Embodiment 1
[0033] During the internal operation of the sintering machine, it is in a negative pressure state, so that the wear-resistant flexible module slide rail 22 is offset to the inside of the sintering machine as figure 2 Deviated to the right, the top end of the wear-resistant flexible module slide rail slides against the bending part of the sealed upper slideway to make the seal more tight. Adjust the hydraulic pressure or air pressure so that the elastic support device 23 holds up the wear-resistant flexible module slide rail 22 and just sticks to the upper sealing slideway 21. Through pressure adjustment, the pressure between the upper sealing slideway 21 and the wear-resistant flexible module slide rail 22 Just keep the seal slightly, and there is not much friction when sliding against each other. The present invention only plays a sealing role but not a supporting role, and the trolley has another supporting structure. Since the frictional force produced by the whole set of...

The invention discloses a fluid elasticity compensation micro-contact sealing device of a sintering machine trolley track. The fluid elasticity compensation micro-contact sealing device of the sintering machine trolley track comprises a breast board sliding plate of a trolley, an upper frame of an air bellow and a sealing device connecting the breast board sliding plate and the air bellow, whereinthe sealing device comprises an upper sealing slideway, a wear-resistant flexible module sliding rail, an elastic supporting device and a lower sealing slideway clamping groove, the sealing upper slideway is fixed at the lower end of the breast board sliding plate, the sealing lower slideway clamping groove is fixed on the upper frame through bolts, the elastic supporting device is extruded and fixed in the sealing lower slideway clamping groove after being filled and expanded, the elastic supporting device comprises a flexible cavity and a slide way boss, the flexible cavity is of a hollow closed pipeline structure, a cavity wall in the middle of the upper part of the flexible cavity protrudes upwards to form the slide way boss, the cross section of the wear-resistant flexible module sliding rail is inverted U-shaped, a slideway groove is formed inside the wear-resistant flexible module sliding rail, the groove completely covers the slideway boss and is fixed in a threaded connectionmanner, and the wear-resistant flexible module slide rail makes contact with and seals the bending part of the upper slideway to slide. According to the fluid elasticity compensation micro-contact sealing device of the sintering machine trolley track, fluid elasticity is used for sealing the space between the trolley breast board sliding plate and the air bellow, and the effect is remarkable.
Description
technical field [0001] The invention relates to the field of hot sintering trolley systems in the metallurgical industry, in particular to a fluid elastic compensation micro-contact sealing device for a sintering machine trolley track. Background technique [0002] At present, the sealing system of the sintering machine trolley mainly adopts rubber flexible seal. Traditional rubber seals cannot meet the production needs on site. The working principle of the sintering machine trolley is: use the blower to send cold air into the bellows under the trolley, the cold air passes through the bellows to cool the hot sinter on the trolley and exchange heat with it, and the hot sinter gradually cools to the specified temperature . However, the trolley and the bellows are relatively moving, and there must be enough space between the trolley and the bellows to prevent interference. Therefore just need to do an elastic sealing device to block up this gap to the gap between trolley and...
