Abstract
The invention relates to a seal conveying negative-pressure effect device which comprises a power collector (1), a spiral conveyer (2) and a communicating tube (5), wherein the power collector (1) is communicated with the spiral conveyer (2) through the communicating tube (5), so that the inner part of the spiral conveyer (2) presents a negative-pressure state. According to the seal conveying negative-pressure effect device, the inner part of the spiral conveyer (2) also presents a tiny negative-pressure state. In the process of lead powder conveying, a blade of the spiral conveyer stirs the lead powder. When the powder flies, the flying powder can be brought to a spiral tail part through negative-pressure air in the communicating tube and finally settles down, and the lead powder cannot leak to the outer part to cause pollution even if a viewport of the spiral conveyer is opened to maintain. The seal conveying negative-pressure effect device has the efficacies of cleaning, environment protection and conservation.
Description
Technical field
The present invention relates to a kind ofly when lead powder sealing is carried, be used for the unexpected device of revealing after the lead powder course of conveying prevents to cause powder spreading because of stirring, specifically is that the negative pressure effects device is carried in a kind of sealing.
Background technology
Collect in the course of conveying at lead powder, lead powder is promoted through the conveyor screw blade by following in the leak free conveyor screw through the rotary unloading valve in the powder collector, delivers in the lead powder storage warehouse.In course of conveying, blade stirs the easy powder spreading of lead powder, if when the conveyor screw poor sealing maybe need be opened the inspection of conveyor screw cephalic inspection mouth, the lead powder of being kicked up can be gone out to overflow by slit or porthole, is leaked in the air, causes serious pollution.
Summary of the invention
The present invention provides a kind of sealing to carry the negative pressure effects device, has overcome the dust that causes because of conveyor screw blade stirring airborne dust in the prior art overflows pollution from porthole or slit drawback.
Technical scheme of the present invention:
The negative pressure effects device is carried in a kind of sealing, comprises powder collector 1 and conveyor screw 2, also comprises cross over pipe 5, said through cross over pipe 5 with powder collector 1 and conveyor screw 2 UNICOMs, make to demonstrate negative pressure state in the conveyor screw 2.
Said cross over pipe 5 one end UNICOM powder collector 1 bottoms, cross over pipe 5 other end UNICOM conveyor screw 2 afterbodys.
Said conveyor screw 2 tops are provided with porthole 3, and conveyor screw 2 belows are provided with powder mouth 4 under the conveyor screw.
Connect through rotary unloading valve 6 between said powder collector 1 and the conveyor screw 2.
The invention has the beneficial effects as follows:
The present invention makes through cross over pipe and also demonstrates small negative pressure state in the conveyor screw; In carrying the lead powder process; The conveyor screw blade stirs lead powder; When producing powder spreading, the negative pressure wind in the cross over pipe can bring back to the spiral afterbody with the lead powder of kicking up and settle down at last, even lead powder can not leak yet and pollutes when opening the maintenance of conveyor screw porthole.Sealing of the present invention carries the negative pressure effects device to have the effect of cleaning, environmental protection, saving.
Description of drawings
Fig. 1 is an arrangement structure front schematic view of the present invention.
Fig. 2 is an arrangement texture edge scheme drawing of the present invention.
Among the figure: 1 is that powder collector, 2 is that conveyor screw, 3 is that porthole, 4 is that powder mouth under the conveyor screw, 5 is that cross over pipe, 6 is the rotary unloading valve.
The specific embodiment
Following the present invention will combine the embodiment in the accompanying drawing to do further description:
Like Fig. 1, Fig. 2, the negative pressure effects device is carried in a kind of sealing, comprises powder collector 1 and conveyor screw 2, also comprises cross over pipe 5, said through cross over pipe 5 with powder collector 1 and conveyor screw 2 UNICOMs, make to demonstrate negative pressure state in the conveyor screw 2.
Cross over pipe 5 one end UNICOM powder collector 1 bottoms, cross over pipe 5 other end UNICOM conveyor screw 2 afterbodys.
Connect through rotary unloading valve 6 between powder collector 1 and the conveyor screw 2.
The present invention is like diagram; Powder collector 1 is the gathering-device of lead powder, presents negative pressure state in the powder collector 1 all the time, manages conveyor screw 2 and powder collector 1 UNICOM with UNICOM 5; Make like this and also demonstrate small negative pressure state in the conveyor screw 2; In carrying the lead powder process, conveyor screw 2 blades stir lead powder, when producing powder spreading; Negative pressure wind can bring back to conveyor screw 2 helicallobe afterbodys with the lead powder of kicking up and settle down at last, even lead powder can not leak yet and pollutes when opening the maintenance of conveyor screw 2 portholes 3.
Embodiment recited above describes preferred implementation of the present invention; Be not that design of the present invention and scope are limited; Do not breaking away under the design concept prerequisite of the present invention; Common engineering staff make technical scheme of the present invention in this area various modification and improvement all should fall into protection scope of the present invention, and the technology contents that the present invention asks for protection all is documented in claims.
