Abstract
The invention provides a filter, which comprises a barrel and a filter screen, wherein the filter screen is arranged in the barrel; the filter screen is conical and forms an included angle of 10 to 15 degrees with the horizontal plane; and the small end of the filter screen is welded with a cover plate, while the big end is welded with a filter barrel flange welded with two positioning pieces. The filter has the advantages that: the structure is simple; the filtering area is large; the flow resistance loss is small; and the impurities are prevented from being absorbed onto the filter screen and fall off easily when the filter screen is back washed.
Description
Affiliated technical field
The present invention relates to a kind of device, especially a kind of filter with the taper filter cylinder.
Background technology
Use the filter in water treatment systems such as metallurgy, municipal administrations at present, generally adopt cylinder type filter net, filter area is little, and flow resistance is big, and easily long-pending impurity on the filter screen, cleans inconvenience.
Summary of the invention
In order to overcome existing cylinder type filter net, filter area is little, and flow resistance is big, and easily long-pending impurity on the filter screen, cleans the deficiency of inconvenience, the invention provides a kind of filter.
The technical solution adopted for the present invention to solve the technical problems is a kind of filter, comprise cylindrical shell, filter screen, filter screen is contained in the cylindrical shell, filter screen is taper, the angle of itself and horizontal plane is 10 to 15 degree, the small end place of filter screen is welded with cover plate, and the big end place of filter screen is welded with the filter cylinder flange, also is welded with two spacers on the filter cylinder flange.
The invention has the beneficial effects as follows simple in structurely, filter area is big, and flow resistance loss is little, and impurity is difficult for being adsorbed with on the filter screen, and impurity comes off easily during recoil.
Description of drawings
Fig. 1 is the sectional structural map of embodiment
Among the figure: 1. spacer; 2. filter cylinder flange; 3. cylindrical shell; 4. filter screen; 5. cover plate.
The specific embodiment
As shown in Figure 1, 2, a kind of filter comprises cylindrical shell 3, filter screen 4, filter screen 4 is contained in the cylindrical shell 3, and filter screen 4 is taper, and its angle with horizontal plane is 10 to 15 to spend, the small end place of filter screen 4 is welded with cover plate 5, and the big end place of filter screen 4 is welded with filter cylinder flange 2, also is welded with two spacers 1 on the filter cylinder flange 2.Owing to adopt conical screen 4, increased filter area greatly, impurity is difficult for being adsorbed with on the filter screen, and impurity comes off easily during recoil.
