Description

TECHNICAL FIELD

[0001] The utility model relates to dust extraction equipment technical field, concretely relates to a detachable dust extraction device for coke loading. BACKGROUND

[0002] Coke is one of the final products of coal coking, and is an important industrial raw material, widely used in metallurgy, chemical industry, chemical fertilizer and many other fields. Generally, it is transported to the coke storage for storage, so when the coke is transported and loaded, the coke in the coke storage needs to be transported to the transport vehicle by the conveying device to complete the loading operation. The discharge port of the coke storage is generally designed as a square opening, and the discharge port is designed relatively high. The coke loading is formed by gravity from the center to both sides. Since the coke is easy to break, the powder formed during the loading process scatters and spreads, causing serious dusting on site, which not only affects the coke field environment, but also affects the health of the operators on site.

[0003] The main function of the dust extraction device is to reduce the emission of dust into the surrounding environment, protect the environment and the health of the operators, and prevent safety hazards caused by dust accumulation. For example, in a coking plant, the coke storage is an important link in the coke circulation process. The dust extraction device can effectively reduce the dust emission during the coke loading process, improve the working environment, and help maintain the cleanliness and safety of the entire working area. The dust extraction device is installed with a dust extraction hood and a pipeline system at the key position, uses negative pressure wind to suck away the dust generated during the loading process, and is treated by a dust removal equipment, finally realizes the standard emission. When the coke is unloaded, fed and other operations in the storage, the dust is raised, the dust and air mixture is collected by the dust extraction hood, and is pumped to the dust removal equipment under the suction of the dust extraction fan through the dust removal pipeline. In the dust removal equipment, the dust is separated and collected, and the purified air is discharged into the atmosphere after meeting the environmental protection emission standard.

[0004] Currently, when the coke is loaded, the dust extraction device used is usually fixedly installed outside the discharge hopper. Since the dust removal mechanism is large in size and fixed on the discharge hopper, it occupies a large space around the discharge hopper when the discharge hopper is not in use, affecting the normal driving of the vehicle. Therefore, in order to solve the above problems, the utility model provides a detachable dust extraction device for coke loading, to solve the problem that the dust extraction device cannot be detached, resulting in large space occupied by the dust extraction device, thereby affecting the normal driving of the vehicle.
