Description

Technical Field

[0001] This utility model belongs to the field of aquarium technology, and specifically relates to a circulating water purification device for fish farming. Background Technology

[0002] When keeping ornamental fish in aquariums or fish farms, it is necessary to filter the water to ensure a good living environment for the fish.

[0003] Patent application CN202222991529.7 discloses a fish tank filter for convenient water filtration in aquariums. The fish tank filter includes a tank body, a sedimentation tank, a first inclined guide plate, a dry / wet separation chamber, a filter sponge, a drip / rain chamber, a drip plate, a biochemical chamber, a second inclined guide plate, a drain hole, a water inlet, a guide hole, and a water storage tank. The sedimentation tank is integrally fixed to one side of the tank body, and the top of the sedimentation tank has a water inlet. When using the fish tank filter provided by this invention, dirty water from the aquarium flows into the sedimentation tank, where it remains at the bottom. The first inclined guide plate obstructs the water flow, allowing most of the fish waste to accumulate and settle at the bottom of the sedimentation tank. With prolonged sedimentation, the user only needs to periodically open the drain pipe to remove the fish waste from the bottom of the sedimentation tank, making cleaning convenient.

[0004] However, the bottom of the above-mentioned aquarium filter tank is flat, and the filtered impurities sink to the bottom, making them difficult to drain and potentially clogging the filter screen. Utility Model Content

[0005] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a circulating water purification device for fish farming that facilitates the discharge of impurities.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A circulating water purification device for fish farming includes a plurality of filter boxes, a digestive bacteria box, and an oxygenation box arranged in sequence; filter plates are provided between adjacent filter boxes and between the final filter box and the digestive bacteria box, and the filter plates are provided with a plurality of filter holes; digestive bacteria units are provided in the digestive bacteria box, and an oxygenation structure is provided in the oxygenation box; the lower parts of the plurality of filter boxes, the digestive bacteria box, and the oxygenation box are all in the shape of a polygonal pyramid; the bottom of the digestive bacteria box and the plurality of filter boxes are provided with sludge discharge ports, and the bottom of the oxygenation box is provided with a drain outlet.

[0008] This invention comprises several filter boxes that can perform step-by-step filtration of water used for fish farming, with filtered impurities periodically discharged through the sludge discharge port. The digestive bacteria unit can digest toxic substances produced from ammonia nitrogen and nitrite in fish waste into harmless substances. The digestive bacteria can convert nitrite into nitrate, which provides nutrients to the water. When water flows from a height over the aeration structure, it increases the oxygen content in the water. This invention can thoroughly filter water, convert nitrite, and increase oxygen levels, ensuring that the water is fully purified during the circulation process and improving the aquatic environment.

[0009] Several filter boxes, digester boxes, and aerator boxes have a multi-faceted pyramidal lower section, with the sludge discharge port located at the apex of the pyramid. Impurities inside the box can slide down the sloping surfaces from all directions to the sludge discharge port. When the sludge discharge port is opened, impurities inside the box can be fully discharged, preventing secondary pollution of the water by deposited impurities. The multi-faceted pyramidal lower section of the aerator box allows for the complete discharge of fully treated water, which is then returned to the fish tank or aquaculture area through the drain outlet.

[0010] In a preferred embodiment of this invention, the diameter of the filter holes on several filter plates decreases sequentially from the direction closest to the digester bacteria chamber. The filter holes are used to filter impurities such as fish feces; the sequentially decreasing diameter of the filter holes on several filter plates allows the water to be filtered in stages. The number of filter chambers can be four to six, and the diameter of the filter holes on the filter plates is 1–6 mm.

[0011] As a preferred embodiment of this invention, both ends of the filter hole are provided with flared openings. After filtration, impurities can slide off the conical surface of the flared openings, preventing them from clogging the filter holes.

[0012] In a preferred embodiment of this invention, a sealing plug is fitted onto the slag discharge port; a valve is connected to the drain outlet. During water circulation, the sealing plug seals the slag discharge port tightly, and the valve at the drain outlet opens, connecting to the fish tank or aquaculture area. After water circulation is complete, the sealing plug is removed, and impurities from several filter boxes and digestive bacteria boxes are discharged from the slag discharge port.

[0013] In a preferred embodiment of this invention, a slot is provided between adjacent filter boxes, and the filter plate is inserted into the slot. The filter plate can be removed from the slot for easy replacement or cleaning.

[0014] As a preferred embodiment of this invention, a baffle plate is provided inside the digestive bacteria tank, and water passage holes are provided at the bottom of the baffle plate. The digestive bacteria unit is located on the side of the baffle plate away from the filter plate. Water that has passed through the final filter plate enters the digestive bacteria tank and is blocked by the baffle plate, allowing water to enter the area where the digestive bacteria unit is located only through the water passage holes at the bottom of the baffle plate. Thus, the water passes through the digestive bacteria unit from bottom to top, ensuring full contact between the water and the digestive bacteria unit and improving the treatment effect.

