Description

Chalk end reclaims and resets chalk device
Technical field
The invention belongs to teaching aid, be specifically related to a kind of recovery reset apparatus being used for reclaiming chalk dust and chalk end.
Background technology
In the education activities of school, still use chalk in a large number at present.When using chalkboard eraser erasing, chalk dust can enter air, harm surrounding environment.It is healthy that Faculty and Students suck chalk dust meeting serious threat, and therefore many teachers suffer from PUD D.Teacher always leaves a little section header after chalk writes, because hand has been difficult to hold its recycling, it has write, and common way has been thrown away chalk end exactly, waste resource, contaminated environment.
Present urgent need wants a kind of technology, chalk end and chalk dust all effectively can be recycled and reused.
Summary of the invention
For deficiency of the prior art, the invention provides a kind of recovery reset apparatus being used for reclaiming chalk dust and chalk end, solve chalk, grey chalk end, the problem of contaminated environment waste resource.
The present invention is achieved through the following technical solutions.
Chalk end reclaims and resets chalk device, it is characterized in that, comprises and inhales component powder, adhesive assembly and pressure assembly, and described suction component powder comprises the blackboard eraser that powder mouth inhaled by band, and described blackboard eraser is connected with pressure assembly by flexible duct; Described adhesive assembly comprises the fixed-piping be connected with pressure assembly, described fixed-piping is also provided with air pump with for adding the window of adhesive; Described pressure assembly comprises mixing drum and can be pressed into the piece under pressure in described mixing drum, and described mixing drum bottom is provided with heater block.
In use, chalk end is put into described chalk end entrance, after chalk end arrives bottom valve, 2 time switch outlets are opened respectively, air pump above fixed-piping makes there has been hyperbar in pipe, the time switch outlet on the right is ejected adhesive carboxymethyl cellulose and is added aqueous mixtures, the time switch outlet evenly unrestrained chalk dust on the left side, after second piece of chalk end is lost, mixing drum sidewall is provided with heater block and starts opening timing heating, open telescope motor, the expansion link being wrapped in rubber layer slowly declines, in mixing drum, drop to the upper end of second piece of chalk end and give certain pressure, slowly original position is risen to after a period of time, repeat above-mentioned step to play, wait that spliced chalk length arrives inductor place, the valve open chalk of bottom is sent.
As preferably, described piece under pressure comprises telescope motor, is provided with fixed bar below described telescope motor, is provided with expansion link below described fixed bar, the outer wrap of described expansion link rubber layer.Ensure that chalk is not crushed in the middle of adhesion process of exerting pressure.
As preferably, the internal diameter size of described mixing drum and chalk are matched in clearance.When this ensure that chalk end puts in certainly be vertically towards, convenient bonding.
As preferably, 2 described time switches outlets are Turbogrid plates outlet and the timing arranged is different.The outlet of 2 time switches is made Turbogrid plates and is conducive at uniform discharge, arranges the different time can ensure that chalk dust adds aqueous mixtures with adhesive carboxymethyl cellulose and mixes.
As preferably, described flexible duct is a kind of flexible duct of folding plastic.Folding plastic can stretch, and the flexible duct of stretching both can give the wire that one, the dust of suction is suitable, also facilitated chalkboard eraser to wipe each corner of blackboard.
As preferably, above described mixing drum, there is an inductor.Compacting chalk unified specification out can be made, not too high short only.
As preferably, described heater block is timing electromagnetic induction heater.Hot mode of heating in energy-efficient, Fast Heating adopts, reduces production cost, improves the quality of products.
Compared with prior art, the present invention has following beneficial effect: chalk dust and chalk end are all recycled, energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described further.
See Fig. 1, chalk end reclaims and resets chalk device, comprise and inhale component powder, adhesive assembly and pressure assembly, described suction component powder, adhesive assembly and pressure assembly are all installed within the case 1, described housing 1 is arranged on below blackboard slot 17, described housing 1 is provided with the connector 2 in the hole containing installing hole, described suction component powder comprises the blackboard eraser 12 that powder mouth inhaled by band, and described blackboard eraser 12 is connected with pressure assembly by flexible duct 13; Described adhesive assembly comprises the fixed-piping 16 be connected with pressure assembly, described fixed-piping 16 is also provided with air pump 14 with for adding the window 15 of adhesive; Described flexible duct 13 is provided with time switch with fixed-piping 16 and exports 7, the piece under pressure that described pressure assembly comprises mixing drum 4 and can be pressed in described mixing drum 4, and described mixing drum 4 bottom is provided with heater block 3.Described mixing drum is also provided with inductor 6, with the valve 5 being arranged on bottom, described piece under pressure comprises telescope motor 8, is provided with fixed bar 9 below described telescope motor, below described fixed bar 9, expansion link 10 is installed, the outer wrap of described expansion link 10 rubber layer 11.
In use, chalk end is put in described chalk end entrance 18, after chalk end arrives bottom valve 5, 2 time switch outlets are opened respectively, air pump 14 above fixed-piping makes there has been hyperbar in pipeline, the time switch outlet 7 on the right is ejected adhesive carboxymethyl cellulose and is added aqueous mixtures, the time switch outlet 7 evenly unrestrained chalk dust on the left side, after second piece of chalk end is lost, mixing drum 4 sidewall is provided with heater block 3 and starts opening timing heating, open telescope motor 8, the expansion link 10 being wrapped in rubber layer 11 slowly declines, in mixing drum 4, drop to the upper end of second piece of chalk end and give certain pressure, slowly original position is risen to after a period of time, repeat above-mentioned step to play, wait that spliced chalk length arrives inductor 6 place, the valve 5 of bottom is opened chalk and is sent.
Protection scope of the present invention includes but not limited to above embodiment, and protection scope of the present invention is as the criterion with claims, and any replacement that those skilled in the art will find apparent that, distortion, improvement made this technology all falls into protection scope of the present invention.
