Abstract
The utility model relates to a kind of strengthening counter-current steam rotary dryer, comprise: rotating cylinder, Steam Heating tube bank is set in the inside of rotating cylinder, Steam Heating tube bank is connected with vapour axle by each branched pipe, Steam Heating tube bundle support is on the helical blade of adverse current, and the helical blade of described adverse current is welded on the barrel of rotating cylinder.The utility model drying machine adds the time of contact that dried material and Steam Heating are restrained, improve filling rate, and extend the time of staying of material, material with take wet gas current and contact fully, compared with the steam rotary dryer of routine, drying efficiency significantly improves.
Description
Technical field
The utility model relates to drying device technical field, relates in particular to a kind of strengthening counter-current steam rotary dryer.
Background technology
Steam rotary dryer be with a kind of take steam as the indirect heat-exchange rotation formula drying equipment of thermal source, be applicable to the drying of the wet powder material of the industries such as metallurgy, environmental protection, chemical industry, building materials.As: powdered copper concentrate, Iron concentrate, nickel fine powder, coal dust, desulfurated plaster, sodium sulfite etc.Steam Heating tube bank in existing steam rotary dryer adopts annular collet to support, and does not arrange flight, and the filling rate of material is little, and takes wet gas current and contacts insufficient, causes the problems such as drying efficiency is low, residence time of material is short, yield poorly.
Utility model content
The purpose of this utility model is to solve the problem, provide a kind of strengthening counter-current steam rotary dryer, this drying machine can increase the time of contact of dried material and steam-heating pipe, improves filling rate, make material and take wet gas current and contact fully, drying efficiency is high.
For achieving the above object, the utility model adopts following technical scheme:
A kind of strengthening counter-current steam rotary dryer, comprise: rotating cylinder, Steam Heating tube bank is set in the inside of rotating cylinder, Steam Heating tube bank is connected with vapour axle by each branched pipe, Steam Heating tube bundle support is on the helical blade of adverse current, and the helical blade of described adverse current is welded on the barrel of rotating cylinder.
In the inner side of the barrel of described rotating cylinder, some flights are set.
Described rotating cylinder is bearing in rolling ring, and power set driving gear astragal moves rotating cylinder and rotates.
The exhaust end of described rotating cylinder arranges discharge cover.
The discharging opening of described feed screw is arranged on the center of rotating cylinder.
The arrival end of described rotating cylinder arranges charging aperture and air inlet respectively.
The beneficial effects of the utility model are:
The utility model drying machine adds the time of contact that dried material and Steam Heating are restrained, improve filling rate, and extend the time of staying of material, material with take wet gas current and contact fully, compared with the steam rotary dryer of routine, drying efficiency significantly improves.
Accompanying drawing explanation
Fig. 1 is the utility model strengthening counter-current steam rotary dryer structural representation.
Wherein, 1. feed screw, 2. charging aperture, 3. air inlet, 4. rotating cylinder, 5. rolling ring I, 6. flight, 7. Steam Heating tube bank, 8. spiral adverse current blade, 9. gear ring, 10. rolling ring II, 11. discharge cover, 12. vapour axles
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
A kind of strengthening counter-current steam rotary dryer, as shown in Figure 1, the inside of its rotating cylinder 4 arranges Steam Heating tube bank 7, Steam Heating tube bank 7 is connected with vapour axle 12 by each branched pipe, Steam Heating tube bank 7 is supported on the helical blade 8 of adverse current, the helical blade 8 of adverse current is welded on the barrel of rotating cylinder 4, the barrel of rotating cylinder 4 is provided with several flights 6, rotating cylinder 4 is bearing on rolling ring I5 and rolling ring II10, the arrival end of rotating cylinder 4 arranges charging aperture 2 and air inlet 3 respectively, power set drive gear ring 9 to drive rotating cylinder 4 to rotate, the exhaust end of rotating cylinder 4 arranges discharge cover 11, the discharging opening of feed screw 1 is arranged on the center of rotating cylinder 4.
The dried material technique of strengthening counter-current steam rotary dryer is:
1) material to be dried enters into rotating cylinder 4 from feed screw 1, be heated by steam tube bank 7 heat drying, and kick up under the effect of cylindrical shell flight 6, shed, material in the process fallen with take humid gas and fully contact, material toward discharge end movement is subject to the effect of spiral adverse current blade 8, reduce translational speed, add the time of staying, dried material enters discharge cover 11 and discharges;
2) heating steam enters from the vapour axle 12 of rotating cylinder 4, enters into multi beam pipe through each lateral, and by multi beam pipe, heating material is dry, dried condensed water is discharged by drainage system.Take humid gas to be entered by air inlet 3, after fully contacting with material in rotating cylinder, discharged by exhaust outlet in discharge cover 11.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
