DETAILED DESCRIPTION

[0029] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0030] The utility model provides the following preferred embodiments:

[0031] Embodiment 1, as Figure 1-Figure 6 As shown, a batching device for an annealing furnace includes a stirring tank 11, a stirring mechanism and a pretreatment mechanism;

[0032] The stirring mechanism includes a rotating assembly and a plurality of stirring rods 14. The plurality of stirring rods 14 are all located inside the stirring tank 11. The rotating assembly is located between the stirring tank 11 and the plurality of stirring rods 14. When the rotating assembly is working, the plurality of stirring rods 14 can be driven to rotate to achieve stirring and mixing between the raw materials and water.

[0033] The pretreatment mechanism includes a pretreatment box 16, a rotating rod 19, two crushing rollers 18, a plurality of spiral blades 20, a transmission assembly and a driving assembly. The pretreatment box 16 is fixed to the top of the mixing tank 11, and the pretreatment box 16 and the mixing tank 11 are connected. Specifically, a valve for opening and closing is provided between the pretreatment box 16 and the mixing tank 11. The two crushing rollers 18 are symmetrically arranged in the interior of the pretreatment box 16. The rotating rod 19 is located in the middle below the two crushing rollers 18. Both ends of the rotating rod 19 are rotatably connected to the pretreatment box 16. The plurality of spiral blades 20 are equidistantly fixed to the surface of the rotating rod 19. The transmission assembly is located between the rotating rod 19 and the rotating assembly, and the driving assembly is located between the rotating rod 19 and the two crushing rollers 18.

[0034] When the rotating assembly is working, it can drive the rotating rod 19 to rotate through the transmission assembly. When the rotating rod 19 rotates, it can drive the two crushing rollers 18 to rotate through the driving assembly. The two crushing rollers 18 can be used to pre-treat the powder entering the pre-treatment box 16, crush the powder, and remove the agglomerates on the surface. At the same time, when the rotating rod 19 rotates, it can drive the spiral blades 20 to rotate, so as to achieve preliminary stirring and mixing of the crushed powder raw materials, so that the refractory aggregate, powder and binder form a mixture, which is convenient for subsequent mixing and stirring with water, which is beneficial to improving the mixing effect, and then beneficial to improving the quality of the refractory castable.

[0035] like Figure 1-Figure 6 As shown, the rotation directions of two adjacent spiral blades 20 are opposite, which is beneficial to improving the effect of preliminary mixing between powders. The inner walls on both sides of the pretreatment box 16 are provided with guide blocks to guide the powders.

[0036] like Figure 1-Figure 6 As shown, the rotating assembly includes a motor 12 and a stirring shaft 13, the stirring shaft 13 is rotatably arranged inside the stirring tank 11, a plurality of stirring rods 14 are equidistantly fixed on the surface of the stirring shaft 13, the motor 12 is fixedly installed on the top of the stirring tank 11, and the output end of the motor 12 is fixedly connected to the top of the stirring shaft 13;

[0037] When the multiple stirring rods 14 need to rotate, the motor 12 is controlled to work, and the motor 12 can drive the stirring shaft 13 to rotate, and then drive the multiple stirring rods 14 to rotate, thereby achieving a stirring effect and realizing uniform mixing between the powder mixture and water.

[0038] like Figure 1-Figure 6As shown, the transmission assembly includes a first bevel gear 25, a second bevel gear 27, a second driving wheel 28, a second driven wheel 29 and a second transmission belt 30;

[0039] One end of the rotating rod 19 passes through the pretreatment box 16 and is fixedly connected to the first bevel gear 25. A driving rod 26 is rotatably provided at the top of the stirring tank 11. A second bevel gear 27 is fixed to the top of the driving rod 26. The second bevel gear 27 and the first bevel gear 25 are meshed with each other. A second driven wheel 29 is located below the second bevel gear 27 and is fixed to the surface of the driving rod 26. A second driving wheel 28 is located above the stirring tank 11 and is fixed to the surface of the stirring shaft 13. A second transmission belt 30 is sleeved between the second driven wheel 29 and the second transmission belt 30.

[0040] When the stirring shaft 13 rotates, it can drive the second driving wheel 28 to rotate, and under the action of the second transmission belt 30, it can drive the second driven wheel 29 to rotate. The second driven wheel 29 can drive the second bevel gear 27 to rotate through the driving rod 26. Since the second bevel gear 27 and the first bevel gear 25 are meshed, when the second bevel gear 27 rotates, it can drive the first bevel gear 25 to rotate, and then the rotating rod 19 can drive the spiral blade 20 to rotate, thereby realizing the preliminary mixing of the powder inside the pretreatment box 16.

[0041] like Figure 1-Figure 6 As shown, the driving assembly includes a first driven wheel 23, a first transmission belt 24, a first driving wheel 22 and two spur gears 21. The two spur gears 21 are respectively fixed to one end of the two crushing rollers 18 away from the first bevel gear 25. The first driving wheel 22 is fixed to one end of the rotating rod 19 away from the first bevel gear 25. The first driven wheel 23 is fixed to the end of one of the crushing rollers 18. The first transmission belt 24 is sleeved on the first driven wheel 23 and the first driving wheel 22.

[0042] When the rotating rod 19 rotates, it can synchronously drive the first driving wheel 22 to rotate, and under the action of the first transmission belt 24, it can drive the first driven wheel 23 to rotate. The first driven wheel 23 can drive a spur gear 21 located on one side of the first driven wheel 23 to rotate. Since the two spur gears 21 are meshed with each other, when one spur gear 21 rotates, it can drive the other spur gear 21 to rotate in the opposite direction, thereby making the two crushing rollers 18 rotate in the opposite direction, thereby achieving the crushing of the powder, avoiding the phenomenon of agglomeration, and facilitating the initial uniform mixing of the powder.

[0043] like Figure 1-Figure 6 As shown, a plurality of feed ports 17 are equidistantly installed at the top of the pretreatment box 16, and a water inlet 15 is fixed at the top of the mixing tank 11. The setting of the water inlet 15 facilitates the addition of water into the interior of the mixing tank 11, and the setting of the feed port 17 facilitates the placement of powdered raw materials into the interior of the pretreatment box 16.
