The present invention relates to a device for removing foreign matter such as royal burlap, gravel, clay, and other miscellaneous trash from an influent of a water intake path, and can be installed at a raw water inlet of a water purification plant. The sedimentation tank 200 having the inlet 230 and the plurality of outflow holes 250 formed at one side of the rim is made of concrete, plastic, FRP or the like so that the inlet 230 So that the foreign matter is separated from the inflow water, and the separated inflow water is discharged through the outflow hole. Particularly, the inlet 230 coupled to the immersion tank 200 is eccentrically coupled to one side so that the inflow water enters the immersion tank 200 and is rotated to one side so that the immersion water can be quickly deposited by the cyclone effect do. A piston 410 for pushing foreign substances deposited on the upper part of the foreign matter extruding part 300 is installed in the upper part of the sedimentation tank 200 and the piston driving device for driving the piston 410 400 are installed on a plurality of pillars 500 erected on the periphery of the sedimentation tank 200.

The piston driving device 400 may be constructed by coupling the piston 410 to the rod of the hydraulic cylinder 450 using a hydraulic cylinder 450 as shown in FIGS. 1 and 2, 410 and may be configured to raise and lower the piston 410 by connecting the pinion gear to the end of the reduction gear and the reduction gear coupled to the rotation shaft of the motor and the motor, have.

When the bottom surface of the piston 410 is formed with a concave shape toward the center of the piston 410, the foreign material over the boundary surface of the piston 410 moves to the center of the piston 410 as the piston 410 advances, And the brush 420 is mounted around a certain portion of the lower end of the piston 410 so that foreign matter adhering to the mesh when the piston 410 passes through the first manhole cylinder 340 It is preferable to prevent the foreign matter from clogging the screen of the first manure cylinder.

The foreign substance extruding part 300 is configured such that the piston 410 is pushed and dropped to the upper part of the extrusion cylinder 310 so that the piston 410 can push the foreign substance to the lower part of the immersion tank 200, A first cylindrical manhole 340 formed of a net to discharge water contained in the foreign material to the outside, and water drained from the first manhole cylinder to the periphery of the first manhole cylinder and the extrusion cylinder 310 And a plurality of circulation spaces 360 configured to be connected to and discharged from the bottom of the sedimentation tank 200. The circulation space 360 is preferably divided into 3 to 6 parts around the extrusion cylinder 310 Do.

The extrusion cylinder 310, the first manhole cylinder 340, and the transfer tube 320 described below are preferably formed of stainless steel or plastic material which does not rust, and the first manhole cylinder 340 is formed by the outer wall of the cylinder, The outer diameter of the upper part of the extruding cylinder 310 is chamfered and the outer diameter of the upper part of the extruding cylinder 310 is larger than the diameter of the piston 410 and the diameter of the extruding cylinder 310 And a ring-shaped rim is formed at the lower end of the first manhole cylinder so as to be coupled with the extrusion cylinder 310 in a detachable manner.

Since the extrusion cylinder 310 must overcome the pressure and the load of the piston 410, a plurality of stud bolts or the like are coupled to the periphery of the cylinder so as to be firmly fixed to the partition wall between the circulation spaces 360.

When the extrusion cylinder 310 and the piston 410 have a large diameter difference, the extrusion cylinder 310 enters the cylinder and pushes the foreign substance to the transfer tube 320. Even if the piston 410 retreats, The foreign matter penetrated into the space between the piston 410 and the extrusion cylinder 310 may be reduced and the foreign matter may not be sucked into the gap between the piston 410 and the extrusion cylinder 310 when the piston 410 is lowered. If the difference between the diameters of the extrusion cylinder 310 and the piston 410 is small, there is a phenomenon in which the foreign substance pushed down by the transfer tube 320 is sucked up again when the piston 410 retreats A plurality of inflow holes 370 (inflow holes) are formed in the lower portion of the extrusion cylinder 310 so as to communicate with the circulation space 360. A shutter 380 hinged to the body of the extrusion cylinder is coupled to the inside of the inflow hole 370 so as to be opened and closed in accordance with the pressure so that the inflow hole 370 is closed to prevent foreign substances from leaking out when the piston comes down, It is preferable that the inflow hole 370 is opened to allow the water in the circulation space 360 to enter the inside of the extrusion cylinder 310 so as to fill the place where the piston is located to prevent the foreign matter from rising again.

