Embodiment Construction

[0024] refer to Figure 1-7 , a pencil lead dust collection device, including a dust flow pipe 1 for circulating pencil lead dust, wherein the air flow containing pencil lead dust will pass through the dust flow pipe 1, and then a spiral coil connected to the energization is provided at the bottom of the dust flow pipe 1 The closed door linked by the pipe 11, when the electric solenoid 11 starts to be energized, the closed door is closed, so that the two ends of the dust gas in the dust circulation pipe 1 are respectively blocked by the closed door and the movable top plate 2, which is used to block the dust flow in the air. Flow in the dust flow pipe 1 is convenient to provide a closed environment for cleaning the graphite in the pencil lead dust.

[0025] The top of the dust circulation pipe 1 is symmetrically provided with a movable top plate 2 for blocking the flow of dust. It should be noted that the movable top plate 2 is slidably connected with the top of the dust circu...

Abstract

The invention discloses a pencil lead dust collection device, which comprises a dust circulation pipe for circulating the pencil lead dust, the top of the dust circulation pipe is symmetrically provided with a movable top plate for blocking the flow of dust, and the bottom of the movable top plate is provided with a useful For the metal rod that absorbs graphite dust, the metal rod generates static electricity for absorbing graphite dust on the surface of the metal rod through an electrostatic generator, and the sliding sleeve on the metal rod is provided with a sliding cylinder for scraping the graphite on the surface of the metal rod. The symmetrical inner walls of the dust circulation pipes are provided with movable grooves for sliding. The present invention uses a metal rod to generate static electricity for absorbing graphite dust on the surface of the metal rod through an electrostatic generator, so that the metal rod with static electricity will adsorb graphite on the surface of the metal rod, thereby achieving the effect of collecting graphite and avoiding dust flying. problem, and then scrape off the graphite dust on the metal rod under the action of the scraper arc.

Description

technical field [0001] The invention relates to the technical field of dust collection, in particular to a pencil core dust collection device. Background technique [0002] At present, it is necessary to effectively cut the pencil lead during the production of school tools, which is convenient for users to use, but a large amount of pencil lead dust generated during the production and processing of the pencil lead will be scattered in the air, which requires Timely cleaning and collection of these pencil lead dust floating in the air is carried out in time, but the existing dust treatment often has the following problems: [0003] Existing dust cleaning technology is often not suitable for collecting graphite-containing pencil lead dust. The main reason for this is that pencil lead dust is composed of a large amount of graphite, which has good electrical conductivity, and the particles scattered in the air Pencil lead powder tends to cause short circuits in electrical circu...
