Abstract

The utility model relates to a detachable melt filtering device for polyester fibre spinning equipment, comprising a cylinder 4, a filtering frame 7 arranged in the cylinder 4, and a small filter which is plugged on the filtering frame 7, wherein, the small filter 3 which has a hollow structure comprises a filtering core 9 processed with studded filtering openings, a filtering net 8 which is arranged out of the filtering core 9. The utility model is characterized in that the filtering net 8 is in star-shaped folding arrangement with taking the filtering core 9 as a center. Under the premise that the volume of the filtering device is not increased, the utility model increases the effective filtering area of the filter by ten times above, increasing filtering rate, and enhancing the yield and the quality of spinning. Simultaneously, the filtering net of the device can be detached to cleaned for repeated use.

Description

Detachable melt filtration device

The utility model relates to a kind of filter, relates in particular to a kind of melt filtration device of impurity screening from solidliquid mixture that is installed on the polyester staple fiber spinning equipment.

What polyester staple fiber was weaved most critical is the recycling rate of waterused height of raw material, even repeatedly utilizes.So repeatedly reuse has caused the impurity of polyester raw material to increase, and has increased the spinnability difficulty of raw material.And existing spinning equipment designs and produces than higher raw material according to cleaning, purity.So it is only in the screw rod squeeze bulb screen pack to be installed that the spinning of existing polyester staple fiber is filtered.And many little chemical fibre factories are that to reduce production costs be to utilize the leftover bits and pieces of big factory to come the reuse spinning, and raw material impurity content is than higher.Impurity all accumulates on the screen pack of screw head in the melt spinning process, need often to shut down platform and change the head screen pack, so that output is very low.So some little chemical fibre factory is before the screw rod extrusion is head and adorn the melt pre-filtrating equipment, this pre-filtrating equipment is made up of cylindrical shell, feed inlet and outlet and some small offence filters that is installed in the cylindrical shell.Little filter is a hollow structure, is processed with densely covered filter opening on its filter stamen, the full screen pack of filter stamen outsourcing.Melt pushes filter by pressure, makes it pass through the middle through hole of filter and flows out, and impurity is then stayed outside the screen pack.And remove the outer impurity of screen pack by the transposing filter.Because the screen pack of this pre-filtrating equipment directly is packaged in around the filter stamen, so filter area is little, the rate of filtration is slow, yields poorly.And change the screen pack that filter all need more renew, so use manufacturer production cost height at every turn.

The purpose of this utility model is to provide the detachable melt filtration that a kind of filter area is big and use cost is low device.

The utility model is achieved in that a kind of detachable melt filtration device that is used on the terylene spinning equipment, comprise cylindrical shell, be arranged on the filter stand in the cylindrical shell and be inserted into little filter on the filter stand, this little filter is a hollow structure, comprise the filter stamen that is processed with the filter opening that gathers, and being arranged on the outer filter screen of filter stamen, this filter screen is that the center is the collapsible arrangement of star with the filter stamen.

Filter screen of the present utility model is a three-decker, and one deck is thin screen pack in the middle of it, and inside and outside two layers are the coarse filtration net.

Be the support force of filter stamen in the middle of increasing, the utility model also can be provided with stamen in again in the filter stamen.

Compare with existing detachable melt filtration device, to be arranged to filter stamen be the collapsible arrangement architecture of star at center to the utility model owing to will filter the outer filter screen of stamen, under the prerequisite that does not increase the filter volume, the effective filtration area of filter has been increased more than ten times, accelerate the rate of filtration greatly, improved spinning output.Increase the flowability of melt simultaneously, reduced the finished product price reduction, improved product quality.Because the screen pack of this device detachably cleans the back repeated use, reduced the production cost that uses producer again.

Fig. 1 is a general structure schematic diagram of the present utility model.

Fig. 2 is the structural representation of little filter of the present utility model.

Fig. 3 is the A-A cutaway view of Fig. 2.

Below in conjunction with accompanying drawing the utility model being done one describes in detail:

As Figure 1-3, the utility model by cylindrical shell 4, be arranged on the filter stand 7 in the cylindrical shell 4 and the small offence filter 3 that is inserted on the filter stand is formed, small offence filter 3 is a hollow structure, comprise the filter stamen 9 that is processed with the filter opening that gathers, and being arranged on the filter screen of filtering outside the stamen 98, filter screen 8 is that the center is the collapsible arrangement of star with filter stamen 9.Consider the support force of filter screen 8, filter screen 8 is designed to three-decker, middle level one deck is the thin screen packs of 100 purposes, main filtration, skin is 30 purpose coarse filtration nets, mainly plays skeleton function, filters out the impurity of a part of larger particles simultaneously, internal layer is the thin screen packs of 24 purposes, mainly works to support the internal layer screen pack.The holding capacity of filter stamen 9 in the middle of being to increase, the utility model also can be provided with an interior stamen 10 that is processed with the filter opening that gathers again in filter stamen 9.

During work, the conduction oil in the heat tracing chamber 6 makes the temperature in the filter reach technological requirement.In separation process, at first be that melt is entered in the filter chamber 1 by charging aperture 2 by pressure, filter 3 is pushed, clean melt is discharged by discharging opening 5 by the through hole that in the middle of the filter is, fine impurity in the melt and gel particles are all stayed outside the screen pack 9, when the transposing filter contaminant removal are fallen.
