Embodiment 1

[0037] refer to figure 1 According to an embodiment of the present invention, a waste pretreatment system for using kitchen waste for insect breeding is provided, comprising a raw material bin 2; a shaftless screw conveyor 3 arranged at the bottom of the raw material bin 2; The grid filter 4 at the bottom of the bin 2 is connected to the shaftless screw conveyor 3; the material pump 5 arranged at the bottom of the raw material bin 2 is connected to the grid filter 4; Crusher 6 connected to device 4 and material pump 5; Sand water separator 7 connected to said crusher 6; Screw pressure dehydrator 11 connected to said sand water separator 7; Connected grinder 16.

[0038] The raw material bin 2 is used for storing food waste 1 .

[0039] The shaftless screw conveyor 3 arranged at the bottom of the raw material bin 2 is used to transport the kitchen waste 1 . Shaftless screw conveyor 3 is composed of drive mechanism (motor reducer, transmission shaft), U-shaped groove and brac...

Embodiment 2

[0054] refer to figure 2 According to an embodiment of the present invention, a waste pretreatment system for using kitchen waste for insect breeding is provided, comprising a raw material bin 2; a shaftless screw conveyor 3 arranged at the bottom of the raw material bin 2; The grid filter 4 at the bottom of the bin 2 is connected to the shaftless screw conveyor 3; the material pump 5 arranged at the bottom of the raw material bin 2 is connected to the grid filter 4; Crusher 6 connected to device 4 and material pump 5; Sand water separator 7 connected to said crusher 6; Screw pressure dehydrator 11 connected to said sand water separator 7; connected grinder 16; brewing tank 17 connected with said grinder 16.

[0055] The raw material bin 2 is used for storing food waste 1 .

[0056] The shaftless screw conveyor 3 arranged at the bottom of the raw material bin 2 is used to transport the kitchen waste 1 . Shaftless screw conveyor 3 is composed of drive mechanism (motor reduc...

Embodiment 3

[0075] Such as image 3 As shown, the embodiment of the present invention also provides a garbage pretreatment method for using kitchen garbage for insect breeding, including the following steps.

[0076] Step 101: Use the raw material warehouse to store kitchen waste.

[0077] In some embodiments, a raw material bin can be provided, and the raw material bin can be used to store kitchen waste.

[0078] Step 102: Conveying the kitchen waste flowing out of the raw material bin through a shaftless screw.

[0079] In some embodiments, a shaftless screw conveyor can be set at the bottom of the raw material bin, and the shaftless screw conveys the food waste flowing out of the raw material bin, and the shaftless screw conveyor only plays the role of pushing the food waste forward . However, if the food waste is transferred from the raw material warehouse to other equipment, the shaftless screw conveyor cannot be used, because the food waste has a high fluidity and will flow backw...

Abstract

The invention relates to the field of garbage treatment, in particular to a garbage pretreatment system and method using kitchen garbage to feed insects. The system comprises a raw material bin, a shaftless spiral conveyor, a grid filter, a material pump, a crusher, a sand-water separator, a screw compression dewatering machine and a grinding machine, wherein the shaftless spiral conveyor is arranged at the bottom of the raw material bin; the grid filter is arranged at the bottom of the raw material bin and connected with the shaftless spiral conveyor; the material pump is arranged at the bottom of the raw material bin and connected with the grid filter; the crusher is connected with the grid filter and the material pump; the sand-water separator is connected with the crusher; the screw compression dewatering machine is connected with the sand-water separator; the grinding machine is connected with the screw compression dewatering machine. The garbage pretreatment system has the advantages that the kitchen garbage is filtered first, conveyed separately and crushed, impurities are sorted, a large amount of the kitchen garbage can be treated, equipment blocking can be avoided, continuous normal operation of equipment can be guaranteed, high-quality insect protein can be obtained, and high economic value is achieved.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to a garbage pretreatment system and method for using kitchen garbage for insect breeding. Background technique [0002] Traditional food waste is generally treated by landfill or anaerobic / aerobic fermentation. The landfill method is not friendly to the environment and does not conform to the concept of sustainable development. The products of anaerobic decomposition also contain many thermophilic bacteria and will cause serious pollution to the environment. Although the aerobic fermentation method produces available inorganic substances, it still requires the docking and transformation of subsequent systems. [0003] In addition, there are a lot of food waste and debris, and the next process of food waste entering from the raw material warehouse is to remove impurities. The current treatment method is anaerobic fermentation. The current most is to use the shaft screw conveyor (...
