Example one

Referring to fig. 2, the present application provides a rotary screen track sealing mechanism, which includes a shielding portion 2 disposed on a bottom wall 1 of a flow channel, in this embodiment, the shielding portion 2 is made of concrete, but of course, bolts may be used to bolt the shielding portion 2 on the bottom wall of the shielding portion 2. The top surface of the shielding part 2 is provided with a depressed area 21 for avoiding the movement of the screen frame 11, and the depressed area 21 is configured as follows:

when the rotary filter screen runs, the first end of at least one screen frame 11 is abutted against the inner wall of the recessed area 21; at most two first ends of the frame 11 abut against the inner wall of the recessed area 21.

Referring to fig. 2, specifically, the inner wall of the concave area 21 is a smooth curved surface, and the inner wall of the concave area 21 coincides with the path of the first end of the screen frame 11. The width of the inner wall of the recessed area 21 is set as: the width of the inner wall of the recessed area 21 is larger than the distance between the first ends of two adjacent net frames 11. When the rotary filter screen is operated, the first end of the screen frame 11 slides into the recessed area 21 and then is kept against the inner wall of the recessed area 21.

Referring to fig. 2, further, the top surface of the shielding portion 2 is provided with a guiding portion 22, the guiding portion 22 is an inclined surface formed at the edge of the top surface of the shielding portion 2, the top edge of the inclined surface is engaged with the edge of the recessed area 21, when the impurities move with the water flow and fall on the guiding portion 22, the guiding portion 22 can guide the impurities on the top surface of the shielding portion 2 to fall on the bottom wall 1 of the flow passage, so as to prevent the impurities on the top surface of the shielding portion 2 from being scraped into the recessed area 21 by the first end of the mesh frame 11.

Referring to fig. 2, further, the edge of the recessed area 21 is further processed with a first chamfer 211, when the first end of the screen frame 11 collides with the edge of the recessed area 21, the first end of the screen frame 11 contacts the first chamfer 211, but does not contact the edge of the recessed area 21, so as to prevent the edge of the recessed area 21 from scratching the first end of the screen frame 11.

In addition, the arrows in the drawings indicate the moving direction of the screen frame 11 located at the bottom end of the rotary screen when the rotary screen is operated.

The working principle is as follows:

the bottom wall 1 of the flow channel is provided with a shielding part 2 with a recessed area 21, when the rotary filter screen runs, the first end of the screen frame 11 slides into the recessed area 21, and when the first end of the screen frame 11 is positioned in the recessed area 21, the first end of the screen frame 11 is kept against the inner wall of the recessed area 21.
