Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1-5, a cooling device for PPR pipe production, including fixed upper box 1 that sets up on box 2 down and set up the tub hole 3 that advances of two symmetry settings of box 2 lateral wall down, lower box 2 inside wall is fixed to be provided with and is the cooling cylinder 4 that the concave setting in both ends sets up, and the shape and the position of cooling cylinder 4 are as shown in 2/3/4, and the both sides of cooling cylinder 4 are the concave setting, are so that make things convenient for the circulation of coolant liquid more.

The outer side wall of the cooling cylinder 4 is provided with a cooling hole 5 which is coaxial with the pipe inlet hole 3, a cooling device and a backflow mechanism are arranged in the cooling cylinder 4, and a water pump 10 which feeds liquid to the upper box body 1 is arranged at the bottom in the lower box body 2.
