Description

Technical Field

[0001] The present application relates to the technical field of coke oven tamping, and in particular to a coke oven tamping machine. Background Art

[0002] Coke oven tamping machine is mainly used to tamp the prepared coal into briquettes during the coking process, and push the briquettes from the side of the coke oven into the carbonization chamber for high-temperature dry distillation. This process is an important part of the coking process. Through the action of the tamping machine, the loose coal can be tightly compacted into briquettes with a certain shape and strength.

[0003] A related coke oven tamping machine, wherein the tamping machine includes a driving mechanism, a tamping hammer and a guide roller for guiding the movement of the tamping hammer, wherein the tamping hammer includes a hammer rod and a hammer head, the hammer head is arranged at one end of the hammer rod, and the driving mechanism drives the hammer rod to drive the tamping hammer to move along the guide direction of the guide roller, so that the hammer head acts on the coke to tamp the coke.

[0004] However, during the coke tamping process, coke will adhere to the inner wall of the tamping machine. After long-term use, a large amount of coke will adhere to the inner side of the tamping machine, which cannot be tamped, resulting in a waste of coke. Summary of the invention

[0005] In order to reduce the problem of material waste, the present application provides a coke oven tamping machine.

[0006] The present application provides a coke oven tamping machine, which adopts the following technical solution:

[0007] A coke oven tamping machine comprises a tamping barrel, wherein the tamping barrel is provided with a discharge cavity, and further comprises:

[0008] An electric telescopic rod, the fixed end of which is fixedly arranged at the upper end of the tamping barrel;

[0009] A tamping hammer, one end of which is fixed to the telescopic end of the electric telescopic rod, and the telescopic end of the electric telescopic rod passes through the tamping barrel and is slidably disposed in the discharge cavity;

[0010] An airbag, the upper end of which is fixedly arranged at the upper end of the discharge cavity, and the airbag is coaxially arranged with the electric telescopic rod;

[0011] A scraper, the scraper is rotatably disposed on the inner wall of the discharge cavity, and the scraper is used to clean the inner wall of the discharge cavity;

[0012] A connecting piece is arranged on the airbag and is used for connecting the scraping piece and the airbag.

[0013] By adopting the above technical solution, when the electric telescopic rod is working, it drives the tamping hammer to move up and down to tamp the material in the discharge chamber. When the tamping hammer moves upward, it squeezes the airbag, allowing the gas in the airbag to enter the connecting piece, and then drives the scraper to scrape the material on the side wall of the discharge chamber through the connecting piece. When the scraper moves to the end point, the material on the inner wall of the discharge chamber is scraped in the opposite direction to clean the inner wall of the discharge chamber, thereby reducing material waste.

[0014] Optionally, a slide groove is provided on the peripheral side of the tamping barrel, and the scraper comprises:

[0015] A telescopic tube, wherein the telescopic tube is disposed in the chute, and one end of the telescopic tube is fixedly connected to the bottom wall of the chute;

[0016] A scraper is fixedly connected to one end of the telescopic tube, and the scraper is fixedly connected to one end of the telescopic tube away from the bottom wall of the chute.

[0017] By adopting the above technical solution, when the tamping barrel is working, the telescopic tube slides in the slide groove, driving the scraper to move along the inner wall, thereby scraping off the adhered material, which is simple and easy to operate.

[0018] Optionally, the connecting member is a connecting tube, one end of which is connected to the airbag, and the other end of which is connected to the telescopic tube.

[0019] By adopting the above technical solution, when the tamping hammer moves upward to squeeze the airbag, the gas in the airbag enters the connecting pipe, and then the gas enters the telescopic tube through the connecting pipe, driving the telescopic tube to extend, thereby driving the scraper to scrape the surrounding side of the discharge cavity, which is convenient and quick.

[0020] Optionally, an electromagnetic exhaust valve is provided on one side of the tamping barrel, and the electromagnetic exhaust valve is connected to the telescopic tube. A switch is provided at one end of the slide groove away from the electric telescopic rod, and the switch is electrically connected to the electromagnetic exhaust valve.

[0021] By adopting the above technical solution, since the electromagnetic exhaust valve is electrically connected to the switch, and the switch is set in the slide slot, the opening and closing of the electromagnetic exhaust valve can be directly controlled when the telescopic tube is moving. When the telescopic tube reaches the end position, that is, the telescopic tube needs to be exhausted, and then the scraper touches the switch, thereby activating the electromagnetic exhaust valve to start working. When the telescopic tube contracts, the scraper is separated from the switch, so that the electromagnetic exhaust valve is closed, so that the electromagnetic exhaust valve can be opened and closed without manual intervention, thereby improving the degree of automation.

[0022] Optionally, a one-way valve is provided at the upper end of the tamping barrel, and the one-way valve is connected to the airbag.

[0023] By adopting the above technical solution and setting the one-way valve, the gas can only enter the airbag and cannot be discharged from the airbag, thereby ensuring the directionality and efficiency of the airbag inflation.

