Description

Technical Field

[0001] The invention relates to the technical field of ramming coke ovens, and in particular to a radar-type automatic detection and crushing collection device for coal collapse in ramming coke ovens. Background Art

[0002] The tamping process refers to tamping loose coal into coal cakes for dry distillation. The tamping process can add a certain amount of inferior coal to the coal blending to replace high-quality coal for coking. The use of the tamping process for coking not only makes the utilization of coal resources more reasonable, but also improves the quality of coke under the same coal blending conditions.

[0003] The tamping coal loading car is the core equipment of the whole set of tamping coke oven equipment. Its main function is to deliver the tamped and compacted coal cakes into the carbonization chamber of the furnace body. During the transportation of coal cakes, the tamping coal loading car may collapse. The collapsed coal blocks the forward route of the coal loading bottom plate, making it impossible to load coal. Since the coal cakes of large-scale tamping coke ovens are all above 50t, it is very difficult to clean them. It has become one of the important factors affecting the normal production and automatic operation of coke oven machinery and equipment.

[0004] At present, when coal cake collapse occurs, the existing technology has certain shortcomings. 1. Coal cake collapse is identified manually, and coal collapse cannot be identified automatically; 2. The collapsed coal is in block shape and has a certain strength, which can easily hurt people, and it is difficult for traditional scrapers to collect and transport it. Summary of the invention

[0005] According to the above technical problems that it is difficult to automatically identify the collapsed coal cakes and it is difficult to collect the collapsed coal cakes, a radar-type automatic detection and crushing collection device for ramming coke oven collapsed coal is provided. The present invention mainly develops an automatic detection and crushing collection device, so as to achieve the effect of automatically detecting and collecting collapsed coal.

[0006] The technical means adopted by the present invention are as follows:

[0007] A radar-type automatic detection and crushing collection device for tamping coke oven coal collapse, arranged under the body steel structure of a tamping coal loading vehicle, characterized in that it comprises: a crushing device, a crushed coal collection scraper, a coal transfer scraper and a collection bucket;

[0008] The crushing device is arranged below the coal loading bottom plate between the carbonization chamber of the furnace body and the steel structure of the car body, and is arranged on the front side of the steel structure of the car body;

[0009] The crushed coal material collecting scraper is arranged below the crushing device; the crushed coal material collecting scraper is connected to the coal material transfer scraper and is arranged on the side of the vehicle body steel structure; the coal material transfer scraper is connected to the collection bucket;

[0010] On the side of the vehicle body steel structure above the crushing device, a radar-type automatic detection device is provided, and the radar-type automatic detection device includes a radar-type sensor;

[0011] The automatic detection steps of the automatic detection and crushing collection device are as follows:

[0012] During operation, when the coal material collapses from both sides in the running direction, the coal material falls into the crushing device to form a pile with a certain weight; set the starting pile height value A1 and the limit pile height value A2;

[0013] The radar-type sensor emits radar signals to the pile, judges the pile height through the time difference of the round-trip of the radar wave, obtains the real-time pile height value A3, and uses the starting pile height value A1 and the real-time pile height value A3 to obtain the real-time state information of the falling coal material relative to the vehicle body;

[0014] Transmit the real-time state information to the on-vehicle PLC system, and judge the real-time state information with the predetermined height value to obtain three states: when A2 < A1, there is no need to start the automatic crushing device; when A3 > A2 ≥ A1, send a start signal to the crushing device, the crushed coal material collecting scraper conveyor, and the coal material transfer scraper conveyor; when A2 ≤ A3, an alarm is given and manual handling is required.

[0015] Further, the crushing device includes a plurality of collecting baffles and a plurality of groups of crushing drums. The collecting baffles are used to collect the scattered coal material. Below the collecting baffles, there are crushing drums. Below the crushing drums, there is a discharge port. The discharge port is located above the crushed coal material collecting scraper conveyor. One side of the crushing drum is connected to a driving motor, and the other side of the driving motor is connected to another crushing drum.

[0016] Further, each group of crushing drums is provided with two, and the two crushing drums rotate relatively. The two crushing drums are respectively connected to a driving motor with opposite rotation directions.

[0017] Further, the crushing drum is connected to the driving motor through a coupling.

[0018] Further, the radar-type sensor is arranged facing the crushing device, and a blowing head is arranged on the side of the radar-type sensor. The blowing head is connected to an air compressor.

[0019] Further, the crushed coal material collecting scraper conveyor, the coal material transfer scraper conveyor, and the collecting hopper are fixed on the vehicle body steel structure.

[0020] Further, the crushing and collection steps of the automatic detection and crushing collection device are as follows:

[0021] After the coal cakes are tamped and formed in the tamping box, they are sent to the carbonization chamber by the coal loading bottom plate. When the coal cakes are loaded, the radar type automatic detection device is started to scan and detect;

[0022] After the crushing device, the crushed coal material collecting scraper and the coal material transporting scraper receive the start signal, the crushing device starts, the driving motor drives the crushing drum to rotate through the coupling, and the coal material that falls into the crushing device is collected by the collecting baffle, and after being crushed by the crushing drum, the coal material falls from the discharge port into the crushed coal material collecting scraper;

[0023] The coal falls into the collecting bucket through the coal transfer scraper on the crushed coal collecting scraper, and is transported away by the transport vehicle.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] The present invention provides a radar-type automatic detection device and a specific strategy for automatic identification, so that coal caving during coal loading is automatically identified instead of manually, thereby improving the reliability and safety of coke oven production.

