Description

Technical Field

[0001] The utility model relates to the technical field of breeding, in particular to a drawer-type multifunctional and efficient water quality biochemical filter. Background Art

[0002] At present, small and medium-sized aquariums mainly use three types of filtration: top filtration, wall filtration or bottom filtration to achieve the purpose of filtering impurities and harmful substances in the water.

[0003] The main principle of these three types of filtration is to first filter out large particles of impurities in the water through physical filtration (such as filter cotton, filter cloth and other physical filtration materials), and then use biochemical filtration (such as bacterial houses, ceramic rings, biochemical cotton and other bacterial attachment carriers) to treat the main harmful chemicals in the water - ammonia nitrogen (ammonia nitrogen refers to combined nitrogen in the form of ammonia or ammonium ions, that is, nitrogen in the water in the form of free ammonia (NH3) and ammonium ions (NH4)). Among them, biochemical filtration is the most critical.

[0004] Ammonia nitrogen in the aquarium is the main toxic substance in the water and also the most toxic substance. The lethal concentration of free ammonia (NH3) to fish is 0.2-2.0 mg / L. When it is less than 0.2 mg / L, it will cause chronic lesions in the internal organs of fish and cause damage to the surface tissues. Ammonia nitrogen in the aquarium mainly comes from fish excrement, food residues and decomposed organic matter. Biochemical filtration mainly decomposes ammonia nitrogen in the water into nitrite and nitrate through the nitrification of nitrifying bacteria, greatly reducing the content of ammonia nitrogen in the water. At the same time, the final product of nitrification, nitrate, has low toxicity and can be absorbed by plants, and will not pose a major threat to fish in the water.

[0005] There are three key points in the process of nitrifying bacteria producing nitrification: 1. Nitrifying bacteria cannot tolerate polluting organic matter such as feces, and must be intercepted by pre-physical filtration to ensure their activity; 2. Nitrification is an oxygen-consuming process. The higher the oxygen content, the faster the reaction rate. 3. Nitrifying bacteria need a porous structure as their attachment carrier. Only when nitrifying bacteria are in an attached state can they play a nitrifying role. They cannot play a role in a free state.

[0006] There are some existing products on the market for the three types of filtration: top filtration, wall filtration, and bottom filtration, and they all have some shortcomings to a greater or lesser extent. The main products of top filtration are turnover boxes and drip boxes. They have high filtration efficiency, but they are too large and need to occupy the upper space of the fish tank, which is very unsightly and easy to generate noise; common products of wall filtration include back filter fish tanks, wall-mounted waterfall filters, etc. Their disadvantages are small internal space, low filter material carrying capacity, and low upper limit of filtration capacity; common products of bottom filtration include filter cartridges and bottom filter tanks. The designs of both are not easy to clean and maintain, and their functions are relatively simple. Utility Model Content

DETAILED DESCRIPTION

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] like Figure 1 to Figure 5 As shown, the drawer-type multifunctional and efficient water quality biochemical filter of the utility model includes four parts, namely a sedimentation bin 1, a rain drawer bin 2, a multifunctional water storage bin 3 and a water supply pipeline 4; the components can be increased or decreased according to demand, and it is generally used with the mainstream overflow fish tank 5 on the market.

[0032] Among them, the rain shower drawer 2 is installed on the top of the multifunctional water storage tank 3, and the sedimentation tank 1 is located on one side of the multifunctional water storage tank 3. The multifunctional water storage tank 3 is connected to the water inlet of the fish tank 5 through the water supply pipe 4 to input filtered water into the fish tank. The water outlet of the fish tank 5 is connected to the sedimentation tank 1 through the water supply pipe. The circulating water passes through the sedimentation tank 1, the rain shower drawer 2, the multifunctional water storage tank 3 and the water supply pipe 4 in sequence to purify and filter the water quality.

[0033] Specifically, Figure 2As shown, the sedimentation tank 1 is an independent water storage box, which is flat, high, and has a certain width, and a large water storage capacity. The water flow area of ​​the sedimentation tank 1 is provided with a vertical baffle 13, a step plate 16, and a horizontal baffle 11; the bottom of the vertical baffle 13 and the step plate 16 form a narrow channel 1, and one end of the horizontal baffle 11 and the vertical baffle 13 form a narrow channel 2, so that the water flow slows down when passing through this place, and large particles of pollutants will settle under the action of gravity.

