Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a cloth traveling device for a filter press.

The cloth running device of a conventional filter press, which consists of independently running cloth arranged between plates, connects the upper and lower ends of the cloth placed on both the front and back sides of each plate to a string-like power transmission medium through cloth attachment bars. The string-like transmission medium is connected to the upper drive roller and the lower guide roller that are installed on the brackets provided on the left and right sides of the upper and lower sides of each plate, and when the plates are opened, the upper drive roller is connected to the common Since the cloth is driven by a drive device, the structure of the cloth part is delicate and complicated, and the cloth winding roller is installed at the bottom of the plate. , roll up the remaining cake in this part,
The problem was that the cake was transferred to the back side of the cloth, making the liquid cloudy.

The present invention aims to eliminate the above-mentioned drawbacks and provide a fabric traveling device suitable for this type of machine with a large number of plates, which is inexpensive and has a compact structure. Attach the upper end of each cloth to the winding roller, and attach the lower end to the underside of the board. After passing it over the arranged guide rollers, it is attached to the cloth attachment bar, and both left and right ends of each cloth attachment bar are raised and lowered via a common drive device.
It is made to run on cloth.

Hereinafter, the present invention will be described in detail with reference to the drawings showing preferred embodiments.

In the figure, 1 is a fast head, and 2 is a rear head, which are fixed to a frame 5 via leg members 3 and 4, respectively. Reference numeral 6 denotes a side bar, which extends between the fast head 1 and the rear head 2 and is attached to both left and right sides thereof. 7, . . . are plates, and 8 is a loose head, which is supported by the side bar 6 via rollers 9. 10 is a connecting fitting, which connects the fast head 1 and the front end plate;
The plates are connected to each other, and the rear end plate and the loose head 8 are connected to each other. Numeral 11 is a hydraulic cylinder for opening and closing the plate, and is mounted on the rear head 2 so as to slide on the loose head 8. Reference numeral 12 denotes cloth placed on both the front and rear sides of each plate 7. 13 is a pair of upper brackets arranged on the left and right sides of the upper part of each plate 7, 14 is a pair of cloth winding rollers installed on the upper bracket 13;
It is equipped with a winding spring 15 capable of winding up the cloth a little more than the distance required for the cloth to travel. Reference numeral 16 designates a pair of lower brackets disposed on the left and right sides of the lower part of each plate 7, and reference numeral 17 designates a pair of guide rollers installed over the lower brackets 16. Reference numeral 18 denotes a cloth holding roller installed on the lower bracket 16 near the upper side of the guide roller 17, and 19 is a spray pipe installed on the lower bracket 16 near the lower side of the guide roller 17, and is connected to the hose 20. The upper end of each cloth 12 is attached to a winding roller 14, and the lower end thereof is stretched over a guide roller 17 and a presser roller 18, and then attached to a cloth attachment bar 21. Reference numeral 22 is a lifting frame disposed on both the left and right sides of the plate, and supports both the left and right ends of each cloth attachment bar 21 via rollers so as to be slidable in the front and rear directions. 23 is a hydraulic cylinder which is an example of a driving device. FIG. 5 shows another embodiment of the drive device, in which a cloth attachment bar 21 is attached to a drive roller 25 via a string-like transmission medium 24. Drive roller 25
are installed on the upper bracket 13, and are adapted to be interlocked by a common drive shaft 26. 27
is a cake, and 28 is a replaceable spring housing.

In the filter press equipped with the cloth traveling device configured as described above, like in the conventional filter press, after passing and squeezing the stock solution injected between the two cloths interposed between the plates, a hydraulic cylinder 11 to open the gap between the plates 7, .
It is often attached to. Therefore, when a drive device such as the hydraulic cylinder 23 or the drive roller 25 is driven, the cloth attachment bar 21 is raised via the lifting frame 22 or the string-like transmission medium 24 (see FIG. 4), and the cloths 12, 12 are rolled up. Included spring 15
The vehicle travels in a downward direction against the The cake 27 separates from the cloth and falls at the point where the cloth 12 wraps around the lower guide roller 17. The cloth 12 is run until the cake-attached surface completely passes the guide roller 17. Next, when the driving device such as the hydraulic cylinder 23 or the driving roller 25 is driven in the opposite direction to the above and the cloth attachment bar 21 is lowered via the lifting frame 22 or the string-like transmission medium 24, the winding spring 15 is restored. The force causes the cloth 12 to be wound around the upper cloth winding roller 14 and run in the upward direction. At this time, the cloth 12 is cleaned by the spray pipe 19. Thereafter, the hydraulic cylinder 11 is operated in the opposite manner to the above to close the gaps between the plates 7, . . . , and the next process cycle begins. The upper winding roller 14 and lower guide roller 17 on which each cloth is stretched are installed on the upper bracket 13 and lower bracket 16 of each plate, so when opening and closing between the plates, each You can follow the board and move easily.

According to the present invention, the structure of the cloth section can be simplified, and since the cloth wrapping section is located above, the drawbacks of the conventional method can be eliminated, and it is compact and inexpensive, suitable for large-scale filter presses with many plates. Therefore, it is possible to provide a fabric traveling device that is flexible.
