Description

Technical Field

[0001] The invention relates to the field of drug mixing, in particular to a mixing device for producing methylbenzotriazole. Background Art

[0002] The production process of methylbenzotriazole requires precise and efficient mixing operations to ensure uniform reaction of raw materials, improve reaction efficiency, control reaction rate and avoid uneven reaction or material waste.

[0003] In the production process of methylbenzotriazole, solid particle raw materials mainly include benzotriazole precursor, methylation reagent, catalyst, etc.; liquid raw materials include solvents, acid-base solutions, methylation solvents, etc.; during the mixing process, solid particles and liquid raw materials need to be evenly dispersed to ensure the smooth progress of the reaction and efficient conversion.

[0004] In the current mixing process, solid raw materials and liquid raw materials are generally added to the mixing barrel together, but the solid raw materials are often not evenly distributed in the liquid, and thus are prone to form agglomerates, which not only hinders the full contact of the reactants, but may also cause oversaturation of the reactants or insufficient reaction in certain areas, thereby affecting the quality and consistency of the products. At the same time, the materials in the mixing barrel are prone to adhere to the barrel wall, especially in a high-viscosity liquid environment. These adhered materials are difficult to completely scrape off, resulting in low mixing efficiency. Traditional scraping devices may not be able to completely remove the adhered materials on the barrel wall, resulting in the failure of the materials in the local area to fully participate in the reaction, further aggravating the uneven mixing and affecting the overall mixing effect and reaction efficiency. Summary of the invention

[0005] In order to overcome the problems that when solid raw materials are added to the mixing barrel together with liquid raw materials, the solid raw materials are difficult to distribute evenly and are easy to agglomerate, which hinders the contact of reactants and leads to incomplete reaction. At the same time, the materials are easy to adhere to the barrel wall, especially in a high viscosity environment, and the traditional scraping device is difficult to remove, further reducing the shortcomings of mixing efficiency. Therefore, it is necessary to provide a mixing device for the production of methylbenzotriazole, which can effectively avoid the agglomeration phenomenon caused by a large amount of one-time addition by discharging solid raw materials intermittently and quantitatively; in addition, during the mixing process, the scraping device can comprehensively clean the material residues on the inner wall of the barrel, reduce material adhesion, and ensure that every corner of the mixing barrel can be fully stirred, thereby improving the uniformity and efficiency of mixing and avoiding the problems of insufficient reaction or material waste.

[0044] The two transmission assemblies 36 are respectively composed of two transmission pulleys and a transmission belt. The four transmission pulleys are respectively installed on the side away from each other between the output shafts of the two servo motors 35 and the two hollow rotating tubes 31, and a transmission belt is wound between the two transmission pulleys on the same side.

[0045] The feeding mechanism includes a charging hopper 41 installed on one side of the upper part of the bracket 1, a rotating joint 42 is provided at the outlet of the lower part of the charging hopper 41, a feeding inclined tube 43 is connected to the rotating joint 42, and passes through one of the hollow rotating tubes 31. The feeding inclined tube 43 is connected to the charging hopper 41 through the rotating joint 42, and the other end of the feeding inclined tube 43 is connected to the mixing cylinder 33. The feeding inclined tube 43 is connected to the mixing cylinder 33, and a feeding ball for quantitatively adding solid particle raw materials is provided at the lower part of the feeding inclined tube 43 through a bearing rotation. A valve body 44, a feeding gear 45 is installed on one side of the feed ball valve body 44, a fixing frame 46 is installed on the side of the bracket 1 away from the loading hopper 41, the fixing frame 46 passes through another hollow rotating tube 31, and a ring groove fixed plate 47 is installed on the fixing frame 46, and an annular groove is opened on the ring groove fixed plate 47, and an arcuate inner rack 48 and an arcuate outer rack 49 are respectively installed on the outer ring and inner ring of the annular groove on the ring groove fixed plate 47, and the feeding gear 45 will mesh with the arcuate inner rack 48 and the arcuate outer rack 49 respectively.

[0046] The feed ball valve body 44 is provided with a countersunk hole for temporarily storing solid particle raw materials.

