The pipe part 310 may accommodate the filling part 320 . The pipe part 310 may include a first insertion hole 317 into which the lower end of the drug injection pipe 330 is inserted. The first insertion hole 317 may be formed in the upper surface of the pipe part 310 so that the drug injection pipe 330 is stably inserted and the drug refill is easily performed.

The pipe part 310 may include a first adapter 311 and a second adapter 312 . For example, in the piping unit 310, the first adapter 311 is coupled to one side in a state in which the filling unit 320 and the filter unit 330 are accommodated, and the second adapter 312 is coupled to the other side. have. For example, the pipe part 310 and the first adapter 311 , and the pipe part 310 and the second adapter 312 may be coupled by thermal fusion in a state in which the filling part 320 is accommodated, respectively.

The first adapter 311 may include an inlet 311a through which raw water is introduced. Raw water introduced from the aeration tank may be introduced into the inlet 311a. For example, the first adapter 311 may be coupled to the settling pipe by a fitting defect or a screw coupling. To this end, the first adapter 311 may include a plurality of first connection holes 313 . The plurality of first connection holes 313 may be formed to be spaced apart from each other along the circumferential direction of the first adapter 311 .

The second adapter 312 may include an outlet 312a through which raw water is discharged. The secondary wastewater flowing in from the settling tank may move to the discharge pipe through the outlet 312a. For example, the discharge pipe may be coupled to the second adapter 312 by a fitting defect or a screw coupling. To this end, the second adapter 312 may include a plurality of second connection holes 314 . The plurality of second connection holes 312 may be formed to be spaced apart from each other along the circumferential direction of the first adapter 314 .

The second adapter 312 may include a support jaw 315 . The supporting jaw 314 may protrude from the outlet 312a in the inner direction of the pipe part 310 and may come into contact with the filling part 320 .

At this time, the filling body 321 may include a second insertion hole 328 into which the lower end of the drug injection pipe 330 is inserted. The drug injection pipe 330 is stably inserted into the second insertion hole 328 , and may be formed on one upper surface of the filling body 321 so that the drug refill is easily performed.

In addition, the filling body portion 321 may be formed with a first through hole (321a) on the outer surface. The first through-holes 321a may be formed in plurality, and the plurality of first through-holes 321a may be spaced apart from each other in the extending direction of the filling body 321 . The water introduced into the pipe portion 310 passes through the first through hole 321a and flows into the filling body portion 321 filled with the purifying agent, and at this time, the first through hole 321a By changing the hydraulic pressure and flow rate of water according to the shape, it is possible to control the speed and time at which water and purification chemicals are mixed. For example, the first through hole 321a is formed so that the penetrated width W is gradually widened or narrowed toward the inner side of the filling body 321, thereby changing the hydraulic pressure and flow rate of water to mix water and purifying chemicals. You can control the speed and time. At this time, the water introduced into the pipe part 310 may permeate into the filling part 320 through the first through hole 321a, and may dissolve the purifying agent filled in the filling part 320 .

The dissolved purifying agent stays inside the filling part 320 , and naturally leaks out of the filling part 320 by the pressure difference when water rapidly flows out of the filling part 320 . In addition, the liquid purification agent can be readily dissolved in water. For example, when the purifying agent is in a solid state, dissolution of the purifying agent may not be performed properly. Therefore, as the number of the first through-holes 321a increases, the area in which water comes into contact with the purification agent increases, so that the cleaning agent can be dissolved smoothly.

The cover part 327 may be formed on one side of the filling body part 321 in a state in which the filling agent is filled in the filling body part 321 and may be coupled to an opening serving as an inlet so that the filling agent may be filled. In this case, a second through hole 327a may be formed on one surface of the cover part 327 . For example, one or more second through-holes 327a may be formed in the center of the upper surface of the cover part 327 . For example, the filling body portion 321 and the cover portion 327 may be coupled by screwing to block the opening of the filling body portion 321 .

A first guide blade 323 is formed on the outer surface of the filling part 320 , and a diamond powder 325 may be coupled between the first guide blade 323 and the adjacent first guide blade 323 .

The first guide blade 323 may be formed along the circumferential direction of the filling part 320 . In addition, each of the plurality of first guide blades 323 may be in close contact with the inner surface of the pipe unit 310 , and accordingly, the water introduced through the inlet 311a of the pipe unit 310 is discharged from the first guide blade 323 . ) can be discharged while rotating by

The line mixer 300 according to an embodiment of the present invention has a cross-sectional area of a path through which water formed between the pipe part 310 and the filling body part 321 through a plurality of first guide blades 323 can flow.

In addition, since the plurality of first guide wings 323 are formed on the outer surface of the filling part 320 , the flow and flow of water may be changed. At this time, a turbulent flow may be achieved in the vicinity where the first guide blade 323 is formed. For example, the filling agent is dissolved in water in the inside of the pipe part 310, but some may exist in a lumped state in the water. Therefore, in a state in which the filling chemical is lumped, it can be discharged to the outlet 312a as it is by riding the flow of water introduced into the pipe part 310 . At this time, the filling agent agglomerated by the turbulent flow in the vicinity of which the first guide blade 323 is formed may be more finely dissolved in water.

A plurality of diamond powders 325 may be coupled between the first guide blade 323 and the adjacent first guide blade 323 . For example, the diamond powder 325 may be small diamond grains. The diamond powder 325 may be coupled to the side of the filling part 320 and the flowing water may be sterilized or antibacterial. For example, a coupling groove to which the concavely formed diamond powder 325 is coupled may be formed in the filling part 320 . The diamond powder 325 may be positioned in the coupling groove, and the filling part 320 and the diamond powder 325 may be connected via glue. As another example, the diamond powder 325 may be coupled to the outer surface of the filling part 320 by heating a part of the filling case and pressing the diamond powder 325 .

The line mixer 300 according to an embodiment of the present invention spatially separates the space where the filling chemicals are filled and the water so that when water flows into the line mixer, it does not come into contact with the filling chemicals immediately, so that the filling chemicals are caused by water. It is possible to increase the dissolution time, thereby preventing the filling agent from being quickly consumed.
