Description

Technical Field

[0001] The present application relates to the technical field of calcium carbide furnace discharging equipment, and in particular to a method and device for automatically discharging calcium carbide. Background Art

[0002] During the calcium carbide production process, an arc is generated between electrodes in the calcium carbide furnace. This arc generates high temperatures, which melt the charge and react to form calcium carbide. The calcium carbide is then removed from the furnace at regular intervals and placed in a calcium carbide container.

[0003] At present, the process of unloading calcium carbide from a calcium carbide furnace is as follows: the furnace burner is controlled to burn a furnace eye of a preset area at a predetermined position of the calcium carbide furnace body, and the calcium carbide flows through the furnace eye into the pre-placed calcium carbide container to achieve the purpose of unloading.

[0004] From the above content, it can be seen that the existing technology has at least the following problems: the calcium carbide furnace may have the problem of being discharged too quickly or too slowly. If it is discharged too quickly, the reactants in the calcium carbide furnace will not react fully, which will cause semi-finished calcium carbide to flow out of the furnace eye, reducing the quality of calcium carbide; if it is discharged too slowly, excessive calcium carbide will accumulate in the calcium carbide furnace, resulting in reduced efficiency in producing calcium carbide.

[0052] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work also fall within the scope of protection of this application. In addition, it should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0053] Figure 1 This is an implementation environment architecture diagram of a method for automatically discharging calcium carbide from a furnace according to an embodiment of the present application. Figure 1 As shown, the implementation environment architecture includes: an automatic calcium carbide furnace discharge device, a furnace discharge robot, a burn-through device, a first infrared imager, a furnace eye blocking machine, and a distance detection device.

[0054] The automatic calcium carbide discharging device is connected to the discharging robot through wired or wireless connection, the discharging robot is connected to the burn-through device through wired or wireless connection, the discharging robot is connected to the first infrared imager through wired or wireless connection, the discharging robot is connected to the furnace eye plugging machine through wired or wireless connection, and the automatic calcium carbide discharging device is connected to the distance detection device through wired or wireless connection.

[0055] Among them, the automatic calcium carbide discharge device is used to determine the actual discharge time of the first calcium carbide container, and compare the actual discharge time with the expected discharge time. When the comparison result does not meet the requirements, an instruction to adjust the furnace eye area is sent to the discharge robot.

[0056] Optionally, the automatic calcium carbide discharging device can be a controller.

[0057] The unloading robot receives instructions from the calcium carbide automatic unloading device and performs corresponding operations according to the instructions. For example, after receiving the unloading instruction, the unloading robot controls the burn-through device to perform the furnace eye burning operation. For another example, the unloading robot also receives the furnace eye blocking instruction and controls the furnace eye blocking device to perform the furnace eye blocking operation.

[0058] Among them, the first infrared imager is used to collect the furnace eye image in real time and send the furnace eye image to the furnace unloading robot, so that the furnace unloading robot can determine whether the area of the furnace eye is consistent with the furnace eye set value area based on the furnace eye image, and if it is inconsistent, send the furnace eye burning operation to the burn-through device, or send the furnace eye blocking operation to the furnace eye blocking machine.

[0059] Among them, the automatic calcium carbide discharge device is also used to receive the distance sent by the distance detection device, and determine whether the amount of calcium carbide in the calcium carbide container currently in the discharge state meets the requirements based on the distance, and when the requirements are met, send an instruction to no longer discharge calcium carbide to the current calcium carbide container.

[0060] Optionally, the implementation environment may further include a terminal and a server, the automatic calcium carbide discharging device is connected to the terminal via a wired or wireless connection, and the terminal is connected to the server via a wired or wireless connection.

[0061] The terminal's hardware architecture includes a processor, memory, and display device. Its software architecture includes an application client installed on the terminal, such as a calcium carbide furnace client. Once the application client is activated, the terminal displays an application interface, which receives user input and sends it to a server, or displays one or more messages from the server.

