Abstract
The utility model relates to a pneumatic conveying device for solid powder or granular materials, in particular to an adjustable feed injector. The injector which comprises a feed hopper, a nozzle and a mixing and diverging pipe is characterized in that one side of the lower end of the feed hopper is horizontally connected with an air inlet pipe guide tube in an extending manner; an air inlet pipe is arranged by passing through the air inlet pipe guide tube; one end of the air inlet pipe positioned in the feed hopper is connected with the nozzle; a locking piece used for fixing the air inlet pipe is arranged on the air inlet pipe guide tube; and the other side of the lower end of the feed hopper is horizontally connected with the mixing and diverging pipe in an extending manner. The injector mainly solves the technical problems of the traditional solid-gas injector that the ratio between the feed rate and the gas consumption (the mixing ratio of the solid and the gas) is low, the feed efficiency is low, the pressure drop of the injector is large, the energy consumption is high, and the like. When the gas conveying capacity and the gas conveying distance are different, the distance S between the outlet of the nozzle and the inlet of the throat part of the air inlet pipe guide tube is adjusted for finding out the maximum feed rate (namely the maximum mixing ratio of the solid and the gas) and improving the feed efficiency of the injector.
Description
Technical field
The utility model relates to solid powder, pellet Pneumatic conveyer, particularly a kind of adjustable feed injector.
Background technology
Gas delivery is under certain condition, utilizes gas a special kind of skill for carrier conveying solid substance particle, powder, is widely used in the conveying of industry powder material such as chemical industry, metallurgy, food, medicine.Flow delivery systems partly is made up of air supply system, loader, delivery duct and purpose feed bin etc. usually.Wherein loader mainly sends jar two kinds of feed forms of feed by rotary unloading valve feed and pressure,
The rotary unloading valve has more tangible advantages such as volume is little, setting height(from bottom) is low, operating sequence is simple, continuity is good.Its shortcoming is the part delivering gas to be arranged from this equipment leakage in the course of conveying, produces loss.
Pressure sends jar and is mainly used in the long especially situation of delivery pressure height, fed distance, but its shortcoming is that (1) floor area is big, device height is than higher; (2) realize to take two jars to carry when carrying continuously; (3) the valve member switch is frequent, the fault rate height.
Gas-solid formula eductor also can replace the rotary unloading valve, and as feeding Device of Pneumatic Conveying as shown in Figure 1: it mainly is made up of nozzle A, feed hopper B, the C of receiving chamber, mixing tube D, diffuser pipe E and delivery duct F.
The air of certain pressure and flow is by behind the injector nozzle A, with very high speed by the C of receiving chamber and enter among the mixing tube D, because nozzle A diameter is littler than caliber, the speed of bringing about the desired sensation is improved and the static pressure reduction, form certain negative pressure this moment in the C of receiving chamber, material injected air-flow immediately sucks, and together enters mixing tube D.Material and high velocity air further mix in mixing tube D and pass through diffuser pipe E supercharging, in this process, air is passed to material with a part of kinetic energy, material is quickened, to obtain certain delivery speed, air velocity further reduces simultaneously, and aerodynamic energy is converted into static energy, carries required pressure to satisfy.
But the shortcoming of above-mentioned existing gas-solid injector is that the material spray amount is low with the ratio (being the solid and gas mixture ratio) of gas consumption, and feed efficient is low, the eductor resistance drop is big, the energy consumption height.Prove through experimental study: for the gas-solid injector of a fixed structure, jet area and laryngeal entrance cross-sectional distance S measure decisive action to material spray.
The utility model content
The purpose of this utility model is to provide a kind of adjustable feed injector, the ratio (being the solid and gas mixture ratio) that mainly solves existing gas-solid injector material spray amount and gas consumption is low, feed efficient is low, the eductor resistance drop is big, energy consumption high-technology problem, under different conveying tolerance, fed distance, by regulating jet expansion interface and laryngeal entrance interface distance S, find maximum material material spray amount (promptly maximum solid mixture ratio), improve the feed efficient of eductor.
For achieving the above object, the utility model is achieved in that
A kind of adjustable feed injector, it comprises feed hopper, nozzle and mixing diffuser pipe; It is characterized in that: described feed hopper lower end one side horizontal-extending connects an air inlet pipe guide pipe, wear an air inlet pipe in this air inlet pipe guide pipe, the end that this air inlet pipe is positioned at feed hopper connects nozzle, is equipped with the locking part that is used for fixing air inlet pipe on the described air inlet guide pipe; Described feed hopper lower end level connects corresponding to air inlet pipe guide pipe opposite side and mixes diffuser pipe.
Described adjustable feed injector is characterized in that: described mixing diffuser pipe is sheathed in the freeing pipe guide pipe.
Described adjustable feed injector is characterized in that: described feed hopper is horizontal section area decrescence a shape from top to bottom.
Injector nozzle is exported the interface to the utility model and laryngeal entrance interface distance S is designed to adjustable structure, in different conveying tolerance, under the fed distance, by regulating this apart from S, find maximum material material spray amount, promptly maximum solid mixture ratio, the feed efficient of raising eductor.

The specific embodiment
See also Fig. 2,3, it is the structural representation of a kind of adjustable feed injector of the utility model.As shown in the figure: it comprises feed hopper 1, nozzle 6 and mixes diffuser pipe 4; Described feed hopper 1 lower end one side horizontal-extending connects an air inlet pipe guide pipe 2, wear an air inlet pipe 5 in this air inlet pipe guide pipe 2, the end that this air inlet pipe 5 is positioned at feed hopper 1 connects nozzle 6, is equipped with the locking part 7 that is used for fixing air inlet pipe 5 on the described air inlet guide pipe 2; Described feed hopper 1 lower end level connects corresponding to air inlet pipe guide pipe 2 opposite sides and mixes diffuser pipe 4.Described mixing diffuser pipe 4 is sheathed in the freeing pipe guide pipe 3.Described feed hopper 1 is horizontal section area decrescence a shape from top to bottom.
During use, by regulating nozzle 6 and mix between the diffuser pipe 4, under different suction quantity, different material, different fed distance (being that eductor exports back pressure) condition, can find an optimum distance S, make material spray amount maximum apart from S.
Adjustable feed injector of the present utility model can replace rotovalve as loader, is applied to fed distance and is not more than in the strength conveying engineering that 100 meters, operational throughput are not more than 6 tons/hour.
