Description

Technical Field

[0001] This utility model belongs to the field of sintering machine technology, and in particular relates to a novel fully enclosed sealing device for sintering machines. Background Technology

[0002] A sintering machine is a specialized piece of equipment used for the sintering of iron ore powder. It primarily serves the sintering production process in large-scale ferrous metallurgical sintering plants. This machine can sinter concentrates and rich ore powders of various compositions and particle sizes into blocks, effectively reducing the content of harmful impurities such as sulfur and phosphorus in the ore. At the same time, through the high-temperature sintering process, the sintering machine can significantly improve the physical properties and chemical stability of the ore, making it more suitable for subsequent smelting and processing.

[0003] During the operation of a sintering machine, wear and tear on the pipes, thermal expansion and contraction, and poor sealing of the ash discharge system can easily lead to air leakage, which increases the energy consumption of the sintering machine. Air leakage allows air to enter the sintering system, reducing the system's working negative pressure and thus increasing the power consumption of the main exhaust fan. Furthermore, air leakage can alter the chemical composition and physical properties of the sinter, leading to a decline in the quality of the sinter. To address these issues, a new type of fully enclosed sealing device for sintering machines is urgently needed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that during the use of a sintering machine, air leakage is easily caused by pipe wear, thermal expansion and contraction deformation, and poor sealing of the ash discharge system, which increases the energy consumption of the sintering machine, allows air to enter the sintering system, reduces the working negative pressure of the system, thereby increasing the power consumption of the main exhaust fan, and causes changes in the chemical composition and physical properties of the sinter, resulting in a decline in the quality of the sinter. Therefore, a novel fully enclosed sealing device for a sintering machine is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel fully enclosed sealing device for a sintering machine, comprising a wind box, sealing components on both sides of the wind box, baffles fixedly connected to both ends of the wind box, a material insertion plate inside the wind box, and an ash discharge component at the bottom of the wind box.

[0006] The sealing assembly includes a fixing frame, a sealing top plate at the bottom of the fixing frame, and sealing side plates on both sides of the air box. The sealing top plate and the sealing side plates are threadedly connected to bolts through threaded holes opened in them.

[0007] As a further description of the above technical solution:

[0008] One end of the fixed frame is fixedly connected to the bellows, and through holes are opened at both ends of the fixed frame. The sealing top plate is fixed to it by bolts, and an observation window and maintenance port are opened on a part of the surface of the sealing side plate.

[0009] As a further description of the above technical solution:

[0010] The bellows has threaded holes on both sides, and the sealing side plate is fixed to the bellows by bolts threadedly connecting to the threaded holes in the bellows.

[0011] As a further description of the above technical solution:

[0012] The ash unloading assembly includes an ash hopper, and a conveying pipe is fixedly connected to the bottom end of the ash hopper.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the conveying pipe is equipped with two ash discharge valves, and a chute is fixedly connected to the bottom end of the conveying pipe.

[0015] As a further description of the above technical solution:

[0016] The top of the ash hopper is fixedly connected to the bellows, and the ash hopper communicates with the inner cavity of the bellows through a through hole at the bottom of the bellows.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, a sealing side plate is provided inside. During the use of the air box, the sealing side plate is fixed to the air box with bolts, and the sealing top plate is fixed to the fixing frame with bolts, thereby sealing the top of the air box. This design enhances the sealing performance of the sintering machine, thereby reducing air leakage and preventing it from affecting the sintering machine. At the same time, during use, the interior can be observed through the observation window, and maintenance can be carried out through the inspection port, making it convenient for staff to maintain.

[0019] 2. In this utility model, by installing an ash discharge valve inside, during use, the dust in the air box falls into the ash hopper. At the same time, by opening the ash discharge valve, the dust falls into the chute through the conveying pipe and is discharged. Through this design, dust can be discharged in a simple way, which facilitates the cleaning of dust by the staff, thereby reducing the labor intensity of the workers, ensuring the health of the workers and avoiding their overwork.
