Description

Technical Field

[0001] The utility model relates to the technical field of rotary kilns, in particular to a rotary kiln feeding bin. Background Art

[0002] A rotary kiln refers to a rotating calcining kiln (commonly known as a rotary kiln). A rotary kiln is composed of processes such as gas flow, fuel combustion, heat transfer, and material movement. There are cement kilns and lime kilns. Cement kilns are mainly used to calcine cement clinker, and are divided into two categories: dry-process cement kilns and wet-process cement kilns. Lime kilns (i.e. active lime kilns) are used to roast active lime and light-burned dolomite for steel mills and ferroalloy plants. The raw materials of rotary kilns are usually placed in the feed bin.

[0003] The existing feeding bin usually has a conical bottom. When the raw materials agglomerate, the raw materials will accumulate and block the discharge port, resulting in the inability to feed the raw materials into the rotary kiln, affecting the production efficiency of the rotary kiln. Utility Model Content

[0007] Preferably, a ladder is provided on the left side of the silo, and the ladder is welded to the left side of the silo and to the mounting beam 1 through a fixing rod. By providing the ladder, it is convenient to manually go up to the top of the silo to open the cover.

[0008] Preferably, the anti-blocking mechanism is composed of two mounting seats, an anti-blocking motor, a round shaft and a breaking rod. The two mounting seats are symmetrically mounted at the bottom of the silo. An anti-blocking motor is mounted on the outside of the left mounting seat. The output shaft of the anti-blocking motor is connected to a round shaft through a flange. The round shaft passes through the discharge pipe and is fixed to the right mounting seat through a bearing seat. The round shaft is located in the discharge pipe and four groups of breaking rods are staggered in a ring array. By setting up a blocking mechanism, the fuel at the silo discharge port can be broken up to prevent blockage.

[0009] Preferably, two rectangular iron blocks are symmetrically mounted on the right end of the conveying impeller shaft. By setting the two rectangular iron blocks, the block fuel can be discharged from the discharge nozzle.

[0010] Preferably, the control box is installed outside the right support leg, and the control box is electrically connected to the conveying motor and the anti-blocking motor respectively. By setting the control box, it is convenient to control the start and stop of the conveying motor and the anti-blocking motor as a whole.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model is provided with an anti-blocking mechanism. When the rotary kiln needs to be fed, the anti-blocking motor is started through the control box. The anti-blocking motor drives the round shaft to rotate through the flange. The rotation of the round shaft drives four groups of staggered breaking rods to rotate to break the raw materials, thereby breaking the raw materials at the silo discharge port and avoiding blockage of the raw materials, without affecting the feeding production of the rotary kiln.
