Description

Technical Field

[0001] The invention relates to the technical field of water treatment equipment, in particular to a multi-layer filter screen aquaculture tail water treatment equipment. Background Art

[0002] Aquaculture produces aquaculture effluent, which usually needs to be treated with designated treatment equipment to treat pollutants in aquaculture. The main pollutants are ammonia nitrogen, nitrite, organic matter, phosphorus and fouling organisms.

[0003] For example, the invention patent with the publication number CN112744985A discloses an inclined aquaculture tailwater treatment system, which includes: a sewage channel for collecting sewage; a fish pond, which is provided with at least one and connected to the sewage channel through a fish pond drainage pipe to form an aquaculture space; a microbial reaction tank, which forms a biological reaction treatment space inside; a microfiltration screen, which is inclined and arranged above the microbial reaction tank for solid-liquid separation; a manure trough, which is arranged below the microfiltration screen for collecting manure; an ecological purification tank, which is used for ecological treatment of sewage; and an overflow water aeration step, which is arranged between the microbial reaction tank and the ecological purification tank for aeration. The system adopts aeration through the overflow water aeration step, which increases the contact area between liquid and air, facilitates aeration, and performs ecological treatment through the ecological purification tank, thus realizing a greening cycle.

[0004] When the above structure is in use, the microfiltration screen has a single structure and cannot perform multi-layer filtration on the aquaculture tail water, which will cause the microfiltration screen to need to be cleaned and replaced frequently. During the cleaning process, the filter plate needs to be disassembled and then manually backwashed with a water gun. Not only is the degree of automation low, but the cleaning efficiency is also low. During the cleaning process of the filter plate, the aquaculture tail water cannot continue to be filtered, which leads to low filtration efficiency of the aquaculture tail water.

[0036] The tail water of aquaculture is introduced into the equipment. The tail water first contacts the top filter screen 5, and the large particles of impurities are initially intercepted. Then the tail water falls to the next filter screen 5, and then finer filtration is performed in turn. The tail water of aquaculture can be filtered in multiple layers, so that the filter screen 5 does not need to be cleaned and replaced frequently.

[0037] When the filter 5 needs to be cleaned, first start the telescopic cylinder, pull the baffle 18 through the push rod, so that the grooves 19 on both sides of the baffle 18 are separated from the side plates, and at the same time, the block 20 is out of contact with the filter 5 frame 4, so that multiple crosses are on both sides of the filter 5, and then start the first motor 6, the first motor 6 drives the drive shaft 7 to rotate, and through the cooperation of the rectangular block and the rectangular groove 9, it can drive the filter 5 frame 4 to rotate around the positioning shaft 8, so that multiple frames 4 drive multiple filters 5 to turn 180 degrees, and then reset the two baffles 18, connect the designated water supply equipment to the transfer pipe on the diverter block 24 through the conduit, remove the cover 31 at the outlet tank 30 and one end of the second empty tank 28, and then take the pull. Plate 29, insert the pull plate 29 into the second empty slot 28, then start the water supply device, so that the cleaning liquid is sprayed at multiple liquid outlets, which can provide a recoil effect to the filter screen 5. At this time, the impurities washed down will fall on the pull plate 29, and then flow out of the liquid outlet slot 30. In this process, start the third motor 26, which can rotate the screw rod 27. Through the effect of the thread structure, the side block 25 can slide along the screw rod 27, so that the vertical pipe 22 can slide in the cavity 21, and then the multiple horizontal pipes 23 can be moved, so that the filter screen 5 can be washed in all directions. The filter plate does not need to be disassembled during the cleaning process, which not only has a high degree of automation, but also has a high cleaning efficiency, thereby improving the filtration efficiency of aquaculture tail water;

[0038] When the filter screen 5 is cleaned, the frame 4 can be turned over again, and then the pull plate 29 is pulled out and the cover plate is fixed;

[0039] Two first empty slots 10 are symmetrically arranged on the workbench 1, and the lower ends of the first side plate 2 and the second side plate 3 are provided with a bottom block 11 that slidably cooperates with the first empty slot 10. The lower end of the workbench 1 is rotatably provided with an annular frame 12 penetrated by a drainage pipe 17, and a gear ring is arranged on the peripheral side of the annular frame 12. A second motor 13 is fixedly arranged at the lower end of the workbench 1, and a gear disk 14 meshing with the gear ring is arranged at the output end of the second motor 13. Two connecting rods 15 are symmetrically arranged at the bottom end of the annular frame 12, and the two ends of the connecting rod 15 are rotatably connected to the annular frame 12 and the bottom block 11, respectively, so that the frame 4 can be easily replaced;

[0040] When the filter 5 needs to be replaced, the two baffles 18 are first moved, and then the second motor 13 is started. The second motor 13 drives the toothed disc 14 to rotate, and the toothed disc 14 drives the annular frame 12 engaged with the gear ring to rotate. The annular frame 12 drives the first side plate 2 and the second side plate 3 to slide synchronously in opposite directions through the connecting rod 15, so that the rectangular block can be disengaged from the rectangular groove 9, thereby facilitating the disassembly of the frame 4 and the filter 5. When installing the frame 4, take the frame 4, place one of the rectangular blocks in the rectangular groove 9, and then support the frame 4 to reset the first side plate 2 and the second side plate 3.
