Description

Technical Field

[0001] The invention relates to the field of mixing, and more particularly to a sarafloxacin hydrochloride raw material mixing device. Background Art

[0002] In the pharmaceutical production process of sarafloxacin hydrochloride raw materials (including a multiphase mixture of granules and powders), mixing uniformity is a key indicator that directly affects the consistency of drug ingredients and product quality. Traditional horizontal mixing equipment generally uses unidirectional rotating blades or spiral ribbon structures.

[0003] In the preparation process of sarafloxacin hydrochloride, horizontal mixers or fluidized bed mixers are generally used in the raw material mixing process.

[0019] The present invention realizes three-dimensional dynamic mixing of raw materials through the innovative spreading mechanism design, significantly improving the mixing uniformity. When the mixing plate drives the material holding plate to rotate to the bottom, the concave cavity formed by the elastic film and the material holding plate can accurately grab the raw material particles deposited on the bottom layer, effectively breaking the common stratification phenomenon of traditional mixing equipment. When rotating to a set angle, the coil spring drives the elastic film to produce deformation rebound, and evenly scatters the bottom small particle raw materials to the surface with controllable force, forming a "bottom layer grabbing-surface layer covering" cyclic operation mode. With the air pressure regulating system of the air storage bag, the single scattering amount can be adjusted in real time according to the mixing process to ensure that raw materials of different particle sizes are fully contacted.

[0020] The synergy between the material control mechanism and the spreading mechanism greatly improves the process flexibility of the equipment. The air path control system composed of the air storage bag can accurately control the gripping force of the elastic film and the rebound potential energy of the coil spring by adjusting the air pressure parameters, and achieve 0.5-5kg / batch feed amount adjustment. This flexible control mechanism enables the equipment to handle highly fluid micro-powder raw materials and meet the mixing needs of sticky particles. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The air storage bag 39 is connected to the air circuit of the material control mechanism 2, and the raw material feeding amount is adjusted in real time through the change of air pressure;

[0036] When the mixing and dispensing plate 17 drives the material holding plate 31 to rotate upward from the bottom of the cylinder, the elastic film 32 and the material holding plate 31 form a concave cavity to grab the bottom layer of raw materials.

[0039] A swing plate 36 is fixedly provided on the rotating column head of the material holding plate 31 located inside the control rotating cylinder 33, a magnetic sheet 37 is fixedly provided on the side of the swing plate 36 close to the magnetic block chamber 301, and an arc-shaped extrusion sheet 35 is fixedly provided on the side of the swing plate 36 away from the magnetic block chamber 301. The magnetism of the magnetic sheet 37 and the magnetism of the magnetic block 2 303 repel each other.

[0040] The inner wall of the rotating plate chamber 38 is fixedly provided with three identical and parallelly distributed air storage bags 39 , each of which is provided with an air outlet hose at its output end, and the air outlet ends of the three air outlet hoses are all passed through the interior of the mixing and shifting plate 17 and connected to the material control mechanism 2 .

[0041] The air outlet hose of the first air storage bag 39 near the pendulum plate 36 is provided with two air outlet ends, one of which is provided with an expansion bag 43 fixed on the side ridge of the mixing and material prying plate 17, and the surface of the expansion bag 43 in the expanded state protrudes from the side edge of the mixing and material prying plate 17, and the outside of the expansion bag 43 is provided with a push-turn buckle 42 rotatably connected to the mixing and material prying plate 17, and the inside of the mixing inner cylinder 14 is provided with a force groove 41, and the positions of the force groove 41 and the push-turn buckle 42 are aligned with each other, and the outer ridges at both ends of the mixing inner cylinder 14 are rotatably provided with a plurality of rotating beads 19.

[0042] The material control mechanism 2 includes a cartridge cover 21 located at the connecting end of the horizontal mixing barrel 11 and the temporary storage chamber 12, a sinking plate box 22 is fixedly arranged below the cartridge cover 21, an inverted triangular lifting plate 26 is slidably arranged inside the sinking plate box 22, and a material blocking plate 25 that passes through the cartridge cover 21 is fixedly arranged above the lifting plate 26.

