Description

Technical Field

[0001] The utility model relates to the technical field of flotation machines, in particular to a slurry mixing barrel for a flotation machine. Background Art

[0002] Slurry adjustment is an important pretreatment step before flotation. The effect of slurry adjustment will directly affect the subsequent flotation results and determine the concentrate yield and economic benefits of the beneficiation plant. Slurry adjustment before flotation can achieve the dispersion of insoluble reagents and mineral particles and the suspension of coarse particles, and at the same time can achieve the spreading of reagents on the surface of mineral particles. The strengthening of the slurry adjustment process is of great significance to the entire mineral sorting, especially the sorting of fine particles and difficult-to-float minerals. In the existing technology, when the slurry stirring tank is used for the flotation of coarse-grained sulfide ores, due to the coarse particle size of the flotation feed, the stirring tank is prone to sedimentation, resulting in uneven blending of the slurry and reagents. This is mainly because the slurry rotates as a whole in the tank, the internal mixing of the slurry is not uniform, and the upper and lower stratification is more serious, which in turn causes sedimentation in the stirring tank. In addition, the stirring barrel in the existing technology is uneven when distributing the material.

[0003] A search of patent publication number CN221868236U, entitled "A Slurry Mixing and Stirring Device," revealed a slurry mixing and stirring device, specifically disclosing a slurry mixing and stirring device comprising a mixing barrel, mounted with a feed pipe, a discharge pipe, and an overflow pipe. A fixed ring is secured to the outer top of the mixing barrel, a support frame is mounted on top of the fixed ring, a mixing assembly (I) is mounted at the center of the support frame, and multiple mixing assemblies (II) are positioned around the mixing assembly (I). A guide barrel is positioned within the mixing barrel, a guide plate is positioned at the bottom of the inner side of the guide barrel, and a discharge chute is positioned between the guide plate and the guide barrel. Furthermore, the support frame is a cross-shaped structure. Furthermore, the mixing assembly (I) comprises a mixing shaft (I), which is rotatably mounted on the support frame via a mounting bracket (I), and an impeller is mounted at its bottom, the impeller having multiple blades. Four mixing assemblies (II) are provided, each comprising a mixing shaft (II), which is rotatably mounted on the support frame via a mounting bracket (II), and multiple stirring rods are mounted on the mixing shaft (II). Furthermore, a motor driving agitator shaft 1 is mounted on the top of the support frame via a motor mount. A belt drive mechanism connects agitator shaft 1 to a single agitator shaft 2, and between each two agitator shafts 2. Furthermore, agitator assembly 1 is located inside the diversion barrel, and four agitator assemblies 2 are evenly distributed outside the diversion barrel. Furthermore, the discharge end of the feed pipe extends above the diversion barrel. Furthermore, the diversion plate is a conical structure, and multiple support rods are provided between the diversion plate and the diversion barrel.

[0004] By analyzing the above-mentioned public materials, it can be known that the slurry can be effectively prevented from being separated into upper and lower layers and the sedimentation of the mixing tank can be avoided. However, there are still some shortcomings in the convenience of stirring, and unevenness will occur. In addition, the distribution method of the feed pipe will also cause unevenness of the blades during stirring. Utility Model Content

[0005] In view of this, the utility model provides a slurry mixing barrel for a flotation machine, which can not only solve the problem of uneven mixing, but also ensure uniform distribution of materials and full coordination of various components.

[0006] In order to solve the above technical problems, the utility model provides a slurry mixing barrel for a flotation machine, comprising a barrel body, a fixing frame is provided on the upper end surface of the barrel body, a motor is provided on the fixing frame, the motor is connected to a stirring shaft connected to the fixing frame via a bearing via a belt, the stirring shaft extends into the barrel body, and further comprises:

[0007] A diversion barrel, the diversion barrel is connected to a stabilizing frame and fixed inside the barrel body through the stabilizing frame. The diversion barrel is divided into an upper diversion barrel and a lower diversion barrel;

[0009] The axial flow impeller blades are arranged in the guide upper barrel, and the radial flow impeller blades are arranged below the guide lower barrel;

[0010] The material distribution component includes a material distributor arranged inside the barrel body, the material distributor is arranged above the diversion upper barrel, and the material distributor is connected to the material inlet pipe.

[0011] Furthermore, the diversion upper barrel and the diversion lower barrel are aligned vertically and arranged in the middle position of the cylinder. The upper end of the diversion upper barrel is a bell-mouth structure for receiving materials falling from the distributor.

[0012] Furthermore, the stabilizing frame is in the shape of a circular ring and is used to connect the diversion upper barrel and the diversion lower barrel, and the stabilizing frame is fixed to the inner wall of the cylinder through a rod.

[0013] Furthermore, a guide lower barrel seat is provided below the guide lower barrel, and a partition is provided between the guide lower barrel and the guide lower barrel seat.
