Abstract

PURPOSE:To shake off a filter cake adhered to filter cloth, by applying vibration to a filter cloth suspending rod traversely provided in a direction at right angles respect to the open direction of filter plates suspended through a spring to shake the filter cloth suspended from the filter cloth suspending rod. CONSTITUTION:One end part of a head attaching base 11 is engaged with the linearly advancing guide rail 6 of a moving base 5 through a slider 9 in a freely slidable manner and the other end part of the attaching base 11 is engaged with the crank open direction of filter plates. Because a filter cloth suspending rod 3 is pressed by a vibration head 12 supported by the attaching base 11 to shake the filter cloth 4, the pressing direction with respect to the cloth suspending rod 3 is successively changed in addition to the displacement in an up-and- down direction while strong strinking operation is applied to the filter cloth 4 and a filter cake adhered to the filter cloth 4 can be effectively shaken off.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention applies vibration to a furnace cloth suspension rod installed horizontally in a direction perpendicular to the opening direction of a suspended furnace plate, and a furnace cloth suspended from a hanging furnace plate υ rod. This invention relates to a furnace cloth vibration device for a filter press that shakes off Kunohe slag adhering to the furnace cloth by shaking the furnace cloth.

As a conventional example of a furnace cloth vibrating device for this type of filter press, the vibration is lowered by 1 rad to the position where it comes into pressure contact with the furnace cloth hanging rod, and then the vibrating cloth is driven forward and backward to move the furnace cloth by the action of the corrugated part at the lower end of the vibrating head. A device that vibrates the cloth (Special Publication No. 19622/1983) transmits the rotational motion of a crank to the vibrating head, which gives a circular motion to the vibrating head that is connected to the furnace cloth hanging rod, thereby shaking the furnace cloth. Things that move (Special Publication No. 54-24747
No.) etc. are known.

However, the configuration in which the oven cloth suspension rod is oscillated by the corrugated portion at the lower end of the vibrating head has a problem in that the oven cloth is easily damaged because the oven cloth is rubbed by the sliding action of the vibrating head.

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 splints. This is the purpose.

Hereinafter, one embodiment of the filter press oven cloth vibrating device of the present invention will be described based on the drawings. 7) While supporting the door plate so that it can freely slide, a furnace cloth hanging rod 3 is suspended between arms 1 and 1 protruding from both ends of the upper part of each door plate via coil springs 2 and 2, as shown in Fig. 1. Then, hang fcP from this furnace cloth hanging rod 3.
In a filter press in which a cloth 4 is sandwiched between each furnace plate, a furnace cloth vibrating device applies vibration to the cloth metering rod 3 to swing the furnace cloth 4, and the furnace cloth vibration device is configured to vibrate the cloth 4 in the opening direction of the door plate. A movable base 5 that can move forward and backward, a linear guide rail 6 provided on one side of the movable base 5 in the direction of opening the oven plate as shown in FIGS. 3 and 4, and a crank axle 7. A crank drive means 8 is provided on the movable base 5 so as to be parallel to the furnace cloth hanging rod 3, and one end is slidably engaged with the linear guide rail 6 via a roll slider 9, while the other end is A head mount 11 is linked to the crank axle 7 of the crank drive means 8 via the crank 10, and is capable of swinging within a predetermined vertical plane parallel to the opening direction of the furnace plate using the roll slider 9 as a fulcrum. , a vibrating head 12 that is supported on the head mount 11 so as to be movable up and down and can be lowered at a position that can act on the furnace cloth hanger n3, and a head lifting means provided on the head mount 11 for driving the vibrating head 12 up and down. It is composed of 13.

The movable base 5 has the shape of a rectangular parallelepiped frame, and guide rollers 14 pivoted on both front and rear sides of the movable base 5 are arranged above the furnace cloth hanging rod 3 in parallel with the R-plate guide rails. The movable base 5 is moved forward and backward in the door opening direction by being suspended from a pair of left and right base guide rails 15 and pulled by a chain conveyor (not shown).

The straight guide rail 6 is a lower frame 5a of one side of the movable base 5.
It consists of lip channel steel installed horizontally with the opening facing outward.

The crank drive means 8 is rotatably supported by a motor 16 installed on the movable base 5 and a lower part of the movable base 5 with its axis aligned parallel to the furnace cloth hanging rod 3, and uses the motor 16 as a drive source. It consists of a rotating crank axle 7.

