[0002] In the process flow of mining, chemical industry and other fields, there are always operating links where the slurry is divided into two or multiple points. In these links, the uniformity of slurry distribution directly affects the operating effect of downstream equipment.

[0003] In the selection of slurry distribution devices, a relatively simple fixed slurry tank is usually used, which realizes the purpose of material distribution through the bottom opening. This kind of slurry tank often has a large deviation in the amount of slurry entering each distribution point due to the large fluctuation of the feed flow, which leads to different feed amounts of downstream equipment (such as flotation machines, belt filters and hydraulic classifiers, etc.). The models of downstream equipment are generally the same. The difference in feed amount will directly affect the change of downstream equipment operating parameters, which not only affects the complexity of on-site operations, but also destroys the stable and efficient operation of the equipment, thereby affecting the stable operation of the entire production device.

[0004] The present invention provides a non-powered slurry equal distribution device, which drives the impeller in the device to rotate through slurry with a certain flow rate, thereby driving the distribution box, thereby achieving uniform distribution of the slurry, and the device does not require additional electric equipment.

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a non-powered slurry equalization device includes a rotating module 1 and a stationary module 2. The stationary module 2 includes a tank body 21 and a feed pipe 22. The bottom of the tank body 21 is provided with a plurality of discharge ports 23, and the bottom of the tank body 21 is penetrated by the feed pipe 22. The plurality of discharge ports 23 are arranged in a circular array with the central axis of the feed pipe 22 as the center. A plurality of partition baffles 25 are vertically fixed on the inner bottom wall of the tank body 21, and the partition baffles 25 are used to evenly isolate the discharge ports 23. The tank body 21 is cylindrical.

[0024] The rotating module 1 includes a material distribution box 13, a connecting shaft 12, and an impeller 11. The cross-sectional outer contour of the material distribution box 13 is circular, and a plurality of material distribution openings 15 are arranged at the bottom of the material distribution box 13. The plurality of material distribution openings 15 are arranged in a circular array with the central axis of the feed pipe 22 as the center. The impeller 11 is located in the feed pipe 22. The impeller 11 is two curved steel plates, which are wound together on the connecting shaft 12 (such as Figure 4 As shown in the figure, when a slurry with a certain flow rate passes through the impeller 11, the impeller 11 and the connecting shaft 12 are driven to rotate together, and the number of blades on the impeller 11 can be increased according to actual conditions. The connecting shaft 12 is fixed to the impeller 11, and the impeller 11 is fixed to the lower end of the connecting shaft 12. The upper end of the connecting shaft 12 is fixedly connected to the distribution box 13, and the upper end of the connecting shaft 12 is fixed to the distribution box 13 by a thread, and the tightening direction of the thread is consistent with the rotation direction of the impeller 11 to prevent loosening during rotation.

[0025] The material distribution box 13 is located in the tank body 21. A crossbeam is provided on the top of the tank body 21 for mounting the bearing 14. The upper end of the material distribution box 13 is rotatably connected to the tank body 21 through the bearing 14. The bearing 14 needs to be regularly greased to ensure that the rotating part can rotate freely. The upper end of the feed pipe 22 extends into the material distribution box 13. The upper end of the feed pipe 22 is rotatably sealed and connected to the material distribution box 13. The material distribution box 13 and the feed pipe 22 are rotatably sealed and connected to the connecting portion 16. The connecting portion 16 adopts a labyrinth seal, which can effectively reduce slurry leakage.

[0026] An overflow port 24 is provided on the side of the tank body 21, and the height of the overflow port 24 is lower than the height of the material distribution port 15. Specifically, an overflow built-in pipe 26 is fixed on the inner side wall of the tank body 21, and the lower end of the overflow built-in pipe 26 is connected to the overflow port 24, and the upper end opening of the overflow built-in pipe 26 is horizontal, and the upper end opening of the overflow built-in pipe 26 is lower than the height of the material distribution port 15. Due to unstable ore supply, too much slurry enters, and the slurry liquid level will not exceed the bottom of the material distribution box 13, which will affect the rotation of the material distribution box 13. In order to prevent the slurry liquid level from being too high, an overflow port 24 is provided on the side wall of the tank body 21. When the liquid level exceeds the upper end opening of the overflow built-in pipe 26, the slurry will flow out from the overflow port 24, thereby realizing the control of the slurry liquid level. The setting of the overflow port 24 can ensure that the liquid level inside the tank body 21 is not higher than the material distribution port 15, and prevent the material distribution port 15 from contacting the slurry inside the tank body 21 when rotating, thereby increasing the rotation resistance.

[0027] Furthermore, the material distribution opening 15 is curved, and the opening of the material distribution opening 15 faces the side opposite to the rotation direction of the rotating module 1, which is suitable for utilizing the recoil force during material discharge to promote rotation.

[0028] During operation, the feed pipe 22 of the tank body 21 is connected to the external slurry pipeline through a flange, the discharge port 23 is connected to the downstream receiving pipeline through a flange, and the overflow port 24 is connected to the sewage pipeline through a flange. The number of the discharge ports 23 is determined according to the number of downstream receiving points.

[0029] Working principle: When the slurry with a certain flow rate enters from the feed pipe 22, it first passes through the impeller 11 and drives the impeller 11 to rotate. The rotation of the impeller 11 drives the distribution box 13 to rotate together. When the slurry enters the distribution box 13, the slurry rotates with the distribution box 13. Each distribution port 15 of the distribution box 13 continuously transports the slurry to the lower part of the tank body 21. Since the partition baffle 25 evenly isolates the various discharge ports 23, the slurry can be evenly distributed to each discharge port 23, thereby achieving uniform distribution of the slurry.
