Abstract
The utility model discloses a quick joint of an air filter element, which comprises a female joint sleeve and a male joint sleeve, wherein a seal rubber ring is arranged between the female joint sleeve and an air inlet bottom plate of the quick joint; the female joint sleeve is fixedly connected with the air inlet bottom plate by a female sleeve connecting bolt; a seal flat gasket is arranged between the female joint sleeve and the male joint sleeve; and a filter element and a sleeve filter connecting rod are mounted at the lower part of the male joint sleeve. When the quick joint is used, the air inlet bottom plate and the seal rubber ring are tightly connected and fastened and are not required to be dismounted integrally when the filter element is replaced, the fixity and the sealing property are good, the filter element is connected with the female joint sleeve by the seal flat gasket, and the contact area of the gasket is large, so that stress is uniformly. According to the quick joint, disassembly and assembly of a filter cylinder are more time-saving and labor-saving compared with the original simple screw rod connection, the time for disassembling and assembling the filter cylinder requires 10-15 min originally, but only 0.5-1 min is required after the quick joint is adopted, the abundant time efficiency is won for a use unit, a host machine is protected more effectively, and the service life of the host machine is prolonged.
Description
Technical field
The utility model relates to a kind of air filtering core accessory, particularly uses in a kind of air filtering core snap joint.
Background technology
The unit air filtering core that uses at present only connects and connects by the M12X950 screw rod, air intake has vibrations during use, and the screw rod stress surface is little, only on a point, use looseningly easily for a long time, loosening increasing base plate and the filter cylinder gap of causing is large in the course of time, thereby directly enter air, do not play airfiltering effect, air directly enters main frame and causes harm to main frame, has shortened the service life of main frame.
The utility model content
The purpose of this utility model provides a kind of good seal performance, can not occur the air filtering core snap joint of loosening phenomenon when main frame air intake and blowback.
The technical solution of the utility model is: a kind of air filtering core snap joint, comprise joint mother set, the public cover of joint, be provided with O-ring seal between its joint mother set and the air inlet base plate and be fixedly connected with by the mother set connecting bolt, be provided with the sealing plain cushion between the public cover of described joint mother set and joint, filter core and cover filter connecting rod are installed in the public cover of joint bottom.
When this joint used, air inlet base plate and O-ring seal are tightly connected did not more need integral demounting during renew cartridge after fastening, stationarity and good seal performance, and filter core is connected with the joint mother set to adopt and seals plain cushion, and it is large, stressed even that this fills up contact area.
The relatively original simple screw rod connection disassembling assembling of the utility model filter cylinder was time saving and energy saving, originally dismantled and turned and join a cover filter cylinder and take about 10-15 minute, only took 0.5-1 minute after the employing snap joint.The former replacing during with screw device carried out after filter cylinder need be shut down, and can change in not shutdown situation after adopting snap joint, wins the service life that a large amount of time benefits and more effective protected host have prolonged main frame through applying unit.
This air filtering core be applicable to the industries such as smelter, mine, gas manufacturing large air compressor, take out flow fan, generating set etc.
