The sealing ring 20 is a ring-shaped structure made of rubber material, which plays a role in sealing the box cover 3. The box 1 has a gap therebetween, and a vibration frame 4 is arranged inside the box 1. The vibration frame 4 is made of stainless steel, and its inner wall is smooth so that no material residue will appear on the inner wall after the oil pressing raw material is put in. A screen 5 is arranged at the inner center of the vibration frame 4. The screen 5 is a metal mesh, and the mesh on it can pass through small soil blocks, residues and other impurities in the oil pressing raw material to play a screening role. Spring shock absorbers 6 are arranged on both sides of the vibration frame 4. The spring shock absorber 6 includes a No. 1 spring 16, a rubber block 17, a No. 2 spring 18 and a support rod 19.

Both sides of the No. 1 spring 16 are connected with rubber blocks 17, which are made of rubber material. Rubber, as a material with good damping properties, can effectively absorb and disperse vibration energy, especially when dealing with high-frequency vibrations. The rubber blocks 17 are arranged at both ends of the No. 1 spring 16 to provide additional damping during the compression and extension of the No. 1 spring 16, thereby reducing the vibration amplitude. The No. 2 spring 18 is arranged at the center of the No. 1 spring 16, and the No. 2 spring 18 plays a role in auxiliary shock absorption. A support rod 19 is arranged on one side of the No. 2 spring 18. The support rod 19 is a rod body made of metal material. One end of the support rod 19 is connected to the No. 2 spring 18, and the other end is connected to the rubber block 17. Through this structure, when the No. 1 spring 16 is in shock absorption work, the No. 2 spring 18 can reduce the burden of the No. 1 spring 16 by absorbing part of the vibration energy, so that the shock absorption effect is enhanced and the service life is extended. A vibration motor 7 is arranged on one side of the bottom of the vibration frame 4. The vibration motor 7 drives the vibration frame 4 to screen the soybeans in the frame through the eccentric blocks on both sides.

[0019] An air inlet duct 8 is connected to the center of the top of the box cover 3. The air inlet duct 8 is a large-section multi-channel folding tube. This type of tube can be folded at different angles so that the air inlet duct 8 can change its angle with the box cover 3 when the box cover 3 is opened, which facilitates the opening of the box cover 3. A negative pressure fan 9 is connected to one side of the air inlet duct 8. The negative pressure fan 9 provides air flow for the box body 1.

The large air deflector 10 is a funnel structure made of metal material, which makes the flow direction and distribution of the air sent in by the air inlet duct 8 be The optimization effect is achieved, so that the soybeans in the vibration frame 4 are evenly heated. The bottom of the large air guide cover 10 is connected with an electric heating wire 11. The electric heating wire 11 generates heat by energizing. Then the air flow sent in from the air inlet pipe 8 is heated by the electric heating wire 11 to generate hot air, which plays a role in uniformly heating the soybeans. An air outlet pipe 12 is arranged on the lower side of the inner part of the box body 1. The air outlet pipe 12 is a hard pipe made of plastic material, which plays a role in circulating the hot air in the box body 1. A filter screen 13 is arranged on one side of the air outlet pipe 12. The filter screen 13 can filter the discharged hot air so that fine impurities are retained to avoid polluting the environment. A small air guide cover 14 is arranged on one side of the filter screen 13. The small air guide cover 14 can regulate the flow direction of the hot air entering the air outlet pipe 12, thereby enhancing the air outlet efficiency.

[0020] Working principle: When using a vibration impurity removal device for oil pressing raw materials, open the box cover 3 through the handle 21, pour the soybeans used as the oil pressing raw materials into the vibration frame 4 at the center of the box body 1, and then cover the box cover 3 to prevent the soybeans from being contaminated by external environmental pollutants during the working process, start the vibration motor 7 set at one side of the bottom of the vibration frame 4, so that the vibration frame 4 starts to vibrate with the soybeans, so that impurities in the soybeans fall through the screen 5 set at the center of the vibration frame 4, so that the impurities in the soybeans, the raw material for oil pressing, are removed. During screening, the spring shock absorbers 6 set on both sides of the vibration frame 4 adjust the overall stiffness and damping characteristics of the system through the cooperation of the No. 1 spring 16 and the rubber block 17, so that the influence of the vibration of the vibration frame 4 during operation on other components of the box body 1 is further reduced. While the vibration frame 4 vibrates, Start the negative pressure fan 9 on one side of the box body 1 to generate air flow inside the box body 1 through the air inlet pipe 8. A large air guide cover 10 is provided at the air outlet of the air inlet pipe 8 to make the wind blow evenly to the vibration frame 4. A heating wire 11 is provided at the bottom of the large air guide cover 10. After being turned on synchronously, the incoming wind can be converted into hot air to heat the soybeans in the vibration frame 4. The vibration of the vibration frame 4 forms a frying process for the soybeans, and the soybeans can be evenly heated while removing impurities. Such a pretreatment process not only improves the work efficiency, but also helps to improve the final oil yield because it improves the physical and chemical properties of the soybeans. The hot air passes through the soybeans through the bottom of the vibration frame 4, enters the air outlet pipe 12 arranged on the lower side of the box body 1, and is discharged from the inside of the box body 1 to prevent internal components from being overheated and damaged, thereby extending the service life.
