Embodiment 1

[0015] figure 1 The air-cooling device shown is used for plastic-coated steel strips, which includes a housing 1, an air duct 2, a connecting pipe 3 and an air chamber 4. The shell 1 is a rectangular shell, which is the main component of the air cooling device. The flat shell 1 is placed between the steel strip plastic coating section and the winding section of the polyethylene pipe production line in the length direction, and the plastic coated steel strip passing through 5 runs through the shell 1 through the open slot 1.1 centered at both ends, that is, the plastic-coated steel strip 5 enters from the open slot 1.1 at the right end of the shell 1, and then passes through the open slot 1.1 at the left end of the shell 1. The air chamber 4 is rectangular, and the upper and lower inner walls of the housing 1 are equidistantly arranged along the longitudinal direction of the air chambers 4. In this embodiment, because the plastic-coated steel belt is only 57.5mm, the front and ...

Embodiment 2

[0017] In this embodiment, since the plastic-coated steel has a bandwidth of 182 mm, the stored heat is large, and more compressed air is required for cooling, so a larger size and a larger number of air injection holes 4.1 are selected. On the basis of the same structure, the air chamber 4 in this embodiment is provided with five jet holes 4.1 with a diameter of Ф20 mm, so that the technical effect similar to that of the embodiment 1 can be obtained.

Abstract

The invention discloses an air cooling device used after steel band plastic coating. The air cooling device comprises a shell, air ducts, connecting tubes and air chambers, wherein the shell is a rectangular shell; the horizontally-placed shell is arranged between a steel band plastic coating workshop section and a winding workshop section of a polyethylene pipe production line along the length direction; open slots in the middles of two ends of a favoured way through which a plastic-coated steel band passes penetrate through the shell; the air chambers are rectangular and are transversely arranged at equal intervals on the upper and lower inner walls of the shell along the length direction; each air chamber is connected with the air duct by virtue of one connecting tube so as to form an air supply passage; blow holes are uniformly distributed in one surface, which is opposite to a plastic-coated steel band, of each air chamber. According to the air cooling device, compressed air introduced for an air supply station is adopted for cooling, operation noise of a blower does not exist in a production field, the production environment is greatly purified, operators are prevented from being subjected to noise pollution, and the working efficiency can be well improved.

Description

technical field [0001] The invention relates to a device for cooling the temperature by using wind flow, in particular, the invention relates to an air cooling device used for plastic-coated steel strips in polyethylene pipe production lines. Background technique [0002] Steel strip plastic coating is an important section in the polyethylene pipe production line, and its operation directly affects the efficiency of the production line. When the steel belt is coated with plastic, the pulled steel belt is first heated to the set temperature during the movement, and then the plastic coating operation is carried out. The plastic-coated layer in a hot state has low strength and poor adhesion, and it is not suitable to immediately enter the post-winding section to be wound into a tube. The existing commercial polyethylene pipe production line is equipped with an air cooling device between the plastic coating and winding sections. The device uses an external fan and pipeline to i...
