Abstract
The utility model relates to a dust removing system, and in particular relates to a blackboard dust removing system which is applied to a teaching blackboard in a school. The blackboard dust removing system comprises an air inlet, an air duct, a humidifier, a sedimentation tank, an exhaust fan and an air outlet. The blackboard dust removing system is powered by the exhaust fan. Dusty gas is drawn by the air inlet. Humidifying and sedimentation are carried out, and the gas after dust removing is discharged from the air outlet. The problem of chalk dust pollution in a classroom is solved, and the environment in the classroom is improved.
Description
Technical field
The utility model belongs to realia technical field, is specifically related to a kind of blackboard chalk dust removing system.
Background technology
Widely used blackboard is installed ash-pit and is collected chalk dust below blackboard in the market, but when writing, erasing the board and when the situations such as wind met by ash-pit, can produce airborne dust, pollutes classroom environment, affects the healthy of Faculty and Students.
Utility model content
The above-mentioned defect existing in order to overcome prior art field, the purpose of this utility model is, a kind of blackboard chalk dust removing system is provided, and solves the problem that the reasons such as chalk-writing in classroom cause dust pollution.
The blackboard chalk dust removing system that the utility model provides, is applied to, on blackboard, comprise air inlet, air channel, air exhauster, humidifier, sedimentation basin and air outlet, and air inlet is arranged on around blackboard, and air exhauster, humidifier and sedimentation basin are arranged on air channel successively.
The blackboard chalk dust removing system that the utility model provides, it is preferably designed for: described air inlet is four, is arranged on respectively blackboard surrounding.
Meanwhile, also comprise filter screen, be arranged on air outlet place.
The blackboard chalk dust removing system that the utility model provides, its beneficial effect is, removes dust, reduces and pollutes, and improves teaching environment quality.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, mark:
1. air inlet; 2. air channel; 3. humidifier; 4. sedimentation basin; 5. air exhauster; 6. filter screen; 7. air outlet; 8. blackboard.
The specific embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, a kind of blackboard chalk dust removing system that the utility model is provided is described in detail.
With reference to Fig. 1, a kind of blackboard chalk dust removing system of the present embodiment, be applied on blackboard 8, comprise air inlet 1, air channel 2, humidifier 3, sedimentation basin 4, air exhauster 5 and air outlet 7, air inlet 1 is arranged on around blackboard 8, and air exhauster 5, humidifier 3, sedimentation basin 4 and air outlet 7 are arranged on air channel 2 successively.
During work, air exhauster 5 and humidifier 3 work, enter in air channel 2 from air inlet 1 containing dusty gas, through air exhauster 5, arrive humidifier 3 places, containing dusty gas, be combined with the gas of humidifier 3, because gravity reason precipitates gradually at sedimentation basin 4 places, the gas after chalk dust removing is discharged from air outlet 7.Complete chalk dust removing process, improve the environment in classroom, protect the healthy of Faculty and Students.
A kind of blackboard chalk dust removing system of the present embodiment, described air inlet 1 is four, is arranged on respectively blackboard 8 surroundings, can carry out chalk dust removing, better effects if from four direction.
In addition, also comprise filter screen 6, be arranged on air outlet 7 places, the gas after chalk dust removing is further filtered, guarantee that the gas of discharging is dustless.
