Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5The utility model provides a technical solution: a fine tailings filter press drainage mechanism, including a filter press drainage pipe 1, a valve 2, a water delivery cylinder 3, a sealing ring 4, a limiting mechanism 5, a fixing plate 6, a fixing column 7, a connecting plate 8, a fixing groove 9, a fixing cap 10, a filter screen 11, an auxiliary block 12, a connecting groove 13, a fixing rod 14, a movable block 15, a torsion spring 16 and a convex rod 17.

[0029] When using the fine tailings filter press drainage mechanism, if Figure 1 , Figure 2 and Figure 3 As shown, when wastewater is generated after the filter press processes the fine tailings, the filter press drain pipe 1 is connected to the wastewater outlet of the filter press, and a valve 2 is installed in the middle of the filter press drain pipe 1. The filter press drain pipe 1 is plugged into the middle of the water delivery cylinder 3, and is arranged at an equal angle on the outside of the water delivery cylinder 3 in combination with a limiting mechanism 5. The limiting mechanism 5 is used to install and connect the water delivery cylinder 3 and the filter press drain pipe 1. In addition, a sealing ring 4 is provided between the filter press drain pipe 1 and the water delivery cylinder 3. The sealing ring 4 is provided to prevent water leakage at the connection, thereby preventing the wastewater from leaking when it is not treated.

[0030] Open the valve 2 installed in the middle of the filter press drain pipe 1. At this time, the wastewater generated by the filter press flows into the water delivery cylinder 3 through the filter press drain pipe 1, and a connecting groove 13 is installed in the middle of the water delivery cylinder 3. Through the setting of the connecting groove 13, the discharged wastewater can be filtered and then discharged, so as to prevent the direct discharge of wastewater to the outside from causing greater pollution to the environment, thereby having a good protective effect on the environment. The wastewater after the filtration treatment can be discharged outward through the water delivery cylinder 3, and after the filter press has completed the treatment of the fine tailings, all the wastewater is discharged. First, the limit between the water delivery cylinder 3 and the filter press drain pipe 1 is released through the limit mechanism 5. The limit mechanism 5 includes a fixed plate 6 fixedly connected to the outer side of the filter press drain pipe 1, a fixed column 7 for connection, a connecting plate 8 fixedly connected to the outside of the water delivery cylinder 3, a fixed groove 9 provided in the middle of the connecting plate 8, and a fixed cap 10 for locking the limit;

Figure 4 and Figure 5As shown, after removal, by rotating the movable block 15, the movable block 15 and the fixed rod 14 rotate, the torsion spring 16 undergoes elastic deformation, and at this time the movable block 15 drives the protruding rod 17 to rotate in the connecting groove 13, thereby loosening the limit between the protruding rod 17 and the auxiliary block 12, and then by pulling the filter screen 11, the filter screen 11 drives the auxiliary block 12 to disengage from the protruding rod 17, and the protruding rod 17 slides out from the opening of the connecting groove 13, so that the filter screen 11 can be disassembled, cleaned or replaced very conveniently, and the filter screen 11 can be prevented from being blocked after long-term use, which affects the actual filtering effect, and it is very convenient to use.
