Abstract

The utility model discloses a three-layer rotary drum drier, comprising a frame and a rotary drum, wherein the frame is provided with a supporting wheel and a power mechanism; the rotary drum consists of a drum body, a feeding end head and a discharging end head; the outer round surface of the drum body is provided with a ring-shaped running belt and a gear ring; the running belt and the supporting wheel are matched; the gear ring and the power mechanism are connected; the drum body is three-layered and is formed by an inner drum body, a middle drum body and an outer drum body which are fixedly sleeved; a gap is arranged between adjacent drum bodies; the inner round surfaces of the drum bodies are respectively provided with a shovelling plate, and the inclined directions of the shovelling plates on the adjacent drum bodies are reverse so as to form an S-type channel and lead the material to adopt a mode of combining down flow and reverse flow in a three-layered rotary drum to be dried. The three-layer rotary drum drier adopts a three-layered drum sleeving form, is an S-type channel, and has unique design, reasonable structure, high drying efficiency, good drying effect, and good economic benefit after being promoted.

Description

Three layers of rotary roller dryer

One. technical field:

The utility model relates to a kind of drying machine, particularly relates to a kind of three layers of rotary roller dryer.

Two. background technology:

At present, a variety of drying plants such as rotary roller dryer, pulsed pneumatic drying machine, boiled bed drying machine, Pipebundledrier, Rotatingandflashstreamingdrier are arranged in the drying plant industry at home, its form and structure are also different, the industry of using is also different, and wherein, rotary roller dryer adopts the oven dry of individual layer cylinder mostly, following current or adverse current, the time that material stops in cylinder is shorter, and is dry insufficient, increased the post-production cost.

Three. the content of utility model:

Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of uniqueness, rational in infrastructure, drying efficiency is high and drying effect is good three layers of rotary roller dryer of designing are provided.

The technical solution of the utility model:

A kind of three layers of rotary roller dryer, contain organic frame and cylinder, be equipped with on the described frame and support support roller and actuating unit, described cylinder is by cylindrical shell, charging termination and discharging termination are formed, described cylindrical shell outer round surface is provided with annular and runs band and gear ring, described race band matches with described support support roller, described gear ring is connected with described actuating unit, described cylindrical shell is three layers, by internal layer cylinder, middle level cylindrical shell and outer layer barrel suit fixedly form, be provided with the gap between the adjacent cylindrical shell, be provided with flight on the internal circular surfaces of all cylindrical shells, and the incline direction of the flight on the adjacent cylindrical shell is opposite, forms S type passage, and the mode that makes material adopt following current and adverse current to combine in three layers of revolving cylinder is dried material.

Described actuating unit is made of reductor and buncher, and described reductor is connected with a gear shaft with sprocket wheel by chain, and the travelling gear on the described gear shaft is connected with described gear ring.

Described actuating unit is made of reductor and buncher, and described reductor is connected with a gear shaft by shaft coupling, and the travelling gear on the described gear shaft is connected with described gear ring.

The beneficial effects of the utility model:

1, the utility model adopts the form of three layers of cylinder suit, S-type passage, material is that following current and adverse current combine with the contact form of hot-air, has prolonged the time of staying of material in cylinder, increased the heat exchange area of material in cylinder, prolonged the heat exchanger time of material in cylinder, fully dry, satisfactory for result, in addition, also shorten the length of cylinder, reduce floor space, enhance productivity.

2, be provided with the inclination flight on the inwall of three layers of cylinder of the utility model, this flight can make material along S type channel flow, can make material translate into top by the bottom again, is convenient to material and contacts with hot-air, improves drying effect.

3, it is little to the utlity model has floor space, and output is big, and material is heated evenly, and advantages such as less investment are easy to promote, and have good economic benefits.

Four. description of drawings:

Fig. 1 is the structural representation of three layers of rotary roller dryer;

Fig. 2 is the vertical view of three layers of rotary roller dryer shown in Figure 1;

Fig. 3 is the structural representation of three layers of revolving cylinder among Fig. 1.

Five. the specific embodiment:

Embodiment: referring to Fig. 1-Fig. 3, among the figure, the 1-cylindrical shell, 2-runs band, the 3-gear ring, 4-charging termination, 5-discharging termination, 6-supports support roller, 7-travelling gear, 8-frame, 9-reductor, 10-buncher.

The type of attachment of three layers of roller drier: at first internal layer C, middle level B, three barrel jackets of outer A are fitted together and form whole cylindrical shell 1, then suit runs and is with 2 and gear ring 3 and fix welding; Be welded on above the frame 8 supporting support roller 6, welding finishes just can be lifted on cylindrical shell 1 and supports on the support roller 6, makes it stability of rotation again; Then charging termination 4 and discharging termination 5 are packaged on cylindrical shell 1, and be fixed on above the frame 8, do not hit the front and back end head when cylindrical shell 1 is rotated with gripper shoe; Be welded on above the frame 8 after at last travelling gear 7 and gear ring 3 engagements being mixed up, the gear shaft of travelling gear 7 is connected with reductor 9 with chain by sprocket wheel, and reductor 9 adopts shaft coupling to connect connection with buncher 10.Also can take reductor 9 to pass through the direct and gear shaft ways of connecting of shaft coupling, with simplified structure.

Operation principle: at first moved to discharging termination 5 by charging termination 4 from internal layer cylinder when material enters, this moment, material was consistent with the traffic direction of hot-air, was called the following current form; When material moves to the end face of internal layer cylinder, be slipped to automatically in the cylinder of middle level, material is moved to charging termination 4 by discharging termination 5 under the effect of middle level cylinder flight 11, and this moment, material was opposite with the direction of hot-air, was called the adverse current form; When material moves to the middle level body end surface, be slipped in the outer layer barrel automatically, same under the effect of outer layer barrel flight 11, material moves to discharging termination 5 uniformly, this moment, material also was consistent with the traffic direction of hot-air, be called the following current form, last material 5 carries out discharging from the discharging termination.

The specific constructive form that changes the fixed form of three layers of cylindrical shell, the specific constructive form that changes flight and change actuating unit can be formed a plurality of embodiment, is common excursion of the present utility model, does not describe in detail one by one at this.
