Embodiment 1

[0054] This embodiment provides a biological treatment method for resource utilization of kitchen waste. The biological treatment method includes the following steps:

[0055] S1. Unloading and sorting the food waste to obtain materials to be processed.

[0056] S2. Crushing the material to be processed, and extruding and dehydrating the crushed product.

[0057] S3, performing microbial treatment on the product after extrusion dehydration, and drying the product after microbial treatment.

[0058] S4. Grinding the dried product.

[0059] S5, granulating the pulverized product.

[0060] Wherein, in step S5, a granulation equipment is used to granulate the pulverized product.

[0061] see figure 1 , figure 2 As shown, the granulation equipment includes: a granulation box 1 , an extrusion mechanism 2 , a cleaning mechanism 3 , a roll surface monitoring component 4 and a controller 5 .

[0062] A material inlet 101 is provided on the top of the granulation box 1 . In this...

Embodiment 2

[0085] see Figure 5 , this embodiment provides a biological treatment method for resource utilization of kitchen waste. In this embodiment, on the basis of Embodiment 1, the granulation equipment may further include a feeding mechanism 6 .

[0086] Please combine Figure 6 and Figure 7 , The feeding mechanism 6 is arranged on the top of the granulation box 1 . The feeding mechanism 6 includes a feeding hopper 61 and a leveling assembly 62 . The inside of the feeding hopper 61 communicates with the feeding port 101 . The screed component 62 is arranged above the material inlet 101 . The screed assembly 62 includes a screed rod 621 , multiple claws 622 , and a driving motor 623 . The driving motor 623 is arranged on the hopper 61 . One end of the screed rod 621 is fixedly connected with the output shaft of the driving motor 623 . In this embodiment, the driving motor 623 may be a stepping motor, and the controller 5 controls the output end of the driving motor 623 to r...

Embodiment 3

[0090] see Figure 8 and Figure 9 , this embodiment provides a biological treatment method for resource utilization of kitchen waste. In this embodiment, on the basis of Embodiment 1 or Embodiment 2, the granulation equipment may further include a collection box one 8 , a collection box two 9 , and a material guide plate 10 .

[0091] Collection box one 8 is positioned at the below of extruding mechanism 2 material falling points, and collection box can be installed in the granulation box 1 movably, thereby can be convenient to collection box can be taken out from granulation box 1 inside when collection box is stored full.

Abstract

The invention relates to a kitchen waste resource utilization biological treatment method which adopts granulation equipment. The granulation equipment comprises a granulation box, an extrusion mechanism, cleaning mechanisms, a roller surface monitoring assembly and a controller. The extrusion mechanism comprises an extrusion motor and two extrusion rollers. The tangent position of the two extrusion rollers is located below a feeding port of the granulation box. Each cleaning mechanism corresponds to one extrusion roller and is used for cleaning the roller surface of the extrusion roller. Each cleaning mechanism comprises a mounting plate, a brush and a telescopic piece. The brushes are fixed on the mounting plates, and the mounting plates are arranged in the granulation box and can move to enable the brushes to be in contact with or separated from the roller surfaces of the extrusion rollers. The telescopic pieces are fixed on the granulation box and are used for driving the mounting plates to move. According to the kitchen waste resource utilization biological treatment method, the surfaces of the extrusion rollers can be cleaned in good time, residual materials on the surfaces of the extrusion rollers are removed, the yield of extruded particles is increased, and the situation that the extrusion rollers are subjected to long-time friction, and consequently the granulation effect is reduced can be avoided.

Description

technical field [0001] The invention relates to the technical field of kitchen waste treatment, in particular to a biological treatment method for resource utilization of kitchen waste. Background technique [0002] Kitchen waste is a kind of domestic waste formed by residents in the process of living consumption, and various organic substances contained in it are easily corroded in summer. At present, the treatment methods of domestic kitchen waste mainly include chemical treatment and biological treatment. The chemical treatment method uses chemical reactions to decompose the organic matter in the food waste by adding chemical substances, and then landfills it. The advantage of this method is that it is simple and efficient, but the disadvantage is that a large amount of useful substances in the kitchen waste are wasted, and it is easy to cause secondary pollution. Biological treatment is to transform food waste into fertilizer or feed that can be used in agriculture and ...
