Description

Technical Field

[0001] This invention relates to the field of active pharmaceutical ingredient (API) production and processing technology, and specifically to an API production screening structure that facilitates waste collection. Background Technology

[0002] Chemical raw materials for pharmaceuticals refer to the raw materials used in the production of various preparations. They are the active ingredients in these preparations and are various powders, crystals, extracts, etc., prepared by chemical synthesis, plant extraction, or biotechnology for medicinal use. They require processing to become products that can be used in practice. With the continuous improvement of processing precision, excess waste is constantly generated during the processing. In order to reduce resource waste, these wastes need to be screened. At present, the existing waste collection equipment for solar photovoltaic panel processing still has some shortcomings in use. During screening, the screening effect is mostly achieved by using a shaking screen and the gravity of the waste itself, which has low screening efficiency and is very prone to clogging. In addition, dust pollution is also easily generated during the screening process.

[0003] A chlorhexidine acetate suppository raw material screening device, disclosed in publication number CN204564518U, includes a frame and a cylindrical sieve, with a fixed housing between the frame. The housing and the cylindrical sieve are truncated cone-shaped. This utility model provides a chlorhexidine acetate raw material screening device in which the screening cylinder maintains variable speed movement at all times, resulting in stronger relative movement of the raw material, improved utilization of the sieve surface, increased screening efficiency, and prevention of sieve clogging.

[0004] To address the issue of poor automatic cleaning of the screen surface due to the uniform speed motion and lack of vibration and speed variation during screening, existing technologies employ elliptical gear transmission. However, this method still generates significant amounts of dust during the screening process, which is difficult to collect and tends to disperse, thus impacting the screening environment for raw materials and reducing the efficiency of powder and waste collection.

[0020] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0021] 1. This invention provides a raw material pharmaceutical production screening structure that facilitates waste collection.

The auxiliary water-passing hose, water storage base, and multiple sets of fine mist nozzles are set up to spray the gas that is rotated and sprayed upward inside the dust-suppressing cylinder to suppress dust, further improving the uniformity of dust suppression, preventing the pharmaceutical dust generated during screening from being inhaled into the nasal cavity and lungs of workers, thus reducing the burden on the working environment.

The degree of automation is high, improving the overall effectiveness and practicality of the screening structure. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to embodiments: Example 1

[0038] like Figure 1-11 As shown, this invention provides a raw material pharmaceutical production screening structure that facilitates waste collection, including a fixed base 1 and a screening frame plate 11. The screening frame plate 11 is fixedly mounted on the upper end of the fixed base 1. A raw material pharmaceutical screening mechanism 2 is provided at one end and on the inner side of the screening frame plate 11. A dust treatment mechanism 3 is fixedly installed on the outer side of the screening frame plate 11. A classification and collection mechanism 4 is movably connected to one end of the screening frame plate 11. The raw material pharmaceutical screening mechanism 2 includes a driving propulsion unit and an auxiliary vibration unit, with the auxiliary vibration unit located on one side of the driving propulsion unit. The dust treatment mechanism 3 includes a dust suppression unit and an automatic anti-clogging unit. The blocking unit is located at the lower end of the dust collection unit; the classification and collection mechanism 4 includes a frame 41, a first receiving frame 42, a second receiving frame 43, and a pull rod 44. The first receiving frame 42 and the second receiving frame 43 are respectively fixedly installed on the inner side of the frame 41. The lower surface of the frame 41 is slidably connected to the inner wall of the preset groove at the upper end of the fixed base 1, and the pull rod 44 is fixedly installed on the outer side of one end of the frame 41. The driving and propulsion unit includes a first screening screen plate 211, a second screening screen plate 212, and a dual-shaft motor 214. The inner surfaces of one end of the first screening screen plate 211 and the second screening screen plate 212 are respectively rotatably connected to shafts 213, and the shafts 213... Both ends are fixedly connected to the inner wall of the screening frame plate 11. The dual-axis motor 214 is fixedly installed on the upper end of the fixed base 1. A connecting rod 215 is fixedly installed on the output shaft of the dual-axis motor 214, and cams 216 are fixedly installed on the outer surfaces of both ends of the connecting rod 215. By controlling the dual-axis motor 214 to turn on, its output shaft rotates, providing power for the rotation of the connecting rod 215, ensuring that the cams 216 and the connecting rod 215 rotate synchronously. The drive propulsion unit also includes a side plate 217 and a hinge block 218. A vertical plate 2171 is provided on the side of the side plate 217 away from the cam 216. The lower end of the vertical plate 2171 is slidably connected to the upper surface of the fixed base 1, and the upper end of the side plate 217 is fixedly installed with a connecting crossbar 2172. The outer surfaces of both ends of the connecting crossbar 2172 are slidably connected to the outer walls of both sides of the screening frame plate 11. Under the action of the reciprocating rotation of the cam 216, it reciprocates and pushes towards the side plate 217. During the pushing process, the angle between the hinge rod 2181 and the screening screen plate 1 211 and the screening screen plate 212 changes, realizing the reciprocating lifting and lowering of one end of the screening screen plate 1 211 and the screening screen plate 212, and realizing the automatic shaking of the two sets of screening screen plates. Example 2

