The present invention relates to a variable filtration apparatus capable of adjusting the thickness of the filtrate, and more particularly, in the construction of a filtration apparatus used for improving the quality of the final effluent water in a high-treatment wastewater or sludge treatment, The present invention relates to a variable filtration device capable of controlling the thickness of the filtration layer so that the thickness of the effluent can be filtered by controlling the thickness of the effluent by allowing the variable thickness to be controlled in a relatively simple manner and stably operating the filtration layer.

Among various environmental problems caused by the development of industrial society and the expansion of urban areas, water pollution problem is emerging as one of the important factors that can threaten the future of mankind. In order to solve this problem, the limit of pollutant emission standards has been strengthened, and biological or physicochemical advanced treatment facilities have been expanded. In particular, various types of filtration apparatuses for improving the quality of the final effluent in advanced waste treatment facilities This has been proposed and used.

On the other hand, the present inventor has proposed a technique for improving the problems of the prior art of controlling the filter pores by compressing the fiber yarn through the Republic of Korea Patent Application No. 10-2009-0079783 "variable filtration device".

1 is a view for explaining a variable filtration device proposed by the inventor through the prior application.

Referring to FIG. 1, the variable filtration device 500 proposed by the present inventors includes a filtration tank 510, a filtration unit 520, a winding unit 530, and a filter cloth 501.

At this time, the filtration unit 520 is provided with a chamber 522 is formed around the filtration hole 523 to allow the filtration channel 521 to communicate with the outside, the chamber 522 is the cavity of the filtration tank 510 Located in 511, the chamber 522 is installed in the filtration tank 510 so as to be rotatable in a predetermined direction by an external driving force. In addition, the filtration unit 520 is coupled to one side of the chamber 522 and extends to the outside of the filtration tank 510, so that the rotation shaft 526 is connected to an actuator installed outside the cavity 511, and the rotation shaft ( A discharge shaft 524 that is coupled to the other side of the chamber 522 on the opposite side of the 526 and extends out of the filtration tank 510 to communicate with the filtration channel 521 of the chamber 522 to form a discharge passage for the filtered water. Has

In addition, the winding unit 530 has a roller 532 arranged to correspond to the chamber 522 of the filtration unit 520 in the cavity 511 of the filtration tank 510, and extends outwardly from the roller 532. It is connected to an actuator installed outside the cavity 511 through the rotating shaft 534 is rotated in conjunction with the above-described filtration unit 520.

The variable filtration apparatus 500 having such a configuration controls the number of windings of the filter cloth 501 wound on the chamber 522 of the filtration unit 520 to change the thickness of the filtrate, thereby allowing the cavity 511 of the filtration tank 510 to be changed. The inflow water accommodated in) is filtered by the filter cloth 501, and the filtered water contained in the filtered water passage 521 of the chamber 522 is discharged to the outside.

A driven sprocket 94 is provided to connect the drive sprocket 92 and the driven sprocket 94 with a chain 96. At this time, the pin 96, which is moved along the chain 96 is fixed to the chain 96, the pin 98 to adjust the position as necessary. In addition, a sensor for detecting the maximum winding position on the side of the chamber 32 so as to correspond to the position where the filter medium 1 is wound around the chamber 32 and the maximum wound on the roller 52 in the movement path of the chain 96. The sensor 110 which detects the maximum winding position of the 100 and the roller 52 side is provided. Of course, the two sensors 100 and 110 are supported by brackets 102 and 112 whose positions are adjustable.

As shown in FIG. 9, in the variable filtration apparatus 10 which can adjust the filtrate thickness according to the present embodiment by the detection unit 70 as described above, the filter media 1 is positioned at the maximum wound on the chamber 32 side. By detecting the coming and coming to the position of the maximum winding on the roller 52, the movement of the medium 1 is controlled by the detection signal input from the detection unit 70 through the control unit 150. That is, as shown in (a) of FIG. 9, when the media 1 is completely wound on the roller 52 to the initial setting position, a rotation counting module for detecting the rotation speed of the chamber 32 ( The sensor 86 of the 80 is set at the position where the pin 84 is detected, and the pin 98 of the position counting module 90 indicating the position of the media 1 has a maximum wound position on the roller 52 side. It is set at the position detected by the sensor 110 to detect. In this state, if the final winding position set for control when the media 1 is wound up to the chamber 32 at the time of the process is set as shown in FIG. 9B, the controller 150 counts the position counting. When the pin 98 of the module 90 is detected by the sensor 100 to detect the maximum winding position on the chamber 32 side, the operation of the motor 41 is stopped.

As described above, the variable filtration apparatus 10 capable of adjusting the thickness of the filtrate may detect the position and the number of turns of the media 1 by combining the position counting module 90 and the rotation counting module 80.
