Problems solved by technology

[0009] In order to solve the problem of high energy consumption and high production cost of the traditional flame blowing method, and at the same time the technical difficulty of the high thermal conductivity of the heat shield caused by the uneven unraveling of raw cotton, the present invention proposes an integrated centrifugal blowing and beating method. Ultra-fine thermal insulation cotton production device, the equipment can not only realize the centrifugal blowing method to draw ultra-fine glass fiber cotton of 4 μm or less by softening and mechanically dispersing the centrifugal fiber, but more importantly, effectively solve the fiber flocculation caused by the traditional process Non-uniform fiber disentanglement caused by winding

Embodiment 1

[0054] (1) The ratio of raw materials is shown in Table 1.

[0055] Table 1. Example 1 Raw material ratio

[0056]

[0057] The above glass raw materials are sent to the mixer through each bin with a screw conveyor according to their respective component ratios for mixing, and the fully mixed and uniform proportioning material is transported to the front bin of the kiln via a belt conveyor.

[0058] (2) Furnace melting and homogenization

[0059] The proportioning material is put into the kiln by the automatic feeder. After the proportioning material enters the furnace, it will go through various high temperature stages of 810℃~1100℃, 1100℃~1300℃, and 1300℃~1390℃. From the solid granular raw materials through the sintering reaction, they will finally melt into a transparent glass.

[0060] (3) Forehearth cooling

[0061] After clarification, the molten glass will be cooled down to 1075°C from the initial approximately 1250°C after cooling in each forehearth area, reaching the primary fo...

Abstract

The invention belongs to the technical field of glass fiber cotton preparation, and relates to a production device and a production method of centrifugal blowing and pulping integrated superfine glassfiber cotton. The production device comprises a softening blowing cavity, a defibering cavity and a buffering cavity which are sequentially arranged from top to bottom, as well as a power system fordriving and controlling equipment in the cavities, and an instrument device for automatic control. By utilizing the device, the centrifugal blowing and pulping integrated production method of the superfine glass fiber cotton is realized. By means of the production device, through centrifugal fiber softening and mechanical defibering, superfine glass fiber cotton of 4 microns or below can be drawnthrough a centrifugal blowing method, and more importantly, the problem that fiber defibering is not uniform due to fiber flocculation and winding caused by a traditional process is effectively solved.

Description

Technical field [0001] The invention belongs to the technical field of glass fiber cotton preparation, and relates to a production device and a production method of ultrafine glass fiber cotton integrated with centrifugal injection, blowing and beating. Background technique [0002] The production of ultra-fine glass fiber cotton mainly uses glass clinker as raw material and is produced by flame injection technology. Ultra-fine glass fiber cotton has lower thermal conductivity and smaller bulk density than industrial insulation glass fiber cotton. However, due to the high energy consumption and high production cost of ultra-fine glass wool, it is mainly used in low-temperature refrigeration, biomedicine, precision manufacturing and aerospace fields. . [0003] In the existing technologies and processes, the injection drawing of fiber raw cotton and the beating and shaping of fiber cotton are carried out independently in the production space. Raw cotton production mainly involves ...
