There are multiple sets of clamping assemblies, each set of clamping assemblies is fixedly connected to the cleaning cover plate and is located at the lower end of the cleaning cover plate.

[0018] In this embodiment, the cleaning cover is placed at the upper end of the reactor and clamped by multiple sets of clamping components at the lower end of the cleaning cover to close the opening of the reactor. The first flange 103 and the second flange 104 are connected by bolts, thereby connecting the cleaning shaft 102 and the brush shaft 105. The driving motor 101 drives the cleaning shaft 102. When the cleaning shaft 102 rotates, the brush shaft 105 rotates with the cleaning shaft 102 while the first flange 103 and the second flange 104 are connected. One end of the multiple sets of cleaning brushes 106 contacts the reactor wall. During the rotation of the brush shaft 105, the multiple sets of cleaning brushes 106 continuously rotate to clean the inner side of the reactor wall.

[0019] Furthermore, the cleaning cover includes a plate body 107, an inlet pipe 108, and nozzles 109. There are multiple sets of inlet pipes 108, each set of which is fixedly connected to the plate body 107 and passes through the plate body 107. There are multiple sets of nozzles 109, each set of which is connected to the corresponding inlet pipe 108 and is located at one end of the corresponding inlet pipe 108.

[0020] In this embodiment, the plate 107 seals the opening of the reactor, and the liquid inlet pipe 108 is connected to an external liquid supply device. The cleaning liquid is pumped into the reactor through the liquid inlet pipe 108 and the nozzle 109. The spraying of the nozzle 109 can make the cleaning liquid evenly contact every part of the inner wall of the reactor, thereby improving the cleaning efficiency and the cleaning effect.

[0021] Furthermore, the cleaning cover plate also includes a directional sleeve 110 and a directional ring 111. The directional sleeve 110 is fixedly connected to the plate body 107 and is located at the lower end of the plate body 107. The directional ring 111 is fixedly connected to the cleaning shaft 102 and is sleeved on the outer wall of the cleaning shaft 102. The directional ring 111 and the directional sleeve 110 are mutually adapted.

[0022] In this embodiment, the directional ring 111 is embedded inside the directional sleeve 110, and the directional ring 111 is sleeved on the outer wall of the cleaning shaft 102. When the cleaning shaft 102 rotates, it is limited by the directional sleeve 110 and the directional ring 111 to prevent the cleaning shaft 102 from shaking or deflecting.

[0023] Furthermore, each clamping assembly includes a fixed plate 112, a threaded rod 113, a clamping arc plate 114, a rotating plate 115, and a handle 116. The fixed plate 112 is fixedly connected to the plate body 107 and is located at the lower end of the plate body 107. The threaded rod 113 is threadedly connected to the fixed plate 112 and passes through the fixed plate 112.

The rotating plate 115 is fixedly connected to the threaded rod 113 and is located at the end of the threaded rod 113 away from the clamping arc plate 114. The handle 116 is rotatably connected to the rotating plate 115 and is located on one side of the rotating plate 115.

[0024] In this embodiment, the threaded rod 113 is installed and fixed by the fixing plate 112. The clamping arc plate 114 and the rotating plate 115 are respectively installed at both ends of the threaded rod 113. The rotating plate 115 is driven to rotate by holding the handle 116, thereby driving the threaded rod 113 to rotate. The threaded rod 113 and the fixing plate 112 rotate threadedly to push the clamping arc plate 114 to move. Finally, the clamping arc plate 114 contacts the reaction vessel. Multiple clamps are used to fix the plate body 107.

[0025] Furthermore, each set of clamping components also includes guide rods 117, and there are two sets of guide rods 117. The two sets of guide rods 117 pass through the fixing plate 112 and are fixedly connected to the clamping arc plate 114.

[0026] In this embodiment, the two sets of guide rods 117 limit the horizontal drive of the clamping arc plate 114 to prevent the clamping arc plate 114 from flipping during movement, so that its arc surface cannot be tightly attached to the outer surface of the reactor, thus affecting the fixation of the plate 107.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
