Abstract
The invention provides a three-pass rotary drum and belongs to the field of rotary drum heating. The invention is implemented by a technical scheme that: the three-pass rotary drum comprises an outer drum, a middle drum and an inner drum, wherein the middle drum is formed by connecting a plurality of short conical drums one to end with the same cone vertex diameter; and adjacent short conical drums are connected by annular connecting plates end to end. The invention provides the technical scheme of smartly designing the structure of the middle drum, forming the middle drum by using the plurality of short conical drums and processing and manufacturing the equipment to make a large-tonnage three-pass rotary drum of a required length or processing capacity according to requirements; the structure of the three-pass rotary drum is simple; the installation and use are convenient; and more importantly, the large-size equipment can be realized according to requirements and the structure is compact.
Description
Technical field
The present invention relates to a kind of three-pass rotary drum drying unit, relate in particular to a kind of three-pass rotary drum.
Background technology
With the immediate prior art of the present invention be that publication number is CN201141727; The patent No. is: 200720157497.3 patent of invention; It discloses a kind of three-pass rotary drum; Be made up of three conically shaped group covers, the reverse suit of the big to each other osculum of each conically shaped has formed material from the outer inwardly cavity of three backhauls of motion.Be taper owing to each is simplified, and certain tapering must be arranged, could guarantee the smooth motion of material; When equipment capacity increased, the diameter difference at conical shell two ends increased, and had brought difficulty for transportation and assembling manufacturing; Therefore, this structure can not be applied to large-scale drying plant.
Summary of the invention
The present invention be directed to the existing in prior technology shortcoming; The structure of tube in having proposed to design dexterously; Middle tube is made up of a plurality of short taper profile cylindrical shells, can as required apparatus processing be manufactured the technical scheme that needs the large-tonnage of length or working ability three-pass rotary drum, it is simple in structure, easy to install; Importantly can realize according to actual needs maximizing, and compact conformation.
The present invention realizes through following technical measures: a kind of three-pass rotary drum; Comprise urceolus, middle tube and inner core; Tube is connected and composed by the short taper profile cylindrical shell that several vertex of a cone equal diameters, cone bottom diameter equate from beginning to end in said, connects through annular connecting plate between the head and the tail of adjacent said short taper profile cylindrical shell.
Of the present inventionly advance one and improve and also have, above-mentioned inner core is that cylinder is simplified, screw feeder is installed in the cylinder in said; Urceolus is a cylindrical tube.
Concrete characteristics of the present invention also have, and are provided with inner reinforced plate longitudinally between above-mentioned middle tube and the inner core, and the cavity between middle tube and the inner core is divided into several independently little cavitys.Be provided with outer longitudinally gusset between middle tube and the urceolus, the cavity between middle tube and the urceolus is divided into several independently little cavitys.
The beneficial effect of this programme can be learnt according to the narration to such scheme; Owing to adopted middle tube to connect and compose from beginning to end by several short taper profile cylindrical shells; The diameter difference distance that connects the head and the tail two ends that can significantly reduce existing integral conical body between the simplified head and the tail of said adjacent short taper profile through annular connecting plate; Therefore, can make large tonnage the baking in equipment.Inner core among the present invention and/or urceolus are cylindrical tube, can guarantee that material forms axial flow along the inside and outside wall of middle tube, can realize the maximization of drying roller again easily.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
Fig. 2 is the B-B cutaway view of Fig. 1.
Among the figure, 1. inner core, 2. in tube, 3. urceolus, 4. screw feeder, 5. annular connecting plate, 6. inner reinforced plate, 7. outer gusset.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, through a specific embodiment, this programme is set forth below.
As shown in Figure 1; The present invention is a kind of three-pass rotary drum; Comprise urceolus 3, middle tube 2 and inner core 1, said middle tube 2 is connected and composed by the short taper profile cylindrical shell that several vertex of a cone equal diameters, cone bottom diameter equate from beginning to end, connects through annular connecting plate 5 between the head and the tail of adjacent said short taper profile cylindrical shell.The present invention can all be set to cylindrical tube with inner core 1 and urceolus 3, at this moment, can equipment accomplished to maximize, and can guarantee that material flows smoothly in each cavity.Inner core 1 is cylinder when simplified, and the inner core domestic demand is equipped with screw feeder 4.As shown in Figure 2, be provided with inner reinforced plate 6 longitudinally between middle tube 3 and the inner core 1, the cavity between middle tube 2 and the inner core 1 is divided into several independently little cavitys; Be provided with outer longitudinally gusset 7 between middle tube 2 and the urceolus 3, the cavity between middle tube 2 and the urceolus 3 is divided into several independently little cavitys.It is divided into the thermally equivalent effect that a plurality of independently loculus bodies can improve material.
The present invention can pass through existing techniques in realizing without the technical characterictic of describing, and repeats no more at this.Certainly; Above-mentioned explanation is not to be limitation of the present invention; The present invention also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also should belong to protection scope of the present invention.
Claims (5)
