Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a moving device for slag removal equipment in a filter press.

Generally, a filter press is equipped with equipment such as a vibrator and a washer to remove slag when opening a large number of plates. In conventional filter presses, rails for moving the slag removal equipment are placed above many plates over almost the entire length of the filter press. This had the disadvantage that the rails became stiff during work such as replacing plates or boards, resulting in very poor workability. In order to eliminate these drawbacks, we have proposed a device in which the conventional rail installation is abolished and a portal-shaped moving frame is placed so as to straddle the board when viewed from the front, and a slag removal device is attached to this moving frame. It was done. However, this conventional device has a problem in that the mechanism for moving the gate-shaped frame equipped with the slag removal equipment is complicated and the equipment cost is extremely high.

This invention was made to solve the above problem, and utilizes a board pull-back mechanism to open a large number of boards, and moves a portal-shaped moving frame equipped with a slag removal device to a predetermined length at a time. It is movable, allows for smooth removal of slag during opening, has a very simple structure, reduces equipment costs, and eliminates slag during cloth replacement. It is possible to open only the board without moving the removal equipment, which is very efficient, and it is also an emergency method that can correct the deviation of the stopping position of the slag removal equipment during the opening operation of multiple boards. The purpose of the present invention is to provide a device for moving sludge removing equipment in a filter press that is convenient for use.

Reference numeral 5 denotes cloth hanging rods attached to both ends of the cloth 20, and both ends of the rods are suspended from an arm 34 via a pair of springs 36 so as to be vertically movable.

Next, the operation of the filter press will be explained.

Immediately after the overwork is finished, all the plates 5 are moved to the receiving plate 3 by the push plate 4, as shown in
A portal-shaped moving frame 14, pushed to the side and equipped with a vibrator 17, is located near the rear end of the filter press. First, the push plate 4 is moved backward, the chain 7 is rotated clockwise in the figure, and the towed body 10, which includes the plate pull-back pawl 22 and the stop pawl 13, moves forward. At this time, as shown in FIG. 6, the engagement pins 22 on the front sides of the movable bodies 15 on both sides of the moving frame 14 are made to protrude, and the towed body 1
0 moves forward, the feed pawl 11 attached to its rear end engages with this engagement pin 22, whereby the movable body 15 and the vibrator 17 provided on the movable frame 14 are moved together. is forced to move forward. And the pull-back claw 1 of the towed object 10
2 hits the hanger 6 of the first plate 5 and passes under the hanger 6 against the spring force, and after this pull-back claw 12 passes forward over the hanger 6, the stop claw 1
3 hits the hanger 6 and the towed body 10 stops, thereby stopping the movable body 15 and the vibrator 17 integrated therewith. At this time, the movable body 15 tends to move forward a little due to inertia, but is immediately stopped on the spot by the action of a brake 29 provided at its rear end. When the towed body 10 stops, the chain 7 is immediately rotated in the opposite direction. Due to the reverse rotation of the chain 7, the towed object 10 is pulled back by its retraction claw 1.
2, the board 5 is moved backward while being hooked on the hanging hand 6, and stopped when the board 5 reaches the front surface of the push board 4. Note that the mechanism for pulling back the plate 5 by the towed body 10, which is provided with the plate pull-back pawl 12 and the stop pawl 13, is already well known, and is described in detail in, for example, Japanese Patent Publication No. 52-36632 proposed by the present applicant. It has been stated.

While the plate 5 is being pulled back, the vibrator 17 is stopped, and when the plate 5 stops, the vibrator 17 is positioned exactly at the center of the gap between the plates. Then, by the operation of the vibrator 17, the slag adhering to the cloth 20 of the plate 5 in the open state falls and is removed. Next, the towed body 10 moves forward as the chain 7 rotates clockwise again, and moves toward the second plate 5.
When approaching this plate 5, the towed object 10
The feed pawl 21 of the movable body 15 engages with the engagement pin 22 of the movable body 15, and the towed body 10 moves the movable body 15 and the vibrator 17 integrated therewith by a predetermined length, and then moves to the second position.
When the stop claw 13 hits the hanger 6 of the second plate 5, it stops. Here, the vibrator 17 moves forward by a length corresponding to the missing first plate 5, that is, by a length corresponding to the thickness of the plate 5, and then stops. Then, when the second plate 5 is pulled back and stopped in the same way as the first plate 5, the vibrator 17 is positioned approximately at the center of the gap between the open plates; The slag is removed by the action of Similarly, board 5
are sequentially opened, and each time the vibrator 17 is advanced by the thickness of the plate 5, the slag removal action is repeated.

