[0020] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0021] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present application and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present application.

[0022] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0023] The water gun for carbon black granulation is mainly used to spray powdered carbon black into granulation water mixed with a binder to mix with it to form carbon black pellets. This process lays the foundation for the subsequent drying, screening, purification and packaging of carbon black products. The water gun plays a key role in this process. By directional injection of high-speed water flow, it helps mix the powdered carbon black with the binder to form the required carbon black pellets.

[0024] like Figure 1-2 As shown, a novel combined device for using a water gun for carbon black pelletizing includes a gun head 1 with a fan-shaped opening 3, a first fluid channel 4, a step 5, and a gun head seat 6. The fan-shaped opening 3 and the step 5 are located at the front end of the gun head 1, and the gun head seat 6 is located at the rear end of the gun head 1. The fan-shaped opening 3 is used as the fluid outlet, which increases the outlet angle of the gun head and the atomized area of ​​the carbon black when atomizing the carbon black.

[0025] The gun head 1 is connected to a gun head connector 2 , which is arranged at the rear end of the gun head 1 and fixedly connected to the step 5 . The gun head connector 2 is provided with a second fluid channel 7 , which is connected to the first fluid channel 4 .

[0026] The second fluid channel 7 adopts a Venturi structure, which can significantly improve the fluid delivery efficiency of the water gun, and has a simple, reliable structure and is easy to maintain. The Venturi structure is provided with a contraction section 8, a throat 9 and a diffusion section 10, which are connected in sequence. The maximum diameter of the contraction section 8 is set to D1, the diameter of the throat 9 is set to D2, and the maximum diameter of the diffusion section 10 is set to D3. The diameter of the contraction section 8 is larger than the diameter of the throat 9, and the diameter of the throat 9 is smaller than the maximum diameter of the diffusion section 10. D1>D3>D2. The diameter ratios of the contraction section 8, throat 9 and diffusion section 10 are D1:D2:D3, which is 2:1:1.5 respectively.

[0027] In order to reduce fluid energy consumption, the diameter of the first fluid channel 4 is equal to the maximum diameter D3 of the diffuser section 10 .

[0028] Because the gun head is in contact with fluid during daily work, the gun head 1 and the gun head connector 2 are made of 304 material, which is resistant to high temperature and corrosion.

[0029] During normal use, the fluid first flows through the second fluid channel 7, and then obtains high-speed fluid. The high-speed fluid passes through the first fluid channel 4, is expanded by the fan-shaped mouth 3, and is then sprayed onto the carbon black, further improving the quality of carbon black granulation and greatly improving work efficiency.

[0030] The above describes the implementation methods of the present application in detail in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application.
