Problems solved by technology

[0002] During the calcination process, the interior of the calcination furnace is in a state of negative pressure, and the fuel and combustion air used for combustion in the furnace are sucked in by negative pressure. The amount of suction and the speed of flow are also determined by the negative pressure. If the internal negative pressure is too large, the material in the calciner will be sucked into the electric vacuum cleaner to continue to circulate. Repeated calcination will lead to a decrease in the quality of the raw materials for frying. If the negative pressure in the calciner is too small, there will be material spraying, which can be seen , the control of the negative pressure in the calcination furnace is an extremely important link in the calcination process

Abstract

The invention provides a method and device for controlling negative pressure in calcining furnace, and calcining furnace.The method comprises the steps that a pressure value at an outlet of the calcining furnace is collected; the opening degree of an outlet gate plate of the calcining furnace is adjusted according to the pressure value so as to adjust a negative pressure value in the calcining furnace to a preset negative pressure threshold. According to the method, the negative pressure in the calcining furnace can be adjusted to the suitable negative pressure threshold in real time, materialspraying is avoided, and meanwhile the calcination quality is improved.

Description

technical field [0001] The present application relates to the technical field of gypsum board production equipment, in particular to a method and device for controlling negative pressure in a calciner and a calciner. Background technique [0002] During the calcination process, the interior of the calcination furnace is in a state of negative pressure, and the fuel and combustion-supporting air used for combustion in the furnace are sucked in by negative pressure, and the amount of suction and the speed of the flow are also determined by the negative pressure. If the internal negative pressure is too large, the material in the calciner will be sucked into the electric vacuum cleaner to continue to circulate. Repeated calcination will lead to a decrease in the quality of the raw materials for frying. However, if the negative pressure in the calciner is too small, there will be material spraying, which can be seen , the control of the negative pressure in the calciner is an ex...
