Lay in reciprocating and turning-back in the plane of heating wire between heat transfer pad and heat insulating mattress.
The end of exhaust column is communicated with and stretches to dust removal and filtration tank.
Horizontal crossbearer is provided with handle.
The beneficial effect that the utility model is compared with prior art produced is:
This English teaching blackboard washing wiping drying device utilizes movement arm and horizontal crossbearer to coordinate sparge pipe to realize the object of blackboard for scrub water on the one hand, utilize on the other hand and set up heating wire at blackboard rear portion, the heating that heating wire can carry out to a certain degree to blackboard, improve the temperature of blackboard panel, contribute to the quick volatilization that blackboard panel is water stain; And utilize the design of dust hopper bottom blackboard, the propeller fan of additional negative-pressure ward, the dust air trapping that can well be produced by blackboard front face is in dust hopper, through axial fan, the air carrying dust secretly is passed in the tank of filter dirt pond, utilize water to be fallen by dust-filtering, form powder slurry.Suction effect like this also accelerates the speed air flow of blackboard panel, more contributes to the quick volatilization that blackboard panel is water stain.
This English teaching blackboard washing wiping drying device makes blackboard adopt the wiping of rinsing type, and it is efficient and convenient, improves the quality of teaching.
The dry apparatus design of this English teaching blackboard washing wiping is reasonable, structure is simple, safe and reliable, easy to use, be easy to safeguard, have good value for applications.
