Detailed Description of the Invention [Industrial applications]

TECHNICAL FIELD The present invention relates to a filtering device including at least two filtering units capable of performing filtration by closing a tubular filter medium in a bag shape and then supplying a stock solution into the filter medium.

[Prior art]

As a conventional filtering device, for example, there is one that is provided with only one of the above filtering units and is operated by repeatedly operating the filtering unit. In addition, as this filtration unit, for example, after closing the lower end opening of the tubular filter medium, the undiluted solution is supplied from the upper end opening to perform filtration, and after the filtration is completed, the lower end opening of the filter medium is opened to open the filter medium. There is one configured to discharge the cake inside.

[Problems to be Solved by the Invention]

However, the above-mentioned conventional filtering device is provided with only one of the above filtering units, and in this one filtering unit, after closing the lower end opening of the tubular filter medium and after finishing the filtration, Before performing the filtering operation of
Since it takes a predetermined time to discharge the cake in the filter material and prepare for the next filtering operation, there is a problem that the efficiency of the filtering device is poor. Further, in the conventional filtering device, in the above filtering unit, when the cake is discharged, the opening at the lower end of the filter medium is simply opened, so that there is a problem that the cake attached to the filter medium cannot be discharged. In order to solve this problem, vibration may be manually applied to the filter medium, but there is a problem that the vibration applying work is complicated and it is difficult to apply vibration to the entire filter medium with a large-sized filtration device. . Therefore, an object of the present invention is to solve the above-mentioned problems, and it is possible to perform more efficient operation of the entire apparatus as compared with the conventional filtration apparatus, and moreover, to smoothly discharge the cake from the filter medium. It is to provide a filtration device equipped with a filtration unit capable of

Do it. Further, in the filtration device according to the present invention, in each of the filtration units, after closing the lower end opening of the filter medium with the closing member, the raw solution is introduced into the filter medium from the upper end opening of the filter medium by the raw solution supply device. Feed and filter. After the completion of filtration, the opening of the lower end portion of the filter medium is opened by driving the blocking member, and the cake held in the filter medium is discharged. At the time of discharging the cake, the vibration applying member applies vibration to the filter medium to discharge the cake attached to the filter medium.

【The invention's effect】

According to the filtration device of the present invention, by operating the above-mentioned at least two filtration units simultaneously or one by one, the filtration processing amount of the entire device is increased at least twice as compared with the conventional filtration device, and more It enables efficient driving and is therefore more economical. Therefore, when the at least two filtration units are repeatedly operated one by one, it is possible to prepare the other filtration units for the next filtration operation while one filtration unit is performing the filtration operation. When the filtering is completed in one filtering unit, the other filtering units can be made to perform the filtering operation immediately. Therefore, the filter device can be operated with almost no downtime. Therefore, the filtration cycle from the time when the first filtration operation is performed to the time when the next filtration operation is performed in the entire apparatus can be made faster than in the conventional case. Further, when the at least two filtration units are operated at the same time, the filtration processing amount by one filtration operation is at least twice as large as that of the conventional filtration device. Therefore, according to the filtration device of the present invention, The time required for the amount of filtration to reach the predetermined amount can be shortened as compared with the case of using the conventional filtration device. Further, in each of the above filtration units, when the cake is discharged, vibration can be applied to the filter medium by the vibration imparting member, so that the cake adhering to the filter medium can also be separated from the filter medium and smoothly discharged. The discharge efficiency can be improved. Further, the filter chamber composed of the above-mentioned tubular filter medium has an effective filtration area in the entire circumference of the filter chamber as compared with the filter chamber formed between a pair of filter cloths arranged between the adjacent filter plates. In addition, since the shape of the filter chamber can be changed freely, it has a large degree of freedom, it has various effects such as easy swinging of the filter medium as a whole, and the cake is easily separated from the filter medium. The filtration efficiency can be greatly improved as compared with the device.
