A refractory brick unloading chute

Abstract

This utility model provides a refractory brick unloading chute, relating to the field of refractory material applications. It includes a base, a guide rod, a rotating frame, and rotating rollers. A guide rod is fixedly connected to one side of the top of the base, and a rotating frame is located on one side of the guide rod. Multiple rotating rollers are equidistantly connected inside the rotating frame. An angle adjustment mechanism is symmetrically located on the top of each rotating roller, and the angle adjustment mechanism is connected to a material support rod. This utility model loosens the fixing sleeve outside the locking bolt, so the fixing sleeve no longer clamps the connecting section to one end of the material support rod. The material support rod can rotate freely around its rotation axis, thereby changing the tilt angle of the rotating frame after the material support rod overlaps at the brick kiln outlet. Then, the fixing sleeve is tightened to re-clamp and lock the connecting section and the material support rod in place, thus changing the overall tilt angle of the chute. This avoids the problem of the chute tilt angle being less than the natural angle of accumulation of the material, which can easily cause refractory bricks to accumulate and clog the chute, making transportation inconvenient.

Description

Technical Field

[0001] This utility model relates to the field of refractory material application technology, and in particular to a refractory brick unloading chute. Background Technology

[0002] The refractory brick unloading chute is a conveying device specifically designed for handling refractory bricks. It adopts an inclined chute structure and uses gravity to achieve a smooth descent of the bricks. Its surface is covered with a wear-resistant and high-temperature resistant coating to reduce transportation friction and damage. The bottom is equipped with a buffer device to reduce impact force. This equipment is suitable for refractory material installation projects in industrial kilns such as blast furnaces and hot blast stoves. It can significantly improve brick unloading efficiency and ensure the integrity of the bricks. It is a key auxiliary equipment in the application of refractory materials.

[0003] When unloading refractory bricks from a fired cement kiln, the distance between the kiln car and the unloading point is relatively far, requiring two people to work together. The conveyor belt does not extend directly to the kiln car loaded with refractory bricks. If the inclination angle of the chute is less than the natural angle of accumulation of the material, the refractory bricks are prone to accumulate and blockage in the chute, making it inconvenient to transport them. Therefore, this utility model proposes a refractory brick unloading chute to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this utility model proposes a refractory brick unloading chute to solve the issue in the prior art where, if the chute's inclination angle is less than the material's natural angle of repose, refractory bricks easily accumulate and clog within the chute, making transportation inconvenient.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a refractory brick unloading chute, including a base, a guide rod, a rotating frame and rotating rollers. The guide rod is fixedly connected to one side of the top of the base, and a rotating frame is provided on one side of the guide rod. Multiple rotating rollers are equidistantly rotatably connected inside the rotating frame. An angle adjustment mechanism is symmetrically provided on the top of the rotating rollers, and the angle adjustment mechanism is connected to a material support rod.

[0006] A further improvement is that the angle adjustment mechanism includes a connecting section, an arc groove, a rotating shaft, a locking bolt, and a fixing sleeve. The two sides of the top of the rotating frame are symmetrically fixedly connected to the connecting sections. One side of the connecting section is hinged to one end of the material support rod through the rotating shaft. One end of the material support rod is fixedly connected to the locking bolt. One end of the locking bolt passes through the interior of the arc groove and is threadedly connected to the fixing sleeve.

[0007] A further improvement is that the material support rod is designed as a hollow rectangular structure, and a reinforcing rod is fixedly connected between the two material support rods. One end of the material support rod overlaps on one side of the brick kiln outlet.

[0008] A further improvement is that the diameter of the fixing sleeve is larger than the width of the arc groove, and multiple strip blocks are fixedly connected to the outer side of the fixing sleeve.

[0009] A further improvement is that the outer side of the roller is reinforced with flat steel and angle steel, and the outer side of the roller is coated with a high-polymer wear-resistant coating.

[0010] A further improvement is that hinge blocks are symmetrically fixedly connected to both sides of the bottom of the rotating frame, and sleeves are fixedly connected inside the hinge blocks. The hinge blocks are slidably connected to the guide rods through the sleeves.

[0011] A further improvement is that a support block is fixedly connected to the top of the base away from the guide rod. The support block is T-shaped, and the bottom of the rotating frame fits against the top of the support block.

[0012] The beneficial effects of this utility model are as follows: by loosening the fixing sleeve on the outside of the locking bolt, the fixing sleeve no longer clamps the connecting section and one end of the material support rod, allowing the material support rod to rotate freely around the rotation axis. This changes the tilt angle of the rotating frame after the material support rod is attached to the brick kiln outlet. Then, the fixing sleeve is tightened to re-clamp and lock the connecting section and the material support rod in place, thereby changing the tilt angle of the entire chute. This avoids the problem that the tilt angle of the chute is less than the natural angle of accumulation of the material, which would cause refractory bricks to accumulate and clog in the chute, making transportation inconvenient.

