Abstract
The invention discloses a kiln used for firing foaming ceramic. The kiln comprises a kiln body; a combustor is arranged in the kiln body, and burner ports are formed in the lower portion of the kiln body and communicated with one side wall of the combustor; the combustor is separated into two cavities, the upper cavity and the lower cavity are separated through a heat conducting ceramic plate, air holes are formed in the ceramic plate uniformly, and a hot-gas ejecting outlet is formed in the side wall of the lower cavity; the top of the kiln body is of a double-layer structure with an inner roof and an outer roof, the inner roof is of a circular arc-shaped structure, the inner roof and the kiln body are formed into a hanging type structure, and ladder blocks are arranged at the upper end of the kiln body; a round of top band is arranged on the edge of the inner roof, a layer of sealing gasket is arranged on the top band which is hung on the ladder blocks, and the height of the ladder blocks is three to four times of the thickness of the top band; the outer roof covers the inner roof, and the interval between the outer roof and the inner roof is 10-20 cm; the outer roof is fixedly connected with the upper end of the kiln body in a sealed mode and provided with a high-temperature flue gas outlet, a high-temperature flue gas outlet pipeline is connected with the hot-gas ejecting outlet. The kiln used for firing the foaming ceramic is safe, explosion resistant and low in energy consumption, and thermal energy can be recycled.
Description
Technical field
The present invention relates to flame-proof thermal insulation material field, particularly relating to the tunnel kiln for firing foamed ceramic.
Background technology
The tunnel kiln energy consumption of prior art is higher, and heat energy is discharged cannot effectively be recycled by flue gas, haves much room for improvement.
Chinese patent 201420029421.2, disclose a kind of Recuperative heat type formed coke tunnel kiln stove, comprise kiln body and combustion chamber, combustion chamber is positioned at kiln body clinkering zone inwall both sides, crown is the double-decker be made up of Nei Ding and outer top, interior top is evenly provided with passage, and kiln pushes up outward and is provided with volatile matter outlet port; The bottom of kiln body is provided with the nozzles be communicated with combustion chamber one sidewall, and another sidewall of combustion chamber is provided with hot gas entrance; The kiln car pad brick be arranged on bottom kiln body is double-edged fine-toothed comb structural configuration; Top, combustion chamber is also provided with the waste gas outlet port that kiln external body is communicated with.This technical scheme achieves the recycling of high temperature hot gas, but its combustion chamber combustion temperature is due to the heat extraction of the air-vent on kiln top, very high kiln temperature cannot be realized, need when needing higher temperature to increase energy consumption, if but seal completely and the accidents such as high temperature blast can be caused, be further improved.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of safety anti-explosive, energy consumption is low, can realize the kiln for firing foamed ceramic of heat energy recycling.
For realizing the object of the invention, provide following technical scheme: a kind of kiln for firing foamed ceramic, comprise kiln body, combustion chamber is provided with in described kiln body, kiln body bottom is provided with nozzles and is communicated with combustion chamber one sidewall, described combustion chamber is separated into two chambers, described upper and lower chamber is separated by thermal conductive ceramic plate, described ceramic wafer evenly offers air-vent, described lower chambers sidewall offers hot gas ejiction opening, it is characterized in that described kiln body top is inside and outside top double-decker, described interior top is arc-shaped structure, Nei Ding and kiln body are suspension type structure, kiln body upper end offers ladder shelves, interior top edge is provided with a circle rim, described rim is provided with one deck sealing gasket, described rim is mounted on ladder shelves, described ladder shelves height is 3 ~ 4 times of rim thickness, described outer overhead guard is on interior top, and Nei Ding interval 10 ~ 20cm, described Wai Ding and the upper end fixed seal connection of kiln body, described outer top is provided with high-temperature flue gas outlet, described high-temperature flue gas outlet pipeline connects hot gas ejiction opening.
As preferably, described ladder shelves inner surface is coated with one deck wearing layer.
As preferably, rim is circular arc, and surface is coated with wearing layer.
Beneficial effect of the present invention: the present invention by double-deck kiln top is set and in withstand on pressure large time can realize automatically open and close, substantially increase kiln in-furnace temperature and effectively prevent blast, greatly reduce energy consumption, realize heat energy recycling.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
