Abstract
The invention discloses a cyclic utilization device for removing chalk dust by means of washing. The cyclic utilization device comprises a blackboard, pulleys, sliding rails, a tubular eraser and a water pump. The cyclic utilization device is characterized in that the sliding rails are arranged on the two sides of the blackboard; the pulleys matched with the sliding rails are arranged at the two ends of the tubular eraser; the tubular eraser can move vertically; a row of water spray holes are formed in the side, facing the blackboard, of the tubular eraser in the transverse direction; one end of the tubular eraser is connected with the water pump through a pipeline; a handheld housing is fixed to the outer side of the tubular eraser; a water collecting tank is arranged below the blackboard; the lower portion of one side of the water collecting tank is connected with one side of a filter device through a pipeline; and the other side of the filter device is connected with the water pump through a pipeline. The cyclic utilization device is simple in structure and convenient to use; and the chalk dust is adsorbed into water by means of washing, the phenomenon that the chalk dust flies is effectively avoided, and the health of teachers and students is protected.
Description
Technical field
The present invention relates to teaching aid, be specifically related to a kind of washing except chalk powder recycling device.
Background technology
In daily teaching, blackboard eraser is indispensable in teaching aid, the whole body ash that academics and students does when erasing the board also is wiped unclean, go down for a long time, the meeting healthy hidden danger of bringing to academics and students, and the source of the occupation disease chronic pharyngitis of teacher is chronically in the environment of chalk dust exactly, sucks what too many dust caused, and chalk powder fall into ground after not easily sweep, make troubles to student learning.
Summary of the invention
The purpose of the present invention is to provide one washing except chalk powder recycling device.
For achieving the above object, the present invention includes blackboard, pulley, slide rail, cast is wiped and water pump, it is characterized in that, it is provided with slide rail in blackboard both sides, described cast is wiped two ends and is provided with the pulley matched with slide rail, cast is wiped and can be moved up and down, wipe at cast and be provided with, towards blackboard side, the hole for water spraying that a row is transversely arranged, described cast is wiped one end and is connected by pipeline with water pump, wipe outside at cast and be fixed with hand rest case, described blackboard is transferred and is provided with water leg, it is connected by pipeline with defecator side at water leg one side-lower, described defecator opposite side is connected by pipeline with water pump.
By arrangement above, present configuration is simple, easy to use, by washing in chalk powder absorption and water, is effectively prevented powder and flies upward the generation of phenomenon, protect the health of academics and students.

Fig. 1 is present configuration schematic diagram.
Fig. 2 is the partial enlarged drawing in Figure 1A portion.
In figure: 1, blackboard, 2, cast wipe, 3, hand rest case, 4, pulley, 5, slide rail, 6, hole for water spraying, 7, water pump, 8, water leg, 9, defecator.
Detailed description of the invention
Such as Fig. 1, shown in 2, the present invention includes blackboard 1, pulley 4, slide rail 5, cast wipes 2 and water pump 7, it is characterized in that, it is provided with slide rail 5 in blackboard 1 both sides, described cast is wiped 2 two ends and is provided with the pulley 4 matched with slide rail 5, cast is wiped 2 and can be moved up and down, wipe 2 at cast and be provided with the transversely arranged hole for water spraying of a row 6 towards blackboard 1 side, described cast is wiped 2 one end and is connected by pipeline with water pump 7, wipe at cast and be fixed with hand rest case 3 outside 2, described blackboard 1 is transferred and is provided with water leg 8, it is connected by pipeline with defecator 9 side at water leg 8 one side-lower, described defecator 9 opposite side is connected by pipeline with water pump 7.
Pass through arrangement above, in use, water is delivered to cast and wipes 2 the present invention by water pump 7, and water is sprayed on blackboard by the hole for water spraying 6 wiped on 2 by cast, drag hand rest case 3 to move up and down simultaneously, hand rest case 3 drives cast to wipe 2 and moves up and down, and is cleaned by blackboard, and the mixture of water and chalk powder can fall in water leg 8 simultaneously, mixture flows in the defecator 9 below water leg 8, due to the effect of water pump 7, the water after filtering is arrived water pump 7 again, realizes recycling of water with this.
