The both sides of 201 wall of tunnel oven are additionally provided with reinforcing column, are connected, are prevented by connecting cross bar between two edge columns
Tunnel oven deforms after firing.
The method that furnace equipment provided by the invention makes fired brick, includes the following steps：The temperature of tunnel oven 201 is added
Adobe is sent into drying kiln 101 to 700-1000 DEG C, going out for the drying kiln 101 is reached from 101 entrance of the drying kiln by heat
Mouthful, enter in the tunnel oven 201 afterwards, the outlet of the tunnel oven 201 is reached to get sintering from 201 entrance of the tunnel oven
Brick.
The above method takes full advantage of the architectural characteristic of the furnace equipment, need to only be heated to tunnel oven 201, without
Drying kiln 101 is heated, ensure that low energy consumption for method provided by the invention, it is simple and fast, and fired brick obtained is strong
Degree is high.
Further, when the tunnel oven 201 is divided into preheating section 211,212 and of high temperature section along entrance to export direction
The wall of cooling section 213, the preheating section 211 and the cooling section 213 is cavity wall 214 and solid wall 215, institute from top to bottom
It states and is provided with air port 216 on cavity wall 214, the ventilating duct being connected to the air inlet of the centrifugal blower and the cavity wall 214
Inner space connection (see Fig. 4)；Thermocouple is equipped in the high temperature section 212, the thermocouple connects with computer control system
When connecing, the high temperature section 212 is divided into first segment, second segment, third section and along 201 entrance of the tunnel oven to export direction
Four sections, the temperature of the first segment is 700-900 DEG C, and the temperature of the second segment is 920-970 DEG C, the temperature of the third section
It it is 970-920 DEG C, the 4th section of the temperature is 900-700 DEG C.
The primary structure area that high temperature section 212 is sintered as adobe, temperature affect what adobe was formed in sintering process
Internal structure, and then influence the intensity of finished bricks.By high temperature section 212 along tunnel oven entrance to outlet in method provided by the invention
Direction is divided into four sections so that the arc-shaped arrangement of temperature of high temperature section.By this method, ensure that the intensity of finished bricks is high.
Although illustrate and describing the present invention with specific embodiment, it will be appreciated that without departing substantially from the present invention's
Many other change and modification can be made in the case of spirit and scope.It is, therefore, intended that in the following claims
Including belonging to all such changes and modifications in the scope of the invention.
