[0024] This application provides a wastewater filtration and purification device for salmon farming, including a purification tank body 1. Inside the purification tank body 1, a filter screen 4, a first activated carbon plate 5, and a second activated carbon plate 6 are movably nested in sequence. The outer wall of the filter screen 4 is fitted with a cleaning component, which facilitates the addition of wastewater purification drugs into the inner cavity between the water inlet pipe 2 and the filter screen 4. Large particulate impurities in the wastewater are filtered through the filter screen 4, and the wastewater is purified by the arrangement of the first activated carbon plate 5 and the second activated carbon plate 6.

[0025] The cleaning component mainly includes a scraper 8, a connecting rod 9 fixedly connected to the outer wall of the scraper 8, a movable block 10 fixedly connected to the top outer wall of the connecting rod 9, and a connecting block 11 fixedly connected to the bottom end of the movable block 10. A groove 12 is provided at the contact part between the filter screen 4 and the movable block 10. A handle 13 is fixedly connected to the top of the connecting block 11, which facilitates pulling the handle 13. With the connection of the movable block 10, the connecting block 11 is driven to slide along the groove 12 opened in the inner wall of the filter screen 4. With the connection of the connecting rod 9, the scraper 8 cleans the impurities attached to the outer wall of the filter screen 4.

[0026] Furthermore, water inlet pipe 2 and water outlet pipe 3 are installed at corresponding positions on both sides of the purification tank body 1, and a sewage discharge pipe 7 is installed on the front of the purification tank body 1. Wastewater flows into the inner cavity of the purification tank body 1 through the water inlet pipe 2, and the purified wastewater is discharged through the water outlet pipe 3.

[0027] Furthermore, the bottom of the inner diameter of the water outlet pipe 3 and the sewage discharge pipe 7 are at the same level as the bottom of the inner wall of the purification tank body 1, which is conducive to the complete discharge of the purified wastewater in the purification tank body 1 through the water outlet pipe 3, and the complete discharge of impurities and sludge in the cavity of the purification tank body 1 through the sewage discharge pipe 7.

[0028] Furthermore, the scraper 8 has a triangular cross-section, and the bottom end of the scraper 8 is attached to the bottom end of the inner wall of the purification tank body 1, which is conducive to the movement of the scraper 8 and cleaning the impurities attached to the outer wall of the filter screen 4.

[0030] Furthermore, the movable block 10 forms a sliding structure with the sliding groove 12 opened on the inner wall of the filter screen 4 through the connecting block 11 and the handle 13. The sliding groove 12 penetrates the inner wall of the filter screen 4, which is conducive to pulling the handle 13 under the connection of the movable block 10, driving the connecting block 11 to slide along the sliding groove 12 opened on the inner wall of the filter screen 4. Under the connection of the connecting rod 9, the scraper 8 is driven to move. When the filter screen 4 is removed from the inner cavity of the purification tank body 1, the cleaning component can be replaced.

[0031] Furthermore, four sets of fixing rods 14 are attached to the outer walls of both ends of the filter screen 4, which helps to limit the position of the filter screen 4 by the four sets of fixing rods 14, making it convenient to replace the filter screen 4.

[0032] Furthermore, four sets of fixing rods 14 are attached to the outer walls of both ends of the first activated carbon plate 5 and the second activated carbon plate 6. This facilitates the use of the four sets of fixing rods 14 to limit the position of the first activated carbon plate 5 and the second activated carbon plate 6, and also makes it convenient to replace the first activated carbon plate 5 and the second activated carbon plate 6.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] Working principle: Wastewater from salmon farming flows into the inner cavity of the purification tank body 1 through the inlet pipe 2.