[0043] Guide columns 27 are passed through both ends of the lifting plate 26, and the material blocking plate 25 slides along the guide columns 27 through the lifting plate 26. A plurality of elastic bands 28 are fixedly provided on the lower side of the lifting plate 26, and the bottoms of the plurality of elastic bands 28 are fixedly connected to the inner bottom wall of the sinking plate box 22.

[0044] A sliding block 29 slidably connected to the sinking plate box 22 is provided on the other side below the lifting plate 26. An electric push rod 23 is fixedly provided on the sliding block 29 and one side of the sinking plate box 22 close to the sliding block 29. The output end of the electric push rod 23 passes through the sinking plate box 22 and is fixedly connected to the sliding block 29.

[0045] The control end of the electric push rod 23 is connected to three electromagnetic switches 24 through wires. The three electromagnetic switches 24 are fixed to the inner wall of the temporary storage chamber 12. Three magnetic balls 52 that match the three electromagnetic switches 24 are rotatably arranged inside the top of the blade of the feeding screw 18. A telescopic air column 51 is fixedly arranged on one side of the three magnetic balls 52. The three telescopic air columns 51 are respectively connected to the air outlet hoses of the three air storage bags 39.

[0046] Particles and powders of different diameters are added into the temporary storage chamber 12 through the feeding port 13. The raw material particles and powders are accumulated in the temporary storage chamber 12, waiting to be pushed by the feeding screw 18. The feeding screw 18 starts to work, pushing the raw material particles and powders in the temporary storage chamber 12 toward the mixing inner cylinder 14. After the raw material particles and powders enter the mixing inner cylinder 14, they are acted upon by the mixing and shifting plate 17, and begin to move outward along the inner wall of the mixing inner cylinder 14, and are finally discharged from the outlet.

[0047] like Figure 8 , Fig. 9 and Fig.10 As shown, when the raw material particles and powder enter the mixing inner cylinder 14 from the temporary storage chamber 12, the raw material particles and powder accumulated in the middle and bottom layers of the mixing inner cylinder 14 collide with the material holding plate 31, and the material holding plate 31 is hit by the raw material particles and powder to rotate in the opposite direction to the mixing and shifting plate 17, and stores a part of the raw material particles and powder. When the material holding plate 31 rotates 270° with the mixing and shifting plate 17, the raw material particles and powder stored in the elastic film 32 are scattered and sprinkled on the middle layer of the mixing inner cylinder 14 with the inertia of the mixing and shifting plate 17 through the assistance of the shifting piece of the control rotating cylinder 33, ensuring that the raw material particles and powder are evenly spread at the bottom of the mixing inner cylinder 14, reducing the deposition of powder under the granular material and large particles floating on the surface.

[0048] When the mixing paddle plate 17 rotates to the bottom of the mixing inner cylinder 14, a large amount of raw material particles and powders, under the action of the high-speed rotating mixing paddle plate 17, part of which hits the closed material receiving plate 31, and the other part hits the mixing paddle plate 17, and are pushed by the mixing paddle plate 17 to slide along the inner wall of the mixing inner cylinder 14. The raw material particles and powders stored in the material receiving plate 31 and the elastic film 32 rotate with the mixing paddle plate 17 and will not contact the inner wall of the mixing inner cylinder 14. This is beneficial to reduce the accumulation of too thick raw material particles and powders passing over the inner wall of the mixing inner cylinder 14, and has the effect of evenly distributing the materials, so that the raw material particles and powders can be mixed more evenly.

[0049] The material is quantitatively fed into the temporary storage chamber 12 at a rate of 500 kg / h through the feeding port 13, and the feeding propeller 18 pushes the raw materials to the mixing inner cylinder 14 at a speed of 30 rpm. The mixing inner cylinder 14 rotates in the same direction, and the protruding prisms on its inner wall cause the raw materials to produce turbulent motion, which increases the initial mixing efficiency by about 40%.

