Description

Technical Field

[0001] The utility model belongs to the technical field of mineral processing equipment, in particular to an automatic rotating slurry divider. Background Art

[0002] In the mineral processing process, the slurry transportation connection between upstream and downstream process sections usually requires the slurry to be distributed and diverted so that it can be distributed to multiple groups of equipment simultaneously. Therefore, the uniformity and stability of the slurry distribution are required. If the slurry is not evenly distributed, it will seriously affect the performance and efficiency of subsequent equipment. For example, the use of gravity separation equipment such as spiral chutes and shaking tables generally has a large number of devices and usually requires the slurry to be supplied by separators. However, the design of ordinary separators is unreasonable, which can easily cause turbulence, uneven ore feeding, and mineral particle deposition, which can cause blockage in the ore separation pipeline. This leads to inconsistent feed amount and feed concentration to the spiral chute or shaking table, resulting in unstable sorting indicators.

[0003] To solve this problem, commonly used methods include installing a stirring device or pressurizing the separator, but these methods either consume electricity, increasing production costs; or complicate the structure of the separator, increasing the difficulty of processing and maintenance costs of the separator.

Each discharge chamber is provided with a discharge pipe.

[0022] The present invention is further described in detail based on the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figure 1-5An automatic rotating slurry divider shown includes a feed pipe 1, a distribution box 2 and a discharge box 7. The feed pipe 1 is arranged above the distribution box 2. The inner wall of the distribution box 2 is provided with a number of blades 3, a collecting funnel 4 and a distributor 5 from top to bottom. The distributor 5 is connected to the bearing 6, the bearing 6 is rotatably connected to the bearing base 12, and the bearing base 12 is fixedly connected to the bottom plate of the discharge box 7. A number of distribution pipes 8 are provided at the bottom of the side wall of the distribution box 2, and the outlet of the distribution pipe 8 is located inside the discharge box 7.

[0025] Furthermore, the blades 3 form an angle of 45-60° with the inner wall of the ore distribution box 2, so that the gravity potential energy and the falling potential energy of the inflowing slurry can impact the blades 3 to generate thrust to drive the ore distribution box 2 to rotate.

[0026] Furthermore, the distribution pipe 8 and the horizontal plane of the distribution box 2 form an angle of 15-30 degrees, so that the slurry flowing out of the distribution pipe 8 can generate a reaction force to drive the distribution box 2 to rotate.

[0027] Furthermore, the blades 3 and the distribution pipe 8 are staggered in a top view, which more reasonably distributes the directions of the thrust and reaction force so that the directions of the thrust are consistent.

[0028] Furthermore, the bottom plate of the discharge box 7 is tilted toward the center, forming an angle of 15-30° with the horizontal plane, and the gravity potential energy is used to make the slurry flow toward the edge of the discharge box 7 and enter the discharge pipe 11 to prevent the slurry from being blocked.

[0029] Furthermore, a plurality of partitions 9 are provided on the bottom plate of the discharge box 7. The partitions 9 are arranged along the central circumference of the discharge box 7 to divide the interior of the discharge box 7 into a plurality of discharge chambers 10. The discharge chambers 10 are each provided with a discharge pipe 11. Each discharge chamber 10 and the discharge pipe 11 corresponds to a chute or shaking table for feeding ore.

[0030] Furthermore, the discharge pipe 11 forms an angle of 15-30° with the horizontal plane, and utilizes gravity potential energy to make the slurry flow into the chute or shaking table to prevent slurry blockage.

[0031] The above-mentioned device is used in the following process: the slurry is obliquely fed into the distribution box 2 through the feed pipe 1, and falls to impact the blades 3 by relying on the gravitational potential energy and kinetic potential energy, providing a driving force for the blades 3. The turbulent slurry is collected by the collecting funnel 4 and falls along the middle axis to the distributor 5, and is evenly dispersed by the distributor 5 into the distribution pipe 8 at the bottom thereof. The slurry flows out from the distribution pipe 8 and is fed into the discharge chamber 10, and at the same time provides a counter-thrust force to act on the distribution pipe 8, which forms a combined force with the thrust of the blades 3 to form a driving force for the rotation of the distribution box 2, so that the distribution box 2 rotates automatically and quickly, and then the distribution pipe 8 feeds the slurry into the discharge chamber 10 in sequence, and then flows out through the discharge chamber 10 and the discharge pipe 11 to be transported to the chute through the connecting pipe of the chute.
