Embodiment 1）

[0054] See figure 1 , 3 And 6, the thermal insulation device of the ceramic roller kiln in this embodiment is the thermal insulation device of the gas-fired open flame roller kiln, including kiln body thermal insulation parts and pipeline thermal insulation parts.

[0055] See image 3 , The kiln body heat preservation parts include a thermal insulation composite layer 500, a fixing part 701, a support bar 702, and an iron sheet 703. The thermal insulation composite layer 500 is composed of an aluminum silicate fiber blanket layer 501 and a first airgel thermal insulation blanket layer 502 .

[0056] The aluminum silicate fiber blanket layer 501 and the first airgel thermal insulation blanket layer 502 are laid sequentially from the inside to the outside to cover all the outer surfaces of the ceramic roller kiln kiln body where the thermal insulation layer 300 is installed, and the fixing member 701 is set Outside the first airgel thermal insulation blanket layer 502, the t...

Embodiment 2）

[0073] See Figure 4 and Figure 5 , the rest of this embodiment is the same as that of Embodiment 1, the difference is that: the kiln body insulation part of this embodiment also includes an insulation composite layer 600 . The thermal insulation composite layer 600 is divided into single thermal insulation composite layer 600a, double thermal insulation composite layer 600b and triple thermal insulation composite layer according to the number of glass fiber felt layers and airgel thermal insulation blanket layers included. The single thermal insulation composite layer 600a has only one composite layer, that is, the first glass fiber felt layer 601 and the second airgel thermal insulation blanket layer 602 are sequentially arranged from inside to outside. The double thermal insulation composite layer 600b has 2 composite layers, that is, the first glass fiber felt layer 601, the second airgel thermal insulation blanket layer 602, the second glass fiber felt layer 603 and the...

Embodiment 3）

[0082] The rest of this embodiment is the same as that of Embodiment 1, except that: the thermal insulation device of the ceramic roller kiln of this embodiment also includes a roller gap thermal insulation member.

[0083] The roller gap insulation part is made of hard airgel heat insulating material, and the shape of the roller gap insulation part matches the shape of the gap between the rollers, and is closely attached to the rollers. The rigid airgel thermal insulation material used in this embodiment is RunAG1000-10 type rigid airgel manufactured by Changzhou Xuntian Energy Saving Technology Co., Ltd.

[0084] The gap between the rollers in the prior art has serious heat dissipation, and is generally blocked with aluminum silicate loose cotton, and the aluminum silicate loose cotton is often burned and needs to be replaced once a month. And the roller gap insulation parts can keep using for about 1 year without failure.

Abstract

The invention discloses an attemperator for a ceramic roller kiln. The attemperator comprises a kiln thermal-insulation element and a pipe thermal-insulation element. The kiln thermal-insulation element comprises a thermal-insulation composite layer, a fixed part, a support bar and an iron sheet, wherein the thermal-insulation composite layer is composed of an alumina silicate fiber blanket layer and a first aerogel thermal-insulation blanket layer, and the support bar is fixed outside the first aerogel thermal-insulation blanket layer. The iron sheet is fixed on the outer side of the support bar, and an air layer is formed between the iron sheet and the first aerogel thermal-insulation blanket layer. The pipe thermal-insulation element comprises 1-3 groups of thermal-insulation composite layers, a fixed part, a support bar and an iron sheet, wherein thermal-insulation composite layers are composed of glass fiber mat layers and aerogel thermal-insulation blanket layers and are wrapped on peripheral surfaces of smoke pipes and warm-air pipes group by group; and the iron is wrapped on the outer side of the support bar, and an annular cavity is formed between the iron sheet and the outermost-layer aerogel thermal-insulation blanket. According to the attemperator, the secondary thermal-insulation effect to the roller kiln body is remarkable, and heat dissipation of the smoke pipes and the warm-air pipes are reduced substantially.

Description

technical field [0001] The invention relates to a thermal insulation device of an industrial kiln, in particular to a thermal insulation device of a building ceramic roller kiln. Background technique [0002] The ceramic industry is an important traditional industry in my country. Ceramic products mainly include architectural ceramics, daily-use ceramics, sanitary ceramics, and special ceramics. China's production of architectural ceramics, sanitary ceramics, daily-use ceramics, and artistic ceramics has ranked first in the world for many years in a row. Ceramic production consumes a lot of energy and resources. According to statistics, the production of wall and floor tiles, sanitary ware, daily-use porcelain and artistic porcelain in my country consumes about 34.4 million tons of standard coal and 124 million tons of raw materials every year. At the same time, it also produces a large amount of exhaust gases and residues. The huge consumption of energy and resources and t...
