DETAILED DESCRIPTION

[0018] Reference Figure 1-4 A circulating water cooling mechanism for polyethylene extrusion granulation comprises a bracket 1 and a fixed plate 2, the fixed plate 2 is connected to a chassis 3, the chassis 3 is connected to a heat dissipation component 4, the heat dissipation component 4 comprises a fixed heat dissipation component 41 and a circulating water cooling component 42, the top of the chassis 3 is connected to a feed hopper 5, and the chassis 3 is connected to an overheating alarm mechanism 6.

[0019] The fixed heat dissipation component 41 includes two fixed rings 411, which are respectively fixed to the upper and lower sides of the chassis 3 by multiple bolts. The two fixed rings 411 are commonly connected to multiple heat dissipation fins 412, and the multiple heat dissipation fins 412 are arranged in a ring array with the central axis of the chassis 3 as the axis. The circulating water cooling component 42 includes a spiral tube 421, which is sleeved on the outside of the chassis 3 and passes through the multiple heat dissipation fins 412 at the same time. The bottom of the spiral tube 421 is connected to a liquid inlet pipe 422. The liquid inlet pipe 422 is fixed on the fixed plate 2, and the liquid inlet pipe 422 is connected to the water pump. The cooling water is input into the liquid inlet pipe 422 through the water pump and enters the spiral tube 421 to achieve the effect of spiral movement of the cooling water, which can improve the cooling effect. When the water pump ends its work, under the action of gravity, the cooling water returns to the liquid inlet pipe 422 along the spiral tube 421, so that the cooling water continues to be transported to the spiral tube 421 after the next work of the water pump. The spiral tube 421 adopts a corrugated tube structure.

[0020] The overheat alarm mechanism 6 includes a plurality of connecting frames 61 connected to the top of the chassis 3, and the plurality of connecting frames 61 are commonly connected to a connecting ring 62, and a plurality of push rods 63 are abutted against each other at the bottom of the connecting ring 62. A push rod 63 is inserted at the top of each heat dissipation fin 412, and the push rod 63 is made of a metal copper material with a high thermal expansion coefficient. When the temperature of the chassis 3 is high, the push rod 63 will expand, and the push rod 63 will exert pressure on the connecting ring 62. The higher the temperature, the greater the pressure. The bottom of the connecting ring 62 is connected to a conductive ring of piezoelectric material, and the connecting ring 62 is electrically connected to an alarm. When the connecting ring 62 is subjected to a large pressure, the alarm will work. The number of heat dissipation fins 412 is not less than eight, and the number of connecting frames 61 is not less than four.

[0021] When the utility model is in use, the raw materials are conveyed to the chassis 3 through the feed hopper 5 for granulation. In this process, the fixed heat dissipation component 41 located outside the chassis 3 realizes the heat dissipation of the chassis 3, wherein the multiple heat dissipation fins 412 in the fixed heat dissipation component 41 increase the heat dissipation area between the chassis 3 and the outside, and the two fixing rings 411 play the role of assembling and fixing the fixed heat dissipation component 41 and the chassis 3 to each other, wherein the heat dissipation fins 412 can also be made of hollow metal materials, thereby improving their own heat dissipation speed, further improving the heat dissipation efficiency of the chassis 3, and the fixed heat dissipation component 41 The connected circulating water cooling component 42 includes a spiral tube 421 and a liquid inlet pipe 422, wherein the liquid inlet pipe 422 is connected to an external water pump. When the heat dissipation speed of the fixed heat dissipation component 41 is insufficient, the cooling water can be input into the spiral tube 421 through the water pump. The contact area and speed of the cooling water on the fixed heat dissipation component 41 are increased by the design of the spiral line of the spiral tube 421, and the water pressure of the water pump can be released after the cooling water reaches the top of the spiral tube 421, so that the cooling water returns to the liquid inlet pipe 422, and then continues to be transported by the water pump to achieve the effect of circulating water cooling and improve the cooling speed of the chassis 3.

Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive.
