Description

Technical Field

[0001] The utility model relates to the technical field of a mining stirring device, in particular to a stirring barrel at the front end of a mining flotation column. Background Art

[0002] In mineral processing operations, a stirring barrel is set at the front end of the flotation column, which is mainly used for stirring before flotation to fully mix the reagent and the slurry. At present, the stirring barrels are all provided with a feed pipe and a discharge pipe. Since the feed is set at a fixed position, the slurry will fall to a position in the stirring barrel during feeding, and it will take more time to mix the materials. In addition, it also takes a lot of time to add reagents and mix them with the slurry. As a result, the stirring time is increased, and the cost of motor power consumption will also increase.

[0003] The existing publication number is CN214487375U, which discloses a flotation tailings defoaming stirring barrel, which specifically includes a barrel body, a feed pipe, a discharge pipe, a transmission device, a first defoaming blade, a second defoaming blade, a centrifugal impeller, a stirring shaft, a slurry pump, a blade needle, blades and a chassis. Although the stirring barrel can defoam, it cannot improve the efficiency of the stirring barrel and reduce the energy consumption of the stirring barrel. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a stirring barrel at the front end of a flotation column for mining.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A stirring barrel at the front end of a flotation column for mining comprises a barrel body, a barrel cover, a motor, a feed pipe and a discharge pipe, wherein a barrel cover is arranged on the top of the barrel body, a motor is arranged on the barrel cover, an output end of the motor passes through the barrel cover and is connected to a stirring shaft in the barrel body, and a stirring blade is arranged on the stirring shaft; a feed pipe and a discharge pipe are arranged on the barrel wall at the upper end and the lower end of the barrel body, respectively; a plurality of evenly distributed shunt feed pipes are arranged on the barrel wall at the upper end of the barrel body, a valve is arranged on the shunt feed pipe, the shunt feed pipe is connected to the shunt pipe, a feed pipe A is arranged on the shunt pipe, and a feed pipe B is arranged at the connection between the feed pipe A and the shunt pipe; the feed pipe A and the feed pipe B can be fed with ore pulp and reagent respectively, or can be fed with ore pulp at the same time.

[0007] The feed pipe includes a feed pipe A, a feed pipe B, a diverter pipe and a diverter feed pipe. The diverter pipe is an arc-shaped pipe. The diverter pipe is connected to the barrel body through a plurality of diverter feed pipes respectively. The feed pipe A and the feed pipe B are arranged in the middle position of the diverter pipe. The slurry and the reagent will be partially mixed in the diverter pipe and enter the barrel body through the diverter feed pipe. The slurry and the reagent will be dispersed into the barrel body and will be mixed in a short time during stirring.

[0008] There are four branch feed pipes, each of which is provided with a valve, which can open or close part of the branch feed pipes as needed.

[0009] The feed pipe A, feed pipe B and discharge pipe are all provided with valves, which can be opened or closed as needed.

[0010] The beneficial effects of the utility model are as follows: two feed pipes are provided, which can respectively feed slurry and reagent, and the two feed pipes are arranged in the middle of the shunt pipe, the slurry and the reagent will be partially mixed in the shunt pipe, and enter the barrel body through the shunt feed pipe, the slurry and the reagent will be dispersed into the barrel body, and then the purpose of mixing will be achieved in a short time during stirring, thereby shortening the stirring time and improving the efficiency of the stirring barrel.
