Abstract

The utility model relates to a drying rotary kiln composed of a driving mechanism and an outer barrel connected to the driving mechanism. The drying rotary kiln is characterized in that an inner barrel is additionally arranged in the outer barrel; second epoxy layers are pasted at inlaid positions at two ends of the inner barrel and the outer barrel; a copying board is arranged on the inner wall of the inner barrel; the outer barrel, the inner barrel and the copying board are fixedly connected through bolts and nuts; and a first epoxy layer is pasted at a gap among the copying board, the bolts and the inner wall of the inner barrel. The drying rotary kiln is applied to a drying device in chemical industry, the inner barrel made of glass fiber reinforced plastics is additionally arranged on the inner side of the outer barrel, the tightness of the gap between the outer barrel and the inner barrel is guaranteed by the epoxy layers, therefore water and gas containing acid and chloride ion are prevented from entering the gap between the outer barrel and the inner barrel, the outer barrel is prevented from being corroded, and the service life of the outer barrel is prolonged.

Description

Dry rotary kiln

Technical field

The utility model relates to a kind of inorganic salts drying equipment, especially relates to a kind of outer cylinder body dry rotary kiln in service life that is applied in the chemical products drying, prolongs.

Background technology

Dry rotary kiln is a kind of important chemical equipment, extensively should be in industries such as chemical industry of inorganic salt, metallurgy.

In the rotary kiln of Traditional use hot-air drying, include material inlet, the hot blast import; The rotary kiln cylindrical shell, material outlet, hot-blast outlet and rotary kiln driving mechanism etc.; Wherein, the rotary kiln cylindrical shell adopts stainless steel material to make usually, and the tube inwall is welded with multi-form poplar materials devices such as flight.

Generally speaking; The use stainless steel cylinder can satisfy the requirement of most of materials, but for the material that contains acid and chlorion, corrodes because acid and chlorion can produce stainless steel; Particularly at high temperature; Can accelerate corrosion rate, add long-term the washing away of material, can reduce the service life of rotary kiln cylindrical shell greatly; Simultaneously, because stainless thermal conductivity factor is bigger, heat loss is bigger in the dry run; In addition, because the impurity that corrosion produces also can be sneaked into product, reduce product quality in the dry run.

Summary of the invention

The utility model technical problem to be solved provides the generation of avoiding poly-doped impurity in the dry run, and prolongs the outer cylinder body dry rotary kiln in service life simultaneously.

The technical scheme that is adopted that the utility model solves its technical problem is: a kind of dry rotary kiln; Comprise driving mechanism and be connected the outer cylinder body on the driving mechanism; Left end at outer cylinder body is respectively equipped with material inlet and hot blast import; This material inlet is below the hot blast import, and the right-hand member of said outer cylinder body is respectively equipped with material outlet and hot-blast outlet, and this material outlet is below hot-blast outlet; Be equipped with inner core in the said outer cylinder body; The place's paste of inlaying at said outer cylinder body and inner core two ends has second epoxy layer; This inner core inwall is provided with flight; Said outer cylinder body, inner core and flight are fixedly connected through screw bolt and nut, and stick with paste the gap of said flight, bolt and inner core inwall has first epoxy layer.

Wherein, said outer cylinder body is basic stainless steel, and inner core adopts the fiberglass reinforced plastics material to make; Adopt the Monel material for screw bolt and nut, have anticorrosion ability.

Further, said flight becomes bending-like, guarantees the materials inside uniform drying.

The beneficial effect of the utility model is: this structural design is applied to the drying equipment in the chemical industry; Be equipped with the inner core of fiberglass reinforced plastics material in the inboard of outer cylinder body; And through the gap sealing between epoxy layer assurance outer cylinder body and the inner core; Water, the gas of having avoided containing acid and chlorion get into the interlayer between outer cylinder body and inner core, prevent that outer cylinder body is corroded, and prolong the service life of outer cylinder body.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the internal structure sketch map of outer cylinder body and inner core in the utility model;

Fig. 3 is the enlarged diagram of the A part among Fig. 2.

Among the figure: 1, outer cylinder body 2, inner core 3, bolt 4, nut 5, flight 6, first epoxy layer 7, second epoxy layer 8, hot blast import 9, material inlet 10, driving mechanism 11, material outlet 12, hot-blast outlet.

The specific embodiment

A kind of dry rotary kiln shown in Fig. 1-3; Comprise driving mechanism 10 and be connected the outer cylinder body 1 on the driving mechanism 10; Left end at outer cylinder body 1 is respectively equipped with material inlet 9 and hot blast import 8; This material inlet 9 is below hot blast import 8, and the right-hand member of said outer cylinder body 1 is respectively equipped with material outlet 11 and hot-blast outlet 12, and this material outlet 11 is below hot-blast outlet 12; Be equipped with inner core 2 in the said outer cylinder body 1; This inner core 2 adopts fiberglass reinforced plastics to make; The place's paste of inlaying at said outer cylinder body 1 and inner core 2 two ends has second epoxy layer 7, and these inner core 2 inwalls are provided with flight 5, and this flight 5 adopts Monel material; Said outer cylinder body 1, inner core 2 are fixedly connected with nut 4 with the bolt 3 of flight 5 through the Monel material, and stick with paste the gap of said flight 5, bolt 3 and inner core 2 inwalls has first epoxy layer 6.

Further, 5 one-tenth bending-likes of said flight guarantee the materials inside uniform drying.

This structural design is applied to the drying equipment in the chemical industry; Be equipped with the inner core 2 of fiberglass reinforced plastics material in the inboard of outer cylinder body 1; And through the gap sealing between epoxy layer assurance outer cylinder body 1 and the inner core 2; The water, gas of having avoided containing acid and chlorion gets into the interlayer of 2 of outer cylinder body 1 and inner cores, prevents that outer cylinder body 1 is corroded, and prolongs the service life of outer cylinder body.
