Description

Technical Field

[0001] This utility model relates to the field of coke oven coking technology, specifically to a graphite cleaning device for a carbonization chamber. Background Technology

[0002] During the daily production process of a coke oven, a layer of graphite will form on the furnace wall of the coking chamber. When the graphite on the furnace wall is too thick, it will cause excessive coke pushing current, and may even cause coke pushing accidents, thereby affecting the stability of coke oven production and service life. In coking enterprises, the graphite on the furnace wall is usually removed by blowing it with air pipes.

[0003] A search revealed that patent CN201376951Y discloses a graphite purging tool for the furnace wall of a coke oven carbonization chamber. This tool is made by adding a mixed air jet pipe, hot air, an intake port, a compressed air guide port, and a compressed air pressure regulating device. The compressed air forms a negative pressure zone near the hot air inlet through the compressed air guide port, thereby allowing hot air from the carbonization chamber to be introduced into the chamber simultaneously through the hot air inlet. This significantly increases the temperature of the air purged onto the graphite surface, thereby improving the reaction rate between the purging air and the graphite.

[0004] The aforementioned patent describes a method to improve the reaction efficiency of graphite by increasing the temperature of the compressed air sprayed onto the graphite surface, thereby improving the cleaning efficiency. However, this device only uses compressed air for cleaning, and its cleaning effect is poor for some stubborn deposits. Therefore, we provide a graphite cleaning device for a carbonization chamber to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a graphite cleaning device for a carbonization chamber to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A graphite cleaning device for a carbonization chamber includes an air compressor, the output end of which is fixedly connected to a high-pressure air pipe, a coke pushing unit is provided on the side of the high-pressure air pipe, a graphite cleaning mechanism is provided on the side of the coke pushing unit, and a base plate is movably connected to the bottom surface of the coke pushing unit.

[0008] The graphite cleaning mechanism includes a waste hopper, which is fixedly connected to the top surface of the coke pushing unit. A gas distribution pipe is fixedly connected to the top surface of the waste hopper, and a high-pressure nozzle is fixedly connected to the top surface of the gas distribution pipe.

[0009] A telescopic rod is fixedly connected to the top surface of the waste hopper, and a bracket is fixedly connected to the output end of the telescopic rod. A crushing roller is rotatably connected inside the bracket, and a limit rod is fixedly connected to the bottom surface of the bracket. The limit rod is slidably connected inside the top surface of the waste hopper.

[0010] A further improvement of the present invention is that: a cleaning roller is rotatably connected inside the top surface of the waste hopper, a follower wheel is fixedly connected to the side of the cleaning roller, a bevel tooth is fixedly connected to the side of the follower wheel, and a motor is fixedly connected to one end of the back of the waste hopper.

[0011] A further improvement of the present invention is that: the output end of the motor is fixedly connected to a drive wheel, the outer surface of the drive wheel is movably connected to a transmission chain, and the other end of the transmission chain is movably connected to the inside of the follower wheel.

[0012] A further improvement of this utility model is that: a second conical tooth is movably connected to the side of the first conical tooth, a cleaning roller is fixedly connected to the bottom surface of the second conical tooth, a fixed frame is fixedly connected to the back of the waste hopper, and the cleaning roller is rotatably connected inside the fixed frame.

[0013] A further improvement of the present invention is that the coking unit includes a protective sleeve, the protective sleeve is fixedly connected to the outer surface of the high-pressure air pipe, a slider is fixedly connected to the bottom surface of the protective sleeve, and the base plate is slidably connected to the outer surface of the slider.

[0014] A further improvement of this utility model is that: a side air pipe is fixedly connected to the side of the sheath, a side nozzle is fixedly connected to the output end of the side air pipe, a main air pipe is fixedly connected to the top surface of the slider, a coke pusher is fixedly connected to the side of the slider, and the waste hopper is fixedly connected to the top surface of the coke pusher.

[0015] A further improvement of this utility model is that: a rack is fixedly connected to the bottom surface of the slider, a gear is movably connected to the bottom surface of the rack, a second motor is fixedly connected to the side of the gear, and the second motor is fixedly connected inside the base plate.

[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0017] 1. This utility model provides a graphite cleaning device for a carbonization chamber. The coke inside the coke oven is pushed out by the coke pushing unit. When the slider pushes the coke, the graphite cleaning mechanism moves together with the coke pushing unit. At this time, the gas distribution pipe will pre-purge the graphite attached to it through a high-pressure nozzle with a larger port diameter to reduce its adhesion.

[0018] The high-pressure nozzle facing the other direction will spray high-pressure air to further oxidize the graphite. At the same time, the high-pressure gas reduces the adhesion of the graphite, making it easier to peel off the graphite later.

