A liquid pipe 5 can be introduced between the furnace cloths 4 and 4 from above the furnace plate installation part.

The movable frame 6 has rollers 9a, 9. a,9h,. 9b is mounted on a pair of left and right mount guide rails 10 and 1 arranged parallel to the furnace plate guide rails 1 and 1 above the furnace plate installation part, so that the furnace plate can be moved freely in the Sekiiso direction. At the same time, this movable pedestal 6 is placed in the middle of a chain (not shown) installed along the pedestal guide rail 10,1 river.
The chains are connected each time the furnace plates 2 are opened one by one, and the chain is driven each time, and the movable frame 6 is moved in sequence so that the liquid pipe 5 is always at the intermediate position when the furnace plates 2, 2 are opened. I'm trying to move it.

The telescopic link-like supply pipe 7 pivotally connects one ends of two rigid tubes 11a and 11b oriented in the width direction of the movable frame 6 via a pair of elbows 12a and 12b, while the rigid tube 11
A fixed side supply pipe 13' fixed to the other end of a and the movable frame 6
One end disposed at the bottom of the movable frame is connected with Erubo 12c,
Further, the other end of the rigid tube 11b and one end of the liquid tube 5 oriented in the width direction of the movable frame 6 are pivotally connected by a pair of elbows 12d and 12e, and connected to the fixed side supply tube 13'. part, the connection part between the rigid tubes 11a and 11b, and the liquid pipe 5
The connecting portion with the flexural axis forms the axis of the bending and stretching movement.

The cleaning liquid supply source (not shown) that is installed at a location different from the movable frame 6 and that delivers the cleaning liquid and the fixed side supply pipe 13' are as follows:
The connection is made via a flexible tube (not shown) such as a rubber hose with sufficient slack so that movement of the movable frame 6 will not be hindered. The rumored liquid tube elevating means 8 is a movable pedestal 6
A pair of elevating bars 14, 14 are fitted with iron into guide sleeves 13, 13 installed on the left and right sides of the frame, and are movable up and down. A pinion 15 that meshes with racks 14a, 14a formed on one side of the bars 14, 14 facing the front side of the movable frame.
, 15, and a sprocket 16 installed on the movable frame 6,

, 15 and a motor 19 for rotationally driving the adjacent liquid pipe 5.
is horizontally supported between the lower end portions of lifting bars 14, 14, and vertical movement of the lifting bars 14, 14 in conjunction with the rotational drive of pinions 15, 15 causes the ejection tube 5 to be raised and lowered in a horizontal position.

A pair of pressure rollers 20 and 20 facing each other in the front and back direction are provided on the bottom plate 6a and the husband plate 6b of the movable pedestal 6, respectively, and the lifting bar is connected through the openings formed in the guide sleeves 13, 13. 14, 14 are supported by a pair of pinching rollers 20, 20 so that they can slide freely, and the vertical movement of each lifting bar 14, 14 with respect to the guide sleeves 13, 13 is prevented from rubbing against the guide sleeves 13, 13. We make sure it runs smoothly.

The engagement of the pinions 15, 15 with the racks 14a, 14a is also performed via the openings formed in the guide sleeves 13, 13. A plurality of nozzles 5a are provided on the circumferential surface of the liquid jet pipe 5 horizontally supported by the lift bars 14, 14, and are directed diagonally downward at the front and diagonally downward at the rear of the movable frame 6.
The cleaning liquid sent from the cleaning liquid supply source to the counterfeit liquid pipe 5 via the fixed side supply pipe 13' and the telescopic link-like supply pipe 7 is dispersedly emitted from each nozzle 5a... . This cleaning device operates as follows.

After the furnace is finished, 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 moving device (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 the furnace plate on the frame guide rails 10, 10. It moves in the opposite direction to the backward direction of step 2.

