Formaldehyde purification device

Abstract

The invention discloses a formaldehyde purification device. The device comprises a shell, an air inlet formed in the shell, an air guide plate arranged below the air inlet, a water supply device arranged outside the shell, an ozone generator arranged on the shell, an ultraviolet generator arranged in the shell, a rotatable purification roller arranged in the shell, an adhesion ball is arranged onthe purification roller, a motor arranged outside the shell, a discharging box arranged above the purification roller, a cleaning brush arranged on the left side of the purification roller, an air outlet formed outside the shell, and an exhaust fan arranged on the air outlet. The discharging box comprises a left cavity, a right cavity, a plurality of storage boxes arranged in the right cavity, a plurality of discharging pipes arranged below the discharging boxes, a rotating pipe arranged on the discharging pipes and provided with an opening, a first inclined plate arranged below the discharging pipes, a ball arranged on the first inclined plate and a plurality of telescopic rods arranged below the first inclined plate. The inclined plate shakes due to the fact that the adhesion ball on thepurification roller collides with the telescopic rod, materials falling on the inclined plate are evenly mixed and then evenly smeared on the adhesion ball from the discharging mechanism, so that powder on the purification roller is more uniform, and therefore automatic smearing is achieved.

Description

Technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a formaldehyde purification device. Background technique [0002] The existing formaldehyde purification device first manually smeared ZSM-5 molecular sieve on the filter plate, and then smeared the composite photocatalyst composed of titanium dioxide, tungsten trioxide and lanthanum oxide with a mass ratio of 30:1:1 on the filter plate; Then the formaldehyde is absorbed by the filter plate, and the formaldehyde-absorbed filter plate is removed for cleaning; this way, the manual application is not uniform enough, and the filter plate needs to be disassembled and assembled; this affects the effect of formaldehyde purification. Summary of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides a formaldehyde purification device that can automatically uniformly spread ZSM-5 molecules and composite photocatalyst.
