Usually, the paper machine operating room is arranged on the second floor, the first floor is used for placing communicated pipelines and driving equipment, and therefore, a through hole is arranged on the roof of the first floor for a cable to pass through. The device provided in the embodiment is arranged in the through hole, the air duct 2 is fixed in the through hole, and the air duct 2 faces downwards.
The specific implementation process is as follows:
during the use, start fan 1, fan 1 is with the gaseous water conservancy diversion of lower part to the paper machine control chamber in for the paper machine control chamber keeps the malleation state, and then can reduce the dust that produces and piece when outside paper machine uses and get into inside volume through the gap of paper machine control chamber, thereby can reduce dust and piece and pile up the influence that causes air conditioner and the equipment operation in the paper machine control chamber in a large number, thereby prolong the life of equipment, reduce the maintenance frequency of air conditioner.
And when leading-in gas in the paper machine control chamber, gas can be inhaled through dryer 2 to pass air filter 7, filter gas through air filter 7, can further reduce the impurity volume that gets into inclusion in the gas in the paper machine control chamber, reduce the influence to air conditioner and the equipment in the paper machine control chamber.
After the positive wind device of paper machine control chamber used a period, can be mingled with a large amount of dust in the air filter 7 for reduce air filter's effect, and then lead to passing through the volume that air filter 7 flows and reduce, can influence and keep the malleation state in the paper machine control chamber. Therefore, the air filter element 7 needs to be cleaned, but the air duct 2 is arranged on the top of the first floor, so that the air filter element 7 is not easy to remove.
At this moment, grip the horizontal pole of carriage release lever 4 to drive 4 rebound of carriage release lever, because the rack of the bar inslot of montant meshes with 11 epaxial gears 12 of pivot, consequently can drive gear 12 through shifting up of rack and rotate, through the transmission of pivot 11, make fan 1 take place to rotate, thereby make the air inlet end and the air-out end of fan 1 take place to exchange, the air inlet end and the paper machine control chamber intercommunication of fan 1, the air-out end and the dryer 2 intercommunication of fan 1. And fan 1 rotates the back, can make second magnetism ring 13 on the air-out end relative with the first magnetism ring 21 at dryer 2 top, through inter attraction between first magnetism ring 21 and the second magnetism ring 13, realizes fixing fan 1. And in order to avoid fan 1 position to take place to remove, can set up the bracing piece and support the carriage release lever 4 tightly, avoid carriage release lever 4 to move down to can avoid fan 1 to take place to rotate.
When the movable rod 4 moves upwards to realize rotation of the fan 1, the rotating shaft 11 rotates, so that the pull rope 54 is wound, the pull rope 54 pulls the sliding rod 53 to move outwards of the fan barrel 2, the middle parts of the pressure increasing plates 5 move upwards through transmission of the driving rod 52, and the ends, close to each other, of the two pressure increasing plates 5 are gradually attached to each other. After the fan 1 rotates to the air outlet end and faces downwards, the straight side edges of the two pressurizing plates 5 are attached to each other and are spliced into a channel for air to flow through the notches 51 in the middle of the two pressurizing plates.
The fan 1 is restarted to lead the fan 1 to introduce gas into the air cylinder 2, and the axial flow fan 1 is used by the fan 1, so that a large amount of gas can be generated, but the flow rate of the gas is low, and the positive pressure use can be kept in a paper feeder operation room. And when leading-in gas in dryer 2, gaseous the blockking that receives pressure boost plate 5, only can flow through the passageway that forms between breach 51, and the accumulational gas is more in the dryer 2, consequently makes the velocity of flow of gas very fast, and reverse impact air filter 7 that can be quick for the adsorbed impurity on the air filter 7 shakes off, connects the dirt net through setting up in dryer 2 bottom, can collect the dust that shakes off.
And when air impacted air filter 7, can extrude air filter 7 to extrude the spring, and when air no longer impacted air filter 7, the extrusion force that air filter 7 received disappeared, and the spring can take place to reset, and then takes place vertical reciprocating motion, and then realizes the vertical reciprocating motion of air filter 7, can further shake the dust in the air filter 7 and fall. Thereby completing the cleaning of the air filter element 7.
Example 2:
The device is characterized by further comprising two push rods 9 penetrating through the limiting rings 61 at the tops respectively, the push rods 9 are connected with the limiting rings 61 in a vertical sliding mode, and limiting blocks 9 are fixed to the tops of the push rods 9. The bottom of the push rod 9 is abutted against the top of the air filter element 7, and the limit block 9 is abutted against the circular part of the cam 82.
The specific implementation process is as follows:
when the air is introduced into the paper machine operation chamber, the flow rate of the air is large but the pressure is small (the flow rate is slow) due to the operation principle of the axial flow fan 1, and therefore, there is no condition for rotating the rotary shaft 8 by hitting the rotary blade 81. And when leading-in gas in to dryer 2 through fan 1, setting through pressure boost plate 5 can make gas only flow from the passageway that two breach 51 formed, and then gaseous velocity of flow is very fast, when assaulting rotor blade 81, can make rotor blade 81 drive axis of rotation 8 and rotate to drive cam 82 and rotate, make the intermittent extrusion push rod 9 of bellying of cam 82, push rod 9 moves down, thereby extrusion air filter 7. When the cam 82 is rotated to not press the push rod 9, the air filter 7 is restored by the spring. Further, the air filter element 7 can continuously reciprocate, and dust attached to the inside of the air filter element 7 is vibrated down.
It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention, and these changes and modifications should not be construed as affecting the performance of the invention and its practical application.
