Description

Technical Field

[0001] This utility model relates to the field of oil pressing equipment, specifically a residue cleaning device for tea seed oil pressing. Background Technology

[0002] The core equipment of a tea seed oil pressing device includes three major stages: pretreatment, pressing, and refining. The pretreatment stage requires the use of equipment such as shellers, crushers, and steaming pans to ensure that the tea seeds are shelled, crushed, and that the moisture and temperature are adjusted to increase the oil yield. The pressing stage is mainly divided into screw oil presses and hydraulic oil presses. Screw oil presses use screws to squeeze the tea seeds, while hydraulic oil presses use a hydraulic system to press the seeds in stages.

[0003] Current tea seed oil pressing devices compress tea seed raw materials to obtain internal oil. However, there is a problem in actual use: after pressing, the tea seeds become a cake-like structure, which is difficult to remove from the inside of the pressing cylinder. In view of this, the inventors urgently need to design an oil pressing device that can quickly remove residue, so as to facilitate the rapid removal and recycling of waste residue. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a residue removal device for tea seed oil extraction, so as to solve the technical problem that the cake residue is difficult to remove after tea seed oil extraction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slag-cleaning device for tea seed oil extraction, comprising a support frame, a hydraulic rod installed above the support frame, a pressing plate installed at the telescopic end of the hydraulic rod, and a slag-cleaning mechanism installed on the pressing plate;

[0006] The slag removal mechanism includes a movable plate, on which several telescopic rods are fixedly installed. The top of each telescopic rod passes through a through hole through the extrusion plate and is fitted with a traction ring. A lifting component is installed between the traction ring and the extrusion plate.

[0007] By adopting the above technical solution, it can work in coordination with the extrusion action driven by the hydraulic rod. At the same time, when the hydraulic rod drives the extrusion plate to complete the pressing process and retract, the slag cleaning mechanism can be activated synchronously and act independently. The lifting component pushes the traction ring and transmits power through the telescopic rod that passes through the extrusion plate, forcibly driving the movable plate located inside the oil pressing cylinder to move.

[0008] Furthermore, several of the telescopic rods are arranged in a circular pattern at equal intervals, the telescopic rods are cylindrical in shape, and the telescopic rods are sealed and sleeved with the through holes.

[0009] By adopting the above technical solution, this symmetrical force-bearing mode effectively prevents the risk of the movable plate tilting or jamming during movement, ensuring the stability and reliability of the slag cleaning action, while extending the service life of the movable plate and the inner wall of the oil pressing cylinder. The cylindrical structure of the telescopic rod provides excellent bending stiffness and guiding accuracy, further enhancing the stability of the mechanism's movement.

[0010] Furthermore, several lifting components are provided, which simultaneously lift the traction ring, with the telescopic end of the lifting component abutting against the bottom surface of the traction ring.

[0011] By adopting the above technical solution, the synchronous drive of multiple points can ensure that the traction ring always moves upward in a horizontal state, avoiding the phenomenon of tilting, uneven loading or even jamming that may be caused by single-point force, which significantly improves the reliability and success rate of slag removal operation, especially for demolding thick oil cakes produced by large-diameter or high-viscosity materials.

[0012] Furthermore, a receiving plate is fixedly installed in the middle of the support frame, and an oil pressing cylinder is fixedly installed at the center of the receiving plate. Several oil leakage holes are evenly opened on the outer surface of the oil pressing cylinder for oil leakage.

[0013] By adopting the above technical solution, the core basic structure of the entire oil pressing and collection process is formed. The oil pressing cylinder is stably supported and positioned in the center of the receiving plate, precisely aligned with the upper extrusion plate and movable plate. This layout lays a solid physical foundation for efficient pressing. Several evenly distributed oil leakage holes on the outer surface of the oil pressing cylinder are key channels for oil penetration and discharge. These evenly distributed oil leakage holes provide a sufficient and least resistant outflow path for the pressed oil.

[0014] Furthermore, the extrusion plate, the movable plate, and the oil pressing cylinder are arranged coaxially and are adapted to the inner diameter of the oil pressing cylinder.

[0015] By adopting the above technical solution, this is the geometric basis for ensuring a uniform and effective pressing process and smooth slag removal. Strict coaxiality means that when the pressing plate is pressed down, its force can be transmitted vertically and evenly to the moving plate and the raw material layer between them. This avoids problems such as uneven force on the raw material, insufficient or excessive local compression, and obstruction of the oil seepage path caused by eccentric pressure. This ensures that the entire raw material cake is subjected to a balanced hydraulic force, and the oil pressing efficiency and oil uniformity are maximized.

[0016] Furthermore, an oil outlet pipe is connected to the lower side of one side of the receiving plate, and the oil outlet pipe is connected to an external receiving device.

