Abstract
The utility model discloses a turbulence delivery double-sleeve combination in the field of material delivery systems. The turbulence delivery double-sleeve combination comprises an inner bypass pipe fixed onto the top of the inner wall of a main delivery pipe. A plurality of openings are axially and uniformly formed in the bottom of the inner bypass pipe, and a plurality of flow guide porous plates are arranged inside the inner bypass pipe and are arranged above the openings. The turbulence delivery double-sleeve combination has the advantages that the inner bypass pipe is mounted on the inner wall of the main delivery pipe, so that sufficient disturbance airflow can be generated in a delivery pipeline by auxiliary airflow, stagnant materials blocked in the delivery pipeline can be carried by turbulence and continue to be delivered along a material flowing direction, accordingly, blockage of the pipeline is prevented, gas consumption is reduced, energy is saved, abrasion of the pipeline is reduced, the pipeline maintenance cost is decreased, and the turbulence delivery double-sleeve combination can be used in the long-distance pneumatic delivery industry for materials such as fly ash of power plants, cement, limestone powder, aluminum powder, gypsum powder and pulverized coal.
Description
Technical field
The utility model relates to a kind of material-transporting system, particularly a kind of air-transport system.
Background technology
Strength convey materials device mainly is made up of transmission pump and delivery duct two large divisions, in a very long time in past, the most single tube feedways that adopt of the device of strength convey materials are in course of conveying, the melting concn height, just easy blocking pipe, melting concn is low, and air consumption increases, wind speed is too fast, pipe wear is serious, wastes energy, and increases maintenance capacity.
The utility model content
The purpose of this utility model provides a kind of turbulent handling double catheterization cannula, makes secondary air can produce enough moving air flows of scratching in delivery duct, and the stagnation material that is blocked in the delivery duct is taken up by turbulent flow, continues to carry along the Flow of Goods and Materials direction.
The purpose of this utility model is achieved in that a kind of turbulent handling double catheterization cannula, comprise the internal by-pas pipe that is fixed on the main feedline inwall top, the bottom of described internal by-pas pipe axially evenly offers some openings, described internal by-pas pipe inside is provided with some drainage orifice plates, and described drainage orifice plate is arranged on the top of opening.
During the utility model work, under the low speed feed status, growth along with the delivery duct distance, material Turbulence Flow state is destroyed, and accumulate in the main feedline bottom surface, main delivery pipe is tending towards plugging because material gathers, resistance increases, deposition material section is located to such an extent that pressure drop sharp increase makes the charge air that enters the internal by-pas pipe increase, after air entered the internal by-pas pipe, because the pressure reduction between the 2 gas flow jet points is greater than the material of the carrying point-to-point transmission pressure that breaks, the air of internal by-pas pipe flowed into main feedline again, again the air that flows into main feedline forms turbulent flow in this zone, and the disconnected heap of this material is dispelled.Gas ash compound flows into and flows out the internal by-pas pipe and constantly repeats in whole defeated grey process, this sample breaks and constantly cuts apart in main feedline, moves, dispels, material constantly is fed forward, thereby makes the turbulence double-pipe pneumatic ash conveying system realize the stable defeated ash operation of turbulent flow of low flow velocity, high concentration.Compared with prior art, the beneficial effects of the utility model are, the utility model makes secondary air can produce enough moving air flows of scratching in delivery duct by at the main feedline inwall internal by-pas pipe being installed, and the stagnation material that is blocked in the delivery duct is taken up by turbulent flow, continuation is carried along the Flow of Goods and Materials direction, thereby avoided the obstruction of pipeline, reduced air consumption, saved the energy, reduce the wearing and tearing of pipeline, reduce the maintenance cost of pipeline.The utility model can be used for the length of materials such as flying ash in electric power plant, cement, agstone, aluminium powder, gypsum powder, coal dust and carries industry apart from strength.
In order to strengthen the turbulent effect of this device, further strengthen the transport efficiency of material, described opening is fan-shaped opening, and internal by-pas inside pipe wall opening is less than opening of external wall, described fan-shaped opening is divided into opening admission port and opening air extractor duct by the drainage orifice plate, the tapering of described opening admission port is 45 °, and the tapering of described opening air extractor duct is 60 °.
In order to strengthen wear-resisting resistance to corrosion of the present utility model, the outside of described main feedline is arranged with the compound lining earthenware pipe.
In order to strengthen the utility model reliability of fixation, described compound lining earthenware pipe, main feedline and internal by-pas pipe are through bolt together.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 compound lining earthenware pipe, 2 main feedlines, 3 internal by-pas pipes, the fan-shaped opening of 3a, 4 drainage orifice plates.
The specific embodiment
A kind of turbulent handling double catheterization cannula as shown in Figure 1, comprise the internal by-pas pipe 3 that is fixed on the main feedline 2 inwall tops, the bottom of internal by-pas pipe 3 axially evenly offers some fan-shaped opening 3a, and wall opening is less than opening of external wall in the internal by-pas pipe 3, internal by-pas pipe 3 inside are provided with some drainage orifice plates 4, drainage orifice plate 4 is arranged on the top of fan-shaped opening 3a, fan-shaped opening 3a is divided into opening admission port and opening air extractor duct by drainage orifice plate 4, the tapering of opening admission port is 45 °, the tapering of opening air extractor duct is 60 °, the outside of main feedline 2 is arranged with compound lining earthenware pipe 1, compound lining earthenware pipe 1, main feedline 2 and internal by-pas pipe 3 are through bolt together.
During the utility model work, under the low speed feed status, growth along with the delivery duct distance, material Turbulence Flow state is destroyed, and accumulate in main feedline 2 bottom surfaces, main feedline 2 roads are tending towards plugging because material gathers, resistance increases, deposition material section is located to such an extent that pressure drop sharp increase makes the charge air that enters internal by-pas pipe 3 increase, after air enters internal by-pas pipe 3, because the pressure reduction between the 2 gas flow jet points is greater than the disconnected pressure of the material of carrying point-to-point transmission, the air of internal by-pas pipe 3 flows into main feedline 2 again, again the air that flows into main feedline 2 forms turbulent flow in this zone, the disconnected heap of this material is dispelled, and gas ash compound flows into and flows out internal by-pas pipe 3 and constantly repeats in whole defeated grey process, and this sample breaks and constantly cuts apart in main feedline 2, mobile, dispel, material constantly is fed forward, thereby makes the turbulence double-pipe pneumatic ash conveying system realize low flow velocity, the stable defeated ash operation of the turbulent flow of high concentration.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
