Abstract
The utility model relates to a predrying device used for carrying out predrying to industrial by-product gypsum powder in the production of paper surface gypsum boards, which comprises a hot air furnace (1), a dust cleaning device and a revolving drying device (2), wherein the hot air furnace (1) is communicated with the revolving drying device (2) through the dust cleaning device, and after fuel burns in the hot air furnace (1), hot air is produced and directly passes through the dust cleaning device and enters the revolving drying device (2) to carry out the predrying to the industrial by-product gypsum powder in the revolving drying device (2) Therefore, the utility model has the characteristics of uniform drying, quick dehydration, high output, little energy consumption, etc.
Description
Technical field
The utility model is a kind of prebake device that the industry by-product gypsum powder is carried out prebake in Thistle board production.
Background technology
In recent years, utilized industry by-product gypsum to produce Thistle board, produced Thistle board, improved environment, reduced cost, paid close attention to by people because of it utilizes industrial waste phosphogypsum, desulfurated plaster.Because water content is higher in the industry by-product gypsum, need carry out the prebake dehydration, and the domestic equipment that is used for prebake mainly adopts pipe bundle drier or the coal-fired same rotary kiln that heats at present, its shortcoming is the energy consumption height, yields poorly, the bad control of dries quantity.Though the external hot-air seasoning that adopts, speed is fast, output is high, and its energy consumption is far above domestic, and the oven dry of industry by-product gypsum powder is inhomogeneous, can not adapt to suitability for industrialized production.
Summary of the invention
The purpose of this utility model provides a kind of prebake device of industry by-product gypsum powder, and it has oven dry evenly, and dehydration is fast, output height, characteristics such as energy consumption is low.
For achieving the above object, the technical scheme that the utility model is taked is: be made up of hotblast stove, cleaning apparatus, rotary drying machine etc.Hotblast stove is communicated with rotary drying machine by cleaning apparatus.Fuel directly enters rotary drying machine at the hot blast that produces after the hotblast stove internal combustion after the cleaning apparatus dedusting, the industry by-product gypsum powder in the rotary drying machine is carried out prebake.
Rotary drying machine is made up of feeding unit, revolving cylinder, motor, wheel box, rotary drive mechanism etc.Revolving cylinder by an end of hotblast stove be provided with blast inlet, the other end is provided with discharge port and air outlet, be provided with screen cloth at discharge port, be provided with raising material unit in the revolving cylinder, motor connects with slewing gear by wheel box, and slewing gear connects with revolving cylinder.
The hot blast that hotblast stove produces is after the cleaning apparatus dedusting, blast inlet by revolving cylinder enters, material in the revolving cylinder is dried, need the industry by-product gypsum powder of oven dry to add revolving cylinder by feeding unit, under the effect of raising material unit, kick up, also fully contact with hot blast, dried, sift out through discharge port then.
For material is fully dried in revolving cylinder, raising material unit can be formed a plurality of liftings zone by the material delivering plate of multiple structure formation and combine in revolving cylinder, as claw type, cruciform shape, parallel X-type, arc etc.Like this, the industry by-product gypsum powder is subjected in revolving cylinder under the effect of raising material unit, is fully kicked up and pulverizes, and fully contact with hot blast, makes the prebake better effects if, and the heat energy of hot blast is utilized better.
Because the utility model adopts hot blast to be directly used in oven dry after dedusting, the industry by-product gypsum powder is kicked up by raising material unit in revolving cylinder, fully contact with hot blast, improved the utilization ratio of drying effect and heat energy, therefore the utlity model has oven dry evenly, dehydration is fast, output height, characteristics such as energy consumption is low.
Description of drawings
Fig. 1 is the utility model synoptic diagram,
Fig. 2 is a revolving cylinder inwall synoptic diagram.
Embodiment
Accompanying drawing is an embodiment of the present utility model, is made up of hotblast stove (1), cleaning apparatus, rotary drying machine (2) etc.Hotblast stove (1) is communicated with rotary drying machine (2) by cleaning apparatus.Fuel directly enters rotary drying machine (2) at the hot blast that hotblast stove (1) burning back produces after the cleaning apparatus dedusting, the industry by-product gypsum powder of rotary drying machine (2) lining is carried out prebake.
Hotblast stove (1) can be a Coalhotairfurnace, also can be the hotblast stove of fuel oil or combustion gas.
Rotary drying machine (2) includes feeding unit (6), revolving cylinder (7), motor, wheel box, rotary drive mechanism compositions such as (8).Revolving cylinder (7) by an end of hotblast stove (1) be provided with blast inlet, the other end is provided with discharge port and air outlet, be provided with screen cloth (9) at discharge port, revolving cylinder is provided with raising material unit in (7), motor connects with slewing gear (8) by wheel box, and slewing gear (8) connects with revolving cylinder (7).Raising material unit includes the material delivering plate of multiple structure formations such as claw type, cruciform shape, parallel X-type, arc and forms the multiple lifting zone of formation.
The hot blast that hotblast stove (1) produces is after the cleaning apparatus dedusting, blast inlet by revolving cylinder (7) enters, need the industry by-product gypsum powder of oven dry to add revolving cylinder (7) by feeding unit (6), under the effect of raising material unit, kick up, fully contact with hot blast and dried, sift out through discharge port then.
Therefore, the utlity model has oven dry evenly, dehydration is fast, output height, characteristics such as energy consumption is low.
Claims (3)
