Description

Technical Field

[0001] The present application relates to the technical field of coke intercepting vehicles in coking plants, and in particular to a coke guide grid of a coke intercepting vehicle. Background Art

[0002] The coke blocking car is a supporting equipment for large coke ovens. It usually runs on the rails on the coke side of the coke oven. In the coking workshop, the coke blocking car serves the coke side of the coke oven and guides the red-hot coke pushed out of the charcoal chamber of the coke oven by the coke pushing car into the coke quenching car. The coke guide grid is the core mechanism of the coke blocking machine and is located in the middle of the coke blocking machine. When the coke side furnace door is opened, the coke pushing rod of the coke pushing machine pushes the high-temperature coke in the carbonization chamber into the coke guide grid, and the coke guide grid guides the pushed coke into the coke quenching car.

[0003] Due to the different thermal expansion of coke ovens and the deformation of the guide rails of the coke intercepting car, the distance between each furnace door and the joint surface of the coke guide grid may be different, so that the coke connection gap of the coke guide grid at each furnace mouth cannot be uniformly controlled. This makes the actual coke connection gap of some furnace mouths too large, causing a large amount of high-temperature coke smoke, dust and foam to erupt and leak from the coke connection gap of the coke guide grid, which not only seriously pollutes the environment, but also increases the workload of employees in dealing with the tail coke foam. Summary of the invention

[0004] In order to reduce the coke-joining gap between the coke guide grid and the joint surface of the furnace mouth, thereby reducing the leakage of pollutants such as coke smoke and enhancing environmental protection, the present application provides a coke guide grid for a coke intercepting car.

[0005] The present application provides a coke guide grid for a coke intercepting vehicle using the following technical solution: A focus guide grid of a focus intercepting car comprises a focus intercepting car and a focus guide grid, wherein a track is arranged on the upper portion of the focus intercepting car, a suspension roller which slides on the track is connected to the focus guide grid, and the focus intercepting car is provided with a driving mechanism for driving the focus grid to move; a compensation plate is slidably arranged on the side wall of the focus guide grid close to one end of a furnace opening, a high-temperature asbestos cloth is detachably connected to the compensation plate, the high-temperature asbestos cloth abuts against the side wall of the furnace opening, a moving component for driving the compensation plate to move is arranged on the focus guide grid, and a dust removal device for removing dust is provided on the focus intercepting car.

[0006] By adopting the above technical solution, when the gap between the coke guide grid and the furnace mouth is too large, the staff drives the compensation plate to move toward the furnace mouth through the moving component until it abuts against the side wall of the furnace mouth, thereby reducing the gap between the coke guide grid and the furnace mouth. The high-temperature asbestos cloth has the characteristics of high temperature resistance and softness, and can be attached to the side wall of the furnace mouth, thereby strengthening the prevention of coke smoke, dust, and powder from erupting and leaking from the coke guide grid gap, reducing environmental pollution. At the same time, a dust removal device is arranged outside the furnace mouth, which can absorb and process the dust overflowing from the high-temperature asbestos cloth, thereby strengthening environmental protection.

[0007] Preferably, the high-temperature asbestos cloth is provided with multiple layers, and pressure plates for fixing the multiple layers of the high-temperature asbestos cloth are respectively provided at both ends of the high-temperature asbestos cloth, and a replacement mechanism for replacing the high-temperature asbestos cloth is provided on the compensation plate.

[0008] By adopting the above technical solution, multiple layers of high-temperature asbestos cloth can improve the sealing effect of the furnace mouth. However, if the high-temperature asbestos cloth is exposed to a high-temperature and dusty environment for a long time, its internal fiber structure may change, resulting in reduced fireproof performance. Therefore, the staff can replace the high-temperature asbestos cloth through a replacement mechanism to maintain the sealing effect of the furnace mouth.

[0009] Preferably, the moving assembly includes a first motor, a first screw and a slider, a fixed block is fixedly connected to the outer wall of the focus guide grid, the first screw is rotatably connected to the fixed block, the first motor is fixedly connected to the fixed block, one end of the first screw is fixedly connected to the rotating shaft of the first motor, the slider is fixedly connected to the side wall of the compensation plate, and the first screw is threadedly connected to the slider.

