Description

Technical Field

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

[0002] After the lithium ore is roasted in a rotary kiln, the material needs to be transferred out and transported to the subsequent production line. However, dust is easily generated when the rotary kiln is discharging the material and during the transportation process.

[0003] In the prior art, a sealed container such as a receiving box is used as a material storage device for a rotary kiln to prevent dust, such as the patent with publication number CN217686529U. The rotary kiln discharging device disclosed in the patent is specifically that the discharging box rotates synchronously with the kiln body. After the material rotates from one side of the discharging guide plate to a high position, it slides to the other side along the discharging guide plate and enters the receiving box from the discharging port. The diameter of the shaft cylinder is the same as the diameter of the discharging port. In the material receiving state, the two are butted and rotate synchronously; a plug plate is set at the discharging port of the discharging box. When the receiving box is full of materials and an empty receiving box needs to be replaced, the plug plate is closed, and the locking buckle is opened, so that the receiving box can be disengaged, thereby realizing the replacement of the box under closed conditions;

[0004] However, although the material receiving box plays a role in dust prevention when the rotary kiln is discharging materials, it needs to be replaced. In the actual production line, the rotary kiln is in continuous operation and will discharge materials continuously. Therefore, the method of using a material receiving box to receive materials cannot meet the needs of continuous production, and the disassembly and replacement of the material receiving box is time-consuming and labor-intensive.

[0005] Based on the above description, there is an urgent need for a rotary kiln discharging device that can effectively prevent dust and continuously discharge and transport materials. Utility Model Content
