Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sintering machine material unloading equipment, and in particular to a sintering machine material unloading device. Background Technology
[0002] In steel metallurgy, sintering machines are typically used to agglomerate fine particles of lumpy materials through granulation and / or drying processes. The initial granular material is heat-treated while being transported on a traveling grate. A traveling grate, which can be used in a dryer or granulator, is obtained via a circulating chain of trolleys (or grate boxes) moving along a track. The trolleys are filled with lumpy material and pass through a pellet burner or dryer, where they are heat-treated. The sintering process in a sintering machine involves evenly spreading a suitable blend on the trolley, igniting it, and then subjecting it to exhaust sintering. Adjustments to the machine speed and trolley material level ensure that the flue gas temperature, negative pressure, and sintering endpoint are within appropriate ranges. Due to the limitations of the blend's permeability, increasing production can lead to problems such as excessively high negative pressure in the sintering flue gas, excessively low temperature, and delayed sintering endpoint. To ensure sintering quality, the only solution is to passively reduce the sintering machine speed and the material level on the trolleys to bring these parameters within normal ranges. Therefore, it is necessary to unload the materials on the trolley.
[0003] For example, CN211177943U, published on August 4, 2020, discloses a novel material loosening device for improving the air permeability of sintering machine feed. This device relates to the technical field of sintering machine equipment and includes a carrying plate with rollers fixedly installed at its four bottom corners. A box is fixedly installed on the top of the carrying plate, and a support column is fixedly installed on the inner bottom wall of the box. A conveyor belt is fixedly installed on the support column, and a suction hood is fixedly installed inside the box. A connecting pipe is fixedly installed at the bottom of the suction hood, with both its left and right ends penetrating the inner sidewall of the box. However, the material loosening device disclosed above can only loosen the material, making it impractical. Summary of the Invention
[0004] The purpose of this invention is to provide a more practical material unloading device for sintering machines. This invention, through the unloading pipe connected to an external gas supply component, not only loosens the material but also preheats it using high-temperature steam supplied by the gas supply component, making material combustion convenient, quick, and more practical.
[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is: a sintering machine material discharge device, including a support frame connected to the crossbeam of the sintering machine, a material discharge pipe for discharging materials on the support frame, and an air supply component connected to the material discharge pipe on the support frame.
[0006] The support frame includes opposing horizontal columns, with connecting columns welded to the sintering machine beam on the opposing horizontal columns, and reinforcing columns connected to the horizontal columns on the connecting columns. The feed pipe is arranged between the opposing horizontal columns, and the opposing horizontal columns are connected by connecting beams.
[0007] The gas supply assembly includes a distribution pipe connected to a connecting column, a delivery pipe connected to a steam source, and a discharge pipe.
[0008] A mounting base is provided between the oppositely arranged horizontal columns, and the feed pipe is connected to the mounting base.
[0009] The mounting base is provided with at least two, and the feed tubes on each mounting base are arranged alternately.
[0010] The horizontal columns and connecting columns are arranged perpendicular to each other, and the reinforcing columns, horizontal columns, and connecting columns are distributed in a triangle.
[0011] The mounting base is welded to the feed tube.
[0012] The mounting base and the discharge pipe are connected by clamps.
[0013] The beneficial effects of this utility model are:
[0014] The material on the sintering machine is loosened through the material draining pipe. Steam is supplied by the gas supply component to the draining pipe and discharged, thereby heating the material and preheating it. This increases the temperature of the mixture, which helps to improve combustion efficiency and make fuller use of heat, thus reducing fuel consumption and costs. At the same time, the appropriate temperature increase is conducive to the crystallization process of minerals in the sinter, thereby improving the quality of the sinter. The draining pipe can perform both material draining and preheating, and its simple structure makes it more practical. Attached Figure Description

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0021] like Figure 1 As shown, the sintering machine material unloading device includes a support frame 1 connected to the sintering machine crossbeam 11. The support frame 1 is equipped with a material unloading pipe 2 for unloading materials. The support frame 1 is also equipped with an air supply component connected to the material unloading pipe 2. Specifically, the support frame 1 is located between the sintering machine trolley 6 and the sintering machine material feeding mechanism 7. The sintering machine material feeding mechanism 7 is used to transport materials from the sintering machine. The sintering machine material feeding mechanism 7 tilts the materials inside the sintering machine onto the sintering machine trolley 6 for movement.
