The to-be-solved technical problem of the utility model is: overcome prior art's not enough, provide a novel gypsum cooling device, the cooling effect is more excellent, and the seal is good, and is clean and tidy clean, has greatly reduced transport dust and loading dust, and is energy-concerving and environment-protective.
The utility model discloses an adopt following technical scheme to realize:
novel gypsum cooling device, the reaction kiln is connected with shell and tube cooling cylinder feed inlet through arranging sediment screw conveyer and feed tube chain conveyer, shell and tube cooling cylinder discharge gate is connected with the gypsum feed bin through discharge tube chain conveyer, gypsum feed bin bottom discharge gate below is equipped with the dustless machine in bulk of intelligence, dustless machine in bulk of intelligence discharge gate department is equipped with the suction hood, the suction hood is connected with cyclone, cyclone is connected with the sack cleaner in proper order, one-level scrubbing tower, second grade scrubbing tower, the caustic wash tower, fan and aiutage are connected.
The shell and tube cooling roller is sealed and cooled, has good sealing property, and does not overflow dust and water vapor.
The top of the gypsum bin is provided with a bin top dust remover, and the bin top dust remover is connected with a cyclone dust remover.
And a discharge port at the bottom of the gypsum bin is provided with a pneumatic discharge valve and a feeder.
Dust baffles and dust curtains are arranged around the dust hood, so that dust is further reduced.
The working principle and the process are as follows:
hot gypsum gets into in feed pipe chain conveyer delivers to shell and tube cooling drum from reacting kiln through arranging sediment screw conveyer, let in the circulating water and cool down, low temperature gypsum after the cooling delivers to the gypsum feed bin through ejection of compact pipe chain conveyer and keeps in, open the even unloading of dustless installation of intelligence during the loading, the negative pressure that produces is pumped air through the tail gas fan to a small amount of dust of production through the suction hood, through cyclone, the sack cleaner, deliver to one-level scrubbing tower, second grade scrubbing tower, the caustic wash tower, tail gas is up to standard after the washing discharges through the aiutage.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model discloses use shell and tube cooler drum, the circulating water carries out forced circulation, and the material cools down with the indirect contact of circulating water, and the cooling effect is excellent, and the material can be followed 200 ℃ and dropped to 30 ℃, and shell and tube cooler drum seal is good, and no dust, vapor spill over, and on-the-spot clean and tidy is clean, and the circulating water use amount is few. Meanwhile, the conveying equipment uses a pipe chain conveyor, the conveying equipment is fully closed, and the loading system adopts an intelligent dust-free bulk loader, so that conveying dust and loading dust are greatly reduced.
