Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of sintering ring cooler, specifically relating to a sealing structure for the fume hood of a sintering ring cooler. Background Technology
[0002] In the sintering process of steel production, the annular cooler is a key piece of equipment for cooling sintered ore. However, there is a gap between the trolley side panel and the fume hood of the annular cooler. If it is not sealed, it will lead to a large amount of air leakage. This will not only reduce the cooling effect and waste energy, but also cause dust to fill the annular cooler area and pollute the environment. At present, the sealing technology of the upper fume hood of the annular cooler in the sintering plant of various steel enterprises mainly relies on rubber seals.
[0003] In existing systems, there is a gap between the trolley sideboard and the fume hood when the refrigeration trolley is running. By filling the gap with rubber sealing rings, hot air leakage and cold air ingress can be effectively prevented. However, rubber sealing materials are prone to aging and hardening in harsh environments with high temperature and high dust, requiring frequent replacement. This not only increases the procurement cost of sealing materials but also significantly increases the workload of maintenance. Utility Model Content
[0004] The purpose of this invention is to provide a sealing structure for the fume hood of a sintering ring cooler to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing structure for a sintering ring cooler fume hood, comprising:
[0006] The ring cooler trolley has a railing, the top of which is equipped with a sealing fume hood. The bottom outer surface of the sealing fume hood is connected to a water tank for sealing via a mounting bracket. The top of the ring cooler trolley railing extends upward into the water tank.
[0007] The scraper is located inside the water tank and its top is connected to the side panel of the annular cooler trolley via a fixing rod.
[0008] Preferably, one side of the annular cooler trolley is provided with an annular cooler frame column, and the water tank side is connected to the annular cooler frame column through a fixed bracket.
[0009] Preferably, a water supply pipe is provided on one side of the water tank.
[0010] Preferably, the bottom of the water tank is provided with a sewage pipe.
[0011] Preferably, both the water supply pipe and the sewage discharge pipe are equipped with electric valves.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] (1) By adding a water tank between the sealing fume hood and the side panel of the ring cooler trolley, and by immersing the extended part of the side panel of the ring cooler trolley into the water tank to form a water seal structure, the air leakage rate of the ring cooler is greatly reduced. Furthermore, the water seal can effectively block the leakage of hot air and dust, which not only improves the thermal efficiency of the cooling system and ensures a more uniform cooling effect for sintered ore, but also avoids the problem of needing to frequently replace the sealing material.
[0014] (2) Add a water supply pipe to the outside of the water tank and use an electric valve to control automatic water supply. The automatic water supply mechanism can ensure the continuous and stable operation of the sealing device, reduce manual intervention, and improve the continuity and stability of production.
[0015] (3) Add an ash hopper and a sewage pipe to the bottom of the water tank and use an electric valve to control the automatic sewage discharge, maintain the cleanliness of the water in the water tank, and thus ensure that the water sealing effect is not affected and extend the service life of the sealing device.

[0017] In the diagram: 1. Side rails of the annular cooler trolley; 2. Sealed fume hood; 3. Water tank; 4. Scraper; 5. Mounting frame; 6. Frame column of the annular cooler; 7. Fixed bracket; 8. Water supply pipe; 9. Sewage discharge pipe; 10. Electric valve. Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] This utility model provides, for example Figure 1 The sintering ring cooler fume hood sealing structure shown includes:
[0020] The ring cooler trolley railing 1 has a sealing fume hood 2 on its top. The bottom outer surface of the sealing fume hood 2 is connected to a water tank 3 for sealing via a mounting bracket 5. The top of the ring cooler trolley railing 1 extends upward into the water tank 3.
[0021] Scraper 4, the scraper 4 is disposed in the water tank 3 and the top of the scraper 4 is connected to the side panel 1 of the annular cooler trolley by a fixing rod.
[0022] The annular cooler trolley railing 1 has an annular cooler frame column 6 on one side, and the water tank 3 is connected to the annular cooler frame column 6 on one side through a fixed bracket 7.
[0023] A water supply pipe 8 is provided on one side of the water tank 3 for supplying water to the water tank 3.
[0024] The bottom of the water tank 3 is equipped with a sewage pipe 9, which is used to discharge the impurities accumulated in the water tank 3.
[0025] Both the water supply pipe 8 and the sewage discharge pipe 9 are equipped with electric valves 10, which can control the opening and closing of the water supply pipe 8 and the sewage discharge pipe 9.
[0026] The sealing structure of the sintering ring cooler fume hood adds a water tank 3 to the existing sealing fume hood 2 and the ring cooler trolley side panel 1. The water tank 3 is fixed to the sealing fume hood 2 and connected by a fixing rod. The sealing fume hood 2 and the trolley side panel have no direct contact, avoiding wear problems. Since the ring cooler trolley side panel 1 extends outward into the water tank 3, a water seal is formed. When the water tank 3 is filled with water, the extended part of the ring cooler trolley side panel 1 and the bottom of the sealing fume hood 2 are simultaneously immersed in water. The water's barrier and sealing effect fills the gap between the sealing fume hood 2 and the ring cooler trolley side panel 1, preventing hot air, dust, etc. from leaking out of the ring cooler.
[0027] A water supply pipe 8 is added to the outside of the water tank 3, and an electric valve 10 is used to control automatic water replenishment. During the operation of the annular cooler, the water level in the water tank 3 will gradually drop due to water evaporation, splashing, etc. When the water level drops to a certain level, the liquid level sensor (not shown in the attached figure) in the water tank 3 can capture the liquid level change. Once the water level drops to the preset lower limit value, the liquid level sensor will immediately convert this information into an electrical signal and transmit it to the connected control system. The control system controls the electric valve 10 on the water supply pipe 8 to open. At this time, water can be replenished into the water tank 3 through the water supply pipe 8 to ensure that the water tank 3 always maintains a sufficient water level and maintains a good water seal effect. As water continues to flow into the water tank 3, the liquid level gradually rises. The liquid level sensor continuously monitors the liquid level change. When the water level rises to the preset upper limit value, the liquid level sensor converts the liquid level information into an electrical signal again and transmits it to the control system. After receiving the high liquid level signal, the control system will issue a command to close the electric valve 10 on the water supply pipe 8 to stop water replenishment.
[0028] With the automatic sewage discharge function, when impurities accumulate to a certain level in the water tank 3, the equipment will be stopped and the electric valve 10 on the sewage discharge pipe 9 will be opened to discharge the accumulated impurities. The scraper 4 in the water tank 3 is connected to the side plate 1 of the annular cooler trolley and moves with the trolley. During the movement, the scraper 4 will scrape off the impurities in the water tank 3 to prevent impurities from accumulating at the bottom of the water tank 3, thereby maintaining the cleanliness of the water in the water tank 3, ensuring that the water seal effect is not affected, and extending the service life of the sealing device.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
