Abstract

The organization plan of a kind of contact drying and pneumatic conveying drying mixed type dynamic combined drying machine.Heating tube bundle 4, tube sheet 3,8, end socket 2,10 and rotating shaft 1,9 form integral rotor.Material is constantly dug by the rotor flight after entering drying machine, and it is pushed to outlet from inlet.The material one side contacts with heating tube bundle, absorbs the wet branch of heat of vaporization; Another side is implemented pneumatic conveying drying by 80～90 ℃ thermal air current.Rotor rotates with certain speed, and flight is constantly taken up material, causes the contact layer of bringing in constant renewal in heating tube bundle and material, can effectively avoid the material fouling.So this drying machine is applicable to that wet branch is high, and the drying of the easy fouling material of certain viscosity is arranged.

Description

Rotary tubulation drying machine

The utility model belongs to drying equipment.

Though drying equipment such as contact drier, thermal current drying machine etc. that tradition is used are relatively simple for structure, but be difficult to wet part high, viscosity big, easily the fouling material carries out effective dry and handles, and the thermal efficiency is low, energy consumption is high, it is heavy to stir operation, and particularly the material fouling will make dry run normally carry out.

Task of the present utility model provide a kind of be applicable to wet part high, viscosity big, the easy drying equipment of fouling material, reaches easy to operate, the thermal efficiency is high, the purpose of saving energy.The organization plan of a kind of contact drying and pneumatic conveying drying mixed type dynamic combined drying machine is proposed for achieving the above object.

Accompanying drawing is a structural representation of the present utility model.

With reference to the description of drawings organization plan:

As shown in drawings, this new structure characteristics be in the shell 6 heating tube bundles 4 respectively manage two ends respectively break-through and be fixed on steam admission side tube sheet 3 and exhaust region tube sheet 8 on, the Intake shaft 1 of heating tube bundle and tube sheet, end socket 2,10 and hollow and exhaust shaft 9 form the rotor of an integral body, be assembled with some angle steel at rotor edge, the flight 7 of changeable angle is installed on the angle steel.Quill shaft 1 one end M enter steam and discharge from an end N of quill shaft 9 through the internal channel of respectively managing of heating tube bundle 4.Air sucks in the housing from shell two ends ventilation eye, adds the thermosetting thermal air current through heating tube bundle and passes from storeroom, is discharged from exhaust outlet C by air-introduced machine again.Shell 6 is being offered material inlet A near steam inlet one upper lateral part, and material is constantly dug by flight, and discharge from the material outlet B that is opened in shell opposite side bottom dry back.

This programme advantage:

1. steam passes through in all pipes of heating tube bundle, and material contacts with heating tube bundle and absorbs wet part of heat of vaporization;

2. air enters from shell two ends ventilation mesh, is heated to 80～90 ℃, is extracted out by air-introduced machine from exhaust outlet C and forms the material enforcement pneumatic conveying drying of thermal current to constantly stirring.

3. rotor rotates with certain speed, and flight is constantly taken up material, causes the contact layer of bringing in constant renewal in tube bank and material, can effectively avoid the material fouling.The material that is stirred by the rotor flight constantly is pushed to outlet with material from inlet.

Claims

1. rotary tubulation drying machine, comprise shell, steam tube bundle, the two ends that it is characterized in that each pipe of the interior heating tube bundle of shell (6) (4) break-through and be fixed in steam admission side tube sheet (3) and exhaust region tube sheet (8) respectively, tube sheet (3), (8), end socket (2), (10) with admission axle (1), steam discharge axle (9) forms a rotor integral body, at rotor edge assembling some angle steel (5), uniform some flights (7) on it, axle (1) is a hollow, (M) enters steam from its end, flow through behind each root pipeline of heating tube bundle, discharge from the end (N) of quill shaft (9), air is inhaled into from the shell two ends, discharge from exhaust outlet (C) by exhaust blower more excessively from the storeroom percolation through adding the thermosetting thermal current, shell (6) has material inlet (A) on the top near steam inlet one side, and has material outlet (B) at the end near the steam discharge outlet.

2. drying machine according to claim 1 is characterized in that flight (7) changeable angle.
