The insulation of hot and cold pipelines is also indispensable, which is related to the stability of the process and has an important impact on the environment and energy consumption.

[0003] The general practice of industrial pipeline insulation includes polyurethane foaming, wrapping the outer wall of the pipeline with insulation cotton, and then wrapping the outer layer with metal skin for waterproofing and anti-corrosion. This work has always been processed manually, which is time-consuming and labor-intensive, with high labor intensity and low efficiency. Population aging has become a trend in my country. At present, most of the practitioners in this industry are migrant workers over 50 years old. The high intensity, low empowerment and low income make the younger generation discouraged, and there is no successor! Utility Model Content

[0005] The technical solution adopted by the utility model is as follows:

[0006] A cold and hot pipe insulation structure comprises an upper shell and a lower shell that cooperate with each other, the upper shell is the upper half of the pipe along the axial direction, and the lower shell is the lower half of the pipe along the axial direction. The upper shell and the lower shell are coupled to each other to enclose a complete circular tube, the inner side surface of the upper shell is provided with insulation cotton, the inner side surface of the lower shell is provided with insulation cotton, a coupling groove is provided on the first end surface of the upper shell, and two ends of the coupling groove are provided with extended edges, a coupling outer edge is provided on the outer side of the second end surface of the upper shell, and two ends of the coupling outer edge are provided with extended edges.

[0009] The end surface of the heat-insulating cotton on the upper shell is flush with the end surface of the upper shell, and the end surface of the heat-insulating cotton on the lower shell is flush with the end surface of the lower shell.

[0010] The coupling grooves on the first end surface of the upper shell are distributed along the outer circumference of the upper shell, and two ends of the coupling grooves extend downward to form extension edges protruding from the upper shell, so that the coupling grooves form a semicircular groove structure.

[0011] The coupling outer edge outside the second end surface of the upper shell is distributed along the outer circumference of the upper shell, and the two ends of the coupling outer edge extend downward to form an extended edge protruding from the upper shell, and the coupling outer edge forms a semicircular bulging structure.

[0012] When the insulation sleeves are required to be extended in pairs on the left and right, the coupling grooves and coupling outer edges of adjacent insulation sleeves can be connected to each other on the left and right.

[0013] The inner diameters of the extended edge at the coupling groove of the upper shell and the extended edge at the coupling outer edge of the upper shell are slightly larger than the corresponding coupling groove and coupling outer edge of the lower shell, respectively.

[0015] The locking pins are rivets, screws or pins.

[0016] A plurality of locking bands are provided on the outer wall of the upper shell, and a plurality of corresponding locking buckles are provided on the outer wall of the lower shell. The locking bands on the upper shell correspond to the locking buckles on the lower shell one by one. When the upper shell and the lower shell are matched, the locking bands on the upper shell and the corresponding locking buckles on the lower shell cooperate with each other to form a locking buckle matching structure.

The operation is completed quickly through the coupling components of the upper shell and the lower shell, which improves work efficiency and reduces labor intensity. The utility model is customized according to the specifications of the pipeline through prefabrication.

[0024] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 4 As shown, the cold and hot pipe insulation structure described in the utility model includes an upper shell 1 and a lower shell 2 that cooperate with each other. The upper shell 1 is the upper half of the pipe along the axial direction, and the lower shell 2 is the lower half of the pipe along the axial direction. The upper shell 1 and the lower shell 2 are coupled to each other to form a complete circular tube.

[0026] The inner side of the upper shell 1 is provided with heat-insulating cotton 3, which is pressed into a whole with the upper shell 1 by high-temperature glue, and the inner side of the lower shell 2 is provided with heat-insulating cotton 3, which is pressed into a whole with the lower shell 2 by high-temperature glue. The end face of the heat-insulating cotton 3 on the upper shell 1 is flush with the end face of the upper shell 1, and the end face of the heat-insulating cotton 3 on the lower shell 2 is flush with the end face of the lower shell 2.

[0027] A coupling groove 5 is provided on the first end surface of the upper shell 1. The coupling groove 5 is distributed along the outer circumference of the upper shell 1. Extended edges 4 protruding from the upper shell 1 are extended downward from the two ends of the coupling groove 5. The extended edges 4 at the coupling groove 5 are correspondingly swung downward, and the coupling groove 5 forms a semicircular groove structure.

