Abstract
A liquid phase tackified screw pump comprises a shell body provided with a feed inlet and a feed outlet, a screw rod installed in inner shell body and a drive system. The characters are that the screw rod is a uniaxial tackified screw rod. A spinning melt booster pump is connected with the feed outlet of shell body. The screw rod adopts a double-channel screwing rhombus structure to transport materials. In the theory of traditional screw extruder metering section liquid phase transportation, the end of feed outlet is retrofitted with a large slope of feeding device. Switching to use the way of double-channel screw rod can increase the material transferring quantity to ensure the constants of high viscosity materials' output pressure. The liquid phase tackified screw pump is reasonable in structure. The liquid phase tackified screw pump can solve the insoluble problem which the high viscosity materials can't be continuously transmitted in the existing production process and achieve to recycle a part of production model of bottle flakes PET spinning aggregation - spinning. And the use of the liquid phase tackified screw pump improves the production efficiency, and reduces the energy consumption and largely saves the production cost. At the same time, the liquid phase tackified screw pump also can be applied to the transmission of other high-viscosity object which includes the PBS (Phosphate Buffered Saline), the nylon 66, the nylon 6, the high modulus polyethylene and the like.
Description
Technical field
The utility model relates to a kind of screw-rod delivery pump, and is specifically a kind of for the continuous liquid-phase tackifying screw pump of carrying of high-viscosity material, is used for the conveying that PET spins industrial filament production process liquid-phase tackifying material.
Background technology
The purposes of screw-rod delivery pump is very wide, relates to numerous industrial circles, such as chemical field, mining and metallurgy field, food processing etc.It is 201210028830.6 Chinese patent " a kind of vacuum screw-rod delivery pump " such as the patent No., comprise the feed cavity and the discharging chamber that are interconnected, the top of feed cavity is provided with charging aperture, the end in discharging chamber is provided with discharging opening, wherein, be connected with vacuum chamber at the opposite side of feed cavity with respect to the discharging chamber, vacuum chamber is provided with air bleeding valve, run through successively vacuum chamber and feed cavity by motor-driven screw rod, screw rod is provided with conveyor screw.But this at screw-rod delivery pump in continuous flow procedure, still can't solve the problem of the continuous conveying of high viscosity (kinematic viscosity is more than 0.8) material.
For these reasons, in reclaiming bottle sheet PET spinning process, can't finish at present a method production model of polymerization-spinning, generally all be to adopt two-step method production: low viscosity PET section-SSP solid-phase tack producing-pre-crystallized, drying-screw rod melting-spinning, complex procedures so not only, and energy consumption is high, production cost is also high, and is more difficult beyond doubt with regard to extremely low PET bottle sheet returned enterprise for original profit.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of liquid-phase tackifying screw pump simple and reasonable, continuously transfer of highly viscous material for the above-mentioned state of the art, to realize a method production model of polymerization-spinning in the reclaiming bottle sheet PET spinning process.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of liquid-phase tackifying screw pump, comprise the housing that is provided with charging aperture and discharging opening, be arranged on screw rod and transmission system in the housing, it is characterized in that: described screw rod is single shaft tackify screw rod, is connected with a spinning melt booster pump at the discharging opening of housing.
As improvement, described screw rod is to adopt dual channel spiral shell water chestnut structure convey materials.
As improvement, described charging aperture is positioned at the upper end of housing, and described discharging opening is positioned at the middle and lower part sidepiece of housing, and the feeding device on a large inclined-plane is installed on the charging aperture, and the head of described screw rod is placed through in the feeding device, forms a spiral agitator.
Improve, described feeding device is one to vacuumize reactor again.
Further improve, the charging aperture lower end sidepiece of described housing offers the heating agent export and import of the heating jacket of screw pump.
At last, described transmission mechanism is the gear-box of a translator, is located on the base of housing lower end, and the output of gear-box is connected with single shaft tackify screw rod by connecting axostylus axostyle.
Compared with prior art, the utility model has the advantage of: on the principle that traditional screw extruder metering section liquid phase is carried, install the feed arrangement on large inclined-plane at feed end additional, use simultaneously dual channel tackify approach screw instead and strengthen output pressure constant that the material transport fluxes guarantees high-viscosity material.The utility model is rational in infrastructure, existing production procedure medium-high viscosity (kinematic viscosity is more than the 0.8) material of solution can't solve the problem of continuous conveying, to realize a method production model of polymerization-spinning in the reclaiming bottle sheet PET spinning process, greatly improved production efficiency, reduced energy resource consumption simultaneously and significantly save production cost, the utility model is not only applicable to PET and spins industrial filament, also applicable to the conveying of other high viscosity objects such as PBS, nylon 66, nylon 6, high modulus polyethylene etc.
