[0023] The following is combined with Figure 1-2 This invention describes a specific embodiment of a refining furnace door protection structure, comprising:

[0024] Furnace door mounting plate 1, on which a limiting groove 11 is provided;

[0025] A furnace door sleeve 2 is fixedly connected to the furnace door mounting plate at both ends. A refining furnace charging port 25 is formed on the furnace door sleeve 2. The refining furnace charging port 25 is used to add sintering materials into the furnace body. A circulating fluid pipe 22 is provided inside the furnace door sleeve 2. The circulating fluid pipe 22 is distributed around the inside of the furnace door sleeve 2. The furnace door sleeve 2 is a metal furnace door sleeve 2. The metal door sleeve can be an iron or aluminum alloy door sleeve. The furnace door sleeve 2 replaces the original brick-type furnace door sleeve 2 to strengthen the overall strength of the furnace door sleeve 2 and prevent bricks from falling into the furnace body and affecting the sintering quality. At the same time, the circulating fluid pipe 22 is formed inside the furnace door sleeve 2. The circulating fluid pipe 22 carries cooling fluid to cool the furnace door sleeve 2, realize the over-temperature protection of the furnace door sleeve 2, and thus improve the service life of the furnace door sleeve 2.

[0026] Water tank 3 is fixedly connected to the furnace door mounting plate. A water storage chamber 31 is formed inside the water tank 3, which is connected to the circulating fluid pipe 22. The water tank 3 provides cooling fluid to the furnace door sleeve 2. Simultaneously, the fluid in the water tank 3 is used to displace the temperature of the furnace door sleeve 2, and the high-temperature fluid in the water tank 3 can be used to clean the boiler, thus utilizing the displacement temperature. A float 34 is installed inside the water tank 3, and a temperature sensor 35 is connected to the bottom of the float 34. A viewing plate 33 is provided on the water tank 3 to observe the height of the float 34 within the water storage chamber 31. The float 34 can visually display the liquid level in the water tank 3, assisting operators in observing the liquid level and determining whether fluid needs to be added to the water tank 3. The temperature sensor 35 at the bottom of the float 34 is used to detect the temperature of the fluid within the water storage chamber 31.

[0027] Please refer to Figure 1 As shown, a cooling chamber 21 is formed inside the furnace door sleeve 2. The circulating fluid pipe 22 is located inside the cooling chamber 21. A circulating water inlet pipe 23 and a circulating water outlet pipe 24 are symmetrically arranged on the top of the furnace door sleeve 2. One end of the circulating water inlet pipe 23 is connected to the water storage chamber 31, and the other end of the circulating water inlet pipe 23 is connected to one end of the circulating fluid pipe 22. One end of the circulating water outlet pipe 24 is connected to the water storage chamber 31, and the other end of the circulating water outlet pipe 24 is connected to the other end of the circulating fluid pipe 22. The fluid in the water storage chamber 31 flows into the circulating fluid pipe 22 through the circulating water inlet pipe 23. The circulating fluid pipe 22 is distributed around the cooling chamber 21. Cooling fluid circulates in the circulating fluid pipe 22. The fluid carries the temperature inside the cooling chamber 21 and is transported to the water storage chamber 31 through the circulating water outlet pipe 24 to achieve heat exchange, thereby cooling the furnace door sleeve 2 and achieving over-temperature protection for the furnace door sleeve 2.

[0028] Please refer to Figure 2 As shown, a water pump 36 is provided in the water storage chamber 31. The water pump 36 is fixedly connected to the bottom of the water storage chamber 31. The water pump 36 is used for the mutual circulation of fluid between the water storage chamber 31 and the circulating fluid pipe 22. The water pump 36 is used to pump the fluid in the water storage chamber 31 to the circulating water inlet pipe 23, so as to realize the circulation of fluid between the water storage chamber 31 and the circulating fluid pipe 22, and to cool down the temperature through the circulating fluid.

[0029] Please refer to Figure 2As shown, a limiting space 32 is formed inside the water tank 3. The limiting space 32 is interconnected with the water storage cavity 31. The float 34 is located inside the limiting space 32. The viewing panel 33 faces the limiting space 32. The limiting space 32 is formed by two partitions with through holes, thereby connecting the limiting space 32 and the water storage cavity 31. This ensures that the liquid level in the limiting space 32 and the water storage cavity 31 is kept consistent. By setting the limiting space 32, the floating position of the float 34 is restricted. At the same time, with the setting of the viewing panel 33, the height of the float 34 can be observed directly through the viewing panel 33, thereby determining the fluid volume in the water storage cavity 31.

