[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Example:

[0021] Please see Figures 1-4 This utility model provides a technical solution: a high-efficiency cooling device for cast steel parts, including a base 1, a fixed frame 2 fixedly connected to the top of the base 1, a support plate 3 fixedly connected to the inner side wall of the fixed frame 2, a cooling mechanism provided on the support plate 3, a support leg 22 fixedly connected to the bottom of the base 1, a cooling box 12 fixedly connected to the top of the base 1, the cooling box 12 being located on the left side of the fixed frame 2, a ventilation slot 13 being provided on the right side wall of the cooling box 12, a clamping seat 15 being rotatably connected to the inner wall of the cooling box 12, a stepper motor 16 fixedly connected to the rear side wall of the cooling box 12, the output end of the stepper motor 16 being fixedly connected to the rear end of the clamping seat 15, and a coolant recovery mechanism being provided at the bottom of the base 1;

[0022] The cooling mechanism includes an air-cooled box 6, which is fixedly connected to the support plate 3. A circular opening is provided on the right side wall of the air-cooled box 6. An axial flow fan 7 is fixedly connected to the outer wall of the air-cooled box 6. The axial flow fan 7 is located inside the circular opening. Several guide plates 11 are provided on the left side wall of the air-cooled box 6.

[0023] A water pump 5 and a coolant storage tank 4 are fixedly connected to the top of the support plate 3. The input end of the water pump 5 is connected to the port of the coolant storage tank 4. A guide pipe 9 is fixedly connected to the output end of the water pump 5. A flow control valve is installed on the guide pipe 9. A spray head 10 is fixedly connected to the outer wall of the water pump 5. The spray head 10 is located inside the air-cooled box 6.

[0024] In this embodiment, when cooling the cast steel parts, the cast steel parts to be cooled are first placed on the clamping seat 15 inside the cooling box 12. The clamps on the clamping seat 15 are used to clamp the cast steel parts. According to the size, shape and cooling requirements of the cast steel parts, the spray flow rate of the coolant in the spray head 10 is adjusted by the flow control valve. Then, the water pump 5 is started so that the coolant in the coolant storage tank 4 is transported to the spray head 10 through the guide pipe 9. The spray head 10 atomizes the coolant. Then, the axial flow fan 7 is started simultaneously. The blown air guides the coolant through the guide plate 11 and sprays it evenly on the surface of the cast steel parts. The axial flow fan 7 accelerates the evaporation of the coolant on the surface of the cast steel parts and speeds up the cooling rate.

[0025] A temperature sensor 14 is fixedly connected to the inner wall of the cooling box 12. A box cover 21 is hinged to the top of the cooling box 12. A rectangular opening is opened on the inner wall of the box cover 21. An observation window 23 is fixedly connected to the inner side of the rectangular opening. The operator can observe the cooling status of the cast steel part at any time through the transparent observation window 23 on the top of the cooling box 12. When the cast steel part is cooled to a suitable temperature, the cooling mechanism is closed, the cast steel part is taken out, and the cooling operation is completed. During the cooling process, the temperature sensor 14 monitors the temperature inside the cooling box 12 in real time and transmits the temperature data to the controller. When the temperature is higher than the upper limit of the preset temperature range, the controller controls the water pump 5 to increase the coolant delivery volume and simultaneously increases the wind speed of the axial flow fan 7. When the temperature is lower than the lower limit of the preset temperature range, the controller controls the water pump 5 to reduce the coolant delivery volume and decrease the wind speed of the axial flow fan 7, thereby achieving precise temperature control of the cooling process of the cast steel part.

[0026] The coolant recovery mechanism includes a coolant purification tank 17 and a U-shaped clamp 18. The coolant purification tank 17 is fixedly connected to the bottom of the base 1 via the U-shaped clamp 18. A flow guide valve 19 is fixedly connected to the bottom of the coolant tank 12. The end of the flow guide valve 19 away from the coolant tank 12 passes through the base 1 and is connected to the coolant purification tank 17. A return pipe 20 is fixedly connected to the right end of the coolant purification tank 17. The end of the return pipe 20 away from the coolant purification tank 17 is connected to the input end of the water pump 5. The coolant sprayed on the surface of the cast steel part flows into the bottom of the coolant tank 12 through the flipping of the clamp seat 15. When the flow guide valve 19 is opened, the coolant enters the coolant purification tank 17 for purification. The purified coolant is stored back in the coolant storage tank 4 through the return pipe 20 and can be recycled.

[0027] The outer wall of the air-cooled box 6 is symmetrically connected with auxiliary connectors 8. The auxiliary connectors 8 are fixedly connected to the support plate 3 by bolts. The auxiliary connectors 8 improve the strength and stability of the air-cooled box 6 when it is installed on the support plate 3.

[0028] Working principle: In use, the cast steel part to be cooled is first placed on the clamping seat 15 inside the cooling box 12. The clamps on the clamping seat 15 hold the cast steel part. According to the size, shape and cooling requirements of the cast steel part, the spray flow rate of the coolant in the spray head 10 is adjusted by the flow control valve. Then, the water pump 5 is started, so that the coolant in the coolant storage tank 4 is transported to the spray head 10 through the guide pipe 9. The spray head 10 atomizes the coolant. Then, the axial flow fan 7 is started simultaneously. The blown air guides the coolant through the guide plate 11 and sprays it evenly on the surface of the cast steel part. The axial flow fan 7 accelerates the evaporation of the coolant on the surface of the cast steel part, thus speeding up the cooling rate. Personnel can observe the cooling status of the cast steel parts at any time through the transparent observation window 23 on the top of the cooling box 12. When the cast steel parts are cooled to a suitable temperature, the cooling mechanism is turned off, the cast steel parts are taken out, and the cooling operation is completed. During the cooling process, the temperature sensor 14 monitors the temperature inside the cooling box 12 in real time and transmits the temperature data to the controller. When the temperature is higher than the upper limit of the preset temperature range, the controller controls the water pump 5 to increase the coolant delivery volume and simultaneously increases the wind speed of the axial flow fan 7. When the temperature is lower than the lower limit of the preset temperature range, the controller controls the water pump 5 to reduce the coolant delivery volume and decrease the wind speed of the axial flow fan 7, thereby achieving precise temperature control of the casting steel parts cooling process.
