Abstract
The utility model relates to a dust processor which is used to clean blackboard dust. A semi-closed pipeline is installed around a blackboard and is connected with an exhaust fan, a dissolution chamber and a sewer pipe in turn, the exhaust fan is started, a flowing air field is formed on the surface of the blackboard, and the dust which is generated due to cleaning the blackboard is sucked into the dissolution chamber and is discharged through the sewer pipe after physical treatment.
Description
Technical field
The utility model relates to a kind of device of removing the blackboard dust.
Background technology
At present, school generally uses the chalk writing content of courses, when removing letter written with chalk, certainly leads to many dust, and these dust are easy to by harm in people's suction body healthy, is suspended in the air then contaminated air.Most of schools do not address this problem, and some schools use non-dusting free ink pen to substitute chalk, avoid producing dust, but this method are wasteful relatively, neither directly remove the method for dust simultaneously.
Summary of the invention
The problem that the dust that produces when erasing the board in order to solve is sucked by human body, the utility model provide a kind of device of handling dust that absorbs, and the dust that produces when erasing the board can be sucked away rapidly, drain from downcomer after treatment, avoid being sucked by human body.
The technical scheme that its technical problem that solves the utility model adopts is: the pipeline of construction opening around blackboard, be equipped with slip lid control throughput and adjust dust suction position on the pipeline tapping.Pipeline is connected with several exhaust fans are closed, running by exhaust fan, form a mobile gas field on the blackboard surface, the dust that produces that erases the board is inhaled into pipeline with air-flow, dust enters the dissolving chamber by exhaust fan, the shower nozzle at dissolving top, chamber sprays fog dissolving dust, and dust solution flows into sewer along downcomer drains, and reaches the purpose of removing dust.
The beneficial effects of the utility model are, can remove the dust that erases the board and produce rapidly, clean air, and atmosphere is not polluted, only the pipeline made from common exhaust fan and common material is simple in structure, the materials saving.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a fundamental diagram of the present utility model.

Fig. 3 is the pipeline tapping front view
1. blackboards among Fig. 1,2,3,2. pipeline, 3. exhaust fan, 4. wall, 5. dissolving chamber, 6. shower nozzle, 7. slip lid, 8. pipeline tapping
The specific embodiment
Pipeline in Fig. 1 (2) is close to around blackboard (1) edge, pipeline (2) is connected with exhaust fan (3), wherein exceeding blackboard (1) marginal portion connects for sealing, arrow is represented dust and airflow direction, pipeline tapping (8) is towards blackboard, exhaust fan (3) and shower nozzle (6) are opened simultaneously, and dust enters and dissolves chamber (5) and promptly mix with water with water and flow away.In Fig. 3, slip lid (7) is along about the pipeline tapping (8) or slide up and down and can control the position that throughput and dust enter pipeline.
Claims (3)
1. a blackboard dust treater is linked in sequence by semi-enclosed pipeline and exhaust fan, dissolving chamber, and it is characterized in that: pipe ring is around the blackboard edge, and pipeline exit is installed exhaust fan, and the dissolving chamber is installed in place, exhaust fan gas outlet.
2. blackboard dust treater according to claim 1, cross-section of pipeline are the opening polygon, and pipeline tapping is towards blackboard, and aperture position, big I are by the slip lid adjustment.
3. blackboard dust treater according to claim 1, shower nozzle is installed at dissolving top, chamber, and shower nozzle is connected with the water source.
