Description

Technical Field

[0001] The utility model relates to the technical field of concrete sleeper production, in particular to a device capable of rapidly reducing the temperature of coarse aggregate. Background Art

[0002] In order to ensure the quality of concrete sleepers, the relevant standards for concrete sleepers stipulate that during the production of concrete sleepers, the temperature of concrete entering the mold should be controlled in the range of 5℃ to 30℃. During the four seasons of the year, when producing concrete sleepers in spring, autumn and winter, the temperature of concrete can be lowered by reducing the temperature of cement, mixing water and fine aggregate to achieve the specified purpose.

[0003] In summer, especially in southern China, when the ambient temperature is above 30℃, the above measures can no longer guarantee the concrete mold temperature. In the concrete sleeper production mix, the weight of coarse aggregate accounts for more than 50% of the total weight of the sleeper. The change in coarse aggregate temperature directly affects the concrete mold temperature. Lowering the coarse aggregate temperature is an important guarantee for the concrete to reach the mold temperature when producing sleepers in summer. Summary of the Invention

[0004] The purpose of the utility model is to provide a device that can quickly reduce the temperature of coarse aggregate to solve the above-mentioned defects caused by the prior art.

[0005] A device capable of rapidly reducing the temperature of coarse aggregate comprises an equipment base, a return pipe being provided on one side of the equipment base, one end of the return pipe being connected to a liquid storage tank, a processing mechanism being provided directly above the equipment base, the processing mechanism performing water cooling treatment on the filled coarse aggregate, and then introducing another batch of coarse aggregate, thereby improving the processing efficiency of the coarse aggregate, and a recovery mechanism being provided directly below the equipment base, the recovery mechanism recovering the liquid that has been cooled, thereby saving the water resources required for the coarse aggregate during the cooling process.

[0006] Preferably, the processing mechanism includes a conveying pipe, a spray pipe, an electric cylinder, a cooling box, a conveying belt, a sealing cover and a drainage hole. The electric cylinder is arranged directly above the cooling box, and a sealing cover is arranged directly below the cooling box. Drainage holes are opened at equal intervals on the outside of the sealing cover. The internal shaft of the equipment base is connected to the conveying belt. The spray pipe is symmetrically arranged directly above the cooling box, and the other end of the spray pipe is connected to the conveying pipe.

[0007] Preferably, the cooling box is connected to the top of the sealing cover plate through an electric cylinder arranged directly above it.

[0008] Preferably, the recovery mechanism includes a water tank, a liquid storage tank body, a water pump, a liquid filter element and a semiconductor refrigeration plate. The water tank is installed on one side of the equipment base. The liquid storage tank body is provided directly below the equipment base. A water pump is provided inside the liquid storage tank body. The input end of the water pump is connected to the liquid filter element, and the output end of the water pump is connected to one end of the return water pipe.

[0009] Preferably, the water pump is connected to the other side of the water tank via a return pipe connected to the output end.

[0010] Preferably, the spray pipe is connected to the top of the water tank via a delivery pipe at one end.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. The present invention uses spraying cold water to quickly cool the coarse aggregate in the hopper, which can be automatically controlled by a cooling control system. Compared with the traditional cooling process, it has a fast cooling speed, improves production efficiency, and improves the production process level and product quality of concrete sleepers.

[0013] The test shows that the use of this device to cool the coarse aggregate can meet the technical requirements of concrete sleeper production for the temperature of the mixed concrete entering the mold during summer construction, significantly improve the durability of the sleeper, and have a high margin of compressive strength and various mechanical performance indicators of the concrete sleeper. After on-site testing and relevant mechanical performance inspections of the concrete sleeper, the experimental results meet the relevant technical requirements for concrete sleepers specified in relevant railway standards.

[0023] In this embodiment, the processing mechanism 8 includes a conveying pipe 4, a spray pipe 5, an electric cylinder 6, a cooling box 7, a conveying belt 9, a sealing cover plate 11 and a drainage hole 12. The electric cylinder 6 is arranged directly above the cooling box 7, and the sealing cover plate 11 is arranged directly below the cooling box 7. The outer side of the sealing cover plate 11 is evenly spaced with drainage holes 12. The internal shaft of the equipment base 1 is connected to the conveying belt 9, and the spray pipe 5 is symmetrically arranged directly above the cooling box 7. The other end of the spray pipe 5 is connected to the conveying pipe 4. The sealing cover plate 11 is driven by the electric cylinder 6 to be vertically lifted and lowered to release the material inside the cooling box 7.

[0024] In this embodiment, the cooling box 7 is connected to the top of the sealing cover plate 11 through the electric cylinder 6 provided just above, and the coarse aggregate is subjected to circulating liquid cooling treatment through the cooling box 7 .

[0025] In this embodiment, the recovery mechanism 16 includes a water tank 3, a liquid storage tank body 10, a water pump 13, a liquid filter element 14 and a semiconductor refrigeration plate 15. The water tank 3 is installed on one side of the equipment base 1. The liquid storage tank body 10 is provided directly below the equipment base 1. A water pump 13 is provided inside the liquid storage tank body 10. The input end of the water pump 13 is connected to the liquid filter element 14, and the output end of the water pump 13 is connected to one end of the return pipe 2. The liquid inside the water tank 3 is cooled by the semiconductor refrigeration plate 15 to complete the liquid recovery cycle.

[0026] In this embodiment, the water pump 13 is connected to the other side of the water tank 3 via the return pipe 2 through the output end, and the used liquid is sucked in by the water pump 13 to recycle the liquid.

[0027] In this embodiment, the spray pipe 5 is connected to the top of the water tank 3 via a delivery pipe 4 at one end, and the aggregate is vertically sprayed through the spray pipe 5 to cool the aggregate.

[0028] The practical application of this device for rapidly reducing the temperature of coarse aggregate includes the following tasks:

[0029] Step 1: During use, coarse aggregate is directly put into the interior of the cooling box 7, and then the delivery pipe 4 is opened. The interior of the liquid storage tank 10 is drained out through the delivery pipe 4, and the surface of the coarse aggregate is sprayed with liquid through the symmetrically arranged spray pipes 5. The liquid passes through the drain holes 12 and the cooled liquid is directly drained out of the interior of the cooling box 7, so that the liquid flows directly into the interior of the liquid storage tank 10. The liquid storage tank 10 sucks the liquid through the water pump 13 on one side, and the crushed stones in the liquid are filtered by the liquid filter element 14 to prevent the crushed stones from being directly introduced into the interior of the water pump 13 and causing damage to the water pump 13;

After the cooling of the coarse aggregate is completed, open the electric cylinder 6, and use the electric cylinder 6 to drive the sealing cover 11 to move vertically downward, so that the coarse aggregate is directly discharged from the interior of the cooling box 7, so that the coarse aggregate is continuously injected into the conveyor belt 9 below, and the coarse aggregate is transported horizontally by the conveyor belt 9. The cooled coarse aggregate is directly transported to the preparation hopper for use.

[0032] Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