[0017] By adopting the above technical solution, a simple and functionally clear direct discharge channel is provided for the pressed oil collected in the receiving pan. After the oil completes its initial flow in the receiving pan, it can be continuously and smoothly guided to the outside through the directly connected oil outlet pipe without going through complex internal pipelines or turning structures. This single-point, short-path connection method minimizes the flow resistance and the risk of oil retention inside the equipment, significantly improves the efficiency of oil discharge, and can promptly remove the pressed oil from the system, avoiding its long-term exposure to high temperature or oxygen environment, which would affect its quality.

[0018] Furthermore, the telescopic rod passes through the traction ring and is fixedly connected by a fastening nut, which is used to adjust the initial longitudinal installation position of the traction ring.

[0019] By adopting the above technical solution, this through connection forms a rigid physical connection between the telescopic rod and the traction ring. Whether it is subjected to downward compression and reset force or to the huge upward force applied by the lifting component, the fastening nut can reliably lock and fix the traction ring in the designed position of the telescopic rod, effectively preventing slippage, loosening or rotation during the force process.

[0020] In summary, the present invention has the following main advantages:

[0021] 1. This utility model integrates the slag removal mechanism into the hydraulically driven extrusion plate to achieve coordinated pressing and slag removal actions: when the hydraulic rod moves downward, the extrusion plate pressurizes the tea seeds in the oil pressing cylinder to produce oil, and the oil flows into the receiving plate through the oil leakage hole in the cylinder wall and is discharged through the oil outlet pipe; when the hydraulic rod returns, the lifting component automatically pushes the traction ring, and the linkage telescopic rod drives the movable plate to rise, forcing the cake residue to detach from the inner wall of the oil pressing cylinder, thus solving the problem of residue adhesion and blockage.

[0022] 2. This utility model adjusts the position of the traction ring on the telescopic rod by tightening the nut, adapting to the cleaning needs of residues of different thicknesses, and realizing continuous automated operation of oil pressing and residue cleaning. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] In this embodiment:

[0030] Tea seed oil extraction uses a residue removal device, such as... Figure 1-4 As shown, it includes a support frame 1, a hydraulic rod 2 is installed above the support frame 1, an extrusion plate 3 is installed at the telescopic end of the hydraulic rod 2, and a slag removal mechanism 7 is installed on the extrusion plate 3.

[0031] The slag removal mechanism 7 includes a movable plate 701, on which several telescopic rods 702 are fixedly mounted. The top of each telescopic rod 702 passes through a through hole 706 through the extrusion plate 3 and is fitted with a traction ring 703. A lifting member 705 is installed between the traction ring 703 and the extrusion plate 3, enabling it to work in coordination with the extrusion action driven by the hydraulic rod 2. Simultaneously, when the hydraulic rod 2 drives the extrusion plate 3 to complete the pressing process and retract, the slag removal mechanism 7 can be activated synchronously and act independently. The lifting member 705 pushes the traction ring 703 and, via... The telescopic rod 702 that runs through the extrusion plate 3 transmits power, forcibly driving the movable plate 701 located inside the oil pressing cylinder 4 to move. This power transmission method effectively integrates the slag removal action into the main oil pressing cycle. During the process of the extrusion plate 3 lifting and separating from the material, it can actively push the cake-shaped residue formed by pressing upwards away from the inner wall of the oil pressing cylinder 4, greatly shortening the process switching time and solving the problem of residue sticking together after pressing in traditional devices and requiring manual handling. It fundamentally realizes efficient and automated residue discharge and improves the continuous operation capability of the equipment.

[0032] See Figure 3 , Figure 4Several telescopic rods 702 are arranged in a ring at equal intervals. The telescopic rods 702 are cylindrical in shape and are sealed to the through holes 706. This symmetrical force-bearing mode effectively prevents the risk of the movable plate 701 from tilting or jamming during movement, ensuring the stability and reliability of the slag removal action. At the same time, it extends the service life of the movable plate 701 and the inner wall of the oil pressing cylinder 4. The cylindrical structure of the telescopic rods 702 provides excellent bending stiffness and guiding accuracy, further enhancing the stability of the mechanism's movement. Meanwhile, the sealed connection between the telescopic rods 702 and the through holes 706 on the pressing plate 3 plays a crucial blocking role. On the one hand, it ensures that the telescopic rods 702 can slide smoothly in the through holes 706 and bear radial loads, meeting the guiding requirements for the lifting and lowering of the movable plate 701. On the other hand, and most importantly, it establishes an effective oil sealing barrier.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 Several lifting components 705 are provided, which simultaneously lift the traction ring 703. The telescopic end of the lifting component 705 abuts against the bottom surface of the traction ring 703. The synchronous drive of multiple points ensures that the traction ring 703 always maintains a horizontal state and moves upward, avoiding the phenomenon of tilting, uneven loading or even jamming that may be caused by single-point force. This significantly improves the reliability and success rate of slag removal operation, which is especially critical for demolding thick oil cakes produced by large-diameter or high-viscosity materials. At the same time, it is clearly stipulated that the telescopic end of the lifting component 705 directly abuts against the bottom surface of the traction ring 703, which greatly simplifies the power transmission chain.

