Description

Technical Field

[0001] This utility model relates to the field of slurry thickener technology, and in particular to a slurry thickener. Background Technology

[0002] Thickeners are suitable for dewatering concentrates and tailings in mineral processing plants and are widely used in metallurgy, chemical industry, coal, non-metallic mineral processing, environmental protection and other industries. In the operation of existing thickeners, after the slurry is poured in from the top of the thickener body, flocculant is added and mixed. After the agitator is started to fully stir, the slurry is dewatered and then the mixture in the slurry is extracted.

[0003] A slurry thickener disclosed in utility model patent application CN220237851U includes a thickening tank with a sedimentation mechanism installed on top. The sedimentation mechanism includes a motor with a shaft at its output end and a rake plate fixedly installed on the side of the shaft. A discharge hopper is installed below the motor, and the discharge hopper is funnel-shaped with a discharge port at its lower end. Several inclined diversion grids are fixedly installed inside the discharge hopper. A first hanger is rotatably installed in the middle of the rake plate, and a second hanger is rotatably installed in the middle of the shaft. The first and second hangers are connected by a connector. The rake plate includes several sets of long rakes and short rakes, and a truss is fixedly connected between the long and short rakes. This invention improves the structure of the discharge hopper to increase the dispersion of the slurry and reduce the impact of the slurry on the material that has already settled at the bottom center of the thickener. Then, by setting up the first hanger, the second hanger, and the truss, the service life of the rake plate is increased. However, this device has the same characteristics as most existing slurry thickeners, that is, during use, the thickened slurry at the bottom of the thickener is discharged from the slurry outlet of the thickener. During the discharge of the slurry, the slurry may block the slurry outlet, and it is inconvenient to manually clear the blockage of the slurry outlet. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a slurry thickener, which can solve the technical problem that this device has the same characteristics as most existing slurry thickeners, namely, during the use of the device, the thickened slurry at the bottom of the thickening tank is discharged from the outlet of the thickening tank. During the discharge of the slurry, the outlet may be blocked by the slurry, and it is inconvenient to manually clear the blockage of the outlet.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a slurry thickener, including a box and a slurry outlet pipe at the lower end of the box. A horizontal plate is fixedly connected to the outside of the slurry outlet pipe, and a vertical plate is fixedly connected to the upper end of the horizontal plate. A horizontal bar is passed through the vertical plate, and an impact block is fixedly connected to one end of the horizontal bar. A protective layer is provided on one side of the impact block, and a spring is fixedly connected between the impact block and the vertical plate. A ring is fixedly connected to the other end of the horizontal bar, and a sliding groove is opened in the ring. A first motor is provided on the horizontal plate, and the output end of the first motor passes through the horizontal plate and is fixedly connected to a cam. One end of the cam is inserted into the sliding groove and contacts the surface of the sliding groove.

[0006] As a preferred embodiment of this utility model, an electric valve is provided on the slurry outlet pipe.

[0007] As a preferred embodiment of this utility model, a bracket is fixedly connected to the upper end of the box, a second motor is provided on one side of the bracket, the output end of the second motor passes through the bracket and is fixedly connected to the stirring rod, and multiple stirring blades are provided on the stirring rod.

[0008] As a preferred embodiment of this utility model, a feed pipe is provided on one side of the box.

[0009] As a preferred embodiment of this utility model, a feeding box is provided at the upper end of the support, and a feeding pipe is provided at the lower end of the feeding box, wherein the feeding pipe passes through the support and extends into the box body.

[0010] As a preferred embodiment of this utility model, a fixing plate is fixedly connected to the outside of the box, and four support legs are fixedly connected to the lower end of the fixing plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by starting the first motor, the rotation of the first motor drives the cam to move in the groove on the ring. When the protrusion on the cam moves to a position away from the end of the crossbar, the spring contracts, and the impact block does not contact the slurry outlet pipe. When the protrusion on the cam moves to a position close to the end of the crossbar, the spring extends and, under the action of the spring force, causes the impact block to strike the slurry outlet pipe. The protective layer on one side of the impact block can provide a certain degree of protection for the slurry outlet pipe. During the continuous rotation of the cam driven by the first motor, the impact block can continuously strike and vibrate the slurry outlet pipe, thereby allowing the blocked slurry to be discharged from the slurry outlet pipe. There is no need for manual cleaning of the slurry outlet pipe, and it can also effectively prevent the slurry outlet pipe from becoming blocked. Attached Figure Description

[0018] Example

[0019] Please refer to Figures 1-3 As shown, this utility model provides a slurry thickener. An electric valve 13 is installed on the slurry outlet pipe 2. A bracket 14 is fixedly connected to the upper end of the housing 1. A second motor 15 is installed on one side of the bracket 14. The output end of the second motor 15 passes through the bracket 14 and is fixedly connected to the stirring rod 16. Multiple stirring blades 17 are installed on the stirring rod 16, and the multiple stirring blades 17 are evenly spaced. A feed pipe 18 is installed on one side of the housing 1. A feeding box 19 is installed on the upper end of the bracket 14, and the feeding box 19 contains flocculant. A feeding pipe 20 is installed at the lower end of the feeding box 19. A switch valve is installed on the feeding pipe 20, and the feeding pipe 20 passes through the bracket 14 and extends into the housing 1. A fixing plate 21 is fixedly connected to the outside of the housing 1, and four support legs 22 are fixedly connected to the lower end of the fixing plate 21.