[0010] By adopting the above technical solution, when the staff needs to extend the compensation plate to abut against the furnace mouth, the staff starts the first motor, the rotation of the first motor drives the first screw to rotate, and the rotation of the first screw drives the compensation plate to move toward the furnace mouth until it abuts against the side wall of the furnace mouth.

[0011] Preferably, the walls surrounding the port of the focus guide grille close to one end of the furnace opening are all provided with inclined surfaces, and the inclined surfaces slide relatively on the inner wall of the compensation plate.

[0012] By adopting the above technical solution, when the compensation plate is extended to abut against the furnace mouth, when the red coke passes through the compensation plate and enters the focus guide grid, the inclination of the side wall at the port connected to the compensation plate can reduce the resistance of the red coke entering the focus guide grid, thereby reducing the thrust of the red coke on the focus guide grid, and further reducing the possibility of the focus guide grid being offset due to the thrust of the red coke.

[0013] Preferably, the focus guide grid includes an inner wall and an outer wall, cooling pipes are arranged between the inner wall and the outer wall, an input port and an output port are provided at one end of the focus guide grid away from the furnace mouth, a water tank is provided on the focus intercepting car, and the water tank and the input port and the output port are all connected through water pipes.

[0014] By adopting the above technical solution, when the coke pusher pushes the red coke to the coke guide grid, the water in the water tank circulates through the cooling pipe, thereby absorbing part of the heat emitted by the hot coke, slowing down the speed at which the temperature of the inner wall is transferred to the outer wall, lowering the temperature of the outer wall, and thereby reducing the impact on the first motor and other electrical components on the outer wall, and can also reduce high temperature injuries caused by accidental contact by staff.

[0015] Preferably, the replacement mechanism includes two connecting plates, which are respectively fixedly connected to the two side walls of the compensation plate, and the connecting plates are provided with plug-in grooves, the high-temperature asbestos cloth is inserted into the plug-in groove, and the pressure plate is inserted into the connecting plates; a sliding groove is provided in the connecting plate, a stop block is slidable in the sliding groove, a spring is provided in the sliding groove, two ends of the spring are respectively fixedly connected to the stop block and the inner wall of the sliding groove, an inclined surface is provided on the stop block, the pressure plate abuts against the inclined surface, and a fixing component for fixing the high-temperature asbestos cloth is provided in the connecting plate.

[0016] By adopting the above technical solution, although the high-temperature asbestos cloth has the characteristics of high temperature resistance, its fiber structure may change after long-term use in a high-temperature environment, resulting in reduced fireproof performance. Therefore, in a long-term high-temperature environment, the high-temperature asbestos cloth should be regularly inspected and replaced in time; when the staff replaces the high-temperature asbestos cloth, the staff first releases the fixing effect of the fixing component on the high-temperature asbestos cloth, and then removes the old high-temperature asbestos cloth from the connecting plate, and inserts the new high-temperature asbestos cloth into the connecting plate. During the process, the pressure plate abuts against the inclined surface of the block and pushes the block compression spring to move. When the pressure plate passes over the block, the block abuts against the high-temperature asbestos cloth under the push of the spring, thereby pre-fixing the high-temperature asbestos cloth, which is convenient for adjusting the position of the high-temperature asbestos cloth. Subsequently, the staff strengthens the fixation of the high-temperature asbestos cloth through the fixing component.

[0017] Preferably, the fixing assembly includes a pressure plate and a cylinder, the pressure plate slides in the connecting plate, the pistons of the plurality of cylinders are respectively fixedly connected to the pressure plate at different height positions, the outer wall of the compensation plate is provided with a recessed groove, the pressure plate abuts against the high-temperature asbestos cloth and presses against the inner wall of the recessed groove.

[0018] By adopting the above technical solution, after the staff adjusts the position of the high-temperature asbestos cloth, the staff starts the cylinder, and the piston of the cylinder pushes the pressure plate to abut against the high-temperature asbestos cloth so that the high-temperature asbestos cloth abuts against the inner wall of the recessed groove, thereby limiting the position of the high-temperature asbestos cloth, and the recessed groove can strengthen the fixation of the high-temperature asbestos cloth.

[0019] Preferably, the dust removal device includes a vacuum cleaner, a vacuum pipe and a first vacuum hood, the first vacuum hood is fixedly connected to the side wall of the focus guide grid, the vacuum cleaner is installed on the focus intercepting vehicle, and the first vacuum hood is connected to the vacuum cleaner through the vacuum pipe.

