Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing, and specifically relates to a cooling device for premixed concrete of nickel sand and gravel aggregate. Background Technique

[0002] Sand and gravel aggregate is a general term for materials such as sand, gravel (pebble), crushed stone, block stone, and dressed stone in water conservancy projects. Sand and gravel aggregate is the main building material for concrete and masonry structures in water conservancy projects. During the construction process, the demand for concrete is large. In many cases, the concrete is directly put into use after mixing. At this time, the temperature of the concrete is relatively high, and the slump loss is fast after pouring, which will have a negative impact on the construction quality and construction speed.

[0003] Publication No. CN212523787U: In the technical field of concrete precooling equipment, a premixing device for aggregate for concrete production is disclosed, including a mixing barrel. The mixing barrel includes an outer shell, an insulating layer is arranged inside the outer shell, a protective shell is arranged inside the insulating layer, an inner shell is arranged on the inner bottom side wall of the outer shell, a central shaft is inserted in the middle of the upper surface of the mixing barrel, a driven bevel gear is sleeved on the top of the outer surface of the central shaft, and a motor support seat is fixedly connected to the right side of the upper surface of the mixing barrel. For this premixing device for aggregate for concrete production, the water in the water storage tank is cooled by a semiconductor refrigeration sheet, the cooled water cools the concrete aggregate in the mixing barrel through a precooling pipe, and the cooled water is circulated back to the water storage tank through a water pump, thereby further improving the precooling effect of the aggregate precooling device, improving the precooling efficiency of the device for concrete aggregate, and reducing the waste of water resources during production.

[0004] This patent uses the circulating flow of cooling water to cool the inside of the mixing barrel. However, this cooling device is integrated with the mixing device. When mixing concrete on the construction site, multiple mixing devices are used for mixing at the same time. When using this device, it is necessary to fill the water storage tanks of each cooling device with water, resulting in a large amount of time and water resources being required when multiple mixing devices are used. At the same time, using semiconductor refrigeration sheets to cool the circulating cooling water requires a large amount of electric energy, greatly increasing the electricity and water consumption of the mixing device.

[0029] As Figure 3 shown, the threaded circulation groove 41 is opened in the inner cavity of the agitator 1. One end of the threaded circulation groove 41 is communicated with the rear end of the water inlet pipe 42, and the other end of the threaded circulation groove 41 is communicated with the front end of the water outlet pipe 43. The rear end of the water outlet pipe 43 and the front end of the water inlet pipe 42 both penetrate through the agitator 1 and extend to the outside of the agitator 1.

[0030] As Figure 3 shown, the cooling water flows in the threaded circulation groove 41 to absorb the heat of the concrete in the agitator 1.

[0031] As Figure 1As shown, the right end of the water inlet pipe 42 is connected to the left end of the No. 1 connecting pipe 44 through a connector, the right end of the water outlet pipe 43 is connected to the left end of the No. 2 connecting pipe 45 through a connector, the outer surface of the No. 1 connecting pipe 44 is fixedly connected to the inner surface of the No. 1 connecting vessel 46, and the outer surface of the No. 2 connecting pipe 45 is fixedly connected to the inner surface of the No. 2 connecting vessel 47.

[0032] like Figure 1 As shown, both the No. 1 communicating vessel 46 and the No. 2 communicating vessel 47 are valves with multiple ports. The No. 1 communicating vessel 46 can allow the cooling water to flow into multiple No. 1 communicating pipes 44 respectively, and the No. 2 communicating vessel 47 can allow the cooling water in multiple No. 2 communicating pipes 45 to flow into the spray pipe 24.

[0033] like Figure 1 As shown, the top of the water pump 21 is connected to the outer surface of the water storage tank 26 through the two ends of the water suction pipe 22, the back of the water pump 21 is connected to the right side of the No. 1 connecting vessel 46 through the two ends of the water filling pipe 23, the left end of the spray pipe 24 is connected to the right side of the No. 2 connecting vessel 47, and the bottom end of the spray pipe 24 is connected to the top of the nozzle 25.

[0034] like Figure 2 and 3 As shown, the inner surface of the cooling rack 271 is fixedly connected to the outer surface of the water flow plate 272, the bottom end of the spray pipe 24 passes through the cooling rack 271 and extends to the interior of the cooling rack 271, the outer surface of the fixed frame 275 is fixedly connected to the inner surface of the cooling rack 271, and the inner surface of the fixed frame 275 is fixedly connected to the outer surface of the motor 273.

Then connect multiple first connecting pipes 44 to the first connector 46 and multiple second connecting pipes 45 to the second connector 47. Then, the water pump 21 fills the water in the water storage tank 26 into the irrigation pipe 23 through the suction pipe 22. Then, the cooling water is poured from the first connector 46 into multiple first connecting pipes 44 through the irrigation pipe 23. The cooling water is poured from the first connecting pipe 44 into the water inlet pipe 42, and then into the threaded circulation groove 41 in the mixer 1 to flow, cooling the mixing mechanism 3 in the mixer 1. Then, the cooled cooling water is poured into the water outlet pipe 43 from the other end of the threaded circulation groove 41. The cooling water then enters the second connector 47 from the second connecting pipe 45, and then is concentrated and poured into the spraying pipe 24 from the second connector 47 and sprayed out from the nozzle 25. The sprayed cooling water will fall onto the flowing water plate 272. Then, the motor 273 drives the rotating shaft 274 to rotate, and the rotating shaft 274 drives the cooling blades 276 to rotate to cool the cooling water on the flowing water plate 272. The cooling water that has undergone flowing water cooling will fall into the water storage tank 26 from here, enabling the cooling water to be recycled.
