[0002] The quality of sintered ore has an important impact on the stability and smooth operation of the blast furnace. During the smelting process, the sintered ore is required to have good strength and metallurgical performance indicators. Therefore, the sintered ore is sampled and tested every two hours. The smelting parameters and processes of the blast furnace are adjusted according to the test data to ensure the stability of the furnace condition and avoid the influence of the output, quality, energy consumption and other indicators of blast furnace ironmaking due to the fluctuation of sintered ore quality. The stability of the sintered ore sampling equipment is particularly important.

[0003] At present, the sampling and sample preparation of sintered ore are all done manually by on-the-job personnel, and then sent to relevant laboratories for testing. There are many problems in the whole sampling process: ① Manual sampling and startup are required when the belt conveyor is running, which poses a safety hazard; ② When the sampling belt runs to the discharge port, the sampling volume is not easy to control. The actual sampling volume required is only about 10kg, and the excess needs to be sent back to the belt. Sampling is done every two hours, which results in high workload and work intensity.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In this embodiment, Figure 1-4As shown, a simple sintered ore sampling device comprises: a sampling hopper 10 and a rotating shaft 20. The top of the sampling hopper 10 is provided with a receiving opening 11, the bottom of the sampling hopper 10 is provided with a slope 12, the bottom of the slope 12 is provided with a discharge opening 13, and the sampling hopper 10 is installed on the rotating shaft 20; when the sampling hopper 10 is rotated to the first position, the receiving opening 11 is connected to the discharge end of the conveyor belt 30; when the sampling hopper 10 is rotated to the second position, the receiving opening 11 avoids the discharge end of the conveyor belt 30. The sampling hopper 10 can rotate in both directions by means of the rotating shaft 20, such as Figure 2 , 4 As indicated by the arrow. When sampling is required, the sampling hopper 10 is rotated to the first position, and the material falls from the output end of the conveyor belt 30, passes through the receiving opening 11 and falls into the sampling hopper 10, slides down through the slope 12, and is then discharged through the discharge opening 13; when enough samples are taken, the sampling hopper 10 is rotated to the second position without affecting the normal unloading operation. In this embodiment, the simple sintered ore sampling device also includes a rotating drive device 60, and the drive device 60 is connected to the rotating shaft 20. Sampling is performed by driving the rotating shaft 20 to rotate by the drive device 60. The sampling personnel do not need to directly contact the space where the conveyor belt 30 runs, thereby avoiding accidental injuries.

[0030] The sampling and receiving hopper 10 is basically a right triangle, with one right-angled side of the right triangle being horizontal and the other right-angled side being vertical. The sampling and receiving opening 11 is located on the horizontal right-angled side of the right triangle, the hypotenuse of the right triangle forms a slope 12, and the vertical right-angled side of the right triangle is basically parallel to the rotating shaft 20.

[0031] The rotating shaft 20 includes an upper semi-shaft 21 and a lower semi-shaft 22. The top of the sampling hopper 10 is mounted on the bottom of the upper semi-shaft 21. Specifically, the upper semi-shaft 21 is connected to the horizontal right-angled side of the right triangle through a flange; the bottom of the sampling hopper 10 is mounted on the top of the lower semi-shaft 22. Specifically, the lower semi-shaft 22 is connected to the sampling hopper 10 through a flange. With such a design, the sampling hopper 10 is basically bilaterally symmetrical relative to the rotating shaft 20. The sampling hopper 10 is jointly supported by the upper semi-shaft 21 and the lower semi-shaft 22, and the force is stable, which can prevent overturning caused by the impact of falling materials.

[0032] The side wall of the sampling hopper 10 is provided with an observation window 14. The material receiving opening 11 and the observation window 14 are located on both sides of the rotating shaft 20, so that when the sampling hopper 10 is rotated to the first position, the material receiving opening 11 is rotated to the bottom of the discharge end of the conveyor belt 30, and the observation window 14 faces outward, so that it is convenient to observe the falling material through the observation window 14. In this embodiment, the observation window 14 is close to the top of the sampling hopper 10 to prevent the material from scattering from the observation window 14.

[0033] A discharge chute 15 is provided at the material receiving opening 11. The discharge chute 15 is tilted, the upper end of the discharge chute 15 is connected to the lower edge of the material receiving opening 11, and the lower end of the discharge chute 15 is tilted downward. The discharge opening 13 is located at a vertical right angle, and the discharge opening 13 and the material receiving opening 11 are located on both sides of the rotating shaft 20. The material receiving opening 11 and the discharge chute 15 are located on both sides of the rotating shaft 20.

[0034] The simple sintered ore sampling device also includes a guide trough 40, which is tilted, and the upper end of the guide trough 40 is connected to the discharge opening 13. Since the edge of the discharge opening 13 is provided with a discharge trough 15, the upper end of the guide trough 40 is supported below the discharge trough 15, and the sampled material is guided to slide to the guide trough 40 through the discharge trough 15. When the sampling hopper 10 rotates to the first position, the material slides from the discharge opening 13, passes through the discharge trough 15 and falls into the guide trough 40. The material is guided to slide to the designated position by the tilt of the guide trough 40, and the sampling personnel do not need to get close to the conveyor belt 30, thereby ensuring safety. The width of the opening at the upper end of the material guide trough 40 is greater than the width of the discharge opening 13 and greater than the width of the discharge trough 15. When the sampling hopper 10 rotates, the discharge opening 13 or the discharge trough 15 swings in the opening at the upper end of the material guide trough 40. The wider upper opening of the material guide trough 40 can receive the material falling from the discharge opening 13 or the discharge trough 15 during rotation.

[0035] The simple sintered ore sampling device further includes a sample conveying belt 50, and the lower end of the material guide trough 40 is connected to the sample conveying belt 50. The material guide trough 40 centrally guides the materials into the sample conveying belt 50. In this embodiment, the sample conveying belt 50 is used to convey the sampled materials, and the materials sliding down from the material guide trough 40 fall onto the sample conveying belt 50, and the sample conveying belt 50 conveys the materials to the designated location, and there is no need for personnel to approach the sampling point, thereby improving production safety.

[0036] The present invention is described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
