At this time, the locking block 282 is released and the second spring 283 drives the locking block 282 to return to its original position. The locking block 282 is sleeved on the short end of the L-shaped frame 27, and the L-shaped frame 27 is locked and cannot be rotated. When unlocking is required, the locking block 282 is pushed so that the locking block 282 compresses the second spring 283 and no longer sleeves on the short end of the L-shaped frame 27.

Specifically, the two docking blocks 14 of one filter device are respectively inserted into the two docking mechanisms 15 of the other filter device, so that the two filter devices can be docked and installed together; this makes it convenient to first install the pressure vessel 3 on the bracket 13 from the side through the mounting assembly 2, and then splice together several filter devices described in this application, without causing obstruction during the installation process, and several filter devices described in this application can be selected and spliced ​​according to actual production needs.

During insertion, the two clamping blocks 152 will be squeezed along the inclined surface 1521, and the two clamping blocks 152 will gradually retract into the two mounting cavities 1511 respectively. The two third springs 154 are compressed until the end of the docking block 14 is completely inserted into the insertion cavity 1512. At this time, the end of the docking block 14 passes over the two clamping blocks 152 and no longer blocks the two clamping blocks 152. At this time, the two third springs 154 push the two clamping blocks 152 to extend out of the two mounting cavities 1511, locking the end of the docking block 14 to complete the docking.

[0040] Furthermore, the docking mechanism 15 further includes two bottom connecting blocks 155 , an elastic rod 156 , a top connecting block 157 and two connecting rods 158 ; The two bottom connecting blocks 155 are respectively fixed on one side of the two guide rods 153; the elastic rod 156 is fixed on the top of the mounting seat 151; the top connecting block 157 is fixed on the top of the elastic rod 156; the top ends of the two connecting rods 158 are respectively rotatably connected to the top connecting blocks 157, and the bottom ends of the two connecting rods 158 are respectively rotatably connected to the two bottom connecting blocks 155.

The top connecting block 157 drives the two bottom connecting blocks 155 away from each other through the two connecting rods 158, thereby driving the two guide rods 153 away from each other, and the two guide rods 153 drive the two blocking blocks 152 to gradually retract into the two mounting cavities 1511, no longer blocking the end of the docking block 14. At this time, the docking block 14 of one of the filter devices can be taken out from the insertion cavity 1512 of the mounting seat 151 of the other filter device; release the top connecting block 157, and the elastic rod 156 drives the top connecting block 157 to move up and reset, and the two bottom connecting blocks 155 also move and reset.
