Foamed ceramic plate kiln car

Abstract

The invention discloses a foamed ceramic plate kiln car. The foamed ceramic plate kiln car comprises a car body, wherein the car body is provided with a bottom layer, a stand column layer and a plate layer from bottom to top; the stand column layer is composed of a plurality of fireproof material stand columns and a plurality of supporting beams; the lower ends of the fireproof material stand columns are fixed above the bottom layer and are symmetrical with the central line of the car body; one supporting beam is arranged at the tops of every two fireproof material stand columns; the plate layer is located right above the supporting beams; the plate layer comprises a bottom plate and a plurality of positioning baffles arranged on the outer side above the bottom plate; the plurality of positioning baffles are arrayed in sequence to form one circle; at least two through holes are formed in the bottom plate on the outer side of each positioning baffle; and positioning bolts are arranged in the through holes. According to the foamed ceramic plate kiln car disclosed by the invention, fired foamed ceramic has the characteristics of uniform shape and specification, high boundary utilization rate and few waste materials.

Description

technical field [0001] The invention relates to a kiln car, more specifically, to a foamed ceramic board kiln car. Background technique [0002] At present, most of the kiln cars used in domestic traditional tunnel kilns are car-lined structures. The bottom part of the traditional kiln car is built with ordinary refractory bricks, and the middle part is made of shaped heat-insulating refractory materials. A number of refractory material columns are symmetrically arranged on the upper part of the shaped heat-insulation refractory material, and multiple support beams are arranged on the refractory material column. To support the bottom plate on which the firing materials are placed, a plurality of positioning baffles are placed on the outside of the bottom plate to encircle the city one by one to standardize the boundary of the foamed ceramic blank. The traditional kiln car starts the foaming process after placing the prepared foamed ceramic material within the position surro...

AI Technical Summary

Problems solved by technology

Usually, after the foamed ceramic material is placed in the position surrounded by the positioning baffle, the foamed ceramic material begins to foam and expand slowly, and when the local shape of the foamed ceramic material changes, it will exert a force on the positioning baffle, making it The position shifted, resulting in the change of the originally set boundary. When processing the foamed ceramic slab, it is necessary to cut and cut the surrounding boundary, wasting a certain amount of material
