Description

Technical Field

[0001] This utility model relates to the technical field of oil outlet mechanism for extruders, and in particular to an oil outlet mechanism for an oil cake extruder. Background Technology

[0002] In the oil cake processing, the oil outlet mechanism of the oil cake extruder is a key component, and its performance directly affects the oil extraction efficiency and the quality of the oil cake. Currently, the oil outlet mechanism of traditional oil cake extruders typically includes a base and an extrusion cylinder fixed on the base. The extrusion cylinder has oil outlet holes on its circumferential side to facilitate the discharge of oil during the extrusion process. However, existing technologies have significant shortcomings. After prolonged use, the oil outlet holes are easily clogged by oil cake residue, affecting the smoothness of oil flow. Traditional cleaning methods mostly involve manually disassembling the extruder barrel and cleaning each oil outlet hole individually, which is cumbersome and time-consuming, severely reducing production efficiency. Although some institutions have attempted to set up simple cleaning components, they cannot achieve sliding cleaning along the circumference of the extruder barrel, limiting the cleaning range and making it difficult to thoroughly remove residue from oil outlet holes in different locations.

[0003] Therefore, it is necessary to provide an oil outlet mechanism for an oil cake extruder to solve the above-mentioned technical problems. Utility Model Content

[0004] This utility model provides an oil outlet mechanism for an oil cake extruder, which solves the problems in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides an oil discharge mechanism for an oil cake extruder, including a base on which an extrusion cylinder is fixedly placed. The extrusion cylinder is stably supported above the base, and an oil discharge hole is opened through its circumferential side for discharging oil. A drive ring is slidably sleeved on the outer surface of the extrusion cylinder, and the drive ring is coaxially arranged with the extrusion cylinder and can slide along the outer surface of the extrusion cylinder. An arc-shaped cleaning plate is installed inside the drive ring, and the curvature of the arc-shaped cleaning plate matches the outer curvature of the extrusion cylinder. An oil brush is installed on its inner wall, and the oil brush contacts the surface of the extrusion cylinder. When the drive ring slides, the arc-shaped cleaning plate moves with it, and the oil brush cleans the residue in the oil discharge hole by means of contact friction with the extrusion cylinder. A handle extending outward is installed on the circumferential side of the drive ring. Applying external force through the handle can drive the drive ring to slide along the extrusion cylinder, providing power and guidance for the cleaning action. Preferably, a through hole is provided on the circumferential side of the drive ring, communicating with the internal space of the drive ring. A drive rod is slidably inserted into the through hole, and the drive rod can slide within the through hole. One end of the drive rod is fixedly connected to the surface of the arc-shaped cleaning plate, and the other end extends out of the drive ring and is provided with a handle. By gripping the handle, the drive rod can be moved. A spring is sleeved on the surface of the drive rod, and both ends of the spring are fixed to the arc-shaped cleaning plate and the inner wall of the drive ring, respectively. When the handle is pulled, the drive rod moves the arc-shaped cleaning plate away from the extrusion cylinder, while compressing the spring. After releasing the handle, the spring's restoring force pushes the arc-shaped cleaning plate back to its original position, so that the oil brush fits tightly against the extrusion cylinder, which facilitates adjustment of the contact force between the oil brush and the extrusion cylinder and enhances the cleaning effect. Preferably, a conical hopper is installed at the bottom of the base, and the conical hopper is integrally connected to the base. A filter hole is provided inside the bottom of the base, and the position of the filter hole corresponds to the opening at the top of the conical hopper, with the two being interconnected. The squeezed grease flows out through the oil outlet and then flows through the surface of the base to the filter hole. The filter hole prevents large pieces of residue from entering the conical hopper. The filtered grease enters the conical hopper, and the inclined inner wall of the conical hopper guides the grease to converge, facilitating grease collection. Preferably, an oil drain pipe is installed through the bottom of the conical hopper, communicating with the interior of the conical hopper. A valve is installed on the oil drain pipe, located between the conical hopper and the outlet of the oil drain pipe. The grease collected inside the conical hopper is discharged through the oil drain pipe. The valve controls the opening and closing of the oil drain pipe by its own opening and closing state, thereby achieving quantitative or timed discharge of grease. Preferably, the extrusion cylinder is formed by interlocking multiple extrusion tubes, with the interlocking parts of adjacent extrusion tubes fitting tightly together. This interlocking structure ensures the overall structural stability of the complete extrusion cylinder after the multiple extrusion tubes are combined, and also allows for the individual removal of a section of the extrusion tube for cleaning or replacement, thus improving maintenance convenience. Preferably, the base is equipped with multiple support legs at its bottom, which are equidistantly positioned at the four corners of the base, with their bottom ends in contact with the ground. The support legs, through their fixed connection to the base, provide stable support for the entire mechanism, preventing shaking during squeezing or cleaning from affecting operational accuracy. They also maintain a certain distance between the base and the ground, facilitating the installation and operation of the conical bucket and oil drain pipe.

