[0018] The technical solution of the utility model is described clearly and completely below in conjunction with the specific embodiments of the utility model. The described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] like Figure 1-4 As shown, a vibration drying device provided by the utility model comprises a bracket 1 and a hollow tank body 2 which can contain materials, a feed port is arranged on the top of the tank body 2, a discharge port is arranged on the end of the tank body 2, the discharge port is hingedly connected with a closed door, and an observation window is arranged on the front surface of the closed door so that an operator can observe the drying condition inside the tank body 2 to improve its practical performance. The tank body 2 of the present application is also provided with an exhaust port for facilitating the discharge of gas after the evaporation of moisture in the material, and the tank body 2 is provided with a heating cavity 3 through which a heat medium can pass, and the heat medium of the present application is preferably any one of water vapor, warm water and oil, which is used to dry the material in the tank body 2.

[0021] like Figure 2 As shown, the inner wall of the tank body 2 is inlaid with transmission steel sheets 4 arranged perpendicularly to each other, and the transmission steel sheets 4 are softly connected to the inner tank body 2, which can reduce the wear of the connection between the vibration drying device of the present application and the tank body 2, reduce metal impurities, and thus improve the quality of subsequent product production. The tank body 2 is provided with a vibration component for driving its vibration, and the vibration component is an electric motor that can switch between forward and reverse rotation, such as Figure 3-4As shown, the vibration component includes a vibration shell 5 and a rotating shaft 6 arranged in the vibration shell 5. According to mechanical analysis, built-in eccentric blocks 7 arranged on the rotating shaft 6 are respectively installed in both ends of the vibration shell 5. The vibration shell 5 is provided with an external eccentric block 8 on the outer side of the axis of the built-in eccentric block 7, and the built-in eccentric block 7 and the external eccentric block 8 are arranged at an angle of 12.5-20° in the axial direction, which can effectively reduce the vibration amplitude of the vibration drying device of the present application during operation, reduce the wear of the connection between the vibration dryer and the tank body 2, and reduce the wear of the tank body 2 by the material. According to production comparison, the vibration drying device provided by the present application reduces the generation of metal impurities by more than 5% compared with the traditional vibration dryer. The upper end of the bracket 1 is connected to the tank body 2 through a spring, and the lower end of the bracket 1 is provided with a buffer layer, which can slow down the vibration of the vibration drying device and further reduce the swing amplitude of the tank body 2 under the action of the vibration component.

[0022] Example 2

[0023] On the basis of the above embodiments, this embodiment is to conveniently realize that two different vibration forces are generated during the forward and reverse rotation of the vibration component, and realize the vibration force adjustment of the vibration component during use, such as Figure 3-4 As shown, the side of the built-in eccentric block 7 facing the external eccentric block 8 of the present application is provided with an adjustment groove 9 with the center of the rotating shaft 6 as the axis, and the external eccentric block 8 is provided with a positioning pin corresponding to the adjustment groove 9, so that the positioning pin extends axially inward into the adjustment groove 9 of the built-in eccentric block 7. The adjustment groove 9 has built-in symmetrical wave-shaped groove pieces 11, and the wave crest spacing between the symmetrically arranged wave-shaped groove pieces 11 is smaller than the diameter of the positioning pin, and the wave trough spacing between the symmetrically arranged opposite wave-shaped groove pieces 11 is larger than the diameter of the positioning pin.

[0024] Example 3

[0025] On the basis of the above embodiment, in order to increase the service life of the vibration component, the present embodiment Figure 3 As shown, a detachable limit plate 12 is fixedly provided on the inner wall of the vibration shell 5 corresponding to the shoulder of the built-in eccentric block 7 in the present application. When the motor stops, the external eccentric block 8 and the built-in eccentric block 7 can be quickly merged into the same angle when they are reversed at a certain angle, thereby preventing the external eccentric block 8 from swinging left and right due to inertia when stopping, causing the locating pin on the external eccentric block 8 to hit the end of the adjustment slot 9 in the built-in eccentric block 7.

[0026] When the vibration drying device of the present application is working, the material is transported into the tank body 2 through the feed port, and then the feed port is sealed, and the tank body 2 is evacuated to -10kPa by a vacuum pump, and at the same time, a heat medium is introduced to fill the heating cavity 3, and then the vibration component is adjusted so that the built-in eccentric block 7 and the external eccentric block 8 are arranged at an angle of 12.5-20° in the axial direction, and the vibration component is started. The material in the vacuum tank body 2 is vibrated by the vibration force generated by the vibration component, so as to increase the heating area of ​​the material and ensure that the material is heated evenly, thereby accelerating the evaporation of moisture in the material and improving the drying effect of the material. The dried material meets the production requirements of the next process; it effectively solves the problem that the vibration dryer used for the existing ternary material has a large vibration amplitude with the vacuum tank during the vibration drying process, which easily increases the wear of the material on the vibration dryer, thereby causing metal impurities to mix into the material.
