Detailed description of the invention
Referring to figs. 1 through Fig. 2, the utility model chemical fibre melting plant embodiment is described further.
A kind of chemical fibre melting plant, comprise sleeve 1, transfer roller 2, heater 3, charging aperture 4 and discharging opening 5, by charging aperture 4, granular polymer is added in melting plant, utilize the transfer roller 2 be arranged in sleeve 1, with the delivery device that transfer roller 2 is arranged, in the process that transfer roller 2 rotates, granular polymer is carried to discharging opening 5 one end from charging aperture 4 one end, simultaneously, sleeve 1 outer wall is also provided with heater 3, make polymer in course of conveying, by the contact with sleeve 1 inwall, by the melt that granular polymer melting is in a liquid state, again through discharging opening 5, be delivered to spinning manifold, spray silk is carried out shaping by the measuring pump in spinning manifold and spinnerets, form thread fiber product.In melting process, because polymer enters in melting plant with granular form, likely can because of melting not fully or after melting, impurity etc. is there is in melt, when spray silk will be caused shaping, spinnerets blocks, and short grained impurity then can cause the problems such as the structural strength of chemical fibre is inadequate.
Melting can be carried out more fully in melting plant to make polymer, transfer roller 2 is divided into feeding section 21, melt zone 22 and transportation section 23 from charging aperture 4 one end successively to discharging opening 5 one end, and on conveying roller 2 other end of feeding section 21 relative melt section 22 adapter sleeve, be connected to outside sleeve 1 by connecting axle 26, and connecting axle 26 is connected with drive motors, connecting axle 26 is driven to rotate by motor, thus drive conveying roller 2 to rotate, connecting axle 26 matches with the inwall of sleeve 1, avoids granular polymer from feeding section 21 connecting axle 26 side conveying relatively.The outer surface of sleeve 1 relative melt section 22 is provided with heater 3, in heater 3, is connected with thermal medium, by the heat trnasfer between thermal medium and sleeve 1, when making the polymer of sleeve 1 inside be sleeve 1 interior contact, realize melting.Preferably, thermal medium is chosen as hot-air, and the flow direction of hot-air in heater 3 is contrary with the transmission direction of sleeve 1 interpolymer, by the hot-air of reverse circulated, can make polymer in transmitting procedure, after the polymer advanced person of melt zone 22 near one end, transportation section 23 crosses preliminary melting, inner may exist fail the polymer of complete melting, and hot-air and polymer reverse flow, the preferential polymer contact with entering preliminary melting of hot-air being made, improving melting effect.
Simultaneously, delivery device is set to screw thread, and feeding section 21, melt zone 22 and transportation section 23 are provided with screw thread, by the setting of screw thread, while transfer roller 2 rotates, polymer can be carried towards discharging opening 5 one end, achieve the effect that melting realizes together with transmitting function, and the pitch of melt zone 22 and transportation section 23 screw thread is less than the pitch of melt zone 22 screw thread, feeding section 21 is provided with the screw thread of coarse pitch, during energy, polymer is carried faster in feeding section 21, and the situation preventing particle from blocking, melt zone 22 and transportation section 23 arrange the less screw thread of pitch, when polymer is delivered in melt zone 22 in feeding section 21, by the pitch diminished, pressure can be produced to polymer, make the distribution that polymer is more intensive, reduce the transmission speed of polymer in melt zone 22 simultaneously, make its melting more abundant.
In order to better realize melting, after avoiding melting, the inner polymer for complete melting enters in transportation section 23, feeding section 21 diameter is made to be less than transportation section 23 diameter, melt zone 22 diameter increases to one end, transportation section 23 gradually from feeding section 21 one end, and melt zone 22 two ends diameter is identical with the diameter of transportation section 23 with feeding section 21 respectively.When polymer transmits in melt zone 22, by the diameter increased gradually, the enable polymer that makes extrudes towards sleeve 1 inwall, polymer is fully contacted with sleeve 1, abundant melting, can also make granular polymer be stuck between transfer roller 2 and sleeve 1, avoids the particle of subsidiary non-melting in melt.
In the polymer, usually can mix with some other granular impurity, if impurity is brought in manufacturing procedure, the quality of product will be affected to a great extent, therefore, the fillter section 24 for filtering-depositing impurity is provided with between melt zone 22 and transportation section 23, fillter section 24 and junction, transportation section 23 are provided with filter screen 25, filter screen 25 rounded and filter screen 25 outer rim and sleeve 1 inwall are to coordinating, filter screen 25 is arranged on the junction of transportation section 23 and fillter section 24, melt in melt zone 22 after melting, be sent in fillter section 24 before this, fillter section 24 part transfer roller 2 diameter is less than transportation section 23 diameter, fillter section 24 part is made to form the space being used for carrying out sedimentation and filtration, granular impurity does not have along with polymer together melting in melt zone 22, when entering in fillter section 24, because polymer melting is in a liquid state, impurity is subject to the impact of gravity in melt, can precipitate in melt, therefore, fillter section 24 is set out larger space, melt flowing velocity in fillter section is reduced, better the impurity that inside is contained is precipitated.Simultaneously, filter screen 25 is arranged on the junction of fillter section 24 and transportation section 23, to make after melting melt in fillter section 24 by after the contamination precipitation of inside, again by one deck filter screen 25, further removal of impurities is carried out to melt, makes the melt that obtains purer, and be delivered to transportation section 23 melt evenly, after melting plant melting can be kept, stablizing of the melt flow transferred out.By the impurity that filter screen 25 filters, and the impurity precipitated in fillter section 24, go out removing by the impurity pipe 11 be arranged on bottom sleeve 1.In transmission shaft rotation process, the impurity be attached on filter screen 25 can fall down, by impurity pipe 11, impurity is flowed out in fillter section 24, impurity pipe 11 is provided with valve 12, under normal circumstances, valve 12 is in closed condition, and regular opens valve 12, by the impurity removing precipitated in fillter section 24, keep the pure of melt, melting is efficient.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
