FIG. 1 is a schematic illustration of a corrosion-resistant fumed silica cyclone;
in the figure: 1. gas material export, 2, material import, 3, unloading funnel, 4, compressed air import, 5, unloading pipeline.
Detailed Description
The utility model will be further explained with reference to the drawings.
As shown in fig. 1, the anticorrosive fumed silica cyclone separator comprises a gas material outlet 1, a material inlet 2, a discharging funnel 3, a compressed air inlet 4 and a discharging pipeline 5, wherein the lower end of the material outlet 1 is connected with the upper part of the discharging funnel 3, waste gas is discharged from the material outlet, the material inlet 2 is fixedly installed on the side edge of the upper part of the discharging funnel 3, raw materials enter the discharging funnel 3 from the material outlet, the lower end of the discharging funnel 3 is fixedly connected with the discharging pipeline 5, produced powder is discharged from the discharging equipment, the surface of the upper part of the discharging pipeline 5 is connected with the compressed air inlet 4, and the inside attached white carbon black is blown out of the discharging equipment by the aid of the compressed air, so that the white carbon black and acidic gas are prevented from corroding the discharging pipeline 5, and the inner wall of the discharging pipeline 5 is provided with a ceramic attached layer, and the corrosion resistance of the discharging pipeline 5 is further enhanced.
In order to ensure that the cyclone separation effect is better, the side edge of the upper part of the blanking funnel 3 is fixedly provided with a material inlet 2 along the tangential direction.
In order to further enhance the cyclone effect, the upper surfaces of the blanking funnel 3 and the material inlet 2 are flush.
In order to ensure that the interior of the discharging funnel 3 is not corroded, the inner side of the discharging funnel 3 is provided with a ceramic attached layer
When in use, the anticorrosive fumed silica cyclone separator is installed and connected with corresponding pipeline equipment, and then the device can be put into use.
Has the advantages that: the ceramic coatings are added on the inner side surfaces of the blanking funnel 3 and the blanking pipeline 5, so that the corrosion resistance of the blanking funnel 3 and the blanking pipeline 5 can be effectively improved; through compressed air inlet 4 to the inside highly-compressed air that provides of unloading pipeline 5, can clear away the white carbon black that adds unloading funnel 3 and 5 inside surface adhesions of unloading pipeline, prevent effectively that inside from being corroded to stop to lead to the influence that the shut down appears because of equipment corrodes, can guarantee the separator steady operation effectively.
