Description

Technical Field

[0001] The utility model relates to the technical field of coal sheds, in particular to a coal shed with dustproof effect. Background Art

[0002] Coal shed is used for coal storage. The structure of coal shed requires large span and high clearance to meet the storage and working space.

[0003] As the country's environmental protection requirements continue to increase, the coal yard is required to be transformed into a fully enclosed form, using a large-span steel structure grid or truss structure, which can effectively prevent the coal dust from emitting outward and protect the surrounding environment. Because there are bucket wheel stackers and coal pushers in the coal yard that are constantly performing mechanical operations, coal dust and fine coal particles are constantly emitted into the coal shed. The large amount of coal dust and coal particles emitted in the air not only have an adverse effect on the coal shed and the environment around the coal shed. At the same time, the coal pile in the coal shed will release methane, carbon monoxide and other flammable gases during the slow oxidation process, which will explode when combined with oxygen in the coal shed. Therefore, the above measures also make the internal working environment of the coal shed poor and there are certain safety hazards.

[0004] For this purpose, a coal shed with dust-proof effect is proposed. Utility Model Content

[0013] Specifically, the motor drives the fan blades to rotate, causing the fan blades to draw air inside the shed into the delivery pipe, while assisting the fan drive to draw the gas entering the delivery pipe and transport it to the outside.

[0014] Furthermore, the power of the booster fan is greater than the power of the motor, and the exhaust end of the booster fan is connected to an exhaust gas treatment device.

In conjunction with the exhaust mechanism, the air inside the coal shed can be replaced more quickly, ensuring the safety quality of the air inside the coal shed and greatly improving the practicability of the device.
