[0001] The utility model belongs to the technical field of tunnel furnaces, in particular to a tunnel furnace sintering line. Background Art

[0002] Sintering line usually refers to a part of sintering machinery and equipment in the metallurgical industry. Sintering is a process of heating powdered raw materials to a high temperature close to the melting point so that the raw material particles combine together to form a block-like substance. During the sintering process, the raw materials are transported to the inside of the tunnel furnace through the sintering line. The sintering line is usually composed of equipment such as conveyor belts and conveyors, which are used to transport raw materials from storage warehouses or pretreatment equipment to the sintering machine for sintering processing. The design and operation of the sintering line are crucial to the stability and efficiency of the sintering process, because the uniform transportation and control of raw materials directly affect the quality and production efficiency of sintered blocks. Through the reasonable design and management of the sintering line, the precise supply of raw materials can be achieved, the continuity and stability of the sintering process can be ensured, and the quality and production efficiency of the sintered products can be improved.

[0003] However, the above device still has the following problems during implementation:

[0004] The existing technology makes the uniform delivery and control of raw materials directly affect the quality and production efficiency of sintered blocks. However, the existing tunnel furnace sintering line does not have a component for accurately unloading raw materials. If the raw materials are directly transported to the sintering line using a spiral feeder, the raw materials will move due to the downward impact force, and the raw materials will splash everywhere on the ground and cause waste. Therefore, a tunnel furnace sintering line is specially proposed to solve the above problems. Utility Model Content

[0022] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0023] like Figures 1 to 4As shown, a tunnel furnace sintering line provided by an embodiment of the utility model comprises a machine body 1 and a material discharge assembly 2, wherein the material discharge assembly 2 is arranged on the top of the machine body 1;

[0024] A material unloading assembly 2 for unloading sintering raw materials, the material unloading assembly 2 comprising a material unloading frame 21, the material unloading frame 21 is movably connected to the top of the machine body 1, the left and right sides of the inner cavity of the material unloading frame 21 are movably connected with material guide plates 22, and the material of the material guide plates 22 is transparent acrylic, the rear side of the material guide plates 22 is in contact with the machine body 1, and the left and right sides of the front side of the material unloading frame 21 are provided with moving holes 23;

[0025] The control component 3 is used to control the blanking component 2 , and the control component 3 is arranged on the front side of the blanking frame 21 .

[0026] refer to Figure 3 A travel hole 4 is provided on the left and right sides of the material discharge frame 21 , and a protective plate 5 is slidably connected to the inner cavity of the travel hole 4 , and the opposite sides of the two protective plates 5 are fixedly connected to the material guide plate 22 .

[0027] The above solution is adopted: by setting the travel hole 4 and the protective plate 5, when the guide plate 22 is squeezed and moved, the travel hole 4 and the protective plate 5 can control the moving position of the guide plate 22, and the protective plate 5 can prevent the raw material from moving into the unloading frame 21.

[0028] refer to Figure 2 The bottom of the blanking frame 21 is fixedly connected with a protective frame 6, the bottom of the protective frame 6 is fixedly connected to the top of the body 1, and viewing holes 7 are opened on the left and right sides of the protective frame 6.

[0029] The above solution is adopted: by providing the protection frame 6 and the viewing hole 7, when the raw materials are being discharged, the protection frame 6 can protect the front side, because the material of the guide plate 22 is transparent acrylic, the discharge situation in the guide plate 22 can be observed through the viewing hole 7.

[0030] refer to Figure 3 The opposite sides of the two guide plates 22 are fixedly connected with tension springs 8, and the side of the tension springs 8 close to the blanking frame 21 is fixedly connected to the blanking frame 21, and there are multiple tension springs 8.

[0031] The above solution is adopted: by setting the tension spring 8, when the extrusion wheel 10 is no longer in contact with the guide plate 22, the tension of the tension spring 8 will drive the guide plate 22 back to its original position, so there is no need to manually reset the guide plate 22.

