[0003] Traditional separation methods often use screening devices with fixed apertures. These devices can only handle materials within a specific particle size range. When the particle size distribution of the material is wide, the fixed aperture screening device may not meet the requirements. This leads to the need to prepare screening devices with different apertures in actual operation, which increases equipment costs and operational complexity.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a separation device with adjustable sieve aperture for the preparation of oseltamivir in order to overcome the shortcomings in current practical applications. Utility Model Content

The driving end of the electric telescopic rod is fixedly connected to a connecting plate, and the connecting plate rotates to fit the H-shaped ring.

[0013] In a further technical solution, the adjusting assembly includes a fixed shaft, a first rotating plate, and a second rotating plate;

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] like Figure 1-5 As shown, this utility model embodiment provides a separation device with adjustable sieve aperture for oseltamivir preparation, including a base frame 1 and a separation box 2. The separation box 2 is fixedly connected to the base frame 1. A feed hopper 4 is provided on the side wall of the separation box 2. A stirring assembly 3 is provided inside the separation box 2. A discharge hopper 5 is fixedly connected to the lower end of the separation box 2. A U-shaped plate 6 is fixedly connected to the inner wall of the separation box 2. Multiple evenly distributed first U-shaped sieve plates 7 and second U-shaped sieve plates 8 are slidably connected to the inner wall of the U-shaped plate 6. The first U-shaped sieve plates 7 and the second U-shaped sieve plates 8 are perpendicular to each other. The upper end face of the first U-shaped sieve plate 7 abuts against the lower end face of the second U-shaped sieve plate 8. The side walls of the two second U-shaped sieve plates 8 and the two first U-shaped sieve plates 7 are all fixedly connected. A first support plate 11 is fixedly connected to the first U-shaped screen plate 7, and threaded rotating rods 12 are threadedly connected between the two first support plates 11 connected to the first U-shaped screen plate 7 and between the two first support plates 11 connected to the second U-shaped screen plate 8. One end of each threaded rotating rod 12 is rotatably connected to a second support plate 14, and a linkage component 15 is provided between the two threaded rotating rods 12. One end of one threaded rotating rod 12 is fixedly connected to a second motor 13. An adjustment component 16 is provided between the multiple second U-shaped screen plates 8. The adjustment component 16 is used to control the multiple second U-shaped screen plates 8 to move synchronously, thereby synchronously adjusting the distance between the multiple second U-shaped screen plates 8. An adjustment component 16 is also provided on the multiple first U-shaped screen plates 7.

[0028] Furthermore, a groove 9 is provided on the upper end of the inner wall of the U-shaped plate 6, and a limiting slider 10 is fixedly connected to the outer walls of both ends of each first U-shaped sieve plate 7 and second U-shaped sieve plate 8, and the limiting slider 10 is slidably connected to the inner wall of the groove 9.

[0029] Furthermore, the threads on both sides of the threaded rod 12 are in opposite directions.

[0030] Specifically, the raw material to be screened is added to the separation box 2 through the feed hopper 4. The raw material on the first U-shaped screen plate 7 and the second U-shaped screen plate 8 is stirred by the stirring component 3. The second motor 13 drives the threaded rotating rod 12 to rotate. Then, the threaded rotating rod 12 drives the corresponding first U-shaped screen plate 7 to move closer or further apart through the first support plate 11. After that, the first U-shaped screen plate 7 drives the remaining first U-shaped screen plates 7 to move synchronously through the distance adjustment component 16, thereby adjusting the distance between two adjacent first U-shaped screen plates 7. The threaded rotating rod 12 drives another threaded rotating rod 12 to rotate through the linkage component 15. Then, the threaded rotating rod 12 drives the second U-shaped screen plate 8 to move through the corresponding first support plate 11. After that, the second U-shaped screen plate 8 drives the remaining second U-shaped screen plates 8 to move synchronously through the corresponding distance adjustment component 16, adjusting the distance between two adjacent second U-shaped screen plates 8, thereby adjusting the aperture size formed by the two adjacent second U-shaped screen plates 8 and the two adjacent first U-shaped screen plates 7, thus enabling the screening of raw materials of different particle sizes.

[0031] It can be understood that the distance between adjacent first U-shaped screen plates 7 is not less than the distance between the first U-shaped screen plate 7 and the inner wall of the return plate 6, thereby ensuring that the raw material cannot enter the discharge hopper 5 from between the first U-shaped screen plate 7 and the inner wall of the return plate 6. The second U-shaped screen plate 8 is the same as the first U-shaped screen plate 7.

[0032] like Figure 1 and Figure 2 As shown, the stirring assembly 3 includes a first motor 31, a stirring shaft 32, and stirring blades 33; the first motor 31 is fixedly connected to the top cover of the separation box 2, the driving end of the first motor 31 is fixedly connected to the stirring shaft 32, and a plurality of evenly distributed stirring blades 33 are fixedly connected to the outer wall of the stirring shaft 32.

[0033] Specifically, the first motor 31 is started, and then the first motor 31 drives the stirring blade 33 to rotate through the stirring shaft 32, thereby stirring the raw material to be screened and speeding up the screening efficiency.

[0034] like Figure 3-5As shown, the linkage assembly 15 includes a first bevel gear 151, a second bevel gear 152, a sleeve 156, a limiting groove 157, and a limiting key 158; the first bevel gear 151 is fixedly sleeved on the outer wall of one threaded rotating rod 12, and the sleeve 156 is slidably sleeved on the outer wall of the other threaded rotating rod 12. The limiting groove 157 is formed on the outer wall of the threaded rotating rod 12, and the limiting key 158 is fixedly connected to the inner wall of the sleeve 156, and the limiting key 158 is slidably connected to the inner wall of the limiting groove 157. The second bevel gear 152 is fixedly sleeved on the outer wall of the sleeve 156, and the second bevel gear 152 meshes with the first bevel gear 151.

