Description

Technical Field

[0001] This application relates to the field of freshwater fish farming pond technology, and in particular to a wastewater treatment device for freshwater fish farming ponds. Background Technology

[0002] Currently, with increasingly stringent pollution and emission controls on freshwater aquaculture, how to treat freshwater aquaculture wastewater and tailwater discharge and reduce its environmental damage has become a crucial issue that aquaculture operators must address.

[0003] In the process of freshwater fish farming, it is necessary to discharge wastewater from the aquaculture ponds and replace it with fresh freshwater. However, if the wastewater is discharged directly without treatment, it may pollute the water source in the discharge area, thus having a negative impact on the environment. This does not meet the requirements of environmental protection. Existing wastewater treatment devices for freshwater fish aquaculture ponds require the filter screen to be disassembled and cleaned after a period of use. However, most wastewater treatment devices currently in use cannot filter and recycle wastewater at the same time as cleaning the filter screen, which reduces the efficiency of wastewater treatment. Utility Model Content

[0004] To address the issue that existing wastewater treatment devices for freshwater fish farming ponds require disassembly and cleaning of the filter screen after a period of use, and that most current wastewater treatment devices cannot simultaneously clean the filter screen and filter and recycle the wastewater, thus reducing the efficiency of wastewater treatment, this application provides a wastewater treatment device for freshwater fish farming ponds.

[0005] The wastewater treatment device for freshwater fish farming ponds provided in this application adopts the following technical solution:

[0006] A wastewater treatment device for freshwater fish farming ponds includes a base. A treatment shell is disposed in the middle of the upper surface of the base, and a first liquid storage structure and a second liquid storage structure are symmetrically arranged on both sides of the treatment shell. An inclined first treatment chamber and a second treatment chamber are opened inside the treatment shell. The first treatment chamber and the second treatment chamber are arranged in a cross shape inside the treatment shell, and a first filter mechanism and a second filter mechanism are detachably installed inside the two chambers respectively. A rotating groove is opened in the middle of the base, and a rotating shaft is fixedly installed at the bottom of the treatment shell. One end of the rotating shaft extends through the rotating groove and a crank handle is fixedly installed thereon.

[0007] Preferably, the first liquid storage structure includes a liquid storage tank, the second liquid storage structure is the same as the first liquid storage structure, two leakage grooves are respectively opened on the side wall of the two sets of liquid storage tanks that are close to each other, and mounting holes are opened on the outer wall of the two sets of liquid storage tanks that are far from each other. The two sets of mounting holes are respectively installed with inlet pipes and outlet pipes, and the inlet pipes and outlet pipes are adapted to the mounting holes.

[0008] Preferably, the first filtration mechanism includes a U-shaped frame that is inserted into the first processing chamber, and guide blocks are symmetrically arranged on both sides of the U-shaped frame. The second filtration mechanism has the same structure as the first filtration mechanism, and the first and second processing chambers are respectively provided with sliding grooves that are adapted to the guide blocks.

[0009] Preferably, a first filter screen and a second filter screen that are adapted to each other are installed in sequence inside the U-shaped frame, and the filter holes of the first filter screen are larger than the filter holes of the second filter screen.

[0010] Preferably, a limiting cylinder is fixedly provided on the outer side of the rotating groove, the rotating shaft passes through the limiting cylinder, and multiple threaded holes are equally spaced on the outer surface. A threaded groove is provided on one side of the limiting cylinder, and a screw matching the threaded hole is installed in the threaded groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This wastewater treatment device for freshwater fish farming ponds allows operators to inject wastewater into the first storage structure. At this time, the first filtration mechanism in the first treatment chamber aligns with both the first and second storage structures. The wastewater inside the first storage structure is then filtered by the first filtration mechanism, and the treated wastewater enters the second storage structure for recycling. After the first filtration mechanism has been used for a period of time, operators can rotate the handle to drive the shaft and treatment housing, causing the treatment housing to rotate between the first and second storage structures. This adjusts the alignment of the second filtration mechanism with both the first and second storage structures. Afterward, operators can disassemble the first filtration mechanism for easy cleaning, ensuring that the wastewater treatment process continues without interruption, thus improving wastewater treatment efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 5 This utility model provides a technical solution:

