Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
1 is an exploded perspective view of a screen-type foreign matter processor according to a preferred embodiment of the present invention.
1, the screen-type foreign matter processor according to the present invention includes a screw 100, a front screen 300, a rear screen 400, a front rotation assembly 500, and a rear rotation assembly 600 .
First, a screen 2 for blocking foreign matter from entering is installed at the end of the inflow pipe 1, and the screw 100 is installed horizontally on the inflow pipe 1 to discharge the foreign material to the outside.
The screw 100 is rotated through a driving motor 200 and a front screen 300 is installed on a front surface of the screw 100 and a rear screen 400 is installed on a rear surface of the screw 100.
The front screen 300 is a semicylindrical shape having a first through hole 302 and is installed in close contact with the front surface of the screw 100. The rear screen 400 is installed on the rear surface of the screw 100, Cylindrical shape corresponding to the front and rear screen 300, and a second through-hole 402 is formed.
The first through-hole 302 may be larger than the second through-hole 402, and foreign substances introduced through the first through-hole 302 may pass through the screw 100, This is to prevent the foreign matter that has been crushed due to the crushing through the rear screen from flowing backward.
Looking at the flow of water through the inlet pipe,
FIG. 2 is a cross-sectional view taken along the line A-A of FIG. 1, and FIG. 3 is a plan view of a screen-combined particle processing apparatus according to a preferred embodiment of the present invention.
As shown in FIG. 2, the water introduced through the primary screen 2 of the inlet pipe 1 passes through the front screen 300 through the front rotary assembly 500, which rotates first.
At this time, as shown in FIG. 3, foreign substances such as water are discharged to the side through the screw 100.
Therefore, a discharge pipe 700 which is in close contact with the side surface of the inflow pipe 1 should be formed at the end of the screw 100.
The water passing through the screw 100 passes through the rear screen 400 and the rear rotary assembly 600 and flows into the storage tank.
Here, the forward rotation assembly 500 and the rear rotation assembly 600 will be described in more detail.
A plurality of the front rotation assemblies 500 are installed adjacent to the front screen 300 so as to be rotatable at regular intervals and a plurality of rear rotation assemblies are installed adjacent to the rear screen 400 and rotatable at regular intervals do.
The front rotation assembly 500 and the rear rotation assembly 600 have protrusions formed on the outer circumferential surface to form a vortex around the rotation assembly through the protrusions (not shown in FIG. 1).
4 is an enlarged view of a portion B in Fig.
4, the front rotating assembly according to the present invention includes a plurality of rotating bodies 610 installed adjacent to the front screen 300, a blade 520 protruding from the outer circumferential surface of the rotating body 610, And a driving unit (not shown) for rotating the rotating body.
As described above, the protrusions 530 may protrude in the form of a straight line as shown in FIG. 4 and may be modified into various shapes capable of generating a vortex.
In addition, the end of the blade 520 is disposed adjacent to the front screen 300 so as to crush foreign substances introduced from the outside.
5 is a view showing a rear rotation assembly according to a preferred embodiment of the present invention.
5, the front rotating assembly 600 includes a plurality of rotating bodies 610 installed adjacent to the rear screen, a brush 620 protruding from the outer circumferential surface of the rotating body 610, And a driving unit (not shown) that rotates the motor 610.
5 (a), the brush 620 is brought into close contact with the rear screen to prevent foreign substances from being adsorbed on the rear surface of the rear screen. Similarly to the rear rotation assembly 600, the protrusion 630 is formed do.
5 (b), a fluid injection nozzle 640 is formed on the rotating body 610 so that foreign substances are adsorbed to the rear surface of the rear screen through air or water sprayed unlike the brush 620 .
The driving unit used in the forward rotation assembly and the rear rotation assembly may connect the driving motors to the plurality of assemblies, respectively, or may be connected to the driving motor for rotating the screw through shaft coupling.
As described above, according to the present invention, it is a principal technical idea to provide a screen-type foreign matter processor, and since the above-described embodiments are only one embodiment with reference to the drawings, the true scope of the present invention is determined by the claims .
