[0037] See also Figure 1-Figure 5 , a mixing device extrusion structure, comprising:

[0038] A mixing device 1, comprising a mixing machine and an extruder;

[0039] A guide member 2 is screwed to one side of the mixing device 1. The guide member 2 includes a guide cylinder 21. A hollow conical cylinder 22 is provided at both the upper and lower ends of the guide cylinder 21. The diameter of the opposite side of the hollow conical cylinder 22 is larger than the diameter of the guide cylinder 21. A connecting side block 23 is provided on the outer surface of the guide cylinder 21. A tight protrusion is provided inside the guide cylinder 21.

[0040] Based on the above, the mixer and the extruder are prior art. The mixer and the extruder here are only for the convenience of understanding the pre-cooling mechanism, so the specific structure and working principle of the mixer and the extruder are not described here in detail.

[0041] The setting of the guide cylinder 21 and the hollow conical cylinder 22 allows the extruded strip raw material to move along the direction of the guide 2 and extend into the interior of the cooling pool. The setting of the protrusion allows the air with small particles of water to enter normally, and the small particles of water collide with the protrusions to form larger water droplets that fall into the cooling pool.

[0042] like Figure 1-Figure 4 as well as Figure 6-Figure 8 As shown, the air cylinder 3 is set on the outer surface of the guide member 2 by screws and nuts, and includes a side opening 33 and a reinforcement member 34;

[0043] The ventilator 3 includes a hollow cylinder 31. The outer surface of the bottom end of the hollow cylinder 31 is provided with side openings 33. The side openings 33 are distributed in an annular shape and are equidistantly. A reinforcement 34 is provided inside the hollow cylinder 31. The reinforcement 34 is communicated with the hollow cylinder 31 and is provided above the side openings 33.

[0044] The upper surface of the hollow cylinder 31 is provided with a threaded through hole 35 , and the outer surface of the hollow cylinder 31 is provided with a connecting block 32 , and the connecting block 32 is provided between the reinforcement 34 and the threaded through hole 35 ;

[0045] An air suction member 4 is provided on the outside of the ventilator 3 and is in communication with the ventilator 3. The air suction member 4 includes an air suction pipe 41. The outer surface of the air suction pipe 41 is provided with an external thread 42. The external thread 42 matches the threaded through hole 35. A limit plate 43 is provided on the outer surface of the air suction pipe 41. The limit plate 43 is provided above the external thread 42 and has a diameter greater than the diameter of the threaded through hole 35.

[0046] A connecting cavity 44 is provided at the top end of the air intake pipe 41. The connecting cavity 44 and the air intake pipe 41 are in communication with each other. The air intake pipe 41 extends into the interior of the ventilator 3 and is located above the reinforcement 34. A connecting flange 45 is provided on the outer surface of the connecting cavity 44.

[0047] Based on the above, the ventilation cylinder 3 and the suction piece 4 are connected to each other through threads. At this time, the suction piece 4 and the ventilation cylinder 3 are connected to each other. The ventilation cylinder 3 is extended into the cooling pool when in use. The cooling water in the cooling pool enters from the inside of the side opening 33 and is immersed to the top of the reinforcement 34. When suction is generated above the suction pipe 41, the air pressure inside the ventilation cylinder 3 is reduced. Therefore, the air outside the ventilation cylinder 3 is pressed into the interior of the ventilation cylinder 3 from the side opening 33 under the action of the air pressure difference. At this time, the pressed air flow is in full contact with the cooling water, and contains a large number of small particles of water droplets inside.

[0048] like Figure 3 、 Figure 4 、 Figure 9 and Figure 10 As shown, the power mechanism 5 is arranged at the top of the air suction member 4 and extends to the interior of the ventilation cylinder 3, and includes a motor 52, a rotating shaft 53, a vent hole 54 and a first fan blade block 56;

[0049] The power mechanism 5 includes a connecting disk 51, the upper surface of which is provided with a first fan blade block 56. The diameter of the connecting disk 51 is equal to the diameter of the connecting flange 45. The connecting disk 51 and the connecting flange 45 are connected to each other by screws and nuts. A motor 52 is provided on the upper surface of the connecting disk 51. A rotating shaft 53 is provided at the output shaft of the motor 52. A vent hole 54 is provided on the outer surface of the rotating shaft 53. The vent hole 54 is provided inside the connecting cavity 44. A connecting prism 55 is provided at the bottom end of the rotating shaft 53. A threaded blind hole is provided at the bottom end of the connecting prism 55.