[0047] The operator first starts the output shafts of the two servo motors 35 and rotates them 180 degrees and then stops. The output shafts of the two servo motors 35 drive the hollow rotating tube 31, the connecting frame 32, the mixing barrel 33, the discharge ball valve body 34, the feed inclined tube 43, the feed ball valve body 44 and the unloading gear 45 to rotate 180 degrees and then stop through the two transmission components 36. Initially, the countersunk hole of the feed ball valve body 44 is connected to the mixing barrel 33. During the rotation of the unloading gear 45, it meshes with the arc-shaped outer rack 49. Under the action of the arc-shaped outer rack 49, the unloading gear 45 will drive the feed ball valve body 44 to rotate 180 degrees and then stop. The countersunk hole is connected to the feed inclined tube 43; the operator turns the discharge ball valve body 34 and rotates it 180 degrees and stops. After the through hole on the discharge ball valve body 34 is connected to the mixing barrel 33, the operator loads an appropriate amount of liquid raw material into the mixing barrel 33 through the through hole on the discharge ball valve body 34, and then the operator turns the discharge ball valve body 34 and rotates it 180 degrees in the opposite direction and stops. The through hole on the discharge ball valve body 34 is not connected to the mixing barrel 33; then the operator loads an appropriate amount of solid particle raw material into the charging hopper 41, and the solid particle raw material in the charging hopper 41 enters the countersunk hole of the feed ball valve body 44 through the feed inclined tube 43; then start the two servo The output shaft of the motor 35 rotates, and the output shafts of the two servo motors 35 drive the hollow rotating tube 31, the connecting frame 32, the mixing barrel 33, the discharge ball valve body 34, the feed inclined tube 43, the feed ball valve body 44 and the unloading gear 45 to rotate through the two transmission components 36; during the rotation of the unloading gear 45, it meshes with the arc-shaped internal rack 48. Under the action of the arc-shaped internal rack 48, the unloading gear 45 will drive the feed ball valve body 44 to rotate 180 degrees in the opposite direction and then stop. The solid particle raw material in the countersunk hole of the feed ball valve body 44 can be discharged into the mixing barrel 33 and mixed with the liquid raw material. As the unloading gear 45 continues to rotate, the unloading gear 4 5 meshes with the arc-shaped outer rack 49 again. Under the action of the arc-shaped outer rack 49, the feeding gear 45 drives the feeding ball valve body 44 to rotate 180 degrees and then stop. The countersunk hole of the feeding ball valve body 44 is connected with the feeding inclined tube 43. The solid particle raw material in the charging hopper 41 enters the countersunk hole of the feeding ball valve body 44 through the feeding inclined tube 43 again. This is repeated, and the solid particle raw material can be intermittently and quantitatively discharged into the mixing barrel 33, ensuring that the contact time between the particles and the liquid is effectively distributed, so that the particles can be evenly distributed in the liquid, avoiding local oversaturation or uneven reaction caused by particle aggregation or accumulation;This not only improves the mixing effect, but also effectively avoids the problem of material waste or insufficient mixing caused by particle agglomeration. As the mixing barrel 33 rotates continuously, the solid particle raw materials are intermittently and quantitatively discharged into the mixing barrel 33, so that the liquid raw materials and the solid particle raw materials can be fully mixed. After the mixing is completed, the operator controls the mixing barrel 33 to rotate to the initial position and then stops, and then the operator turns the discharge ball valve body 34 to rotate 180 degrees and then stops. After the through hole on the discharge ball valve body 34 is connected with the mixing barrel 33, the operator pressurizes the mixing barrel 33 through the ventilation check valve 341, and the mixed raw materials can be discharged from the mixing barrel 33 through the through hole on the discharge ball valve body 34. ;

[0048] Embodiment 2: Based on embodiment 1, Figure 1-Figure 14 As shown, it also includes a mixing mechanism arranged on the fixed disk 2 and the mixing barrel 33, the mixing mechanism is used to mix the raw materials, and the mixing mechanism includes a hollow rotating shaft 51 rotatably mounted on the mixing barrel 33 through a bearing, both ends of the hollow rotating shaft 51 pass through both sides of the mixing barrel 33, and mixing blades 52 for mixing the raw materials are evenly installed on the hollow rotating shaft 51 at intervals, and the mixing blades 52 are located in the mixing barrel 33, driving gears 53 fixedly mounted on both ends of the hollow rotating shaft 51, and inner gear rings 54 respectively fixedly mounted on the two fixed disks 2, and the driving gear 53 on the same side is meshed with the inner gear ring 54 on the same side.

