Description

Technical Field

[0001] This utility model belongs to the field of water purification technology, and specifically relates to a water purification device for fish ponds used in crab seedling farming. Background Technology

[0002] In the process of crab larvae farming, water quality is a key factor determining the survival rate and growth quality. Crab larvae are extremely sensitive to indicators such as dissolved oxygen, ammonia nitrogen content, and pH value in the water. The accumulation of uneaten feed, excrement, and excessive algae growth in fish ponds can easily lead to water quality deterioration, causing diseases and even death. Traditional water exchange methods not only waste water resources but may also disrupt the ecological balance of the aquatic body. Therefore, fish pond water purification devices for crab larvae farming have emerged. This device combines biological purification, physical filtration, and ecological regulation technologies to efficiently remove pollutants from the water, stabilize water quality indicators, create a suitable growth environment for crab larvae, reduce farming costs, and improve farming efficiency, becoming an important supporting equipment for modern crab larvae farming.

[0003] However, existing water purification devices are not very efficient at purifying water and require long operating times. This not only affects the ecological environment of the fishpond but also consumes a lot of resources and increases aquaculture costs due to the long operating time. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a water purification device for crab larvae farming ponds, which improves purification efficiency.

[0005] This utility model is achieved through the following technical solution: A water purification device for crab seedling farming ponds includes a base, a barrel, a barrel cover, an inlet pipe, a water pump, and a filter barrel. The barrel is located in the middle of the base and extends through the main body of the base. The top of the barrel is hinged with a lid, which is connected to a water inlet pipe and a water pump. The bottom of the barrel is an open outlet with several support rods I at the outlet. One end of each support rod I is fixed to the inner wall of the barrel, and the other end is connected to the middle of the outlet. A rotating shaft I is inserted through the intersection of the support rods I. A polygonal connecting block is fixed to the top of the rotating shaft I, and the bottom is connected to the output end of the motor via a coupling. A connecting block is provided in the middle of the bucket lid; The filter barrel is located inside the barrel body; the filter barrel has several drainage holes around its perimeter, and the top of the filter barrel is an open water inlet. Several support rods II are provided at the water inlet. One end of the support rod II is fixed to the inner wall of the filter barrel, and the other end is intersected and connected to the middle of the water inlet; a rotating shaft II is provided through the intersection of the support rods II, and a limiting groove matching the connecting block is fixed at the top of the rotating shaft II; the bottom of the filter barrel is provided with a polygonal connecting groove matching the polygonal connecting block.

[0006] The working principle of this utility model is as follows: In use, the water pump is placed in the fishpond to pump water. The fishpond water enters the barrel through the inlet pipe and flows into the filter barrel through the inlet. Simultaneously, the motor is started, driving the polygonal connecting block to rotate. Due to its own weight, the polygonal connecting groove at the bottom of the filter barrel, which fits onto the polygonal connecting block, is also driven to rotate. The top connecting block of the barrel lid fits onto the limiting groove at the top of the filter barrel, preventing it from detaching from the polygonal connecting block. This allows the motor-driven high-speed rotation of the filter barrel to centrifuge and separate the fishpond water inside. Impurities are trapped in the filter barrel, while the separated water drains through the drain hole, falls to the bottom of the barrel, and exits through the outlet back into the fishpond, thus purifying the water. When too much impurity accumulates in the filter barrel, simply open the lid and lift the filter barrel upwards to separate the polygonal connecting groove from the polygonal connecting block. This allows for easy and quick removal of the filter barrel for cleaning or replacement with a new filter barrel.

[0007] As a further improvement of this utility model, the inner wall of the barrel is provided with several vertically arranged cleaning brushes.

[0008] The cleaning brush can clean the surface of the filter canister, reducing the amount of impurities that overflow from the drain hole and accumulate, clogging the outlet.

[0009] As a further improvement of this utility model, the motor is provided with a waterproof sleeve.

[0010] Installing a waterproof cover on the outside of the motor can prevent purified water from affecting the motor's circuitry and thus avoid accidents.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves the rotation of the filter barrel driven by the motor through the connection of polygonal connecting blocks and polygonal connecting grooves. High-speed centrifugal force is used to separate water and impurities. Water purification can be carried out by directly driving the motor without the need for a long preheating start-up, thereby improving the separation efficiency.

