Example Embodiment

[0030] Example 1

[0031] like image 3 As shown, it is a schematic diagram of the structure of the preparation device of the composite melt-blown filter element material. The preparation device of the composite melt-blown filter element material includes a traditional melt-blown device and a feather fiber feeding device, and the traditional melt-blown device includes a screw extruder. The discharge machine 4 and the filter element receive the winding device 5. The feather fiber feeding device includes a round pipe 6, an air compressor and a ZBG011 type cotton feeding weighing machine. The upper nozzle of the round pipe 6 is connected to the ZBG011 through a horn-shaped joint. The outlet of the type feeding and weighing machine is connected, the compressed air outlet of the air compressor is connected with the outlet of the ZBG011 feeding and weighing machine, and the compressed air generated by the air compressor enters from the outlet of the feeding and weighing machine. Th...

[0032] Example 2

[0033] like figure 2 As shown, it is a flow chart of the preparation method of the composite melt-blown filter element material, and the specific steps of the preparation method of the composite melt-blown filter element material are:

[0034](1) The low-density polyethylene resin chips with the grade of 888-000 produced by China Petrochemical Corporation are heated and extruded into a molten state by the screw extruder 4, filtered by a filter and metered by a metering pump, and then enter the spinneret hole. After the spinneret holes are extruded, they reach the filter element receiving and winding device 5 under hot air drafting, and are then cooled to form the core layer 1 of the composite filter element material. Specific process parameters: the temperature of the screw extruder 4 is 220°C, the number of spinneret holes of the screw extruder 4 is 600, the extrusion rate of each die head spinneret hole is 0.3g / min, the drawing hot air The temperature i...

Abstract

The invention provides a composite melt-blown filter core material filled with feather fiber, and a preparation device and method thereof. The composite melt-blown filter core material filled with the feather fiber is characterized by comprising a core layer, a middle layer and a surface layer, wherein the middle layer is placed in the middle; the core layer and the surface layer are respectively composited on the two surfaces of the middle layer; the core layer is provided with melt-blown fiber; the middle layer is a composite layer provided with the feather fiber and melt-blown fiber; and the surface layer is provided with melt-blown fiber. According to the composite melt-blown filter core material, the feather fiber and polypropylene fiber are bonded together through a melt-blown technology, so a feather non-woven material is formed, the defect that the feather fiber is difficult to process is overcome and the filling amount of the feather fiber is increased.

Description

technical field [0001] The invention belongs to the field of composite nonwoven material and its preparation, more specifically, the invention relates to a nonwoven composite filter material filled with feather fiber and its preparation device and method. Background technique [0002] my country is a big country in the production and trade of down, feathers and their products, rich in down and feather resources, with an annual output of more than 600,000 tons, and has formed a market size of 30 billion yuan, accounting for 60% of the world's total output. At present, except that 20% of down quilts are used as thermal filling materials, only 3% to 5% of the remaining 80% feather resources have been utilized, mainly used as filling materials, shuttlecocks and handicrafts, and a few are used to extract protein as fertilizer. The research and development of feathers and their products at home and abroad are still at the level of rough processing of raw materials. The total utili...