[0022] In operation, the sintering machine feeding mechanism 7 transports the material inside the sintering machine to the sintering machine trolley 6. At this time, the unloading pipe 2 is buried in the material. The operation of the sintering machine trolley 6 causes the material to move, and then the unloading pipe 2 is used for loosening. While the material is being carried forward by the sintering machine trolley 6, the steam supplied by the gas supply component heats the material, thereby preheating the material and increasing the temperature of the mixture. The increase in material temperature helps to improve combustion efficiency, make more efficient use of heat, thereby reducing fuel consumption and costs. At the same time, the appropriate temperature increase is conducive to the crystallization process of minerals in the sinter, thereby improving the quality of the sinter. The unloading pipe 2 can perform both unloading and preheating work. It has a simple structure and is more practical.
[0023] The support frame 1 includes opposing horizontal columns 101, with connecting columns 102 welded to the sintering machine beam on the opposing horizontal columns 101, and reinforcing columns 103 connected to the horizontal columns 101 on the connecting columns 102. The material draining pipe 2 is arranged between the opposing horizontal columns 101, and the opposing horizontal columns 101 are connected by connecting beams 104. The support frame 1, composed of the horizontal columns 101, connecting columns 102, reinforcing columns 103 and connecting beams 104, provides stable support for the material draining pipe 2, thereby ensuring that the material draining pipe 2 stably loosens and preheats the material.

The distribution pipe 3 is equipped with a conveying pipe 4 connected to the steam source. The distribution pipe 3 is connected to the discharge pipe 2. The conveying pipe 4 delivers high-temperature steam to the distribution pipe 3, and the high-temperature steam is discharged through the discharge pipe 2, thereby realizing the heating of the material. Specifically, the conveying pipe 4 is connected to a high-pressure and high-temperature steam source. The conveying pipe 4 is set vertically, the distribution pipe 3 is set horizontally, and the connecting column 102 and the distribution pipe 3 are connected by clamps.
[0025] A mounting base 5 is provided between the oppositely arranged horizontal columns 101. The material draining pipe 2 is connected to the mounting base 5. The mounting base 5 supports the material draining pipe 2, thereby ensuring that the material draining pipe 2 can stably loosen the material and prevent the material draining pipe 2 from breaking due to material compression. In this embodiment, the mounting base 5 is a channel steel.
[0026] At least two mounting bases 5 are provided, and the material draining pipes 2 on each mounting base 5 are staggered to ensure that the material draining pipes 2 on the mounting base 5 can stably perform the work of draining and heating materials. In this embodiment, there are three mounting bases 5. The middle mounting base 5 is provided with nine material draining pipes 2, and the uppermost and lowermost mounting bases 5 are provided with eight material draining pipes 2 respectively. The material draining pipes 2 on each mounting base 5 are arranged at equal intervals.
[0027] The horizontal column 101 and the connecting column 102 are arranged perpendicularly to each other. The reinforcing column 103 is distributed in a triangle with the horizontal column 101 and the connecting column 102. In this embodiment, the horizontal column 101, the connecting column 102, the reinforcing column 103 and the connecting beam 104 are all channel steel. The horizontal column 101, the connecting column 102, the reinforcing column 103 and the connecting beam 104 are welded together. There are two horizontal columns 101, two connecting columns 102 and two reinforcing columns 103. There is one connecting beam 104. The connecting column 102 is arranged vertically, and the horizontal column 101 and the connecting beam 104 are arranged horizontally. The horizontal column 101, the reinforcing column 103 and the connecting column 102 are welded together to form a triangular frame. The two triangular frames are welded together by the connecting beam 104.
[0028] In one embodiment, the mounting base 5 is welded to the feed tube 2, thereby achieving stable installation of the feed tube 2.
[0029] In another embodiment, the mounting base 5 and the drain pipe 2 are connected by a clamp, thereby enabling convenient installation and removal of the drain pipe 2 on the mounting base 5.
