Description
Technical Field
[0001] This invention relates to the field of metallurgical technology, and in particular to a method, apparatus, equipment and medium for replacing the flip-top of a coke oven dust collector. Background Technology
[0002] A coke oven is a large-scale, single-hole, intermittent, continuous thermal reactor. The coking process includes charge loading, carbonization, and coke pushing. The coke pushing process involves using a coke pusher car to push the matured coke out of the carbonization chamber and then using a coke quenching car to guide the red-hot coke into the quenching car tank. This process generates a large amount of smoke and dust, polluting the environment. Therefore, it is necessary to collect the smoke and dust generated during the coke pushing process.
[0003] Because coke ovens are characterized by intermittent single-hole operation and continuous operation throughout the entire oven, the coke oven dust collector uses a structure where one main unit corresponds to multiple air intakes to achieve dust removal. There are nearly a hundred sealing valves on the air intake pipe corresponding to the coke oven holes. The sealing performance of these valves is crucial to the operation of the dust collector. To ensure the efficient use of the dust collector, the valves and their components need to be replaced regularly.
[0004] However, in related technologies, replacing the flip cover of the switch requires shutting down the entire dust collector equipment, and it can only be restarted after the flip cover is replaced, resulting in low coke oven production efficiency. Therefore, how to replace the flip cover of the switch online is an urgent problem to be solved. Summary of the Invention
[0005] This application provides a method, apparatus, equipment, and medium for replacing the flip cover of a coke oven dust collector. It solves the technical problem in the prior art that when replacing the flip cover of the opener, the entire dust collector equipment needs to be stopped and the equipment can only be opened after the flip cover is replaced, which leads to low coke oven production efficiency. This application achieves the technical effect of replacing the flip cover during the operation of the dust collector, thereby improving the coke oven production efficiency.
[0006] In a first aspect, this application provides a method for replacing the flip-top of a coke oven dust collector, the method comprising:
[0007] In response to a replacement request for the flap to be replaced in the target suction pipe of the coke oven dust collector, the actual pressure in the target suction pipe is monitored.

[0009] Control the crank arm to lift, and install the target new flip plate on the crank arm;
[0010] After the flap to be replaced is separated from the crank arm, when the actual pressure is less than the second target pressure, the flap to be replaced is separated from the target air intake pipe, and the crank arm is controlled to carry the new target flap down, so that the new target flap is sealed on the target air intake pipe; the second target pressure is less than or equal to the first target pressure.

[0019] Furthermore, determining whether the estimated replacement time between the flap to be replaced and the target new flap is less than the coke oven discharge interval time of the coke oven where the coke oven dust collector is located includes:
[0020] Obtain the travel distance and pulling force of the target device pulling the flap to be replaced from the target suction pipe, and estimate the negative pressure generated by the target suction pipe on the flap to be replaced;
[0021] Based on the travel distance, tension, and negative pressure, estimate the estimated replacement time for the target equipment to remove the flap to be replaced from the target suction pipe;
[0022] Based on the estimated replacement time and the coke oven coke discharge interval, determine whether the estimated replacement time between the flap to be replaced and the target new flap is less than the coke oven coke discharge interval where the coke oven dust collector is located.
[0023] Further, the flap to be replaced is separated from the target inhalation tube, including:
[0024] The flap to be replaced is pulled horizontally away from the target device, thus separating it from the target suction tube; or,
[0025] The target device is used to pull the flap to be replaced away along the normal direction of the flap to be replaced, so that the flap to be replaced is separated from the target air inlet pipe.
[0026] Furthermore, monitor the actual pressure in the target inhalation tube, including:
[0027] Obtain the actual pressure displayed on the target inhalation tube;

[0030] Secondly, this application provides a flip-top replacement device for a coke oven dust collector, the device comprising:
[0031] The pressure monitoring module is used to monitor the actual pressure in the target suction pipe in response to the replacement request of the flap to be replaced in the target suction pipe of the coke oven dust collector.
