Stream portion 32, be eventually returned to drip tray, it is to avoid sewage is blown on the inside of net during dry net cleaning, penetrates the water smoke of dry net with dirt
Thing can corrode deflector roll and other paper machine parts.In the present embodiment, the deflector roll 2 can be rotated around fixing axle, the deflector roll
On the one hand guide and the dry motion track netted of limitation, the current on the other hand cleaned to being ejected into dry net reflect, kept away
Exempt from sewage to enter dry net inner side and influence paper machine part.
In order to carry out lasting cleaning to dry net, the dry net cleaning device also includes drive mechanism, and the dry net 1 is driving
Under the active force of motivation structure, moved along deflector roll 2, i.e., constantly there is dry net 1 to move through the deflector roll 2, the cleaning head 3 is set
In the lower section of deflector roll 2, i.e., persistently cleaned using the mobile dry net 1 of 3 pairs of cleaning head.
In embodiments of the present invention, described device also includes crossbeam 5 and ring chain 4, and the crossbeam 5 is used to carry described
Cleaning head 3, the ring chain 4 drives length direction of the cleaning head 3 along deflector roll 2 to make under the driving of actuating unit
Move back and forth, the High-Pressure Water sprayed in nozzle 31 is cleaned the everywhere on dry net width, in the present embodiment
In, the inside of crossbeam 5 has the space for being used for installing ring chain 4, and the ring chain 4 is preferably tank chain.
In a preferred embodiment of the invention, the cleaning head 3 also includes Venturi tube 33, blow-off pipe 34 and air knife
35, referring to Fig. 2, the Venturi tube 33 is connected and connected with the rear end in backflow portion 32, and forming table is being impacted in set-point apart from liquid drugs injection
At 60mm positions, this special design of Venturi tube 33, which ensure that, makes the efficient suction of sewage backflow drip tray；The blowdown
Pipe 34 is connected and connected with the rear end of Venturi tube 33；The air knife 35 is arranged on the openend in backflow portion 32, for cleaning residual
Washmarking and spot on dry net 1, the quantity of the nozzle 31 can be one, preferably several, referring to Fig. 3, nozzle unit

Row or multiple rows of nozzle 31, the nozzle 31 spray High-Pressure Water to the regional of dry net 1 being close to deflector roll 2 simultaneously, by roll surface
The current being reflected back are returned in the backflow portion 32 of channel-shaped, drive cleaning head or so to move back and forth without tank chain.
Preferably same in the application to use the connected mode of Venturi tube 33, the principle of Venturi effect is then to work as to blow air over resistance
During block material, near ports air pressure is relatively low above the lee face of obstacle, so as to produce suction-operated and cause air
Flowing.The principle of Venturi tube is in fact very simple, it be exactly air-flow from the coarse to fine, to accelerate gas flow rate, make gas in Wen
One " vacuum " area of rear side formation of pipe outlet.Certain absorption can be produced when this region of no pressure is close to workpiece to workpiece to make
With.Referring to Fig. 3, the Venturi tube 33 relaxes structure afterwards first to shrink, it is preferable that in the lateral opening of the Venturi tube 33
The vacuum inputted in compressed air, the enhancing rear blow-off pipe 34 of Venturi tube 33, to further enhance the dirt to cleaning dry net 1
The suction force of water.
The dry network process of cleaning for the dry net cleaning device that the present invention is provided is as follows：High-pressure water pipe is connected, meanwhile, open cleaning
The air knife 35 of first 3 openend water, the nozzle 31 carries out injection High-Pressure Water to the dry net 1 at deflector roll 2, in the roll surface of deflector roll 2
Under reflex, sewage is returned in the backflow portion 32 of cleaning head 3, and the compressed air that air knife 35 is discharged on dry net 1 to remaining
Washmarking and spot are dried up, and are prevented into networking internal corrosion paper machine part；On the other hand, due to the vacuum of the generation of Venturi tube 33
Effect, makes the water for being back to the water in backflow portion 32 and being ejected on dry net 1 be eventually returned to blow-off pipe 34 under suction, or
Return to drip tray.
The dry net cleaning device of the present invention is connected with tracheae using high-pressure water pipe at support to cleaning head.Cleaning head is just right
Foul is smashed and rebounded with impact from roll surface in cleaning head by the wire side of deflector roll position, liquid drugs injection impact wire side.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
