[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Embodiment: Refer to Figures 1-5 , a spray dryer convenient for maintenance, including a top cover 1, a positioning plate 2 is installed on the top cover 1, support blocks 3 are arranged on the outer side of the positioning plate 2, there are two support blocks 3, and the two support blocks 3 are symmetrically installed on the outer surfaces on both sides of the positioning plate 2. A high-speed centrifugal nozzle is arranged at the center position of the positioning plate 2. A movable stop block 7 is installed at one end of the support block 3. One side of the movable stop block 7 is connected with a limiting plate 5. A positioning insertion rod 6 is installed at one end of the limiting plate 5. A plug-in part 8 is also connected to the support block 3. The plug-in part 8 includes an arc-shaped block 11, a positioning rod 12 and an insertion plate. The positioning rod 12 and the insertion plate are both installed on the arc-shaped block 11. An insert block 10 is also connected in the insertion plate. Two bases 4 are arranged on the top cover 1. One end of the limiting plate 5 is rotatably connected in the base 4 to act on the horizontal rotation of the limiting plate 5. The limiting plate 5 includes two support rods and two frame plates. The two frame plates are fixedly installed between the two support rods. The bottom end of one of the support rods is connected in the base 4, and a positioning insertion rod 6 is installed in the other support rod to act on the positioning after the frame plate rotates.

[0023] In this embodiment, two arc grooves 9 are formed on the top surface of the top cover 1. Inner holes are formed on the bottom surface at one end of the arc grooves 9. The positioning insertion rod 6 is connected to the support rod by a spring and is used for positioning after the limiting plate 5 and the support block 3 are connected. The top end of the positioning insertion rod 6 extends above the top surface of the support rod. After being pulled upward, the limiting plate 5 can rotate at an angle. The bottom end of the positioning insertion rod 6 is connected to the inner hole. Sunk grooves 15 are formed on the top and bottom surfaces at the outer end of the support block 3. The positions of the two support plates correspond to those of the sunk grooves 15. The support plates are connected to the sunk grooves 15 to position the positioning plate 2 and prevent it from moving up and down. A cavity is formed on one side of the sunk groove 15 to facilitate the rotation of the movable stop block 7 and prevent it from blocking the rotating limiting plate 5. Two fixed shafts 16 are installed between the inner walls of the cavity. Movable stop blocks 7 are movably connected to the outer sides of the fixed shafts 16. Positioning holes 17 are formed corresponding to each other on the support block 3 and the movable stop blocks 7. A positioning rod 12 is connected to the positioning holes 17 to limit the movable stop blocks 7. A plate groove is horizontally formed in the support block 3 and is located between the positioning holes 17. The bottom surfaces of the movable stop blocks 7 are all horizontal. By contacting between the bottom surfaces of the movable stop blocks 7, secondary positioning of the movable stop blocks 7 is achieved. An insertion plate is connected to the plate groove. A slot 14 is vertically formed on the top surface of the support block 3. An insertion block 10 is inserted into the slot 14. Sockets are also formed on the insertion plate. The insertion block 10 is inserted into the sockets to fix the connector 8. Semi-circular rotating pressing pieces 13 are symmetrically installed on both sides at the top end of the slot 14. The rotating pressing pieces 13 are connected to the top surface of the insertion block 10 to position the insertion block 10, thus completing the positioning of the entire structure.

[0024] Working principle: After the spray drying and maintenance are completed, the positioning plate 2 is installed at the designated position. Then, the limiting plate 5 is rotated. The support plates on the limiting plate 5 will move into the sunk grooves 15. Then, the two movable stop blocks 7 are rotated to keep them in a vertical state. Then, the connector 8 is inserted. The positioning rod 12 will be inserted into the positioning holes 17 in the movable stop blocks 7 and the support block 3. The insertion plate will be inserted into the plate groove. After the connector 8 is completely inserted, the insertion block 10 is inserted from the slot 14 to position the connector 8. After the insertion block 10 is completely placed, the rotating pressing piece 13 is rotated. The rotating pressing piece 13 will position the insertion block 10. When maintenance is required, reverse the above operations.
