Description

Technical Field

[0001] This utility model relates to the field of refractory mixing technology, specifically a mixing mechanism for processing refractory castables. Background Technology

[0002] When casting refractory is cast, it is necessary to mix various aggregates and various binders into the refractory and then mix them evenly through a mixing device. However, agglomeration is easy to occur when mixing refractory, and the agglomerates need to be crushed during the mixing process.

[0003] Chinese Patent CN215353217U discloses a mixing device for refractory castables, including a mixing box, a mounting frame, and a first motor. The bottom of the mixing box is fixedly connected to the top of the mounting frame, and the bottom of the first motor is fixedly connected to the inner wall of the mounting frame. A rotating rod is fixedly connected to the output end of the first motor via a coupling. The top end of the rotating rod penetrates the mixing box and extends into its inner cavity. Mixing blades are fixedly connected to the surface of the rotating rod extending into the inner cavity of the mixing box. This invention relates to the field of castable technology. This refractory castable mixing device can effectively grind the castable before mixing, preventing clumping after mixing with adhesives and other materials. The amount of castable entering the mixing box can be controlled, further preventing clumping during mixing and ensuring overall mixing effect. It is easy for users to operate and has strong overall stability.

[0004] The aforementioned mixing device mixes the castable by pouring the mixed castable and adhesive into a mixing tank, then pouring the castable into a processing tank for grinding, and finally sending the castable back into the mixing tank to mix with the mixed castable and adhesive. This mixing method not only increases the number of steps, but also inevitably leads to clumping during mixing. Therefore, further optimization is needed in terms of mixing. Utility Model Content

[0005] To address the problems of numerous mixing steps and difficulty in preventing agglomeration in the aforementioned mixing devices for refractory castables, this application provides a mixing mechanism for refractory castable processing, employing the following technical solution:

[0006] A mixing mechanism for processing refractory castables includes a mixing tank with a lid installed at the upper end.

The stirring mechanism includes a rotating tube with multiple stirring rods on the outer side and a spiral rod for lifting the castable upwards on the inner side. Multiple discharge ports are opened on the outer surface of the rotating tube near the upper end, and a grinding disc for grinding multiple castables is fixed at the lower end of the rotating tube.

[0007] Optionally, a feeding port is provided on the upper surface of the can lid near the left side, and a bearing for mounting the upper end of the rotating tube is fixedly installed in the center of the can lid. Locking screws that are screwed onto the mixing tank are inserted on both the left and right sides of the can lid.

[0008] Optionally, the upper end of the rotating tube passes through the can cover and is fixed with a second gear, and a second drive motor is fixed on the right side of the second gear and fixed on the can cover. A second drive gear that meshes with the second gear is fixed on the output shaft of the second drive motor.

[0009] Optionally, the upper end of the rotating tube is closed, and a guide plate is fixed on the inner side of the rotating tube above the discharge port. The upper end of the screw rod passes through the top of the rotating tube and is fixed with a first gear. A first drive motor is fixed on the left side of the first gear and is fixed on the can cover. A first drive gear that meshes with the first gear is fixed on the output shaft of the first drive motor.

[0010] Optionally, the grinding disc is set to be conical, and multiple uniformly arranged second grinding teeth are fixed on the outer side of the grinding disc. A funnel-shaped collecting hopper is provided at the lower end of the mixing tank, and multiple uniformly arranged first grinding teeth are fixed on the inner surface of the collecting hopper.

[0011] Optionally, a horizontally rotatable baffle is provided at the lower opening of the mixing tank, and the left end of the baffle is rotatably connected to the mixing tank through a fixed column. A support ring is fixed on the outside of the mixing tank, and multiple support legs are fixed on the lower side of the support ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the rotation of the rotating tube causes the stirring rod to mix the casting material and adhesive. At the same time, the grinding disc grinds and pulverizes the casting material and adhesive. The ground and pulverized casting material and adhesive are then conveyed upward by the screw and discharged back into the mixing tank through the outlet for further mixing. The unground casting material and adhesive flow downward and are ground by the grinding disc, thus achieving cyclic mixing and grinding of the casting material and adhesive. This greatly simplifies the mixing process and ensures that the casting material mixture does not clump. Attached Figure Description