[0032] The dismantling module is used to remove the connecting parts that connect the flap to be replaced and the crank arm when the actual pressure exceeds the first target pressure, so that the flap to be replaced is held on the target intake pipe by friction.
[0033] Install a control module to control the lifting of the crank arm and install the target new flip plate on the crank arm;

[0040] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0041] This embodiment first determines the state between the flap to be replaced and the target suction pipe to see if the flap can be replaced online. If online replacement is possible, a replacement request is generated. The actual pressure in the target suction pipe is monitored. When the actual pressure exceeds a first target pressure, the connecting component between the flap to be replaced and the crank arm is removed, allowing the flap to be replaced to be held on the target suction pipe by friction. Then, the crank arm is raised, and a new target flap is installed on the crank arm. When the actual pressure is less than a second target pressure, the flap to be replaced is separated from the target suction pipe, and the crank arm is lowered carrying the new target flap, sealing it onto the target suction pipe. Thus, this embodiment utilizes the suction force of the target suction pipe itself on the flap to be replaced to achieve the reverse installation steps of "first fixing the new target flap, then removing the flap to be replaced, and finally installing the new target flap onto the target suction pipe." This allows for safe, fast, and online replacement of the flap on the coke oven, thereby reducing downtime for equipment such as coke ovens and improving production efficiency.

[0053] This application provides a method for replacing the flip cover of a coke oven dust collector, which solves the technical problem in the prior art where the entire dust collector needs to be stopped and restarted after the flip cover is replaced, resulting in low coke oven production efficiency.
[0054] The technical solution of this application embodiment is to solve the above-mentioned technical problems, and the general idea is as follows:
[0055] A method for replacing the flap of a coke oven dust collector includes: in response to a replacement request for a flap 2 to be replaced on a target suction pipe 1 in the coke oven dust collector, monitoring the actual pressure in the target suction pipe 1; when the actual pressure exceeds a first target pressure, removing the connecting component 4 that connects the flap 2 to be replaced to a crank arm 3, so that the flap 2 to be replaced is held on the target suction pipe 1 by friction; controlling the crank arm 3 to lift, and installing a new target flap 7 on the crank arm 3; after the flap 2 to be replaced is separated from the crank arm 3, when the actual pressure is less than a second target pressure, separating the flap 2 to be replaced from the target suction pipe 1, and controlling the crank arm 3 to lower the new target flap 7, so that the new target flap 7 is sealed on the target suction pipe 1; the second target pressure is less than or equal to the first target pressure.
[0056] This embodiment utilizes the suction force of the target suction pipe 1 on the flip plate 2 to achieve the reverse installation steps of "first fixing the target new flip plate 7, then removing the flip plate 2 to be replaced, and finally installing the target new flip plate 7 onto the target suction pipe 1". This can safely, quickly and online realize the replacement of the flip plate 2 on the coke oven, thereby reducing the downtime of equipment such as coke ovens and improving production efficiency.
[0057] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0058] First, it should be clarified that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.
[0059] This embodiment provides, for example Figure 1 The method shown is a method for replacing the flip cover of a coke oven dust collector, which includes steps S11-S14.
[0060] Step S11: In response to the replacement request of the replacement flap 2 of the target suction pipe 1 in the coke oven dust collector, monitor the actual pressure in the target suction pipe 1.
[0061] Step S12: When the actual pressure exceeds the first target pressure, remove the connecting part 4 used to connect the flap to be replaced 2 and the crank arm 3, so that the flap to be replaced 2 is held on the target suction pipe 1 by friction.
[0062] Step S13: Control the crank arm 3 to lift up and install the target new flip plate 7 on the crank arm 3;
[0063] Step S14: After the replacement flap 2 is separated from the crank arm 3, when the actual pressure is less than the second target pressure, the replacement flap 2 is separated from the target suction pipe 1, and the crank arm 3 is controlled to carry the target new flap 7 down, so that the target new flap 7 is sealed on the target suction pipe 1; the second target pressure is less than or equal to the first target pressure.
