Description

Technical Field

[0001] This utility model relates to the technical field of nut processing equipment, and more specifically, to a quenching and cooling device for nut production. Background Technology

[0002] Quenching is a heat treatment process in which steel is heated to above the critical temperature, held at that temperature for a certain time, and then cooled at a rate greater than the critical cooling rate to obtain a non-equilibrium structure dominated by martensite. In the production of nuts, quenching is required to significantly improve the strength, hardness, wear resistance, fatigue strength, and toughness of the nuts.

[0003] In the existing technology, when quenching nuts, the nuts are generally placed directly into the quenching tank for cooling. Prolonged use will increase the temperature of the coolant in the cooling tank, causing inconvenience for subsequent quenching. At the same time, a large amount of fumes will be generated during quenching, and the direct emission of these fumes will cause environmental pollution. Utility Model Content

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] This utility model provides, for example Figure 1-4 The quenching and cooling device for nut production shown includes a quenching pool 1 containing quenching liquid. A heat exchange device is connected to the lower end of the quenching pool 1 to cool the quenching liquid. A cover 2 is installed on the upper end of the quenching pool 1, and a feeding channel 3 is installed on the upper end of the cover 2. A holding box 4 is placed in the feeding channel 3, with a feeding port 5 at the upper end of the holding box 4. A liquid permeation hole 6 is opened on the side surface of the holding box 4.

A sealing ring 9 is installed on the upper end of the holding box 4. An exhaust fan 10 is installed on the cover 2 to extract waste gas from the quenching pool 1.

[0021] The quenching process of this device for nuts is as follows: Under normal conditions, the movable gate 8 is in the open state, and the lifting frame 7 lifts the holding box 4 to prevent the holding box from being immersed in the quenching liquid. The worker puts the heated nuts into the holding box 4 through the feed port 5, and then closes the movable gate 8. The lifting frame 7 moves the holding box 4 downward, allowing the nuts in the holding box 4 to be immersed in the quenching liquid. The sealing ring 9 can prevent the leakage of fumes generated during quenching. The exhaust fan 10 is started to extract the waste gas generated in the quenching pool 1. A purifier is connected to the outside of the exhaust fan 10 to facilitate the collection and purification of waste gas and prevent waste gas leakage from polluting the environment. After quenching is completed, the holding box 4 is lifted by the lifting frame 7, and then the nuts are taken out. When the temperature of the quenching liquid rises, the quenching liquid can be cooled by the heat exchange device.

[0022] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3 The lifting frame 7 includes an L-shaped support plate 11 installed on the upper end of the cover 2.

[0023] The process of the lifting frame 7 moving the container 4 is as follows: Start the servo motor 12 to rotate forward, the servo motor 12 can drive the take-up reel 13 to rotate forward, and then release the connecting rope 14. Then, under the action of gravity, the container 4 moves downward. Start the servo motor 12 to rotate in reverse, the servo motor 12 can drive the take-up reel 13 to rotate in reverse, and then the connecting rope 14 can be taken up. Then the container 4 can be pulled up by the U-shaped handle 15.

After the nut is quenched, the holding box 4 is pulled upward by the lifting frame 7, and the discharge port 20 is moved to the discharge channel 21. Then, under the action of the inclined surface of the inclined baffle 19, the nut can be discharged from the inclined baffle 19 and the discharge channel 21. When the holding box 4 moves into the quenching liquid, the limiting frame 22 can limit the holding box 4, and the intercepting plate 23 can intercept the discharge port 20 to prevent the nut from falling.
