Vacuum toilet dosing system

Abstract

The invention belongs to the technical field of ships, and discloses a vacuum toilet dosing system. The vacuum toilet dosing system comprises a dosing barrel, a medicine conveying pipeline assembly, a dosing pump and a plurality of dosing hoses. The dosing barrel is used for containing liquid medicine; one end of the medicine conveying pipeline assembly is communicated with the dosing barrel, and the medicine conveying pipeline assembly is configured to convey the liquid medicine in the dosing barrel; the dosing pump is used for providing medicine conveying power for the medicine conveying pipeline assembly; one of the ends of the plurality of dosing hoses is communicated with the medicine conveying pipeline assembly, and the other one of the ends of the plurality of dosing hoses is communicated with a black water discharging system of a plurality of sanitary units respectively. According to the vacuum toilet dosing system, the large dosing barrel and the dosing pump are arranged, the dosing pump provides power for sucking the liquid medicine for the medicine conveying pipeline assembly, then the liquid medicine is guided and connected to flow into the black water discharging systems through the multiple dosing hoses, and the purpose of descaling is achieved. The centralized vacuum toilet dosing system is small in occupied space, convenient to arrange, convenient and fast to construct and convenient to maintain daily; the dosing barrel and the dosing pump do not need to be independently arranged for each sanitary unit, and the system is simple, practical and low in input cost.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a vacuum toilet dosing system. Background technique [0002] On ships and offshore platforms, dozens of sanitary units are generally provided on a ship for the living and use of the crew. In order to save water, most sanitary units use vacuum toilet systems. The system is mainly composed of a vacuum pump, drainage pipe and vacuum toilet. Compared with the gravity black water system, the vacuum toilet system can save half of the water and reduce the burden on the domestic sewage treatment device. Therefore, a smaller domestic sewage device can be used to meet the compact Space layout needs. However, as the service life of the ship increases, the black water pipes will become fouled, and in severe cases, the pipelines will be blocked. In order to ensure the smoothness of the pipeline, a dosing pump and a dosing barrel are usually added to the maintenance corner behind each sanitar...

AI Technical Summary

Problems solved by technology

Dosing pumps and dosing barrels need enough space to be placed, but the maintenance corner space of the sanitary unit is narrow, and black and gray water discharge pipes are also arranged, so it is difficult to arrange dosing pumps and dosing barrels

This setting method not only has difficulties in layout, but also needs to purchase multiple sets of dosing pumps and dosing barrels, which is costly and difficult to maintain. There are many positions for regular dosing points, and the daily maintenance cost is high.
