Problems solved by technology

[0003] At present, there are the following problems in the actual use of the underwater toilet sewage system of the submersible: the underwater toilet sewage system cannot deodorize, the valve life is short, the operation is unreliable, the operation is complicated, the sewage pressure cannot be adjusted according to the outboard water pressure, the sewage discharge effect is poor, and the sewage After being exhausted, high-pressure air is directly injected into the sea water, which will produce whistling and bubbles
The capsule type underwater toilet sewage discharge device of the present invention has the following two difficulties: 1. The repeated deformation of the capsule needs to maintain a relatively high fatigue life to prevent the capsule from breaking; and seawater corrosion

Abstract

The invention discloses a capsule type underwater toilet blowdown device. The device is characterized in that the device includes a sewage inlet pipeline, a storage container, a capsule, a screen bushing, a sewage discharging pipeline and a pump station; the inner cavity of the storage container is provided with the capsule; the two ends of the capsule are sealed and press-fit at the two ends parts of the storage container through an inlet gland and an outlet gland; the inlet gland and the outlet gland are respectively connected to the sewage inlet pipeline and the sewage discharging pipeline;the capsule is provided with the screen bushing, and the two ends of the capsule respectively communicate with the inlet gland and the outlet gland; the pump station is provided with a pipeline whichcommunicates with the storage container; and the sewage inlet pipeline and the sewage discharging pipeline are provided with control valves. Through the utilization of the deformation capabilities ofthe capsule, a hydraulic pump can provide pressure oil to enter the storage container and extrude the capsule to realize the discharging of sewage, the pollution of massive return exhaust gas in a traditional blowdown system on a cabin can be eliminated, and the noise of sewage discharging can be reduced; and the pressure during sewage discharging can be basically stable, so that the device is high in reliability, simple in operation and good in sewage discharging effect.

Description

technical field [0001] The invention relates to a sewage discharge device for absorbing, storing and discharging sewage from an underwater toilet, in particular to a capsule type sewage discharge device for an underwater toilet. Background technique [0002] The toilet sewage discharge device is an essential living facility for underwater submersibles. The toilet sewage discharge device needs to be used frequently, with reliable operation, long service life and low sewage discharge noise. [0003] At present, there are the following problems in the actual use of the underwater toilet sewage system of the submersible: the underwater toilet sewage system cannot deodorize, the valve life is short, the operation is unreliable, the operation is complicated, the sewage pressure cannot be adjusted according to the outboard water pressure, the sewage discharge effect is poor, and the sewage After being exhausted, high-pressure air is directly injected into the seawater, which will p...
