Aiming at the defects in the prior art, the utility model provides a pneumatic valve air-supplementing vacuum feeding machine, which comprises a vacuum device, wherein the vacuum device comprises a fan and an air-extracting structure, and the air-extracting structure is connected with the fan through a header pipe; the air extraction structure comprises a vacuum bin, the vacuum bin is provided with a negative pressure pipe connector and an air extraction opening, the main pipe is connected with the air extraction opening, the air extraction opening is also provided with a filtering structure, and the lower end of the vacuum bin is connected with a dust exhaust bin for receiving filtered dust; the main pipe is further connected with a pneumatic butterfly valve, the other end of the pneumatic butterfly valve is provided with an air supplementing port, and a second filtering structure is arranged at the air supplementing port.

Furthermore, a fixing frame for fixing the filtering structure is arranged in the vacuum bin, the fixing frame is located between the negative pressure pipe interface and the filtering structure, and the filtering structure is fixed on the fixing frame through a spring.

Set up this structure, filtration and elastic connection between the mount when filterable, also leave the buffering surplus when stable, further protect filtration.

Furthermore, the lower end of the vacuum bin is of a funnel-shaped structure, so that dust can fall into the dust discharge bin conveniently and intensively.

Further, the filter structure and the second filter structure comprise pleated air filter elements. The filter element has low cost and good air filtering effect.

Furthermore, the fan is electrically connected with the control cabinet, so that automatic control is realized.

Furthermore, the fan is fixed in the frame, and including the backup pad of fixed switch board and vacuum storehouse in the frame, switch board and vacuum storehouse are located the both sides of backup pad respectively. In the design, the motor is positioned at a low position, the control cabinet and the vacuum bin are positioned above, the space is saved, and the universal wheels are arranged at the bottom of the rack, so that the whole rack can be conveniently moved.

The utility model has the advantages that:

all the filtering devices are arranged outside the bin and connected with the bin through a negative pressure pipe interface for vacuumizing, so that the filtering devices are convenient to disassemble and clean; meanwhile, the air supplementing port is arranged and controlled through a pneumatic butterfly valve, so that the condition that the fan is burnt out due to overlarge load caused by negative pressure extraction when the fan does not need material supplementing is prevented, and dust sucked in the fan is washed away.

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.
