Description

Technical Field

[0001] The utility model relates to the technical field of acetylene black preparation, in particular to a mixing device for an acetylene black production line. Background Technique

[0002] The traditional production method of acetylene black is to first produce acetylene by reacting calcium carbide with water, and then pyrolyze acetylene to produce carbon black. However, the yield of producing acetylene black using calcium carbide is relatively low, resulting in a high cost for the method of producing carbon black using calcium carbide;

[0003] The Chinese patent document (CN115181434A) discloses a process method and device for preparing carbon black by mixing benzene and acetylene. Acetylene gas and gas monocyclic aromatic hydrocarbon are used as raw materials for carbon black preparation. This process replaces a part of acetylene gas with gas monocyclic aromatic hydrocarbon to realize the production of carbon black, reducing the production cost of carbon black. However, how to better mix benzene gas and acetylene gas is still a problem to be solved at present, because it affects the quality of the prepared carbon black. Summary of the Utility Model

[0004] In order to solve the problem that the existing acetylene black production device cannot mix benzene gas and acetylene gas well; the purpose of the utility model is to provide a mixing device for an acetylene black production line.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: A mixing device for an acetylene black production line, including a cylinder body, an air inlet hole is penetrated and opened on the upper part of the cylinder body, an acetylene gas inlet pipe is fixedly arranged on the surface of the cylinder body, an acetylene gas inlet is penetrated and opened at one end of the acetylene gas inlet pipe away from the cylinder body, the acetylene gas inlet is communicated with the air inlet hole, a through hole is penetrated on the acetylene gas inlet pipe, a benzene gas inlet pipe is fixedly arranged in the through hole, a benzene gas inlet is penetrated and opened at one end of the benzene gas inlet pipe away from the acetylene gas inlet pipe, and the benzene gas inlet is communicated with the acetylene gas inlet pipe.

[0006] Preferably, a positioning block is fixedly arranged on the inner wall of the cylinder body, a positioning rod is fixedly arranged in the positioning block, a plurality of baffle plates are fixedly arranged on the positioning rod at equal intervals, a flow deflection channel is formed between two adjacent baffle plates, and the baffle plates divide the inner part of the cylinder body into a first cavity and a second cavity which are communicated with each other.

[0007] Compared with the prior art, the beneficial effect of the utility model lies in:

[0008] 1. By setting up a cylinder body, air inlet holes, acetylene gas inlet pipes, acetylene gas inlets, through holes, benzene gas inlet pipes, benzene gas inlets, positioning blocks, positioning rods, baffle plates, flow deflection channels, a first cavity, and a second cavity, the acetylene gas and benzene gas can be preliminarily mixed in the acetylene gas inlet pipe. Subsequently, when the preliminarily mixed gas passes through the flow deflection channel, due to inertia, it will collide on the bent surface of the baffle plate to form a turbulent flow, thereby further mixing the gas evenly. This solves the problem that the existing acetylene black production device cannot mix benzene gas and acetylene gas well, and prevents the poor quality of the prepared carbon black caused by uneven mixing of benzene gas and acetylene gas.

[0009] 2. Through the mutual cooperation between the rotating rod, rotating block, fan blades, fixed plate and the motor, the fan blades can generate wind force. When passing through the wind force, the preliminarily mixed gas collides with the bent surface of the baffle plate at a faster speed, generating a stronger turbulent flow and making the gas mix more evenly.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0017] Embodiment: As Figures 1-4 shown, the present utility model provides a mixing device for an acetylene carbon black production line, which includes a cylinder body 1. An air inlet hole 11 is penetrated and opened on the upper part of the cylinder body 1. An acetylene gas inlet pipe 12 is fixedly arranged on the surface of the cylinder body 1. An acetylene gas inlet 13 is penetrated and opened at one end of the acetylene gas inlet pipe 12 away from the cylinder body 1. The acetylene gas inlet 13 communicates with the air inlet hole 11. A through hole 14 is penetrated and opened on the acetylene gas inlet pipe 12. A benzene gas inlet pipe 15 is fixedly arranged in the through hole 14. A benzene gas inlet 16 is penetrated and opened at one end of the benzene gas inlet pipe 15 away from the acetylene gas inlet pipe 12. The benzene gas inlet 16 communicates with the acetylene gas inlet pipe 12.

