Abstract
The invention discloses a chalk dust removing system. The chalk dust removing system comprises a blackboard, a dust-absorbing device is installed above the blackboard, a controller is connected with a dust-absorbing device control relay through a wire, and the dust-absorbing device control relay is connected with the dust-absorbing device through a wire. According to the invention, problems that when a teacher gives lessons in a classroom, the teacher writes on the blackboard with a chalk, when the blackboard is cleaned, dust flies and can be absorbed by the lung easily, and physical health of the teacher is severely influenced, and dust is not benefit for environmental sanitation are solved.
Description
Technical field
The invention belongs to chalk dust dedusting technology, particularly relate to a kind of chalk dust scavenge system.
Background technology
When the place teachers such as school give lessons mainly or adopt and on blackboard, write letter written with chalk carry out, although a lot of colleges and universities have adopted lantern slide etc. to carry out, but still write mainly through chalk in vast rural area and carry out, after chalk-writing when erasing the board, chalk dust can fly around, dust is easily drawn onto in lung and has had a strong impact on the healthy of teacher, nor is beneficial to environmental sanitation.
Summary of the invention
The technical problem to be solved in the present invention: a kind of chalk dust scavenge system is provided, adopt during to solve that in classroom, teacher gives lessons and write letter written with chalk on blackboard, the dust that dust disorderly flies to cause when erasing the board easily is drawn onto in lung and has had a strong impact on the healthy of teacher, nor is beneficial to the problems such as environmental sanitation.
Technical solution of the present invention:
A kind of chalk dust scavenge system, it comprises blackboard, above blackboard, be provided with dust exhaust apparatus, and controller is connected with dust exhaust apparatus control relay wire, and dust exhaust apparatus controller relay is connected with dust exhaust apparatus wire.
Described dust exhaust apparatus is dust absorption fan.
On blackboard, below blackboard and above all dust detection sensors is installed.
Beneficial effect of the present invention:
The present invention adopts and install induced-draught fan above blackboard, when needs open induced-draught fan except during chalk dust, by induced-draught fan, chalk dust is drawn onto the special dust depository of induced-draught fan, in order to save electric energy and strengthen automation, dust detection sensors installed by blackboard, chalk dust is detected by dust detection sensors, and detection signal is delivered to controller, when dust exceeds standard, controller automatic decision, output signal to dust exhaust apparatus controller relay, connect dust exhaust apparatus power supply, dust exhaust apparatus is started working, adopt when the invention solves that in classroom, teacher gives lessons and write letter written with chalk on blackboard, the dust that dust disorderly flies to cause when erasing the board easily is drawn onto in lung and has had a strong impact on the healthy of teacher, nor be beneficial to the problems such as environmental sanitation.
accompanying drawing illustrates:
Fig. 1 is present system composition schematic diagram.
detailed description of the invention:
A kind of chalk dust scavenge system, it comprises blackboard, above blackboard, be provided with dust exhaust apparatus, and controller is connected with dust exhaust apparatus control relay wire, and dust exhaust apparatus controller relay is connected with dust exhaust apparatus wire.
Described dust exhaust apparatus is dust absorption fan.
Blackboard is provided with dust detection sensors, in order to chalk dust be detected reliably, below blackboard and above all dust detection sensors is installed.