[0062] The types of terminals include but are not limited to smart phones, tablet computers, televisions, laptop computers, desktop computers, etc., and are not specifically limited in this embodiment of the present application.

[0063] The server hardware structure includes a processor, memory, etc., which is used to store various data sent by the calcium carbide automatic furnace device. The server is also used to receive data requests sent by the terminal, respond to the data requests, and return the corresponding data to the terminal.

[0064] The server can be a single server, a server cluster consisting of multiple servers, or a cloud computing service center.

[0065] Figure 2 This is a flow chart of a method for automatically removing calcium carbide from a furnace according to an embodiment of the present application. Figure 2 The method shown can be used by Figure 1 The automatic discharge device of calcium carbide is executed, such as Figure 2 As shown, the method includes the following steps:

[0066] Step 201, determining the actual time of the first calcium carbide container being taken out of the furnace.

[0067] When the calcium carbide in the calcium carbide furnace needs to be unloaded into the calcium carbide container, each furnace eye corresponds to a plurality of calcium carbide containers, and the plurality of calcium carbide containers are connected in sequence so that the unloading operation is performed on the plurality of calcium carbide containers in sequence.

[0068] Furthermore, if the current calcium carbide container is filled with calcium carbide, the calcium carbide container moves forward and aligns the next calcium carbide container with the furnace eye to remove the next calcium carbide container.

[0069] The first calcium carbide container is any calcium carbide container in the current calcium carbide furnace discharge process.

[0070] During the process of performing the furnace-out operation on the first calcium carbide container, the time required to fill the first calcium carbide container is determined, and the time is determined as the actual furnace-out time of the first calcium carbide container.

[0071] Step 202: Determine a first difference between the actual out-of-the-box time and the expected out-of-the-box time.

[0072] Among them, the estimated discharge time is a better discharge time. When the calcium carbide is discharged from the calcium carbide furnace according to the estimated discharge time, the speed at which the calcium carbide flows out of the calcium carbide furnace is neither fast nor slow, which ensures the quality of the calcium carbide and the production efficiency of the calcium carbide.

[0073] Furthermore, the estimated furnace discharge time may be a time determined based on experience. For example, the time required for all calcium carbide containers to be discharged from the furnace in a single cycle may be obtained from historical discharge data, and then the average time required for a single discharge may be calculated and used as the estimated furnace discharge time.

[0074] Optionally, the furnace discharge times that ensure both the quality and production efficiency of calcium carbide can be obtained from historical furnace discharge data, and then the average of the furnace discharge times can be calculated and used as the estimated furnace discharge time.

[0075] Step 203, when the first difference is not within the preset range, adjust the area of the calcium carbide furnace eye to use the adjusted furnace eye to unload the second calcium carbide container, the second calcium carbide container is adjacent to the first calcium carbide container and is located behind the first calcium carbide container.

[0076] When the first difference is not within the preset range, it indicates that the deviation between the actual out-of-the-baking time and the estimated out-of-the-baking time is large, the actual out-of-the-baking time is too fast or too slow, and the actual out-of-the-baking time needs to be adjusted.

[0077] Furthermore, the furnace eye area is generally adjusted to adjust the flow rate of calcium carbide out of the furnace, thereby adjusting the out-of-furnace time.

[0078] Furthermore, since the second calcium carbide holder is adjacent to the first calcium carbide holder and is located behind the first calcium carbide holder, when the furnace eye is adjusted, the second calcium carbide holder will use the adjusted furnace eye to unload the furnace.

[0079] Of course, when the second calcium carbide holder is unloaded from the furnace, steps 201 to 203 are also performed to determine whether the furnace eye area needs to be adjusted again after the second calcium carbide holder is unloaded from the furnace.