[0026] The present invention provides a crushing device, a crushed coal collection scraper, a coal transfer scraper, and a collection bucket, so that the collapsed large-particle coal falls into the crushing device, and then falls into the scraper after being crushed, which is convenient for transportation and reduces the amount of daily maintenance.

[0027] The invention uses compressed air to purge the radar sensor probe, so as to purge the coal material attached to the probe and increase the working accuracy.

[0028] The invention improves the automation and environmental protection of the coke oven machinery. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0041] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0042] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0043] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0044] like Figure 1-7As shown in the figure, the present invention provides a radar - type automatic detection, crushing and collection device for caving coal in a stamping coke oven, which is applied to a stamping coal charging car to automatically identify and collect the caving coal during the coal charging process. The radar - type automatic detection, crushing and collection device for caving coal in a stamping coke oven is composed of a vehicle body steel structure 1, a crushing device 2, a radar - type automatic detection device 3, a crushed coal material collection scraper conveyor 4, a coal material transfer scraper conveyor 5, and a collection hopper 6. The crushing device 2 is composed of a collection baffle 21, a driving motor 22, a coupling 23, a crushing drum 24, and a discharge port 25; the radar - type automatic detection device 3 is composed of a radar - type sensor 31, a purging head 32, and an air compressor 33. The crushing device 2, the radar - type automatic detection device 3, the crushed coal material collection scraper conveyor 4, the coal material transfer scraper conveyor 5, and the collection hopper 6 are fixed on the vehicle body steel structure 1.

[0045] The coal material 7 is arranged on the coal charging bottom plate of the vehicle body steel structure 1, and the coal charging bottom plate sends the coal material 7 into the furnace body carbonization chamber 8. During the process that the coal charging bottom plate extends out of the vehicle body steel structure 1 to send the coal material 7 into the furnace body carbonization chamber 8, the coal material 7 will fall from both sides of the coal charging bottom plate.

[0046] The crushing device 2 is arranged below the coal charging bottom plate between the furnace body carbonization chamber 8 and the vehicle body steel structure 1.

[0047] The automatic detection process is as follows:

[0048] 1. During the operation, if the coal material 7 caves in, it falls from both sides of the running direction, and the coal material 7 falls into the crushing device 2, and the coal material 7 will form a pile with a certain height. At the initial stage of debugging, a predetermined pile height value A1 and a limit pile height value A2 are set.

[0049] 2. The radar - type sensor 31 fixed on the vehicle body steel structure 1 emits radar signals to the pile, and uses the time difference of the round - trip of the radar wave to judge the pile height, obtaining the pile height value A3. Using the difference A3 between the predetermined pile height value A1 and the detected value, the state information of the caving coal material 7 relative to the vehicle body at this time is obtained.

[0050] 3. Transmit the real - time state information to the on - vehicle PLC system, and judge the detected value and the predetermined height value, obtaining three states: 1. When A2 < A1, there is no need to start the automatic crushing device; 2. When A3 > A2 ≥ A1, automatically start the crushing device 2, the crushed coal material collection scraper conveyor 4, and the coal material transfer scraper conveyor 5; 3. When A2 ≤ A3, an alarm is given and manual handling is required.

[0051] The collection process is as follows:

[0052] 1. After the coal cakes are tamped and formed in the tamping box, they are sent to the carbonization chamber by the coal loading bottom plate. When the coal cakes are loaded, the radar sensor 31 in the radar automatic detection device 3 is started to scan and detect the material pile in the crushing device 2. The radar automatic detection device 3 is fixed on the vehicle body steel structure 1.

[0053] 2. If coal 7 collapses during operation, it will fall from both sides of the running direction and fall into the crushing device 2. The coal 7 will form a pile of a certain height. At this time, the radar sensor 31 in the radar automatic detection device 3 will receive the pile height signal, convert it into a quantity signal, and transmit it to the vehicle-mounted system, automatically starting the crushing device 2, the crushed coal collection scraper 4, and the coal transfer scraper 5.

[0054] 3. The crushing device 2 is started, and the two drive motors 22 rotate in opposite directions, driving the crushing drum 24 to rotate through the coupling 23. Figure 4 The coal material 7 that falls into the crushing device 2 is collected by the collecting baffle 21, and after being crushed by the crushing drum 24, the coal material 7 falls into the scraper from the discharge port 25.

[0055] 4. The coal 7 falls from the discharge port 25 into the crushed coal collecting scraper 4, and then the coal 7 passes through the coal transporting scraper 5 and falls into the collecting bucket 6, and is finally transported away by a transport vehicle.

[0056] 5. Dust exists in the working area, which can easily block the radar sensor 31 probe. Before loading coal each time, start the air compressor 33. The compressed air generated by the air compressor 33 reaches the purge head 32 through the pipeline. The purge head 32 faces the radar sensor 31 probe and blows off the coal 7 attached to the probe. The radar sensor 31 probe is always purged during its operation to increase its working accuracy.

[0057] As the national environmental protection policy becomes increasingly stringent, the coke oven industry has continuously raised the automation level and environmental protection requirements for coke oven machinery. This application is installed on a tamping coal loading car or a tamping coal loading coke pusher (SCP integrated machine). During the coal loading process, the coal material collapse is automatically identified instead of manually, which improves the reliability and safety of coke oven production. The collapsed large-particle coal falls into the crushing device, and after being crushed, it falls into the scraper, which is convenient for transportation and reduces the amount of daily maintenance. The device also improves the automation level of coke oven machinery, which can significantly enhance the market competitiveness and economic benefits of the group company's products.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
