Specific embodiment
The above objects, features, and advantages of the utility model in order to facilitate understanding, are illustrated below with reference to embodiment.It answers
Understand, these embodiments are merely to illustrate the utility model rather than limitation the scope of the utility model.For these implementations
A variety of modifications of example will be apparent to those skilled in the art, the general principles defined herein,
It can be achieved in other embodiments without departing from the spirit or scope of the present utility model.
The utility model proposes three backhaul drying rollers, overall structure is roughly the same with the prior art, comprising: from interior and
The feed inlet 1 and combustion chamber 3 of roller one end is arranged in inner cylinder 5, middle cylinder 6 and the outer cylinder 7 being successively arranged outside, is arranged in roller
The discharge port 2 and cyclone dust collector 4 of the other end.The combustion chamber 3 is connect with blower, for blowing high-temperature gas from left to right
Enter inner cylinder 5, then, space of the high-temperature gas right-to-left between inner cylinder 5 and middle cylinder 6 is turned back, later, gas from left to right from
Space between middle cylinder 6 and outer cylinder 7 is blown to cyclone dust collector 4.The hot-gas temperature that combustion chamber 3 is blown out is up to 700 DEG C of left sides
The right side, as detour is turned back continuous cooling, the gas temperature at cyclone dust collector 4 is down to 60 DEG C or so, can be using commonly setting
It is standby to be handled.Material with high-temperature gas movement, from feed inlet 1 to the right, moved right again to discharge port 2 and obtained to the left
Sufficiently drying.
The shovelling plate 8 of helically pusher arrangement, the shovelling plate 8 are respectively set on the inner wall of inner cylinder 5, middle cylinder 6 and outer cylinder 7
Structure it is as shown in Figure 2 and Figure 3.The shovelling plate 8 includes two parts: a part is spiral plate 81 similarly to the prior art, another portion
Dividing is that arranged for interval raises sand plate 82 on the spiral plate 81, and sand plate 82, spiral plate 81 and the inner wall raised surrounds
The space with opening is formed, the space with opening can accommodate material, and material can be passed in and out from the opening.
With continued reference to Fig. 2, Fig. 3, the circumferential direction being open towards roller, therefore when raising sand plate 82 and turning to low level, material from
Opening enters space；When raising sand plate 82 and turning to a high position, material is flowed out from opening again.The sand plate 82 of raising includes three sides
Wall, one is the main wall a positioned opposite with the inner wall, and one is the first connection wall for connecting main wall a and the inner wall
B, the other is the second connection wall c of connection main wall a and spiral plate 81.Referring to fig. 4, the sand plate 82 of raising is by one piece of metal plate
Part bending forms, and left circles arc side is used for and welds at the top of spiral plate 81, and right circles arc side is used to weld with the inner wall, bottom
Short side is used to weld with 81 side of spiral plate, therefore the bottom in the space is not planar, but linear, advantageously reduces technique stream
The complexity of journey especially reduces welding.
Referring to Fig. 3, the main wall a is not parallel with circumferencial direction, but along from the bottom in the space to opening
Direction, the main wall a is tilted towards drums inside namely the space openings are big, bottom is sharp, is so ensuring Welder
Under the premise of skill is simple, weld seam is short, the volume in space is bigger.Moreover, because main wall a is to be in tilted layout, with circumferencial direction
With inclination angle, when this raises sand plate 82 and moves to higher position, apart from top there are also when the size of inclination angle, material overcomes friction
Power starts to pour out out of space, formation material curtain.Later, with continuing to rotate for sand plate 82 is raised, material is constantly poured out, and is formed
One large-scale material curtain, is conducive to material and is adequately dried.Preferably, the range that the inclination angle is 15 °~25 °
Within, the width of material curtain is widened as much as possible, increases drying effect.Correspondingly, the second connection wall c triangular shape,
The trapezoidal shape of the first connection wall b.The quantity setting for raising sand plate 82 needs the property in view of cost and material, such as
Being easy for fruit material is agglomerating, viscosity is larger, can be set it is more intensive raise sand plate 82, otherwise can be a small number of, with a circle range
Interior setting 2~6 is preferably.
