Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic fiber blanket production, in particular to a multi-layer extrusion device for ceramic fiber blanket. Background Art

[0002] Ceramic fiber blanket, also known as aluminum silicate fiber blanket, aluminum silicate double-sided needle-punched blanket or aluminum silicate needle-punched blanket, is an external thermal insulation material. Ceramic fiber blanket has good thermal insulation effect and its own thermal conductivity is very low, only 0.22w / mk at 1000 degrees, which can effectively reduce temperature conduction and loss.

[0003] For example, Chinese patent publication number CN214214825U discloses a multi-layer extrusion device for a ceramic fiber blanket, comprising a base, two sets of receiving roller support columns vertically mounted on the top wall of the base, a set of bearings embedded in the wall of each of the two sets of receiving roller support columns away from each other, a rotating shaft disposed on the inner wall of each of the two sets of bearings, a receiving roller disposed between the two sets of rotating shafts, two sets of extrusion roller support columns vertically mounted on the top wall of the base, and a motor disposed above the front wall of the front extrusion roller support column. In the present utility model, the multi-layer extrusion device for a ceramic fiber blanket can extrude the ceramic fiber blanket by contact between the rubber roller and the base. Since the rubber roller is elastic, it deforms when in contact with the base across the ceramic fiber blanket, thereby increasing the contact area between the rubber roller and the ceramic fiber blanket, thereby increasing the extrusion effect.

[0004] The above patent has the following problems:

[0005] This patent has several drawbacks. For example, the ceramic fiber blanket may shift during extrusion, requiring constant readjustment, which wastes time. Furthermore, the extrusion rollers of the device can become severely worn after prolonged use and require replacement, which is inconvenient. Therefore, we propose a multi-layer extrusion device for ceramic fiber blankets. Utility Model Content
