Abstract
The application provides a long-term type filter bag melt-blown filter material, combine to constitute including first filter portion and second filter portion, first filter portion be the non-woven fabrics layer, the second filter portion is formed by holding the cotton layer of dirt and melt-blown cotton layer stromatolite complex, is the corrugate through folding, holds the cotton layer of dirt outside, is fixed in first filter portion and constitutes. The technical scheme greatly increases the specific surface area and the dust holding capacity of the filter material, and has the technical advantages of high dust holding capacity, low wind resistance and high filtering efficiency.
Description
Technical Field
The present patent application relates to air filtration materials, and more particularly to filtration materials for air filter bags.
Background
In the industries of automobiles, electronics, precision instruments and the like, air conditioning units of factory buildings are all provided with air filters using melt-blown cotton filter bags. The conventional structure of the filtering material of the current melt-blown cotton filter bag air filter comprises dust holding cotton, a melt-blown cotton layer and a non-woven fabric laminated layer, and an ultrasonic welding edge sealing, wherein the dust holding cotton is used for separating large-particle dust, the melt-blown cotton is used for filtering fine particles, the dust holding cotton and the melt-blown cotton are combined in a graded filtering manner, the high filtering precision of the product is ensured, and the cost is low. From the function of each layer of the filter material, the melt-blown cotton has no capability of containing dust, when the dust-containing cotton is saturated, a large amount of dust invades the melt-blown cotton, the melt-blown cotton is rapidly blocked and loses efficacy, the air resistance of a filtering system is increased, the air volume is reduced, the whole filter material is in a working state with low filtering efficiency and high energy consumption, and compared with a polyester fiber filter bag filter material product, the filter material has a short service cycle and needs to be frequently replaced. The technical problem of short service life of the filter material of the melt-blown cotton filter bag is solved, the key point is to solve the actual condition of low dust holding capacity of the filter material of the melt-blown cotton filter bag, but the dust holding capacity is difficult to realize under the condition that the product size standard is strictly limited simply by increasing the thickness of the dust holding cotton.
Disclosure of Invention
The invention aims to prolong the service life of a filter bag filter material and provide a long-acting type filter bag melt-blown filter material based on the standard size of the current melt-blown cotton filter bag air filter product.
The application provides a long-term type filter bag melt-blown filter material technical scheme, its main technical content is: the long-acting filter bag melt-blown filter material comprises a first filter part and a second filter part, wherein the first filter part is a non-woven fabric layer, the second filter part is formed by laminating and compounding a dust containing cotton layer and a melt-blown cotton layer, the second filter part is folded to be corrugated and fixed on the first filter part, and the dust containing cotton layer is an outer layer.
In a preferable mode of the above scheme, the dust-containing cotton layer and the melt-blown cotton layer of the second filter part are compounded by glue spraying.
In a preferred embodiment of the present invention, the folding edge on the meltblown cotton layer side of the second filter portion is fixed to the first filter portion.
In a preferable mode of the above aspect, the second filter portion has a corrugation width of 3 to 5 mm.
The utility model discloses a long-term type filter bag melts and spouts filter media technical scheme, the second filter portion of ripple fold structure has increased by a wide margin filtering material, especially hold the cotton specific surface area and the dust holding capacity of dirt under the prerequisite that does not change whole size and dimension, has played its high dust holding capacity, low windage, the high technological advantage of straining the effect in practical application, and its life cycle reaches 1.5 times of conventional product structure.

Detailed Description
The long-acting filter bag melt-blown filter material disclosed by the application is an important component of a melt-blown cotton filter bag air filter, and is widely applied to air filtration of workshop workshops in industries such as automobiles, electronics and precision instruments. The long-acting filter bag melt-blown filter material is formed by combining a first filter part A and a second filter part B as shown in the attached drawing.
The first filter part A is a non-woven fabric layer,
the second filter part B is formed by laminating and compounding a dust containing cotton layer 1 and a melt-blown cotton layer 2. In order to ensure that the dust-containing cotton layer 1 and the melt-blown cotton layer 2 are firmly compounded and do not separate, the two opposite compound surfaces are compounded by spraying glue and bonding and fixing glue wires.
The second filter part B is folded and expanded into a corrugated shape, and the amplitude of the corrugation is preferably 3-5 m.
The second filter part B is provided with a dust-containing cotton layer 1 outside and a melt-blown cotton layer 2 inside, and the outer folding edges 12 of the melt-blown cotton layer 2 are fixed on one side surface of the first filter part A to form the long-acting filter bag melt-blown filter material.
