Description

Technical Field

[0001] The utility model relates to the technical field of coke batching in a micro-positive pressure vertical kiln batching system, in particular to a vertical kiln coke batching structure. Background Art

[0002] The batching process of large-scale mixed-material mechanized vertical kiln requires adding limestone and coke into limestone weighing hopper and coke weighing hopper respectively. The weighed limestone and coke enter the upper hopper through the mixed material chute. After the upper hopper goes up, the limestone and coke feeder runs again to add limestone and coke into the limestone weighing hopper and coke weighing hopper again.

[0003] The existing coke weighing bucket often has the following problems during use: (1) The two bolts fixing the gate of the coke weighing bucket are frequently impacted and worn during use. When the bolts are used for more than 2 months, the bolts may suddenly break, causing the gate to fall out and unable to be closed tightly, resulting in the coke weighing bucket being unable to be normally charged. (2) When replacing the coke weighing bucket, three 14# channel steels need to be welded at the three vertical panels for fixing. During welding, it will take a long time for maintenance. (3) When the coke flows from the gate of the coke weighing bucket to the mixed material chute, some coke with smaller particle size is easy to leak out from the bottom plate of the coke weighing bucket, resulting in material waste. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a vertical kiln coke batching structure, which changes the gate connection form of the weighing bucket and changes the weighing bucket to be detachably connected to the structural wall or frame.

[0005] To achieve this technical purpose, the utility model adopts the following scheme: a vertical kiln coke batching structure, including a material chute, a belt conveyor and a coke weighing bucket of a coke storage unit; a quick-opening door structure is arranged at the outlet of the chute, a belt conveyor is arranged below the chute outlet, a coke recovery box is arranged around the belt conveyor, one end of the belt conveyor is located above the weighing bucket, the weighing bucket is detachably hung on the load-bearing structure, and a rotatably connected flip-type gate is provided at the outlet of the weighing bucket.

[0006] Compared with the prior art, the beneficial effects of the utility model are: the structure changes the door panel connection structure of the chute, which makes unloading faster and more convenient; a coke recovery box is arranged on the periphery of the belt conveyor to recover the coke attached to the belt, thereby reducing resource waste; the original bolt-connected weighing bucket gate is changed to a shaft sleeve connection form, which has a durable structure, and the weighing bucket is detachably mounted on the structural wall or frame for easy replacement.

[0007] Furthermore, the quick-opening door structure includes a shackle, a stopper and a rotatable door panel, the upper end of the door panel is connected to a rotating shaft, an ear panel with a hole is fixed on the chute body, and the rotating shaft is inserted on the ear panel; shackles are fixed on both sides of the chute body, and the stopper is fixed on the outer wall of the door panel and stuck between the door panel and the shackle. When wood or cement blocks are stuck at the bottom of the chute, causing the coke to be unable to be pulled out normally through the belt, it is only necessary to open the chute door panel, open the shackle, and lift the door panel through the stopper to remove the wood or cement blocks, so that the coke can be pulled out normally through the belt.

[0008] Furthermore, the upper end of the coke recovery box is an open structure, and the lower end surface is an inclined plate body. The side wall of the coke recovery box is provided with an outlet for the belt conveyor, and an upwardly inclined rubber scraper is fixed at the outlet, and a gap is left between the top of the rubber scraper and the belt of the belt conveyor. The rubber scraper scrapes off the coke adhering to the belt, and the coke falls into the weighing bucket. If the coke that is not scraped off falls during the rotation process, it will fall into the coke recovery box, avoiding the waste of raw materials and ensuring a clean production environment.

[0009] Furthermore, a movable lifting lug is fixed to the outer wall of the weighing bucket, a fixed lifting lug is fixed to the load-bearing structure, and the movable lifting lug is detachably inserted into the fixed lifting lug; when the weighing bucket needs to be replaced, the weighing bucket can be lifted up for quick replacement, thus avoiding welding operations.

[0010] Furthermore, a symmetrically arranged C-shaped shaft is fixed to the outer wall of the outlet of the weighing bucket, a shaft sleeve is installed on the C-shaped shaft, and the outer ring of the shaft sleeve is fixedly connected to the flip-type gate. The connection between the shaft and the shaft sleeve has a longer service life and is more flexible in rotation.

