Description

Technical Field

[0001] The utility model relates to the technical field of three-product heavy medium cyclones, in particular to a three-product heavy medium cyclone with a flow guide structure. Background Art

[0002] The three-product heavy medium cyclone is composed of a first-stage cyclone and a second-stage cyclone connected in series. In the heavy medium cyclone sorting process, the sorting in the first-stage cyclone is the main sorting, and a low-density suspension is used for sorting. The material and the suspension are fed into the cyclone at a certain pressure to form a strong vortex flow; the liquid flow starts from the feed port and forms a descending outer spiral flow along the inner wall of the first-stage cyclone; after the clean coal is sorted out, the medium coal and gangue are introduced into the second-stage cyclone through the connecting pipe. At the same time, due to the concentration of the suspension in the first stage, a high-density suspension is prepared for the second stage; the sorting in the second-stage cyclone is the secondary sorting, and two products, medium coal and gangue, are sorted out. For example, the authorization announcement number "CN220657872U" is a three-product heavy medium cyclone with a diversion structure, whose structure includes a first-stage cyclone and a second-stage cyclone, and the first-stage cyclone The interior of the device is a hollow structure. One end of the first-stage cyclone is fixedly connected to an overflow pipe. The end of the overflow pipe is fixedly connected to an overflow connector. The bottom of the overflow connector is fitted with a guide pipe A connector. The bottom of the guide pipe A connector is fixedly connected to the guide pipe. A spiral rod is fixedly connected to the inside of the guide pipe. The spiral rod passes through the outside of the guide pipe. The end of the spiral rod is rotatably connected to a motor. The outside of the motor is fixedly connected to a bracket, which is fixed to one end of the guide pipe. The spiral rod and rotating blades are provided inside the guide pipe, so that the mixture in the overflow pipe is rotated by the rotating blades and transferred from the overflow pipe to the inside of the second-stage cyclone, preventing the mixture from accumulating in the connecting pipe and clogging the pipe.

[0003] When the three-product heavy medium cyclone is in use, the mined coal is added to the cyclone. The spiral rod and rotating blades installed inside the guide pipe allow the mixture in the overflow pipe to be evenly transferred from the overflow pipe to the second-stage cyclone through the rotation of the rotating blades, thereby preventing the mixture from accumulating in the connecting pipe and improving the separation efficiency.

[0004] During the use of traditional three-product heavy medium cyclones, the mined coal is directly added to the cyclone for screening. Since the mined coal is large in volume, the cyclone does not crush the coal. When the large coal enters the cyclone, it will cause blockage inside the cyclone, thereby reducing the coal screening efficiency. Utility Model Content

The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0021] In traditional three-product heavy medium cyclones, mined coal is directly added to the cyclone for screening. Due to the large volume of mined coal, the cyclone does not crush the coal.

[0022] In view of this, the utility model provides a three-product heavy medium cyclone with a guide structure. The ore enters the interior of the device shell from the feed port and is crushed by the crushing device. After the ore is crushed, it passes through the storage box and enters the interior of the cyclone. Since the crushed ore is smaller, it will not cause blockage inside the cyclone after entering the cyclone, thereby improving the coal screening efficiency.
