However, in actual use, the compound fertilizer raw materials are prone to corrosion of the belts. In addition, there will be material overflow and dust splashing during the transportation process, which ultimately leads to a poor production environment. This needs further improvement.

[0026] The following is combined with Figure 1-3This application is described in further detail.

[0027] Example 1

[0028] A chute-type gas delivery structure, such as Figure 1 and Figure 2 As shown, it includes an inclined pipe fitting 1, which adopts a high-pressure vinyl chloride pipe or a high-pressure polypropylene pipe with good corrosion resistance. A feed port 2 is opened at the top of the upper end of the pipe fitting 1, and a vertical downward feed pipe 3 is provided at the feed port 2. The lower end of the pipe fitting 1 is penetrated to form a discharge port 4. At the same time, an isolation layer 5 with the same inclination angle as that of the pipe fitting 1 is provided, and a through hole 6 is provided on the isolation layer 5. A material flow layer 7 for the flow of particulate material is formed above the isolation layer 5, and a compressed air flow layer 8 is formed below the isolation layer 5. The compressed air flows from the upper end of the pipe fitting 1 to the lower end, so that the material enters the pipe from the feed pipe 3 and flows downward in the material flow layer 7. During this period, the compressed air plays a role in promoting the flow of the material. The aperture of the through hole 6 is smaller than the diameter of the particulate material. The through holes 6 are densely distributed on the isolation layer 5, and the particulate material cannot fall into the compressed air flow layer 8 below.

[0029] When the granular material is being conveyed, it is inside the closed pipe 1, which effectively suppresses the overflow of dust. The material falls under the action of its own gravity. During this period, the compressed air promotes the conveying of the material. At the same time, the flow of compressed air can also prevent the material from being blocked in the pipe, achieving good conveying while creating a good and clean production environment. It has made a thorough improvement on the stubborn environmental pollution problem in the current production and conveying links. During the material conveying period, it will not cause pollution to the external environment, and the production workshop can be kept clean and tidy.

[0030] like Figure 1 As shown, an air inlet 9 is formed through one end of the pipe 1 at a higher position, and an air inlet pipe 10 is connected to the air inlet 9. A sleeve 11 is provided at the end of the air inlet pipe 10 for plugging into the end of the pipe 1. An end of the air inlet pipe 10 away from the pipe 1 is connected to an air storage tank 12. A large amount of compressed air is stored in the air storage tank 12. The compressed air in the air storage tank 12 enters the pipe 1 through the air inlet pipe 10 to realize the injection and flow of compressed air.

[0031] like Figure 1 As shown, a return air pipe 13 is provided at the lower end of the pipe fitting 1, one end of the return air pipe 13 is connected to the compressed air flow layer 8 inside the pipe fitting 1, and the other end of the return air pipe 13 is connected to the air inlet pipe 10, so that during specific use, the compressed air in the compressed air flow layer 8 can be returned to the air inlet pipe 10 through the return air pipe 13 for recycling, reducing waste and achieving the purpose of greater energy saving; and a one-way valve 14 is provided on both the return air pipe 13 and the air inlet pipe 10 to ensure that the compressed air flows in one direction and avoid the phenomenon of compressed air backflow.

[0032] like Figure 1 As shown, an arc-shaped guide portion 15 is provided at the end of the isolation layer 5 corresponding to the feed port 2, one end of the guide portion 15 is fixed to the inner wall of the pipe 1, and the other end is fixed to the isolation layer 5. The guide portion 15 is located below the feed port 2, so that on the one hand the material can play a buffering and guiding role, and on the other hand it can also play a guiding role for the compressed air, so that the material can enter the material flow layer 7 well, and the compressed air can enter the compressed air flow layer 8 well; in this embodiment, the space of the compressed air flow layer 8 is smaller than the material flow layer 7, so that the material flow layer 7 can accommodate more materials for transportation, and the compressed air flow layer 8 has a smaller space and a greater pressure, thereby achieving a better transportation effect and clearing blockages.

[0033] Example 2

[0034] A chute-type gas delivery structure, such as Figure 3 As shown, the main difference from Example 1 lies in the different structure of the return air pipe 13. In this embodiment, a dust box 16 is provided on the return air pipe 13, and a channel 17 for communicating with the return air pipe 13 is provided in the dust box 16, and a filter bag 18 is provided in the channel 17. Since some powder is inevitably generated during the transportation of particulate material, the powder will flow into the return air pipe 13. The design of the filter bag 18 can filter the powder to avoid the powder continuing to circulate in the pipeline and causing it to accumulate more and more.

[0035] In this embodiment, two dust boxes 16 are arranged horizontally in parallel. In other embodiments, multiple dust boxes 16 are provided, and the dust boxes 16 are horizontally slidably connected to the return air pipe 13. When a large amount of powder is accumulated in one dust box 16, the other dust box 16 is switched to be connected to the return air pipe 13 by sliding. At this time, the powder in the dust box 16 can be cleaned, and the return air pipe 13 can be kept in a continuous working state, and the production efficiency will not be affected by the cleaning of the powder.

[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
