preparation example Construction

[0055] A preparation method of a thin gel fiber product of the present invention comprises the following steps:

[0056] S1: Adjust the height of the feed roller 19 relative to the belt knife 9 through the thickness adjustment component;

[0057] Specifically, screw the nut 12, and the nut 12 drives the adjusting rod body to rotate, so as to adjust the depth of the threaded section 18 at the lower part of the adjusting rod body in the threaded hole 22, so that the distance between the adjusting rod body ring platform 25 and the upper surface of the fixing block 16 becomes larger Or the rear end of the adjusting rod 11 is supported on the ring table 25 under the action of gravity, so that the distance between the feeding roller 19 and the belt knife 9 is increased or decreased.

[0058] S2: transfer the gel felt 4 to the knife edge of the belt knife 9, and press the gel felt 4 under the feed roller 19, and the belt knife 9 cuts the gel felt into the upper thin gel felt 13 and t...

Embodiment 1

[0073] The preparation method of the thin ceramic fiber gel felt with a thickness of 1mm is as follows:

[0074] S1: Adjust the height of the feed roller 19 relative to the belt knife 9 to 1mm through the thickness adjustment component;

[0075] S2: The 2mm thick ceramic fiber felt is impregnated with the sol and then gelled, and after immersed in the sol, it is conveyed and gelled on the conveyor belt 3 to obtain the ceramic fiber gel felt. The ceramic fiber gel felt is transferred to the knife edge of the belt knife 9, and the ceramic fiber gel felt is pressed under the feeding roller 19. The belt knife 9 cuts the gel felt into an upper thin gel felt 13 and a lower thin gel felt. 14;

[0076] S3: the upper thin gel felt 13 and the lower thin gel felt 14 are separated by the receiving mechanism;

[0077] S4: The upper thin gel felt 13 and the lower thin gel felt 14 are respectively wound up.

[0078] The thicknesses of the obtained upper thin gel felt 13 and lower thin gel...

Embodiment 2

[0080] The preparation method of the thin glass fiber gel felt with a thickness of 0.2mm is as follows:

[0081] S1: Adjust the height of the feed roller 19 relative to the belt knife 9 to 0.2mm through the thickness adjustment component;

[0082] S2: the 2mm thick glass fiber mat is impregnated with the sol and then gelled, and then conveyed and gelled on the conveyor belt 3 after impregnating the sol to obtain the glass fiber gel mat. The glass fiber gel felt is transferred to the knife edge of the belt knife 9, and the glass fiber gel felt is pressed under the feeding roller 19. The belt knife 9 cuts the gel felt into 0.2mm thick upper thin gel felts 13 and 1.8 mm thick lower thin gel felt 14;

[0083] S3: The upper thin glass fiber gel felt and the lower thin glass fiber gel felt are separated by the receiving mechanism;

[0084] S4: Rewind the upper thin glass fiber gel felt and the lower thin glass fiber gel felt respectively. The lower thin glass fiber gel felt is al...

Abstract

The invention relates to thin gel fiber product production equipment. The thin gel fiber product production equipment comprises a rack, a belt cutter mechanism and a driving structure, wherein the belt cutter mechanism comprises a first belt wheel, a second belt wheel, a belt cutter wound on the first belt wheel and the second belt wheel; the first belt wheel and the second belt wheel are rotationally arranged on the rack at an interval front and back; the belt cutter is rotationally arranged between the first belt wheel and the second belt wheel in the front-back direction. The feeding mechanism comprises a thickness adjusting assembly and a feeding roller which are arranged on the rack; the feeding roller is arranged above the knife edge of the band knife; the thickness adjusting assembly can adjust the distance between the feeding roller and the band knife. The receiving mechanism is arranged on the rack and located at the discharging end of the band knife, and the receiving mechanism separates the two sectioned thin gel felts so that the two sectioned thin gel felts can be wound respectively; for the gel felt with the same thickness, the thin gel felt formed by sectioning the thick gel felt has higher gel content, so that the thinner gel felt has better heat insulation performance.

Description

technical field [0001] The invention belongs to the technical field of gel felt preparation, and in particular relates to thin gel fiber products, production equipment and a preparation method thereof. Background technique [0002] Aerogel refers to a solid structure that does not collapse after the liquid in the gel structure is replaced by gas. Silica aerogel is a continuous three-dimensional network structure formed by the polymerization of nano-scale particles. Because of its special nano-scale micropore and skeleton structure, its thermal conductivity, convective heat transfer efficiency and radiation heat transfer efficiency are improved. are effectively confined, so the aerogel has a very low thermal conductivity. [0003] Aerogel felt is a composite product obtained by first impregnating fiber material with sol, then forming a gel felt, and finally drying it. After forming a gel felt, you can choose whether to perform aging, hydrophobic modification, solvent replace...
