[0025] The technical solutions of the embodiments of this application are briefly described below:

[0026] According to some embodiments, such as Figure 1 As shown, this application provides an air-material mixing device, the air-material mixing device comprising:

[0027] The intake manifold 9 and the nozzle 10 are provided inside the intake manifold 9. The outer wall of one end of the nozzle 10 is connected to the inner wall of one end of the intake manifold 9 to serve as an air inlet 11.

[0028] The hopper 2 and the first observation mirror 3 are provided. The top of the hopper 2 is provided with a feed inlet 1. The bottom of the hopper 2 is connected to the outer wall of the air intake pipe 9. The other end of the nozzle 10 extends to the outlet at the bottom of the hopper 2. The other end of the air intake pipe 9 is used for mixing and discharging. The first observation mirror 3 is provided on the outer wall of the hopper 2.

[0029] Based on the above embodiments, when the gas-feed mixing device is working, the air inlet 11 receives power from the blower. The blower sends gas into the air inlet 11 through the gas power source pipeline, and then from the air inlet 11 into the nozzle 10, and further into the main air intake 9. Because the nozzle 10 has a large inlet size and a small outlet size, and the main air intake 9 is larger than the nozzle 10 outlet size, the gas will accelerate and flow at high speed through the nozzle 10, forming a certain negative pressure vacuum in the main air intake 9, providing power for the subsequent mixing of feed and gas. The feed inlet 1 at the top of the hopper 2 receives feed, and the feed enters the main air intake 9 from the hopper 2. The feed and gas are fully mixed in the main air intake 9 to form a high-pressure gas-feed mixture, which is discharged through the other end of the main air intake 9, transporting the gas-feed mixture to the subsequent conveying pipeline.

[0030] The following is in conjunction with the appendix to this instruction manual. Figure 1 The preferred embodiments of this disclosure will be further described in detail below.

[0031] According to some embodiments, such as Figure 1 As shown, the gas-material mixing device also includes an interface 4. The hopper 2 is vertically arranged, and the two ends of the interface 4 are respectively connected to the bottom of the hopper 2 and the outer wall of the air inlet pipe 9.

[0032] Based on the above embodiments, when the gas-feed mixing device is working, the feed inlet 1 at the top of the feed hopper 2 receives the feed. The feed enters the feed hopper 2 under the action of gravity, and then the feed enters the air intake pipe 9 through the interface 4. The feed and gas are fully mixed in the air intake pipe 9 to form a high-pressure gas-feed mixture. Both the interface 4 and the air intake pipe 9 are inclined to facilitate the falling of the feed and to prevent the feed from backflowing.

[0033] According to some embodiments, such as Figure 1As shown, the gas-material mixing device also includes a diffuser pipe 5, one end of which is connected to the other end of the main air inlet pipe 9, and the other end of which is used for mixing and discharging.

[0034] Based on the above embodiments, since the diffuser 5 has a large inlet size and a small outlet size, the gas-material mixture will be further pressurized and discharged after passing through the diffuser 5.

[0035] According to some embodiments, such as Figure 1 As shown, the gas-material mixing device also includes a discharge main pipe 6 and a second observation mirror 7. One end of the discharge main pipe 6 is connected to the other end of the diffuser pipe 5, and the other end of the discharge main pipe 6 is provided with a discharge port 8 for mixing and discharging. The second observation mirror 7 is disposed on the outer wall of the discharge main pipe 6.

[0036] The working principle of the above embodiment is as follows: When the gas-feed mixing device is working, the air inlet 11 receives power from the blower. The blower sends gas into the air inlet 11 through the gas power source pipeline connected to the front end of the main air inlet 9, and then from the air inlet 11 into the nozzle 10, and further into the main air inlet 9. Because the nozzle 10 has a large inlet size and a small outlet size, and the main air inlet 9 is larger than the outlet size of the nozzle 10, the gas will accelerate and flow at high speed after passing through the nozzle 10, forming a certain negative pressure vacuum in the main air inlet 9, providing power for the subsequent mixing of feed and gas.

[0037] Feed is received at the feed inlet 1 at the top of the feed hopper 2. The feed enters the feed hopper 2 under gravity, and then enters the air intake pipe 9 through the interface 4. The feed and gas are fully mixed in the air intake pipe 9 to form a high-pressure air-feed mixture. Both the interface 4 and the air intake pipe 9 are inclined to facilitate the falling of the feed.

[0038] The gas-material mixture is conveyed through the other end of the inlet pipe 9 to the diffuser pipe 5, then through the diffuser pipe 5 to the outlet pipe 6, and finally output through the outlet port 8 at the other end of the outlet pipe 6. The other end of the outlet pipe 6 is connected to subsequent conveying pipelines to facilitate the conveying of the gas-material mixture to the subsequent conveying pipelines.

[0039] This application can monitor the falling and blockage of the gas-material mixture in real time through the second observation mirror 7. If uneven gas-material mixing or pipeline blockage occurs, it can be detected and repaired immediately.

[0040] According to some embodiments, such as Figure 1 As shown, flanges are connected to the outer wall of one end of the air intake pipe 9, the outer wall of the top of the discharge hopper 2, and the outer wall of the other end of the discharge pipe 6.

[0041] Based on the above embodiments, one end of the air intake pipe 9 is connected to the front gas power source pipeline through a flange, the top of the discharge hopper 2 is connected to the front feed conveying pipeline through a flange, and the other end of the discharge pipe 6 is connected to the subsequent conveying pipeline through a flange.

[0042] According to some embodiments, the size of the inlet 1 is three times the size of the outlet 8.

[0043] Based on the above embodiments, in order to improve the feed conveying efficiency, the size of the feed inlet 1 can be designed to be as large as possible, so that more feed can be discharged. In some embodiments, the size of the feed inlet 1 is about 3 times the size of the discharge outlet 8.

[0044] Furthermore, in some embodiments, the length of the diffuser tube 5 is approximately half the length of the discharge main tube 6, and the outlet size of the diffuser tube 5 is approximately four-fifths of the inlet size of the diffuser tube 5.

[0045] Furthermore, in some embodiments, the inlet size of the nozzle 10 is approximately twice the outlet size of the nozzle 10, and the length of the nozzle 10 is approximately two-thirds the length of the intake manifold 9.

[0046] According to some embodiments, such as Figure 1 As shown, the main air intake pipe 9 forms a 60° angle with the left horizontal plane, the main air intake pipe 9 forms a 60° angle with the outlet direction of the interface 4, and the outlet direction of the interface 4 forms a 60° angle with the right horizontal plane. Both the interface 4 and the main air intake pipe 9 are inclined to facilitate the falling of feed.

[0047] According to some embodiments, the gas-feed mixing device is made of stainless steel, and its inner wall is smooth and flat. Firstly, the smooth inner wall reduces feed damage caused by collisions. Secondly, as the feed moves downwards under its own weight, it prevents feed residue from remaining on the inner wall and also reduces feed residue within the pipe during the mixing process.

[0048] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0049] Although this disclosure has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Because this disclosure can be embodied in many forms without departing from the spirit or substance of this application, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
