A groove 6 is opened on the top of the frame body 1, and a through groove 11 is opened at the bottom of the inner cavity of the groove 6. A filter plate 8 is placed on the bottom of the inner cavity of the groove 6. A plurality of evenly distributed leakage holes 9 are opened on the filter plate 8, and the plurality of leakage holes 9 correspond to the through grooves 11. The filter membrane body 7 is attached to the top of the filter plate 8. A pressing plate 13 is attached to the top of the filter membrane body 7 near the left and right sides. The inner walls of the left and right sides of the groove 6 are provided with mounting grooves 18. The inner walls of the mounting grooves 18 are slidably connected with electric push rods 17, and the opposite ends of the two electric push rods 17 are connected to the inner wall of the mounting grooves 18 by bolts. A slide groove matching the slider is provided on the inner wall of the mounting groove 18 on the side wall of the pressure plate 13, and the slider is connected to the side away from the two electric push rods 17 by bolts, and the bottom of the electric push rod 17 is connected to the buffer spring 16 by bolts, and the bottom end of the buffer spring 16 is connected to the bottom of the inner cavity of the mounting groove 18, the top of the electric push rod 17 is connected to the T-shaped rod 12 by bolts, and the T-shaped rod 12 is placed in the mounting groove 18, the bottom of the electric push rod 17 is connected to the limit rod 15 by bolts, and the inner cavity bottom of the mounting groove 18 is provided with a limit groove 14 matching the limit rod 15, and the buffer spring 16 is sleeved outside the limit rod 15, so that it can effectively fix and clamp the filter membrane body 7 and the filter plate 8, so that it is easy to deviate when in use, thereby improving its use efficiency;

[0027] The bottom of the inner cavity of the groove 6 is connected with a shell 3 near the left and right sides, the bottom of the shell 3 extends to the bottom of the bracket body 1, and the bottom of the inner cavity of the shell 3 is connected with an electric telescopic rod 10 by bolts, and the top of the inner cavity of the shell 3 is provided with a through hole matching the electric telescopic rod 10, and the top of the electric telescopic rod 10 is connected to the bottom of the filter plate 8 through the through hole, so that the filter membrane body 7 and the filter plate 8 can be easily moved out or moved in, so that the filter membrane can be easily attached to the filter plate, so that it can be convenient to take out and put the mold, thereby improving its working efficiency.
