Description

Technical Field

[0001] The invention relates to the technical field of aquaculture water treatment, and in particular to a water purification, filtering and disinfecting device used for aquaculture. Background Art

[0002] Water purification, filtration and disinfection equipment used in aquaculture is a key equipment to ensure the smooth progress of aquaculture. In the process of aquaculture, the quality of water is crucial. As the aquaculture time goes by, various impurities, leftover bait, feces and metabolites of aquatic organisms will accumulate in the water. If not handled in time, the water quality will deteriorate and affect the healthy growth of aquaculture organisms. This equipment, based on the characteristics of aquaculture water, first purifies the water through a filtration system. Physical filtration methods such as filters and sand filters are used to remove impurities such as solid particles and suspended matter in the water. Next, the disinfection part plays an important role, using safe and effective disinfection methods such as chemical disinfectants and ozone disinfection to kill bacteria, viruses and parasites in the water to prevent the spread of diseases.

[0003] The prior art discloses a water purification device for aquaculture with announcement number CN210825750U. The device uses a first water pump to pump filtered aquaculture water into a disinfection box through a water pipe, opens a valve on a liquid inlet pipe, and adds disinfectant in a disinfectant storage cylinder into the disinfection box. The motor is started, and the motor drives a rotating shaft to rotate. The rotating shaft drives an agitator to fully and evenly mix the disinfectant and aquaculture water to disinfect the aquaculture water.

[0028] like Figure 1-Figure 2As shown, a water purification, filtration and disinfection equipment for aquaculture includes a disinfection box 1. At least one water inlet pipe 11 is arranged at the upper end of the disinfection box 1. The input end of the water inlet pipe 11 is connected to the output end of an aquaculture sewage pump for inputting sewage into the inner side of the disinfection box 1. A water outlet part 12 is arranged at the inner lower end of the disinfection box 1. The water outlet part 12 is arranged in a funnel shape, so that the filtered and disinfected water is discharged from the water outlet part 12 for recycling.

[0029] like Figure 2 As shown, a filtering mechanism 2 is installed in the middle of the upper end of the disinfection box 1, and the filtering mechanism 2 includes a private service motor 21. The driving end of the private service motor 21 passes through the middle of the upper end of the disinfection box 1 and is fixedly installed with a transmission rod 22. A filter barrel 23 is arranged on the outside of the transmission rod 22. The filter barrel 23 is in a barrel-shaped arrangement with an open upper end and a closed lower end, and a filtering hole is opened on the arc surface of the filter barrel 23. The lower end of the transmission rod 22 passes through the filter barrel 23, and a secondary filter cartridge 24 is fixedly installed on the lower end of the transmission rod 22. The secondary filter cartridge 24 has the same structural composition as the filter barrel 23, and the upper ends are both rotatably connected to the inner side of the disinfection box 1. The aperture of the filter hole of the secondary filter cartridge 24 is smaller than the aperture of the filter hole of the filter barrel 23. The private service motor 21 drives the transmission rod 22 forward or reversely, so that the secondary filter cartridge 24 and the filter barrel 23 rotate to generate centrifugal force, thereby allowing the sewage to pass through the filter hole to achieve sewage filtering.

[0030] like Figure 2-Figure 6 As shown, a disinfection mechanism is installed at the upper end of the disinfection box 1, and the disinfection mechanism is composed of a disinfection storage disk 3, a transmission assembly 4, a drainage member 5 and a diversion disk 6.

[0031] The disinfection storage disk 3 includes an upper cover 31, a connecting pipe 32 is installed at the upper end of the upper cover 31, a liquid storage bin 33 is threadedly provided at the lower end of the upper cover 31, through holes 331 are symmetrically opened at the bottom of the inner side of the liquid storage bin 33, and a blocking component 34 is fixedly installed on the inner side of the upper cover 31 located at the upper end of the through hole 331;

[0032] A transmission assembly 4 is installed on the disinfection box 1 located at the lower side of the disinfection storage disk 3. The transmission assembly 4 includes a driven gear 41. A driving gear 211 is installed between the private service motor 21 and the transmission rod 22. The driven gear 41 is meshed and connected with the driving gear 211. A center column 42 is fixedly installed on the upper end of the driven gear 41. A transmission belt 43 is sleeved on the outer side of the center column 42, and the upper end of the center column 42 is movably connected to the lower side of the liquid storage bin 33. A rotating column 44 is arranged on the inner side of one end of the transmission belt 43 away from the center column 42, and the upper end of the rotating column 44 is movably connected to the lower side of the liquid storage bin 33.

