Technical Field

[0001] This utility model relates to the field of modified plastics processing technology, and in particular to a modified plastics cooling device. Background Technology

[0002] Modified plastics refer to plastic products that have been processed through methods such as filling, blending, and reinforcement on the basis of general-purpose plastics and engineering plastics, thereby improving their properties such as flame retardancy, strength, impact resistance, and toughness.

[0003] In the production of modified plastics, plastic particles are often at a high temperature after extrusion molding, which makes them prone to sticking together. Therefore, a cooling device is needed to cool them down.

[0004] In the prior art, modified plastics are often cooled by water cooling, that is, the modified plastic to be cooled is placed in cooling water. However, because the temperature of the modified plastic is high before cooling, some of the modified plastic surfaces have already become sticky. If it is only placed in cooling water for cooling (such as the patent with application number CN202323030584.0) without stirring, it is difficult to separate the sticky modified plastic, resulting in poor cooling effect and affecting the cooling effect.

Further, as shown in Figure 1 and Figure 4 , the connection device comprises a connection plate 6 arranged on the opposite side walls of the placing frame 2 and a placing groove 7 arranged at the top end of the cooling pool 1 and used for placing the connection plate 6. Further, as shown in Figure 1 , the support frame 3 is L-shaped, and the support frame 3 is arranged at the top end of one side wall of the cooling pool 1 which is not provided with the placing groove 7. Compared with arranging the support frame 3 as an inverted U-shaped, the present utility model arranges the support frame 3 as L-shaped, which only occupies one side wall of the cooling pool 1, can reduce the shielding of the cooling pool 1, and is conducive to the operation of the staff beside the cooling pool 1. Further, as shown in Figures 1-2As shown, the stirring assembly comprises a first motor 8 arranged at the telescopic end of the hydraulic rod 4, a first rotating shaft 9 arranged at the bottom end of the first motor 8, and a plurality of first stirring rods 10 arranged at the outer wall of the first rotating shaft 9; the cover plate 5 is arranged at the bottom wall of the first motor 8.

[0027] Working principle: the modified plastic particles extruded from the extruder are contained in the placing frame 2, then the placing frame 2 is placed in the cooling pool 1, and the placing frame 2 is placed in the cooling pool 1, wherein, when the placing frame 2 is placed in the cooling pool 1, as shown in Figure 4 two connecting plates 6 need to be placed in two placing grooves 7. It is worth noting that before placing the placing frame 2 in the cooling pool 1, the cooling liquid needs to be pre-pumped into the cooling pool 1 through the liquid inlet pipe. Then, start the hydraulic rod 4 to make the stirring assembly move down until the cover plate 5 covers the top end of the placing frame 2 (as shown in Figure 3 then start the first motor 8, under the action of the first motor 8, make the first rotating shaft 9 drive the first stirring rod 10 to stir, which can accelerate the contact between the modified plastic particles and the cooling liquid, improve the cooling efficiency, and at the same time, can make the particles that are bonded or bunched to be scattered, to ensure that the particles are in a separated state. In actual implementation, semiconductor refrigerating fins (prior art, not shown in the figure) can also be installed on the side wall of the cooling box pool. After the temperature of the cooling liquid rises, the water pump on the liquid outlet pipe is opened to pump out the cooling liquid through the liquid outlet pipe, and the water pump on the liquid inlet pipe is opened to pump the cooling liquid contained in the liquid tank into the cooling pool 1 through the liquid inlet pipe, to continuously modify the modified plastic particles. After cooling is completed, the stirring assembly is moved up, and the placing frame 2 is taken out from the cooling pool 1.

During the cooling process, the second motor 14 is turned on to drive the second rotating shaft 15 to rotate the second stirring rod 16, thereby improving the flowability of the cooling liquid in the cooling pool 1 and improving the cooling effect. In particular, on the basis of the semiconductor refrigeration sheet, the temperature uniformity of the cooling liquid can be further improved, and the cooling effect can be improved. Further, as shown, Figures 1-4 The top end of each connecting plate 6 is provided with a handle 17 to facilitate the workers to carry the placing frame 2 into or out of the cooling pool 1, thereby improving the carrying convenience.
