Kiln car kiln tool for firing foam ceramics

Abstract

The invention relates to a kiln car kiln tool for firing foam ceramics. The kiln car kiln tool for firing foam ceramics comprises a kiln car; stand columns are arranged on the kiln car; layer holes are formed in the stand columns; main beams are erected on the layer holes; auxiliary beams are arranged on each layer of the main beam; supporting plates are laid on all the auxiliary beams; each supporting plate is erected on every two auxiliary beams; all the supporting plates form a supporting plate layer; the supporting plate layer comprises a middle supporting plate, edge supporting plates andangle supporting plates; edge baffles are arranged above the edge supporting plates and the angle supporting plates; each edge baffle comprises a vertical panel and supporting plates arranged on theback face of the vertical panel; positioning devices are arranged between the edge supporting plates, the angle supporting plates and the edge baffles; the positioning device consist of baffle positioning ribs arranged on the edge supporting plates and the angle supporting plates and positioning clamping grooves arranged on the lower end face of the supporting plates; and the baffle positioning ribs and the positioning clamping grooves are in assembly movable fit. The requirement for firing the foam ceramics can be met, the boundary of a product is standard and tidy, the ratio of the product to the kiln tool is high, the energy is saved, the consumption is reduced, and the mechanization and automation of production can be realized.

Description

technical field [0001] The invention relates to a kiln car and kiln furniture for firing foam ceramics. Background technique [0002] At present, the kiln car kiln furniture used for firing foam ceramics is mainly composed of a kiln car and a single-layer or multi-layer frame composed of a column on the kiln car, a main beam on the column, and an auxiliary beam on the main beam. structure; then set up the trough on the frame structure of each layer, the trough is mainly composed of a bottom plate composed of multiple fire-resistant plates and a positioning device surrounded by multiple baffles. In the process of firing foam ceramics, the material will foam and expand. Therefore, the material in the trough must not only expand upward, but also expand to the surroundings. During the process, the foamed ceramic material will cause the displacement of the peripheral baffle, resulting in the change of the originally set boundary. When processing the foamed ceramic slab, it is ne...

Problems solved by technology

[0003] In the existing kiln car and kiln furniture for firing foam ceramics, in order to overcome the displacement of the surrounding baffles or reduce the displacement, the main methods are: (1) Chinese patent 205156604 discloses a new type of kiln for firing foam ceramics The peripheral baffle is made into a triangular baffle, and the weight of the triangular baffle is increased to increase the friction with the bottom plate to reduce the displacement. The disadvantage is that the material ratio of the kiln furniture is large and the energy consumption is large; (2) China Patent 208671653 discloses a roller kiln car for the production of foamed ceramics. The peripheral baffles are made into four surrounding components, and the two ends of the components are respectively provided with tenon and tenon holes for connection; (3) China Patent 204177208 discloses a foamed ceramic plate kiln car, which adopts a combined bottom plate and baffle plate, and sets a through hole on each bottom plate and fixes the baffle plate with a positioning pin to prevent its displacement

In the second and third methods, although the baffles can be fixed very well, the boundary of the fired ceramic slab is more regular and the utilization rate is higher; but its disadvantage is that manual operation is required , cannot be operated by manipulators, and cannot meet the needs of automated production
