Description

Technical Field

[0001] The utility model belongs to the technical field of rotary kiln feeding devices, in particular to a rotary kiln feeding dish. Background Art

[0002] The main function of the rotary kiln feeding device is to continuously add process raw materials, reducing agents, catalysts, etc. into the cylinder to achieve the process purpose and realize the normal operation of the process operation. In order to achieve the purpose of transporting materials in the kiln during the rotation process, the rotary kiln is mostly arranged at a certain slope, and the feeding device into the kiln is mostly arranged at the end face of the high-end cylinder. Under the action of the continuous rotation of the cylinder, the material continuously rolls in the cylinder and moves to the lower end. In this process, the material forms a continuous material line in the cylinder, and the movement trajectory of the material line covers the entire inner surface of the cylinder. At present, the addition of materials falls directly from a high place into the end face of the high-end cylinder of the rotary kiln through the discharge port of the feeding device, which leads to uneven feeding on the one hand, and the material addition can only be adjusted by the feeding device. Uneven feeding is easy to cause insufficient roasting of materials in the rotary kiln; on the other hand, the material falls directly, and the refractory material at the end face of the rotary kiln is directly impacted. Long-term scouring is easy to damage the refractory material at the end face. The refractory material damage can only be repaired by stopping the kiln, and the maintenance cycle is long.

[0011] 2. The feeding dish partition ensures that the materials in each separated space are basically equal, so that the materials are added evenly and the materials are fully roasted in the rotary kiln.

[0012] 3. The baffle of the feeding dish ensures that a certain amount of material is always kept on the curved surface of the feeding dish during the bottom feeding process, which reduces the wear of the feeding dish caused by the impact of the material and increases the service life of the feeding dish.

[0016] The present invention is further described below with reference to the embodiments.

[0017] like Figure 1 As shown, a rotary kiln feeding dish is assembled from a plurality of feeding dish components to form a feeding dish cylinder, the outer diameter of the feeding dish cylinder is the same as the inner diameter of the rotary kiln; the feeding dish component comprises a connecting port 1, a connecting bolt 2, and a feeding dish 3; the connecting port 1 is fixedly connected to the feeding dish 3 by the connecting bolt 2, and the connecting port 1 is fixed in the refractory material of the rotary kiln; the feeding dish 3 comprises a feeding dish back plate 31, a feeding dish arc plate 34, a feeding dish partition 32, and a feeding dish baffle 33, the feeding dish back plate 31 is fixedly connected to the connecting port 1 by the connecting bolt 2, the feeding dish arc plate 34 is fixedly connected to the lower end of the feeding dish back plate 31 to form a material storage space, a plurality of feeding dish partitions 32 are arranged at intervals in the material storage space, one end of the feeding dish partition 32 is fixed on the feeding dish arc plate 34, and the other end is fixed on the feeding dish back plate 31, and the feeding dish partitions 32 are spaced at the same distance to ensure that the materials in each separated space are basically equal.

[0018] The connection port 1 includes a connection port rib plate 11 and a connection port back plate 12. The connection port back plate 12 is connected to the feeding dish back plate 31 through connecting bolts 2. A plurality of connection port rib plates 11 are fixedly connected to the connection port back plate 12. The connection port rib plates 11 are buried in the refractory material, and the connection port back plate 12 is in contact with the outer surface of the refractory material.

[0019] The height of the feeding dish baffle 33 is 30-50mm. Only when the material is higher than the baffle can the material enter the rotary kiln cylinder. This ensures that a certain amount of material is always kept in the arc plate of the feeding dish during the bottom feeding process, reducing the wear of the feeding dish components caused by the impact of the material.

[0020] The specific working process is as follows: the connection port rib plate 11 and the studs of the connection bolts 2 are directly buried in the refractory material when the rotary kiln refractory material is laid, the connection port back plate 12 is fitted with the outer surface of the refractory material, and the connection ports 1 are installed in turn. Multiple connection ports 1 are assembled into a concentric circle with the rotary kiln cylinder. After the connection ports 1 are fixed, after the strength of the refractory material reaches the operating requirements, the bolt holes of the back plate 31 of the feeding dish are passed through the studs of the connection bolts 2 of the back plate 12 of the connection port to connect the feeding dish 3 with the connection port 1, and the multiple feeding dishes 3 are installed in turn to be assembled into the same concentric circle as the rotary kiln.

[0021] After the rotary kiln is officially put into operation, the material falls directly from a high place into the feeding dish 3. As the rotary kiln operates, the feeding dish operates synchronously, so that the material in the space separated by the partition 32 of each feeding dish is basically equal. When a certain amount of material is stored in the feeding dish partition 32, the feeding dish moves to the feeding dish baffle 33 with the centrifuge. When the material is spread to a height exceeding the feeding dish baffle, the material enters the rotary kiln evenly with the movement of the rotary kiln. The material moves gradually from the high end to the low end in the rotary kiln, and is gradually roasted in the process. When it runs to the low end, the material is roasted.
