Description
Technical field
The utility model relates to a kind of centrifugally glass-wool forces decker online.
Background technology
China's industrial solid castoff stacking amount is up to more than 70 hundred million tons according to statistics, approximately 600,000,000 square metres of appropriation of land, and wherein cullet has accounted for 13% of solid waste total amount, and also will increase more than 3,000 ten thousand tons of cullet every year newly.Because cullet both non-degradable also can't burn, can only landfill, not only account for land resource and spoiled soil structure, the environmental loss that brings can't be estimated.
The main path that China's cullet is recycled is that cullet is reclaimed rear raw material as producing low-grade glass, and some is used for preparing flame cotton and centrifugal cotton.Centrifugally glass-wool is that the glass that will be in molten condition carries out the filamentary material that fibration is made at 1000 ℃ with centrifugal injection method technique, optionally spray thermosetting resin, process through the heat cure deep processing again, have the plurality of advantages such as fire-retardant, nontoxic, corrosion-resistant, that unit weight is little, thermal conductivity factor is low, chemical stability is strong, hydroscopicity is low, hydrophobicity is good, can be made into the series of products that serve many purposes, be insulation, heat insulation, the sound-absorbing material that generally acknowledged at present best performance is got over, have very widely purposes.
U.S. Patent number is that the patent of invention of US 6862901 B1 discloses a kind of technique and device of producing glass fibre.This patent Introduction use centrifugal injection technology to prepare the design main points of the devices such as the process of glass fibre and spinning head hole diameter size, fiber drawing furnace, and inquired into the performance impact to centrifugally glass-wool such as glass fibre density, diameter distribution, glass metal viscosity.
Publication number is that the patent of invention of CN1619038A discloses a kind of mixing centrifugally glass-wool fibrofelt and method for making thereof.This microglass fiber felt is by centrifugally glass-wool and inorfil or organic fiber compositions of mixtures, and the large and insulation of intensity and fire resistance are excellent.
Publication number is that the patent of invention of CN1563542A discloses a kind of composite centrifugal microglass fiber felt and method for making thereof.This characteristic feature of an invention is to add blowing device or anti-curling device at the centrifugally glass-wool production equipment, solidifies simultaneously preparation composite centrifugal microglass fiber felt in same curing oven.
Publication number is the preparation method that the patent of invention of CN102351413A discloses a kind of A level fire protection flame retarding energy saving ultrafine glass wool.It is raw material that dull and stereotyped cullet, feldspar powder, soda ash, borax decahydrate and borax pentahydrate are selected in this invention, adopts centrifugal injection technology to make glass wool.But the prepared centrifugal glass fibre of this method is whole shape, is not the glass wool of layering, and heat insulation and sound absorption properties can be affected in use.
The centrifugally glass-wool felt mainly is as main take single-layer glass fiber at present.When centrifugal injection method system was cotton, glass metal was introduced continuous glass flows thigh in the narrow meshed sedimentator of High Rotation Speed by passage, becomes glass wool through centrifugal action with the combustion flame drawing-off.Glass wool forms the unordered staggered shape glass fibre that interts in the decline process, descent path is tortuous, finally forms porosity up to 70%～80% single-layer glass fiber layer at cotton collecting machine.
Compound glass cellucotton felt mainly assimilates the single-layer glass fiber layer processing such as deep processing by heat, cut rear mutual stack according to actual requirement and form.Yet the interlamellar spacing of compound glass cellucotton felt is fairly obvious, causes the excessive phenomenon of cotton felt porosity.When heat, sound etc. in glass fibre cotton felt transmittance process, the impurity such as dust granules can circulate by bedding void, affect thermal insulation, the sound absorption qualities of cotton felt, so that thermal conductivity factor raises, chemical stability reduces, finally cause the inefficacy of glass fibre cotton felt.
The utility model is intended to overcome because the excessive phenomenon of porosity between multilayer that glass layer causes cotton carpet veneer that superposes, force online decker at a kind of centrifugally glass-wool of porous carrier bar cotton collecting machine conveyer belt design that glass fibre distributes, when cotton fiber falls to conveyer belt, along the conveyer belt direction of motion the most inboard spinning head jet the glass fibre cotton that forms through thickness hierarchical control plate to its stop and extruding, form the more flat bottom laminated glazing cellucotton of thickness; The bottom glass fibre cotton is along with the transmission of conveyer belt, drop on the bottom glass wool through the formed glass fibre cotton of outside sedimentator, and again by thickness hierarchical control panel assembly glass fibre cotton is carried out compression process, finally form the cotton felt blank of centrifugal glass fibre of AUTOMATIC ZONING.
The utility model content
The purpose of this utility model is intended to overcome the deficiencies in the prior art, provide a kind of and forced online decker at a kind of centrifugally glass-wool of cotton collecting machine porous chain plate conveyor belt design, so that the formed glass fibre cotton of the inboard spinning head of the conveyer belt direction of motion is pressed into the bottom glass fibre cotton, spinning head formed glass wool in the outside then is pressed on the bottom fiber, form the centrifugally glass-wool felt blank of layering, then process the cotton felt of the centrifugal glass fibre that obtains AUTOMATIC ZONING through solidifying deep processing.
For realizing that the technical scheme that the purpose of this utility model adopts is: provide a kind of centrifugally glass-wool to force online decker, it is characterized in that this device is fixed on the cotton collecting machine, is positioned in the middle of the adjacent spinning head.
