Embodiment Construction
[0027] Such as figure 1 As shown, a quenching device for granular materials with a circular cross-section includes a box 2 containing a coolant, and the box 2 is provided with a cooling liquid inlet 12 and a cooling liquid outlet 3. The quenching device also includes a cross-sectional size and a granular material size The cooling pipe 13 that matches and can accommodate the granular material passing through it, the middle part of the cooling pipe 13 is immersed in the cooling liquid of the box body, and the feeding port 16 and the discharge port 17 at both ends of the cooling pipe 13 are placed outside the box body 2, The feed inlet 16 of the cooling pipeline 13 is higher than the discharge outlet 17 of the cooling pipeline, so that the granular material slides from the cooling pipeline feed inlet 16 to the cooling pipeline discharge outlet 17 by its own gravity, and the particles pass through the flange 1 connected to the heating device. Enter the feed port 16 of the cool...

The invention relates to a quenching device, in particular to a quenching device of circular-section granular materials. The quenching device comprises a tank body containing a cooling liquid, a cooling duct, and a vibration mechanism for vibrating the cooling duct, wherein a cooling liquid inlet and a cooling liquid outlet are formed in the tank body; the size of the section of the quenching device is matched with that of each granular material; the cooling duct can allow the granular materials to pass through; the middle part of the cooling duct is soaked in the cooling liquid of the tank body; a feed port and a discharge port at the two ends of the cooling duct are formed outside the tank body; and the feed port of the cooling duct is higher than the discharge port of the cooling duct, so that the granular materials slide from the feed port of the cooling duct to the discharge port of the cooling duct by virtue of the gravity of each granular material. According to the quenching device of the circular-section granular materials, the cooling duct for allowing the particles to pass through is arranged in the tank body, so that cooling speeds of the particles are kept consistent, and the particles are cooled uniformly.
Description
technical field [0001] The invention relates to a quenching device, in particular to a quenching device for circular cross-section granular materials. Background technique [0002] Heat treatment is a metal thermal processing process in which metal materials are heated, kept warm, and cooled in a certain medium, and their properties are controlled by changing the metallographic structure on the surface or inside of the material. Widely used in machinery manufacturing, aerospace, rail transit and many other industries. Among them, the quenching process is a heat treatment method that rapidly cools the material to a certain temperature through a low-temperature medium after heating it to a certain temperature. Common cooling media include water, air, oil, etc., and cooling methods include spraying, immersion, etc. [0003] For the heat treatment of large and medium-sized workpieces, box furnaces, pit furnaces, mesh belt furnaces, vacuum furnaces, and salt bath furnaces are u...
