Description

Technical Field

[0001] The utility model relates to the technical field of coke oven door bricks, in particular to high-strength, earthquake-resistant, corrosion-resistant, large-scale, energy-saving and environmentally friendly coke oven glaze door bricks. Background Art

[0002] A coke oven is a device that converts coal into metallurgical coke through a high-temperature carbonization process. It is mainly composed of a carbonization chamber, a combustion chamber, a furnace top, a ramp, a heat storage chamber, and a small flue. The main function of the coke oven door is to close the carbonization chamber to make it a sealed space for coking. The coke oven door bricks are indispensable refractory materials in the operation of the coke oven. Their excellent properties and advantages enable the coke oven to achieve efficient, stable, and environmentally friendly operation.

[0003] The existing coke oven door adopts the integral casting method. Due to the large volume of the product and the weight of more than 200 kilograms, it is extremely difficult to dry. Generally, it needs to be placed naturally for two months before the firing process can be carried out, which occupies a large amount of production land. In addition, it is very easy to cause the product to crack when the external temperature changes, which will lead to the scrapping of the entire product. Due to the heavy weight of the bricks, the bricks located on the top of the furnace door will form a large tensile load on the steel plate of the furnace door, which is easy to loosen the furnace door bricks and even cause the furnace door steel plate to deform, thereby losing its tightness. Utility Model Content

[0004] The purpose of the utility model is to provide high-strength, earthquake-resistant, corrosion-resistant, large-scale, energy-saving and environmentally friendly coke oven glaze door bricks, so as to solve the problem that the existing coke oven door proposed in the above background technology adopts an integral casting molding method. Due to the large volume of the product and its weight of more than 200 kilograms, it is extremely difficult to dry. Generally, it needs to be naturally placed for two months before the firing process can be carried out, which occupies a large amount of production land, and is very likely to cause the product to crack when the external temperature changes, thereby causing the entire product to be scrapped. Due to the heavy weight of the bricks, the bricks located on the top of the furnace door will form a large tensile load on the steel plate of the furnace door, which is easy to loosen the furnace door bricks and even cause the furnace door steel plate to deform, thereby losing the tightness.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: high-strength, earthquake-resistant, corrosion-resistant, large-scale, energy-saving and environmentally friendly coke oven glaze door bricks, including door bricks 1;

[0006] The interior of door brick one is slidably connected with door brick two, the outer wall of door brick two fits the inner wall of door brick one, the inner wall of door brick one is connected with two circular plates, the inner walls of the two circular plates both fit the outer wall of door brick two, and the interior of door brick two is connected to the interior of any of the circular plates through multiple connecting parts.

[0007] Preferably, a slot is provided inside the second door brick, a connecting rod is connected to the inner wall of the first door brick, the connecting rod is slidably connected inside the slot, a cross plate is connected to the inner wall of the second door brick, the top end of the cross plate is connected to a limiting frame, and the bottom end of the connecting rod is attached to the inner wall of the limiting frame.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The furnace door bricks are assembled by splicing multiple sets of door bricks one and two, which greatly shortens the drying time required for the production of furnace door bricks and makes them easy to replace and repair. The spliced ​​design enables the furnace door bricks to better adapt to temperature changes and reduce the risk of cracking, thereby reducing the product scrap rate. The spliced ​​furnace door bricks can reduce the tensile load on the steel plate, maintain the tightness of the furnace door, reduce heat loss and environmental pollution. When the spliced ​​furnace door bricks are damaged or need to be repaired, only some bricks need to be replaced, without the need to replace the entire brick, thereby reducing maintenance costs;

[0014] 2. After door brick 1 and door brick 2 are assembled, there is a space between door brick 1 and door brick 2 that can be used as heat insulation, which further reduces the heat conduction efficiency. When the temperature in the furnace is high, the air inside the door brick expands due to the heat and may be discharged through the tiny gaps in the door brick, taking away some heat, lowering the temperature of the door brick, and reducing the thermal deformation or damage of the furnace door brick as a whole caused by high temperature. At the same time, it also helps to maintain the tightness of the furnace door. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 The utility model provides a technical solution: a high-strength, earthquake-resistant, corrosion-resistant, large-scale, energy-saving and environmentally friendly coke oven glaze door brick, including a door brick 1;

[0023] The interior of door brick 1 is slidably connected with door brick 2 3, and the outer wall of door brick 2 3 fits the inner wall of door brick 1. Two round-shaped plates 303 are connected to the inner wall of door brick 1, and the inner walls of the two round-shaped plates 303 fit the outer walls of door brick 2 3. The interior of door brick 2 3 is connected to the interior of any round-shaped plate 303 through multiple connectors 306; by pushing door brick 2 3 into door brick 1, the outer wall of door brick 2 3 fits the bottom end of the round-shaped plate 303 at the lower end of the inner wall of door brick 1, so that door brick 1 and door brick 2 3 can be quickly connected, and door brick 1 and door brick 2 3 are connected through connectors 306, thereby completing door brick 1. The furnace door bricks are assembled by splicing multiple groups of door bricks 1 and door bricks 2 3, which greatly shortens the drying time required for the production of furnace door bricks and makes them easy to replace and repair. The splicing design enables the furnace door bricks to better adapt to temperature changes, reduce the risk of cracking, and thus reduce the product scrap rate. The spliced ​​furnace door bricks can reduce the tensile load on the steel plate, maintain the tightness of the furnace door, reduce heat loss and environmental pollution. When the spliced ​​furnace door bricks are damaged or need repair, only some bricks need to be replaced without replacing the entire bricks, thereby reducing maintenance costs.

[0024] A slot 301 is provided inside the door brick 23, a connecting rod 302 is connected to the inner wall of the door brick 1, the connecting rod 302 is slidably connected inside the slot 301, a cross plate 304 is connected to the inner wall of the door brick 23, the top of the cross plate 304 is connected to the limit frame 1 305, and the bottom end of the connecting rod 302 is attached to the inner wall of the limit frame 1 305; when the door brick 23 enters the door brick 1, the connecting rod 302 slides inside the slot 301 until it enters the limit frame 1 305, so that the bottom end of the connecting rod 302 is attached to the surface of the cross plate 304, thereby enhancing the structural strength between the door brick 1 and the door brick 23.

[0025] The outer wall of the door brick 1 is hung with a glaze layer 2, and the thickness of the glaze layer 2 is 1-3mm; the use temperature is greater than 1100℃, so that the surface of the door brick 1 is smooth and has high hardness, and is not easy to be tarred, which improves the operating environment, prolongs the service life of the door brick 1, and reduces the corrosion of the door brick 1.

[0026] The left and right sides of the outer wall of the glaze layer 2 are both provided with friction layers 201, which can enhance the friction between the door bricks 1 and the door bricks 1 when assembling the door bricks 1, thereby improving the sealing effect.

[0027] An insulating layer is formed between the inside of door brick 1 and the outside of door brick 2 3. When door brick 1 and door brick 2 3 are assembled, there is a space between door brick 1 and door brick 2 3 that can be used for thermal insulation, further reducing the heat conduction efficiency. When the temperature in the furnace is high, the air inside the door brick expands due to the heat and may be discharged through the tiny gaps in the door bricks, taking away some heat, reducing the temperature of the door bricks, and reducing the thermal deformation or damage of the furnace door bricks as a whole due to high temperature, while also helping to maintain the tightness of the furnace door.
