Abstract
The utility model relates to a transportation device for powdery materials, which comprises a tee joint structure body in an inverse T shape. The vertical section of the body is a feeding pipe. One end of the horizontal pipe is an intake end embedding a gas nozzle which is longer than the distance between the end and the central line of the feeding pipe while the other end is a discharge section which first narrows slightly and then enlarges slightly. The neck of the discharge section is positioned on the half or so of the entire discharge section. The joint inner wall of the intake pipe of the body and the horizontal pipe of the body is jointed transitionally in an arc shape. Flange structures are connected with the end of the intake pipe and the pipe ends of both the intake section and the discharge section. The utility model has the advantages of simple structure, continuous and reliable operation and high transportation efficiency.
Description
Technical field
The utility model relates to a kind of powder conveying apparatus, relates to a kind of granular material malleation Pneumatic conveyer specifically.
Background technology
In the coal-burning power plant, industry such as cement mill and metallurgy, chemical industry, often need adopt malleation or negative pressure pneumatic conveying mode to carry out the conveying of certain distance product materials such as fly ash, cement, breeze, chemical industry pellet, and be extensive use of a kind of L type storehouse formula malleation Pneumatic conveyer.This device generally includes warehouse, inlet valve, bleeder valve, level-sensing device, pressure sensor and control system.Its principle of work is: the charging stage: feed pipe is opened, and material freely falls in the warehouse, and after material in the warehouse rose to predetermined material level, level-sensing device sent the full signal of material, and the inlet valve SELF CL is finished fill process.The fluidisation pressure period: air inlet valve this moment self-opening under control system control, pressurized air enters the warehouse bottom, passes fluid bed after the diffusion, and the warehouse internal gas pressure rises in the abundant fluidisation of material.Delivery phase: when the warehouse internal pressure reached certain value, pressure sensor sent signal, the bleeder valve self-opening, goods fluid on the fluid bed quickens, carry beginning, material reduces gradually in the storehouse in, in this process on the fluid bed moral material be in the conveying of fluidisation limit, limit all the time.Purge stages: mass transport finishes in the storehouse, and when pressure decay arrived the resistance of ducting, indicator lamp sent signal, and ventilation continuity certain hour is closed bleeder valve, opens inlet valve, finishes delivery cycle one time.Problems such as this device exists in actual applications that volume is big, structure and control are complicated, and control instrument fault rate height can not continuous working, and transport efficiency is relatively low.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, continuously-running, the powder conveying apparatus that transport efficiency is high.
For realizing the object of the invention, the utility model adopts following technical scheme.
Powder conveying apparatus of the present utility model has inverted T shape three-port structure warehouse 1, vertical section of warehouse is feed pipe 2, one end of horizontal body is an inlet end 4, inlet end 4 embedded gas jets 3, the length of nozzle 3 surpasses the line of centers of feed pipe 2, other end levelling pipe is a discharge end, the little expansion behind the discharging direction elder generation micro of discharging section 5 pipe diameters.
The minimum place 6 of the diameter of discharging section 5 is positioned at about 1/2nd of whole discharging section and locates, the discharging section that is warehouse is located from its diameter of material inlet place about 1/2nd of whole discharging section that is reduced to slowly, it is minimum that diameter reaches, diameter its enlarged-diameter of exit that is increased to slowly arrives the diameter that discharging section enters the mouth afterwards, the minimum diameter of discharging section is the 55%-70% that neck is about horizontal pipe diameter, and the reducing and enlarge all of whole discharging section diameter seamlessly transits; One air chamber 7 preferably is set before the nozzle 3, air chamber 7 is that cylinder and cone constitute along air flow line, and air chamber has stabilizing gas pressure, buffering air pressure fluctuation and accumulation of energy effect, but sets air chamber assurance device stable operation, for the stable system of source of the gas, also can not establish air chamber; Warehouse feed pipe 2 is connected with circular arc 8 transition with the levelling pipe inwall, if connect with the right angle, then the material carrying capacity is relatively poor, and resistance is big, so be designed to arc transition; Gas jet 3 is a pipe, it is 1 that the pipe diameter gets the diameter ratio with the warehouse levelling pipe: 11-12, nozzle should not be thick excessively, should keep becoming a ratio with the warehouse caliber, in order to avoid cause air-loss excessive, proper proportion can improve jet expansion flow velocity and the circle round degree of gas in bin, improves the traffic capacity of material.Pipe end at the feed pipe 2 of warehouse, inlet end 4, discharging section 5 connects a flange arrangement, is called inlet point, admission port, discharging opening.
The utlity model has simple in structure, can be continuously, the failure-free operation, the transport efficiency advantages of higher.
Followingly in conjunction with the accompanying drawings the specific embodiment of the present utility model is described in further detail.

Embodiment
Among the figure, 1-warehouse, 2-feed pipe, 3-gas jet, 4-inlet end 5-discharging section, 6-discharge nozzle neck, 7-air chamber, 8-transition arc, 9-air inlet pipe
The powder material discharging opening is connected by valve is blue with the feedway inlet point, granular material freely falls into warehouse from warehouse feed pipe 2, the dry air of being sent here by air compressor is sent into the air inlet pipe (pipeline with admission port between be connected by valve is blue) of warehouse through pipeline, barotropic gas sprays from nozzle, below feed pipe 2, circle round to the warehouse discharge nozzle neck 6 formed bins and with after granular material mixes, collect and carry material and blow out from the warehouse discharging opening, along pipeline material is delivered to material library or other desired locations, the utility model can use with series connection separately according to fed distance.
