Cooling units for pipe production

Abstract

The invention relates to a cooling device, and in particular relates to a cooling device for pipe production. The cooling device for the pipe production comprises a cooling box, wherein a pipe inlet and a pipe outlet are correspondingly formed in two sides of the cooling box. The cooling device for the pipe production is characterized by further comprising a water cooling mechanism, a circulating pipe and a circulating pump; a plurality of separating plates are vertically arranged in the cooling box; a pipe hole is coaxially formed in each separating plate; openings are alternatively arranged in top and bottom between every two adjacent separating plates; two ends of the circulating pipe correspondingly communicate with the top parts of two sides of the cooling box; the water cooling mechanism and the circulating pump sequentially communicate with the circulating pipe. The cooling device for the pipe production is applicable to the pipe cooling; cooling water enters from a low-temperature part, in the cooling box, of a pipe, and gradually flows to a high-temperature part of the pipe, and the heat of the pipe is absorbed through the cooling water, so that the temperature of the cooling water fits the temperature of the high-temperature part of the pipe, and gradual cooling is achieved, and as a result, the brittleness, caused by meeting cold suddenly, of the pipe, can be avoided.

Description

technical field [0001] The invention relates to a cooling device, in particular to a cooling device for pipe production. Background technique [0002] At present, plastic pipes are widely used in various fields of life, such as urban water supply, agricultural irrigation and other fields. The production process of plastic pipes is as follows: firstly, the pretreated raw materials are matched with the mold through a single-screw machine or a twin-screw machine, extruded into a pipe, the extruded pipe is cooled, and finally wound into a disk by a winding machine store. 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...

Problems solved by technology

Although this multi-stage cooling method effectively avoids the brittleness of the pipe due to sudden cooling, the installation of multiple cooling boxes lengthens the production line of the pipe, which requires more space and makes the production workshop crowded; In addition, the demand for cooling water has also increased, and the provision of cooling water at different temperatures requires the consumption of other resources, such as electricity and gas, which increases the cost