A U-shaped transfer pipe 320 for discharging foreign substances pushed down by the cylinder to the outside is connected to the lower end of the extrusion cylinder 310 by welding or the like so that foreign matter is stored in the foreign matter reservoir 710 on the ground, .

The foreign matter introduced into the intake channel is mainly composed of Wanggorae, and the soil and other wastes are also introduced, but the shape is rough, so that the foreign matter pushed by the piston in the cylinder through the cylinder is wetted with water.

In order to discharge water to the outside from the foreign matter being conveyed through the transfer pipe 320, a cylindrical second manure cylinder 350 made of a net is installed at a portion where the transfer pipe 320 is raised in a "U & Dewatering is performed from the foreign matter before being discharged to the foreign matter discharge port 390, so that the burden of the foreign matter in the transportation of the foreign matter can be greatly reduced.

A water level sensor 600 is installed around the sedimentation tank 200. 1 and 2, the water level sensor 600 as an embodiment immerses the buoy in which the lever is coupled to the water introduced into the immersion tank, and when the immersion tank accumulates foreign matter in the lower part of the immersion tank and blocks the outflow hole 250, The lever connected to the buoy is raised, the button provided on the opposite side of the hinge coupled to the lever is pressed by the lever, the switch of the motor is turned ON, and the piston driving device When the piston 410 is moved down to the extruding cylinder 310 to push the foreign substance and the foreign substances accumulated in the outflow hole 250 collapse and the outflow hole 250 is opened, the amount of water drained increases, The water level sensor 600 may be configured to be a water level sensor of various known methods.

The operation of the foreign object removing apparatus according to the present invention will be described in order. When foreign matter removing apparatus is installed in the water intake path, power is applied to the piston driving apparatus 400 and the water level sensor 600, The foreign substances are immersed while being pushed into the center while the water is moved to the center and the water flows out of the sedimentation tank 200 through the outflow hole 250 And then proceeds to the purification plant through the outlet port 700.

When the level of the foreign object is accumulated due to the passage of time, foreign matter starts to block from the outflow hole 250 below the immersion tank 200, and when the level of the obstruction rises, the water level rises and the water level sensor 600 senses The piston driving device 400 is driven to push the foreign substances deposited in the lower part of the sedimentation tank to the extrusion cylinder 310. In the first operation cylinder 340, the water contained in the foreign matter is discharged through the mesh, The shutter 380 blocking the inflow hole 370 at the lower portion of the extrusion cylinder 310 is closed by the internal pressure of the piston 410 to prevent the foreign matter from leaking to allow the foreign matter to enter the transfer pipe 320 When the piston 410 is lowered to a certain depth, the advancing direction of the piston 410 is reversed and a vacuum is generated when the piston 410 is raised again. The shutter 380 at the lower portion of the extrusion cylinder 310 And circulates through the inflow hole 370 The water in the space 360 flows into the extrusion cylinder 310 and the piston 410 is moved to the outside of the immersion tank 200. At this time, The water level sensor 600 is in the "OFF" state and the piston driving device 400 is stopped. The foreign matter entering the transfer pipe 320 by the piston 410 moves toward the foreign matter discharge port by pushing out the foreign substance every time the piston 410 is operated, Dried in the semi-dried state, dropped into the foreign matter reservoir 710 through the foreign matter outlet port 390 of the transfer pipe 320, and taken out to the outside of the water treatment plant by the transfer means when a certain amount is collected.

According to the present invention, it is possible to increase or decrease the diameter of the extruded cylinder according to the size of the channel, but it is not possible to remove foreign substances larger than the diameter of the extruded cylinder. Therefore, the diameter of the extruded cylinder It is preferable to provide a separate screen capable of filtering foreign matter larger than the diameter of the extrusion cylinder if there is a possibility that a larger foreign matter may flow in.

The apparatus for removing dust on the intake duct of the present invention configured as described above allows the foreign matter to be deposited more quickly by adopting the cyclone system and is operated only when the foreign matter is immersed in the foreign matter more than a predetermined amount, Noise is not generated, water is discharged from the discharged foreign matter, the weight to be transported is reduced, and the size of the equipment is small, so that the facility area is reduced and the space utilization is high, thereby reducing the cost of removing foreign matter as a whole.
