Abstract

The utility model relates to a drum-type drying device and belongs to the field of material drying. The drum-type drying device comprises a drum, an air intake pipe and an air exhaust pipe, wherein hot air enters into the drum through the air intake pipe and exchanges heat with the materials in the drum, so as to dry the materials; the hot air flows out through the air exhaust pipe; the drum-type drying device further comprises a heating pipe and connecting devices for the air intake pipe and the air exhaust pipe; the heating pipe is arranged in the drum and is fixedly connected with an inner wall of the drum; the connecting devices for the air intake pipe and the air exhaust pipe have same structures; each of the connecting devices comprises a shell and a drum connector; the drum connector is fixedly connected with the drum; the shell is mounted on the exterior of the drum connector and is in clearance fit with the drum connector, so as to form an annular airtight space for the drum connector rotating relative to the shell; through holes are formed in the shell and are respectively communicated with the air intake pipe and the air exhaust pipe; and through holes formed in the drum connector are respectively communicated with an air inlet and an air outlet of the heating pipe. The drum-type drying device achieves the purpose of drying without pollution on the materials, through the indirect heating action of the medium inputted to the heating pipe on the materials.

Description

A kind of drum type drying apparatus

Technical field

The utility model relates to a kind of material drying device, relates in particular to a kind of drum-type material drying unit.

Background technology

at present, in production, the drying mode of widely used drum type drying apparatus has two kinds of direct oven dry and indirect dryings.Direct drying mode, cylindrical shell rotates, and material is kicked up by lifting blade, sends into hot blast heating material is made to moisture evaporation, by the blower fan of afterbody, the steam evaporating in cylindrical shell is taken away.There is following problem in this drying mode: thermal source can only be hot blast and can not be hot gas, have limitation, material directly contacts with thermal current, and the pollutant in thermal current can cause the pollution of material, thereby, for requiring to have the oven dry of the material of pollution must adopt the mode of indirect drying to carry out.And existing indirect drying mode, rotating cylinder consists of concentric drums, concentricity requirement is high, place after lifting blade, drying unit is bulky, if volume-diminished cannot be installed lifting blade again, lifting blade is not installed and can be made again production capacity decline, so this drying unit floor space is large, investment is many, the thermal efficiency is low.

Utility model content

The utility model has overcome shortcoming of the prior art, provides a kind of, by the heating tube being arranged in cylinder, material has been carried out to the drying unit of conduction heating indirectly, realizes the pollution-free oven dry to material.

The technical scheme that the utility model is realized goal of the invention employing is: a kind of drum type drying apparatus, comprise cylinder, air inlet pipe, escape pipe, heat-exchange device, it is characterized in that, heat-exchange device comprises heating tube, air inlet pipe jockey, escape pipe jockey, heating tube be arranged in cylinder and be fixedly connected with inner wall of rotary drum hot gas from air inlet pipe enter in cylinder with cylinder in material carry out heat exchange material drying, from described escape pipe, flow out;

Described air inlet pipe jockey, the structure of escape pipe jockey are identical, include shell and cylinder connector, shell and cylinder connector are loop configuration, shell is provided with gas flow through hole, cylinder connector is provided with through hole, shell is arranged on outside cylinder connector, forms annular confined space, and shell and cylinder connector form the structure that cylinder connector opposite shell is rotated;

Described cylinder connector is fixedly connected with cylinder, and the inlet end of heating tube is communicated with air inlet pipe by the through hole of the cylinder connector of air inlet pipe jockey, the gas flow through hole of shell; The outlet side of heating tube is communicated with escape pipe by the through hole of the cylinder connector of escape pipe jockey, the gas flow through hole of shell; Heating tube is longitudinally evenly arranged along inner wall of rotary drum; Shell and cylinder connector are pegged graft, and adopt matched in clearance sealing and sealing block sealing; Described sealing block is slip graphite block.

The beneficial effects of the utility model are: this device is by being arranged on heating tube in cylinder to material indirect, and pollution-free in drying course, under the identical condition of output, this device volume is little, efficiency is high, small investment.

Below in conjunction with accompanying drawing and the specific embodiment, the utility model will be further described.

Accompanying drawing explanation

Accompanying drawing 1 is structural representation of the present utility model;

Accompanying drawing 2 is the A portion partial enlarged drawings in accompanying drawing 1.

In accompanying drawing, feed hopper 1, cylinder 2, air inlet pipe 3, air inlet pipe jockey 4, shell 4-1, cylinder connector 4-2, sealing ring 4-3, escape pipe jockey 5, wheel are with 6, travelling gear 7, heating tube 8, mount pad 9, pipe clamp 10, exhaust pipe 11, discharging bin 12, escape pipe 13.

The specific embodiment

As shown in drawings, the present embodiment is a kind of drum type drying apparatus, by feed hopper 1, cylinder 2, air inlet pipe 3, air inlet pipe jockey 4, escape pipe jockey 5, wheel be with 6, travelling gear 7, heating tube 8, mount pad 9, pipe clamp 10, exhaust pipe 11, discharging bin 12, escape pipe 13 form, described heating tube 8 is arranged in cylinder 2 and is fixedly connected with cylinder 2 inwalls by mount pad 9, pipe clamp 10, and heating tube 8 is longitudinally evenly arranged along cylinder 2 inwalls; Cylinder 2 outer surfaces are provided with air inlet pipe jockey 4 and escape pipe jockey 5, the two structure is identical, include shell 4-1 and cylinder connector 4-2, shell 4-1 and cylinder connector 4-2 are annular structural part, cylinder connector 4-2 is fixedly connected with cylinder 2, and shell 4-1 is arranged on the outside of cylinder connector 4-2, and shell 4-1 and cylinder connector 4-2 are connected structure, adopt matched in clearance sealing and sealing block sealing, sealing block is slip graphite block 4-3.
