Description

White carbon black ultrafine pulverization and iron removal device

1. Technical field

The utility model relates to a material crushing and iron removal device, in particular to a white carbon black ultrafine crushing and iron removal device.

2. Background technology

Precipitated silica is a widely used fine chemical product, mainly used in rubber, silicone rubber, plastics, coatings, inks, pesticides, papermaking, food, medicine, feed and other fields. The superfine white carbon black has higher added value. It is made by jet mill or mechanical mill ultrafine pulverization. Most of the mill materials are iron-containing alloys. During the pulverization process, iron-containing powder will be produced. If it is not cleaned, it will be destroyed. Directly into the product, resulting in a decline in product quality. At present, stainless steel lining corundum is mainly used as the inner cavity of the pulverizer to avoid iron powder pollution, but the equipment is expensive and the cost of producing powder is high.

3. Contents of the invention

The purpose of this utility model is to provide a white carbon black superfine grinding and iron removal device to solve the problem of pollution of white carbon black products by iron powder produced by mill wear during the superfine white carbon black crushing process.

In order to achieve the above purpose, the utility model white carbon black ultra-fine crushing iron removal device includes a flange, iron removal box and magnetic rods, and a plurality of magnetic rods are evenly installed on the box body, and the magnetic rods are connected with the box body by a spiral interface. The box body is connected to the outlet of the pulverizer in the front through the flange, and connected to the inlet of the single cyclone dust collector in the rear.

After continuous production using the above-mentioned structure of white carbon black ultra-fine pulverization and iron removal device, a large amount of black gray powder is attached to the magnetic rod, the whiteness of the product is improved, and the iron content is significantly reduced. The iron content drops from the original 220ppm to below 180ppm.

The above-mentioned white carbon black ultra-fine pulverization and iron removal device is simple to manufacture, low in cost, easy to operate, and conducive to popularization.

Fig. 1 is a schematic front view of the structure of the superfine grinding and iron removal device for white carbon black of the present invention.

Fig. 2 is a schematic plan view of the structure of the superfine grinding and iron removal device for white carbon black of the present invention.

Fig. 3 is a schematic diagram of the equipment layout of the ultra-fine pulverization and iron removal device for white carbon black of the present invention.

5. Specific implementation

In the following, the device for removing iron by superfine grinding of white carbon black of the present utility model will be further described in detail in conjunction with the accompanying drawings and specific embodiments.

As shown in Fig. 1 and Fig. 2, the white carbon black ultrafine pulverization iron removal device of the present utility model comprises flange 8-1, iron removal box body 8-2 and magnetic force rod 8-3, and iron removal box body 8-2 adopts stainless steel The material is designed in a flat cylindrical shape, and 7 stainless steel magnetic rods 8-3 are evenly installed on the box body 8-2 according to the figure, and are connected with the box body 8-2 by a spiral interface, and the stainless steel magnetic bars 8-3 are arranged in two rows Form three regular triangles, the diameter of the magnetic rod 8-3 is 35mm, the length is 300mm, and the magnetic field strength is 10000 Gauss. As shown in Fig. 3, the white carbon black ultra-fine crushing iron removal device of the present utility model is connected to the outlet of the pulverizer 7 in front and the inlet of the single cyclone dust collector 9 in the rear through the flange 8-1. In Figure 3, A is connected to the material feed pipe after drying, B is connected to the air outlet pipe of fan 2, and C is connected to the bag filter.

When working, the dried material is sent to the middle silo 3 of the mill by the fan 2, and the butterfly valve 4 is slowly opened, the material is put into the hopper of the mill, the power of the mill is turned on, and the speed of the grading wheel of the mill is adjusted to 500r/min, adjust the opening degree of the feed valve 6 of the pulverizer, so that the material can evenly enter the 7 grinding chamber of the pulverizer for ultra-fine pulverization. After the crushed material is iron removed by the iron remover 8, it passes through the single cyclone dust collector 9 and the double cyclone dust collector 11, and the material in the single cyclone dust collector 9 and the double cyclone dust collector 11 enters the finished product silo 12 through the first-stage shut-off fan 10 , and then enter the automatic packaging machine through the secondary fan 13 for packaging. The magnetic bar of the iron remover is manually cleaned every 8 hours.
