Embodiment

[0029] Referring to FIG. 1 , a device for making core materials of double-layer vacuum insulation panels described in this embodiment includes: a slurry tank 10 , a shunt pipe 20 , a headbox 30 , a forming wire 40 , and a pressure roller 50 . Among them, the area of ​​the hole at the bottom of the slurry tank is 10% of the bottom area, and the length of the shunt pipe is 1.5m.

[0030] When using this device to make the core material of double-layer vacuum insulation panels, the specific process steps are as follows:

[0031] (1) sending the glass fiber cotton slurry with a diluted concentration of 0.4% into the slurry storage tank;

[0032] (2) The slurry in the slurry storage tank is sent into two headboxes through the shunt pipe, and then the glass fiber cotton is dehydrated and formed by corresponding forming wires respectively to form a glass fiber cotton core material blank; in this step, the forming wire is When the glass fiber cotton is dehydrated, the speed of the fo...

Abstract

The invention discloses a device and a method for manufacturing double-layer vacuum heat-insulation plate cores. The device comprises a slurry proportioning pond, a distributing pipe, head boxes, forming nets and a press roll. The device and the method have the advantages that the vacuum heat-insulation plate core production efficiency can be doubled owing to an upper and lower laying mode, limited geographic spaces can be sufficiently utilized, and the investment cost can be saved; the device is directly modified by the aid of existing production technologies and is easy to manufacture, widely popularize and use on a large scale and convenient and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation material engineering, and in particular relates to a device for manufacturing a core material of a double-layer vacuum thermal insulation panel. Background technique [0002] Vacuum insulation panels are composed of filling core material and vacuum protection surface layer. It can effectively avoid heat transfer caused by air convection, so it has extremely low thermal conductivity, excellent thermal insulation performance and good environmental protection performance. It is currently the most advanced in the world. efficient thermal insulation material. Vacuum insulation panels are heat-insulating and environmentally friendly materials with excellent heat-insulating performance and no pollution in the process of manufacture, use and post-use treatment. They are widely used in low-temperature fields such as refrigerators, refrigerated trucks, and cold storage, as well as heat preservati...
