[0002] The positive pressure conveying shut-off fan is a key equipment used in the positive pressure pneumatic conveying system. It is mainly used to control the flow of materials and ensure the airtightness of the pneumatic conveying process. In the positive pressure pneumatic conveying system, the shut-off fan is usually installed at the starting point or middle position of the conveying pipeline, and the rotating blades or rotors inside it are driven by the motor to evenly convey the materials.

[0003] Positive pressure conveying fan is often used in the process of material transportation. However, after long-term use, the positive pressure conveying fan will inevitably be worn and produce gaps, causing part of the pressure to be released from the wear surface of the fan to the small upstream silo. When the pressure reaches a certain value, material lifting will occur, resulting in the inability of the dried material to enter the conveying pipeline normally. Long-term accumulation will create the risk of clogging the entire conveying pipeline or damaging the conveying equipment.

[0004] Therefore, we make improvements to this and propose a method of installing a positive pressure relief pipe. Utility Model Content

[0036] Example 1

[0037] Please refer to Figure 1-4A positive pressure relief pipeline is installed, including a drying device 1 and a storage tank 11. The left and right sides of the drying device 1 are fixedly connected with a feed pipe 12. The lower end of the feed pipe 12 is fixedly connected to the storage tank 11. The feed pipe 12 is connected to the drying device 1 and the storage tank 11 respectively. A pressure relief part for pressure relief is fixedly connected between the drying device 1 and the storage tank 11. A cleaning part is rotatably connected to the inner top surface of the storage tank 11. The upper surface of one of the feed pipes 12 is connected with a feeding bin 14, the lower surface of the storage tank 11 is connected with a positive pressure conveying fan 13, the lower surface of the positive pressure conveying fan 13 is connected with a feed pipe 2 15, and the insides of the feed pipe 12 and the feed pipe 2 15 are both provided with spirals. The pressure relief component includes a pressure relief pipe 2, the upper end of which is fixedly connected to the right side of the drying device 1, and the lower end of which is fixedly connected to the upper surface of the storage tank 11. The pressure relief pipe 2 is connected to the drying device 1 and the storage tank 11. A filter screen 21 is installed on the top surface of the storage tank 11 below the pressure relief pipe 2.

[0038] Implementation process: the material is discharged from the feeding bin 14 into the interior of the feed pipe 12, and then transported to the interior of the drying equipment 1 through the spiral inside the feed pipe 12. The drying equipment 1 works to dry the material, and then the material is transported to the interior of the storage tank 11 through the spiral inside the feed pipe 12. Because a positive pressure conveying fan 13 is provided between the storage tank 11 and the feed pipe 2 15, the material is evenly transported from the interior of the storage tank 11 to the interior of the feed pipe 2 15 under the action of the positive pressure conveying fan 13, and then transported through the spiral inside the feed pipe 2 15. The pressure relief pipe 2 is respectively connected to the drying equipment 1 and the storage tank 11, which can effectively release the pressure relief caused by the wear of the positive pressure conveying fan 13. At the same time, the filter screen 21 is provided to prevent the material from entering the pressure relief pipe 2 and causing blockage. The spiral belongs to the well-known field and is not explained here.

[0039] Implementation benefits: It realizes the drying and transportation of materials, improves production efficiency, and reduces the impact of production capacity caused by blockage and the increase in labor costs.

[0040] Example 2

[0041] The cleaning part includes a rotating rod 3, which is rotatably connected to the inner top surface of the storage tank 11, a cleaning brush 31 is fixedly connected to the outer surface of the rotating rod 3, and a bevel gear 1 32 is fixedly connected to the lower end of the rotating rod 3.

[0042] Implementation process: The pressure relief of the wear surface of the positive pressure conveying fan 13 drives the impeller 35 to rotate, and the rotation of the impeller 35 drives the rotating shaft 34 and the bevel gear 2 36 to rotate synchronously. Because the bevel gear 2 36 is meshingly connected with the bevel gear 1 32, the rotation of the bevel gear 2 36 drives the bevel gear 1 32 and the rotating rod 3 fixedly connected to the bevel gear 1 32 to rotate, thereby driving the cleaning brush 31 to rotate synchronously. The material on the surface of the cleaning brush 31 is continuously cleaned by the rotation of the cleaning brush 31 to prevent the material from clogging the filter 21.

[0043] Implementation benefits: The surface of the filter screen 21 is cleaned.
