Cooling and shaping device for PE 100-grade polyethylene pipe production

Abstract

The invention relates to the technical field of polyethylene pipe production, and particularly relates to a cooling and shaping device for PE 100-grade polyethylene pipe production. The cooling and shaping device comprises a cooling box, wherein a bottom plate is arranged at the bottom end of the interior of the cooling box; supporting plates which are distributed at equal intervals are arranged at the top end of the bottom plate; the supporting plates are of arc-shaped structures; grooves are formed in the inner concave surfaces of the supporting plates; a plurality of cooling fins are arranged in the grooves; drainage holes are formed in the outer walls of the two sides of the supporting plates; connecting rods of arc-shaped structures are arranged at one of the ends of the supporting plates; sleeves are arranged at the top ends of the connecting rods; connecting pipes are inserted into the inner walls of the sleeves in a penetrating mode; and water spraying pipes are arranged at oneends of the connecting pipes. According to the cooling and shaping device, the defects in the prior art are overcome, the inner wall and the outer surface of a pipe can be cooled at the same time, sothat the cooling speed of the pipe is greatly increased, shaping of the pipe is facilitated, and the problem that the pipe forming effect is poor due to the fact that the pipe is not uniformly cooledis solved.

Description

technical field [0001] The invention relates to the technical field of polyethylene pipe production, in particular to a cooling and setting device for PE100 grade polyethylene pipe production. Background technique [0002] PE pipe At present, in China's municipal pipe market, plastic pipes are developing steadily. PE pipes, PP-R pipes, and UPVC pipes all occupy a place. Among them, the strong development momentum of PE pipes is the most eye-catching, and PE pipes are used in a wide range of fields. Among them, water supply pipes and gas pipes are the two largest application markets. [0003] After searching, the patent with the publication number CN205905398U discloses a cooling and cooling device for polyethylene pipe production, which includes a cooling water jacket, a polyethylene pipe channel, a front-end air-cooled jacket and a rear-end air-cooled jacket. The outer side of the vinyl pipe channel is provided with a cooling water jacket, the upper end of the cooling wate...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a cooling and shaping device for the production of PE100 grade polyethylene pipes, which overcomes the deficiencies of the prior art and effectively solves the problem of slow cooling speed due to the single cooling treatment on the outer surface of the pipe. , it is also easy to cause uneven cooling of the pipe, which leads to the problem of poor pipe forming effect
