Description

Spinning melt filter device

Technical field

The utility model belongs to apparatus for melt spinning technical field, and in particular to a kind of spinning melt filter device.

Background technology

As is known in the industry, melt spinning produces polyester fiber, need to be i.e. molten in the melt output end corresponding to screw extruder Two filter devices of filter device and generally use are arranged in the position of body extruding end, and each filter device has strainer, served as When the impurity adhered on the strainer of filter device is more, the normal filtration to melt can be influenced.Due to using two filter devices, because And can ensure the uninterrupted filtering to melt by way of switching, such as when the aforementioned strainer on a filter device is by impurity Severe blockage and when implementing cleaning, then being taken over by another i.e. filter device for being in standby, to not appear in To interrupting the situation to melt filtration during the filter screen cleaning of blocking.

The technical information of spinning melt device can be seen in disclosed Chinese patent literature, typically such as " Intelligent double-tube double-pole melt filter " that CN201857445U recommends, although the patent formula can embody specification the The technique effect of 0012 section of record, but according to the description of the 0019th to 0023 section of the patent specification, due to needing to use First, second cartridge filter, thus structure is relative complex and volume is big.

More typical " projecting hook production equipment and its melting such as the CN106182794A offers of application for a patent for invention publication No. Body filter device and the manufacturing method for projecting hook ", the positive effect of the patent application is：It will be by screw rod by melt filter The contaminant filters such as remaining dust in the melt of extruder melting extrusion remove the impurity in melt and use raising and project hook The quality of product.The structure of melt filter that the patent application scheme is recommended is：In two piston boits of hydraulic device（Specially Profit claims " upper movable axis and lower movable axis "）A through-hole respectively above and in position to correspond to each other is opened up, the detachable card in through-hole A piece of strainer is connect, strainer forms strainer vessel with the piston boit place of being connected, i.e. strainer is located in strainer vessel, and strainer vessel corresponds to In melt into and out of between channel（For details, reference can be made to the 0031st section of the patent specifications）.The patent application scheme exists as follows Shortcoming：First, due to needing to open up the strainer vessel for strainer is arranged on piston boit, thus increase entire hydraulic mechanism Structural complexity；Second, through being detachably clamped strainer repeatedly, once the aforementioned strainer vessel on piston boit is due to the factors such as abrasion When being difficult to obtain the suitable effect with strainer, strainer will produce loosening or deformation, influence the filtering to melt, in addition will appear because Strainer deviates from strainer vessel and blocking in melt into and out of at channel, increases difficulty to inspection；Third, since strainer is detachable It must be just able to by means of corresponding tool when being connected in the strainer vessel being opened on piston boit, thus taking out cleaning It evicts strainer from strainer vessel, and there is the anxiety for undermining strainer by net with tool.

In addition, when textile melts are polylactic acid melt, high temperature is easily degraded due to being, thus melting sources, Requiring melt in the link of conveying etc, residence time is as short as possible in a device, it is desirable that the smooth arrival spinneret of melt, in Be replace strainer speed must be fast it is again fast.

For above-mentioned prior art, the applicant has made beneficial design, forms technology described below finally Scheme and in the case where taking secrecy provision through computer simulate deduce experiment be proved to be practicable.
