Problems solved by technology

The existing bag filter has the following technical problems during use. First, the outlet at the bottom is open. At this time, because of the pressure difference between the inside and outside of the dust collector, the outside air will enter the dust collector from the outlet. Second, by adjusting the air volume in the existing cyclone separator, solid particles in a certain particle size range can be divided, but th

Embodiment 1

[0050] Such as figure 1 As shown, embodiment 1 provides a kind of preparation method of soft composite silica powder, and preparation method comprises the following steps:

[0051] Step 1. Add the mixture of glass sand, quartz sand and zircon sand to dilute acid, soak and boil for 20 minutes, filter, wash and dry with warm air; melt ceramics and sodium silicate at 1350°C for 4 hours to prepare a molten solid, and cool to room temperature for later use;

[0052] Step 2. Put the glass sand, quartz sand, zircon sand and molten solid obtained in step 1 into a pulverizer and crush them into particles with a particle size of 0-1mm. The specific operation is to mix the glass sand, quartz sand and zircon sand After the first crushing, a particle mixture with a particle size of 50-100mm is obtained; the particle mixture with a particle size of 50-100mm is sent to a grinder to grind particles with a particle size of 0-5mm; particles with a particle size of 0-5mm The third grinding to ...

Abstract

The invention provides soft composite silica powder which is prepared from the following components in parts by mass: 25-30 parts of glass sand, 15-20 parts of quartz sand, 10-15 parts of zircon sand, 12-18 parts of ceramic and 5-10 parts of sodium silicate. The preparation method of the soft composite silica powder is characterized by comprising the following steps: adding a mixture of glass sand, quartz sand and zircon sand into dilute acid, soaking and boiling for 20-30 minutes, filtering, washing, and drying with warm air; melting ceramic and sodium silicate at 1350-1400 DEG C for 4-5 hours to prepare a molten solid, and cooling to the room temperature for later use.

Description

technical field [0001] The invention belongs to the technical field of silicon micropowder, in particular to a preparation method of soft composite silicon micropowder. Background technique [0002] Silica powder is a widely used inorganic chemical material. In the preparation process of silica powder, bag filter is needed to classify the powder according to particle size. The existing bag filter has the following technical problems during use. First, the outlet at the bottom is open. At this time, because of the pressure difference between the inside and outside of the dust collector, the outside air will enter the dust collector from the outlet. The second is that the existing cyclone separator can divide the solid particles in a certain particle size range by adjusting the air volume, but the powder that is taken away with the airflow during the use of the existing bag filter It is usually collected and stored through the storage cabin, and the storage cabin is far away...
