ROLLER KILN DEVICE AND PRODUCTION SYSTEM COMPRISING THE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/031772
Kind Code:
A1
Abstract:
Disclosed in the present invention are a roller kiln device and a production system comprising the device. The solution comprises a kiln furnace, a kiln furniture, a burner and a slow cooling fan unit; the kiln furnace comprises a smoke discharging section, a firing section and a cooling section, the length of the cooling section being less than the sum of the length of the smoke discharging section and the length of the firing section; the cooling section comprises a rapid cooling section, a front slow cooling section, a double-layer rear slow cooling section and a double-layer fast cooling section which are sequentially provided; a hoister is provided between the front slow cooling section and the rear slow cooling section; the slow cooling fan unit is provided on the front slow cooling section and the rear slow cooling section, the burner is at least located on the firing section, and a product outputted from the front slow cooling section is delivered by means of the hoister to the double-layer rear slow cooling section for cooling, so that the rear slow cooling section and the fast cooling section can achieve twice the product cooling efficiency. By changing the length distribution of the smoke discharging section, the firing section and the cooling section, the time control of smoke discharging, firing and cooling is realized, the overall length of the kiln furnace is shortened, and the circulating cooling of hot air is realized by means of the slow cooling exhaust fan, thereby achieving the recycling of energy.
