[0002] With the continuous development of society and the continuous advancement of science and technology, insulated pipe is the abbreviation of insulated pipe, which is used for the transportation of liquids, gases and other media. In the thermal insulation projects of pipelines in petroleum, chemical industry, aerospace, military, central heating, central air conditioning, municipal and other industries, the insulated pipe is suitable for transporting various media in the range of -50 degrees Celsius to 150 degrees Celsius. It is widely used in the transportation of central heating, cooling and hot oil, as well as thermal insulation projects in greenhouses, cold storage, coal mines, petroleum, chemical and other industries.

[0003] When using existing environmentally friendly insulation pipe production equipment, workers are required to manually add chemical foaming agents into the foaming pipe. However, due to the high temperature inside the production equipment, this may pose a threat to the workers' personal safety. At the same time, the heat energy in the production equipment will also be wasted, thereby affecting production efficiency and costs. Utility Model Content

[0015] 2. The high temperature of the molten plastic particles is transferred through the heat transfer plate to the water tank. The water in the water tank boils and evaporates to produce high-temperature steam. The high-temperature steam enters the steam box through the air inlet pipe and L-shaped pipe. The temperature in the steam box rises with the entry of steam, which increases the reaction rate of the chemical foaming agent in the foaming tube in the steam box.

When the pressure in the steam box is too high, the push plate moves, the water outlet is exposed, and the condensed water and excess steam in the steam box will be discharged. The condensed water enters the water storage tank from the water outlet for subsequent reuse. BRIEF DESCRIPTION OF THE DRAWINGS

The high-temperature foaming device includes a reset spring 11, a foaming agent box 13, a piston plate 14, and a steam box 16. The foaming agent box 13 is fixedly connected to the inner wall of the box body 1, and the piston plate 14 is slidably connected to the foaming agent box 13. The foaming agent box 13 is fixedly connected to the annular nozzle 19 away from the box body 1. One side of the box body 1 is fixedly connected to the compression chamber 9. A thin plate 10 is slidably connected to the compression chamber 9. The thin plate 10 is made of light plastic to ensure its light weight and easy movement. The reset spring 11 It is fixedly connected between the thin plate 10 and the inner wall of the compression chamber 9. The reset spring 11 has a strong elastic force and can quickly reset the thin plate 10. A push rod 12 is fixedly connected to one side of the thin plate 10. One end of the push rod 12 is fixedly connected to the piston plate 14. The push rod 12, the compression chamber 9, and the foaming agent box 13 are all sealed. The steam box 16 is fixedly connected to one end of the box body 1. The steam box 16 is connected to the compression chamber 9 through an L-shaped tube 15. The L-shaped tube 15, the steam box 16, and the compression chamber 9 are all sealed to prevent air leakage.

[0027] The compression chamber 9 is fixedly connected to an air inlet pipe 8 at one end away from the foaming agent box 13, and a water tank 6 is fixedly connected to the box body 1. The water tank 6 is filled with water. The water tank 6 and the compression chamber 9 are connected through the air inlet pipe 8. One end of the water tank 6 is fixedly connected to a heat transfer plate 5. The end of the heat transfer plate 5 away from the water tank 6 is fixedly connected to the outer surface of the smelting chamber 2. The water tank 6 and the heat transfer plate 5 are both made of a metal material with good thermal conductivity. One end of the smelting chamber 2 is fixedly connected to a feed hopper 3. The feed port 3 is conical in shape to facilitate the entry of plastic particles into the smelting chamber 2. A rotating shaft 7 is rotatably connected to the smelting chamber 2, and an oblique thread is provided on the outer surface of the rotating shaft 7. A plurality of heating blocks 4 are fixedly connected to the smelting chamber 2, and one end of the smelting chamber 2 is fixedly connected to a cooling pipe 20. A cold water nozzle 18 is fixedly connected to one side of the box body 1, and a support rod 17 is fixedly connected between the cooling pipe 20 and the bottom wall of the box body 1. One end of the cooling pipe 20 is fixedly connected to a foaming tube 21, and the foaming tube 21 is fixedly connected to the annular nozzle 19. The annular nozzle 19 can spray the chemical foaming agent directly onto the surface of the insulation tube in the foaming tube 21. The foaming tube 21 is connected to the steam box 16, and a push plate 22 is slidably connected to the steam box 16. The steam box 16, the foaming tube 21 and the push plate 22 are all sealed. A straight spring 23 is fixedly connected between the push plate 22 and the inner side wall of the steam box 16. A water outlet is provided on the bottom wall of the steam box 16 near the straight spring 23, and a water storage tank 24 is fixedly connected to the bottom wall of the box body 1 near the steam box 16.

[0028] In the present invention, when plastic particles enter the smelting chamber 2 through the feed hopper 3, the temperature in the smelting chamber 2 rises rapidly to melt the plastic particles, so that the melt in the smelting chamber 2 enters the cooling pipe 20, and the cold water nozzle 18 sprays cooling water on the surface of the cooling pipe 20, thereby completing the cooling and shaping of the melt. The high temperature in the smelting chamber 2 is transferred to the water tank 6 through the heat transfer plate 5. The water temperature in the water tank 6 rises sharply until the water begins to boil and produces high-temperature steam. The high-temperature steam enters the compression chamber 9 through the air inlet pipe 8. The high-temperature steam gradually accumulates, thereby pushing the thin plate 10 to start moving, and the thin plate 10 drives The push rod 12 moves, and the push rod 12 drives the piston plate 14 to move. The piston plate 14 begins to squeeze the chemical foaming agent in the foaming agent box 13, so that the chemical foaming agent is pressed into the annular nozzle 19. The annular nozzle 19 evenly sprays the chemical foaming agent onto the surface of the insulation pipe that needs to be foamed, thereby completing the function of automatically spraying the chemical foaming agent by recycling the heat energy, avoiding direct contact with the high-temperature device when the worker is working and causing damage. When the pressure in the compression chamber 9 is relieved, the piston plate 14 is reset by the elastic force of the reset spring 11, so that the piston plate 14 can prepare for the next extrusion work.

[0029] At the same time, as the thin plate 10 moves, the L-shaped tube 15 at the upper end of the compression chamber 9 is exposed, and excess high-temperature steam enters the L-shaped tube 15. The high-temperature steam then reaches the steam box 16 through the L-shaped tube 15. The temperature in the steam box 16 begins to rise, and the temperature of the foaming tube 21 in the steam box 16 also rises accordingly, thereby improving the foaming efficiency of the chemical foaming agent in the foaming tube 21, and also making the insulation tube foam more uniform.

[0030] The high-temperature steam in the steam box 16 gradually condenses into water over time. As the high-temperature steam continues to enter the steam box 16, the pressure in the steam box 16 gradually increases. At this time, the push plate 22 begins to move under the pressure until the water outlet is exposed. The pressure in the steam box 16 is relieved, and the excess condensed water flows into the water storage tank 24 through the water outlet. The push plate 22 is reset by the elastic force of the straight spring 23.

[0031] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
