Description

[Detailed Description of the Invention] This invention applies vibration to a cloth hanging rod installed horizontally in a direction perpendicular to the opening direction of a hanging plate to swing the cloth suspended from the cloth hanging rod. This invention relates to a cloth vibrating device for a filter press that shakes off slag adhering to the cloth.

As a conventional example of this kind of cloth vibrating device for a filter press, after the vibrating head is lowered to a height where it comes into pressure contact with the cloth hanging rod, the rotational motion of the crank is transmitted to the vibrating head, and the vibration that presses against the cloth hanging rod is transmitted. There is a known device (Japanese Patent Publication No. 54-24747) that gives a circular motion to the head and swings the cloth thereby.

However, in the conventional example, a pair of cranks formed by protruding crank pins at positions eccentric from the center of rotation of the rotating disk are separately installed on the left and right sides of the head mounting base on which the vibrating head is supported. A pair of cranks and a head mounting base constitute a parallel crank mechanism, and a belt connects the rotating discs forming each crank.
In synchronization with the rotational drive of one crank, the other crank is rotated, thereby ensuring stable circular motion of the vibrating head.In addition to installing the cranks in parallel, it is also possible to Not only is the structure complicated, as belts are connected and rotated synchronously, but if you want to change the vibration stroke of the vibrating head, you are forced to change the design of multiple parts, making it difficult to respond easily and lacking in versatility. has.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cloth vibrating device for a filter press that eliminates the above-mentioned drawbacks of the conventional example, has a simple structure, provides stable operation of the vibrating head, and can easily change the vibrating stroke. It is something.

Hereinafter, one embodiment of the cloth vibrating device for a filter press of the present invention will be described based on the drawings. As shown, a cloth hanging rod 3 is suspended between arms 1, 1 protruding from both ends of the upper part of each plate via coil springs 2, 2, and a cloth 4 suspended from this cloth hanging rod 3 is suspended between each plate. In a filter press designed to be clamped, the cloth vibrating device applies vibration to the cloth hanging rod 3 to swing the cloth 4, and includes a movable base 5 that can move forward and backward in the direction in which the plate is opened, and a first The vertical vertical axis (hereinafter referred to as the vertical guide axis) 6, which is the axis of the set of
6. It is supported by the movable base 5 via the second set of axes, ie, the forward and backward horizontal axes (hereinafter referred to as forward and backward guide axes) 7, and is movable within a predetermined vertical plane parallel to the opening direction of the plate. a head mounting base (head operating means) 8;
A crank drive means 9 provided on the movable base 5, a crank 11 that links the crank axle 10 of the crank drive means 9 to the head mount 8 and rotates the head mount 8 in response to the rotation of the crank axle 10, and the head. a vibrating head 12 that is supported by a mounting base 8 so as to be able to rise and fall and is pressed against the cloth hanging rod 3 at a predetermined lowered position;
The head lifting means 13 is provided on the head mounting base 8 and drives the vibrating head 12 up and down.

The movable base 5 has a rectangular parallelepiped frame shape, and the movable base 5
Guide rollers 14 pivotally mounted on both front and rear sides of the
A pair of left and right base guide rails 15, 15 arranged above the cloth hanging rod 3 in parallel with the plate guide rail.
The movable base 5 is moved forward and backward in the direction in which the plate is opened by being pulled by a known chain conveyor (not shown).

The elevating guide shafts 6, 6 are vertically arranged as a pair between the upper frame 5a and the lower frame 5b on one side of the movable base 5, while the advancing/retracting guide shafts 7, 7 are formed by guide sleeves formed at both ends thereof. 7a, 7a are fitted onto the respective lifting guide shafts 6, 6, and the lifting guide shafts 6,
They are horizontally suspended between 6 spaces, and are arranged vertically in pairs so that they can slide freely in the vertical direction.

The head mounting base 8 has an I-shape in which a pair of upper and lower horizontal guide sleeves 16, 16' are connected and integrated by a vertical plate member 17. . 7, it can also be freely moved in the vertical direction.

The crank drive means 9 is operated by a motor 18 installed on the movable base 5, and the axis of which is aligned perpendicular to the moving vertical plane of the head mount 8, that is, parallel to the cloth hanging rod 3, at the bottom of the movable base 5. Motor 1 is pivoted on
8 as a drive source and a crank axle 10 that rotates, while the crank 11 is connected to a head mounting base 8.
a crank pin 19 protruding from the back surface of the lower horizontal guide sleeve 16', and a crank arm whose base end is pivotally attached to the crank axle 10 and the crank pin 19 is rotatably fitted into the pin insertion hole 20a at the tip. It consists of 20.

