Abstract

The utility model discloses a rotary filtering type filter, belonging to the field of separated filtering devices. The rotary filtering type filter is composed of a water inlet pipe, a water outlet pipe, a filtering cylinder, a desilting cylinder, an isolating cylinder, a conical framework, a cylindrical framework, and a filtering net, wherein, the isolating cylinder is arranged inside the filtering cylinder; the isolating cylinder is provided with a conical framework which is provided with a cylindrical framework, and the cylindrical framework is laid with the filtering net. The filtering net is arranged in a centrifugal type isolating cylinder. With small volume, low cost, small pressure loss of water end, strong self-purification ability, and favorable filtering effect, the utility model is suitable for drip irrigation system to use.

Description

Rotary filtering type filter

The utility model revolves the filter field that filter formula filter belongs to separation, and it is by water inlet pipe and water outlet pipe, cartridge filter, and the desilting tube is formed.

Drip irrigation system generally adopts net type filter, and is simple in structure, and the dirt that filters out accumulates on the filtering net surface easily, and the build-up of pressure loss is big.Centrifugal type filter, poor filtration effect, when particularly silt content was big in water, the drip irrigation zone was easily stopped up.

The purpose of this utility model be to avoid weak point of the prior art and provide a kind of centrifugal combine with filter net type be applicable to drip irrigation system revolve filter formula filter.

The purpose of this utility model reaches by following measure, and it is by water inlet pipe and water outlet pipe, cartridge filter, the desilting tube is formed, and the isolating cylinder that is connected with cartridge filter in cartridge filter is provided with a conical framework in isolating cylinder, be fixed on the isolating cylinder, on framework, lay filter screen.Isolating cylinder makes the bigger water of silt content that enters cartridge filter by water inlet pipe can not enter clear water zone, increased the rotary speed of current simultaneously, improve the ability of centrifugation, the current that a small amount of silt of gathering on the filtering net surface is rotated rinse out, and stronger self-purification ability is arranged.Lay filter screen on the framework in isolating cylinder, form a filter, make centrifugalled water, make centrifugally to combine with filter net type again through strainer filtering.

Filter area and enhancing filter effect in order to strengthen filter screen are provided with a cylindrical frame in the framework in isolating cylinder, be connected with conical frame, lay filter screen on framework.

In order to reduce the loss of head, outlet pipe is drawn along the tangential direction of filtering barrel.

The utility model is contained in filter screen in the centrifugal cylinder, and volume is little, and cost is low, and the head pressure loss is little, and stronger self-purification ability is arranged, and good filtration effect is a kind of filter that is applicable to that drip irrigation system uses.

Accompanying drawing 1 is depicted as structural representation of the present utility model.

Accompanying drawing 2 is the vertical view of accompanying drawing 1.

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1, it is by water inlet pipe (8), outlet pipe (1), cartridge filter (6), desilting tube (5), isolating cylinder (7), conical frame (2), cylindrical frame (3), filter screen (4) is formed, the isolating cylinder (7) that in cartridge filter (6), is connected with cartridge filter, it can be similar to the shape of cartridge filter (6), and a conical framework (2) is set in isolating cylinder (7), be fixed on the isolating cylinder (7), a cylindrical frame (3) is set in conical frame (2), is connected, on framework, lay filter screen (4) with conical frame (2).After water enters cartridge filter (6) by water inlet pipe (8), isolating cylinder (7) separates unfiltered water and clear water, a cylindrical frame (3) is set in conical frame (2), and on two frameworks, lay filter screen (4), form strainer filtering, centrifugalled water is again through strainer filtering, makes centrifugally to combine with filter net type.

As shown in Figure 2, outlet pipe (1) is drawn along the tangential direction of cartridge filter (6) wall, makes current from entering cartridge filter (6) to filtering back output clear water, and current all are horizontal directions, have reduced the loss of flood peak.

Claims

1, a kind of by water inlet pipe and water outlet pipe, cartridge filter, desilting tube are formed revolves filter formula filter, and the isolating cylinder that it is characterized in that in cartridge filter being connected with cartridge filter is provided with a conical framework in isolating cylinder, be fixed on the isolating cylinder, lays filter screen on framework.

2, the filter formula filter that revolves according to claim 1 is characterized in that a cylindrical frame is set in the framework in isolating cylinder, is connected with conical frame, lays filter screen on framework.

3, the filter formula filter that revolves according to claim 2 is characterized in that outlet pipe draws along the tangential direction of filtering barrel.
