[0036] Working principle:

[0037] The adhesive enters the installation cylinder one 21 of the coarse filter 2 from the feed port, and flows from top to bottom under the action of gravity. In this process, the coarse filter screen 22 plays an interception role, and blocks the impurity particles with a larger particle size in the adhesive on the screen surface, so that the preliminarily filtered adhesive flows downward through the coarse filter screen 22, and the coarse filtering process is completed.

[0038] When the intercepted impurities of the coarse filter screen 22 reach a certain degree and need to be cleaned, the motor two 45 in the lifting mechanism 4 is started. The motor shaft of the motor two 45 drives the screw rod 41 to rotate, since the threaded sleeve 42 is matched with the screw rod 41 through thread, the rotation of the screw rod 41 makes the threaded sleeve 42 produce upward or downward linear motion. The threaded sleeve 42 is connected with the lifting block 43, the lifting block 43 is provided with a guide hole 46, the guide shaft 44 is inserted into the guide hole 46 to provide guidance for the movement of the lifting block 43, and ensure that the lifting block 43 stably rises along the vertical direction until the lifting block 43 drives the filter screen cleaning mechanism 5 to reach the position of the coarse filter screen 22.

[0039] The motor three 52 is started, the motor shaft of the motor three 52 drives the bevel gear one 53 to rotate. The bevel gear one 53 is engaged with the bevel gear two 54, so as to drive the bevel gear two 54 to rotate. The bevel gear two 54 is connected with the rotating shaft 56 in the mounting sleeve 55, the rotating shaft 56 rotates with the rotation of the bevel gear two 54, and the cleaning brush 57 connected with the other end of the rotating shaft 56 also rotates. The rotating cleaning brush 57 fully sweeps the coarse filter screen 22, and the impurities attached to the coarse filter screen 22 are brushed off, so that the coarse filter screen 22 restores good filtering performance.

[0040] The coagulant after coarse filtration enters the installation cylinder two 31 of the rotating filter assembly 3. The motor one 34 is started, and the motor shaft of the motor one 34 drives the belt pulley two 35 to rotate. The belt pulley two 35 drives the belt pulley one 33 on the outer wall of the installation cylinder two 31 to rotate through the belt 36, so that the installation cylinder two 31 rotates around the axis in the installation seat 32. The fine filter screen 37 arranged concentrically in the installation cylinder two 31 rotates with the installation cylinder two 31, and the coagulant passes through the fine filter screen 37 under the joint action of centrifugal force and gravity, and the fine particles in the coagulant are intercepted on the fine filter screen 37, so that fine filtration of the coagulant is realized. The coagulant after fine filtration flows out from the discharge port of the device and can enter the subsequent storage or processing link.
