[0002] Pharmaceutical intermediate screening is a common process in pharmaceutical manufacturing, mainly for the separation and purification of pharmaceutical intermediates. This process usually involves the use of specific equipment, such as filtration and screening devices, to screen the raw materials and separate the principles of different particle sizes by screening.

[0003] In the prior art, after the pharmaceutical intermediates are screened, the pharmaceutical intermediates with larger particle sizes are processed again. Usually, the pharmaceutical intermediates located above the filter plate are taken out and processed again to make the particle sizes of the pharmaceutical intermediates uniform. The pharmaceutical intermediates located above the filter plate cannot be directly subjected to a secondary grinding process while the filtering and screening device is filtering the pharmaceutical intermediates.

[0032] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0033] like Figure 1-5 As shown, a screening device for processing pharmaceutical intermediates includes a shell 1 with a square accommodating chamber, a feeding part 2 is provided above the shell 1, a screening plate 3 is provided in the shell 1 just below the feeding part 2, a material receiving frame 4 is provided on the lower side of the screening plate 3, the left part of the screening plate 3 is hinged to the shell 1, and a movable plate 5 that moves in the up and down directions is abutted on the lower right side of the screening plate 3, an elastic part is provided below the movable plate 5, a material guiding mechanism that makes the screening plate 3 tilt reciprocatingly downward is provided above the right side of the screening plate 3, and a grinding mechanism is provided on the lower right side of the screening plate 3.

[0034] The technical solution of this embodiment is adopted, and the shell 1 is used to process the pharmaceutical intermediates entering the shell 1. The pharmaceutical intermediates are fed from the feeding part 2 and fall onto the top of the screening plate 3 after entering. The screening plate 3 screens the pharmaceutical intermediates. The left side of the screening plate 3 is hinged to the rotating rod fixedly connected to the shell, and the right side of the screening plate 3 is overlapped on the movable plate 5. The movable plate 5 supports the right end of the screening plate 3, and the lower part of the movable plate 5 slides in the slide groove. The elastic part supports the movable plate and resets the movable plate 5 at the same time. The material guiding mechanism tilts the screening plate 3 downward, so that the screened pharmaceutical intermediates move along the downward tilt direction of the screening plate 3 and move to the position of the grinding mechanism for processing. When the screening plate 3 is reset, it vibrates, thereby preventing the pharmaceutical intermediates from clogging the screening plate. The material receiving frame 4 collects the screened pharmaceutical intermediates.

[0035] Reference Figure 1-4 : The feeding part 2 includes a blanking frame 21 with a downward closing, and sliding grooves are provided on the front and rear sides of the blanking frame 21. Two blanking plates 22 staggered in the upper and lower directions are slidably connected in the sliding grooves of the blanking frame 21. The front and rear sides of the blanking plate 22 are provided with a transmission mechanism 23 for controlling the movement of the two blanking plates 22. The transmission mechanism 23 includes a double-headed threaded screw 231, and one end of the double-headed threaded screw 231 is transmission-connected to the first motor 232. The double-headed threaded screw 231 is fixedly assembled and connected to the upper side of the shell 1. One side of the two blanking plates 22 is threadedly connected to the double-headed threaded screw 231 with a connecting block 233. The two connecting blocks 233 are symmetrically arranged, and the other side of the blanking plate 22 is connected to a sliding mechanism; the sliding mechanism includes two sliding rods 24 in the upper and lower directions, and the upper and lower blanking plates 22 are slidably connected to the two sliding rods 24 in turn, and the two ends of the sliding rods 24 are fixedly connected to a fixed seat 25.

[0036] In this embodiment, the blanking frame 21 is used for blanking, the blanking plate 22 slides in the sliding groove, and the transmission mechanism 23 is used to control the movement of the blanking plate 22, thereby controlling the blanking. After the blanking plate 22 moves, the range of blanking changes, thereby avoiding the accumulation of pharmaceutical intermediates in the same position during blanking. When the double-headed threaded screw 231 rotates, the two connecting blocks 233 move relative to each other, thereby driving the two blanking plates 22 to move. The threads at both ends of the double-headed threaded screw 231 are arranged symmetrically, so that when the double-headed threaded screw 231 rotates, the movement directions of the two connecting blocks 233 are opposite, and the sliding rod 24 is used to support the blanking plate 22 and make the two blanking plates 22 move smoothly at the same time; through the staggered arrangement of the two blanking plates 22, the two blanking plates 22 can control the opening and stopping of blanking, and at the same time can control the position and range of blanking.

[0037] Reference Figure 4: The material guiding mechanism includes an eccentric wheel 61, which is slidingly connected to the screening plate 3. The eccentric wheel 61 is transmission-connected to a transmission shaft 62, which is rotationally connected to the housing through a bearing, and the transmission shaft 62 is transmission-connected to a second motor 63. There are two eccentric wheels 61, which are located on the front and rear sides of the screening plate 3.

[0038] In this embodiment, when the eccentric wheel 61 rotates, the contact position between the screen plate 3 and the eccentric wheel 61 is different, and the inclination angle of the screen plate 3 is different. The transmission shaft 62 is used to drive the eccentric wheel 61 to rotate, and the second motor 63 is used to drive the transmission shaft 62 to rotate. The two eccentric wheels 61 are located on the front and rear sides of the screen plate 3 to avoid one end of the screen plate 3 from tilting when it tilts downward. When the eccentric wheel 61 is located in the middle of the screen plate 3, it is inconvenient to unload the material.

[0039] Reference Figure 4 The grinding mechanism includes two grinding rollers 71 , which are connected to a driving member, and a material receiving frame 72 is provided below the grinding rollers 71 .

[0040] In this embodiment, the grinding roller 71 is used to process the pharmaceutical intermediates, and the material receiving frame 72 collects the polished pharmaceutical intermediates. The grinding roller 71 on the left rotates clockwise to drive the pharmaceutical intermediates between the two grinding rollers 71 for processing.

[0041] Reference Figure 4 : A baffle plate 11 fixedly connected to the upper side of the shell 1 is provided above the right side of the screening plate 3.

[0042] In this embodiment, the material baffle plate 11 is used to prevent the feed part from falling directly to the position of the grinding roller 71 during the material discharge process. At the same time, the gap between the material baffle plate 11 and the screening plate 3 is small, so when the screening plate 3 tilts downward, the gap space between the material baffle plate 11 and the screening plate 3 is fixed, which can control the amount of material discharged from the screening plate 3 to the grinding roller 71.

[0043] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0044] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed herein shall be covered by the claims of the present invention.