[0039] like Figure 1-11As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the inner surface of the vertical plate 2171 is fixedly connected to one of the hinge blocks 218, the outer surface of the hinge block 218 is hinged with a hinge rod 2181, and the other end of the hinge rod 2181 is rotatably connected to a hinge block 2182 fixedly connected to the lower end of the screening screen plate 211. The auxiliary vibration unit includes a fixed connecting plate 221, which is fixedly installed on both outer surfaces of the screening frame plate 11, and the inner surface of the fixed connecting plate 221... The surface is fixedly connected with a telescopic sleeve 222 and an elastic spring 223, and the other end of the telescopic sleeve 222 and the elastic spring 223 are fixedly connected to the inner outer surface of the connecting crossbar 2172. While the vertical plate 2171 pushes the first sieve plate 211 and the second sieve plate 212 back and forth, the angle of the first hinge block 218 changes. During this process, the telescopic sleeve 222 is compressed and the elastic spring 223 undergoes elastic deformation, which further enhances the working efficiency and effectiveness of the two sets of sieve plates when sieving raw materials. Example 3

[0040] like Figure 1-11As shown, based on embodiments 1-2, the present invention provides a technical solution: Preferably, the dust collection unit includes a dust collection cylinder 311, which is fixedly installed on the upper end of the support rods fixedly connected to both sides of the screening frame plate 11. The inner cavity of the dust collection cylinder 311 is provided with a water storage tank 3111, and the lower end of the dust collection cylinder 311 is provided with a drain plate 3112. A water inlet pipe is connected through the outer surface of one side of the dust collection cylinder 311, and a miniature exhaust fan 312 is fixedly installed at the upper end of the dust collection cylinder 311. An air inlet cone 313 is fixedly connected to the input end of the micro exhaust fan 312, and a connecting air pipe 314 is fixedly connected to the output end of the micro exhaust fan 312. A conical rotating air pipe 315 is sealed to the lower end of the connecting air pipe 314. A guide plate 3151 is fixedly added to the outer surface of the conical rotating air pipe 315. A rotating seat 3152 is rotatably connected to the lower end of the conical rotating air pipe 315. An air jet bend 3153 and a hollow air outlet plate 3154 are sealed to the outer surface of the rotating seat 3152. The upper surface of unit 154 is evenly distributed with injection holes. When the micro exhaust fan 312 is activated, the dust generated during the external sieving process by the intake cone 313 is drawn in and stored inside the conical rotating air pipe 315 via the connecting air pipe 314. Through the array of jet bends 3153, the reaction force generated during jetting drives the rotating seat 3152 to rotate, propelling multiple hollow exhaust plates 3154 to rotate and spray air, achieving uniform jetting of dust-laden gas. The dust suppression unit also includes a water hose. 316. One end of the water hose 316 passes through the interior of the water storage tank 3111. A water storage base 317 is fixedly installed at the water outlet end of the water hose 316, and a fine mist nozzle 318 is fixedly connected to the water outlet end of the water storage base 317. The arrangement of the water hose 316, the water storage base 317 and the multiple sets of fine mist nozzles 318 helps to spray the gas that is rotated and rising inside the dust suppression cylinder 311 to suppress dust, further improving the uniformity of dust suppression and preventing the chemical dust generated during screening from being inhaled into the nose and lungs of the workers. Example 4

