Description

A landfill waste sorting device Technical Field

[0001] This utility model relates to the technical field of waste sorting and treatment, and in particular to a landfill waste sorting device. Background Technology

[0002] With the acceleration of urbanization, the amount of urban waste is increasing day by day. Landfill is one of the important ways to deal with waste, which involves the processes of waste sorting, crushing and landfilling.

[0003] In particular, existing landfill waste sorting devices are unable to effectively handle bagged waste packaged in plastic film. The plastic film prevents the waste inside from being fully released, making subsequent sorting inaccurate. These plastic films are also difficult to collect, which seriously affects the operation of the equipment and the effectiveness of waste sorting. Summary of the Invention

[0004] In order to improve the problems in the waste sorting process in the above-mentioned background art, this utility model provides a landfill waste sorting device.

[0005] The landfill waste sorting device provided by this utility model adopts the following technical solution:

[0006] A landfill waste sorting device includes an air separation chamber, a crushing box at the input end of the air separation chamber, a crushing mechanism for crushing packaging film inside the crushing box, a fan installed at the air inlet at the front end of the air separation chamber, multiple sorting ports arranged sequentially at the bottom of the air separation chamber along the output direction of the fan, and a cyclone separator for separating packaging film installed at the air outlet at the end of the air separation chamber.

[0007] Preferably, the crushing mechanism includes multiple horizontally arranged crushing rollers, which are driven by a motor installed on one side of the crushing box in conjunction with a transmission mechanism. Crushing blades are arranged at intervals around the crushing rollers, and the crushing blades on the multiple crushing rollers are staggered.

[0008] Preferably, the sorting port includes a heavy material outlet and a light material outlet in sequence along the output direction of the fan, and a conveying mechanism is provided at the bottom of the sorting port.

[0009] Preferably, a spoiler is provided above the sorting port, and the spoiler is inclined toward the sorting port.

[0010] Preferably, the end of the baffle is fixed to the side wall of the air separation chamber.

[0011] Preferably, a pressure sensor is provided on the inner wall of the air separation chamber, and the pressure sensor is electrically connected to a control box located outside the air separation chamber, and the fan speed is adjusted through the control box.

[0012] Preferably, the sidewall of the air separation chamber is provided with an observation window.

[0013] In summary, this utility model has the following beneficial technical effects:

[0014] 1. This utility model improves the problem of poor sorting effect of waste with film packaging in the prior art by setting a crushing box at the input end of the air separation chamber and using crushing toothed blades to cut open the packaging film on the surface of the waste, so that the waste in the garbage bag can be fully released, and achieves more accurate sorting of waste.

[0015] 2. This utility model uses air separation to classify waste into heavy and light materials. At the same time, a cyclone separator is installed at the air outlet of the air separation chamber. The cyclone separator separates and recycles the packaging film fragments that are crushed by the crushing mechanism and mixed in the airflow, preventing the waste film from clogging the blower during airflow circulation and ensuring the waste treatment effect.

[0021] The present invention will be further described in detail below with reference to Figures 1-4.

[0022] This utility model discloses a landfill waste sorting device.

[0023] Referring to Figures 1, 2, and 3, a landfill waste sorting device includes an air separation chamber 1, a crushing box 2 at the input end of the air separation chamber 1, a crushing mechanism 3 for crushing packaging film inside the crushing box 2, a blower 4 installed at the air inlet at the front end of the air separation chamber 1, multiple sorting ports 5 arranged sequentially at the bottom of the air separation chamber 1 along the output direction of the blower 4, and a cyclone separator 6 for separating packaging film installed at the end of the air separation chamber 1.

[0024] Referring to Figures 2, 3, and 4, the crushing mechanism 3 includes multiple horizontally arranged crushing rollers 7. The crushing rollers 7 are driven by a motor 8 installed on one side of the crushing box 2 in conjunction with a transmission mechanism. The motor 8 is installed on one side of one of the crushing rollers 7, driving this crushing roller 7 to rotate. At the same time, a toothed disc and a transmission chain are installed on the output shaft of the motor 8 to drive the other crushing rollers 7, thereby driving all the crushing rollers 7 to rotate. Crushing cutters 9 are arranged at intervals around the crushing rollers 7, and the crushing cutters 9 on the multiple crushing rollers 7 are staggered.

[0025] Referring to Figures 1, 2, and 3, the sorting port 5 includes a heavy material outlet 10 and a light material outlet 11 in sequence along the output direction of the blower 4. A conveying mechanism 12 is provided at the bottom of the sorting port 5 to convey the sorted waste.

[0026] The airflow output by the blower 4 separates the waste into heavy and light materials. The heavier materials, such as metal and soil, fall to the heavy material outlet 10 after being slightly disturbed by the airflow. The heavy material outlet 10 is equipped with a buffer layer to cushion the falling heavy materials. The lighter materials, such as plastic and paper fragments, are more severely disturbed by the airflow and fall to the light material outlet 11 after moving a distance. The packaging film crushed by the crushing mechanism 3 is the lightest and moves with the airflow to the end of the air separation chamber 1 and enters the cyclone separator 6. The packaging film sinks and separates in the cyclone separator 6, and the airflow is discharged at the airflow outlet at the top of the cyclone separator 6. The airflow outlet at the top of the cyclone separator 6 can also be connected to a bag filter.

[0027] Referring to Figures 1, 2, and 3, a baffle plate 13 is provided above the sorting port 5. The lower end of the baffle plate 13 is inclined toward the sorting port 5. The end of the baffle plate 13 is tightened and fixed to the side wall of the air separation chamber 1 by bolts 14. The baffle plate 13 can slow down the airflow passing through the sorting port 5 at the corresponding position and block the garbage, so that the garbage falls into the corresponding sorting port 5.

[0028] Referring to Figures 1 and 3, a pressure sensor 16 is installed on the inner wall of the air separation chamber 1. The pressure sensor 16 is electrically connected to a control box 17 located outside the air separation chamber 1. The pressure sensor 16 detects the internal airflow pressure, transmits the electrical signal to the control box 17, and adjusts the speed of the fan 4 through the control box 17. An observation window 15 is provided on the side wall of the air separation chamber 1 for easy observation by personnel.

[0029] The implementation principle of a landfill waste sorting device according to this utility model embodiment is as follows: the waste to be processed is transported to the crushing box 2, the crushing mechanism 3 cuts open the packaging film on the surface of the waste, so that the waste in the waste bag is fully released, the blower 4 is started to blow air into the air separation chamber 1, the heavier material falls to the heavy material outlet 10, and the lighter material moves a distance and falls to the light material outlet 11, thus realizing the sorting of waste. The crushed packaging film enters the cyclone separator 6 along with the airflow for separation.

[0030] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
