Description

Technical Field

[0001] The utility model belongs to the technical field of sintering equipment, and more specifically relates to a sealed sintering machine. Background Art

[0002] In the metallurgical industry, sintering machines are key equipment for high-temperature sintering of sintering raw materials such as fine ore, fuel, and flux. Their performance directly affects the quality and output of sintered ore. However, existing sintering machines often have numerous sealing issues during operation, seriously impacting their efficient and stable operation. Currently, sealing in conventional sintering machines primarily faces the following challenges:

[0003] First, the seal between the sintering machine trolley and the bellows is a key difficulty. During the sintering process, the trolley continuously runs on the track. Due to the certain gap between the trolley and the track, coupled with the high temperature and high pressure generated during the sintering process, and the wear of the materials, it is difficult to maintain a good seal between the trolley and the bellows for a long time. If the seal is poor, a large amount of air will leak from the connection between the trolley and the bellows. On the one hand, this will reduce the negative pressure of the exhaust during the sintering process, affecting the sintering effect and reducing the quality of the sintered ore. On the other hand, the leaked air will also carry away a large amount of heat, increasing energy consumption and raising production costs.

[0004] Secondly, sintering machines are composed of numerous trolleys, resulting in significant air leakage through gaps between them and between trolley guardrails. Furthermore, existing sealing mechanisms have structural design deficiencies. Some sealing devices are complex, difficult to install and maintain, and expensive. Furthermore, some sealing materials lack ideal heat and corrosion resistance, making them susceptible to damage under prolonged high-temperature, high-pressure, and chemically corrosive conditions, shortening the service life of the sealing device.

[0005] In summary, the existing sintering machine has poor sealing performance, which seriously affects the production efficiency, product quality and environmental friendliness of the sintering machine. A new type of sintering machine sealing mechanism is urgently needed to solve these problems. Utility Model Content

[0027] Now, the sealed sintering machine provided by the present utility model will be described.

[0028] As Figures 1 to 3 shown, the sealed sintering machine provided by the first embodiment of the present utility model includes an air box 84, a trolley 81, two trolley baffles 82, a top plate 87 and a plurality of elastic sealing mechanisms. The trolley 81 is arranged above the air box 84 for running on the air box; the two trolley baffles 82 are respectively located on both upper sides of the trolley 81; the top plate 87 is arranged above the two trolley baffles 82; the plurality of elastic sealing mechanisms are arranged between the trolley 81 and the trolley baffles 82 and between the trolley baffles 82 and the top plate 87 and have vertical elasticity; wherein, the trolley 81, the two trolley baffles 82, the top plate 87 and the plurality of elastic sealing mechanisms enclose a closed space, thereby improving the sealing performance of the sintering machine and being more conducive to environmental protection.

[0029] Compared with the prior art, the sealed sintering machine provided in this embodiment can prevent the dust generated by the materials from leaking out by enclosing a closed space with the trolley 81, two trolley baffles 82, the top plate 87 and a plurality of elastic sealing mechanisms. At the same time, the elastic sealing mechanisms with vertical elasticity buffer the connection parts between various components, enabling the connection parts to move to a certain extent, and preventing the sealing parts from loosening or disconnecting due to mechanical vibration during the operation of the sintering machine, resulting in dust leakage. Thus, the sealing performance of the sintering machine is improved, which is more beneficial to environmental protection. Moreover, it can be used in high-temperature, high-pressure and chemical corrosion environments for a long time, which is beneficial to improving the sealing effect and service life of the sintering machine.

[0030] As Figure 1 shown, a specific implementation manner provided by the present invention on the basis of the first implementation manner is as follows.

[0031] The sealed sintering machine further includes a side sealing plate 83, which is arranged outside the trolley 81 and the trolley baffle 82 and is connected to the top plate 87.

A side sealing cavity is formed between the side sealing plate 83, the top plate 87, the trolley baffle 82 and the trolley 81 to form a sealing cavity outside the internal closed space. When dust leakage occurs on the trolley baffle 82, it can also prevent dust from leaking out, and can also play a certain role in heat preservation and protection.

To reduce wear, a reinforcing piece can also be provided on the limiting hole 61.

[0042] A support member 71 is provided between the elastic member 40 and the first connecting plate 10.