[0034] The horizontal baffle 11 can prevent large particles of pollutants from moving upward with the water flow. At the same time, two inclined sliding plates 12 are provided under the horizontal baffle 11, respectively located under narrow channel 1 and narrow channel 2, which can ensure that large particles of pollutants are concentrated at the sewage outlet 14 at one end of the step plate 16 after sedimentation, which is convenient for cleaning and maintenance.

[0035] The main function of the sedimentation tank 1 is to precipitate large particles of pollutants and reduce water flow noise. If there is no sedimentation tank, large particles of pollutants can only be intercepted by subsequent filter cotton. If too much pollutants accumulate on the filter cotton, it will rot and pollute the water quality, and it will cause clogging of the filter cotton and reduce the filtration efficiency. In order to ensure the filtration efficiency of the filter cotton, the filter cotton without a sedimentation tank must be cleaned frequently. After a sedimentation in the sedimentation tank, the frequency of cleaning the filter cotton can be greatly extended, reducing the pressure of filter maintenance. This is very useful when raising medium and large fish such as koi, arowana, tiger fish, etc. If only small fish are raised, this area can be changed to a simple water backpack (detachable external water tank) to reduce the overall cost and difficulty of production.

[0036] like Figure 3 , Figure 4 As shown, the shower drawer compartment 2 includes a shower board 21, a plurality of drawer-type shower boxes 22 and a rectangular box. The top of the rectangular box is open, and the shower board 21 is horizontally laid on the upper end of the rectangular box; the front side of the rectangular box is equipped with a plurality of openings for installing the drawer-type shower boxes 22, and the rectangular box is also equipped with a horizontal guide rail 23 for facilitating the horizontal movement of the drawer-type shower boxes 22. The difference between the shower board 21 and the drawer-type shower box 22 and ordinary flat panels and drawers is that there is a hole structure at the bottom, and the size and number of the holes are designed according to the water flow rate.

[0037] The water in the fish tank flows out of the sedimentation bin from the outlet 15 of the sedimentation bin and reaches the shower plate 21, and flows out from the small holes on the shower plate and falls into the drawer-type shower box 22. The drawer-type shower box 22 can be designed into different multi-columns and multi-layers according to needs. The upper drawer-type shower box is paved with filter cotton to intercept large particles of pollutants and form a dry-wet separation box. The lower drawer-type shower box contains biochemical filter materials to form a biochemical filter box; nitrifying bacteria attached to the biochemical filter materials treat toxic substances in the water. During maintenance, you only need to pull out the drawer to complete the maintenance of the filter cotton or biochemical filter material. The water flowing down from the rainforest box eventually falls into the water trough and flows into the multi-functional water storage tank from the circular hole 24 of the water trough.

[0038] The purpose of the rain shower drawer is to efficiently complete physical filtration and biochemical filtration. Traditional bottom filter designs often cannot achieve dry-wet separation in physical filtration. The filter cotton is generally soaked in water, and the pollutants intercepted by the filter cotton are soaked in water for a long time. After a long time, they will become corrupt and pollute the water quality again. The drawer-type rainforest box can not only achieve dry-wet separation, but also can be directly pulled out and the filter cotton can be replaced, which is relatively easy to maintain. In addition, the drawer-type rain shower box can complete biochemical filtration more efficiently than the traditional bottom filter cylinder. As mentioned above, nitrification is an oxygen-consuming process, and the filter material in the drawer-type rain shower box can directly contact the air, greatly improving the gas exchange efficiency.

[0039] Experiments have shown that rain filtration can achieve or even exceed the biochemical filtration effect of traditional bottom filter tanks while using less filter material. In addition, after the bacteria attached to the biochemical filter material die, they will block the pores of the biochemical filter material. The bacterial film and the bodies of dead bacteria will also pollute the water quality during the decay process. It is very inconvenient to clean the filter tank of the traditional bottom filter, and when the filter material is taken out of the bottom of the tank for cleaning, the stirring of the water flow in the bottom tank can easily cause a large number of bacteria to die, causing the biochemical filtration system to collapse.

