Description
Technical Field
The utility model relates to an air filtering device at an air suction end of an air compressor, in particular to a filter cartridge connecting device of an air self-cleaning filter.
Background
The filtering mode of the air suction end of the air compressor is evolved from the earliest no-filtering mode to a cloth bag filter and then to the filtering mode of the air self-cleaning paper filter cartridge, and the filtering mode becomes the mainstream filtering mode at present, and has the advantages of high filtering precision, relatively low cost and the like.
The air compressor equipment of the steel enterprise has wide application, and generally more than 20 large air filtering devices are arranged in large steel mills. In order to meet the production requirement, a large number of spare parts of the air self-cleaning filter cartridge are required to be purchased for maintenance and replacement. However, the length of the filter cartridge on the market has three specifications of 720 cm, 730 cm and 740 cm, the filter cartridges purchased in different batches at different time intervals often have a difference of 10 to 20 cm, the size of the filter cartridge connecting device at the air suction end of the air compressor is fixed, the thread length of the filter cartridge connecting device is generally only 5cm, and therefore when the filter cartridges with different lengths are installed, the matched screw caps cannot be screwed, and the filter cartridges cannot be installed.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: to overcome the disadvantages of the prior art, the present invention provides an air self-cleaning filter cartridge attachment apparatus that is adaptable for installation of filter cartridges of different sizes.
The technical scheme is as follows: the utility model relates to a filter cartridge connecting device of an air self-cleaning filter, which comprises a hanging rod and a hanging rod fixing part; the hanging rod comprises a rod body and three hooks arranged at the top of the rod body, a threaded section is arranged at the bottom of the rod body, a limiting nut matched and connected with the threaded section is configured, and the three hooks are arranged in a stepped manner around the central axis of the rod body; the hanging rod fixing part is arranged below the venturi tube of the air self-cleaning filter.
Wherein, three couple are at body of rod circumference interval 120 distribution. So as not to interfere with each other when the fixed portion of the hanging rod is hung.
The height interval of the three hooks is more than 10 cm. To meet the installation requirements of three different sizes of filter cartridges.
The outer diameter of the limiting nut is more than 100 mm. To ensure that the cartridge can be pulled at the bottom.
The height of the thread section is more than 5 cm.
The three hooks are respectively 725cm, 735cm and 745cm away from the bottom end of the screw.
Has the advantages that: compared with the prior art, the device has the peg of three couple through the setting, and three couple is cascaded arrangement around the peg to can adapt to the installation needs of straining a section of thick bamboo of different length specifications, realize quick installation, reduce the transformation cost for adapting to different batches of straining a section of thick bamboo.
Drawings
FIG. 1 is a schematic view of an air self-cleaning filter cartridge attachment apparatus in use;
FIG. 2 is a schematic view showing the construction of a hanger bar of the air self-cleaning filter cartridge attachment means;
fig. 3 is a schematic view of the filter cartridge mounted on a hanger bar.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
When in implementation, the T-shaped dead joint of the central connecting part of the original air self-cleaning paper filter cylinder of the large-scale centrifugal air compressor is cut off. A V-shaped hanging rod fixing part 2 is welded by phi 10mm round steel below an original air self-cleaning filter venturi, and the layout structure of the hanging rod fixing part 2 is shown in figure 1.
With reference to fig. 2 and 3, a hanging rod 1 is manufactured for three length specifications of 720 cm, 730 cm and 740 cm filter cartridges 10 currently on the market. The rod body 11 can be bent to form three hooks 12 made of the same material, and the hooks are distributed and welded in a stepped manner around the central axis of the rod body 11, so that the three hooks 12 are distributed at intervals of 120 degrees in the circumferential direction of the rod body 11, the step height interval is more than 10cm, and the three hooks 12 are respectively 725cm, 735cm and 745cm away from the bottom end of the hanging rod 11 so as to correspond to filter cylinders 10 with different specifications.
A threaded section 13 with the height of more than 5cm is formed in the lower portion of the rod body 11 and used for installing a limiting nut 14 and supporting the filter cartridge 10, and the outer diameter of the limiting nut 14 is more than 100mm according to the size of a hole in the lower portion of the filter cartridge 10.
Of course, the size of the hanging rod 1 can be redesigned according to other filter cylinders 10 with new specifications, so that the adaptability of the device is improved, the filter cylinders 10 with various specifications can be quickly installed, and the halt installation time of the air compressor in a steel mill is greatly shortened.
