Be used for the dustproof control cubicle under the bad working environments
Technical field
The utility model belongs to machine tool, is specifically related to a kind of control cubicle.
Background technology
Control cubicle is the indispensable parts of machine tool, and it is inner general to be equipped with comparatively crucial control, equipment such as electric.For guaranteeing device security; Generally require the inner maintenance of control cubicle clean, dry, for reaching time purpose, general way is at the sidewall of control cubicle or rear wall one or more fans to be installed; By the air convection current inside and outside control cubicle between the fan belt motor-car, thereby play the effect of cooling, dedusting.Yet in the actual job, the operating mode of control cubicle is generally comparatively abominable, and for example dust is many in the operational environment, and cooling water can produce a large amount of water smokes or the like.During the fan work of control cubicle, drive the cross-ventilation in the operational environment, thereby can bring a large amount of dusts into control cubicle, dust be attached on the control cubicle internal unit after the water in air mist combines, reduce equipment life, cause short circuit in the time of seriously, cause equipment to damage.
With the wood carving machine is example; Its production scene exists a large amount of wood chips, water smoke, brought into control cubicle by fan after, wood chip and water smoke are deposited on the equipment; Can cause short circuit when moist; Heating after control cubicle works long hours, the moistening wood chip of its inside deposition are dry gradually, and working long hours is prone to cause control cubicle accident on fire.
Summary of the invention
The utility model technical problem to be solved is under bad working environments, guarantees that control cubicle is inner clean, prevents dust deposit, stops potential safety hazard.
For achieving the above object, the technical scheme of the utility model comprises cabinet, is connected with blower fan on the cabinet, and the air inlet of blower fan is sealedly connected with air inlet pipe.
After having adopted technique scheme, the inlet of air inlet pipe is arranged at the outdoor pure air environment that waits, during control cubicle work; Blower fan sucks pure air through air inlet pipe, and is blown into control cubicle inside, to control cubicle inside lower the temperature, dedusting; Because what blower fan sucked is outside pure air, thereby not influenced by on-the-spot abominable air ambient, can guarantee that control cubicle is inner clean; Prevent dust deposit, stop potential safety hazard.
Further, the utility model be used for the dustproof control cubicle under the bad working environments, be sealedly connected with air filter on its air inlet pipe.After adopting this technical scheme; Air inlet pipe and air filter can directly be positioned over the working site; After by air filter the contaminated air of bad working environments environment being carried out filtering, be delivered to control cubicle inside, appoint to guarantee that so control cubicle is inner clean dustless through blower fan.
Description of drawings
Fig. 1 is the sketch map that is used for the dustproof control cubicle embodiment one under the bad working environments of the utility model;
Fig. 2 is the sketch map that is used for the dustproof control cubicle embodiment two under the bad working environments of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Embodiment one
Visible by Fig. 1, present embodiment comprises cabinet 1, perforate and be sealedly connected with blower fan 2 on the cabinet 1, and the air inlet of blower fan 2 is sealedly connected with air inlet pipe 3.Air inlet pipe 3 has enough length, and cabinet 1 is deployed in the scene, workshop, and air inlet pipe 3 places outdoor or other pure air positions, thereby 3 suctions of assurance air inlet pipe is pure air.During control cubicle work, under blower fan 2 drives, gather pure air from the external world by air inlet pipe 3; And be delivered to cabinet 1 inside; The air driven cabinet 1 inner louvre 5 of small amount of dust impurity on cabinet 1 discharged with all the other slits, guarantees the cleaning of cabinet 1 inside, possesses the cooling function simultaneously.
Embodiment two
Visible by Fig. 2, present embodiment comprises cabinet 1, perforate and be sealedly connected with blower fan 2 on the cabinet 1, and the air inlet of blower fan 2 is sealedly connected with air inlet pipe 3, is sealedly connected with air filter 4 on the air inlet pipe 3.Present embodiment is applicable to and limited by site environment that air inlet pipe 3 is difficult to dispose, the situation of pure air collection inconvenience.In the present embodiment, air inlet pipe 3, air filter 4 can directly be arranged under the bad working environments of working site, and non-clean gas is gone into blower fan 2 through air filter 4 filterings are laggard, again cabinet 1 is carried out dedusting cooling operation.Because on-the-spot air has been carried out filtering, can guarantee still that therefore control cubicle is inner clean, prevent dust deposit, stop potential safety hazard.
