Specifically, after material is dried in body of heater 1, through the second air inlet 91, the gas in body of heater 1 and after material-heat-exchanging is introduced in cyclone cylinder; Under the effect of blower fan, gas spin in cyclone cylinder rise motion, in uphill process, the solid particle contained in gas and liquid are got rid of on the internal face of cyclone cylinder, under the effect of self gravitation, solid particle and liquid deposition are in the bottom of cyclone cylinder; And get rid of solid particle, liquid a part of gas through the second gas outlet directly discharged to outside air, another part gas is then transported in the cavity to wind apparatus 4 through the 3rd gas outlet 92, mix with to the hot gas in wind apparatus 4 cavity, portion gas after dedusting is recycled, reduces the heat required for heating hot gas.
In addition, in gas after dedusting, moisture content is typically in 20%-30%, and it is almost 0% to the moisture content of hot gas in wind apparatus 4, the dedusting gas that moisture content is 20%-30% is introduced in wind apparatus 4, mix with dry hot gas, to form the hot gas that moisture content is 6%-15%, this hot gas is introduced in body of heater 1 with the efficiency of material-heat-exchanging and effect, than the dry hot gas that moisture content is 0% introduced in body of heater 1 with the efficiency of material-heat-exchanging and better effects if. Because, containing a small amount of moisture in hot gas, under equivalent environment, specific heat of water holds the specific heat capacity more than air, and during dry same amount of material, the heat required for water is less, thus reducing the heat that dried material needs, improving drying efficiency, but the moisture content in hot gas is unsuitable too high, too high rear heat exchange efficiency can decline on the contrary, then, the optimum moisture content of hot gas controls at 6%-15%.
For the charging gear 2 in above-mentioned embodiment, material-receiving device 3. Wherein, charging gear 2 is preferably batcher of the prior art, for instance elevator, and is arranged on the hopper on charging aperture 11, and the feed opening of elevator faces toward or extend in hopper can. Material-receiving device 3 is preferably conveying worm, or belt conveyor and chain transfer, or is directly arranged below a discharging bin at discharging opening 12.
As the charging aperture 11 offered on body of heater 1, discharging opening the 12, first air inlet 13 and the first gas outlet 14 preferred embodiment, as shown in Figures 2 and 3, charging aperture 11 is opened on body of heater 1 sidewall radially, discharging opening 12 be opened in body of heater 1 in Z-direction bottom outer wall on, first air inlet 13 is opened in the top exterior walls in Z-direction of the body of heater 1 near charging aperture 11 place, first gas outlet 14 is opened in the body of heater 11 top exterior walls in Z-direction, and relative with the position of discharging opening 12.
In a word, the material handling system of the present embodiment, when to dry materials, first the performance according to material, the parameters such as such as moisture content, size, degree of drying, adjust the spacing between blade 7 and body of heater 1 inwall, the angle that blade 7 is arranged, and spacing between adjacent two peripheries in the second rotating shaft 5 in shaft 6 surface thereof; And the amount according to the hot gas added in the amount of material, introducing body of heater 1, calculate material in body of heater 1, stop the degree of drying that how long just can reach necessary requirement, and test repeatedly can be passed through, draw the optimized parameter that each material is dried, thus preparing the drying oven of relevant parameter and there is the material handling system of this drying oven.
Certainly, as deformation, it is also possible to omit the first air inlet 13, and only by puff prot air inlet.
Embodiment 2
The present embodiment provides a kind of material processing method, comprises the steps
The step that material is heated;
The step that material is stirred;
The step that material is dried;
The step of described heating, the step of stirring and dry step adopt same system to carry out simultaneously, and described system is the material handling system recorded in embodiment 1.
Owing to adopting the material handling system recorded in embodiment 1, therefore, this material processing method has any one advantage described above.
This material processing method is particularly suited for the process of mud class material, it is possible to by good stirring action, mode material dry in be mutually bonded, improve the final drying effect of material.
As preferred embodiment, the bore of described puff prot is not more than 3mm, the jet velocity at described puff prot place is more than the rotary speed of described second rotating shaft, so that described puff prot place quickly sprays air-flow, material between adjacent shaft 6 is stirred rapidly, it is prevented that material is bonded on rotating shaft and shaft in motor process.
Obviously, above-described embodiment is only for clearly demonstrating example, and is not the restriction to embodiment. For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description. Here without also cannot all of embodiment be given exhaustive. And the apparent change thus extended out or variation are still among the protection domain of the invention.
