technical field

The invention relates to a sanitary facility, in particular to an integrated intelligent environment-friendly toilet with vacuum manure suction and fermentation.

Background technique

As a common sanitary facility, the performance of toilets directly affects people's quality of life. At present, the common flushing toilets have the following disadvantages:

(1) The traditional sanitary ware adopts the water flushing type, and the odor will still remain in the air, which cannot solve the odor problem of the bathroom with small space and poor air flow;

(2) The traditional sanitary ware adopts the flushing type, and the traditional water-saving toilet stipulated by the state is 6L/time, which wastes a lot of water resources and cannot save energy and protect the environment;

(3) The traditional sanitary ware adopts the water flushing type, which mainly relies on the gravity of the water to flush the feces, so the pipeline direction should be up and down as much as possible and the underground pipe network needs to be buried, which is relatively limited;

(4) The traditional sanitary ware adopts the water flushing type. When the water volume is relatively low, it is easy to cause blockage and affect the stability of operation;

The power supply voltage is AC 220V; the heating method is electric heating plate heating, and the control temperature can be arbitrarily set within the adjustment range; the environment in the equipment space is heated by air convection, and the temperature is maintained above 0 degrees to ensure a closed pressure water tank and vacuum The piping box in the tank and fermentation equipment space will not freeze, the temperature distribution is uniform, and the temperature rise effect is fast. Use the temperature sensor to detect the temperature information in the equipment space and convert it into an electrical signal and send it to the PLC controller. When the temperature is lower than the set value, the heating plate starts to heat, and when the temperature reaches the set value, the heating plate stops working. The intelligent antifreeze system works intermittently and has good power saving. According to the humidity detected by the humidity sensor in the fermentation box, it is judged whether the fermentation is completed. After the fermentation is completed, the PLC controller starts the lifting device to transport the solid organic fertilizer. Preferably, the lifting device model is MCST-150.
