製造したものである。 Belt filters are used in the manufacturing process of uranium dioxide powder, which is a raw material for nuclear power generation reactor fuel. Uranium dioxide powder is produced by heating solid uranium hexafluoride (UF 6 ), contacting pure water with this UF 6 to hydrolyze it to form an aqueous solution of uranyl fluoride (UO 2 F 2 ), and adding ammonia to this aqueous solution. Water is added to form a precipitate of ammonium deuterate (ADU), and a liquid (slurry) containing this ADU precipitate is created.
The resulting precipitate (cake) is washed, dried, and pulverized, and the resulting ADU powder is roasted and reduced.

給されるようになつている。 The belt filter is constructed as shown in FIG. That is, a porous rubber belt 3 and a filter cloth 4 are wound around the drive drum 1 and the table drum 2. This filter cloth 4 is attached to tension rollers 5 and 6.
The filter cloth is stretched tightly and rotatably on the rubber belt 3 via a meandering adjustment roller 7, an auxiliary roller 8, and a filter cloth tensioning adjuster 9. When the ADU slurry 10 is supplied onto the filter cloth 4 through the pipe 11, washing water is supplied from the pipe 12, and ammonium fluoride in the ADU slurry 10 is removed by this washing water. ADU slurry 1 on filter cloth 4
0 is dehydrated through a filter cloth 4, a rubber belt 3, and a drain pipe 14 having a large number of pores 13 to form a wet cake 15 with a water content of 30% to 40%, and this wet cake 15 is scraped with a scraper 16. It is dropped and supplied to a dryer (not shown) for the next process through a hopper 17.

きものは末だ開発されていないのが実情である。 However, in such a conventional belt filter, the width of the filter cloth 4 is several tens of centimeters or more, and the distance between the drive drum 1 and the tail drum 2 is more than 10 meters, so the filter cloth 4 is not easily moved in its width direction during operation. Sometimes they shifted to one side or gathered in the center, causing wrinkles. If the filter cloth 4 is lopsided, the ADU
Since there are parts where the slurry 10 is not placed on the filter cloth 4,
ADU slurry 10 is dissipated. For this reason, during operation of the belt filter, constant care must be taken to ensure that the filter cloth does not shift to one side, and if even the slightest abnormality occurs, it must be corrected using the meandering adjustment roller 7. In addition, this meandering of the filter cloth 4
There was a problem that it was difficult to check when wrinkles appeared. In addition, if the filter cloths 4 are moved toward the center of each other and wrinkled, the ADU slurry 10 placed on the wrinkled area will not be sufficiently cleaned and dehydrated, and the ADU slurry 10 placed on the wrinkled area will
However, there was a problem in that the scraper 16 could not scrape off the filter cloth 4, and the life of the filter cloth 4 was shortened. Therefore, it has been desired to develop a wrinkle removing correction device for the filter cloth 4, but the wrinkle removing correction devices that have been devised so far require special power, are large, or have insufficient functionality. The reality is that we have not yet developed anything that would satisfy us.

In belt filters that continuously remove moisture from slurry supplied onto rubber belts and filter cloth,
Both sides in the width direction of the filter cloth located between the tail drum and the tension roller are held by holding rollers, and the axial direction of these holding rollers is set to the filter at the holding part by the holding rollers with respect to the width direction of the filter cloth. By making the angle adjustable in the direction in which the cloth travels, it is possible to easily and reliably remove wrinkles from the filter cloth without using special power or large equipment, and it is also possible to check the meandering of the filter cloth. becomes easier,
It is an object of the present invention to provide a wrinkle removing machine for a filter cloth of a belt filter that can quickly correct the meandering of the filter cloth.
