Suction-type dejectas collecting system

Abstract

The invention discloses a suction-type dejectas collecting system. A first toilet stool and a second toilet stool are arranged on a vacuum sewage tank, wherein one of the first toilet stool and the second toilet stool is directly connected with the vacuum sewage tank; the other one of the first toilet stool and the second toilet stool is connected with the vacuum sewage tank through a vacuum sewage storage device; when sewage exists in the other one of the first toilet stool and the second toilet stool, a sewage drain valve connected with the other one of the first toilet stool and the second toilet stool is opened, and sewage is sucked into the vacuum sewage storage device; when the sewage suction frequency or volume of the vacuum sewage storage device reaches a set value, a sewage drain valve, connected with the vacuum sewage tank, of the vacuum sewage storage device is opened, the sewage in the vacuum sewage storage device is sucked into the vacuum sewage tank under a vacuum effect of the vacuum sewage tank; and before the sewage suction frequency or volume of the vacuum sewage storage device reaches the set value, the toilet stool directly connected with the vacuum sewage tank singly uses the vacuum sewage tank. The use frequency of the vacuum sewage tank is reduced and conflicts, which are caused when the plurality of toilet stools share the vacuum sewage tank, are avoided.

Description

Technical field [0001] The invention relates to a feces collection system for trains or long-distance passenger cars, in particular to a suction type feces collection system. Background technique [0002] At present, the treatment method of the sewage treatment system in trains or long-distance passenger cars is mainly the first-level vacuum holding type, such as figure 1 As shown, the toilet 101 and the toilet 102 are directly connected to the dirt tank 103 through a drain valve. When a vacuum state is formed and maintained in the dirt tank 103, if the drain valve of the toilet 101 is opened, the dirt in the toilet 101 is in the vacuum. Under the action, it is adsorbed into the dirt tank 103. On the contrary, when the drain valve for connecting the toilet 102 is opened, the dirt in the toilet 102 is adsorbed into the dirt tank 103, because the toilet 101 and the toilet 102 are directly connected to the dirt tank 103. Connected, in order to ensure that the dirt in the toilet 101 ...

Problems solved by technology

[0002] At present, the treatment method of the sewage treatment system in the train or long-distance bus is mainly the first-level vacuum maintenance type, such as figure 1 As shown, the toilet 101 and the toilet 102 are directly connected with the dirt tank 103 through the drain valve. When a vacuum is formed and maintained in the dirt tank 103, if the drain valve of the toilet 101 is opened, the dirt in the toilet 101 will be in a vacuum. Under the action, be adsorbed in the dirt box 103, otherwise, when the toilet 102 is connected with the sewage valve to open, the dirt in the toilet 102 is adsorbed in the dirt box 103, because the toilet 101, the toilet 102 are all directly connected with the dirt box 103 Connected, in order to ensure that the dirt in the toilet 101 and the toilet 102 is successfully sucked into the dirt tank 103 through the sewage pipe, the toilet 101, the toilet 102 or other vacuum drainage (water) mechanisms that need to use the dirt tank cannot discharge sewage (water) at the same time , must wait for one of the closets to finish blowing down, after the dirt box 103 has re-established a sufficient vacuum, another closet or others need to use the vacuum blowdown (water) mechanism of the dirt box to carry out blowdown, and the closet blowdown is completed until the sewage When the box 103 forms a sufficient vacuum degree, 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, causing inconvenience to users

In addition, due to space and layout requirements, the sewage pipeline between the dirt box 103 and the closet is relatively long, and the dirt is often blocked in the sewage pipeline during sewage discharge.
