Abstract
The invention discloses a rotary drum dryer. The rotary drum dryer comprises a cylinder body (1), a feed hood (2) and a discharge hood (3) which are arranged at the end of the cylinder body (1) and a plurality of shovelling plates (4) which are arranged in the cylinder body (1) along the axial direction of the cylinder wall, wherein each shovelling plate (4) is provided with a groove (41), and the opening of each groove (41) faces to the direction of each shovelling plate. The grooves are arranged on the shovelling plates in the cylinder body, and when the cylinder body rotates, cut tobacco is thrown to a higher position by the shovelling plates and then falls down so that cut tobacco can fully contact with the shovelling plates and the air flow and the drying efficiency of cut tobacco can be increased.
Description
Technical field
The present invention relates to the tobacco shreds drying equipment on the tobacco cutting production line, particularly a kind of roller drier.
Background technology
Shredded tobacco baking is an important generative process in the tobacco business, and machined parameters has crucial influence for aesthetic quality, the chemical composition of product.At present, tobacco business generally adopts the cylinder drying plant that pipe tobacco is dried both at home and abroad, mainly contains two kinds of cylinder tube-sheet type and cylinder thin board types.The baking silk principle of these two kinds of roller driers and technological requirement, design feature are similar substantially, all are to be heat medium with the saturated vapor, for cylindrical shell and hot blast provide heat, by heat transmission and exchange, realize the drying purpose of pipe tobacco.
Generally be provided with flight in the existing roller drier, can turn over pipe tobacco and copy, can increase the touch opportunity of pipe tobacco and air-flow like this, accelerate the process of tobacco shreds drying.But the flight in the existing roller drier is dull and stereotyped, its height with the pipe tobacco upthrow is limited, when certain a slice flight when lower goes to downward-sloping angle, the pipe tobacco on it can very fast landing, this makes pipe tobacco can not reach satisfaction with contacting of air-flow, and heat energy utilization is abundant inadequately.
Summary of the invention
In view of this, the object of the invention is to provide a kind of roller drier, can increase the touch opportunity of pipe tobacco and air-flow, improves the heat energy utilization rate.
For solving above technical problem, technical scheme of the present invention is, a kind of roller drier, the some flights (4) that comprise cylindrical shell (1), are arranged on the charging cover (2) and the discharging cover (3) of described cylindrical shell (1) end and are positioned at described cylindrical shell (1) inside and axially are provided with along barrel, described flight (4) is provided with groove (41), and the opening of described groove (41) is towards the material copy direction.
Described groove (41) is a square groove.Described groove (41) is arranged on the middle part of described flight (4).
Described groove (41) in the degree of depth of material copy direction front end greater than the degree of depth of described groove (41) in material copy direction rear end.
Described flight (4) is divided into two groups, and every group of end near described cylindrical shell (1) is provided with.
Every group of flight (4) is polylith.
Every group of flight (4) circumferentially evenly distributes along the inwall of described cylindrical shell (1).
Described flight (4) is dull and stereotyped.
Described flight (4) is bending, and the bending direction unanimity of each flight (4).
Described flight (4) bending is arc surface.
Compared with prior art, on the flight of the present invention in cylindrical shell groove is set, can increases the touch opportunity of pipe tobacco and air-flow, improve the heat energy utilization rate.Particularly, pipe tobacco throws more by flight that the high position just can drop on the flight in the cylindrical shell rotation process, and air-flow can interweave between flight and shuttles back and forth, and makes pipe tobacco fully contact with flight, air-flow, thereby improves the drying efficiency of pipe tobacco.

The specific embodiment
Basic design of the present invention is on the flight in the cylindrical shell groove to be set, the touch opportunity of increase pipe tobacco and flight and air-flow.
Describe below in conjunction with accompanying drawing and specific embodiment.
Referring to Fig. 1, roller drier comprises cylindrical shell 1, charging cover 2, discharging cover 3 and some flights 4, and wherein: cylindrical shell 1 is connected with hot air duct 5; Charging cover 2, discharging cover 3 are arranged on the end of cylindrical shell 1, and charging cover 2 and discharging cover 3 connect exhausting moisture pipelines 6, and it is connected with humidity discharging system separately respectively, carries out the automatic control and adjustment of humidity discharging; Flight 4 is generally several, and it is inner and axially be provided with along barrel to be positioned at described cylindrical shell 1, thus make pipe tobacco in the rotation process of cylindrical shell 1 by upthrow.
As shown in Figure 2, described flight 4 is provided with groove 41, and this makes that pipe tobacco throws more high position by flight in the cylindrical shell rotation process, thereby improves the touch opportunity of pipe tobacco and flight, air-flow, improves the drying efficiency of pipe tobacco thus.As shown in Figure 3, Figure 4, groove 41 is a square groove, is convenient to machine-shaping.Especially, groove 41 is arranged on the middle part of flight 4, in the degree of depth of material copy direction front end greater than the degree of depth in material copy direction rear end, before the shallow heeling condition in dark back, make material copy more convenient.
As shown in Figure 1, flight 4 is divided into two groups, and every group of end near described cylindrical shell 1 is provided with; Every group of flight 4 can be three or other quantity, and its inwall that is evenly arranged in cylindrical shell 1 is circumferential, can make material copy even.
In the present embodiment, flight 4 is dull and stereotyped, and its middle part is provided with groove 41, makes pipe tobacco be thrown height and puts the higher place of cylindrical shell 1.In addition, flight 4 is bends to arc surface, and the bending direction unanimity of each flight 4, this helps further pipe tobacco to be thrown high, to increase pipe tobacco and air-flow touch opportunity.
On the flight 4 of the foregoing description in cylindrical shell 1 groove 41 is set, it is advantageous that: in cylindrical shell 1 rotation process, pipe tobacco just can drop on the flight 4 by the more high position that flight 4 throws in the cylindrical shell 1; At this moment, air-flow can interweave between flight 4 and shuttle back and forth, and makes pipe tobacco fully contact with flight 4 and air-flow, helps improving the heat energy utilization rate, improves the drying efficiency of pipe tobacco.
Be pointed out that the front is that example describes the present invention with the pipe tobacco, but this is not limited in pipe tobacco extremely, needs dried material can be suitable for equally for other.
Only be preferred implementation of the present invention below, should be pointed out that above-mentioned preferred implementation should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with claim institute restricted portion.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
