  • the invention relates to a device for producing synthetic fiber materials with a feed for a polymer melt to a rotating hollow reactor, the wall of which is heatable and for guiding a melt film to one open side, which can be closed with a lid, expanded conically and with ribs to divide the melt film into those that solidify after exiting the hollow reactor Fibers is provided.
  • Such synthetic fibers can be used in particular as absorbents be made from water petroleum and petroleum products as well as a number of Can filter out heavy metal ions.
  • thermoplastic fibers take place regularly in two stages, namely extraction of the melt and formation of the fiber.
  • thermoplastic material is first melted and then the melt is extruded through spinnerets to form the fibers.
  • a System known from SU 1 236 020 A has a loading bunker, a power supply and a melting grid with a distributor for heated Inert gas. The distributors are triangular and even over the Distributed melting grid surface.
  • the thermoplastic to be processed Material is in the space above the grid up to the melting temperature evenly heated and can flow freely between the triangular distributors undergo treatment with nitrogen.
  • connection points for the assembly of heating elements are connection points for the assembly of heating elements. As a result, the heated material is melted and continues to reach one Worm drive, is pushed through the nozzles and into a strand or one Thread formed.
  • fibers can only be made from high quality Raw materials are produced, it must be ensured that the raw material in steady speed on the melting grid and then on the melt the screw arrives for removal.
  • the energy source a higher temperature than the destruction temperature of the polymer and a have sufficient speed to make the melt strands thinner and longer and thus can be formed into a fiber.
  • the open pool of the reactor causes a loss of energy and leads to a reduced effectiveness of the Manufacturing process.
  • a plant for the production of fibrous materials is also known from RU 2 061 129, which form an extruder, a fiber-forming ring head with radially arranged and in the center converging channels, an air flow generator that the At the same time, the melt strands are drawn out and cooled until they become fibers and has an element for separating the finished fiber that has an extension converging in the direction of the incoming thread.
  • the fibers are deposited under the action of a stream of air flowing in Direction of the extruded melt strands is directed.
  • the radially arranged and Channels converging in the center also require the use of high quality Raw materials. Otherwise, these channels will not be completely melted Block the mass, causing it to pass through the fuse lines is difficult. The manufacture of high quality fibers less high quality raw materials is therefore not possible.
  • a device of the type mentioned at the outset is known from RU 2 117 719, at which heats a horizontally mounted rotating cylindrical hollow reactor from the outside becomes.
  • the open part of the reactor has the shape of an expanding cone, which is closed with an immovable cone cover.
  • the cone cover forms a gap opening with the lateral surfaces of the expanding cone from 15 to 20 mm.
  • flat ribs attached which have a triangular shape along their length, the along the fiber formation and with the tip towards the melt flow exit is aligned.
  • the device is with an annular high pressure air supply equipped.
  • Solid parts of the polymer can be carried away from this standstill zone and under the influence of the centrifugal forces together with the melt transported to the end of the reactor and discharged together with the fiber become solid, making the fiber more uneven with thickening or inclusions unmelted pieces of various shapes are formed, the quality of the fiber is reduced.
  • the system must be cleaned regularly to clean the standstill zone stopped to mechanically remove the adherent polymer. If the reactor walls were heated more, this would lead to an essential one Overheating of the melt film.
  • Another disadvantage of the known device is that just over 30% of the thermal energy supplied is immediate is used for heating the tape. The rest, given by the heater Energy is used to heat the inside of the reactor and the ambient air consumed by transmission of radiation energy.
  • the present invention has for its object a device for manufacturing to improve synthetic fiber materials of the type mentioned at the beginning, that achieves an increased fiber quality with a reduced energy consumption becomes.
  • This object is achieved according to the invention in a device of the type mentioned at the outset solved in that the hollow reactor is aligned vertically and a steady curved inner wall and an opening for the curved top Has supply of the polymer melt and that a rotating opposite the opening Distribution plate arranged at a short distance from the inner wall is.
  • the device according to the invention is for producing a uniform thin Melting film formed, which extends to the open side of the reactor due to the steady Curvature of the inner wall can move without standstill zones.
  • Training of the uniform thin melt film is achieved by the polymer melt axially on the curved top of the hollow reactor through an opening is fed and arrives there on a rotating distributor plate, which in one short distance from the inner wall of the hollow reactor is arranged. This will the molten polymer fed is collected and by centrifugal force hurled evenly onto the inner wall of the hollow reactor.
