[0021] As Figs. 1-3 shown in the figure, the utility model discloses an intelligent self-cleaning construction waste air separator, which comprises an air separator box 200, a feed inlet is formed in the top of the air separator box 200, adjustable baffles 201 and lower adjustable baffles 203 are hingedly connected to the inside of the air separator box 200 through rotating shafts, upper electric push rods 202 and lower electric push rods 204 are hingedly connected to the surfaces of the adjustable baffles 201 and the lower adjustable baffles 203 through rotating shafts respectively, the fixed ends of the upper electric push rods 202 and the lower electric push rods 204 are hingedly connected to the top surface and the bottom surface of the air separator box 200 outside and inside respectively, the adjustable baffles 201 and the lower adjustable baffles 203 realize circular arc motion through the extension and retraction of the upper electric push rods 202 and the lower electric push rods 204, the angle range of the motion is 45°-90°, when the adjustable baffles 201 and the lower adjustable baffles 203 move from the 45° position to the 90° position, the adjustable baffles 201 and the lower adjustable baffles 203 are in the closed state at this time, which is convenient for the air cannon 103 to clean the filter screen 102 mechanically, when the adjustable baffles 201 and the lower adjustable baffles 203 move from the 90° position to the 45° position, the adjustable baffles 201 and the lower adjustable baffles 203 are in the open state at this time, which is convenient for the airflow ejected by the fan 100 and the air separator nozzle 101 to classify the light and heavy construction waste.

[0022] A construction waste feed belt conveyor 300 is installed on the top of the air separator box 200, the discharge end of the construction waste feed belt conveyor 300 is connected with the feed inlet, and the construction waste feed belt conveyor 300 is used for conveying the construction waste from the feed inlet into the air separator box 200.

[0023] Heavy material discharge ports 205 and light material discharge ports 206 are respectively formed in the bottom of the air separator box 200, the heavy material discharge ports 205 and the light material discharge ports 206 are respectively connected with heavy material belt conveyors 301 and light material belt conveyors 302, and can be used for classifying and conveying the light and heavy waste.

[0024] The air blowing mechanism is connected to the side of the air separator box 200, and comprises a fan 100. The air outlet of the fan 100 is connected to an air separator nozzle 101. One end of the air separator nozzle 101 penetrates through and is installed on the side of the air separator box 200. An inlet baffle 207 is installed on the outer top surface of the air separator box 200, and is located below the inlet. When the fan 100 is started, air is blown out from the air separator nozzle 101. After the construction waste enters the air separator, the inlet baffle 207 spreads the construction waste and makes it fall. In the falling process, the air blown out from the air separator nozzle 101 blows on the surface of the construction waste in the falling state, and blows the construction waste with light substances to the periphery of the filter screen 102 to fall. Part of the light substances are attached to the filter screen 102, and most of the light substances fall into the light substance belt conveyor 302 through the light substance discharge port 206. The heavy substances fall into the heavy substance belt conveyor 301 through the heavy substance discharge port 205.

[0025] The air inlet of the fan 100 is connected to an air return pipe 104. One end of the air return pipe 104 penetrates through the other side of the air separator box 200 through a flange and extends into the air separator box 200. A filter screen 102 is installed at the air return port of one end of the air return pipe 104. The air return pipe 104 can discharge the gas in the air separator box 200, thereby improving the stability of the air pressure in the air separator box 200. The filter screen 102 prevents the light substance construction waste from being discharged from the air separator box 200, thereby facilitating the collection of the light substance construction waste.

[0026] One end of the air return pipe 104 is penetrated and installed with an air return port air pressure sensor 106. The detection end of the air return port air pressure sensor 106 extends into the air return pipe 104. As the light substance construction waste attached to the filter screen 102 gradually increases, the filter holes on the filter screen 102 will be blocked, thereby reducing the air permeability of the filter screen 102. The air return port air pressure sensor 106 is used to detect the air flow pressure in the air return pipe 104. When the air flow pressure is lower than the preset value of the air return port air pressure sensor 106, it can be fed back to the PLC controller. The PLC controller controls the fan 100 to stop working, and controls the upper electric push rod 202 and the lower electric push rod 204 to work at the same time. The upper electric push rod 202 and the lower electric push rod 204 drive the upper adjustable baffle 201 and the lower adjustable baffle 203 to move to 90 degrees. At this time, the upper adjustable baffle 201 and the lower adjustable baffle 203 block the inner cavity of the air separator box 200. At this time, the filter screen 102 is subjected to a back blowing operation by the air cannon 103, thereby facilitating the cleaning of the light substance construction waste attached to the filter screen 102. The light substance construction waste falling from the filter screen 102 falls onto the light substance belt conveyor 302.

[0027] The side of the return air pipe 104 is provided with an air cannon 103 through pipeline penetration installation, the air outlet of the air cannon 103 corresponds to the position of the filter screen 102, the air cannon 103 is connected with an air compressor through a hose, the air compressor supplies compressed gas to the air cannon 103, and the air cannon 103 sprays high-pressure gas onto the filter screen 102, so as to clean light material construction waste on the filter screen 102.

[0028] The surface of the air separator box 200 is provided with an air separator air pressure sensor 105 through penetration installation, the detection end of the air separator air pressure sensor 105 extends into the air separator box 200, the air separator air pressure sensor 105 is used for detecting the high and low of the air pressure in the air separator box 200, if the air pressure reaches or is lower than the preset value in the air separator air pressure sensor 105, at this time, the airflow sprayed by the air separator nozzle 101 is too high or too low, when too high, the airflow sprayed by the air separator nozzle 101 can blow the heavy material construction waste to fall onto the light material belt conveyor 302, and when too low, the light material construction waste falls onto the heavy material belt conveyor 301, so that the air separator air pressure sensor 105 can conveniently detect the airflow pressure of classified construction.

[0029] The two symmetrical sides of the air separator box 200 are both provided with two arc-shaped sliding grooves 4, the bottom end of the upper adjustable baffle 201 and the top end of the lower adjustable baffle 203 both extend into the sliding grooves 4 through pivot shafts, the sliding grooves 4 can limit the circular arc movement of the bottom end of the upper adjustable baffle 201 and the top end of the lower adjustable baffle 203, and the stability of the bottom end of the upper adjustable baffle 201 and the top end of the lower adjustable baffle 203 during movement is improved.

[0030] In the scheme, the air compressor, the fan 100, the air separator air pressure sensor 105, the return air port air pressure sensor 106, the lower electric push rod 204, the construction waste feeding belt conveyor 300, the light material belt conveyor 302 and the heavy material belt conveyor 301 are all connected with a PLC controller through wires, the PLC controller is connected with an external power supply through wires, and the device is convenient for automatic control.

[0031] The basic principle, main features and advantages of the device are shown and described above. It should be understood by those skilled in the art that the device is not limited by the above examples, and the above examples and descriptions in the specification are only the principles of the device, and various changes and improvements can be made without departing from the spirit and scope of the device, and these changes and improvements all fall within the scope of the claimed device.
