[0022] In the embodiment of this example, the disassembly and assembly structure includes a mounting frame 41 fixedly mounted between the front and rear side walls of the inner cavity of the mounting frame 1, a support frame 42 is slidably mounted inside the mounting frame 41, and a limit bar is fixedly mounted on the front and back of the support frame 42. A limit groove is provided on the front and back of the screen box 3, and the inner wall of the limit groove is slidably connected to the outer surface of the limit bar to facilitate limiting the insertion of the screen box 3 into the interior of the support frame 42. One end of the screen box 3 passes through the interior of the support frame 42, and a connecting frame 43 is fixedly mounted on the outer surface of the support frame 42. Two fixing members 44 for fixing the screen box 3 are slidably mounted inside the connecting frame 43. The two fixing parts 44 each include a connecting plate and two locking plates. The two locking plates are fixedly installed on one side of the connecting plate. One end of the two locking plates passes through and extends to the interior of the screen box 3, so that the two fixing parts 44 can be used to lock the position of the screen box 3. The internal rotatable installation of the connecting frame 43 has a threaded rod 45 with one end passing through and extending to the outside thereof. The two fixing parts 44 are respectively threadedly installed on the outer surface of the threaded rod 45 and are symmetrically distributed on the left and right, so that rotating the threaded rod 45 can control the movement of the fixing part 44. The outer surface of the threaded rod 45 is fixedly connected with a ring handle 46 to facilitate the rotation of the threaded rod 45.

[0023] Among them, guide strips are fixedly installed on the front and rear side walls of the inner cavity of the connecting frame 43, and guide grooves are opened on the front sides of the two connecting plates. The outer surface of the guide strip is slidably connected to the inner wall of the guide groove, which is convenient for limiting the connecting plate to move left and right only on the outer surface of the guide strip.

[0024] By adopting the above technical solution, the annular handle 46 is rotated, so that the annular handle 46 drives the threaded rod 45 to rotate, and then the two fixing parts 44 threadedly connected on the outer surface of the threaded rod 45 move toward opposite sides until the locking plate in the fixing part 44 exits the interior of the screen box 3, so that the staff can pull the screen box 3 out from the inside of the support frame 42 and directly pour out the large-particle impurities screened in the screen box 3.

[0025] In this embodiment, the screening structure includes a telescopic cylinder 47 fixedly installed on one side of the mounting frame 41, and the telescopic end of the telescopic cylinder 47 is fixedly connected to one side of the support frame 42. Support components 48 are provided on the left and right sides of the support frame 42. The support component 48 includes two support plates. Rectangular grooves are provided on the left and right sides of the mounting frame 41. One end of the two support plates passes through the rectangular grooves respectively. The two support plates are fixedly installed on the left and right sides of the support frame 42 respectively, so as to facilitate the support of the screen box 3 and the support frame 42 to slide left and right. A dustproof component 49 for isolating phosphogypsum dust is provided on the mounting frame 1 to isolate the generated dust.

The front and back sides of the dustproof plate are provided with slide grooves, and the inner wall of the slide groove is slidably connected to the outer surface of the slide bar to facilitate the isolation of dust generated during the screening process.

[0027] By adopting the above technical solution, the telescopic cylinder 47 is started and the support frame 42 is driven to move. Under the action of the two support plates in the support assembly 48, the support frame 42 drives the screen box 3 to move back and forth left and right inside the installation frame 41, and the screen box 3 is used to screen out large particles of impurities in the phosphogypsum, and the generated phosphogypsum dust is isolated by the dustproof plate in the dustproof assembly 49.

[0028] The working principle of the above embodiment is:

[0029] When the reactor for pretreatment of phosphogypsum is in use, the telescopic cylinder 47 is started and the support frame 42 is driven to move. Under the action of the two support plates in the support assembly 48, the support frame 42 drives the screen box 3 to move back and forth left and right inside the installation frame 41, and uses the screen box 3 to screen out large particles of impurities in the phosphogypsum, and isolates the generated phosphogypsum dust through the dustproof plate in the dustproof assembly 49. After the screening is completed, the annular handle 46 is rotated so that the annular handle 46 drives the threaded rod 45 to rotate, thereby causing the two fixing parts 44 threadedly connected to the outer surface of the threaded rod 45 to move toward opposite sides until the locking plate in the fixing part 44 exits the interior of the screen box 3, so that the staff can pull the screen box 3 out of the support frame 42 and directly pour out the large particles of impurities screened in the screen box 3.
