Description

[Detailed Description of the Invention] [Technical Field of the Invention] As mentioned above, this invention relates to a long-hair filter cloth length adjustment tool in a long-hair filter machine, and more specifically, to easily adjust the length of the long-hair filter cloth. This invention relates to a tool for adjusting the length of long wool filter cloth.

[Prior art]

Conventionally, the long-hair filter cloth fitted into the filtration drum of long-hair filters stretches due to the action of water etc. during the filtration of raw water, and using it in such conditions can cause damage to the long-hair filter cloth. Therefore, the length of the filter cloth has been adjusted using a length adjusting means.

Conventional length adjustment means for filter cloth include, for example, inserting a long-hair filter cloth into a so-called dovetail-shaped recess formed in the rim of a filter drum while pulling it, and then firmly fitting a vinylon rope or rubber rope into it. It is fixed with.

However, with such conventional length adjustment means, when adjusting the length of the long-hair filter cloth, it is necessary to pull out the vinylon rope or rubber rope from the dovetail-shaped recess formed in the rim and reinstall the long-hair filter cloth. However, there were problems in that it required a lot of effort and time, required skill, and was likely to damage the long wool filter cloth.

[Purpose of invention]

This invention was devised by focusing on the conventional problems, and its purpose is to allow anyone to adjust the length of the long wool filter cloth in multiple stages in a short time with easy operation. To provide a tool for adjusting the length of a long-hair filter cloth in a long-hair filter, which can perform the length adjustment without damaging the long-hair filter cloth.

[Structure of the idea]

In order to achieve the above-mentioned purpose, this invention is a long-hair filter length adjustment device that adjusts the length of the long-hair filter cloth fitted on the filter drum using an adjustment tool provided on the rib part of the filter drum. The gist of the filter drum is that the rim portion of the filter drum is provided with a multi-stage recess and a length-adjustable holding member that engages with the recess.

[Example of idea]

Embodiments of this invention will be described below based on the accompanying drawings.

FIG. 1 shows a schematic diagram of a long-hair filter 1 implementing this invention, in which 2 is a raw water tank equipped with a supply port 3 for raw water W (industrial water, sludge water, etc.), and 4 is a raw water tank 2.
A rotatable filtration drum disposed inside,
A long wool filter cloth 5 previously formed into a cylindrical shape is fitted around the outer periphery of the filter drum 2 .

The long hair filter cloth 5 is fixed to the outer peripheral surface of the filter drum 4 by a length adjuster 7 provided on the rim portion 6 of the filter drum 4.

As shown in FIG. 2, the length adjuster 7 includes a multi-shaped (two-stage) recess 8 formed in the rim portion 6 of the filter drum 4, and a length-adjustable presser foot that engages with the recess 8. It is composed of a member 9.

The holding member 9 is composed of a holding plate 11 having a long hole 10, a stud bolt 12 and a spring-loaded nut 13 that are inserted into the long hole 10 of the holding plate 11 and tightened in the recess 8 of the rim portion 6. has been done. The tip 11a of the presser plate 11 is formed into a substantially L-shape so that it can easily engage with the recess 8, and the length of the elongated hole 10 is such that the tip 11a of the presser plate 11 can be easily engaged with the recess 8.
1a is formed to a length that can be engaged with.

In addition, in FIG. 1, 14 is a backwash hopper, W
2 is treated water, and 15 is a rotational drive mechanism for the filter drum 4.

Next, the second method for adjusting the length of the long hair filter cloth 5 will be explained.
This will be explained with reference to FIGS.

First, FIG. 2 shows the state of the long-hair filter cloth 5 before its elongation has been corrected, and if the long-hair filter cloth 5 has elongated slightly in such a state and needs to be corrected, the spring-loaded nut of the stud bolt 12 should be tightened. Loosen 13. Then, the holding plate 11 is slid toward the recess 8 along the stud bolt 12 inserted through the elongated hole 10, and while it is positioned at the first step 8a of the recess 8, the spring-loaded nut 13 is tightened. As a result, the tip 1 of the presser plate 11
1a is pressed against the first stage 8a of the recess 8, and at the same time, the long wool filter cloth 5 stretched is also pressed against the first stage 8a of the recess 8.
It is pulled into the inside of a and eliminates slack.

If the correction of the long-hair filter cloth 5 cannot be corrected by pulling only the first stage 8a, slide the presser plate 11 up to the second stage 8b by the same operation as described above, as shown in Fig. 4. Fix it. Thereby, the extended length of the long wool filter cloth 5 can be easily corrected.

In this embodiment, the recess 8 has two stages, but the number of stages is not limited to this, and it is also possible to increase the number of stages. In this case, the presser plate 1
It is also necessary to adjust the length of the elongated hole 10.

This invention is a long wool filter cloth length adjusting device that adjusts the length of the long wool filter cloth fitted on the filter drum as described above using an adjustment tool provided on the rib portion of the filter drum. Since the rim portion of the filter drum is provided with a multi-stage recess and a length-adjustable holding member that engages with the recess, the elongation of the long filter cloth can be easily corrected in a short time. Also, anyone can easily do it, as there is no need to be an expert.

Furthermore, since there is no need to remove the long-hair filter cloth during correction, the long-hair filter cloth will not be damaged.

Moreover, since the structure is simple, it can be manufactured at low cost.
