Description

Technical Field

[0001] This utility model relates to the field of coke oven technology, specifically to a furnace body sealing structure based on reducing heat loss in coke ovens. Background Technology

[0002] Due to the high temperature and temperature difference between the furnace body and the environment, heat is lost to the outside through thermal radiation, thermal convection and thermal conduction. For example, the outer surface temperature of the resist wall can reach more than 150°C, and heat is conducted to the outer wall through the 2-meter-thick masonry. Large areas such as the furnace top and riser pipes have significant heat loss due to convection and radiation caused by the high temperature environment. The ambient temperature in some areas may exceed 60°C. The heat loss from the furnace body surface accounts for about 10% of the total heat output of the coke oven, and the loss is about 10.8 kgce per ton of coke, which indirectly increases the cost of fuel procurement and environmental treatment.

[0003] A search revealed that patent CN217781058U discloses a lower insulation structure for a heat recovery coke oven. This structure enhances the oven's sealing by incorporating multiple insulation and sealing layers, reducing heat loss and improving insulation performance. A support layer is also included for stable support, enhancing the structure's stability and safety.

[0004] The aforementioned patent describes an improvement in the insulation and sealing performance of a coke oven by setting multiple insulation and sealing layers. However, while this device can enhance the insulation and sealing performance of the coke oven, damage to any area of ​​the device can affect its overall insulation performance due to the inconvenience of maintenance or replacement. Therefore, we provide a furnace body sealing structure based on reducing heat loss in the coke oven to solve the above problems. Utility Model Content

[0030] The outer surface of the locking block 29 is slidably connected to a movable insulation plate 27. There are two locking blocks 29, and the two locking blocks 29 are in opposite directions.

[0032] In this embodiment, a slope is fixedly connected to the side of the insulation board 22, and a groove is provided on the side of the movable insulation board 27 to fit the slope of the side of the insulation board 22. The slope of the side of the insulation board 22 is pressed down by the squeezing action of multiple movable insulation boards 27 to ensure the stability of the insulation board 22.

[0033] The bottom fixing ring 21 is fixedly connected to the bottom of the outer surface of the furnace body 1, and the top fixing ring 25 is fixedly connected to the top of the outer surface of the furnace body 1, serving as the installation base for the insulation structure of the furnace body 1. After the bottom fixing ring 21 and the top fixing ring 25 are installed, the insulation board 1 22 and the insulation board 23 are first installed on the surface of the feeding port of the furnace body 1, ensuring that the insulation board 1 22 and the insulation board 23 fit together, and the insulation board 1 22 and the insulation board 23 are locked by the fixing locking sleeve 24 to ensure that they have the effect of insulation for the feeding port of the furnace body 1.

[0034] After the insulation board 1 22 and insulation board 23 are installed, prepare the movable insulation board 27, press the two pressing plates 28 to retract the two locking blocks 29 into the interior of the movable insulation board 27, and arrange the movable insulation board 27 on the sides of insulation board 1 22 and insulation board 23 in sequence.

[0035] Example 2: Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the furnace top protection mechanism 3 includes a shell 31, the shell 31 is movably connected to the inside of the limiting plate 26, the inside of the shell 31 is fixedly connected to an insulation liner 35, the insulation liner 35 is tightly attached to the top surface of the furnace body 1, the top side of the shell 31 is fixedly connected to a connecting plate 34, the outer surface of the connecting plate 34 is movably connected to a limiting loop 32, and the top surface of the limiting loop 32 is threaded with a fixing bolt 33.

The side of the outer shell 31 is provided with a slot that fits with the limiting plate 26. The side of the heat-insulating inner liner 35 is inclined, so that after the eight outer shells 31 are connected together, there is a certain gap between the heat-insulating inner liners 35.

[0037] Insert the outer shell 31 into the inside of the limiting plate 26, ensuring that the heat-insulating inner liner 35 is tightly attached to the top surface of the furnace body 1. Arrange multiple outer shells 31 in sequence inside the limiting plate 26, ensuring that the eight outer shells 31 completely cover the top surface of the furnace body 1. After the outer shells 31 are installed, lock the connecting plate 34 with the limiting sleeve 32 and lock the limiting sleeve 32 with the fixing bolt 33. The cooperation between the limiting sleeve 32 and the limiting plate 26 ensures that the outer shell 31 is installed securely.

[0038] The working principle of this furnace body sealing structure, which is based on reducing heat loss in coke ovens, will be explained in detail below.

[0039] like Figure 1-5As shown, by fixing the bottom fixing ring 21 to the bottom of the outer surface of the furnace body 1 and fixing the top fixing ring 25 to the top of the outer surface of the furnace body 1, the installation base of the insulation structure of the furnace body 1 is used. After the bottom fixing ring 21 and the top fixing ring 25 are installed, the insulation board 1 22 and the insulation board 23 are first installed on the surface of the feeding port of the furnace body 1, and the insulation board 1 22 and the insulation board 23 are made to fit together. The insulation board 1 22 and the insulation board 23 are locked by the fixing locking sleeve 24 to ensure that they have the effect of insulation of the feeding port of the furnace body 1.

Then release the pressing plates 28, and the locking blocks 29 are locked into the interior of the top fixing ring 25 and the bottom fixing ring 21 by the pop-out of the fixing spring 210. With the cooperation of the movable insulation board 27 and the pressing plates 28, the movable insulation board 27 is locked inside by bolts, which protects the furnace body 1 and reduces the temperature loss of the furnace body 1 through the movable insulation board 27.

[0041] Insert the outer shell 31 into the inside of the limiting plate 26 to ensure that the heat-insulating inner liner 35 is tightly attached to the top surface of the furnace body 1. Arrange multiple outer shells 31 in sequence inside the limiting plate 26 to ensure that the eight outer shells 31 completely cover the top surface of the furnace body 1. After the outer shells 31 are installed, lock the connecting plate 34 with the limiting cable 32 and lock the limiting cable 32 with the fixing bolts 33. The cooperation between the limiting cable 32 and the limiting plate 26 ensures that the outer shell 31 is installed firmly.

[0042] The number of components based on the movable insulation board 27, insulation board one 22, insulation board two 23, and outer shell 31 exceeds the necessary number of components of the device and can be used to replace damaged components in order to maintain the normal operation of the device.

[0043] When the movable insulation plate 27 is damaged, the bolts used to fix the pressing plate 28 can be removed, and the pressing plate 28 can be squeezed to make the locking block 29 retract back into the movable insulation plate 27, making it easy to replace the movable insulation plate 27. When the first insulation plate 22 or the second insulation plate 23 is damaged, the movable insulation plates 27 on the left and right sides should be removed first, and the fixing lock sleeve 24 should be removed and replaced. When the outer shell 31 is damaged, the fixing bolt 33 and the limiting loop 32 should be removed before replacing the outer shell 31.

[0044] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all modifications or improvements made without departing from the spirit and concept of the present invention are within the protection scope of the present invention.
