It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model. Example

[0027] See also Figure 1-Figure 3A tailings filter press dry discharge device for non-ferrous metal beneficiation includes a support base 1, a liquid collecting box 2 and a pressure box 3. The liquid collecting box 2 is installed on the top of the support base 1, and the pressure box 3 is installed on the top of the liquid collecting box 2. A filter barrel 5 is installed in the pressure box 3, and the filter barrel 5 performs solid-liquid separation on the tailings slurry. A support frame 4 is fixedly connected to the top of the support base 1 by welding, and a mounting plate 6 is fixedly connected to the middle of the support frame 4. A cylinder 7 is installed in the middle of the mounting plate 6. A protective shell 30 is provided on the outside of the cylinder 7. The protective shell 30 protects the cylinder 7 to prevent the cylinder 7 from being damaged. In case of damage by external force, the movable rod of the cylinder 7 is provided with a pressing plate 8, and the operation of the cylinder 7 can drive the pressing plate 8 to move up and down in the vertical direction. Four limit frames 9 are fixedly connected to the top surface of the pressing box 3, and the four limit frames 9 are arranged diagonally. A fastening frame 10 for fixing the filter barrel 5 is slidably provided on the limit frame 9, and the fastening frame 10 is arc-shaped and matches the curvature of the surface of the filter barrel 5, so as to facilitate better clamping of the fastening frame 10, and a first elastic member 11 is sleeved on the limit frame 9, and the two ends of the first elastic member 11 are respectively connected to the limit frame 9 and the fastening frame 10.

[0028] When in use, the filter barrel 5 is fixed inside the press box 3 by four fastening frames 10, and then the tailings slurry is poured into the press box 3. After the solid-liquid separation in the filter barrel 5, part of the water flows downward into the collecting tank 2. Then the cylinder 7 is started, and the cylinder 7 drives the press plate 8 to move vertically downward into the filter barrel 5. The water in the solid matter is further squeezed out by pressure to form a mud cake with a low water content, thereby completing the tailings filtration operation. When the filter barrel 5 needs to be cleaned or replaced, the four fastening frames 10 can be pulled apart to loosen the filter barrel 5 and take it out. Example

The slag and mud particles quickly coagulate and settle from the water so that the tailings slurry can be separated. A push rod 22 is provided on the nozzle 21, and the push rod 22 is in contact with the pressure plate 8. When the pressure plate 8 moves downward, the pressure plate 8 can squeeze the push rod 22 to shrink the sleeve 20 and move the nozzle 21 backward out of the filter barrel 5 to make room for the pressure plate 8 to move downward. A guide frame 23 is fixedly connected to the push rod 22, and the guide frame 23 slide groove passes through the upper end of the fixed rod 1801 to guide the push rod 22.
