Abstract
The utility model discloses a separator for pneumatic delivery of powder particles, and the separator comprises a delivery pipeline. An expanding section with the diameter larger than the diameter at the two ends of delivery pipeline is arranged inside the delivery pipeline. The separator has reasonable structure, and can effectively remove the heavy impurities mixed in the powder particles so as to improve the quality of powder particles.
Description
Technical field:
The utility model relates to the disconnector that a kind of powder strength is carried.
Background technology:
In the commercial production, sneak into the heavy seeds such as metal fragment that come off because of the production facilities fault in the powder product unavoidably, these impurity not only influence the quality of product, also can user's equipment be constituted a threat to sometimes.At present can tackle iron class foreign material, but also not have suitable hold-up interception method for the foreign material of materials such as corrosion-resistant steel, copper with the magnetic force method.
It is that the high-speed gas that dependence speed reaches about 25m/s disperses powder and granule shape material, be suspended in the air-flow and carry that strength is carried.Strength is carried and can be reduced two types of horizontal feed and vertical transport.Two types are had both at the same time in the actual process of pneumatic transmission.
In the wind-force course of conveying, powder with certain speed with gasmovement.When containing the bigger metallic foreign body of proportion in the powder, calculate by theoretical, these heavy foreign material can not be transferred under speed u, and in fact heavy foreign material can be transferred together.Major cause is these heavy foreign material not only are subjected to wind-force in the wind-force course of conveying effect, also is subjected to the impact effect of motion powder, thereby slowly displacement in delivery duct finally is transferred.Just find in the cellulose diacetate sheet is produced: the bolt that comes off on the production facilities, nut, fracture metal fragment etc. all can be delivered to bunker by wind-force together with the diacetate fiber flake products, thereby go out with product one lifting pin.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and can effectively remove the heavy foreign material of sneaking in the powder, improves the disconnector of the powder strength conveying of powder quality.
Technical solution of the present utility model is:
The disconnector that a kind of powder strength is carried is characterized in that: comprise delivery duct, the expander section that diameter enlarges than the two ends delivery pipe is set in delivery duct.
Expander section bottom is provided with the hole of taking out heavy foreign material.
The utility model structure is reasonable, can effectively remove the heavy foreign material of sneaking in the powder, improves the powder quality.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of embodiment 1.
Fig. 2 is the configuration diagram of embodiment 2.
The specific embodiment:
Embodiment 1:
The disconnector that a kind of powder strength is carried comprises the horizontal feed pipeline, and the expander section 3 that diameter enlarges than two ends delivery pipe 1,2 is set in the horizontal feed pipeline, and expander section bottom is provided with the hole 4 of taking out heavy foreign material.
The utility model proposes the local horizontal feed pipeline diameter that strengthens, the wind-force delivery speed is reduced, suddenly near " deposition velocity " of horizontal feed.Under deposition velocity, after the powder with certain initial velocity enters the expander section, under effect of inertia, move forward, less powder still can pass through the expander section, and the particle that a small amount of diameter is big is big because of suffered resistance, then begins in the bottom deposit of expander section tube wall.Bulky grain deposition causes flow section to reduce, and wind speed increases, reach new balance after, bulky grain finally also is transferred.Heavy foreign material are than great, and former wind-force delivery speed just is lower than its deposition velocity, is to be moved conveying under the impact effect of powder.At the expander section, wind speed reduces suddenly, and heavy foreign material are deposited on the expander section, and because of powder is under the deposition velocity, impulsive force is minimum, and heavy foreign material do not have the external force effect again, no longer are transferred with regard to being deposited on the expander section.Regularly open the hand hole of expander section, can from the powder that gathers, find separated heavy foreign material.
Embodiment 2:
The disconnector that a kind of powder strength is carried comprises the vertical transport pipeline, and the expander section 7 that diameter enlarges than two ends delivery pipe 5,6 is set in the vertical transport pipeline, and expander section bottom is provided with the hole 8 of taking out heavy foreign material.
When the vertical strength of powder was carried, when gas speed was lower than " the thiophene speed of choking ", powder began deposition.As shown in Figure 2, powder is to enter the vertical transport pipeline section under the air-flow effect of u in speed.After entering the expander section, air-flow velocity is that u reduces to " the thiophene speed of choking " near the powder vertical transport.Under this speed, after powder with certain initial velocity enters the expander section, under effect of inertia, upwards do decelerated movement, less powder still can pass through the expander section, the particle that diameter is big is under the effect of gravity and resistance on a small quantity, then begin to deposit in bottom, expander district, the bulky grain deposition causes the rear flow sectional area to reduce, wind speed increases, add little powder by the time effect of impact etc., reach new balance, bulky grain also passes the expander section reluctantly, enter normal pipeline section, under wind effect, be transferred.Heavy foreign material are than great, and former wind-force delivery speed u just is lower than its thiophene speed of choking, extremely difficult rising the when entering the vertical transport pipeline section, and being everlasting as big heavy foreign material, to carry long-time " dingdingdangdang " and the tube wall in pipeline section elbow to collide be exactly illustration.Enter the expander section, wind speed reduces suddenly, originally from-primary-to-junior-middle-school speed, is slowed down rapidly and is transferred under gravity and drag effect with regard to very little heavy foreign material, because of powder is under the thiophene speed of choking, impact forces is very little, can not change the falling bodies state of heavy foreign material, sometimes through repeatedly rising and falling, heavy foreign material drop in the expander section pipe weir the most at last, are trapped in for a long time in the expander section pipe weir and no longer are transferred.Regularly open the hand hole under the expander section pipe weir, can from the powder that gathers, find separated heavy foreign material.
Claims (2)