[0019] The telescopic rod is pushed by the bracket and pressed against the inner top surface of the coking furnace. As the coking unit continues to move forward, the crushing roller moves forward with the coking unit, causing the crushing roller to roll. The sharp points on the surface of the crushing roller break up the attached graphite, making it easier to clean later.

[0020] Once the motor drives the drive wheel to rotate, the transmission chain will drive the follower wheel to rotate, which in turn drives the cleaning roller to rotate. The cleaning roller will sweep the broken graphite on the top surface of the coke oven, causing it to fall off the top surface of the coke oven and into the interior of the waste hopper.

[0021] While the follower wheel rotates, the first bevel tooth drives the cleaning roller to rotate through the second bevel tooth, cleaning the inner wall of the coke oven and removing the small amount of graphite adhering to the inner wall of the coke oven.

[0022] 2. This utility model provides a graphite cleaning device for a carbonization chamber. The motor drives the gear to rotate, and the gear meshing with the motor drives the slider to move, which plays the role of pushing coke and pushing out the coke inside the coke pusher.

[0023] The air compressor delivers clean, high-pressure air through high-pressure pipes to the interior of the main and side pipes. Sheaths protect the high-pressure pipes from damage during normal operation in high-temperature environments. Side nozzles purge the coke oven sidewalls as the coke pusher moves forward, facilitating cleaning by the graphite cleaning mechanism. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to embodiments:

[0031] Example 1: As Figure 1-5 As shown, this utility model provides a graphite cleaning device for a carbonization chamber, including an air compressor 1, a high-pressure air pipe 2 fixedly connected to the output end of the air compressor 1, a coke pushing unit 4 provided on the side of the high-pressure air pipe 2, a graphite cleaning mechanism 5 provided on the side of the coke pushing unit 4, and a base plate 3 movably connected to the bottom surface of the coke pushing unit 4.

[0032] The graphite cleaning mechanism 5 includes a waste hopper 51, which is fixedly connected to the top surface of the coke pushing unit 4. A gas distribution pipe 52 is fixedly connected to the top surface of the waste hopper 51, and a high-pressure nozzle 53 is fixedly connected to the top surface of the gas distribution pipe 52.

[0033] A cleaning roller 58 is rotatably connected inside the top surface of the waste hopper 51. A follower wheel 59 is fixedly connected to the side of the cleaning roller 58. A bevel tooth 510 is fixedly connected to the side of the follower wheel 59. A motor 511 is fixedly connected to one end of the back of the waste hopper 51.

[0034] The output end of motor 511 is fixedly connected to drive wheel 512, and the outer surface of drive wheel 512 is movably connected to transmission chain 513. The other end of transmission chain 513 is movably connected to the inside of follower wheel 59.

[0035] A second conical tooth 514 is movably connected to the side of the first conical tooth 510. A cleaning roller 515 is fixedly connected to the bottom surface of the second conical tooth 514. A fixed frame 516 is fixedly connected to the back of the waste hopper 51. The cleaning roller 515 is rotatably connected inside the fixed frame 516.

[0036] A telescopic rod 54 is fixedly connected to the top surface of the waste hopper 51. A bracket 55 is fixedly connected to the output end of the telescopic rod 54. A crushing roller 56 is rotatably connected inside the bracket 55. A limit rod 57 is fixedly connected to the bottom surface of the bracket 55. The limit rod 57 is slidably connected inside the top surface of the waste hopper 51.

[0037] In this embodiment, there are two sets of high-pressure nozzles 53, which are opposite in direction and have different diameters. The crushing roller 56 is pressed against the top surface of the coking furnace under the thrust of the telescopic rod 54. There are two cleaning rollers 515, which are fixed to the left and right ends of the waste hopper 51 by the fixing frame 516.

[0038] The coke pushing unit 4 drives the coke inside the coke oven to exit. When the slider 41 pushes the coke, the graphite cleaning mechanism 5 will move together with the movement of the coke pushing unit 4. At this time, the gas distribution pipe 52 will pre-purge the graphite attached to it through a high-pressure nozzle 53 with a larger port diameter to reduce its adhesion.

[0039] The high-pressure nozzle 53 facing the other direction will spray high-pressure air to further react with the graphite to produce an oxidation reaction. At the same time, the high-pressure gas reduces the adhesion of the graphite, making it easier to peel off the graphite in the future.

[0040] The telescopic rod 54 is pushed by the bracket 55 and pressed against the inner top surface of the coking furnace. As the coking unit 4 continues to move forward, the crushing roller 56 moves forward with the coking unit 4, causing the crushing roller 56 to roll. The attached graphite is crushed by the spikes set on the surface of the crushing roller 56, which facilitates subsequent cleaning.