When the movable pedestal 6 moves to the point where the counterfeit liquid pipe 5 on the movable pedestal 6 is located in the area corresponding to the area between the separated furnace plates 2,
The movable pedestal 6 temporarily stops, and the motor 19 on the movable pedestal 6 starts to move the lifting bars 14, 14, which had kept the liquid pipe 5 waiting above the furnace plate when it was in the raised position. Drive down. The rotational output of the motor 19 is the subrocket 1
6. Pinion 1 via chain 17 and sprocket 18
Racks 14a, 14a of lifting bars 14, 14, with which the rotation of pinions 15, 15 meshes
is converted into a descending movement of the guide sleeve 1.
The lowering operation of the elevator bars 14, 14 is performed without rubbing against the inner walls of the elevators 3. As the lifting bars 14 and 14 descend, the telescopic link-like supply pipe 7 is connected to the fixed side supply pipe 13', the connection part between the Okayama body pipes 11a and 11b, and the liquid jet pipe 5.
The liquid pipe 5 is extended around the connecting portion as a pivot, allowing the liquid pipe 5 to descend.

On the other hand, as the elevating bars 14, 14 are lowered, that is, the liquid jet pipe 5 is introduced downwardly into the space between the furnace plates 2, 2, the fixed side supply pipe 13' and the telescopic link-shaped supply pipe 7 are connected to the fixed side supply pipe 13' from a cleaning liquid supply source (not shown). After that, the supply of cleaning liquid to the counterfeit liquid pipe 5 is started, and each nozzle 5 of the adjacent liquid pipe 5 is
A top cleaning process is performed from the upper side to the lower side of the furnace cloths 4, 4 by the cleaning liquid sprayed from a.

When the liquid pipe 5 reaches the lowermost level, the motor 19 is driven in reverse, the lifting bars 14, 14 change to an upward movement, and the liquid pipe 5 rises while continuing to spray cleaning liquid. When the adjacent liquid pipe 5 rises to the original standby position, the motor 19 is temporarily stopped, and the same operation as described above is repeated thereafter in conjunction with the next retraction operation of the furnace plate 2. When all the three door plates 2... are moved to the movable end plate side and the counterfeit liquid tube 5 moves up and down in the final cleaning process to complete the cleaning process, the movable frame drive motor is driven in reverse and the movable frame 6 is moved to the movable end plate side. When the movable frame 6 is returned to the initial position, it is stopped and the movable frame 6 is kept on standby at that position until the next cleaning.

According to the cleaning device of the present invention, a movable pedestal is arranged above the oven plate installation part so as to be movable in the direction of opening the oven plate, and a telescopic link-shaped supply attached to the movable pedestal is capable of bending in the vertical direction. The counterfeit liquid pipe is connected to the cleaning liquid supply source via a pipe, and the liquid pipe is supported so as to be able to rise and fall by means for raising and lowering the liquid pipe at the bottom of the movable stand, so that the ejection pipe can be raised and lowered using a telescopic link-like supply pipe. In addition, when the liquid pipe is in the standby state for rising, the telescopic link-like supply pipe bends and polymerizes and can be stored efficiently under the movable frame, making it possible to make the device more compact and reduce the furnace cloth. It can be installed with sufficient space without competing with other filter press accessories such as vibration devices, and the telescopic link-shaped supply pipe can be easily formed using rigid pipes such as ordinary steel pipes, and the structure is simple. It also becomes easier.

In particular, the elevating and lowering of the Akebono liquid pipe to advance and retreat between the opening furnace plates is achieved by reliable transmission of the elevating and lowering driving force by means of a pinion that engages with the rack portion in the guide sleeve of the elevating bar that is directly connected to both ends of the liquid pipe. Due to the engagement of the rack and pinion, the lifting bar is firmly held and guided by the pair of guide rollers so that it does not rub against the guide sleeve, and can move up and down, ensuring a well-balanced and smooth movement on the left and right sides. This has been achieved, and the injection pipe can be operated at a speed of, for example, 20k9/mm or more, without causing any deviation in vertical lift from left to right, the resulting twisting or damage of the lift bar support drive unit, or the inability to repeatedly lift/lower due to these. It is constantly moved up and down at a constant speed while receiving the injection reaction force, so that the entire area of the furnace material can be cleaned evenly and reliably.

In addition, the entire device is placed above the furnace plate installation section with plenty of space, so that the liquid jet pipe is introduced downward from above between the separated furnace plates, making installation even easier. The equipment does not get wet with processing agent cleaning solution during the cleaning process.
It is possible to effectively prevent equipment from being contaminated and corroded.
