Description

The method that is used to make the collecting chamber of mineral fibres and makes mineral fibres
Technical field
The preamble of claim is described as described later, the present invention relates to the method that is used to make the collecting chamber of mineral fibres and makes mineral fibres.
Background technology
Mineral wool such as asbestos is made at melt in furnace by for example suitable raw materials such as diabase, limestone or slag.This mineral melt is discharged to fiber-forming device with the form of melt jet from smelting furnace, in this fiber-forming device, melt forms mineral fibres.Usually use the fiber-forming device of spinning machine type, the fiber-forming device of this spinning machine type comprises a series of fine rotating cylinder (rotor) or the spinning rotating cylinder of being rotated into, and typically is three to four rotating cylinders.Mineral melt directly is directed to the mantle surface (mantle surface) of first rotating cylinder from smelting furnace, and mineral melt is dished out mantle surface with second rotating cylinder in a series of rotating cylinders against this, contiguous as dripping string before, herein to a certain degree to grasp the mantle surface of this first rotating cylinder.This mineral melt of a part grasps the mantle surface of this second rotating cylinder securely then, to form fiber by action of centrifugal force.Another part mineral melt is further dished out with the mantle surface against the 3rd rotating cylinder.By this way, on the jet flow of string is dripped or dripped to mineral melt with mineral melt form " is transported " subsequently a rotating cylinder from a rotating cylinder successively, thereby by whole fiber-forming device, the while part of mineral melt forms mineral fibres.During fiber forms or after fiber forms, can on the mineral fibres that forms, smear binding agent.
Becoming the mineral fibres that forms on the fine rotating cylinder to be transported out from fiber-forming device by blowing off.Blowing off of mineral fibres can come together to carry out by so-called primary blow-off means or with secondary air separation plant, and this primary blow-off means is positioned in the periphery of rotating cylinder, this secondary air separation plant and fiber-forming device setting separated by a distance.Mineral fibres is transported towards collecting member by collecting chamber from fiber-forming device, and this collection member is arranged on the place ahead of fiber-forming device.Collecting member for example can be conveyer belt or swing roller.
Mineral fibres is collected as thin web of fiber usually, that is, and and so-called primary fibre web or primary web.Primary fibre web is collected by the perforated surface that moves usually, and this surface forms the collection surface of collecting member.If the fibre weight that flows out is a constant, then collect the surface weight that the speed of advancing on the surface can limit collected primary fibre web from fiber-forming device.The speed of collecting the surface is high more, and collected primary web is thin more, and surface weight is low more.Common target is to collect thin as far as possible primary mineral fibre webs.When collecting web of fiber, the entanglement and the cluster of mineral fibres are not expected, because will cause the quality of final products to descend like this.Certainly also expectation can be avoided producing hole in collected primary mineral fibre webs.
When the amount of the mineral fibres of being produced by fiber-forming device increased, the gathering speed of described collection member must improve on same degree ground, so that the surface weight of collected primary web remains unchanged, and the surface weight of this width of cloth is unlikely and becomes excessive.Yet the speed of collection member is subjected to the restriction of other follow-up in technological process devices and can not arbitrarily improves.Because the thin width of cloth is fracture easily in the process of transporting, and may overlap, therefore the post processing of not only thin but also fast primary mineral fibre webs has been proved to be complicated.
Mineral fibres move to from fiber-forming device collect member during, the condition in the collecting chamber is very big to the influence of the structure of collected primary web.If the flox condition in the collecting chamber is disorderly, and exist reverse whirlpool (back-eddies), then collected primary web to beat joint and inhomogeneous easily.When the output of fiber increases, become fine process and collection process also to become and be difficult to control.
It is important optimizing each sub-process in the manufacture process of mineral wool, thereby obtains desirable final products.Verifiedly be difficult to from this fiber-forming device manufacturing and collect a large amount of fibers and do not make the structure of collected primary web and the deterioration of formed mineral wool.
