Allow passage of the second material, foreign matter or wash water, or the like, or as shown in FIG. 4, the second material, foreign matter or wash water, etc. are formed through the groove 143 by forming a single or multiple grooves 143 on the outer circumference. You can let this go through.

When the flow rate adjustment shaft 140 is guided to the guide part 122 of the cleaning chamber 120, the sealing member 144 may be installed on the outer circumferential surface to maintain the sealing of the coupling part with the guide part 122. Alternatively, a sealing member (not shown) may be installed on the inner circumferential surface of the guide part 122 of the cleaning chamber 120.

The shaft moving driver 150 moves the flow regulating shaft 140 so that the flow regulating shaft 140 is inserted into or discharged from the discharge part 114. That is, the shaft movement driving unit 150 may adjust the opening and closing amount of the discharge unit 114 according to the degree to which the flow control shaft 140 is inserted into the discharge unit 114 by linearly reciprocating the flow control shaft 140. Further, the flow control shaft 140 is inserted into the discharge part 114 to remove foreign substances such as deposits or adsorbents attached to the inside of the discharge part 114.

The control unit 154 may control the driving of the motor 153 and the motor 153.

Here, the teeth 151 may be formed along the outer circumferential surface of the flow regulating shaft 140 and formed in a plurality along the longitudinal direction of the flow regulating shaft 140, thereby performing a function of a rack. . In addition, the pinion 152 may be directly connected to the motor 153 or may be rotated by the motor 153 by being connected through a reducer, a gear assembly, a belt, or the like. In addition, the motor 153 may be installed in the driving unit case 123 of the cleaning chamber 120, may be formed of a stepping motor or a servo motor to control the amount of rotation, and an encoder capable of measuring the amount of rotation may be used. . In addition, the control unit 154 receives the operation signal of the user, and controls the flow control shaft 140 to rotate the motor 153 by a predetermined amount to adjust the opening and closing degree of the discharge unit 114 to the degree corresponding to the operation signal. The motor 153 may be controlled to correspond to the movement amount of the preset flow control shaft 140 according to a preset time. Therefore, the opening and closing degree of the discharge part 114 is adjusted by adjusting the movement amount of the flow control shaft 140 by the user's operation, or the flow rate control shaft 140 is inserted into the discharge part 114 to discharge the discharge part 114. The foreign matter attached to the removal may be made, and furthermore, the foreign matter removal and cleaning of the discharge unit 114 may be performed every set time.

According to the cyclone 100 having a flow control and cleaning function according to the present invention, wastewater containing a mixture, for example sludge, is supplied to the separating body 110 through the supply port 111 in the interior space 112. In the circumferential direction in the second direction, the second material having a relatively high specific gravity, for example, the sludge moves out of the streamline by the centrifugal force in the direction of the wall of the inner space 112 to separate the descending portion 114 and the second outlet 121 downward. The first material, for example, the treated water, having a relatively small specific gravity, is discharged through the first outlet 113 along the upward flow of the center side.

As shown in FIG. 5, the tip 141 of the flow regulating shaft 140 blocks the discharge part 114 by moving the flow regulating shaft 140 by the driving of the shaft moving driver 150. It is possible to adjust the opening and closing amount of the discharge unit 114, which is a flow path for separating the second material, for example sludge, and to change the discharge and separation performance of the second material separated by adjusting the opening and closing amount of the discharge unit 114 Make this possible.

In addition, as illustrated in FIG. 6, the flow rate adjusting shaft 140 is inserted into the discharge part 114 by the driving of the shaft moving drive part 150, so that the discharge part 114 is formed by foreign matter such as sediment or adsorbate. In addition to preventing clogging, the washing water is supplied to the discharge part 114 side and the cleaning chamber 120 through the washing water inlet 130, thereby preventing the clogging and cleaning of the discharge part 114. This can increase the operation rate of the cyclone (100).
