Abstract
Description
Technical Field
[0001] This utility model relates to a slurry mixing tank, belonging to the field of vanadium-titanium magnetite beneficiation equipment. Background Technology
[0002] In the process of mixing slurry in the beneficiation of vanadium-titanium magnetite, the existing slurry mixing tanks have an impeller axis that coincides with the tank body axis, meaning the impeller is located in the middle of the tank. This structure actually creates a vortex above the impeller during the rotation of the impeller, resulting in uneven mixing and insufficient mixing of the reagents and slurry in the tank, high energy consumption, and low mixing efficiency, which increases production costs. Utility Model Content
[0003] The technical problem to be solved by this utility model is that existing slurry mixing tanks are prone to generating vortices, resulting in uneven mixing and insufficient mixing of reagents and slurry, high energy consumption and low mixing efficiency.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a slurry mixing tank, including a tank body and a stirring impeller, wherein the stirring impeller is eccentrically arranged in the tank body, and a guide plate is provided on the inner wall of the tank body away from the stirring impeller.
[0005] In the aforementioned device, the guide plate is provided with guide holes at intervals.
[0006] The device also includes an adjustment plate, one end of which is connected to the inner wall of the guide hole away from the stirring impeller, and the other end is spaced apart from the guide hole.
[0007] In the aforementioned device, at least two guide plates are arranged at intervals along the circumferential direction of the inner wall of the barrel.
[0008] In the aforementioned device, the guide plate is arranged in at least two layers at intervals along the vertical axis of the barrel.
[0009] The stirring impeller in the above-mentioned device is a double-layer radial impeller structure.
[0010] In the above-mentioned device, the distance between the axis of the stirring impeller and the axis of the barrel is 10-20cm.
[0011] The device described above has a feed pipe on the lower side wall of the barrel and a discharge pipe on the upper side wall.
[0012] The beneficial effects of this invention are as follows: This device changes the traditional method of slurry mixing. The eccentrically mounted impeller alters the slurry's flow pattern during mixing, reducing vortex generation and thus increasing turbulence, improving mixing efficiency, and reducing energy loss. The guide plates installed on the cylinder wall improve the slurry's flow state within the cylinder, preventing dead zones and ensuring thorough mixing and reaction of materials. Simultaneously, they disperse the slurry's flow, reduce the rate of liquid level drop, maintain slurry stability and consistency, and improve mixing efficiency. This reduces the impact of vortices on the impeller, increases mixing efficiency, reduces energy loss, and lowers costs. Attached Figure Description