[0015] In a preferred embodiment of this invention, the digestive bacteria unit includes a feeding cage placed inside a digestive bacteria tank, containing several digestive bacteria stones. The digestive bacteria stones contain digestive bacteria. When water passes through the digestive bacteria unit, the unit digests the toxic substances produced by ammonia nitrogen and nitrite in fish waste into harmless substances. The digestive bacteria also convert nitrite into nitrate, which provides nutrients to the water. Digestive bacteria are bacteria that require very high oxygen levels, and the increased oxygen levels in the water as it passes through the filter holes on the filter plates provide a suitable environment for their survival.

[0016] As a preferred embodiment of this utility model, a partition is provided between the digestive bacteria tank and the oxygenation tank, and an overflow pipe is connected to the upper part of the partition. The overflow pipe is located on the upper side of the oxygenation structure. The overflow pipe is connected to the upper part of the partition, so that water can flow from a higher position to the oxygenation structure, thereby increasing the oxygen content of the water under the impact.

[0017] As a preferred embodiment of this invention, the oxygenation structure comprises several layers of steel mesh, with supporting columns connecting adjacent steel meshes. As water successively impacts the multiple layers of steel mesh, the water gradually becomes oxygenated, ensuring that the oxygen content of the water meets the requirements.

[0018] In a preferred embodiment of this invention, a first support platform for supporting the digestive bacteria unit is fixed inside the digestive bacteria chamber; a second support platform for supporting the oxygenation structure is fixed inside the oxygenation chamber. The first support platform supports the digestive bacteria unit, which can be removed from the nitrifying bacteria chamber for easy replacement or cleaning. The second support platform supports the oxygenation structure, which can be removed from the oxygenation chamber for easy replacement or cleaning.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model comprises several filter boxes that can perform step-by-step filtration of water used for fish farming, with filtered impurities periodically discharged through the sludge discharge port. The digestive bacteria unit can digest toxic substances produced by ammonia nitrogen and nitrite in fish waste into harmless substances. The digestive bacteria can convert nitrite into nitrate, which provides nutrients to the water. When water flows from a height over the aeration structure, it increases the oxygen content in the water. This utility model can thoroughly filter water, convert nitrite, and increase oxygen in the water, ensuring that the water is fully purified during the circulation process and improving the aquatic environment.

[0021] 2. The lower part of several filter boxes, digestive bacteria boxes and oxygenation boxes of this utility model are all multi-faceted pyramids, so that the slag discharge port is located at the tip of the multi-faceted pyramid. Impurities in the box can slide down from the inclined surfaces in all directions to the slag discharge port. When the slag discharge port is opened, the impurities in the box can be fully discharged, avoiding secondary pollution of the water by the deposited impurities. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other.

[0031] like Figures 1-6As shown, the fish farming circulating water purification device of this embodiment includes a plurality of filter boxes 1, a digestive bacteria box 2, and an oxygenation box 3 arranged in sequence; filter plates 4 are provided between adjacent filter boxes 1 and between the final filter box 1 and the digestive bacteria box 2, and the filter plates 4 are provided with a plurality of filter holes 41; digestive bacteria units 5 are provided in the digestive bacteria box 2, and an oxygenation structure 6 is provided in the oxygenation box 3; the lower part of the plurality of filter boxes 1, digestive bacteria box 2, and oxygenation box 3 are all in the shape of a polygonal pyramid 7; the bottom of the digestive bacteria box 2 and the plurality of filter boxes 1 are provided with a slag discharge port 71, and the bottom of the oxygenation box 3 is provided with a drain outlet 72.

[0032] The present invention comprises several filter boxes 1 that can perform step-by-step filtration of water used for fish farming, with filtered impurities periodically discharged through the sludge discharge port 71. The digestive bacteria unit 5 can digest toxic substances produced by ammonia nitrogen and nitrite in fish waste into harmless substances. The digestive bacteria can convert nitrite into nitrate, which provides nutrients to the water. When water flows from a height over the aeration structure 6, it increases the oxygen content in the water. This invention can thoroughly filter water, convert nitrite, and increase oxygen levels, ensuring that the water is fully purified during the circulation process and improving the aquatic environment.

[0033] Among them, the multi-faceted pyramid 7 is a square pyramid, that is, the lower part of several filter boxes 1, digestive bacteria boxes 2 and oxygenation boxes 3 are all spliced ​​together by four inclined plates, so that the lower ends of each box are gathered at one end, and a slag discharge port 71 or a drain port 72 is provided. Impurities can smoothly slide down from the inclined surface to the slag discharge port 71, avoiding impurity residue.

[0034] The lower parts of several filter boxes 1, digestive bacteria boxes 2, and oxygenation boxes 3 are all shaped like polygonal pyramids 7, with the sludge discharge port 71 located at the apex of the pyramid 7. Impurities inside the boxes can slide down from the inclined surfaces in all directions to the sludge discharge port 71. When the sludge discharge port 71 is opened, the impurities inside the boxes can be fully discharged, preventing secondary pollution of the water by deposited impurities. The polygonal pyramid 7 at the bottom of the oxygenation box 3 allows for the full discharge of the fully treated water, which is then discharged back into the fish tank or aquaculture area through the drain port 72.

