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 dregs attached to the cloth.

In a conventional example of this kind of cloth vibrating device for a filter press, the vibrating head is lowered to a position where it comes into pressure contact with the cloth hanging rod, and then the vibrating head is driven forward and backward to vibrate the cloth by the action of the corrugated portion at the lower end of the vibrating head. (Special Publication No. 54-19622), and devices that transmit the rotational movement of a crank to a vibrating head and give a circular motion to the vibrating head that is in pressure contact with a cloth hanging rod, thereby shaking the cloth (Special Publication No. 19622). Publication No. 54-24747) is known.

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

In addition, in a configuration that gives circular motion to the vibrating head,
Since the direction changing operation of the vibrating head is slow during the reciprocating cycle, the shock applied to the cloth hanging rod is weak and the cloth swinging effect is not sufficient.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cloth vibrating device for a filter press that can overcome the above-mentioned drawbacks of the conventional cloth vibrating device for a filter press and can sufficiently vibrate the cloth without damaging the cloth.

Hereinafter, the configuration of the apparatus of the present invention will be explained based on examples.

A crank drive means 7 provided on the base 5 has an upper side surface connected to a crank 6a at one end of a diaphragm drive shaft 6 pivotally supported by the movable support base 5, and a lower side surface allows the crank 6a of the crank drive means 7 to move. A diaphragm 8 held so as to be movable with respect to the movable support base 5 within a range, a diaphragm 9 that is supported by the diaphragm 8 so as to be able to rise and fall and that can be lowered to a position where it can act on the cloth hanging rod 3; The apparatus is characterized in that it comprises a head elevating means 10 for driving the head up and down relative to the diaphragm 8.

The movable support stand 5 has guide rollers 11 and 12 pivotally attached to both side walls below the diaphragm drive shaft 6, and a pair of left and right support stand guide rails 13 disposed above the cloth hanging rod 3 in parallel with the plate guide rails. , 13, and is pulled by a chain conveyor (not shown) to move the movable support base 5 forward and backward in the direction in which the plate is opened.

The crank driving means 7 is connected to a motor 14 installed on the movable support base 5, and is pivotally supported at an intermediate height position of the movable support base 5 so that the shaft center line is parallel to the cloth hanging rod 3. , a chain 16, and a diaphragm drive shaft 6 rotated via a sprocket 17. Reference numeral 18 denotes a weight fixed to one end of the diaphragm drive shaft 6, and the weight 18 maintains the rotation of the diaphragm drive shaft 6 as uniformly as possible, and resists the tension of the spring 2 of the cloth hanging rod 3. 3
It acts to uniformly sway the.

The diaphragm 8 is vertically disposed so as to pass through the lower side of the movable support 5 through an opening 19 formed in the center of the movable support 5 on the diaphragm drive shaft 6 side, and the upper side surface is connected to the diaphragm drive shaft 6 . While being connected to the end face,
A guide pin 20 protruding from the lower side surface toward the diaphragm drive shaft 6 is connected to the diaphragm 8 from the lower end surface of the movable support base 5.
The guide member 21 is inserted into a long hole 22 of a guide member 21 provided parallel to the guide member 21, and is configured such that when the upper end side makes a crank movement, the lower end side can move up and down by the stroke thereof.

The head lifting means 10 consists of an air cylinder,
A vibrating head 9 connected to the downwardly directed lower end of the piston rod 10a is driven up and down toward a cloth hanging rod 3 disposed below. A pair of guide shafts 9a, 9a are further provided vertically on the left and right sides of the upper end surface of the vibrating head 9, and are inserted into vertical guide sleeves 23, 23 provided at both lower ends of the diaphragm 8. This allows the vibration head 9 to move up and down smoothly. The lower end surface of the vibrating head 9 that corresponds to the cloth hanging rod 3 is covered with a rubber sheet or cloth, and the vibrating head 9 that corresponds to the cloth hanging rod 3 is covered with a rubber sheet or cloth.
This is to prevent slippage.

The pressurized air supply pipe connected to the cylinder portion of the head lifting means 10 is provided above the support guide rails 13, 13 with sufficient slack to allow movement of the movable support 5. .

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

When the compression process of the filter press is finished and the plate is in an open state, the movable support table 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 10 lowers the vibrating head 9 to a position where it can act on the cloth hanging rod 3 as shown by the phantom line in FIG.

When the motor 14 is driven in the lowered state in which the vibrating head 9 can act on the cloth hanging rod 3, the sprocket 15, chain 16, and sprocket 17
The diaphragm drive shaft 6 is rotationally driven through the crank 6a, and the rotation of the diaphragm drive shaft 6 is transmitted to the diaphragm 8 through the crank 6a. The diaphragm 8 receiving this transmission slides in the vertical direction along the elongated hole 22 because the lower guide pin 20 is engaged with the elongated hole 22 of the guide member 21 fixed to the movable support base 5. Guide pin 2
It is oscillated around 0.

Therefore, the vibration head 9 integrated with the vibration plate 8 is
As shown by the imaginary line in FIG.
Since the direction of pressure is sequentially changed, a large dusting action is applied to the cloth 4, which is effective not only when the slag attached to the cloth 4 is a large cake piece and is sticky, but also when the cake pieces are small and difficult to remove. It can be brushed off.

Furthermore, since the vertical amplitude of the vibration head 9 can be adjusted by changing the length of the crank 6a of the diaphragm drive shaft 6, this can be adjusted by changing the rotation speed of the diaphragm drive shaft 6. By doing so, the effect of shaking off the dregs attached to the cloth 4 can be changed. Weight 18 attached to the diaphragm drive shaft 6
In order to make the rotation of the diaphragm drive shaft 6 uniform,
Even when the tension of the spring 2 of the cloth hanging rod 3 is relatively strong and uneven, the cloth hanging rod 3 is uniformly swung against the tension of the spring 2 to peel off the dregs.

Although the elongated hole 22 of the guide member 21 is provided in the vertical direction in this embodiment, by changing its direction and shape, the swinging motion of the diaphragm 8 can be further varied.

4 to 6 show other embodiments of the present invention, in which the diaphragm 8, which was slidably held in the elongated hole 22 of the guide member 21 by the guide pin 20 in the previous embodiment, is A case is shown in which the swing arm 25 is rotatably attached to the other end of the swing arm 25 which is pivotally connected to the movable support base 5 on the lower side of the motor 14 by a support shaft 24 and a pin 26 .

When the lower end of the diaphragm 8 is pivoted in this way,
By changing the ratio of the length of the swing arm 25 to the crank 6a, the amount of swing of the lower end of the diaphragm 8 can be adjusted. The effect obtained is the same as described for the previous example.

As explained above, this invention not only provides vertical displacement to the vibrating head via the diaphragm, but also makes it possible to sequentially change the pressing direction without rubbing the cloth against the cloth hanging rod. ,
Various types of slag adhering to the cloth can be effectively brushed off by applying a large dusting motion to the cloth without damaging the cloth.

Moreover, the support structure of the diaphragm for the movable support table is extremely simple compared to the conventional structure and can obtain sufficient support strength, so it can be used even when the tension of the spring of the cloth hanging rod is relatively strong and uneven. , the cloth hanging rod is swung against the tension of the spring,
You can definitely shake off the slag.
