referring to fig. 5-7, in the embodiment of the present invention, a circulating water cooling apparatus for PVC pipe production, wherein the inner side of the fixed link 22 is provided with a water inlet through hole 34, the center of the side of the water-cooling ring 20 is provided with a middle feeding hole 35, the inner side of the connecting side rod 28 is provided with an air inlet hole 36, the center of the side of the air ring 26 is provided with an air hole 37, the side of the air hole collar 27 away from the air ring 26 is provided with an air outlet groove 38, the inner side of the air box 3 is connected to a main air box 39 by a horizontal bolt, the water inlet through hole 34 is provided at the inner side of the top fixed link 22 of the water-cooling ring 20 and is connected to the inside of the water-cooling ring 20, the air inlet hole 36 is provided at the inner side of the top connecting side rod 28 of the air ring 26, the air inlet hole 36 is connected to the inside of the air guide hopper 40, the inside of the air outlet groove 38 is connected to the inside of the air ring 26, the bottom surface of the top wind body box 3 is welded with a wind guide hopper 40.

The components are standard parts in general or known to those skilled in the art, and their structure and principle are known to those skilled in the art through technical manuals or through routine experimentation.

The working principle of the invention is as follows:

one end of the pipe body enters from a side feeding slotted hole 8 of the main processing box 1, so that the inserting end penetrates through the feeding slotted hole 8 and then enters between the transmission rollers 17, the control panel 7 is set to enable the compressor 11 to work, the condenser pipe 13 forms a low-temperature state inside the inner heat-insulating layer 12, the inner heat-insulating layer 12 and the sealing rubber strip 9 are isolated and insulated so that the temperature cannot be lost, the transmission rollers 17 are enabled to perform clamping transmission on the pipe body under the support of the abutting springs 19 and the elastic telescopic rods 31, one end of the pipe body moves to a middle feeding hole 35 in the central position of the water-cooling ring body 20, one end of the pipe body extends to the central position of the cooling cloth 21, the water body is injected into the water inlet hole 29 through the water inlet pipeline 5, the water body enters into the water-cooling ring body 20 through the transmission of the water inlet through holes 34, and the water body is enabled to be immersed into the cooling cloth 21 under pressure, the cooling cloth 21 with water body is covered on the outer side wall of the pipe body for cooling treatment, the continuous low temperature state in the inner heat-insulating layer 12 ensures that the cooling effect of the cooling cloth 21 is better, one end of the pipe body horizontally extends to the inside of the material conveying through hole 24 at the central position of the isolating vertical plate 23 through a multiple cooling structure, the pipe body is transmitted under the same structure of the transmission roller 17, the outflow water body on the cooling cloth 21 is dripped into the inner bottom surface of the inner heat-insulating layer 12 and then is discharged and collected for reuse through the drainage pipe 6 under the extraction of the extraction pump 25, the end of the pipe body after cooling is inserted into the inner side position of the air body hole 37, the air blown out of the main air box 39 before insertion enters the inside of the air guide opening sleeve ring 27 under the guide of the air guide hopper 40 and then is blown out from the air outlet groove 38 at one side of the air opening sleeve ring 27, and the drying effect is carried out on the outer side inserted into the pipe body, the water body falls into the inner bottom surface of the inner heat-insulating layer 12 under the blowing of wind power, is discharged through the drainage pipeline 6 under the pumping of the pumping pump 25 and collected for reuse, and finally, the air-dried pipe body extends out of the feeding slot hole 8 on the other side of the main treatment box 1 for collection treatment.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention are equivalent to or changed within the technical scope of the present invention.
