The filter suspension positioning device

Technical field:

The utility model relates to a kind of suspension positioning device that is used for the dust separation device middle filtrator, belongs to dust separation device and makes the field.

Background technology:

All patent No.s of the applicant are 200320123935.6, title " filtering cylinder type dust-removing purification device-specific filter cylinder syndeton ", one flute profile bend pipe (2) is arranged in the upper port of the filter cylinder of this filter cylinder syndeton (1), the two ends of flute profile bend pipe are fixed on the orifice plate (1), suspension bracket (4) is fixed on the middle part of flute profile bend pipe, one end of back-moving spring (5) is connected with suspension bracket (4), the other end is connected with pull bar (6) one ends, base plate (8) is fixed in the other end of pull bar (6) and by cushion pad (7) lower port of base plate (8) with filter cylinder (1) is tightly connected, and the upper port of filter cylinder (1) seals flexible the connection by expansion pad (9) with the upper port of filter cylinder and the aperture formation all around of orifice plate (1).Blemish in an otherwise perfect thing be: the one, complex structure, manufacturing cost height; The 2nd, effectiveness in vibration suppression is not good, and noise is big, influences working environment; The 3rd, filter cylinder is contact with syndeton and is connected, and easily produces, and influences result of use.

Summary of the invention:

Purpose of design: avoid the weak point in the background technology, design and a kind ofly not only have simple in structure, low cost of manufacture, and have vibration damping, noise reduction, stable and reliable for performance and filter suspension positioning device that dynamic suspension that result of use is good connects.

Design: in order to realize above-mentioned purpose of design.The three-jaw of suspension or the pawl in the four paws are designed to spring and connect pawl, elastic claw reaches upward by spring housing, spring guide pillar, and lower spring constitutes, the design of the middle part annular boss in its spring housing, it is principal character of the present utility model, the purpose of the design of three-jaw or four paws spring housing is: three-jaw is suitable for the monotubular filter, and four paws is suitable for many filters.No matter be three-jaw, or four paws, hole in the middle of the middle part annular boss in its spring housing is that ammunition feed spring guide pillar passes spring housing, the annular boss at middle part is that spring housing is divided in the spring housing, following two mutual incoherent spring housings, and will go up respectively, lower spring places in the spring housing, on, one end of lower spring respectively with spring housing in annular boss touch mutually, on, the other end of lower spring adopts nut spacing and can adjust the elasticity of its spring by nut, purpose makes filter mounting and (in the cleaner) filter or filter installing plate form both separate, on cooperatively interacting again, following dynamic suspension syndeton, this structure is vibration damping effectively, reduce noise, and can make filter in vibration, try to achieve dynamic equilibrium, simultaneously by adjust lower spring or on, the elasticity of lower spring, can eliminate the unsettled defective of service behaviour that filter or filter installing plate tilt and to be brought easily and effectively, guarantee its well service behaviour and result of use reliably.

Technical scheme: filter suspension positioning device, suspension is the three-jaw structure, pawl in the three-jaw is spring housing (6) and annular boss (7) is arranged at the middle part of spring condom, spring guide pillar (1) passes spring housing (6), its upper and lower part is with upper spring (5) and lower spring (8) respectively, spring guide pillar (1) end in the upper spring (5) adopts nut (2) to limit upper spring (5), and spring guide pillar (1) end in the lower spring (8) adopts nut (2) to limit lower spring (8).Its suspension method of adjustment: there is annular boss at the middle part in the cover of the spring housing in the suspension, spring guide pillar passes the spring housing in the support respectively, on its spring guide pillar, the bottom is with upper spring and lower spring respectively, spring guide pillar in the upper spring passes the filter installing plate respectively and connects with the filter installing plate, spring guide pillar end in the lower spring adopts nut to limit the elasticity of lower spring, the center of filter installing plate is connected with the center of support by coupling bar, filter is connected with the filter installing plate, when the filter run-off the straight, the elasticity that only needs to adjust the elasticity of the lower spring of support medi-spring cover in trapping or adjust the last lower spring in the support medi-spring upper and lower sleeve gets final product.

The utility model is compared with background technology, the one, the design of three-jaw or four paws suspension positioning device, complex structure that the little structure of shaking of background technology middle filtrator exists, manufacturing cost height, effectiveness in vibration suppression is not good, noise is big defective have fundamentally been solved, avoided the inclination that produced in the filter mechanism vibration processes, guaranteed the reliable and stable of its service behaviour, and reduced noise significantly, built working environment well; The 2nd, spring guide pillar passes the spring housing (upper and lower spring housing) in the support respectively; the upper and lower part of its spring guide pillar is with the design of upper spring and lower spring respectively; not only fundamentally solve the noise increase that filter or filter installing plate tilt and vibration are caused; complete machine work shakiness, flimsy defective; and can conveniently adjust, make filter or filter plate to be in dynamic equilibrium state all the time; noise and energy consumption have greatly been reduced; protected environment; improve the efficient of udst separation, prolonged the service life of complete machine.
