Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following describes a method and an apparatus for recycling mixed solid waste provided by the present invention in detail with reference to the following embodiments. The following examples are intended to illustrate the invention only and are not intended to limit the scope of the invention.
Principle for setting breaking force of solid waste particles
The force required by crushing the solid wastes with different strengths is different, the force required by crushing is classified by dynamic clustering, and the proper crushing force is selected by using the resistance, and the main principle and the implementation are as follows:
1) selection of condensation points
A condensation point refers to a collection of representative points that are considered as a class center to be formed. The choice of the condensation point has a great influence on the classification result. If the choice of the condensation point is different, the final classification result will also be different. A common method for selecting the condensation points on a computer is to calculate the center of gravity of each class, and use these centers of gravity as the condensation points. The invention takes the critical point of the force required by the crushing of common solid wastes as the condensation point.
2) Initial classification
The initial classification method is artificial classification, and common samples (different solid wastes) are subjected to initial classification by experience. After selecting the condensation point (i.e., setting several different crushing forces), each sample was classified by the closest condensation point to it. Each condensation point is classified into one type, the samples are sequentially classified into the type of the condensation point with the closest distance, the gravity center of the type is immediately recalculated to replace the original condensation point, and the classification of the next sample is calculated until all the samples are classified. The method comprises the following steps:
firstly, standardizing the data by using xijRepresents the jth index of the ith sample after normalization,
order to
If all samples are to be classified into K classes, x is assigned to each sampleiComputing
If the integer close to the number is k, the sample x is divided intoiFall into the kth class (K is more than or equal to 1 and less than or equal to K).
3) Classification function
Suppose x1，x2，…，xnRepresents n sample points, initially classified in K classes: g1，G2，…，GkTheir weightsHeart memory
The number of samples in each class is denoted as n1，n2，…，nkBy l (i) denotes xiReference numbers of the classes, definitions xiAnd class GjA distance of Dij，
The classification function can be defined as:
the modification principle according to the batch modification method is to gradually reduce the classification function e until it can no longer be reduced. The classification function as defined herein is a function of,
4) the method comprises the following main calculation steps:
In step 2, a predetermined number of agglutination points are selected for initial classification of the sample. Let xijAnd (4) if the initial classification number is K, calculating according to the formula (1) for the jth index of the ith sample after the standardization treatment, and respectively classifying each sample into the kth class (K is more than or equal to 1 and less than or equal to K), thereby obtaining the initial classification.
And 3, calculating the gravity center of each type, taking the gravity center as a new condensation point, calculating the distance from each sample to the new condensation point, and classifying the distance into the type to which the nearest condensation point belongs. When the calculated center of gravity is identical to the original condensation point, the process is terminated, otherwise the process calculation according to step 3 is repeated. The iterative process of step 3 is an iterative process, each iteration reducing the corresponding classification function. When the centers of gravity of the upper and lower two times are completely the same, the calculation process is converged, and at the moment, the classification function tends to be a fixed value. The final classification result by batch modification is affected by the initial classification, which is a disadvantage of dynamic clustering.
The common solid waste is artificially divided according to the strength grade of the common solid waste, the divided solid waste is crushed by using the crushing plate, the crushing times are determined according to the size of the crushed object, and whether the crushing is carried out is judged according to the size of the crushed solid waste. Whether the size of the solid waste after crushing meets the requirement is judged according to the distance between the crushing plate 3 and the electromagnet plate 2. The distance between the crushing plate 3 and the electromagnet plate 2 is indicated by a display lamp (solid waste crushing, the distance between the crushing plate 3 and the electromagnet plate 2 reaches the circuit connection size, and the display lamp is turned on). The distance determination of the crushing force is carried out by the following processes:
step 1: the method comprises the following steps of (1) manually dividing common solid wastes according to the strength grade of the common solid wastes, and giving the crushing force according to experience;
step 2: observing whether the display lamp is lighted within the time T, and if not, increasing the crushing strength;
and 3, step 3: and (3) re-dividing the crushing force of all samples by utilizing k-means dynamic clustering to obtain the force suitable for common solid waste crushing, carrying out grade classification according to the force, inputting the grade into a control system, and timely adjusting the force according to actual conditions in the solid waste treatment process.