[0020] By adopting the above technical solution, the smoke and dust overflowing from the furnace mouth through the high-temperature asbestos cloth is absorbed by the first dust hood, thereby reducing the emission of dust, thereby reducing the cleaning work of the staff and reducing environmental pollution, and maintaining the health of the staff.

[0021] Preferably, the dust removal device further comprises a blower and a pipeline, an air outlet is provided in the track, the blower is installed on the coke intercepting car, and the blower is connected to the air outlet through a pipeline.

[0022] By adopting the above technical solution, the air blast port can blow out the dust that has fallen into the track, thereby reducing the dust accumulation on the track and affecting the movement of the suspension roller.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the gap between the coke guide grid and the furnace mouth is too large, the staff drives the compensation plate to move closer to the furnace mouth through the moving assembly until it abuts against the side wall of the furnace mouth, thereby reducing the gap between the coke guide grid and the furnace mouth. The high-temperature asbestos cloth has the characteristics of high temperature resistance and softness, and can be attached to the side wall of the furnace mouth, thereby strengthening the prevention of coke smoke, dust, and powder from erupting and leaking from the gap between the coke guide grid and the coke, thereby reducing environmental pollution. At the same time, a dust removal device is provided outside the furnace mouth, which can absorb and process the dust overflowing from the high-temperature asbestos cloth, thereby strengthening environmental protection; 2. Multiple layers of high-temperature asbestos cloth can improve the sealing effect of the furnace mouth, but if the high-temperature asbestos cloth is in a high-temperature and dusty environment for a long time, its internal fiber structure may change, resulting in reduced fireproof performance. Therefore, the staff can replace the high-temperature asbestos cloth through the replacement mechanism to maintain the sealing effect of the furnace mouth; 3. When the compensation plate is extended and abuts against the furnace mouth, when the red coke passes through the compensation plate and enters the focus guide grid, the inclination of the side wall at the port connected to the compensation plate can reduce the resistance of the red coke entering the focus guide grid, thereby reducing the thrust of the red coke on the focus guide grid, and further reducing the possibility of the focus guide grid being offset due to the thrust of the red coke.

[0031] The following is combined with Figure 1-6 This application is described in further detail.

[0032] The embodiment of the present application discloses a coke guide grid 2 of a coke intercepting vehicle 1, such as Figure 1 and Figure 2 As shown, it includes a coke intercepting car 1 and a coke guide grid 2. A track 3 is arranged on the upper part of the coke intercepting car 1. A hanging roller 4 sliding on the track 3 is connected to the upper end of the coke guide grid 2. A driving mechanism for driving the coke grid to move is arranged on the coke intercepting car 1. A compensation plate 5 is slidingly arranged on the side wall of the coke guide grid 2 near the furnace mouth. The cross section of the compensation plate 5 is a rectangular frame. A moving component 7 for driving the compensation plate 5 to move is arranged on the coke guide grid 2. A dust removal device 8 for dust removal is arranged on the coke intercepting car 1. A high-temperature asbestos cloth 6 is detachably connected to the end of the compensation plate 5 near the furnace mouth. The high-temperature asbestos cloth 6 abuts against the side wall of the furnace mouth. The high-temperature asbestos cloth 6 is arranged in multiple layers, and pressure plates 9 for compacting and fixing multiple layers of the high-temperature asbestos cloth 6 are respectively arranged at both ends of the high-temperature asbestos cloth 6. A replacement mechanism 10 for replacing the high-temperature asbestos cloth 6 is arranged on the compensation plate 5. When the gap between the coke guide grid 2 and the furnace mouth is too large, the staff drives the compensation plate 5 to move toward the furnace mouth through the moving component 7 until it abuts against the side wall of the furnace mouth, thereby reducing the gap between the coke guide grid 2 and the furnace mouth. The high-temperature asbestos cloth 6 has the characteristics of high temperature resistance and softness, and can be attached to the side wall of the furnace mouth. Multiple layers of high-temperature asbestos cloth 6 can enhance the sealing effect of the furnace mouth, thereby strengthening the prevention of coke smoke, dust, and powder from erupting and leaking from the coke gap of the coke guide grid 2, reducing environmental pollution. At the same time, a dust removal device 8 is arranged outside the furnace mouth, which can absorb and process the dust overflowing from the high-temperature asbestos cloth 6, thereby strengthening environmental protection.

