[0006] The bottom ore discharging device of a thickener includes a vertical pipe fixedly connected to the bottom of the thickener. A horizontal pipe is provided at the lower half of one side of the vertical pipe. A positioning groove is formed in the lower half of the side wall of the vertical pipe, and a through hole is formed in the inner side wall of the positioning groove. A fixing ring is fixedly sleeved on the outer peripheral surface of the horizontal pipe. The fixing ring is inserted into the positioning groove, and the horizontal pipe slides through the through hole. One side wall of the fixing ring is attached to the inner side wall of the positioning groove, and the other side wall of the fixing ring is coplanar with the side wall of the vertical pipe. A rotating ring is rotatably connected to the side wall of the vertical pipe outside the fixing ring. A fixing part is arranged inside the rotating ring, and a driving part is arranged outside the rotating ring.

[0007] Furthermore, the fixing part includes three convex blocks uniformly and fixedly connected to the inner peripheral surface of the rotating ring. A gap is left between adjacent two convex blocks. Three support plates are fixedly connected to the side wall of the vertical pipe. A sliding plate slidably penetrates through one side of the support plate. One side of the sliding plate is attached to the side wall of the fixing ring. A wedge-shaped block is fixedly connected to the side of the sliding plate close to the rotating ring. The wedge-shaped block is attached to the corresponding convex block. A spring is fixedly connected between the wedge-shaped block and the corresponding support plate. The spring is in a compressed state.

[0008] Further, the driving part includes a fixing frame fixedly connected to the side wall of the vertical pipe. The fixing frame is L-shaped, and a motor is fixedly connected to the inner side wall of the fixing frame. The output end of the motor is drivingly connected to a lead screw. A driving gear is fixedly sleeved on the outer peripheral surface of the lead screw, and a driven gear is fixedly sleeved on the outer peripheral surface of the rotating ring.

Detailed implementation mode

[0021] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0022] Embodiment:

[0023] Referring to Figures 1 to 5 , the bottom ore discharging device of the thickener disclosed by the present utility model includes a vertical pipe 1 fixedly connected to the bottom of the thickener. A horizontal pipe 2 is provided at the lower half of one side of the vertical pipe 1. A positioning groove 3 is opened on the lower half of the side wall of the vertical pipe 1. A through hole 4 is opened on the inner side wall of the positioning groove 3. A fixing ring 5 is fixedly sleeved on the outer peripheral surface of the horizontal pipe 2. The fixing ring 5 is inserted into the positioning groove 3, and the horizontal pipe 2 slides through the through hole 4. One side wall of the fixing ring 5 is attached to the inner side wall of the positioning groove 3, and the other side wall of the fixing ring 5 is coplanar with the side wall of the vertical pipe 1. A rotating ring 6 is rotatably connected to the side wall of the vertical pipe 1 outside the fixing ring 5. A fixing part 7 is arranged inside the rotating ring 6, and a driving part 8 is arranged outside the rotating ring 6.

[0024] In this embodiment, the ore pulp discharged from the thickener directly enters the vertical pipe 1 and then is discharged through the horizontal pipe 2. The ore pulp is likely to adhere to the inner bottom wall of the vertical pipe 1. The outer peripheral surface of the fixing ring 5 is attached to the inner wall of the positioning groove 3.

[0025] In the initial state (as shown in Figure 2 ), the horizontal pipe 2 and the vertical pipe 1 are in a fixed state. When the rotating ring 6 rotates, the fixing state of the horizontal pipe 2 can be released through the fixing part 7, so as to realize the separation of the horizontal pipe 2 and the vertical pipe 1, which is convenient for the staff to clean the accumulated ore adhering to the inner bottom wall of the vertical pipe 1 through the through hole 4.

[0026] In a further preferred embodiment of the present utility model, as shown in Figure 2 , 3 and Figure 4As shown, the fixing part 7 includes three bumps 71 uniformly and fixedly connected to the inner peripheral surface of the rotating ring 6, with gaps left between adjacent bumps 71. Three support plates 72 are fixedly connected to the side wall of the vertical pipe 1. A sliding plate 73 is slidably inserted through one side of the support plate 72. One side of the sliding plate 73 is in contact with the side wall of the fixed ring 5. A wedge block 74 is fixedly connected to the side of the sliding plate 73 close to the rotating ring 6. The wedge block 74 is in contact with the corresponding bump 71. A spring 75 is fixedly connected between the wedge block 74 and the corresponding support plate 72. The spring 75 is in a compressed state.

