Description

Technical Field

[0001] The utility model specifically relates to a pre-processing device for garbage power generation. Background Art

[0002] Garbage-to-energy is a technology that uses garbage to convert energy, usually by incineration or gasification. Incineration-to-energy is a technology that converts garbage into energy through the incineration process. The basic principle of this method is to burn garbage under high temperature conditions to generate heat energy, and then use this heat energy to generate steam to drive the generator to generate electricity. During incineration, in order to better burn, large pieces of garbage will be crushed into small pieces, and more liquid mixed in the garbage will be discharged to separate the solid and liquid.

[0003] In the existing waste-to-energy process, the crushing and solid-liquid separation of garbage need to be carried out in two steps, and the garbage needs to be transported between the two, which is relatively time-consuming and laborious. It cannot be completed in one step. In order to simplify the waste-to-energy process and reduce the waste of time and resources in the processing process, we propose a pretreatment device for waste-to-energy. Utility Model Content

[0007] A box body is fixed to the lower surface of the pulverizer, and the box body is provided with an opening connected to the interior of the pulverizer;

[0008] The water filtering mechanism is arranged inside the box body to separate the solid and liquid of the crushed garbage.

[0009] Preferably, the water filtering mechanism includes a first filter plate, a first liquid guide plate, a second filter plate and a second liquid guide plate. The first filter plate, the second filter plate and the second liquid guide plate are sequentially distributed on the inner side of the pulverizer along the height direction of the box body, and the first filter plate and the side wall of the box body form a feeding channel for garbage to pass through. The first liquid guide plate for guiding the liquid is fixed to the lower inner end of the first filter plate.
