In the furnace equipment of invention, the top of described tunnel cave 201 is provided with fire brick layer 217, institute
State and on fire brick layer 217, be provided with Margarita rock stratum 218, the upper berth of described Margarita rock stratum 218
If concrete prefabricated board 219 (seeing Fig. 4).
Based on same consideration, in tunnel cave 201, the body of wall near kiln road is fire brick layer.
The both sides of tunnel cave 201 body of wall are additionally provided with reinforcing column, pass through between two edge columns
Connect cross bar to connect, prevent tunnel cave from firing and deform afterwards.
The present invention provide furnace equipment make fired brick method, comprise the steps: by
The temperature of tunnel cave 201 is heated to 700-1000 DEG C, adobe is sent in drying kiln 101,
The outlet of described drying kiln 101, the described tunnel of rear entrance is arrived from described drying kiln 101 entrance
In road kiln 201, arrive the outlet of described tunnel cave 201 from described tunnel cave 201 entrance,
Obtain fired brick.
Said method takes full advantage of the architectural characteristic of this furnace equipment, only need to be to tunnel cave
201 heat, and without drying kiln 101 is heated, it is ensured that the present invention provides
Method energy consumption low, simple and fast, and the intensity of the fired brick prepared is high.
Further, it is divided into preheating when described tunnel cave 201 along entrance to Way out
Section 211, high temperature section 212 and cooling section 213, described preheating section 211 and described cooling section
The body of wall of 213 is cavity wall 214 and solid wall 215 from top to bottom, described cavity wall 214
On be provided with air port 216, the ventilating duct connected with the air inlet of described centrifugal blower is with described
Inner space connection (see Fig. 4) of cavity wall 214；It is provided with thermoelectricity in described high temperature section 212
Even, when described thermocouple is connected with computer control system, described high temperature section 212 is along described
Tunnel cave 201 entrance to Way out be divided into first paragraph, second segment, the 3rd section and the 4th
Section, the temperature of described first paragraph is 700-900 DEG C, and the temperature of described second segment is
920-970 DEG C, the temperature of described 3rd section is 970-920 DEG C, and the temperature of described 4th section is
900-700℃。
The primary structure district that high temperature section 212 sinters as adobe, its temperature affects adobe and exists
The internal structure formed in sintering process, and then affect the intensity of finished bricks.The present invention provides
Method in high temperature section 212 is divided into four sections along tunnel cave entrance to Way out so that
The curved arrangement of temperature of high temperature section.By this method, it is ensured that the intensity of finished bricks is high.
Although illustrate and describing the present invention with specific embodiment, but it will be appreciated that
May be made that without departing from the spirit and scope of the present invention many other change and
Amendment.It is, therefore, intended that include in the following claims belonging in the scope of the invention
