Technical Field

The invention relates to the field of coke production equipment, in particular to high-efficiency centering equipment of a dry quenching hoister.

Background

At present, in the metallurgical industry, particularly in iron works, the coke demand is very high, so each iron work has its own coke production equipment, and in order to protect the environment, the production process of the coke at present basically adopts a dry quenching method, namely, after the coke is heated to a certain temperature, the high-temperature coke is poured into a dry quenching furnace through special equipment, and the coke is cooled by adding inert gas, so that a plurality of byproducts such as coal gas and waste heat which have high economic values are produced in the process, the coal gas is the main fuel for steel making, and the waste heat is used for generating electricity. A dry quenching hoister is a key production device in transfer equipment of high-temperature coke. In order to improve the production efficiency and yield, the dry quenching furnace is usually very high, the height is usually more than 40 meters, in order to transport more coke, the carrier is also designed to be very large, 40-50 tons of coke can be transported each time, so that the carrier filled with high-temperature coke is lifted to the height of 40 meters by a dry quenching hoister, then the carrier is translated to the position right above the dry quenching furnace, the high-temperature coke is filled into the dry quenching furnace through a charging port of the dry quenching furnace, then the charging port is closed, inactive gas is filled in the carrier for cooling, and no water is involved in the whole process, so that the dry quenching method is called. During the operation of the dry quenching hoister, the position of each process environment of the dry quenching hoister needs to be ensured to be accurate, otherwise, a safety accident can happen, if the safety accident happens to 40 tons of high-temperature coke, the caused harm is quite serious, and the harm is next to that of a ladle transferring molten metal. Therefore, in order to ensure the position accuracy of each process link, a plurality of positioning measures are generally required to be simultaneously applied and checked with each other, so that the positioning accuracy and reliability are ensured. In all the positioning measures, the positioning device for translating the coke to the charging port above the dry quenching furnace is particularly critical, and because the wrong positioning can cause the high-temperature coke to be unloaded at the wrong position, serious safety accidents can be caused.

At present, four magnetic limits are generally adopted for positioning the translation position in the coke dry quenching elevator as centering limits, one magnetic limit is taken as a coke oven judging limit, and an absolute value encoder is additionally arranged to be used for detecting the position of the translation mechanism, so that the accurate and reliable positioning of the translation mechanism of the coke dry quenching elevator is ensured by the triple means. In the triple positioning device, the positioning accuracy of the absolute value encoder is +/-500 mm, the coke oven determination limiting accuracy is +/-100 mm, and the centering limiting accuracy is +/-30 mm, so the limiting requirement on centering is extremely high. Similar to a metallurgical crane, the coke dry quenching hoister emphasizes reliability rather than performing the positioning equipment firstly, so in the triple positioning equipment, although the encoder can achieve the accuracy of +/-30 mm, the encoder is a precise electronic product, has relatively poor stability in a severe environment, cannot meet the requirement of high reliability of the hoister, cannot be used as a final positioning means, and has the lowest accuracy requirement. The coke oven determination limit only assists in determining the number of the coke oven, and after the centering action is finished, the coke oven determination limit is ensured to act simultaneously, and the coke oven determination limit can not be used as a final positioning means, so that the requirement can be met when the precision is +/-100 mm. And the centering limit is a final positioning means, the accuracy requirement is the highest, and the limit action is required to ensure that the discharge opening of the carrier is completely aligned with the charging opening of the dry quenching furnace.

The existing centering limit is realized by four magnetic limits which are respectively arranged at two sides of a translation mechanism of the elevator, and two magnetic limits are arranged at each side. And a magnet induction plate integrally processed is arranged at each dry quenching furnace position on the rail bearing beam to enable the magnetic limit to act. It is spacing to correspond the magnetism of lifting machine translation mechanism both sides, respectively install a magnet tablet in every side, make the lifting machine when moving the charge door top of dry quenching stove, the magnet tablet just makes four spacing actions of taking place simultaneously of magnetism, and the requirement, when the spacing action of taking place of magnetism, the spacing edge that just distributes at the magnet tablet of magnetism, the error can not exceed 10 millimeters, otherwise will cause the lifting machine can surpass positioning error in two-way location, when the forward location is accurate promptly, and reverse location will surpass error range.

Four magnetic stops as centering stops were made more than twenty years ago, and were still foreign. The coke dry quenching lifting machine has the advantages of stability and reliability, but the prior art is lagged behind, the installation and maintenance are difficult, the requirements on the installation and adjustment of the positioning limit are very high, especially under the condition of realizing bidirectional positioning, the adjustment becomes very difficult, each coke dry quenching lifting machine usually has 2-4 positioning positions to be adjusted, which means that each lifting machine has 4-8 magnets and at least 8 limits to be adjusted, a large amount of debugging energy is consumed, the difficulty is higher when a plurality of lifting machines operate in a cooperation mode, the adjustment of the centering limit can consume two to three weeks of time, and the efficiency is very low. In the production process of the equipment, errors are usually produced due to various reasons, the positions of the positioning limit positions are changed, the limit positions are required to be re-adjusted, experience and time are required, and generally, when the production process of the equipment fails, maintenance and repair personnel do not have more time to adjust the equipment. This positioning also causes significant disruption to subsequent maintenance and repair.

Therefore, the adjustment efficiency of centering limit of the coke dry quenching hoister is improved only on the premise of ensuring the precision, the maintenance and repair efficiency of the centering limit of the coke dry quenching hoister in the production process is improved, the difficulty of mounting and adjusting the centering limit is reduced, the production efficiency can be improved, and the stable production is effectively ensured.
