Multi-stage vacuum suction type dejecta collection system and dejecta collection method thereof

Abstract

The invention discloses a multi-stage vacuum suction type dejecta collection system and a dejecta collection method thereof, and relates to the field of feculence disposal. The system comprises a first toilet stool, a second toilet stool and a feculence box. The first toilet stool and the second toilet stool are both connected with the feculence box. A plurality of vacuum units are arranged between the first toilet stool and the feculence box. Each vacuum unit comprises a storage tank and a vacuum generation device. The first toilet stool and the second toilet stool are connected with a control system. According to the system, one or more vacuum units are additionally arranged between the toilet stools and the feculence box for conveying feculences, and direct connection of the two toilet stools and the feculence box is reduced; and when the two toilet stools are simultaneously used, one toilet stool discharges feculences, and the other toilet stool can only wait and discharge feculences after the other toilet stool which discharges feculences firstly completes feculence discharging and the feculence box establishes the vacuum state again, so that the utilization rate of the two toilet stools is increased.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a multi-stage vacuum suction type feces collection system and a feces collection method. Background technique [0002] The feces collection system is an essential sewage treatment system in trains or long-distance buses. The existing treatment method is mainly the first-level vacuum maintenance type, such as figure 1 As shown, the first toilet, the second toilet and the waste tank are connected through the waste discharge valve. When the vacuum state is formed and maintained in the waste tank, if the waste discharge valve of the first closet is opened, the waste in the first closet will be discharged under the action of vacuum. On the contrary, when the drain valve for connecting the second toilet is opened, the dirt in the second toilet is absorbed into the dirt tank, because the first toilet and the second toilet are directly connected to the dirt tank Connected, in order to en...

Problems solved by technology

[0002] The feces collection system is an essential sewage treatment system in trains or long-distance buses. The existing treatment method is mainly the first-level vacuum maintenance type, such as figure 1 As shown, the first toilet, the second toilet and the waste tank are connected through the waste discharge valve. When the vacuum state is formed and maintained in the waste tank, if the waste discharge valve of the first closet is opened, the waste in the first closet will be discharged under the action of vacuum. On the contrary, when the drain valve for connecting the second toilet is opened, the dirt in the second toilet is absorbed into the dirt tank, because the first toilet and the second toilet are directly connected to the dirt tank Connected, in order to ensure that the dirt in the toilet is smoothly sucked into the dirt box through the sewage pipe, the first toilet and the second toilet or other toilets that need to use the vacuum sewage (water) mechanism of the dirt box cannot discharge sewage (water) at the same time, and must wait for one of them After the toilet is drained and a sufficient vacuum is re-established in the dirt box, another toilet or others need to use the vacuum sewage (water) mechanism of the dirt box to discharge the sewage, and the toilet is drained until the dirt box forms a sufficient vacuum. When the bathroom is used, it needs a long waiting time. When the bathroom is used at a peak time, there will be a situation of waiting or delaying work, which will cause inconvenience to users.

In addition, due to space and layout requirements, the sewage pipe between the waste tank and the toilet is long, and the sewage is often blocked in the sewage pipe during sewage discharge