[0021] A wastewater treatment device for freshwater fish farming ponds includes a base 1, a treatment shell 2 disposed in the middle of the upper surface of the base 1, and a first liquid storage structure 3 and a second liquid storage structure 4 symmetrically disposed on both sides of the treatment shell 2. An inclined first treatment chamber 5 and a second treatment chamber 6 are opened inside the treatment shell 2. The first treatment chamber 5 and the second treatment chamber 6 are arranged in a cross shape inside the treatment shell 2, and a first filter mechanism 7 and a second filter mechanism 8 are detachably installed inside the two. A rotating groove is opened in the middle of the base 1, and a rotating shaft 9 is fixedly installed at the bottom of the treatment shell 2. One end of the rotating shaft 9 extends through the rotating groove and a crank handle 10 is fixedly installed thereon.

[0022] In use, staff can inject wastewater to be treated into the first liquid storage structure 3. At this time, the first filter mechanism 7 in the first treatment chamber 5 is aligned with the first liquid storage structure 3 and the second liquid storage structure 4 respectively. The wastewater inside the first liquid storage structure 3 is filtered by the first filter mechanism 7. The treated wastewater then enters the second liquid storage structure 4 for recycling. After the first filter mechanism 7 has been used for a period of time, staff can turn the handle 10 to drive the rotating shaft 9 and the treatment housing 2 to rotate, so that the treatment housing 2 rotates between the first liquid storage structure 3 and the second liquid storage structure 4, thereby adjusting the second filter mechanism 8 to be aligned with the first liquid storage structure 3 and the second liquid storage structure 4 respectively. After that, staff can disassemble the first filter mechanism 7 for easy cleaning, so as not to affect the wastewater treatment work while cleaning the first filter mechanism 7, thus improving the efficiency of wastewater treatment.

[0023] The first liquid storage structure 3 includes a liquid storage tank. The second liquid storage structure 4 is the same as the first liquid storage structure 3. Two leakage channels 11 are respectively opened on the side wall of the two liquid storage tanks that are close to each other, and mounting holes are opened on the outer wall of the two liquid storage tanks that are far from each other. The two sets of mounting holes are respectively installed with an inlet pipe 12 and an outlet pipe 13. The inlet pipe 12 and the outlet pipe 13 are adapted to the mounting holes. During operation, wastewater is added into the first liquid storage structure 3 through the inlet pipe 12, and the treated wastewater can be discharged through the outlet pipe 13. During treatment, the leakage channel 11 will be aligned with the position of the first filter mechanism 7 or the second filter mechanism 8, and the wastewater will enter the first filter mechanism 7 or the second filter mechanism 8 through the leakage channel 11 for filtration treatment.

[0024] The first filter mechanism 7 includes a U-shaped frame 14 that is inserted into the first processing chamber 5. Guide blocks 15 are symmetrically arranged on both sides of the U-shaped frame 14. The second filter mechanism 8 has the same structure as the first filter mechanism 7. The first processing chamber 5 and the second processing chamber 6 are respectively provided with sliding grooves that are adapted to the guide blocks 15.

[0025] Inside the U-shaped frame 14, a first filter screen 17 and a second filter screen 18 are installed in sequence, with the filter holes of the first filter screen 17 being larger than those of the second filter screen 18.

[0026] By setting guide blocks 15, it is convenient to insert U-shaped frames 14 into the first processing chamber 5 and the second processing chamber 6 after cleaning, and filter the wastewater by setting first filter screen 17 and second filter screen 18.

[0027] A limiting cylinder 19 is fixedly installed on the outside of the rotating groove. The rotating shaft 9 passes through the limiting cylinder 19, and multiple threaded holes 20 are equally spaced on its outer surface. A threaded groove is opened on one side of the limiting cylinder 19, and a screw 21 matching the threaded hole 20 is installed in the threaded groove. In use, when the rotating shaft 9 is rotated to a suitable wastewater treatment position by the crank handle 10, the screw 21 can be rotated to insert into the threaded hole 20, thereby limiting and fixing the position of the rotating shaft 9 and preventing the rotating shaft 9 from shaking during the wastewater treatment process.
