[0025] Two shock absorbers 631 are arranged between one end of the inner wall of the installation frame 63 and the other end of the fixing block 64 , and the surface of the fixing block 64 is slidably matched with the inner wall of the installation frame 63 .

[0026] Connecting plates 611 are fixedly disposed on both sides of the connecting seat 61 , and connecting blocks 612 are fixedly disposed on the top ends of the two connecting plates 611 .

[0027] The middle part of the connecting block 612 is threadedly connected with a screw rod 613, and a hand-tightening block is fixedly provided on the top of the screw rod 613. The height of the screw rod 613 is adjusted by rotating the hand-tightening block. The bottom end of the screw rod 613 conflicts with the top end of the block 62, which can prevent the block 62 from falling off accidentally.

[0028] The circulation component 8 includes two fixed rods 80, which are respectively fixed on both sides of the bottom of the inner wall of the reaction tube 1, and a stator head 81 is fixed between the two fixed rods 80. A connecting groove 82 is provided at the top of the stator head 81, a liquid outlet hole 83 is provided on the surface of the stator head 81, and a liquid inlet hole 84 is provided at the bottom of the stator head 81 to facilitate the entry of liquid.

During operation, the bottom end of the screw rod 613 is in contact with the top end of the block 62 to limit the movement of the block 62, thereby avoiding the accidental falling off of the block 62. At the same time, the block 62 and the connecting seat 61 are easily disassembled structures, which can facilitate daily maintenance of the scraper 65.
