Description

The first-level water-sealed anti-heat transpiration shield device of the sintering machine trolley

technical field

The invention relates to an integral thermal insulation and sealing device for a trolley in the sintering section of a sintering machine, in particular to a first-stage water-sealed heat-proof transpiration shield device for a trolley of a sintering machine.

Background technique

In the metallurgical industry, sintering plays an important role as the upstream process of ironmaking. Whether the sintering material is fully burned directly affects the energy consumption during smelting, so it is necessary to ensure that the sintering material is fully burned; the current popular sintering method in the metallurgical industry is The sintered material is distributed on the sintering machine trolley, and then the flame is burned through the sintering machine, and at the same time, the blower is used for air convection at the bottom of the sintering machine trolley, so that the high-temperature gas in the upper part of the sintered material is convected from the upper part of the trolley to the bottom of the trolley , so as to drive the sintering material in the lower part of the trolley to fully burn.

In the actual production process, since the side of the sintering machine trolley is in contact with the slide plate, the two workshops are in simple plane contact. Due to the wear of the slide plate or impact deformation, the gap between the two becomes larger, and the heat of the sintering material is along the convection process. The gap escapes, and only a small part of the heat is exchanged through the bottom of the trolley, causing the sintered material at the bottom of the trolley to not be fully burned, thereby affecting the use of the next process. Therefore, a new type of sealing temperature device must be designed to keep the sintered material warm.

After searching, no publications of the same technology are found in this technical field.

The shield completely covers the space at the upper end of the sintering trolley and the top of the shield is high On the side baffles of the trolley, the two side walls of the shield are provided with adjustment windows for adjusting the air flow, which serve as cold air intakes.

It also includes a sealing steel plate, which is sealed between the trolley guide rail and the trolley foundation and between the trolley guide rail and the bottom sealing strip guide rail of the trolley.

A bottom sealing strip of the trolley is arranged between the top of the bottom sealing strip guide rail of the trolley and the trolley.

The side baffles, shields, U-shaped water seal grooves, brackets, sealing steel plates, trolley guide rails, trolley bottom sealing strip guide rails, and trolley bottom sealing strips surround each other to form a cold wind isolation area.

The U-shaped water seal tank adopts a combined structure. On the side of the trolley, a water tank slot is opened on the left side of the U-shaped water seal tank, and a water tank insert plate is arranged on the right side. Pour water into the sink to seal it.

Compared with the prior art, the present invention has the following beneficial effects:

The working principle of this device is to seal the sintering stage of the sintering machine with a sealed steel plate, and seal the bottom space between the trolley walking wheel guide rail and the trolley sealing strip slide rail, and at the same time install brackets on the foundations on both sides of the trolley, and install the water seal tank on the bracket after assembly Above, the shield is placed in the U-shaped tank, and the water is used to isolate the air from entering. The shield moves in the tank through the walking wheels. There is an adjustment window for adjusting the air flow on the side wall of the shield to adjust the air intake.
