[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] Please refer to Figures 1-4 The utility model provides a technical scheme:

[0024] A stable type winnowing machine for household garbage sorting system, including winnowing bin 1, winnowing bin 1 top and one side are integrated with feed inlet 3 and discharge port one 4 respectively, winnowing bin 1 front side is fixedly connected with centralized bin 2, and the bottom of centralized bin 2 is inclinedly arranged, and the bottom of centralized bin 2 is integrated with discharge port two 5 on one side, winnowing bin 1 rear end is fixedly connected with multiple groups of through seat 11, and multiple groups of through seat 11 are integrated with electric fan 14 inside, winnowing bin 1 is integrated with multiple groups of guide plate 12 for connecting feed inlet 3 and discharge port one 4 inside;

[0025] The garbage handled by the preceding device is transferred from feed inlet 3 to the uppermost guide plate 12, and in the process of sliding along the guide plate 12 and falling to the next layer of guide plate 12, the corresponding electric fan 14 in the area of winnowing bin 1 can generate air power, which can blow the smaller garbage into centralized bin 2, and so on, until the main garbage is guided out from discharge port one 4, and centralized bin 2 can concentrate the garbage separated from each area and finally guide out from discharge port two 5, which replaces the traditional conveying belt by falling, so that the air power better contacts the garbage of different weights, and the multiple groups of guide plates 12 staggeredly distributed can effectively slow down the falling time of garbage, further ensuring the winnowing effect.

[0026] Specifically, as Figure 2 and Figure 4As shown, a side plate 7 is fixedly connected to the outer wall of the central chamber 2. The side plate 7 is detachably connected to the outer wall of the air separation chamber 1. A U-shaped clamping sleeve 8 is fixedly connected to the outer wall of the air separation chamber 1. The inner wall of the clamping sleeve 8 engages with the outer wall of the side plate 7, and the clamping sleeve 8 and the side plate 7 are fixedly connected by a locking rod 9. The engagement of the side plate 7 and the clamping sleeve 8 facilitates the quick alignment of the air separation chamber 1 and the central chamber 2. The insert is fixed to the clamping sleeve 8 by the locking rod 9, thus ensuring the stability of the connection between the air separation chamber 1 and the central chamber 2. At the same time, the central chamber 2 can be easily disassembled and assembled later, which is convenient for the internal inspection and maintenance of the air separation chamber 1 and the central chamber 2, thereby improving the ease of use of the stable air separator used in the municipal solid waste sorting system.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, a connecting frame 10 is fixedly connected to the side of the air separator 1 to connect the air separator to the preceding equipment. A base frame 6 is fixedly connected to the bottom of the air separator 1 to further ensure the overall stability of the air separator. Multiple sets of guide plates 12 are distributed in an inclined and staggered manner, and multiple sets of electric fans 14 correspond to the intersection area of ​​multiple sets of guide plates 12. The fans replace the traditional conveyor belt by falling, which allows the aerodynamics to better contact the waste of different weights. The staggered distribution of multiple sets of guide plates 12 can effectively slow down the time it takes for the waste to fall. Protective nets 13 are fixedly connected to the inner surface of multiple sets of through seats 11 to prevent waste from falling into the through seats 11.

[0028] Working principle: After being processed by the preceding equipment, the waste is transferred from the inlet 3 to the uppermost guide plate 12. As the waste slides down the guide plate 12 and falls to the next guide plate 12, the electric fan 14 in the corresponding area of ​​the air separation chamber 1 generates aerodynamic force. This force blows smaller pieces of waste into the collection chamber 2, and so on, until the main body of waste is discharged from the outlet 4. The collection chamber 2 can collect the waste separated from each area and finally discharge it from the outlet 5. The falling method replaces the traditional conveyor belt, making the aerodynamic force more efficient. The air separator allows for better contact with waste of different weights, and the staggered distribution of multiple sets of guide plates 12 effectively slows down the time it takes for waste to fall, further ensuring the effect of air separation. The combination of the side plate 7 and the sleeve 8 facilitates the quick alignment of the air separation chamber 1 and the central chamber 2. The insert plate is fixed to the sleeve 8 by the locking rod 9, which ensures the stable connection between the air separation chamber 1 and the central chamber 2. At the same time, it allows for convenient disassembly and assembly of the central chamber 2, which is convenient for the internal inspection and maintenance of the air separation chamber 1 and the central chamber 2. This improves the ease of use of the stable air separator for the municipal solid waste sorting system.

[0029] The foregoing description of the embodiments enables one of ordinary skill in the art to make or use the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
