Description

Technical Field

[0001] The invention relates to the field of coke production equipment, and in particular to a high-efficiency centering device for a dry coke quenching elevator. Background Art

[0002] At present, the demand for coke is very high in the metallurgical industry, especially in iron and steel plants, so each iron and steel plant has its own coke production equipment. For environmental protection, the current coke production process basically adopts the dry quenching method, that is, after the coke is heated to a certain temperature, the high-temperature coke is poured into the dry quenching furnace through some special equipment, and the coke is cooled by adding inactive gas. In this process, many by-products will be produced, such as coal gas and waste heat, which have high economic value. Coal gas will be the main fuel for steelmaking, and waste heat will be used for power generation. In the transportation equipment of high-temperature coke, the dry quenching coke elevator is a key production equipment. In order to improve production efficiency and output, the dry quenching furnace is usually built very high, usually more than 40 meters high. In order to transport more coke, the carrier is also designed to be very large, and can transport 40 to 50 tons of coke each time. This requires the dry quenching coke elevator to lift the carrier loaded with high-temperature coke to a height of 40 meters, and then move it horizontally to the top of the dry quenching furnace, and load the high-temperature coke into the dry quenching furnace through the feeding port of the dry quenching furnace, and then close the feeding port, fill it with inactive gas, and cool it. There is no water involved in the whole process, so it is called the dry quenching method. During the operation of the dry quenching coke elevator, it is necessary to ensure that the position of each process environment of the dry quenching coke elevator must be accurate, otherwise it will cause a safety accident. If a safety accident occurs with 40 tons of high-temperature coke, the harm caused is quite serious, and its harm is second only to the steel ladle that transfers molten metal. Therefore, in order to ensure the position accuracy of each process link, it is usually necessary to use multiple positioning measures at the same time and check each other to ensure the accuracy and reliability of positioning. Among all the positioning measures, the positioning equipment that moves horizontally to the charging port above the CDQ furnace is particularly critical, because incorrect positioning will cause the high-temperature coke to be unloaded at the wrong position, which will cause serious safety accidents.

[0003] At present, the translation position positioning in the dry coke quenching elevator usually adopts four magnetic limiters as the centering limiter, one magnetic limiter as the coke oven judgment limiter, and an additional absolute encoder as the position detection of the translation mechanism. Such triple means are used to ensure the accurate and reliable positioning of the translation mechanism of the dry coke quenching elevator. In this triple positioning device, the positioning accuracy of the absolute encoder is ±500 mm, the coke oven judgment limit accuracy is ±100 mm, and the centering limit accuracy is ±30 mm, so the centering limit requirement is extremely high. The dry coke quenching elevator is similar to the metallurgical crane. For the positioning equipment, it pays more attention to reliability rather than first. Therefore, in this triple positioning device, although the encoder can achieve an accuracy of ±30 mm, because the encoder is a precision electronic product, the stability in harsh environments is relatively poor, and it cannot meet the high reliability requirements of the elevator, so it will not be used as the final positioning means, so the accuracy requirement of the encoder is also the lowest. The coke oven determination limit is only used to assist in determining the coke oven number. After the centering action is completed, it is sufficient to ensure that the coke oven determination limit is also activated. It cannot be used as the final positioning method, so the accuracy of ±100 mm can meet the requirements. The centering limit is the final positioning method, and the accuracy requirement is the highest. It is required that after the limit action, the unloading port of the carrier is completely aligned with the charging port of the dry quenching furnace.

[0004] The current centering limit is realized by four magnetic limiters, which are installed on both sides of the elevator translation mechanism, with two magnetic limiters installed on each side. An integrally processed magnetic induction plate is installed at each dry quenching furnace position on the rail beam to activate the magnetic limiter. Corresponding to the magnetic limiters on both sides of the elevator translation mechanism, a magnetic induction plate is installed on each side, so that when the elevator runs above the feeding port of the dry quenching furnace, the magnetic induction plate just makes the four magnetic limiters activate at the same time, and it is required that when the magnetic limiter is activated, the magnetic limiter is just distributed on the edge of the magnetic induction plate, and the error cannot exceed 10 mm, otherwise it will cause the elevator to exceed the positioning error in bidirectional positioning, that is, when the forward positioning is accurate, the reverse positioning will exceed the error range.

