Description

[Detailed description of the invention] This invention is based on a type of filter press in which a pair of cloth is wound up by a take-up roll provided at the bottom of a plate and then run when peeling the cake. Regarding improvement of the collecting device. In particular, this invention relates to an improvement to a cloth winding device in which a pair (two pieces) of cloth provided between each plate is wound into a single piece. It is an object of the present invention to provide a device that does not cause problems such as one side of the cloth sagging due to the difference in the top and bottom.

Hereinafter, this invention will be explained in detail with reference to the attached drawings. As shown in the figure, the structure is such that each board 1 is arranged in parallel in the horizontal direction so as to cover each side of the front and rear boards 1. In a filter press in which a pair of cloths 2, 2 are provided and the pair of cloths 2, 2 can run up and down, the cloths located on the front and rear surfaces of the plate 1, respectively, are placed on a pair of rolls provided at the bottom of the plate. 3, 3 are wound around each other, and the dirty surfaces are joined together, and the ends are fixed to a winding roll 4 provided at the bottom of the board 1, and one of the parallel boards 1 is attached. Every other board 1 is provided with a reversing device that rotates the winding roll 4 provided on the board 1 in a direction opposite to the winding direction of the winding rolls 4 before and after the winding roll 4. To explain the above correction device in detail, the one shown in FIG. 1 and FIG.
A counter shaft 5 is provided below the take-up roll 4 of every other plate 1, and the drive chain 7, which is hung on the sprocket 6 provided on this counter shaft, is hung on the sprocket 9 of the take-up roll shaft 8. The take-up roll 4 of the board 1 is reversely rotated with respect to the take-up roll 4 of the board 1. Also, in the one shown in Figure 3,
In order to drive the take-up roll 4 of every other board 1, the drive chain 7 is used as a sling, and the take-up roll 4 of the board 1 is reversed. Furthermore, in the one shown in FIG. 4, a reversing gear 10 is provided above the take-up roll 4 of every other plate 1, and is meshed with a drive gear 11 provided on the take-up roll shaft 8.
In the figure, reference numeral 12 is a drive shaft for the cloths 2, 2 provided above and along the row of plates, and 13 is a winding shaft for the cloths 2, 2 provided perpendicularly to the drive shaft 12. , a bevel gear 14 provided at the end of the hoisting shaft 1
It is meshed with a bevel gear 15 slidably provided at 3.

This device is constructed as described above, and after the dehydration is completed, the winding roll 4 opens the plate 1 and winds up the pair of cloths 2, 2 with their dirty sides stacked on top of each other.
Pull it down to the bottom of the plate 1, and put a pair of cloths 2, 2 on it.
In this invention, the winding rolls 4 provided on adjacent plates 1 are configured to rotate in opposite directions, so that the cake formed between the front and rear plates 1 is discharged. Since the pair of cloths 2, 2 located on the upper and lower sides of the winding rolls 4, 4 before and after being wound up respectively, one of the pair of cloths 2, 2 becomes slack and wrinkles occur during winding. There are no negative effects when 2 is broken. In other words, in a conventional pair of cloth winding rolls of this kind, the winding amount of the upper cloth is longer in circumference than the lower cloth by the thickness of the lower cloth. In order to prevent this, the slack was removed by a spring, and each pair of cloth was wound up separately, but this invention solved these problems with the conventional method. could be resolved all at once.