  • the distributor plate thus forms a closure of the feed opening to form an annular gap with the inner wall of the hollow reactor, from which the on the distributor plate collected material emerges evenly distributed and on the inner wall of the Hollow reactor arrives.
  • the flow rate of the melt film on the inner wall of the hollow reactor due to the rotation of the hollow reactor resulting centrifugal force and additionally by the weight of the melt film determined because the hollow reactor is oriented vertically and open downwards.
  • the distribution effect of the distributor plate is further improved in that the Surface of the distributor plate rises towards the edge, preferably one towards the opening pointing concave curved top forms.
  • a truncated cone is arranged on the distributor plate, its diameter is smaller than the diameter of the distributor plate. The diameter the top of the distributor plate in the order of the diameter correspond to the opening of the feeder.
  • the continuously curved inner wall of the hollow reactor is preferably parabolic formed, corresponds to the surface created by the rotation of a parabola the own axis arises.
  • Outlet opening arises from the constant curvature compared to the previously known Device a significantly reduced internal volume, so that the required Amount of heat energy reduced for heating the interior.
  • the invention Construction also minimizes heat loss and specific Heat consumption.
  • the inner wall forms with a surrounding container of the hollow reactor a curved Gap to which a steam supply and a steam discharge is connected. Due to the constant circulation of heated water vapor through the formed Cavity, a uniform heating of the reactor walls is achieved. Consequently it is possible to make the melting tape or the melting film with a uniform Produce temperature and thickness, which unites the fiber over the entire length has a uniform diameter and contains no unmelted parts.
  • the steam supply and the steam discharge are arranged at the top and bottom of the inner wall. The steam can both in cocurrent and in countercurrent to the direction of transport Polymer melt are performed. The arrangement in direct current is preferred.
  • the device shown in the drawing is used to produce fibers a thermoplastic melt and includes a vertically installed rotating one Hollow reactor 1 in the form of a paraboloid, which by rotating a parabola around the own axis is formed. At the open edge of the paraboloid there is an as expanding cone provided edge 2 provided. Centric is in the curved Part of the paraboloid formed an opening 3 for feeding a polymer melt.
  • the inner wall of the hollow reactor 1 is provided with flat ribs 4 which run perpendicular to the edge 2 in the lower region of the hollow reactor 1.
  • the hollow reactor 1 is located in a surrounding container 5, in the surface thereof is adapted to the shape of the hollow reactor 1, so that a curved Gap 6 results.
  • the gap 6 is in its upper part with the exit and in its lower part connected to the input of a steam generator 7, so with the gap 6 forms a closed steam cycle.
  • the direction of movement of the water vapor is illustrated by arrows in FIG. 1, with a direct current movement of water vapor is formed.
  • the Steam generator 7 can be used in the same way and for some applications also sensibly implement a countercurrent direction of the water vapor.
  • the distribution device consists of a Truncated cone 11 and an attached distributor plate 12, the Diameter is larger than the base of the truncated cone 11. Truncated cone 11 and Distribution plates 12 are firmly connected to one another, preferably in one piece. The ring of the distributor plate projecting radially beyond the truncated cone 11 12 is provided with a surface that rises towards the radial edge and forms such a concave curved top.
  • the hollow reactor 1 is at the lower open end by a disc-shaped cover 13 closed.
  • the flat ribs 4 are connected to the edge of the cover 13, so that there are outlet openings between the ribs.
  • the hollow reactor is attached to the end of a hollow shaft 14 which rotates on bearings 15 is stored.
  • the bearings 15 are located in a housing 16 to be cooled.
  • a drive pulley 17 for transmitting the rotation, for example, from an asynchronous (not shown) Engine arranged.
  • the reactor For the production of fibrous materials, the reactor is supplied before being put into operation brought from circulating steam in the gap 6 to working temperature. Because the water vapor flow has a constant temperature and speed has, the heating of the inner wall of the hollow reactor 1 takes place over its entire Even surface. The heat flow is from the heated surface of the Hollow reactor 1 released to the inside and thus generates the required temperature throughout the interior and keeps it constant. This creates a homogeneous temperature field on the entire surface of the hollow reactor 1.
