Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the device comprises a bypass pipeline 1, a leakage detection cup 2, a dust concentration sensor 3 and a PLC, wherein an air inlet end of the bypass pipeline 1 is communicated with an air outlet end of a bag-type dust collector 4, a hole is formed in the bottom side of the bypass pipeline 1, a cup opening of the leakage detection cup 2 is communicated with the hole, the cup opening of the leakage detection cup 2 faces upwards, the dust concentration sensor 3 is arranged inside the leakage detection cup 2, an output end of the dust concentration sensor 3 is connected with an input end of the PLC, and the PLC is used for controlling starting and stopping of the bag-type dust collector 4.
In order to timely close the bypass pipeline 1 when leakage is detected, the dust prevention device further comprises an electromagnetic valve 5 arranged at an air inlet of the bypass pipeline 1, and the input end of the electromagnetic valve 5 is connected with the output end of the PLC.
In order to timely send out an alarm to the working personnel when leakage is detected, the leakage alarm device further comprises an alarm device, and the input end of the alarm device is connected with the output end of the PLC.
In order to discharge redundant dust in the bypass pipeline 1, the dust collector further comprises a Roots blower 6, wherein the air inlet end of the Roots blower 6 is communicated with the air outlet end of the bypass pipeline 1, and the air outlet end of the Roots blower 6 is communicated with the atmosphere.
In order to prevent dust in the exhaust bypass pipeline 1 from polluting the environment, the exhaust bypass pipeline also comprises a dust removal air pipe 7, and the air inlet end of the dust removal air pipe 7 is communicated with the air outlet end of the Roots blower 6.
The Roots wind used in the invention has the following principle: the two impellers rotate in opposite directions, gaps among the impellers, the casing and the wall plates are extremely small, so that a vacuum state is formed in an air inlet, air enters an air inlet cavity under the action of atmospheric pressure, then two blades of each impeller, the wall plates and the casing form a sealed cavity, the air in the air inlet cavity is continuously brought to an air outlet cavity by the sealed cavity formed by the two blades in the rotation process of the impellers, and the impellers in the air outlet cavity are meshed with each other, so that the air between the two blades is extruded out, and the air is continuously conveyed to the air outlet from the air inlet in such a way that the air continuously runs.
