Description

technical field

[0001] The invention relates to the technical field of clean coal treatment technology, in particular to a clean coal separation device and a processing method. Background technique

[0002] Curved sieve is a metal mesh structure equipment that can separate solid particles. It has high strength, rigidity and bearing capacity. It is mainly used for pre-dehydration and de-intermediation operations in coal mines.

[0003] Existing reference number is the Chinese patent of CN208853345U, which discloses a curved screen for high-efficiency cleaning of fine magnetism, including a frame and a screen cloth arranged on the frame, and the bottom of the screen cloth is provided with A collection pool for collecting concentrate and water, and a cleaning device for rinsing the screen is provided above the screen; one side of the collection pool is provided with the water in the collection pool to the cleaning device to clean the screen. Water circulation device for cleani...

Examples

Embodiment 1

[0043] refer to figure 1 , is a curved screen 2 with a buffer device disclosed in the present invention, including a frame 1 and a curved screen 2 arranged on the frame 1, and the bottom of the curved screen 2 is provided with a collection of concentrated ore and water The pool 3 and the curved screen 2 are provided with a cleaning device 4 for water supply, and the water outlet of the cleaning device 4 is connected with a buffer box 5, and the buffer box 5 achieves the purpose of improving the separation effect of the curved screen 2.

[0044] refer to figure 1 , when using the curved screen 2, the curved screen 2 is installed on the frame 1, and the collection pool 3 is placed under the curved screen 2, the cleaning device 4 is placed above the curved screen 2, and the buffer The box 5 is placed above the top of the curved screen 2 and the buffer box 5 is connected with the cleaning device 4. After the water flows out from the cleaning device 4, it enters the buffer box 5. ...

Embodiment 2

[0050] A processing method of a clean coal separation device, comprising the following steps:

[0051] S1. Send the raw coal to the first screener for beating salvage and screening, and crush the raw coal going down the beating screen, and add the crushed raw coal and the raw coal directly sieved by the beating screen to the three-product dense medium swirl In the device, clean coal mixed with coal washing medium, medium coal mixed with coal washing medium and gangue mixed with coal washing medium are separated through the three-product dense medium cyclone;

[0052] S2, the clean coal mixed with the coal washing medium, the medium coal mixed with the coal washing medium, and the gangue mixed with the coal washing medium are respectively put into the media removal sieve for media removal to obtain the water-containing clean coal, water-containing coal and water-containing gangue after the media removal, At the same time, the qualified medium is recovered to the mixing tank, an...
