Below in conjunction with accompanying drawing the present invention is described in further detail.
Fig. 1 is a municipal refuse recycling treatment process flow chart.
Fig. 2 is a municipal refuse processing equipment for recycling principle assumption diagram.
Fig. 1 municipal refuse recycling treatment comprises following technical process:
Soot rubbish [1] is behind primary breakup [2], the deodorizing [3] that carries out disinfection is handled, sub-elect ferromagnetic material in the rubbish by metal sorting [4], for the ease of rubbish being done further break process, rubbish behind the primary breakup is separated into hard material material flow of being made up of masonry, pottery, glass etc. [6] and the pliable and tough material material flow of being made up of plastics, paper etc. [7] by sorting [5], and hard material and pliable and tough material carry out break process by hard material fragmentation [8] and pliable and tough material fragmentation [9] respectively.
Fritter rubbish after broken mixes with adhesive [10], admixture [11] in proportion, finishes batching [12]; Adhesive uses the oxygen magnesium cement gel ramming material that organic matter and inorganic matter is all had adhesive effect, and it is made up of magnesia and magnesium chloride solution; The effect of admixture is to improve the performance of the construction material that generates, can be various rubbles, it also can be broken building waste fragment afterwards etc., in batching during to the metering of various components in certain proportion, can be artificial mode, also can adopt the electronics automatic batching system of microcomputerized control to finish.
Material after batching is finished drops into mixing plant [13] and stirs, and obtains the mixed slurry of density field, concentration field, temperature field uniformity; Above-mentioned slurry by the size of mold volumes, is supplied with a certain amount of slurry by injection molding machine [14] at every turn, is injected in the mould; Mould is vibrated it by vibration conveying equipment [15] together with the slurry in the mould, guarantees that slurry is more closely knit in the mould; By certain hour curing molding [16], carry out the demoulding [17] operation by slurry in the mould after the vibration again, obtain different construction material [18].
Mould can be positioned in the environment of normal temperature, normal pressure in the curing molding together with slurry, in order to shorten the slurry curing time, can in the space of airtight insulation, place mould and the slurry that needs curing molding, and to heating in the airtight keeping warmth space, to improve the temperature in the local space.
In Fig. 2 municipal refuse processing equipment for recycling, the fragmentation of rubbish is finished by twice fragmentation, i.e. primary breakup and secondary breakup.Can use discaling roll type disintegrating machine [2] in the primary breakup, this disintegrating machine is fritter rubbish with the bulk refuse breaking, and tears and open bagged garbage by effects such as extruding and cuttings.In the secondary breakup of rubbish, the fragmentation of hard material is selected for use hammer mill [8], can select rotation cutting type breaking machine [9] for use pliable and tough material; Hammer mill is made up of central rotor and a plurality of radially tup, by effects such as impact, collision, extruding, rubbish is done further fragmentation; Rotation cutting type breaking machine is fixed with cutting blade on its rotor rotated, by the rotation cutting and crushing material of cutting blade on driven by motor rotor and the rotor.Plastic breaker on the market just can be used for this respect.
