Problems solved by technology
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 coke produced by the dry quenching process often has a water content lower than 1%, so the dust concentration at each dust point is very high, especially when the coke screen is loaded by train, and the distance from the outlet of the material gate to the bottom of the transport car is about 6.25 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 solutions of the present invention will be described in detail below with reference to the accompanying drawings.
[0030] like figure 1 , figure 2 , image 3 As shown in the figure, a dust suppression telescopic loading and unloading device for bulk materials is composed of three parts: a telescopic hopper, a fan dust removal device, and a micron-level dry fog dust suppression device; the telescopic hopper is a retractable 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 the hopper can fall in sequence. Gate 6, after the hopper is full, slowly and synchronously open 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 secondary hopper 3 is set outside the small hopper 2 and can be lifted and lowered relative ...

The invention discloses a dust suppression telescopic loading and unloading device for bulk materials, which consists of three parts: a telescopic hopper, a fan dust removal device, and a micron-level dry fog dust suppression device; the telescopic hopper is a telescopic structure with a gate , including 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 After the hopper is fully filled, the gate is slowly and synchronously opened for loading. The invention also discloses a dust suppression telescopic loading and unloading method for bulk materials. The telescopic hopper of the present invention reduces the actual falling height of the material, decelerates it, reduces the airflow pressure generated by the impact, reduces dust, prevents the material from impacting on the compartment and is crushed, loads the vehicle quantitatively, and improves efficiency. At the same time, the dust removal fan and the micron-level dry fog dust suppression device are gradually turned on during the loading process, which further suppresses the dust.
Description
technical field [0001] The invention relates to a novel loading device, in particular to a dust-suppressing telescopic loading and unloading method for bulk materials. Background technique [0002] Bulk loading trucks are widely used in metallurgy, coking, mining and many other fields, but their working environment is generally dusty and harsh. Dust pollution is an important factor causing acid rain, photochemical smog and air visibility decline in urban atmosphere, and it seriously endangers human health, leading to respiratory diseases, cardiovascular diseases and even cancer. With the increase of bulk cargo volume and stockpiling year by year, the dust pollution caused by the loading and unloading of dry bulk materials, especially cement, coke, ore, coal, iron ore powder and other heavy-duty cargoes to the surrounding areas of the port, has caused government related issues. The high attention of the department and the serious concern of the society also have a certain im...
