Description

A kind of four roller whizzers for the rock wool fiberizing system

Technical field

The utility model belongs to the energy-saving heat preserving field, is specifically related to the Technology equipment of asbestos product production field.

Background technology

Asbestos product is to take natural rock to be main raw material, the fireproof energy-saving heat insulation material of making through melting furnace high temperature melting, fibrosis applying glue processing, felt plate curing molding and goods post-treatment.Asbestos product, with its good heat-insulating property, fire resistance and sound-proof sound-absorbing performance, is widely used in industries such as building, oil, chemical industry, electric power, metallurgy, communications and transportation, agriculturals.

The premium properties of the fibroblast quality guarantee asbestos product that stable fiberizing system is become reconciled, the fibroblast equipment adopted in the rock wool fiberizing system at present is whizzer normally, also there is small portion to adopt four roller whizzers, the four roller whizzers that adopt at present comprise roller No. one, No. two rollers, No. three rollers, No. four four Centrifugal rollings such as roller, four Centrifugal rolling diameters are the 180-230 millimeter, wherein a Centrifugal rolling becomes 100-125 ° of angle with the line of centres of No. four Centrifugal rollings with sea line, and with No. three Centrifugal rolling lines of centres, become 75-90 ° of angle with No. two Centrifugal rollings, layout and size design problem due to four Centrifugal rollings, thereby cause centrifugal force can not guarantee the quality of fibroblast fully, the slag ball can not effectively separate.And this four roller whizzers adopt the large flow cooling water of enclosed to carry out cooling Centrifugal rolling; make melt cooling fast on Centrifugal rolling; cause the slag ball many; the fibroblast rate is low; fibroblast is of poor quality; with often leaking because Centrifugal rolling processes installation quality, cause water content in fiber to affect greatly postorder processing and quality product.Existing four roller whizzers also have a defect, the blast of producing by boasting from vane exactly is low, wind direction disperses, easily cause fibroblast of poor quality, and the quantity of glue spraying mouth is few, the atomization quality of glue is poor, and be that vertical Centrifugal rolling end face blows forward after ejection, can only spray into above the part fiber, cause fiber quality bad, glue spraying is inhomogeneous simultaneously.

Summary of the invention

The purpose of this utility model is to solve the defect that existing four roller whizzers bring, and a kind of four roller whizzers for the rock wool fiberizing system are provided, and makes its fibroblast quality good, and energy-conserving and environment-protective more.

The utility model adopts following technical scheme to realize:

A kind of four roller whizzers, comprise frame and be arranged on a Centrifugal rolling on frame, No. two Centrifugal rollings, No. three Centrifugal rollings, No. four Centrifugal rollings, a Centrifugal rolling diameter is 160-190mm, No. two Centrifugal rolling diameters are 223-250mm, No. three Centrifugal rolling diameters are 300-325mm, No. four Centrifugal rolling diameters are 310-340mm, No. one Centrifugal rolling becomes 50-63 ° of angle with the line of centres of No. four Centrifugal rollings with sea line, and with No. three Centrifugal rolling lines of centres, become 87-95 ° of angle with No. two Centrifugal rollings, described four roller whizzers also comprise and are arranged on Centrifugal rolling No. two, No. three Centrifugal rollings, No. four three outer vanes of Centrifugal rolling, three vanes respectively are provided with a spraying gun outward, spraying gun is provided with more than one glue spraying mouth.

On the end face of a described Centrifugal rolling, No. two Centrifugal rollings, No. three Centrifugal rollings, No. four Centrifugal rollings, be provided with more than one steam outlet, make and only need to continue from a small amount of water coolant of the internal feed of each Centrifugal rolling, after water coolant absorbs the temperature of Centrifugal rolling, form steam and discharge Centrifugal rolling.Still less, energy-conserving and environment-protective, make the temperature of Centrifugal rolling cooling even to this open steam type of cooling water, is more conducive to fibroblast, if unlike enclosed, process bad meeting, leaks, thereby affect fiber quality.Preferably steam outlet is inclined hole, vergence direction is the axis direction that deviates from the place Centrifugal rolling, and become the angle of 55--75 ° with the end face of place Centrifugal rolling, can not affect like this fibroblast direction and the centrifugal fibroblast mode of fiber, the mist drawn can be distributed uniformly in fiber, further improve the fibroblast quality.

On described three vanes, be provided with a countervane that above vergence direction is consistent with the Centrifugal rolling sense of rotation, after the countervane guiding, wind-force is more concentrated from vane wind out, and effectively blast is higher.

Glue spraying mouth on described spraying gun be towards Centrifugal rolling that spraying gun encloses axially, and with the Centrifugal rolling end face, become 40-70 ° of angle.Glue spraying is more even like this, and the fiber quality of formation is good.

The utility model advanced technology, reasonable in design reliable, greatly improved fibroblast quality and the fibroblast rate of fiber, strengthen uniformity of size application, effectively reduce the content of slag ball.The cooling water inflow of Centrifugal rolling greatly reduces, and energy-conserving and environment-protective.Have the advantages such as simple in structure, easy to operate.
