[0002] Pneumatic conveying system is a device that uses gas as power to transport powder materials from one place to another in a closed pipeline along the airflow direction through a sealed pipeline. It is a specific application of fluidization technology and is widely used in fine chemicals, polymer material synthesis and processing, battery manufacturing, food processing, metallurgy, cement building materials, coal-fired power plants and other departments. In the material transportation process of the carbon industry and aluminum industry, high-pressure airflow is often used to transport solids in pipelines.

[0003] At present, the gas-solid separation method used in gas conveying systems is mainly achieved by intercepting with inclined baffles. The baffles block the solid materials, slowing down the solid materials' sinking and reducing the pressure of the high-pressure gas. However, this method has the technical problem of insufficient interception of solid materials, and some solid materials will continue to be discharged along with the high-pressure gas.

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model is a gas-solid separation device for a gas conveying system. The baffle intercepts the fixed materials entering through the feed port, reduces the pressure of the high-pressure gas, and cooperates with the filter screen plate arranged at the inlet end of the exhaust port to further intercept the solid materials. This can ensure that the solid materials sink completely, improve the thoroughness of gas-solid separation, and even improve the efficiency of the gas conveying system.

[0013] 2. The utility model is a gas-solid separation device for a gas conveying system. By arranging a wind-driven rotating structure on one side of the feed port, it can obtain rotational power with the assistance of high-pressure gas.

The spring telescopic rod is used to provide a linear rebound for the filter screen, and the rubber sleeve is deformable to seal. The filter screen can achieve a vibration stripping effect when filtering and separating solid materials. This can improve the thoroughness of solid material removal on the filter screen, prevent blockage, and facilitate sinking and collection.

[0015] 4. The utility model is a gas-solid separation device for a gas conveying system. By setting a material dispersion structure, it uses the rotational force of the wind-driven rotating structure to stir and disperse the sinking solid materials, and improves the dispersion of the solid materials. This can avoid the technical problem of unsmooth material discharge caused by agglomeration when the solid materials sink and accumulate. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] A wind-driven rotating structure 6 is provided in the separation tank 1, and the wind-driven rotating structure 6 corresponds to one side of the feed port 2. A material dispersion structure 7 is provided at the bottom of the wind-driven rotating structure 6. A rubber sleeve 8 is fixedly connected to the inner top of the separation tank 1, and a filter screen plate 9 is fixedly connected to the bottom end of the rubber sleeve 8. The rubber sleeve 8 can be deformed and bent adaptively, so that the sealing can be ensured when the filter screen plate 9 moves. The filter screen plate 9 corresponds to the position directly below the exhaust port 4. The filter screen plate 9 can be used to intercept solid materials in the high-pressure gas discharged through the exhaust port 4. A spring telescopic rod 10 is fixedly connected to the edge of the top of the filter screen plate 9. The end of the spring telescopic rod 10 facing away from the filter screen plate 9 is fixedly connected to the inner top position of the separation tank 1. In the present application, the spring telescopic rod 10 It consists of a telescopic rod and a spring sleeved on the telescopic rod, the two ends of the telescopic rod are respectively fixedly connected to the filter screen plate 9 and the separation tank 1, the bottom of the filter screen plate 9 is rotatably connected with a scraper 11, and the scraper 11 is in active contact with the filtering surface of the filter screen plate 9, and the scraper 11 can be used to remove solid materials attached to the filtering surface of the filter screen plate 9. When the high-pressure gas is discharged through the exhaust port 4, a small amount of solid materials is carried by the high-pressure gas through the exhaust port 4. At this time, the filter screen plate 9 can filter and intercept the solid materials. In order to avoid the reduction of the filtering performance of the filter screen plate 9, the filtering surface of the filter screen plate 9 is scraped by the scraper 11, which can facilitate the cleaning of the attached solid materials. A linear telescopic member 12 is provided on the scraper 11 and the wind-driven rotating structure 6.

[0026] The wind-driven rotating structure 6 includes a support rod 61 fixedly connected to the inner wall of the separation tank 1, a driving shaft 62 rotatably connected to the support rod 61, and a rotating blade 63 fixedly connected to the driving shaft 62.

[0027] The material dispersion structure 7 includes a shaft 71 fixedly connected to the bottom end of the driving shaft 62 and a stirring blade 72 fixedly connected to the shaft 71.

In this way, during the vertical movement of the filter screen plate 9, it can be ensured that the driving shaft 62 can provide rotational power to the scraper 11 in real time, so that the scraper 11 can scrape the solid materials attached to the filtering surface of the filter screen plate 9.

[0029] Example 2

[0030] The difference between this embodiment and embodiment 1 is that, in conjunction with Figure 3 The utility model provides a gas-solid separation device for a gas delivery system, which also includes a trigger rod 14 and a rotating lifting structure 15. The trigger rod 14 is fixedly connected to the outer surface of the filter screen plate 9, and the rotating lifting structure 15 is arranged on the driving shaft 62.

The top of the top plate 152 is rounded, and the top plate 152 is in active contact with the trigger rod 14 .

[0032] Specifically, when the drive shaft 62 drives the scraper 11 to perform a rotational scraping action, the fixed ring 151 can drive the top plate 152 to move in a circular motion. Since the trigger rod 14 is on the circular path of the top plate 152, when the top plate 152 contacts the trigger rod 14, the elasticity of the spring telescopic rod 10 is utilized, so that the filter screen plate 9 can be lifted. This action can give the filter screen plate 9 a certain vibration, thereby providing a vibration removal effect for the solid materials attached to the filter screen plate 9.
