Embodiment Construction
[0023] Such as figure 1 An automatic follow-up head and tail sealing device of a sintering machine is shown, its structure is: a rolling bearing is fixed in the middle of the sealing roller 1, the rolling rod is covered with a 40-60mm thick high temperature resistant elastic material, and the elastic material is connected with the outside and the sealing belt 2 Contact and rotate under its drive. One end of the horizontal connecting rod 5 is welded on the bearing, the other end is hingedly connected with the side column 8, and the middle part is connected with the hydraulic cylinder 3, and the horizontal connecting rod 5 together with the sealing roller 1 can move up and down around the side column 8 under the action of the hydraulic cylinder 3 . The other end of the hydraulic cylinder 3 is hingedly connected with the pallet 13 welded on the side column 8 . Side column 8 is fixed on the bottom support frame 12, and bottom support frame 12 bears all device weights, and is fix...

The invention discloses an automatic servo head-and-tail sealing device for a sintering machine. The automatic servo head-and-tail sealing device for the sintering machine comprises a head sealing device body and a tail sealing device body. The head sealing device body and the tail sealing device body are identical in structure and installing way. Each sealing device body comprises an external sealing strip, sealing rollers, hydraulic cylinders, a driving drum, transverse connecting rods, a telescopic wheel, a supporting roller, stand columns, steering rollers and a bottom supporting frame, wherein one end of each transverse connecting rod is connected with the corresponding sealing roller covered with a high-temperature-resistant elastic body, the other end of each transverse connecting rod is hinged to the corresponding lateral stand column, the middle portion of each transverse connecting rod is connected with the corresponding hydraulic cylinder, and a pressure sensor is arranged between the middle portion of each transverse connecting rod and the corresponding hydraulic cylinder; the connecting rods and the sealing rollers are pushed by the hydraulic cylinders to move up and down around the lateral stand columns; and the driving drum and the telescopic wheel are mounted on the two sides of the bottom supporting frame correspondingly. The sealing device bodies are wrapped with the external sealing strips and driven by a servo motor to move along with a trolley. The rotating speed of the automatic servo head-and-tail sealing device can be adjusted automatically according to the operating speed of the trolley, so that the automatic servo head-and-tail sealing device moves along with the trolley in real time, and friction between the trolley and the sealing device is greatly reduced; and meanwhile, the sealing rollers can stretch deep into the space between cross beams, and thus a better sealing effect is achieved.
Description
technical field [0001] The invention relates to the technical field of metallurgy, in particular to a novel sintering machine head and tail sealing device Background technique [0002] The research and development of sintering machines in our country started relatively late, and the research on plugging air is correspondingly backward, but the relative technological development is relatively rapid. As far as the head and tail sealing devices of sintering machines currently used in China are concerned, most of them are imported from abroad, and are followed by production practice and technical improvement to meet production needs. The air leakage rate of sintering machines in developed countries such as Europe, America, and Japan is generally controlled at about 30%, and some Japanese companies can reach a minimum of 20%, while the general air leakage rate in China is between 50% and 70%. [0003] The main air leakage parts of the sintering machine are: the slideway between ...
