Description

Technical Field

[0001] This utility model relates to the field of spiral feeding technology, specifically a multi-layer heterogeneous spiral feeding device. Background Technology

[0002] A coke oven is a furnace used to refine coke; a screw feeder is a continuous conveying device that uses the rotation of screw blades to push materials, widely used in chemical, building materials, metallurgy, and grain industries. The working principle of a screw feeder is relatively simple, mainly relying on the rotation of screw blades to push materials. When the motor drives the screw shaft to rotate, the material on the screw blades is subjected to centrifugal force and friction, moving forward with the rotation of the screw blades, thus achieving continuous material conveying. In the coking industry, the multi-layer heterogeneous screw feeder is a specialized device designed specifically for coke oven coal conveying. Its core function is to achieve efficient, uniform, and quantitative feeding of bulk materials such as coal through the synergistic effect of the multi-layer screw structure. This device combines the continuous conveying characteristics of screw feeding technology with the special requirements of coke oven processes, becoming one of the key pieces of equipment in modern coking plants.

[0003] However, in the common coking process, materials are usually conveyed by screw feeders. However, some coal materials are in the form of lumps and others are in the form of wet powder. When conveying coal materials through a single screw feeder, it is not convenient to convey different types of coal materials, which can lead to blockage of the screw feeder. Therefore, there is still room for further improvement.

[0004] Therefore, we propose a multi-layer heterogeneous screw feeder to solve the problems mentioned above. Utility Model Content

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-6 As shown, the present invention provides a technical solution: a multi-layer heterogeneous spiral feeding device, comprising: a base plate 1, a moving wheel 2, a threaded rod 3, a connecting plate 4, an anti-slip seat 5, a limiting rod 6, a support plate 7, a first spiral conveyor 8, a shaftless spiral rod 9, a first discharge port 10, a conveying pipe 11, a support rod 12, a baffle 13, a slag discharge port 14, a pull rod 15, a limiting disc 16, a spring 17, a second spiral conveyor 18, and a second discharge port 19.

[0034] In the coking process, coke ovens typically use screw feeders to transport materials. However, coal can be in various forms, such as lumps or moist powder. Using a single screw feeder is not convenient for transporting different types of coal and can lead to blockages in the screw feeder. Therefore, there is room for further improvement.

[0035] like Figure 1 and Figure 2 As shown, the lower side of the base plate 1 is provided with movable wheels 2, which are arranged in an array. The base plate 1 is threadedly connected to the threaded rod 3, which is rotatably connected to the connecting plate 4. The lower side of the connecting plate 4 is provided with anti-slip seats 5, which are arranged in an array. The upper side of the connecting plate 4 is provided with a limit rod 6, which is symmetrical about the vertical central axis of the connecting plate 4. The limit rod 6 is slidably connected to the base plate 1. The movement and stopping of the device can be controlled by the cooperation of the movable wheels 2 and the anti-slip seats 5.

[0036] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, a support plate 7 is provided on the upper side of the base plate 1. The support plate 7 is fixedly connected to the first screw conveyor 8 through a connecting frame. The first screw conveyor 8 has a shaftless screw rod 9 inside. The shaftless screw rod 9 is symmetrical about the vertical central axis of the first screw conveyor 8. A first discharge port 10 is provided on the lower side of the first screw conveyor 8. The conveying pipe 11 is fixedly connected to the support plate 7 through the connecting frame. The rear side of the conveying pipe 11 is fixedly connected to the second screw conveyor 18. A second discharge port 19 is provided on the lower side of the second screw conveyor 18. Different types of coal can be conveyed through the first screw conveyor 8 and the second screw conveyor 18, which not only prevents blockage but also enhances the conveying efficiency.

[0037] like Figure 4 and Figure 5 As shown, the conveying pipe 11 is fixedly connected to the upper side of the first screw conveyor 8. A support rod 12 is provided on the left side inside the conveying pipe 11. The support rod 12 is symmetrical about the vertical central axis of the conveying pipe 11. A slag discharge port 14 is opened on the front side of the support rod 12. A baffle 13 is slidably connected to the upper side of the support rod 12. The baffle 13 is tightly fitted with the slag discharge port 14. A pull rod 15 is slidably connected to the front side of the conveying pipe 11. A limit plate 16 is provided on the lower side of the outside of the pull rod 15. The limit plate 16 is tightly fitted with the baffle 13. A spring 17 is provided on the outside of the pull rod 15. When it is necessary to convey different types of coal and change the baffle 13, the coal is controlled to be conveyed into the first screw conveyor 8 or the second screw conveyor 18.

