[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0022] like Figures 1-3 As shown, one embodiment of this application provides a reaction vessel feeding anti-splash device, including a feeding hopper 1. The lower end of the feeding hopper 1 is connected to a material guide pipe 2. The material guide pipe 2 has a bend at the discharge port at its lower end. The material guide pipe 2 is used to extend into the reaction vessel to guide the material to be fed along the path set in the pipe. An air nozzle 5 is installed on the bend to push and press the material along the material guide pipe 2 toward the discharge port. An air pipe 4 connected to the air nozzle 5 is fixed downward along the outer wall of the feeding hopper 1 and the material guide pipe 2.

[0023] In use, the material guide pipe 2 is inserted into the reactor. Material is added to the feeding hopper 1 and then flows along the side wall of the feeding hopper 1 into the material guide pipe 2. The material slowly enters the reactor along the path guided by the material guide pipe 2, avoiding direct impact on the bottom or side walls and preventing splashing. The upper end of the gas pipe 4 is connected to a gas cylinder or gas pump. Simultaneously with material addition, inert gas at an appropriate flow rate is injected through the gas pipe 4 via the gas nozzle 5 into the bend at the lower end of the material guide pipe 2. The airflow formed by the inert gas propels the material at the outlet and presses the material discharged from the outlet of the material guide pipe 2 towards the bottom of the reactor, preventing it from flying or splashing.

[0024] In this embodiment, when the material guide pipe 2 extends into the reactor, it faces downwards towards the center of the reactor. When the material is added to the reactor, it is first added into the feeding hopper 1. The buffering effect of the material guide pipe 2 allows the material to slowly enter the reactor along the set guide path, avoiding direct impact on the bottom of the reactor or splashing backwards from the side wall. During the material addition process, an inert gas with an appropriate flow rate is injected into the bend of the material guide pipe 2 through the gas pipe 4. This helps to propel the material in the bend of the material guide pipe 2 and press down the material falling from the outlet, preventing the material from accumulating in the bend and reducing splashing after discharge.

[0025] In one possible implementation, at least one buffer device 3 is installed inside the material guide tube 2 to absorb the impact force when the material falls.

[0026] The buffer device 3 is a mesh structure, porous material or elastic material, which is adapted to the physical properties of the material such as density, hardness, particle size, etc., to absorb the impact force when different materials such as powder, granules or liquid fall.

[0027] As Figures 4-6 shown in a possible implementation, the buffering device 3 is in sliding connection with the vertical section of the material guiding pipe 2, the upper end of the feeding hopper 1 is fixed with a top plate 7 with an opening on one side, the vertical pole 8 is vertically inserted into the top plate 7 and in sliding connection with the top plate 7, the lower end of the vertical pole 8 is fixed with the buffering device 3, and the upper end is fixed with the pressing plate 9, and the spring 10 is fixed between the pressing plate 9 and the top plate 7.

[0028] Pressing the pressing plate 9 can drive the buffering device 3 downward through the vertical pole 8, and after being released, the spring can drive the pressing plate 9 upward, move the buffering device 3 up and down along the vertical section of the material guiding pipe 2 and generate vibration, which is used for dredging and shaking off residual materials.

[0029] In a possible implementation, the upper end of the air pipe 4 is provided with an adjusting valve 6 for adjusting the air flow.

[0030] The flow and flow rate of the inert gas in the air pipe 4 can be controlled by twisting the knob of the adjusting valve 6.

[0031] As Figure 4 shown in a possible implementation, the bending part of the material guiding pipe 2 is made of flexible material with smooth inner wall, the outer wall of the bending part of the material guiding pipe 2 is sleeved and fixed with the shaped hose 11, and the air pipe 4 is a hose.

[0032] The smooth inner wall of the bending part of the material guiding pipe 2 can make the material fall and discharge smoothly, the flexible material can be bent along any path according to the needs of guiding the material, and the bending part can be shaped by sleeving and fixing the shaped hose 11, which is convenient to use.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that; it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
