Problems solved by technology

The disadvantage is that the production capacity is low, the increase of the mixing process is easy to cause lead poisoning, and the wear of the abrasive tool is large, the production cost is high, and the probability of returning to the furnace for reburning due to the excessive iron content of the red lead product is increased, which affects the quality of the product , further increasing production costs

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 ...

Abstract

A water process energy-saving granulation technology for red lead production comprises the following steps: (1) dedusting cooling (pretreatment); (2) screw conveying; (3) re-conveying; (4) deironing; (5) granulator starting; (6) water process granulation; and (7) exhausting dedusting. The technology has the advantages of simple process, easiness in operation, realization of automatic streamline working of the production flow of red lead, increase of the production efficiency, energy saving, consumption reduction, and avoiding of occupational hazards; and iron in lead powder is removed to provide guaranteeing for the production of the high-quality red lead product.

Description

technical field [0001] The invention relates to the technical field of red lead processing, in particular to a water-based energy-saving granulation device for red lead production. Background technique [0002] At present, the production and granulation process of red lead is a production process after the lead ingot is melted and powdered. The traditional red lead production process does not require a granulation process, and the lead powder (lead oxide powder) obtained by melting the lead ingot is directly put into the red lead calcination oxidation furnace (horizontal oxidation furnace), at a high temperature of about 500 ℃ Red lead products were prepared by calcination and oxidation. This calcination oxidation method has low production efficiency and high energy consumption, because after the lead powder is piled up in the calcination furnace, the gap between them is small, the high temperature penetration is weakened, and the oxidation speed of the lead powder is delay...
