Description

Technical Field

[0001] The present application belongs to the technical field of pipe production, and specifically relates to a cooling device for polyethylene pipe production. Background Art

[0002] Polyethylene is a highly crystalline, non-polar thermoplastic resin. PE has excellent resistance to most household and industrial chemicals. Polyethylene materials are widely used, especially in the field of pipes. In the production and cooling process of polyethylene pipes, most of them use natural air cooling or water spray cooling. The air cooling time is long and the cooling effect is poor.

[0003] For example, the publication number: CN219381281U discloses a cooling device for polyethylene pipe production, which belongs to the technical field of polyethylene pipe production, including a support platform and a pipe support tube, one end of the pipe support tube is closed, and the other end is provided with a pipe inlet, and is characterized in that a mounting plate and a pipe support tube are sequentially arranged above the support platform, a water spray pipe is arranged inside the pipe support tube, and a cooling water jacket is arranged outside the pipe support tube, one end of the water spray pipe passes through the bottom seal of the pipe support tube and is placed outside the pipe support tube, a cooling water cavity is formed inside the cooling water jacket, and a water inlet pipe I and a water outlet pipe connected to the cooling water cavity are respectively arranged at both ends of the cooling water jacket, and a circulating water pipe is connected between the water inlet pipe and the water outlet pipe. The utility model is a cooling device for polyethylene pipe production, which can cool the inside of the polyethylene pipe at the same time through the cooling water jacket and the water spray pipe, so as to achieve rapid and uniform cooling of the inside and outside of the pipe, and the cooling water in the cooling water jacket can be reused, which can improve the efficiency of polyethylene pipe production.

[0004] However, in actual use, it was found that after the pipe is formed, the cooling process is relatively long, and general cooling is carried out by spraying on the outside, while the inside of the pipe is still maintained at a certain temperature. Therefore, during the cooling process, a local temperature difference between the inside and outside is often generated, causing the pipe to bend and deform. Therefore, in order to ensure that the pipe always maintains its shape and does not collapse during the cooling process, the pipe must be supported while reducing the temperature difference between the inside and outside. Utility Model Content

[0005] The purpose of the present application is to provide a cooling device for polyethylene pipe production in order to solve the above-mentioned problem that the pipe shape does not collapse during the cooling process.

[0006] The technical solution adopted in the present application is as follows: a cooling device for the production of polyethylene pipes, wherein a plurality of cooling metal hollow tubes are fixedly plugged into the side surface of the cooling box, a metal temperature transfer sleeve is fixedly connected to the outer side surface of the cooling metal hollow tube, a cooling water atomization tube is fixedly connected to the side surface of the cooling metal hollow tube, a cooling water inlet tube is fixedly plugged into the side surface of the cooling water atomization tube, a plurality of bearing vertical plates are fixedly connected to the side surface of the cooling water atomization tube, a sliding vertical groove is provided on the side surface of the bearing vertical plate, a translation rod is slidably plugged into the sliding vertical groove through the provided hole groove, a plug-in plate is fixedly connected to the side surface of the translation rod, a blower casing is fixedly connected to the side surface of one end of the cooling water atomization tube relative to the cooling metal hollow tube, a blower base is fixedly connected to the inner side surface of the blower casing, and a blower is fixedly connected to the side surface of the blower base.

[0007] By adopting the above technical solution, the operator uses the cooling metal hollow tube and the metal temperature transfer sleeve on the cooling box to plug the pipes on it, and then uses the cooling water inlet pipe to introduce water into the cooling water atomization pipe, and then uses the blower in the blower casing to blow the water into the cooling metal hollow tube, and uses the translation rod connected to the load-bearing vertical plate and the sliding vertical groove to control the plug-in board downward, thereby controlling the flow rate of the cooling water vapor to control the cooling efficiency.

[0008] The cooling box is the main body of the device, which is mainly used to place the pipes in it and cool them. The cooling metal hollow tube is a hollow pipe, into which water vapor is blown to achieve the cooling effect. The metal heat transfer sleeve is used as an intermediate component to transfer heat, so as to take away the heat inside the pipe, and the heat is transferred through the metal heat transfer sleeve, so that the process will not be too fast, thus having the same efficiency as external cooling.

[0009] The cooling water inlet pipe is a pipe for introducing cooling water. The introduced water is blown away by wind in the cooling water atomization pipe to form water mist, which can better take away heat.

[0010] The blower base in the blower housing is used to fix the blower, and the blower is used to provide airflow to drive water into the cooling metal hollow tube.

[0011] The translation rods connected to the bearing vertical plates and the sliding vertical grooves are used to drive the plug-in plates to plug downward, so as to change the inner diameter of the pipe and thus change the flow rate in the pipe. Since the dimensions of the structure are relatively close during the plug-in process, the plug-in will not be inserted all the way to the bottom, but will go down slowly.

