Specific embodiment
Below in conjunction with the embodiment of the present invention and accompanying drawing, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
As shown in figure 1, a kind of gear type fine coal pressure conveyer device that the present invention is provided, including driving gear 3, driven tooth
Wheel 7, fine coal entrance 1, fine coal outlet 5 and housing 2；While also including wiper 4.
Wherein, driving gear 3 is placed in housing 2 with driven gear 7, fine coal entrance 1 and fine coal outlet 5 respectively with housing 2
Connection, and it is located at the offside of housing 2 respectively, centre is separated with driving gear 3 and driven gear 7；Driving gear 3 and driven gear 7
Engagement, and powdery solid is transported to from fine coal entrance 1 by fine coal outlet 5 by rotation, realize the conveying of powdery solid, such as fine coal
Conveying；Wiper 4 can be removed and be attached to driving gear 3 and the attachment on 7 surface of driven gear, with ensure driving gear 3 with
The stable engagement of driven gear 7, while protect the flank of tooth of driving gear 3 and driven gear 7.
Specifically, the ambient pressure of fine coal entrance 1 is atmospheric pressure environment, and the ambient pressure of fine coal outlet 5 is environment under high pressure, pressure
Power scope is 4.3-8.5Mpa；Driving gear 3 is rotated under actuating unit drive, and drives driven gear 7 to rotate by engaging；
Driving gear 3 is at a fully engaged with driven gear 7, and engagement place forms sealing so that the fine coal from fine coal entrance 1 will not be from gear
Engagement place passes through, while also causing the gases at high pressure of the fine coal outlet 5 of environment under high pressure not reveal from gear engagement place；Driving tooth
Wheel 3 points to fine coal entrance 1 with the disengaged direction of driven gear 7, from the fine coal of fine coal entrance 1 fall into driving gear 3 with driven
The between cog of gear 7, the fine coal for falling between cog enters into fine coal outlet 5 by the rotation of gear from the side for pressing close to housing 2；Actively
With gap between gear 3, driven gear 7 and housing 2, the interstice coverage is that 0.01-10mm, it is preferable that the interstice coverage is
0.1-1mm, and the gap is changing value.This device is engaged with driven gear 7 by driving gear 3 and rotated realizes fine coal from low
Pressure ring border is to the transport of environment under high pressure.
Wherein, the presence in gap causes driving gear 3 and 7 stable rotation of driven gear, while fine coal exports 5 high-pressure side gas
The gap that knows from experience between driving gear 3, driven gear 7 and housing 2 is revealed to 1 low-pressure end of fine coal entrance, and is revealing
During can run into on-way resistance and the local resistance of gap generation, the leakage pressure due to the presence gap of resistance progressively drops
Low until close by force with normal pressure side pressure, the reduction gas volume due to pressure persistently increases that (gas produces swollen in the process
Swollen), therefore its actual volume flow is persistently increased, and can increase on-way resistance and local resistance further.
But the rotation reason due to gear, the gas of leakage with the direction of pinion rotation, to high-pressure side mass motion,
And while to low-pressure end leakage, it is finally reached a relatively steady state, leakage speed and mass motion similar rate, i.e. gas
Body is no longer revealed to outward leakage or slightly, forms sealing.
Specifically, the surface of driving gear 3 and driven gear 7 is coated with gear coating 6, such as high-hardness ceramic coating.Right
The tooth surface of driving gear 3 and driven gear 7 is processed, and makes tooth have the high surface of extremely smooth and hardness, it is to avoid tooth table
The bonding of face solid matter and the damage of tooth surface, improve safety use and durability that device is used.
Specifically, as shown in Fig. 2 driving gear 3, driven gear 7 are respectively provided with one or more wipers 4；Wiper 4 is located at
Before the meshing point of driving gear 3 and driven gear 7.To the attachment on gear before driving gear 3 is engaged with driven gear 7
Thing is cleared up, to ensure stable engagement and protect the flank of tooth.
Wherein, wiper 4 can rotate and with multiple brush teeths, such as 4 brush teeths, and with the rotation of wiper 4, brush teeth can extend into
In gap between driving gear 3, two teeth of driven gear 7, which is cleared up.The wiper 4 for being contacted with driving gear 3 is rotated
Direction is identical with 3 direction of rotation of driving gear, 4 direction of rotation of wiper for contacting with driven gear 7 and 7 direction of rotation of driven gear
Identical, so relative cleaning campaign being formed in tooth surface, cleans cleaner；Wiper 4 adopts high-abrasive material, to ensure wiper
4 durability degree.
Traditional gear structure for conveying is normally only used for conveying gas or liquid, it is impossible to for pressurized delivered solid or
Gas-solid mixture, which main reason is that the engagement process of gear can not have solid matter to be present in the surface of tooth, otherwise can be right
Tooth produces irreversible damage, and a kind of gear type fine coal pressure conveyer device in the present invention, by arranging wiper 4, in tooth
Fine coal before wheel engagement to adhering on gear is cleared up, and is enabled pressurized delivered solid or gas-solid mixture, is entered one
Step, using the gear coating 6 as high-hardness ceramic coating, make fine coal be difficult to be attached to tooth surface.
With reference to the gear type fine coal pressure conveyer device in the embodiment of the present invention, the conveying of conveyer device is described in detail
Process.
Driving gear 3 is turned clockwise (shown in Fig. 1) under actuating unit drive, drives driven gear 7 inverse by engaging
Hour hands rotate, and enter from fine coal entrance 1 with the mixture of noble gases from the fine coal at normal pressure end, and fine coal drops into gear between cog
In, as the rotation of driving gear 3 and driven gear 7 is transported to the fine coal outlet of high-pressure side between two side gears and housing 2
5, complete conveying.
Left side 4 rotate counterclockwise of wiper, right side wiper 4 turns clockwise, and engages it in driving gear 3 with driven gear 7
The front attachment to tooth surface is cleared up.
Pass through the gap between gear and housing 2 from the high-pressure side gas of fine coal outlet 5 to reveal upwards, due to hindering along journey
Power rotates the impact of the motion in opposite direction with leakage for bringing with the effect of local resistance and gear, reaches one eventually relatively
Stable state, is revealed speed and is no longer revealed to outward leakage or slightly with mass motion similar rate, i.e. gas, formed close
Envelope.
The above, only certain specific embodiments of the invention, but protection scope of the present invention is not limited thereto,
Any those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, all
Should be included within the scope of the present invention.Therefore, protection scope of the present invention should be with the scope of the claims
It is defined.
