Description

Technical Field

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

[0002] In the construction industry, especially during high-temperature seasons when concrete work is being carried out, ensuring that the concrete pouring temperature meets design requirements is crucial. Currently, to achieve this goal, pre-cooling of aggregates is a common practice.

[0003] However, cooling sand aggregate, a crucial component of concrete, has always been a challenge. Due to the small particle size and low porosity of sand particles when packed together, cold air struggles to make sufficient contact with the aggregate, rendering traditional air cooling methods ineffective. While other cooling methods such as vacuum cooling and liquid nitrogen cooling can achieve sand cooling, they require specialized equipment, resulting in high investment costs, high operating costs, complex operations, and stringent requirements for the construction environment and personnel. To achieve simple and efficient cooling of sand aggregate and ensure that the concrete pouring temperature meets design requirements, we propose a vertical cooling pipe sand cooling system. Utility Model Content

Several sets of liquid supply manifolds are fixedly connected to the top of the sand cooling chamber. Several sets of vertical cooling pipes are fixedly connected to the bottom of the liquid supply manifolds. A return manifold is fixedly connected to the top of the liquid supply manifolds. A partition completely separates the liquid supply manifolds from the return manifolds. A liquid supply branch pipe is fixedly connected to the front of the liquid supply manifold, and a main liquid supply pipe is fixedly connected to the end of the branch pipe away from the liquid supply manifold. A return branch pipe is fixedly connected to the front of the return manifold, and a main return pipe is fixedly connected to the end of the branch pipe away from the liquid supply manifold.

[0007] Preferably, a second partition plate is fixedly connected to the inner wall of the vertical cooling pipe, and a first partition plate is fixedly connected to the top of the second partition plate. The first partition plate is fixedly connected to the inner wall of the liquid supply manifold.

[0008] Preferably, each of the two sets of baffles is fixedly connected to a connecting plate at one end that is far apart from each other, and two sets of cylinders are hingedly installed on the sand cooling chamber, with the output end of the cylinders hinged to the connecting plate.

[0009] Preferably, the return manifold is configured as a triangular hollow pipe.

[0020] 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.

[0021] Please see Figure 1-4This utility model provides a technical solution: a vertical cooling pipe sand cooling system, including a sand cooling chamber 1, two sets of baffles 2 are hinged to the bottom of the sand cooling chamber 1, several sets of liquid supply manifolds 6 are fixedly connected to the top of the sand cooling chamber 1, several sets of vertical cooling pipes 9 are fixedly connected to the bottom of the liquid supply manifolds 6, a return manifold 5 is fixedly connected to the top of the liquid supply manifolds 6, a partition is provided between the liquid supply manifolds 6 and the return manifolds 5 to completely separate them, a liquid supply branch pipe 13 is fixedly connected to the front side of the liquid supply manifolds 6, a main liquid supply pipe 8 is fixedly connected to the end of the liquid supply branch pipe 13 away from the liquid supply manifolds 6, a return manifold 12 is fixedly connected to the front side of the return manifolds 5, and a main return manifold 7 is fixedly connected to the end of the return manifold 12 away from the liquid supply manifolds 6.

[0022] When cooling is required, sand is poured into the sand cooling chamber 1 from above, followed by the injection of coolant into the main supply pipe 8. The coolant flows through the supply branch pipe 13 and the supply manifold 6 into the vertical cooling pipes 9, where the evenly distributed vertical cooling pipes 9 lower the sand temperature. The cooled coolant, which has increased in temperature, flows through the return manifold 5 and the return branch pipe 12 into the return main pipe 7, returning to the coolant tank for further cooling. This process circulates and cools the sand, ensuring effective cooling. After cooling is complete, the baffle 2 is opened to discharge the material. This simple and efficient method ensures that the sand aggregate is cooled, guaranteeing that the concrete pouring temperature meets design requirements. If the sand temperature is too low after cooling, resulting in frost or ice formation, hot liquid can be injected into the main supply pipe 8 to melt the frost or ice on the surface of the vertical cooling pipes 9, ensuring smooth discharge of the sand.

[0023] A second partition plate 11 is fixedly connected to the inner wall of the vertical cooling pipe 9, and a first partition plate 10 is fixedly connected to the top of the second partition plate 11. The first partition plate 10 is fixedly connected to the inner wall of the liquid supply manifold 6.

[0024] Coolant flows into the supply manifold 6 through the main supply pipe 8 and the supply branch pipe 13, is blocked by the first partition plate 10, and flows into the vertical cooling pipe 9. Under the action of the second partition plate 11, the coolant fills the vertical cooling pipe 9 and flows back to the supply manifold 6, thus avoiding the problem that the traditional U-shaped return pipe will cause some obstruction to the discharge process.

[0025] Two sets of baffles 2 are fixedly connected to connecting plates 3 at their far ends. Two sets of cylinders 4 are hinged on the sand cooling chamber 1, and the output end of the cylinders 4 is hinged to the connecting plate 3.

[0026] By controlling the cylinder 4, the connecting plate 3 can drive the baffle 2 to rotate, thereby controlling the opening and closing of the baffle 2.

[0027] The return manifold 5 is designed as a triangular hollow pipe. The triangular design prevents sand from accumulating on the surface of the return manifold 5 during the sand injection process and can also accelerate the sand flow rate to some extent.

[0028] The inner cavity of the sand cooling chamber 1 adopts a trapezoidal structure with an opening at the bottom. Compared with the traditional square chamber, the design of the trapezoidal structure with an opening at the bottom can reduce static friction and speed up the discharge speed.

[0029] The vertical cooling pipes 9 are designed as round pipes and are distributed vertically. Compared with square pipes and plate-shaped pipes, round pipes can alleviate the stress caused by uneven sand accumulation.

[0030] Working Principle: When cooling is required, sand is injected from above into the sand cooling chamber 1, and coolant is injected into the main supply pipe 8. The coolant flows through the supply branch pipe 13 and the supply manifold 6 into the vertical cooling pipe 9. The first partition plate 10 and the second partition plate 11 on the inner wall of the vertical cooling pipe 9 fill the vertical cooling pipe 9 with coolant and allow it to flow back. The uniformly distributed vertical cooling pipes 9 lower the sand temperature. The heated coolant flows through the return manifold 5 and the return branch pipe 12 into the return main pipe 7, flowing back into the coolant tank for further cooling and circulation. This simple and efficient cooling of the sand aggregate ensures that the concrete pouring temperature meets the design requirements. After cooling, the control cylinder 4, driven by the connecting plate 3, rotates and opens the baffle 2 to discharge the material. If the sand temperature is too low after cooling, resulting in frost or ice formation, hot liquid is injected into the main supply pipe 8 to melt the frost or ice on the surface of the vertical cooling pipe 9, ensuring smooth discharge of the sand.