[0005] The technology of using four magnetic limiters as centering limiters was developed more than 20 years ago, and it was a foreign technology at that time. Its advantages are stability and reliability, but the technology is backward at present, and it is difficult to install and maintain. The requirements for the installation and adjustment of the positioning limiters are very high, especially when two-way positioning is required, the adjustment will become very difficult. Usually, each dry quenching coke elevator has 2 to 4 positioning positions that need to be adjusted, which means that each elevator has 4 to 8 magnets and at least 8 limiters that need to be adjusted, which will consume a lot of debugging energy, and it is more difficult when multiple elevators are running in collaboration. Usually, the adjustment of these centering limiters may take two to three weeks, which is very inefficient. In the production process of the equipment, errors are usually produced due to various reasons, and the position of the positioning limiter will change. Re-adjusting these limits requires both experience and time. Usually, when a failure occurs during the production process of the equipment, there is no more time for maintenance and maintenance personnel to adjust the equipment. Therefore, this positioning method also causes great trouble for subsequent maintenance and repair.

[0006] Therefore, only by improving the adjustment efficiency of the centering limit of the dry quenching coke elevator under the premise of ensuring accuracy, improving the efficiency of maintenance and repair of the centering limit of the dry quenching coke elevator during the production process, and reducing the difficulty of installation and adjustment of the centering limit, can we improve production efficiency and effectively ensure stable production.

[0033] The magnet assembly includes a magnet body 8 and a magnet adjustment bracket 9, the magnet body 8 is installed on the magnet adjustment bracket 9 through a magnet fixing shaft 10 and a magnet adjustment shaft 11, the magnet fixing shaft 10 is fastened to the magnet body 8 through a fastening screw, a magnet adjustment handle 12 is installed on the magnet adjustment shaft 11, the magnet adjustment handle 12 and the magnet adjustment shaft 11 are fastened to the magnet body 8 together, and the adjustment head of the magnet adjustment handle 12 will pass through the magnet rotation adjustment stud 13 on the magnet adjustment bracket 9;

[0034] A magnet slide rail sleeve 14 is arranged below the magnet adjustment bracket 9, and two magnet slide rails 15 are arranged inside the magnet slide rail sleeve 14. Both ends of the magnet slide rail 15 are fixedly connected to the magnet mounting bracket 16 through retaining springs. A magnet translation adjustment slot 17 is arranged on the front side of the magnet mounting bracket 16, and a magnet translation adjustment stud 18 is arranged through the magnet translation adjustment slot 17.

[0035] Working principle:

[0036] The magnetic limit 2 is installed on the limit mounting bracket 1 through the limit fixed shaft 3 and the limit adjustment shaft, wherein the fixed shaft fixes the fixed shaft of the magnetic limit 2 on the limit mounting bracket 1 through a retaining spring, which can ensure that the magnetic limit 2 can rotate around the fixed shaft and the fixed shaft will not move. After the limit adjustment shaft 4 of the magnetic limit 2 passes through the limit mounting bracket 1, the limit adjustment slider is sleeved on the limit adjustment shaft 4, and then the limit adjustment shaft 4 is fixed by the retaining spring. The upper part of the limit adjustment slider 5 carries a limit adjustment stud 6, and the limit adjustment stud 6 passes through the limit adjustment stud mounting hole 7 on the upper part of the limit mounting bracket 1, and then the limit adjustment stud 6 is tightened by a pair of anti-loosening nuts. When the anti-loosening nut is in a loose state, the limit adjustment slider 5 can be moved up and down, and the magnetic limit 2 will rotate around the limit fixed shaft 3, so that the horizontal angle of the magnetic limit 2 can be adjusted. After the adjustment is completed, the anti-loosening nut is tightened to prevent the position of the limit adjustment slider 5 from changing.