[0064] In the Figure 1 Before describing the method for replacing the flip-top of the coke oven dust collector shown, this embodiment will first combine... Figure 2 The structural relationship between the target air intake pipe 1, the crank arm 3, and the flap to be replaced 2 is described.
[0065] Target suction pipe 1 is any one of the many suction pipes in the coke oven dust collector that requires replacement of the flap. For example... Figure 2 As shown, the hole on the target air intake tube 1 is sealed by the replacement flap 2, which is connected to the crank arm 3 via a connecting component 4 (e.g., a pin); a push plate 5 is also connected to the crank arm 3, and by applying force to the push plate 5, the crank arm 3 can be rotated.
[0066] Now combined Figure 2 The schematic diagram shown depicts the target inhalation tube 1 and the flap 2 to be replaced. Figure 1The method for replacing the flip panel shown is explained.
[0067] Regarding step S11, in response to the replacement request of the flap 2 to be replaced in the target suction pipe 1 in the coke oven dust collector, the actual pressure in the target suction pipe 1 is monitored.
[0068] The method for generating a replacement request for the flap 2 to be replaced in the target suction pipe 1 of the coke oven dust collector includes steps S111-S113.
[0069] Step S111: Determine whether the flap 2 to be replaced can be maintained on the target suction pipe 1 by friction.
[0070] Step S112: Determine whether the estimated replacement time of the flap 2 to be replaced and the target new flap 7 is less than the coke oven discharge interval time of the coke oven dust collector.
[0071] Step S113: When the flap 2 to be replaced can be maintained on the target suction pipe 1 by friction and the estimated replacement time is less than the coke oven coking interval time, a replacement request is generated and responded to.
[0072] Steps S111 and S112 are two conditions for generating a replacement request. The judgment process for these two conditions will now be explained. Steps S111 and S112 can be implemented simultaneously or sequentially. It should be noted that during the execution of steps S111 and / or S112, the actual operation of the flip-board 2 to be replaced is not involved; the replacement process is simulated through data calculation. Only after both conditions in steps S111 and S112 are met, and a replacement request is obtained, will the flip-board 2 to be replaced enter the actual replacement process. That is, steps S12-S14 are the steps involved in the actual replacement process of the flip-board 2 to be replaced.
[0073] Regarding step S111, which is to determine whether the flap 2 to be replaced can be maintained on the target air intake pipe 1 by friction, it includes steps S1111-S1113.
[0074] Step S1111: Obtain the actual weight of the flap 2 to be replaced, obtain the actual tilt angle of the flap 2 to be replaced installed on the target air intake pipe 1, obtain the actual friction coefficient between the target air intake pipe 1 and the flap 2 to be replaced, and obtain the actual coverage area of the target air intake pipe 1 on the flap 2 to be replaced.
[0075] Step S1112: Based on the actual weight, actual tilt angle, actual friction coefficient, and actual coverage area, determine the minimum positive pressure that the flap to be replaced 2 maintains on the target air intake pipe 1 by relying on friction.
[0076] Step S1113: Based on whether the minimum positive pressure is within the target preset pressure range corresponding to the target air intake pipe 1, determine whether the flap 2 to be replaced can be maintained on the target air intake pipe 1 by friction.
[0077] Regarding step S1111, generally speaking, flip-boards made of the same material have basically the same weight, while flip-boards made of different materials will have different weights. Therefore, in actual operation, the actual weight of the flip-board 2 to be replaced can be determined by the correspondence between the flip-board material and weight, or its actual weight can be calculated in real time based on the material, material parameters, volume, etc. of the flip-board 2 to be replaced.
[0078] like Figure 2 As shown, the flap 2 to be replaced has an angle with both the horizontal direction and the horizontal direction, specifically as follows: Figure 3 As shown, the angle between the flap 2 to be replaced and the horizontal direction is θ, which is the actual tilt angle. The actual tilt angle can be obtained through on-site measurement.
[0079] The actual coefficient of friction between the target suction pipe 1 and the flap 2 to be replaced can be determined based on the material parameters of the contact surfaces of the target suction pipe 1 and the flap 2 to be replaced.
