[0014] By adopting the above technical solution, when the slag moves in the barrel, the upper stirring rods and the lower stirring rods can respectively drive the slag to turn over in the vertical direction, thereby improving the cooling effect of the air outlet pipe on the slag.

Detailed Embodiment

[0034] The following will Figure 1-2 further describe the present application in detail.

[0035] An embodiment of the present application discloses a cooling device for slag treatment. Referring to Figure 1 and Figure 2 , a cooling device for slag treatment includes a base 4, an air-cooling mechanism 1, a cooling mechanism 2 and a material receiving mechanism 3. The slag is poured into the air-cooling mechanism 1, and the slag enters the cooling mechanism 2 through the air-cooling mechanism 1 and finally falls into the material receiving mechanism 3. The air-cooling mechanism 1 is used for primary cooling of the slag, and the cooling mechanism 2 performs secondary cooling on the slag. The two complement each other, greatly improving the cooling efficiency of the slag.

[0036] The base 4 has a cuboid structure. On one side of the base 4, a plurality of support rods 41 are fixed. The plurality of support rods 41 are arranged in a rectangular array, and the air-cooling mechanism 1 is installed on the support rods 41. On the base 4, a plurality of fixing rods 42 are also fixedly installed. The plurality of fixing rods 42 are located on one side of the support rods 41, and the plurality of fixing rods 42 are also arranged in a rectangular array, and the lengths of the fixing rods 42 from the fixing rod 42 close to the support rods 41 to the fixing rod 42 far from the support rods 41 decrease in turn. The cooling mechanism 2 is fixedly installed on the fixing rods 42, so that the cooling mechanism 2 is inclined.

[0037] The air-cooling mechanism 1 includes a barrel 11. The barrel 11 is a cylindrical barrel with one end closed. The circumferential surface of the barrel 11 is welded and fixed to the end of the support rod 41 away from the base 4, and the closed end of the barrel 11 is set away from the fixing rod 42. A filling port 111 is opened on the circumferential surface of the barrel 11. The filling port 111 is opened near the closed end of the barrel 11, and the filling port 111 faces away from the base 4. Through the filling port 111, it is convenient to add slag into the barrel 11.

[0038] A driving component 12 is arranged in the barrel 11. The driving component 12 includes a rotating rod 121. The rotating rod 121 is arranged in the barrel 11. The axis of the rotating rod 121 coincides with the axis of the barrel 11, and one end of the rotating rod 121 extends out of the closed end of the barrel 11. A spiral blade 122 is fixedly sleeved on the rotating rod 121. The spiral blade 122 is arranged along the entire length of the rotating rod 121, and the spiral blade 122 is inclined towards the open end of the barrel 11. When the rotating rod 121 rotates, the spiral blade 122 can drive the slag added into the barrel 11 to move towards the open end of the barrel 11.

[0039] A plurality of ribs 1221 are also machined on the surface of the spiral blade 122. The ribs 1221 are arranged along the entire width direction of the spiral blade 122. When the spiral blade 122 rotates, the ribs 1221 can drive the slag to turn over, thereby improving the dissipation of heat inside the slag and improving the cooling effect on the slag.

[0040] An installation rod 43 is also fixedly connected to the base 4. A motor 1211 is fixedly connected to the end of the installation rod 43 away from the base 4. The output shaft of the motor 1211 is fixedly connected to the end of the rotating rod 121 extending out of the barrel 11. When the motor 1211 is turned on, the motor 1211 can drive the rotating rod 121 to rotate.

[0041] A plurality of air outlet pipes 13 are arranged through the barrel 11. The air outlet pipes 13 are arranged at equal intervals along the length direction of the barrel 11, and the air outlet pipes 13 face away from the base 4, so as to prevent the slag in the barrel 11 from entering the air outlet pipes 13 and blocking the air outlet pipes 13. The end of the air outlet pipe 13 away from the barrel 11 is connected to a blower. The blower can blow out cold air, and the cold air is blown into the barrel 11 through the air outlet pipes 13 to air-cool the slag in the barrel 11.

[0042] A plurality of lower stirring rods 14 are installed in the barrel 11. The lower stirring rods 14 are arranged on the inner wall of the barrel 11 close to the base 4, and the lower stirring rods 14 extend out of the barrel 11. A driving motor (not shown in the figure) is connected to one end of the lower stirring rods 14 extending out of the barrel 11. The driving motor drives the lower stirring rods 14 to rotate. A stirring blade 16 is fixedly sleeved on the lower stirring rods 14, and the stirring blade 16 is inclined in the direction away from the base 4, so that when the lower stirring rod 14 rotates, the slag can be lifted up and turned over, thereby improving the cooling effect of the slag.

[0043] A plurality of upper stirring rods 15 are also installed in the barrel 11. The upper stirring rods 15 are arranged on the inner wall of the barrel 11 away from the base 4, and the upper stirring rods 15 and the lower stirring rods 14 are staggered. The installation method of the upper stirring rods 15 is the same as that of the lower stirring rods 14, and stirring blades 16 are also fixedly sleeved on the upper stirring rods 15. The stirring blades 16 on the upper stirring rods 15 and the stirring blades 16 on the lower stirring rods 14 have the same inclination direction. When the upper stirring rods 15 rotate, the slag can be brought upward, thereby stirring the slag and improving the air cooling effect of the air outlet pipe 13 on the slag.

