Embodiment 1
[0037] A water-based energy-saving granulation process for red lead production, the method steps are as follows:
[0038] (1) Dust removal and cooling (pretreatment)
[0039] The lead powder obtained by melting the lead ingot is transported to the bag filter through the pipeline under the action of the induced draft fan, and the dust is removed and the temperature is lowered to about 100°C. The initial temperature of the lead powder is about 380°C;
[0040] (2) Screw conveying
[0041] The first auger (screw conveyor) is installed in parallel at the bottom of the bag filter, and the first auger runs counterclockwise at a speed of 30 rpm. Under the action of the action, it is continuously transported to the discharge port of the first auger (direction is downward), and then from the discharge port to the auger in the granulation equipment;
[0042] (3) Re-delivery
[0043] A second auger is also installed under the first auger. The speed and direction of the second auger are...
Embodiment 2
[0053] see figure 1 , figure 2 :
[0054] A water-based energy-saving granulation device for red lead production, comprising: support 1, bag filter 2, discharge auger 3, discharge motor 4, feed auger 5, feed motor 6, tube barrel 7, granulation Barrel 8 and material storage box 9, the granulation tube 8 is installed on the bracket 1, the feeding auger 5 is installed in the tube tube 7, and one end extends to the granulation tube 8, but it is not connected with the granulation tube 8 and can work alone , the other end stretches out about 80 centimeters from the pipe 7, and there is a red lead feed port 10 at the upper end of the stretched part, and the tail is connected with the feed motor 6, and the feed motor 6 is responsible for the work of the feed auger 5 alone, and the feed auger 5 The blades in the center rotate counterclockwise and are responsible for transporting the raw materials entering the feed auger 5 to the granulation barrel 8 at a speed of 30 revolutions per ...