Example 1: waste fluorescent lamp tube for treating solid waste generated by gas
Solid waste gets into the pocket from pan feeding mouth 1, and the pocket is in between electro-magnet 2 and metal breaker 3, and electro-magnet 2 and metal breaker 3 inter attraction under the electromagnetic force effect make metal breaker continuously strike the electro-magnet through current transformation and spring 6, come to carry out the breakage to fluorescent tube in the pocket, and the breaking force size is controlled by the resistor. Before crushing, the air inlet and outlet are closed to prevent waste gas from entering the outside air in the crushing process. During the crushing process, the crushed objects fall into the filter screen 4 through the inlet mesh bag 1, and the crushed objects of the solid waste on the filter screen 4 are continuously crushed by the crushing plate 3 for the second time. In the secondary crushing process, the crushable particles pass through the filter screen 4 to reach the U-shaped plate 9. Before and after the whole crushing, waste gas, large-particle solid waste and small-particle solid waste are mainly treated, and the invention aims at different waste treatment flows as follows:
(1) exhaust gas
After the solid waste is crushed, the waste gas enters the device, and the inlet and the outlet of the device are closed. The exhaust gas is pumped out through the exhaust pipe 19 of the closing cover 18 and stored in the gas storage tank.
(2) Large particle solid waste
Large particle solid waste is generally an uncrushable material such as: metal, plastic film, rubber, etc. The large-particle waste on the filter screen 4 is poured onto the pouring plate 10 by inflating the inflatable column 7. The pouring plate 10 is in a U shape at the front side, the side surface of the pouring plate has a certain slope, and large-particle solid waste reaches the collection basin 12 through the pouring plate 10. The upper part of the collection basin 12 is a collection basin mouth 121, the lower part is a small-hole filter screen 122, the lower part of the collection basin is provided with a copper plate 123 with a ceramic surface layer, an electric heating rod 124 is arranged below the copper plate, and the bottom of the collection basin is made of refractory material 125. Because the action of the electric bar 124, the temperature of the filter screen is higher, plastic substances in large particles are melted at high temperature and reach the copper plate 123 through the filter screen 122, the slope bottom of the copper plate 123 is connected with the plastic output port 11 due to the slope, and the melted plastic substances are discharged from the plastic output port 11. Large particle matter that fails to melt is carried out the magnetic separation by electro-magnet 151, through electro-magnet back and forth swing with iron cobalt nickel matter suction and send iron matter delivery outlet to collect iron matter. The remaining unmelted and magnetically separated material is collected by aerating the collection basin aeration leg 14 to dump the remaining material from the basin into the non-ferrous metal material output 13.
(3) Small particle solid waste
The small particle solid waste is mainly vitreous and friable plastic material. Small particle solid waste passes through filter screen 4 and reaches U template 9, and reach a liquid pipe 17 by U template 9, a liquid pipe 17 top is for advancing (going out) trachea 31, waste gas is taken out in with small particle material through advancing (going out) trachea one, there is communicating pipe 27 on a liquid pipe 17 upper portion, there is the micropore in communicating pipe one bottom, powder material in the small particle reaches a liquid pipe 17 socle through the aperture, great particulate matter reaches second liquid pipe 24 through communicating pipe one, great particulate matter passes through second liquid pipe 24 and collects, generally be the glass material. The small particle substances in the first liquid pipe 17 reach the third liquid pipe 25 through the first water conveying pipe 28, relevant medicaments are added into the third liquid pipe 25 as required to treat the small particles, finally the small particles enter the fourth liquid pipe through the second water conveying pipe 29, and then the water in the pipe is discharged into the water storage part 8 through the second air inlet (outlet) pipe 32, so that the purposes of water recovery and small particle treatment are achieved.
Example 2: coal screening
