[0020] Example

[0021] Reference Figure 1-3, a vacuum exhaust device for a polymer plastic pipe extruder, comprising a support base 1 and a condensing mechanism, wherein a water storage tank 2, a purification tank 3 and a vacuum exhaust pump 4 are fixed to the top outer wall of the support base 1 in sequence;

[0022] Specifically, the condensing mechanism includes a condenser housing 5 fixedly connected to the top outer wall of the water storage tank 2, a serpentine condenser tube 6 fixedly passing through the condenser housing 5, a mounting plate 10 fixed to the rear outer upper outer wall of the water storage tank 2, and a water pump 11 fixed to the top outer wall of the mounting plate 10;

[0023] Furthermore, the water pumping end of the water pump 11 is connected to the water storage tank 2 through a water pumping pipe, and the water outlet end of the water pump 11 is fixedly connected to the top of the condenser housing 5 through a water delivery pipe 12, and a solenoid valve 13 is installed on the water pumping pipe;

[0024] Furthermore, the bottom of the condenser housing 5 is connected to the water storage tank 2 through a return pipe 14, and a filling pipe 15 is fixedly connected to the front of the water storage tank 2, and a sealing screw cap is screwed on the filling pipe 15;

[0025] Furthermore, one side of the purification box 3 is connected to one end of the serpentine condenser tube 6, and the other side of the purification box 3 is connected to the exhaust end of the vacuum exhaust pump 4;

[0026] Furthermore, the connection between the serpentine condenser tube 6 and the condenser housing 5, the connection between the water supply pipe 12 and the condenser housing 5, and the connection between the return pipe 14 and the condenser housing 5 are all sealed connections;

[0027] Furthermore, a purification assembly is provided in the purification box 3, and the purification assembly includes a filter screen 7 and an activated carbon filter screen 8 which are sequentially inserted into the purification box 3, and a sealing plate 9 which is sealed and fixed to the front outer wall of the purification box 3;

[0028] In the specific embodiment of this embodiment: first, the front end of the serpentine condenser tube 6 is connected to the exhaust end of the polymer plastic pipe extruder, and then the water pump 11, the vacuum exhaust pump 4 and the solenoid valve 13 are started;

[0029] Secondly, the discharged high-temperature gas will flow into the serpentine condenser tube 6. At this time, the water pump 11 draws out the cooling water in the water storage tank 2 through the water pumping pipe and sends it into the condenser shell 5 through the water delivery pipe 12 to fully cool the high-temperature gas flowing in the serpentine condenser tube 6. Then, the cooling water in the condenser shell 5 will flow back to the water storage tank 2 through the return pipe 14 to realize the recycling of water resources.
