Description

Technical Field

[0001] This utility model relates to the field of casting equipment, specifically to a rapid cooling device for castings. Background Technology

[0002] To improve casting efficiency, castings need to be rapidly cooled after pouring, and water cooling is currently one of the commonly used methods. However, if hot castings are cooled by immersion in water, frequent water changes are required; immersion cooling is also inconvenient for continuous conveying operations, affecting operational efficiency. If spray cooling is used, the sprayed water mostly cools the upper part of the casting first, leaving the lower part, especially the bottom, difficult to cool in a short time, which can easily lead to casting deformation or micro-cracks, affecting casting quality. In addition, whether using water immersion or water spray to cool castings, water can easily remain in the crevices or grooves of the casting, which can easily cause rust if not cleaned in time, increasing the difficulty of subsequent cleaning. Therefore, a rapid casting cooling device that can rapidly cool the casting from top to bottom through water spraying and heat exchange while continuously conveying the casting, and can also quickly blow away residual water and water vapor, thereby improving cooling efficiency and ensuring casting quality, is a problem that needs to be solved. In view of this, this case arises. Utility Model Content

The steel belt conveyor is equipped with a heat-conducting annular steel belt. The heat exchange component is equipped with a heat-conducting plate with a serpentine heat exchange tube. The heat-conducting plate is placed in the middle of the steel belt conveyor and attached to the back of the upper half of the steel belt. The blower component is equipped with a blower box. The spray component is equipped with a spray water box with spray nozzles. The spray component and the blower component are arranged in sequence, and the spray water box and the blower box are both suspended above the steel belt conveyor. The rapid cooling device for castings described in this utility model utilizes a spray assembly to spray water from above the steel belt conveyor and uses a heat-conducting plate attached to the back of the steel belt to cool the castings conveyed on the steel belt from both above and below, so that the castings are cooled as a whole during continuous conveying. A blowing assembly is used to quickly blow away the residual water and water vapor in the castings after spraying, further cooling the castings, thereby improving the cooling efficiency of the castings and ensuring the quality of the castings.

The steel belt conveyor 1, the heat exchange component 2, the spray component 3, and the blowing component 4 are all connected to the frame 5.

[0023] like Figure 1 and Figure 3 As shown, the heat-conducting plate 21 of this utility model is a square plate with internal serpentine channels that conduct heat. The heat-conducting plate 21 is made of copper plate or carbon fiber plate with high thermal conductivity. The serpentine heat exchange tube 22 is arranged in the serpentine channels inside the heat-conducting plate 21 and is in close contact with the heat-conducting plate 21.

There are several spray nozzles 32, which are distributed on the bottom wall of the spray water box 31 and communicate with the inner cavity of the spray water box 31. The water inlet 33 is connected to the middle of the top wall of the spray water box 31. The water inlet 33 can be connected to an external water supply pump by a water pipe, and a valve is installed on the connected water pipe.

[0025] like Figure 1 and Figure 5 As shown, the blower box 41 of this utility model is a closed cavity with several air outlets 411 at the bottom.