[0038] like Figure 1 and Figure 2 As shown, when this device is needed to transport coal to the coke oven, the device can be moved by pushing the bottom plate 1, as the bottom plate 1 is equipped with moving wheels 2. After moving to a suitable position, the threaded rod 3 is rotated. Since the threaded rod 3 is rotatably connected to the connecting plate 4, and the upper side of the connecting plate 4 is equipped with a limit rod 6, rotating the threaded rod 3 can move the connecting plate 4 downward. The limit rod 6 is slidably connected to the bottom plate 1, so the limit rod 6 plays a limiting role on the connecting plate 4, which facilitates the vertical up and down movement of the connecting plate 4. When the lower side of the anti-slip seat 5 is tightly attached to the ground, the rotation of the threaded rod 3 is stopped, which increases the friction between the bottom plate 1 and the ground and prevents the device from moving when transporting coal.

[0039] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the first screw conveyor 8 is composed of a motor, a housing, and a shaftless screw rod 9. The shaftless screw rod 9 is symmetrical about the vertical central axis of the first screw conveyor 8. When the motor is started, the two shaftless screw rods 9 rotate in opposite directions, thus conveying the wet coal material, which is then discharged from the first discharge port 10. The second screw conveyor 18 is composed of a motor, a housing, and a shafted screw rod. Similarly, when the motor corresponding to the second screw conveyor 18 is started, the coal material is conveyed through the shafted screw rod and then discharged from the second discharge port 19. The first discharge port 10 and the second discharge port 19 are not on the same vertical line. When conveying different types of coal, the first screw conveyor 8 and the second screw conveyor 18 will not affect each other when operating separately. The first discharge port 10 prevents material from sticking to the conveyor rod, facilitating cleaning.

[0040] like Figure 3 , Figure 4 and Figure 5 As shown, a support rod 12 is provided inside the conveying pipe 11. When the baffle 13 is slidably connected to the conveying pipe 11 through the support rod 12, the lower side of the baffle 13 is tightly fitted with the upper side of the support rod 12. Regardless of whether the lower side of the baffle 13 is short or long, it can be slidably connected with the support rod 12, thereby facilitating the conveying of different types of coal. When the lower side of the baffle 13 is short, it can convey wet coal. The material conveyed from above the conveying pipe 11 will fall under the action of gravity and fall into the first screw conveyor 8. When the lower side of the baffle 13 is long, it can convey lumpy coal. The material conveyed from above the conveying pipe 11 will be conveyed into the second screw conveyor 18 due to the obstruction of the baffle 13, thereby facilitating the conveying of different types of coal and enhancing the feeding efficiency.

[0041] like Figure 4 and Figure 5 As shown, when the baffle 13 needs to be replaced, since the pull rod 15 is slidably connected to the conveying pipe 11, pulling the pull rod 15 upwards will disconnect the lower side of the pull rod 15 from the baffle 13, thus facilitating the removal of the baffle 13 from the inside of the conveying pipe 11 for replacement. The pull rod 15 acts as a limit for the baffle 13. In addition, a limit plate 16 is provided on the outside of the pull rod 15, which limits the spring 17. When the pull rod 15 moves upwards, the spring 17 will undergo elastic deformation. After the baffle 13 is replaced, the pull rod 15 is released, and the spring 17 will return to its elastic deformation, allowing the pull rod 15 to move downwards, preventing the baffle 13 from sliding out of the conveying pipe 11. When the coal comes into contact with the baffle 13, the support rod 12 and the pull rod 15 will apply force to the baffle 13, which can prevent the baffle 13 from disconnecting from the conveying pipe 11. In addition, a slag discharge port 14 is provided on the side of the conveying pipe 11 to facilitate cleaning of the inside of the conveying pipe 11.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
