Problems solved by technology
like figure 1 As shown, the sealing plates of the sealing body in the prior art are all fixed. In order to prevent the moving trolley from colliding when entering and leaving the sealing body, a certain gap is provided between the sealing plate at the end of the sealing body and the body of the trolley. The gap, which causes serious air leakage at the end of the sealing body, seriously reduces the sealing effect of the sealing body
In addition, the sealing plate at this end is also provided with a lower space for the wheels of the trolley to pass through, and there is no seal, which also causes serious air leakage

The invention provides a sealing device for an end part of a full sealing body allowing the access of a trolley. The sealing device comprises two sealing plates relatively arranged at the end part of the sealing body, wherein the upper parts of the sealing plates form an upper space allowing the access of the trolley body; the lower parts of the two sealing plates form a lower part allowing the access of the wheel of the trolley; the sealing device further comprises an upper flexible sealing body with one end fixed on the upper parts of the sealing plates, and / or a lower flexible sealing body with one end fixed on the lower parts of the sealing plates and / or fixed on the ground; and the upper flexible sealing body is used for sealing the gaps between the upper parts of the sealing plates and the side surfaces of the trolley body, and the lower flexible sealing body is used for sealing the lower space. According to the invention, through arranging the upper and the lower flexible sealing bodies, the full sealing for the end part of the full sealing body is realized so as to reduce the air leakage rate.
Description
technical field [0001] The invention relates to an auxiliary device for sintering equipment in the iron and steel metallurgy field, in particular to an end sealing device for a sealing body for trolleys to enter and exit. Background technique [0002] In iron and steel smelting, the production of sintered pellets is one of the important processes, which provide high-quality raw materials for blast furnace ironmaking. In order to improve the energy utilization rate in the sintering process, sintering pellet workers have been working hard and exploring many methods. It is necessary to put the trolley with the material into the sealing body together with the material for sintering. For example, the Chinese utility model patent No. 02243431.3 discloses an energy-saving air-leakage-free sintering machine, which is composed of a trolley and a bellows under it. There is a hot air shielding cover with a hot air drainage pipe connected in the middle, and vertical sealing plates are...