[0050] When the raw material particles and powder stored in the material holding plate 31 and the elastic film 32 rotate 270°, under the dual action of gravity and the magnetic block 1 302, the multiple magnetic blocks 2 303 are pushed to slide quickly to the end away from the magnetic block 1 302. At this time, the repulsive force of the multiple magnetic blocks 2 303 acts on the magnetic sheet 37, pushing the magnetic sheet 37 to move in the opposite direction. In addition, the return elastic force of the coil spring 34 drives the swing plate 36 to rotate along the rotation direction of the mixing and feeding plate 17 under the dual action of the two. The material holding plate 31 is driven to rotate through the swing plate 36, so that the raw material particles and powder stored in the material holding plate 31 and the elastic film 32 can be broken up with the inertia of the mixing and feeding plate 17 in the rotation direction, and scattered in the mixing inner cylinder 14. The evenly distributed raw material particles and powder can contact the mixing inner cylinder 14 more fully, thereby improving the mixing and stirring efficiency.

[0051] When the mixing plate 17 drives the material holding plate 31 to rotate upward from the bottom at 18rpm, the elastic film 32 and the material holding plate 31 form a concave cavity with a depth of 8-12 mm, and the single grab amount reaches 50-80 g of the bottom layer of raw materials. When rotating to the 270° position, the coil spring 34 releases the preload force, and the elastic coefficient is 12N / mm. Combined with the 0.8 N repulsive force between the magnetic block 1 302 and the magnetic block 2 303, the material holding plate 31 completes a 60° rapid flip in 0.3 seconds, and the raw materials are thrown to the surface at an initial speed of 3-5 m / s, achieving a 65% increase in the interlayer permeability of particles and powders.

[0052] The more raw material particles and powder are accumulated at the bottom of the mixing inner cylinder 14, the greater the angle of rotation of the material holding plate 31 is, and the more raw material particles and powder are stored.

[0053] When raw material particles and powder are accumulated at the bottom of the mixing inner cylinder 14, the swing plate 36 rotates as the material holding plate 31 is opened. The more raw material particles and powder are accumulated, the greater the swing plate 36 rotates, so that the extrusion sheet 35 is pulled out longer, and the more the air storage bag 39 is squeezed;

[0054] When the extrusion sheet 35 squeezes the first air storage bag 39, the air in the first air storage bag 39 flows into the expansion bag 43 through the air outlet hose, so that the expansion bag 43 expands, and the push-turn buckle 42 is propped up by the expansion of the expansion bag 43. After that, when the push-turn buckle 42 rotates to the position of the force-bearing groove 41, the expansion bag 43 instantly expands and props up the push-turn buckle 42, so that the push-turn buckle 42 is stuck in the force-bearing groove 41, and the mixing inner cylinder 14 is driven to rotate 90° through the mixing and diverting plate 17;

[0055] When a large amount of raw material particles and powder are accumulated at the bottom of the mixing inner cylinder 14, it indicates that there may be a large amount of raw materials in the mixing inner cylinder 14. Therefore, by rotating the mixing inner cylinder 14 and changing the position of the bottom of the mixing inner cylinder 14, the powder at the bottom of the raw materials can be driven to rise with the rotation of the mixing inner cylinder 14 and be spread again.

[0056] When a large amount of raw material particles and powder are accumulated at the bottom of the mixing inner cylinder 14, the longer the squeeze sheet 35 is pulled out, the more the air storage bags 39 are squeezed, and the air in the three air storage bags 39 flows into the telescopic air column 51 from the air outlet hose to expand and extend it. The extension of the telescopic air column 51 pushes the magnetic ball 52 to rotate, so that the side of the magnetic ball 52 with the magnet faces the outer circle position of the feeding screw 18. There are several air storage bags 39 that are squeezed, and there are several telescopic air columns 51 that expand. After that, when the end of the feeding screw 18 with the magnetic ball 52 rotates to the position of the three electromagnetic switches 24, at the moment when the magnetic ball 52 approaches the electromagnetic switch 24, the electromagnetic switch 24 controls the electric push rod 23 to push the sliding block 29 to slide, thereby pushing the baffle plate 25 to rise through the sliding block 29. The higher the baffle plate 25 rises, the fewer raw material particles and powder enter the mixing inner cylinder 14.

[0057] The three electromagnetic switches 24 respectively control different extension distances of the electric push rod 23. When a large amount of raw material particles and powder are accumulated at the bottom of the mixing inner cylinder 14, the amount entering the mixing inner cylinder 14 can be controlled according to the accumulated amount.

[0058] The embodiments of the present invention are described above, but the present invention is not limited to the above-mentioned specific implementation modes. The above-mentioned specific implementation modes are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, which are all within the protection of the present embodiment.
