Abstract
The utility model provides a back blowing dust removal device for a fan of an air-cooled water chiller, which comprises a heat radiating fan. A corotating control circuit and a contrarotating control circuit are connected on the heat radiating fan; a corotating control switch is arranged on the corotating control circuit; a contrarotating control switch is arranged on the corotating control circuit; the corotating control switch and the contrarotating control switch are respectively connected with a switch controller through a lead wire; and the switch controller is connected with a master control circuit through a lead wire. The utility model has the advantages that the structure is reasonable, so that the heat radiating fan of the air-cooled water chiller can operate timely and reversely to generate certain wind pressure; dust deposited on heat radiating fins and other places can be blown down by means of the wind pressure and then carried away via airflow formed by the fan, so as to greatly reduce the shunting and cleaning times of the water chilling unit, ensure the refrigerating efficiency, and save labors and materials.
Description
Technical field
The utility model relates to a kind of radiation fan of wind-cooled cold-water unit, specifically a kind of wind-cooled cold-water unit fan blowback dust removal apparatus.
Background technique
The wind-cooled cold-water unit needs to use fan to dispel the heat in use; radiation fan can also be taken the dust of handpiece Water Chilling Units inside deposition out of in heat radiation; but dust deposit is located at radiating fin etc. sometimes; be difficult for being taken out of by the air-flow that fan forms; dust deposit too much can influence the refrigerating efficiency of handpiece Water Chilling Units; therefore people need regularly water chiller to be shut down cleaning, need expend a large amount of time and human and material resources.
Summary of the invention
The purpose of this utility model provides a kind of wind-cooled cold-water unit fan blowback dust removal apparatus, it can make the radiation fan timing inverted running of wind-cooled cold-water unit, produce certain blast, will be deposited on the dust that radiating fin etc. locates by blast and blow off, the air-flow that is formed by fan is taken out of again.
The utility model for achieving the above object, be achieved through the following technical solutions: comprise radiation fan, be connected with on the radiation fan and just changeing control circuit and reverse turn control circuit, just changeing control circuit is provided with and just changes control switch, reverse turn control circuit is provided with reverse control switch, just changeing control switch and be connected with on-off controller by lead respectively with reverse control switch, on-off controller is connected with total control circuit by lead.Delay controller is installed on the on-off controller, is just being changeed control switch and be connected with delay controller by lead respectively with reverse control switch.
Advantage of the present utility model is: reasonable in design; can make the radiation fan timing inverted running of wind-cooled cold-water unit; produce certain blast; to be deposited on the dust that radiating fin etc. locates by blast blows off; the air-flow that is formed by fan is taken out of again; can significantly reduce handpiece Water Chilling Units and shut down wash number, guarantee refrigerating efficiency, save human and material resources.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Wind-cooled cold-water unit fan blowback dust removal apparatus described in the utility model comprises radiation fan 1, be connected with on the radiation fan 1 and just change control circuit 2 and reverse turn control circuit 3, just changeing control circuit 2 is provided with and just changes control switch 4, reverse turn control circuit 3 is provided with reverse control switch 5, just changeing control switch 4 and be connected with on-off controller 6 by lead respectively with reverse control switch 5, on-off controller 6 is connected with total control circuit 7 by lead.Just changeing control switch 4 closures during normal the use, reverse control switch 5 disconnects, and is just changeing control circuit 2 conductings, and radiation fan 1 is just changeing, and is the handpiece Water Chilling Units heat radiation; After the work certain hour, total control circuit 7 sends the commutation instruction to on-off controller 6, on-off controller 6 makes just changes control switch 4 disconnections, reverse control switch 5 closures, reverse turn control circuit 3 conductings, radiation fan 1 counter-rotating makes and produces certain blast in the handpiece Water Chilling Units, will be deposited on the dust that radiating fin etc. locates by blast and blow off; Behind the blowback certain hour, total control circuit 7 sends reset instruction to on-off controller 6, and on-off controller 6 disconnects reverse control switch 5, is just changeing control switch 4 closures, is just changeing control circuit 2 conducting again, and radiation fan 1 recovers just changeing state.
In order to prevent that radiation fan described in the utility model 1 commutation is too fast and cause damage, delay controller 8 can be installed on on-off controller 6, just changeing control switch 4 and be connected with delay controller 8 by lead respectively with reverse control switch 5.When total control circuit 7 sends when instruction commutation to on-off controller 6, on-off controller 6 makes and just changes control switch 4 and disconnect, and delay controller 8 is closed again after making reverse control switch 5 postpone a period of times; When total control circuit 7 when on-off controller 6 sends reset instruction, on-off controller 6 disconnects reverse control switch 5, delay controller 8 is closed again after making and just changeing control switch 4 and postpone a period of times.Adopt the effect of said structure to be: radiation fan 1 stops operating earlier when commutation, again to opposite spin, avoids taking place because of the too fast situation that radiation fan 1 is damaged that commutates.
