Its chemical name is florfenicol, which belongs to the amide antibiotic class. Its mechanism of action is similar to that of chloramphenicol, inhibiting bacterial growth by interfering with bacterial protein synthesis. In the production process of florfenicol powder, the screening device is an important equipment to ensure product quality and uniform particle size. This type of device is mainly responsible for screening and separating the crushed florfenicol raw material powder according to a specific particle size range to remove oversized or undersized particles and possible impurities.

[0026] In this embodiment, a plurality of sieves 5 are arranged from bottom to top, and the sieve holes of the lower sieves 5 are smaller than the sieve holes of the higher sieves 5, so as to realize the classification and screening of florfenicol powder of different particle sizes. The dispersion mechanism 3 is used to break up the florfenicol powder delivered into the box 1, and the broken florfenicol powder is evenly dispersed on the sieve 5. The vibration mechanism 6 on the sieve 5 generates vibration to drive the sieve 5 to vibrate, thereby improving the screening speed of the florfenicol powder by the sieve 5. The setting of the driving mechanism 13 can drive the sweeping mechanism 8 The sweeping mechanism 8 is in operation so that the florfenicol powder remaining on the screen 5 is swept toward the discharge port 14, and then the discharge port 14 is opened by the opening and closing mechanism 26, so that the florfenicol powder is swept to the inside of the discharge port 14 and then falls into the inside of the collecting box 23 and is collected by the collecting box 23, so that people can take out the florfenicol powder remaining on the screen 5, thereby avoiding the waste of florfenicol powder. At the same time, the purpose of cleaning the screen 5 is also achieved, and the problem of reduced screening efficiency of the screen 5 for the florfenicol powder due to clogging of the screen holes of the screen 5 is prevented.

[0027] Specifically, the inner bottom wall of the discharge port 14 is not higher than the top of the sieve 5 , so that the florfenicol powder on the sieve 5 can enter the inside of the discharge port 14 .

[0028] like Figure 1 and Figure 2 As shown, the dispersing mechanism 3 is a first motor arranged on the top of the box body 1. The output end of the first motor passes through the interior of the box body 1 and is then provided with a plurality of rod bodies 4 through a casing. A feeding port 2 is passed through the top of the box body 1, and the rod bodies 4 are located below the feeding port 2. When the first motor is started, the output end of the first motor drives the rod body 4 to rotate, and the rod body 4 causes the florfenicol powder falling from the feeding port 2 to contact with the rod body 4 and be dispersed, thereby achieving the purpose of the dispersing mechanism 3 to disperse the florfenicol powder.

[0030] like Figure 1 and Figure 4 As shown, the opening and closing mechanism 26 is a mounting shell arranged on the outside of the box body 1, and an electric push rod 15 is arranged inside the mounting shell. A blocking block 16 for blocking the discharge port 14 is arranged at the output end of the electric push rod 15, and a discharge shell 17 with openings on the top and bottom is penetrated through the bottom of the mounting shell. The mounting shell provides an installation position for the electric push rod 15. The electric push rod 15 is started to extend the telescopic end of the electric push rod 15. When the telescopic end of the electric push rod 15 is extended, it drives the blocking block 16 to block the discharge port 14, thereby preventing powders of different particle sizes from indiscriminately entering the discharge port 14 and then being collected by the collecting box 23 when the screen 5 is vibrated and screened. The blocking block 16 is controlled by the electric push rod 15 to stay away from the discharge port 14, so as to realize the opening of the discharge port 14.

[0032] like Figure 1 As shown, the driving mechanism 13 is a second motor arranged outside the box body 1. The output end of the second motor passes through the inside of the box body 1 and is connected to the end of one group of rollers. When the second motor is started, the second motor drives the rollers to rotate inside the box body 1, so that the sweeping mechanism 8 moves.

[0033] like Figure 1 and Figure 4 As shown, the clamping assembly 18 is a mounting plate arranged outside the box body 1, and a plurality of groups of springs 19 are symmetrically arranged on the top of the mounting plate, and a group of lifting plates 20 are arranged on the top of the plurality of groups of springs 19. A limiting hole 22 is penetrated through the top of the mounting plate, and a guide column 21 is penetrated inside the limiting hole 22. The top of the guide column 21 is fixedly connected to the bottom of the lifting plate 20, and a yield opening 25 matching the discharge shell 17 is opened on the top of the collecting box 23.

[0034] In this embodiment, the lifting plate 20 is pressed to lower its height, and the collecting box 23 is placed on the lifting plate 20. The lifting plate 20 is released, and the rebound effect of the spring 19 drives the lifting plate 20 to rise. At this time, the top of the collecting box 23 is against the bottom of the mounting shell, and the discharge shell 17 enters the interior of the clearance port 25, thereby realizing the clamping connection between the collecting box 23 and the mounting shell, and also facilitating the replacement of the collecting box 23.

[0035] like Figure 1 and Figure 4 As shown, a plurality of transparent windows 24 are provided on the collection box 23 . The transparent windows 24 are provided to facilitate people to observe the collection of the florfenicol powder inside the collection box 23 .

The discharge pipe 27 is used to discharge the florfenicol powder in the box body 1 to the outside. When the solenoid valve 28 is opened, the florfenicol powder can be discharged through the discharge pipe 27.

[0037] Working principle: when in use, the first motor is started, and the output end of the first motor drives the rod body 4 to rotate, and the rod body 4 makes the florfenicol powder falling from the feeding port 2 contact with the rod body 4 and be broken up, so that the purpose of the dispersing mechanism 3 to break up the florfenicol powder is achieved, and the broken florfenicol powder is evenly dispersed on the screen 5, and one group of rollers is driven to rotate by the second motor, and one group of rollers drives another group of rollers to rotate through the belt strip 10, and the belt strip 10 drives the brush strip 11 to clean the florfenicol powder on the screen 5 when it moves, and the screen 5 can also dredge the sieve holes at the same time, and the brush strip 11 sweeps the florfenicol powder to the discharge port 14, and then the electric push rod 15 controls the block 16 to stay away from the discharge port 14, so as to open the discharge port 14, so that the florfenicol powder can be discharged to the discharge port 14. After being swept to the inside of the discharge port 14, the florfenicol powder falls into the inside of the collection box 23 and is collected by the collection box 23, which makes it easy for people to take out the florfenicol powder remaining on the screen 5, avoiding the waste of florfenicol powder. At the same time, the purpose of cleaning the screen 5 is also achieved, and the sieve holes of the screen 5 are prevented from being blocked, resulting in the problem of reduced screening efficiency of the florfenicol powder by the screen 5; the height of the lifting plate 20 is lowered by pressing the lifting plate 20, and the collection box 23 is placed on the lifting plate 20, and the lifting plate 20 is released. The rebound effect of the spring 19 drives the lifting plate 20 to rise. At this time, the top of the collection box 23 is against the bottom of the mounting shell, and the discharge shell 17 enters the inside of the clearance port 25, realizing the clamping connection between the collection box 23 and the mounting shell, and also facilitating the replacement of the collection box 23.
