material can receive heat evenly, achieving a highly efficient preheating effect.

[0031] Meanwhile, during the reciprocating linear motion of the raw material cylinder 1, the second motor 16 starts, the transmission rod 17 rotates, and the mixing blade 18 rotates inside the raw material cylinder 1. The rotation of the mixing blade 18 can further agitate the raw material inside the raw material cylinder 1, so that the raw material can receive heat more evenly during the preheating process, and further improve the preheating effect.

[0032] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
