Description

Technical Field

[0001] This utility model relates to the field of sintering trolley technology, and in particular to a high-efficiency self-sealing sintering trolley. Background Technology

[0002] The sintering trolley is the main operating component of the sintering machine. The sintering trolley forms a rotating chain between the head and tail wheels of the sintering machine. Its working process is as follows: it receives the sintering mixture in the upper horizontal section, and after preheating and ignition, sintering, cooling and turning, it returns to the head wheel to form a transmission cycle, thus achieving the purpose of sintering the material.

[0003] Existing Chinese patent document CN202122403439.7 discloses a sintering trolley grate bar pressing structure and a sintering trolley. The sintering trolley grate bar pressing structure includes a trolley sideboard, a grate bar pressing component, and end grate bars fixed to the grate bar pressing component. The grate bar pressing component includes a fixing part and a pressing part. The fixing part is fixed to the trolley sideboard. The end grate bars have grooves. The pressing part extends through the trolley sideboard into the groove and abuts against the inner wall of the groove. The upper surface of the pressing part is flush with the upper surface of the end grate bars. The aforementioned sintering trolley grate bar pressing structure has grooves on the end grate bars. The pressing part of the grate bar pressing component extends into the grooves and abuts against the end grate bars, making the upper surface of the pressing part flush with the upper surface of the end grate bars. This reduces the wear of the grate bar pressing component by the material. Furthermore, the pressing part is pressed into the end grate bars, which does not occupy the space above the grate bar surface of the trolley, increasing the loading capacity of the trolley and improving the output of sintered ore.

[0004] However, the above-mentioned patent has certain defects in use. There will be gaps between multiple panels during the assembly process. These gaps will cause air leakage between the trolley bodies. A large amount of air leakage means that some air volume does not pass through the sintering trolley material layer, which affects the output and also wastes electricity.

[0005] To address these issues, a highly efficient self-sealing sintering trolley is proposed. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology and solve the problem of air leakage caused by gaps in the assembly of multiple panels, this utility model provides a high-efficiency self-sealing sintering trolley.

[0007] This utility model is achieved using the following technical solution:

[0008] A high-efficiency self-sealing sintering trolley includes trolley wheels, mounting plates, grate bars, side rails, and trolley beams. Multiple trolley beams are arranged horizontally and evenly. The trolley wheels are fixed to both ends of the trolley beams and placed on a track. The mounting plates are fixed to both ends of the trolley beams, and the side rails are fixed to the upper end of the mounting plates. Multiple side rails are provided, each including an upper side rail and a lower side rail. Mounting grooves are respectively located at the lower end of the back of the upper side rail and the upper end of the back of the lower side rail. Bolts are installed in the mounting grooves, and the upper and lower side rails are fixedly connected by bolts.

[0009] A front sealing block is provided at the connection between the upper and lower rails. The front of the upper and lower rails is provided with a slot. The back of the front sealing block is provided with two locking blocks. The front sealing block is engaged in the slot by the locking blocks. A guide post is provided on one side of the front sealing block and a connecting hole is provided on the other side. When multiple rails are assembled, the guide post is inserted into the connecting hole.

[0010] The back of the railing is provided with a rear sealing plate, which is fixed to the vertical connection of multiple railings by bolts.

[0011] The top of the upper panel is provided with multiple anti-crack strips.

[0012] The upper and lower panels have cooling zones on their backs, and cooling blocks are fitted into the cooling zones. The cooling blocks are hollow inside and have liquid inlets that are connected to the interior of the cooling blocks.

[0013] The bottom panel has a guide post at the top, which is fixed to the bottom panel, and the bottom of the top panel has a corresponding guide hole.

[0014] The present invention has the following advantages over the prior art:

[0015] 1. By setting a front sealing block and a rear sealing plate between the railings, the front sealing block is used to seal the lateral connection between the upper and lower railings, and the rear sealing plate is used to seal the assembly connection between multiple railings. The innovative railing structure and sealing mechanism effectively improve the sealing performance of the workshop, reduce air leakage, thereby improving sintering efficiency and reducing energy consumption.

[0016] 2. By setting crack-stopping measures on the top of the upper panel and cooling blocks on the back of the upper and lower panels, the durability and stability of the panel are enhanced, and its service life is extended. Attached Figure Description
