Description

Technical Field

[0001] The invention relates to the technical field of coke oven collection, in particular to a coke pusher side wall collection control system. Background Art

[0002] The state and temperature of the furnace wall affect the quality of the coke cake. During the coke pushing process, a wind-driven rotating collection lens is designed to achieve comprehensive collection of the coke cake front and the side of the furnace wall, which simplifies the structure and improves the comprehensiveness of collection. It is conducive to analyzing and adjusting the working state of the entire furnace chamber through software to ensure the quality of the coke cake.

[0003] Due to the narrow distance between the furnace walls, the collection area of ​​the lens when it is located in the middle of the furnace to collect data from the side walls is small. Therefore, in order to achieve comprehensive collection, multiple lenses need to be added. The movement stroke of the coke pushing rod is through the furnace body-through the coke guide grid-through the furnace body-initial position. A Chinese patent proposes a coke oven status collection system CN118109213B during the coke pushing process. The patent specification proposes that "as the coke pushing drive unit pushes the coke pushing unit to move, the distance between the image collection mechanism and the coke cake gradually increases until it is fixed. At the same time, the image collection mechanism rotates 90 degrees when it moves into the furnace, collects image information of the inner wall of the furnace wall, and obtains the temperature condition through software analysis. As the coke pushing unit is pushed to the coke guide grid, the image collection mechanism is away from the heat source point, so it can be known that the ambient temperature of the image collection mechanism changes from low temperature to high temperature to low temperature". However, when the length of the coke guide grid is less than or equal to the distance between the cooling tower and the coke cake contact plate, the cooling tower is located in the furnace at this time. At the same time, the coke pushing rod is also located in the furnace. At this time, the cooling medium is most affected by the external temperature, and the coke pushing rod itself begins to heat up seriously as the temperature in the furnace is transferred. In this case, the cooling effect of the low temperature-high temperature-low temperature method in the exit stage from the furnace is poor. Summary of the invention

[0004] The object of the present invention is to provide a focus pushing side wall acquisition control system to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0007] The pushing stroke remaining amount monitoring module monitors the movement remaining stroke of the pushing rod driven by the pushing driving assembly, and the pushing stroke remaining amount monitoring module records the remaining stroke max, the positive rotation remaining stroke and the remaining stroke min according to the remaining stroke, wherein the remaining stroke min is the limit movement stroke, and the remaining stroke min≥0;

[0008] The cooling tower is provided with two gas air inlets, and the two air inlets are respectively located at the top and the bottom of the cooling tower;

[0009] The pushing stroke remaining amount monitoring module controls the coke pushing car to move to the next coking furnace when the monitoring value reaches the remaining amount monitoring module, and the refrigerant supply module adjusts the wind speed, wind temperature and wind direction of the cooling tower according to the monitoring remaining amount monitoring module.

[0010] As a further solution of the present invention: before the residual stroke max reaches the positive rotation residual stroke, the refrigerant supply module increases the wind force to be able to drive the fixed fan blade module to drive the image acquisition module to rotate 90 degrees.

[0012] As a further solution of the present invention: when the pushing stroke remaining amount monitoring module monitors the change of the remaining amount from the remaining amount min to the positive rotation remaining amount stroke, the gas temperature of the refrigerant supply module maintains the lowest temperature and the wind speed remains unchanged until the remaining amount stroke max is reached, the gas temperature of the refrigerant supply module is reduced to the starting temperature, the wind speed gradually decreases, and the image acquisition module rotates and resets.

[0013] As a further solution of the present invention: the number of the fixed fan blade modules is two, and the fixed fan blade modules are rotatably connected to the upper and lower ends of the image acquisition module. The fixed fan blade modules are equipped with a locking structure fixedly connected to the image acquisition module, and the rotation directions of the two fixed fan blade modules are opposite. When the pushing stroke remaining amount monitoring module monitors the remaining amount to reach the remaining stroke min, the air inlet direction of the refrigerant supply module is converted from upper air inlet to lower air inlet, and the fixed fan blade module closest to the air inlet end in the cooling tower is locked with the image acquisition module, and the fixed fan blade module far away from the air inlet end of the cooling tower is separated from the image acquisition module and movably connected.

[0014] As a further solution of the present invention: the fixed fan blade module is replaced by the changing direction fan blade module, and the number of the changing direction fan blade modules is two and both are fixedly connected below the fixed fan blade module, the refrigerant supply module controls the air inlet direction of the cooling tower to remain unchanged but stops the air intake, and after the inclination angle of the blades of the changing direction fan blade module is changed, air enters the cooling tower and the image acquisition module is reversed.