[0037] The magnet body 8 is installed on the magnet adjustment bracket 9 through the magnet fixing shaft 10 and the magnet adjustment shaft 11, and the magnet fixing shaft 10 is fastened to the magnet body 8 by the fastening screw. The adjustment handle of the magnet adjustment handle 12 passes through the adjustment hole of the magnet adjustment shaft, and the magnet adjustment handle 12 and the magnet adjustment shaft 11 are fastened to the magnet together by the fastening screw. After being fastened by the fastening screw, the magnet fixing shaft 10 and the magnet adjustment shaft 11 are tightly connected with the magnet and will not slide between the magnets. The adjustment head of the magnet adjustment handle 12 will pass through the magnet rotation adjustment stud 13 on the magnet adjustment bracket 9 and then be fixed by the anti-loosening nut. When the anti-loosening nut is in a loose state, the adjustment head of the magnet adjustment handle can rotate around the magnet adjustment shaft 11, thereby driving the magnet to rotate, so that the horizontal tilt angle of the magnet can be adjusted. After the adjustment is completed, the horizontal tilt angle of the magnet can be prevented from changing by tightening the anti-loosening nut.

[0038] The two magnet rails 15 pass through the magnet rail 15 sleeve 14 under the magnet adjustment bracket 9, and then are fixed on the magnet mounting bracket 16 by a retaining spring. The magnet translation adjustment stud 18 on the magnet adjustment bracket 9 will pass through the magnet translation adjustment slot 17 on the magnet mounting bracket 16, and then be fixed by a lock nut. When the lock nut is in a loose state, by moving the horizontal position of the magnet translation adjustment stud 18 on the magnet adjustment bracket 9, the magnet adjustment bracket 9 can be horizontally moved along the magnet rail 15 together with the magnet, so as to adjust the horizontal position of the magnet. After the adjustment is completed, the horizontal position of the magnet can be prevented from changing by tightening the lock nut.

[0039] The limit assembly can be directly installed on the structure of the traveling mechanism of the dry quenching coke elevator through the limit mounting bracket 1, or it can be installed in other ways by expanding the installation method of the limit assembly through the limit mounting bracket 1 mounting hole set on the limit mounting bracket 1.

[0040] The magnet assembly can be directly mounted on the track beam platform of the CDQ elevator through the magnet mounting bracket 16, or the mounting method of the magnet assembly can be expanded through the magnet mounting bracket 16 mounting hole set on the magnet mounting bracket 16, and installed in other ways.