Mineral wool has many different purposes, for example is used as insulating materials in various structures.According to its purposes, the performance (as its intensity, compressibility etc.) of the mineral wool of manufacturing there is different requirements.The performance of mineral wool is subjected to the Effect on Performance of single mineral fibres, in other words, is subjected to thickness, length and aspect-stabilized influence of the single fiber in the mineral wool.When mineral fibres can influence these performances by flow to the condition that is produced when the air-flow of collecting member transports from collecting chamber.Air communication is crossed blowing off of the air separation plant that is positioned on the fiber-forming device and is collected the suction of component surface and form.In these conditions, also rotate owing to be rotated into the feasible part air of fine rotating cylinder, thereby the reverse whirlpool and the air whirl that form in collecting chamber especially are a problem around this rotating cylinder near this rotating cylinder.
The increase of mineral fibre production amount need increase and is used for mineral fibres is transported to the required air capacity of collecting chamber from fiber-forming device.The air capacity that increases in the collecting chamber makes and produces the risk increase of piling the debatable air whirl of (transporting towards collecting member from fiber-forming device) around fiber.Simultaneously, owing to must remove the amount of the gas of (usually by collecting the surface of member) increase from collecting chamber, thereby must strengthen suction.
Traditionally, collecting chamber forms big " box-shaped ", and the first end of this collecting chamber is arranged in the fiber-forming device, and the second end of this collecting chamber is arranged on to be collected in the member.The cross section of the first end of collecting chamber is traditionally arranged to be the cross section less than the second end.
Summary of the invention
Therefore, the method and apparatus that the purpose of this invention is to provide the manufacturing mineral wool fiber of the above-mentioned defective of a kind of energy minimization.
For realizing this purpose, be provided with a kind of collecting chamber, the structure that this collecting chamber had helps to make fiber not pass this collecting chamber to be transported to the collection member with producing whirlpool.
Another object of the present invention is to realize a kind of method, can minimize or prevent the formation of reverse whirlpool by this method.
The method and apparatus of the feature that characteristic proposed by having appended independent claims can be realized purpose of the present invention.
Typical collecting chamber according to the present invention comprises: first end, and it is towards fiber-forming device, and this fiber-forming device is made mineral fibres with mineral melt; The second end, it is towards collecting member, and described mineral fibres is transported to this collection member by air-flow from this fiber-forming device; Between this first end and this second end, be provided with: roof, and the first side wall and second sidewall.The cross section of this first end of this collecting chamber has first area, the cross section of this second end of this collecting chamber has second area, and the cross section of described this first end and the cross section of this second end are limited by this roof, this first side wall and this second sidewall and the cutting plane of lower limb of rotating cylinder that flatly contacts the least significant end of this fiber-forming device.This collecting chamber comprises waist, this waist is arranged between this first end and this second end, and the length of this waist is at least 100mm, and the cross section of this waist has the 3rd area, the 3rd area is bigger by 10% than described first area at the most, and less than described second area.
The method according to this invention typically may further comprise the steps:
-mineral melt guiding is comprised that first of at least two fiber-forming devices that become fine rotating cylinders are rotated into fine rotating cylinder;
-mineral melt is thrown the mantle surface of the second rotation rotating cylinder from the mantle surface of this first rotation rotating cylinder, and further throw the mantle surface of rotating cylinder that may exist, subsequently from the mantle surface of this second rotation rotating cylinder;
-mineral melt forms mineral fibres described being rotated on the fine rotating cylinder;
-by fibre blow-off means with the mineral fibres that forms the fine rotating cylinder of described one-tenth from this fiber-forming device, pass described collecting chamber and blow off towards described collection member, this collecting chamber comprises: first end, it is towards this fiber-forming device, this first end has first area; The second end, it collects member towards this, and this second end has second area; Roof between this first end and this second end, and the first side wall and second sidewall limit this first area and this second area with cutting plane, this cutting plane flatly contact the lower limb of rotating cylinder of the least significant end of this fiber-forming device; And
-by being arranged on the waist between this first end and this second end, the formation of the reverse whirlpool in this collecting chamber of energy minimization, the length of this waist is at least 100mm, and the cross section of this waist has the 3rd area, described the 3rd area is bigger by 10% than described first area at the most, and less than described second area.
