Description
Technical field
The utility model relates to a kind of center for rock wool production line whizzer glue spraying structure, belongs to field of mechanical technique.
Background technology
The principle of work of rock wool production line whizzer is: the Centrifugal rolling rotating speed of whizzer is 4000-6700 rpm, to the circumference of+30o, the resin glue nozzle is installed at four Centrifugal rolling periphery+120o, the resin glue nozzle is to the center spray binding agent of four Centrifugal rollings, axially there is pressurized air each Centrifugal rolling periphery by certain angle ejection, trickled to the radial surface of four Centrifugal rollings of high speed rotating by the melt of the l200～l500 of cupola melting ℃, be combined with binding agent under compressed-air actuated effect at centrifugal force and form fiber.
Through production after a while with grope, recognized for the fine and closely woven degree that sprays binding agent and be sprayed at the uniformity coefficient of zone of positive pressure, to becoming cotton to have a great impact, due to present technique be the binding agent nozzle in periphery the center spray binding agent to four Centrifugal rollings, binding agent will be through the zone of positive pressure of the peripheral axial compression air of each Centrifugal rolling, the final center that could arrive four Centrifugal rollings, cause binding agent to be greatly affected in the uniformity coefficient of zone of positive pressure, on becoming the cotton amount also to produce impact, for overcoming above-mentioned factor, improve the rock wool quality, we have improved the spray-bonding craft technology.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of center for rock wool production line whizzer glue spraying structure is provided.
The utility model solves the technical scheme that its technical problem adopts:
A kind of center for rock wool production line whizzer glue spraying structure, comprise Centrifugal rolling and centrifugal shaft, described Centrifugal rolling is fixedly connected with the centrifugal shaft bolt, the central position, end of Centrifugal rolling is provided with installation opening, described installation opening is fixedly connected with the seven-star built up nozzle, described centrifugal shaft is axially arranged with the glue spraying pipe along center, the exit end of described glue spraying pipe dynamically is connected with the entrance end of seven-star built up nozzle, between described glue spraying pipe and Centrifugal rolling, also is fixed with for preventing the sealing-ring of cooling water leakage in the Centrifugal rolling cavity.
As preferably, described pilot hole is provided with internal thread, and the seven-star built up nozzle is threaded with pilot hole.
As preferably, described glue spraying tube end has been socketed with the first copper nut and second copper nut of supporting glue spraying pipe effect, and described sealing-ring is located between the first copper nut and the second copper nut, and the first copper nut is fixedly connected with the seven-star built up nozzle with the second copper nut.
As preferably, described glue spraying pipe is stainless steel tube.
As preferably, described sealing-ring is silicone rubber O-ring.
In whizzer, the radially-outer surface of Centrifugal rolling is the melt of l200～l500 ℃, Centrifugal rolling and centrifugal shaft are fixedly connected with bolt, the water coolant that in the cavity of section is circulation within it carrys out cooling Centrifugal rolling, in order to meet Centrifugal rolling center glue spraying, separately add a glue spraying pipe at the center of every centrifugal shaft, the glue spraying pipe is static, directly seven-star built up nozzle outside through the Centrifugal rolling center and the Centrifugal rolling end face is rotationally connected, a well sealing must be arranged like this between glue spraying pipe and Centrifugal rolling, otherwise water coolant can mix ejection along outer wall and the resin glue of glue spraying pipe, cause in rock wool water content large, the curing oven that plays dry setting effect just can not make products solidifying be shaped, can't produce the rock wool product of high-quality, to solve radial seal under high rotating speed, selecting suitable sealing material is the most important thing, find that silica gel sealing ring is the sealing material that wear resistance is good, and a large advantage of silica gel sealing ring is exactly good springiness, can make up the gap of diameter run-out, price is cheap again, therefore determine to adopt silica gel sealing ring, wearing and tearing had both been solved, made up again the radius clearance problem that diameter run-out brings, in order to give the strong supporting of a glue spraying Guan Jiayi reliability, consider to add individual than the supporting of rigidity, so design is supported with the first bronze medal locknut and the second copper nut, silica gel sealing ring is located between the first copper nut and the second copper nut, the first bronze medal locknut and the second copper nut are supported with its certain superiority: even the Centrifugal rolling jerk value is large, the first bronze medal locknut contacted also and can not cut off the glue spraying pipe with the glue spraying pipe with second copper nut moment, in addition, the first bronze medal locknut and the second copper nut play a part to compress silica gel sealing ring, and material is soft, end face easily and silica gel sealing ring be adjacent to, so both solved supporting and sealing, prevented again that pitch tube was cut off, and designed when the first copper nut and the second copper nut are conducive to fastening and maintenance and dismantle.
The application of whizzer Centrifugal rolling center glue spraying structure, greatly improved uniformity coefficient and the area coverage of binding agent at zone of positive pressure, when melt trickles radial surface to four Centrifugal rollings of high speed rotating, the seven-star built up nozzle of Centrifugal rolling end face sprays forward binding agent by certain angle simultaneously, under effect due to centrifugal force, melt is drawn as filament and forms fiber, be looped around radial surface the place ahead of four Centrifugal rollings, pressurized air is the axial ejection from four Centrifugal rollings by certain angle, force the fiber forward impelling, form continuous production.
The beneficial effects of the utility model are: the utility model is rational in infrastructure, and binding agent can be uniformly distributed at zone of positive pressure, can effectively improve into the cotton amount.