[0006] Compared with related technologies, the oil outlet mechanism for an oil cake extruder provided by this utility model has the following beneficial effects: Compared with existing technologies, this oil outlet mechanism slides a drive ring on the outside of the extrusion cylinder and sets an arc-shaped cleaning plate with an oil brush inside the drive ring. The drive ring can be moved along the circumferential side of the extrusion cylinder by the handle, so that the oil brush can clean the oil outlet holes at different positions. Large-area cleaning can be achieved without disassembling the extrusion cylinder, which simplifies the cleaning operation and improves the cleaning efficiency.

[0007] Compared with existing technologies, the drive rod on the drive ring, in conjunction with the spring, can push the arc-shaped cleaning plate and oil brush to fit tightly against the surface of the extrusion cylinder. The contact force between the oil brush and the extrusion cylinder can be adjusted by holding the rod, ensuring that the oil brush can effectively penetrate into the oil outlet to remove residue during the sliding cleaning process, thus improving the thoroughness of the cleaning.

[0008] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0012] Please refer to the following: Figure 1-4An oil discharge mechanism for an oil cake extruder includes a base 1 on which an extrusion cylinder 3 is fixedly placed. The two are connected by bolts, ensuring the stability of the extrusion cylinder 3 during extrusion and providing a stable carrier for the extruded oil. Oil outlet holes 4 are evenly distributed in a matrix pattern on the periphery of the extrusion cylinder 3, allowing the extruded oil to be discharged smoothly from multiple locations. A drive ring 2 is slidably fitted onto the outer surface of the extrusion cylinder 3. The inner diameter of the drive ring 2 is slightly larger than the outer diameter of the extrusion cylinder 3, and the two are fitted with a clearance fit, allowing the drive ring 2 to slide smoothly along the axis of the extrusion cylinder 3. An arc-shaped cleaning plate 8 is installed inside the drive ring 2, and is welded to the inner wall of the drive ring 2. Its curvature perfectly matches the outer curvature of the extrusion cylinder 3, ensuring that the arc-shaped cleaning plate 8 fits tightly against the extrusion cylinder 3. An oil brush 12 is installed on the inner wall of the arc-shaped cleaning plate 8. The oil brush 12 is fixed with glue, and the bristles of the oil brush 12 are slightly longer than the gap between the arc-shaped cleaning plate 8 and the extrusion cylinder 3 to ensure that the bristles can penetrate into the oil outlet 4. A handle 10 is installed on the side of the drive ring 2. The handle 10 is connected to the drive ring 2 by welding. When the operator holds the handle 10 and applies force, the drive ring 2 can slide along the extrusion cylinder 3. At this time, the arc-shaped cleaning plate 8 moves with the drive ring 2. During the movement, the oil brush 12 cleans the residue in the oil outlet 4, achieving the technical effect of cleaning the oil outlet 4 without disassembling the extrusion cylinder 3, solving the problem of cumbersome traditional manual disassembly and cleaning. Example 2

[0013] Please refer to the following: Figure 1-4 The drive ring 2 has a through hole extending through its circumference, communicating with the internal space of the drive ring 2. A drive rod 13 is slidably inserted into the through hole, with a transition fit between the drive rod 13 and the through hole to ensure that the drive rod 13 can slide flexibly without wobbling. One end of the drive rod 13 is fixed to the surface of the arc-shaped cleaning plate 8 by welding, and the other end is provided with a handle 11, which is threadedly connected to the drive rod 13 for easy disassembly and replacement. A spring 9 is sleeved on the surface of the drive rod 13, and both ends of the spring 9 are welded and fixed to the inner wall of the arc-shaped cleaning plate 8 and the drive ring 2, respectively. During installation, first, the spring 9 is sleeved on the drive rod 13, then the drive rod 13 is inserted into the through hole, and finally the drive rod 13 is welded to the arc-shaped cleaning plate 8. When it is necessary to adjust the contact force between the oil brush 12 and the extrusion cylinder 3, the operator pulls the handle 11, and the drive rod 13 moves the arc-shaped cleaning plate 8 away from the extrusion cylinder 3, compressing the spring 9; when the handle 11 is released, the spring 9 returns to its original position and generates elastic force to push the arc-shaped cleaning plate 8 closer to the extrusion cylinder 3, so that the oil brush 12 is in close contact with the surface of the extrusion cylinder 3. Through this mechanical cooperation, the cleaning force can be adjusted according to the degree of blockage of the oil outlet 4, ensuring more thorough cleaning and making up for the shortcomings of traditional simple cleaning parts that are not thorough in cleaning. Example 3

