2. A polyacrylamide dosing device according to claim 1, characterized in that: The top of the hopper (11) is hinged with a cover plate (2), which is used to close the hopper (11).

3. A polyacrylamide dosing device according to claim 2, wherein: The inner bottom wall of the hopper (11) is configured as two symmetrical and inclined surfaces (111), the bottom of which extends to the feed inlet (121).

4. A polyacrylamide dosing apparatus as claimed in claim 3, wherein: A cylinder (21) is fixedly installed on the cover plate (2). The output end of the cylinder (21) extends into the hopper (11) and is fixedly installed on a bracket (22). Cleaning plates (23) are symmetrically arranged on both sides of the bracket (22). The cleaning plates (23) correspond one-to-one with the inclined surface (111). The two cleaning plates (23) slide and connect with the bracket (22) in a direction that is close to or far away from each other. A sliding mechanism (3) for driving the cleaning plates (23) to slide is provided on the bracket (22). Brushes (231) are provided on the cleaning plates (23). The brushes (231) can contact the inclined surface (111).

5. A polyacrylamide dosing apparatus as claimed in claim 4, wherein: The sliding mechanism (3) includes a second motor (31), an intermediate gear (32), and a rack (33). The second motor (31) is fixedly connected to the bracket (22). The intermediate gear (32) is coaxially fixed with the drive shaft of the second motor (31). The rack (33) corresponds to and is fixedly connected to the cleaning plate (23). One rack (33) meshes with one side of the intermediate gear (32), and the other rack (33) meshes with the other side of the intermediate gear (32).

6. The polyacrylamide quantitative safety feeding device according to claim 5, characterized in that: An isolation cover (221) is fixedly installed on the bracket (22), and the second motor (31) is located inside the isolation cover (221).

7. A polyacrylamide dosing device according to claim 2, wherein: A downwardly extending support rod (411) is hinged and inclined on the side wall of the cover plate (2). A slide rail (4) is fixedly installed on the side wall of the hopper (11). A slider (41) is slidably installed inside the slide rail (4). The end of the support rod (411) away from the cover plate (2) is hinged to the slider (41). A locking member (412) for fixing the slider (41) and the slide rail (4) is also provided on the slider (41).

8. A polyacrylamide dosing device according to claim 7, wherein: The locking component (412) includes a handle (4121), which is rotatably connected to the slider (41). A protrusion (4122) is integrally formed on the handle (4121), which can contact the slide rail (4) and press the slide rail (4).
