Description

Technical Field

[0001] This utility model relates to the field of dust suppression technology for conveyors, specifically a dust suppression device for belt conveyors. Background Technology

[0002] Belt conveyors are widely used in industries such as mining, ports, and power plants, primarily for the continuous transport of materials. However, during the operation of belt conveyors, the loading, unloading, conveying, and belt movement all generate a large amount of dust. This dust not only seriously pollutes the working environment and harms the health of operators, easily causing occupational diseases such as respiratory illnesses, but it can also enter the interior of mechanical equipment, accelerating wear and tear, reducing equipment lifespan and operating efficiency. Therefore, dust suppression spraying is necessary for conveyors.

[0003] In the prior art, utility model patent CN202323472327.2 discloses a spraying device for a conveyor, including a bracket. A motor is fixedly installed on the surface of the bracket, and a conveyor belt is installed at the output end of the motor. A mounting bracket is fixedly installed at the top of the bracket, and a support plate is fixedly installed at the bottom of the bracket. This design achieves a better usage method. Before use, the sliding plate is pinched by the pinch groove and pulled upwards, allowing the sliding plate to slide upwards through the limiting groove inside the baffle. When the sliding plate slides to the desired position, the pull block is pinched to align the locking rod with the fixing groove and push it inwards, so that the locking rod and the soft pad slide completely into the fixing groove. At this time, the soft pad can firmly lock the locking rod inside the fixing groove, and the locking rod firmly fixes the sliding plate in the current position. This avoids the situation where, due to the lack of a limiting structure, there is an angle during use, causing coal to roll off the output end, leaving a large amount of coal around the conveyor that requires workers to pick up.

[0004] The aforementioned patent provides a spray dust suppression device for conveyors. However, this spray dust suppression device is directly fixed on the conveyor. Different sizes of spray dust suppression devices are required for different sizes of conveyors, resulting in poor adaptability. Furthermore, when the spray dust suppression device needs maintenance, the conveyor must be stopped before maintenance can be carried out. Utility Model Content

Moreover, the first atomizing nozzle 909 and the second atomizing nozzle 910 on the sliding spray assembly 901 and the fixed spray assembly 902 have opposite tilting directions, so whether they overlap or unfold, they will fully cover the expanded range. Thus, dust suppression spraying can be achieved for conveyors of different sizes.

[0034] In summary, by setting up a sliding and expandable first horizontal plate 2 and second horizontal plate 4, this utility model can increase the distance between the first side plate 1 and the second side plate 3, thereby allowing the distance between the first side plate 1 and the second side plate 3 to be adjusted independently for conveyors of different sizes. This makes it convenient for the spray dust suppression equipment to be installed on any type of conveyor, with strong applicability. Moreover, when the spray dust suppression equipment needs maintenance, it can be directly pushed away for maintenance. By dividing the spray device into a sliding spray component 901 and a fixed spray component 902, the spray range can be expanded automatically by following the sliding of the first horizontal plate 2 and the second horizontal plate 4.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
