[0009] The beneficial effects of this utility model are:

[0010] 1. This utility model uses a drive motor to rotate the shaft and centrifugal screening box. The centrifugal force generated by the centrifugal screening box dynamically separates the raw materials, so that qualified raw material particles are thrown out of the centrifugal screening box and slide out of the screening box body, while unqualified raw material particles are left in the centrifugal screening box, thereby realizing the screening of raw materials.

[0011] 2. This utility model uses a dehumidifier to remove humid air from the screening box, thereby keeping the raw materials dry. The values ​​detected by the humidity sensor are displayed on the controller screen, making it convenient to observe the humidity level. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] like Figures 1 to 4 The raw material screening machine for preparing oseltamivir phosphate dry suspension of this utility model, as shown, includes a support frame 1, a controller 2 mounted on the support frame 1, a screening box 3 fixedly connected to the support frame 1, a feed pipe fixedly connected to the screening box 3, a fixed plate 4 fixedly connected inside the screening box 3, a first reinforcing frame 5 fixedly connected to the screening box 3, a drive motor 6 fixedly mounted on the first reinforcing frame 5, a rotating shaft 7 connected to the top end of the output shaft of the drive motor 6, and a... There is a centrifugal screening box 8, which is rotatably connected to a fixed plate 4 and a rotating shaft 7. The centrifugal screening box 8 is used to screen raw material particles. A discharge pipe 9 is connected to the centrifugal screening box 8, and an electric valve 10 is installed on the discharge pipe 9. A humidity sensor 11 is installed inside the screening box 3 to detect the humidity inside the screening box 3. A dehumidifier 17 is fixedly installed on the screening box 3 to remove moisture from inside the screening box 3.

[0019] The controller 2 is equipped with a display screen.

[0020] The centrifugal screening box 8 has an inclined surface inside.

[0021] The centrifugal screening box 8 is made of 316L stainless steel screen.

[0022] A second reinforcing frame 12 is fixedly connected to the screening box 3. An electric push rod 13 is fixedly installed on the second reinforcing frame 12. A connecting rod 14 is connected to the telescopic rod of the electric push rod 13. Two slide rail frames 16 are fixedly connected inside the screening box 3. A cover plate 15 is slidably connected between the two slide rail frames 16. The cover plate 15 is connected to the connecting rod 14. The cover plate 15 is used to prevent unqualified raw materials from being thrown out of the centrifugal screening box 8 during operation.

[0023] The working principle of this utility model is as follows: After the raw material to be screened is poured into the centrifugal screening box through the feed pipe of the screening box, the electric push rod drives the connecting rod and the cover plate to move, so that the cover plate moves to the top of the centrifugal screening box, thereby covering the top of the centrifugal screening box. Then, the drive motor drives the rotating shaft and the centrifugal screening box to rotate. The centrifugal force generated by the centrifugal screening box dynamically separates the raw material, so that qualified raw material particles are thrown out of the centrifugal screening box and slide out of the screening box, while unqualified raw material particles are left in the centrifugal screening box, thereby realizing the screening of raw materials. During the screening, the dehumidifier removes the moisture in the screening box, thereby keeping the raw material dry. The value detected by the humidity sensor is displayed on the controller display screen, so as to facilitate the observation of the humidity value. After the raw material screening is completed, when it is necessary to discharge unqualified raw material, the electric valve is controlled to open the discharge pipe, and the unqualified raw material will slide out through the discharge pipe.
