Description

Technical Field

[0001] This utility model belongs to the field of vacuum pump station technology, specifically relating to a marine domestic sewage vacuum pump station with cleaning function. Background Technology

[0002] Freshwater resources are extremely valuable on ships, and shipboard sanitation units typically use vacuum toilets. Vacuum pump stations are crucial components of the vacuum system, responsible for pumping wastewater from these toilets to the wastewater treatment plant. High reliability and convenient maintenance are required for these pump stations. However, due to their operating principle, vacuum pump stations are prone to clogging, making it impossible to establish a vacuum. Clearing these clogging requires contact with wastewater, posing hygiene and safety risks. Utility Model Content

[0003] The purpose of this utility model is to provide a marine sewage vacuum pump station with a cleaning function, so as to solve the problem of hygiene and safety hazards caused by clogging in the existing vacuum pump station mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a marine sewage vacuum pump station with cleaning function, including a vacuum pump having an inlet end and an outlet end; an inlet pipe is connected to the inlet end of the vacuum pump, and a drain pipe is connected to the outlet end; an observation window is provided at the connection between the inlet pipe and the vacuum pump, and an inlet channel is formed between the observation window, the inlet pipe, and the inlet end of the vacuum pump; a flushing hole is provided on the side of the observation window, and a flushing water pipe is inserted into the flushing hole. During use, when the observation window is contaminated and the internal structure cannot be observed, the flushing water pipe can be opened and the vacuum pump can be started to flush the observation window and restore its visibility function without manual disassembly and cleaning. Furthermore, when the valve plate inside the observation window is stuck, the flushing water pipe can be opened and the vacuum pump can be started to flush the valve plate without manual disassembly and cleaning.

[0005] Preferably, the inner wall of the flushing hole facing outward from the observation window has an annular groove, and a sealing assembly is disposed inside the annular groove. The sealing assembly consists of a clamping member and a sealing member, wherein:

[0006] The clamping member is located at the bottom of the inner end of the annular groove and abuts against the outer wall of the flushing water pipe;

[0007] The sealing member is screwed into the annular groove and positioned on top of the clamping member. The sealing member abuts against the outer wall of the flushing water pipe. The sealing member and the clamping member achieve double clamping and sealing of the flushing water pipe. At the same time, the sealing member can also limit the position of the clamping member and force the clamping member to complete the clamping with the flushing water pipe through deformation.

[0008] Preferably, the clamping member includes at least two air bladders, each air bladder partially protruding from the annular groove into the interior of the flushing hole, and the protruding portion of the air bladder abuts against the outer surface of the flushing water pipe, thereby achieving the purpose of clamping.

[0009] Preferably, the sealing component is a rubber ring. The outer surface of the rubber ring and the inner wall of the opening of the ring groove are both threaded and connected by threads. The bottom end face of the rubber ring is separated from the airbag, thereby limiting the airbag and ensuring that the airbag can deform when squeezed by the flushing water pipe. The inner side of the rubber ring is inclined towards the inside of the flushing hole and forms an inclined part that abuts against the flushing water pipe, thereby achieving a tight seal against the flushing water pipe.

[0010] Preferably, the opening of the annular groove expands outwards to form a guide groove, which facilitates the insertion of the flushing water pipe.

[0011] Preferably, a vacuum pressure gauge and a vacuum pressure switch are respectively installed on both sides of the water inlet pipe. The vacuum pressure gauge and vacuum pressure switch are connected to the water inlet channel, and the liquid pressure can be detected by the vacuum pressure gauge and vacuum pressure switch when the liquid enters.

[0012] Preferably, an energy storage tank is provided on the side of the drainage pipe, and the energy storage tank is connected to the drainage pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention allows observation of the internal structure through an observation window. When the observation window of the vacuum pump is contaminated and the internal structure cannot be observed, the flushing water pipe can be opened and the vacuum pump can be started to flush the observation window and restore its visibility function without manual disassembly and cleaning. Furthermore, when the vacuum pump valve plate is stuck, the flushing water pipe can be opened and the vacuum pump can be started to flush the valve plate without manual disassembly and cleaning.