[0080] From the above content, it can be seen that the automatic calcium carbide discharge method provided in the embodiment of the present application times the discharge time of the first calcium carbide container and compares it with the expected discharge time. When the two are far apart, it is determined that the furnace eye area needs to be adjusted, thereby changing the discharge time of the second calcium carbide container to achieve the purpose of optimizing the discharge time. Compared with the prior art, when the furnace eye is opened, each calcium carbide pot uses the furnace eye to discharge, that is, all calcium carbide containers are discharged through furnace eyes of the same area. The discharge time of each calcium carbide container remains unchanged, and the time for discharging all calcium carbide containers is also fixed. The embodiment of the present application can dynamically adjust the area of the furnace eye and optimize the discharge time of the calcium carbide container, so that the total time required to discharge all calcium carbide containers can be controlled within the preset time, thereby improving the production efficiency of calcium carbide while ensuring the quality of calcium carbide.

[0081] Furthermore, when the first difference is within the preset range, there is no need to adjust the area of the calcium carbide furnace eye, and the current furnace eye can continue to be used to unload the second calcium carbide container, and the above steps 201-203 are repeated to improve the accuracy of the unloading time.

[0082] Optionally, the calcium carbide container may be a calcium carbide pot, or of course other calcium carbide containers, which is not limited in the embodiment of the present application.

[0083] Alternatively, see Figure 3 In step 201, the actual time of the first calcium carbide container being discharged from the furnace is determined, including the following steps 2011 to 2013:

[0084] Step 2011: receiving the furnace eye burn-through completion mark sent by the furnace unloading robot, and taking the time of receiving the furnace eye burn-through completion mark as the furnace unloading start time.

[0085] The furnace unloading robot is used to detect the furnace eye area in real time, and when the furnace eye area is consistent with the furnace eye set value area, it is determined that the furnace eye burn-through is completed and a furnace eye burn-through completion mark is generated.

[0086] Among them, after the furnace eye is burned through, the calcium carbide flows out of the furnace eye and flows into the calcium carbide container. Therefore, the time when the furnace eye is burned through can be used as the start time of furnace discharge.

[0087] Furthermore, the furnace unloading robot is provided with a first infrared imager, which collects furnace eye images in real time.

[0088] The furnace unloading robot determines that the furnace eye burn-through is complete through the following steps 1 to 3:

[0089] Step 1: Receive the furnace eye image sent by the first infrared imager.

[0090] The first infrared imager collects a furnace eye image once at a preset time interval, and sends the collected furnace eye image to the furnace unloading robot, which receives the furnace eye image.

[0091] The preset time length may be determined based on actual conditions, for example, the preset time length may be determined based on the burn-through speed of the burner. When the burn-through speed is fast, the interval time length may be set to a shorter value, for example, 3 seconds; when the burn-through speed is slow, the interval time length may be set to a longer value, for example, 5 seconds.

[0092] Step 2: determining the actual area of the furnace eye based on the furnace eye image.

[0093] Since the furnace eye image may also include image information around the furnace eye, only the furnace eye image information at the location of the furnace eye can be extracted from the furnace eye image. According to the furnace eye image information, the furnace eye image information consistent with the current furnace eye image information is obtained from the previously established correspondence between the furnace eye image information and the furnace eye area, and the furnace eye area corresponding to the obtained furnace eye image information is queried. The queried furnace eye area is the actual area size of the furnace eye.

[0094] Furthermore, the corresponding relationship between the furnace eye image information and the furnace eye area is established in advance by the following method:

[0095] The furnace eye is burned by a burner to measure the area of the furnace eye. The first infrared imager collects the image of the furnace eye at a predetermined height and angle, and establishes a corresponding relationship between the current furnace eye image and the furnace eye area.

[0096] The furnace eye area is changed by the burn-through device, the height and angle of the first infrared imager remain unchanged, the furnace eye image is collected again, and the corresponding relationship between the furnace eye image and the furnace eye area is established again;

[0097] Repeat the above steps to establish the corresponding relationship between multiple groups of furnace eye images and furnace eye areas.

