Abstract

The utility model relates to a candlewick filter, particularly to a candlewick filter for a spinning machine, wherein a filter screen is a three-layer metal filter screen structure, including an inner layer supporting screen, a middle layer filtering screen and an outer layer protecting screen. A metal filter screen is employed instead of a filter cloth, thus avoiding the difficulty in filtering and smoothing the supply of a spinning nozzle. The filter screen employs the three-layer structure so as to permit a more stable structure, prevent entrance of the external dusts and impurities, prolong the service life and increase the filtering quality.

Description

The candle wick filter

Technical field

The utility model relates to a kind of candle wick filter, and more particularly, the utility model relates to a kind of candle wick filter that is used for spinning-drawing machine.

Background technology

At present the rayon spinning mode of production has two kinds of continuous spinning and direct methods.Spinning-drawing machine candle wick filter all is that plastic barrel twines fine cloth filtration viscose glue outward.

The principle of filtering is: viscose glue is transported to filter (filter cylinder) through measuring pump, after the outer surface filter cloth of candle wick filter filters, through candle wick filter interior passage viscose glue is transported to spinning head again, the filter cloth of spinning head filter once more eject by spinning head with acid bath groove in H ₂SO ₄React and generate the thick fiber of giving birth to.After the candle wick filter used some cycles, absorption a certain amount of impurity in filter cloth surface caused filtration difficulty, then will change filter cloth, and cleaning filter reuses.

The problem of above-mentioned candle wick filter is:

1, after the candle wick filter used certain hour, the filter cloth surface will be adsorbed quantitative impurity and be caused filtration difficulty, and spinning head viscose glue supply reduces, and produced blob of viscose or strand and attenuated;

2, the process labour intensity in dismounting and cleaning and winding is big and loaded down with trivial details;

3, the filter cloth life cycle is short, and fluctuation takes place the adhesive-preparing technology of viscose glue and maturation is filtered when breaking down, and filter cloth is breakdown easily, and it is a large amount of thick fine to cause spinning to occur, and damages spinning head when more serious;

4, the material of candle wick filter is a bakelite, weares and teares easily in its end thread coupling part, causes life cycle short, and expense increases, and be three months general service life;

5, the filter core life cycle is short, changes the core cycle to be approximately 2 days, and changing the core cycle during viscose quality fluctuation is 1 day;

6, the viscose glue waste is big, whenever changes 1 filter and will lose the 750ml viscose glue;

7, seriously polluted, bring bigger pressure to efforts at environmental protection.

The utility model content

The utility model is intended to solve existing candle wick filter and breaks down easily, and life cycle is short, and waste is big, and with serious pollution problem provides a kind of economic environmental protection, is difficult for breaking down the candle wick filter that can increase work efficiency.

To achieve these goals, concrete technical scheme of the present utility model is as follows:

The candle wick filter comprises skeleton, skeleton nut, connector and filter screen, and it is characterized in that: described filter screen is the three-layer metal filter structure, comprises internal layer supporting network, middle level screen pack and outer protecting wire net; Filter screen is fixed between skeleton and the skeleton nut, and the skeleton nut is threaded with connector.

Described middle level screen pack is that the braiding of layer 2-4 20 μ m wire nettings forms.

The useful technique effect that the utility model brings:

1, filter screen adopts three-decker, makes filter structure more firm, prevents that external dust, impurity from entering, and has prolonged service life, has improved filter quality;

2, owing to adopt metal filter screen, do not need filter cloth, can not produce the problem of filtration difficulty, and make the supply of spinning head more smooth and easy;

3, reduced greatly the dismounting, cleaning process labour intensity, saved the time, improved operating efficiency;

4, do not use filter cloth after, can not produce potential safety hazard, can not cause damage to spinning head yet, prolonged the service life of spinning head;

5, viscose glue and stainless corrosivity are very little, almost can ignore, and filter the filter quality that has improved viscose glue on the contrary because of the wire netting that uses 20 μ m.

Description of drawings

Figure of description is a cross-sectional view of the present utility model.

Reference numeral: 1 is that skeleton, 2 is that skeleton nut, 3 is that connector, 4 is filter screen.

The specific embodiment

Embodiment 1

The candle wick filter comprises skeleton 1, skeleton nut 2, connector 3 and filter screen 4, and described filter screen 4 is the three-layer metal filter structure, comprises internal layer supporting network, middle level screen pack and outer protecting wire net; Filter screen is fixed between skeleton and the skeleton nut, and the skeleton nut is threaded with connector.

In order to strengthen the filter capacity of filter, the middle level screen pack is that 2 layer of 20 μ m wire netting braiding forms.

Embodiment 2

In order to strengthen the filter capacity of filter, the middle level screen pack is that 4 layer of 20 μ m wire netting braiding forms.

Embodiment 3

In order to strengthen the filter capacity of filter, the middle level screen pack is that 3 layer of 20 μ m wire netting braiding forms.

Embodiment 4

Bakelite material and metal material compare:

?	The bakelite material	Metal material
			Change the core cycle	2-3 days	6-8 days
Service life
		3 months	3 years
The filter cloth operating position				Twine	3 metafiltration cloth	Need not use filter cloth
	The viscose glue waste	20364L/	9636L/

Embodiment 5

The comparison of structure of the present utility model and traditional structure processing quality:

Embodiment 6

One, economic benefit:

1, save filter cloth: on average changed 99 (two day one-period) in one day, and needed 99 cloth, a month 99*30*1.35=4009.50 unit saved 4009.5 yuan of * 12(of fuse cloth expense months in 1 year)=48114 yuan;

2, save viscose glue: change a filter core loss viscose glue 0.8L, 365 days=20364 liters of 99 * of 0.8 liter of * of annual accumulating losses, 1697 yuan/1000 liters=34557.7 yuan of 20364 liters of * of expense (pulp is by 1.3 ten thousand yuan/ton);

3, save filter core: adopt metal knitted net to change the core cycle and can reach 7 days, 5 years service life, 3 months service life of existing plastics filter core.So consumed 1056 plastics filter cores in 1 year.Expense: 80 yuan/root of 1056 *=84480 yuan.

To sum up, can reduce expenses the whole year: 48114 yuan+84480 yuan+34557.7 yuan=167151.7 yuan

Two, social benefit:

Change the core rate and can reduce by 70%, significantly reduce labor strength.

Can reduce by 2.0364 ten thousand liters of viscose glues every year, reduce environmental pollution.
