Description

Technical Field

[0001] The invention belongs to the technical field of pharmaceutical processing, and in particular relates to a stirring and mixing device for processing pharmaceutical intermediates with automatic feeding. Background Art

[0002] Pharmaceutical intermediates refer to chemical substances used to synthesize the final active ingredients of drugs during the process of drug development and production. These intermediates usually have complex chemical structures and reactivity, and require multiple steps of synthesis to obtain the final active ingredients of drugs. The mixing of pharmaceutical intermediates refers to mixing different intermediates in a certain proportion to achieve the synthesis and production of drugs.

[0003] However, the existing automatic feeding stirring and mixing devices for pharmaceutical intermediate processing often have some problems in actual use: in the mixing process of existing pharmaceutical intermediates, the stirring rod of the mixing device used for stirring the pharmaceutical intermediates is often fixed and integrated with the rotating shaft, and the stirring rod is usually cylindrical. During the stirring process, the accumulated pharmaceutical intermediates and the mixed liquid are only pushed by the surface of the arc, so that the positions of the pharmaceutical intermediates and the mixed liquid are changed, so that they are mixed, resulting in that the raw materials cannot be fully mixed during the mixing process, and a long stirring time is required to complete the stirring work, and the mixing efficiency is low; secondly, in the prior art, when mixing pharmaceutical intermediates, the pharmaceutical intermediates and the mixed liquid are usually directly added to the mixing box for stirring. At this time, the mixing ratio cannot be controlled, which is very likely to cause incomplete mixing and excessive waste of the mixed liquid during the mixing process, which affects the mixing effect and is also prone to cause some unnecessary waste.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The present invention starts a first driving motor, which drives the main shaft to rotate. The rotation of the main shaft drives the sun gear to rotate. The rotation of the sun gear drives multiple planetary gears to rotate. The rotation of the planetary gears drives the first rotating shaft to rotate. The rotation of the first rotating shaft drives the first bevel gear to rotate. The rotation of the first bevel gear drives the second bevel gear to rotate. The rotation of the second bevel gear drives the second rotating shaft to rotate. The rotation of the second rotating shaft drives the curved arc stirring rod to rotate. Since multiple curved arc stirring rods are arranged inside, the multiple curved arc stirring rods can be divided into three groups. When the three groups of curved arc stirring rods rotate, three independent stirring vortices are generated in the pharmaceutical intermediate inside the mixing chamber. The three independent stirring vortices will rotate during the rotation process. The curved stirring rod has an arc-shaped surface, which can increase the pushing area, improve the stirring rate, and improve the stirring effect. At the same time, when the pharmaceutical intermediate enters the mixing chamber, it is separated from the mixed liquid.

Compared with the cylindrical stirring rod in the prior art, it can mix it better, and its mixing efficiency is further improved.

[0015] 2. The present invention starts the second drive motor and the air pump. The second drive motor starts to drive the third rotating shaft to rotate. The rotation of the third rotating shaft drives the metering wheel to rotate. The rotation of the metering wheel will drive the pharmaceutical intermediate that falls into the groove on the surface of the metering wheel through the feeding funnel to rotate, so that it falls into the interior of the mixing chamber from below. At the same time, the air pump starts to inflate and pressurize the interior of the air storage chamber, thereby pushing the movable block to move to one side. The movement of the movable block drives the piston to move forward. The forward movement of the piston drives the water flow to move, thereby squeezing the three-way pipe to open the three-way pipe, and the mixed liquid flows out from the bottom of the three-way pipe. At this time, it is only necessary to control the speed of the second drive motor and the piston advancement rate to achieve quantitative control and control the mixing ratio. In the mixing process, incomplete mixing and excessive waste of mixed liquid are effectively avoided, thereby improving the mixing effect and avoiding some unnecessary waste.

[0016] 3. The present invention pressurizes the water flow through the water outlet nozzle, flushes out from the water outlet, cleans the curved arc stirring rod, and realizes self-cleaning. During the process of water flow rushing out, the water flow will move along the inner arc surface of the curved arc stirring rod, thereby generating a smaller vortex on the inner arc surface, so as to better remove the adhesions attached to the surface of the curved arc stirring rod, and at the same time, it can clean the outer surface of the other curved arc stirring rod, thereby cleaning the entire stirring rod and improving the cleaning effect.

