The utility model discloses in technical features such as controller, pressure sensor, oil water separator, dust processor and amortization filter (the utility model discloses a component unit/component), if do not have special explanation, all obtain from conventional commercial approach, or make with conventional method, its concrete structure, theory of operation and the control mode that probably involves, spatial arrangement mode adopt the conventional selection in this field can, should not be regarded as the utility model discloses an innovation point is located, to the technical staff in this field, can understand, the utility model discloses a do not further specifically expand the detailing.
An air generator having a pretreatment device according to the present invention will be described in detail with reference to fig. 1.
Example 1:
referring to fig. 1, an air generator with a pretreatment device comprises a generator body 1 and a controller 2 which are electrically connected, wherein the generator body 1 comprises a compressor 11 and an air storage tank 12 which are communicated, the generator body 1 is communicated with the pretreatment device 3, and the pretreatment device 3 comprises an oil-water separator 33, a dust processor 32 and a silencing filter 31 which are sequentially communicated with an input port of the compressor 11.
Further, in another embodiment, a first electromagnetic valve 41 communicated with an output port of the compressor 11 is further included; the first solenoid valve 41 includes a first flow passage 401 communicating with the atmosphere, and a second flow passage 402 communicating with the air tank 12.
Further, in another embodiment, the device further includes a check valve 5 having one end communicating with the second flow passage 402 of the first solenoid valve 41 and the other end communicating with the input port of the air storage tank 12.
Further, in another embodiment, the bottom of the air storage tank 12 is further communicated with a second electromagnetic valve 42, and an outlet of the second electromagnetic valve 42 is connected with a water outlet pipe to discharge accumulated water in the air storage tank 12 to a sewer.
Further, in another embodiment, the controller 2 is electrically connected to the operation switches of the compressor 11, the first solenoid valve 41 and the second solenoid valve 42, respectively.
Further, in another embodiment, the output port of the air storage tank 12 is communicated with a pressure reducing valve 6.
Further, in another embodiment, a pressure sensor (not shown) is installed in the air storage tank 12, and the pressure sensor is electrically connected to the controller 2.
The utility model discloses a theory of operation of an embodiment as follows:
after the air generator of the utility model is powered on, when the air pressure in the air storage tank 12 is smaller than the set lower limit value, the pressure sensor transmits the signal to the controller 2, and after processing, the second flow passage 402 is controlled to be closed and the first flow passage 401 is controlled to be opened, so that the compressor 11 is connected with the atmosphere; then the compressor 11 is started at normal pressure, the first flow channel 401 is controlled to be closed, the second flow channel 402 is opened, the indoor air is firstly processed by the silencing filter 31, the dust processor 32 and the oil-water separator 33 in sequence, then is compressed by the compressor 11 and then enters the air storage tank 12 through the one-way valve 5, when the air pressure in the air storage tank 12 reaches a set upper limit value, the pressure sensor transmits the signal to the controller 2, after the processing, the compressor 11 is controlled to be closed, and the one-way valve 5 can prevent the air in the air storage tank 12 from flowing back.
The air can rise through compressor 11 compression back temperature, when getting into gas holder 12, because the temperature difference can condense and form ponding in the 12 bottoms of gas holder, consequently, when compressor 11 started, the steerable second solenoid valve 42 of controller 2 was opened and only needs the ponding discharge of 0.2 seconds with the 12 bottoms of gas holder, and wherein the time that second solenoid valve 42 was opened is that reachs through the repetition test, and 0.2 seconds just can be with the ponding discharge of gas holder 12 bottoms. Therefore, accumulated water in the air storage tank 12 can be discharged before the compressor 11 supplies air to the air storage tank 12, and air supply of the compressor 11 to the air storage tank 12 is not affected.