[0030] Please refer to Figures 1-2 As shown, the top of the water tank 3 is provided with a fluid input pipe 37, which is connected to the water storage cavity 31. The fluid input pipe 37 is used to add fluid into the water storage cavity 31.

[0031] Please refer to Figures 1-2 As shown, the bottom of the water tank 3 is provided with a fluid output pipe 38, which is connected to the water storage chamber 31. The fluid output pipe 38 is used to discharge the fluid in the water storage chamber 31. At the same time, when the temperature of the fluid in the water storage chamber 31 is too high, the fluid in the water storage chamber 31 can be discharged through the fluid output pipe 38, and low-temperature fluid can be added to the water storage chamber 31 through the fluid input pipe 37 to control the temperature in the water storage chamber 31.

[0032] Please refer to Figures 1-2 As shown, it also includes a support plate 4, both ends of which are fixedly connected to the furnace door mounting plate 1, and its top is attached to the bottom of the furnace door sleeve 2. The support plate 4 is used for support during material feeding and to assist in material feeding of the furnace body. A reinforcing plate 41 is provided between the support plate 4 and the furnace door mounting plate 1. The reinforcing plate 41 is used to enhance the stability of the fixation between the support plate 4 and the furnace door mounting plate 1.

[0033] Please refer to Figure 1 As shown, a furnace door 5 is provided in the limiting slide groove 11. The furnace door 5 is slidably connected to the limiting slide groove 11. An electric telescopic device 51 is fixedly provided on the furnace door mounting plate 1. The output end of the electric telescopic device 51 is fixedly connected to the top of the furnace door 5. The furnace door 5 is controlled by the electric telescopic device 51. When the furnace body is being fed, the electric telescopic device 51 controls the furnace door 5 to rise, so as to facilitate the addition of materials into the furnace body. When the furnace body is in refining combustion, the furnace door 5 blocks the feeding port 25 of the furnace door sleeve 2, blocking the air flow inside and outside the furnace body, so as to avoid the furnace body from burning too fast.

[0034] Working principle of this utility model:

[0035] The furnace door sleeve 2 is fixedly installed on the furnace door mounting plate 1. The furnace door sleeve 2 is provided with a refining furnace feeding port 25 for adding materials into the furnace body. The furnace door sleeve 2 is a metal structure. The metal structure prevents the furnace door sleeve 2 from colliding with the furnace door sleeve 2 during feeding and causing debris to fall into the furnace body.

[0036] The water storage chamber 31 stores cooling fluid. The cooling fluid is pumped by the water pump 36 and flows sequentially through the circulating water inlet pipe 23, the circulating fluid pipe 22 and the circulating water outlet pipe 24, and finally flows back into the water storage chamber 31. The circulating fluid pipe 22 is distributed around the cooling chamber 21. When the cooling fluid flows through the circulating fluid pipe 22, heat is exchanged between the cooling fluid and the furnace door sleeve 2, which ultimately cools down the furnace door sleeve 2 and provides over-temperature protection for the furnace door sleeve 2.

[0037] The fluid in the water storage chamber 31 is heated by circulating the fluid. The heated fluid can be discharged through the fluid output pipe 38 and can be used for boiler cleaning, thereby improving the utilization of the boiler body temperature.

[0038] In addition, a limiting space 32 is formed inside the water storage cavity 31. A float ball 34 is floating on the liquid surface inside the limiting space 32, and a viewing plate 33 corresponding to the limiting space 32 is provided on the end face of the water tank 3. The height of the float ball 34 can be directly observed through the viewing plate 33 to analyze the liquid level of the fluid stored in the water storage cavity 31. At the same time, a temperature sensor 35 is provided at the bottom of the float ball 34 to detect and sense the temperature of the fluid inside the water storage cavity 31. When the temperature sensor 35 detects that the temperature is too high and cannot meet the heat dissipation of the furnace door sleeve 2, the fluid in the water storage cavity 31 can be discharged through the fluid output pipe 38, and low-temperature fluid can be added to the water tank 3 through the fluid input pipe 37 to reduce the temperature of the fluid in the water storage cavity 31 and ensure the cooling of the water tank 3.
