Description

Technical Field

[0001] This utility model relates to the technical field of atomizer types, specifically a quick-assembly and disassembly structure for a spray dryer atomizer. Background Technology

[0002] The core working principle of a spray dryer is to atomize liquid materials into tiny droplets, which are then rapidly brought into contact with a hot airflow, causing the moisture to evaporate instantly, ultimately yielding dried powder or granules. Its main function is to achieve rapid dehydration and shaping of liquid materials, and it is widely used in the food, pharmaceutical, and chemical industries. Liquid materials (such as solutions, suspensions, and slurries) are dispersed into tiny droplets with diameters ranging from a few micrometers to tens of micrometers by an atomizer (centrifugal, pressure, or airflow type). The surface area of ​​the droplets is significantly increased, laying the foundation for subsequent rapid drying.

[0003] For example, patent CN221108707U discloses an atomizer nozzle that is easy to assemble and disassemble quickly, relating to the field of atomizing nozzles. This utility model includes a nozzle head and a connecting tube. A connecting assembly for easy assembly and disassembly of the nozzle head is installed between the nozzle head and the connecting tube. The connecting assembly includes a connecting plate fixedly installed on both sides of the connecting tube and a second snap-fit ​​plate fixedly installed inside the nozzle head for engaging with the connecting tube. When the nozzle head needs to be disassembled, the first snap-fit ​​plate is pulled outwards. When the first snap-fit ​​plate disengages from the snap-fit ​​groove, the elastic force of a second spring causes a limiting plate to move outwards, and the second snap-fit ​​plate pops outwards, completing the disassembly. When the nozzle head needs to be installed, the second snap-fit ​​plate moves inwards towards the connecting plate. When the snap-fit ​​groove moves to the position of the first snap-fit ​​plate, the first snap-fit ​​plate springs into the snap-fit ​​groove by the elastic force of a first spring, completing the engagement. This assembly enables quick assembly and disassembly of the nozzle head, facilitating cleaning and replacement of the nozzle head.

[0004] However, when the atomizer of this application, which is easy to disassemble and assemble quickly, is used in a spray dryer system, it is difficult to quickly disassemble and assemble the feeding and air inlet pipes, which is inconvenient for subsequent production and maintenance.

[0019] Please see Figure 1-4 A quick-assembly and disassembly structure for a spray dryer atomizer includes an atomizer base 1, a mounting plate 2 fixedly connected to the lower end of the atomizer base 1, a threaded mounting seat 3 fixedly mounted to the lower end of the mounting plate 2, a drying vessel 5 threadedly connected to the lower end of the mounting plate 2 via the threaded mounting seat 3, a detachable airflow atomizer body 4 mounted on the upper end of the atomizer base 1, an air inlet 22 opened at the upper end of the airflow atomizer body 4, a filter element 23 installed inside the air inlet 22, and a fixed connection at the lower end of the airflow atomizer body 4. An air outlet pipe 18 is connected to the upper end of the atomizer base 1 and is fixedly connected to the lower part of the air outlet pipe 18. An elastic connecting ring 21 is tied to the lower end surface of the air outlet pipe 18. An air inlet connector 20 is installed inside the lower end of the air outlet pipe 18 through the elastic connecting ring 21. A feed pipe 13 is fixedly connected to the upper end of the atomizer base 1. An infusion pipe 10 is detachably connected to the other end of the feed pipe 13 away from the atomizer base 1. An upper hot air pipe 11 is fixedly connected inside the mounting plate 2 and located at the side end of the atomizer base 1.

[0020] This device features a three-section design for the atomizer's connector. The atomizer base 1 is the uppermost section, used to install the detachable airflow atomizer body 4, the air outlet pipe 18, and the liquid delivery pipe 10. The liquid delivery pipe 10 is used to install a liquid material conveying device, delivering the material requiring drying to the feed pipe 13. Both the feed pipe 13 and the liquid delivery pipe 10 have external threads. The top of the liquid delivery pipe 10 can be installed inside the feed pipe 13, and the two are connected via a threaded connector 15 installed on the surface of the feed pipe 13. The material end can be quickly disassembled and reassembled for easy subsequent inspection of feeding blockages. An air inlet connector 20 installed at the upper end of the atomizer base 1 is used to connect to an air outlet pipe 18. The air outlet pipe 18 can be fitted onto the surface of the air inlet connector 20 and bound together by an elastic connecting ring 21. A bolt is installed at the end of the elastic connecting ring 21, which can be tightened by rotating the bolt nut to fix the air outlet pipe 18 to the surface of the air inlet connector 20. An air inlet 22 at the upper end of the airflow atomizer body 4 is used to draw in external air. The air is filtered by the filter element 23. Finally, the pressurized airflow output from the airflow atomizer body 4 is input into the air inlet connector 20 and the interior of the mounting plate 2 through the air outlet pipe 18. An atomizing nozzle 19 is installed inside the mounting plate 2. The airflow and the liquid material entering through the feed pipe 13 can be carried out by the airflow and finally formed into an atomized airflow by the atomizing nozzle 19. The surface of the atomizer base 1 has threaded grooves, which can be connected to the support plate 16 by screws, so as to quickly assemble and disassemble the airflow atomizer body 4. The filter element 23 at the top of the airflow atomizer body 4 can be quickly removed and replaced to keep the pressurized airflow clean.

[0021] Mounting plate 2 is the middle part of the atomizer's connecting seat, and threaded mounting plate 3 is the lower part of the connecting seat for mounting to the surface of the drying vessel 5. The liquid flow entering through the feed pipe 13 and the pressurized airflow added through the air outlet pipe 18 can converge into it. When disassembling and assembling the atomizer's connecting seat as a whole, the threaded mounting plate 3 can be rotated by holding the handle 17 on the side of the atomizer base 1, thereby disassembling and assembling it from the drying vessel 5.

When the filter element 23 needs to be replaced, the air inlet cover 12 can be removed. During installation, it can be installed at the port of the air inlet 22 with screws.

[0023] Please see Figure 1-2 A support plate 16 is fixedly connected to the bottom side of the airflow atomizer body 4, and a mounting plate 2 is installed on the lower end of the support plate 16 by screws. When disassembling and maintaining the airflow atomizer body 4, the connection between the air outlet pipe 18 and the air inlet connector 20 can be removed first, and then the connection between the support plate 16 and the atomizer base 1 can be removed.

[0024] Please see Figure 1-2 A second valve 14 is installed on the surface of the feed pipe 13, and a threaded connector 15 is threadedly connected to the surface of the feed pipe 13. An infusion pipe 10 is installed at the top of the feed pipe 13 through the threaded connector 15. The second valve 14 is used to control the addition of liquid materials, and the design of the threaded connector 15 allows for quick disassembly and assembly of the infusion pipe 10, facilitating the detection of material blockage during equipment maintenance.

[0025] Please see Figure 1-2 Multiple handles 17 are fixedly connected to the side of the atomizer base 1. The handles 17 are convenient for staff to hold, and pushing the handles 17 can drive the mounting plate 2 to rotate.
