Description

Technical Field

[0001] The utility model relates to the field of air separators, in particular to a composite air separator. Background Art

[0002] The existing air separators mainly use wind power to separate waste materials with different densities and different particle sizes into required light and heavy substances; this causes the air separator to be unable to perform secondary screening on light substances, affecting the subsequent recycling of different light substances.

[0003] In view of the existence of the above problems, it is necessary to study a composite air separator, which can perform secondary screening on light substances, thus facilitating the subsequent different recycling of different light substances. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a composite air separator, which can perform secondary screening on light substances, thus facilitating the subsequent different recycling of different light substances.

[0005] To achieve the above object, the solution of the utility model is:

[0006] A composite air separator, which comprises a machine chamber, a feeding conveying device, and a particle screening device; the machine chamber is provided with a communicating separation chamber and a sedimentation chamber; one end of the separation chamber away from the sedimentation chamber is provided with a feeding channel, the separation chamber is also provided with a heavy substance discharging channel and an air inlet channel for connecting a fan, the heavy substance discharging channel is arranged lower than the feeding channel, the air inlet channel is on the side of the separation chamber away from the sedimentation chamber and is located between the feeding channel and the heavy substance discharging channel, and the air outlet end of the air inlet channel faces the communication part between the separation chamber and the sedimentation chamber; one end of the sedimentation chamber away from the separation chamber is provided with a first light substance discharging channel, and the sedimentation chamber is also provided with a second light substance discharging channel lower than the first light substance discharging channel; the feeding conveying device passes through the feeding channel of the separation chamber; the particle screening device is installed in the sedimentation chamber and is higher than the second light substance discharging channel, and the discharging end of the particle screening device is matched with the first light substance discharging channel of the sedimentation chamber.

[0007] The particle screening device is a star disk screen, a vibrating screen or a relaxation screen.

[0008] The composite air separator further comprises a discharging conveying device, the discharging conveying device is installed in the sedimentation chamber and is located below the particle screening device, and the discharging end of the discharging conveying device is matched with the second light substance discharging channel of the sedimentation chamber.

[0009] The discharging conveying device and the particle screening device are arranged obliquely upward along the direction from the separation chamber to the sedimentation chamber.

[0010] The discharging conveying device is a belt conveyor.

[0011] The feeding and conveying device is a belt conveyor.

[0012] The composite air classifier further includes a material leveling roller, which is rotatably installed at the connection between the separation chamber and the sedimentation chamber.

[0013] The air inlet channel is arranged obliquely upward in the direction from the separation chamber to the sedimentation chamber.

[0014] After adopting the above scheme, the working principle of the composite air classifier of the present invention is as follows: The feeding and conveying device feeds the material into the separation chamber from the feeding channel. The heavy substances in the material entering the separation chamber will fall into the heavy substance discharge channel under the action of their own gravity and be discharged from the heavy substance discharge channel. The light substances in the material entering the separation chamber will be blown into the sedimentation chamber and fall onto the particle screening device under the action of the wind input by the air inlet channel. The particle screening device screens the light substances to screen out large particle light substances and small particle light substances. The large particle light substances are sent by the particle screening device to the first light substance discharge channel and discharged from the first light substance discharge channel, and the large particle light substances enter the second light substance discharge channel and are discharged from the second light substance discharge channel.

[0015] As can be seen from the above, the composite air classifier of the present invention can first separate heavy substances and light substances by air separation, and then screen the light substances through the particle screening device to screen out large particle light substances and small particle light substances. In this way, the present invention can realize the re-screening of light substances, which is beneficial to the subsequent different recycling of different light substances. In addition, the particle screening device of the present invention is installed in the sedimentation chamber of the machine chamber, so that the installation space of the particle screening device overlaps with that of the machine chamber, which helps to make the structure of the composite air classifier of the present invention compact. Compared with the existing air classifiers, the composite air classifier of the present invention does not require additional floor space. Description of the Drawings
