Description

Technical Field

[0001] The invention relates to the technical field of garbage disposal, in particular to a sorting device for kitchen garbage disposal equipment. Background Art

[0002] Kitchen waste refers to the perishable and degradable waste such as fruits and vegetables and food scraps, leftovers, melon and fruit peels discarded in daily life. It has the characteristics of high water content, high salt and oil content, and is not suitable for landfill or incineration. After searching, the Chinese patent publication number CN218700480U discloses an automatic bag breaking and sorting device for kitchen waste, which belongs to the technical field of kitchen waste treatment, including a body shell, on which two rotating shafts are rotatably arranged, and the two rotating shafts are connected by a conveyor belt transmission. This technical solution cuts the plastic bag by a cutting blade, performs preliminary garbage size screening on the filter, and finally blows the empty plastic bag into the collection bucket by a fan to complete the screening. Although the screening and separation of kitchen waste and plastic bags is achieved, the wind direction is opposite to the entry direction of the garbage during use, so it will affect the falling of the garbage, thereby affecting the sorting of the garbage.

[0003] The Chinese patent publication number CN216104045U discloses a positioning and sorting device for classifying kitchen waste, including a positioning and sorting device, the upper end of which is fixedly connected to a storage device, and the positioning and sorting device includes a conveying belt, a support plate, a chassis, a positioning plate, a first storage box, a second storage box, and a filter plate. Although this technical solution can complete the separation and sorting of solid and liquid, and can achieve the preliminary classification of kitchen waste, which is conducive to the smooth progress of subsequent work, when in use, some oils and fats will be in a solid state at low temperatures, so they cannot be automatically separated and filtered, and thus cannot be completely separated, which affects the effect of garbage sorting.

At this time, the vibration motor can drive the screen 62 to vibrate, and the garbage can be screened. The finer garbage will fall into the collection chamber 64. The fifth motor 65 rotates to drive the second reciprocating screw 66 to rotate, which can drive the second cross plate 67 and the spikes 68 to move back and forth. Under the action of the reset spring, when the spikes 68 coincide with the mesh of the screen 62, they will be nailed into the mesh, thereby pushing out the garbage blocked in the mesh to avoid affecting the screening effect.

[0058] The sieved garbage will fall from the guide plate 71. At this time, the blower 72 and the exhaust fan 77 are running to air-sort the fallen garbage. Heavier garbage such as bones will fall to a closer position, and lighter garbage such as plastic will fall to a farther position, so as to achieve the garbage sorting again. Some lighter garbage such as plastic bags will be adsorbed on the mesh plate 75. At this time, the sixth motor 712 rotates to drive the pulley 79 and the synchronous belt 710 to rotate, and then the scraper 711 can be driven to rotate, so as to scrape off the garbage adsorbed on the mesh plate 75 to avoid affecting the air-selection effect.

[0059] Embodiment 7:

[0060] like Figure 2 and Fig.10As shown, a conveying mechanism 8 cooperating with the air separation mechanism 7 is installed throughout the interior of the garbage disposal box 1.

[0061] Garbage of different weights will fall on the second belt conveyor 83 at different positions, and the second belt conveyor 83 can then convey the corresponding garbage out.

[0062] Working principle: garbage is added through the feed hopper 31, and the rotation of the second motor 32 can drive the roller 33 and the crushing knife 34 to rotate, which can crush some garbage and garbage bags. The crushed garbage will enter the conveying pipe 22, and the rotation of the first motor 26 can drive the rotating shaft 23 and the spiral conveying blade 24 to rotate, which can convey the garbage. The electric heating rod 25 can heat the garbage, so that the solidified grease can be melted, which is convenient for subsequent separation.

[0063] The heated garbage enters the filter mesh tube 42, and the melted grease and water will flow down through the filter mesh tube 42 and enter the collection box 41, so that the garbage can be preliminarily sorted. In the process of filtering grease and water, the rotation of the third motor 43 can drive the filter mesh tube 42 to rotate, and the operation of the air pump 44 can aerate and clean the filter mesh tube 42 through the aeration pipe 45 to avoid blockage of the filter mesh tube 42 and affect the filtration.

Under the action of the reset spring, when the spike 68 coincides with the mesh of the screen 62, it will be nailed into the mesh, thereby ejecting the garbage blocked in the mesh to avoid affecting the screening effect.

[0065] The sieved garbage will fall from the guide plate 71. At this time, the blower 72 and the exhaust fan 77 are running to air-sort the fallen garbage. Heavier garbage such as bones will fall to a closer position, and lighter garbage such as plastic will fall to a farther position, so as to achieve the garbage sorting again. Some lighter garbage such as plastic bags will be adsorbed on the mesh plate 75. At this time, the sixth motor 712 rotates to drive the pulley 79 and the synchronous belt 710 to rotate, and then the scraper 711 can be driven to rotate, so as to scrape off the garbage adsorbed on the mesh plate 75 to avoid affecting the air-selection effect.

[0066] Garbage of different weights will fall on the second belt conveyor 83 at different positions, and the second belt conveyor 83 can then convey the corresponding garbage out.
