Description

Technical Field

[0001] This utility model relates to the technical field of scraper conveying equipment, specifically to a coke oven pusher scraper machine. Background Technology

[0002] In coke oven pushing operations, scraper conveyors, as the core equipment for coke conveying and collection, have long faced problems such as difficulty in adjusting scraper pressure, easy loosening and breakage of chains, and low efficiency in coke grading. Traditional scraper conveyors rely on manual adjustment of the contact pressure between the scraper and the conveying surface, which has low adjustment accuracy and slow response, leading to scraper jamming or excessive wear; the chains are prone to loosening and derailment due to long-term impact from coke and thermal expansion and contraction, requiring frequent shutdowns for tensioning and maintenance, which seriously affects the continuity of production. Utility Model Content

[0003] The purpose of this utility model is to provide a coke oven scraper pusher to solve the problems of easy scraper damage and chain loosening.

[0004] To achieve the above objectives, the basic solution provided by this utility model is as follows: a coke oven scraper pusher, comprising a housing, a conveyor belt, a chain, and a scraper. The conveyor belt is located inside the housing, and the chain rotates around the shaft of the conveyor belt. A first sliding groove is fixedly connected to the housing, and a first slider is slidably connected to the first sliding groove. A lifting rod is fixedly connected to the first slider. A second sliding groove is formed on the first sliding groove, and a second slider is slidably connected to the second sliding groove. The lifting rod is threaded through the second sliding groove. Both ends of the scraper are fixedly connected to the chain, and an adjusting rod is fixedly connected to the end of the scraper. The adjusting rod is threaded through the outer wall of the housing. A spring is sleeved on the outside of the lifting rod, and the spring is located between the first slider and the scraper.

[0005] The principle and beneficial effects of this invention are as follows: By rotating the threaded adjusting rod outside the housing, the angle of the scraper is adjusted. The chain rotates with the conveyor belt shaft, pulling the scraper to move, and the first slider moves with the chain. When the scraper encounters a large piece of coke or a hard object, the spring compresses to absorb the impact force, preventing the scraper from deforming. After the impact disappears, the spring pushes the scraper back to its original position, maintaining stable contact between the scraper and the conveying surface. Precise control of the scraper pressure is achieved through mechanical adjustment, adapting to different material thicknesses and hardnesses, and reducing jamming and wear.

[0006] Option 2, a preferred embodiment of the basic option, has an adjusting groove fixedly connected to the outer wall of the housing. An adjusting bolt is threaded through the adjusting groove, and a bearing seat is rotatably connected to the end of the adjusting bolt. A tensioning wheel is rotatably connected to the bearing seat, and the bearing seat is slidably connected to the adjusting groove. The tensioning wheel has anti-slip textures on its surface. Rotating the adjusting bolt causes the screw's axial movement to move the tensioning wheel along the guide adjusting groove, thus tightening the chain and compensating for chain slack caused by wear or thermal expansion and contraction. The anti-slip textures on the tensioning wheel engage with the chain, increasing friction and preventing chain slippage or skipping. This dynamic compensation of chain tension eliminates the need for frequent manual adjustments, reducing the risk of chain breakage.

[0007] Option 3, a preferred option of the basic scheme, involves an upward tilt of the rear end of the container at 15°-25°. A tail coke hopper is located at the bottom of the container, and a detachable screen with a mesh size of 5-10mm is installed at the outlet of the tail coke hopper. With the rear end of the container tilted upwards at 15°-25°, the coke slides down the tilted section under gravity. The detachable screen intercepts lumps of coke larger than 5-10mm, while finer coke passes through the screen and falls into the lower collection device, achieving automatic grading.

[0008] Option 4, a preferred embodiment of the basic option, involves welding U-shaped guide rails to both sides of the chain's running path. These guide rails are embedded with high-polymer wear-resistant liners, each 3-5mm thick. A limiting stop is located at the top of the guide rail, with a height equal to half the chain diameter. The side walls of the U-shaped guide rails restrict lateral chain displacement, while the top limiting stop prevents lateral chain jumps. The polymer liner reduces frictional wear between the chain and the guide rails, significantly lowering the probability of chain derailment and extending the lifespan of both the chain and the guide rails.

[0009] Option 5, a preferred option of the basic scheme, involves connecting the scraper and the lifting rod via a dovetail groove structure, with the scraper being a triangular prism. The scraper has three working surfaces, eliminating the need for frequent replacements. Attached Figure Description

[0016] Example

[0017] like Figures 1 to 4 The following describes a coke oven scraper conveyor, comprising a housing 1, a conveyor belt 2, a chain 3, and a scraper 4. The scraper 4 is a triangular prism-shaped scraper. The conveyor belt 2 is located inside the housing 1. The chain 3 surrounds the pivot of the conveyor belt 2. An adjusting groove 12 is fixedly connected to the outer wall of the housing 1. An adjusting bolt 13 is threaded through the adjusting groove 12. A bearing seat 14 is rotatably connected to the end of the adjusting bolt 13. A tension wheel 15 is rotatably connected to the bearing seat 14. The bearing seat 14 is slidably connected to the adjusting groove 12. The surface of the tension wheel 15 is provided with anti-slip texture. The tail end of the housing 1 is inclined upward at 15°-25°. A tail coke hopper 16 is provided at the bottom of the housing 1. A detachable screen 17 is installed at the outlet of the tail coke hopper 16. The screen 17 has an aperture of 5-10mm. A first sliding groove is fixedly connected to the housing 1. 5. A first slider 6 is slidably connected to the first slide groove 5. A lifting rod 7 is fixedly connected to the first slider 6. A second slide groove 8 is opened on the first slide groove 5. A second slider 9 is slidably connected to the second slide groove 8. The lifting rod 7 is threaded through the second slider 9. The two ends of the scraper 4 are fixedly connected to the chain 3. An adjusting rod 11 is fixedly connected to the end of the scraper 4. The adjusting rod 11 is threaded through the outer wall of the housing 1. A spring 10 is sleeved on the outside of the lifting rod 7. The spring 10 is located between the first slider 6 and the scraper 4. U-shaped guide slides 18 are welded on both sides of the running path of the chain 3. The slides are embedded with high-polymer wear-resistant liners with a thickness of 3-5mm. A limiting stop 19 is provided at the top of the guide slide 18. The height of the limiting stop 19 is 1 / 2 of the diameter of the chain 3.

[0018] The implementation method of this embodiment is as follows: By rotating the threaded adjusting rod 11 on the outside of the rotating housing 1, the angle of the scraper 4 is adjusted. The chain 3 rotates with the drive shaft of the conveyor belt 2, and the chain 3 pulls the scraper 4 to move. The first slider 6 moves with the chain 3. When the scraper 4 encounters a large piece of coke or a hard object, the spring 10 is compressed to absorb the impact force and prevent the scraper 4 from deforming. After the impact disappears, the spring pushes the scraper 4 to return to its original position. Rotating the adjusting bolt 13 causes the axial movement of the adjusting bolt 13 to push the tension wheel 15 to move along the guide adjusting groove 12. The tension wheel 15 presses the chain 3 to compensate for the slack caused by wear or thermal expansion and contraction of the chain 3. The two side walls of the U-shaped guide slide 18 restrict the lateral displacement of the chain 3, and the top limiting stop 19 prevents the chain 3 from jumping laterally.
