Embodiment 1

[0044] This embodiment provides a ship sewage storage device, such as Figure 1 ~ Figure 3 As shown, the sewage storage device includes a mounting frame 1, a first box body 2, a second box body 3, a liquid level gauge 19, a pulverizing circulation pump 6, an internal circulation pipeline, a cutting sewage pump 10, a sewage pipeline, and a first shut-off valve 12. The second stop valve 13 and the third stop valve 24.

[0045] In this example, a water inlet 4 and an air hole 5 are provided on the top of the first box body 2 . The water inlet 4 is used to communicate with the sewage pipe network on the ship and the inner cavity of the first box body 2. The air hole 5 is used to balance the air pressure in the first box body 2 and the second box body 3. When the first box body 2 and the second box body 3 receive sewage, the gas in the inner cavity is discharged along the air hole 5. When the first box body 2 and the second box 3 are blowing down, outside air enters along the air...

Embodiment 2

[0068] This embodiment provides a shore-based sewage suction device, such as Figure 5 As shown, the device includes a housing 61 , a hose 62 , a retractable reel, a drive mechanism for the retractable pipe, a self-priming pump 39 , a flow meter 55 , and a fourth cut-off valve 40 .

[0069] The inside of the housing 61 is provided with a supporting mechanism; the hose 62 is used to connect the sewage pipeline of the sewage storage device in the ship; the front end of the hose 62 is provided with a quick connector 63 connected to the end of the sewage pipeline.

[0070] Such as Figure 6 and Figure 7 As shown, the take-up reel includes a drum 31, a left baffle 32, a right baffle 33 and connecting bearings. The drum 31 contains an inner cavity, and one end of the drum 31 is sealed; the left baffle 32 and the right baffle 33 are sleeved on the outer wall of the drum 31, and the outside of the drum 31 between the left baffle 32 and the right baffle 33 is soft. The winding area...

Embodiment 3

[0092] Such as Figure 11 As shown, a kind of automatic control method of ship sewage storage device is provided in this example, and this method is applied in the ship sewage storage device described in embodiment 1; Automatic control method comprises the steps:

[0093] S1: In the initial state, the first box 2 and the second box 3 are empty, the first controller 15 in the control box controls the first shut-off valve 12 to be in the open state, the second shut-off valve 13 and the third shut-off valve 24 is in a closed state, and makes the crushing circulation pump 6 and the cutting sewage pump 10 in a shutdown state;

[0094] S2: The first controller 15 controls the opening of the second shut-off valve 13, the sewage storage device starts to collect the sewage inflowing from the sewage pipe network in the ship, and the gas analyzer 22 monitors the inside of the first box 2 and the second box 3 in real time The concentration of the gas produced by fermentation in the cavit...

Abstract

The invention discloses a sewage suction device capable of automatically winding and unwinding a pipeline. The sewage suction device comprises a shell, a hose, a winding and unwinding drum, a pipe winding and unwinding driving mechanism and a self-priming pump. A supporting mechanism is arranged in the shell; the hose is used for connecting a sewage discharge pipeline of a sewage storage device in a ship; the front end of the hose is provided with a quick connector connected with the end of the sewage discharge pipeline. The winding and unwinding drum comprises a rotating drum, a left baffle and a right baffle; the pipe winding and unwinding driving mechanism comprises a rotating shaft, a single-rotation reciprocating lead screw, a limiting pulley block, a motor and a transmission mechanism; a limiting pulley block is used for limiting the moving direction of the hose during winding and unwinding; a reciprocating lead screw is used for driving the limiting pulley block to reciprocate in the axial direction of a screw rod in the reciprocating lead screw; a transmission mechanism is used for enabling an output shaft of the motor to simultaneously drive the reciprocating lead screw and the drum to rotate; the hose in the suction device can be automatically wound through related mechanisms, so that the workload of operators is greatly reduced.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a sewage suction device capable of automatically retracting and releasing pipes. Background technique [0002] During the operation of the ship, a large amount of domestic sewage and waste materials will be generated, including sewage and waste materials generated during the cleaning process of personnel or objects, sewage and waste materials generated during the cooking process, and excrement generated during the excretion process of personnel, etc. These pollutants usually flow into domestic sewage storage tanks through the ship's sewage system. Since it is usually impossible to carry out harmless treatment on the ship for daily needs, the ship usually discharges the pollutants in the domestic sewage storage tank after the replenishment is docked; Extract and transfer. [0003] Most of the existing ship sewage storage tanks are simple in structure, and are only used ...