[0033] A drainage member 5 is provided on the middle thread of the rotating column 44, and the drainage member 5 includes a drainage tube 51 and an extrusion sheet 52 installed at the lower end of the drainage tube 51. A diverter plate 6 is sleeved on the outside of the disinfection box 1, and the extrusion sheet 52 matches the inner side of the diverter plate 6.

A water absorbent member 62 is provided on the inner side of the diverter plate 6, and the water absorbent member 62 is a component made of sponge material.

[0034] Specifically, when the private service motor 21 drives the transmission rod 22 in the forward direction, it also drives the driving gear 211 to drive the driven gear 41 to rotate. The driven gear 41 drives the rotating column 44 to rotate through the transmission belt 43. The rotating column 44 then drives the drainage tube 51 to move downward. The drainage tube 51 then pushes the extrusion sheet 52 to squeeze the water absorbing part 62. The disinfectant absorbed by the water absorbing part 62 overflows from the overflow hole 61 to the inner wall of the disinfection box 1. At this time, the sewage droplets thrown out contact and mix with the overflowed disinfectant and flow to the lower side of the disinfection box, thereby completing the mixing of the sewage and the disinfectant in the form of water drops.

[0035] like Figure 4-Figure 6 As shown, a water inlet hole 512 is also opened on the outer side of the upper end of the drainage tube 51, and the blocking component 34 includes a support column 341, a return spring 342 is fixedly installed on the inner side of the support column 341, and a blocking column 343 is fixedly installed on one end of the return spring 342, the blocking column 343 matches the through hole 331, and the blocking column 343 abuts against one end face of the drainage tube 51 close to the water inlet hole 512.

[0036] Specifically, when the private service motor 21 drives the transmission rod 22 in reverse, the rotating column 44 drives the drainage tube 51 to move upward, and then the drainage tube 51 pushes the blocking column 343 to move upward, and then the water inlet hole 512 is inserted into the disinfectant and connected thereto. At this time, the disinfectant enters the drainage tube 51 from the water inlet hole 512, and enters the inner side of the diversion plate 6 through the drainage tube 51 and is absorbed by the water absorbent 62, thereby completing the fluid replenishment.

[0037] like Figure 1-Figure 2 and Figure 7-Figure 8As shown, the disinfection box 1 is provided with an anti-blocking component 7, which includes an impurity collecting box 71, a dust suction motor 72 is installed at the upper end of the impurity collecting box 71, a main pipe 73 is installed at the input end of the dust suction motor 72, an upper dust suction pipe 74 is installed at the upper end of the main pipe 73, the impurity suction end of the upper dust suction pipe 74 is in contact with the inner wall of the filter barrel 23, a lower dust suction pipe 75 is installed in the middle of the main pipe 73, the impurity suction end of the lower dust suction pipe 75 is in contact with the inner wall of the secondary filter cartridge 24, the upper dust suction pipe 74 and the lower dust suction pipe 75 have the same structural composition, the upper dust suction pipe 74 includes an auxiliary pipe 741 and a suction pipe 742 installed at one end of the auxiliary pipe 741, the other end of the auxiliary pipe 741 is connected to the main pipe 73, the suction pipe 742 is arranged in a duckbill shape when viewed from above, and the duckbill suction end of the suction pipe 742 is in contact with the inner wall of the upper dust suction pipe 74.

[0038] Specifically, during the centrifugal filtration process of the secondary filter cartridge 24 and the filter barrel 23, impurities will accumulate on the inner walls of the secondary filter cartridge 24 and the filter barrel 23. After being used for a period of time, the water replenishment can be stopped. At this time, the dust suction motor 72 is started to make the main pipe 73 generate strong suction, and at the same time rotate the secondary filter cartridge 24 and the filter barrel 23. The impurities accumulated on the inner walls of the secondary filter cartridge 24 and the filter barrel 23 are sucked into the impurity collection box 71 by the suction pipe 742 through the auxiliary pipe 741, completing the anti-blocking treatment, which is convenient for the long-term and efficient use of the device.
