Description

Technical Field

[0001] This utility model relates to the field of sand cooling technology, specifically a vertical pipe sand cooling system using Freon refrigerant. Background Technology

[0002] During construction, controlling the temperature of concrete exiting the mixer is a crucial aspect of ensuring project quality, especially during periods of high temperatures when this requirement is even more stringent. Excessive concrete exit temperature can easily lead to quality problems such as cracks, affecting the stability and durability of the building structure.

[0003] To effectively control the temperature at the concrete discharge point, pre-cooling of its constituent raw materials is a common practice, with the cooling effect of sand aggregate directly affecting the achievement of overall temperature control targets. However, due to its small particle size, high bulk density, and extremely low porosity, sand aggregate makes traditional cold air cooling methods ineffective: the flow of cold air within the sand aggregate layer is obstructed, preventing sufficient heat exchange with the sand particles, resulting in low cooling efficiency and failing to meet construction requirements.

[0004] In order to efficiently reduce the temperature of sand aggregate, thereby controlling the temperature at the concrete outlet and preventing quality problems such as cracks caused by excessive temperature, we propose a vertical pipe sand cooling system using Freon refrigerant.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a vertical tube sand cooling system for Freon refrigerant, including a mounting plate 1, a cooling box 2 fixedly mounted on the mounting plate 1, several sets of lower mounting pipes 6 fixedly connected to the top of the cooling box 2, several sets of cooling pipes 20 fixedly connected to the bottom of the lower mounting pipes 6, a compressor 11 fixedly mounted on the top of the mounting plate 1, Freon refrigerant gas being disposed in the compressor 11, an exhaust pipe 12 fixedly connected to the output end of the compressor 11, a condenser pipe 10 fixedly connected to the end of the exhaust pipe 12 away from the compressor 11, a connecting pipe 14 fixedly connected to the end of the condenser pipe 10 away from the exhaust pipe 12, an expansion valve 15 disposed on the connecting pipe 14, a lower conveying pipe 8 fixedly connected to the end of the connecting pipe 14 away from the heat dissipation fins 13, several sets of first connecting pipes 4 matching the lower mounting pipes 6 fixedly connected to the lower conveying pipes 8, and the end of the first connecting pipes 4 away from the lower conveying pipes 8 fixedly connected to the lower mounting pipes 6.

[0025] Several sets of connecting blocks 21 are fixedly connected to the inner wall of the cooling pipe 20. A central pipe 22 is fixedly connected to the inner wall of the connecting block 21. An upper mounting pipe 5 is fixedly connected to the top of the lower mounting pipe 6. The central pipe 22 passes through the upper mounting pipe 5. A second connecting pipe 23 is fixedly connected to the left end of the upper mounting pipe 5. An upper conveying pipe 7 is fixedly connected to the end of the second connecting pipe 23 away from the upper mounting pipe 5. A return pipe 9 is fixedly connected to the input end of the compressor 11. The end of the return pipe 9 away from the compressor 11 is fixedly connected to the upper conveying pipe 7.

[0026] In use, the sand and aggregate are injected into the cooling tank 2, ensuring full contact between the cooling pipe 20 and the sand and aggregate. The compressor 11 compresses the low-temperature, low-pressure Freon refrigerant gas into a high-temperature, high-pressure Freon refrigerant gas through mechanical action. Then, the high-temperature, high-pressure Freon refrigerant gas enters the condenser pipe 10 through the exhaust pipe 12, exchanges heat with the outside air, releases heat, and condenses into a high-pressure, medium-temperature Freon refrigerant liquid. This high-pressure, medium-temperature Freon refrigerant liquid then enters the connecting pipe 14, where, under the action of the expansion valve 15, it is converted into a low-pressure, low-temperature gas-liquid mixed Freon refrigerant. The low-pressure, low-temperature gas-liquid mixed Freon refrigerant... The refrigerant then passes through the lower conveying pipe 8, the first connecting pipe 4, and the lower mounting pipe 6 into the cooling pipe 20. It contacts the sand and aggregate through the pipe wall of the cooling pipe 20, where the liquid Freon refrigerant rapidly evaporates into a gaseous state under low pressure, absorbing heat from the sand and aggregate and lowering its temperature. The evaporated, low-temperature, low-pressure Freon refrigerant gas then returns to the compressor 11 through the central pipe 22, the upper mounting pipe 5, the second connecting pipe 23, the upper conveying pipe 7, and the return pipe 9, achieving cyclic cooling. This efficiently reduces the temperature of the sand and aggregate, controls the concrete outlet temperature, and prevents quality problems such as cracks caused by excessively high temperatures.

[0027] An exhaust fan 18 is fixedly mounted on the mounting plate 1. The exhaust fan 18 is matched with the condenser tube 10, which is configured as a serpentine tube. This improves the heat dissipation efficiency of the condenser tube 10 and ensures the condensation effect.

[0028] A baffle 19 is slidably installed at the bottom of the mounting plate 1. The baffle 19 matches the cooling box 2. A connecting plate 3 is fixedly connected to the right side of the baffle 19. A cylinder 17 is fixedly installed at the top of the mounting plate 1. The output end of the cylinder 17 is fixedly connected to the connecting plate 3.

[0029] After the sand and aggregate have cooled, the control cylinder 17 moves the connecting plate 3, which in turn moves the baffle 19 away from the cooling box 2, allowing the material in the cooling box 2 to be discharged quickly.

[0030] Several sets of heat dissipation fins 13 are fixedly connected to the top of the mounting plate 1, and the heat dissipation fins 13 are sleeved on the outside of the condenser tube 10. This increases the contact area between the condenser tube 10 and the air, further improving the condensation efficiency.

[0031] Cooling pipe 20 is made of copper alloy and is designed as a round tube. Copper alloy has a high thermal conductivity and good cooling effect, while the round tube design can better distribute the pressure on cooling pipe 20 and reduce the risk of damage.

[0032] Working principle: During use, sand and aggregate are injected into the cooling tank 2, ensuring full contact between the cooling pipe 20 and the sand and aggregate. The compressor 11 compresses the low-temperature, low-pressure Freon refrigerant gas into a high-temperature, high-pressure Freon refrigerant gas through mechanical work. This gas enters the condenser pipe 10 through the exhaust pipe 12. With the assistance of the exhaust fan 18 and the increased contact area of ​​the heat dissipation fins 13, it exchanges heat with the outside air, releasing heat and condensing into a high-pressure, medium-temperature Freon refrigerant liquid. Subsequently, the Freon refrigerant liquid enters the connecting pipe 14, and is converted into a low-pressure, low-temperature gas-liquid mixture state by the expansion valve 15. It then sequentially enters the lower conveying pipe 8, the first connecting pipe 4, and the lower installation pipe 6. Cooling pipe 20: Liquid Freon refrigerant rapidly evaporates into a gaseous state under low pressure. It absorbs heat from the sand and aggregate through the pipe wall of cooling pipe 20. At the same time, the central pipe 22 fixed by the connecting block 21 inside cooling pipe 20 discharges the evaporated low-temperature, low-pressure Freon refrigerant gas. It returns to the compressor 11 through the upper installation pipe 5, the second connecting pipe 23, the upper conveying pipe 7, and the return pipe 9, completing the cycle cooling. After the sand and aggregate are cooled, the control cylinder 17 drives the connecting plate 3 and the baffle 19 to move, so that the material in the cooling box 2 is discharged. The whole process achieves efficient cooling of sand and aggregate through the circulation of Freon refrigerant, so as to control the temperature of concrete outlet and prevent quality problems such as cracks caused by excessive temperature.