[0018] A positioning block 2 is fixedly arranged on the inner wall of the cylinder body 1. A positioning rod 21 is fixedly arranged in the positioning block 2. A plurality of baffle plates 22 are fixedly arranged on the positioning rod 21 at equal intervals. A baffle channel 23 is formed between two adjacent baffle plates 22. When the preliminarily mixed gas flows from the first cavity 24 to the second cavity 25, it will pass through the baffle channel 23. At this time, when the gas passes through the baffle channel 23 at a certain speed, due to the action of inertia, it will collide on the bending surface of the baffle plate 22 to form a turbulent flow, so as to further mix the gas evenly.

[0019] The baffle plate 22 divides the interior of the cylinder body 1 into a first cavity 24 and a second cavity 25 that are connected and communicated. Separating the space inside the cylinder body 1 is conducive to further mixing the gas evenly subsequently.

[0020] A positioning hole 3 is penetrated and opened at one end of the cylinder body 1 close to the first cavity 24. A connecting block 31 is fixedly arranged in the positioning hole 3. A first connecting hole 32 is penetrated and opened on the connecting block 31. A fixing block 33 is fixedly arranged at one end of the connecting block 31 close to the first cavity 24. A second connecting hole 34 that communicates with the first connecting hole 32 is penetrated and opened on the fixing block 33. The positioning hole 3 can be sealed through the connecting block 31 and the fixing block 33 to prevent the internal gas from leaking.

[0021] A rotating rod 35 is rotatably arranged in the second connecting hole 34. One end of the rotating rod 35 away from the second connecting hole 34 is fixedly provided with a rotating block 36, and a plurality of equally spaced fan blades 37 are fixedly arranged on the rotating block 36. The preliminarily mixed gas can be blown from the first cavity 24 to the second cavity 25 through the rotating block 36 and the fan blades 37, so that the preliminarily mixed gas passes through the baffle channel 23 at a certain speed and is mixed more evenly.

[0022] One end of the cylinder body 1 close to the first cavity 24 is fixedly provided with symmetrically distributed fixing plates 4. A motor 41 is fixedly arranged between the two fixing plates 4. One end of the rotating rod 35 away from the rotating block 36 is fixedly arranged at the end of the output shaft of the motor 41. One end of the connecting block 31 away from the fixed block 33 is fixedly arranged on the motor 41. The rotating rod 35 can be driven by the motor 41, and then the fan blades 37 rotate to generate wind power.

[0023] One end of the cylinder body 1 away from the motor 41 is fixedly provided with a mixed gas outlet pipe 42. The end of the mixed gas outlet pipe 42 away from the cylinder body 1 is provided with a mixed gas outlet 43 communicating with the second cavity 25. The mixed gas formed by the uniform mixing of benzene gas and acetylene gas can be discharged through the mixed gas outlet 43.

[0024] Symmetrically distributed feet 44 are fixedly arranged on the outer surface of the cylinder body 1. The symmetrically distributed feet 44 can increase the stability of the device.

[0025] Working principle: When in use, the staff needs to first connect the acetylene gas cylinder to the acetylene gas inlet 13 and the benzene gas cylinder to the benzene gas inlet 16, and then inject the acetylene gas and the benzene gas into the acetylene gas inlet pipe 12 and the benzene gas inlet pipe 15. Since through holes 14 are formed in the acetylene gas inlet pipe 12, the benzene gas inlet pipe 15 is fixedly arranged in the through holes 14, and the benzene gas inlet 16 communicates with the acetylene gas inlet pipe 12, when the acetylene gas and the benzene gas are injected, they will be preliminarily mixed in the acetylene gas inlet pipe 12 to form a mixed gas, and then the mixed gas will enter the inside of the cylinder body 1 through the intake holes 11. As the mixed gas enters the first cavity 24, the motor 41 is started. Since the end of the output shaft of the motor 41 is fixed to the rotating rod 35, one end of the rotating rod 35 away from the motor 41 is fixedly provided with a rotating block 36, and a plurality of equally spaced fan blades 37 are fixedly arranged on the rotating block 36. When the motor 41 is started, the fan blades 37 will be driven to rotate. As the fan blades 37 rotate, wind power will be generated. The preliminarily mixed gas in the first cavity 24 will flow from the first cavity 24 to the second cavity 25 under the action of the wind power, and will pass through the baffle channel 23 on the way. When the gas passes through the baffle channel 23 at a certain speed, due to inertia, it will collide on the bending surface of the baffle 22 to form a turbulent flow, so that the gas is further mixed evenly, and then the evenly mixed gas will be discharged through the mixed gas outlet pipe 42.

[0026] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