The head mounting base 11 has a horizontal seat plate part 11a and a vertical back plate part 1.
1b, and has a vertical back plate portion 11b.
The roll slider 9, which is pivoted at one end and protrudes from the rear side, is fitted into the straight guide rail 6, and the inward 7 flange of the straight guide rail 6 prevents the roll slider 9 from coming out. The crank pin 18 of the crank lO, which is composed of a crank arm 17 having a central portion pivoted thereon, and a crank pin 18 protruding from the tip of the crank arm 17, is pivoted to the other end of the vertical back plate portion 11b. The rotation of the axle 7 is transmitted to the head mounting base 1 via the crank 10.
I am trying to communicate this to 1.

The head elevating means 13 consists of an air cylinder, and is vertically disposed on the horizontal seat plate 11a of the head mount 11 with its piston rod 13a facing downward, and the vibrating head 12 connected to the lower end of the piston rod 13a is arranged below. ν cloth amount υ

12a + 12a are installed vertically, and this guide shaft 12a
, 12a are inserted into vertical guide sleeves IIQ, 110 formed at both ends of the horizontal seat plate portion 11a of the head mount 11, so that the vibrating head 12 can be smoothly moved up and down with respect to the head mount 11. The lower end surface of the vibrating head 12 that corresponds to the cloth hanging rod 3 is covered with a rubber sheet or cloth to prevent the vibrating head 12 from slipping with respect to the furnace cloth hanging rod 3.

The pressurized air supply pipe connected to the cylinder portion of the head elevating means 13 is provided above the base guide rail 15° 15 with sufficient slack to allow movement of the movable base 5. .

Next, the operation of the oven cloth vibrating device will be explained.

When the filter press finishes the squeezing process and the furnace plate is in an open state, the movable base 5 is pulled by the chain conveyor and moves onto the furnace cloth 4. Then, the pressurized air supply control means (not shown) starts driving, and the head raising/lowering means 13 lowers the vibrating head 12 to a point t at which it can act on the offloading rod 3 as shown by the imaginary line in FIG.

When the motor 16 is driven in the lowered state in which the vibrating head 12 can act on the furnace cloth hanging rod 3, the sprocket 19

It corresponds to l.

In the oscillating operation of the vibrating head 12, the vibrating head 1
2 not only displaces in the vertical direction, but also sequentially changes the direction in which it is pressed against the furnace cloth rod 3, so that a large dusting action is applied to the furnace cloth 4, and the furnace slag adhering to the furnace cloth 4 is effectively brushed off. Ru. Moreover, when the vibrating head 12 is displaced back and forth and the strong restoring force of the coil spring 2 acts on the furnace cloth hanging rod 3, the posture of the vibrating head 12 shifts to an inclined state! 7 Since the restoring operation of the furnace cloth hanging rod 3 is regulated, there is almost no sliding movement on the furnace cloth hanging rod 3 due to the swinging movement of the vibrating head 12, and the furnace cloth 4 is not rubbed by the vibrating head 12. Inconveniences such as damage are avoided.

According to the oven cloth vibration device of the present invention, one end of the head mounting base 11 is slidably suspended on the linear guide rail 6 of the movable base 5 via the slider 9, and the head mounting base 11 is attached via the crank lO. The other end of the stand 11 is linked to the crank axle 7 of the crank drive means 8 on the movable base 5 side, and the head mount 11 is mounted with the slider 9 as a fulcrum within a predetermined vertical plane parallel to the opening direction of the oven plate. The vibrating head 12 supported by the head mount 11 is designed to be able to oscillate, and the furnace plate amount υ is
Since the furnace cloth 4 is configured to swing by pressing the rod 3,
The following effects can be obtained.

(a) The operation of the vibrating head 12 differs from the conventional example in which it moves in a circular motion while maintaining a horizontal position; it oscillates; The pressing direction of the rod 3 is sequentially changed, and a strong dusting action is applied to the furnace cloth 4, so that the furnace slag adhering to the furnace cloth 4 can be effectively brushed off.

(b) With the longitudinal displacement of the vibrating head 12, the vibrating head 1
Since the posture 2 shifts to an inclined state that restricts the restoring operation of the furnace cloth metering rod 3, the vibrating head 12 often slides against the furnace cloth metering rod 3, and the furnace is rubbed by the vibrating head 12. Inconveniences such as damage to the cloth 4 do not occur.

(c) The support structure that movably supports the head mounting base 5 with respect to the movable base 5 has one end suspended by the slider 9 and the linear guide rail 6, and the other end connected to the crank lO by the shift flank axle. 7, the structure is extremely simple compared to the conventional example, sufficient support strength can be ensured, and costs can be significantly reduced.

b) The vibration stroke of the vibration head 12 can be easily adjusted by simply changing the arm length of the crank arm 17 of the crank IO that connects the crank drive means 8 to the head mounting base 11, making the furnace highly versatile. It can be a cloth vibration device.