[0033] like Figure 1 and Figure 3As shown, the dust removal device 8 includes two dust collectors 31, a first dust hood 33 and a dust pipe 32. The two first dust hoods 33 are respectively connected to the side walls of the coke guide grid 2, and the first dust hood 33 faces the furnace mouth. The dust collector 31 is installed on the coke intercepting car 1, and the first dust hood 33 is connected to the dust collector 31 through the dust pipe 32. Therefore, the smoke and dust overflowing from the furnace mouth through the high-temperature asbestos cloth 6 are absorbed by the first dust hood 33, thereby reducing the dust from being emitted outward. The dust removal device 8 also includes a blower 34 and a pipeline. An air blast 35 is provided in one end of the track 3 away from the furnace mouth. The blower 34 is installed on the coke intercepting car 1. The control console in the operating room controls the dust collector 31 and the blower 34. The blower 34 is connected to the air blast 35 through a pipeline. The air blast 35 blows the dust in the track 3 out of the track 3, thereby reducing the dust from entering the track 3, thereby reducing the dust accumulation on the track 3 and affecting the movement of the hanging roller 4.

[0034] like Figure 4 As shown, the moving assembly 7 is provided with two groups, which are respectively located on both sides of the compensation plate 5. The moving assembly 7 includes a first motor 11, a first screw rod 12 and a slider 13. The outer walls of both sides of the focus guide grid 2 are fixedly connected with fixed blocks, and the fixed blocks include a fixed block 14 and a fixed block 2 15. The fixed block 14 and the fixed block 2 15 are welded to the outer wall of the focus guide grid 2 along the same horizontal line. The first screw rod 12 is penetrated and rotatably connected to the fixed block 14 and the fixed block 2 15. The first motor 11 is fixedly installed on the fixed block 2 15, so that the first motor 11 can be kept away from the wall of the focus guide grid 2 to avoid the wall of the focus guide grid 2 directly transferring the temperature to the first motor 11 during the focusing process. One end of the first screw rod 12 is fixedly welded to the rotating shaft of the first motor 11, and the slider 13 is fixedly welded to the side wall of the compensation plate 5. The first screw rod 12 is threadedly connected to the slider 13. When the staff needs to extend the compensation plate 5 to abut against the furnace mouth, the staff starts the two first motors 11 at the same time in the operating room of the coke intercepting car 1. The rotation of the first motor 11 drives the first screw rod 12 to rotate. The rotation of the first screw rod 12 drives the compensation plate 5 to move toward the furnace mouth until it abuts against the side wall of the furnace mouth.

[0035] like Figure 1 and Figure 4As shown, the coke guide grid 2 includes an inner wall 17 and an outer wall 18, a cooling pipe 19 is arranged between the inner wall 17 and the outer wall 18, an input port 21 and an output port 22 are arranged at the end of the coke guide grid 2 away from the furnace mouth, and water tanks 20 are respectively arranged on both sides of the coke guide grid 2 on the coke intercepting car 1, and the water tank 20 is connected to the input port 21 and the output port 22 on the coke guide grid 2 on the same side through water pipes, and a water pump for driving water flow is arranged in the water tank 20. When the coke pushing car pushes the red coke to the coke guide grid 2, the water in the water tank 20 circulates through the cooling pipe 19, thereby absorbing part of the heat emitted by the hot coke, slowing down the speed of the temperature of the inner wall 17 being transferred to the outer wall 18, reducing the temperature of the outer wall 18, and then reducing the impact on the first motor 11 and other electrical components on the outer wall 18, and can also reduce the high temperature damage caused by accidental contact of the staff.