[0080] The actual coverage area of the target inhalation tube 1 on the flap 2 to be replaced can be the actual area covered by the outer diameter of the target inhalation tube 1 on the flap 2 to be replaced, which can be calculated based on the outer diameter of the target inhalation tube 1.
[0081] Regarding step S1112, the replacement process of the flap 2 provided in this embodiment relies on the negative pressure of the target inhalation pipe 1 on the flap 2 and the friction between the flap 2 and the target inhalation pipe 1, so that the flap 2 can be maintained on the target inhalation pipe 1 without relying on external forces. In order to determine whether the flap 2 can be maintained on the target inhalation pipe 1 by relying on friction, it is necessary to calculate the minimum positive pressure corresponding to the flap 2 being maintained on the target inhalation pipe 1 by friction.
[0082] like Figure 3 The diagram shows the force analysis when the flap to be replaced 2 covers the target air intake pipe 1 by friction alone. M is the actual weight, g is the acceleration due to gravity, μ is the coefficient of friction, S is the actual coverage area, Pv is the negative pressure generated by the target air intake pipe 1 on the flap to be replaced 2, and θ is the actual tilt angle.
[0083] The minimum positive pressure in step S1112 is Figure 3 The pressure corresponding to the minimum Pv can be calculated using Formula 1.
[0084] Pv=m×g×(sinθ-u×cosθ)÷(u×S) Formula 1
[0085] Regarding step S1113, the target preset pressure range corresponding to the target suction pipe 1 refers to the pressure range consisting of the lowest and highest pressures of the coke oven dust collector during operation. In this embodiment, Pmin represents the lowest pressure and Pmax represents the highest pressure. When Pv is greater than Pmin and less than Pmax, it is considered that the minimum pressure maintained by the friction force on the target suction pipe 1 by the flap 2 to be replaced is within the normal operating pressure range of the target suction pipe 1, thus satisfying one of the conditions for generating a replacement request.
[0086] When Pv is greater than Pmin and less than Pmax, it is considered that the minimum pressure maintained by friction on the target air intake pipe 1 by the flap 2 to be replaced is within the normal working pressure range of the target air intake pipe 1, thus satisfying one of the conditions for generating a replacement request.
[0087] When Pv is less than Pmin, it can be considered as meeting one of the conditions for generating a replacement request in principle. However, this situation usually does not exist. Therefore, in actual operation, it can be determined according to the actual situation to determine whether this situation meets one of the conditions for generating a replacement request.
[0088] When Pv is greater than Pmax, it is considered that the flap 2 to be replaced cannot be maintained on the target air intake pipe 1 by friction even when the target air intake pipe 1 provides the maximum negative pressure, and thus does not meet one of the conditions for generating a replacement request.
[0089] When steps S111 and S112 are executed sequentially, if it is determined that the flap 2 to be replaced cannot be maintained on the target air intake pipe 1 by friction even when the target air intake pipe 1 provides the maximum negative pressure, then step S112 can be skipped, and a prompt message indicating that the flap cannot be replaced online can be directly output. This can save computing resources and shorten the waiting time, so that the operator can perform the manual replacement of the flap as soon as possible.
[0090] Regarding step S112, it is determined whether the estimated replacement time between the flap 2 to be replaced and the target new flap 7 is less than the coke oven discharge interval time of the coke oven dust collector, including steps S1121-S1123.
[0091] Step S1121: Obtain the travel distance and pulling force of the target device pulling the flap to be replaced 2 from the target suction pipe 1, and estimate the negative pressure generated by the target suction pipe 1 on the flap to be replaced 2.
[0092] Step S1122: Based on the travel distance, tension, and negative pressure, estimate the estimated replacement time for the target equipment to remove the flap 2 to be replaced from the target suction pipe 1.
[0093] Step S1123: Based on the estimated replacement time and the coke oven coke discharge interval, determine whether the estimated replacement time of the flip plate 2 to be replaced and the target new flip plate 7 is less than the coke oven coke discharge interval where the coke oven dust collector is located.
