[0028] In order to achieve the above objectives,
[0029] Reference Figure 1 The embodiments of this application provide a casting sand treatment cooling device, including a cooling container 1, an air cooling system 2, a water mist cooling system 3, a conveying system 4 and a stirring system 5 disposed in the cooling container 1;
[0030] The cooling container 1 is used to contain high-temperature casting sand; the air cooling system 2 is used to send outside air into the cooling container 1 to achieve a preliminary cooling effect; the water mist cooling system 3 is used to introduce coolant into the cooling container 1 to achieve a stronger cooling effect; the conveying system 4 allows the casting sand to move inside the cooling container 1, and the stirring system 5, in conjunction with the aforementioned air cooling system 2 and water mist cooling system 3, can agitate the sand particles to ensure uniform cooling. The combination of air cooling system 2 and water mist cooling system 3 can achieve efficient and uniform cooling.
[0031] The cooling container 1 has a feed inlet 11 at one end and a discharge outlet 12 at the other end. The conveying system 4 is located between the feed inlet 11 and the discharge outlet 12. The stirring system 5 is used in conjunction with the conveying system 4.
[0032] Optionally, the cooling container 1 in this embodiment can be a cylindrical structure lined with refractory bricks or ceramic fibers. It has a feed inlet 11 at the top and a discharge outlet 12 at the bottom. The feed inlet 11 is connected to a feeding conveyor, which can be a high-temperature resistant belt conveyor, to transport the high-temperature sand particles to the top of the cooling chamber. The discharge outlet 12 is connected to a discharge conveyor, which can be a screw conveyor, to discharge the cooled sand particles from the bottom of the cooling chamber. Tap water can be used as the coolant.
[0033] As an optional implementation, the air cooling system 2 of this embodiment includes a blower 21 and an air guide plate 22. The blower 21 is located outside the cooling container 1 and communicates with the cooling container 1. The air guide plate 22 is detachably installed inside the cooling container 1.
[0034] The blower 21 is connected to the bottom of the cooling container 1, and the top of the cooling container 1 is provided with an air inlet 23, so as to realize the flow of gas inside the cooling container 1 and achieve the initial reduction of sand temperature.
[0035] Optionally, the blower 21 in this embodiment has a plurality of air inlets 23, which are arranged around the axis of the cooling container 1 and inclined in the same direction. This achieves uniform air distribution and avoids cooling dead zones. The multiple air inlets 23 can be used in conjunction with the air guide plate 22 to ensure uniform airflow. An air distributor can be used to further ensure uniform air distribution and avoid cooling dead zones. The blower 21 is a high-pressure blower. The air inlets 23 can have their air speed and tilt angle adjusted by installing valves.
[0036] As an optional implementation, the cooling container 1 of this embodiment is provided with an air outlet 17 on the side away from the air inlet 23, and a cyclone separator 13, a bag filter 14 and an exhaust fan 15 are connected in series outside the air outlet 17.
[0037] Large dust particles are removed by a cyclone separator 13 installed at the air outlet 17 of the cooling container 1; fine dust is filtered by a bag filter 14. The purified air is discharged by an exhaust fan 15 to maintain negative pressure inside the cooling container 1 and prevent dust from overflowing.
[0038] As an optional implementation, the water mist cooling system 3 of this embodiment includes a water tank 31, a water pump 32, a water pipe 33, and a spray head 34. The spray head 34 is disposed in the cooling container 1, the water pump 32 is disposed in the water tank 31, one end of the water pipe 33 passes through the water tank 31 and is connected to the water pump 32, and the other end of the water pipe 33 is connected to the spray head 34.
[0039] By installing a spray head 34 on the top of the cooling container 1, water is atomized and sprayed evenly into the cooling chamber, further improving cooling efficiency. The spray head 34 can be a high-pressure atomizing nozzle.
[0040] Meanwhile, a drain plate 35 is provided at the outlet 12 of the cooling container 1. The coolant and sand are separated by the drain plate 35. The coolant enters the bottom of the cooling container 1 and can be connected to the water tank 31 through the return water pipe 3733 for reuse, thereby realizing the repeated use of water resources.
[0041] Furthermore, a water filter 36 can be connected in series on the return water pipe 3733 to filter the coolant and remove impurities, thus allowing the coolant to be reused multiple times, making it more energy-efficient and environmentally friendly. The water filter 36 can use a filter screen for filtration.
[0042] Optionally, the conveying system 4 in this embodiment includes a plurality of guide plates 41. The guide plates 41 are installed on the inner wall of the cooling container 1 and are inclined downwards. The plurality of guide plates 41 are arranged alternately. The alternate arrangement of the plurality of guide plates 41 divides the interior of the cooling container 1 into a serpentine channel. At the same time, the downward inclination of the guide plates 41 allows the sand particles to fall naturally under the action of gravity, increasing the distance that the sand particles travel in the cooling container 1.
[0043] It can also work in conjunction with air cooling system 2 and water mist cooling system 3 to further improve the cooling effect.
[0044] As an alternative implementation method, refer to Figure 2 The mixing system 5 in this embodiment includes a funnel 51, a stirring blade 52, and a drive device 53. The funnel 51 is located at the bottom of the cooling container 1, and its discharge end is connected to the discharge port 12. The stirring blade 52 is movably disposed within the funnel 51 and is connected to the drive device 53. The funnel 51 facilitates the falling of the moistened sand particles onto the drain plate 35. The stirring blade 52 simultaneously mixes the sand particles.
[0045] As an optional implementation, the discharge port 12 of this embodiment is provided with a temperature sensor 16, and a processor is provided on the outside of the cooling container 1. The temperature sensor 16 is electrically connected to the processor.
[0046] The temperature of the sand particles at the discharge port 12 can be monitored in real time by the temperature sensor 16. The air cooling system 2, water mist cooling system 3 and stirring system 5 can be adjusted by the processor to regulate the fan air volume, water spray volume and stirring speed.
[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application.
