The specific embodiment
As shown in Figure 1; A kind of automatic separator of coal gangue; It comprises raw material feed hopper 1, coal receiving hopper 2, spoil receiving hopper 3, be arranged on said raw material feed hopper 1 and coal, spoil receiving hopper 2, the conveyer belt conveyer 4 between 3, identification sorting controlling organization, executing agency and be arranged at the queueing mechanism on the conveyer belt, and identification sorting controlling organization comprises the monoenergetic gamma-ray source 6 that is arranged on conveyer belt 5 belows, be positioned at conveyer belt 5 tops corresponding to radiation transducers 7, the measure and control instrument 8 that is electrically connected with radiation transducers 7 of monoenergetic gamma-ray source 6 positions be set in place the ultrasonic transmitter-receiver 9 that is electrically connected with measure and control instrument 8 in conveyer belt 5 tops; Ultrasonic transmitter-receiver 9 can be arranged between radiation transducers 7 and the feed hopper 1 or radiation transducers and receiving hopper between; Executing agency is the high frequency air valve 10 that is arranged on coal, spoil receiving hopper 2,3 tops; The valve port of high frequency air valve 10 leaves the track setting towards coal, spoil. and queueing mechanism is as shown in Figure 2; Comprise the horizon bar 12 that two side stands 11, two ends are connected with two side stands and the queuing plate 14 of band support plate 13; One end of support plate 14 is fixedly connected with the queuing plate; The other end and horizon bar 12 sockets also can be rotated around horizon bar, and the queuing plate 14 of band support plate 13 has four, and queuing plate 14 is the ascending gradually wide plate of width.Like triangle or isosceles triangle, can also be that the width both sides are fusiform gradually wide plate, horizon bar 12 both ends and two side stands 11 are adjustable for height flexible connection.As shown in Figure 2; The district that when coal, spoil are carried, receives four queuing plates on conveyer belt 5 divides into five row at a distance from effect with coal, spoil; And the width of row has different changes along with the difference of triangle queuing plate, thereby changes coal, the regularity of distribution of spoil on conveyer belt.Certainly, the queuing plate 14 of band support plate 13 also can be provided with three, five or more as required.
Secondly, as shown in Figure 3, also can adopt the line-up device that comprises former and later two queueing mechanisms, the queuing plate in the forward and backward queueing mechanism is staggered, and the queuing plate in the forward and backward queueing mechanism is the triangle that drift angle equates.
In addition, can also adopt the queuing system that comprises a plurality of line-up devices, be illustrated in figure 4 as the queuing system that has adopted two line-up devices, the queuing plate of two line-up devices is isosceles triangle, and presses the descending arrangement of throughput direction of conveyer belt by drift angle.The district that when coal, spoil are carried, at first receives preceding four the queuing plates of first line-up device and back five queuing plates on conveyer belt 5 divides into eight row at a distance from effect with coal, spoil; And the width of row has along with blocking of plate of triangle queuing and reduces, and solid matter is pushed be listed as to the monitoring section of central authorities.And then receive second line-up device preceding four the queuing plates and back five the queuing plates the district separated; Because the drift angle of the queuing plate of second line-up device is littler than the drift angle of the queuing plate of first line-up device; As shown in Figure 6; The first big line-up device baffle plate makes little object arrive on the queuing center line earlier, and a big object is arrived near the center line, may some depart from; And then to little that level of baffle plate of second line-up device, as shown in Figure 7, little object bumps less than little baffle plate, and a big object will be fine-tuning on the queuing center line using of little baffle plate.Certainly, line-up device also can be provided with three groups, four groups or more as required, and the number of every group of queuing plate can be provided with as required.
Owing to adopted the monoenergetic gamma-ray source; Has only a kind of nuclear radiation material; The phase mutual interference of multiple spectral lines can not take place in a kind of spectral line of radiation, measures accurately; Sorting effective solved existing automatic separator of coal gangue and measured the inaccurate bad technical problem of separating effect that causes because of the dual intensity gamma-ray source.
After the material of certain particle size was fallen on the conveyer belt 5, material passed monoenergetic gamma-ray source 6 through the arrangement of queueing mechanism, and radiation transducers 7 sends induced signal to measure and control instrument 8.Microprocessor in the measure and control instrument 8 carries out computing with signal according to gangue identification Mathematical Modeling, draws the Density Weighted value of passing the material of monoenergetic gamma rays this moment.This weighted value is compared with the weighted value of setting in advance, is higher than the spoil that is judged as of setting value, is lower than the coal that is judged as of setting value.When being judged as spoil; Behind the delay time through measure and control instrument 8 settings; When spoil left in the process through high frequency air valve 10, measure and control instrument 8 was opened high frequency air valve 10, and gases at high pressure are gone out air valve and hit the spoil in the process of leaving; Make it depart from the original track that leaves, fall into spoil receiving hopper 3.The coal cinder that is not hit is thrown into coal naturally by former track and connects in the bucket 2, thereby realizes the sorting work of coal, spoil.