[0035] It should be noted that, from the direction closest to the digester bacteria tank 2, the diameter of the filter holes 41 on the filter plates 4 decreases sequentially. The filter holes 41 are used to filter impurities such as fish feces. The successive decrease in the diameter of the filter holes 41 on the filter plates 4 allows the water to be filtered in stages. The number of filter tanks 1 can be set to four to six, and the diameter of the filter holes 41 on the filter plates 4 is 1 to 6 mm.

[0036] To prevent the filter holes 41 from clogging, both ends of the filter holes 41 are provided with flared openings. After the water is filtered, impurities can slide off from the conical surface of the flared openings, preventing impurities from clogging the filter holes 41.

[0037] A sealing plug 73 is plugged into the slag discharge port 71; a valve 74 is connected to the drain port 72. During the water circulation process, the sealing plug 73 seals the slag discharge port 71 tightly, and the valve 74 of the drain port 72 opens and connects to the fish tank or aquaculture area. After the water circulation process is completed, the sealing plug 73 is removed, and impurities in several filter boxes 1 and digestive bacteria boxes 2 are discharged from the slag discharge port 71.

[0038] A slot 11 is provided between adjacent filter boxes 1, and the filter plate 4 is inserted into the slot 11. The filter plate 4 can be removed from the slot 11 for easy replacement or cleaning.

[0039] To ensure that water fully passes through the digestive bacteria unit 5, a baffle plate 8 is installed inside the digestive bacteria tank 2. The baffle plate 8 has water passage holes 81 at its bottom. The digestive bacteria unit 5 is located on the side of the baffle plate 8 away from the filter plate 4. Water that has passed through the final filter plate 4 enters the digestive bacteria tank 2 and is blocked by the baffle plate 8. Water can only enter the area where the digestive bacteria unit 5 is located within the digestive bacteria tank 2 through the water passage holes 81 at the bottom of the baffle plate 8. Thus, the water passes through the digestive bacteria unit 5 from bottom to top, ensuring full contact between the water and the digestive bacteria unit 5 and improving the treatment effect.

[0040] Specifically, the digestive bacteria unit 5 includes a feeding cage 51, which is placed inside the digestive bacteria tank 2. Several digestive bacteria stones 52 are placed inside the feeding cage 51. The digestive bacteria stones 52 contain digestive bacteria. When water passes through the digestive bacteria unit 5, the unit digests the toxic substances produced by ammonia nitrogen and nitrite in fish waste into harmless substances. The digestive bacteria convert nitrite into nitrate, which provides nutrients to the water. Digestive bacteria are bacteria that require very high oxygen levels. When water passes through the filter holes 41 on the filter plates 4, the oxygen content in the water increases, providing a suitable environment for the digestive bacteria to survive.

[0041] To ensure that the water fully impacts the oxygenation structure 6, a partition 9 is installed between the digestive bacteria tank 2 and the oxygenation tank 3. An overflow pipe 91 is connected to the upper part of the partition 9, and the overflow pipe 91 is located on the upper side of the oxygenation structure 6. The overflow pipe 91 is connected to the upper part of the partition 9, so that the water can flow from a higher position to the oxygenation structure 6, thereby increasing the oxygen content of the water under the impact.

[0042] Specifically, the oxygenation structure 6 includes several layers of steel mesh 61, with supporting columns 62 connecting adjacent steel meshes 61. As water successively impacts the multiple layers of steel mesh 61, the water gradually becomes oxygenated, ensuring that the oxygen content of the water meets the requirements.

[0043] Furthermore, a first support platform 21 for supporting the digestive bacteria unit 5 is fixed inside the digestive bacteria chamber 2; a second support platform 31 for supporting the oxygenation structure 6 is fixed inside the oxygenation chamber 3. The first support platform 21 supports the digestive bacteria unit 5, which can be removed from the nitrifying bacteria chamber for easy replacement or cleaning. The second support platform supports the oxygenation structure 6, which can be removed from the oxygenation chamber 3 for easy replacement or cleaning.

[0044] The manufacturing process of the circulating water purification device in this embodiment is as follows:

[0045] The first production method:

[0046] The main body of the device is formed by vacuum adsorption; the filter holes 41 on the filter plate 4 are pressed out by a custom mold of the injection molding machine; the feeding cage 51 of the digestive bacteria unit 5 can also be made by vacuum forming.

[0047] There are two forms of oxygenation structure 6. One is to make three layers of steel mesh 61 made of stainless steel and then weld them to oxygenation box 3. The other is to make three layers of steel mesh 61 made of stainless steel and then connect the partition steel mesh 61 with support columns 62 and place the oxygenation structure 6 inside oxygenation box 3.

[0048] The second method of production:

[0049] The entire circulating water purification device is manufactured using a custom injection molding machine mold.

[0050] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
