Description

A kind of underground coal spoil Density Separation equipment
Technical field
The utility model relates to a kind of screening installation, especially is applicable to the gangue Density Separation equipment of down-hole coarse coal and gangue sorting on ore deposit.
Background technology
More than 1600 of the existing hillocks of China's coal-mine, approximately 4,500,000,000 tons of accumulating amounts, present annual spoil output is about 200,000,000 tons.It is colliery green exploitation theory important component part that the underground separation of gangue is processed, and the spoil that sub-elects is backfilling goaf directly, reduces the ground spoil and piles up, and can effectively solve the spoil pollution problem in mining area.Gangue underground separation principle mainly is divided into broken and non-broken two kinds.Existing gangue underground separation equipment is mainly the difference according to coal and spoil hardness, first broken the gangue of certain particle size scope, sieve again sorting, make so sometimes the part coal cinder not be broken, sometimes also can make the part spoil be broken, thereby the coal rate of losing of separation results and mixed cash rate are strengthened.Present non-cracking and sorting mainly contains: the sorting of gamma rays method, artificial separation, selection by winnowing, wet concentration etc.The sorting of gamma rays method is mainly different according to gamma rays attenuation in coal and spoil, and then produce the different signals of telecommunication, feed back to executing agency by the signal of telecommunication and change the running orbit of gangue, thereby realize the separation purpose of gangue, but the situation of spoil usually can be wrapped up in down-hole because of coal slime, the method easily causes and falsely drops; Artificial separation is to see by eyes, with hand, from conveyer, picks out the bulk spoil, and the conveyer belt speed on conveyer can not be too large like this, thereby this method workload is large, efficiency is low; Because coal is different with spoil density, selection by winnowing leans on the buoyancy of wind to separate gangue but its dust is larger, and the sorting environment is more poor; Wet concentration separates by buoyancy of water that gangue efficiency is higher but its water consumption is large, cost of investment is high, in the area that water resource lacks, should not promote.Therefore these methods are not suitable for the requirement of down-hole to coal gangues automation selection equipment.Therefore, for adapting to the requirements such as down-hole is simple to device structure, the occupation of land volume is little, in the situation that not broken gangue, the physical characteristic different according to the density of gangue, directly separate with spoil coal.
Summary of the invention
Technical problem: for solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of underground coal spoil Density Separation equipment, realizes that under coal and waste shaft, automation is non-broken apart.
technical scheme: the utility model gangue Density Separation equipment, include hopper, the queuing baffle plate, weighing device, the three-D volumes measuring instrument, baffle plate executing agency, the material ribbon conveyer, fortune cash ribbon conveyer, fortune ribbing formula conveyer, described material ribbon conveyer is arranged in the material bin below with certain inclination angle, fortune cash ribbon conveyer is arranged in bottom, material ribbon conveyer bottom, fortune ribbing formula conveyer is arranged in fortune cash ribbon conveyer left side, material ribbon conveyer top is equipped with many group queuing baffle plates, arrange a quality weighing device between every group of queuing baffle plate, arrange a three-D volumes measuring instrument directly over each quality weighing device, the data that the quality weighing device will record are passed to the corresponding mass sensor by the signal of telecommunication, each three-D volumes measuring instrument and corresponding mass sensor gather the signal of telecommunication respectively the control instrument of passing to corresponding group, judge whether the signal of telecommunication is passed to the baffle plate executing agency that is arranged on queuing baffle plate lower end through the control instrument computational analysis.
Beneficial effect: the utility model can directly separate the coal of bulk in down-hole with spoil, does not need coal and spoil are carried out the Mechanical Crushing sorting, and the efficiency of separation is high, automaticity is high, simple in structure, to take volume little, free from environmental pollution.
Description of drawings
Fig. 1 is main TV structure figure of the present utility model.
Fig. 2 is plan structure figure of the present utility model.
In figure: 1-fortune ribbing formula conveyer, 2-baffle plate executing agency, 3-control instrument, 4-mass sensor, 5-quality weighing device, 6-three-D volumes measuring instrument, 7-queuing baffle plate, 8-material bin, 9-material ribbon conveyer, 10-fortune cash ribbon conveyer.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Underground coal spoil Density Separation equipment of the present utility model, mainly consist of fortune ribbing formula conveyer 1, baffle plate executing agency 2, quality weighing device 5, three-D volumes measuring instrument 6, queuing baffle plate 7, material bin 8, material ribbon conveyer 9, fortune cash ribbon conveyer 10.Described material belt conveying 9 is arranged in material bin 8 belows with certain inclination angle, and fortune cash ribbon conveyer 10 is arranged in material ribbon conveyer 9 bottoms, bottom, and fortune ribbing formula conveyer 1 is arranged in fortune cash ribbon conveyer 10 left sides.Material ribbon conveyer 9 tops are equipped with many group queuing baffle plates 6, arrange a quality weighing device 5 between every group of queuing baffle plate 6, arrange a three-D volumes measuring instrument 6 directly over each quality weighing device 5, the data that quality weighing device 5 will record are passed to corresponding mass sensor 4 by the signal of telecommunication, the mass sensor 4 of each three-D volumes measuring instrument 6 and corresponding group gathers the signal of telecommunication respectively the control instrument 3 of passing to corresponding group, through control instrument 3 computational analysis, judges whether the signal of telecommunication is passed to the baffle plate executing agency that is arranged on queuing baffle plate lower end.
operation principle: material is fallen on material ribbon conveyer 9 by feeding mouth 8, carry out queued packets after queuing baffle plate 7, material ribbon conveyer 9 drives material and transports downwards, when the material cunning is improved quality weighing device 5, quality weighing device 5 and three-D volumes measuring instrument 6 be image data simultaneously, the quality and the volume data that record are gathered the control instrument 3 of passing to corresponding group by the signal of telecommunication, through control instrument 3 computational analysis: if the threshold limit value that the density value that calculates is set greater than coal and spoil, control instrument 3 sends the signal of telecommunication, baffle plate executing agency 2 moves downwards, block spoil, making spoil depart from original movement locus falls on fortune cash ribbon conveyer 10, baffle plate executing agency 2 after the spoil collision gets back to original position immediately, etc. the pending action of the signal of telecommunication next time, if the density value that calculates is in the threshold limit value of coal and spoil setting, control instrument 3 does not send the signal of telecommunication, baffle plate executing agency 2 is action downwards, and coal falls into fortune ribbing formula conveyer 1 by original movement locus, thereby realizes that the down-hole of coal and spoil directly separates.