[0012] Through the above structure, the operator can blow water mist into the pipe and put the polyethylene pipe on it, thereby ensuring that the pipe does not bend. The internal cooling speed is improved and is equivalent to the external cooling speed, which not only improves the cooling efficiency but also ensures the production quality.

[0013] In a preferred embodiment, a cooling water intermediary flow pipe is fixedly inserted into the side surface of one end of the cooling water inlet pipe relative to the cooling water atomization pipe, and a plurality of spray pipes are fixedly inserted into the side surface of the cooling water intermediary flow pipe, and a plurality of spray holes are opened on the side surface of the spray pipe.

[0014] By adopting the above technical solution, the intermediate flow pipe in the cooling water is used as the cooling water supply main pipe, and the spray pipe is used as the cooling water drainage pipe outside the spray pipe material, and sprayed out through the spray hole.

[0015] In a preferred embodiment, a cooling water pump outlet pipe is fixedly inserted into the side surface of the cooling water medium flow pipe, and a cooling water pump is fixedly inserted into the side surface of one end of the cooling water pump outlet pipe opposite to the cooling water medium flow pipe.

[0016] By adopting the above technical solution, the outlet pipe of the cooling water pump is used as the source pipe of the cooling water, and the cooling water pump is used to provide power for it.

[0017] In a preferred embodiment, a cooling water pump inlet pipe is fixedly inserted into a side surface of one end of the cooling water pump relative to the cooling water pump outlet pipe, and a water pump base is fixedly connected to the side surface of the cooling water pump.

[0018] By adopting the above technical solution, the cooling water pump inlet pipe is used as the source pipeline of the cooling water, and the cooling water pump is fixed by using the water pump base.

[0019] In a preferred embodiment, the side surface of the water pump base is fixedly connected to the water pump housing, and the bottom surface of the cooling box is fixedly connected to a plurality of supporting base plates.

[0020] By adopting the above technical solution, the water pump casing is used as a shell to protect the water pump, and the supporting bottom plate is used to support the entire device.

[0021] In a preferred embodiment, a plurality of placement holes are opened on the side surface of the cooling box, a plurality of placement hole baffle plug-in rings are fixedly connected to the side surface of the cooling box, and the placement hole baffle plug-in rings are slidably plugged with placement hole baffles through hole grooves opened on the side surface.

[0022] By adopting the above technical solution, the placement hole is used as an opening to facilitate the operator to put the pipe on the metal heat transfer sleeve. In order to avoid the outflow of water vapor during cooling, it is necessary to slide the placement hole baffle on the placement hole baffle plug-in ring to block the placement hole, and then pull it open after cooling is completed.

[0023] In a preferred embodiment, a side surface of the cooling box is rotatably connected to a flip shaft, and a flip cover is fixedly connected to a side surface of one end of the flip shaft relative to the cooling box.

[0024] By adopting the above technical solution, the flip cover is made capable of flipping by utilizing the flip shaft, so that the flip cover can be turned over, making it convenient for operators to take out the pipe after cooling.

[0025] In a preferred embodiment, a drain pipe is fixedly connected to the side surface of the cooling box.

[0026] By adopting the above technical solution, the cooling water is discharged and recycled through the drainage pipe to achieve secondary recycling.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0028] In this application, the cooling box is the main body of the device, which is mainly used to place the pipe in it and cool it. The cooling metal hollow tube is a hollow pipe, and water vapor is blown into it to achieve the cooling effect. The metal heat transfer sleeve is used as an intermediate component to transfer heat, so as to take away the heat inside the pipe, and the heat is transferred through the metal heat transfer sleeve, so that the process will not be too fast, so that the efficiency is equivalent to external cooling.

[0029] The cooling water inlet pipe is a pipe for introducing cooling water. The introduced water is blown away by wind in the cooling water atomization pipe to form water mist, which can better take away heat.

[0030] The blower base in the blower housing is used to fix the blower, and the blower is used to provide airflow to drive water into the cooling metal hollow tube.

[0031] The translation rods connected to the bearing vertical plates and the sliding vertical grooves are used to drive the plug-in plates to plug downward, so as to change the inner diameter of the pipe and thus change the flow rate in the pipe. Since the dimensions of the structure are relatively close during the plug-in process, the plug-in will not be inserted all the way to the bottom, but will go down slowly.

[0032] Through the above structure, the operator can blow water mist into the pipe and put the polyethylene pipe on it, thereby ensuring that the pipe does not bend. The internal cooling speed is improved and is equivalent to the external cooling speed, which not only improves the cooling efficiency but also ensures the production quality.
