Description
Technical field
The utility model relates to technical field of dust absorption, refers to a kind of dust absorbing device especially.
Background technology
Existing dust exhaust apparatus provides negative pressure by negative pressure device mostly, is then absorbed in retracting device via pipeline by dust under the effect of negative pressure.In concrete use, negative pressure device mostly is motor, and because a large amount of dust is invaded during motor operation, electrical fault takes place frequently, and has had a strong impact on the service life of motor, has increased the running cost of dust suction effect.
Utility model content
For solving above the deficiencies in the prior art, the utility model proposes one can effectively reduce negative pressure device fault rate, extends the dust absorbing device in negative pressure device service life.
The technical solution of the utility model is achieved in that
A kind of dust absorbing device, comprising: dust shield, elbow couplings, collection bag and negative pressure device, the bend pipe that elbow couplings comprises first mouth of pipe, second mouth of pipe and is located between first mouth of pipe and second mouth of pipe;
Bend pipe is circumscribed with arc siphunculus, and the radian of arc siphunculus is greater than the radian of bend pipe, and dust shield is connected with second mouth of pipe, and collection bag is connected with arc siphunculus by connector, and negative pressure device is connected with first mouth of pipe, is provided with filtration members in first mouth of pipe.
Preferably, the inwall of dust shield is provided with shaggy dust suction layer.
Preferred further, connector is flange.
More preferred, filtration members is porous ceramic filter element.
The dust absorbing device scientific structure that the utility model proposes, arrange rationally, solve dust in cleaning operation easily to enter negative pressure device, affect the problem in negative pressure device service life, effectively can reduce the fault rate of negative pressure device, extend the service life of negative pressure device, decrease the running cost of dust absorbing.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure: 1, elbow couplings; 11, first mouth of pipe; 12, second mouth of pipe; 13, filtration members; 2, arc siphunculus; 3, connector; 4, collection bag; 5, dust shield; 6, negative pressure device.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1: a kind of dust absorbing device, comprising: dust shield 5, elbow couplings 1, collection bag 4 and negative pressure device 6, elbow couplings 1 comprises first mouth of pipe 11, second mouth of pipe 12 and is located at the bend pipe between first mouth of pipe 11 and second mouth of pipe 12;
Bend pipe is circumscribed with arc siphunculus 2, the radian of arc siphunculus 2 is greater than the radian of bend pipe, and dust shield 5 is connected with second mouth of pipe 12, and collection bag 4 is connected with arc siphunculus 2 by connector 3, negative pressure device 6 is connected with first mouth of pipe 11, is provided with filtration members 13 in first mouth of pipe 11.
Operation principle: under the effect of negative pressure device 6, dust shield 5 absorbs the dust in working environment, dust enters through second mouth of pipe 12 of elbow couplings 1, under centrifugal action, dust can enter the arc siphunculus 2 communicated with elbow couplings 1, then enters in the collection bag 4 be connected with arc siphunculus 2.Enter negative pressure device 6, first mouth of pipe 11 place be connected with first mouth of pipe 11 be provided with filtration members 13 in order to avoid remaining a small amount of dust, hinder dust to enter negative pressure device 6 further, extend the service life of negative pressure device 6.
The dust absorbing device scientific structure that the utility model proposes, arrange rationally, solve dust in cleaning operation and easily enter the problem of negative pressure device, effectively can reduce the fault rate of negative pressure device, extend the service life of negative pressure device, decrease the running cost of dust absorbing.The utility model is not only applicable to building field, also may be used for the place that other need dust suction.
As the preferred technical scheme of one, an embodiment more of the present utility model, the inwall of dust shield 5 is provided with shaggy dust suction layer.
Existing dust shield is mostly the dust shield of inner wall smooth, and when dust can not be siphoned away in time, the dust being attached to dust shield inwall just can drop, and is degrading operating environment further.Therefore, by being provided with shaggy dust suction layer on the inwall of dust shield 5, the dust be not sucked away in time temporarily can being adsorbed on dust suction layer, avoiding the generation airborne dust that drops.
As the preferred technical scheme of one, another embodiment of the present utility model, connector 3 is flange.
As the preferred technical scheme of one, another embodiment of the present utility model, filtration members 13 is porous ceramic filter element.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
