Detailed Description
In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the invention only and are not intended to limit the scope of the invention.
As shown in fig. 1-2, the present invention comprises: the vacuum device comprises a fan 1 and an air extraction structure, wherein the air extraction structure is connected with the fan 1 through a header pipe 7; the air exhaust structure comprises a vacuum chamber 4, the vacuum chamber 4 is provided with a negative pressure pipe connector 2 and an air exhaust port, a header pipe 7 is connected with the air exhaust port, the air exhaust port is provided with a filtering structure 3, and the lower end of the vacuum chamber 4 is connected with a dust exhaust chamber 5 for receiving and filtering dust.
Be equipped with the mount that is used for fixed filtration 3 in the vacuum storehouse 4, the mount is located between negative pressure pipe interface 2 and filtration 3, and filtration 3 passes through the spring to be fixed on the mount, and the lower extreme in vacuum storehouse 4 is funnel type structure, and the dust of being convenient for is concentrated to fall to the dust removal storehouse 5 in, and filtration 3 and second filtration 601 are folding air filter, and this kind of filter core is with low costs, and filtered air is effectual.
The setting of mount for fixed filtration 3 of buffering, this structure carries out air filter before bleeding, prevents that the dust of inhaling from damaging the fan. And meanwhile, the filtered dust is collected uniformly and intensively.
In order to prevent the fan from being damaged due to large load, the main pipe 7 is further provided with another branch pipe, the branch pipe is connected with a pneumatic butterfly valve 6, the other end of the pneumatic butterfly valve 6 is provided with an air supplementing port, and the air supplementing port is provided with a second filtering structure 601.
For convenient use, the vacuum device is also provided with a rack with universal wheels, the fan 1 is fixed on the rack, the fan 1 is controlled by the control cabinet 8, the rack comprises a support plate for fixing the control cabinet and the vacuum bin 4, and the control cabinet and the vacuum bin are respectively positioned on two sides of the support plate.
