Wet acetylene automatic unloading calcium carbide crushing explosion-proof dehumidification ash-free dust removal system

Abstract

The invention relates to a wet acetylene automatic unloading calcium carbide crushing explosion-proof dehumidification ash-free dust removal system. The system comprises a rolling door and an exhaustfan arranged in an unloading area. A rolling door controlling device used for controlling the rolling door to roll and unroll is arranged on the upper part of the rolling door. The rolling rood controlling device, a power source, a motor driving the exhaust fan, and a speed regulating switch of the motor form an electric circuit. When the rotating speed of the motor increases, the rolling door controlling device is suitable for increasing opening of the rolling door. When the rotating speed of the motor decreases, the rolling door controlling device is suitable for decreasing the opening of the rolling door. The lifting height of the rolling door is controlled by the rolling door controlling device, and therefore the lifting height is in direct proportion to the rotating speed of the motor, and the rotating speed of the exhaust fan is in direct proportion to the lifting height of the rolling door.

Description

technical field [0001] The invention relates to a wet-process acetylene automatic unloading calcium carbide crushing explosion-proof dehumidification and dust-free dust removal system, which can improve the efficiency of unloading and dust removal. Background technique [0002] The calcium carbide automatic unloading crushing and dust removal system in the prior art generally has a screen door in the calcium carbide unloading area. After the transport vehicle transports the calcium carbide to the unloading area, the screen door is closed to prevent Dust will not leak to the outside world. However, the screen door also blocks outside air from entering the unloading area. During the working process of the exhaust fan in the unloading area, due to the restriction of the amount of air added into the unloading area, the exhaust air volume of the exhaust fan is also limited, thereby reducing The exhaust efficiency of the exhaust fan slows down the dust extraction speed in the unl...

AI Technical Summary

Problems solved by technology

However, the screen door also blocks outside air from entering the unloading area. During the working process of the exhaust fan in the unloading area, due to the restriction of the amount of air added into the unloading area, the exhaust air volume of the exhaust fan is also limited, thereby reducing The exhaust efficiency of the exhaust fan slows down the dust extraction speed in the unloading area

At the same time, due to the reduced air volume, the flow rate of the air in the unloading area becomes slower, which makes it easy for the dust to spread from the unloading hopper of the transport vehicle to the surroundings, making it easier for dust to adhere to the walls and screen doors of the unloading area.

In addition, when the dust-laden airflow passes through the variable diameter of the ventilation duct and the turning elbow, the flow velocity slows down, making it easy for dust to deposit here. There are dust removal valves on the wall, and these parts are cleaned regularly by manually opening the valves. The cleaning process is time-consuming and laborious, and the ventilation pipes must be shut down.