[0098] In addition, when establishing each set of corresponding relationships, the accuracy of the furnace eye area can be improved by measuring the furnace eye area multiple times and calculating the average value.

[0099] Therefore, it should be noted that the furnace eye image in step one also needs to be collected at a predetermined height and angle to improve the accuracy of the furnace eye image consistent with it queried from the corresponding relationship, thereby improving the accuracy of the determined furnace eye area.

[0100] Among them, the furnace-exiting robot can slide back and forth along a predetermined track, and the position of the track can be set according to the position of the furnace eye, so that the first infrared imager, burn-through device and furnace eye blocking machine installed on the furnace-exiting robot can perform corresponding operations on the furnace eye.

[0101] The first infrared imager can be set at a movable position of the furnace-unloading robot, for example, at the arm of the furnace-unloading robot. When the position of the first infrared imager does not meet the requirements, the furnace-unloading robot can adjust the position of the first infrared imager by adjusting the length, height and angle of the arm to make the position of the first infrared imager meet the requirements.

[0102] The above operations are all described based on the example that the height and angle of the first infrared imager can be adjusted. When the height and angle of the first infrared imager are fixed and only the distance between the furnace-outlet robot and the calcium carbide furnace can change, the correspondence between different distances and image ratios is established in advance by the following method, where the image ratio is the ratio between the actual furnace eye area and the image furnace eye area.

[0103] The unloading robot is moved so that the distance between the unloading robot and the calcium carbide furnace is a first preset distance; the furnace eye is burned by a burner, and the actual area of the furnace eye is measured to obtain the actual area of the furnace eye; the furnace eye image is captured by a first infrared imager, and the area of the furnace eye in the furnace eye image is obtained to obtain the area of the furnace eye image; the ratio of the actual area of the furnace eye to the area of the furnace eye image is calculated to obtain a first ratio; and a corresponding relationship between the first preset distance and the first ratio is established;

[0104] Move the unloading robot so that the distance between the unloading robot and the calcium carbide furnace is a second preset distance; repeat the above steps to obtain a corresponding relationship between the second preset distance and the second ratio;

[0105] According to the above method, a plurality of sets of corresponding relationships between preset distances and ratios are established.

[0106] In actual operation, the actual area of the furnace eye is determined by the following method:

[0107] Collecting a furnace eye image through a first infrared imager and obtaining the area size of the furnace eye image;

[0108] Measure the actual distance between the unloading robot and the calcium carbide furnace, and search for a distance value consistent with the actual distance value in the correspondence between the above different distances and image ratios;

[0109] Get the image ratio corresponding to the queried distance value;

[0110] The product of the furnace eye image area and the image ratio is calculated to obtain the actual furnace eye area.

[0111] Step 3: Compare the actual area of the furnace eye with the set area of the furnace eye. When the actual area of the furnace eye is consistent with the set area of the furnace eye, it is determined that the furnace eye is burned through.

[0112] The fact that the actual furnace eye area is consistent with the set value furnace eye area can be understood as the difference between the actual furnace eye area and the set value furnace eye area is within a preset range.

[0113] If the difference is not within the preset range and the actual area of the furnace eye is larger than the set area of the furnace eye, the furnace eye blocking operation is performed through the furnace eye blocking machine, and the above steps one to three are repeated until the actual area of the furnace eye is consistent with the set area of the furnace eye.

[0114] If the difference is not within the preset range and the actual area of the furnace eye is smaller than the set area of the furnace eye, the furnace eye will continue to be burned through the burner, and the above steps one to three will be repeated until the actual area of the furnace eye is consistent with the set area of the furnace eye.

