More particularly, the present invention relates to a scum removing device for an agitator which is capable of stirring a mixed solution in a stirring tank, And an agitator for water treatment using the same.

Generally, the coagulant is added to remove the contaminants in the water during the water treatment process. In this process, flocs and scum are generated in the admixture, floc-forming paper (coagulant paper) and sedimentation paper. In addition, scum is inevitably generated in sedimentation basin even when biological treatment of sewage or sewage is performed.

Such scum is a lighter weight than water, and floats on the surface of a stirring tank such as a mixed paper, a coagulating paper, a settling paper, etc. containing water.

A scum removing device having a plurality of scum blades is used to remove scum floating on the water surface of the stirring tank. Since the scum removing device is not freely adjustable in height, it can not cope with fluctuations in the water level of the stirring tank There is a problem.

That is, in order to remove the scum floated on the water surface of the stirring tank with the scum blades, the scum blades should be positioned near the water surface together with the scum, but when the water level of the stirring tank is formed higher or lower than the position of the scum blades, There is a problem that the scum floated on the water surface can not be effectively removed by using the blade.

1 to 11, the operation and effect of the scum removing device for a stirrer according to the present invention and the water treatment stirrer using the same will be described.

Referring to FIGS. 1 to 11, in the water treatment stirrer according to the present invention, any one of rotational forces separated by at least two by the speed reducer 120 is output through the second shaft 140, and the impeller 150 The mixed liquid in the stirring tank 200 is stirred.

At the same time, in the case of a scum floating on the surface of the mixed liquid filled in the stirring tank 200, a rotational force output through the first shaft 130 among the rotational forces separated by the speed reducer 120 by at least two The flocculant scum blades 1621 and 1622 always float along the guide unit 161 while being interlocked with the level of the mixed solution filled in the stirrer 200 while being transmitted through the guide unit 161 and rotated, So that it is possible to always provide the best scum removing effect irrespective of the level of the mixed liquid filled in the stirring tank 200.

That is, in the case of a scum removing device installed in a general water treatment stirrer, the scum removing device is installed in the water treatment stirrer in a fixed form without ascending or descending according to the level of the mixed solution filled in the stirring tank. Therefore, when the scum removing device is located on the water surface of the mixed liquid filled in the stirring tank or below the water surface, the scum removing effect by the scum removing device is very small due to the characteristics of the scum floating on the water surface have.

In contrast, in the case of the water treatment stirrer according to the present invention, even if the level of the mixed solution filled in the stirring tank 200 varies, the scum bladder unit 162 is buoyant depending on the level of the mixed solution filled in the stirring tank 200, The buoyancy scream blades 1621 and 1622 are always positioned on the water surface irrespective of the level of the mixed liquid which is raised and lowered along the guide unit 161 and filled in the stirring tank 200.

Although the scum blade unit 162 is moved up and down along the guide unit 161 by buoyancy depending on the level of the mixed liquid filled in the stirring tank 200, The rotational force of the decelerator 120 can be stably supplied to the scum blades 1621 and 1622 regardless of the position of the scum blade unit 162 by applying a rotational force to the buoyancy box 1627 and the scum blades 1621 and 1622 by the bar 1611. [ (162) to rotate the scum blades.

Therefore, the water treatment stirrer according to the present invention can always maintain a uniform scum removing efficiency regardless of the level of the mixed solution filled in the stirring tank 200 even if the level of the mixed solution filled in the stirring tank 200 is changed There are advantages.

In addition, the water treatment stirrer according to the present invention removes the scum floated on the surface of the mixed solution by the buoyancy scum blades 1621 and 1622, and the buoyancy scum blades 1621 and 1622 rotate, The scum attached to the inner wall of the stirring tank 200 can be removed by the scraper 1625 provided in the scum blades 1621 and 1622 to further improve scum removing efficiency.

As described above, the apparatus for removing scum for a stirrer according to the present invention and the stirrer for water treatment using the same are provided with at least one impeller 150 rotated by the second shaft 140 connected to the speed reducer 120, The scum blade unit 162 is lifted and lowered along the guide unit 161 with the water level of the mixed liquid by buoyancy regardless of the level of the mixed liquid in the stirring tank 200, The scum floating on the surface of the mixed liquid is always removed in a state in which the first and second screeds 1621 and 1622 are always located on the surface of the water so that constant scum removing efficiency can be always provided.

Further, the floating scum blades 1621 and 1622 are rotated to remove the scum floating on the water surface of the mixed solution, and the scum attached to the inner wall of the stirring tank 200 can be removed, thereby further improving the water treatment efficiency .

While the present invention has been described in connection with what is presently considered to be practical and exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