[0024] Optionally, an elastic rope is provided in the telescopic tube, one end of the elastic rope is fixedly connected to the bottom wall of the slide groove, and the other end of the elastic rope is connected to two ends of the scraper.

[0025] By adopting the above technical solution, when the scraper finishes moving in the slide groove, the elastic rope will use its own elastic recovery ability to help the scraper return to its original position, ready for the next use, thereby improving work efficiency and operational convenience.

[0026] Optionally, both ends of the scraper are provided with guiding slopes.

[0027] By adopting the above technical solution and setting the guiding inclined surface, the material can be prevented from accumulating on the scraper when the scraper is scraping the material.

[0028] Optionally, a slide rail is provided at the bottom end of the tamping barrel.

[0029] By adopting the above technical solution, the setting of the slide rail facilitates the movement of the tamping bucket and increases the applicability of the tamping bucket.

[0030] In summary, the embodiment of the present invention provides a coke oven tamping machine, which includes at least one of the following beneficial technical effects:

[0031] 1. The electric telescopic rod drives the tamping hammer to perform telescopic movement in the discharge chamber, which can fully compact the coke raw materials and improve the tamping efficiency. The setting of the airbag can work together with the scraper and the connecting piece to clean the inner wall of the discharge chamber, thereby reducing material waste.

[0032] 2. When the tamping barrel is working, the telescopic tube slides in the chute, driving the scraper to move along the inner wall, thereby scraping off the adhering materials. It is simple and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following is combined with Figure 1-4 This application is described in further detail.

[0040] Combination Figure 1 and Figure 2 The embodiment of the present application discloses a coke oven tamping machine, comprising: a tamping barrel 11, the tamping barrel 11 is provided with a discharge chamber 12, and also comprises an electric telescopic rod 13, a tamping hammer 14, an airbag 15, a scraper 2, and a connecting piece 16. The fixed end of the electric telescopic rod 13 is fixedly arranged at the upper end of the tamping barrel 11, one end of the tamping hammer 14 is fixedly arranged at the telescopic end of the electric telescopic rod 13, the telescopic end of the electric telescopic rod 13 passes through the tamping barrel 11 and is slidably arranged in the discharge chamber 12, the upper end of the airbag 15 is fixedly arranged at the upper end of the discharge chamber 12, the airbag 15 is coaxially arranged with the electric telescopic rod 13, the scraper 2 is rotatably arranged on the inner side wall of the discharge chamber 12, the scraper 2 is used to clean the inner side wall of the discharge chamber 12, and the connecting piece 16 is arranged on the airbag 15 for connecting the scraper 2 and the airbag 15. The connecting member 16 is a connecting tube, one end of which is connected to the airbag 15 , and the other end of which is connected to the telescopic tube 21 .

[0041] In the embodiment of the present application, the tamping barrel 11 and the discharge chamber 12 are both cylindrically arranged, and the discharge chamber 12 is used to hold coke, and the tamping hammer 14 is disc-shaped, wherein the tamping hammer 14 can be made of steel or alloy steel, and the weight is set according to the specific usage, which is not specifically limited in the embodiment of the present application. The tamping hammer 14 and the telescopic end of the electric telescopic rod 13 can be integrally formed, or fixedly connected by welding or bolting, so as to ensure the connection stability between the tamping hammer 14 and the electric telescopic rod 13. The airbag 15 is annularly arranged, wherein the upper end of the airbag 15 is fixedly connected to the discharge chamber 12. The presence of the airbag 15 can not only drive the scraper 22 to move, but also provide a buffer for the tamping hammer 14, so as to prevent the tamping hammer 14 from damaging the upper end of the tamping barrel 11 during the upward movement. There is gas inside the airbag 15. It should be noted that the material of the airbag 15 is polyurethane, which is a material with high elasticity and impact resistance. It can deform quickly during a collision and absorb collision energy. In addition, the polyurethane material is also highly wear-resistant and tear-resistant and can withstand huge impact forces. The connecting pipe is cylindrical. It should be noted that a one-way valve 33 is provided in the connecting pipe to maintain the position stability of the scraper 2 and prevent the gas in the scraper 2 from flowing back into the airbag 15, causing the scraper 2 to move backward.

[0042] During specific use, when the electric telescopic rod 13 is working, it drives the tamping hammer 14 to move up and down to tamp the material in the discharge chamber 12. When the tamping hammer 14 moves upward, it will squeeze the airbag 15, so that the gas in the airbag 15 enters the connecting pipe, and then drives the scraper 2 through the connecting pipe to scrape the material on the side wall of the discharge chamber 12. When the scraper 2 moves to the end point, the scraper 22 returns to its original position. At the same time, when resetting, the material on the inner wall of the discharge chamber 12 is scraped in the reverse direction, thereby reducing material waste.