[0015] As a further solution of the present invention: the distance between the cooling tower and the coke cake contact plate is L2, the length of the coke guide grid is L1, and L1 is equal to L2.

DETAILED DESCRIPTION

[0030] See also Figure 1-Figure 10 : In this embodiment: it includes a cooling tower 1 and a refrigerant supply module 300 arranged on the coke pushing rod 6, an image acquisition module 500 is rotatably connected in the cooling tower 1, the refrigerant supply module 300 uses gas as a heat exchange medium, and also includes a pushing stroke remaining amount monitoring module 100 and a fixed fan blade module 400. Three annularly distributed observation holes cooperating with the image acquisition module 500 are opened at the cooling tower 1. The rotation angle range of the image acquisition module 500 is 180 degrees, and the three observation holes correspond to the front and both sides of the coke pushing rod 6 respectively.

[0031] In this embodiment: First, the focus pushing component is introduced. Figure 2 The shaded parts in the middle are the furnace chamber 2 and the coke cake 3, respectively. The coke quenching car 5 and the coke pushing car 8 move on both sides of the furnace chamber 2, respectively. The coke pushing car 8 is provided with a coke pushing rod 6, and the bottom of the coke pushing rod 6 is a rack structure. A driving unit is arranged in the coke pushing car 8, and the driving unit drives the coke pushing rod 6 from one side of the furnace chamber 2 to push the coke cake 3 out from the other side. There is a distance between the coke quenching car 5 and the side wall of the furnace chamber 2, so the coke cake 3 needs to be transported to the car through the coke guide grid 4 for quenching treatment.

[0032] In this embodiment: the current problem is that the cooling tower can only be installed on the coke pushing rod 6, and the cooling tower needs to be located behind the coke cake contact plate 7. Therefore, the coke cake contact plate 7 enters the furnace chamber 2, but the actual cooling tower does not enter. Similarly, when the coke cake contact plate 7 comes out from the furnace door 9 on the other side, the cooling tower is still located in the furnace chamber 2.

[0033] In this embodiment: the present invention adopts a single complete collection on the same side, and uses the reciprocating motion of the focus push rod 6 to achieve the acquisition on the other side. This method is in line with practical applications and has a simple structure. The wind control method is adjusted to ensure that the image acquisition module 500 is in a safe environment.

[0034] In this embodiment: the cooling tower 1 is provided with three annularly distributed observation holes. In order to make 5 realize 180-degree rotation, the actual acquisition angles are respectively 0 degrees, 90 degrees, and 180 degrees. The corresponding positions are the left side, the front, and the right side, respectively collecting the left furnace wall, the surface of the coke cake 3, and the right furnace wall. The movement mode is to collect the front first, enter the furnace to collect the left furnace, and collect the right furnace out of the furnace. The entire image acquisition module 500 rotates in an integrated manner, and the wind drives the fixed fan blade module 400 to make the fixed fan blade module 400 spin and drive the image acquisition module 500 to rotate. However, the multiple lenses of the image acquisition module 500 of this embodiment are fixed in series and can be driven by a fixed fan blade module 400. During the rotation process, only the friction force needs to be considered, and the lens itself is small in size and light in weight, and the fixed fan blade module 400 can completely drive the image acquisition module 500 to rotate.

[0035] The pushing stroke remaining amount monitoring module 100 monitors the movement remaining stroke of the pushing driving assembly driving the pushing rod 6. The pushing stroke remaining amount monitoring module 100 records the remaining stroke max, the positive rotation remaining stroke and the remaining stroke min according to the remaining stroke, wherein the remaining stroke min is the limit movement stroke, and the remaining stroke min≥0;

[0036] In this embodiment: the refrigerant supply module 300 has an air supply unit and a cooling unit. The cooling unit is mainly used to cool the air blown out by the air supply unit. The air enters the interior of the cooling tower 1 through the internal air duct of the coke pusher 6. In order to simplify the control method, the control is carried out in the form of residual monitoring. For the specific principle, please refer to Figure 2 and Figure 5 Since the length of the coke pushing rod 6 is fixed, in order to reduce the cost, the length of the coke pushing rod 6 only needs to meet Figure 5 state, so in Figure 5 In this state, the residual stroke min ≥ 0, which is 0 in most states. A trigger block can also be set during the design process. When the trigger block contacts the end of the coke push rod 6, the residual stroke is 0. The trigger control method greatly reduces the stroke monitoring problem. The coke push rod 6 itself does not need high precision, so it is more suitable to adjust the target value within a large tolerance range. Similarly, the residual stroke max can be limited by the trigger limit block like the residual stroke min, without the need for precise length monitoring, and the mechanical design can fully meet the limit trigger requirements.