[0041] The magnetic limiter 2 is a key component of the present invention. To ensure the stability of the limiter, the present invention designs the limiter as an integrally formed structure, realizes the functions of two limits through a limiter structure, and encapsulates all the electronic components of the magnetic limiter 2 through an aluminum alloy integrally formed shell, realizes the protection level of IP68, and all electrical connections are led out through a cable connector in the form of an aviation plug. Since the magnetic limiter 2 of the present invention is designed with components and circuits with the same working principle as the original center limiter, the performance of the original center limiter is consistent with or even improved in terms of working reliability and accuracy. In order to facilitate installation and save installation space, the size design of the magnetic limiter 2 of the present invention is relatively small, which will save a lot of space compared to the original limiter installation form. In order to clearly indicate the state of the limiter, a limiter status indicator light in the form of a ring is designed, which are 1# limiter indicator light and 2# limiter indicator light. In order to clearly understand the horizontal state of the limit, an indicator light of the horizontal state of the limit is set in the middle of the limit. The indicator light adopts an RGB indicator light. The present invention can adjust the limit within the range of ±3.5°, so 7 colors can be displayed to indicate the angle state of the limit, with green indicating the horizontal state, i.e. 0°±0.5°, red indicating -3°±0.5°, orange indicating -2°±0.5°, yellow indicating -1°±0.5°, purple indicating 3°±0.5°, blue indicating 2°±0.5°, and cyan indicating 1°±0.5°. In order to facilitate installation and adjustment, a limit fixing shaft 3 and a limit adjustment shaft 4 are designed. These two shafts are solid shafts and will be molded together with the housing of the limit. The electronic circuit of the magnetic limit 2 is mainly implemented by Hall elements. The induction of the magnetic field by the highly sensitive Hall element is used to determine whether a magnet is triggering. The threshold of the action magnetic field strength of the Hall element is set by the detection circuit to 130% of the minimum value of the magnetic field strength that it can detect, thereby ensuring the reliability of the action. The levelness detection can be realized by electronic gyroscope, which has the characteristics of low cost and high sensitivity and is widely used in the field of electronic products. The limiter is processed as a whole by commissioned processing and customized by professional manufacturers to ensure the stability and reliability of the overall quality of the limiter.

[0042] The limit mounting bracket 1 is inverted L-shaped and is made of 2mm thick steel plate. It can also be made of steel plates or stainless steel plates of other thicknesses if necessary. Four ф6mm mounting holes are set on the top of the bracket, and other installation methods can be expanded when the installation of this bracket is limited. A ф5mm limit adjustment stud mounting hole 7 is also set on the top of the bracket. The limit adjustment stud 6 will pass through the hole to achieve the angle adjustment of the program limit. In order to achieve firm fastening after the adjustment is completed and not loose due to vibration, anti-slip patterns are processed on both sides of the mounting hole, and the double anti-loosening nuts can achieve an anti-loosening effect. Two mounting holes are designed on the long side of the bracket, namely the limit fixing shaft 3 mounting hole and the limit adjustment shaft 4 mounting hole. The limit fixing shaft 3 mounting hole will be used to install the fixed shaft of the magnetic limit 2, and the limit adjustment shaft 4 mounting hole will be used to install the adjustment shaft of the magnetic limit 2. The mounting hole of the position-limiting fixed shaft 3 is circular, with the same diameter as the fixed shaft of the magnetic position-limiting 2. When the fixed shaft of the magnetic position-limiting 2 is installed in the hole, it can be ensured that the fixed shaft of the magnetic position-limiting 2 can rotate in the hole. The mounting hole of the position-limiting adjustment shaft 4 is an oblong, and its two long sides are a section of an arc of two concentric circles with the center of the mounting hole of the position-limiting fixed shaft 3 as the center, and the radius difference is the same as the diameter of the adjustment shaft of the magnetic position-limiting 2. When the adjustment shaft of the magnetic position-limiting 2 is installed in the hole, it can be ensured that the adjustment shaft of the magnetic position-limiting 2 can make a circular motion around the center of the fixed shaft in the hole, thereby realizing the adjustment of the horizontal angle of the magnetic position-limiting 2.

[0043] The limit adjustment slider 5 is used to drive the adjustment shaft of the magnetic limit 2 to adjust the horizontal angle of the magnetic limit 2. The limit adjustment slider 5 is an inverted L-shape, 5mm thick, and is made of cold-rolled steel plate or stainless steel plate. An adjustment stud with a diameter of 4mm and a length of 75mm is processed or tightly installed on its short side. It is processed with an M4 thread and the thread length is 45mm. If conditions permit, it is best to process it as a whole with the slider body to ensure the overall strength and rigidity. If it is made by split processing and then installed on the slider body, it must be ensured that the adjustment stud is tightly combined with the slider body, no sliding occurs in all directions, and a certain strength and rigidity are guaranteed. A circular hole is processed on the long side of the slider, and the diameter is consistent with the diameter of the adjustment shaft of the magnetic limit 2. The slider is installed on the adjustment shaft of the magnetic limit 2 through the hole, so that the horizontal angle of the magnetic limit 2 can be adjusted through the slider.

