Double sealing sliding plates for sintering pallet

Abstract

The invention relates to a trolley sealing device of agglomerating machine or roast machine, particularly a agglomerating machine trolley double sealing loose plate, including a trolley loose plate, a loose plate groove, a locating shaft, a cylinder spring, the characteristic of the invention resides in the sealing metal strip installed on the double sides of the trolley loose plate. The sealing metal strip is installed in the wedge gap between the trolley loose plate and the loose plate groove. When the gap between the loose plate and the loose plate groove leaks air, the sealing metal strip seals the gap between the loose plate and the loose plate groove effectively, under the action of dead weight and bellows negative pressure for preventing air leakage. The higher the negative pressure of the bellows is; the better of the effect of the metal strip has. Compared with the prior art, the agglomerating machine trolley double sealing loose plate provided by the invention has good leak tightness, simple structure, which reduces the air leakage ratio of the agglomerating machine, and reduces the effect of air leakage on the edge of agglomerating machine to the uneven agglomerating speed. The invention can improve the speed of agglomerating machine or roast machine, and improve productivity and quality of agglomerating machine or roast machine. The invention can effectively prevent air leakage and bulge of trolley loose plate and is suitable for trolley loose plate of agglomerating machine or roast machine in every iron works.

Description

technical field [0001] The invention relates to a moving sealing device for a trolley of a sintering machine or a roasting machine, in particular to a double-sealed traveling plate of a trolley of a sintering machine. Background technique [0002] At present, the seal of the sintering machine or roasting machine trolley is usually in the form of a spring travel plate and a leaf spring. A certain gap must be maintained between the travel plate of the spring travel plate and the travel plate groove. Due to the large negative pressure of the bellows, the sintering machine or The air leakage rate of the roasting machine rises, accounting for about 17% of the total air leakage rate of the sintering machine or roasting machine. Affected by the air leakage on both sides of the trolley, the sintering speed on the trolley is uneven, which greatly affects the speed of the sintering machine or roasting machine. Impact.

[0002] At present, the seal of the sintering machine or roasting machine trolley is usually in the form of a spring travel plate and a leaf spring. A certain gap must be maintained between the travel plate of the spring travel plate and the travel plate groove. Due to the large negative pressure of the bellows, the sintering machine or The air leakage rate of the roasting machine rises, accounting for about 17% of the total air leakage rate of the sintering machine or roasting machine. Affected by the air leakage on both sides of the trolley, the sintering speed on the trolley is uneven, which greatly affects the speed of the sintering machine or roasting machine. Impact

The elasticity of the leaf spring swimming plate is poor, the expansion and contraction of the swimming plate is small, and the heat treatment process of the leaf spring is relatively difficult, so the life of the leaf spring is short. After a short period of time, the elasticity of the swimming plate weakens and the sealing Significantly less effective
