Abstract
The utility model relates to a buffer device of a powder material pneumatic conveying system, which belongs to the technical field of pneumatic conveying equipment, is used for solving the buffer problem of impact force when a container running quickly in a pipeline arrives, and comprises a spring, a gasket, an elastic cylinder, an outer sleeve and a lower flange, wherein the gasket is arranged at the upper part of the spring, and the gasket and the spring are arranged inside the elastic cylinder together; and the outer sleeve is arranged outside the elastic cylinder and fixed on the lower flange. Since the spring is arranged in the elastic cylinder, the metal gasket is additionally arranged in order to increase the contact area to prevent the spring from damaging the elastic cylinder, thereby protecting the elastic cylinder; and the outer sleeve is used for fixing and preventing the spring or the elastic cylinder from generating dislocation when rebounding. The utility model has reasonable structural design, reliable running, low cost, good buffer effect, low failure rate and convenient replacement.
Description
Technical field
A kind of granular material air-transport system shock absorber that is used for belongs to the pneumatic transport equipment technical field.
Technical background
Along with the maximization of cement equipment and improving constantly of unit-hour output,, sampling sample conveying device automatically need be installed in the production scene for satisfying production quality control requirement in the grinding process process.Take out the granular material cylindrical container of packing into then continuously by sample collector, deliver to the laboratory by pipe special by pneumatic conveying mode, all processes is by PC controller automatic guidance.Owing to be used to transmit speed that the container of material sample moves in closed conduit very soon usually more than 20m/s, its impulsive force in a flash when container arrives the laboratory or gets back to the scene is very big, strong vibrations very easily damage container, also can influence the normal operation of control element, also can influence normal quality control work.At present, the air-transport system that has adopts thick rubber pad to do buffering, and effect is undesirable; The installation air damping device in system that also has though buffering effect increases, need install four non-return valves additional and realize air damping, and making system equipment be tending towards complexity has like this increased installation difficulty, and serviceability is also bad.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art and shock absorber that a kind of reasonable in design, reliable, good buffer effect are provided.
Problem described in the utility model realizes with following technical proposals:
A kind of granular material air-transport system shock absorber is made of spring, pad, elasticity tube, overcoat, lower flange, and pad is placed in the elasticity tube inside of packing into together, spring top, and overcoat is installed in the rubber tube outside, is fixed on the lower flange.
Above-mentioned granular material air-transport system shock absorber, described elasticity tube profile is circular platform type, and inside is circular, barrel thickness 5-8mm, bottom platform thickness 10-12mm.
Above-mentioned granular material air-transport system shock absorber, the material of described elasticity tube is high-elastic rubber or polyurethane.
Above-mentioned granular material air-transport system shock absorber is distributed with 3-6 screw on the described overcoat flange.
In the granular material air-transport system working process, when sampling receptacle arrives, at first touch the elasticity tube, spring is compressed to the elasticity tube bottom and touches and issue orchid then and since spring at first be compressed reduced the impulsive force of sampling receptacle to the elasticity tube after, the elasticity tube buffer action that recurs, so the buffering effect of this shock absorber is remarkable, the utility model reasonable in design, reliable, cost is low, good buffer effect, fault rate is low, and it is convenient to change.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the bonded assembly scheme drawing of the utility model on sample collector;
Fig. 2 is a structural representation of the present utility model;
Each label is among the figure: 1, spring; 2, metallic gasket; 3, elasticity tube; 4, overcoat; 5, screw; 6, lower flange; 7, binding bolt; 8, plenum chamber; 9, plenum chamber base; 10, sampling receptacle; 11, container cover; 12, delivery duct; 13, blower fan communication port.
The specific embodiment
Consult Fig. 1, Fig. 2,
A kind of granular material air-transport system shock absorber, constitute by spring, pad, elasticity tube, overcoat, lower flange, elasticity tube profile is circular platform type, internal diameter is Φ 38 * 90mm, barrel thickness 5mm, bottom platform thickness 10mm, the material of elasticity tube is high-elastic rubber, spring diameter is Φ 36mm, and the overcoat flange has 4 screws and lower flange to be fastenedly connected.
Elasticity tube pad is placed in the elasticity tube inside of packing into together, spring top, overcoat is installed in elasticity tube outside, the overcoat flange is fastenedly connected by bolt and lower flange, shock absorber is outside to be fastenedly connected with lower flange the plenum chamber base being installed in, because the internal diameter of plenum chamber base is bigger than the external diameter of shock absorber, has formed granular material air-transport system plenum chamber, sampling receptacle is placed in elasticity tube top, build container cover, the delivery duct of packing into.
Overcoat adopts metallic material also can be used as support unit, and spring or elasticity tube misplace when being used to prevent to rebound.
The utility model reasonable in design, good buffer effect, fault rate is low, and it is convenient to change.