[0011] Furthermore, an extended bottom plate is fixed at the outlet of the weighing bucket, and the width of the bottom plate is greater than the outlet width of the weighing bucket, so that some coke with smaller particle size can also smoothly enter the mixed material chute.

[0019] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific implementation methods, but the present invention is not limited thereto.

[0020] like Figure 1 As shown, the utility model provides a vertical kiln coke batching structure, including a coke storage unit 1, a material chute 2, a belt conveyor 3 and a coke weighing bucket 5. The storage unit 1 is connected to the material chute 2 at the bottom, and the lower end of the material chute 2 extends into the coke recovery box 4. The belt conveyor 3 is arranged in the coke recovery box 4. The material chute 2 is located above one end of the belt conveyor 3, and the other end of the belt conveyor 3 extends out of the coke recovery box 4, and the coke weighing bucket 5 is located below this end. In order to extend the belt conveyor 3, an outlet is opened on the side wall of the coke recovery box 4, and the lower edge of the outlet is connected to a rubber scraper 41. The upper end of the rubber scraper 41 is close to the belt of the belt conveyor 3 but not in contact with it. The rubber scraper 41 is used to scrape off the coke attached to the belt and drop it into the coke weighing bucket 5; if the coke not scraped off by the rubber scraper 41 is vibrated and falls during the rotation process, it will fall into the coke recovery box 4, completing the recycling of materials, avoiding the waste of raw materials, and ensuring the cleanliness of the production environment. Figure 3 Preferably, the upper end of the coke recovery box 4 is an open structure, and the lower end surface is an inclined plate body, and a discharge port is provided at the lowest position of the plate body to regularly clean and discharge the coke in the coke recovery box 4.

[0021] like Figure 2As shown, the lower end of the material chute 2 is provided with a quick-opening door structure, which includes a shackle 21, a stopper 22 and a rotatable door panel 23. The upper end of the door panel 23 is connected to a rotating shaft 24. A hole ear plate 25 is fixed on the chute body, and the rotating shaft 24 is inserted on the ear plate 25. Preferably, the hole on the ear plate 25 is a threaded hole, and the rotating shaft 24 is provided with an external thread matching the threaded hole. The threaded connection plays a similar role to damping during the rotation of the door panel 23. Shackles 21 are fixed on both sides of the chute body, and the stopper 22 is fixed on the outer wall of the door panel 23 and stuck between the door panel 23 and the shackle 21. This is the closed state of the material chute 2. When wood or cement blocks are stuck at the bottom of the material chute 2, causing the coke to be unable to be pulled out normally through the belt, it is only necessary to open the chute door panel 23, open the shackle 21, and lift the door panel 23 through the stopper 22 to remove the wood or cement blocks, so that the coke can be pulled out normally through the belt.

[0022] like Figures 4 to 6 As shown, the outer wall of the coke weighing bucket 5 is fixed with a movable lifting lug 55. Preferably, the movable lifting lug 55 is fixed to the three outer walls. A fixed lifting lug 56 is fixed to the load-bearing structure (load-bearing wall or steel structure frame). Figure 6 As shown, the movable lifting ear 55 is a plate that is inserted and matched with the fixed lifting ear 56 structure. Figure 5 As shown, the movable lifting lug 55 is inserted into the fixed lifting lug 56, and the coke weighing bucket 5 is installed in the production setting position and can be used normally. When the coke weighing bucket 5 needs to be replaced, the coke weighing bucket 5 can be quickly replaced by lifting it to avoid welding workload.

[0023] A symmetrically arranged C-shaped shaft 52 is fixed to the outer wall of the outlet of the coke weighing bucket 5, and a shaft sleeve 53 is installed on the C-shaped shaft 52. The outer ring of the shaft sleeve 53 is fixedly connected to the flip-type gate 51, and a handle is provided on the flip-type gate 51. The flip-type gate 51 is flipped by holding the handle. The rotation form of the shaft and the shaft sleeve has a longer service life and a more flexible rotation action. In some preferred embodiments, an extended bottom plate 54 is fixed at the outlet of the coke weighing bucket 5, and the width of the bottom plate 54 is greater than the outlet width of the coke weighing bucket 5, so that some coke with smaller particle size can also smoothly enter the mixed material chute.

[0024] Finally, it should be noted that the above-listed examples are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and modifications fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
