Kitchen waste treatment device

A kitchen waste treatment device, comprising a main fermentation barrel, a feeding apparatus, a power apparatus, and supporting brackets,

• wherein the main fermentation barrel comprises a barrel body, the barrel body is mounted on the supporting brackets, the barrel body comprises a feed inlet, a discharge outlet and a material chamber, the feed inlet and the discharge outlet communicate with the material chamber, respectively, and a feed end of the feeding apparatus communicates with the feed inlet;
• and the power apparatus is connected to the barrel body in a driving way to drive the barrel body to rotate around its axis;
• the main fermentation barrel further comprises a plurality of push plates, the plurality of push plates are located within the material chamber and fixedly connected to the barrel body, the plurality of push plates are spaced with a set distance, and when the barrel body rotates, the push plates push materials in the material chamber to move along an axial direction of the barrel body;
• the main fermentation barrel further comprises a gas inlet system and a gas exhaust system, the gas inlet system comprising a plurality of gas inlets, the gas exhaust system comprising a plurality of gas exhaust ports, wherein the gas inlets of the gas inlet system and the discharge outlet are located at a same end of the barrel body, and the gas inlets communicate with the material chamber;
• and wherein the gas exhaust ports of the gas exhaust system and the feed inlet are located at a same end of the barrel body, and the gas exhaust ports communicate with the material chamber,
• wherein the main fermentation barrel comprises a first end cover, the first end cover is mounted to cover a barrel opening of the barrel body, wherein the first end cover is configured to rotate in response to rotation of the barrel body, and wherein both the gas exhaust ports of the gas exhaust system and the feed inlet of the barrel body are located on the first end cover;
• wherein the feeding apparatus comprises a supporting plate and a supporting holder, and wherein the power apparatus comprises an electric motor and a gear transmission assembly;
• wherein the plurality of gas exhaust ports are provided uniformly along a circumferential surface of the first end cover;
• and
• wherein each gas exhaust port comprises a gas exhaust channel and a switch, wherein the switch of each gas exhaust port is rotationally connected to the gas exhaust channel of the gas exhaust port such that the switch is configured for rotation between an open state that exposes an opening to the gas exhaust channel and a closed state that closes the opening to the gas exhaust channel, and wherein the switch of each gas exhaust port is configured for rotation about a rotation axis that extends along the axial direction of the barrel body, wherein the switch of each gas exhaust port is configured for rotation to the open state by action of gravity as the first end cover rotates in response to rotation of the barrel body.