We are surprised to find now, and by in fiber-forming device with collect between the member and form collecting chamber, and this collecting chamber has waist, can greatly reduce the reverse whirlpool that forms between member and the fiber-forming device collecting.Waist forms mechanical constraint, and this mechanical constraint has reduced collects the reverse whirlpool that forms between member and the fiber-forming device.Because the flox condition of the fine end of the one-tenth of collecting chamber is the few eddy current of multilayer stream, the condition of transporting fiber from fiber-forming device that therefore forms in this manner is than before stable more and evenly.
Count from the most approaching edge that becomes fine rotating cylinder, the collecting chamber operated by rotary motion is preferably the position of 350-450mm at the about 300-700mm in the place ahead of fiber-forming device.Usually at this position calculation first area, promptly collecting chamber is towards the area of section of the end of fiber-forming device.According to embodiment, distance between the rotating cylinder on the first end of collecting chamber and the top of fiber-forming device is set to less than the distance between the rotating cylinder of the bottom of the first end of collecting chamber and fiber-forming device, fine device with respect to the angled location of the first end of collecting chamber.
According to the present invention, between the first end of collecting chamber and the second end, be provided with waist, the length of this waist is at least 100mm, and the cross section of this waist has the 3rd area, and the 3rd area is bigger by 10% than first area at the most, and less than second area.Waist can be set to be positioned at the collecting chamber end, towards the passage or the path of fiber-forming device upward opening, promptly in the fine end of the one-tenth of collecting chamber.Therefore waist forms the fiber control part of collecting chamber.The part that is positioned at waist and the second end of collecting chamber can be called the fibre forming portion of collecting chamber.
The present invention can advantageously combine with the fiber-forming device of aforesaid string type.Such fiber-forming device generally includes three to four and is rotated into fine rotating cylinder, and the fiber along continuous straight runs is blown off towards collecting member from the rotating cylinder that rotates.
According to the present invention, this waist has certain length, and this length is at least 100mm, and the cross section of this waist has certain area, and this area is all the time less than second area.Can expect that this waist forms the tubular pipeline such as air duct, mineral fibres and air communication are crossed this waist and are flowed to the collection member from fiber-forming device.The top of waist can be circular, so the similar semicanal of this waist.The sectional area of waist can increase on the direction of collecting member gradually, so the inclination angle of the roof of waist and/or sidewall is usually less than 5 °.The roof inclination angle of collecting chamber can become very precipitous at waist final position place, and in other words, the inclination angle of roof generally is at least 20 °.According to one embodiment of present invention, has discontinuous point in the position that waist stops and fibre forming portion continues.
The cross section of waist can be smaller or equal to first area.In other words, also can be towards position that waist stops and reduces with the position that combines of the fibre forming portion of collecting chamber in the waist cross section.This amount that reduces is less relatively usually, and the inclination angle of the roof of waist is usually less than 5 °.According to preferred embodiment, the cross section of waist remains unchanged on the whole length of waist.
According to embodiments of the invention, the length of waist can change in the scope of 1150mm at about 150mm, typically is 200mm-1100mm, is 200mm-800mm more typically, is preferably 150mm-600mm.Length according to the waist of another embodiment changes in the 400mm-1000mm scope, typically is 500mm-1100mm, is 500mm-800mm more typically, is preferably 550mm-700mm.
According to embodiments of the invention, waist can comprise the adjusting interface and the adjustment means of the length that is used to change waist.Adjustment means for example can be an overlapping interface and can manual operation or operation automatically.When the length of waist changes, the also physical alterations of the length of collecting chamber, the distance from the fiber-forming device to the gathering-device also correspondingly changes thus.According to embodiments of the invention, fiber-forming device and the distance of collecting between the member are generally 0.75-5.5m, are preferably 1.5-2.75m.This distance also can typically be 2.5-3.5m between 1.5-5m.
The fibre forming portion of collecting chamber is streamlined usually, and its roof can form towards collecting chamber at the second end and is arc downwards.By independent, movable top wall portion, can with the end of the roof of collecting chamber and fibre forming portion (that is, and roof, with the surperficial immediate part of collecting chamber) between distance be set to adjustablely, this top wall portion is set to contact with the roof of reality.By this movable top wall portion, itself and the distance of collecting between the member change between 40-400mm usually, typically are 100-300mm.
Distance between the first side wall of collecting chamber and second sidewall forms the inner width of the fibre forming portion of collecting chamber.This width is identical with the collection width of collecting part usually.
