Accordingly, during the process of the lower and wastewater being transferred from one side of the fluid pipe 500 to the other side, the strainer passes through the strainer, and the impurities mixed in the lower and the wastewater are collected by the mesh screen 110 of the mesh screen body 121 A phenomenon of blocking the mesh screen 110 occurs and is removed by the obstacle removing plate 150 and collected in the contaminant storage unit 300 located at the lower end of the mesh screen 110. A sensor Open to allow the contaminants to drain.

The mesh screen body 121 of the present invention has a "C" shape so that the mesh screen 110 formed on the mesh screen body 121 also has a "C" shape and corresponds to the inlet of the fluid pipe 500, So that the volume of the fluid flowing through the fluid pipe 500 and the amount of the fluid passing through the mesh screen 110 are the same.

The upper fixing pin 130 and the lower fixing pin 140 shown in FIG. 4 are stopped when the contaminant removing plate 150 is pressed against the lower fixing pin 140 located under the strainer during operation of the driving motor 200 And the uprising stops when the contaminant removing plate 150 is conveyed upward and the upper fixing pin 130 is pressed.

The driving motor 200 used in the present invention stops the motion of the driving motor 200 when it is hooked on the upper fixing pin when it is transferred to the upper portion of the obstacle removing plate by using the forward and reverse motors, and the obstacle removing plate is lowered to be fixed when the lower fixing pin is hooked.

FIG. 5 is a side view of the mesh screen of the mesh screen body according to the present invention, showing the operation state of the mesh screen of the present invention in order to remove contaminants from the mesh screens of the mesh screen body of the present invention, ) To protrude so as to correspond to both side end portions of the " C " -shaped mesh screen body 121), so that the contaminant removal plate is allowed to perform vertical movement without being rotated when lifted and lowered by rotation of the drive shaft.

That is, the rotary motion of the driving shaft is converted to vertical motion so as to move up and down along the screw of the driving shaft without being rotated by making the clog removal plate fixing pin 153 correspond to both side end portions of the mesh screen body 121.

According to the present invention as described above, it is possible to automatically remove the contaminants from the strainer when the waste water and wastewater are discharged, and to discharge the discharged contaminants automatically by opening the drain valve. Thus, In order to prevent clogging and failure of the pumps and various unit devices due to impurities (foreign substances) present in the wastewater during transportation of food wastes and livestock manure that are generated, pressure is applied to the front and rear ends of the strainer installed at one side of the wastewater transfer pipe If a difference occurs, it is possible to automatically remove the impurities without stopping the existing operation.

Further, the present invention provides a self-blocking automatic strainer, which enables stable operation without stopping the operation of the water treatment apparatus in the continuous operation process.
