Description

Technical Field

[0001] The present invention belongs to the technical field of automatic coal blending, and particularly relates to an automatic coal blending device based on ash monitoring. Background Art

[0002] During the process of coal processing and utilization, the ash content of coal is one of the important indicators for measuring coal quality. Excessive ash content will affect the combustion efficiency, calorific value of coal, and wear on equipment. Therefore, it is necessary to perform coal blending treatment on coal to achieve an appropriate ash content. Although the existing automatic coal blending devices based on ash monitoring have achieved automatic coal blending to a certain extent, there are still some deficiencies.

[0003] 1. The stirring efficiency of the existing devices is relatively low. During the coal blending process, different types of coal need to be fully mixed to achieve a uniform ash distribution. However, the design of the stirring mechanism of the existing devices is not reasonable enough, resulting in insufficient stirring and poor mixing effect, which affects the quality of coal blending;

[0004] 2. It is inconvenient for the existing devices to detect the ash content of coal at different feeding ports. Since the ash content of coal varies due to factors such as origin and type, it is necessary to separately detect each type of coal entering the device for precise proportioning. However, the ash detection equipment of the existing devices can usually only perform overall detection on the mixed coal and cannot separately detect the coal at different feeding ports, making it difficult to meet the requirements of precise coal blending;

[0005] 3. There are inconveniences in the existing devices for automatically controlling the blocking and opening of the feeding ports. During the coal blending process, it is necessary to precisely control the feeding amount of different coals according to the ash detection results. However, the feeding port control mechanism of the existing devices is complex to operate and has a slow response speed, unable to achieve rapid and precise blocking and opening, which affects the efficiency and accuracy of coal blending;

[0006] 4. The mobility of the existing devices is relatively poor. Since the devices are usually large in volume, complex in structure, and lack effective moving mechanisms, it is very inconvenient to install, debug, and transfer the devices between different sites, restricting their flexibility in different application scenarios.

[0007] In summary, the existing automatic coal blending devices based on ash monitoring have many problems in terms of stirring efficiency, ash detection, feeding port control, and device mobility, and urgently need to be improved and optimized to meet the requirements of the coal processing industry for efficient and precise coal blending.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The present invention realizes the efficient mixing of coal by setting up a coal mixing mechanism. The first motor drives the rotating shaft to rotate, and the stirring plates and rotating blades initially stir the coal. At the same time, the secondary stirring assembly further enhances the stirring effect, ensuring that the coal is fully mixed in the mixing housing, improving the stirring efficiency and mixing uniformity, solving the problems of insufficient stirring and poor mixing effect of the existing device, providing high-quality mixed coal for the subsequent coal blending work, and helping to improve the performance of the entire coal blending system and the utilization efficiency of coal.

[0021] 2. The present invention can accurately detect the ash content of coal at different feeding ports by setting up a coal ash monitoring mechanism. The ash monitor, through the cooperation of the height adjustment assembly and the rotating plate, detects the ash content of coal at different heights and positions, ensuring that the coal entering each feeding port can be individually detected, providing reliable data support for accurate coal blending. The setting of this mechanism makes the coal blending process more scientific and reasonable, capable of accurately proportioning according to the actual ash content of the coal, effectively improving the combustion efficiency and economic value of the coal, and at the same time reducing the wear of the equipment and environmental pollution caused by too high ash content.

The fourth motor drives the bidirectional lead screw to rotate, and the T-shaped slider drives the baffle to move along the chute, thereby accurately controlling the opening and closing of the feeding port. This mechanism is simple to operate and has a fast response speed, capable of quickly adjusting the feeding amount according to the ash detection result, improving the efficiency and accuracy of coal blending.

[0045] Specifically, the coal ash monitoring mechanism 3 further includes an annular slide rail 31 and a slider 34. The slider 34 is provided on the lower side of the turntable 35. The annular slide rail 31 corresponding to the slider 34 is provided at the upper end of the support frame 33.

The motor three 394 drives the threaded rod 396 to rotate, causing the lifting rod 391 to move up and down along the strip-shaped groove 392, thereby adjusting the height of the ash monitor 310 so that it can adapt to the coal detection requirements at different positions, and solving the problem that the existing device is inconvenient for ash detection of coal at different feed ports.

[0050] Embodiment 3

[0051] The difference between this embodiment and Embodiment 1 and Embodiment 2 lies in that the blanking port sealing mechanism 9 includes a mounting seat two 91, a motor four 92, a bidirectional lead screw one 93, a baffle 94, a T-shaped slider one 95, a mounting seat one 96, a transmission component 97, and a chute 98. A mounting seat one 96 is provided on one side of the lower end of the mixing housing 1. A mounting seat two 91 is provided on the other side of the lower end of the mixing housing 1.

The operation is simple, the response speed is fast, and the efficiency and accuracy of coal blending are improved.

[0053] Specifically, the transmission component 97 includes a T-shaped slider two 971, a synchronous pulley one 972, a synchronous belt 973, a bidirectional lead screw two 974, and a synchronous pulley two 975.

