Description
The present invention relates to a method of preventing air leakage of a sintering machine, and in particular, loads the raw material, forms a packed layer of the raw material, and accurately recognizes the position of each pallet that is circulated endlessly on the sintering machine. By combining the leak detection method, it is a very suitable technique for use for detecting the air leak due to the pallet of the sintering machine.
In the blast furnace steel industry, as shown in FIG. 9, a series of pallets P and a series of pallets, in which a plurality of
By the way, this
Therefore, as a method of detecting air leaks conventionally, various methods can be considered as disclosed in
Patent Literature 3 discloses a method invention for detecting a line great arrival position before sintering combustion. The pallet position recognition method of the sintering machine of patent document 3 is a pallet position recognition method using the pallet sensor which used the micro switch etc .. The pallet sensor is arrange | positioned in the specific position which the pallet of a sintering machine passes through the upper part, and detects the specific site | part, for example, the advance direction shear of each pallet which passes over this pallet sensor. First, the number of the pallet on the pallet sensor is stored, and when the next pallet is detected by the pallet sensor, the pallet number of the pallet numbered list stored in advance is updated and the time at that time is stored. This is repeated and the pallet's moving speed is calculated from the difference in passing time and the length per pallet. Based on this movement speed, a specific pallet position is calculated | required as distance from an ignition, for example.
In addition, Patent Document 4 describes detecting the passage of an object using a REID tag. The technique of patent document 4 detects the passage of an object, but does not detect a position. In addition,
However, in the "Pallet Position Recognition Method of Sintering Machine" described in Patent Literature 3, due to the pallet sensor using a micro switch or the like, if the pallet recognition is missed or double reads for some reason, the position to recognize more than one pallet is not found. As a result, the pallet is repaired, and as a result, a pallet that does not have an air leak is repaired, and the pallet to be repaired is left on-line as it is, resulting in a problem that the air leak is not eliminated.
In practice, a series of pallets of a sintering machine are usually composed of 100 or more pallets, and since they travel around the sintering machine at about 90 minute intervals, the pallet sensor needs to detect the passage of the pallet at least 1600 times a day. There is. Since the sintering machine normally operates continuously for 30 days or more, the number of times of recognition is 50000 times in one month, and there is a problem in the durability of the pallet sensor using a micro switch or the like which repeats the switch on and off by mechanical operation. In addition, since the environment around the sintering machine has a severe harsh environment such as high temperature, high humidity, and high dust, it is not easy to maintain a conventional pallet sensor in a normal state with high sensitivity over a long period of time.
In view of the problems of the above-described conventional pallet position recognition device of the sintering machine, the present invention provides a pallet position recognition device of the sintering machine capable of stably and with high accuracy recognizing the position of the pallet that is circulating endlessly on the sintering machine for a long time. A first object of the present invention is to provide an air leak detecting device of a sintering machine, comprising the pallet position detecting device and capable of detecting the air leak caused by the pallet over a long period of time stably and with high accuracy. It is for the second purpose.
The summary of this invention is as having described below.
Pallet position recognition device of the sintering machine of the present invention is a series of pallets of endless series of pallets in which a plurality of pallets that are loaded with sintered raw materials and moveable are connected to the moving direction, and whose front and rear ends are connected, and fixed to a housing.
