Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cloth suspension device for a filter press.

As a device for suspending the cloth stretched on the surface of each plate of the filter press, support arms are pivotally attached to the left and right sides of the plate, and a cloth hanging rod is elastically hung horizontally between the left and right support arms. A device in which a cloth is suspended from a hanging rod is known. Conventional examples thereof are shown in FIGS. 1 to 3.

The cloth hanging device shown in FIGS. 1 and 2 is
A pair of support arms 2, 2 are pivotally attached to both sides of the plate 1, and a cloth is inserted between one support arm 2 on one side of the plate 1 and one support arm 2 on the other side via a spring 3. A hanging horizontal bar 4 is suspended, and the upper end of a cloth 5 stretched on the surface of each plate 1 is fixed to the corresponding cloth hanging horizontal bar 4.

However, in this device, after the compression process of the filter press is completed, the plates 1 and 1 are opened, and
In order to remove the slag adhering to the cloth 5, one support arm 2 of each board 1 is tied between adjacent boards 1, 1 with a string 6, and the support arms of each other are connected through this string 6. While tilting the support arm 2 so that the plates 2 and 2 attract each other as the plate opens, the plate 1
and each support arm 2 are tied with another string 7 to restrict the support arm 2 to a predetermined inclined posture, thereby separating the cloth 5 from the plate surface, so that the cloth 5 can be supported in the closed state. In order to keep the arm 2 in a vertical position, it is necessary to provide a stopper on the side of the plate and the support arm 2, and also to provide strings 6, 7, etc. to tie between the plate 1 and the support arm 2 and between the support arms 2, 2. However, the overall structure is complicated, and the slack in the strings 6 and 7 hinders the opening and closing operations.

Moreover, when the fabric vibrating device applies vibration to the fabric 5 via the fabric hanging horizontal bar 4, the impact is applied to the string 7, so the string 7 must be made of wire rope, chain, or other material having sufficient strength. The presence of the string 7 further impedes smooth opening and closing operations.

Further, in the above-mentioned device, both ends of the cloth hanging horizontal bar 4 are inserted into the long holes 2a formed in the support arm 2, and the vertical displacement thereof is regulated along the longitudinal direction of the support arm 2. Since the vibration direction of the cloth hanging horizontal bar 4 is not disturbed, most of the force applied to the cloth hanging horizontal bar 4 by the head of the cloth vibrating device is absorbed by the support arm 2, and sufficient cloth vibration is achieved. It has the disadvantage of not being effective.

On the other hand, in the cloth hanging device shown in FIG. 3, between adjacent plates 1', 1', one support arm 2', 2' of each plate 1' is pivotally connected at its tip. 8 and a pivoting portion 9 at the tip of the support arm.
A cloth hanging horizontal bar 4' is suspended between both sides of the plate 1' via a spring 10 connected to the support arm 2', and another auxiliary horizontal bar 11 is suspended horizontally at the intermediate part of each support arm 2'. The middle part of the cloth 5' hung on the surface of the plate 1' is hung on the auxiliary horizontal bar 11, and its upper end is suspended on the cloth hanging horizontal bar 4'.

In the case of this device, the cloths 5' and 5' stretched on the opposing plate surfaces are suspended by sharing one cloth hanging horizontal bar 4', so the cloth It is effective in that the two cloths 5', 5' can be frayed at the same time just by acting on the vibrating device, but each cloth 5', 5' is in a state where the middle part is hung on the auxiliary horizontal bar 11. Since the vibration applied to the cloth hanging horizontal bar 4' is not directly transmitted to the cloth 5', it is partially absorbed by the auxiliary horizontal bar 11. It has the disadvantage that the cloth vibration effect cannot be obtained. In addition, in the open state, the cloths 5', 5' are stretched above the cloth hanging horizontal bars 4' and the auxiliary horizontal bars 11, 11 between the plates 1', 1'. The cleaning nozzle cannot be introduced from above,
There are disadvantages in that the cleaning device can only be installed below or to the side of the plate 1', and the entire filter press cannot be constructed compactly.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cloth suspension device for a filter press which eliminates the above-mentioned drawbacks of the conventional example, has a simple structure, and is capable of sufficiently increasing the vibration effect on the cloth.

An embodiment of the present invention will be described below with reference to FIGS. 4 and 5.

