Description

Technical Field

[0001] This utility model relates to the technical field of aquaculture wastewater recycling equipment, specifically a wastewater filtration device for aquaculture. Background Technology

[0002] Aquaculture wastewater refers to water bodies containing large amounts of organic matter, nutrients, ammonia nitrogen, nitrite, nitrate, phosphorus, and solid waste generated during the aquaculture of aquatic organisms such as fish, shrimp, and shellfish. If this wastewater is discharged directly into natural water bodies without treatment, it will cause problems such as eutrophication, water quality deterioration, and algal blooms.

[0003] When recycling and filtering wastewater from aquaculture, most systems use filter screens to first remove solid impurities before further purification. However, in current wastewater filtration devices, when wastewater is discharged into the filter box, it often concentrates on impacting a specific area of ​​the filter screen. This area of ​​the filter screen is subjected to prolonged impact from the wastewater and the heavy pressure of accumulated filtered waste, which can accelerate deformation and damage, thus affecting the lifespan of the filter screen.

[0004] Therefore, we propose to design a wastewater filtration device for aquaculture. Utility Model Content

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-3 This utility model provides a wastewater filtration device for aquaculture, including a base 1, with columns 2 fixedly connected to the four corners of the top of the base 1, a filter box 3 fixedly connected to the top of the columns 2, drain valves 4 on both sides of the filter box 3, and a hydraulic rod 5 fixedly connected to the center of the top of the base 1. The telescopic end of the hydraulic rod 5 passes through the filter box 3 and is equipped with a filter assembly 6.

[0025] The filter assembly 6 includes a filter frame 601, with reinforced steel columns 11 embedded and fixedly connected on both sides of the filter frame 601, which facilitates the improvement of the structural strength of the outer frame of the filter screen 604.

[0026] In this embodiment, handles 12 are fixedly connected to both ends of the top of the filter frame 601, and slots 13 that fit the handles 12 are provided at both ends of the bottom of the filter frame 601. The slots 13 are designed to facilitate the stacking of multiple filter frames 601, while the handles 12 facilitate the removal of the top filter frame 601 by the staff for cleaning.

[0027] The filter frame 601 has two rectangular slots 602 inside. A support plate 603 is fixedly connected to the center of the inner wall of each rectangular slot 602. A filter screen 604 is fixedly connected to the top of the inner wall of the rectangular slot 602.

[0028] The top of the telescopic end of the hydraulic rod 5 is fixedly connected to a magnet, and a groove 7 corresponding to the telescopic end of the hydraulic rod 5 is opened at the center of the bottom of the filter frame 601. An iron piece 8 corresponding to the magnet is fixedly connected to the top of the groove 7, so that the telescopic end of the hydraulic rod 5 can be inserted into the groove 7 and the hydraulic rod 5 can be connected to the filter frame 601.

[0029] Meanwhile, limit blocks 9 are fixedly connected to both sides of the filter frame 601, and limit grooves 10 are opened on both sides of the inner wall of the filter box 3. The limit blocks 9 and the limit grooves 10 are slidably connected to each other, which facilitates the installation of the filter frame 601 in the filter box 3.

[0030] The top of the support plate 603 fits into the bottom of the filter screen 604, which facilitates the support of the filter screen 604, reduces the impact on the filter screen 604 when sewage enters the filter box 3, and improves the service life of the filter screen 604.

[0031] When in use, first connect the hydraulic rod 5 to the external oil pump and discharge the wastewater from the aquaculture pond into the filter box 3. In the initial state, multiple filter frames 601 are stacked at the bottom of the filter box 3.

[0032] Because the filter frame 601 has a support plate 603 inside that can support the top of the filter screen 604, the filter screen 604 will not deform under any impact when sewage falls into the filter box 3, thus effectively improving the service life of the filter screen 604.

[0033] After the wastewater is completely discharged into the filter box 3, the hydraulic rod 5 is activated to lift the filter frame 601. During this period, solid impurities in the wastewater are filtered by the filter screen 604 and remain on the top of the filter screen 604. As the filter frame 601 rises, the wastewater passes through the filter screen 604 evenly, avoiding the wastewater from concentrating on a part of the filter screen 604. This allows the entire filter screen 604 to perform filtration, preventing over-filtration in some areas and premature damage to that part of the filter screen 604.

[0034] At the same time, the large-area filter screen 604 allows impurities to accumulate on the top of the filter screen 604 while reducing the impact of waste material clogging the filter screen 604. Since the wastewater is evenly distributed on the top of the filter screen 604 and begins filtration simultaneously, the filtration efficiency of the wastewater is guaranteed.

[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