[0094] Regarding step S1121, the target device can be selected according to the actual situation, and can be in... Figure 2 The multi-interface 6 shown can be equipped with tools such as fixed pulleys as target devices, or vehicles or robots carrying robotic arms can be used as target devices.
[0095] The target device can pull the flip plate 2 to be replaced in any direction, and the travel distance is related to the pulling direction. Specifically, the travel distance can be determined based on the pulling direction selected during implementation. For example, when the pulling direction is diagonally upward, such as... Figure 4 As shown, Figure 4 The shaded area refers to the position of the flap 2 to be replaced before it is pulled out, and the dotted box refers to the position of the flap 2 to be replaced after it is pulled out. The two together form the travel distance L.
[0096] Pull force refers to the pull force generated by the target equipment pulling the flap 2 to be replaced. Specifically, it can refer to the maximum value, intermediate value, etc. in the range of pull force that the target equipment can provide.
[0097] Negative pressure refers to the suction force generated by the coke oven dust collector through the target suction pipe 1 on the flap 2 to be replaced. Specific details can be found in the pressure transmission curve of the coke oven dust collector. Figure 5 The diagram shows a pressure transmission curve, with time on the horizontal axis and pressure on the vertical axis. This means that the pressure of the coke oven dust collector may differ at different times; the corresponding negative pressure at different times can be determined by consulting the pressure transmission curve.
[0098] Regarding step S1122, the difference between the pulling force and the negative pressure is the resultant force that causes the flap to be replaced 2 to move due to the target equipment. Based on the resultant force and the travel distance, the time it takes for the target equipment to remove the flap to be replaced 2 from the target suction pipe 1 can be estimated, that is, the estimated replacement time.
[0099] Regarding step S1123, the coke oven coking interval is usually fixed and can be determined based on factors such as the model of the coke oven dust collector. During the coke oven coking interval, there is essentially no flue gas in the target suction pipe 1. Comparing the coke oven coking interval with the estimated replacement time, if the estimated replacement time is longer than the coke oven coking interval, it means that the flip-plate replacement cannot be completed within the coke oven coking interval.
[0100] When steps S112 and S111 are executed sequentially, if it is determined that the flip plate cannot be replaced within the coke oven discharge interval, step S111 can be skipped, and a prompt message indicating that the flip plate cannot be replaced online can be output directly. This can save computing resources and shorten waiting time, so that operators can perform manual flip plate replacement as soon as possible.
[0101] If the estimated replacement time is less than the coke oven coking interval, it means that the flip-plate replacement can be completed within the coke oven coking interval.
[0102] Regarding step S113, when the flap 2 to be replaced can be maintained on the target suction pipe 1 by friction and the estimated replacement time is less than the coke oven coke discharge interval, that is, when both conditions are met, it means that the flap can be replaced online, and a replacement request is generated.
[0103] Returning to step S11, in response to the replacement request of the flap 2 to be replaced in the target suction pipe 1 of the coke oven dust collector, the actual pressure in the target suction pipe 1 is monitored. This can be done by obtaining the actual displayed pressure of the target suction pipe 1 (the value displayed by the pressure gauge corresponding to the coke oven dust collector system), and then determining the actual pressure in the target suction pipe 1 based on the actual displayed pressure and atmospheric pressure. The actual pressure in the target suction pipe 1 needs to be monitored in real time. The monitoring frequency can be once per second or other monitoring frequencies, which can be set according to the actual situation.
[0104] Regarding step S12, when the actual pressure exceeds the first target pressure, the connecting component 4 used to connect the flap to be replaced 2 and the crank arm 3 is removed, so that the flap to be replaced 2 is maintained on the target intake pipe 1 by friction.
[0105] The first target pressure refers to the pressure corresponding to the operating speed of the coke oven dust collector exceeding the first preset speed. When the actual pressure is detected to exceed the first target pressure, it means that the negative pressure of the target suction pipe 1 on the flap 2 to be replaced is relatively large, and the flap 2 to be replaced can be maintained more stably on the target suction pipe 1. At this time, the connecting part 4 used to connect the flap 2 to be replaced and the crank arm 3 can be removed, so that the crank arm 3 and the flap 2 to be replaced are loosened, and the flap 2 to be replaced can be maintained on the target suction pipe 1 by friction.
