Description
Technical field
The utility model relates to a kind of suction system, relates in particular to a kind of monomer suction system, is used for the extrusion spinning production line.
Background technology
In prior art, in the extrusion spinning production line, due to the characteristic of polycaprolactam self, when molten condition, having low-molecular-weight oligomer in polycaprolactam is that monomer will be separated out.These oligomer and monomer volatilize after melt is extruded spinnerets, meet very easily forming white powder near spinnerets and be attached under spinneret face after cold, cause spinning condition to worsen.
Chinese patent 200920116104.3 discloses a kind of monomer pumping device.Present aspirator suction maldistribution, suction effect is bad.The utility model comprises the shrinking hood of suction hood and the trapezoidal cabinet of rectangular box, and the docking station of shrinking hood is communicated with the open rearward end of suction hood, and the contraction mouth of shrinking hood is communicated with negative tube.Be provided with deflector in suction hood and shrinking hood, deflector is perpendicular to bottom surface and the end face setting of suction hood and shrinking hood, the part of deflector in suction hood and the parallel sided of suction hood, the part of deflector in shrinking hood is according to the shrinkage direction setting of shrinking hood.This structure is too simple, and result of use is relatively poor, affects the suction of monomer, can further affect spinning condition.
The utility model content
The utility model is mainly to solve the deficiencies in the prior art, and is simple in structure, at each top of spinning a quenching air window, monomer suction cover has been installed all, prevents the monomer suction system that spinning condition worsens.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of monomer suction system, comprise the pump housing, be provided with the operation cavity in the described pump housing, be provided with the cycle of higher pressure (operating) water nozzle in the described pump housing, described cycle of higher pressure (operating) water nozzle extends in the operation cavity, and the sidewall of the described pump housing is provided with and is attached thereto logical monomer suction cover.
Low polymer and monomer that the rough vacuum that monomer suction cover utilizes water stream injection pump to produce will evaporate from the melt thread are drawn in pipe-line system, by recirculated water, oligomer and monomer are delivered in the monomer suction circulating water chennel, filter and remove oligomer and the monomer of carrying secretly in recirculated water, wherein contained gas is separated enters in atmosphere, the soakage that can regulate smog by regulating water stream injection pump intake pressure and flow.
As preferably, the top of the described pump housing is provided with the upper flange that fixes with it, and the top of described cycle of higher pressure (operating) water nozzle is to the upper flange extension, seals mutually by upper sealing ring between described cycle of higher pressure (operating) water nozzle and upper flange.
As preferably, the bottom of the described pump housing is provided with mutually integrated lower flange with it, and described cycle of higher pressure (operating) water nozzle and monomer suction cover are 90 degree right angles and distribute.
As preferably, locate mutually by bearing between described cycle of higher pressure (operating) water nozzle and the pump housing, seal mutually by lower seal between described cycle of higher pressure (operating) water nozzle and the pump housing.
Therefore, monomer suction of the present utility model system, compact conformation, easy to operate, the improving product quality, is increased work efficiency at extension device service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
