Problems solved by technology

[0002] At present, the jigging coal separation method and the gangue jigging machine used for coal preparation at home and abroad are like pages 192 to 226 of the book "Mineral Processing" published by the China University of Mining and Technology Press in October 2002. The traditional single-stage jig and its coal preparation method contained in the book "Coal Preparation Handbook" published by China Coal Industry Press in April 1993 on pages 329-435, and the State Intellectual Property Office of China on August 16, 2006 The published invention patent application CN 1817469A contains a jigging gangue removal coal preparation method and a gangue jigging machine, both of which have the discharge of heavy products and under-screen sieve products that are combined in the body and discharged from the same discharge port. It is this feature that prevents the sieve products and heavy products from being separated into gangue products in the discharged products, and when the ash content of the sieve products is not high or there is no high requirement for the ash content of the concentrate, the sieve products should be combined with The light products are mixed into concentrated ore products, so the existing technology causes the loss of these intermediate products through sieving, and there is a phenomenon of medium coal or a small amount of clean coal in the gangue, which affects the recovery rate and increases the loss.

Embodiment 1

[0040] Embodiment 1, in Fig. 1, an air chamber gangue discharge jig with an independent gangue discharge channel, it includes the existing gangue discharge jig machine body 1 and an independent gangue discharge channel 9, the gangue discharge channel 9 It is a closed device with upper and lower openings. It is composed of an upper gangue inlet 15, a gangue discharge device 8, a connecting channel 16 and a lower gangue discharge outlet 11. The gangue inlet 15 of the gangue discharge channel 9 and the gangue discharge device 8 are all exactly the same as the body structure of the existing gangue-discharging jig machine, and the connecting channel 16 is drawn outwards through the body wall, and the end is provided with a gangue discharge port 11. The connecting channel 16 can be straight, can also be made into various bends, can also be made into oblique or other forms, and the section can be rectangular, circular, or other shapes .

Embodiment 2

[0042] Embodiment 2, in Fig. 2, the second type of air chamber gangue discharge jig with independent gangue discharge channel, the shape, structure, materials used, functions, etc. of the gangue discharge jig body 1 are as described in embodiment 1 . The main shape, structure, materials used, and functions of the gangue discharge channel 9 are also as described in Embodiment 1, the difference is that a discharge height adjustable discharge height is installed on the clean coal inlet 3 Regulator 14.

[0043] When this embodiment is working, the working steps, methods, principles, etc. are as described in Embodiment 1, the difference is that the ash content of the discharged clean coal is controlled to a certain extent through the installed discharge height adjusting device 14 that can adjust the discharge height. Achieve on-demand nesting.

Embodiment 3

[0044] Embodiment 3, in Fig. 3, the third type of air chamber gangue ejection jig with independent gangue ejection channel, the shape, structure, materials used, functions, etc. of the gangue ejection jig body 1 are as described in embodiment 1 . The main shape, structure, materials used, and functions of the gangue discharge channel 9 are also as described in Embodiment 1, the difference is that an automatic float discharge device is added above the discharge end of the gangue discharge jig body 1 13.

[0045] Based on the same principle and method, the present invention can also realize the structure and function as shown in FIG. 3 on the gangue-discharging jig as described in Embodiment 2.

[0046] When the present embodiment works, the working steps, methods, principles, etc. are as described in Embodiment 1, the difference is that the floating objects such as wood slag floating on the water surface are discharged by the installed floating object automatic discharge devic...
