Problems solved by technology

This technology brings the following problems: ①The system investment is large, and the total cost of the actual bucket elevator has exceeded the cost of the jig; ②The system occupies a large area, and the area occupied by the bucket elevator is much larger than that of the jig The main body occupies an area; ③The upper limit of the washing particle size is reduced, because the bucket elevator has requirements on the lumpiness of the material, so the upper limit of the washing particle size of the jig is limited; ④The energy consumption is large, and the total power of the bucket elevator Larger results; ⑤Increase in system failure and maintenance

Embodiment 1

[0027] Embodiment 1, in Fig. 1, a kind of gangue-discharging jig machine with lifting wheel discharging, it comprises existing gangue-discharging jig machine body 1 and lifting wheel discharging device 15, described lifting wheel discharging device 15 consists of Clean coal lifting wheel 11, gangue lifting wheel 12, lifting wheel driving device 17, clean coal discharge chute 13, gangue discharge chute 14, clean coal discharge channel 9, gangue discharge channel 10, material guide plate 19, material guide The sieve plate 20 and the shell are composed of parts. Wherein: the clean coal lifting wheel 11 and the gangue lifting wheel 12 are existing conventional technologies; the lifting wheel driving device 17 is a friction wheel driving device, and this device can also adopt other forms mature in the existing coal preparation machinery Friction wheel drive device; gangue-discharging jig machine body 1 introduces clean coal products and gangue products to the lower part of clean co...

Embodiment 2

[0029] Embodiment 2, in Fig. 2, the second type of gangue-discharging jig with a lifting wheel for discharge, the internal structure, materials used, functions, etc. of the gangue-discharging jig are as described in Embodiment 1. The internal structure, materials used, functions, etc. of the lifting wheel discharge device 15 are also as described in Embodiment 1. The difference is that the lifting wheel discharge device 15 and the shell of the jig machine body 1 are integrated, the miscellaneous discharge port 18 of the lifting wheel discharge device is canceled, and a unified sediment collection bucket is established, so that the lifting wheel discharges A small amount of debris deposited in the device directly enters the sediment collection hopper and is discharged through the undersize discharge port 16.

[0030] When this embodiment is working, the working steps, methods, principles, etc. are as described in Embodiment 1, the difference is that a small part of debris that ...

Abstract

The invention is concerned with the dumping gangue jigger using elevating wheel to dump, includes the existing dumping gangue jigger, the elevating wheel dumping equipment setting at the dumping end of the dumping gangue jigger, which uses the equipment to dump the gangue produce and the coal produce on the sieve after dehydration. The invention can reduce the system investment and the system occupied square, increase the upper limit of wash granularity. The invention can be use for pre-dumping gangue, recycle coal in the mixed coal, dump gangue under well.

Description

Technical field [0001] The invention relates to a coal preparation equipment, in particular to a gangue-discharging jig machine which uses a lifting wheel to discharge materials. Background technique [0002] At present, the air pulsation jig used for coal preparation at home and abroad is like the 192-226 pages of the book "Mineral Processing" published by China University of Mining and Technology Press in October 2002, and China Coal Industry Press in 1993. The traditional single-stage jig machine contained in pages 329-435 of the "Coal Preparation Handbook" published in April 2006, and the species jigging machine contained in the public number 1817469A published by the State Intellectual Property Office of China on August 16, 2006 The gangue removal coal preparation method and the gangue removal jigging machine all use the layout of the outside of the jig machine body to connect two bucket elevators to form a system. This technology brings the following problems: ①The sy...
