Glass fiber needled felt silicon-based nano aerogel powder spraying and collecting device

Abstract

A glass fiber needled felt silicon-based nano aerogel powder spraying and collecting device comprises a powder spraying device and a powder collecting device, the left side of a powder spraying pipe of the powder spraying device is communicated with a powder conveying pipe, the powder conveying pipe is communicated with a powder spraying fan, a powder inlet is formed in a shell body, wrapping an impeller, of the powder spraying fan, the powder inlet is communicated with a powder inlet pipe, and the powder inlet pipe is communicated with a horizontal left pipe of a three-way pipe; a control valve is arranged between the powder inlet pipe and the three-way pipe, a horizontal right pipe of the three-way pipe is communicated with the air inlet valve and the air inlet pipe, a branch pipe of the three-way pipe is communicated with the bottom of the powder storage tank, and a powder spraying hole array is arranged at the bottom of the powder spraying pipe; a negative-pressure dust suction groove is formed under the powder spraying pipe, a powder suction hole array is formed in the upper end face, right facing the powder spraying pipe, of the negative-pressure dust suction groove, the right end of the negative-pressure dust suction groove is communicated with an air inlet of a powder collecting fan shell, an air outlet of the powder collecting fan shell is communicated with a second powder conveying pipe, the second powder conveying pipe is communicated with a powder collecting distribution pipe, and all branches of the powder collecting distribution pipe are communicated with powder collecting filter bags respectively. The powder collecting filter bag collects nano aerosol powder and allows filtered air to pass through.

Description

technical field [0001] The invention relates to the technical field of powder spraying and powder collection of glass fiber needled felt, in particular to a device for spraying glass fiber needled felt and recovering silicon-based nano aerogel powder. Background technique [0002] Glass fiber needled felt is a sheet-like product made of continuous strands or chopped strands that are non-directionally bound together by chemical binders or mechanical action. Glass fiber needled felt has a certain thermal insulation effect, but there are There is no good solution to the disadvantages of low thermal insulation efficiency and large heat loss. Therefore, we propose a glass fiber needle-punched felt thermal insulation gel spraying recovery device system. SUMMARY OF THE INVENTION [0003] The present invention mainly solves the technical problems existing in the above-mentioned prior art, and provides a powder spraying and collecting device system for the glass fiber needle-punche...
