Description

Technical Field

[0001] This application relates to the field of pneumatic conveying devices, and in particular to a pneumatic conveying start-up concentration stabilizer. Background Technology

[0002] Pneumatic conveying is a technology that uses the flow of air to transport solid particles or powdered materials. Its principle is based on fluid mechanics, using the kinetic energy of gas to transport materials along pipelines from the starting point to the destination.

[0003] Traditional pneumatic conveying uses axial flow conveying, where compressed air and materials move along the pipeline, usually in a straight line. Because the material moves quickly in a straight line, the elbows wear out severely (on the output pipe wall), resulting in high replacement costs and wasting manpower and time, thus reducing the efficiency of conveying. Therefore, this application proposes a pneumatic conveying start-up concentration stabilizer. Utility Model Content

[0004] The purpose of this application is to address the technical problems identified in the background section by proposing a pneumatic conveying swirl concentration stabilizer.

[0005] The technical solution of this application: A pneumatic conveying swirl concentration stabilizer, comprising a steel pipe and a first air inlet pipe connected to its input end, and further comprising:

[0006] An outer shell is fixedly connected to the side wall of a steel pipe. Several guide vanes arranged in a ring are fixedly connected to the inner wall of the outer shell. The guide vanes penetrate the inner wall of the steel pipe and extend into the interior of the steel pipe. An air source is connected to the end of the outer shell.

[0007] Preferably, a second air intake pipe is connected through the side wall of the outer casing. The second air intake pipe is located on one side of the end of several guide vanes. The air source is connected to the second air intake pipe, and the second air intake pipe is installed through an air intake flange.

[0008] Preferably, the output end of the housing extends to the output end of the steel pipe, and the inner wall of the output end of the housing and the outer wall of the steel pipe form an air outlet.

[0009] Preferably, the diameter of the output end of the housing gradually decreases, and the output end of the housing is supported by a discharge port flange.

[0010] Preferably, the input end of the steel pipe is supported by a loose flange for mounting the first air inlet pipe, and the first air inlet pipe compressor is connected to an external compressor and feed pipe.

[0011] Preferably, the output end of the steel pipe is connected to an external discharge pipe.

[0012] Compared with the prior art, this application has the following beneficial technical effects:

[0013] This application connects an outer shell to the outer wall of a steel pipe, and connects several annularly arranged guide vanes to the inner wall of the outer shell to output gas into the interior of the outer shell. The gas is conveyed in a rotating manner, and the airflow assists the material in a cyclone manner, which can reduce the material pickup speed in the pipeline, use less air to carry the material, and make the material and gas fully mixed, thus saving gas. After saving gas, there is less airflow inside the steel pipe, and the conveying is slower, thereby effectively reducing the wear of the output pipeline.

[0014] In this application, the guide vanes penetrate the steel pipe and extend into the interior of the steel pipe, forming a spiral flow state inside the steel pipe. At this time, the double swirling flow state can save gas to a greater extent and further reduce the wear on the output pipe. Attached Figure Description

[0024] Example

[0025] like Figures 1-3 As shown, this application proposes a pneumatic conveying swirl concentration stabilizer, comprising a steel pipe 3 and a first air inlet pipe 1 connected to its input end. The input end of the steel pipe 3 is supported by a loose flange 2 for mounting the first air inlet pipe 1, and the compressor of the first air inlet pipe 1 is connected to an external compressor and a feed pipe. The output end of the steel pipe 3 is connected to an external discharge pipe. It also includes a housing 4 fixedly connected to the side wall of the steel pipe 3. A plurality of annularly arranged guide vanes 5 are fixedly connected to the inner wall of the housing 4. The guide vanes 5 penetrate the inner wall of the steel pipe 3 and extend into the interior of the steel pipe 3. An air source is connected to the end of the housing 4. A second air inlet pipe 9 is connected through the side wall of the housing 4. The second air inlet pipe 9 is located on one side of the end of the plurality of guide vanes 5. The air source is connected to the second air inlet pipe 9, and the air source is generated by an external compressor. The second air inlet pipe 9 is mounted via an air inlet flange 8.

[0026] Specifically, the output end of the outer casing 4 extends to the output end of the steel pipe 3, and the inner wall of the output end of the outer casing 4 and the outer wall of the steel pipe 3 form an air outlet 6. It should be noted that the diameter of the output end of the outer casing 4 gradually decreases, confining the incoming air inside the outer casing 4 and creating a swirling flow inside the outer casing 4, thereby driving the material inside the steel pipe 3 to swirl forward. The air outlet 6 is connected to the outside to avoid excessive air pressure inside the outer casing 4, which could lead to safety hazards. The output end of the outer casing 4 is supported by a discharge flange 7.

[0027] The working principle of this embodiment is as follows: When conveying through the steel pipe 3, compressed air enters the steel pipe 3 through the first inlet pipe 1, and the material also enters the steel pipe 3 at the same time; simultaneously, the compressed air enters the outer shell 4 through the second inlet pipe 9. Under the action of several guide vanes 5 inside the outer shell 4, the airflow inside the outer shell 4 forms a swirling state. After being accelerated through the tightened air outlet 6, it drives the material in the first inlet pipe 1 to swirl forward. Since several guide vanes 5 penetrate the inner wall of the steel pipe 3 and extend into the interior of the steel pipe 3, a swirling flow is also formed on the inner wall of the steel pipe 3, achieving the effect of double swirling flow inside and outside; the overall air consumption is reduced, the solid-to-gas ratio is increased, and the material conveying concentration is stable; after saving air, there is less airflow in the first inlet pipe 1, and the conveying is slower, thereby effectively reducing the pipe wear rate and extending the service life of the conveying equipment.

[0028] The above specific embodiments are merely preferred embodiments of this application. Based on the technical solutions of this application and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments. The above specific embodiments are merely explanations of this application and are not limitations on this application.
