Jigging machine with entered material pretreatment function

Abstract

The invention discloses a jigging machine with an entered material pretreatment function. The jigging machine with the entered material pretreatment function comprises an existing jigging machine. A coal distribution and wetting device is designed on a material inlet of the jigging machine and is composed of a material entering hopper, a water injection device and a coal distribution stirring device. The width of the material entering hopper is equal to that of the jigging machine, openings are formed in the top and the bottom of the material entering hopper, two transverse sides of the material entering hopper are perpendicular to one side of the front end of the material entering hopper, and one side of the rear end of the material entering hopper is in an inclined box-type structure. The water injection device is horizontally arranged on the top of the material entering hopper. By means of the using of the jigging machine with the entered material pretreatment function, the fact that the entered materials can be simply and effectively conducted effective material distribution and wetting treatment when the entered materials are washed is achieved in one equipment, and the functions of buffering and dust eliminating to the entered materials can be achieved, so that the effects that the number of the equipment is reduced, processing capacity is improved, equipment failure rate is reduced, water consumption is reduced, floor space is reduced, total investment is reduced, elevation loss is reduced, and the like are achieved. The jigging machine with the entered material pretreatment function is especially suitable for steam coal waste rock discharging, lump coal washing, and fine coal washing.

Description

Technical field [0001] The invention relates to a coal preparation equipment, in particular to a jig with the function of feeding pretreatment. Background technique [0002] At present, the jigging machines used at home and abroad do not have the function of feeding pretreatment. As stated on pages 196-226 of the book "Mineral Processing" published by China University of Mining and Technology Press in October 2002, these jigging machines The feeding of the machine is required to be uniform and stable, and it needs to be moistened with water, otherwise there will be agglomeration and bed instability during the coal washing process, especially when the fine coal content is large, the agglomeration will seriously affect the coal washing accuracy. For this reason, the measure of adding a coal feeder before the jig is often used in the process design to solve this problem. As a result of this, there are more links in the process, increased elevation loss in the factory building,...

AI Technical Summary

Problems solved by technology

As a result of this, there are more links in the process, an increase in the elevation loss in the factory building, an increase in the floor space of the workshop, an increase in system investment, and an increase in the failure rate of equipment

Moreover, because the current coal feeder technology has not been perfected, most of the coal feeders in use are not effective, and the pretreatment effect is mostly not up to the desired requirements.

In addition, in the steel structure factory building, since the foundation of all equipment is on the ground and there is no floor, the coal feeder needs to be installed at a higher place, and a higher support is set up, which brings about difficulties in installation on the one hand, and on the other hand In the case of using a vibrating coal feeder, the problems of support vibration and loud noise are not easy to solve
