Abstract
The utility model discloses a dual-spiral steam drier. A main body of the dual-spiral steam drier is a drying barrel. The drying barrel is of a horizontal groove-column structure of which the section is of a semi-circular shape. The groove-column structure is hollow, and the arc surface faces upside. The upper part of the groove-column structure is provided with a radiating conical cover. Two U-shaped drying grooves which are connected with each other are installed in the hollow part of the groove-column structure, and the two U-shaped drying grooves are connected on the medial axis of the drying barrel; at the same time, spiral stirring shafts are installed in the two U-shaped drying grooves, and the two spiral stirring shafts are symmetrically installed; and linkage gears are arranged between the two spiral stirring shafts. The dual-spiral steam drier has a reasonable structure, can uniformly and fully exchange the heat, can continuously dry the material, and has the advantages of energy saving and high efficiency.
Description
Technical field
The utility model relates to drier unit, is specially a kind of double helix steam dryer that can be used for chemical industry powder material drying.
Background technology
In general chemical industry; often can use powder material; such as various ore powders, wood powder etc.; in the preliminary working process to these powder materials; often can carry out drying to powder material, the degree of drying of powder material directly has influence on the quality of final finished, particularly in some dangerous chemical industries; in engineering powder type explosive manufacture process, require quite harsh to the degree of drying of the wood powder of one of raw material.And commonly used drying equipment on the market, conducts heat inhomogeneous, drying efficiency is low, require to control material each drying time of harshness to drying condition and need to repeatedly repeat drying, serious waste of resources; Simultaneously, the degree of uncontrollable dry materials can only draw general conclusion by rule of thumb, supports limited to field of fine chemical.
The utility model content
The technical problem that the utility model solves is to provide a kind of double helix steam dryer, its energy-saving effect is obvious, heat exchange fully and evenly, and thermal medium with add that thermal material is non-directly to be contacted, ectocrine material physicochemical property not can be in order to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
The double helix steam dryer, its main body is dry cylindrical shell, described dry cylindrical shell be an accumbency and tangent plane be semicircular groove rod structure, hollow and the cambered surface of whole groove rod structure up, its top is provided with heat radiation cone cover, and two continuous U-shaped dry slots are installed in the hollow parts of groove rod structure, described two U-shaped dry slots link to each other in the position, axis of dry cylindrical shell, simultaneously, the spiral shaft all is installed in the groove of two U-shaped dry slots, two symmetrical installations of spiral shaft, and between two spiral shafts, be provided with linkage gear.
In the utility model, the direction of rotation of described two spiral shafts is opposing, and with rising with stopping, designs a volume backpitch blade in the termination of every spiral shaft flow direction of material, with circulation in guaranteeing to form in two U-shaped dry slots.
In the utility model, be provided with some shaft orientation reinforcing ribs on the lateral surface of described U-shaped dry slot, in order to guarantee the intensity of U-shaped dry slot.
In the utility model, described groove rod structure bottom is provided with supporting bracket, is used for whole dry cylindrical shell is in level.
In the utility model, the other drive motors that is provided with in drying side drives the spiral shaft by drive motors and rotates.
Beneficial effect: the utility model passes into Steam Heating and carries out drying between dry cylindrical shell and U-shaped dry slot, thermal medium with add that thermal material is non-directly to be contacted, ectocrine material physicochemical property not, simultaneously, double helix mechanism is set keeps the interior material of U-shaped dry slot to be heated evenly, and keeping circulation unimpeded, plant maintenance is changed convenient, long service life.
Description of drawings
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
Fig. 2 is the double-spiral structure figure of the utility model preferred embodiment.
Fig. 3 is the generalized section of the utility model preferred embodiment.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to Fig. 1, Fig. 2, double helix steam dryer shown in Figure 3, in the present embodiment, U-shaped dry slot 14 is positioned at dry cylindrical shell 1, be symmetrical structure, be provided with spiral shaft 13 in it, two spiral shafts 13 mesh by front end gear 6, and connect chain drive-belts 3 by upset end 5 and a little endoporus sprocket wheel 4 of, and connect reductor 2 by chain drive-belt 3.
External drive motors drives spiral shaft 13 by reductor 2, section forms circulation in the material within it, vapours then is filled with in two arc sandwiches between dry cylindrical shell 1 and the U-shaped dry slot 14 (referring to Fig. 3), dry cylindrical shell 1 outer the insulation, powder material carries out in the U-shaped dry slot 14 from feeding mouth 8, constantly circulation is heated between double helix shaft 13, to finish the drying and dehydrating process, in this process, can slide by two fans of both sides and observe door 11, observe in order to the degree of drying to its materials inside, and feed opening 10 places are provided with gate, after dry materials is finished, open the sluices, can under the promotion of spiral shaft 13, can finish self-emptying.
Simultaneously, in the present embodiment, dry cylindrical shell 1 top also is provided with cone cover 9, is provided with an extinguishing pipe with automatic temperature-controlled inductor on the cone cover 9 and meets and discusses, to guarantee security against fire.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
