[0031] Embodiment 1

[0032] Refer to Figures 1 to 4 , a vertical centrifugal discharging device, including a double-output motor 51, a discharge pipe 52 and a separation rotor 53, wherein:

[0033] The dual-output motor 51 includes a driving body 511 and a rotating shaft 512. The rotating shaft 512 has a hollow structure, is arranged in the middle of the driving body 511, and both ends are located outside the driving body 511. The driving body 511 is used to control the rotation of the rotating shaft 512;

[0034] The discharge pipe 52 is connected to one end of the rotating shaft 512;

[0035] The separation rotor 53 is fixedly connected to the other end of the rotating shaft 512.

[0036] Compared with the prior art, a vertical centrifugal discharge device involved in the present utility model is different in that the present application uses the dual-output motor 51 as a power source, and the rotating shaft 512 of the dual-output motor 51 is set to have a hollow structure to replace the hollow shaft in the traditional discharge device. In actual application, the dual-output motor 51 drives the separation rotor 53 to rotate through the rotating shaft 512. The separation rotor 53 rotates at a high speed to generate a strong centrifugal force to throw the grinding medium outwards, while the material can overcome the centrifugal force under the action of pressure and enter the inside of the separation rotor 53. The material entering the inside of the separation rotor 53 flows along the inner cavity of the rotating shaft 512 to the discharge pipe 52 and is finally output outwards. By adopting the design of the present application, there is no need to set parts such as belts, transmission shafts, and hollow shafts, that is, the use of parts is reduced, and thus the manufacturing cost and failure rate of the equipment can be reduced.

[0037] In this embodiment, a cavity 531 is formed inside the separation rotor 53, and a plurality of feed holes 532 are formed outside it. The plurality of feed holes 532 are all communicated with the cavity 531, and the cavity 531 is communicated with the inner cavity of the rotating shaft 512. In actual application, the material can enter the cavity 531 along the feed holes 532 under pressure and flow towards the inner cavity of the rotating shaft 512. Since the aperture of the feed holes 532 is smaller than the diameter of the grinding medium, the grinding medium cannot enter the inside of the separation rotor 53, and under the rotation of the separation rotor 53, the grinding medium will be continuously thrown out to avoid blocking the feed holes 532.

[0038] In this embodiment, the separation rotor 53 includes an upper end plate 533, a lower end plate 534, and a plurality of vertical plates 535. The upper end plate 533 is fixedly connected to the rotating shaft 512. The lower end plate 534 is disposed below the upper end plate 533. A plurality of vertical plates 535 are all arranged between the upper end plate 533 and the lower end plate 534 and are arranged in a circumferential direction. Both ends of the vertical plates 535 are fixedly connected to the upper end plate 533 and the lower end plate 534 respectively. One side of the vertical plate 535 is located outside the adjacent vertical plate 535, and the other side is located inside another adjacent vertical plate 535. The gap between two adjacent vertical plates 535 forms a feed hole 532. In practical applications, the material will adhere to the outer wall of the vertical plate 535 under the action of pressure. When the rotating shaft 512 drives the separation rotor 53 to rotate, the material will gradually tend to move inward along the outer wall of the vertical plate 535 until it seeps into the cavity 531 along the gap between the vertical plates 535. With the above design, the material can flow more smoothly into the cavity 531 along the feed hole 532.

[0039] Preferably, the vertical plate 535 is arc-shaped. With the above design, the diversion of the vertical plate 535 to the material can be more smooth.

[0040] In this embodiment, the driving body 511 includes a housing and a stator assembly and a rotor assembly installed inside the housing. The rotor assembly is arranged inside the stator assembly. The rotating shaft 512 is fixedly connected to the rotor assembly. In practical applications, through the cooperation of the magnetic field generated between the stator assembly and the rotor assembly, the rotor assembly rotates, and then drives the rotating shaft 512 to rotate.

[0041] In this embodiment, connection seats 54 are hermetically installed at both ends of the driving body 511. The rotating shaft 512 is rotatably connected to the connection seats 54; the discharge pipe 52 covers the outside of the rotating shaft 512 and is fixedly connected to the connection seats 54. With the above design, a sealed connection between the discharge pipe 52 and the rotating shaft 512 is achieved, and the discharge pipe 52 does not rotate with the rotating shaft 512. Furthermore, there is no need to set up a rotary joint to connect the discharge pipe 52 and the external pipeline, further reducing the use of parts.

[0042] In this embodiment, an oil injection hole 541 is provided on the connection seat 54. With the above design, it is convenient to inject lubricating oil into the gap between the connection seat 54 and the discharge pipe 52, thereby improving the smoothness of the rotation of the rotating shaft 512.
