I'm trying to rotate it.

On the peripheral surface of the spray pipe 50, the nozzles 5a, which are stopped and directed in the front-rear direction of the movable frame 6, are separated, and the cleaning liquid sent from the cleaning liquid supply source to the spray pipe 5 via the liquid supply pipe 11 is supplied to the nozzle. 5
a...The injection is more dispersed.

This cleaning device operates as follows.

After the filtration is completed, the movable end plate that was pressing the furnace plate 2 between it and the fixed end plate retreats, and the furnace plate 2 is moved to the movable end plate side by a furnace plate transfer mechanism (not shown). will be transferred to.

The backward motion of each furnace plate 2 is detected by a detection element such as a limit switch, and in response to the detection signal, a movable frame drive motor (not shown) is sequentially activated, and the movable frame 6 moves on the frame guide rails 15, 15 to move the furnace plate. It moves in the opposite direction to the backward direction in step 2.

At this time, the jet tube feed stand 7 is on standby at one end of the movable stand 6, while the hinge arm 8 has its end arm 8a in the first position.
At the near rotation position where the upward position shown in the figure is reached, the arm stopper 10 hits the arm 8a, and the liquid jet tube 5 is prevented from rotating toward the hanging position due to its own weight, so that it is tilted slightly downward from horizontal. It is waiting in an upper position where it does not interfere with the Fffi 2 and the furnace cloth 4.

When the movable pedestal 6 moves to the point where the liquid jet pipe 5 is located between the separated furnace plates 2, 2, the movable pedestal 6 temporarily stops, and then the arm driving means 12 is started and the hinge arm 8 is moved. begins to rotate counterclockwise in FIG.

As the arm 8a rotates, the liquid jet tube 5 gradually shifts to a hanging position, and when it reaches the hanging position shown at 5' in FIG. When the hinge arm 8 reaches the rotational position facing , the hinge arm 8 stops. At this time, the liquid jet pipe 5 is at the position indicated by 5'' in FIG.

As the liquid jet pipe 5 shifts to the hanging position, supply of cleaning liquid from the cleaning liquid supply source to the liquid jet pipe 5 via the liquid supply pipe 11 is started.

Then, the feeder drive means 20 is activated, and the jet tube feeder 7 begins to move from the standby position toward the other end of the movable pedestal 6, causing each nozzle 5a of the jet tube 5 to proceed in a hanging position.・・・
The cleaning process is performed sequentially from one side of the furnace cloth 4 to the other side with the cleaning liquid sprayed from. The liquid jet pipe 5 is the fourth
Move the furnace cloth 4 as shown by 5'' to 5'' in the figure.
When the other side is reached, the motor 23 of the feed table moving means 20 is driven in the reverse direction, and the jet tube feed table 7 turns to move in the opposite direction.0 When the jet tube feed table 7 returns to its original standby position. When the feeding platform moving means 20 stops driving, the supply of cleaning liquid to the jet pipe 5 is also stopped.

Then, the motor 28 of the arm driving means 12 starts to drive in the opposite direction to the initial direction, and the arm 8a of the hinge arm 8 begins to rotate clockwise in FIG. The arm 8 is placed in a rotation position where rotation of the liquid pipe 5 toward the hanging position due to its own weight is prevented.
When point a is reached, the liquid jet pipe 5 returns to its original standby position, retracted from the furnace plate 2 and furnace cloth 4, following the reverse course of the previous introduction operation.

When the jet pipe 5 returns to its original standby position, the motor 28 of the arm drive means 12 is temporarily stopped, and the same operation as described above is repeated thereafter in conjunction with the next backward movement of the furnace plate 2.

All the F plates 2... are moved to the movable end plate side, and in the final cleaning process, the jet pipe 5 performs a reciprocating operation of introducing and retracting between the furnace cloths 4, 4, and when the cleaning process is completed, it is moved. When the gantry drive motor drives in reverse and returns the movable gantry 6 to the initial position, it stops, and the movable gantry 6 is kept on standby at that position until the next cleaning.

According to the cleaning device of the present invention, the first
．． The hinge arm mechanism having the second arm is connected to the first arm so that both arms can rotate in a plane parallel to the furnace plate surface.
The arm stopper is attached to the liquid jet pipe feeding means on the non-connecting end side of the arm, and restricts rotation of the second arm relative to the first arm when the first arm is in a rotation range exceeding a predetermined upward rotation position. Then, the cleaning liquid supply source connection end side of the rigid liquid jet pipe connected to the cleaning liquid supply source is connected to the second arm, and the liquid jet pipe is retracted above the door plate installation part as the hinge arm mechanism rotates. Since the posture is changed from the posture to the hanging posture, the following effects can be obtained.

(a) With the jet tube feeding means stopped at the standby position,
In addition to being able to introduce and evacuate the liquid jet pipe between the boards,
Since the injection tube is introduced and retracted by a combination of rotation and lifting motion by the hinge arm mechanism, there is no need to set an extra travel stroke of the ejection tube delivery means for introducing and retracting the injection tube. , the device can be made compact.

(B)! , the liquid jet pipe can be placed on standby in a slightly downwardly inclined position by utilizing the space above the furnace plate installation part, so even if the liquid jet pipe is quite long, its tip will touch the furnace plate in the standby state. It can be efficiently accommodated without protruding in the width direction of the installation part, and when there is competition for installation space with other filter press accessories such as furnace cloth vibrators, it can be installed with sufficient margin, and the structure is also It gets easier.

(c) Since the entire device can be placed above the furnace plate installation area where there is plenty of space, the device will not be covered with treated cleaning fluid, preventing staining and corrosion of the device, and making installation even easier. .
