Description

Technical Field

[0001] The utility model relates to the technical field of catalyst roasting equipment, in particular to a two-stage rotary kiln roasting equipment. Background Art

[0002] A rotary kiln refers to a rotating calcining kiln, which belongs to the category of building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to the materials they process. Cement kilns are mainly used to calcine cement clinker, and are divided into two categories: dry process cement kilns and wet process cement kilns. Metallurgical chemical kilns are mainly used in the metallurgical industry for magnetization roasting of lean iron ore in steel mills, oxidation roasting of chromium and nickel iron ore, roasting of high-alumina vanadium ore in refractory plants, roasting of clinker and aluminum hydroxide in aluminum plants, and roasting of chromium ore sand and chromium ore powder in chemical plants. Lime kilns are used to roast active lime and light-burned dolomite for use in steel mills and ferroalloy plants.

[0003] At present, there is an existing two-stage rotary kiln roasting equipment (such as patent number: CN215063623U), which discloses a two-stage rotary kiln roasting equipment, including rotary kiln 1, rotary kiln 2 and a mounting frame, wherein the rotary kiln 1 is installed on the ground, the rotary kiln 2 is installed on the mounting frame, and the rotary kiln 2 is located directly above the rotary kiln 1, the heat inside the rotary kiln 1 is radiated to the rotary kiln 2, the ends of the rotary kiln 1 and the rotary kiln 2 are both provided with connecting ends, the connecting ends are rotatably connected to the rotary kiln 1 and the rotary kiln 2, the connecting ends on the rotary kiln 1 and the rotary kiln 2 are both provided with material guide ports, the material guide ports of the rotary kiln 1 and the rotary kiln 2 are connected by a material guide pipe, and are divided into upper and lower rotary kilns, and the upper and lower connecting parts are provided with material guide ports, the rotary kiln 2 can be used for catalyst drying, the rotary kiln 1 is used for catalyst roasting, and the heat generated by the heating of the rotary kiln 1 is radiated to the rotary kiln 2, which can be used for drying the rotary kiln 2, thereby reducing the length of a single cylinder.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] The rotary kiln of the existing device is directly installed on the bottom surface, and is not provided with an angle adjustment device. When different materials need to be baked, the rotary kiln needs to have different angles, otherwise the material transportation may be slow, which may cause the rotary kiln to be blocked. Therefore, the rotary kiln of the existing device has the risk of blockage.

[0006] Although the rotary kiln 2 of the existing device is installed on a mounting frame and has certain supports at both ends of the rotary kiln 2, no supporting device is provided in the middle section of the rotary kiln. When the rotary kiln 2 bakes materials, the middle section of the rotary kiln 2 will be under great pressure. If the middle section is not provided with a supporting structure, the rotary kiln 2 may not be able to withstand the pressure when there is a large amount of material inside, thereby breaking and disintegrating.

[0012] Preferably, the docking head matches with the first docking groove.

[0013] Preferably, the discharge pipe is fixedly connected to a material guide head installed on the second rotary kiln, and the discharge pipe is arranged at the bottom of the material guide head.

[0014] Preferably, the feed pipe is fixedly connected to a material guide head installed on the rotary kiln, and the feed pipe is arranged on the top of the material guide head.

The high-temperature resistant accordion plate is used to seal the gap between the feed funnel and the discharge pipe to prevent heat from dissipating quickly and prevent materials from flowing out of the gap between the feed funnel and the discharge pipe, thereby solving the problem of easy clogging caused by the inability to adjust the angle of the rotary kiln in the existing device.

[0019] Second, the rotary kiln 2 is supported by bearings, and the support plate and the fixed plate provide support for the bearings. The multiple supports prevent the rotary kiln 2 from collapsing when adding more materials, thereby solving the problem that the rotary kiln 2 of the existing device is easy to break and disintegrate.

The feeding mechanism 7 includes a discharge pipe 701 and a feed pipe 702.

[0030] The docking head 502 matches with the first docking groove 403 .

[0031] The discharge pipe 701 is fixedly connected to the material guide head 6 installed on the rotary kiln 2 3 , and the discharge pipe 701 is arranged at the bottom of the material guide head 6 .