A plurality of bearing sleeves 9 are rotatably connected to the outside of the fixed sleeve 8, and a first bevel gear 10 is arranged inside the plurality of bearing sleeves 9. The first bevel gear 10 is fixedly connected to the outside of the first rotating shaft 801, and a plurality of second bevel gears 11 are meshed and connected to the outside of the first bevel gear 10. A second rotating shaft 12 is fixedly connected to one side of the plurality of second bevel gears 11, and a plurality of curved stirring rods 13 are fixedly connected to the outside of the second rotating shaft 12, and a cleaning component is arranged inside the curved stirring rod 13. A solid quantitative feeding component is arranged on the top of the mixing tank body 1, and a liquid quantitative feeding component is arranged on one side of the top of the mixing tank body 1. After the pharmaceutical intermediate and the mixed liquid enter the mixing chamber 2, the first drive motor 3 is started, and the first drive motor 3 starts to drive the main shaft 4 to rotate The main shaft 4 rotates and drives, and at the same time, the main shaft 4 rotates and drives the sun gear 6 to rotate, the sun gear 6 rotates and drives multiple planetary gears 7 to rotate, the planetary gears 7 rotate and drive the first shaft 801 to rotate, the first shaft 801 rotates and drives the first bevel gear 10 to rotate, the first bevel gear 10 rotates and drives the second bevel gear 11 to rotate, the second bevel gear 11 rotates and drives the second shaft 12 to rotate, the second shaft 12 rotates and drives the curved stirring rod 13 to rotate. Since multiple curved stirring rods 13 are arranged inside, the multiple curved stirring rods 13 can be divided into 3 groups. When the three groups of curved stirring rods rotate, the pharmaceutical intermediates in the mixing chamber 2 will generate three independent stirring vortices, and the three independent stirring vortices will affect each other during the rotation process. The curved stirring rod 13 has an arc shape, which can increase the pushing area through the arc surface during the stirring process, thereby increasing the stirring rate and the stirring effect.

[0027] Among them, the solid quantitative feeding component includes a support block 17, the support block 17 is fixedly connected to one side of the top of the mixing tank body 1, the top of the support block 17 is fixedly connected to a second drive motor 18, a feeding funnel 19 is arranged on one side of the second drive motor 18, the feeding funnel 19 is fixedly connected to the mixing tank body 1, the output end of the second drive motor 18 is fixedly connected to a third rotating shaft 20, the third rotating shaft 20 extends to the inside of the feeding funnel 19 and is rotatably connected to the feeding funnel 19, a quantitative wheel 21 is arranged inside the feeding funnel 19, the quantitative wheel 21 is fixedly connected to the third rotating shaft 20, and a gap is left between the quantitative wheel 21 and the feeding funnel 19, and the liquid quantitative feeding component includes an air pump 22, and the air pump 22 is fixedly connected to the mixing tank body. On one side of the top of the body 1, an air pump 22 is fixedly connected to an air intake pipe 23, and one side of the air intake pipe 23 is fixedly connected to an air storage chamber 24. Two limit blocks 25 are fixedly connected to the bottom of the air storage chamber 24, and a movable block 26 is slidably connected between the two limit blocks 25. A three-way pipe 27 is provided on one side of the air storage chamber 24, and a piston 28 is fixedly connected to one side of the movable block 26. The piston 28 is slidably connected to the horizontal part of the three-way pipe 27. The upper and lower ends of the three-way pipe 27 are respectively fixedly connected to a one-way valve 29. By putting the pharmaceutical intermediate and the mixed liquid into the feeding funnel 19 and the three-way pipe 27 respectively, the outside of the three-way pipe 27 can be connected to an external pipe to add the mixed liquid, and the mixed liquid is discharged from the three-way pipe 27. The end enters the three-way pipe 27 through the upper one-way valve body 29, and fills the three-way pipe 27 after entering. In the process of the mixed liquid filling the three-way pipe 27, since the pressure at this time is not enough to conduct the bottom one-way valve, the piston 28 will be pushed out to the left by pressure after filling. When the piston 28 is pushed out to the left to move the movable block 26 to the side of the fitting limit block 25, the quantitative addition of the mixed liquid is completed. After the addition is completed, the second drive motor 18 and the air pump 22 are started. The second drive motor 18 starts to drive the third rotating shaft 20 to rotate. The rotation of the third rotating shaft 20 drives the quantitative wheel 21 to rotate. The rotation of the quantitative wheel 21 will drive the quantitative wheel 21 to fall into the groove on the surface of the quantitative wheel 21 through the feeding funnel 19. The pharmaceutical intermediate rotates and falls into the mixing chamber 2 from below. At the same time, the air pump 22 starts to inflate and pressurize the air storage chamber 24, thereby pushing the movable block 26 to move to one side. The movement of the movable block 26 pushes the piston 28 forward. The movement of the piston 28 pushes the water flow to move, thereby squeezing the three-way pipe 27 to open the three-way pipe 27, and the mixed liquid flows out from the bottom of the three-way pipe 27. At this time, it is only necessary to control the speed of the second drive motor 18 and the advancement rate of the piston 28 to achieve quantitative control and control the mixing ratio. In the mixing process, incomplete mixing and excessive waste of the mixed liquid are effectively avoided, thereby improving the mixing effect and avoiding some unnecessary waste.

