AI Technical Summary
The existing cooling methods of PE corrugated pipe production lines are inefficient, especially at the downward-facing cut points of the pipe body, where complete cooling is not possible, and the surrounding environment is humid with water stains.
An internal and external water tank circulation cooling system is adopted. The water pump circulates the overflowing cooling water back to the internal water tank. Combined with the design of guide rollers and guide plates, it ensures that the pipe body is completely immersed and accelerates cooling, avoiding water splashing.
It achieves comprehensive cooling of the pipe body, improves cooling efficiency, and reduces water waste and the humidity problem of the surrounding environment.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of equipment related to the production of PE corrugated pipes, specifically a cooling device for PE corrugated pipes. Background Technology
[0002] The PE corrugated pipe production line includes extrusion molding, cooling, cutting, and weighing. The current cooling method involves setting up a water spray pipe between the extruder and the cutting device to spray cold water onto the PE corrugated pipe. This method has low cooling efficiency for the pipe body, especially at the downward-facing cutting point, which cannot be completely cooled, resulting in dampness and water stains around the production line.
[0003] Therefore, in order to correct the above-mentioned defects, we propose a PE corrugated pipe cooling device. Utility Model Content
[0004] The technical problem solved by this utility model is to provide a cooling device for PE corrugated pipes.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a PE corrugated pipe cooling device, which is located on a PE corrugated pipe production line and is used to cool the PE corrugated pipe after extrusion molding. It includes an inner water tank and an outer water tank. The inner water tank is supported inside the outer water tank by a support block. The inner water tank has material passage holes on both sides. The uppermost end of the material passage hole is spaced from the uppermost end of the inner water tank. The PE corrugated pipe enters from the material passage hole on one side and exits from the material passage hole on the other side. The upper end of the outer water tank is lower than the lowermost end of the material passage hole. A water circulation device is installed inside the outer water tank. The water circulation device reintroduces water overflowing from the inner water tank into the inner water tank.
[0006] Furthermore, guide rollers are installed on both sides of the inner side of the outer water tank via bearings, with the two guide rollers corresponding to the two material passage holes respectively.
[0007] Furthermore, the guide roller has a plurality of equidistant ridges on its outer side, and the gap between two ridges can just accommodate the protrusions on the outer wall of the PE corrugated pipe.
[0008] Furthermore, guide plates are installed on both sides of the inner water tank, and the guide plates are located below the material passage hole on the same side.
[0009] Furthermore, the water circulation device includes a water pump located inside an outer water tank, a cooling water tank outside the outer water tank, and a circulation pipe connecting the cooling water tank and the water pump. The outlet end of the cooling water tank is connected to a water pipe, and the outlet end of the water pipe faces the inner water tank.
[0010] Furthermore, support plates are installed on both sides of the upper end of the inner water tank, and a support rod is installed between the two support plates, with the outlet end of the water pipe tied to the support rod.
[0011] Compared with the prior art, the beneficial effects of this utility model are: This device utilizes the water circulation in the inner and outer water tanks to ensure that the pipe is completely immersed in water when it passes through, which not only accelerates the cooling speed of the pipe but also ensures that the pipe is completely cooled, while preventing water from splashing around the production line and avoiding water waste.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] This utility model provides a technical solution:
[0019] Please see Figure 1-3 A PE corrugated pipe cooling device is installed on a PE corrugated pipe production line for cooling PE corrugated pipes after extrusion molding. The device includes an inner water tank 2 and an outer water tank 1. The inner water tank 2 is supported inside the outer water tank 1 by a support block 3. The inner water tank 2 has material passage holes 7 on both sides. The uppermost end of the material passage hole 7 is spaced from the uppermost end of the inner water tank 2. The PE corrugated pipe enters from the material passage hole 7 on one side and exits from the material passage hole 7 on the other side. The upper end of the outer water tank 1 is lower than the lowermost end of the material passage hole 7, that is, the pipe body passes through the inner water tank 2. The section of the pipe body in the inner water tank 2 is completely immersed in cooling water. The overflowing cooling water enters the outer water tank 1. The water in the outer water tank 1 is introduced into the cooling water tank by a water pump 4. The water in the cooling water tank is introduced into the inner water tank 2 by a water pipe 5, thereby forming a water circulation.
[0020] The inner water tank 2 has support plates installed on both sides of its upper end, and a support rod 6 is installed between the two support plates. The outlet end of the water pipe 5 is tied to the support rod 6, so that the water pipe 5 can be pre-filled with cold water.
[0021] To prevent the pipe from slipping during entry and exit, guide rollers 9 are installed on both sides of the outer water tank 1 via bearings. The two guide rollers 9 correspond to the two feed holes 7 respectively, thus supporting the pipe. The guide rollers 9 have several equidistant ridges 10 on their outer sides. The gap between two ridges 10 can accommodate the protrusions on the outer wall of the PE corrugated pipe. The inner water tank 2 also has guide plates 8 installed on both sides. The guide plates 8 are located below the feed holes 7 on the same side, so that the water overflowing from the feed holes 7 will flow onto the guide plates 8, increasing the travel distance of the water flow into the outer water tank 1. The water can also flow down the guide plates 8 in a waterfall-like manner, allowing the heat of the water to dissipate.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
