TECHNICAL FIELD

[0001] The present application relates to the technical field of chemical safety, in particular to a dust falling mechanism for chemical safety. BACKGROUND

[0002] Chemical production refers to a process of using chemical reactions or material transformation to produce desired chemical products through a series of process operations. It covers a wide range of fields, including petroleum chemical industry, organic synthesis, inorganic chemical industry, fine chemical industry, etc. During chemical production, environmental protection regulations and safety production standards must be strictly followed to ensure the safety of the production process and the sustainability of the environment. Dust and particulate matter are generated during chemical production. In order to reduce the impact on the environment and human health, dust falling devices are usually used for dust falling. For example, the dust falling device for safe production of chemicals disclosed in CN223096437U, by arranging two first motors inside the dust falling box, arranging a dust suction pipe inside the dust falling box, arranging a second motor inside the dust suction pipe, arranging a fan at the output end of the second motor, and arranging a filter screen below the fan, the dust on the floor of the chemical plant can be cleaned, and the cleaning area is large and the cleaning intensity is high. However, its efficiency is not high during use, and it is limited by the motor and water pump during use, specifically: The height of the atomizing nozzle in the above-mentioned prior art is constant, which leads to constant dust falling height. In addition, the spraying range is fixed, which leads to insufficient dust falling efficiency. Furthermore, in the prior art, the use of a motor and a water pump for driving results in the need to connect to a power source during use, which is limited by the length of the power cord and uses electrical energy, making it impossible to use in some locations where it is inconvenient to connect to a power source.

During the reciprocating movement of the mounting plate, the steel wire rope, rope reel, and torsion spring enable the mounting shaft to rotate reciprocally, thereby allowing the nozzles mounted on it to swing back and forth. The reciprocating movement of the mounting plate changes the spraying height of the nozzles, and the swinging of the nozzles changes the spraying range, helping to achieve more efficient all-around spraying. This avoids the problem of fixed nozzle positions in the past, where the nozzles could only spray towards the same location, resulting in ineffective dust suppression in areas close to the nozzles. This improves the efficiency of dust suppression. Attached Figure Description
