Taper slight drag water system filter
Technical field
The utility model relates to a kind of taper slight drag water system filter, specifically is used for the recirculated water water system filtration treatment of environment-friendly engineering or energy conservation project.
Background technology
At present, the recirculated water water system of environment-friendly engineering or energy conservation project need arrange filter, and the suspension in the recirculated water and granule foreign are carried out filtration treatment.Existing recirculated water water system filter is made of columnar housing and the round sheet filter screen that is fixed in the housing.During use, water to be filtered is flowed into by the water inlet of filter screen one side, and behind the filter screen of flowing through, the delivery port by the filter screen opposite side enters the required pipeline of user, and the granule foreign in the water is held back by filter screen.
Adopt said structure, the filter screen effective filtration area of round sheet is little, and the resistance to water-flow when making filtration treatment is big, and is low to the filtration treatment ability of recirculated water, and filter screen is blocked easily, and the filter screen clean and maintenance after stopping up is very inconvenient.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of taper slight drag water system filter, is used for reducing resistance to water-flow, increases water system filtration treatment ability.
The technical solution of the utility model is as follows: a kind of taper slight drag water system filter comprises housing (1) and is fixed on the interior filter screen (2) of housing (1) that it is conical that described housing (1) and filter screen (2) all are.
The utility model is by all being designed to taper shape with the filter screen in housing and the housing, under the identical situation of diameter, conical lateral area is far longer than the area of circular piece, thereby increased the effective filtration area of filter screen, resistance to water-flow when having reduced recirculated water water system filtration treatment has increased the filtration treatment ability of water system significantly.
On the sidewall of described housing (1), have two inspection openings relatively, be stamped lid (3) on the described inspection opening, inspection opening and lid are set like this, can conveniently check the operating position of filter screen, fix a breakdown when being convenient to overhaul of the equipments.
The larger diameter end of described housing (1) and ellipse head (4) welding are fixing, are connected with delivery port joint (5) on the described ellipse head (4); Described ellipse head is the standard component in the pipeline part, adopts this standard elliptical head not only good looking appearance, shape smoothness, can effectively reduce resistance to water-flow, and the intensity height, is conducive to improve the bulk strength of filter.Smaller diameter end at described housing (1) is welded with standard flange (6), and the smaller diameter end of being convenient to filter connects inlet channel.
In order to improve the service life of filter screen, described filter screen (2) is by 1-5mm thick carbon steel or stainless steel materials punch forming.
Beneficial effect: the utility model is by all being designed to taper shape with the filter screen in housing and the housing, under the identical situation of diameter, conical lateral area is far longer than the area of circular piece, thereby increased the effective filtration area of filter screen, resistance to water-flow when having reduced filtration treatment, increased the filtration treatment ability of water system significantly, have be skillfully constructed, simple in structure, produce easily and characteristics such as production cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As depicted in figs. 1 and 2, the utility model comprises housing 1, filter screen 2, lid 3, ellipse head 4, delivery port joint 5 and standard flange 6, it is conical that its middle shell 1 is, be welded with filter screen 2 in the described housing 1, it is conical that described filter screen 2 also is, and this filter screen 2 is by 1-5mm thick carbon steel or stainless steel materials punch forming.Have two inspection openings on the sidewall of described housing 1 relatively, all face down bondings of described inspection opening are connected to the edge, hole, are stamped lid 3 on the inspection opening, and described lid 3 links to each other along sealing with the hole, and inspection opening is sealed.
The larger diameter end of described housing 1 and ellipse head 4 welding are fixing, are connected with delivery port joint 5 on the described ellipse head 4.Described ellipse head 4 is the standard component in the pipeline part, and its shape and structure are same as the prior art, do not give unnecessary details at this.The number of described delivery port joint 5 is decided according to actual operating position, can be one or more; The shape of delivery port joint 5 is also decided according to actual operating position, can be straight peen, also can be 90 ° of elbows, and the preferred described delivery port joint 5 of present embodiment is 90 ° of elbows, and its quantity is two.Smaller diameter end at described housing 1 is welded with standard flange 6.
Although below by reference to the accompanying drawings preferred embodiment of the present utility model is described; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic rather than determinate; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite of the utility model aim and claim; can make multiple similar expression, all fall within the protection domain of the present utility model.