[0032] refer to Figure 3The left and right sides of the inner cavity of the unloading frame 21 are movably connected with a rising plate 9, the top of the rising plate 9 is movably connected with an extrusion wheel 10, the top of the extrusion wheel 10 is in contact with the guide plate 22, and the front and rear sides of the extrusion wheel 10 are rotatably connected to the rising plate 9 through bearings.

[0033] The above scheme is adopted: by setting the rising plate 9 and the extrusion wheel 10, when it is necessary to move the two guide plates 22 at the same time, the rising plate 9 will drive the two extrusion wheels 10 to squeeze the inclined surface of the guide plate 22, and the guide plates 22 will be squeezed to move closer to each other and pull the tension spring 8.

[0034] refer to Figure 2 and Figure 3 The inner cavity of the movable hole 23 is movably connected with a U-shaped plate 11 , the rear side of the U-shaped plate 11 is fixedly connected with the rising plate 9 , and a threaded hole 12 is opened on the top of the U-shaped plate 11 .

[0035] The above solution is adopted: by setting the U-shaped plate 11 and the threaded hole 12, when the rising plate 9 moves, it will drive the U-shaped plate 11 to move in the moving hole 23. Because of the moving hole 23, when the screw rod 32 rotates, the U-shaped plate 11 will not rotate.

[0036] refer to Figure 3 The control assembly 3 includes a fixed plate 31, the rear side of the fixed plate 31 is fixedly connected to the blanking frame 21, the bottom of the fixed plate 31 is rotatably connected to a screw rod 32 through a bearing seat, and the bottom of the screw rod 32 passes through the threaded hole 12 and is fixedly connected to a grip plate 33.

[0037] The above scheme is adopted: by setting the control component 3, when it is necessary to control the U-shaped plate 11 to rise, hold the grip plate 33 tightly and rotate it. The rotation of the grip plate 33 will drive the screw 32 to rotate. The rotation of the screw 32 around the bearing seat will drive the U-shaped plate 11 threadedly connected thereto to rise.

[0038] The working principle of the utility model is as follows: during use, when it is necessary to unload the tunnel furnace sintering line, the position of the guide plate 22 can be adjusted according to different raw materials. At this time, hold the grip plate 33 tightly and rotate it. The rotation of the grip plate 33 will drive the screw 32 to rotate. The rotation of the screw 32 around the bearing seat will drive the U-shaped plate 11 threadedly connected thereto to rise. The rise of the U-shaped plate 11 will drive the two rising plates 9 to rise. The rise of the rising plate 9 will drive the two extrusion wheels 10 to squeeze the inclined surface of the guide plate 22. The guide plates 22 will be squeezed and will approach each other and pull the tension spring 8. The movement of the guide plate 22 will drive the protective plate 5 to move in the stroke hole 4. After the guide plate 22 is adjusted to a suitable position, the raw materials to be sintered are poured from the top of the guide plate 22. At this time, the guide plate 22 can accurately transport the raw materials to the tunnel furnace sintering line. When unloading, the protective frame 6 can prevent the raw materials from leaking from the front side of the protective frame 6.

[0039] To sum up: the tunnel furnace sintering line, by setting the unloading component 2, the unloading frame 21, the guide plate 22, the moving hole 23 and the control component 3 for coordinated use, when the guide plate 22 is adjusted to a suitable position, the raw materials to be sintered are poured in from the top of the guide plate 22, and then the guide plate 22 can accurately transport the raw materials to the tunnel furnace sintering line. When unloading, the protective frame 6 can prevent the raw materials from leaking from the front side of the protective frame 6, which solves the problem that the tunnel furnace sintering line does not have a component for accurately unloading the raw materials. If the raw materials are directly transported to the sintering line using a spiral feeder, the raw materials will move due to the downward impact force, and the raw materials will splash everywhere on the ground and cause waste.
