Description

Technical Field

[0001] This invention relates to the field of circulating cooling technology, specifically a device for circulating cooling of a material tank using water refrigeration. Background Technology

[0002] Expanded polystyrene foam is chemically stable, has a long service life, does not pollute the surrounding environment, is self-extinguishing when ignited, and only carbonizes without dripping during combustion. The carbonized layer retains its size and shape essentially unchanged, effectively preventing air from entering and inhibiting the spread of fire, thus providing excellent fire safety performance. The continuous, dense skin and nearly 100% high-strength interconnected closed-cell structure of expanded polystyrene foam provide ideal water impermeability; therefore, it is widely used in the construction industry. To shorten curing time and increase working time, expanded polystyrene foam needs to be stored at low temperatures in the container, which necessitates cooling the container.

[0024] Please see Figures 1-6 In this embodiment of the invention, a water-cooled circulating cooling device for a material barrel includes a water-cooled material barrel 1 and a cooling water tank 7. A stirring mechanism 4 is embedded in the upper end of the water-cooled material barrel 1, and a discharge valve 12 is fixedly connected to the bottom end of the water-cooled material barrel 1. The foaming adhesive inside the water-cooled material barrel 1 can be released through the discharge valve 12. A pressure gauge 3 is installed on the top of the water-cooled material barrel 1 near the stirring mechanism 4, allowing observation of the pressure inside the water-cooled material barrel 1. A safety valve 5 is installed on the other side of the top of the water-cooled material barrel 1 near the stirring mechanism 4, allowing excess gas inside the water-cooled material barrel 1 to be discharged, ensuring its safety. The water-cooled cylinder 1 is equipped with a feeding valve 2 on its left side. Foaming adhesive can be added into the water-cooled cylinder 1 through the feeding valve 2 for storage of the produced foaming adhesive. The upper side of the water-cooled cylinder 1 is fixedly connected to a cooling water return pipe 6, and the lower side of the water-cooled cylinder 1 is fixedly connected to a cooling water inlet pipe 11. One end of the cooling water inlet pipe 11 is connected to a filter 10, and the lower end of the filter 10 is equipped with a circulating water pump 9. The input end of the circulating water pump 9 is fixedly connected to a cooling water connecting pipe 13, and one end of the cooling water connecting pipe 13 is connected to a cooling water tank 7. A pneumatic heat dissipation mechanism 8 is provided on the rear side of the cooling water tank 7.

[0025] exist Figure 1 and Figure 2In the water-cooled cylinder 1, an outer shell 101 and an inner liner 104 located inside the outer shell 101 are provided with a cylinder cover plate 106 at their upper ends. A return water inlet 103 is provided at the upper end of the outer wall of the outer shell 101, and a water inlet 102 is provided at the lower end of the outer wall of the outer shell 101. A first glass tube level gauge 105 is fixedly connected to the outer wall of the inner liner 104 through the outer wall of the outer shell 101. The water level of the foaming adhesive in the inner liner 104 can be observed through the first glass tube level gauge 105. A cavity is provided between the outer shell 101 and the inner liner 104, and a first temperature sensor 107 is installed in the cavity. The first temperature sensor 107 can monitor the temperature of the cooling water in the air. The return water port 103 is fixedly connected to the cooling water return pipe 6, and the inlet water port 102 is fixedly connected to the cooling water inlet pipe 11. The cooling water enters the cavity between the outer shell 101 and the inner liner 104 from the cooling water inlet pipe 11. The cooling water absorbs the heat of the foam adhesive in the inner liner 104. The heated cooling water then flows back to the cooling water tank 7 from the cooling water return pipe 6 for cooling again.

[0026] exist Figure 2 and Figure 3 In the process, the stirring mechanism 4 includes a first motor 41 and a reduction gearbox 42 fixed to the output end of the first motor 41. The output end of the reduction gearbox 42 is fixedly connected to a coupling 45, and both ends of the left side of the outer side of the reduction gearbox 42 are fixedly connected to a bracket 43. The lower end of the coupling 45 is fixedly connected to a stirring shaft 46. At least two sets of stirring blades 44 are fixedly connected to the outer side of the stirring shaft 46. The bracket 43 is fixedly installed in the middle of the top of the material cylinder cover plate 106. The stirring blades 44 and the stirring shaft 46 are both located inside the inner liner 104. The first motor 41 drives the reduction gearbox 42 to rotate, and the reduction gearbox 42 drives the stirring shaft 46 and the stirring blades 44 to rotate together. Thus, the foaming adhesive inside the inner liner 104 can be stirred by the stirring blades 44, thereby making the foaming adhesive have better fluidity.

