A high-quality and high-capacity melt-blown material production equipment and process

Abstract

The invention discloses a high-quality and high-capacity melt-blown material production equipment and process, which belongs to the technical field of non-woven special material production. It includes a mixer, and a mixing partition is arranged in the mixer to separate the mixer into two parts. , a double-layer stirring device is arranged in the front space of the mixer; a twin-screw extruder is connected behind the mixer, and a delivery pump is connected to the twin-screw extruder to send the degradation agent into the twin-screw extruder, and the extruder The extruder head is connected to the cooling device, and the bottom plate and side wall of the cooling box are equipped with a cooling device; the material cooled by the cooling device is transported to the pelletizer by the conveyor belt for pelletizing, and the pelletized material is sent to After being blown dry by a fan, it is sent into a homogenizing blending tank through a rotary feeder for homogenization processing, and then sent into a finished product tank. The present invention further optimizes the process steps, carries out integrated and intensive design and layout, completes a substantial upgrade of production efficiency, and satisfies the increasing demand for orders.

Description

technical field [0001] The invention relates to the technical field of production of special materials for non-woven fabrics, in particular to a production equipment and process for high-quality and high-capacity melt-blown materials. Background technique [0002] The production process of melt-blown nonwovens (melt-blown non-woven fabrics) is a civil industrial technology developed by ExxonMobil in the United States in the 1960s on the basis of the air-jet spinning method researched by the US Naval Laboratory, and then melt-blown The patent license for the production of nonwovens technology is granted to several companies. Melt-blown non-woven materials are widely used in medical protection, sanitary cleaning materials, filter materials, thermal wadding materials, oil-absorbing materials, battery separators and other fields because of their excellent barrier filtration, air permeability, oil absorption, thermal insulation and sound insulation properties, and It has heat an...

Problems solved by technology

With the unremitting efforts of independent research and development and innovation, the quality of domestic materials is gradually improving and has been more and more recognized by the market. The domestic excellent production technology is also being continuously optimized and improved. For example, the Chinese patent No. CN201510023201.8 has been published A production method and production equipment for polypropylene melt-blown non-woven special materials, which solve the problem of unstable melt index and wide molecular weight distribution in the production process of the existing technology, which is not suitable for the melt-blown spinning process; and the die head and water tank Inappropriate design, difficult molding and other problems, the non-woven fabric produced by the above process is soft to the touch, has good air permeability, excellent filterability, and no peculiar smell, and has been recognized by downstream customers

However, 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 product quality, and the cooling efficiency of water cooling is low. It also consumes water resources and increases the volume of equipment. Therefore, it is necessary to propose further optimized processes and improved designs to solve the problems encountered in production and meet the ever-increasing demand.