[0044] When the upper stirring rod 15 and the lower stirring rod 14 rotate, the upper stirring rod 15 and the lower stirring rod 14 simultaneously turn over the slag to allow the cold air inside the slag to dissipate, and the cold air inside the slag to dissipate, and the cold air is blown dry through the air outlet pipe 13 to avoid the generation of water vapor after the slag enters the cooling cylinder 21, thereby improving the cooling effect on the slag.

[0045] The cooling mechanism 2 includes a cooling cylinder 21, which is a cylindrical structure with both ends open. The outer peripheral surface of the cooling cylinder 21 is fixedly welded to the fixing rod 42. Since the length of the fixing rod 42 decreases from close to the support rod 41 to away from the support rod 41, the cooling cylinder 21 is arranged at an angle, and the end of the cooling cylinder 21 close to the barrel 11 is arranged on the side of the barrel 11 close to the base 4, so that the slag in the barrel 11 can fall into the cooling cylinder 21.

[0046] A water storage chamber 211 is provided in the outer peripheral wall of the cooling cylinder 21, and cooling water is filled in the water storage chamber 211, and the cooling water is used to cool the slag entering the cooling cylinder 21. The cooling cylinder 21 is also connected to a cooling water circulation system (not shown in the figure), and the cooling water circulation system can circulate the cooling water in the water storage chamber 211, maintain the cooling water temperature in the water storage chamber 211, and thus ensure the cooling effect of the cooling water on the slag.

[0047] A blowing cylinder 22 is passed through the cooling cylinder 21. The blowing cylinder 22 is coaxially arranged with the cooling cylinder 21, and a space for the slag to pass through is reserved between the blowing cylinder 22 and the cooling cylinder 21. A plurality of connecting rods 24 are fixedly connected between the outside of the blowing cylinder 22 and the inner wall of the cooling cylinder 21, and the connecting rods 24 fixedly connect the blowing cylinder 22 and the cooling cylinder 21.

[0048] An air inlet pipe 23 is connected to the end of the blow tube 22 away from the air cooling mechanism 1, and an air supply fan (not shown in the figure) is connected to the end of the air inlet pipe 23 away from the blow tube 22. When the air supply fan is turned on, cold air is blown into the blow tube 22. A plurality of air outlet holes 221 are provided on the outer wall of the blow tube 22, and the air outlet holes 221 are distributed all over the outer wall of the blow tube 22. The cold air in the blow tube 22 is blown out through the blowing air, so that the slag entered into the cooling tube 21 is blown onto the inner wall of the cooling tube 21, so that the cooling water can have a better cooling effect on the slag, and the cold air blown out of the blow tube 22 can also cool the slag.

[0049] Furthermore, the air outlet hole 221 is opened at an angle, and the air outlet hole 221 is set to be inclined away from the air cooling mechanism 1, so that the wind blown out through the air outlet hole 221 will blow the slag in the cooling cylinder 21 to the end of the cooling cylinder 21 away from the barrel 11, which makes it easier for the slag to be discharged from the cooling cylinder 21. Moreover, the air outlet hole 221 is opened at an angle, which can prevent the slag from entering the blowing cylinder 22 through the air outlet hole 221.

[0050] A diverter cover 222 is fixed at one end of the blowing tube 22 close to the barrel 11. The diverter cover 222 is a conical structure. The circular bottom surface of the diverter cover 222 is welded and fixed to the end surface of the blowing tube 22 close to the barrel 11, and the tip of the diverter cover 222 extends from the end of the cooling tube 21 close to the barrel 11; the diverter cover 222 can guide the slag discharged from the barrel 11 into the cooling tube 21, so that the slag is evenly discharged into the cooling tube 21, thereby improving the cooling effect of the cooling tube 21 on the slag.

[0051] The material collecting mechanism 3 includes a hopper 31 , which is a rectangular structure with one side open. The hopper 31 is arranged below the end of the cooling cylinder 21 away from the cylinder 11 , and the hopper 31 is located on one side of the base 4 , so that the slag falling through the cooling cylinder 21 can fall into the hopper 31 .

[0052] Lifting ears 32 are fixedly provided on the opposite sides of the hopper 31, and the hopper 31 can be lifted up through the lifting ears 32 to facilitate the pouring out of the slag collected in the hopper 31; moving wheels 33 are fixedly installed at the four corners of the hopper 31 away from the cooling cylinder 21, and the moving wheels 33 can be universal wheels with braking function. By setting the moving wheels 33, the hopper 31 can be moved easily.

[0053] The implementation principle of a cooling device for slag treatment in an embodiment of the present application is as follows: The slag to be treated is poured into the barrel 11 through the filling port 111. The driving assembly drives the slag to move in the barrel 11. The air outlet pipe 13 blows out cold air to air-cool the slag. Moreover, the rotation of the upper stirring rod 15 and the lower stirring rod 14 can turn the slag, improving the cooling effect on the slag. After the slag is air-cooled in the barrel 11, it enters the cooling cylinder 21. The cooling water in the inner wall of the cooling cylinder 21 can perform secondary cooling on the slag. The cold air blown out from the air blowing cylinder 22 can further cool the slag. Moreover, the air blowing cylinder 22 can blow the slag towards the inner wall of the cooling cylinder 21, greatly improving the cooling effect of the cooling cylinder 21 on the slag.
