Description

DETAILED DESCRIPTION OF THE INVENTION This invention applies vibration to a furnace cloth hanging rod installed horizontally at right angles to the opening direction of the hanging furnace plate, and the furnace cloth suspended from the furnace cloth hanging rod. The present invention relates to a cloth vibrating device for a filter press that is configured to oscillate.

As a conventional example of a furnace cloth vibrating device for this type of filter press, the vibrating head is lowered to a position where it can act on the furnace cloth hanging rod, and then the vibrating head is driven forward and backward, so that the furnace cloth is moved by the action of the corrugated portion at the lower end of the vibrating head. (Japanese Patent Publication No. 54-1962) or transmits the rotational movement of the crank mechanism to the vibrating head, giving circular motion to the vibrating head located at a position where it can act on the furnace cloth hanging rod. The thing that swings the hearth cloth (Hakama Kosho 5)
No. 4-24747) are known.

However, in a configuration in which the furnace cloth suspension rod is swung by the corrugated portion at the lower end of the vibrating head, there is an operational problem in that the furnace cloth is easily damaged because the furnace cloth is rubbed by the sliding action of the vibrating head. Since the vibration head supported by the head mount is moved back and forth by moving the support base forward and backward using a crank mechanism, the head mount is driven in addition to the vibration head, and there is no extra drive required. In addition to consuming large amounts of energy, this method also requires a support structure to support the head mounting base in a reciprocating manner, which poses problems in terms of driving energy burden and structure.

Furthermore, since the vibrating head elevating means for elevating and lowering the vibrating head is attached to the head mounting base, the load of the head elevating means is also added, further increasing the burden of driving energy. On the other hand, in the configuration example that gives a circular motion to the vibrating head, although there is no operational problem like the above configuration example, the head mounting base supporting the vibrating head rotates together with the vibrating head via a crank mechanism. The structure to be driven and the point that the vibrating head elevating means is attached to the head mount are the same as in the above configuration example, and similarly there is a problem in that the burden of driving energy increases.

The purpose of this invention is to provide a filter press oven cloth vibrator which can solve the above-mentioned drawbacks of the conventional filter press oven cloth vibrator and which can reduce the burden of driving energy without damaging the oven cloth. It is something to do.

A similar mechanism is provided at the other end of the movable base 7 to connect both ends of the furnace cloth hanging rod 5 to a pair of vibrating heads 9,
I'm trying to make it oscillate at 9.

The motor constituting the vibrating head drive means 14 is commonly used to drive the pair of vibrating heads 9, 9. The operation of this oven cloth vibrator will be explained next.

When the filter press has completed the squeezing process and the furnace plates 2, 2 are in an open state as shown in FIG. Move to.

Then, the pressurized air supply means (not shown) starts driving, and the piston rod 10a of the air cylinder constituting the mount lifting means 10 retreats from the initial extended state and moves the cranks 11, 11', 11'' downward. As a result of this operation, the head mounting base 8, which was located above as shown by the imaginary line in FIG. When the motor constituting the vibrating head drive means 14 starts driving in the above-mentioned state where the head mount 8 is lowered,
The rotational output of this motor is applied to sprocket 2 as mentioned above.

A circular motion with a radius corresponding to the arm length of 0c is performed.

Due to the circular motion of the vibrating head 9, the furnace cloth hanging rod 5 supporting the lower side of the head portion 9c vibrates back and forth and up and down against the coil spring 4, and with this movement, the furnace cloth 6 is caused to swing and vibrate. A straddling action occurs, and the oven slag adhering to the oven cloth 6 is effectively brushed off.

In this embodiment, the head mounting base 8 is moved up and down by swinging one of the cranks 11, 11', and 11'' constituting the first parallel crank mechanism using a air cylinder. In addition, as in another embodiment shown in FIG. 4, the head mount 8' is supported by a moving base (not shown) via a crank mechanism 29', and the crank of the crank mechanism 29' serves as a means for raising and lowering the mount. A configuration may also be adopted in which a motor that rotationally drives the axle 30 is used to move the head mount 8' up and down by linear movement guided by guides 32, 32 of a piston rod 8'a pivotally connected to the connecting rod 31.

In this case, the rotational output of the vibrating head drive means consisting of a motor is transmitted between the chain 34 that is stretched between the crank axle 30 and the crank pin 33 → the crank pin 33 → and the connecting rod/piston rod pivot pin 35. chain 3
6→The vibration can be transmitted to the parallel crank mechanism for rotating the vibration head in the order of the chain 38 stretched between the pivot pin 35 and the head mount support shaft 37. Each chain 34, 36, 38 has a sprocket 38', 39, 40, 41 which is pivoted on the crank axle 30, crank pin 33, pivot pin 35, and head mount support shaft 37, respectively.
, 42, 43. Each crank 20 constituting a crank mechanism that gives circular motion to the vibrating head 9' is
0b', 20c' and the chain mechanism for rotating them together are the same as in the previous embodiment. As described above, the furnace cloth vibrating device of the present invention supports the head mounting base so as to be movable up and down via the crank mechanism with respect to the movable base that can move forward and backward in the opening direction of the furnace plate, and The vibrating head is supported via a parallel crank mechanism so as to be rotatable within a predetermined vertical plane parallel to the opening direction of the furnace plate, while the crank shaft/crank pin of the crank mechanism supporting the head mounting base and the vibrating head are The rotational output of the vibrating head drive means on the movable base side is transmitted to the parallel crank mechanism through an endless band transmission mechanism that spans between the drive shafts of the supported parallel crank mechanism, and the vibration is generated independently of the head supporting base. Since it is configured so that rotational motion is applied only to the head, the following effects can be obtained. The vibration head is not rotated together with the head mounting base, but the head mounting base is stopped and only the vibration head is operated, so the load is reduced and the vibration motion is reduced. The required energy can be saved, and the drive source and drive transmission means can be made smaller accordingly, making the overall structure more compact.

'. ) To move the vibrating head up and down to a position where it can act on the furnace cloth hanging rod, instead of attaching a head lifting means to the head support stand as in the conventional example, the head support stand is supported on a movable base. Since the vibrating head is indirectly raised and lowered by driving the crank mechanism, there is no need for a direct lifting means on the head mount, eliminating the need for a lifting guide member for the vibrating head, and the head mount is also smaller. can. The rotational drive of the vibrating head is achieved by transmitting the rotational output of the vibrating head drive means installed on the movable base side through the crank axis and crank pin of the crank mechanism that supports the head mounting base, and then to the parallel crank mechanism for supporting the vibrating head. Since the transmission is transmitted to the parallel crank mechanism using an inorganic band transmission mechanism that spans the drive shaft, each fin of the crank mechanism can be used as the rotating shaft of the endless band transmission mechanism, simplifying the structure of the transmission mechanism. can be converted into

9 The vibrating head is supported by a parallel crank mechanism, which provides sufficient support strength, and its circular motion swings the furnace cloth hanging rod, so the sliding action of the vibrating head against the furnace cloth hanging rod is effective. There is no damage to the furnace cloth.

In this example, the parallel crank mechanism that supports the head mount has a V-shaped three-point support structure.
The vibrating head can be supported stably.

H In addition, in the first embodiment, each crank axle of three sets of cranks of a parallel crank mechanism that supports a vibrating head on a head mount, and three sets of cranks of a parallel crank mechanism that supports a head mount on a movable base. Since the same shaft is used as the crank pin, the support structure can be greatly simplified.
