Abstract
The invention discloses a double-sleeve connecting elbow for turbulence conveyance and belongs to the field of material conveyance. The connecting elbow comprises a conveyance bent pipe formed by connection of two conveyance straight pipes with the same structure, wherein each conveyance straight pipe comprises an inner bypass pipe fixed to the top of the inner wall of a main conveyance pipe, the conveyance bent pipe comprises an inner bypass bent pipe fixed to the inner wall of a main conveyance bent pipe, multiple openings are evenly formed in the bottom of the inner bypass bent pipe in the axial direction, a drainage pore plate is arranged inside the inner bypass bent pipe and located above the openings, and the inner bypass bent pipe is communicated with the inner bypass pipe. Due to the fact that the inner bypass bent pipe is installed in a bent pipe at the conveyance shifting position, the inner bypass pipes in the conveyance straight pipes and the inner bypass bent pipe in the conveyance bent pipe are communicated, and in this way, blockage is prevented at the bent position during conveyance, abrasion of pipelines is reduced, and the service life of pipelines is prolonged. The double-sleeve connecting elbow can be applied to long-distance pneumatic conveyance of materials such as power plant fly ash, cement, limestone flour, aluminum powder, land plaster and coal powder.
Description
Technical field
The present invention relates to a kind of material-transporting system, particularly a kind of air-transport system.
Background technique
Geldart-D particle material device is primarily of transfer pump and conveyance conduit two large divisions composition, in a very long time in past, the device majority of Geldart-D particle material adopts single pipe transport, in course of conveying, melting concn is high, with regard to easy blocking pipe, melting concn is low, and air consumption increases, wind speed is too fast, pipe wear is serious, wastes energy, and increases amount of maintenance.By installing inner bypass pipe on main feedline inwall in prior art, secondary air can be produced in conveyance conduit and enough perturb air-flow, the stagnation material be blocked in conveyance conduit is taken up by turbulent flow, continue to carry along Flow of Goods and Materials direction, thus avoid the blocking of pipeline, reduce air consumption, save the energy, reduce the wearing and tearing of pipeline, reduce the maintenance cost of pipeline, but its deficiency is, in pipe conveying procedure, the place that material can be turned through some, it is through that this just makes the design source of the gas of above-mentioned double-jacket tube ash conveying pipe not form an entirety, thus will the blocking of ash conveying pipe be caused.Transporting system power consumpiton increases.Part inner bypass pipe serious wear in fly ash carry, makes whole double-jacket tube conveying principle not play due effect, and this just makes whole double-jacket tube road be in semiparalysis state.
Summary of the invention
The object of this invention is to provide a kind of turbulent transportation double-jacket tube connecting bend, strengthen the air flow property in pipeline, avoid conveying turning to block, by the wearing and tearing in low pipeline, extend the working life of pipeline.
The object of the present invention is achieved like this: a kind of turbulent transportation double-jacket tube connecting bend, comprise the transporting elbow linked together by conveying straight tube identical for two structures, described conveying straight tube comprises the inner bypass pipe be fixed on main feedline inwall top, described transporting elbow comprises the internal bypass bend pipe be fixed on main transporting elbow inwall, the bottom of described internal bypass bend pipe axially evenly offers some openings, described internal bypass bend pipe inside is provided with drainage orifice plate, described drainage orifice plate is arranged on the top of opening, and described internal bypass bend pipe is connected with inner bypass pipe.
Compared with prior art, beneficial effect of the present invention is, the present invention makes to carry the inner bypass pipe in straight tube and the internal bypass bend pipe in transporting elbow to be connected together by installing internal bypass bend pipe in the bend pipe of conveying conversion place, thus avoid blocking in bending part in course of conveying, thus reduce the wearing and tearing of pipeline, extend the working life of pipeline.The present invention can be used for the long distance pneumatic conveying of the materials such as flying ash in electric power plant, cement, agstone, aluminium powder, gesso, coal dust.
In order to strengthen the air circulation in conveyance conduit, avoid further blocking, near being provided with gassing pipe with transporting elbow joint on described two conveying straight tubes, described gassing pipe runs through main feedline and inner bypass pipe is arranged, and described two gassing pipes are connected through external pneumatic tube.When after pipe wearing and tearing other in elbow, external gassing pipe can be opened, ensure that the air-flow of the interior other pipe of whole double-jacket tube is unimpeded.Thus ensure that straight tube is unaffected.
In order to strengthen Wear-resistant corrosion-resistant of the present invention, the outside of described main feedline is arranged with compound lining stoneware pipe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein, 1 compound lining stoneware pipe, 2 main feedlines, 3 inner bypass pipes, 4 main transporting elbows, 5 internal bypass bend pipes, 6 drainage orifice plates, 7a, 7b gassing pipe, 8 external pneumatic tubes.
Embodiment
A kind of turbulent transportation double-jacket tube connecting bend as shown in Figure 1, comprise the transporting elbow linked together by conveying straight tube identical for two structures, conveying straight tube comprises the inner bypass pipe 3 be fixed on main feedline 2 inwall top, transporting elbow comprises the internal bypass bend pipe 5 be fixed on main transporting elbow 4 inwall, the bottom of internal bypass bend pipe 5 axially evenly offers some openings, internal bypass bend pipe 5 inside is provided with drainage orifice plate 6, drainage orifice plate 6 is arranged on the top of opening, internal bypass bend pipe 5 is connected with inner bypass pipe 3, near being provided with gassing pipe 7a with transporting elbow joint on two conveying straight tubes, 7b, gassing pipe 7a, 7b runs through main feedline 2 and inner bypass pipe 3 is arranged, two gassing pipe 7a, 7b is connected through external pneumatic tube 8, the outside of main feedline 2 is arranged with compound lining stoneware pipe 1.
The present invention is not limited to above-described embodiment; on the basis of technological scheme disclosed by the invention; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some to some technical characteristicss wherein to replace and distortion, these are replaced and are out of shape all in protection scope of the present invention.
