JPH0719527Y2 - Vibrating device for cloth in filter press - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a slag peeling device in a filter press, and more particularly to a device for peeling slag using the weight of a cloth and a spring.

[Conventional technology]

Conventionally, as a slag peeling device, two pairs of long and short links are connected to the front and back plates in a letter shape, a long hole is provided in the short link, and both ends of the cloth pulling down bar are slidably supported in this long hole. ,
A device that slidably attaches a detachable hook to the cloth pull-down bar along the long hole of the short link, and when the plate is opened, the hook is momentarily disengaged from the cloth pull-down bar and the cloth is vibrated to remove the slag. (For example, Japanese Utility Model No. 57-53605).

[Problems to be Solved by the Invention] In the above conventional device, the spring is contracted instantaneously when the spring is fully extended, so that an effective impact can be applied to the cloth, and a large peeling effect can be obtained. In addition, it does not require an expensive vibration device, but has a drawback that its structure is complicated.

[Means for Solving the Problems]

In order to overcome the above-mentioned drawbacks of the conventional device, the present invention is
When the board is opened, the cloth to which the slag adheres is momentarily dropped by its own weight, giving a shock to the cloth,
A spring that hangs the upper part of the cloth gives vibration to double the shock.

That is, the structure is a filter press in which a large number of plates are juxtaposed on a rail, and the upper end of the cloth is supported by springs erected on the upper part of the plate. And a guide pin on the top of this support and a guide pin near the lower part of the guide plate,
Providing an operation in which the lower end of the other plate is pivotally attached to the shoulder,
A long hole is bored in the upper part of this operation, and the guide pin of the above support and the long hole of the operation are slidably fitted, and when the plate is closed, the operation sets up the support so that the guide plate is set up. The guide bar is brought into contact with the cloth support bar, and when the plate is opened, the operation pulls the support to separate the guide plate from the cloth support bar.

〔Example〕

The embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numerals 1 and 1 are frames arranged in front and rear, and reference numeral 2 is a pair of rails bridged between frames 1.1. A large number of plates 3 ... Are arranged side by side in an openable and closable manner. As shown in FIG. 2, a guide rod 4.4 is erected on the shoulder portion of the plate 3, and a support bar 7 hung from the spring 5 and the upper end portion of the cloth 6 is inserted into the guide rod 4. The spring 5 supports the upper end portion of the stretched cloth 6 of 3. Reference numeral 8 is an adjustment nut for adjusting the tension position of the cloth 6. A support 9 pivotally attached to the lower end is provided at one shoulder of the front and rear plates 3.3, and a guide plate 10 is provided at the top of the support 9 and a guide pin 11 is provided near the lower part of the guide plate 10. . Actuation with the lower end pivotally attached to the shoulder of the other plate 3 12
Is provided, and an elongated hole 13 is bored in the upper portion of the operation 12. Further, the guide pin 11 of the support 9 and the elongated hole 12 of the operation 12 are slidably fitted together, and the support 9 and the operation 9
12 and 12 form a letter-shaped pantograph. And
When the plate 3 ... is closed, it is activated by the plate closing force.
The lower end of the long hole 13 provided in the upper part pushes up the guide pin 11 of the support 9, and the operation 12 is erected, and the inclined part provided at the tip of the guide plate 10 is below the support bar 7 of the cloth 6 from which the slag has been peeled The guide plate 10 is slidably supported on the support bar 7 by rotating the guide plate 10. Further, when the plates 3 ... Are opened, the upper end of the long hole 13 provided in the operation 12 pulls the guide pin 11 of the support 9 to rotate the support 9 in an inclined manner, so that the guide plate 10 is supported.
It is designed to dissociate from. That is, the support bar 7 is supported by the guide plate 10 and the cloth 6 in the over position is
When is removed from the support bar 7, the weight of the slag and the cloth 6 causes the spring 5 to instantaneously descend, and the spring 5 is rapidly compressed. Then, a strong repulsive force is generated at the lowermost end of the compression of the spring, violently vibrating the cloth to shake off the slag from the cloth 6.
The cloth 6 becomes lighter and pushed up by the spring 5 to return to the over position. In addition, reference numeral 14 is the plate 3
Hydraulic cylinder for opening and closing,…, numeral 15 is hydraulic cylinder
It is a movable head connected to 14.

[Effect of device]

The present invention is configured as described above, and when the plate is opened, the opening force of the plate causes the cloth to which the slag adheres to be instantaneously dropped, and the impact of the drop and the repulsive force of the spring to separate the slag from the cloth. You can That is, in the conventional device, the cloth slowly pulled down by the plate opening force was used to instantaneously pull up the cloth by the repulsive force of the spring to peel off the slag. Since the letter-shaped support and operation provided on the plate shoulder part are designed to release the support bar of the cloth by the plate opening force of the plate and cause the cloth to drop momentarily, there is a drop due to gravity and a rise due to repulsive force. The impact is applied twice as much as that of (3), and the slag can be reliably peeled off with a simple structure.
