The present invention relates to a two-stage wastewater filtration device for filtering the insoluble mixture contained in the wastewater. Specifically, various undissolved foreign matters contained in the wastewater sprayed through the injection pipe are filtered through a filtering network and included in the foreign matter paper. Two-stage that transfers the foreign matter to the foreign matter storage container by squeezing the wastewater into the pressing roller and squeezes it out. It will be about wastewater filtration.

In general, a widely used wastewater filtration apparatus filters a mixture by simply installing a mesh frame on the outlet side of the wastewater filtration tank.

However, in the above method, a large amount of foreign substances are caught in the frame as time passes, and the foreign matter causes the filtration tank not to perform its functions properly, but rather blocks the inlet on the outlet side, thereby causing a drainage blockage. It happens.

Therefore, in order to prevent the drainage blockage, it is necessary to draw out the frame installed on the outlet side to the outside to remove the miscellaneous foreign substances hanging on the net, and then reinstall the frame. However, it is not easy to remove the foreign substances on the net. This operation must be repeated, which is accompanied by a lot of inconvenience.

In order to solve the above inconvenience, the invention provides a brush plate connected to the chain gear to the upper surface filtered by Patent Application No. 89-11467 so that the brush plate is transferred to the foreign matter storage container by dragging and moving the foreign matter caught on the upper surface of the filter plate. However, this invention also has a defect in that the function is somewhat reduced because the foreign matter caught in the filter plate is caught in the pores foreign matter is caught in the pores and the foreign matter stuck in the pores are discharged downward and discharged to the outlet.

The present invention is designed to solve the above-mentioned defects to drive the locking net to rotate and spray the waste water mixed with foreign matter to the injection pipe on the upper surface of the foreign matter is transported by the trapping net and the waste water is passed through the net lower So that the foreign matter is compressed into a compacting roller to form a lump, and the wastewater of the waste water container passes through the two-stage filtration system together with the fine foreign matter that has passed through the catching net so that the second foreign filtration device can be caught again. In order to prevent water pollution by flowing to the river through a well-drained drain pipe as described in detail below according to the accompanying drawings, both feed rollers (1) (2) and inclined rollers (3). The catching mesh 4 is wound around the outer periphery, and the crimping rollers 5 and 6 are positioned at the proper positions of the catching mesh 4. Pulleys 7 'formed on one side 5' of the roller 5 and one pulley 7 'formed on one shaft 2' of the transfer roller 2 and the pulley 9 of the motor 8 Are connected to each other by belts 10 and 11, and a two-stage filtration device 14 consisting of a mesh 12 and a drain pipe 13 at the lower portion of the compression roller 5 has a waste container 16 attached to the drain 15. ), A rubber material scrap (17) is attached to the outer circumference of the feed roller (2), and a cylinder (18) is attached to the shaft (3 ') of the tilt adjusting roller (3) to incline the catching net (4). And the injection pipe 19 is installed on the upper side of the feed roller (1), the tip of which is expanded to inject the waste water of the purification tank to the catching net (4), and the upper end of the pressing hole operated by the cylinder ( 21 is attached to the lower portion of the container 16 by installing a spray nozzle 22 to remove the foreign matter caught in the net body 4 to explain the effect of the present invention below the purification tank (not shown) The wastewater inside the sprayer is sprayed onto the roller (1) (2) and the inclined roller (3) by the catching net (4) which is rotated by the spray pipe (19) whose tip is extended by using the spraying device. The foreign matter present is transported along the catching net 4 and is compressed by the pressing rollers 5 and 6 being rotated on the upper and lower surfaces of the net 4.

The compressed foreign matter falls into a thin, flat mass and is transported to a foreign matter storage container (not shown), and the waste water from which the foreign matter has been removed falls into the waste water container 16 installed at the bottom through the mesh 4, but the waste water at this time. In the state that the foreign matter of the fine particles passing through the hole of the mesh 4 is mixed, this wastewater is discharged to the drain port 15 provided in the front of the container (16). At this time, in front of the drain 15, the drain pipe 13 is installed in the lower portion and the upper surface of the fine mesh 12 is formed on the network 12 of the two-stage filtration device 14, the waste water in the container 16 passes through the network ( 12) to filter out the fine foreign matter.

In such a state, the net body l2 is discharged to the drain water in a state in which the foreign matter is removed to the drain pipe 13 through the hole, and the foreign matter filtered in the net 12 is accumulated in the foreign matter storage container (not shown).

In addition, when pressing the foreign matter of the waste water in the pressing rollers (5) and (6), the foreign matter that does not fall into the holes of the net body (4) is meshed by a scrape (17) of rubber material installed at the bottom of the roller (2). The foreign substance stuck to the surface of (4) is removed and the foreign substance stuck in the hole of the mesh is still sprayed with the injection nozzle 22 to release the foreign substance stuck in the hole by the water spray pressure and re-transfer into the purification tank. .

If the locking net is rotated inclined slightly to one side without rotating to the right position on the surface of the roller (1) and (2) during use as described above, the tilt adjusting roller (3) installed in contact with the lower side of the locking net (4) is inclined. In the opposite direction to prevent the catch network 4 is inclined to be transported in this case, the inclination of the rotary roller 3 for adjusting the inclination to adjust the inclination by operating the cylinder 18 attached to one side (3 ') will be.

If the work continues as described above, since the location of the waste water sprayed onto the catching net 4 is constant, a large amount of foreign matter may accumulate in some cases. In this case, the spraying position of the spray pipe 19 should be adjusted. The control of the injection position is adjusted to the flow rate of the flow rate by pressing the injection port 21 installed in the upper part of the injection pipe 19 to the lower by the operation of the cylinder 20 to compress the injection pipe 19 to the injection pipe ( By allowing the water to be sprayed farther from 19), it is easy to remove foreign substances and waste water easily.

The device of the present invention having the above function is easy to use and can completely filter even the finest foreign matter.