The head elevating means 13 consists of an air cylinder,
The piston rod 13a is placed vertically on the front surface of the vertical plate member 17 of the head mounting base 8 with the piston rod 13a facing downward, and the vibrating head 12 connected to the lower end of the piston rod 13a is driven up and down toward the cloth hanging rod 3 arranged below. That's what I do. A pair of guide shafts 21, 21 are further provided vertically on the upper end surface of the vibrating head 12, and these guide shafts 21, 21 are formed on both ends of the surface of the lower horizontal guide sleeve 16' of the head mounting base 8, forming a vertical guide sleeve. 22, 22, so that the vibrating head 12 can be smoothly raised and lowered relative to the head mounting base 8. The lower end surface of the vibrating head 12 that contacts 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 cloth hanging rod 3.

The pressurized air supply pipe connected to the cylinder part of the head elevating means 13 is provided with sufficient slack to allow movement of the movable base 5, and the base guide rail 1
It is arranged above 5 and 15.

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

When the compression process of the filter press is completed and the plate is in an open state, the movable base 5 is pulled by the chain conveyor and moves onto the cloth 4. Then, the pressurized air supply control means (not shown) starts driving, and the head lifting means 13 lowers the vibrating head 12 to a position where it can act on the cloth hanging rod 3 as shown by the imaginary line in FIG.

When the motor 18 is driven in the lowered state in which the vibrating head 12 can act on the cloth hanging rod 3, the sprocket 23, chain 24, and sprocket 2
A crank axle 10 is rotationally driven through the crankshaft 5, and the rotation of the crank axle 10 is transmitted to the head mount 8 through the crank 11, and the head mount 8 is moved freely in the forward and backward direction by being guided by the forward and backward guide shafts 7, 7. The head mounting base 8 is attached to the crank axle 10 and the crank pin 19 due to the degree of freedom in the vertical direction of the advance/retreat guide shafts 7, 7 guided by the elevation guide shafts 6, 6.
The vibrating head 12, which is integrated with the head mount 8, similarly moves in a circular motion. Along with this movement, the cloth hanging rod 3, which is pressed against the vibrating head 12, makes a circular motion as shown by the imaginary line in FIG. In addition, the cloth hanging rod 3 slides in the opposite direction due to the restoring action of the coil spring 2 in response to the back and forth pressing motion of the vibrating head 12, causing the cloth to adhere to the cloth 4. The slag is effectively brushed off.

In this embodiment, the head mounting base 8 is directly guided in the forward and backward directions by the forward and backward guide shafts 7, 7, while the forward and backward guide shafts 7, 7 are guided in the vertical direction by the vertical guide shafts 6, 6 fixed to the movable base 5. By doing so, the head mount 8 is given a degree of freedom in the forward and backward directions and in the vertical direction. However, it goes without saying that the elevation guide shaft may be configured to be guided in the forward and backward directions by a forward and backward guide shaft fixed to the movable base.

The filter cloth vibrating device of the present invention applies vibration to a filter cloth hanging rod that is suspended via a spring and installed horizontally in a direction perpendicular to the direction in which the filter plate is compressed and pulled back. In a filter press configured to swing the filter cloth, a movable base that can be moved horizontally in the direction of compressing and pulling back the filter plate is provided, and a movable base that can be moved horizontally in the direction of compressing and pulling back the filter plate is provided. a first set of axes located in a vertical plane and parallel to each other;
A second shaft is provided that spans the first set of shafts, is slidable in the axial direction of the first set of shafts, and is parallel to each other; A head mount is provided which is slidable in the axial direction of the shaft, and a vibrating head is installed on the head mount via head elevating means such as an air cylinder. A crank pin is provided protruding in a horizontal direction perpendicular to the pull-back direction, a crank axle is provided on the movable base in a horizontal direction perpendicular to the filter plate compression/pull-back direction, and the crank axle and the crank pin are connected to a crank arm. Since the rotary drive means is provided on the crank axle, the structure is simple and the vibration stroke of the vibration head can be easily changed, making it suitable for versatility.

That is, in the filter cloth vibrating device of the present invention, the head mounting base is slidably provided on the second set of shafts, and the second set of shafts is mounted on the first set of shafts provided on the movable base. The first set of shafts is a set of mutually parallel shafts located in a vertical plane parallel to the direction of squeezing and pulling back the filter plate, and the second set of shafts Since the axes are a set of mutually parallel axes spanned by the first set of axes, the head mount moves while maintaining the same posture in a vertical plane parallel to the direction of squeezing and pulling back the filter plate. It is possible and
Moreover, a crank pin is protruded from the head mounting base,
This crank pin is connected to the crank axle by a crank alarm, and by rotating the crank axle, the crank pin is rotated around the crank axle, so the rotational force of the crank axle is directly transmitted to the head mounting base. Furthermore, since the power is transmitted to a single crank pin protruding from the head mount, the bending moment between the head mount and other members is small, and the sliding parts are smooth.

Further, a crank pin is protruded from the head mount, and the crank pin is rotated by a crank alarm, and the head mount is connected to the filter plate by the first set of shafts and the second set of shafts. Since it is configured to be movable in a vertical plane parallel to the direction of squeezing and pulling back, there is no need to provide two rotating disks as was required in the conventional technique of Japanese Patent Publication No. 54-24747. This has the effect of making the device smaller and more versatile.
