Description

Technical Field

[0001] The invention relates to the technical field of ore unloading dust reduction, in particular to a spray dust reduction device for an ore unloading pit and a construction method thereof. Background Art

[0002] During mine operations, the unloading process generates large amounts of dust. This dust not only reduces visibility in the workplace, impacting production operations and safety, but also poses a significant threat to workers' health. Long-term inhalation of dust can easily lead to occupational diseases such as pneumoconiosis, posing a serious threat to workers' lives and health. With growing awareness of environmental protection and increasingly stringent environmental regulations, mining companies need to take effective measures to control dust emissions, reduce pollution to the surrounding environment, and meet environmental standards and regulatory requirements.

[0003] Existing devices primarily use spray racks to suppress dust from ore unloading. Much of the prior art resembles a construction site dust suppression spray system. Publication number CN219539825U describes a structure comprising a base plate with support racks attached to either side of the upper end. A flow guide pipe is connected between the two support racks, with one end of the pipe connected to a booster pump. This invention changes the spraying position of the spray hood, expanding its spray range and improving spraying efficiency. However, this device still has room for improvement.

[0004] The existing device mainly fixes the spray frame on the support frame, which makes it difficult for some devices to adjust the spray frame according to the unloading position of the ore unloading car, resulting in inconvenience in accurately spraying the dust generated by unloading. At the same time, it is difficult for some devices to store the excess external water pipes into the storage box, resulting in a large amount of dust adhering to the outer walls of some water pipes due to hanging, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a spray dust reduction device for unloading pits and a construction method thereof are proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a spray dust suppression device for a mine unloading pit and a construction method thereof, so as to solve the problem that the existing devices in the prior art mentioned in the above background technology mainly fix the spray frame on the support frame, making it difficult for some devices to adjust the spray frame according to the unloading position of the mine unloading car, thereby making it inconvenient to accurately spray the dust generated by the unloading of the mine, and at the same time, it is difficult for some devices to store the redundant external water pipes into the storage box, thereby causing the outer walls of some water pipes to be contaminated with a large amount of dust due to hanging.

[0014] A construction method of a spraying dust-settling device for mine unloading pit, comprising the spraying dust-settling device for mine unloading pit, and the specific operation is as follows:
