Description

DETAILED DESCRIPTION OF THE INVENTION This invention applies vibration to a furnace cloth hanging rod, which is grooved in a direction perpendicular to the opening direction of a suspended furnace plate, through a spring. This invention relates to a filter press furnace cloth vibrating device that shakes off furnace pores attached to the furnace cloth by sowing the furnace cloth.

As a conventional example of this kind of filter press furnace cloth vibrating device, the vibrating head is lowered to a position where it comes into technical contact with the furnace cloth hanging twills, and then the vibrating head is moved forward and backward, and the waveforms at the lower end of the vibrating head act to move the vibrating head into the furnace. A device that oscillates the cloth (Samurai Kosho No. 54-19622) transmits the rotational motion of a crank to the vibrating head, which gives a circular motion to the vibrating head that is in direct contact with the furnace cloth hanging rod, thereby causing the furnace to move. Something that swings cloth (Taru Kosho 54-12474
No. 7) are known.

However, the position where the vibrating head acts on the furnace cloth suspension rod must be placed outside the hanging rod support spring, which not only requires an excessive amount of space on both sides of the furnace plate, but also requires space on both sides of the base of the counterfeit. It is uneconomical in terms of installation space and structure, as it requires a configuration in which the units are connected by a parallel rail to the furnace cloth hanger, and a pair of left and right mechanical parts, including the motor.

In addition, in a configuration that gives circular motion to the vibrating head, the direction change operation is slow in the reciprocating cycle of the vibrating head, so
The disadvantage is that the impact applied to the furnace cloth hanging rod is weak and the swinging effect of the furnace cloth is not sufficient.

The present invention aims to solve the above-mentioned drawbacks of the conventional filter press oven cloth vibrator, and to provide a filter press oven cloth vibrator that can perform sufficient oven cloth vibration without damaging the oven cloth. This is the purpose. Hereinafter, an embodiment of the furnace cloth vibration device of the filter press of the present invention will be described based on the drawings.A plurality of furnace liquids are supported between a pair of left and right furnace plate guide rails (not shown) in a freely sliding manner, and As shown in Figure 2, there are projecting arches at both ends of the upper part of each furnace plate.
In the filter brace, a furnace cloth hanging rod 3 is suspended between the arms 1, 1 via coil springs 2, 2, and a furnace cloth 4 suspended from the furnace cloth hanging rod 3 is sandwiched between each furnace plate. This oven cloth vibrating device is configured to apply vibration to the oven cloth hanging rod 3 and swing the oven cloth 4, and includes a movable base 5 that can move forward and backward in the opening direction of the furnace plate, and a movable base 5. A head mount 6 is provided and is movable in the opening direction of the furnace plate; a vibrating head 7 is provided on the head mount 6 so as to be movable up and down and presses against the furnace cloth hanging twill 3 at a predetermined lowering position; and a movable base 5. A first air sill 8 is provided on the head mount 6 to move the head mount 6 forward and backward, and a second air sill 8 is provided on the head mount 6 and drives the vibrating head 7 up and down.
The vibrating head 7 is made to move up and down in a zigzag pattern by the joint action of the first and second air cylinders 8.9.

The movable base 5 is in the shape of a rectangular parallelepiped frame, and a pair of left and right base guide rails 10, 10 made of channel steel are arranged squarely with the furnace plate guide rail of the filter press above the furnace cloth hanging rod 3.
Guide rollers 11, 11 whose upper and lower surfaces are pivotally connected to the upper and lower front and rear sides of both sides of the movable base 5, respectively.
The pair of chain conveyors 2 and 12 are sandwiched between the base gadrails 1 and can be slid freely in the opening direction of the oven plate.
The movable base 5 is installed in the middle of the chain conveyors 12, 12 via connection pieces 13, 13 provided along the sides of the movable base 5 and protruding from both sides of the movable base 5, and the chain conveyor is connected by a motor (not shown). 12, 12 are reciprocated to move the movable base 5 forward and backward in the opening direction of the furnace plate.

As shown in FIG. 3, the head mounting base 6 consists of a pair of front and rear horizontal frames 14a, 14b and a cylinder mounting seat 15 that connects the machine frames 14a, 14b. The guide sleeves 17 provided at both ends of each frame frame 14a, 14b are slidably inserted into the pair of left and right guide shafts 16, 16 constructed, while the movable base 5 is A piston rod 18 of a first air cylinder 8 provided on the front side is connected to the front end of the head mounting base 6.

The second air cylinder 9 is vertically installed on the cylinder mounting seat 15 of the head mounting base 6 with its piston rod 20 facing downward, and the vibrating head 7 connected to the piston rod 20 is placed below the furnace cloth. It is designed to move up and down toward the hanging rod 3.

A pair of guide shafts 21 are further provided at the upper end of the vibrating head 7.
, 21 are installed vertically, and the guide shafts 21, 21 are inserted through the front and rear horizontal frames 14a, 14b of the head mounting base 6.
, 22 so that the vibrating head 7 can be smoothly moved up and down with respect to the head mounting base 6. The pressurized air supply V supply pipe 23 connected to the first and second air cylinders 8 and 9 is provided with sufficient slack to allow movement of the movable base 5, as shown in FIG. Base guide rail 10,1
It is located above 0.

In this embodiment, the first air cylinder 8, the second air cylinder 8, Solenoid valves 24 and 25 that control air supply to 9
The opening/closing cycle is set so that the vibrating head 7 performs a zigzag movement back and forth a plurality of times in one descending process.

The operation of this oven cloth vibrator will be described in detail below with reference to FIGS. 5A and 5B.

When the filter press has finished the squeezing process and the furnace plate and furnace cloth 4 are in a retracted state, the chain conveyors 12, 1
2 is driven to move the movable base 5 onto the furnace cloth 4.

Next, the solenoid valves 24 and 25 that control the supply of pressurized air to the first and second air cylinders 8 and 9 start driving, and the head mounting base 6 is moved forward and backward by the first air cylinder 8. The vibration head 7 moves up and down in a zigzag pattern within a predetermined vertical plane perpendicular to the oven cloth hanging rod 3 by a combination of the driving and the raising and lowering driving by the second air cylinder 9. That is, the lowering process of the vibrating head 7 by the second air sill 9 (arrow mark P in Fig. 5A)
, ), the movement of the head mounting base 6 by the first air cylinder 8 is advanced and retreated (indicated by arrows P2 and P2' in FIG. 5A).
) is performed in a complex cycle, and the vibrating head 7
As shown by arrow P3 in Figure A, a zigzag-like descending motion is performed, and the coil spring 2 presses the furnace cloth hanging rod 3 that comes into contact with it during the descent.
Then, as shown by the arrow P3' in FIG. As a result, the furnace scum adhering to the furnace cloth 4 is effectively brushed off. In addition, also in the case of the rising process of the vibrating head 7,
Similarly, the vibrating head 7 follows a zigzag-like stroke, causing the furnace cloth 4 to flutter and oscillate, thereby performing the furnace cloth 4. In this embodiment, air cylinders 8 and 9 are used to drive the head mounting base 6 forward and backward and the vibrating head 7 is moved up and down, but hydraulic cylinders may also be used instead. .

According to the oven cloth vibrating device of the present invention, the head mounting base 6 is provided on the movable base 5 and is movable in the opening direction of the oven plate.
A vibrating head 7 is provided on the head mount 6 and is reciprocally driven by a first fluid pressure cylinder (first air cylinder 8) provided on the movable base 5, and is also provided on the head mount 6 and is movable up and down. Second fluid pressure cylinder (second air cylinder 9
), the vibrating head 7 moves up and down in a zigzag pattern due to the cooperative action of the first and second fluid pressure cylinders, and the vibrating head 7 moves up and down with respect to the furnace cloth 4 and in the front and rear directions. This allows the furnace cloth 4 to be swayed at the same time, and the furnace cloth 4 can be sufficiently removed from the furnace hair.

Furthermore, there is almost no sliding action of the vibrating head 7 on the furnace cloth hanging ridge 3, and the inconvenience that the furnace cloth 4 suspended from the furnace cloth hanging ridge 3 is damaged by the reciprocating movement of the vibrating head 7 can be avoided.

Moreover, in order to impart zigzag motion to the vibrating head 7,
Since the separate first and second fluid pressure cylinders combine driving from two directions, the stroke and operation cycle of each drive can be adjusted freely.
It also has the effect of being able to easily set a desired operating state and being highly versatile.
