As shown in Figure 1, embodiment one of the present utility model provides a kind of powder delivery system, comprises hopper 1, gear type pump 2, mixer 3, transfer line 4, aggregate bin 5 and dust exhaustor 6; Hopper 1, gear type pump 2, mixer 3, transfer line 4 and aggregate bin 5 connect successively; Wherein, hopper 1 is connected with the feed end of gear type pump 2;
Hopper 1 is connected with gear type pump 2 by the top of gear type pump 2; Mixer 3 is connected with gear type pump 2 by the below of gear type pump 2;
Be provided with pressure gas entrance 12 on the mixer 3; Dust exhaustor 6 is arranged on the top of aggregate bin 5.
By gear type pump 2 powder is delivered to mixer 3 from hopper 1, in mixer 3, passes into pressure gas, and drive powder through transfer line 4 arrival aggregate bins 5 as propulsion source.In this process, because gear type pump 2 has unidirectional conveying function, its feed space 9 is that constantly engaged gear cluster 8 cuts off with discharge chamber 10, can only move to transfer line 4 so pressure gas enters mixer 3 rear air-flows, and then the powder in the drive mixer 3 is to transfer line 4 motions.Overall process middle gear pump 2 is responsible for playing the partition effect when rotation is fed into mixer 3, prevents that pressure gas from directly flowing to hopper 1; Pressure gas is as the power that powder is delivered to aggregate bin 5 by mixer 3.Be deposited on aggregate bin 5 bottoms at arrival aggregate bin 5 rear powders, the pressure of pressure gas is discharged by dust exhaustor 6.Powder can be finished conveying under airtight environment like this, can not be diffused in the atmosphere, and human body or equipment are caused damage.
As shown in Figure 2, embodiment two of the present utility model provides another kind of powder delivery system, comprises hopper 1, gear type pump 2, mixer 3, transfer line 4, aggregate bin 5 and dust exhaustor 6; Hopper 1, gear type pump 2, mixer 3, transfer line 4 and aggregate bin 5 connect successively; Wherein, hopper 1 is connected with the feed end of gear type pump 2;
Hopper 1 is connected with gear type pump 2 by the top of gear type pump 2; Mixer 3 is connected with gear type pump 2 by the below of gear type pump 2;
Be provided with pressure gas entrance 12 on the mixer 3; Dust exhaustor 6 is arranged on the top of aggregate bin 5.
Because discharge chamber 10 communicates with mixer 3, so the gaseous tension in the discharge chamber 10 can be more much larger than feed space 9.And the position that begins to mesh of intermeshing two gears is positioned at discharge chamber 10 1 sides, the position of finishing engagement is positioned at feed space 9 one sides, so the air pressure of the engagement place of two gears equates with discharge chamber 10, equally greater than feed space 9, when finishing engagement, two gears exist the air pressure of engagement place to discharge like this, powder in the feed space 9 is pushed away gear, because the conveying of gear type pump 2 is endlessly processes, therefore this air pressure can form endlessly thrust prevention powder near gear, cause blanking velocity slow, even cause putty.
In order to prevent that above-mentioned situation from occuring, and is provided with the relief hole 19 that communicates with the engagement place of two described gears on the shell 7.By arrange relief hole 19 can will retain the pressure gas of engagement place of two gears discharge, prevent from that these pressure gass are released to cause behind the feed space 9 to push powder, hinder blanking.
For fear of above-mentioned situation, also be provided with two cleaning hole 13 that are used for entering the gas that the powder between adjacent two teeth on the same described gear is blown off on the shell 7; Two cleaning hole 13 all communicate with discharge chamber 10; The all corresponding cleaning hole 13 of each described gear; And the projection of cleaning hole 13 in this gear sagittal plane is positioned at the scope that the path of motion of tooth in the sagittal plane of described gear of this gear covers.Like this cleaning hole is connected air inlet pipe and just the powder that remains between two teeth can be blown off, prevent residual.
Pressure gas is that the kinetic energy when relying on gas flow drives the powder motion and then reaches the purpose of carrying powder, so the kinetic energy of pressure gas is most important for the conveying of powder.Turning or meeting with the kinetic energy that can lose in a large number pressure gass when blocking, cause the powder fed distance to shorten, speed slows down, and cost increases.
