[0025] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0028] Example 1

[0029] This embodiment proposes a closed-loop induced material receiving device; please refer to [link / reference]. Figures 1-6 The closed-loop induced feeder includes a pipe with a bend. Specifically, the pipe includes a first pipe 1, a second pipe 2 forming a bend with the first pipe 1, and a third pipe 3 communicating with the second pipe 2. The material outlet is in the first pipe 1, the material inlet is in the second pipe 2, and the air inlet is in the third pipe 3. In this embodiment, air with a flow rate enters the third pipe 3 through the air inlet, and material enters the second pipe 2 through the material inlet. During this process, the air with a flow rate enters the second pipe 2 from the third pipe 3 and mixes with the material to form a stable gas-solid two-phase flow. Further, the material outlet is connected to a vertical lift pipe (not shown in the attached figures). After connection, the gas-solid two-phase flow from the closed-loop induced feeder will enter the vertical lift pipe with a certain initial velocity.

[0030] Please see Figure 6 There is a drain outlet 11 at the corner, the edge of the drain outlet 11 is flush, and the drain outlet 11 is also equipped with a valve 4, which is connected to the drain outlet 11. Figure 3 The two hinges 7 shown are connected to the second tube 2. After connection, the valve 4 can completely cover the drain port 11 within the rotation range provided by the hinges 7. This design means that the valve 4 can either block the drain port 11 or rotate away from it, exposing the drain port 11 to the outside. Please refer to [link to relevant documentation]. Figure 6 The valve 4 has a folded edge, and a sealing gasket 9 is adhered to the folded edge and corner. When the valve 4 blocks the drain port 11, the sealing gasket 9 fills the gap between the drain port 11 and the valve 4, ensuring that the pipeline is isolated from the external environment.

[0031] Please see Figure 6An arc-shaped first baffle 6 is fixed inside the valve 4 (preferably with a detachable fixing method for easy replacement later). After the valve 4 blocks the discharge port 11, the first baffle 6 can act as a springboard to propel the gas-solid two-phase flow formed by the material and air to the first pipe 1 until the outlet position. Compared with the traditional induced feeder, the first baffle 6 is a consumable component, fixed at the valve 4. This facilitates maintenance and allows it to work with the valve 4 to quickly release material blocked at the bend.

[0032] Please see Figure 3 and Figure 6 While valve 4 can block drain outlet 11, it still requires fasteners for support. Specifically, the fasteners are latch 5 and lug 8, such as... Figure 6 As shown, the latch 5 is installed on the first pipe 1, and the lug 8 is installed on the folded edge of the valve 4. The latch 5 and the lug 8 are a modular structure. When assembled, the valve 4 is fastened to the drain port 11. Of course, the latch 5 and the lug 8 can also be separated after assembly (separation usually occurs during maintenance and unloading). When separated, the valve 4 will quickly rotate downward under its own weight, exposing the drain port 11 to the outside.

[0033] Please see Figure 6 The sealed induced feeder proposed in this embodiment also has other ingenious designs. Specifically, a second baffle 10 is provided on the upper edge of the drain port 11, that is, at the location of the hinge 7. The second baffle 10 is preferably a flat plate. To further explain, the second baffle 10 extends toward the area where the drain port 11 is located. After the extension, when the valve 4 blocks the drain port 11, the mixture of material and air will pass through the connection between the valve 4 and the first pipe 1, thereby preventing the mixture from overflowing from the connection.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
