Premixed concrete cooling system, concrete mixing station and pump truck

Abstract

The invention relates to a premixed concrete cooling system, a concrete mixing station and a pump truck. The premixed concrete cooling system comprises a material pipe, a cooling water sleeve arrangedon the outer wall of the material pipe, a cooling water cavity in the cooling water sleeve, water spraying holes uniformly formed in the inner side face of the cooling water sleeve, a cooling water pond for storing cooling water, a cooling water circulating part, and a refrigerating part, wherein the cooling water circulating part enables cooling water to flow between the cooling water sleeve andthe cooling water pond in a circulating manner; the output end and the input end of the refrigerating part are connected with the cooling water tank; and a gap exists between the outer wall of the material pipe and the inner wall of the cooling water sleeve. The concrete mixing station comprises the premixed concrete cooling system; and the pump truck comprises the premixed concrete cooling system. The premixed concrete cooling system is used for cooling premixed concrete and is high in cooling speed and cooling efficiency.

Description

technical field [0001] The invention relates to the technical field of cooling ready-mixed concrete, in particular to a cooling system for ready-mixed concrete, a concrete mixing station and a pump truck. Background technique [0002] During the construction process, the demand for ready-mixed concrete is large, and it is often put into use directly after the mixing is completed. At this time, the temperature of the ready-mixed concrete is relatively high, and the loss of slump speed after pouring is fast, which will have a negative impact on the construction quality and construction speed. have negative impacts. [0003] For large pouring parts, too high temperature of ready-mixed concrete will lead to quality problems such as uneven stress distribution, internal cracks, and substandard strength, which will affect the service life of the building. The existing solutions mainly include the use of admixtures, It is difficult to determine the amount of admixtures and water co...

[0003] For large pouring parts, too high temperature of ready-mixed concrete will lead to quality problems such as uneven stress distribution, internal cracks, and substandard strength, which will affect the service life of the building. The existing solutions mainly include the use of admixtures, It is difficult to determine the amount of admixtures and water used to increase water consumption and cold water cooling, and it is easy to have quality problems such as segregation of ready-mixed concrete caused by over-mixing, delayed final setting time, and reduced strength.

If you use cold water to cool down, ice cubes are often used to cool down, and the workload of manual handling is very large
