Description
Technical field
The present invention relates to is used for erasing the board goes up the wiping board device of letter written with chalk, particularly relates to a kind of centrifugal chalk-collection double-bucket dust-catching blackboard eraser, belongs to educational aid.
Background technology
Teacher (teacher) writes on blackboard with chalk, and can cause dust from flying with Blackboard eraser wiping letter written with chalk, and the one, pollute indoor environment; The 2nd, be detrimental to health in the suction body.Therefore, people have developed dust suction wiping board device, the basic characteristics of dust suction wiping board device are that the induced-draught fan and the pipe of driven by motor leads to Blackboard eraser, after in the powder inhalation machine on the Blackboard eraser, filter, then discharge filter back air, the filter of existing wiping board device is a filter screen, and the shortcoming of its existence has: the one, and dust granules is little, filter screen can produce " leakage powder ", so still contain a powder in the air of discharging; The 2nd, because all powder all need pass through filter screen, filtration yield is big, and powder can be bonded on the filter screen, stops up opening of sieve, reduces filter capacity.
Summary of the invention
The objective of the invention is provides a kind of employing multistage filtering in order to overcome the shortcoming that prior art exists, and filter maintenance filter opening does not stop up good filtration effect, the clean centrifugal chalk-collection double-bucket dust-catching blackboard eraser of discharge air for a long time.
The technical scheme of centrifugal chalk-collection double-bucket dust-catching blackboard eraser of the present invention is: comprise the installation motor in the enclosure and the fan blade of driven by motor, motor housing is shaped on the inlet scoop, wind chamber and exhaust outlet, powder absorbing pipe is installed in the inlet scoop, powder absorbing pipe connects Blackboard eraser, the powder of suction hole is arranged in the Blackboard eraser, motor housing connects storage powder bucket down, filter powder device is arranged in the storage powder bucket, it is characterized in that described storage powder bucket comprises cylindrical shape powder bucket one Room and cylindrical shape powder bucket two Room, cylindrical shape powder bucket one Room and cylindrical shape powder bucket two Room are the disjunctor bucket, one-level filter powder jar is arranged in powder bucket one Room, be shaped on filter powder hole on the one-level filter powder tank skin, one-level filter powder jar links to each other with motor housing, the inlet scoop of shell is communicated with powder bucket one Room, the inlet scoop is facing to powder bucket one chamber interior walls, the end opening of one-level filter powder jar contacts with the boss of bottom, powder bucket one Room, suitable for reading the ganging up of one-level filter powder jar is opened on powder bucket two Room, secondary filter powder jar is arranged in powder bucket two Room, be shaped on the exhausting hole on the secondary filter powder tank skin, the connection exhaust outlet suitable for reading of secondary filter powder jar, one-level filter powder jar is shaped on eaves ring and following eaves ring, and filter powder hole is built in last, on the wall between the following eaves ring.
The present invention relates to a kind of multistage (two-stage) and filter dust suction wiping board device, double-filtration comprises two powder buckets and two filter powder jars, particularly inhale a next band powder air at first to the powder bucket from Blackboard eraser, a powder is deposited in the bucket, again the post-depositional air that contains a small amount of powder is sucked filter powder jar, the one, it is few to have contained a powder amount by the air of filtering powder jar filter powder hole, can avoid a powder too much to stop up filter powder hole; The 2nd, behind the employing double-filtration, essentially no dust in the air of Pai Chuing really reaches the dust suction purpose again.Whole flow direction about dust suction is such, the fan blade of driven by motor is installed in exhaust outlet, powder and air at first suck from Blackboard eraser, it is indoor to enter powder bucket one by powder absorbing pipe and inlet scoop, descend because the inlet scoop facing to powder bucket one chamber interior walls, makes a powder air-flow produce vortex and centrifugal, it is indoor that an overwhelming majority powder is deposited on powder bucket one, and cleaner air arrives in the jar by the filter powder hole of one-level filter powder jar, and enter powder bucket two Room, and siphoned away by the exhausting hole of secondary suction powder jar again, discharge cleaned air by exhaust outlet, dedusting is thorough, effective, and a powder do not have filter screen, avoids mesh to stop up, long service life, overcome cleaning filter screen trouble shortcoming simultaneously, its one-level filter powder jar is shaped on eaves ring and following eaves ring, and filter powder hole is built in last, on the wall between the following eaves ring, on having had, following eaves ring makes the major part of a powder directly not enter filter powder hole.
Centrifugal chalk-collection double-bucket dust-catching blackboard eraser of the present invention, the brush of its Blackboard eraser adopt the horsehair material made, and the not sticking powder of horsehair material separates easily, and is effective, long service life.The disjunctor bucket is made the transparent body for plastics, and disjunctor bucket intensity is good, the transparent barrel interior powdery condition of watching of staving.The upper diameter of its described one-level filter powder jar is greater than lower diameter, and the up big and down small air that helps up enters powder bucket two Room.