Therefore, pressure gas entrance 12 and transfer line 4 coaxial settings.Pressure gas directly is connect by pressure gas entrance 12 enter transfer line 4, can not cause the kinetic energy waste.
Pressure gas is swiftly flowing high pressure gas, and its inner distribution of pressure is uneven, changes very fast.Carry out the flow velocity inequality that the powder conveying can cause powder if directly make it enter pipeline, and can cause transfer line 4 internal pressure overbalances, cause potential safety hazard.
For fear of the problems referred to above occurring, pressure gas entrance 12 is connected with pressure gas pipeline 14; Be provided with pressure maintaining valve 15 on the pressure gas pipeline 14.Can make the pressure of pressure gas more stable by pressure maintaining valve 15 is set, make the pressure in the transfer line 4 keep stable, can be not fluctuated.
For technology controlling and process and assessing the cost, often need various parameters are monitored in process of production.
The quantity of the rotating speed by gear type pump 2, the upper powder conveyor chamber 11 of gear and the volume of powder conveyor chamber 11 can draw the powder transfer rate of gear type pump 2 as calculated, realize the accurate measurement to powder, and precision can reach more than 98%.In the past gear type pump metering is mainly used in liquid meter.Now can be not residual by cleaning hole 13 rear solid powders are set, thus can realize metering feed to solid materials such as powders, solved in the powder course of conveying problem that the control for amount can't precisely detect in real time.
In order to realize that to the utilization of pressure gas actv., the feeding coal of mate gear pump 2 is monitored the compressed gas scale of construction, also be provided with meter 16 on the pressure gas pipeline 14, meter 16 is between pressure maintaining valve 15 and pressure gas entrance 12.So just, reached to powder with to the used compressed gas scale of construction and measured, be convenient to technique and cost control.
Every equipment has a resistance to compression limit, and equipment will be impaired when inside and outside differential pressure surpasses this limit, even also might cause personnel and property damage.And a lot of links of existence in process of production, these links connect each other, all linked with one another, and any one link goes wrong and all might cause intrasystem pressure to change.In case just can have an accident and pressure exceeds the resistance to compression limit of equipment self.And dust exhaustor 6 itself is exactly the inside and outside equipment of connected system in whole powder delivery system; therefore when changing greatly, internal system pressure is easy to exceed the tolerance range of dust exhaustor 6; if at this moment do not take the safety method dust exhaustor 6 will be impaired even damage, can't continue normal operation.
For fear of the generation of above-mentioned situation, the top of aggregate bin 5 also is provided with vacuum release valve 17.Can when aggregate bin 5 internal pressures surpass the resistance to compression limit, play a protective role like this, prevent that dust exhaustor 6 from damaging.
Because therefore the self-characteristic of powder also should be stored in powder in the airtight space after finishing conveying as far as possible.Aggregate bin 5 itself is one well to be selected, and the powder after the sedimentation can be directly in aggregate bin 5 interior storages.And be provided with blow-off valve 18 by the bottom at aggregate bin 5, can be from aggregate bin 5 bottoms directly powder that sedimentation is good discharge, directly use or pack is sealed up for safekeeping all very convenient.
Because native system is by pressure gas powder to be delivered to aggregate bin 5, pressurized air is also remaining after entering aggregate bin 5 kinetic energy, and this part kinetic energy can continue to act on the interior powder of aggregate bin 5, and it is blown afloat again.
In order to reduce the generation of above-mentioned situation, make as early as possible sedimentation of powder, transfer line 4 is connected with the top of aggregate bin 5.Can make like this powder have more space free to be deposited to aggregate bin 5 bottoms, and it is far away to enter the pressure gas of aggregate bin 5 powder good apart from sedimentation, and it is blown afloat again.
It should be noted that at last: above embodiment and embodiment only in order to the technical solution of the utility model to be described, are not intended to limit; Although with reference to aforementioned embodiments and embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned embodiments or embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make essence disengaging the utility model embodiment of appropriate technical solution or the spirit and scope of embodiment technical scheme.
