[0038] In combination Figures 1 to 4 As shown, the vibration dryer provided by the embodiment is used to complete material drying and improve drying efficiency.

[0039] In actual production, the materials that can be dried by the vibration dryer include but are not limited to powder coatings, lithium battery positive electrode materials, waste resins, etc. In the embodiment, the material dried by the vibration dryer is specifically radioactive medium.

[0040] Specifically, the vibration dryer comprises a drying kettle 100, a filter 200, and a vibration assembly 300: the bottom of the drying kettle 100 is provided with a liquid outlet pipe 110 and a heating port, the heating port is in communication with the hot outlet of an external heating device, the top of the drying kettle 100 is provided with a feeding port 120, the feeding port 120 is in communication with the discharge port of the upstream equipment; the filter 200 is fixedly arranged in the drying kettle 100 and is correspondingly arranged with the liquid outlet pipe 110; the vibration assembly 300 is arranged outside the drying kettle 100 and is in driving connection with the drying kettle 100 to drive the drying kettle 100 to vibrate.

[0041] As the filter 200 is arranged in the drying kettle 100, and the filter 200 is arranged at the bottom of the drying kettle 100 corresponding to the liquid outlet pipe 110. After the material to be dried enters the drying kettle 100 from the inlet 120, the filter 200 can filter the free moisture in the material to be dried, and the filtered moisture is discharged out of the drying kettle 100 through the liquid outlet pipe 110. Then the heat medium enters the drying kettle 100 through the heating port, and the filtered material is dried by heating the drying kettle 100. During the whole process, as the free moisture in the material to be dried is filtered out and discharged out of the drying kettle 100, the moisture content of the filtered material in the drying kettle 100 can be reduced, thereby improving the drying efficiency. By vibrating the vibration assembly 300, the material is constantly rolling and flowing when the drying kettle 100 is vibrating. When the heat medium enters the drying kettle 100 from the heating port, the material flowing in the drying kettle 100 also increases the heating area of the material, and ensures that the filtered material in the drying kettle is evenly heated, thereby accelerating the evaporation of the moisture of the material, and further improving the drying efficiency.

[0042] In addition, in the process of vibrating the drying kettle 100 by the vibration assembly 300, in order to avoid displacement or separation of the filter 200, the filter 200 is fixedly arranged in the drying kettle 100 in the embodiment.

On the other hand, a certain gap is formed between the filter 200 and the liquid outlet pipe 110, so as to avoid that the material in the drying kettle 100 blocks the liquid outlet pipe 110, thereby affecting the liquid discharge speed of the liquid outlet pipe 110.

[0045] In some other embodiments, in order to further improve the filtering effect and avoid that the residue of the material to be dried blocks the liquid outlet pipe 110 during the filtering process, a plurality of filters 200 are arranged in the filter groove 130 along the depth direction of the filter groove 130, and the filtering precision of the plurality of filters 200 increases in sequence from the opening of the filter groove 130 to the bottom wall of the filter groove 130.

In this way, the water temporarily stored in the filter tank 130 can be discharged as soon as possible through the liquid outlet pipe 110, avoiding the water flowing directly on the bottom wall of the filter tank 130, so as to further improve the drying effect and drying efficiency.

[0047] The specific form of the filter element 200 can be adaptively set as a wedge-shaped filter screen, a plain filter screen, a twill filter screen, a sintered filter screen, a folded filter screen, etc. according to the actual situation of the material to be dried. In the embodiment, the filter element 200 is provided as a wedge-shaped filter screen. Due to the design of the wedge-shaped gap of the wedge-shaped filter screen, a larger opening area can be provided, thereby improving the filtering efficiency. In addition, the wedge-shaped filter screen is easy to clean, and at the same time, it has strong pressure resistance and can withstand high pressure difference and frequent cleaning. In addition, the wedge-shaped filter screen can be designed according to the properties of different materials to meet various filtering requirements.

[0048] The wedge-shaped filter screen is composed of a plurality of wire bars and a plurality of rib bars. The plurality of wire bars are spaced apart along a first direction to form a first screening group, and the plurality of rib bars are spaced apart along a second direction to form a second screening group. The first direction and the second direction are arranged at an included angle. The first screening group is connected above the second screening group to form the wedge-shaped filter screen. In the embodiment, the opening rate of the wedge-shaped filter screen is set to 11%, the distance between the adjacent two wire bars above is set to 0.2mm, and the distance between the adjacent two rib bars below is set to 18.5mm. In other embodiments, the size specifications are not limited to this.

During the filtering process, the liquid discharge pipe is in communication with the liquid outlet pipe 110, which is used to immediately discharge the water filtered out of the wedge-shaped filter screen from the drying kettle 100, so as to ensure the drying effect and drying efficiency. When the pressure difference between the inside and outside of the wedge-shaped filter screen reaches a set value, the backwashing pipe 140 is in communication with the liquid outlet pipe 110. At this time, the external backwashing device is started to discharge cleaning fluid to the wedge-shaped filter screen, and the cleaning fluid is used to backwash the wedge-shaped filter screen, so as to restore the filtering performance of the wedge-shaped filter screen, thereby ensuring the subsequent use effect of the wedge-shaped filter screen.

During the filtering process or the backwashing process, the liquid discharge pipe or the backwashing pipe 140 can be selectively communicated with the liquid outlet pipe 110 through the three-way valve, so as to avoid the manual communication between the liquid discharge pipe or the backwashing pipe 140 and the liquid outlet pipe 110, thereby improving the use convenience of the vibration dryer. The specific structure and working principle of the three-way valve are prior art, and will not be described here.

[0051] Preferably, the drying kettle 100 comprises a cylinder body 101, a jacket 102 and a heat preservation layer 103, the heat preservation layer 103 is wrapped outside the cylinder body 101, the jacket 102 is arranged between the heat preservation layer 103 and the cylinder body 101, the heating port is communicated with the jacket 102, and the liquid outlet pipe 110 and the feeding port 120 are both arranged on the cylinder body 101.

[0053] Preferably, the top of the drying kettle 100 is further provided with a vacuum pipe 150, the vacuum pipe 150 extends out of the heat preservation layer 103 and is communicated with an external vacuumizing device. During drying, the external vacuumizing device is operated, and the inside of the cylinder body 101 is vacuumized through the vacuum pipe 150, so as to reduce the air pressure in the cylinder body 101, realize low-temperature drying, reduce the influence of high temperature on the material, thereby reducing the decomposition rate of the material, and prolonging the service life of the material after drying.
