Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture, and in particular relates to a high-efficiency dissolved oxygen fine filtering device used in aquaculture. Background Art

[0002] With the rapid development of aquaculture, how to improve water quality, especially the dissolved oxygen level in water, has become an important factor limiting the improvement of aquaculture production and quality. Traditional water treatment methods focus on single filtration or oxygenation, which is difficult to effectively solve the dual needs of water purification and dissolved oxygen improvement at the same time.

[0003] In the prior art, physical filtration or chemical treatment is generally used to remove suspended matter and some harmful substances in water, but these methods often cannot completely improve water quality, especially the effect of increasing the dissolved oxygen content in water is limited. In addition, although conventional oxygenation equipment can increase the dissolved oxygen level in water, it often ignores the purification of the water itself during the oxygenation process, making it difficult to purify the water and increase the dissolved oxygen simultaneously. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a high-efficiency dissolved oxygen fine filtration equipment used in aquaculture, which can not only effectively filter and remove impurities in water, but also significantly increase the dissolved oxygen content in water.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A high-efficiency dissolved oxygen fine filtration device used in aquaculture, comprising a coarse filtration bin, an input pipe fitting is arranged on the top of the coarse filtration bin, and a coarse filtration component is arranged inside the coarse filtration bin, and the coarse filtration component is located below the input pipe fitting;

[0007] The coarse filter assembly includes a filter cover, which is arranged in a trumpet shape, and a sewage pipe is inserted at the bottom of the filter cover, and the sewage pipe runs through the side wall of the coarse filter bin;

[0008] A bottom bin is arranged at the bottom of the coarse filter bin, and a filter plate, a bracket and an aeration plate are arranged in sequence from top to bottom inside the bottom bin, and an output pipe is fixedly connected to the outer side surface of the bottom bin.

[0009] Furthermore, the input pipe fitting comprises a main pipe, the bottom of the main pipe is symmetrically fixedly connected with a column, the bottom of the column is fixedly connected with a diverter, and the shape of the diverter is set to be an inverted trumpet shape.

[0010] Furthermore, a bin cover is provided on the top of the coarse filter bin, and the bin cover is arranged in a ring shape, and the bin cover is sleeved on the main pipeline.

[0011] Furthermore, the inner side wall of the coarse filter assembly is fixedly connected with flow blocking grooves at equal intervals along the height direction thereof, and the shape of the flow blocking grooves is set to be annular.

[0012] Furthermore, filtering holes are evenly provided between adjacent baffle grooves.

[0013] Furthermore, a plug-in tube is fixedly connected to the bottom end of the filter cover, and the plug-in tube is inserted into one end of the sewage pipe.

[0014] Furthermore, atomizing heads are evenly distributed on the top of the aeration plate, and an air inlet pipe is fixedly connected to one side of the aeration plate.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] Through the use of the coarse filter bin and the coarse filter assembly, large suspended solids and some harmful substances in the aquaculture water are effectively removed, and the water quality is preliminarily improved. This directly responds to the shortcomings of the existing water treatment technology mentioned in the background technology in terms of high efficiency and simultaneous treatment of large amounts of water and accurate removal of impurities. The design of the fine filtration equipment enables it to effectively remove suspended solids and harmful substances in the water without reducing the treatment rate, thereby creating a healthier and more suitable growth environment for aquaculture.

[0017] The trumpet-shaped design of the filter cover and the setting of the sewage pipe not only further improve the filtering efficiency, but also can discharge the filtered impurities in time, avoiding the accumulation of impurities in the filtering system and extending the service life of the filtering system.

[0018] The setting of the aeration plate and the design of the atomizer head significantly increase the dissolved oxygen content in the water. The gas is refined into tiny bubbles by the atomizer head, which increases the distribution area of ​​the bubbles in the water, thereby improving the dissolution efficiency of oxygen. This design directly solves the problem of low dissolved oxygen content in aquaculture water mentioned in the background technology, provides sufficient dissolved oxygen for aquatic organisms, and promotes their healthy growth. At the same time, the combination of the high-efficiency filtration and dissolved oxygen functions of the equipment realizes the simultaneous purification of water quality and improvement of dissolved oxygen, fully meets the dual requirements of aquaculture for water quality and dissolved oxygen levels, and provides strong support for the sustainable development of the aquaculture industry.

[0030] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0031] See also Figure 1-5 , a high-efficiency dissolved oxygen fine filtration device used in aquaculture, comprising a coarse filtration bin 1, an input pipe 2 is arranged on the top of the coarse filtration bin 1, and a coarse filtration component 3 is arranged inside the coarse filtration bin 1. The coarse filtration component 3 is located below the input pipe 2; in aquaculture, improving the dissolved oxygen level in the water and removing impurities in the water are the keys to improving the aquaculture efficiency. Through the design of the coarse filtration bin 1, the device effectively realizes the preliminary filtration of the aquaculture water body to remove large suspended matter and some harmful substances, creating conditions for subsequent fine filtration and dissolved oxygen treatment.

