Soaking type cooling device for plastic pipe production

Abstract

The invention provides a soaking type cooling device for plastic pipe production, and relates to the field of pipe production. The soaking type cooling device comprises cooling cylinders, wherein thecooling cylinders comprise pipe cylinders, the pipe cylinders are hollow, the top ends of the pipe cylinders communicate with the bottom ends of heat dissipation cylinders, the heat dissipation cylinders comprise outer cylinders with the bottom ends fixedly connected with the pipe cylinders, the ends of the outer cylinders are fixedly connected with inner cylinders, heat dissipation frames are fixedly connected to the inner walls of the inner cylinders, draught fans are arranged at the left ends of the heat dissipation frames in the inner cylinders, the heat dissipation frames comprises frameplates fixedly connected with the inner cylinders, and fan-shaped fins coaxial with the inner cylinders are fixedly connected to the frame plates. According to the device, the heat absorption capacityof water in unit volume is improved, the frame plates and the fan-shaped fins make full contact with the water and air respectively, the heat dissipation efficiency is improved, the purpose of savingwater is achieved, staged cooling is achieved, discharged hot water is water, making contact with pipes, in the first-stage cooling cylinder, and heat capable of being absorbed by the water per unitvolume is fully utilized.

Description

technical field [0001] The invention relates to the field of pipe production, in particular to an immersion cooling device for plastic pipe production. Background technique [0002] In the prior art, when the pipe is cooled, it is generally sprayed with cold water directly. However, due to the high temperature and low strength of the newly extruded pipe, if the pipe is directly sprayed with cold water, the pipe will suddenly be cooled, causing the pipe to shrink, thereby enhancing the brittleness of the pipe. The brittle pipe is easy to be damaged during use, and the service life is also very short, which cannot meet the required requirements. In order to avoid the brittleness of the produced pipe due to sudden cold when it is cooled, it is a problem worth studying by those skilled in the art. [0003] The patent number is CN106584809B, which discloses a cooling device for pipe production, including a cooling box. There are pipe inlets and pipe outlets on both sides of the...

[0004] However, although the immersion cooling method has a good cooling effect and the quality of the pipes produced is high, but because the water temperature rises rapidly, if the water in the water tank is cooled only by pumping in and out, it will be a waste of water. , and the heat carried by the pumped water is not high enough to make full use of the water