[0044] The magnet of the present invention is mainly composed of a whole piece of magnet plate. The magnet adopts a custom-made neodymium magnet with a thickness of 10mm, a length of 200mm, and a width of 100mm. A keyed mounting hole for the mounting shaft is processed at one end of the magnet plate at a position 10mm near the edge, which is used to install the fixed shaft and the adjustment shaft. The fixed shaft and the adjustment shaft need to be made of stainless steel, and the use of steel materials will interfere with the magnetic lines of force of the magnet. The fixed shaft is a round shaft with a length of 5mm and a diameter of 10mm. The mounting hole is processed in the center, and a key convex is designed at one end of the magnet plate to ensure that it will not slip after being installed on the magnet plate by fastening screws. The adjustment shaft is a round shaft with a length of 10mm and a diameter of 10mm. The mounting hole is processed in the center, and a key convex is designed at one end of the magnet plate to ensure that it will not slip after being installed on the magnet plate by fastening screws. At the same time, the adjustment shaft also needs to be processed with a 3X5mm square hole for installing the magnet rotation adjustment handle.

[0045] The magnet adjustment bracket 9 is roughly a groove-shaped structure, and a groove is formed by adjusting the bracket side plate 1, the adjusting bracket side plate 2 and the adjusting bracket bottom plate, which is used to install the magnet. The magnet adjustment bracket 9 is made of stainless steel. The use of steel material will affect the magnetic lines of force of the magnet. A magnet fixed shaft mounting hole with a diameter of 10mm is processed at one end of the adjustment bracket side plate 2, and a magnet adjustment shaft 11 mounting hole with a diameter of 10mm is processed at one end of the adjustment bracket side plate 2. The adjustment bracket side plate 2 also needs to process a magnet rotation adjustment stud 13 and a magnet translation adjustment stud 18. The diameter of these two studs is 5mm, and M5 threads are processed on them. Two magnet translation slide guide cylinders are processed at the bottom of the adjustment bracket bottom plate. These two guide cylinders are preferably processed as a whole with the entire adjustment bracket. If they are processed separately, it is difficult to ensure their straightness, which affects the application effect. The magnet adjustment bracket 9 will be installed on the magnet mounting bracket 16 through two stainless steel 10mm diameter circular slide rails passing through these two magnet translation slide guide cylinders, and the translation adjustment effect of the entire magnet is achieved.

[0046] The magnet rotation adjustment handle is made of stainless steel. It is divided into an adjustment handle and an adjustment head. The adjustment handle is 3mm thick and 43mm long. The end is chamfered and a mounting hole with a diameter of 3mm is processed 8mm away from the end face. The adjustment head is an oblong with an oblong hole in the middle. Its two long sides are a section of an arc of two concentric circles with the center of the mounting hole as the center. The radius difference is 5mm. The hole is used to install the magnet rotation adjustment stud 13 to achieve the angle adjustment of the magnet.

[0047] The magnet mounting bracket 16 is made of stainless steel, and the use of steel material will interfere with the magnetic field lines of the magnet. The shape of the entire bracket is roughly a table shape, with the top being a bottom plate, the two ends of the bottom plate being mounting legs, and one side of the bottom plate being an adjustment side plate.

[0048] The mounting legs are L-shaped, and the top of the long side is processed with a slide rail mounting hole for mounting the magnet slide rail 15. The short side is processed with a mounting hole with a diameter of 8mm to expand the mounting form of the magnet mounting bracket 16. The middle part of the adjustment side plate is processed with a translation adjustment stud slide groove for mounting the magnet translation adjustment stud 18. The slide groove is a 6X100 oblong hole for mounting the magnet translation adjustment stud 18 to achieve translation adjustment of the magnet.

[0049] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