The cloth hanging device of this embodiment consists of a pair of side bars 12, 12 which are arranged in parallel between the front and rear machine frames (not shown).
A plurality of plates 13... are slidably suspended between them, and a pair of support arms 14, 14 are pivotally attached to the handles 13a on both sides of these plates 13, and the tips of each support arm 14, 14 are This is a single type filter press in which the plates 13, 13 are connected by a link mechanism constituted by the support arms 14, which are pivotally connected to the tip of one of the support arms 14 of the front and rear adjacent plates 13, 13. It was applied. 15 is a support arm 1 for the front and rear plates 13, 13;
A pair of hooks 17, 17 are suspended from this pivot pin 15 via coil springs 16, 16. Reference numeral 18 denotes a connecting fitting that connects the coil spring 16 and the pivot pin 15. 19, 19 is the hook 17, 17 on the right side
and one of the hooks 17, 17 on the left side, and are suspended separately, and include a mounting rod portion 19a that is immediately latched to the hook 17, and a cloth hanging rod portion. It has a two-stage structure with 19b. Reference numeral 20 denotes a cloth stretched over the front and rear surfaces of the plate 13, a part of which is hung on the inner edge of the stock solution hole 21 in the center of the plate, while the upper side of the cloth 20 is attached to the cloth hanging rod of the cloth hanging horizontal rod 19. A mounting rod 2 is hung on the portion 19b, and its upper end is horizontally installed at the upper end of the plate.
It is attached to 2. The mounting rod 22 is attached to each plate 13.
A pair of cloths 20, 20 are provided for each panel, and each of the cloths 20, 20 stretched on the front and rear surfaces of the plate 13 is fixed separately.

Connecting fittings 18, 18 connected to the pivot pin 15
One of the two is attached to the outside of the support arm pivot, and the other is attached to the inside of the support arm pivot. As a result, the two hooks 17, 17 are divided into the outer side and the inner side on the side of the plate 13, so that when the support arms 14... are in a vertical position when the plate is closed, the two sets of coil springs 16, 16 and the hooks 17, 17 are separated. fits neatly without interference.

Since there is a limit to the thickness of the plate 13, a pair of support arms 14 are attached coaxially to one pivot shaft 23 provided on the plate handle 13a, overlapping each other. And the adjacent board 13,1
two support arms 14, 1 pivotally connected to each other between 3;
4 is set so that there is a slight gap when the plate is closed, and this gap allows the mounting rod part 19a of one of the cloth hanging horizontal rods 19 to be latched to the outer hook 17.
is arranged so that it faces outward.

In this cloth hanging device, the support arms 14, 14 of the adjacent plates 13, 13 are tilted as shown in FIG. cloth stretched on 2
0 and 20 are pulled by hooks 17 and 17, respectively, and are separated from the plate surface. Moreover, hook 17,
Since 17 is connected to the coil springs 16, 16, the cloths 20, 20 are kept in a stretched state without slack.

Under the above-mentioned open state, the head portion 24 of the cloth vibrating device is applied to the mounting rod portion 19a of the cloth hanging horizontal bar 19 as shown by the imaginary line in FIG. 5, and the cloth vibrating device is driven to By swinging the rod 19 up and down or back and forth, the cloth 20 receives the vibration.
20 repeats relaxation and expansion, and the slag is brushed off by the dusting action at this time.

Moreover, since the two opposing cloths 20, 20 are suspended by separate cloth hanging horizontal bars 19, 19,
In the open state, the upper part between the adjacent plates 13, 13 is not completely covered with the cloth 20, and even when a cleaning device is placed above the plate 13, the nozzle is inserted from above with the two cloths 20, 20. It can be introduced in between.

The upper end of the cloth 20 is not directly fixed to the cloth hanging horizontal bar 19, but the upper end of the cloth 20 is attached to the cloth hanging horizontal rod 19.
The cloth 20 is hung on the cloth hanging rod 19b and its upper end is fixed to the mounting rod 22 at the upper end of the plate.
The upper side of the nozzle is drawn toward the plate surface side to some extent, and the open space above the plate is further expanded, making it easier to introduce the nozzle from above. In particular, in the case of a filter press in which the stock solution hole 21' is biased toward the lower side of the plate 13', as in the embodiment shown in FIGS. 6 and 7, the pivot of the support arm 14 and the plate 13' Since the line segment connecting the stock solution holes 21' (indicated by imaginary lines in FIG. 6) is biased toward the center of the plate surface, by using this cloth hanging device in such a filter press, the cloth 2 can be
The upper end of the plate 13' is drawn toward the upper end of the plate 13', thereby further increasing the effect of expanding the upper space.

Further, since the cloth suspension horizontal bar 19 has a two-stage structure consisting of the mounting rod portion 19a and the cloth suspension rod portion 19b, the head portion 24 of the cloth vibrating device can directly touch the cloth 2.
It does not come into sliding contact with the cloth 20 and does not damage the cloth 20.

According to the cloth hanging device of the present invention, a pair of support arms are pivotally attached to the left and right sides of the plate, and
Between adjacent plates, one support arm of each plate is pivotally connected at its tip to form a link, and a pair of links are connected between both sides of the plates via a spring connected to the pivot at the tip of the support arm. Each cloth hanging horizontal bar was suspended separately, and the cloth hung on the surface of the board was hung on one of the corresponding cloth hanging horizontal bars and its upper end was fixed to the upper end of the board. The vibration applied directly to the cloth increases the effectiveness of sludge removal, and the structure is simple, with sufficient open space above between the plates when the plates are opened, making it possible to introduce a cleaning nozzle from above. This allows the cleaning device to be placed above the filter press, which has the effect of making the entire filter press more compact.