[0037] In this embodiment: Please refer to Figure 5, in the state of residual stroke min, the cooling tower 1 has completed a forward stroke of the length of the furnace wall movement. When reaching this position, the image acquisition module 500 needs to change direction to collect the other side to achieve comprehensive collection. The stroke between the residual stroke max and the positive rotation residual stroke is actually the tolerance stroke. At this stage, the cooling tower 1 is separated from the furnace body, the gas cooling intensity can be reduced, and the image acquisition module 500 can be adjusted in direction within this stroke. Since the displacement tolerance of this process is large, high-precision length detection is not required to meet the use requirements. And the residual length detection is located in the coke pushing car 8, which is more convenient for installation.

[0038] In this embodiment: the cooling tower 1 is provided with two gas air inlets, which are located at the top and the bottom of the cooling tower 1 respectively. The two air inlets can adjust the air inlet direction. When the upper air inlet is used, the lower air inlet is converted into an exhaust port, thereby realizing air circulation and cooling. A two-way air inlet duct is also provided for the subsequent two-way air inlet control of the image acquisition module 500.

[0039] In this embodiment: the pushing stroke remaining amount monitoring module 100 controls the coke pushing car 8 to move to the next coking furnace when the monitoring value reaches the remaining amount max, and the refrigerant supply module 300 adjusts the wind speed, wind temperature and wind direction of the cooling tower 1 according to the monitoring remaining amount of the pushing stroke remaining amount monitoring module 100.

[0040] In this embodiment: Please refer to Figure 2 In this stage, when the residual stroke is in the maximum state, the coke cake contact plate 7 faces the furnace door 9. At this time, the furnace door 9 is opened. When the furnace door 9 is opened, the image acquisition module 500 faces the front. A spring is provided in the rotating structure of the image acquisition module 500. The image acquisition module 500 can rotate 90 degrees to the left and right under the action of wind. Figure 2 In this state, the wind speed is low, the cooling tower 1 is cooled slowly, the wind force cannot act on the fixed blade module 400 to rotate the fixed blade module 400, and the image acquisition module 500 can capture the front of the coke cake 3.

[0041] In this embodiment: before the residual stroke max reaches the positive rotation residual stroke, the refrigerant supply module 300 increases the wind force to be able to drive the fixed blade module 400 to drive the image acquisition module 500 to rotate 90 degrees.

[0042] In this embodiment: Figure 2 and Figure 3Within the range, the remaining stroke changes, and the pushing stroke remaining stroke monitoring module 100 increases the wind speed to the point where the wind force can drive the fixed fan blade module 400 to drive the image acquisition module 500 to rotate 90 degrees when the remaining stroke max is reduced to the positive rotation remaining stroke range. The error range is very large, so high-precision monitoring is not required to meet the needs. Within the range between the remaining stroke max and the positive rotation remaining stroke, the cooling tower 1 does not enter the furnace body, so non-rotation does not affect the comprehensiveness of the acquisition.

[0043] In this embodiment: when the pushing stroke remaining amount monitoring module 100 monitors the remaining amount from the positive rotation remaining amount stroke to the remaining amount stroke min, the refrigerant supply module 300 adjusts the wind temperature, and when the remaining amount stroke of the pushing rod 6 reaches the remaining amount stroke min, the gas temperature of the refrigerant supply module 300 reaches the minimum temperature from the starting temperature.

[0044] In this embodiment: Please refer to Figure 4-Figure 5 In this stage, the time that the cooling tower 1 stays in the furnace gradually increases. In this process, the coke pushing rod 6 and the cooling tower are heating up, which gradually affects the internal temperature of the cooling tower 1. When the residual stroke min is reached, the distance of the coke pushing rod 6 in the furnace chamber 2 is the longest, and the temperature of the wind actually acting on the inside of the cooling tower 1 is high. Therefore, in this process, it is only necessary to monitor the positive rotation residual stroke to reduce the air supply temperature to the minimum when moving toward the residual stroke min.

