Abstract
The invention provides a material raising device of a dryer, which comprises a barrel and material raising plates of the dryer. The material raising device is characterized in that both end surfaces of the barrel are provided with one to three supporting bars, both ends of a plurality of cross-shaped material raising plates are respectively fixed with the supporting bars on the both end surfaces of the barrel, the material raising plates are evenly arranged on the end surfaces of the barrel. The four ends of each cross-shaped material raising plate are folded and pressed at a bevel of 105-125 degrees, the section is regularly spiral. Thus, the height for hoisting the materials and the area for scattering the materials are increased. As the material rising device adopts the material raising plates with the spiral sections to lead the material to wavily wiggle ahead along the axial direction of the barrel, the device has certain functions of guidance, flow equalization and material resistance, improves the scattering evenness of materials, increases the detention time of the materials in the barrel as well as the times for turnover drying, avoids the phenomena of wind tunnel and step material scattering, greatly improves the drying efficiency of the dryer, saves energy and has the advantages of simple structure and easy manufacture.
Description
Affiliated technical field
The present invention relates to a kind of raising material unit of dryer.
Background technology
Rotating drum type drying machine is the capital equipment that manufacturing enterprises such as present building materials, metallurgy dry material, its operation principle is by being arranged at the lifting blade of drier body inwall, material taken to certain height in the drier body rotation process inclines and spreads down from cylindrical shell bottom, material is contacted with hot gas, thereby reach the purpose of dry materials.Existing lifting blade is the strip flat board that certain thickness steel plate crimping forms, though simple in structure, be easy to make, but the hoisting depth to material is limited, and the projected object material level is put concentrated, and the contact area of material and hot gas is less, easily form wind-tunnel on the cross section of cylindrical shell, drying efficiency is lower; Especially the material when larger particles enters in the cylindrical shell, and its surperficial moisture content evaporates rapidly, forms the dried shell of one deck, hinder granule interior moisture content and separate out, thereby drying effect is reduced greatly, and energy consumption is big.
Summary of the invention
For overcoming the deficiencies in the prior art part, the invention provides a kind of rational in infrastructure, effectively improve drying effect and efficient, the raising material unit of the oven dry that cuts down the consumption of energy.
The technical scheme that the present invention solves its technical problem employing is, the cylindrical shell and the lifting blade that comprise dryer, it is its feature: one to three support bar is housed on the both ends of the surface of cylindrical shell, the two ends that several piece is criss-cross lifting blade respectively with the cylindrical shell both ends of the surface on support bar fix, lifting blade evenly distributes on the end face of cylindrical shell.
Four terminal crimpings of above-mentioned cross lifting blade become 105～125 knuckle, and its cross section is right-handed screw shape, thereby improve the hoisting depth of material and shed area.
Beneficial effect of the present invention is: owing to adopt the cross section to be the lifting blade of right-handed screw shape, material is wriggled forward to being wavy along drum shaft, has certain guiding, current-sharing and resistance material function, make the evaporation and crusting rapidly of its surperficial moisture content even if the higher material of water content is also unlikely, improved the uniformity of shedding of material simultaneously, increased the number of times of the holdup time of material in cylindrical shell and upset oven dry, and the several piece lifting blade complements one another in the position in cylindrical shell, wind-tunnel and stage spreading phenomenon have been avoided, make material in cylindrical shell, be waterfall shape, increased substantially the drying efficiency of dryer, saved the energy, and simple in structure, be easy to make.
Description of drawings
Fig. 1 is the structural representation of embodiment of the invention I;
Fig. 2 is the structural representation of embodiment of the invention II.
Among the figure: 1 is that cylindrical shell, 2 is that lifting blade, 3 is support bar.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Example I: the cylindrical shell 1, support bar 3 and the lifting blade 2 that the present invention includes dryer; In symmetry on the both ends of the surface of cylindrical shell 1, equably be equipped with two ends that 3, seven of three support bars are criss-cross lifting blade 2 respectively with cylindrical shell 1 both ends of the surface on support bar 3 fix.A lifting blade 2 wherein is positioned at cylindrical shell 1 end face center, and in addition the center of six lifting blades 2 is with cylindrical shell 1 concentric circles and evenly distributes.Four terminal crimpings of every ten shape lifting blade 2 become knuckle α=115 °, make its cross section be right-handed screw shape.
Example II: the cylindrical shell 1, support bar 3 and the lifting blade 2 that the present invention includes dryer; On the both ends of the surface of cylindrical shell 1 symmetry, equably be equipped with 3, five of three support bars be ten shapes lifting blade 2 two ends respectively with cylindrical shell 1 both ends of the surface on support bar 3 fix.A lifting blade 1 wherein is positioned at the body end surface center, and in addition the center of four lifting blades 2 is with cylindrical shell 1 concentric circles and evenly distributes.Four terminal crimpings of every ten shape lifting blade 2 become knuckle α=120 °, make its cross section be right-handed screw shape.