The stirring mechanism 2 includes a rotating tube 29, and multiple stirring rods 25 arranged on the outer side of the rotating tube 29. The rotation of the rotating tube 29 causes the stirring rods 25 to mix and stir the castable and the binder. A spiral rod 28 is arranged on the inner side of the rotating tube 29 to lift the castable upward. Multiple discharge ports 24 are opened on the outer surface of the rotating tube 29 near the upper end, and a grinding disc 27 for grinding multiple castables is fixed at the lower end of the rotating tube 29. The grinding disc 27 is conical, and multiple uniform grinding plates are fixed on the outer surface of the grinding disc 27. The mixing tank 1 has a funnel-shaped collection hopper 13 at the lower end of the mixing tank 1 with evenly arranged second grinding teeth 26. The inner surface of the collection hopper 13 is fixed with multiple evenly arranged first grinding teeth 16. The grinding disc 27 rotates continuously, so that the second grinding teeth 26 and the first grinding teeth 16 grind and cooperate to achieve the crushing and grinding of the casting material and adhesive. The casting material and adhesive are crushed and ground by the grinding disc 27. The crushed casting material and adhesive are conveyed upward by the screw 28 and discharged back into the mixing tank 1 through the discharge port 24 for mixing. The unground casting material and adhesive flow downward and are ground by the grinding disc 27, thereby achieving the cyclic mixing and grinding of the casting material and adhesive.

[0022] Please refer to the details. Figure 2 As shown, a feeding port 33 is provided on the upper surface of the can lid 3 near the left side. The feeding port 33 is used to add raw materials. A bearing 31 is fixedly installed in the center of the can lid 3 to fit the upper end of the rotating tube 29. The bearing 31 rotates the rotating tube 29. Locking screws 32 are inserted on both the left and right sides of the can lid 3 and screwed onto the mixing tank 1. The can lid 3 is locked and fixed by the locking screws 32.

A second drive motor 5 is fixed on the can lid 3 on the right side of the second gear 22. A second drive gear that meshes with the second gear 22 is fixed on the output shaft of the second drive motor 5. The second drive motor 5 drives the second gear 22 to rotate, thereby driving the rotating tube 29 to rotate. The rotating tube 29 then drives the stirring rod 25 to mix and stir.

[0024] Please refer to the details. Figure 3As shown, the upper end of the rotating tube 29 is closed, and a guide plate 23 is fixed on the inner side of the rotating tube 29 above the discharge port 24. The guide plate 23 blocks the lifted casting material and adhesive, causing them to be discharged through the discharge port 24. The upper end of the screw rod 28 passes through the top of the rotating tube 29 and is fixed with a first gear 21. A first drive motor 4 is fixed on the left side of the first gear 21 and is fixed on the can cover 3. A first drive gear that meshes with the first gear 21 is fixed on the output shaft of the first drive motor 4. The first drive motor 4 drives the first gear 21 to rotate, thereby driving the screw rod 28 to rotate. The rotating screw rod 28 lifts the casting material and adhesive.

[0025] Please refer to the details. Figure 4 As shown, a horizontally rotatable baffle 15 is provided at the lower opening of the mixing tank 1, and the left end of the baffle 15 is rotatably connected to the mixing tank 1 via a fixed column 14. By rotating the baffle 15, the sealing of the opening is released, thereby realizing material discharge. A support ring 11 is fixed on the outside of the mixing tank 1, and multiple support legs 12 are fixed on the lower side of the support ring 11. The support legs 12 and the support ring 11 support the mixing tank 1.

[0026] Working principle: The casting material and adhesive are poured into the mixing tank 1 through the feeding port 33. At this time, the second drive motor 5 drives the second gear 22 to rotate, which in turn drives the rotating tube 29 to rotate. The rotating tube 29 drives the stirring rod 25 to mix and stir. When the rotating tube 29 is mixing and stirring, it drives the grinding disc 27 to rotate continuously to crush and grind the downward flowing casting material and adhesive. At this time, the first drive motor 4 drives the first gear 21 to rotate, which in turn drives the screw rod 28 to rotate. The rotating screw rod 28 lifts the crushed casting material and adhesive and sends it back to the mixing tank 1 through the discharge port 24 for further mixing and stirring, thereby completing the mixing process of the casting material and adhesive.
