TECHNICAL FIELD
[0001] The utility model relates to bulk cargo loading and unloading dust suppression technical field especially is related to a bulk cargo loading and unloading dust suppression equipment. BACKGROUND
[0002] Bulk cargo such as imported soybeans and corn will generate a large amount of dust during loading and unloading, especially since these grains often contain talc powder and other fine particles. These talc powder particles have strong water absorption and fine particle size characteristics. Not only does this type of dust pollute the operating area and port environment, but it also spreads through the air, affecting the air quality of the surrounding area and even possibly harming the health of nearby residents. In addition, long-term inhalation of fine particles poses a significant threat to the health of terminal operators, potentially causing respiratory diseases, lung inflammation, and even occupational diseases.
[0003] In order to effectively control and reduce the dust generated during the loading and unloading of bulk cargo, especially when loading and unloading bulk cargo such as imported soybeans and corn, dust suppression equipment has become an important tool for assisting operations. However, the existing bulk cargo loading and unloading dust suppression equipment has many shortcomings. First, the equipment cannot provide effective multiple buffering for bulk cargo such as soybeans and corn released from a high place, resulting in a large impact force when they fall, which easily generates dust. And these bulk cargo often contain talc powder and other fine particles, which further exacerbate the formation of dust during the falling process. Second, the existing equipment has poor dust suppression effect on the dust generated during the loading and unloading of bulk cargo when facing these dust problems, resulting in dust that is not timely suppressed and captured. In the process of loading and unloading bulk cargo, fine particles such as talc powder are affected by wind, mechanical movement, and other factors, and are excited into the air, forming high-concentration suspended particles, which further exacerbates dust pollution, causing serious health risks and work obstacles to the environment and operators. Therefore, it is particularly urgent to develop a new dust suppression equipment with multiple buffering function and effective dust suppression.
[0004] Based on this, we propose a bulk cargo loading and unloading dust suppression equipment to solve the above-mentioned problems. SUMMARY