[0050] Based on the above, when the motor 52 is energized, the electric rotating shaft 53 rotates. When the rotating shaft 53 rotates, it drives the first fan blade block 56 to rotate, thereby allowing the air inside the suction part 4 to flow upward into the interior of the connecting pipe 6. The setting of the vent hole 54 allows air to enter the interior of the connecting pipe 6 from the interior of the suction part 4. The setting of the connecting prism 55 allows the second fan blade block 7 to be connected to the rotating shaft 53 by screws.

[0051] like Figure 1-Figure 3 As shown, a connecting pipe 6 is provided at the top of the power mechanism 5 by means of screws and nuts, and the other end extends to above the guide member 2. The connecting pipe 6 comprises a U-shaped connecting pipe, one end of which is provided with a flange, and the flange is connected to the air suction member 4 and the power mechanism 5 by means of screws and nuts. The other end of the connecting pipe 6 extends to directly above the guide member 2.

[0052] Based on the above, the connecting pipe 6 plays a role in guiding the airflow, so that the air inside the air suction member 4 can flow to just above the guide tube 21 , and the airflow can enter the interior of the guide tube 21 .

[0053] like Figure 3 、 Figure 4 as well as Figure 11 As shown, the second fan blade block 7 is set at the bottom end of the rotating shaft 53 by a screw, and the connecting pipe 6 includes a U-shaped connecting pipe;

[0054] The second blade block 7 includes a connecting sleeve 71. The upper surface of the connecting sleeve 71 is provided with a prismatic hole 72. The prismatic hole 72 matches the connecting prism 55. The outer surface of the connecting sleeve 71 is provided with a blade 73. The second blade block 7 is connected to the connecting prism 55 by screws. The second blade block 7 is located below the reinforcement member 34.

[0055] Based on the above, the setting of the prismatic hole 72 enables the second fan blade block 7 to be fixed to the outside of the rotating shaft 53 by screws. When the rotating shaft 53 rotates, it can drive the second fan blade block 7 to rotate together. The second fan blade block 7 here has the effect of stirring the cooling water, making it easier for the cooling water in the cooling pool to form small particles of water, and the small particles of water can flow with the airflow.

[0056] In actual use of this embodiment, by immersing the aerator cylinder 3 in the cooling pool, that is, cooling water enters the aerator cylinder 3 and immerses the reinforcement 34. At this time, the liquid level is located between the reinforcement 34 and the air suction member 4. The strip material extruded by the mixing device 1 extends along the direction of the guide cylinder 21 into the cooling pool;

[0057] The motor 52 is energized to drive the rotating shaft 53 to rotate. At this time, the first fan blade block 56 and the second fan blade block 7 rotate together. When the first fan blade block 56 rotates, the air inside the air intake member 4 and the ventilation cylinder 3 forms an airflow and is discharged from one end of the connecting pipe 6. The discharged airflow enters the interior of the guide cylinder 21. During this process, the internal air pressure of the ventilation cylinder 3 decreases. Since the atmospheric pressure is not constant, an air pressure difference is generated between the two. Under the action of the air pressure difference, the external air enters the interior of the ventilation cylinder 3 through the side opening 33.

[0058] During the above process, the air flow needs to flow through the cooling water, so the air flow contains more small particles of water. At the same time, the second fan blade block 7 has a stirring effect on the cooling water, making it easier for the air flow to enter. At the same time, there are more small particles of water inside the ventilation cylinder 3. The air flow with small particles of water flows along the ventilation cylinder 3, the air suction member 4, the air vent 54 and the connecting pipe 6 and then flows into the interior of the guide cylinder 21 again. On the one hand, the air flow with small particles of water contacts the strip material and can cool the strip material. On the other hand, the air flow with small particles of water can absorb pungent harmful gases. When the absorbed small particles of water contact with the protrusions, larger water droplets are formed and flow back into the cooling pool.

[0059] The extrusion structure is provided with a pre-cooling mechanism so that the strip material can be processed before being extended into the cooling pool, effectively reducing the occurrence of pungent gases generated by the material under high temperature conditions drifting into the air.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
