Description

Technical Field

[0001] This utility model relates to a water purification device for aquaculture ponds. Background Technology

[0002] Patent CN221607905U discloses a pond water purification device for aquaculture, including a mounting frame, a water pump at the top of the mounting frame, a coarse filter box at the top of the mounting frame, a placement rack on the inner wall of the coarse filter box, a blocking mechanism slidably connected to the inner wall of the placement rack, a fine filter box on the right side of the coarse filter box, and a purification box on the right side of the fine filter box. This invention solves the problems of existing pond water purification devices that are prone to clogging during use, where the filter device is easily clogged due to excessive accumulation of impurities, resulting in poor water flow, affecting purification effect and working efficiency. Moreover, it requires regular cleaning and replacement of filter elements and other components, increasing labor and material costs. Furthermore, some purification methods may cause excessive microbial growth, leading to new problems and affecting the effectiveness of use.

[0003] In fact, the most clogged part of the filter is the fine filter box, specifically the connection between the fine filter box and the water pump. The filter element in this location needs to be replaced frequently to avoid clogging. It is worth mentioning that due to the water pump's suction, impurities tend to accumulate more near the water inlet of the filter element, while less in other areas. Replacing the filter element directly in this way would be a waste. Utility Model Content

[0023] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0024] Combination Figure 1-3As shown, a pond water purification device for aquaculture includes a coarse filter box 1 and a water pump 2. A fine filter box 3 is provided between the water pump 2 and the coarse filter box 1. A filter element 4 is rotatably connected inside the fine filter box 3.

[0025] The filter element 4 includes a cylindrical outer shell 5, a connecting shaft 6 in the middle of the outer shell 5, and multiple partitions 7 arranged inside the outer shell 5 with the connecting shaft 6 as the center. Each partition 7 divides the interior of the outer shell 5 into multiple fan-shaped channels, and each fan-shaped channel is provided with a filter layer 8.

[0026] The two ends of the connecting shaft 6 are rotatably connected to the front and rear ends of the fine filter box 3, respectively. The inlet 9 of the water pump 2 is connected to the lower rear end of the fine filter box 3. The lower front end of the fine filter box 3 is connected to the coarse filter box 1 through an opening 10. A fan-shaped channel of the filter element 4 is located between the inlet 9 and the opening 10.

[0027] When the filter layer 8 in a sector channel is filled with impurities, the filter element 4 rotates so that the next sector channel is located between the inlet 9 and the opening 10.

[0028] The working principle of the above structure is as follows: the water to be purified first enters the coarse filter box 1 to filter out large particles of impurities, and then enters the fine filter box 3 through the opening 10. At this time, the water pump 2 draws water, so that the water in the coarse filter box 1 quickly passes through the fan-shaped channel and is drawn out after fine filtration. When the filter layer 8 in the fan-shaped channel in the working state is filled with a lot of impurities, the filter element 4 rotates at the corresponding angle so that the next fan-shaped channel is located between the opening 10 and the water inlet of the water pump 2. This is equivalent to replacing the filter layer 8 between the opening 10 and the water inlet of the water pump 2, which can avoid impurities clogging the filter element 4 and ensure the fine filtration effect.

[0029] The advantages of the above structure are: it is simple to construct, does not require frequent replacement of the filter element 4 of the fine filter box 3, can prevent the filter element 4 from clogging, and ensures the fine filtration effect. Moreover, the filter layer 8 in each sector channel of the filter element 4 is fully utilized.

[0030] Preferred, such as Figure 3 As shown, the partition 7 has six pieces, and the six partitions 7 divide the interior of the outer shell 5 into six fan-shaped channels.

[0031] In another embodiment, such as Figure 1 As shown, a gear ring 11 is provided in the middle of the outer side of the outer shell 5. A motor 12 is fixed on the cover of the top of the fine filter box 3. A transmission gear 13 is fixed on the output shaft of the motor 12. The transmission gear 13 meshes with the gear ring 11. The motor 12 drives the filter element 4 to rotate through the transmission gear 13.

[0032] Specifically, the motor 12 is a stepper motor. Every preset time, the stepper motor 12 drives the filter element 4 to rotate 60° to replace the fan-shaped channel.

[0033] In another embodiment, such as Figure 3 As shown, the outer shell 5 and each partition 7 are also provided with sealing strips at both ends, so that the two ends of each sector channel are sealed to connect the coarse filter box 1 and the water pump 2, so as to prevent the water to be purified from passing directly through the gap between the filter element 4 and the fine filter box 3.

[0034] In another embodiment, such as Figure 1 As shown, the filter layer 8 consists of three sponge layers with increasing density.

[0035] In another embodiment, such as Figure 3 As shown, steel wire mesh is also fixed at both ends of the outer shell 5 to prevent the filter layer 8 from falling out of the filter element 4.

[0036] In another embodiment, combined Figure 1 and Figure 2 As shown, the shape of the opening 10 corresponds to the end of the fan-shaped channel.

[0037] In another embodiment, such as Figure 1 As shown, the coarse filter box 1, the fine filter box 3, and the water pump 2 are arranged in the same tank.

[0038] In another embodiment, combined Figure 1 and Figure 2 As shown, an overflow hole 14 is provided at the front end of the connection between the coarse filter box 1 and the fine filter box 3 to prevent the water to be purified from overflowing directly into the fine filter box 3.