[0027] In this embodiment, in the initial state, the bump 71 presses the wedge block 74, causing part of the sliding plate 73 to be in contact with the outer wall of the fixed ring 5. Therefore, the fixed ring 5 cannot be pulled out of the positioning groove 3, and the fixed ring 5 and the horizontal pipe 2 are fixed to the vertical pipe 1. Both opposite sides of the wedge block 74 are inclined, and both opposite sides of the bump 71 are also inclined (as Figure 2 shown).

[0028] When it is desired to remove the fixed ring 5 and the horizontal pipe 2, the driving part 8 operates to drive the rotating ring 6 to rotate. The rotating ring 6 drives the bump 71 to rotate. The bump 71 moves relative to the wedge block 74 until the wedge block 74 is aligned with the space between the two bumps 71. The wedge block 74 moves in the direction away from the fixed ring 5 under the restoring force of the spring 75. Therefore, the sliding plate 73 no longer contacts the fixed ring 5. At this time, the fixed ring 5 can be pulled out of the positioning groove 3, and then the horizontal pipe 2 can be pulled out of the through hole 4, and then the accumulated ore attached to the inner bottom wall of the vertical pipe 1 can be cleaned through the through hole 4.

[0029] In a further preferred embodiment of the present utility model, as Figure 1 shown, the driving part 8 includes a fixing frame 81 fixedly connected to the side wall of the vertical pipe 1. The fixing frame 81 is L-shaped. A motor 82 is fixedly connected to the inner side wall of the fixing frame 81. The output end of the motor 82 is drivingly connected to a lead screw 83. A driving gear 84 is fixedly sleeved on the outer peripheral surface of the lead screw 83. A driven gear 85 is fixedly sleeved on the outer peripheral surface of the rotating ring 6. The driving gear 84 meshes with the driven gear 85.

[0030] In this embodiment, the motor 82 operates to drive the lead screw 83 to rotate. The lead screw 83 rotates to drive the driving gear 84 to rotate. The driving gear 84 drives the driven gear 85 to rotate. The driven gear 85 drives the rotating ring 6 to rotate.

[0031] In a further preferred embodiment of the present utility model, as Figure 1 and Figure 5As shown, a baffle 9 is threadedly connected to the outer peripheral surface of the lead screw 83. The baffle 9 slidably passes through the side wall of the vertical pipe 1, and both the front and rear side walls of the baffle 9 are in contact with the inner wall of the vertical pipe 1. A flexible hose 10 is fixedly penetrated through the side wall of the vertical pipe 1 above the baffle 9. One end of the flexible hose 10 away from the vertical pipe 1 communicates with the horizontal pipe 2. A first valve 11 is fixedly sleeved on the outer peripheral side of the flexible hose 10. A second valve 13 is fixedly sleeved on the outer peripheral side of the horizontal pipe 2 between the fixed ring 5 and the flexible hose 10.

[0032] In this embodiment, in the initial state, the first valve 11 is in the closed state, the second valve 13 is in the open state, and one side of the baffle 9 located inside the vertical pipe 1 is in contact with the inner wall of the side of the vertical pipe 1 close to the fixing frame 81 (as Figure 5 shown). At this time, the pulp can only be discharged through the horizontal pipe 2 and the second valve 13.

[0033] When the motor 82 works and releases the fixed state between the fixed ring 5 and the vertical pipe 1, the lead screw 83 rotates and drives the baffle 9 to insert into the vertical pipe 1, and finally completely shields the inside of the vertical pipe 1, preventing the pulp from moving below the baffle 9. At the same time, the first valve 11 is opened and the second valve 13 is closed. The pulp discharged from the thickener will enter the horizontal pipe 2 through the flexible hose 10 and the first valve 11. Therefore, when there is accumulated ore at the inner bottom wall of the vertical pipe 1, it is not necessary to stop the thickener, improving the working efficiency of the thickener.

[0034] The flexible hose 10 can be bent and deformed, so the flexible hose 10 will not hinder the horizontal pipe 2 from being pulled out of the through hole 4.

[0035] In a further preferred embodiment of the present invention, as Figure 1 shown, two avoidance openings 12 are formed in the outer wall of the rotating ring 6 between the convex block 71 and the driven gear 85.

[0036] In this embodiment, the formation of the avoidance openings 12 facilitates the staff's arm to pass through the avoidance openings 12 and then through the through hole 4 to clean the accumulated ore on the inner bottom wall of the vertical pipe 1.

[0037] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