[0041] like Figure 1-11As shown, based on embodiments 1-3, the present invention provides a technical solution: Preferably, the automatic anti-clogging unit includes a dust collection box 321, a filter plate 322, and a micro motor 324. The filter plate 322 is movably embedded inside the dust collection box 321. The upper end of the dust collection box 321 is sealed and snapped into the lower end of the dust settling cylinder 311. A fixing clamp 323 is fixedly installed on the top surface of the inner cavity of the dust collection box 321. Fixing sleeves 3231 are fixedly installed on the outer surfaces of both ends of the fixing clamp 323. A telescopic cylinder 3232 is slidably connected to the inner surface of 231. A telescopic brush plate 3233, which is movably connected to the lower end of the sewage discharge base plate 3112, is fixedly connected to the end of the telescopic cylinder 3232 away from the fixed clamp 323. By adding a micro-dust collection box 321 at the lower end of the sewage discharge base plate 3112, wastewater generated from dust suppression is stored. Combined with the addition of the filter plate 322, solid-liquid separation of the wastewater is achieved, preventing the direct discharge of wastewater containing chemicals and thus avoiding environmental impact. A micro motor 324 is fixedly installed on one side of the micro-dust collection box 321. On the surface, a rotating rod 3241 is fixedly mounted on the output shaft of the micro motor 324. A bevel gear 3242 is fixedly mounted on the outer surface of the rotating rod 3241. Bevel gears 3243 mesh and rotate on both sides of the outer surfaces of the bevel gear 3242. A threaded rod 3244 is fixedly connected to the inner surface of the center of the bevel gear 3243, and the outer surface of the threaded rod 3244 is threadedly connected to the inner wall of one end of the telescopic cylinder 3232. By controlling the micro motor 324 to open, its output shaft rotates, driving the rotating rod 3241. The rotation causes the bevel gear 3242 and bevel gear 3243 to mesh and rotate, thereby driving the two sets of threaded rods 3244 to rotate synchronously. Under the dual limiting effect of the threaded adapter and the fixed sleeve 3231, the two sets of telescopic brushes 3233 reciprocate to scrape the bottom of the sewage discharge plate 3112 in opposite directions. Through this design, the blockage of the sewage discharge plate 3112 caused by long-term discharge of sewage from the bottom of the dust collection cylinder 311 is effectively avoided, and the bottom of the sewage discharge plate 3112 is automatically cleaned.

[0042] The working principle of this raw material screening structure, which facilitates waste collection, will be explained in detail below.

[0043] like Figure 1-11As shown, during operation, the raw material to be screened is first inverted above the screening screen plate 211. This allows for multi-stage screening by the screening screen plates 211 and 212. The raw materials of different finenesses are sequentially placed above the receiving frames 42 and 43. Then, the dual-shaft motor 214 is activated, causing the connecting rod 215 to rotate, which in turn causes the cam 216 to reciprocate. During rotation, the cam continuously impacts the side plate 217, thereby driving the connecting crossbar 2172 to advance the vertical plate 2171. The angle between the hinge rod 2181 and the screening screen plates 211 and 212 changes, achieving the reciprocating lifting and lowering of one end of the screening screen plates 211 and 212, thus automating the shaking of the two sets of screening screen plates. Furthermore, in the original... When the pharmaceutical materials are screened, a lot of pharmaceutical dust is generated. The micro exhaust fan 312 is activated to draw in external gas and dust, which enters the conical rotating air pipe 315 through the connecting air pipe 314. Through the arrangement of the array of jet bends 3153, the reaction force generated when the air is jetted drives the rotating seat 3152 to rotate, which in turn propels multiple hollow air outlet plates 3154 to rotate and jet. At this time, multiple sets of fine mist nozzles 318 spray the gas that is being jetted upward and rotating inside the dust settling cylinder 311 to reduce dust. In addition, by driving two sets of telescopic brush plates 3233 to reciprocate and scrape the bottom of the sewage discharge plate 3112 in opposite directions, this design effectively avoids the long-term discharge of sewage from the bottom of the dust settling cylinder 311, which would cause blockage of the sewage discharge plate 3112, and realizes the automated cleaning of the bottom of the sewage discharge plate 3112.

[0044] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
