Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of coking production equipment, in particular to a residual coke cleaning device at the tail of a coke guide grid of a coke intercepting vehicle. Background Art
[0002] The coke interceptor is the main equipment in the coke smelting and coking process of the coking enterprise. The coke guiding device is one of the key components of the coke interceptor, among which the coke guiding grid is an important part of the coke guiding device. The coke guiding grid is used to intercept the red coke pushed out from the carbonization chamber and guide it into the coke tank of the coke quenching car.
[0003] After the coke pusher completes the coke pushing instruction, the red coke falls into the coke tank of the coke quenching car. Due to the design length and size of the coke pusher rod and the coke guide grid, there is usually about 20 to 30 kilograms of red coke left in the coke guide grid chute at the tail of the coke guide grid. This part of the red coke is scattered at this position and continues to burn. On the one hand, the red coke comes into contact with the air, causing it to burn directly in the air, and the carbon dioxide and harmful gases produced by the combustion are directly discharged into the air; on the other hand, the main body of the coke guide grid is made of carbon steel, and the bottom side plate is cast iron. The red coke burns in the air and releases heat. The coke guide grid absorbs heat locally for a long time, the wall thickness is thinned, the strength is reduced, and deformation occurs, which brings safety hazards and seriously shortens the service life.

[0004] In order to overcome the shortcomings and defects of the prior art that part of the red coke is scattered, the utility model provides a residual coke cleaning device at the tail of the focus guide grid of the coke intercepting vehicle, which can timely clean the remaining red coke at the tail of the focus guide grid to avoid this part of the red coke from burning in the air, while extending the maintenance and replacement cycle of the focus guide grid.
[0005] The technical solution adopted by the utility model to solve its technical problems is: a residual coke cleaning device at the tail of the coke guide grid of a coke intercepting vehicle, comprising a hydraulic station, one end of the hydraulic station is connected to a control switch arranged in the driving cab of the coke intercepting vehicle through a control valve, the other end of the hydraulic oil pump is connected to an oil cylinder installed on the external working surface of the coke guide grid through a hydraulic oil pipeline, the output end of the oil cylinder is hinged with a support arm, one end of the support arm is hinged to the external working surface of the coke guide grid, and the other end of the support arm extends to the coke guide grid and is provided with a heat-resistant lining.
[0006] As a further improvement of the utility model, the support arm and the heat-resistant lining plate are fixed with bolts, which is convenient for maintenance and replacement.
[0007] As a further improvement of the utility model, the oil cylinder and the hydraulic oil pipeline are both coated with a high temperature resistant coating.
[0008] As a further improvement of the present invention, the support arm is made of cast iron and has a strong ability to withstand high temperatures.
[0009] As a further improvement of the utility model, the oil cylinder and the support arm are both installed outside the focus guide grid.
[0010] As a further improvement of the utility model, the output end of the oil cylinder is hinged to the middle part of the support arm.
[0011] Compared with the prior art, the utility model has the following beneficial effects: after the coke pushing car completes the coke pushing action, the driver of the coke blocking car can control this device to clean up the remaining red coke at the tail of the coke guide grid and drop it into the coke tank of the coke quenching car, so as to avoid the red coke burning in the air and the generated carbon dioxide and harmful gases being directly discharged into the air; at the same time, it can avoid the heat released by the burning of red coke in the air being absorbed by the local coke guide grid for a long time, resulting in thinning of the wall thickness, reduced strength, deformation, and shortened service life.

[0015] In order to make the technical solution and beneficial effects of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.
[0016] Reference Figure 1 The embodiment of the utility model discloses a residual coke cleaning device at the tail of the coke guide grid of a coke intercepting vehicle, comprising a hydraulic station 4, one end of the hydraulic station 4 is connected to a control switch 1 arranged in the driving room of the coke intercepting vehicle through a control valve 3, the other end of the hydraulic oil pump 2 is connected to an oil cylinder 5 installed on the external working surface of the coke guide grid 9 through a hydraulic oil pipeline 8, the output end of the oil cylinder 5 is hinged with a support arm 6, one end of the support arm 6 is hinged to the external working surface of the coke guide grid 9, the other end of the support arm 6 extends to the coke guide grid 9 and is provided with a heat-resistant lining plate 7.
[0017] The output end of the oil cylinder 5 is hinged to the middle of the support arm 6. The support arm 6 is made of cast iron and has a strong high temperature resistance. The oil cylinder 5 and the support arm 6 are both installed outside the focus guide grid 9.
[0018] The oil cylinder 5 is connected to the hydraulic oil pump 2 on the hydraulic station 4 through the hydraulic oil pipeline 8, and the hydraulic station 4 provides power output. The control valve 3 is connected to and controls the hydraulic oil pump 2 on the hydraulic station 4. The control switch 1 of the control valve 3 is introduced into the cab of the coke intercepting vehicle, and the coke intercepting vehicle driver controls the cleaning action of the red coke at the tail of the coke guide grid.
[0019] When in use, after the coke pushing car completes the coke pushing task, the control switch 1 in the cab of the coke intercepting car sends an extension command, and the control valve 3 transmits the command to the hydraulic station 4 after receiving the command. The hydraulic station 4 controls the hydraulic oil pump 2 to work, and the hydraulic oil passes to the oil cylinder 5 through the hydraulic oil pipeline 8 to complete the extension action, thereby driving the support arm 6 to rotate around the hinge shaft, and then driving the heat-resistant bottom lining plate 7 to move and reach a tilted state, so that the red coke left at the tail of the coke guide grid 9 falls into the coke tank of the coke quenching car. After the red coke at the tail of the coke guide grid 9 falls, the control valve in the cab of the coke intercepting car sends a retraction command, which is transmitted to the oil cylinder 5 through the control valve 3 and the hydraulic oil pump 2 to complete the retraction action, and the heat-resistant bottom lining plate 7 returns to its original state and continues to receive the next furnace of red coke.
[0020] The support arm 6 can also be two upper and lower ones, one end of the support arm 6 is set in a hinge form, which can rotate, and the other end is used to fix the heat-resistant lining 7. The support arm 6 and the heat-resistant lining 7 are fixed with bolts for easy maintenance and replacement. The oil cylinder 5 and the hydraulic oil pipeline 8 are both coated with a high temperature resistant coating.
[0021] After the coke pushing car completes the coke pushing action, the driver of the coke blocking car can control this device to clean the remaining red coke at the tail of the coke guide grid and drop it into the coke tank of the coke quenching car, so as to avoid the red coke burning in the air and the generated carbon dioxide and harmful gases being directly discharged into the air; at the same time, it can prevent the heat released by the burning of red coke in the air from being absorbed by the local coke guide grid for a long time, resulting in thinning of the wall thickness, reduced strength, deformation, and shortened service life.
[0022] It should be understood that the specific embodiments described herein are only used to understand the present invention and are not used to limit the present invention. All other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the present invention.