By the way, when a large number of plates 5 are opened, the gap between the plates gradually narrows, and the vibrator 17 moves forward by a constant length corresponding to the thickness of the plate 5, so that the stopping position of the vibrator 17 is at the center of the gap between the plates. As a result, the slag will gradually shift toward the rear, which will hinder the slag removal work.

That is, when all the plates 5 are pressed under high pressure by the pressing plate 4, there is no gap between the adjacent plates 5, and there is no gap between the plates 5, as shown in FIG. 1, for example. The cloth 6 is also compressed by high pressure and has a minimum thickness. On the other hand, no pressing force is applied to the plate 5, which has been successively pulled back by the plate opening operation as described above and is waiting at the rear of the filter press, so that, for example, as shown in FIGS. 2 and 6, ,
A gap 37 is inevitably formed between adjacent plates 5. Since this gap 37 accumulates each time the plate 5 is opened, the gap between the plates becomes narrower as the plate 5 is opened. In contrast,
Since the vibrator 17 is accurately moved by a length corresponding to the thickness of the plate 5 each time the plate 5 is opened, the position of the vibrator 17 gradually shifts backward from the center of the gap between the plates, and the vibrator 17 This will impede the sludge removal effect.

Therefore, when, for example, half of all the plates 5 are opened, the engagement pins 22 of the movable body 15 are retracted, and the position adjustment engagement pins 22 arranged a predetermined length behind the movable body 15 are retracted. The pin 24 is made to protrude. As a result, the feed pawl 21 of the towed object 10 now engages with this engagement pin 24, and therefore the stopping position of the movable body 15 and the vibrator 17 is between this engagement pin 24 and the previous engagement pin 22. As a result, the vibrator 17 is corrected to be located approximately at the center of the gap between the open plates.

After all the plates 5 have been opened, the return pawl 30 attached to a predetermined location of the chain 7 hooks the engagement pin 22 or 24 of the movable body 15 and retreats, so that the vibrator 17 is is returned to the standby position.

Note that, for example, when replacing the cloth 20,
When only the plate 5 is moved and the vibrator 17 is not moved, by retracting both the engagement pins 22 and 24, only the towed body 10 is reciprocated to perform the plate opening operation. can be done.

In the above embodiment, in order to correct the deviation of the stop position of the vibrator 17, the engaging pins 22, 2
Although two engaging pins 4 are provided, three or more engaging pins 2 may be provided depending on the number of plates 5 of the filter press.
2 and 24 may be arranged at a predetermined distance from each other. Further, in the embodiment, the feed claw 21 is attached to the towed object 10.
The engaging pins 22 and 24 are attached to the movable body 15 side, but since these positions are relative, the feed pawl 21 is fixed to the movable body 15 side.
5 side, and the engagement pins 22 and 24 of the plurality of cylinders 23 and 25 may be attached to the towed body 10. Note that the engaging pins 22 and 24 may be moved in and out by an electromagnetic mechanism or the like.

Further, in the above embodiment, the portal-shaped movable frame 14 is equipped with only the vibrator 17 as a device for removing slag; In some cases, a machine is provided separately.

According to the first aspect of the present invention, a reciprocating pulling member 7 is disposed below a large number of plate hangers 6, and the pulling member 7 is urged by a push-up spring. A towed body 10 equipped with a pullback claw 12 and a stop claw 13 that can move vertically is attached, and a movable body 15 that supports a moving frame 14 equipped with a slag removal device 17 is movable back and forth on the outside of the traction member 7. A feed pawl 21 is attached to one of the towed body 10 and the movable body 15, and an engagement pin 22 that engages with the feed pawl 21 and can be taken in and out is attached to the other. With the attached device, the sludge removal device 17 can be moved by a predetermined length as the board 5 is opened, and the sludge removal work can be carried out smoothly during the opening of the board. Since the slag removing device 17 is moved by a predetermined length by using a plate pull-back mechanism for opening a large number of plates 5, the structure is very simple and the equipment cost is low. Also, when replacing the cloth 20, by retracting the engagement pin 22,
Only the plate 5 can be opened without moving the slag removing device 17, resulting in very good workability.

According to the second aspect of the present invention, at least one position-adjusting engagement pin 24 that can be taken in and out is arranged at a predetermined distance from the engagement pin 22 in the first aspect, When the required number of plates 5 are opened, the position adjustment engagement pin 24 protrudes in place of the engagement pin 22 and the feed claw 21
Since it is designed to interact with the cloth 20 of all the plates 5, it is possible to correct the deviation of the stopping position of the slag removing device 17 during the opening operation of the plate 5, and therefore, the slag can be removed from the cloth 20 of all the plates 5. This has the effect that it can be carried out reliably.
