工作原理:在使用该催化剂生产用烘干机时,首先需对整个催化剂生产用烘干机有一个结构上的了解,在使用时,能够更加便捷的进行使用,将入料口6和出水管18分别与相应的管道连接,将该装置接通电源,此时PLC控制器16启用电机5、加热器9、加热灯11、传送带13、电磁阀20,催化剂经过入料口6进入到搅拌室8的内部,此时电机5带动搅拌刀7转动,同时电机带动空气泵1工作,空气经入气管17进入空气泵1,空气在空气泵1的作用下进入第一容器2,此时第一容器2与第二容器4之间的溢流阀起到保压作用,使第一容器2内的空气压力远远大于大气压力,此时空气中的水析出到筛板3上,筛板3上析出的水存储到水箱15中,从溢流阀溢出的空气进入第二容器4,此时进入第二容器4的空气恢复大气压力致使空气温度下降,从而空气中的水进一步的析出到筛板3上,析出到筛板3上的水存储到水箱15中,此时较为干燥的空气进入搅拌室8内,干燥的空气与催化剂充分搅拌,在搅拌过程中加热器9对搅拌室8加热使催化剂中的水分挥发到空气中,此时催化剂与空气经过出料管10落到传送带13的顶面,处于传送带顶侧的催化剂经传送带13输送到挡板14的下方,同时输送过程中催化剂经加加热灯11的加热进一步的挥发催化剂中含有的水分,从而实现烘干。Working principle: When using the dryer for catalyst production, you first need to have a structural understanding of the entire dryer for catalyst production. When in use, it can be used more conveniently. The inlet 6 and the outlet pipe 18 are respectively connected with the corresponding pipelines, and the device is powered on. At this time, the PLC controller 16 enables the motor 5, the heater 9, the heating lamp 11, the conveyor belt 13, and the solenoid valve 20, and the catalyst enters the mixing chamber through the feed port 6. 8, at this time, the motor 5 drives the stirring knife 7 to rotate, and at the same time, the motor drives the air pump 1 to work, the air enters the air pump 1 through the air inlet pipe 17, and the air enters the first container 2 under the action of the air pump 1. The overflow valve between the container 2 and the second container 4 plays a role of maintaining pressure, so that the air pressure in the first container 2 is far greater than the atmospheric pressure. The water precipitated on the top is stored in the water tank 15, and the air overflowing from the overflow valve enters the second container 4. At this time, the air entering the second container 4 restores the atmospheric pressure and causes the air temperature to drop, so that the water in the air is further precipitated into the sieve. On the plate 3, the water precipitated on the sieve plate 3 is stored in the water tank 15. At this time, the relatively dry air enters the stirring chamber 8, and the dry air and the catalyst are fully stirred. During the stirring process, the heater 9 heats the stirring chamber 8. The moisture in the catalyst is volatilized into the air. At this time, the catalyst and air fall to the top surface of the conveyor belt 13 through the discharge pipe 10, and the catalyst on the top side of the conveyor belt is transported to the bottom of the baffle plate 14 through the conveyor belt 13. At the same time, the catalyst is The moisture contained in the catalyst is further volatilized by heating with the heating lamp 11, thereby realizing drying.