[0041] Motor 511 drives drive wheel 512 to rotate, transmission chain 513 drives follower wheel 59 to rotate, which in turn drives cleaning roller 58 to rotate. Cleaning roller 58 will clean the broken graphite on the top surface of coke oven, causing it to fall from the top surface of coke oven and into the interior of waste hopper 51.

[0042] While the follower wheel 59 rotates, the first bevel tooth 510 drives the cleaning roller 515 to rotate via the second bevel tooth 514, cleaning the inner wall of the coke oven and removing the small amount of graphite adhering to the inner wall of the coke oven.

[0043] Example 2: As Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the coking unit 4 includes a sheath 42, the sheath 42 is fixedly connected to the outer surface of the high-pressure air pipe 2, the bottom surface of the sheath 42 is fixedly connected to a slider 41, and the base plate 3 is slidably connected to the outer surface of the slider 41.

[0044] A side air pipe 43 is fixedly connected to the side of the sheath 42, and a side nozzle 44 is fixedly connected to the output end of the side air pipe 43. A main air pipe 45 is fixedly connected to the top surface of the slider 41, and a coke pusher 46 is fixedly connected to the side of the slider 41. A waste hopper 51 is fixedly connected to the top surface of the coke pusher 46.

[0045] A rack 47 is fixedly connected to the bottom surface of the slider 41, a gear 48 is movably connected to the bottom surface of the rack 47, a motor 49 is fixedly connected to the side of the gear 48, and the motor 49 is fixedly connected inside the base plate 3.

[0046] In this embodiment, the high-pressure air pipe 2 is protected by the sheath 42, the slider 41 is restricted to the direction of movement inside the base plate 3, the coke pusher 46 can carry the coke, there are two sets of side air pipes 43 and side nozzles 44, which are fixed at the left and right ends of the slider 41, and the main air pipe 45 is fixed at the input end of the sheath 42.

[0047] Motor 49 drives gear 48 to rotate, which in turn drives slider 41 to move through rack 47 meshing with it, thus pushing the coke out of the coke inside the coke pusher 46.

[0048] Air compressor 1 transmits clean, high-pressure air through high-pressure air pipe 2 to the interior of main air pipe 45 and side air pipe 43. Sheath 42 protects high-pressure air pipe 2 for normal operation in high-temperature environment. Side nozzle 44 blows on the side wall of coke oven during the forward movement of coke pusher 46, facilitating cleaning by graphite cleaning mechanism 5.

[0049] The working principle of the graphite cleaning device for the carbonization chamber will be explained in detail below.

[0050] like Figure 1-5 As shown, the motor 49 drives the gear 48 to rotate, and the rack 47 meshing with it drives the slider 41 to move, which plays the role of pushing coke and pushing out the coke inside the coke pusher 46.

[0051] Air compressor 1 transmits clean high-pressure air through high-pressure air pipe 2 to the inside of main air pipe 45 and side air pipe 43. Sheath 42 protects high-pressure air pipe 2 for normal operation in high-temperature environment. Side nozzle 44 blows on the side wall of coke oven during the forward movement of coke pusher 46, which facilitates cleaning by graphite cleaning mechanism 5.

[0052] The coke pushing unit 4 drives the coke inside the coke oven to exit. When the slider 41 pushes the coke, the graphite cleaning mechanism 5 will move together with the movement of the coke pushing unit 4. At this time, the gas distribution pipe 52 will pre-purge the graphite attached to it through a high-pressure nozzle 53 with a larger port diameter to reduce its adhesion.

[0053] The high-pressure nozzle 53 facing the other direction will spray high-pressure air to further react with the graphite to produce an oxidation reaction. At the same time, the high-pressure gas reduces the adhesion of the graphite, making it easier to peel off the graphite in the future.

[0054] The telescopic rod 54 is pushed by the bracket 55 and pressed against the inner top surface of the coking furnace. As the coking unit 4 continues to move forward, the crushing roller 56 moves forward with the coking unit 4, causing the crushing roller 56 to roll. The attached graphite is crushed by the spikes set on the surface of the crushing roller 56, which facilitates subsequent cleaning.

[0055] Motor 511 drives drive wheel 512 to rotate, transmission chain 513 drives follower wheel 59 to rotate, which in turn drives cleaning roller 58 to rotate. Cleaning roller 58 will clean the broken graphite on the top surface of coke oven, causing it to fall from the top surface of coke oven and into the interior of waste hopper 51.

[0056] While the follower wheel 59 rotates, the first bevel tooth 510 drives the cleaning roller 515 to rotate through the second bevel tooth 514, cleaning the inner wall of the coke oven and removing the small amount of graphite adhering to the inner wall of the coke oven.

[0057] After the coke pushing operation is completed and the device returns to its original position, the graphite can be removed from the inside of the waste hopper 51 for reuse.

[0058] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all modifications or improvements made without departing from the spirit and concept of the present invention are within the protection scope of the present invention.
