Abstract
The utility model relates to a dust and water filter device for blackboard, which comprises a removable dust and water collecting tank is arranged at the lower of the blackboard, a baffle is arranged in the slot of the dust and water collecting tank, and the dust and water collecting tank is divided into two parts, namely the upper part for placing eraser and the lower part for collecting dust and water, a plurality of holes are positioned on the baffle to let the water and dust go through. Based on the technical proposal, the writing mark and duct can be flush away from the blackboard by water one-time, then dirty water flows into dust and water collecting tank through the baffle. When the collecting tank is full of dust and water, the collecting tank can be removed from the blackboard, and the dust can be removed to other container for regeneration and utilization. Thus the dust pollution issue can be solved completely. The utility model has the advantages of simple structure, low cost and other advantages.
Description
Technical field
The utility model relates to a kind of blackboard filter dirt water treatment plant, belong to the instruments used for education field.
Background technology
Generally after writing, blackboard wipes examination with blackboard eraser, because having many dust in the wiping examination process wafts in air, can cause the serious pollution of air like this, directly influence the healthy of teacher and student, solved dust problem, a kind of method is treated to clean after the dust landing for to use the blackboard eraser wiping in the past, with the removing dust, but this still can be polluted in cleaning dust process; Also useful wet blackboard eraser wiping because water can't stockpile, therefore can not be removed writing effectively.
In order to solve the problem of dust pollution, China patent application patent CN1050002 discloses a kind of electrical dust-removing blackboard eraser, one ac micro motor is installed in the motor casing that has handle, stretch on the motor shaft in the spiral case impeller, hairbrush are installed, have a dividing plate to be connected by a ventilation duct and tip fastening box above it in the spiral case.Wall be provided with air vent in have the tip fastening box of sponge filter screen to be located in the capsul, on the spiral case below dividing plate once the air port communicate with capsul.Utilize hairbrush to wipe air-flow that powder down and dust produce with the impeller rotation and be controlled at by spiral case and capsul that circulate repeatedly in its inside and the purpose of the method realization dedusting of filtering.
Utility model patent CN2347785 discloses a kind of blackboard eraser dust arrester, it is by air outlet, housing, shock absorber, motor, middle cover, loam cake, blade, rubber ring, magnet, the cloth filter bag, the sponge filter bag, the chalk chamber, power interface, carry hand, power switch, electric machine support, motor coil, supporting station, boss, air inlet, the powder air inlet, air outlet, rubber mount constitutes, it is characterized in that: the sponge filter bag is less than the cloth filter bag and in the cloth filter bag, the cloth filter bag is in the powder air inlet, at the last air inlet that covered, boss, motor is below the powder air inlet.Be characterized in: the sponge filter bag is less than the cloth filter bag and in the cloth filter bag, and the cloth filter bag is in the powder air inlet, and at last air inlet, the boss of having covered, motor is below the powder air inlet.On the cloth filter bag, rubber mount is arranged.
Utility model patent CN2501698 discloses the electronic wiping of dustproof dedusting that a kind of hairbrush can any direction moves on blackboard, and it is made of left and right on blackboard, the upper and lower mobile transmission mechanism of control hairbrush, the mechanism and the dust remover of control blackboard brush contact blackboard degree.Left and right mobile transmission mechanism is made of chain motor, sprocket wheel, chain, pitching pile, cross slide way, slip rail etc.Exposure level is made of advance and retreat disk, screw mandrel, split pin, guide post, motor etc.This device adopts control, the transmission mechanism of three directions, and it is moving to make hairbrush can do the displacement of up, down, left, right, before and after each side on blackboard.
Though above-mentioned dust arrester can solve dust problem effectively because its complex structure, cost are higher, to such an extent as to can't popularize use, therefore, a kind of simple in structure, cost is low and the blackboard of effective dedusting filter dirt water treatment plant becomes required.
Summary of the invention
The purpose of this utility model is to provide a kind of blackboard filter dirt water treatment plant, and this apparatus structure is simple, and cost is low, and dedusting is thorough, and is easy to use.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of blackboard filter dirt water treatment plant, it comprises: one is installed in dismountable water storage dust collecting trough of blackboard bottom, in the groove of water storage dust collecting trough, be provided with a dividing plate, described dividing plate is divided into the blackboard eraser seating part of top and following dust, water storage compartment with the water storage dust collecting trough, has the hole that several water supply and dust pass through on described dividing plate.
Described dividing plate is positioned at the water storage dust collecting trough.
Described dividing plate is preferably reticular lamina.
Owing to adopt technique scheme, adopt the wet rubbing water-washing method that writing and the dust of writing on all kinds of blackboards once washed away, make it flow into drainage filter dirt trench bottom through dividing plate, dust collects full dust in water storage filter dirt groove after, can take off drainage filter dirt groove, dust collection is prepared against regeneration in other container.Thereby thoroughly solve dust and pollution problem, its have simple in structure, cost is low, advantage such as easy to use and reusable.
Description of drawings
Fig. 1 is the schematic diagram that blackboard filter dirt water treatment plant of the present utility model is installed in the blackboard front;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Among the figure: 1 is blackboard; 2 are drainage filter dirt groove; 3 is dividing plate.
The specific embodiment
Referring to Fig. 1-3, showed a kind of blackboard filter dirt water treatment plant among the figure, this device is removably mounted on the below of blackboard 1, it comprises: a water storage dust collecting trough 2, and it is installed in blackboard 1 bottom, and can dismantle easily, in the groove of water storage dust collecting trough 2, be provided with a dividing plate 3, described dividing plate 3 is divided into upper and lower two parts with water storage dust collecting trough 2: top is blackboard eraser seating part 5, is dust, water storage compartment 6 below, has the hole 4 that several water supply and dust pass through on described dividing plate 3.Adopt the wet rubbing water-washing method that writing and the dust of writing on all kinds of blackboards once washed away, make it flow into the bottom of drainage filter dirt groove 2 through the hole on the dividing plate 34: dust, water storage compartment 6, after dust collects completely in dust, water storage compartment 6, can take off drainage filter dirt groove 2, dust collection is prepared against regeneration in other container.Thereby thoroughly solve dust and pollution problem.Described dividing plate 3 is positioned at water storage dust collecting trough 2 1/2 and highly locates, so that following dust, water storage compartment 6 have bigger space, and make blackboard eraser can be placed in dividing plate 3 above, described dividing plate 3 is preferably reticular lamina, so that dust and water more easily flow into the bottom of water storage dust collecting trough 2.