[0035] Furthermore, an H-ring 153 is fixedly fitted onto the outer wall of the sleeve 156, and an electric telescopic rod 155 is fixedly connected to the upper end of the return plate 6. A connecting plate 154 is fixedly connected to the driving end of the electric telescopic rod 155, and the connecting plate 154 rotates to fit the H-ring 153.

[0036] Specifically, when the first U-shaped screen plate 7 and the second U-shaped screen plate 8 need to move synchronously to adjust the sieve aperture, the electric telescopic rod 155 is extended. Then, the drive end of the electric telescopic rod 155 drives the connecting plate 154 to approach the first bevel gear 151. After that, the connecting plate 154 drives the sleeve 156 to slide through the H-ring 153. Subsequently, the sleeve 156 drives the second bevel gear 152 to approach the first bevel gear 151 until the second bevel gear 152 meshes with the first bevel gear 151. Then, the second motor 13 drives the threaded rotating rod 12 to rotate. The threaded rotating rod 12 drives the first U-shaped screen plate 7 to move through the corresponding first support plate 11. The threaded rotating rod 12 synchronously drives the first bevel gear 151 to move. Wheel 151 rotates, and then the first bevel gear 151 drives the sleeve 156 to rotate through the second bevel gear 152. Subsequently, the sleeve 156 drives another threaded rod 12 to rotate through the limit key 158. Then, the threaded rod 12 drives the second U-shaped screen plate 8 to move through the corresponding first support plate 11. When only the first U-shaped screen plate 7 needs to move to adjust the sieve aperture, the electric telescopic rod 155 is controlled to retract. Then, the drive end of the electric telescopic rod 155 drives the connecting plate 154 away from the first bevel gear 151. After that, the connecting plate 154 drives the sleeve 156 to move through the H-ring 153. Then, the sleeve 156 drives the second bevel gear 152 to disengage from the first bevel gear 151.

[0037] like Figure 3 As shown, the adjusting assembly 16 includes a fixed shaft 161, a first rotating plate 162, and a second rotating plate 163; a fixed shaft 161 is fixedly connected to each first U-shaped screen plate 7, and the first rotating plate 162 and the second rotating plate 163 are rotatably sleeved on the outer wall of the fixed shaft 161, and the first rotating plate 162 is rotatably connected to the second rotating plate 163 on the adjacent first U-shaped screen plate 7.

[0038] Specifically, when the first U-shaped screen plates 7 move away from or close to each other, the first U-shaped screen plates 7 respectively drive the corresponding fixed shafts 161 to move relative to each other. Then, the fixed shafts 161 drive the adjacent fixed shafts 161 to move through the cooperation of the first rotating plate 162 and the second rotating plate 163. Then, the fixed shafts 161 drive the corresponding first U-shaped screen plates 7 to move, thereby adjusting the distance between the adjacent first U-shaped screen plates 7.

[0039] The working principle of this utility model is as follows: Raw materials to be screened are added to the separation box 2 through the feeding hopper 4. The first motor 31 is started, and then the first motor 31 drives the stirring blades 33 to rotate via the stirring shaft 32, thereby agitating the raw materials to be screened. Next, the second motor 13 drives the threaded rotating rod 12 to rotate. The threaded rotating rod 12 drives the first U-shaped screen plate 7 to move via the corresponding first support plate 11. The first U-shaped screen plate 7 drives the corresponding fixed shaft 161 to move relative to each other. Then, the fixed shaft 161 drives the adjacent fixed shaft 161 to move through the cooperation of the first rotating plate 162 and the second rotating plate 163. The fixed shaft 161 then drives the corresponding first U-shaped screen plate 7 to move, thereby adjusting the distance between adjacent first U-shaped screen plates 7. The threaded rotating rod 12 synchronously drives the first bevel gear 151 to rotate. Then, the first bevel gear 151 drives the sleeve 156 to rotate via the second bevel gear 152. Subsequently, the sleeve 156 drives another threaded rotating rod 12 to rotate via the limit key 158. Afterwards, this threaded rotating rod 12 drives the corresponding first... The support plate 11 drives the second U-shaped screen plate 8 to move. The second U-shaped screen plate 8 then adjusts the spacing between adjacent second U-shaped screen plates 8 via the adjusting assembly 16. Additionally, when the first U-shaped screen plate 7 and the second U-shaped screen plate 8 need to move synchronously to adjust the sieving aperture, the electric telescopic rod 155 is extended. The drive end of the electric telescopic rod 155 then drives the connecting plate 154 closer to the first bevel gear 151. Afterwards, the connecting plate 154 drives the sleeve 156 to slide via the H-ring 153. Subsequently, the sleeve 156... The second bevel gear 152 is driven to approach the first bevel gear 151 until the second bevel gear 152 meshes with the first bevel gear 151; when only the first U-shaped screen plate 7 needs to move to adjust the sieve aperture, the electric telescopic rod 155 is controlled to retract, and then the drive end of the electric telescopic rod 155 drives the connecting plate 154 away from the first bevel gear 151. After that, the connecting plate 154 drives the sleeve 156 to move through the H-ring 153, and then the sleeve 156 drives the second bevel gear 152 to disengage from the first bevel gear 151.
