Description

Technical Field

[0001] The utility model belongs to the technical field of dryers, and particularly relates to a combined circulating spray dryer. Background Art

[0002] A spray dryer is a device that can simultaneously complete drying and granulation. According to process requirements, the pressure, flow rate of the feed liquid pump, and the size of the spray holes can be adjusted to obtain spherical particles with a required size ratio. The spray dryer is a type of continuous atmospheric pressure dryer. A special device is used to spray the liquid material into a mist, which is then dried by contacting with hot air. The existing spray dryer is a device that can simultaneously complete drying and granulation. According to process requirements, the pressure, flow rate of the feed liquid pump, and the size of the spray holes can be adjusted to obtain spherical particles with a required size ratio. The spray dryer is a type of continuous atmospheric pressure dryer. A special device is used to spray the liquid material into a mist, which is then dried by contacting with hot air.

[0003] Therefore, a dust-free closed-circuit spray dryer with the publication number of "CN218686378U" includes an upper shell, a lower shell, a motor, a rotating shaft, a stirring rod, a sealing groove, a sealing block, and a fixing mechanism. The bottom of the upper shell is movably provided with the lower shell, the center of the top of the upper shell is fixedly connected with a motor, and the output shaft of the motor is fixedly connected with a rotating shaft. The bottom of the rotating shaft sequentially penetrates through the upper shell and the lower shell and extends into the interior of the lower shell. When maintenance of the stirring rod is required, only need to rotate the screw sleeve counterclockwise, so that the screw sleeve disengages from the stud, then pull the limit plate to the side away from the upper shell, so that the limit plate disengages from the stud, then pull the upper shell upward, thus driving the motor, the rotating shaft and the stirring rod to move upward, so that the sealing block disengages from the sealing groove, and then the stirring rod can be taken out from the lower shell. Through the above steps, it is convenient for users to maintain the stirring rod.

[0004] However, for the above-mentioned dust-free closed-circuit spray dryer, although when maintaining the stirring rod, only need to rotate the screw sleeve counterclockwise, so that the screw sleeve disengages from the stud, then pull the limit plate to the side away from the upper shell, so that the limit plate disengages from the stud, then pull the upper shell upward, thus driving the motor, the rotating shaft and the stirring rod to move upward, so that the sealing block disengages from the sealing groove, and then the stirring rod can be taken out from the lower shell. There are still the following obvious defects during use: Although the stirring rod in the above dryer can be disassembled for maintenance, however, due to the large volume of the dryer, and the length of the stirring rod is long, the upper shell needs to be lifted to a certain height before the stirring rod can be disassembled for maintenance. Therefore, it is impossible for manual labor to lift the upper shell to a high position to disengage the stirring rod from the lower shell for disassembly and maintenance. Thus, a hoisting device is required to lift it in order to disassemble the stirring rod for inspection and maintenance. Furthermore, the disassembly and assembly in this way are relatively troublesome and also require a lot of time. Summary of the Utility Model

[0015] Through the combined jacking cylinders on the drying tank, the combined jacking cylinders are fixed in the connecting end lock sleeves arranged on both sides of the combined lifting tank cover by means of plugging and locking. The dismountable and installable stirring shaft of the drying tank is fixedly connected to the drying motor by means of the combination of a dismountable and installable flange A and a dismountable and installable flange B. During disassembly and assembly, the combined jacking cylinders use the connecting end lock sleeves to push the combined lifting tank cover to move away from the drying tank to one side, causing the dismountable and installable stirring shaft to move outwards and be exposed outside, so that the dismountable and installable stirring shaft can be disassembled, assembled, and replaced. Moreover, it is beneficial to clean the cleaning scraper. At the same time, the combined lifting end cover can be removed for overhaul by using the connecting end lock sleeve. After cleaning and assembly, the combined jacking cylinders are used to seal and combine the combined lifting tank cover and the drying tank, so that the hoisting equipment can be used infinitely for hoisting, combination, disassembly, and assembly, and the speed of disassembly and assembly is improved. The disassembly and assembly of the dryer are made simpler and more convenient. Description of the Drawings

On both sides of the outer port of the drying tank 1, there are combined lifting cylinders 4 for disassembling and assembling the drying tank 1, so that the combined lifting tank cover 5 can be combined and lifted, and there is no need for limit fixing by screwing after combination;

[0023] The combined lifting tank cover 5 is hermetically combined at the end of the drying tank 1. By adjusting the angle of the drying tank 1, the combined lifting tank cover 5 can be adjusted to a suitable position for disassembly and assembly. And at the center position of the inner top end of the combined lifting tank cover 5, there is a drying disassembly and assembly stirring shaft 6 for stirring and drying the raw materials and cleaning the residues, which drives the cleaning scraper 12 to rotate to scrape and clean the inner wall of the drying tank 1. On both sides of the combined lifting tank cover 5, there are connecting end lock sleeves 7 which are combined and plugged with the combined lifting cylinders 4, so that the combined lifting tank cover 5 can be separated and combined with the combined lifting cylinders 4, which is convenient for driving and combining the installation of the drying tank 1 and the combined lifting tank cover 5, and there is no need to spend a lot of time for combined installation and fixing by hoisting.
