Abstract

The utility model relates to a novel candle-shaped filter which comprises a compound filter cylinder, a candle-shaped filter and a connecting nut, wherein, the candle-shaped filter is arranged at the central part of the compound filter cylinder; the connecting nut is arranged at the end part of the compound filter cylinder; a rubber sealed pad is arranged between the compound filter cylinder and the connecting nut; a filter screen is arranged between the compound filter cylinder and the candle-shaped filter element; and the filter screen is a metal fiber filter screen made of stainless steel. The filter has the advantages of good filter quality, long-time effective filtration, long replacement cycle of the filter, low using and manufacturing cost and long service life.

Description

A kind of novel candle filter

Technical field

The utility model relates to filter on a kind of short rayon fiber spinning machine, especially relates to a kind of novel candle filter on the short rayon fiber spinning machine.

Background technology

Candle filter is one of process conditions important on the short rayon fiber spinning machine.Its effect is, with before the spinning of accurate metering in the viscose glue impurity such as subsidiary inorganic, organic filler and rubber tackle by the filter material that is fixed on cartridge surface, to be transported to the clean qualified quick capacity of viscose glue then and enter spinning process in the composite spinning head, existing traditional candle filter is made of filter cylinder, filter core and coupling nut, its shortcoming is, filter material wherein adopts senior silk or nylon wire the earliest, though certain filter effect is arranged, tensile strength is low, filter quality is unstable; Secondly, filter cylinder, coupling nut and filter are stainless steel, corrosion easily, and service life is short.

In addition, a lot of enterprises are sought by increasing filter area, prolong effective filtration time (changing the filter cycle) and improve some problems that filtration exists before spinning.But owing to dismounting, the cleaning of candle filter must be manual operations, contour structure size is too big, and very heavy all being not easy to of weight operated.Therefore, the filter of metal material has been subjected to another kind of restriction again.

Summary of the invention

Its purpose of the utility model is to address the aforementioned drawbacks and provides a kind of filter quality good, and effective filtration time is long and the replacing filter cycle is long, use cost and low cost of manufacture, the novel candle filter of long service life.

The technical scheme that realizes above-mentioned purpose and take is: this filter is made of compound filter cylinder, candle filter and attaching nut, be provided with candle filter in the middle of the wherein compound filter cylinder, the end of compound filter cylinder is provided with the attaching nut, and be provided with rubber gasket between compound filter cylinder and the attaching nut, be provided with screen pack between compound filter cylinder and the candle filter core, screen pack is the stainless steel metal fibre filter screen.

Described compound filter cylinder is by the modification Reinforced Polypropylene and stainless steel is compound constitutes, and attaching nut 3 selects nylon material for use, and connecting thread is the stainless steel thread bush partly, and inlays in the into compound filter cylinder, and the viscose glue runner of cartridge surface is made as the circular arc screw thread.

Compared with prior art this device has the following advantages:

1, reduces one-time investment expense and permanent maintenance expense;

2, reduce spinning and change a viscose glue loss 50%; Reduce renew cartridge Shan glue loss 50%;

3, reduce labor strength, reduce cost of labor;

4, the metal fibre filter material is recyclable utilizes again, reduces the filter material cost of use.

5, filter quality is good, and effective filtration time is long and the replacing filter cycle is long, use cost and low cost of manufacture, the advantage of long service life.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described in further detail

Fig. 1 is the utility model structural representation.

The specific embodiment

Embodiment, as shown in Figure 1, this filter is made of compound filter cylinder 1, candle filter core 2 and attaching nut 3, be provided with candle filter core 2 in the middle of the wherein compound filter cylinder 1, the end of compound filter cylinder 1 is provided with attaching nut 3, and be provided with rubber gasket 4 between compound filter cylinder 1 and the attaching nut 3, be provided with screen pack 5 between compound filter cylinder 1 and the candle filter core 2, screen pack 5 is the stainless steel metal fibre filter screen.

Described compound filter cylinder 1 is by the modification Reinforced Polypropylene and stainless steel is compound constitutes, and attaching nut 3 is provided with nylon material, and connecting thread is the stainless steel thread bush partly, and inlays in the into compound filter cylinder 1, and the viscose glue runner on filter core 2 surfaces is made as the circular arc screw thread.

Workflow:

Viscose glue passes through P before the filter ₁Cavity pressure enters candle filter core P again through runner, the filter opening that filter screen enters cartridge surface ₂The chamber becomes filter back viscose glue by the attaching nut.Pressure P ₁Mainly be subjected to what of viscose glue measuring pump and surface of filter medium filter opening, P ₂The influence of length of size, filtration time.Pressure P ₂Mainly be subjected to composite spinning head chamber pressure, gooseneck and loss of filter core flowpath pressure and the influence of composite spinning head continuous spinning time.Therefore, desirable filter quality, the longest effective filtration time (it is the longest to change the filter cycle) be obtained, P must be reduced ₁The pressure P in chamber ₁And P ₂Cavity pressure P ₂From various analysis of Influential Factors, with regard to filter itself, increase effective filtration area, improve viscose glue runner (make it the pressure loss reduces as far as possible), selection intensity greatly, this three aspect of filter material not yielding, that filtering accuracy is stable starts with and just can obtain better filter effect.
