Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydrocyclone technology, specifically a hydrocyclone for coal mine flotation. Background Technology
[0002] A hydrocyclone is a common separation and classification device, typically based on the principle of centrifugal sedimentation. When the two-phase mixture to be separated enters the hydrocyclone tangentially from its periphery under a certain pressure, it generates intense three-dimensional elliptical rotational shear turbulence. Due to the size difference between coarse and fine particles, they experience different magnitudes of centrifugal force, centripetal buoyancy, and fluid drag. Under centrifugal sedimentation, most of the coarse particles are discharged through the underflow outlet of the hydrocyclone, while most of the fine particles are discharged through the overflow pipe, thus achieving the purpose of separation and classification.
[0003] However, most common hydrocyclones have overflow pipes with fixed depth and diameter, making it impossible to adjust the overflow pipe according to different grading requirements, resulting in low practicality of the hydrocyclone. Therefore, those skilled in the art have provided a hydrocyclone for coal mine flotation to solve the problems mentioned in the background art. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydrocyclone for coal mine flotation includes a cylindrical cylinder and a conical cylinder, the cylindrical cylinder and the conical cylinder are fixedly connected, a feed pipe is connected to one side of the top of the cylindrical cylinder, an overflow pipe is slidably inserted into the upper end of the cylindrical cylinder, a material gathering cylinder is provided above the cylindrical cylinder, a conical frustum is installed on the upper side wall of the inner cavity of the material gathering cylinder, a discharge port is connected to one side of the material gathering cylinder, a first hydraulic rod is provided between the cylindrical cylinder and the material gathering cylinder, a fixing plate is installed on the outer wall of the overflow pipe, and a second hydraulic rod is connected to the fixing plate.

[0007] Preferably, the upper end of the overflow pipe is slidably inserted into the material collection cylinder, and the upper end port of the overflow pipe is aligned with the conical frustum. Under the extension and retraction of the second hydraulic rod, the conical frustum inside the material collection cylinder can be driven to insert into the upper port of the overflow pipe, thereby changing the discharge port diameter at the overflow pipe outlet port and achieving the function of adjusting the overflow flow rate and particle size.

The smaller end face of the conical truncated cone is aligned with the upper end port of the overflow pipe. A fixing plate is installed on the outer wall of the overflow pipe between the cylindrical cylinder and the collecting cylinder. A second hydraulic rod is installed on the fixing plate. The end of the second hydraulic rod away from the output end is fixedly installed on the inner wall of the collecting cylinder.

The upper end of the overflow pipe 5 is slidably inserted into the material collection cylinder 6. The upper end port of the overflow pipe 5 is aligned with the conical frustum 8. Under the extension and retraction of the second hydraulic rod 11, the conical frustum 8 in the material collection cylinder 6 can be driven to insert towards the upper port of the overflow pipe 5, thereby changing the diameter of the outlet 7 at the outlet port of the overflow pipe 5, so as to adjust the overflow flow and particle size. One end of the first hydraulic rod 9 is fixedly installed on the top side wall of the cylindrical cylinder 1, and the output end of the first hydraulic rod 9 is fixedly installed on the bottom side wall of the material collection cylinder 6.
