Abstract
The utility model discloses a quick connecting device for a spray-blowing pipe of a reverse-blowing filter and belongs to the technical field of reverse-blowing filters. The quick connecting device for the spray-blowing pipe of the reverse-blowing filter is characterized in that an air inlet pipe and the spray-blowing pipe are connected through a quick connecting mechanism, the quick connecting mechanism comprises a round sleeve fixedly arranged at the tail end of the air inlet pipe, the fixed end of the round sleeve is arranged at the tail end of the air inlet pipe in a sleeved mode and is welded to the air inlet pipe, the inner wall of a cylinder body of the movable end of the round sleeve is provided with at least two round grooves, O-shaped seal rings are fixed into the round grooves, and the spray-blowing pipe is inserted in the movable end of the round sleeve and is sealed through the O-shaped seal rings. The quick connecting device for the spray-blowing pipe of the reverse-blowing filter is reliable and stable in structure, lowers production cost, shortens the production period, effectively avoids the phenomenon that a gasket and a nut disengage in the installing process, is convenient and fast to install and maintain, and saves a large amount of labor force and working time.
Description
Technical field
The utility model belongs to power back-blowing filter technical field, is specifically related to a kind of power back-blowing filter spraying-blowing pipe quick connecting device.
Background technique
What in power back-blowing filter, between suction tude and injection tube, traditional Placement adopted is that flange is connected (as accompanying drawing 1) and be flexible coupling (as accompanying drawing 2), these two kinds of structures are all to adopt nut screwing clamping and gasket seal, in installation and maintenance process, nut and pad very easily fall into downstream, pollute to downstream product.Adopt traditional flange to connect, processing cost is higher, and the cycle is longer, and adopts traditional being flexible coupling, complex structure, installation process is more loaded down with trivial details, and these two kinds of Placements all to need fastening nut to carry out fastening, waste time and energy, for above problem, make improvements.
Summary of the invention
The utility model provides a kind of power back-blowing filter spraying-blowing pipe quick connecting device of rapid and convenient being installed and being convenient to injection tube installation and regulating for overcoming the deficiencies in the prior art.
The technical solution of the utility model is: a kind of power back-blowing filter spraying-blowing pipe quick connecting device, it is characterized in that: between suction tude and injection tube, connect by quick-connect machanism, this quick-connect machanism comprises the circular sleeve that is fixedly installed on suction tude end, the fixed end cap of circular sleeve is located at suction tude end and is welded together with suction tude, the cylinder inboard wall of circular sleeve movable end is provided with at least two circular grooves, in this circular groove, be fixed with O RunddichtringO, described injection tube is plugged in the movable end of circular sleeve and seals by O RunddichtringO.
The utility model compared with prior art has following beneficial effect: (1) reliable in structure is stable, has reduced cost of production, has shortened the manufacture cycle; (2) effectively avoided the obscission of installation process Intermediate gasket and nut; (3) installation and easy to maintenance quick, has saved a large amount of labour forces and man-hour.
Brief description of the drawings
Fig. 1 is the structural representation that conventional flange connects, and Fig. 2 is the structural representation that conventional softer connects, and Fig. 3 is structural representation of the present utility model, and Fig. 4 is use phase diagram of the present utility model.
Drawing explanation: 1, suction tude, 2, injection tube, 3, quick-connect machanism, 4, circular sleeve, 5, O RunddichtringO.
Embodiment
Describe by reference to the accompanying drawings embodiment in detail.A kind of power back-blowing filter spraying-blowing pipe quick connecting device, between suction tude 1 and injection tube 2, connect by quick-connect machanism 3, this quick-connect machanism 3 comprises the circular sleeve 4 that is fixedly installed on suction tude 1 end, the fixed end cap of circular sleeve 4 is located at suction tude 1 end and is welded together with suction tude 1, the cylinder inboard wall of circular sleeve 4 movable ends is provided with at least two circular grooves, in this circular groove, be fixed with O RunddichtringO 5, described injection tube 2 is plugged in the movable end of circular sleeve 4 and seals by O RunddichtringO 5.In installation process, first O RunddichtringO 5 is placed in the circular groove on circular sleeve 4 movable end madial walls, the movable end that then directly injection tube 2 is plugged in to circular sleeve 4 completes the connection procedure of injection tube 2 and suction tude 1.
More than show and described basic principle of the present utility model; major character and advantage; do not departing under the prerequisite of the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall into claimed scope of the present utility model.
