Description

Technical Field

[0001] The present invention relates to the technical field of ballast water treatment, and in particular to energy-saving and sterilizing ship ballast water treatment equipment and a treatment method. Background Art

[0002] Ship ballast water, also known as ballast water, refers to the water and suspended matter added to the ship to control the ship's heel, trim, draft, stability or stress. It can be fresh water, seawater, or suspended matter outside the ship. When the ship is unloaded, ballast water can maintain a certain depth of draft to prevent the ship from capsizing; when loaded, by adjusting the ballast water, a certain draft difference or flat draft can be determined to ensure the safe navigation of the ship in a specific water area. In addition, icebreakers can also use ballast water for icebreaking operations. However, the ship's ballast water contains a large number of plankton, microorganisms and bacteria, which will be transmitted to a new geographical environment as the ship sails, which may lead to the invasion of alien species and damage the local ecosystem. Ballast water may even spread viral pathogens, causing damage to the marine ecological environment and human health. Ship ballast water treatment equipment is a marine water treatment equipment, mainly used to treat ship ballast water. When a ship is loading and unloading cargo, draining water, and other operations, the ballast water at the bottom of the ship will be discharged. These wastewaters contain sediments, bacteria, and other substances that pollute the marine environment, so the ship's ballast water needs to be treated to achieve environmental protection purposes.

[0003] After searching, a Chinese patent with announcement number CN220335013U discloses ship ballast water treatment equipment, including: a primary sinking mechanism and a filtering and disinfecting mechanism, characterized in that a water storage tank is arranged on the primary sinking mechanism, and a water injection port, an inclined sieve plate, a mixing device, and a partition plate are arranged in sequence from top to bottom in the water storage tank, the mixing device is rotatably connected to the water storage tank, the bottom of the mixing device is connected to a driving motor, the driving motor is arranged on the lower side of the water storage tank, and a material storage mechanism and a drug injection port are arranged on the axial outer side of the water storage tank; a purification box, an activated carbon adsorption tower, and a disinfection box are connected to the filtering and disinfecting mechanism in sequence, the upper end of the purification box is connected to the bottom of the water storage tank through a drain pipe, and the bottom of the disinfection box is connected with a discharge port.

[0004] Although the ballast water treatment equipment in the above-mentioned prior art can basically meet the use needs during use, it still has the following shortcomings during actual application: first, when treating ballast water, the ballast water is added to the inclined sieve plate in the treatment tank through the water injection port for filtration. Although the subsequent injected water can wash away some impurities filtered out on the inclined sieve plate, when the water injection is stopped, some impurities will still not be washed away. Since the processing capacity of the treatment tank is certain each time, it is necessary to wait until the current sewage is treated before water injection treatment can be carried out again. During this period, some suspended matter will dry up and adhere to the sieve plate, which will gradually reduce the filtration efficiency over time. Secondly, the ballast water is coagulated and separated by adding chemicals and stirring. It is difficult to discharge it completely through the sediment discharge pipe on one side, which is easy to cause residues at the bottom of the inner side of the treatment tank.

[0015] A method for treating ship ballast water with energy saving and sterilization, comprising the following steps:

[0016] S1. First, the ship's ballast sewage is introduced into the treatment tank through the water inlet shell. The sewage is filtered through two filters in the treatment tank. The larger particles of impurities are first filtered out through the upper filter in the treatment tank, and then the smaller particles of impurities in the sewage are filtered out through the lower filter in the treatment tank;

[0017] S2, during filtering, the second drive motor on the right side of the processing box is started, and the fourth bevel gear is driven to rotate through the output end of the second drive motor, and the fourth bevel gear is meshed with the third bevel gear, and the second screw connected to the third bevel gear can rotate in the second mounting groove on one side of the processing box. Due to the rotation of the second screw, the moving rod connected to the outer thread slides, and the scraper connected to the lower end of the moving rod can discharge the impurities filtered out by the filter surface of the filter screen toward the drainage hole at the corresponding moving direction to the processing box for collection;

[0018] S3, the filtered sewage enters the lower part of the treatment box, and then the medicine is added in proportion through the dosing port, and then the stirring motor under the treatment box is started, so that the output end of the stirring motor drives the stirrer to mix the sewage and the medicine to accelerate the separation and sedimentation;

[0019] S4. After sedimentation and separation, the ballast water in the treatment tank is pumped into the purification mechanism along the hose by a water pump. First, the sediment carried in the water flow is filtered out through the ultrafiltration membrane filter chamber, and then the harmful particles carried in the ballast water are adsorbed and filtered through the activated carbon filter chamber. Finally, the ballast water enters the ultraviolet disinfection chamber for disinfection and sterilization, and is discharged from the drain pipe after the treatment is completed;

[0020] S5. When it is necessary to clean the sediment at the bottom of the inner side of the treatment box, the sediment drain pipe on the left side of the treatment box is opened, and then the first driving motor is started. The output end of the first driving motor drives the shaft to rotate in the installation frame, and at the same time, the first bevel gear on the shaft engages with the second bevel gear, and the first screw connected to the second bevel gear can rotate in the first installation groove of the mounting frame. Since the two first screws in the first installation groove run synchronously, the same moving seat connected by the outer thread slides, and a push rod is rotatably installed between the moving seat and the adjustment seat. Through the push rod at one end of the moving seat, the push rod can lift one side of the adjustment seat to a certain height, and the treatment box installed on the adjustment seat is tilted at this time, and the sediment at the bottom of the treatment box can be accelerated on the inclined surface and discharged through the sediment drain pipe;

[0021] S6. While the sedimentation drain pipe is discharging sewage, one end of the flushing pipe is connected to the external water delivery pipe through the connecting port. Water flows through the flushing head on the flushing pipe toward the bottom of the inner side of the treatment box for flushing, and the stubborn sediment at the bottom of the inner side of the treatment box is flushed away through the sedimentation drain pipe.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] First, in the present invention, since the processing box is installed on the adjustment seat, and the adjustment seat rotates on the shaft seat through one side and is placed on the support seat on the other side, the output end of the first driving motor drives the shaft rod to rotate in the installation frame, and at the same time, the first bevel gear on the shaft rod meshes with the second bevel gear, and the first screw connected to the second bevel gear can rotate in the first installation groove of the mounting frame. Since the two first screws in the first installation groove run synchronously, the same moving seat connected by the outer thread slides, and a push rod is rotatably installed between the moving seat and the adjustment seat, and the push rod is pushed through one end of the moving seat so that the push rod can lift one side of the adjustment seat to a certain height, and the processing box installed on the adjustment seat is tilted at this time, so that the sediment at the bottom of the inner side of the processing box can be easily discharged from the sediment discharge pipe;

[0024] Secondly, in the present invention, one end of the flushing pipe is connected to the external water pipe through the connection port, and the water flows through the flushing head on the flushing pipe toward the bottom of the inner side of the treatment box for flushing, and the stubborn sediment at the bottom of the inner side of the treatment box is flushed away through the sediment discharge pipe, thereby facilitating the discharge of the sediment;

[0025] Thirdly, in the present invention, the fourth bevel gear is driven to rotate by the output end of the second driving motor, and at the same time, the fourth bevel gear is engaged with the third bevel gear, and the second screw connected to the third bevel gear can rotate in the second mounting groove on one side of the processing box. The rotation of the second screw causes the moving rod connected to the outer thread to slide, and the scraper connected to the lower end of the moving rod can discharge the impurities filtered out by the filter surface of the filter toward the drain hole at the corresponding moving direction, thereby avoiding the presence of impurities residue on the filter.
