The present invention relates to a composite integrated lower collecting device, and in particular, a forming plate combined with a plurality of strainer fixing tube on the support portion installed in the filtration tank, and after pouring and curing the concrete slab thereon, a plurality of strainer fixing tube is combined A plurality of catching blocks formed in the catcher area in the catching area to prevent the adverse effects of the shooters are installed on the concrete slab vertically and horizontally to fix them with mortar filling, and the strainer is fixed to the strainer fixing tube communicating with the concrete slab and the catching block. Combining the lower collecting layer, the integrated integrated lower collecting unit solves the horizontal problem of the filtration block, the mortar detachment problem and the anchoring problem and prevents the adverse effect of the shooter. Relates to a device.

In general, the filter paper is formed by dividing the filter tank on both sides by the inner and outer walls of the reinforced concrete wall, and a lower collecting chamber is formed at the lower part of the filtering area in which the filter medium layer is formed.

One side of the filtration tank is formed with a raw water inlet and raw water inlet wear, an inlet valve is installed between the raw water inlet and the raw water inlet wear, the raw water distributor is formed on the side wall of the filtration tank to distribute the raw water.

In the middle part of both filtration tanks, a water purifier is provided in the lower part between both inner walls, the back washing water withdrawal tank is formed in the upper part of the water purifier, and the water purification outlet and the air communication hole are formed in the both sides of the water purifier.

A bottom of the raw water inlet provided on one side of the filtration tank is formed with a discharge tank, and a discharge valve is coupled between the discharge tank and the backwash water discharge tank.

And, the lower portion of both of the filter paper of the filter paper is formed with the support beam integrally with the wall at regular intervals, a plurality of filter blocks are assembled on the support beam, the strainer is coupled to each filter block.

Such a conventional filter paper is inflowed evenly by each filter paper which is operated in parallel through the raw water inlet, the inlet valve, and the raw water inlet ware, and the raw water is the filter medium laminated in the filtration area of the filtration tank through the raw water distributor. Flows into the top of the bed.

The inflowed raw water passes through the filter material layer on which the filter sand and gravel are stacked to remove the suspended substances, and the filtered water is introduced into the lower collection chamber under the filter tank and collected by the purified water outlet through the purified water outlet. Discharged.

As this filtering action is repeated, the filtration power of the filter medium layer is reduced, the filtration is stopped and washed. Such washing has a great effect on the filtration power, so that an equal and effective washing should be performed throughout the filtration tank.

When backwashing the filter media layer, the water-air type is supplied to the water purification unit by the air supply means and then flows into the lower collection chambers of both filter tanks through the plurality of air communication holes and rises above the filter media layer. And the suspended solids attached to the filter sand of the filter medium layer is dropped by the micro vibration of bubbles rising upwards. Then, when the backwash water is supplied, the turbidity separated from the filtered sand is introduced into the backwash water collection tank together with the backwash water, and the discharge valve And wastewater discharge to the next recovery line.

In such a filter paper, the filtration block installed in the upper part of the base beam of the filtration tank should be kept horizontally uniform throughout, and the gap between each filtration block should be completely blocked, and thus the filtration block maintains the horizontality and airtightness. When backwashing, the water and air supplied through the lower collecting chamber are raised evenly over the front of the filtration tank so that the backwashing is uniformly performed.

However, in the conventional filter paper, a plurality of square filtration blocks are vertically and horizontally arranged on a plurality of support beams installed at regular intervals on the bottom of the wall, so that even when a skilled worker constructs the horizontal lines of each filtration block, It is very difficult to maintain, and after arranging a plurality of filtration blocks, mortar filling is performed between the filtration blocks. Therefore, even when a skilled worker constructs them, it is very difficult to completely remove the gap between the filtration blocks. There was this.

Therefore, conventionally, after installing the filtration block, the horizontality of the front surface is not maintained accurately, and the gap is partially formed, so that the air blown out through the lower collection chamber does not rise evenly, but is partially concentrated. As a result, the filter material layer stacked below the filtration area is lost due to the strong upstream of the partially concentrated air, and the filtration structure is broken, thereby losing the filtration capacity.

In addition, the lower collecting device of the filter paper should be able to clean all sludges in the lower collecting device during backwashing to raise the washing water in order to wash the filter medium, but in the conventional catchment area (에 水 領域) formed in the collecting block There was a problem that can not achieve the intended purpose.

That is, the conventional water collecting block for filter paper has a region that cannot be washed while the backwash water is ejected from the strainer fixing tube, which is called a catchment region, and this catchment region causes a problem in supplying clear water. As backwash water spewed out from the water did not work in the shooter area, sludge accumulated in the filter medium of the shooter area for a long time, and thus decayed the quality of the purified water, there was a problem such as affecting the odor.

The present invention was devised to solve the conventional problems and defects as described above, after placing a forming plate coupled to a plurality of strainer fixing tube on the support portion installed in the filtration tank, and after casting and curing the concrete slab thereon, A plurality of catcher blocks combined with a plurality of strainer fixing pipes and a catcher protrusion for preventing a bad influence by the shooter are installed on the concrete slab vertically and horizontally and fixed by mortar filling, and the concrete slab and the catchment block are fixed to each other. By installing the lower collecting layer by connecting the strainer to the communicating strainer fixing tube, it is possible to solve the horizontal problem of the filtration block, the mortar detachment problem and the installation problem of the anchor according to the conventional lower collecting device, and also prevent the adverse effect of the shooter. In order to provide a composite integrated lower collecting device Never.

In order to achieve the above object, the integrated integrated lower collecting device according to the present invention is a lower collecting device of filter paper, wherein a forming plate having a plurality of strainer fixing tubes is disposed on the supporting part formed in the interior of the filtering tank in a vertical and horizontal direction.

The integrated lower collecting device of Patent No. 454276, previously registered by the applicant of the present application, has a disadvantage of a structure that cannot prevent the breakthrough product or the catching area to compensate for the disadvantage caused by installing dozens or hundreds of blocks in the filter paper. The catchment block preventing water catchment block of Utility Model No. 268533 is a catchment block having a structure to prevent the catchment area, but it has the disadvantage of installing dozens or hundreds of blocks in one filter paper, but it is a complex integrated type according to the present invention.
