Description

Technical Field

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

[0002] Air separation is a method of removing impurities with the help of wind power by utilizing the difference in suspension speed between materials and impurities. The purpose of air separation is to remove light impurities and dust, while also removing some heavier impurities such as stones and soil. It is used in garbage sorting to remove heavier metal materials in the garbage, making it easier to classify and process the garbage.

[0003] After completing air separation, most sorting machines discharge the airflow through the outlet. Since the lighter garbage is carried by the airflow, it will cause dust to float. At the same time, the dust will follow the flow of the airflow and adhere to the filter, causing blockage of the filter and affecting the screening effect of the air separator. Therefore, a domestic waste air separator is proposed to solve the above problems. Utility Model Content

Since the lighter garbage is carried up by the airflow, it will cause dust to float. At the same time, the dust will follow the flow of the airflow and adhere to the filter, causing the filter to be blocked, thus affecting the screening effect of the air separator.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a domestic garbage air separator, comprising an air separator body, an air separator body having an air separator structure disposed therein, and a cleaning structure disposed therein;

[0007] The cleaning structure includes a filter, a fixed plate, a screw, a threaded block, a servo motor, a rotating rod, a cleaning brush, a gear and a toothed plate. The filter is fixedly installed inside the air separator body, the fixed plate is fixedly installed inside the air separator body, a screw is movably installed outside the fixed plate, the external thread of the screw is connected with a threaded block, the external fixed plate of the fixed plate is fixedly installed with a servo motor, the external rotating rod is movably installed outside the threaded block, the external rotating rod of the rotating rod is fixedly installed with a cleaning brush, the external rotating rod is fixedly installed with a gear, and the external part of the gear is meshed with a toothed plate.

[0008] Furthermore, the feeding conveyor passes through the air separator body and extends into the interior of the air separator body, and the air nozzle passes through the air separator body and extends into the interior of the air separator body.

[0009] Furthermore, the driving motor passes through the air separator body and is fixedly connected to the material-selecting roller, and the air outlet tube is close to the filter screen.

[0010] Furthermore, the servo motor passes through the fixing plate and is fixedly connected to the screw rod, and the cleaning brush is in contact with the filter screen.

[0011] Furthermore, the number of the fixing plates is four, and the four fixing plates are respectively located on the upper and lower sides of the screw rod and the tooth plate.

[0022] The air separation structure 2 includes a feeding conveyor 201, a fan 202, an air nozzle 203, a driving motor 204, a material discharging roller 205 and an air outlet tube 206. The feeding conveyor 201 is arranged inside the air separation machine body 1, the fan 202 is fixedly installed outside the air separation machine body 1, the air nozzle 203 is fixedly installed outside the fan 202, the driving motor 204 is fixedly installed outside the air separation machine body 1, the material discharging roller 205 is movably installed inside the air separation machine body 1, and the air outlet tube 206 is fixedly installed outside the air separation machine body 1.

[0023] The cleaning structure 3 includes a filter 301, a fixed plate 302, a screw 303, a threaded block 304, a servo motor 305, a rotating rod 306, a cleaning brush 307, a gear 308 and a tooth plate 309. The filter 301 is fixedly installed inside the air separator body 1, the fixed plate 302 is fixedly installed inside the air separator body 1, the screw 303 is movably installed outside the fixed plate 302, the threaded block 304 is threadedly connected to the outside of the screw 303, the servo motor 305 is fixedly installed outside the fixed plate 302, the rotating rod 306 is movably installed outside the threaded block 304, the cleaning brush 307 is fixedly installed outside the rotating rod 306, the gear 308 is fixedly installed outside the rotating rod 306, and the tooth plate 309 is meshed with the outside of the gear 308.

[0024] exist Figure 2In the process, the material-discharging roller 205 separates the light garbage discharge port and the heavy garbage discharge port, which can effectively prevent the two types of garbage from being mixed during discharge, resulting in inaccurate garbage screening.

[0025] exist Figure 3 In the embodiment, the fixing plate 302 fixes the positions of the screw rod 303 and the tooth plate 309 and limits the position of the cleaning brush 307 , so that the cleaning brush 307 can clean the filter screen 301 .

[0026] exist Figure 3 In the embodiment, the gear 308 moves outside the tooth plate 309, and through the connection between the threaded block 304 and the rotating rod 306, the gear 308 can be meshed with the tooth plate 309 and drive the rotating rod 306 to rotate.

[0027] To sum up, in the domestic waste air separator, after the dust is filtered by the filter 301 by setting the horizontal airflow, the dust will be adsorbed on the filter 301, and the servo motor 305 drives the screw 303 to rotate, so that the threaded block 304 moves and drives the rotating rod 306 to move. When the gear 308 outside the rotating rod 306 rotates on the tooth plate 309, it can drive the cleaning brush 307 to rotate and clean the filter 301, thereby reducing the blockage of the filter 301.

[0028] In addition, the domestic waste air separator, by setting up a feeding conveyor 201, transports the garbage to the inside of the air separator body 1, and can transmit wind force to the air nozzle 203 according to the fan 202, so as to blow up the light garbage dropped from the feeding conveyor 201, while the heavy garbage will fall vertically. Through the cooperation of the airflow and the material-dispensing roller 205, the garbage can be well classified, which solves the problem that most sorting machines discharge the airflow through the air outlet after completing the air separation. Since the lighter garbage is carried up by the airflow, it will cause dust to float, and at the same time, the dust will follow the flow of the airflow and adhere to the filter 301, causing clogging of the filter 301 and affecting the screening effect of the air separator.
