Technical problem is solved through following technical scheme:

the utility model provides a high-voltage inverter filter screen cleaning device, includes pulse air chamber, clean room and ash collecting chamber, pulse air chamber top is equipped with the pulse valve, the clean room is connected to pulse air chamber bottom, sets up the round layer board on the inner wall of clean room, is equipped with on the clean room lateral wall and gets and put the mouth, and the clean room bottom is equipped with the ash collecting chamber, and ash collecting chamber one side sets up the gas outlet, and the bottom is equipped with the unloading valve.

Above-mentioned high-voltage inverter filter screen cleaning device, the pulse air chamber bottom is equipped with the flow equalizing plate, the equipartition has the gas pocket on the flow equalizing plate.

Above-mentioned high-voltage inverter filter screen cleaning device adds the suction pipeline, the gas outlet cladding is in the suction pipeline, the unloading valve exposes outside the suction pipeline. The suction pipeline is provided with a wind port, the wind port is provided with a dust removal plate, and the wind port is externally connected with a draught fan.

Above-mentioned high-voltage inverter filter screen cleaning device, the pipeline front end of pulse valve sets up the nitrogen gas valve.

The utility model has the advantages of it is following:

the utility model discloses a set up the pulse air chamber and blow towards the filter screen, set up the fixed filter screen of clean room, utilize the pulse valve to blow towards nitrogen gas to the filter screen to clean the filter screen, the pulse valve bottom is equipped with flow equalizing plate, flow equalizing plate makes nitrogen gas to the filter screen sweep the non-blind area, clean thoroughly; the utility model discloses set up the gas outlet on one side of the ash collecting chamber, the outside of gas outlet sets up inhales the pipeline of taking out, inhales the pipeline of taking out and filters the back to the gas outlet combustion gas, discharges in the atmosphere, prevents secondary pollution.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the drawings, the respective reference numerals denote: 1. nitrogen valve, 2, pulse valve, 3, pulse air chamber, 4, flow equalizing plate, 5, air hole, 6, filter screen, 7, support plate, 8, dust removing chamber, 9, taking and placing port, 10, air outlet, 11, dust collecting chamber, 12, dust discharging valve, 13, suction pipeline, 14, draught fan, 15 and air port.

Detailed Description

Referring to the attached drawing 1, the utility model discloses a pulse air chamber 3, clean room 8 and

dust collecting chamber

11, 3 tops of pulse air chamber are equipped with pulse valve 2, the clean room 8 is connected to pulse air chamber 3 bottoms, set up round layer board 7 on the inner wall of clean room 8, are equipped with on the 8 lateral walls of clean room and get and put mouth 9, and clean room 8 bottom is equipped with dust collecting chamber 11, and dust collecting chamber 11 one side sets up gas outlet 10, and the bottom is equipped with unloads grey valve 12. Get and put mouth 9 and layer board 7 on same horizontal position, when filter screen 6 needs to wash, open and get and put mouth 9, put filter screen 6 into clean room 8 along layer board 7 level, close and get and put mouth 9. And then opening the nitrogen valve 1 at the front end of the pulse valve 2 and the front end of the pulse valve 2, purging the filter screen 6 by using nitrogen, collecting the purged dust in the dust collection chamber 11, and discharging the nitrogen from the gas outlet 10.
