Environment.
Utility model content
The technical problems to be solved in the utility model is in view of the foregoing drawbacks, to provide a kind of chalk dust retracting device, the powder
Dirt retracting device is convenient for the recycling of chalk dust.
In order to solve the above technical problems, the utility model includes blackboard body, it is characterized in that：The blackboard body length side
To both ends be equipped with recycling bins, the relative inner portion opening of two recycling bins is equipped with separation filter plate in two recycling bins, separates
The inner cavity of recycling bins is divided into the reclaiming chamber of the placed cavity and front at rear portion by filter plate, and exhaust fan, exhaust fan are equipped in placed cavity
Air inlet and separate filter plate it is affixed, recycling bins be equipped with outlet corresponding with exhaust fan air outlet；The bottom wall of the reclaiming chamber
It is equipped with outlet from recycling bins opening portion to setting, the lowest point of reclaiming chamber bottom wall is tilted down inside it, the exit passes through
Connecting tube is connected with accommodating case.
The opening portion of two recycling bins is equipped with kuppe.
The kuppe is in horn-like setting.
Be arranged with the reinforcing plate of opposed, inwardly directed extension on the inner wall of the recycling bins, the separation filter plate trailing flank with plus
The leading flank of strong plate is affixed.
The top of the blackboard body is equipped with the shutter for tilting down setting.
The bottom of the accommodating case is equipped with discharge port, and discharge outlet is bolted with sealing cover.
Exhaust fan there are two being symmetrical arranged in each placed cavity.
The utility model has the following advantages compared with prior art：Writing on the blackboard or when wiping blackboard, starts exhaust fan, chalk
Dirt is inhaled under the action of kuppe in reclaiming chamber, and kuppe can increase the sucking range of chalk dust, is separating filter plate
Under effect, chalk dust, which is filtered, to be stayed in reclaiming chamber, and the wind of sucking is discharged by exporting.The bottom wall of reclaiming chamber recycles box opening certainly
Portion is equipped with outlet to setting, the lowest point of reclaiming chamber bottom wall is tilted down inside it, and chalk dust is slipped to out after entering reclaiming chamber
At mouthful, exit is connected with accommodating case by connecting tube, and chalk dust is entered by outlet in accommodating case, and long-term accumulation chalk dust can
To be discharged from the discharge port of accommodating case.
In conclusion the utility model is convenient for the recycling of chalk dust, and it is simple in structure, it is easy to use.
Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is sectional view along A-A in Fig. 1.
Specific implementation mode
Chalk dust retracting device as Figure 1-Figure 2, including blackboard body 1, the both ends of 1 length direction of blackboard body
Recycling bins 2 are equipped with, recycling bins 2 are fixed on the wall in the present embodiment, the relative inner portion opening of two recycling bins 2 recycles
Case 2 is equipped in two recycling bins 2 towards a side mouth of blackboard body 1 and separates filter plate 3, and the both ends for separating filter plate 3 are solid
It is connected on the inner wall of recycling bins 2, the reinforcing plate 8 of opposed, inwardly directed extension is arranged on the inner wall of recycling bins 2, after separating filter plate 3
Side and the leading flank of reinforcing plate 8 are affixed, and reinforcing plate 8 can improve the installation strength for separating filter plate 3.Separate filter in the present embodiment
The inner cavity of recycling bins 2 is divided into the reclaiming chamber 22 of the placed cavity 21 and front at rear portion by plate 3, and exhaust fan 4 is equipped in placed cavity 21,
There are two exhaust fan 4 is symmetrical arranged, the uniformity of sucking is improved, the air inlet and separation filter plate 3 of exhaust fan 4 are affixed, recycling bins 2
It is equipped with outlet corresponding with 4 air outlet of exhaust fan.The opening portion of two recycling bins 2 is equipped with kuppe 7, and kuppe 7 is in loudspeaker
Shape is arranged, and increases the absorption region of chalk dust.
As shown in Figure 1, the bottom wall of reclaiming chamber 22 is from 2 opening portion of recycling bins to tilting down setting, reclaiming chamber 22 inside it
The lowest point of bottom wall is equipped with outlet 23, and chalk dust is slipped to after entering reclaiming chamber 22 at outlet 23, passes through connecting tube 5 at outlet 23
