DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a filter press lower hopper. Figure 1-3A filter press lower hopper includes a discharge hopper 1. The outer walls on both sides of the outer wall of the discharge hopper 1 are fixedly connected with a first bracket 3. The bottom outer wall of the discharge hopper 1 is fixedly connected with an outlet box 6. The bottom outer wall of the outlet box 6 is provided with a discharge trough 13. The discharge of the filter press mud cake is convenient through the discharge trough 13. The outer walls on both sides of the outlet box 6 are rotatably connected with two closing plates 7. By driving the two closing plates 7 to rotate, the two closing plates 7 can control the discharge switch of the discharge trough 13, which is convenient for the staff to replace the collection frame. The outer walls of the two closing plates 7 are A second bracket 8 is fixedly connected, the outer wall of the first bracket 3 is rotatably connected to the first connecting block 4, the outer wall of the second bracket 8 is rotatably connected to the second connecting block 9, a hydraulic rod 5 is arranged between the second connecting block 9 and the first connecting block 4, and the hydraulic rod 5 is fixedly connected to the first connecting block 4 and the second connecting block 9, and the hydraulic rod 5 on both sides is synchronously started, so that the hydraulic rod 5 on both sides drives the closing plate 7 through the second bracket 8, so that the inner wall of the outlet box 6 is rotatably connected to the driving shaft 11, and the outer wall of the driving shaft 11 is fixedly connected to a plurality of stirring rods 12.

[0020] The top outer wall of the discharge hopper 1 is fixedly connected with a mounting frame 2, and the mounting frame 2 facilitates the installation of the discharge hopper 1.

[0021] The stirring rods 12 are L-shaped and are distributed in a linear array on the driving shaft 11, so as to better stir the mud cake and facilitate the dredging of the mud cake.

[0022] The outer wall of the outlet box 6 facing away from the driving shaft 11 is fixedly connected with a servo motor 10, and the output shaft of the servo motor 10 is fixedly connected to the driving shaft 11. The servo motor 10 is started by an external power supply to drive the driving shaft 11.

[0023] The outer walls of both sides of the discharge hopper 1 are fixedly connected with bin wall vibrators 14. By starting the bin wall vibrators 14 on both sides, the outer wall of the discharge hopper 1 is vibrated, thereby facilitating improving the discharge efficiency of the mud cake.

[0024] The implementation principle of a lower hopper of a filter press in an embodiment of the present application is as follows: the lower hopper is installed by placing the mounting frame 2 on the discharge hopper 1 in the mounting groove, so that when the mud cake of the filter press falls into the discharge hopper 1, the servo motor 10 is started by an external power supply, so that the servo motor 10 controls the driving shaft 11 to rotate, and then drives the multiple stirring rods 12 to rotate through the driving shaft 11, so that the multiple stirring rods 12 are rotated to slowly stir the mud cake, thereby preventing the mud cake from being blocked in the discharge trough 13. At the same time, when the collection frame does not need to be replaced and the mud cake is still falling, the hydraulic rods 5 on both sides can be started synchronously, so that the output shafts of the hydraulic rods 5 on both sides drive the second bracket 8 to rotate, so that the second bracket 8 drives the closing plate 7 to close the discharge trough 13, and then the mud cake is stored in the outlet box 6, which is convenient for replacing the collection frame.
