Description

Technical Field

[0001] This utility model belongs to the field of azelaic acid gel production technology, and specifically relates to an azelaic acid gel production device. Background Technology

[0002] During the production of azelaic acid gel, a concentration tank is used to heat, mix, and concentrate various raw material liquids to form a gel-like substance, which is then filtered and discharged from the concentration tank.

[0003] In modern azelaic acid gel production equipment, since azelaic acid raw materials often exist in crystalline form, if they are directly added to the mixing system, coarse particles and fine powders will mix. During the stirring and dissolving stage, the fine powders will quickly disperse and dissolve, while the coarse particles will take longer to dissolve completely. This not only prolongs the overall mixing cycle, but also easily leads to particle agglomeration due to insufficient local dissolution, resulting in small crystals visible to the naked eye in the gel, thus affecting the smoothness when applied.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In this invention, the azelaic acid crystal raw material is continuously fed to the feeding section using a conveying mechanism. The crystals then enter the processing section, where the first drive motor starts, rotating the driven crushing roller. This roller, in conjunction with the fixed crushing roller, continuously crushes the crystals. Regardless of whether the crushed crystals are qualified, they are filtered through a screening screen below. Qualified crystals enter the mixing zone inside the tank, while larger, unqualified crystals roll down naturally due to the tilt angle of the screening screen and the cooperation of the return springs and movable shafts connected to its ends, and are guided by the guide plate to the bottom of the bucket conveyor frame. At this point, the second drive motor is started. Driven by a set of synchronous belts and two synchronous pulleys, the upper section of the conveyor shaft inside the conveyor frame will rotate. Since there is a conveyor belt around the upper section of the conveyor shaft, the lower section of the conveyor shaft will also move accordingly. The conveyor belt will work with the two conveyor shafts to drive the surrounding hoppers to circulate. When the hopper moves to the bottom of the bucket conveyor frame, it will carry the unqualified crystals upwards until it passes the discharge rack and is guided back to the feeding section for secondary processing. This avoids the situation where unqualified crystals are left unattended and need to be taken out by personnel for auxiliary processing. It is convenient and practical to use.

[0018] After the crystals of this invention are crushed to a qualified state, they will be mixed with the required liquid in the tank. The stirring rods around the transmission rod, together with multiple cross-fixed connecting rods, can increase the mixing area of ​​the materials and improve the shearing force on the materials.

[0026] This specific embodiment is an azelaic acid gel production device, the structural schematic diagram of which is shown below. Figures 1 to 4As shown, the device includes a tank body 1. A pretreatment mechanism 2 is assembled on the top and one side of the tank body 1, and a mixing mechanism 3 is installed on the top and inside of the tank body 1. The pretreatment mechanism 2 includes a feeding section 21, which is located on the top side of the tank body 1. A processing section 22 is connected to the bottom end of the feeding section 21. A crushing assembly 23 is provided inside and below the processing section 22. The crushing assembly 23 includes a material collection frame 231, which is fixed to the bottom end of the feeding section 21. A driven crushing roller 232 is installed on one side of the middle part of the processing section 22, and a first drive motor 233 is installed at one end of the driven crushing roller 232. A fixed crushing roller 234 is fixed on the other side of the processing section 22, and a fixed frame 235 is fixed at the bottom of one side of the processing section 22. A return spring 236 is provided on the lower inner side of the fixed frame 235. The top of the return spring 236 is connected to one end of the screening frame 237. A movable shaft 238 is provided in the middle of the other end of the screening frame 237. A guide plate 239 is provided on one side of the tank body 1 opposite to the end of the screening frame 237. The screening frame 237 is elastically connected by the return spring 236 and the movable shaft 238. A reciprocating reflux assembly 24 is installed on the outer side of the tank body 1. The reciprocating reflux assembly 24 includes a bucket conveyor frame 241, which is fixedly installed on the upper side of the tank body 1. A conveyor shaft 242 is installed in the middle of the upper and lower parts of the bucket conveyor frame 241, and a conveyor belt 243 is sleeved around the periphery of the two conveyor shafts 242. A support frame 244 is fixedly mounted on one side of the upper section of the bucket conveyor frame 241, and a second drive motor 245 is mounted above the support frame 244. Synchronous pulleys 246 are fixedly mounted around the output end of the second drive motor 245 and a section of one of the conveyor shafts 242. Synchronous belts 247 are fitted around the periphery of the two synchronous pulleys 246. Buckets 248 are fixedly mounted on the outer periphery of the conveyor belt 243, and are equidistantly distributed around the outer periphery of the conveyor belt 243. A discharge rack 249 is mounted on the upper side of one side of the bucket conveyor frame 241, and a feed inlet 2410 is opened on the lower side of one side of the bucket conveyor frame 241. The discharge rack 249 and the feed inlet 2410 are located on the same upper and lower parts of the same side of the bucket conveyor frame 241. The end of 249 is connected to its feed section 21. The staff uses the conveying mechanism to continuously transport the azelaic acid crystal raw material to the feed section 21. After entering, the crystal will first enter the processing section 22. At this time, the first drive motor 233 starts and drives the driven crushing roller 232 to rotate. It works with the fixed crushing roller 234 to continuously crush the crystal. Regardless of whether the crushed crystal is qualified, it will be filtered by the screening frame 237 below. Qualified crystals will enter the mixing area in the tank 1, while larger unqualified crystals will roll down naturally with the help of the tilt angle of the screening frame 237 itself and the cooperation of the reset spring 236 and the movable shaft 238 connected at both ends. They will be guided to the bottom of the bucket conveyor frame 241 through the guide plate 239.At this time, the second drive motor 245 is started.