[0106] Regarding step S13, control the crank arm 3 to lift up, and install the target new flip plate 7 on the crank arm 3.
[0107] By controlling the push plate 5, the crank arm 3 is raised upward, and after being raised, the target new flip plate 7 is installed on the crank arm 3.
[0108] like Figure 6As shown, before the crank arm 3 is lifted upwards, the replacement flap 2 is pressed tightly against the target air intake pipe 1. After the control push plate 5 lifts the crank arm 3 upwards, the target new flap 7 can be installed on the crank arm 3.
[0109] Regarding step S14, after the flap to be replaced 2 is separated from the crank arm 3, when the actual pressure is less than the second target pressure, the flap to be replaced 2 is separated from the target suction pipe 1, and the crank arm 3 is controlled to carry the new target flap 7 down, so that the new target flap 7 is sealed on the target suction pipe 1; the second target pressure is less than or equal to the first target pressure.
[0110] The second target pressure refers to the pressure corresponding to the operating speed of the coke oven dust collector being lower than the second preset speed; the second preset speed is less than or equal to the first preset speed.
[0111] After executing step S13, that is, after the replacement flap 2 is separated from the crank arm 3, the actual pressure in the target suction pipe 1 is monitored. When the actual pressure is less than the second target pressure, it means that the coke oven dust collector is operating in the low speed range, the negative pressure in the target suction pipe 1 is small, and there is little or no flue gas. Then the replacement flap 2 can be separated from the target suction pipe 1, and at the same time, the crank arm 3 is controlled to carry the new target flap 7 down, so that the new target flap 7 is sealed on the target suction pipe 1, thereby completing the flap replacement process.
[0112] Separating the flap to be replaced 2 from the target suction pipe 1 can be achieved by using the target device to pull the flap to be replaced 2 horizontally, thus separating it from the target suction pipe 1. Alternatively, the target device can be used to pull the flap to be replaced 2 along its normal direction, thus separating it from the target suction pipe 1. Pulling it horizontally reduces the impact of the flap to be replaced 2 on the target new flap 7, while pulling it along its normal direction allows for the use of less pulling force to remove the flap to be replaced 2. The specific method can be chosen based on the actual situation.
[0113] In summary, this embodiment first determines the state between the flap to be replaced 2 and the target air intake pipe 1 to determine whether the flap can be replaced online. When the flap can be replaced online, a replacement request is generated. The actual pressure in the target air intake pipe 1 is monitored. When the actual pressure exceeds the first target pressure, the connecting component 4 used to connect the flap to be replaced 2 and the crank arm 3 is removed, so that the flap to be replaced 2 is maintained on the target air intake pipe 1 by friction. Then, the crank arm 3 is controlled to lift, and the new target flap 7 is installed on the crank arm 3. When the actual pressure is less than the second target pressure, the flap to be replaced 2 is separated from the target air intake pipe 1, and the crank arm 3 is controlled to lower the new target flap 7, so that the new target flap 7 is sealed on the target air intake pipe 1. As can be seen, this embodiment utilizes the suction force of the target suction pipe 1 on the flip plate 2 to achieve the reverse installation steps of "first fixing the target new flip plate 7, then removing the flip plate 2 to be replaced, and finally installing the target new flip plate 7 onto the target suction pipe 1". This can safely, quickly and online realize the replacement of the flip plate 2 on the dust collector, thereby reducing the downtime of equipment such as coke ovens and improving production efficiency.

[0130] Based on the estimated replacement time and the coke oven coke discharge interval, determine whether the estimated replacement time of the flap 2 to be replaced and the target new flap 7 is less than the coke oven coke discharge interval where the coke oven dust collector is located.
[0131] Furthermore, module 74 is replaced for:
[0132] Using the target device, the flap 2 to be replaced is pulled away horizontally, separating it from the target suction pipe 1; or,
