Description
Technical field
The utility model relates to the technical field of electrical control cabinet, the external air circulation device of especially a kind of electrical control cabinet.
Background technology
Electrical control cabinet inside is provided with instrument and the equipment of a lot of precisions, needs to ensure the inner good operational environment that has, could normal stable running.Existing electrical control cabinet in use, can not meet these requirements.The heat that some airtight cabinets produce in the time of work is difficult to be lost to outside cabinet, affects equipment operation; And the control cubicle with ventilation easily has the granule foreigns such as dust to enter in cabinet, and under moist weather, cabinet inside also easily produces to drip reveals, and brings larger harm, so a control cubicle that meets above function is very important to equipment.
Utility model content
The technical problems to be solved in the utility model is: for solving the problem of above-mentioned existence, provide a kind of electrical control cabinet external air circulation device.
The utility model solves the technical scheme that its technical problem adopts: the external air circulation device of a kind of electrical control cabinet, comprise cabinet, the sidewall upper of cabinet is provided with exhaust apparatus, the side wall lower ends of cabinet is provided with inlet duct, between exhaust apparatus and inlet duct, be connected with dust filter, control valve and air dewetting tank in turn by connecting line, the top of dust filter is provided with humidity sensor, and humidity sensor connects control device with control valve by being connected wire.
Further, dust filter bottom is also provided with unidirectional relief valve, and unidirectional relief valve is connected with inlet duct by connecting line.
Further, dust filter comprises housing and is arranged on the air filtering core in housing.
Further, exhaust apparatus and inlet duct are turbine fan.
The beneficial effects of the utility model are, the external air circulation device of electrical control cabinet of the present utility model is simple in structure, the scope of application is extensive, meet the instructions for use of different operating environment, by air circulation device being set at cabinet outward, overcome the deficiency of existing control cubicle, the air in can circular treatment cabinet, reduce airborne impurity and moisture, provide good condition of work for the electric equipment in cabinet runs well.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. cabinets in figure, 2. exhaust apparatus, 3. inlet duct, 4. connecting line, 5. dust filter, 6. control valve, 7. air dewetting tank, 8. humidity sensor, 9. control device, 10. unidirectional relief valve.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The external air circulation device of electrical control cabinet as shown in Figure 1, comprise cabinet 1, the sidewall upper of cabinet 1 is provided with exhaust apparatus 2, the side wall lower ends of cabinet 1 is provided with inlet duct 3, between exhaust apparatus 2 and inlet duct 3, be connected with dust filter 5 in turn by connecting line 4, control valve 6 and air dewetting tank 7, the top of dust filter 5 is provided with humidity sensor 8, humidity sensor 8 connects control device 9 with control valve 6 by being connected wire, dust filter 5 bottoms are also provided with unidirectional relief valve 10, unidirectional relief valve 10 is connected with inlet duct 3 by connecting line 4, dust filter 5 comprises housing and is arranged on the air filtering core in housing, exhaust apparatus 2 and inlet duct 3 are turbine fan.
In the course of work, exhaust apparatus 2 and inlet duct 3 energising runnings, air in cabinet 1 passes through exhaust apparatus 2, dust filter 5, control valve 6, air dewetting tank 7 and inlet duct 3 circulation successively, in the time that the humidity sensor 8 at dust filter 5 tops detects that air humidity is very low, control device 9 closed control valves 6, air is assembled in dust filter 5, while reaching certain pressure, unidirectional relief valve 10 is opened, air flows to inlet duct 3 through connecting line 4, completes a new duty cycle.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.
