Description

Technical Field

[0001] This utility model relates to the field of coal conveying cleaning technology, and more specifically to an adjustable coal conveying cleaning and dust suppression device. Background Technology

[0002] Coal conveying is a crucial link in the coal mining, transportation, and storage process. However, traditional coal conveying systems often face numerous challenges during operation. For example, coal transportation, especially the transfer from the coal drop point to the conveyor belt, easily generates a large amount of dust. This dust not only pollutes the environment and endangers worker health but can also cause safety accidents. Existing dust suppression devices are prone to belt misalignment when operating at high speeds or under uneven loads. Belt misalignment not only leads to coal spillage, further exacerbating dust pollution and material loss, but can also cause wear and tear on equipment, shortening its service life. Traditional belt alignment devices are typically inconvenient to adjust, complex to maintain, and have limited correction effectiveness. When the belt deviates, the anti-overflow skirts on both sides may not fit effectively, thus reducing the anti-overflow and dust suppression effects.

[0003] Therefore, it is necessary to propose an adjustable coal conveying cleaning and dust suppression device to solve the above problems. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 4An adjustable coal conveying cleaning and dust suppression device includes a tail box device 5, a coal drop pipe 9, a circulation pipe 4, and a pressure relief dust suppression chamber 3, sequentially arranged in the direction of travel of the coal conveying cleaning line. The tail box device 5 is usually located at the end of the coal conveying cleaning line and is used to collect and guide coal. The pressure relief dust suppression chamber 3 and the circulation pipe 4 form a dust collection and treatment system. When dust is generated on the coal conveying line, the pressure relief dust suppression chamber 3 can draw in the dust through negative pressure or airflow guidance, and treat it through the circulation pipe 4, such as through filtration and settling, ultimately achieving the emission of clean air and further reducing environmental pollution. Multiple adjustable dust curtains 1 are also installed on the coal conveying cleaning line, which can be adjusted in height or angle according to actual needs to adapt to different coal conveying volumes, coal particle sizes, or wind speed conditions, thereby more effectively blocking dust overflow and improving the dust suppression effect. Figure 1 As shown, the adjustable dust curtain 1 is installed in multiple locations, such as two at each end of the coal conveying cleaning line and one at each end of the pressure relief dust suppression chamber 3, but it is not limited to the present application. Figure 1 The layout shown in the application, such as the coal conveyor belt dust reduction device disclosed in application number 202221727240.8, discloses a similar layout of a coal conveying cleaning line, which can be used as a reference for the prior art. For the setting of the adjustable dust curtain 1, electric lifting or hydraulic lifting can be used to achieve the setting. The prior art is relatively mature and will not be described in detail hereafter. The difference is that this device is equipped with an adjustable conveyor belt mechanism in the coal conveying cleaning line for conveying coal block movement, ensuring the stability of coal during the conveying process and reducing dust generation. The lower end outlet of the coal drop pipe 9 is inclined towards the direction of travel of the coal conveying cleaning line so that when the coal falls from the coal drop pipe 9 onto the conveyor belt, it can smoothly transition along the direction of travel, reducing the impact force of the coal and thus reducing the amount of dust generated.

[0019] Specifically, the conveyor belt mechanism includes a guide chute body 2, an adjustable alignment device 8 located at the bottom of the guide chute body 2, a conveyor belt that fits against the adjustable alignment device 8, and a clamp 6 and a Y-shaped anti-overflow skirt 7 located on the guide chute body 2 above the adjustable alignment device 8. The lower end of the Y-shaped anti-overflow skirt 7 fits against the upper end of the adjustable alignment device 8, allowing the Y-shaped anti-overflow skirt 7 to fit tightly with the conveyor belt. Even if the conveyor belt deviates slightly, it can be adjusted by the adjustable alignment device 8, ensuring that the anti-overflow skirt 7 always maintains its effective anti-overflow and dust suppression functions. The clamp 6 is used to fix the Y-shaped anti-overflow skirt 7, ensuring its stability and reliability.

[0020] Specifically, such as Figure 2 and Figure 3 As shown, the adjustable centering device 8 of this application is installed... Figure 3The adjustable counterweight device shown is positioned such that the adjustable centering device 8 includes a connecting fixed rod 81, an adjusting rod 82 inserted into both ends of the connecting fixed rod 81, a fixed seat 83 fixedly connected to the end of the adjusting rod 82 away from the fixed rod 81, and a roller assembly 84 disposed on the upper end of the fixed rod 81. The fixed rod 81 and the adjusting rod 82 have insertion holes at both ends for inserting bolts or connectors to fix the fixed rod 81 and the adjusting rod 82 relative to each other. The conveyor belt is attached to the top of the roller assembly 84, and the fixed seat 83 is fixedly connected to the inner side of the guide trough body 2.

[0021] In practice, you can refer to Figure 2 As shown by the arrow, the adjustment rod 82 can be used to adjust the conveyor belt alignment when needed. The adjustment rod 82 is inserted into both ends of the connecting fixed rod 81. By extending or retracting, it changes the horizontal position of the roller assembly 84, thereby achieving conveyor belt alignment. The roller assembly 84 contacts the conveyor belt, supporting and guiding its movement. The fixed base 83 provides stable support, ensuring the reliability of the entire adjustable alignment device 8. This improves the operational stability of the conveyor belt, effectively preventing deviation and reducing material spillage and dust generation.

[0022] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. The patent protection scope of this utility model is determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of this utility model should also be included within the protection scope of this utility model.
