Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saucer device in a filter press, and more particularly to a saucer device in a filter press incorporated into a narrow space around a filter plate array and driven to open and close.

[0002]

2. Description of the Related Art Conventionally, a pair of trays on the left and right sides are connected to a rotating shaft in a space below a filter plate row on a floor surface where a filter press is installed. It is known that it is constructed so as to have an approximately inverted V shape (Japanese Utility Model Publication No. 45-455). Also, one ends of the two trays are connected to each other so that they can be bent, and the rotation base of one saucer is pivotally supported on the abutment and the support of the other saucer is placed on a support rail. It is known that one of the trays is folded in two in accordance with the rotation of the one tray, and the other tray is pulled toward the outside of one side of the filter plate along the support rail by the one tray (actually, as shown in FIG. Kaihei 3-31370).

[0003]

In a device in which the pair of trays are connected to a rotary shaft to rotate below the filter plate row, the trays can be safely rotated in a space below the filter plate row to perform opening / closing operations. It is necessary to raise the filter plate from the floor so as to be possible, or to provide a considerably deep pit below the filter plate row. Therefore, the height of the filter press is increased by the operation of the tray, and the circumference of the filter press is also increased from the floor surface, which is inconvenient for work. Further, the pit is not always provided below the filter plate array. Also, in the case where two trays are connected in a bendable manner, one side of the filter board row must be opened as safe as possible when pulling the trays to one side of the filter board row. In addition, when pulling the tray below one side of the filter plate array, there must be a considerably deep pit below the filter plate array.

Therefore, in order to solve the above problems, the present invention does not increase the height of the main body of the filter press, and does not require a work floor surface around the filter plate row more than necessary, and is compactly incorporated in the main body of the filter press. It is an object of the present invention to provide a saucer device in a filter press that can be used.

[0005]

SUMMARY OF THE INVENTION The present invention is adapted to deploy below the filter plate row of a filter press to close the filter plate row bottom and to unclose the filter plate row bottom to open the filter plate row bottom. In a tray device that is driven to open and close, an outer rail portion that stands and supports the tray along the outside of the filter plate row, and an inner rail portion that deploys the tray at a closed position below the filter plate row and supports it in a closed posture, and the rail portions. A traveling path conversion rail for the saucer, which comprises an intermediate rail portion for changing the traveling posture of the saucer, and a traveling drive device for the saucer which is connected to the operation end of the saucer and causes the saucer to travel along the traveling path conversion rail. Be prepared.

[0006] Further, the trays are provided on both sides of the filter plate array, respectively, and at the closed position below the filter plate array, the leading end of the one tray and the other tray are connected to each other to be opened and closed. You may do it.

[0007]

When the traveling drive device for the tray is driven upward, the tray main body rises along the outer side of the filter plate row and is supported while standing on the outer rail portion of the traveling path converting rail. When the traveling drive device is driven in reverse, the tray body supported by the outer rail portion and in the standby position is turned from the standby position while the intermediate rail portion is descending and turned to the inner rail portion of the travel route conversion rail. It is inserted, deployed, and supported in a closed position.

[0008]

As described above, according to the present invention, when the tray is in the standby state, the tray main body is supported by the outer rail portion of the traveling path converting rail by the ascending drive of the traveling drive device so as to stand up along the outside of the filter plate row. When the filter plate row is deployed and closed, the tray main body is moved downward from the traveling drive device to the inner rail portion from the outer rail portion of the traveling path conversion rail to the inner rail portion when closed. It can be deployed in a closed position in the closed position below the row. Therefore, there is no need for a height space below the array of filter plates for rotating the tray or pulling it out in an inclined state. Further, since the tray can be housed along the outer side of the filter plate row, it is not necessary to open the work space around the filter press more than necessary. Also, there is no need to raise or expand the work scaffold around the filter press. In particular, this saucer device can be integrated with the filter press main body without expanding the framework of the filter press main body, and can be easily moved together with the filter press main body without taking the installation place of the filter press main body. There are many conveniences. Further, it can be installed and operated below the row of filter plates without requiring a pit.
