Abstract
The utility model discloses a kind of environment-friendly dustless blackboard eraser, include 7 font handle type housings, be provided with and whitewash in the horizontal component left end of housing, outside whitewashing, be covered with telescopic cover, mesh plate and negative-pressure air fan wheel blade are installed successively whitewashing rear side, rear side at negative-pressure air fan wheel blade is provided with motor, motor below is provided with charge power supply, electrostatic precipitator is installed below charge power supply, electrostatic precipitator below is provided with dust warehouse, whitewash, mesh plate is connected with the output shaft of motor by rotating shaft with negative-pressure air fan wheel blade, motor is all connected with charge power supply with electrostatic precipitator, also be provided with switch in hull outside, switch is connected with motor, on housing, also have gas outlet.The utility model is through the aspiration of negative pressure and electrostatic precipitation, and after repeatedly processing, chalk dust more than 95% is adsorbed in collecting bin, reduces and pollutes, and the chalk dust of collection can be processed into chalk again, and refuse is recycled, and turns waste into wealth, easy to use.
Description
Technical field
The utility model relates to realia technical field, relates in particular to a kind of environment-friendly dustless blackboard eraser.
Background technology
Teacher, in teaching process, inevitably will use chalk writing, and a large amount of chalk dust disperses, in air, are drawn onto lung by academics and students, grievous injury teachers and students healthy.Big in view of the harm of chalk dust, many people also once innovation and creation cross a variety of feature of environmental protection blackboard erasers, but effect is always undesirable, fails to be used more widely.
Utility model content
The utility model object is exactly the defect in order to make up prior art, and a kind of environment-friendly dustless blackboard eraser is provided.
The utility model is achieved through the following technical solutions:
A kind of environment-friendly dustless blackboard eraser, include 7 font handle type housings, be provided with and whitewash in the horizontal component left end of housing, outside whitewashing, be covered with telescopic cover, mesh plate and negative-pressure air fan wheel blade are installed successively whitewashing rear side, rear side at described negative-pressure air fan wheel blade is provided with motor, motor below is provided with charge power supply, electrostatic precipitator is installed below charge power supply, electrostatic precipitator below is provided with dust warehouse, described whitewashes, mesh plate is connected with the output shaft of motor by rotating shaft with negative-pressure air fan wheel blade, motor is all connected with charge power supply with electrostatic precipitator, also be provided with switch in hull outside, switch is connected with motor, on housing, also have gas outlet, air outlet place at electrostatic precipitator is provided with air filtering core, described air filtering core is aimed at the gas outlet on housing.
Front side in described motor and charge power supply is provided with baffle plate.
Driven by a motor, drive whitewash and negative pressure system in negative-pressure air fan wheel blade rotate.In the time that Dustless eraser contacts with plate face, starting switch.Whitewash under the driving of motor, blackboard eraser is parallel or move up and down, and whitewashes after the powder mark touching on plate face, and electronic rotation whitewashes automatic cleaning dust; The turbid air of a large amount of dust, in dust cover space, is sucked by negative pressure system; Enter electrostatic precipitation system, when dusty gas process high voltage electric field, separated by electricity, grit is combined and is brought after negative electricity with anion, and trend anode surface discharges and deposits, and reaches Purge gas and reclaim to be harmful to dust thing.Thereby utilizing electrostatic field to make gas ionization that dust particles is adsorbed onto on electrode gathers dust.In highfield, air molecule is ionized son and electronics, and electronics marches on towards in anodal process and runs into grit, and the electronegative positive pole that is adsorbed onto of grit is collected.The air of discharging in electrostatic precipitation system, enters in filtration system again by air filtering core, catches more tiny grit clean air is discharged; Remaining dust portion enters gathering system, is stored in temporarily collecting bin, and after collection is full, cleaning, in specified containers, to be again produced into chalk as raw material, reaches the effect of the cycling and reutilization of refuse.
The utility model has the advantages that: the utility model is through the aspiration of negative pressure and electrostatic precipitation, after repeatedly processing, chalk dust more than 95% is adsorbed in collecting bin, reduce and pollute, the chalk dust of collecting can be processed into chalk again, refuse is recycled, turns waste into wealth, easy to use, successful, is worthy to be popularized.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of environment-friendly dustless blackboard eraser, include 7 font handle type housings 1, be provided with and whitewash 2 in the horizontal component left end of housing 1, be covered with telescopic cover 3 whitewashing 2 outsides, mesh plate 11 and negative-pressure air fan wheel blade 4 are installed successively whitewashing 2 rear sides, rear side at described negative-pressure air fan wheel blade 4 is provided with motor 5, motor 5 belows are provided with charge power supply 6, electrostatic precipitator 7 is installed below charge power supply 6, electrostatic precipitator 7 belows are provided with dust warehouse 8, described whitewashes 2, mesh plate 11 is connected with the output shaft of motor 5 by rotating shaft with negative-pressure air fan wheel blade 4, motor 5 is all connected with charge power supply 6 with electrostatic precipitator 7, also be provided with switch 8 in housing 1 outside, switch 8 is connected with motor 5, on housing 1, also have gas outlet, air outlet place at electrostatic precipitator 7 is provided with air filtering core 9, described air filtering core 9 is aimed at the gas outlet on housing 1.
Front side in described motor 5 and charge power supply 6 is provided with baffle plate 10.