[0040] The drawer-type shower box can be taken out to maintain the filter material according to the needs, which is simple and easy to operate. And maintaining one box at a time and maintaining in batches will not affect other filter materials, nor will it affect the overall digestive system, which is more conducive to the smooth operation of the system. The circular hole 24 of the water accumulation tank can be used to place filter bags, and the filter bags can be placed with functional filter materials such as fine-mesh filters, activated carbon or yin and yang resins according to needs. Although traditional bottom filters can also be used to place functional filter materials, the water flow in the bottom tank is not fixed, and the water flow does not necessarily flow through the functional filter material placement position, resulting in great uncertainty in the use effect of the functional filter material. The circular hole for hanging the filter bag in the water accumulation tank can force all water to flow through the circular hole and flow through the functional filter material placement area, greatly improving the use efficiency of the functional filter material.

[0041] like Figure 4As shown, the multifunctional water storage bin 3 is located below the shower drawer bin 2 and is a rectangular water trough, and the multifunctional water storage bin 3 shares the left side panel, the right side panel and the rear side panel with the rectangular box body of the shower drawer bin 2; at the same time, the front side panel of the multifunctional water storage bin 3 protrudes from the front side panel of the shower drawer bin 2 by a certain distance, ensuring that the overflowing water can be caught during the normal operation of the shower drawer bin 2 or when the drawer-type shower box 22 is replaced to prevent it from falling to the ground.

[0042] The water filtered by the rain shower drawer can flow into the multifunctional water storage tank. The main function of the multifunctional water storage tank 3 is to place a water pump to pump the water in the filter back into the fish tank. In addition, it can also perform other practical functions.

[0043] 1. Thick sand filtration function: Sand can be spread in the water storage layer, with a thickness of 7-14cm, to simulate the anaerobic environment in nature for anaerobic bacteria to colonize. As mentioned earlier, through the filtration of the sedimentation tank and the rain drawer tank, the ammonia nitrogen in the water has been converted into nitrates with lower toxicity. At this time, the nitrates still have a certain toxicity and can only be removed by changing water or plant absorption during normal aquarium farming. Changing water is time-consuming and labor-intensive, and aquatic plant farming is very troublesome. It is easy to die and rot, and it cannot coexist with certain fish. Denitrifying bacteria are mostly anaerobic bacteria, and in nature they are mainly colonized in the silt of ponds. Spreading sand in the water storage layer to cultivate anaerobic denitrifying bacteria does not require maintenance and is closer to natural conditions;

[0044] 2. Quarantine and isolation function: New fish often contain some pathogens, such as parasites or fungi, after being brought home. In addition, the fish raised in the main tank may also be infected due to seasonal changes, food spoilage, etc. If the sick fish mentioned above are left in the main tank, it is easy to cause group infection and lead to serious consequences. If a separate fish tank is prepared for epidemic prevention, it will not only be inconvenient to manage, but also easily cause fish stress and will be idle afterwards. Place the sick fish in a multi-functional water storage tank for isolation, and install an ultraviolet sterilization lamp in the water supply pipeline, so that the sick fish can be raised in the original tank and water, which can minimize the risk of stress, save energy, and protect the health of the fish in the main tank.

[0045] 3. Equipment placement function: Aquariums often need to be equipped with many necessary fish life-support devices, such as heating rods, oxygen pumps, etc., which are not beautiful if placed in the main tank. Since the water storage layer and the main tank share the same water body and are always in circulation, most of the life-support equipment required by fish can be placed in the multi-functional water storage tank to enhance the aesthetics of the main tank.

[0046] The water supply pipe 4 can be connected to the water pump and the water inlet of the main cylinder with a hose or a plastic hard pipe, and the bottom of the water supply pipe 4 is connected to the water pipe interface 31 on the side panel of the multifunctional water storage tank 3. The core component is an "n" type pipeline structure, the pipeline is thicker in the middle, and the length and diameter are designed according to the water flow rate. There is a pipeline inlet and outlet on the upper and lower sides of the pipeline, which can be used to connect the water pipe. One or more waterproof joints can be set at the upper end of the thick pipe, and equipment such as a heating rod, an ultraviolet sterilization lamp, and a gas refiner can be inserted.

[0047] The core components of the water supply pipe 4 can be used for multiple functions and purposes. Inserting a heating rod can be used to stabilize the water temperature of the fish tank and enhance the aesthetics of the main tank; inserting an ultraviolet sterilization lamp can be used to prevent algae from growing in the water and kill pathogens in the water; inserting a gas refiner can be used to refine CO2, which is convenient for users who raise aquatic plants.

[0048] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
