[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0032] Embodiment
[0033] As Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a pressure filtration structure for walnut oil pressing, including a support frame 1. The top of the support frame 1 is fixedly connected with a pressing assembly 2. The pressing assembly 2 includes a cylinder 21 and a tank body 22. The cylinder 21 is installed on the top of the support frame 1. The bottom end of the inner wall of the support frame 1 is fixedly connected with an oil outlet 25. The top of the oil outlet 25 is fixedly connected with the tank body 22. A filtering assembly 3 is fixedly connected inside the pressing assembly 2, and a scraping oil assembly 4 is fixedly connected to the outside of the filtering assembly 3.
[0034] The filtering assembly 3 includes a piston 31. The outside of the piston 31 is slidably connected to the inner wall of the tank body 22. The outside of the piston 31 is fixedly connected to a pressure column 23. A heating wire 32 is fixedly connected inside the tank body 22. An airbag I 33 is slidably connected inside the tank body 22. A scraping plate I W34 is slidably connected to one end of the tank body 22 far from the airbag I 33. A filter screen 35 is fixedly connected inside the scraping plate I 34. The support frame 1 serves as the basic structure of the entire device, providing a solid support and a stable operation platform. The pressing assembly 2 includes a cylinder 21 and a tank body 22. The cylinder 21 is installed on the top of the support frame 1. The piston 31 is pushed up and down in the tank body 22 by air pressure. The bottom of the tank body 22 is fixedly connected with an oil outlet 25 to ensure that the pressed oil can be discharged smoothly. The filtering assembly 3 mainly filters the pressed oil preliminarily through the filter screen 35 to remove impurities. The outside of the piston 31 is slidably connected to the inner wall of the tank body 22 and is connected to the cylinder 21 through the pressure column 23 to achieve precise pressing action. The tank body 22 is also equipped with a heating wire 32, and the heating temperature is in the range of 25 degrees to 40 degrees, which is used to heat the liquid flow rate of walnut oil and improve the oil pressing efficiency. The airbag I 33 is installed at one end inside the tank body 22 to adjust the pressure and achieve the effect of moving up and down. Then, through the movement of the scraping plate I 34, the residual oil adhering to the tank body 22 can be effectively scraped off, reducing waste.
[0035] Furthermore, as Figure 1 - Figure 2As shown in the figure: A pressure column 23 is fixedly connected to the driving end of the air cylinder 21. The outer side of the pressure column 23 is slidably connected to the inner wall of the tank body 22. A wall plate 24 is fixedly connected to the inner wall of the tank body 22 of the support frame 1. A pressure column 23 is fixedly connected to the driving end of the air cylinder 21. This connection ensures that the power of the air cylinder 21 can be directly transmitted to the pressure column 23, thereby driving the piston 31 to move effectively up and down in the tank body 22. The outer side of the pressure column 23 is slidably connected to the inner wall of the tank body 22. This sliding connection design not only ensures the stability and precise positioning of the pressure column 23 in the tank body 22, but also enables the pressure column 23 to move smoothly up and down, ensuring that the pressure can be evenly transmitted to the walnut material. A wall plate 24 is fixedly connected to the inner wall of the tank body 22. This wall plate 24 plays a role in strengthening the structure of the tank body 22, and at the same time provides additional support for the pressure column 23. The fixed connection of the wall plate 24 makes the entire tank body 22 structure more stable, capable of withstanding high-intensity pressing pressure, thereby improving the durability and working efficiency of the entire device.
[0036] In order to scrape the residual liquid inside the tank body 22 and reduce waste, as Figure 2 with Figure 4 shown in the figure: In this solution, the oil scraping assembly 4 includes a second scraper 41. The inside of the second scraper 41 is fixedly connected to the first airbag 33. The bottom end of the first scraper 34 is fixedly connected to a second airbag 42. The bottom end of the first airbag 33 is fixedly connected to a connecting column 43. The top end of the first scraper 34 is fixedly connected to the bottom end of the connecting column 43. The inside of the second scraper 41 being fixedly connected to the first airbag 33 ensures that when the heating wire 32 drives the walnut oil inside to heat up, the first airbag 33 can drive the second scraper 41 to perform the oil scraping operation through expansion and contraction, enabling the second scraper 41 to flexibly position inside the tank body 22, thereby scraping the oil more efficiently. Similarly, the second airbag 42 controls the up and down movement of the first scraper 34 through expansion and contraction, thereby effectively scraping the oil at different positions, and through the design of the connecting column 43, the first scraper 34 and the second scraper 41 can achieve linear movement and avoid deviation.
[0037] Working principle:
[0038] As Figure 1 - Figure 4 shown in the figure:
[0039] During use: First, start the cylinder 21. The power of the cylinder 21 can be directly transmitted to the pressure column 23, thereby driving the piston 31 to move effectively up and down within the tank body 22. At the same time, the pressure column 23 can move up and down smoothly to ensure that the pressure can be evenly transmitted to the walnut material. Then, the wall plate 24 provides a placement platform for the walnut material. Subsequently, the interior of the tank body 22 is also equipped with a heating wire 32, and the heating temperature ranges from 25 degrees to 40 degrees, which is used to heat the liquid flow rate of the walnut oil. When the walnut oil flows onto the filter screen 35, it flows through the filter and towards the oil outlet 25. At this time, due to the design of the heating wire 32, the airbag one 33 and the airbag two 42 expand. Then, through the buoyancy of the walnut oil, the filter screen 35 moves upward. After the squeezing is completed, open the oil outlet 25. At this time, under the gravity of the filter screen 35, it automatically slides downward, thereby scraping the inner wall of the tank body 22 to achieve the cleaning effect. And when the second scraper 41 and the first scraper 34 scrape the wall, due to the effect of achieving a one-line connection at both ends through the connecting column 43, it effectively prevents deviation during the wall scraping process.
[0040] The above is only a preferred embodiment of the present invention and is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