[0036] like Figure 4 and Figure 5As shown, the replacement mechanism 10 includes two connecting plates 23, which are C-shaped. The top ends of the two connecting plates 23 are respectively fixedly welded to the upper end surfaces on both sides of the compensation plate 5. The connecting plates 23 are provided with plug-in grooves 36, and the high-temperature asbestos cloth 6 is inserted into the plug-in grooves 36. The connecting plates 23 are provided with slide grooves 24, and a stopper 25 is slidable in the slide groove 24. A plurality of springs 26 are arranged in the slide groove 24. The springs 26 are arranged in the horizontal direction and their two ends are respectively fixedly welded to the stopper 25 and the inner wall of the slide groove 24. The stopper 25 is provided with an inclined surface 27, and the pressure plate 9 abuts against the inclined surface 27 and is inserted into the connecting plate 23; a fixing component 28 for fixing the high-temperature asbestos cloth 6 is arranged in the connecting plate 23. The fixing assembly 28 includes a pressure plate 29 and a plurality of cylinders 30. The pressure plate 29 slides in the plug-in slot 36. The pistons of the plurality of cylinders 30 are respectively fixed and welded at different height positions of the pressure plate 29. The outer wall of the compensation plate 5 is provided with a recessed slot. The pressure plate 29 abuts against the high-temperature asbestos cloth 6 and abuts against the inner wall of the recessed slot. Although the high-temperature asbestos cloth 6 has the characteristics of high temperature resistance, its fiber structure may change after long-term use in a high-temperature environment, resulting in reduced fireproof performance. Therefore, in a long-term high-temperature environment, the high-temperature asbestos cloth 6 should be regularly inspected and replaced in time; when the staff replaces the high-temperature asbestos cloth 6, the staff first uses the cylinder 30 to move the pressure plate 29 away from the high-temperature asbestos cloth 6, and then pushes the block 25 to compress the spring 26 in the slide slot 24, and then takes out the old high-temperature asbestos cloth 6 from the plug-in slot 36. After that, when inserting the new high-temperature asbestos cloth 6 into the insertion slot 36 on the connecting plate 23, the staff drives the pressing plate 9 to move to abut against the inclined surface 27 on the abutment block 25, and pushes the abutment block 25 to compress the spring 26 to move, so that after the pressing plate 9 passes over the abutment block 25, the abutment block 25 abuts against the high-temperature asbestos cloth 6 under the action of the spring 26, thereby pre-fixing the high-temperature asbestos cloth 6, which is convenient for the staff to adjust the high-temperature asbestos cloth 6. The staff can rotate the pressing plate 9 to roll up the high-temperature asbestos cloth 6 to adjust the position of the high-temperature asbestos cloth 6, so that the opening on the high-temperature asbestos cloth 6 is aligned with the opening of the compensation plate 5. When the staff adjusts the position of the high-temperature asbestos cloth 6, the staff starts the cylinder 30, and the piston of the cylinder 30 pushes the pressure plate 29 to abut against the high-temperature asbestos cloth 6 so that the high-temperature asbestos cloth 6 abuts against the inner wall of the concave groove, thereby limiting the position of the high-temperature asbestos cloth 6, and the concave groove can strengthen the fixation of the high-temperature asbestos cloth 6.

[0037] like Figure 6 As shown, the walls around the port of the focus guide grille 2 near the furnace mouth are all provided with inclined surfaces 2716, and the inclined surfaces 2716 slide relatively on the inner wall of the compensation plate 5. When the compensation plate 5 is extended to abut against the furnace mouth, when the red coke passes through the compensation plate 5 and enters the focus guide grille 2, the inclination of the side wall at the port connected to the compensation plate 5 can reduce the resistance of the red coke entering the focus guide grille 2, thereby reducing the thrust of the red coke on the focus guide grille 2, and further reducing the possibility of the focus guide grille 2 being deflected due to the thrust of the red coke.

[0038] The implementation principle of the embodiment of the present application is: when the joint surface between the furnace door and the coke guide grid 2 does not fit, and the gap between the coke guide grid 2 and the furnace mouth is too large, the staff drives the compensation plate 5 to move toward the furnace mouth through the moving component 7 until it abuts against the side wall of the furnace mouth, thereby reducing the gap between the coke guide grid 2 and the furnace mouth. The high-temperature asbestos cloth 6 has the characteristics of high temperature resistance and softness, and can fit on the side wall of the furnace mouth, thereby strengthening the prevention of coke smoke, dust, and powder from erupting and leaking from the coke guide grid 2 gap, reducing environmental pollution. At the same time, a dust removal device 8 is provided outside the furnace mouth, which can absorb and process the dust overflowing from the high-temperature asbestos cloth 6, thereby strengthening environmental protection.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
