Description

Technical Field

[0001] This utility model belongs to the field of quenching processing technology, and in particular relates to a simple all-round spray quenching device. Background Technology

[0002] Quenching, as a core process for strengthening and modifying steel materials, commonly includes air quenching, water quenching, and oil quenching. Among these, large shaft parts, such as rotors and support rollers, primarily utilize spray quenching technology. Spray quenching is an advanced heat treatment process that achieves precise cooling through the synergistic effect of a gas-liquid two-phase medium. It is suitable for large forgings of different steel grades and diameters, and can simultaneously cool different parts of the forging.

[0003] Currently, spray quenching technology has been widely applied in heavy machinery, rail transportation, energy equipment, and other fields, becoming an important technical means for the heat treatment of large metal materials. However, several technical bottlenecks still need to be addressed. First, traditional spray quenching systems use a single nozzle array with fixed parameters, making it difficult to adapt to the curved surface structure of complex workpieces. Due to significant differences in cooling rates in different areas, uneven residual stress can easily occur inside the workpiece, leading to quality problems such as deformation and cracking. In addition, the atomization effect of the coolant is significantly affected by pressure fluctuations, and traditional open circulation systems cannot achieve dynamic flow compensation, resulting in a coolant utilization rate of less than 30%, which increases production costs and exacerbates the pressure on industrial wastewater treatment.

[0004] Chinese invention patent CN 118647736A discloses a system and method for automatic spray quenching. By arranging a robotic arm and thermocouples inside the quenching chamber, combined with temperature sensors, the surface temperature of the component is measured, and the quenching treatment method is adjusted in a timely manner based on the temperature difference between different parts of the component. Chinese utility model CN ​​211284451U discloses a rotating spray mechanism in a quenching system. By incorporating a suspension rod into the quenching system and improving the connection structure between the power chamber and the rotating disk, more nozzle devices can be mounted. Furthermore, the angle and height of the nozzles can be adjusted according to requirements, making it suitable for most parts. While these two patents improve the cooling uniformity and atomization stability of the spray quenching device, the added robotic arm and suspension rod structure increase the device cost, and the complex mechanical structure reduces the device's adaptability and increases the risk of device failure.

[0005] The spray quenching devices currently on the market have the following problems when used: Traditional spray quenching devices usually have a high failure rate after a period of use, and the connections between mechanical structures are complex, which can easily lead to high operating costs. The replacement of failed parts is also relatively complicated. Therefore, the assembly of spray quenching devices is inconvenient when in use. Utility Model Content

[0023] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a simple omnidirectional spray quenching device.

[0024] like Figure 1-3As shown, this utility model discloses a simple all-around spray quenching device, including a conveying structure 1, a spraying structure 2, a recovery component 6, and a water tank 7. The original water tank 7 allows for the pre-filling of sufficient water. The conveying structure 1 consists of two symmetrically distributed tracks, including a conveying track 11 and a turning support rail 13. The turning support rail 13 forms a 45-degree angle with the conveying track 11, and a switch structure 12 is installed between the turning support rail 13 and the conveying track 11. A transport vehicle 5 is mounted on the top of the conveying structure 1. By installing the conveying structure 1 and the design of the turning support rail 13 on the side of the conveying track 11, the placement angle of the components during quenching can be adjusted. The 45-degree angled placement design solves the problem that the sides of the components cannot directly contact the quenching liquid, increasing the contact area between the components and the quenching liquid, improving cooling efficiency, and reducing the difference in cooling rates between different parts of the components.

[0025] The spray structure 2 consists of multiple simple spray fans 3, including a fan base 21, a fan water tank 22, a motor bracket 23, a fan motor 24, and a water inlet pipe 25. The fan motor 24 is a high-power direct-drive variable frequency motor with remotely adjustable speed. The variable frequency motor is fixed on the motor bracket 23 and drives the spray fans 3 to rotate through the drive gear 27, the transmission gear 28, and the fan drive shaft 26. The surface of the fan water tank 22 is equipped with an infrared temperature sensor 29, and the fan water tank 22 is equipped with a submersible pump 4, which is connected to the water inlet pipe 25. Due to the installation of the spray structure 2, the coverage area of ​​the quenching liquid during quenching is effectively increased, the floating time of the quenching liquid around the parts is increased, the flow speed is accelerated, the temperature around the quenched parts is quickly reduced, and the quenching effect is improved.

