And these working methods are all open-type loading, with a large amount of dust, serious pollution to the atmospheric environment, and great potential safety hazards.
[0004] Taking the coking plant as an example, the water content in coke produced by the CDQ process is often lower than 1%, so the dust concentration at each dust point is very high, especially when the coke screen is loaded by train. m, the train continues to move back and forth during loading, and the staff controls the swing angle of the chute and the amount of material sluice to load the vehicle through visual inspection, and the operation is complicated
The material leaves the gate, passes through the loading chute, and quickly slides down to the bottom of the carriage. The coke material flow rate is large, the drop is high, and it belongs to open charging, resulting in a large amount of dust. If the smoke generated is not effectively controlled, it will cause serious environmental problems. pollution, large
Most companies use fans to remove dust, but the effect is not ideal
Some enterprises put the cart before the horse and reduce dust pollution by producing wet coke quenching, but they also cause air pollution of toxic and harmful gases such as cyanide, hydrogen sulfide, and ammonia.

Embodiment Construction
[0029] The technical scheme of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0030] Such as figure 1 , figure 2 , image 3 As shown, a dust-suppressing telescopic loading and unloading device for bulk materials is composed of three parts: a telescopic hopper, a fan dust removal device, and a micron-scale dry fog dust suppression device; the telescopic hopper is a telescopic structure with a gate, It includes a lifting device, a telescopic hopper body, and a gate opening and closing mechanism; the telescopic hopper body is composed of multi-stage hoppers, and each stage of hopper can fall in turn, and the gate opening and closing mechanism is a split type installed on the most end large hopper 4 Gate 6, after the hopper is fully filled, slowly and synchronously opens for loading.
[0031] The telescopic hopper is divided into three stages, namely a small hopper 2, a secondary hopper 3, and a large hopper 4. The seco...

The invention discloses a dust suppression retractable loading and unloading device for bulk materials. The dust suppression retractable loading and unloading device for the bulk materials is composed of three parts including a retractable hopper, a fan dust extraction device and a micron-level dry mist dust suppression device. The retractable hopper is a retractable structure with a gate and comprises a lifting device, a retractable hopper body and a gate opening and closing mechanism. The retractable hopper body is composed of a plurality of levels of hoppers. Each level of hopper can descends sequentially. The gate opening and closing mechanism is an opposite-opening gate installed on the large hopper at the rearmost end. After all the hoppers are loaded fully, all the hoppers are slowly opened at the same time for truck loading. The invention further discloses a dust suppression retractable loading and unloading device for the bulk materials. The retractable hopper reduces the actual falling height of the materials, slows down the materials, reduces the airflow pressure produced through collision and raised dust and prevents the materials from being broken when the materials impact a compartment, ration loading is achieved, and the efficiency is improved. Meanwhile, a dust removal fan and the micron-level dry mist dust suppression device are gradually turned on in the loading process, and a further suppression effect is achieved for the raised dust.
Description
technical field [0001] The invention relates to a novel vehicle loading device, in particular to a dust suppression telescopic loading and unloading device and method for bulk materials. Background technique [0002] Bulk material loading is widely used in many fields such as metallurgy, coking, mining, etc., but its working environment is generally dusty and harsh. Dust pollution is an important factor that causes urban atmospheric acid rain, photochemical smog and decreased air visibility, and it seriously endangers human health, leading to respiratory diseases, cardiovascular diseases and even cancer. With the increasing volume of bulk cargo and stockpiles year by year, the loading and unloading of dry bulk materials, especially cement, coke, ore, coal, iron ore powder and other heavy dusty cargoes, has caused dust pollution to the surrounding areas of the port. The high attention of the department and the serious concern of the society also have a certain impact on the ...