[0012] 2. The filter canister of this new type uses polygonal blocks and corresponding grooves for connection, which facilitates installation and disassembly and provides convenience for cleaning the filter canister later. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings. In the embodiments, unless otherwise specified, the technical means used are all conventional technical means in the art. Example

[0020] like Figure 1-2 The device shown is a water purification device for crab seedling farming ponds, including a base 1, a barrel 2, a barrel cover 3, a water inlet pipe 4, a water pump 5, and a filter barrel 6. The barrel body 2 is located in the middle of the base 1 and extends through the main body of the base 1. A barrel lid 3 is hinged to the top of the barrel body 2, and the barrel lid 3 is connected to a water inlet pipe 4, which is connected to a water pump 5. Figure 3 As shown, the bottom of the barrel 2 is an open water outlet 10. Several support rods I11 are provided at the water outlet 10. One end of the support rod I11 is fixed to the inner wall of the barrel 2, and the other end is connected to the middle of the water outlet 10. A rotating shaft I13 is provided through the intersection of the support rods I11. A polygonal connecting block 14 is fixed to the top of the rotating shaft I13, and the bottom is connected to the output end of the motor 12 through a coupling. like Figure 5 As shown, a connecting block 17 is provided in the middle of the bucket lid 3; The filter bucket 6 is disposed inside the bucket body 2; as Figure 4 As shown, the filter bucket 6 has several drainage holes 7 around its body, and the top of the filter bucket 6 is an open water inlet 18. Several support rods II 19 are provided at the water inlet 18. One end of the support rods II 19 is fixed to the inner wall of the filter bucket 6, and the other end is intersected and connected to the middle of the water inlet 18. A rotating shaft II 20 is provided through the intersection of the support rods II 19. The top of the rotating shaft II 20 is fixed with a limiting groove 16 that matches the connecting block 17. The bottom of the filter bucket 6 is provided with a polygonal connecting groove 15 that matches the polygonal connecting block 14.

[0021] The working principle of this embodiment is as follows: In use, the water pump 5 is placed in the fishpond to pump water. The fishpond water enters the tank 2 through the inlet pipe 4 and flows into the filter canister 16 through the inlet 18. At the same time, the motor 12 is started, driving the polygonal connecting block 14 to rotate. Due to its own weight, the polygonal connecting groove 15 at the bottom of the filter canister 6 is engaged with the polygonal connecting block 14 and rotates. Combined with the limiting groove 16 at the top of the lid 3, the filter canister 6 is limited to prevent it from detaching from the polygonal connecting block 14. This allows the motor 12 to drive the filter canister 6 to rotate at high speed, centrifugally separating the fishpond water inside. The separated impurities are trapped in the filter canister 6, while the separated water is discharged from the drain hole 7, falling to the bottom of the tank 2 and being discharged back into the fishpond through the outlet 10, thus purifying the water. When too much impurity accumulates in the filter canister 6, the lid 3 is opened and the filter canister 6 is lifted upwards to separate the polygonal connecting groove 15 from the polygonal connecting block 14. This allows for a simple and quick removal of the filter canister 6 for cleaning or replacement with a new filter canister 6. Example

[0022] This embodiment is a further improvement based on Embodiment 1, as detailed below: like Figure 2 As shown, the inner wall of the barrel 2 is provided with several vertically arranged cleaning brushes 9.

[0023] The working principle of this embodiment is the same as that of embodiment 1. The cleaning brush 9 can clean the surface of the filter bucket 6, reducing the accumulation of impurities after they overflow from the drain hole 7 and fall down to block the water outlet 10. Example

[0024] This embodiment is a further improvement based on embodiment 2, as detailed below: like Figure 2 As shown, the motor 12 is provided with a waterproof sleeve 21.

[0025] The working principle of this embodiment is the same as that of embodiment 2. Setting a waterproof sleeve 21 on the outside of the motor 12 can prevent the purified water from affecting the circuit of the motor 12 and avoid accidents.