[0028] A coupling outer edge 6 is provided on the outer side of the second end surface of the upper shell 1, and the coupling outer edge 6 is distributed along the outer circumference of the upper shell 1. Extended edges 4 protruding from the upper shell 1 are extended downward from the two ends of the coupling outer edge 6, and the extended edges 4 at the coupling outer edge 6 are correspondingly swung downward, and the coupling outer edge 6 forms a semicircular bulging structure.

[0029] Corresponding to the upper shell 1, a coupling groove 5 is provided on the end surface of the lower shell 2, and the coupling groove 5 is distributed along the outer circumference of the lower shell 2, and the coupling groove 5 forms a semicircular groove structure. Corresponding to the upper shell 1, a coupling outer edge 6 is provided on the outer side of the end surface of the lower shell 2, and the coupling outer edge 6 is distributed along the outer circumference of the upper shell 1, and the coupling outer edge 6 forms a semicircular bulge structure.

[0030] When the upper shell 1 and the lower shell 2 are matched, the thermal insulation cotton 3 of the upper shell 1 and the thermal insulation cotton 3 of the lower shell 2 are tightly attached to each other, and the extended edge 4 at the coupling groove 5 of the upper shell 1 and the extended edge 4 at the coupling outer edge 6 of the upper shell 1 respectively clamp the corresponding coupling groove 5 and coupling outer edge 6 of the lower shell 2 to form a complete circle. When the insulation sleeves that are extended in pairs on the left and right are required, the coupling grooves 5 and coupling outer edges 6 of adjacent insulation sleeves can be connected to each other on the left and right.

[0031] It should be noted that the inner diameters of the extended edge 4 at the coupling groove 5 of the upper shell 1 and the extended edge 4 at the coupling outer edge 6 of the upper shell 1 are slightly larger than the corresponding coupling groove 5 and coupling outer edge 6 of the lower shell 2, respectively. This ensures that the extended edge 4 covers the connecting gap on the lower shell 2, thereby achieving a water-blocking effect.

[0032] A plurality of positioning rings 7 are provided on the outer wall of the upper shell 1, and a plurality of corresponding positioning rings 7 are provided on the outer wall of the lower shell 2. The positioning rings 7 on the upper shell 1 correspond to the positioning rings 7 on the lower shell 2 and are adjacent to each other in a staggered manner. When the upper shell 1 and the lower shell 2 are matched, the positioning rings 7 on the upper shell 1 and the corresponding positioning rings 7 on the lower shell 2 are inserted through the locking pins 8 to form a locking matching structure. The locking pins 8 can be structures such as rivets, screws or pins.

[0033] A plurality of locking bands 9 are provided on the outer wall of the upper shell 1, and a plurality of corresponding locking buckles 10 are provided on the outer wall of the lower shell 2. The locking bands 9 on the upper shell 1 correspond to the locking buckles 10 on the lower shell 2 one by one. When the upper shell 1 and the lower shell 2 are matched, the locking bands 9 on the upper shell 1 and the corresponding locking buckles 10 on the lower shell 2 cooperate with each other to form a locking buckle matching structure, which connects and locks the upper shell 1 and the lower shell 2.

[0034] When the pipe is insulated, the positioning ring 7 of the upper shell 1 and the corresponding positioning ring 7 of the locking pin 8 are inserted together through the locking pin 8 to form the upper shell 1 and the lower shell 2 coupled up and down, and then the locking belt 9 and the locking buckle 10 are used to lock and lock, so as to achieve the fixed connection of the whole insulation cover. The two ends of the insulation cover are connected to each other through the coupling groove 5 and the coupling outer edge 6.

[0035] The utility model structure is used for heat preservation of industrial hot and cold pipes. The operation is completed quickly through the coupling components of the upper shell and the lower shell, which improves work efficiency and reduces labor intensity. The utility model is customized according to the specifications of the pipeline through prefabrication. The insulation cotton and metal skin are pressed and assisted by high-temperature adhesive to form a finished insulation body. When installing on site, it only needs to merge the upper and lower coupling bodies, put on rivets, and tighten the locking belt to complete the insulation installation, saving time and effort. The utility model solves the dilemma of no successors in this type of work due to aging, reduces the time of on-site insulation work, and improves work efficiency; mold pressing greatly improves the aesthetics. The utility model is stable, reliable and practical.

[0036] The above description is an explanation of the utility model, not a limitation of the utility model. The utility model can be modified in any form without violating the spirit of the utility model.
