The cross section of the dental plate 1409 is of a structure of a fish with a shade and a sun, and the heads of the eight dental plates 1409 are rotationally arranged in the anticlockwise direction, so that different effects on the cleaning roller 1308 are realized through different rotation directions of the dental plates 1409.
The working principle of the invention is as follows:
when needs carry out heat recovery to waste gas and utilize, make 8 intake-air pipes inhales waste gas through starting axial fan 5, waste gas purifies the back through purifying box 7, pass through in second connecting pipe 6 and the first connecting pipe 4 get into heat exchanger 1 again, make waste gas can get into in the intake pipe 8 through third connecting pipe 10 again through opening second control valve 9, through first connecting pipe 4, second connecting pipe 6, the airflow channel of third connecting pipe 10 and 8 formation of intake pipe, can realize the loop filter of waste gas and heat exchanger 1 and recycle the thermal high-efficient recovery of used heat air, can reduce steam consumption, reach and reduce the energy consumption, reach the mesh of energy saving.
When waste gas gets into in the filter tank 1101, the preliminary interception of fibre hair in the waste gas through filtration pore 1103, can play prefiltration's effect to waste gas, when waste gas gets into working chamber 1102, the tertiary filtration through filter 1105 can carry out multiple filtration to the fibre hair in the waste gas, can absorb the fluid in the waste gas through oil absorption filter cloth 1106, thereby the guarantee gets into the waste gas in the heat exchanger 1 and can not produce the negative effect, when filter 1105 and oil absorption filter cloth 1106 became invalid, the staff can open the sealed lid 1108 in manhole 1107, take out filter 1105 and oil absorption filter cloth 1106 from pull track 1104 and change, still be convenient for clear up working chamber 1102 and filter tank 1101.
When steam generator 1201 starts, steam can enter into in the removal pipe 1205 through connecting flexible pipe 1206, the first shower nozzle 1208 of rethread upwards sprays away, at this moment, utilize the produced effort of spraying steam to make removal pipe 1205 drive movable block 1209 extension coupling spring 1204, make movable block 1209 move up and down on first dead lever 1202, when making first shower nozzle 1208 spray steam move down, can clear up the filter 1105, and when first shower nozzle 1208 removed to the lowest, the steam of upwards flowing can carry out the heat energy to the waste gas of flowing through and mix, the heat that is favorable to steam also is absorbed by heat exchanger 1, and can also humidify the fibre hair in the waste gas, thereby can improve the filter effect of filter 1105 to the fibre hair.
When the moving pipe 1205 moves downwards, the moving pipe 1205 drives the moving block 1209 to compress the extrusion air bag 1301 in the downward movement process, gas in the extrusion air bag 1301 can enter the pressurization air bag 1305 through the connecting pipe 1306, the moving plate 1303 can move upwards on the second fixing rod 1302 along with the increase of the volume of the pressurization air bag 1305, when the moving pipe 1205 resets, the moving plate 1303 can reset downwards under the action of self gravity, and the moving plate 1303 can drive the cleaning roller 1308 to roll on the filter plate 1105 in the movement process, so that the adhesive on the cleaning roller 1308 can clean fiber hairs attached to the filter plate 1105.
When the fixed block 1307 drives the cleaning roller 1308 to move upwards along the filter plate 1105, the cleaning roller 1308 rotates along the needle, and meanwhile, the cleaning roller 1308 can drive the driving wheel 1403 to rotate synchronously through the first rotating shaft 1401 in the rotating process, so that the driving wheel 1403 can drive the driven wheel 1406 to rotate clockwise through the driving belt 1407, thereby enabling the rotating column 1408 to drive the dental plate 1409 to rotate clockwise, so that the dental plate 1409 can extrude the surface of the cleaning roller 1308, which is beneficial to the seepage of the adhesive on the surface of the cleaning roller 1308, when the fixed block 1307 drives the cleaning roller 1308 to move downwards along the filter plate 1105, the cleaning roller 1308 rotates anticlockwise, at this moment, the rotating column 1408 drives the dental plate 1409 to rotate anticlockwise, so that the dental plate 1409 can scrape the fiber hairs on the surface of the cleaning roller, and the continuous use effect of the cleaning roller 1308 is ensured.
