Description

Technical Field

[0001] The present invention relates to the technical field of ballast water treatment, in particular to a ship ballast water sterilization and algae removal process and a mixing pump thereof. Background Art

[0002] The ballast water system of a ship is used to adjust the ship's draft and the longitudinal and transverse stability and safe metacentric height of the hull, reduce hull deformation to avoid excessive bending moment and shear force, reduce hull vibration, and improve the seaworthiness of empty compartments. During the cross-border voyage of a ship, in order to avoid the invasion of marine species and protect the local water ecological balance, it is usually necessary to sterilize and remove algae from the ship's ballast water. However, the existing ship ballast water sterilization and algae removal treatment process has the following problems when used: Regarding the treatment process of ship ballast water, the existing technology mostly uses electrolysis, ultraviolet rays and ultrasound. This method is not convenient for simple and rapid sterilization and algae removal when treating large-flow ballast water. On the one hand, the cost is high and the installation and use of the entire system are relatively complicated. On the other hand, the service life is short, which increases the maintenance frequency and difficulty. This undoubtedly increases the overall cost and difficulty of use, is not conducive to the development of shipping, and will also cause certain damage to the water body.

[0003] In response to the above problems, it is urgent to carry out innovative designs based on the original ship ballast water treatment. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention breaks through the traditional ballast water treatment process. It uses hypochlorite sensors to sense the ballast water during inlet and outlet, and sterilizes and removes algae by adding oxidants and reducing agents. The overall operation is simple, the equipment cost is low, the maintenance difficulty is low, and the service life is long. Traditional methods such as electrolysis, ultraviolet light, and ultrasound greatly increase the treatment difficulty, shorten the service life, and increase the overall operation and maintenance costs. 2. The present invention utilizes a mixing pump to transport and mix the oxidant and the reducing agent. By arranging the liquid delivery holes on the liquid delivery pipe, multi-area liquid delivery can be performed in the ballast water delivery channel to increase the contact area between the oxidant and the reducing agent and the ballast water, so that the ballast water can be treated in time when it is circulated. Furthermore, the liquid delivery pipe can swing back and forth in the ballast water channel, and the rotation of the liquid delivery pipe improves the treatment efficiency. When adapting to ballast water channels of different specifications, in addition to adjusting the length of the liquid delivery pipe, the swing amplitude of the liquid delivery pipe can also be adjusted synchronously. When used in different scenarios, it can still ensure that the oxidant and the reducing agent are in full contact with the circulating ballast water to avoid omissions in sterilization and algae removal. On this basis, the diameter of the liquid delivery hole on the liquid delivery pipe changes from bottom to top, so that when it swings, the lower liquid delivery hole can provide greater pressure, so that the lower oxidant and reducing agent can be thrown farther. With the swing, horizontal and vertical liquid delivery operations are realized, and the distribution uniformity is increased. The ballast water can be sterilized and algae removed with only simple operations. BRIEF DESCRIPTION OF THE DRAWINGS

A center rod 9 is connected to the top of the impeller 8, a limit rod 10 is fixed to the outside of the center rod 9, and the limit rod 10 is slidably arranged in the limit groove 11, and the limit groove 11 is opened on the inner wall of the liquid delivery pipe 7, and a mounting block 13 is connected to the cavity of the side wall of the mounting frame 4 through a first electric push rod 12, and the mounting block 13 is connected to the outside of the mounting pipe 6 through a shaft; a length adjustment mechanism is provided between the mounting pipe 6 and the liquid delivery pipe 7, and the length adjustment mechanism is used to adjust the extension length of the liquid delivery pipe 7 according to the position of the mounting pipe 6; The liquid feeding mechanism includes a liquid feeding hole 71, which is opened on the outside of the liquid feeding pipe 7, and a sealing ball 72 is connected to the liquid feeding hole 71 through a spring; the liquid feeding hole 71 is designed as a trumpet-shaped structure and is distributed in an equal-angle array on the outside of the liquid feeding pipe 7, and the diameters of the multiple liquid feeding holes 71 increase from bottom to top, and the diameters of the liquid feeding holes 71 increase from outside to inside; the length adjustment mechanism includes a first oil tank 141, and the first oil tank 141 is fixed on the side wall of the mounting tube 6, the outer end of the first oil tank 141 is connected to the first active piston 142 through a spring, and the first oil tank 141 is connected to the first active piston 142 through a spring. A first passive piston 143 is provided at the inner end of the tank 141, and the top of the first passive piston 143 is connected to the bottom of the liquid delivery pipe 7 through a bearing. A first push block 144 is provided at the outer end of the first active piston 142, and the first push block 144 is fixed to the inner wall of the mounting frame 4. The first oil tank 141 is designed as an "L"-shaped structure, and the horizontal width of the first oil tank 141 is greater than the vertical width. The first passive piston 143 is arranged horizontally in the first oil tank 141, and the contact surface of the first push block 144 at the outer end of the first passive piston 143 is designed as a sloped structure. When in use, insert the installation frame 4 into the ballast water delivery channel and perform a sealing treatment. When adding the oxidant and the reducing agent, the motor 2 drives the pump body 3 to run, and the medicine enters the ballast water delivery channel through the transfer pipe 5, the installation pipe 6 and the liquid delivery pipe 7 to treat the ballast water. In this process, the impeller 8 is forced to rotate, and the center rod 9, the limit rod 10 and the liquid delivery pipe 7 are driven to rotate.