[0032] The coarse filter assembly 3 includes a filter cover 31, which is arranged in a trumpet shape, and a drain pipe 32 is inserted at the bottom of the filter cover 31, and the drain pipe 32 runs through the side wall of the coarse filter bin 1; the trumpet-shaped design of the filter cover 31 helps to expand the contact area between the water flow and the filter medium, thereby improving the filtering efficiency. The design of the drain pipe 32 enables the filtered impurities to be discharged in time, keeps the filter assembly clean, and prolongs its service life.

[0033] The bottom of the coarse filter bin 1 is provided with a bottom bin 4, and the inside of the bottom bin 4 is provided with a filter disc 5, a bracket 6 and an aeration disc 7 from top to bottom, and an output pipe 41 is fixedly connected to the outer surface of the bottom bin 4; the filter disc 5 further refines the impurity filtration in the water body, and the bracket 6 provides a stable support structure for the filter disc 5 and the aeration disc 7. The aeration disc 7 is efficiently oxygenated through the atomizing head 71 to ensure that the dissolved oxygen content in the aquaculture water is in an ideal state.

[0034] See also Figure 2 The input pipe fitting 2 includes a main pipe 21, a column 211 is symmetrically fixedly connected to the bottom of the main pipe 21, and a diverter 22 is fixedly connected to the bottom of the column 211. The shape of the diverter 22 is set to be an inverted trumpet shape; this design effectively disperses the water flow entering the coarse filter bin 1, ensures that the water flow passes through the filter cover 31 evenly, and improves the filtering efficiency.

[0035] See also Figure 1-2 A bin cover 11 is provided on the top of the coarse filter bin 1, and the shape of the bin cover 11 is set to be annular, and the bin cover 11 is sleeved on the main pipeline 21; the design of the bin cover 11 is convenient for opening and closing the device, and is convenient for daily maintenance and overhaul.

[0036] See also Figure 3-4 The inner wall of the coarse filter component 3 is fixedly connected with baffle grooves 311 at equal intervals along its height direction, and the shape of the baffle grooves 311 is set to be annular; the baffle grooves 311 further enhance the filtering effect by slowing down the water flow speed, ensuring that impurities are effectively intercepted.

[0037] See also Figure 3 , filter holes 312 are evenly distributed between adjacent baffle grooves 311; the even distribution of the filter holes 312 ensures the uniformity of the water flow when passing through the filter cover 31, thereby making the filtering effect more detailed and comprehensive. The filter holes 312 are designed with precise dimensions to intercept impurities of a specific size and prevent these impurities from entering the aquaculture water body, thereby protecting the cleanliness of the water environment and the health of the aquaculture organisms.

[0038] See also Figure 4 The bottom end of the filter cover 31 is fixedly connected with a plug-in tube 313, and the plug-in tube 313 is inserted into one end of the sewage pipe 32; this structural design makes the connection between the filter cover 31 and the sewage pipe 32 more stable, and facilitates the rapid discharge of filtered impurities through the sewage pipe 32, avoiding the accumulation of impurities in the filter cover 31 and affecting the filtration efficiency and water quality.

[0039] See also Figure 5, atomizing heads 71 ​​are evenly distributed on the top of the aeration plate 7, and an air inlet pipe 72 is fixedly connected to one side of the aeration plate 7; the evenly distributed design of the atomizing heads 71, combined with the high-pressure airflow delivered by the high-pressure air pump through the air inlet pipe 72, can effectively refine the gas into tiny bubbles, which have high solubility in water and greatly increase the dissolved oxygen content in the water. This oxygenation method is both efficient and can maintain the stability of the water environment, which is crucial to improving the dissolved oxygen level of the aquaculture water and promoting the healthy growth of aquatic organisms.

[0040] The working principle of the utility model is:

[0041] When in use, the water to be purified is transported to the interior of the coarse filter bin 1 through the main pipe 21. When the water flows out from the bottom of the main pipe 21, it falls on the diverter 22 located at the bottom of the main pipe 21. Then, under the action of the diverter 22, the water flows downward along the top inner wall of the filter cover 31. When the water flows inside the filter cover 31, impurities in the water will be filtered out by the filter cover 31, and the filtered water will fall onto the filter plate 5 through the filter hole 312.

[0042] At the same time, the impurities filtered by the filter cover 31 will fall into the bottom of the filter cover 31, and will be discharged to the outside of the coarse filter bin 1 through the sewage pipe 32 connected to the bottom of the filter cover 31; and the baffle groove 311 arranged in the filter cover 31 can slow down the speed of water flowing in the filter cover 31, thereby improving the filtering effect of the filter cover 31;

[0043] The coarse filter assembly 3 can initially filter the water and discharge the filtered residue in time, thereby extending the service life of the filter disc 5;

[0044] When the water filtered by the filter plate 5 falls onto the aeration plate 7, an air pump needs to be connected to the air inlet pipe 72 to deliver high-pressure airflow into the aeration plate 7. The atomizing head 71 arranged on the aeration plate 7 can divert the gas, thereby increasing the oxygen content of the filtered water. The oxygenated water will be discharged through the output pipe 41.

[0045] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