The feed funnel 19 and the support block 17 both extend to the interior of the mixing tank body 1, and the support block 17 and the feed funnel 19 are staggered with the fixed sleeve 8. The bottom of the through groove is arranged corresponding to the bottom of the mixing chamber 2, so that the discharge of materials and water can be unobstructed and retained inside. The staggered arrangement can prevent each other from affecting the use during the working process.

[0029] Among them, the water spray outlet 15 corresponds to the curved part of the curved stirring rod 13, and the corresponding angle between the water spray outlet 15 and the curved stirring rod 13 is 35°. The water spray outlet 15 corresponds to the curved part of the curved stirring rod 13, which can make the water flow move better along the curved surface of the curved stirring rod 13 to form a vortex, thereby improving the cleaning effect.

[0030] Working principle:

[0031] The pharmaceutical intermediate and the mixed liquid are placed in the feed funnel 19 and the three-way pipe 27 respectively. The outside of the three-way pipe 27 can be connected to an external pipe to add the mixed liquid. The mixed liquid enters the three-way pipe 27 from the upper end of the three-way pipe 27 through the upper one-way valve 29. After entering the interior, it will fill the three-way pipe 27. In the process of the mixed liquid filling the three-way pipe 27, since the pressure at this time is not enough to conduct the bottom one-way valve, the piston 28 will be pushed out to the left by pressure after filling. When the piston 28 is pushed out to the left to make the movable block 26 move to the side of the fitting limit block 25, the quantitative addition of the mixed liquid is completed. After the addition is completed, the second drive motor 18 and the air pump 22 are started. The second drive motor 18 starts to drive the third rotating shaft 20 to rotate, and the rotation of the third rotating shaft 20 drives the quantitative wheel 21 to rotate. The rotation of the metering wheel 21 will drive the pharmaceutical intermediate that has passed through the feed funnel 19 and fallen into the groove on the surface of the metering wheel 21 to rotate, thereby falling into the interior of the mixing chamber 2 from below. At the same time, the air pump 22 is started to inflate and pressurize the interior of the air storage chamber 24, thereby pushing the movable block 26 to move to one side, and the movement of the movable block 26 pushes the piston 28 to move forward, and the forward movement of the piston 28 pushes the water flow to move, thereby squeezing the three-way pipe 27 to open the three-way pipe 27, and the mixed liquid flows out from the bottom of the three-way pipe 27. At this time, it is only necessary to control the speed of the second drive motor 18 and the advancement rate of the piston 28 to achieve quantitative control and control the mixing ratio. In the mixing process, the situation of incomplete mixing and excessive waste of the mixed liquid is effectively avoided, thereby improving the mixing effect and avoiding some unnecessary waste;

[0032] After the pharmaceutical intermediate and the mixed liquid enter the mixing chamber 2, the first drive motor 3 is started, and the first drive motor 3 starts to drive the main shaft 4 to rotate, the rotation of the main shaft 4 drives the sun gear 6 to rotate, the rotation of the sun gear 6 drives the multiple planetary gears 7 to rotate, the rotation of the planetary gear 7 drives the first rotating shaft 801 to rotate, the rotation of the first rotating shaft 801 drives the first bevel gear 10 to rotate, the rotation of the first bevel gear 10 drives the second bevel gear 11 to rotate, the rotation of the second bevel gear 11 drives the second rotating shaft 12 to rotate, the rotation of the second rotating shaft 12 drives the curved stirring rod 13 to rotate, and since a plurality of curved stirring rods 13 are arranged inside, the plurality of curved stirring rods 13 can be divided into three groups. When the three groups of curved stirring rods rotate, the pharmaceutical intermediate inside the mixing chamber 2 will produce three independent The three independent vortices will affect each other during the rotation process to form a more complex fluid motion. This interaction helps to break the agglomeration of solid particles and make them better dispersed in the liquid, thereby improving the stirring effect. At the same time, due to the arc setting of the curved stirring rod 13, the curved stirring rod 13 can increase the pushing area through the curved surface during the stirring process, thereby improving the stirring rate and the stirring effect. At the same time, when the pharmaceutical intermediate enters the mixing chamber 2 and is separated from the mixed liquid, the curved stirring rod 13 can clamp the pharmaceutical intermediate into the arc through the arc during the stirring process, and bring the pharmaceutical intermediate into the mixed liquid part through rotation. Compared with the cylindrical stirring rod in the prior art, it can be better mixed, and its mixing efficiency is further improved.

[0033] After the mixing is completed, the water flows out from the water outlet 15 through the pressurized water outlet nozzle 16 to clean the curved stirring rod 13, thereby realizing self-cleaning. During the process of the water flowing out, the water flows along the inner arc surface of the curved stirring rod 13, thereby generating a smaller vortex on the inner arc surface, which can better remove the adhesions attached to the surface of the curved stirring rod 13, and at the same time can clean the outer surface of the other curved stirring rod 13, thereby cleaning the entire stirring rod and improving the cleaning effect.
