Detailed Description

The present application is described in further detail below with reference to the attached drawings.

The embodiment of the application discloses a vacuum cooling water tank of a plastic extruder. Referring to fig. 1, the vacuum cooling water tank includes a frame 1, a cooling tank 2 mounted on the frame 1, and a vacuum cooling box 3 mounted on one side of the cooling tank 2.

Referring to fig. 1, a vacuum cooling tank 3 is located on the side of the frame 1 near the plastic extruder. Two cooling cavities are arranged in the vacuum cooling box 3, and two plastic pipes 10 can be simultaneously cooled in vacuum. The vacuum cooling box 3 is provided with a pipeline inlet and a pipeline outlet at two ends of the cooling cavity respectively. The cooling tank 2 is integrally connected to the side of the vacuum cooling tank 3 remote from the extruder. An outlet end is arranged at one end of the cooling tank 2 far away from the outlet of the pipeline.

Referring to fig. 1 and 2, spray water pumps 4 are installed at the bottom of the frame 1 in one-to-one correspondence to the cooling chambers. The bottom of the two vacuum cooling tanks 3 is connected with a water collecting tank 31, and the water collecting tank 31 can be connected with an external water source. The spray water pump 4 communicates with the water collection tank 31. A spray assembly 5 is arranged in the cooling cavity. The showerhead assembly 5 includes a showerhead 51 and a showerhead 52 mounted on the showerhead 51. The spray pipes 51 are distributed along the circumferential direction of the inner wall of the cooling box at intervals, and the spray pipes 51 are communicated with the spray water pump 4 through pipelines. After the spray water pump 4 supplies water to the spray pipe 51, the spray head 52 sprays and cools the plastic pipe 10, and a large amount of water flow is discharged into the water collecting tank 31 from the cooling cavity for recycling.

Referring to fig. 1, vacuum pumps 6 are installed at the bottom of the housing 1 in one-to-one correspondence to the cooling chambers. The vacuum pump 6 is communicated with the cooling cavity through a pipeline. After the vacuum pump 6 vacuumizes the cooling cavity, the air pressure in the cooling cavity is reduced, so that the boiling point of water is reduced, water drops attached to the plastic pipe 10 can be quickly vaporized, and the plastic pipe 10 is quickly cooled.

Referring to fig. 1, a cooling water pump 7 is also installed at the bottom of the frame 1. The cooling water pump 7 is communicated with the bottom of the cooling tank 2. An overflow pipe 21 is inserted and fixed into the cooling tank 2. The upper end of the overflow pipe 21 is higher than the plastic pipe 10, so that the water in the cooling tank 2 can overflow the plastic pipe 10, thereby sufficiently cooling the plastic pipe 10.

Referring to fig. 1 and 3, the pipe inlet, the pipe outlet, and the outlet end are each fixed with a seal disk 8 by bolts. The middle part of the sealing disc 8 is provided with a through hole 81 for the barrel plastic pipe 10 to pass through. The inner wall of the through hole 81 is embedded with two sealing rings 82, and the two sealing rings 82 are distributed at intervals along the axis of the through hole 81. A rounded corner 83 is provided at the inner edge of the aperture of the through hole 81. In this way, when the plastic pipe 10 passes through the seal disk 8, abrasion of the outer wall of the plastic pipe 10 can be reduced, and the sealability between the plastic pipe 10 and the seal disk 8 can be improved.

Referring to fig. 1, further, to enhance the cooling effect on the plastic tube 10. The cooling water pump 7 is connected with a shower pipe 9, and a switch valve can be arranged on the shower pipe 9. Before plastic tubing 10 gets into inside the vacuum cooling case 3, through drenching pipe 9 to the preliminary cooling of plastic tubing 10 outer wall for the setting can be hardened fast to the plastic tubing 10 outer wall.

Referring to fig. 1, a receiving groove 11 is welded on the outer wall of the vacuum cooling tank 3 below the pipeline inlet for receiving water sprayed by the shower pipe 9, and the bottom of the receiving groove 11 discharges the water through a water pipe. Since the water in the cooling bath 2 overflows the plastic pipe 10, part of the water may seep between the seal disk 8 and the plastic pipe 10. Therefore, the cooling tank 2 is also provided with a receiving tank 11 below the outlet end. The water discharged from the two receiving tanks 11 can be treated in a centralized way and recycled.

The implementation principle of the vacuum cooling water tank of the plastic extruder in the embodiment of the application is as follows:

after the plastic pipe 10 extruded from the plastic extruder enters the shower pipe 9 for primary cooling, the plastic pipe enters the vacuum cooling box 3, the spray head 52 sprays the periphery of the plastic pipe 10, and the vacuum pump 6 performs vacuum pumping treatment on the cooling cavity, so that water drops attached to the plastic pipe 10 are quickly vaporized, and the plastic pipe 10 is quickly cooled. Subsequently, the plastic pipe 10 enters the cooling tank 2, and water is supplied to the cooling tank 2 by the cooling water pump 7, so that the water flow in the cooling tank 2 is in a flowing state, and the plastic pipe 10 is sufficiently cooled. The plastic tube 10 is threaded out of the outlet end and then enters the next process.
