The temperature of PVC during extrusion is relatively high, and water cooling is usually used to cool the PVC pipes by spraying water onto the pipe wall. However, some of the sprayed water will adhere to the surface of the pipe. In subsequent processing, the pipes need to be dried, such as for subsequent marking on the pipe surface. This greatly affects the production efficiency of the pipes and increases the time spent on secondary processing. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides a technical solution:

[0024] A water tank for PVC plastic pipe production includes a tank body 2 and an acrylic cover plate 1 screwed onto the tank body 2. A partition plate 7 is screwed and fixed inside the tank body 2. Sealing rings are fixed between the partition plate 7 and the tank body 2. The interior of the tank body 2 is divided into a first cooling chamber 9 and a second cooling chamber 10 by the partition plate 7. The areas of the first cooling chamber 9 and the second cooling chamber 10 can be changed according to the installation position of the partition plate 7 in the tank body 2, allowing for the replacement of corresponding spiral water spray pipes 8. The cooling water temperature sprayed by the spiral water spray pipes 8 in the first cooling chamber 9 is 35℃-45℃, and the cooling water temperature sprayed by the spiral water spray pipes 8 in the second cooling chamber 10 is... The temperature is between 18℃ and 22℃. By cooling the pipe body 3 with two cooling waters of different temperatures, the pipe body 3 can be gradually cooled and shaped. Compared with the traditional method of directly spraying low temperature cooling water, this method can reduce the damage caused by the rapid temperature change of the pipe body 3 material. The two sides of the water tank body 2 are provided with corresponding slots. Through-hole pipe 1 4 and through-hole pipe 2 11 are fixedly connected in the slots. The surface of the partition plate 7 is also provided with slots corresponding to through-hole 1 and through-hole 2. The pipe body 3 is movably connected in through-hole pipe 1 4, slots on the partition plate 7 and through-hole pipe 2 11. The pipe body 3 located in the first cooling chamber 9 and the second cooling chamber 10 is sleeved with a spiral water spray pipe 8. Several spray holes are provided on the inner side of the spiral water spray pipe 8.

[0025] The inside of the second through-tube 11 is fixedly connected to scraper 12 and scraper 2 13 respectively.

[0026] Specifically, water pumps 5 are screwed and fixed to the front end face of the water tank body 2 at the corresponding positions of the first cooling chamber 9 and the second cooling chamber 10.

[0027] Specifically, the rear end face of the water tank body 2 is fixedly connected to the corresponding positions of the first cooling chamber 9 and the second cooling chamber 10 with pipe joints 6. One end of the spiral water spray pipe 8 is fixedly connected to the partition plate 7 by screws. One end of the spiral water spray pipe 8 extends to the bottom of the water tank body 2, and the other end is connected to the water supply end of the water pump 5. The water pump 5's pumping end is connected to the inside of the treatment tank.

[0028] Specifically, the number of scraper blades 12 and 13 is at least three sets of annularly distributed on the inner wall of the through-tube 11. The scraper blades 12 and 13 are made of hard rubber material, and the three scraper blades 12 and 13 form a conical structure. A drainage hole 14 is opened on the lower side of the outer surface of the through-tube 11 between the scraper blades 12 and 13.

[0029] Working principle:

[0030] During operation, the main pipe 3 enters the water tank body 2 through the through-pipe 4, passes through the first cooling chamber 9 and the spiral spray pipe 8, then extends through the slots on the partition 7 to the second cooling chamber 10 and the spiral spray pipe 8, and finally extends out of the water tank body 2 through the through-pipe 11. As the main pipe 3 passes through the first cooling chamber 9 and the second cooling chamber 10, the corresponding water pump 5 draws and delivers the cooling water from the cooling chambers to the spiral spray pipe 8. The water is then evenly sprayed onto the surface of the main pipe 3 through the spray holes in the spiral spray pipe 8, thus improving the cooling effect on the pipe. The main body 3 is cooled, and the corresponding cooling chamber is also controlled by the external water pump 5 or the circulating water temperature control system through the pipe joint 6. This is used to strictly control the temperature of the cooling water in the corresponding cooling chamber. The temperature sensor is built into the bottom of the corresponding cooling chamber. When the main body 3 passes through the second through-pipe 11, the water stains attached to the surface of the main body 3 are scraped and cleaned by the scraper blades 12 and 13. The water droplets scraped and cleaned by the scraper blade 13 fall into the inside of the second through-pipe 11 and are finally discharged into the second cooling chamber 10 through the drain hole 14.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