[0049] The two mixing blades 52 are respectively in contact with the two side walls of the mixing barrel 33 .

[0050] The side scraping mechanism is also included, which is installed on the fixed disk 2 and the hollow rotating shaft 51. The side scraping mechanism is used to scrape off the raw materials stuck on the inner wall of the mixing drum 33. The side scraping mechanism includes a sliding rod 61 which is slidably arranged on the hollow rotating shaft 51. The sliding rod 61 will slide along the hollow rotating shaft 51. A plurality of slots 62 are evenly spaced apart on the hollow rotating shaft 51.

Each side scraping blade 63 passes through each slot 62 respectively. A side of each side scraping blade 63 away from the sliding rod 61 is in contact with the curved surface in the mixing drum 33. A ball 64 is rotatably embedded in both ends of the sliding rod 61. A corrugated frame 65 is respectively installed on the side of the two fixed disks 2 close to each other. Two balls 64 are in contact with the two corrugated frames 65 respectively.

[0051] When the mixing drum 33 rotates, the hollow shaft 51, the mixing blades 52 and the two driving gears 53 are driven to rotate. Under the action of the two inner gear rings 54, the two driving gears 53 will rotate. The two driving gears 53 drive the hollow shaft 51 and the mixing blades 52 to rotate. The mixing blades 52 can separate and mix the liquid raw materials and the solid particle raw materials in the mixing drum 33. The two mixing blades 52 scrape the two side walls in the mixing drum 33 respectively, which effectively reduces the dead corners caused by material adhesion in the mixing drum 33, ensures that the materials in each corner can be fully stirred and mixed, and avoids the phenomenon of local excessive concentration or uneven distribution of raw materials due to insufficient stirring of materials in certain areas; by scraping the two side walls, the mixing blades 52 can not only reduce the accumulation of raw materials, but also effectively improve the mixing efficiency, ensuring that the mixing process is more uniform and stable.

[0052] The mixing barrel 33 drives the hollow rotating tube 31, the sliding rod 61, the side scraping blades 63 and the ball bearings 64 to rotate. The sliding rod 61 and the side scraping blades 63 continuously move back and forth under the action of the two corrugated frames 65. The two ball bearings 64 play a guiding role. The side scraping blades 63 can perform comprehensive scraping on the curved surface of the inner wall of the mixing barrel 33. The side scraping blades 63 can move accurately along the curved surface to ensure that no dead corners are missed, thereby avoiding the accumulation and adhesion of raw materials on the inner wall of the mixing barrel 33 to the greatest extent; the side scraping blades 63 are not only limited to the straight part of the barrel wall, but also include all curved surface areas. The side scraping blades 63 can completely remove any adhered materials that may appear on the inner wall through continuous reciprocating motion, ensuring that the materials remain in a flowing state throughout the mixing process, avoiding uneven mixing or agglomeration caused by local accumulation.

A corrugated groove 77 is opened on the annular groove fixed plate 47, and the roller 76 is located in the corrugated groove 77.

[0054] The rotation of the feed inclined tube 43 and the feed ball valve body 44 drives the circular plate 71, the scraper frame 72, the transverse gear 73, the transverse rack 74, the sliding frame 75 and the roller 76 to rotate. The roller 76 will reciprocate when rotating along the corrugated groove 77. The roller 76 drives the sliding frame 75 and the transverse rack 74 to reciprocate. The transverse rack 74 drives the transverse gear 73 and the scraper frame 72 to rotate forward and reversely.