[0043] Combination Figure 2 , Figure 3 and Figure 4 In a specific embodiment, a chute 17 is provided on the peripheral side of the tamping barrel 11, and the scraper 2 includes a telescopic tube 21 and a scraper 22. The telescopic tube 21 is provided in the chute 17, one end of the telescopic tube 21 is fixedly connected to the bottom wall of the chute 17, the scraper 22 is fixedly connected to one end of the telescopic tube 21, and the scraper 22 is fixedly connected to one end of the telescopic tube 21 away from the bottom wall of the chute 17. Both ends of the scraper 22 are provided with guide slopes 35.

[0044] In the embodiment of the present application, the chute 17 is arranged in a spiral ring shape, wherein the chute 17 is a T-shaped groove, and the chute 17 is used to accommodate the telescopic tube 21 and the scraper 2, and provide guidance for the telescopic movement of the telescopic tube 21. The specifications of the telescopic tube 21 can be just placed in the chute 17, and the telescopic tube 21 can be a bellows, wherein the bellows is made of metal material, which increases the service life of the bellows. The scraper 22 is arranged in a triangular plate shape, and the long side of the scraper 22 is in contact with the inner wall of the discharge chamber 12, and the inclined side is used to scrape the material attached to the inner wall of the discharge chamber 12. Among them, the material of the scraper 22 can be rubber material, or it can be a silicone scraper 22, which has good wear resistance and abrasion resistance. The scraper 22 and the telescopic tube 21 can be integrally formed, or they can be fixedly connected by bonding, which is not specifically limited in the embodiment of the present application. Specifically, an elastic rope 34 is provided in the telescopic tube 21, one end of the elastic rope 34 is fixedly connected to the bottom wall of the slide groove 17, and the other end of the elastic rope 34 is connected to both ends of the scraper 22. The provision of the elastic rope 34 can help to retract the telescopic tube 21, and the length of the elastic rope 34 is set according to the specific use situation, and the embodiment of the present application does not make a specific limitation.

[0045] In specific use, when the tamping hammer 14 moves upward to squeeze the airbag 15, the gas in the airbag 15 enters the connecting pipe, and then the gas enters the telescopic tube 21 through the connecting pipe, driving the telescopic tube 21 to extend, and then the telescopic tube 21 drives the scraper 22 to move and scrape the material around the discharge chamber 12. When the tamping hammer 14 descends, the position of the scraper 22 does not change. When the tamping hammer 14 rises next time, the scraper 22 continues to move forward driven by the gas. Due to the existence of the guide slope 35, the scraped material will not adhere to the scraper 22. The setting of the elastic rope 34 makes it possible for the elastic recovery ability of the elastic rope 34 to drive the telescopic tube 21 to contract when the scraper 22 moves to the terminal position without the effect of gas driving, and the operation is simple and convenient.

[0046] Replay combination Figure 3 In a specific embodiment, a solenoid exhaust valve 31 is provided on one side of the tamping barrel 11, and the solenoid exhaust valve 31 is connected to the telescopic tube 21. A switch 32 is provided at one end of the slide 17 away from the electric telescopic rod 13, and the switch 32 is electrically connected to the solenoid exhaust valve 31. A one-way valve 33 is provided at the upper end of the tamping barrel 11, and the one-way valve 33 is connected to the airbag 15. Specifically, a slide rail 36 is provided at the bottom end of the tamping barrel 11.

[0047] In the embodiment of the present application, the electromagnetic exhaust valve 31 is connected to the telescopic tube 21. The electromagnetic exhaust valve 31 is responsible for controlling the discharge of gas. By controlling its opening and closing, the air pressure in the telescopic tube 21 can be adjusted. The function of the one-way valve 33 is to allow gas to enter the airbag 15 from only one direction to prevent gas backflow. In specific use, when external gas enters the airbag 15, the valve flap of the one-way valve 33 opens under the action of gas pressure to allow gas to pass through. When the gas attempts to flow back from the airbag 15 to the outside, the valve flap closes under the action of the spring to prevent gas backflow. When the telescopic tube 21 extends to one end of the chute 17, it means that the scraper 22 cannot move. Therefore, in order to make the scraper 22 continue to move, the scraper 22 needs to be restored to the initial position and then moved again. Therefore, when the scraper 22 reaches the end of the chute 17, the scraper 22 touches the switch 32, so that the circuit of the electromagnetic exhaust valve 31 is connected, and the electromagnet generates magnetic force to attract the valve core, so that the valve core opens, and the gas is discharged from the exhaust port. When the scraper 22 returns to the initial state, that is, the scraper 22 leaves the switch 32, the electromagnet loses its magnetic force, the valve core is closed under the action of the spring, and the exhaust stops. The slide rail 36 is provided so that the tamping barrel 11 can be moved to facilitate tamping of materials at various positions.

[0048] The implementation principle of the embodiment of the present application is: when the electric telescopic rod 13 is working, it drives the tamping hammer 14 to move up and down to tamp the material in the discharge chamber 12. When the tamping hammer 14 moves upward, it squeezes the airbag 15, so that the gas in the airbag 15 enters the connecting pipe, and then drives the scraper 2 through the connecting pipe to scrape the material on the side wall of the discharge chamber 12, thereby reducing material waste.

[0049] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
