Description

Technical Field

[0001] This utility model relates to the field of metal surface cold treatment technology, specifically a cooling device for metal surface heat treatment. Background Technology

[0002] Metal heat treatment processes can be broadly classified into three categories: overall heat treatment, surface heat treatment, and chemical heat treatment. Metal surface heat treatment is a common method of treating the surface of metals by rapidly heating and cooling. However, when metals are heat treated, they generally need to be exposed to a high-temperature environment, so cooling is required after heat treatment.

[0003] However, when metal is cooled by cooling water, it comes into contact with the hot air outside, causing many water droplets to form on the metal surface, which affects the storage of the metal and reduces the cooling efficiency. Moreover, existing cooling devices for heat treatment of metal parts require a large amount of water resources, which is very wasteful. Utility Model Content

[0004] The purpose of this invention is to provide a cooling device for heat treatment of metal surfaces, which can achieve the cooling function and easily dry water droplets on the metal surface, thereby improving the practicality of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for metal surface heat treatment, comprising a cooling box and a drying box disposed on one side of the cooling box, wherein a through groove is provided at the connection between the cooling box and the drying box, and an inlet and an outlet are respectively provided on opposite sides of the cooling box and the drying box; a conveyor belt is disposed in the through groove, and the beginning and end of the conveyor belt pass through the inlet and the outlet respectively; a cold air plate and a spray pipe are arranged sequentially from top to bottom along the length of the top of the cooling box; a cold air fan and a pump are disposed on the top of the cooling box; the output end of the cold air fan is connected to the cold air plate through a pipe; the input and output pipes of the pump are respectively connected to the lower part of the outer wall of the cooling box and the spray pipe; the drying box is provided with an upper air distribution plate and a lower air distribution plate, the upper air distribution plate being located above the conveyor belt, and the lower air distribution plate being located between the upper and lower parts of the conveyor belt; hot air fans are disposed at the top and bottom of the drying box, and the output ends of the two hot air fans are respectively connected to the upper air distribution plate and the lower air distribution plate through pipes.

[0006] To prevent water from splashing into the drying oven, a flexible waterproof curtain is preferably provided at the top of the through groove, which is a preferred cooling device for metal surface heat treatment according to this utility model.

[0007] In order to facilitate the uniform distribution of cold or hot air, as a preferred embodiment of the cooling device for metal surface heat treatment of this utility model, cavities are provided in the interlayer of the cold air plate, the upper air distribution plate and the lower air distribution plate, and air outlets communicating with the cavities are provided through the bottom of the cold air plate and the upper air distribution plate and the top of the lower air distribution plate.

[0008] In order to facilitate the cooling of the water in the water-cooled tank, as a preferred embodiment of the cooling device for metal surface heat treatment of this utility model, a condenser is provided inside the left and right sides of the cooling tank, and a water inlet pipe and a drain pipe are provided on the cooling tank.

[0009] To facilitate water filtration and prevent impurities on metal workpieces from entering the pump, the preferred cooling device for metal surface heat treatment according to this utility model has supports on both sides of the interior of the cooling box along the width direction. Sliding filter grooves are provided on the two supports. The filter grooves are located below the conveyor belt, and the condenser, water inlet pipe, and drain pipe are all located below the filter grooves.

[0010] To facilitate the cleaning of impurities on the filter tank, as a preferred embodiment of the cooling device for metal surface heat treatment according to this utility model, a pull-out groove adapted to the filter tank is provided on one side of the cooling box along the length direction. The filter tank is located in the pull-out groove, and a handle fixedly connected to one side of the filter tank is provided in the pull-out groove; and the water inlet end of the pipe on the pump input end is located below the filter tank.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this invention, surface-heat-treated metal workpieces are placed on a conveyor belt for transport. The workpieces are then transported to a cooling chamber, where a cooling fan and pump are activated. Air distribution plates ensure that cold air is blown evenly downwards, and the combination of cold air and water accelerates the cooling process. The cooled workpieces then enter a drying chamber where hot air fans at the top and bottom are activated. Hot air is evenly blown onto the workpieces from both the top and bottom sides via upper and lower air distribution plates, effectively drying any water droplets on the metal surface and preventing them from affecting the metal's storage. Furthermore, the cooled water is collected at the bottom of the cooling chamber for further filtration and cooling, reducing water waste. Attached Figure Description
