Description

Technical Field

[0001] The invention relates to a domestic waste treatment device, in particular to a treatment device for making domestic waste into fertilizer. Background Art

[0002] Currently, the use of microbial fermentation technology is a developing field. By applying various microorganisms in the fermentation chamber, various types of kitchen waste and organic matter can be degraded and reduced to obtain organic fertilizer with soil improvement effect.

[0003] The principles of fertilizer production from domestic waste can be roughly divided into two types: anaerobic fermentation and aerobic fermentation. Anaerobic fermentation is a process that reduces or completely isolates waste from air contact, uses anaerobic bacteria to decompose organic matter, and produces carbon dioxide, water, methane, and humus soil; aerobic fermentation is a method of turning the pile, forcing ventilation, and using aerobic bacteria to decompose organic matter and stabilize it. The products are carbon dioxide, water, and humus soil. Since aerobic fermentation fertilizer production has high yield, good fertilizer quality, and no secondary pollution, aerobic fermentation is mostly used for fertilization. However, existing domestic waste treatment equipment still has some shortcomings during use: domestic waste often contains liquid, and the liquid enters the fermentation bin along with the domestic waste, which will affect the efficiency of waste fermentation. Therefore, it is very necessary to discharge the liquid in the domestic waste before fermentation. Summary of the invention

[0024] (I) In the present application, when filtering is performed in the solid-liquid separation box, the stepper motor works and drives the Z-axis screw to rotate, the linear moving block drives the guide shaft to move downward, and then the extrusion plate pushes the domestic garbage on the compression plate downward to squeeze out the liquid in the domestic garbage. When the compression plate is continuously pressed downward by the extrusion plate, the rotating shaft rotates, causing the compression plate to tilt and swing downward, and then during the filter pressing process, the domestic garbage can be pushed to the second conveying pipe, so that the processed domestic garbage falls into the fermentation box, and the force storage torsion spring enables the compression plate to swing back during the pressure reduction process, preparing for the next filter pressing.

[0026] (III) In the present application, domestic garbage is put into the feed trough, and the driving motor is operated so that the driving shaft drives the spiral feed blade to rotate, so as to continuously convey the domestic garbage in the garbage conveyor to the right, and enter the separation trough in the solid-liquid separation box. During the conveying, the liquid in the garbage can enter the first conveying pipe through the leakage hole, and then enter the fermentation box for crushing. The size of the leakage hole is larger than the hole size of the bottom filter, so that most of the liquid can be discharged in advance during the conveying process of the domestic garbage, and the garbage mixed in the liquid can be subsequently crushed, and finally the liquid is finally discharged through the liquid separation filter, so that the solid-liquid separation effect of the domestic garbage is better.

[0027] (IV) In the present application, when the driving motor is working, due to the transmission of the same-direction sprocket and the transmission chain, the driving shaft and one of the driven shafts will rotate at the same time, and under the meshing transmission of the two counter-gears, the two driven shafts will rotate at the same time, and the rotation directions are opposite. Then the crushing roller crushes the domestic waste entering the fermentation box to improve the dispersion and prepare for fermentation and fertilizer production; due to the meshing of the lower gear and one of the counter-gears, the stirring rod drives the mixing blades to rotate in the fermentation box and stir the domestic waste while crushing, so that the fermentation is more complete.
