Description

TECHNICAL FIELD

[0001] The utility model relates to solid particle conveying technical field, concretely is a kind of powder centrifugal separation device. BACKGROUND

[0002] At present, solid particle conveying usually adopts dense phase or dilute phase gas conveying, process is as shown in Figure 1 Material enters storage tank and falls into sending tank in batches, and is sent to remote material bin in batches by gas pressurization one tank by one tank. In the conveying process, particles collide and rub with each other, and also exist friction between pipe wall, so a large amount of powder is generated, which is particularly serious in the case of long conveying distance. These powders mixed into the next process have adverse effects on product quality, and the current conveying system manufacturers cannot remove the powders. SUMMARY

[0003] To solve the above technical problems, the utility model provides a kind of powder centrifugal separation device, which can smoothly separate powder and solid, and will not affect subsequent processes.

[0004] The technical scheme is as follows: a kind of powder centrifugal separation device, characterized in that it comprises a separation arc-shaped groove and a groove cover, the lower opening of the separation arc-shaped groove is connected to a feed connector, and the upper opening is connected to a discharge connector, the groove cover is connected to the outer side of the separation arc-shaped groove, and the outer side of the separation arc-shaped groove is provided with a mesh hole near one end of the discharge interface.

[0005] Further characterized in that the separation arc-shaped groove comprises a dispersion groove body and an arc-shaped cover plate, the groove cover is connected to the arc-shaped cover plate, and the mesh hole is provided in the arc-shaped cover plate.

[0006] The rear end of the groove cover is a closed structure and is connected to an elbow pipe.

[0007] The feed connector and the discharge connector each comprise a flat transition connector and a connecting flange, one end of the flat transition connector is circular and fixedly connected to the connecting flange, and the other end is rectangular and connected to the separation arc-shaped groove.

[0008] After using the utility model, solid material with powder enters the separation arc-shaped groove from the feed connector and moves in an arc, the powder passes through the mesh hole into the groove cover under the action of centrifugal force and gas pressure difference, and can be collected separately. Solid particles cannot pass through the mesh hole and are finally sent out from the discharge connector into the subsequent material bin, so that the powder and solid are smoothly separated, and the subsequent processes are not affected.

[0015] As shown in Figures 1 to 6 A kind of powder centrifugal separation device, it includes separation arc groove 1, groove cover 2, the lower part opening of separation arc groove 1 is connected feed joint 3, upper part opening is connected discharge joint 4, groove cover 2 is connected the outer side of separation arc groove 1 and the outer side of separation arc groove 1 is close to the end of discharge interface and is equipped with mesh 5, separation arc groove 1 includes dispersion groove body 1-1 and arc cover plate 1-2, groove cover 2 is connected on arc cover plate 1-2 and mesh 5 is equipped in arc cover plate 1-2, the rear end of groove cover 2 is close-end structure and is connected elbow pipe 6.

[0016] Feed joint 3 and discharge joint 4 all include flat transition pipe 7 and connecting flange 8, one end of flat transition pipe 7 is circular and is fixedly connected with connecting flange 8, the other end is rectangular and is connected with separation arc groove 1.

[0017] When implementing, remove the end arc pipeline of the original conveying pipeline to the bin, connect feed joint 3 and discharge joint 4 of the application, weld dispersion groove body 1-1, can also be welded as a whole in advance, then install arc cover plate 1-2 and groove cover 2, fasten arc cover plate 1-2 and groove cover 2 together with bolt fastener, add sealing gasket or sealing glue in the middle, so that it does not leak particles and powder, then weld elbow pipe 6 to the interface of groove cover 2, connect cyclone separator or cloth bag to collect powder behind.

[0018] The working principle is as follows: when the material enters the device from the conveying pipeline, it passes through the feed joint 3, the material flow type is changed from circular to flat shape by the round-square variable diameter, then does arc motion in the separation arc groove 1, the flat flow type can disperse the granular material, uniformly distribute, shorten the moving distance of the powder in the flow channel, after reaching the end, the powder flows into the groove cover 2 through the mesh 5 on the upper arc cover plate 1-2 under the action of centrifugal force and gas pressure difference, finally through the elbow pipe 6, the powder can be sent into the rear cyclone separator or cloth bag to collect the powder; the solid granular material is blocked by the mesh 5, continues to forward conveying, falls into the bin through the discharge joint 4. The application separates the powder from the granular material by centrifugal force and gas pressure difference, the conveying gas is released in advance, the pressure bearing of the bin and the gas discharge resistance are reduced.