[0026] The spray fan 3 includes a fan shaft 31, spray holes 32, spray blades 33, and nozzles 34. The fan shaft 31 has a cylindrical structure and a blade hole on the side of the fan. The blade hole is used to fix the spray blades 33. The side end of the spray blades 33 is connected to the fan motor 24 through the drive gear 27 and the transmission gear 28. The rear end of the fan motor 24 is equipped with a bearing, which is connected to the water inlet pipe 25. The spray holes 32 are equidistantly distributed on the side of the spray blades 33, with an interval of about 3 cm. The spray holes 32 are used to install the nozzles 34. Due to the installation of the spray fan 3, the design of the spray structure 2 can effectively increase the coverage of the quenching liquid during quenching, increase the floating time of the quenching liquid around the parts, accelerate the flow speed, quickly reduce the temperature around the quenched parts, and improve the quenching effect.

[0027] The recycling component 6 includes a guide channel 61, a water purification device 62, and a drain pipe 63. The guide channel 61 is distributed inside the conveyor track 11. The cross-section of the guide channel 61 is V-shaped, and there is a height difference between the two ends of the guide channel 61. The depth of the front end of the guide channel 61 is about 3cm, and the depth of the rear end of the guide channel 61 is about 6cm. The lower end of the guide channel 61 is connected to the water purification device 62, and the water purification device 62 is connected to the water storage tank 7 through the drain pipe 63. Due to the installation of the guide channel 61, the V-shaped cross-section and height difference design of the guide channel 61 facilitates the collection and reuse of quenching liquid, avoiding material waste.

[0028] The working principle of this simple all-around spray quenching device is as follows: When using the device, the device body needs to be inspected first. When the equipment is working, the parameters are initially set. According to the size of the quenching object and the required cooling rate, the position, angle and speed of the spray fan 3 are adjusted. It is also checked whether the quenching liquid in the fan water tank 22 meets the requirements. An appropriate quenching liquid is selected, and the water inlet pipe 25 is checked for unobstructedness. After the inspection is completed, the submersible pump 4 and the fan motor 24 are started. The submersible pump 4 pumps the quenching liquid into the water inlet pipe 25 and into the fan shaft 31. The fan motor 24 drives the fan drive shaft 26 and the spray fan 3 to rotate through the drive gear 27 and the transmission gear 28. After the quenching liquid is sprayed out through the nozzle 34, the part to be quenched is placed on the transport equipment car 5. The turnout structure 12 is adjusted. According to the set program, the transport equipment car 5 moves at a certain speed, from the conveyor rail to the steering support rail 13, and through the conveyor rail 11 and the steering support rail 13. Transport the quenching object to the quenching area. Adjust the position and angle of the spray fan 3 in a timely manner according to the data of the infrared temperature sensor 29. During the quenching process, the quenching liquid flows to the water purification equipment 62 under the action of the guide channel 61, and then enters the water storage tank 7 through the drain pipe 63. After the spray quenching and the adjustment of the spray fan 3 and the quenching components are completed, start the fan motor 24 to drive the spray fan 3 to rotate for quenching. Adjust the speed of the spray fan 3 in a timely manner according to the data of the infrared temperature sensor 29. When the component cools down to the set temperature, turn off the fan motor 24 and the submersible pump 4 to end the quenching and collect the quenching liquid filtered by the water purification equipment 62. This utility model of simple all-round spray quenching device can adjust the speed of each modular spray fan 3 individually according to the needs of the component to be quenched, effectively and accurately control the cooling rate. At the same time, the modular design simplifies the mechanical structure of the spray quenching system, reduces the cost of use, and facilitates the replacement of failed components.
