Description

one

The invention relates to filtration, namely, to drainage filters, mainly designed for the treatment of surface water when they are introduced into the drainage system, and can be used for land reclamation.

A drainage filter is known, which includes a well, a water inlet connection with a filter element and a drainage drain 1.

The disadvantage of the filter is that in order to ensure the reception of a large amount of water inlet pipe with a filter element has a large size, and this increases the diameter of the well.

The purpose of the invention is to increase the filtering and culvert capacity of the drainage filter With a constant diameter of the intake and tubing.

This is achieved by the fact that the filtering element is designed as a tee with receiving and discharge nozzles equipped with filtering walls.

It is advisable to install the outlet nozzles of the filter element at an angle to the horizon, with the diametrically opposite points being located at the same level.

FIG. 1 shows the proposed filter, a general view; in fig. 2 shows section A-A in FIG. one.

The filter includes a well 1, a water supply ditch 2, a water inlet pipe 3 fixed in the wall of the well 1, a tee 4 installed by its side inlet

the end 5 on the end of the intake manifold 3 located inside the well 1, the coarse filtering grid 6, sandwiched between the side inlet end of the tee 4 and the inlet manifold 3 and blocking its outlet

the end, basic filters 7 and 8, respectively, fine and medium cleaning, with fixing rings 9, which can be irregular or internal fixation, overflow gap 10 above the filter in the middle cleaning, fixator

tee Y and diverting drain 12.

The filter works as follows. Water through the water supply ditch 2 flows to the well 1 and, as the levels increase, to the water inlet nozzle 3. At the exit from

the water inlet port 3 "passes through the coarse filtering net 6, is filtered and, cleaned of large inclusions, enters the inside of the tee 4. Since its body is angled to the horizon, water first flows to the thin filter 7 located cleaning, is filtered, enters the well 1 and then into the drainage drain 12. At the time of a considerable amount of water entering the drain filter, when the fine cleaning filter 7

fully loaded, the rest of the water is filtered through the medium filter 8, located at the top level, and in extreme cases, for example, when the fine filter clogged, and the water flow is very large, pours into well 1 through the overflow spout; filter 8 medium cleaning. The introduction of the filter will allow, with its unchanged dimensions, to increase the filtering and culvert capacity.