[0014] Please refer to the following: Figure 1-4 The base 1 has a conical hopper 5 installed at its bottom end. The two are welded together to form an integral structure, ensuring a tight seal and preventing grease leakage. A filter hole 14 is provided inside the bottom of the base 1, which is connected to the conical hopper 5. The diameter of the filter hole 14 is smaller than that of the oil outlet 4, allowing for secondary filtration of the grease discharged from the oil outlet 4, preventing fine residue from entering the conical hopper 5. In the overall structure, the filter hole 14 serves as a filter, while the conical hopper 5 collects and gathers the grease. When the grease is discharged from the oil outlet 4, it flows onto the surface of the base 1 and then enters the conical hopper 5 through the filter hole 14. The inclined inner wall of the conical hopper 5 causes the grease to converge towards the bottom, achieving centralized collection and preventing grease from flowing around and causing waste and pollution. Example 4

[0015] Please refer to the following: Figure 1-4 The conical hopper 5 has an oil drain pipe 6 installed through its bottom end, and the two are connected by threads for easy installation, disassembly, and maintenance. A valve is installed on the oil drain pipe 6, and the valve is fixed to the oil drain pipe 6 using a flange connection. The installation sequence is to first connect the oil drain pipe 6 to the conical hopper 5, and then install the valve on the oil drain pipe 6. Grease collected in the conical hopper 5 can be discharged through the oil drain pipe 6. When grease collection is needed, the valve is opened, and the grease flows out from the oil drain pipe 6 under gravity; when collection is not needed, the valve is closed to prevent grease discharge. Through the cooperation of the valve and the oil drain pipe 6, effective control of grease discharge is achieved, facilitating grease collection according to production needs. Example 5

[0016] Please refer to the following: Figure 1-4 The extrusion cylinder 3 is formed by multiple extrusion tubes snapped together vertically. Each extrusion tube has a protrusion at its top and a groove at its bottom that matches the protrusion. The protrusion and groove are press-fitted to ensure stability after snapping. During installation, the protrusion of the lower extrusion tube is aligned with the groove of the upper extrusion tube, and pressure is applied to snap them together. This structural design allows for individual removal and cleaning or replacement of a section of the extrusion tube when its oil outlet 4 is severely blocked or damaged, without requiring overall disassembly, greatly improving maintenance efficiency. Simultaneously, the extrusion cylinder 3 formed by the snapping together of multiple extrusion tubes can collectively withstand the extrusion force during extrusion operations, ensuring the overall structural stability. Example 6

[0017] Please refer to the following: Figure 1-4The base 1 has four support legs 7 installed at its bottom end. These legs are bolted to the base 1 for easy installation and adjustment. Each support leg 7 is evenly spaced at one of the four corners at the bottom of the base 1. During installation, the support legs 7 are first placed at the corners of the base 1 and then secured with bolts. The support legs 7 provide support in the overall structure, maintaining a certain height between the base 1 and the ground, providing installation space for the conical bucket 5 and the oil drain pipe 6, while also preventing ground moisture from corroding the base 1. During the squeezing and cleaning operations, the four support legs 7 bear force evenly, ensuring the stability of the entire mechanism and preventing swaying that could affect operational accuracy.

[0018] The working principle of the oil discharge mechanism for an oil cake extruder provided by this utility model is as follows: When the oil cake extruder operates with the oil outlet mechanism, the raw material is first placed into the extrusion cylinder 3 for extrusion. The grease produced during the extrusion process is discharged through the oil outlet holes 4 on the side of the extrusion cylinder 3. The discharged grease flows into the conical hopper 5 through the filter holes 14 at the bottom of the base 1, and is then collected through the oil discharge pipe 6 at the bottom of the conical hopper 5 (after the valve is opened). When it is necessary to clean the oil outlet 4, the operator can hold the handle 10 on the drive ring 2 and slide the drive ring 2 along the outer surface of the extrusion cylinder 3. At this time, the arc-shaped cleaning plate 8 inside the drive ring 2 moves with the drive ring 2, and the oil brush 12 on the inner wall of the arc-shaped cleaning plate 8 performs preliminary cleaning on the surface of the extrusion cylinder 3 and the oil outlet 4. To enhance the cleaning effect, the operator can hold the lever 11 at the other end of the drive rod 13 and pull the drive rod 13. The drive rod 13 will move the arc-shaped cleaning plate 8 away from the extrusion cylinder 3, while simultaneously compressing the spring 9. After releasing the lever 11, the spring 9 will return to its original position, pushing the arc-shaped cleaning plate 8 and the oil brush 12 to fit tightly against the surface of the extrusion cylinder 3. During the sliding drive ring 2 process, the oil brush 12 can penetrate deeper into the oil outlet 4 more effectively to remove the residual oil cake residue inside. In addition, the extrusion cylinder 3 is composed of multiple extrusion tubes that are snapped together vertically. If more detailed cleaning or component replacement is required in certain areas, the extrusion tubes can be disassembled for operation. The support leg 7 at the bottom of the base 1 provides stable support for the entire mechanism, ensuring stable extrusion and cleaning processes.
