Description

Technical Field

[0001] This utility model belongs to the field of magnesite flotation tailings technology, and in particular relates to a filter press for magnesite flotation tailings. Background Technology

[0002] Tailings dry stacking is a new tailings treatment process that has been promoted in China in recent years. Its core is to process the tailings slurry generated from mineral processing through multi-stage thickening and dewatering equipment, and transform it into dry slag with low water content that is easy to solidify and store, making it convenient for transportation and designated storage. In this process, the filter press, as a key solid-liquid separation device, applies pressure through special filter plates to make the liquid seep out, while the solid forms a filter cake that remains in the filter chamber.

[0003] However, during the unloading process of existing filter presses, some filter cake adheres to the surface of the filter plates and is difficult to remove, increasing the cost of manual cleaning. Therefore, how to optimize the structure or working method of the filter press to achieve efficient removal of filter cake has become an urgent technical problem to be solved in the tailings dry discharge process. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a filter press for magnesite flotation tailings, which solves the technical problem that some filter cake will adhere to the surface of the filter plate during unloading and is difficult to remove.

[0005] To achieve the above objectives, the main technical solutions adopted by this utility model include: A filter press for magnesite flotation tailings includes a first vertical plate and a second vertical plate. Crossbeams are fixedly mounted on both sides of the first and second vertical plates. Grooves are formed on the upper part of each crossbeam, and sliding rods are fixedly mounted within the grooves. Multiple pairs of third side plates and a pair of second side plates are slidably mounted on the two sliding rods. A filter plate is fixed between each pair of third side plates, and a pressing plate is fixed between each pair of second side plates. A thrust plate is fixedly mounted on the inner surface of the first vertical plate. A connecting plate is fixedly mounted on the sliding rods, and a motor is fixedly mounted on the connecting plate. A rotating arm is fixedly mounted at the drive end of the motor, and a rotating hammer is fixedly mounted at the end of the rotating arm. First side plates are fixedly mounted on both sides of the thrust plate, and limiting structures are provided on the outer surfaces of the first, second, and third side plates.

[0006] Furthermore, the limiting structure includes a first rotating plate, which is rotatably connected to the outer surface of the first side plate. A connecting shaft is fixedly provided on the outer surface of the third side plate, and two third rotating plates are rotatably connected to each connecting shaft. A second rotating plate is rotatably provided on the outer surface of the second side plate. The second rotating plate is hinged to an adjacent third rotating plate, and the first rotating plate is hinged to an adjacent third rotating plate. Two adjacent third rotating plates are hinged together.

[0007] Furthermore, the thrust plate is connected to a feed inlet, which penetrates through the first vertical plate.

[0008] Furthermore, the clamping plate is connected to a drain pipe, which passes through the second vertical plate and is slidably connected to the second vertical plate.

[0009] Furthermore, a collection tank is provided below the drain pipe.

[0010] Furthermore, a material collection box is provided below the filter plate.

[0011] Furthermore, a hydraulic cylinder is fixedly installed inside the second upright plate, and the telescopic end of the hydraulic cylinder is fixedly connected to the pressing plate.

[0012] Furthermore, the crossbeam is fixedly provided with support legs on its side wall.

[0013] The beneficial effects of this utility model are: 1. The slurry is injected from the feed inlet. During the filtration process, solid particles are trapped in the filter chamber by the filter plate. The filtrate passes through the filter plate and is discharged from the drain pipe into the collection box. When unloading, the hydraulic cylinder shortens and drives the clamping plate away from the thrust plate. The second rotating plate, the third rotating plate and the first rotating plate work together to drive the filter plate to separate piece by piece. The filter cake falls into the collection box. 2. The centrifugal force generated by the rotation of the hammer can drive the connecting plate to vibrate. The vibration of the connecting plate can drive the slide rod to vibrate. The vibration of the slide rod can drive the filter plate to vibrate. The vibration of the filter plate facilitates the removal of the filter cake attached to the surface of the filter plate.

Limiting structures are provided on the outer surfaces of the first side plates 16, the second side plates 23, and the third side plates 13. The limiting structure includes a first rotating plate 24, which is rotatably connected to the outer surface of the first side plate 16. A connecting shaft 14 is fixedly provided on the outer surface of the third side plate 13, and two third rotating plates 15 are rotatably connected to each connecting shaft 14. A second rotating plate 25 is rotatably provided on the outer surface of the second side plate 23, and the second rotating plate 25 is hinged to an adjacent third rotating plate 15. The first rotating plate 24 is hinged to an adjacent third rotating plate 15, and two adjacent third rotating plates 15 are hinged. A thrust plate 2 is connected to a feed inlet 18, which passes through the first vertical plate 1. A pressure plate 4 is connected to a drain pipe 7, which passes through the second vertical plate 5 and is slidably connected to the second vertical plate 5. A collection box 8 is provided below the drain pipe 7. A collection box 17 is provided below the filter plate 3.
