Thick-bed sintering is an important and widely used sintering technology, which has the advantages of improving the strength of sintered ore and reducing sintering fuel consumption. However, the application of thick-bed sintering technology also faces some difficulties.

[0003] Chinese utility model patent: Publication number CN205275659U discloses a material distribution device for improving the sintering yield of ultra-thick material layers, which is installed between the sintering material distributor and the igniter.

[0004] In the existing technology, when CN205275659U is in use, the problem of unbalanced heat supply between the upper and lower sintering layers caused by "automatic heat storage" is solved, the heat supply and mineralization time of the upper layer are increased, the strength of the upper sintered ore is improved, and the amount of sintered return ore is reduced. The "edge effect" during sintering of ultra-thick layers is reduced, the heat supply and mineralization time of the edge layers are increased, and the strength of the edge sintered ore is improved. The air permeability of the sintering layer is improved, the ignition area is increased, the internal stress on the surface of the layer is reduced, the problem of cracking of the sintering material surface is reduced, the amount of air passing through the sintering layer is increased, and the quality of the sintered ore is improved. However, when preheating the ore, since the ore is thick when it is distributed, it makes it difficult to preheat the ore evenly, so a thick layer sintering device is needed to solve the above problems.

[0013] The partition frame designed with a conical structure can separate the mineral materials when the feeding device is conveying the mineral materials, thereby separating the thicker mineral materials.

[0014] Preferably, there are two flaps, both of which form an angle of forty-five degrees with the lower surface of the baffle, and the flaps are designed with stainless steel.

[0015] By arranging flaps between adjacent partition frames, after the ore materials are separated by the partition frames, the ore materials can be turned over by the flaps, so that the ore materials are lifted to the rear of the flaps.

[0016] Preferably, electric telescopic rods are fixedly installed at equal intervals on the top of the connecting frame, the number of the electric telescopic rods is three, and the bottoms of the three electric telescopic rods are welded and installed on the upper surface of the connecting frame.

[0017] By arranging an electric telescopic rod on the top of the connecting frame, the equipment can be installed above the feeding device through the electric telescopic rod during installation, so that the distance between the bottom of the partition frame and the upper surface of the feeding device can be adjusted through the electric telescopic rod, thereby adapting to the preheating operation of mineral materials of different thicknesses.

[0018] Preferably, the bottom of the partition plate and the bottom of the partition frame are in the same plane, and the front end of the partition plate is fixedly connected to the connecting pipe.

[0019] The bottom of the partition plate and the bottom of the partition frame are in the same plane, so that after the burner body preheats the ore, the ore can be evenly distributed through the partition plate.

[0020] Preferably, the installation height of the burner body is half of the height of the partition frame.

[0021] By arranging and installing the burner body in the middle section of the partition frame, the ore can be ignited and burned from the middle section after the ore is turned over, thereby achieving uniform preheating of the ore.

[0022] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0023] The utility model arranges a partition frame, so that during the material feeding process, the ore can be divided by the partition frame, and at the same time, the flip plate arranged between adjacent partition frames can flip the ore, and the lifted ore can fall behind the flip plate, and the ore can be burned and preheated by the burner body, so that the ore with thicker cloth can be evenly heated after flipping, thereby achieving the effect of flipping the ore with thicker cloth and preheating it evenly.

[0032] Specifically, the connecting pipe 5 passes through the front end of the upper surface of the baffle 8; wherein, holes are respectively opened in both sides of the connecting pipe 5 below the baffle 8 and connected to the burner body 2. By setting the partition frame 3, the ore can be divided by the partition frame 3 during the ore feeding process. At the same time, the flap 4 set between the adjacent partition frames 3 can flip the ore, and make the lifted ore fall behind the flap 4, and the burner body 2 can be used to burn and preheat the ore, so that the thicker ore can be evenly heated after flipping, achieving the effect of flipping the thicker ore and preheating it evenly.

[0033] Furthermore, the tops of the three baffles 8 are fixedly connected by a connecting frame 6 , and three partition plates 1 are fixedly mounted on the rear ends of the lower surfaces of the three baffles 8 .

[0034] By providing the connecting frame 6 , the adjacent baffles 8 can be fixedly installed through the connecting frame 6 , thereby achieving connection of the baffles 8 .

[0035] Furthermore, the cross section of the partition frame 3 adopts a conical structure design, and the lower surface of the partition frame 3 and the bottom of the flap 4 are in the same plane.

[0036] By using the partition frame 3 designed with a conical structure, when the feeding device is conveying the mineral materials, the mineral materials can be separated by the partition frame 3, so that thicker mineral materials can be separated.

[0037] Furthermore, there are two flaps 4, both of which form an angle of 45 degrees with the lower surface of the baffle 8, and the flaps 4 are designed with stainless steel.

[0038] By arranging the flaps 4 between adjacent partition frames 3 , after the ore materials are separated by the partition frames 3 , the ore materials can be turned over by the flaps 4 , so that the ore materials are lifted to the rear of the flaps 4 .

[0039] Furthermore, electric telescopic rods 7 are fixedly installed at equal intervals on the top of the connecting frame 6 , and there are three electric telescopic rods 7 . The bottoms of the three electric telescopic rods 7 are all welded and installed on the upper surface of the connecting frame 6 .

[0040] By arranging an electric telescopic rod 7 on the top of the connecting frame 6, the equipment can be installed above the feeding device through the electric telescopic rod 7 during installation, so that the distance between the bottom of the partition frame 3 and the upper surface of the feeding device can be adjusted through the electric telescopic rod 7, thereby adapting to the preheating operation of mineral materials of different thicknesses.

Therefore, when thicker ore is transported, the ore can be divided by the partition frame 3. At this time, the ore is divided to both sides of the partition frame 3, and the ore is turned over by the flap 4, so that the turned ore falls to the opposite side of the adjacent baffle 8, so that natural gas is injected into the burner body 2 through the connecting pipe 5, and the natural gas is ignited by the burner body 2. Therefore, after the ore is turned over by the flap 4, the ore can be preheated by the burner body 2, thereby achieving the purpose of preheating the thicker ore.
