Background technology
Roller drier is the cylinder by rotating, and in heat conducting mode, a kind of continuous operation equipment that the moist material dropping in cylindrical shell is dried, is widely used a kind of drying equipment; General roller drying equipment consists of a rotor that is slightly inclination with horizontal line, for example Granted publication number discloses a kind of cross-flow type roller drying machine for the Chinese patent of CN1289742C, this dryer solves the technical barrier of hot-air crossing current by being located at the blowing fan of cylinder ambient air throughput and cylinder outside, it is granular material afterwards that but the method is not suitable for dry, and external fan can only be dredged the hot blast of cylinder outside, and air flow that can not index drum inside.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides a kind of for roller drying machine granular material, that hot-air guidance quality is strong.
In order to solve above technical problem, the utility model provides a kind of roller drying machine, comprise: both ends open and there is the cylinder of cylindrical cavity, be configured for making hot air circulate to pass through the hot air circulate device of cylinder, and the support footing of bottom, support that footing is configured for placing on the ground and for supporting a part of hot air circulate device and cylinder, the stirring piece that also comprises sheet horizontally-arranged, stirring piece is evenly arranged into one along cylindrical helix and stirs the sub-assembly (formation of circular helix: when a moving some A does uniform rectilinear motion along leading round element of a cylinder on the internal chamber wall of cylinder, this bus is done the gyration of isogonism speed around face of cylinder axis again simultaneously, the movement locus of point A is called circular helix), hot air circulate device mainly by outside for delivery of the breather pipe of high temperature circulation gas be inserted in breather pipe air inlet and form for delivery of the playpipe of high-speed gas, this hot air circulate device is by using the high-speed gas of playpipe at negative pressuren zone of breather pipe interruption-forming, the direction that high temperature circulation gas will guide toward playpipe naturally like this flows, this structure had both realized a difficult problem for hot-air guiding, the use amount of also having saved high-temperature gas, without forming Air Flow by strengthening intake simultaneously.
The technical scheme that the utility model further limits is:
Further, breather pipe mainly by receive recyclegas bellmouth entrance section pipe, for the mixing section pipe of mixing two fluids and the outlet section pipe of diffusion speedup, form, the breather pipe of this structure is more obvious by the effect performance of diffusion speedup.
Further, stir in sub-assembly between adjacent two stirring pieces, wherein the floor projection of the floor projection of a slice stirring piece and another sheet stirring piece intersects, this layout designs can realize and on a slice stirring piece above, slide the material coming and can directly drop on another sheet stirring piece, like this can be by the shock of Action of Gravity Field, continual material is become to loose.
Further, the air inlet of breather pipe is provided with air cleaner, and this is clean in order to guarantee to enter the air of cylinder, without granule foreign.
Further, the center of cylinder is provided with rotating shaft and transmission device, described stirring piece be take the floor projection of rotating shaft on cylinder as benchmark inclination 20-30 degree, this angle is deliberated repeatedly final definite through great many of experiments, in this angular range, material can guarantee that again material pace is unaffected when guaranteeing to stop the heat time.
Further, from drum outlet, to its inner stirring piece that extends cylinder overall length 1/3, be equipped with sieve aperture, this special construction is to consider that material, after 2/3 length of having advanced, is substantially dried, in order to make material become finer and smoother, allow material clash into and to sieve under certain rotating speed.
Further, stirring piece is evenly arranged into one along isogonism logarithm helical curve and stirs on the internal chamber wall of cylinder
Mix sub-assembly.
The beneficial effects of the utility model are: the utility model is by the single improvement of putting form, integral layout and part stirring piece structure of stirring piece, both guaranteed the heating, drying time that material is enough, can guarantee the pace of material again, be both fast and sound; By the improvement of hot air circulate device air-supply end structure, the use amount of having saved high-temperature gas when well having solved a hot-air guiding difficult problem, is not only standard but also save.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
The specific embodiment
Embodiment
The roller drying machine that the present embodiment provides, as shown in Figure 1, comprise: rotatingcylindrical drum 1, hot air circulate device, and the support footing 2 of bottom, support that footing 2 is configured for placing on the ground and for supporting a part of hot air circulate device and cylinder 1, the stirring piece 3 of sheet horizontally-arranged is evenly arranged into one along isogonism logarithm helical curve and stirs sub-assembly on the internal chamber wall of cylinder, stir in sub-assembly between adjacent two stirring pieces 3, wherein the floor projection of the floor projection of a slice stirring piece 3 and another sheet stirring piece 3 intersects, the center of cylinder is provided with rotating shaft 4 and transmission device 5, rotating shaft and transmission device coordinate the rolling that realizes cylinder, stirring piece 3 be take the floor projection of rotating shaft 4 on cylinder 1 as benchmark inclination 20-30 degree, from cylinder 1 outlet, to its inner stirring piece 3 that extends cylinder 1 overall length 1/3, be equipped with sieve aperture 6, at the output of the discharging opening middle heat air circulator of cylinder 1, mainly by the breather pipe 7 for delivery of high temperature circulation gas of outside and the playpipe 8 for delivery of high-speed gas that is inserted in breather pipe air inlet, formed, breather pipe 7 mainly by receive recyclegas bellmouth entrance section pipe 7-1, for the mixing section pipe 7-2 of mixing two fluids and the outlet section pipe 7-3 of diffusion speedup, form,
The cylinder that the specification of take is 80*800cm (diameter of cylinder * drum length), the situation of producing vinasse in the situation that rotating speed is 40r/min, the dryer manufacturing parameter that common dryer and the present embodiment provide contrasts as following table:
