Description

Technical Field

[0001] This utility model relates to the technical field of walnut oil filtration devices, and in particular to a walnut oil filtration device. Background Technology

[0002] In existing technologies, walnut oil filters tend to accumulate a lot of residue on their surface after long-term use, which reduces the oil filtration effect. Therefore, they need to be removed and cleaned frequently. Moreover, the residue still contains a certain amount of walnut oil, so the filtered residue needs to be collected and squeezed out again, which is cumbersome and inefficient. Utility Model Content

[0003] Therefore, it is necessary to provide a walnut oil filtration device to address the technical problem of low filtration efficiency of the aforementioned walnut oil filtration devices.

[0004] To achieve the above objectives, this utility model provides a walnut oil filtration device, including a frame, a filter screen mounted on the frame, a movable frame slidably connected to the frame, a push plate hinged to the movable frame, the push plate cooperating with the filter screen, a linear actuator mounted on the frame, the output end of the linear actuator connected to the movable frame, a lifting block slidably connected to the movable frame, a second linear actuator mounted on the movable frame, the output end of the second linear actuator connected to the lifting block, a limiting block for limiting the push plate mounted on the lifting block, the lifting block and the push plate hinged to the same connecting rod, and a fixed plate cooperating with the push plate for pressing on the frame.

[0005] Preferably, the lifting block is equipped with a vertical groove, and a fixed shaft is installed at the top of the connecting rod, with the fixed shaft slidably engaged in the vertical groove.

[0006] Preferably, the fixing plate is inclined, and the fixing plate is provided with a scraping groove. A spring is installed in the scraping groove, and a scraper is slidably engaged in the scraping groove. The output end of the spring is connected to the scraper.

[0007] Preferably, the frame is provided with mounting grooves on both sides, and limit block one and limit block two are respectively installed at both ends of the filter screen. Limit block one and limit block two are slidably engaged in the mounting grooves; limit block one is rotatably installed on the filter screen.

[0008] Preferably, the mounting groove has an opening at the bottom, and a protective plate is hinged to the opening.

[0009] Preferably, the bottom of the movable frame is equipped with a support block for supporting the push plate.

[0010] Compared with existing technologies, this technical solution has at least one of the following beneficial effects: 1. After the push plate is limited by the limiting block, the push plate can be tilted forward to push the residue for collection, thereby improving the oil filtration efficiency of the filter screen surface. 2. When the push plate is pushed to the fixed plate, it can cooperate with the fixed plate to squeeze and filter the residue, thereby compressing and reducing the volume of the residue. This allows the filter screen to be used for a longer period of time, while eliminating the need for or extending the time for collecting and pressing the filter residue again, thus improving work efficiency.

[0012] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0013] Please see Figures 1 to 4This application provides a walnut oil filtration device, including a frame 1, on which a filter screen 2 is fixedly installed. The filter screen 2 is preferably made of stainless steel or other materials that are not easily deformed. A movable frame 3 is slidably engaged on the frame 1. The frame 1 may be provided with a limiting groove to limit and allow the movable frame 3 to slide. A push plate 4 is hinged to the movable frame 3, and the push plate 4 is configured to cooperate with the filter screen 2. A linear actuator 5 is fixedly installed on the frame 1. The linear actuator 5 may be an electric cylinder. The output end of the linear actuator 5 is connected to the movable frame 3. A lifting block 6 is slidably engaged on the movable frame 3. A linear actuator 2 7 is fixedly installed. The linear actuator 2 7 can be an electric cylinder. The linear actuator 5 and the linear actuator 2 7 can be connected to an external signal processor. The output end of the linear actuator 2 7 is connected to the lifting block 6. A limiting block 8 for limiting the push plate 4 is fixedly installed on the lifting block 6. The lifting block 6 and the push plate 4 are hinged to the same connecting rod 9. A fixed plate 10 that cooperates with the push plate 4 for pressing is fixedly installed on the frame 1. The bottom of the frame 1 can be provided with an oil outlet with a solenoid valve. An oil pump can be installed on the frame 1 as needed to extract and filter the walnut oil in the frame 1.

