Problems solved by technology

However, because most of the current hot-pressing and shaping equipment is formed by heating and pressing the upper and lower molds, limited by the size of the mold, the glass wool needs to be cut and then hot-pressed off-line, which cannot achieve continuous online operation; in addition, the heating is not uniform in the thickness direction. Affects its thermal insulation performance
This has resulted in discontinuous dry process operations, a lot of labor, poor controllability, low efficiency, high cost, and it is difficult for practical production and application

Embodiment 1

[0033] refer to figure 1 , an on-line dry-process glass wool vacuum insulation board core material production system in this embodiment includes a furnace 1, a centrifuge 2, a cotton collector 3, a hot-press setting device 4 and a transmission device 5. Furnace 1 is used to melt raw materials to form molten glass; centrifuge 2 is used to spin molten glass into glass fibers; cotton collector 3 is arranged under the centrifuge to collect glass fibers to form glass wool; hot pressing device 4 and The cotton collector 3 is connected by a conveying device 5 for hot-pressing glass wool to form a glass wool felt; the conveying device 5 can be known conveying equipment such as a conveyor belt or a conveyor chain.

[0034] refer to figure 2 , The thermocompression setting device 4 includes a chamber 41, a transfer pressing system 42 and a heating system (not shown). One end of the chamber 41 close to the cotton collector 3 is provided with a material inlet 411 , the other end is pro...

Embodiment 2

[0043] refer to Figure 5 , an on-line dry-process glass wool vacuum insulation board core material production system in this embodiment includes a melting furnace (omitted in the figure), a centrifuge 2, a cotton collector 3, a hot-press setting device 4', a transmission device 5, Curing furnace 6 and cooling transfer end 7. The settings and functions of the melting furnace, the centrifuge 2 and the cotton collector 3 are the same as in Embodiment 1, and will not be repeated here. The curing furnace 6 is set between the cotton collector 3 and the hot-press setting device 4' and is connected by the conveying device 5 for drying and heating the glass wool, and the hot-press setting device 4' is used for hot-pressing the glass heated by the curing furnace 6 cotton to form a glass wool felt, and the glass wool felt is cooled and sent out by the cooling transmission end 7.

[0044] The hot-press setting device 4' is roughly the same structure as the hot-press setting device 4, a...

Abstract

The invention discloses an online dry method glass wool vacuum insulated panel core material production system. The system comprises a smelting furnace, a centrifuge, a wool collector and a hot-press shaping device. According to the hot-press shaping device, an upper chain plate and a lower chain plate are matched to form a press-fit interval, glass wool is pressed in the press-fit interval, and continuous hot-pressing can be carried out in the transmission process. The invention further provides a production method based on the production system. Compared with the prior art, online continuous production is achieved, production efficiency is high, and a manufactured glass wool core material is simple in structure and good in heat insulating effect.

Description

technical field [0001] The invention relates to a production system and method for an on-line dry-process glass wool vacuum insulation board core material. Background technique [0002] Vacuum insulation panel is a new type of high-efficiency thermal insulation material that combines the principle of vacuum insulation with traditional thermal insulation materials. It is composed of membrane materials, core materials and getter materials. The gas is removed through internal vacuum treatment, thereby eliminating The heat transfer path is isolated from heat conduction, so as to achieve the purpose of heat preservation, heat insulation and energy saving. Vacuum insulation panels are widely used in refrigerators, incubators, building walls, refrigerated containers and other fields. [0003] The core material is the core of the vacuum insulation panel, and it is mostly made of materials with high porosity, connected pores and low thermal conductivity, such as glass wool felt. It...
