Description
Technical field
The utility model relates to pneumatic transport equipment field, especially, relates to a kind of valve formula for Pneumatic conveyer and closes wind discharger.
Background technology
To large circulation goods such as grain, cement in bulk, load in bulk, loose unloading, can save a large amount of Packaging Resources, work and traffic cost.Negative-pressure pneumatic is carried in above-mentioned " three is loose " transport has important technology status, and so-called negative-pressure pneumatic is carried and referred to material, is entered subatmospheric pipeline by " suction ", completes the process of conveying.This process completes in a sealing, containing circulation, and suction tube is simply light, can " all-pervasive ", and dirt powder is had no way of and being flown upward, and clean storehouse is without point big and small.
The large harbour pneumatic ship unloader to hundred tons of materials of suction destiny per hour, the little indoor grain elevator to more than ten tons of suction fortune per hour, these negative-pressure pneumatic transmission systems, none does not use the so a kind of device of so-called air sealer; It should draw off material negative-pressure pneumatic delivery system, closes and pins atmosphere or more anticyclonic air again, makes to flow in a large number negative pressure cavity volume, to maintain negative-pressure pneumatic feed status.Air sealer, what have is again lock wind apparatus, closes wind discharger.
What current this class negative-pressure pneumatic transmission system was in the world used is all impeller swinging air sealer, and this air sealer is made up of the driver train of shell, impeller and impeller; The accurate inner cylinder of shell has inlet point and discharging opening; Impeller generally has 5～9 thick top blades, two leaf dishes and wheel shaft, wheel hub, Ye Ding and leaf dish outer rim are processed through precision cutting, can with the accurate shell inner cylinder except feed inlet and outlet, move and fit in the kinematic pair that air-flow can not pass through in a large number, inlet point is communicated with system negative pressure cavity, when operation, material constantly enters the space between any two blades, and the blade that is constantly sheared again the rotation that enters shell fitting surface takes discharging opening to and discharges.
This air sealer moulding and control are simple, space occupy-place is little, but its mode of operation has determined following critical defect;
-. cause the energy utilization rate of system low
In the conveying of high negative pressure strength, 1 kg of air per kg of water evaporated often will complete the conveying task of 20 kilograms of left and right materials, therefore, the air quantity of system is few and precious, but system vacuum degree is high, the gas leakage speed gapping is up to a few tenths of M (Mach), and this air sealer must retain a certain tolerance clearance that impeller can be rotated smoothly, therefore at the beginning of design, just leave the gas leakage wind loss of 10% left and right, in addition, the rotary actuation power of air sealer has also accounted for 5% left and right of pneumatic power.
Two. strong wear brings the acceleration of system to lose efficacy
Wall, leaf Top and the material mode of operation contacting that uninterruptedly rubs, make the wearing and tearing of the impeller swinging air sealer that any hard wear-resistant material manufactures until lost efficacy very soon all inevitable, in high negative pressure system, in the gap that rapid wearing expands, air will be with a few tenths of M (Mach) speed seepage, when seepage increases by 10%, the output of system just declines approximately 30%, actual count; Inhale freight volume several kilotons at least, tens thousand of tons at most, output is just plummeted to below 70%, this present situation is still to adopt suction fortune system that roots blower inhales fortune inorganic particle for very, because the inorganic powder particle of high speed seepage air-flow Relying band, essence is the fitting surface of this air sealer to be continued to strong Chong Shua Subcommittee-to mill.The financial cost that the inefficacy of impeller swinging air sealer is changed has generally accounted for 30% of the system energy and consumption of materials price total amount.
Three. cause the card of system to stop fault rate high
Blade generally, with the frequency of 4～8 times per second, enters pass wind with feed hole edges shearing and coordinates, this mode of operation, the probability that makes its generation card stop fault is very large, statistics inhale fortune some containing the high material of strip impurity content, each work team can clip 1～2 time, each troubleshooting stops production 0.25～2 hour.