Detailed Implementation

[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1 , 2As shown in Figure 3, this embodiment proposes a refractory brick unloading chute, including a base 1, a guide rod 2, a rotating frame 3, and rotating rollers 4. The guide rod 2 is fixedly connected to one side of the top of the base 1, and the rotating frame 3 is provided on one side of the guide rod 2. Multiple rotating rollers 4 are equidistantly rotatably connected inside the rotating frame 3. An angle adjustment mechanism is symmetrically provided on the top of the rotating rollers 4, and the angle adjustment mechanism is connected to a material support rod 6. The rotating frame 3 and the rotating rollers 4 are combined to form a chute. In use, the rotating frame 3 is moved along the outside of the guide rod 2 to the side close to the conveyor belt for external transport. The bottom end of the rotating frame 3 rotates towards the converter with the center of the guide rod 2, and the angle of the material support rod 6 is adjusted by the angle adjustment mechanism so that one end of it overlaps the side of the brick kiln outlet. At this time, the top end of the rotating frame 3 extends into the brick kiln outlet. People hold the refractory bricks on the rotating rollers 4 inside the rotating frame 3 and the refractory bricks automatically roll to the conveyor belt. The rotating rollers 4 can reduce the friction generated when transporting refractory bricks, making the transport of refractory bricks more convenient.

[0019] The angle adjustment mechanism includes a connecting section 5, an arc-shaped groove 8, a rotating shaft 9, a locking bolt 10, and a fixing sleeve 11. Connecting sections 5 are symmetrically fixedly connected to both sides of the top of the rotating frame 3. One side of the connecting section 5 is hinged to one end of the material support rod 6 via the rotating shaft 9. A locking bolt 10 is fixedly connected to one end of the material support rod 6. One end of the locking bolt 10 passes through the arc-shaped groove 8 and is threadedly connected to the fixing sleeve 11. The material support rod 6 is a hollow rectangular structure. A reinforcing rod 7 is fixedly connected between two material support rods 6. One end of the material support rod 6 overlaps on one side of the brick kiln outlet. The diameter of the fixing sleeve 11 is... The size is larger than the width of the arc groove 8. Multiple strip blocks are fixedly connected to the outside of the fixing sleeve 11. Loosen the fixing sleeve 11 on the outside of the locking bolt 10. The fixing sleeve 11 no longer clamps the connecting section 5 and one end of the material support rod 6. The material support rod 6 can rotate freely with the rotation shaft 9 as the center. This changes the tilt angle of the rotating frame 3 after the material support rod 6 overlaps at the brick kiln outlet, thereby changing the tilt angle of the entire chute. This avoids the problem that the tilt angle of the chute is less than the natural accumulation angle of the material, which makes it easy for refractory bricks to accumulate and block in the chute, making it inconvenient to transport. Then tighten the fixing sleeve 11 so that it re-clamps and locks the connecting section 5 and the material support rod 6 in the same position.

[0020] The outer side of the roller 4 is reinforced with flat steel and angle steel, and the outer side of the roller 4 is coated with a polymer wear-resistant coating to increase the wear resistance of the chute and extend its service life.

[0021] The bottom of the rotating frame 3 is symmetrically fixedly connected to two sides of the hinge block 12. The inside of the hinge block 12 is fixedly connected to the sleeve 13. The hinge block 12 is slidably connected to the guide rod 2 through the sleeve 13. The bottom end of the rotating frame 3 moves linearly back and forth on the outside of the guide rod 2 through the sleeve 13 to move the rotating frame 3 to the side adjacent to the conveyor belt, or to push the rotating frame 3 to reset.

[0022] A support block 14 is fixedly connected to the top of the base 1 away from the guide rod 2. The support block 14 is T-shaped. The bottom of the rotating frame 3 fits against the top of the support block 14. After finishing the work, loosen the fixing sleeve 11 again, rotate the material support rod 6 to approach one side of the rotating frame 3, then tighten the fixing sleeve 11 to lock the position, rotate the rotating frame 3 upward so that its bottom sits on the top of the support block 14. The support block 14 supports the rotating frame 3, reducing the area occupied by the rotating frame 3 and the material support rod 6, so as to store the rotating frame 3 and the material support rod 6.

[0023] The refractory brick unloading chute loosens the fixing sleeve 11 on the outside of the locking bolt 10. The fixing sleeve 11 no longer clamps the connecting section 5 and one end of the material support rod 6. The material support rod 6 can rotate freely with the rotation shaft 9 as the center. This changes the tilt angle of the rotating frame 3 after the material support rod 6 overlaps at the brick kiln outlet. Then, the fixing sleeve 11 is tightened to re-clamp and lock the connecting section 5 and the material support rod 6 in the locked position. This changes the tilt angle of the entire chute, preventing the refractory bricks from accumulating and clogging in the chute when the tilt angle of the chute is less than the natural angle of accumulation of the material, which would make transportation inconvenient.
