Description

Technical Field

[0001] The utility model relates to the technical field of PVC pipe processing, in particular to a cooling tank structure for PVC pipes. Background Art

[0002] As is well known, the main component of PVC pipes is polyvinyl chloride, a material added with other components to enhance its heat resistance, toughness and ductility. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. When the production of PVC pipes is completed, a PVC pipe pre-cooling device is required for pre-cooling.

[0003] In real life, most PVC pipe pre-cooling devices cool the PVC pipes by means of cold water spraying. Most of these devices generally do not collect the pre-cooled water and recycle it after cooling, resulting in a certain waste of water resources. At the same time, most of these devices can only pre-cool PVC pipes of the same diameter specification. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cooling tank structure for PVC pipes, which solves the problems of improving the cooling efficiency and saving energy consumption in the cooling of PVC pipes.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a cooling tank structure for PVC pipes, including a cooling material-passing water tank body, a cold water circulation structure connected to the cooling material-passing water tank body, and an upper spraying structure connected to the cold water circulation structure. A plurality of built-in transmission roller group structures are arranged in the cooling material-passing water tank body. The cooling material-passing water tank body includes a water tank body and an inner guide member mounting seat assembly arranged in the water tank body. The built-in transmission roller group structure includes an outer limit connection groove sleeve, a group of bushing mounting seats arranged in the outer limit connection groove sleeve, a plurality of transmission outer guide rollers arranged in the two bushing mounting seats, transmission inner guide rollers arranged between two adjacent transmission outer guide rollers, and a linkage transmission seat connected to the transmission outer guide rollers and the transmission inner guide rollers.

[0006] The cold water circulation structure includes a circulation water tank, a refrigeration unit arranged on the upper part of the circulation water tank, a circulating water collecting pipe arranged on the side end of the circulation water tank and connected to the water tank body, and a cooling water supply pipe arranged on the side end of the circulation water tank and connected to the upper spraying structure.

[0007] A drying equipment external connection frame is arranged at the discharging end of the water tank body, and a discharging equipment docking frame is arranged at the feeding end of the water tank body.

[0008] The upper spraying structure is a spray pipeline arranged in an S shape.

[0009] Advantages of the present utility model: An S-shaped upper spray structure is provided to ensure the same spraying contact amount at different positions on the circumferential side of the PVC pipe body, so that during the overall water cooling and shaping process, the surface of the PVC pipe body is stable, thereby reducing the possibility of bubbles generated on the surface of the PVC pipe body and improving the yield of the overall PVC pipe body during cooling and shaping. The connection and use of the water tank body and the cold water circulation structure ensure that the temperature of the cooling cold water is increased, and the cooling time and energy consumption are reduced. And equipment matching frames for feeding and discharging and an internal transmission roller group structure are configured to facilitate the use of the equipment and ensure smooth cooling and discharging.