[0014] In this embodiment, the walnut oil pressing outlet should be located directly above the center of the filter screen 2. When the linear actuator 5 moves the push plate 4 forward via the moving frame 3, the push plate 4 can rotate clockwise around the hinge due to its own weight. At this time, the linear actuator 7 can drive the limiting block 8 on the lifting block 6 to descend, so that the limiting block 8 can be locked between the moving frame 3 and the push plate 4, thereby allowing the push plate 4 to maintain an inclined state and push forward. The bottom tip of the push plate 4 can scrape and push the residue on the filter screen 2. When the residue is pushed to the fixed plate 10, the push plate 4 can cooperate with the fixed plate 10 to squeeze the residue together, so that the walnut oil contained in the residue can be extracted. The residue is squeezed out and collected into the frame 1. After squeezing, when the push plate 4 needs to retract, the linear actuator 7 can retract, so that the limit block 8 no longer limits the push plate 4. And through the setting of the connecting rod 9 hinged at one end of the lifting block 6, the push plate 4 can be pulled by the hinged connecting rod 9 to rotate counterclockwise and be lifted. Thus, during the process of the push plate 4 being pulled back by the linear actuator 5, the push plate 4 will not carry the residue on the filter screen 2 back, which ultimately reduces the number of times the filter screen 2 needs to be cleaned and the residue needs to be repressed for oil discharge, thus improving efficiency. When the linear actuator 5 applies a large force, so that the repressing effect of the push plate 4 and the fixed plate 10 on the residue is good, the additional process of collecting residue and repressing for oil discharge can be completely eliminated.

[0015] In some embodiments, to prevent damage to the connecting rod 9, a vertical groove 11 is provided on the lifting block 6, and a fixed shaft 12 is fixedly installed at the top of the connecting rod 9, which is slidably engaged in the vertical groove 11. Thus, when the lifting block 6 drives the limiting block 8 to rise, the fixed shaft 12 on the connecting rod 9 can first slide downwards in the vertical groove 11. After the limiting block 8 separates from the push plate 4, the connecting rod 9 then pulls the push plate 4 back to its original position via a hinge, thereby preventing the connecting rod 9 from breaking if it is directly pulled when the limiting block 8 is in position.

[0016] In some embodiments, to prevent the push plate 4 from resetting any residue that may be adhering to it, the fixing plate 10 is inclined. A scraping groove 13 is provided on the fixing plate 10, and a spring 14 is fixedly installed inside the scraping groove 13. A scraper 15 is slidably engaged inside the scraping groove 13, and the output end of the spring 14 is connected to the scraper 15. Thus, during the process of the push plate 4 being squeezed away and rotating back to its original position, the scraper 15, under the pressure of the spring 14, remains in contact with the deflected push plate 4, thereby scraping off some of the residue that may be adhering to it and reducing the probability of bringing the residue back. Due to the scraping groove 13, when the push plate 4 approaches the fixing plate 10, the scraper 15 can be squeezed and retracted into the scraping groove 13. To prevent oil from entering the scraping groove 13, a food-grade rubber pad can be installed on the inner wall of the scraping groove 13.

[0017] In some embodiments, to facilitate the replacement of the filter screen 2 and the collection of residue after re-pressurization, mounting grooves 16 are provided on both sides of the frame 1. Limiting blocks 17 and 18 are respectively installed at both ends of the filter screen 2, and both limiting blocks 17 and 18 are slidably engaged in the mounting grooves 16. Limiting block 17 slides into the mounting groove 16 before limiting block 18, so that limiting block 17 is preferably rotatably mounted on the filter screen 2. Thus, when the filter screen 2 is removed, after limiting block 18 fixedly mounted on the filter screen 2 slides out of the mounting groove 16, the filter screen 2 can deflect around limiting block 17, thereby facilitating the removal of residue from the filter screen 2. After that, when the filter screen 2 is removed, limiting block 17 can be pulled out along the mounting groove 16. At the same time, to prevent the push plate 4 from squeezing the fixing plate 10 and squeezing the filter screen 2, the bottom of the fixing plate 10 extends to the edge of the filter screen 2 and abuts against the surface of the filter screen 2.

[0018] In some embodiments, to facilitate the deflection of the filter screen 2 and protect the walnut oil inside the frame 1, an opening is provided below the mounting groove 16, and a protective plate 19 is hinged to the opening. When the protective plate 19 is opened, the space at the opening allows the filter screen 2 to slide out and deflect. When the protective plate 19 is hinged closed, its edge abuts against the frame 1, preventing impurities from entering the frame 1.

[0019] In some embodiments, to facilitate support of the bottom of the push plate 4, a support block 20 for supporting the push plate 4 is fixedly installed at the bottom of the movable frame 3. The support block 20 prevents the push plate 4 from continuing to deflect clockwise under the limit block 8.

[0020] The fixed connection and rotating installation in the above embodiments can all be achieved by welding, screw fasteners and other forms in the prior art, and the rotating installation can be achieved by bearings, circular rotating blocks and circular grooves. All of the above components are standard parts, and those that are not standard parts can also be specially customized, so the inventor will not elaborate further.

[0021] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0022] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