Since the upper conveyor shaft 242 is surrounded by a conveyor belt 243, the lower conveyor shaft 242 will also move accordingly. The conveyor belt 243 will work with the two conveyor shafts 242 to drive the surrounding hoppers 248 to circulate. When the hoppers 248 move to the bottom of the bucket conveyor frame 241, they will carry the defective crystals upwards until they pass the discharge rack 249, where they will be guided back to the feeding section 21 for secondary processing. This avoids the situation where defective crystals are left unattended and need to be removed by personnel for auxiliary processing, making it convenient and practical to use.

[0027] The mixing mechanism 3 includes a third drive motor 31, which is fixedly installed in the upper middle part of the tank 1. The output end of the third drive motor 31 is connected to a transmission rod 32, and stirring rods 33 are provided on both sides of a section of the transmission rod 32. Connecting rods 34 are fixed between the multiple stirring rods 33. The transmission rods 32 are equidistantly arranged along the vertical central axis of the transmission rods 32. After the crystals are crushed to a qualified state, they will be mixed with the required liquid in the tank 1. The stirring rods 33 arranged around the transmission rods 32, together with the multiple connecting rods 34 that are cross-fixed, can increase the mixing area of ​​the material and improve the shearing force on the material.

[0028] Working principle: Workers use a conveying mechanism to continuously feed azelaic acid crystal raw material to the feeding section 21. The crystals then enter the processing section 22. At this point, the first drive motor 233 starts, driving the driven crushing roller 232 to rotate. This roller, in conjunction with the fixed crushing roller 234, continuously crushes the crystals. Regardless of whether the crushed crystals are qualified, they are filtered through the screening screen 237 below. Qualified crystals enter the mixing zone inside the tank 1, while larger, unqualified crystals roll down naturally due to the tilt angle of the screening screen 237 and the cooperation of the return springs 236 and the movable shaft 238 connected to its two ends, and are guided by the guide plate 239 to the bottom of the bucket conveyor frame 241. Then, the second drive motor 245 is started. Driven by a set of synchronous belts 247 and two synchronous pulleys 246, the upper section of the conveyor frame... The conveyor shaft 242 will rotate. Since the upper conveyor shaft 242 is equipped with a conveyor belt 243, the lower conveyor shaft 242 will also move accordingly. The conveyor belt 243 will work with the two conveyor shafts 242 to drive the peripherally distributed hoppers 248 to circulate. When the hoppers 248 move to the bottom of the bucket conveyor frame 241, they will carry the unqualified crystals upwards until they pass the discharge rack 249 and are guided back to the feeding section 21 for secondary processing. This avoids the situation where unqualified crystals are left to stand and need to be taken out by personnel for auxiliary processing. It is convenient and practical to use. Secondly, after the crystals are crushed and qualified, they will be mixed with the required liquid in the tank 1. The stirring rods 33 distributed around the transmission rod 32, together with multiple cross-fixed connecting rods 34, can increase the mixing area of ​​the material and improve the shearing force on the material.
