Harmless resource dry type sanitary tool and method for treating feces or urine

Abstract

The invention relates to a harmless resource dry type sanitary tool and a method for realizing better feces or urine treatment effect. The sanitary tool comprises a fan assembly, a feces and urine separating device, a powder feeding device and a feces and urine treatment device, wherein the feces and urine separating device is arranged under a feces hopper, the powder feeding device is used for respectively feeding powder into the separated feces and urine, the feces and urine treatment device comprises two tank bodies which are used for respectively treating feces or urine, each tank body is provided with a feeding port, an air passage port and a solid discharge port, the feeding port is communicated with the powder feeding device, the air passage port is communicated with the fan assembly, an inner cavity of each tank body is provided with a feces collecting pipe, a retaining plate and a solid and liquid separator, the feces collecting pipe is communicated with the feeding port, the retaining plate is positioned at one side of the air passage port to form a bypass passage, and the fan assembly provides positive pressure for discharging solid matters at the bottom of the tank body. The method comprises the step of mixing the feces or urine with the powder, namely under the action of pneumatic force and self weight, the feces or urine and the powder do reciprocating circulation movement along the bypass passage which is formed by the retaining plate between the feces collecting pipe and the air passage port in each tank body.

Description

technical field [0001] The invention relates to a harmless and resource-based dry sanitary ware, and also relates to a method for treating feces. Background technique [0002] In the patent document CN202604702U, the harmless and resource-based dry sanitary ware developed by our company in the early stage is disclosed. see Figure 11 ~ Figure 12 , which includes a mixing bucket 92 placed below the stool liquid separation device 91, a powder feeding device 93 communicated with the mixing bucket 92, and a manure collecting device. After the feces and powder are mechanically stirred by the stirring blade 921 in the mixing bucket 92, they are The negative pressure fan placed in the manure collection device is directly sucked into the manure collection bag for storage; due to the poor crushing effect of the stirring blade 921, this mechanical stirring method can only produce a superficial mixing effect of the manure and powder, and the manure does not It has been deeply matured,...

AI Technical Summary

Problems solved by technology

see Figure 11 ~ Figure 12 , which includes a mixing bucket 92 placed below the stool liquid separation device 91, a powder feeding device 93 and a manure collecting device communicated with the mixing bucket 92. After the feces and powder are mechanically stirred by the stirring blade 921 in the mixing bucket 92, they are The negative pressure fan placed in the manure collection device is directly sucked into the manure collection bag for storage; due to the poor pulverization effect of the stirring blade 921, this mechanical stirring method can only produce a superficial mixing effect of the manure and powder, and the manure does not It has been deeply matured, so in the existing sanitary ware, the treatment effect on feces is not good;

[0003] Moreover, in the case of a large passenger flow in passenger cars, it is difficult to ensure that no objects that are not easily crushed (such as sanitary napkins) are discarded in the toilet, and the stirring blade 921 is difficult to crush these objects. Once the pipeline is blocked, the urine will stay in the toilet If the powder in the lower part of the powder box is damp, it will cause adverse consequences for the use and management of the bathroom

[0004] In addition, the treatment of feces and urine requires the use of two different powders, requiring two powder boxes, and the overall structure of the sanitary ware is more complicated.