[0045] In this embodiment: when the pushing stroke remaining amount monitoring module 100 monitors the remaining amount changing from the remaining amount min to the positive rotation remaining amount, the gas temperature of the refrigerant supply module 300 maintains the lowest temperature and the wind speed remains unchanged until the remaining amount max is reached, the gas temperature of the refrigerant supply module 300 drops to the starting temperature, the wind speed gradually decreases, and the image acquisition module 500 rotates and resets.

[0046] In the present embodiment, when the coke pushing rod 6 withdraws from the furnace chamber 2, although the length of the coke pushing rod 6 in the furnace gradually decreases, it is affected by the residence time at this time, and the residence time of the entire coke pushing component and the cooling tower 1 increases, resulting in a rapid temperature rise. Therefore, at this stage, the wind speed is kept constant under the lowest temperature state, thereby cooling the cooling tower 1 well.

[0047] In this embodiment: when the positive rotation residual stroke moves toward the residual stroke min, the cooling tower 1 is completely separated from the furnace chamber 2, and the temperature and wind speed are reduced, but the cooling tower is still in a cooling state. The actual movement speed of the coke pusher 6 is slow, so although the distance is short, it can still meet the cooling demand.

[0048] In the present embodiment: there are two fixed fan blade modules 400, and the fixed fan blade modules 400 are rotatably connected to the upper and lower ends of the image acquisition module 500. The fixed fan blade modules 400 are equipped with a locking structure fixedly connected to the image acquisition module 500. The rotation directions of the two fixed fan blade modules 400 are opposite. When the pushing stroke remaining amount monitoring module 100 monitors that the remaining amount reaches the remaining stroke min, the air inlet direction of the refrigerant supply module 300 is converted from the upper air inlet to the lower air inlet. The fixed fan blade module 400 closest to the air inlet end in the cooling tower 1 is locked with the image acquisition module 500, and the fixed fan blade module 400 far away from the air inlet end of the cooling tower 1 is separated from the image acquisition module 500 and movably connected.

[0049] In this embodiment: the fixed fan blade module 400 is a fixed fan blade. Since the fan blade will spin after being affected by the wind, the spin direction is related to the tilt direction of the fan blade. Since the two fixed fan blade modules 400 arranged above and below have opposite tilt directions, please refer to Fig.10 Left, this windward approach makes the connection pipe between the fixed blade module 400 at the bottom and the image acquisition module 500 in a fixed state, and the fixed blade module 400 at the top and the image acquisition module 500 in an active connection state, in which the image acquisition module 500 can be driven to rotate right. When the rotation margin stroke min is reached, refer to Fig.10 Right, at this time, the connection pipe of the upper fixed fan blade module 400 and the image acquisition module 500 is locked, and the lower fixed fan blade module 400 and the image acquisition module 500 are in an active state. At this time, the image acquisition module 500 rotates to the left, and the direction of the air inlet and outlet can be changed. The locking mechanism of the fixed fan blade module 400 and the image acquisition module 500 can be realized by an electromagnetic adsorption latch structure, etc. There are many connection methods and they are existing technologies, so they will not be repeated.

[0050] In the present embodiment: the fixed fan blade module 400 is replaced by a changing direction fan blade module 200, and the number of the changing direction fan blade modules 200 is two and both are fixedly connected below the fixed fan blade module 400, the refrigerant supply module 300 controls the air inlet direction of the cooling tower 1 to remain unchanged but stops the air intake, and after the inclination angle of the blades of the changing direction fan blade module 200 is changed, air enters the cooling tower 1, and the image acquisition module 500 is reversed.

[0051] In this embodiment, the direction of the image acquisition module 500 is regulated by using the direction-changing fan blade module 200 without changing the direction of the air inlet. Fig. 9 The blades of the changing direction fan blade module 200 are consistent with those of the fixed blade module 400. The difference is that the inclination direction of the blades of the changing direction fan blade module 200 can be controlled. By adjusting the inclination direction of the blades, the image acquisition module 500 can be reversed by only changing the inclination direction of the blades under the same air inlet direction.

[0052] In this embodiment, the distance between the cooling tower and the coke cake contact plate 7 is L2, the length of the focus guide grid 4 is L1, L1 is equal to L2, and the system is optimal when the distance between the cooling tower and the coke cake contact plate 7 is the same as the length of the focus guide grid 4.

[0053] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
