Description of the new type: [Technical field to which the new type belongs] This new type is related to a furnace wall for repairing a furnace door, especially for repairing a furnace wall of a coke oven, and has simple operation and improvement. It is used to repair the furnace door for industrial safety. Door [Prior technology] A coke oven is a huge device that is used to produce coke bores. It is about 6.5 meters high and about 0.6 meters wide. It is used to close the furnace door of the coke oven. Door puller to perform automatic loading and unloading of furnace doors. During coking, large 10 * coal is placed in the coking oven chamber, and after the furnace mouth is closed by the furnace door, the retorting operation is carried out. During the operation, the temperature in the furnace can reach 1600 or even ν. The high temperature of C, after the coke is refined, the furnace door is removed to remove the coke bore, and it is used for the subsequent operation or transported to downstream manufacturers to further manufacture other products. The walls of the coke oven are made of refractory monuments. During coking, these refractory monuments are subjected to extremely high temperatures, but when the furnace door is opened after coking, the hot and cold air is easily convected due to the extreme temperature difference between the inside and outside of the furnace. "It is a furnace wall located near the furnace mouth. In the expansion state in the original high-temperature environment, it was suddenly shrunk by being blown by the cold air from the outside. This situation will seriously affect the structure of the wall. Over time, the furnace wall near the mouth of the furnace will be repeatedly thermally expanded and contracted. And aging, and further cracked and damaged. After the furnace wall is cracked, gas is likely to emerge from the cracked place, so that the fuel is not completely burned during coking. The quality of the produced coke is generated, and fine particles are formed through the chimney connected to the coking furnace chamber. The exhaust gas is discharged to the outside world, causing air pollution to M260554. Therefore, the furnace wall near the furnace mouth often needs to be repaired. At present, the industry uses ceramic welding to repair cracks to ensure the coke produced by the coke oven and reduce the possibility of air pollution. See Figure 1. Generally speaking, there are many coke ovens in the coking plant. Each coke oven 1 is provided with a furnace door 12 for closing its furnace mouth 11 as shown in the middle of FIG. 1, and the surface of the furnace door 12 is provided with two separate hook blocks 13 for one door pull. The machine (not shown) exerts force, so that the furnace door 12 can be loaded and unloaded on the coke oven 1 through the door puller, and then the oven furnace opening 11 is opened and closed. In order to repair the furnace wall 14 in the coke oven 1 as shown in FIG. 2, the door 12 that originally closed the furnace mouth u must be removed by the door puller, as shown in e Hai coke oven on the right side of Η 1 . Referring to FIG. 2, due to the temperature return in the furnace, a worker must stand on a hydraulic lifting platform truck 15 wearing a fireproof clothing, and gradually hang a plurality of heat shields 16 at the furnace mouth to cover the furnace mouth 11 ′. To prevent cold air from entering the furnace chamber of the coke oven i (as shown in the coke oven on the left side of FIG. 1). When the worker wants to repair the crack in the furnace wall 14 of a certain part, he removes the insulation shield 16 corresponding to the furnace wall 14 in this part, and extends the repair tool from the opened furnace mouth u into 7 The furnace wall 14 is repaired by welding. It can be inferred that in the past, the repairing of the furnace wall 14 has the following disadvantages: (1) laborious and time-consuming: The traditional heat shield 16 is mainly composed of heat insulation H fiber cotton, which has a large volume and is very It is heavy, and it is not possible to use the appliance to perform the installation and removal of the heat shield. It can only be manually hung or removed one by one, which is laborious and time consuming. 5 10 15 M260554. (2) Low safety: As the workers need to take an Youqing lifting platform truck 15 to an appropriate height to load and unload multiple heat shields 16 and repair the furnace wall 14 one by one in a high temperature environment, although the workers are performing this Before work, I will do my own protective measures, such as wearing fireproof clothing, etc. However, the overall operation time is still long, so it is necessary to consider the safety of the staff. (3) The furnace wall is easy to be damaged. According to item (1), it is necessary to hang the insulation shield 16 before removing the furnace door 12, but it is very time-consuming to hang the insulation shield 16. Therefore, the insulation shield 16 has not yet been used. The area of the isolated furnace wall 14 is prone to be exposed to the outside for a long time, which makes the furnace wall 14 easy to be cooled and cooled, resulting in volume shrinkage and structural damage. (4) Decrease in overall output: As mentioned above, due to the long time required to repair coke ovens and the inability to smelt coke in this & operation h, the overall due production should be relatively reduced. (5) Waste generation Object: As the heat shield 16 maintains a good heat insulation effect, it takes time, 5 ...,; I 16 Μ Taomman fiber cotton, the removed Taojing fiber cotton can not be used for other purposes and have a field ^ Recycling can only be discarded, increasing waste and causing environmental issues. $ 4 Ware here 'In order to enable the repair work of the furnace wall to be completed in a shorter working time, to ensure the safety of the workers and to save the staff when trimming the coke oven' Force 'to avoid or reduce the damage caused by maintenance 20 M260554 I'd like to exert due productivity, and avoid related environmental protection problems, which is an urgent need to improve the relevant industry. [New content] 5 10 15 Therefore, the purpose of this new model is to provide a way for workers to hang a heat shield without time-consuming labor before repairing a coke oven. Reduce the damage of the furnace wall due to cold shrinkage during maintenance, and reduce the maintenance and repair of the furnace door caused by related environmental problems. Yu Yu, the new type of furnace wall repair furnace door is suitable for closing the furnace door when repairing the coke oven. The coke oven furnace door is equipped with a door. The furnace wall repair door contains a frame _, 吝 童 p Bow Toxie L 2 Huamuxie several door leafs, many heat insulation panels, and a bolt unit. The frame is capable of snapping against the door frame and opening a plurality of through-holes. The fans are connected to the frame and correspond to the poems. The heat insulation plates are attached to a surface of each door near the coke oven to exert heat insulation. The door bolt unit is connected to the frame and can be rotated relative to the frame to be snapped against the door frame. The effect is that the repairing furnace door can use a door puller to load and unload the repairing furnace door by mechanical operation, so that the time for repairing the furnace room can be shortened, the workload of the staff can be reduced, and the workload can be increased. Overall energy, reducing waste generation.
