Abstract
The utility model discloses a kind of drying drum, belong to drying device field, a kind of drying drum improving product drying quality is provided, comprises roll body, the outer circumference surface of roll body is wound around and is provided with heat exchanger tube; Described heat exchanger tube and roll body matched in clearance.By passing into the heat exchange sources such as hot blast gas or steam in heat exchanger tube, realize the heating to roll body by heat exchanger tube, then realize the drying to material by roll body; The heat exchange sources such as hot blast gas or steam that effectively prevent contact with direct between dry products; Reduce product may with the chemical reaction in the heat exchange source such as hot blast gas or steam, improve the dried quality of final products.
Description
Technical field
The utility model relates to drying device field, particularly relates to a kind of drying drum.
Background technology
At present, conventional drying drum enters the heat exchange sources such as hot blast gas or steam from one end of cylinder, and discharge from the other end; It is by cylinder, the material direct contact heat transfer of hot blast gas or steam and needs drying, adopt this drying drum when material drying, because material directly contacts with hot blast gas or steam, therefore and hot blast gas or steam etc. easy for some produce for the material of chemical reaction, will affect final dried product quality.
Utility model content
The technical problem that the utility model solves is to provide a kind of drying drum improving product drying quality.
The utility model solves the technical scheme that its technical problem adopts: drying drum, comprises roll body, the outer circumference surface of roll body is wound around and is provided with heat exchanger tube; Described heat exchanger tube and roll body matched in clearance.
Further: on heat exchanger tube, be also provided with one layer of heat preservation material; Insulation material and roll body matched in clearance.
Further: be provided with one deck iron sheet material in the periphery of insulation material.
Further: the top of the feeding mouth side of roll body is provided with discharge duct; Described discharge duct is communicated with the internal cavity of roll body.
The beneficial effects of the utility model are: the heat exchange sources such as hot blast gas or steam that avoid contact with direct between dry products; Reduce product may with the chemical reaction in the heat exchange source such as hot blast gas or steam, improve the dried quality of final products.
Accompanying drawing explanation
Fig. 1 is the structural representation of drying drum described in the utility model;
Fig. 2 is the enlarged diagram of regional area A in Fig. 1;
Be labeled as in figure: roll body 1, feeding mouth 11, outer circumference surface 2, heat exchanger tube 3, the heat exchanger tube port of export 31, heat exchange tube inlet end 32, insulation material 4, iron sheet material 5, discharge duct 6, feed hopper 7, tugboat structure 8, driving mechanism 9, gear ring 91.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figures 1 and 2, drying drum described in the utility model, comprises roll body 1, the outer circumference surface 2 of roll body 1 is wound around and is provided with heat exchanger tube 3; Described heat exchanger tube 3 and roll body 1 matched in clearance.
Wherein, as shown in FIG., roll body 1 is generally supported by tugboat structure 8, drives roll body 1 unitary rotation by driving mechanism 9 and its with engaging of gear ring 91 simultaneously.Material is entered by feed hopper 7 feeding mouth 11 one end from roll body 1, simultaneously along with the rotation of roll body 1 and some scraper structures of being arranged on roll body 1 inside make material move down gradually.
In the utility model, the driving principle of roll body 1 and supporting construction etc. can be same as the prior art, as mentioned above.
Core of the present utility model changes the heat transfer relation between material and heat exchange source; Rely on and be provided with in heat exchanger tube 3 pass into heat source substance to being arranged on roll body 1 outer circumference surface 2 is wound around, heated by the wall of heat exchanger tube 3 pairs of roll body 1, be positioned at the material of roll body 1 like this, realize conducting heat by contacting with the wall of roll body 1, and then reach the effect of dried material.Wherein, the heat source substance passed in heat exchanger tube 3 can be the liquid substance etc. of hot-air, vapours or heat in theory.
Consider that roll body 1 operationally needs continuous rolling, and therefore heat exchanger tube 3 itself along with rolling, can not require that heat exchanger tube 3 is wrapped in after on roll body 1 and its matched in clearance; Both when real work, heat exchanger tube 3 had not rotated with roll body 1, also must not hinder the rotation of roll body 1 simultaneously.Meanwhile, need when heat exchanger tube 3 runs in tugboat structure 8 structures such as being arranged on sealed supporting ring structure on roll body 1 or gear ring 9 to stride across, guaranteed normal work.Certainly, heat exchanger tube 3 can also comprise multistage pipeline independent of one another; Every segment pipe all has the corresponding heat exchanger tube port of export 31 and heat exchange tube inlet end 32.
In addition, in order to improve heat exchanger tube 3 and roll body 1 wall between heat transfer, reduce the heat waste loss of heat exchanger tube 3 simultaneously, can also be provided with one layer of heat preservation material 4 on heat exchanger tube 3.Insulation material 4 is also general not along with roll body 1 rolls, and therefore requires insulation material 4 and roll body 1 matched in clearance.
In addition, also one deck iron sheet material 5 can be set again in the periphery of insulation material 4; Further raising heat insulation effect, reduces the heat waste of heat exchanger tube 3.
In addition, because the utility model is without the need to passing into the heat exchange sources such as hot blast gas or steam in the inside of roll body 1, in theory, only need to arrange on roll body 1 accordingly for supplying feeding mouth and the discharging opening of material turnover; But, consider that material has steam or gas and produces after roll body 1 inner drying, for the ease of the discharge of this part steam or gas, the top of feeding mouth 11 side of roll body 1 can be provided with discharge duct 6; Described discharge duct 6 is communicated with the internal cavity of roll body 1.Why discharge duct 6 being arranged on the top of feeding mouth 11 side, is because this position is generally the highest place of roll body 1 internal cavity, is conducive to the discharge of steam or the gas produced in roll body 1 inside.
Certainly, discharge duct 6 can not rotate along with roll body 1.More general way is respectively arranged with at the two ends of roll body 1 not along with the protective cover structure that roll body 1 rotates, and like this, discharge duct 6 can be arranged on the protective cover of corresponding feeding mouth 11 side.
