[0009] The present invention is further described below with reference to the accompanying drawings and embodiments, but is not intended to be limiting of the present invention.

[0010] See also Figure 1 As shown, the utility model provides a filter packing clamping device, the structure of which includes: a tank cover (1) is formed by welding an upper head and a container flange, a screw box (13) is welded and fixed to a central opening on the tank cover (1), and an operation hole (9) is welded and fixed to a convenient operation position opening on the tank cover (1); a tank body (2) is formed by welding a cylinder and a container flange, and the tank cover (1) and the tank body (2) are connected by flanges. A screw (8) passes through a threaded hole in the center of a clamping member (3) and is connected by threads; at the top of the clamping member (3), a limit block 1 (7) and a locking member 1 (4) are connected to the screw (8) by threads, the limit block 1 (7) plays a limit adjustment role, and the locking member 1 (4) plays a locking role; at the bottom of the clamping member (3), a limit block 2 (6) and a locking member 2 (5) are connected to the screw (8) by threads, the limit block 2 (6) plays a limit adjustment role, and the locking member 2 (5) plays a locking role. The lead screw (8) passes through the threaded hole in the center of the lead screw box (13) and is threadedly connected. Inside the lead screw box (13), the lead screw (8) is threadedly connected to the adjusting member 2 (11) and the locking member 3 (12). The adjusting member 2 (11) plays a limit adjustment role, and the locking member 3 (12) plays a locking role. At the bottom of the lead screw box (13), the lead screw (8) and the adjusting member 1 (10) are threadedly connected, and the adjusting member (10) plays a limit adjustment role.
