With the needs of ceramic production, generation after generation of ceramic craftsmen constantly summarized, improved and innovated according to the firing experience, so that the kiln technology has been continuously developed and evolved. As one of the types of kiln, the kiln furnace cavity placed in the kiln frame of the arch tunnel kiln includes kiln wall, arch top and kiln base; the arch top is fixed on the kiln base through the kiln wall; the kiln wall includes arch corner brick group, heat preservation group (including heat preservation brick group and multiple layers of heat preservation cotton board outside the heat preservation brick group), temperature resistant brick group, roller hole brick, the heat preservation group is placed outside the temperature resistant brick group, and the specific structure is shown in Figure 6 The structure of the kiln wall has the following shortcomings:

[0004] 2) The arch corner brick group includes outer arch corner brick and inner arch corner brick, and the heat preservation brick group and the temperature resistant brick group in the heat preservation group below the inner arch corner brick are flush; after long-term use of the kiln, the kiln wall subsides, the gap between the inner arch corner brick and the heat preservation brick group and the temperature resistant brick group expands, and occasionally the flame from the gap will flow to the heat preservation cotton board, thereby burning the heat preservation cotton board.
[0005] 3) If the roller bar for conveying ceramics breaks in the high temperature area of the kiln, the kiln flame will flow from the roller hole brick to the heat preservation cotton board during the process of replacing the roller bar, thereby burning the heat preservation cotton board. SUMMARY

[0020] Further, the heat preservation brick group further comprises a third heat preservation brick.
[0021] The third heat preservation brick is arranged above the roll hole brick group.
[0022] The third heat preservation brick is arranged above the roll hole brick group.
[0023] The heat preservation plate is arranged below the heat preservation cotton board and cooperates with the third heat preservation brick to form a curved sealing structure between the passage corresponding to the roll hole brick of the roll hole brick group and the heat preservation cotton board.
[0024] The heat preservation plate is arranged below the heat preservation cotton board and cooperates with the third heat preservation brick to form a curved sealing structure between the passage corresponding to the roll hole brick of the roll hole brick group and the heat preservation cotton board.

In addition, the temperature-resistant brick group cooperates with the inner arch corner brick to form a curved sealing structure, which can effectively prevent the flame from flowing from the inner arch corner brick to the heat preservation cotton plate through the gap between the heat preservation brick group and the temperature-resistant brick group due to long time and kiln wall sinking, so that the heat preservation cotton plate is not burned.
[0036] 2.

Detailed Implementation
[0048] The present invention will be further described below with reference to specific embodiments:
[0049] like Figures 1 to 5 As shown, the high-insulation kiln wall structure described in this embodiment includes an arched brick group, an insulation group, a heat-resistant brick group, a roller-hole brick group 12, a heat-resistant board 10, and a cotton support board 11; the insulation group is placed outside the heat-resistant brick group; the roller-hole brick group 12 is placed below the heat-resistant brick group; the insulation group includes an insulation brick group 1 and a multi-layer insulation cotton board 2 located outside the insulation brick group 1.
[0050] Specifically, in the embodiment, the arch corner brick set comprises an inner arch corner brick 3 abutting the bottom of the arch top and an outer arch corner brick 4 arranged outside the inner arch corner brick 3; the bottom of the inner arch corner brick 3 is provided with a first curved sealing groove; one of the corners of the outer arch corner brick 4 is provided with a receiving groove, and nano sealing material 5 is poured into each receiving groove, and the nano sealing material 5 is specifically nano alumina.
[0051] Specifically, in the embodiment, the temperature-resistant brick set comprises a first temperature-resistant brick 6, a second temperature-resistant brick 7, a third temperature-resistant brick 8 and a fourth temperature-resistant brick 9.
[0052] The second temperature-resistant brick 7 is arranged below the inner arch corner brick 3, the end of the first temperature-resistant brick 6 is clamped into the first curved sealing groove, the side of the first temperature-resistant brick 6 is opposite to the gap between the inner arch corner brick 3 and the second temperature-resistant brick 7, and the bottom of the first temperature-resistant brick 6 is flush with the bottom of the second temperature-resistant brick 7.
[0053] The side of the outer arch corner brick 4 is opposite to the gap between the inner arch corner brick 3 and the first temperature-resistant brick 6.
[0054] The third temperature-resistant brick 8 is arranged above the roll hole brick set 12, and the outer side end bottom of the third temperature-resistant brick 8 is provided with a second curved sealing groove; the temperature-resistant plate 10 is arranged below the thermal insulation cotton board 2, the end of the temperature-resistant plate 10 is clamped into the second curved sealing groove, and a curved sealing structure is formed between the channel corresponding to the roll hole brick of the roll hole brick set 12 and the thermal insulation cotton board 2.
[0055] The cotton board 11 is arranged below the temperature-resistant plate 10 and used for supporting the temperature-resistant plate 10.
[0056] The fourth temperature-resistant brick 9 and the thermal insulation brick set 1 are both arranged between the first temperature-resistant brick 6 and the second temperature-resistant brick 7 and the third temperature-resistant brick 8; the thermal insulation brick set 1 is arranged outside the fourth temperature-resistant brick 9.
[0057] Specifically, in the embodiment, the temperature-resistant plate 10 is a ceramic fiber zirconium-containing plate and has high temperature resistance.
[0058] The first temperature-resistant brick 6, the second temperature-resistant brick 7, the third temperature-resistant brick 8 and the fourth temperature-resistant brick 9 are all mullite bricks and also have high temperature resistance.
[0059] In the above, the materials of each layer of the thermal insulation cotton board 2 are different.
[0060] The working principle of the embodiment is as follows:
[0061] The nano sealing material 5 is poured into the receiving groove of the outer arch corner brick 4, and after multiple outer arch corner bricks 4 in the same row are tightly installed, the multiple nano sealing materials 5 arranged inside form two “thermal insulation defense lines” (as shown in FIG. 6), so as to improve the thermal insulation performance of the joint between the arch corner brick set and the kiln frame and slow down the rate of heat loss in the ceramic kiln as much as possible.

[0065] The temperature-resistant plate 10 and the temperature-resistant brick group are both made of high-temperature-resistant materials, which can improve the performance and service life of the ceramic kiln.
[0066] Although the fourth temperature-resistant brick 9 is more temperature-resistant relative to the heat insulation brick group 1, the strength thereof is relatively low, and the strength of the kiln wall body can be greatly improved by additionally arranging the heat insulation brick group 1 on the outer side of the fourth temperature-resistant brick 9.
[0067] The above-mentioned embodiments are only the preferred embodiments of the present application, and do not limit the implementation range of the present application, so that any change made according to the shape and principle of the present application should be covered in the protection range of the present application.
