Abstract

Provided is a processing apparatus for quick resource recovery of kitchen garbage, configured as a fully enclosed silo and comprising: a transportation chain configured to drive a charger to lift up and down with a feed port correspondingly disposed above the transportation chain, shredder blades being provided within the feed port to shred materials; a fermentation chamber below the shredder blades, a main stirring shaft being horizontally provided within the fermentation chamber, two secondary stirring wheels being provided on the main stirring shaft at two respective side walls of the fermentation chamber, at the respective side walls the main stirring shaft is connected onto the fermentation chamber the main stirring shaft configured to be rotated in a direction opposite to that of the secondary stirring wheels; the main stirring shaft being provided with stirring paddles; a spiral discharger horizontally provided below the main stirring shaft and provided with a discharge port at one end thereof; a deodorant chamber provided at one side of the feed port, four layers of spaces for placing deodorant fillers therein being arranged within the deodorant chamber, the four layers of deodorant fillers comprising activated carbons, a molecular sieve, a mixture of compost product as well as fungal chaff and lees, and a mixture of wood cuttings and straws in an up-to-down order; the deodorant chamber being provided with an air inlet at its bottom and with an air outlet and a monitor at its top.

First claim

What is claimed is:

1. A processing apparatus for resource recovery of kitchen garbage, configured as a fully enclosed silo and comprising:
a transportation chain configured to drive a charger to lift up and down with a feed port correspondingly disposed above the transportation chain, shredder blades being provided within the feed port to shred materials;
a fermentation chamber below the shredder blades, a main stirring shaft being horizontally provided within the fermentation chamber, two secondary stirring wheels being provided on the main stirring shaft at two respective side walls of the fermentation chamber, at the respective side walls the main stirring shaft is connected onto the fermentation chamber, so as to avoid the materials from being burnt due to over high heating temperature, the main stirring shaft configured to be rotated in a direction opposite to that of the secondary stirring wheels; the main stirring shaft being provided with stirring paddles;
a spiral discharger horizontally provided below the main stirring shaft and provided with a discharge port at one end thereof;
a deodorant chamber provided at one side of the feed port, four layers of spaces which are filled respectively with four layers of deodorant fillers therein being arranged within the deodorant chamber, the four layers of deodorant fillers comprising activated carbons, a molecular sieve, a mixture of compost product as well as fungal chaff and lees, and a mixture of wood cuttings and straws in an up-to-down order; the deodorant chamber being provided with an air inlet at its bottom and with an air outlet and a monitor at its top.

2. The processing apparatus for resource recovery of kitchen garbage according to claim 1 , wherein lift motion of the transportation chain is controlled by the monitor, the feed port is configured to be closed after feeding of the materials is completed, and the shredder blades are driven by a motor which is controlled by the monitor.

3. The processing apparatus for resource recovery of kitchen garbage according to claim 1 , wherein a height of each of respective layers of fillers occupy ⅔ of the corresponding one of respective layers of spaces within the deodorant chamber; and
wherein the compost product, the fungal chaff and the lees are mixed in a volume ratio of 3-4:1-2:1-2.

4. The processing apparatus for resource recovery of kitchen garbage according to claim 1 , wherein a draft fan is provided at the air outlet of the deodorant chamber for drawing off air.

5. The processing apparatus for resource recovery of kitchen garbage according to claim 1 , wherein the stirring paddles are provided with stirring blades.

6. The processing apparatus for resource recovery of kitchen garbage according to claim 1 , wherein materials within the fermentation chamber are pushed and transported to the discharge port by the spiral discharger.
