High-load low-resistance melt-blown material production device and method

Abstract

The invention discloses a high-load low-resistance melt-blown material production device and method. The high-load low-resistance melt-blown material production device comprises a hopper, and a feeding device is movably arranged at the side end of the hopper; a mixing partition plate is arranged in a mixing machine to divide the mixing machine into a front space and a rear space, a double-layer stirring device is arranged in the front space of the mixing machine, and stirred and mixed materials enter the rear space of the mixing machine through a first discharging hole below the mixing partition plate for temporary storage. A double-screw extruder, a cooling device and a cooling device are arranged at the tail end of the mixing machine; the materials cooled by the cooling device are conveyed to a granulator through a conveying belt for granulation and screening, the materials are dried by a fan and then fed into a homogenizing and mixing tank through a rotary feeder for homogenizing processing, and finally a finished product is prepared. The process steps are optimized, integrated and intensive design and arrangement are carried out, the production formula is unique, the productionresistance is reduced, discharging is smooth, the product quality is kept excellent, and high-load low-resistance melt-blown materials can be efficiently produced with high quality.

Description

technical field [0001] The invention belongs to the application field of melt-blown materials, in particular to a production equipment and method for melt-blown materials with high load and low resistance. Background technique [0002] Melt-blown cloth uses polypropylene as the main raw material, and the fiber diameter can reach 1-5 microns. These ultra-fine fibers with unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the melt-blown cloth has good filterability, Shielding, heat insulation and oil absorption, it can be used in air and liquid filter materials, isolation materials, absorption materials, mask materials, thermal insulation materials and wiping cloths and other fields. [0003] The production process of melt-blown nonwovens (melt-blown non-woven fabrics) is a civil industrial technology developed by the American Exxon Mobil Company in the 1960s on the basis of the air-jet spinning method researched by the US Naval ...

AI Technical Summary

Problems solved by technology

There is no perfect production process and equipment. In the process of use, we found that with the increase of market demand, the production efficiency of the existing technology still needs to be improved. The uneven mixing of the mixer affects the quality of the product. The quality of spraying material is not high, so it needs to be improved