[0115] Furthermore, the furnace eye blocking machine can also be provided on a furnace unloading robot, and the furnace eye blocking machine can reduce the size of the furnace eye by the following method:

[0116] The calcium carbide automatic discharge device sends a furnace eye reduction instruction to the discharge robot, and the reduction instruction carries the furnace eye set value area;

[0117] The furnace unloading robot controls the furnace eye blocking machine to perform a furnace eye blocking operation to reduce the area of the furnace eye, and uses a first infrared imager to image the furnace eye in real time to obtain a furnace eye image;

[0118] When the furnace unloading robot determines, based on the furnace eye image, that the adjusted furnace eye area is consistent with the furnace eye set value area, it determines that the adjustment is completed.

[0119] Step 2012: Receive the furnace-out completion mark sent by the distance detection device, and use the time of receiving the furnace-out completion mark as the furnace-out completion time.

[0120] The distance detection device is used to determine the distance between itself and the calcium carbide liquid surface, and when the distance reaches a preset value, it is determined that the furnace discharge is completed and a furnace discharge completion mark is generated.

[0121] Optionally, the distance detection device determines that the calcium carbide container has finished being taken out of the furnace through the following steps 1 and 2:

[0122] Step 1: The distance detection device detects the distance between the calcium carbide liquid level and the distance detection device in real time.

[0123] The distance detection device is fixedly mounted at a preset position, generally above the calcium carbide furnace. This preset position enables the distance detection device to detect the central position inside the calcium carbide container. In this way, when the liquid level in the calcium carbide container begins to rise, the distance detection device can continuously detect the position of the liquid level, thereby measuring the distance between the distance detection device and the liquid level according to the distance measurement principle.

[0124] The distance detection device may be an infrared distance sensor, a sonar, or a second infrared imager.

[0125] For the operation method of distance detection using an infrared distance sensor, sonar, or a second infrared imager, please refer to the relevant technology and will not be described in detail here.

[0126] Step 2: When the distance reaches a preset value, it is determined that the amount of calcium carbide in the calcium carbide container reaches a preset requirement, and the calcium carbide container is finally taken out of the furnace.

[0127] When the amount of calcium carbide in the calcium carbide container increases, the liquid level of the calcium carbide will rise, and the distance between the distance detection device and the liquid level will continue to decrease. When it decreases to a preset value, it is determined that the amount of calcium carbide in the calcium carbide container meets the preset requirements, and the calcium carbide container is taken out of the furnace.

[0128] Step 2013: Obtain a second difference between the start time and the end time of the ejection, and determine the second difference as the actual ejection time.

[0129] Optionally, in step 203, adjusting the area of the furnace eye of the calcium carbide furnace includes: when the first difference is a positive value, determining to enlarge the furnace eye; when the first difference is a negative value, determining to reduce the furnace eye.

[0130] When the first difference is positive, it indicates that the discharge speed is slow and the furnace eye needs to be enlarged to speed up the discharge and reduce the discharge time. When the first difference is negative, it indicates that the discharge speed is fast and the furnace eye needs to be reduced to slow down the discharge and extend the discharge time. This ensures that the discharge time of each calcium carbide container is within a certain range, and thus the overall discharge time is also within a certain range.

[0131] For example, the actual out-of-baking time is 3 minutes, and the expected out-of-baking time is 1.5 minutes. The difference between the actual out-of-baking time and the expected out-of-baking time is 1.5 minutes, which is a positive value, that is, the out-of-baking speed is slow. In this case, the furnace eye needs to be enlarged to speed up the out-of-baking and reduce the out-of-baking time.

[0133] The first determining module 401 is used to determine the actual time when the first calcium carbide container is discharged from the furnace;

[0134] A second determining module 402 is configured to determine a first difference between the actual out-of-the-box time and the expected out-of-the-box time;

[0135] Adjustment module 403 is used to adjust the area of the furnace eye of the calcium carbide furnace when the first difference is not within a preset range, so as to use the adjusted furnace eye to unload the second calcium carbide container, and the second calcium carbide container is adjacent to the first calcium carbide container and is located behind the first calcium carbide container.

[0136] Optionally, the adjustment module 403 is further configured to:

[0137] When the first difference is a positive value, determining to increase the furnace eye;