A bidirectional lead screw two 974 is arranged on the side of the synchronous pulley two 975. Two groups of T-shaped sliders two 971 are symmetrically arranged on the surface of the bidirectional lead screw two 974. The T-shaped slider two 971 is fixed on the upper end of the baffle 94 on the other side.

[0054] By adopting the above technical solution, through the transmission of the synchronous belt 973 between the synchronous pulley one 972 and the synchronous pulley two 975, the bidirectional lead screw one 93 and the bidirectional lead screw two 974 rotate synchronously, driving the two groups of T-shaped sliders one 95 and T-shaped sliders two 971 to move, thereby realizing the stable movement of the baffle 94 and further improving the reliability of the blocking and opening of the blanking port.

[0055] When this embodiment is in use, when it is necessary to open the blanking port, the controller 5 controls the motor four 92 to start. The motor four 92 drives the bidirectional lead screw one 93 to rotate, and drives the baffle 94 to move along the chute 98 to both sides through the T-shaped slider one 95, thereby opening the blanking port. When it is necessary to block the blanking port, the motor four 92 rotates in the reverse direction, driving the baffle 94 to move towards the middle to realize the blocking of the blanking port. The whole process has a high degree of automation and a fast response speed, can accurately control the blanking amount according to the ash detection result, and improves the efficiency and accuracy of coal blending.

[0056] Embodiment 4

[0057] The difference between this embodiment and the above embodiment is that the moving mechanism 8 includes a pulley 81, a universal wheel 82, a slide rail 83, a lifting plate 84, a support seat 85, and a driving component 86.

The slide rail 83 corresponding to the pulley 81 is opened on the inner wall of the bottom box 11. The universal wheel 82 is arranged at the corner of the lower end of the bottom box 11.

[0058] By adopting the above technical solution, the automatic blocking and opening of the blanking port are realized. The motor four 92 drives the bidirectional lead screw one 93 to rotate, and the T-shaped slider one 95 drives the baffle 94 to move along the chute 98, so as to realize the blocking and opening of the blanking port. The operation is simple, the response speed is fast, and the efficiency and accuracy of coal blending are improved.

[0059] Specifically, the driving assembly 86 includes a motor five 861, a rotating rod two 862, a worm 863, a worm gear 864 and a screw rod 865. The motor five 861 is arranged on the side of the bottom box 11. The output end of the motor five 861 is provided with a rotating rod two 862. The other end of the rotating rod two 862 is provided with a worm 863. The side of the worm 863 is meshed with a worm gear 864. The screw rod 865 is fixedly penetrated inside the worm gear 864. The lifting plate 84 is in threaded engagement with the screw rod 865.

[0060] By adopting the above technical solution, the synchronous pulley one 972 and the synchronous pulley two 975 are driven by the synchronous belt 973, so that the bidirectional lead screw one 93 and the bidirectional lead screw two 974 rotate synchronously, driving the two groups of T-shaped sliders one 95 and T-shaped sliders two 971 to move, thereby realizing the stable movement of the baffle 94 and further improving the reliability of the blocking and opening of the blanking port.

[0061] When this embodiment is in use, when the device needs to be moved, the controller 5 controls the motor five 861 to start. The motor five 861 drives the rotating rod two 862 to rotate, driving the worm 863 to rotate. The worm 863 is in meshing transmission with the worm gear 864, so that the screw rod 865 rotates. Since the lifting plate 84 is in threaded engagement with the screw rod 865, the rotation of the screw rod 865 will drive the lifting plate 84 to move up and down along the slide rail 83. When the lifting plate 84 descends, the support seat 85 contacts the ground and the universal wheel 82 leaves the ground, and the device is fixed on the ground. When the lifting plate 84 ascends, the universal wheel 82 contacts the ground, and the device can be conveniently moved to the required position. This design not only improves the flexibility of the device, but also ensures the stability of the device during operation.

[0062] Working principle and usage process of the present invention: When the present invention is in use, first, the coal mixing mechanism 4 is started through the controller 5.

During the coal mixing process, the coal ash monitoring mechanism 3 is started. The second motor 32 drives the turntable 35 to rotate, driving the rotating plate 38 to move through the first rotating rod 36 and the inclined rod 37, enabling the ash monitor 310 to detect the ash content of the coal at different positions. At the same time, the third motor 394 in the height adjustment assembly 39 drives the threaded rod 396 to rotate, driving the lifting rod 391 to move up and down along the strip-shaped groove 392 through thread engagement, adjusting the height of the ash monitor 310 to achieve ash content detection of the coal at different heights. According to the ash content monitoring results, the controller 5 controls the fourth motor 92 in the blanking port blocking mechanism 9 to start, driving the bidirectional lead screw one 93 to rotate, driving the baffle 94 to move along the sliding groove 98 through the T-shaped slider one 95, realizing the blocking or opening of the blanking port to ensure precise control of the blanking amount.