[0020] During use, slurry can be added into the tank 1 through the feed pipe 18. At the same time, by opening the switch valve on the feed pipe 20, the flocculant in the feed box 19 is fed into the tank 1 through the feed pipe 20 and mixed with the slurry. Simultaneously, the second motor 15 is started, which drives the stirring rod 16 and the stirring blade 17 to rotate together. During the rotation of the stirring blade 17, the slurry and flocculant can be effectively contacted and mixed, thereby achieving slurry concentration. Then, the electric valve 13 on the slurry outlet pipe 2 is opened, which allows the concentrated slurry to be discharged from the slurry outlet pipe 2.

[0021] As a further implementation of this embodiment, such as Figures 1-4 As shown, a horizontal plate 3 is fixedly connected to the outside of the slurry pipe 2, and a vertical plate 4 is fixedly connected to the upper end of the horizontal plate 3. A horizontal bar 5 is passed through the vertical plate 4, and an impact block 6 is fixedly connected to one end of the horizontal bar 5. A protective layer 7 is provided on one side of the impact block 6. The protective layer 7 is made of rubber and can play a certain protective role for the slurry pipe 2. A spring 8 is fixedly connected between the impact block 6 and the vertical plate 4. A ring 9 is fixedly connected to the other end of the horizontal bar 5, and a sliding groove 10 is opened in the ring 9. The surface of the sliding groove 10 is smooth enough. A first motor 11 is provided on the horizontal plate 3. The output end of the first motor 11 passes through the horizontal plate 3 and is fixedly connected to a cam 12. One end of the cam 12 is inserted into the sliding groove 10 and contacts the surface of the sliding groove 10.

[0022] In use, by starting the first motor 11, the first motor 11 rotates and drives the cam 12 to move in the groove 10 on the ring 9. When the protrusion on the cam 12 moves away from the end of the crossbar 5, the spring 8 contracts and the impact block 6 does not contact the slurry outlet pipe 2. When the protrusion on the cam 12 moves close to the end of the crossbar 5, the spring 8 extends and, under the elastic force of the spring 8, the impact block 6 strikes the slurry outlet pipe 2. The protective layer 7 on one side of the impact block 6 can provide a certain degree of protection for the slurry outlet pipe 2. During the continuous rotation of the cam 12 driven by the first motor 11, the impact block 6 can continuously strike and vibrate the slurry outlet pipe 2, thereby allowing the blocked slurry to be discharged from the slurry outlet pipe 2. There is no need for manual cleaning of the slurry outlet pipe 2, and it can also effectively prevent the slurry outlet pipe 2 from becoming blocked.

[0023] Working principle: During use, slurry is added to the tank 1 through the feed pipe 18. Simultaneously, by opening the valve on the feed pipe 20, the flocculant in the feed box 19 is fed into the tank 1 through the feed pipe 20 and mixed with the slurry. At the same time, the second motor 15 is started, driving the stirring rod 16 and stirring blades 17 to rotate together. The rotation of the stirring blades 17 ensures good contact and mixing between the slurry and flocculant, thus achieving slurry concentration. Then, the electric valve 13 on the discharge pipe 2 is opened, allowing the concentrated slurry to be discharged from the discharge pipe 2. If the discharge pipe 2 becomes blocked, the first motor 11 can be started. The rotation of the first motor 11 drives the cam 12 to slide on the ring 9. The cam 12 moves within the groove 10. When the protrusion on the cam 12 moves away from the end of the crossbar 5, the spring 8 contracts, and the impact block 6 does not contact the slurry outlet pipe 2. When the protrusion on the cam 12 moves closer to the end of the crossbar 5, the spring 8 extends and, under the elastic force of the spring 8, the impact block 6 strikes the slurry outlet pipe 2. The protective layer 7 on one side of the impact block 6 can provide some protection for the slurry outlet pipe 2. During the continuous rotation of the cam 12 driven by the first motor 11, the impact block 6 can continuously strike and vibrate the slurry outlet pipe 2, thereby allowing the blocked slurry to be discharged from the slurry outlet pipe 2 without the need for manual cleaning of the slurry outlet pipe 2. At the same time, it can also effectively prevent the slurry outlet pipe 2 from becoming blocked.