[0027] exist Figure 4 The cooling water tank 7 includes a tank shell 71 and a second glass tube level gauge 75 fixed to the outer wall of the tank shell 71. A water distributor 73 is embedded in the middle of the upper end of the tank shell 71. An air filter 74 is embedded in the upper end of the tank shell 71 near the rear side of the water distributor 73. A cooling fan 76 is embedded in the upper end of the tank shell 71 near the front side of the water distributor 73. A second temperature sensor 72 is embedded in the upper end of the tank shell 71 near the right side of the water distributor 73. The water level of the cooling water in the tank shell 71 can be observed through the second glass tube level gauge 75. The cooling fan 76 can dissipate the heat inside the tank shell 71 to achieve cooling. The temperature of the cooling water inside the tank shell 71 can be monitored through the second temperature sensor 72.

[0028] exist Figure 4 and Figure 5 In this device, the water distributor 73 includes a distributing plate 731 and several distributing pipes 738 fixed to the outside of the distributing plate 731. A rotating pipe 739 is fixedly connected to the upper end of the distributing plate 731. A rotary joint 733 is installed at the upper end of the rotating pipe 739, and a driven gear 732 is fixedly connected to the outside of the rotating pipe 739. A fixed pipe 734 is connected to the upper end of the rotary joint 733. A driving gear 737 is meshed with the outside of the driven gear 732. A connecting shaft 736 is fixedly connected to the upper end of the driving gear 737. A second motor 735 is fixedly connected to the upper end of the connecting shaft 736. The second motor 735 and the fixed pipe 734 are both fixed to the upper end of the water tank shell 71. The distributing pipes 738 are located inside the water tank shell 71. The upper end of the fixed pipe 734 is fixedly connected to the cooling water return pipe 6. The heated cooling water enters the fixed pipe 734 from the cooling water return pipe 6, and then passes through the rotary joint 733, the rotating pipe 739 and the liquid distribution plate 731 in sequence before being distributed into each water distribution pipe 738. The water is then sprayed out from the outlet, which makes the heated cooling water cool down quickly. The second motor 735 drives the connecting shaft 736 and the drive gear 737 to rotate together. The drive gear 737 meshes with the driven gear 732 to make the rotating pipe 739, the liquid distribution plate 731 and the water distribution pipe 738 rotate. The centrifugal force throws the water droplets out, which further improves the heat dissipation effect.

[0029] exist Figure 1 and Figure 6 In the pneumatic cooling mechanism 8, an air compressor 81 is included. An air inlet pipe 82 is fixedly connected to the output end of the air compressor 81. An ejector 83 is installed at one end of the air inlet pipe 82. A water inlet pipe 84 is connected to one end of the ejector 83, and a mixing pipe 86 is connected to the other end of the ejector 83. A bubble disc 85 is fixedly connected to one end of the mixing pipe 86. The bubble disc 85 is installed at the lower end of the interior of the water tank shell 71. One end of the water inlet pipe 84 is fixedly connected to the cooling water connecting pipe 13. Compressed air is generated by the air compressor 81 and flows from the air inlet pipe 82 into the ejector 83. A small portion of the cooling water in the cooling water connecting pipe 13 enters the water inlet pipe 84 and then enters the ejector 83. The cooling water and compressed air merge in the ejector 83 and generate a jet. After passing through the mixing pipe 86, the jet is sprayed out from the upper end of the bubble disc 85, thereby stirring the cooling water in the water tank shell 71 and further improving the cooling efficiency of the cooling water.

[0030] The working principle of this invention is as follows: When it is necessary to cool the foaming adhesive in the inner liner 104, firstly, the circulating water pump 9 is turned on. The circulating water pump 9 draws the cooling water from the cooling water tank 7 into the cooling water connecting pipe 13. After being filtered by the filter 10, the cooling water enters the cavity between the outer shell 101 and the inner liner 104 from the cooling water inlet pipe 11. The cooling water absorbs the heat of the foaming adhesive inside the inner liner 104, thereby cooling down the foaming adhesive and causing the cooling water to heat up. The heated cooling water then flows back from the cooling water return pipe 6 to the fixed pipe 734, and then passes through the rotary joint 733, the rotating pipe 739, and the liquid distribution plate 731 in sequence before being distributed into each water distribution pipe 738. Finally, it is sprayed out from the water outlet, thereby rapidly cooling down the heated cooling water. At the same time, the second motor 735 is turned on, which drives the connecting shaft. 736 and the drive gear 737 rotate together. The drive gear 737 meshes with the driven gear 732, causing the rotating pipe 739, the liquid distribution plate 731, and the water distribution pipe 738 to rotate. Centrifugal force throws water droplets out, further improving the heat dissipation effect. Next, the air compressor 81 is turned on, generating compressed air. The compressed air enters the ejector 83 from the air inlet pipe 82. At the same time, the cooling water drawn by the circulating water pump 9 enters the cooling water connecting pipe 13. A small portion of the cooling water enters the water inlet pipe 84 from the cooling water connecting pipe 13, and then enters the ejector 83 from the water inlet pipe 84. The cooling water and compressed air merge in the ejector 83 and generate a jet. After passing through the mixing pipe 86, the jet is sprayed out from the top of the bubble plate 85, thereby stirring the cooling water in the water tank shell 71 and further improving the cooling efficiency of the cooling water.