[0034] See Figure 1 , Figure 2 , Figure 3 A receiving plate 5 is fixedly installed in the middle of the support frame 1, and an oil pressing cylinder 4 is fixedly installed at the center of the receiving plate 5. Several oil leakage holes are evenly distributed on the outer surface of the oil pressing cylinder 4 for oil seepage, forming the core basic structure of the entire oil pressing and collection process. The oil pressing cylinder 4 is stably supported and positioned in the center of the receiving plate 5, precisely aligned with the upper extrusion plate 3 and movable plate 701. This layout lays a solid physical foundation for efficient pressing. The several evenly distributed oil leakage holes on the outer surface of the oil pressing cylinder 4 are key channels for oil seepage and discharge. These evenly distributed leakage holes provide a sufficient and least resistant outflow path for the pressed oil, allowing oil, whether near the cylinder wall or near the center, to seep out relatively evenly and smoothly, minimizing the chance of oil residue inside the cylinder and improving oil yield.

[0035] See Figure 1 , Figure 2 , Figure 3The extrusion plate 3, the movable plate 701, and the oil pressing cylinder 4 are arranged coaxially and adapted to the inner diameter of the oil pressing cylinder 4. This is the geometric basis for ensuring a uniform and effective pressing process and smooth slag removal. Strict coaxiality means that when the extrusion plate 3 presses down, its force can be transmitted vertically and evenly to the movable plate 701 and the raw material layer between them. This avoids problems such as uneven force on the raw material, insufficient or excessive local compression, and obstruction of the oil seepage path caused by eccentric pressure. This ensures that the entire raw material cake is subjected to a balanced hydraulic force, maximizing the oil pressing efficiency and oil uniformity. At the same time, the external dimensions of the extrusion plate 3 and the movable plate 701 are set to adapt to the inner diameter of the oil pressing cylinder 4, so that they can move within the cylinder with minimal gaps but without friction or jamming.

[0036] See Figure 1 , Figure 2 , Figure 3 An oil outlet pipe 6 is connected to one side of the receiving tray 5. The oil outlet pipe 6 is connected to an external receiving device, providing a simple and functional direct discharge channel for the pressed oil collected in the receiving tray 5. After the oil completes its initial flow in the receiving tray 5, it can be continuously and smoothly guided to the outside through the directly connected oil outlet pipe 6 without going through complex internal pipelines or turning structures. This single-point, short-path connection method minimizes flow resistance and the risk of oil retention inside the equipment, significantly improves the efficiency of oil discharge, and can promptly remove the pressed oil from the system, avoiding prolonged exposure to high temperature or oxygen environment that would affect its quality. At the same time, the design of connecting the oil outlet pipe 6 to the external receiving device is a key link in realizing the closed loop of the automated oil pressing process. It builds a physical connection bridge between the oil pressing equipment and the subsequent storage or processing units, ensuring that the pressed crude oil can be continuously and closedly transported to the designated collection or refining stage.

[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The telescopic rod 702 passes through the traction ring 703 and is fixedly connected by the fastening nut 704. This connection is used to adjust the initial longitudinal installation position of the traction ring 703. This through connection forms a rigid physical connection between the telescopic rod 702 and the traction ring 703. Whether it is subjected to downward compression and reset force or to the huge upward force applied by the lifting member 705, the fastening nut 704 can reliably lock the traction ring 703 in the designed position of the telescopic rod 702, effectively preventing slippage, loosening or rotation during the force process. At the same time, the more critical function is that by tightening or loosening the fastening nut 704, the longitudinal installation position of the traction ring 703 on the telescopic rod 702 can be precisely changed.

[0038] The implementation principle of this embodiment is as follows: First, tea seed raw materials are loaded into the oil pressing cylinder 4, that is, the raw materials are placed between the extrusion plate 3 and the movable plate 701. The hydraulic rod 2 drives the extrusion plate 3 to move downward, squeezing the raw materials to extract oil. The oil seeps out through the oil leakage hole on the surface of the oil pressing cylinder 4 to the receiving plate 5 and is discharged through the oil outlet pipe 6. After pressing, when the hydraulic rod 2 retracts, the slag cleaning mechanism 7 starts simultaneously. The lifting component 705 pushes the traction ring 703 to move upward. Through the telescopic rod 702 fixed to it, the movable plate 701 is pushed upward, forcibly removing the cake-shaped residue in the oil pressing cylinder 4 from the cylinder wall. The initial height is adjusted by the fastening nut 704 of the telescopic rod 702 and the traction ring 703 to ensure the coaxial movement of the movable plate 701, the extrusion plate 3 and the oil pressing cylinder 4, so as to achieve efficient separation of oil residue and rapid discharge of residue.
