Description

Technical Field

[0001] This utility model relates to the field of water recycling technology, specifically to a device for water recycling in aquaculture. Background Technology

[0002] At present, most aquaculture in my country adopts high-density pond farming. While this traditional farming method can ensure a significant increase in aquatic product output for a certain period of time, it also damages the farming environment. To solve this problem, wastewater recycling equipment is needed to recycle aquaculture wastewater and reduce the harm of aquaculture wastewater pollution.

[0003] A search revealed that Chinese patent application number CN202111220436.8 discloses an aquaculture water circulation treatment device, which includes a treatment box. A motor output end extends through the inner wall of the box and the outer wall of the treatment box to the interior and is fixedly sleeved with a rocker arm. The other end of the rocker arm is rotatably connected to a rack, and the other end of the rack is provided with a float collecting claw. Multiple wave-shaped rods are evenly arranged on the outer circumference of the stirring rod. The lower end of the stirring rod is provided with stirring blades. The lower end of the rotating shaft extends through the interior of the turntable A to the interior of the machine box and is fixedly sleeved with a helical gear A. The transmission relationship between helical gears A, B, and C causes the two layers of stirring blades to rotate in both directions, so that the medicine and water are fully mixed and reacted, improving the reaction efficiency.

[0004] In the process of implementing this invention, the inventors discovered the following problems with the prior art:

[0005] During use, when the water in the treatment tank is stirred by the stirring mechanism, impurities floating on the water surface will be stirred into the water. The float claw can only collect impurities floating on the water surface, but it is difficult to collect impurities that have been swept into the water or are floating on the bottom, thus reducing the impurity removal effect.

[0006] Therefore, the problem that this utility model urgently needs to solve is to provide a water circulation treatment device for aquaculture that can thoroughly filter impurities in water during use, improve the filtration effect, discharge the filtered impurities from the filter box, has a self-cleaning function, and does not require stopping the machine for cleaning during operation, thus improving the filtration efficiency. Utility Model Content

[0007] To address the aforementioned technical problems, the purpose of this utility model is to overcome the issue that in existing technologies, during the stirring process of water in the treatment tank using a stirring mechanism, impurities floating on the water surface are stirred into the water, and the float claws can only collect impurities floating on the surface, making it difficult to collect impurities that are swept into the water or floating at the bottom, thus reducing the impurity removal effect. Therefore, this invention provides a water circulation treatment device for aquaculture that can thoroughly filter impurities in the water during use, improving the filtration effect, and can discharge the filtered impurities from the filter tank.

[0011] The sedimentation tank, which is equipped with an internal stirring mechanism, has a vertically fixed dosing port at its upper end, which is connected to the interior of the tank, for stirring the drug.

[0012] Preferably, guide rollers for supporting the filter cloth are horizontally and rotatably provided on the filter box located below the two windows, and a pipe communicating with the interior of the filter box is vertically fixed at the bottom end of the filter box. The bottom end of the pipe is fixed to the top of the sedimentation box and communicates with the interior of the sedimentation box.

[0013] Preferably, a scraper that can abut against the filter cloth is fixedly provided at the upper end of each collection box opening near the filter cloth.

[0014] Preferably, the inner walls on both sides of the filter box located between the outlet end of the inlet pipe and the filter cloth are provided with a first buffer plate and a second buffer plate arranged in an alternating pattern.

[0015] Preferably, the device further includes a drive assembly for synchronously rotating the first and second rotating shafts, the drive assembly comprising: a power motor, a first chain, and a first sprocket; wherein,

[0016] The first rotating shaft and the second rotating shaft are respectively mounted horizontally and rotatably above the sedimentation tank via brackets, and a first chain is mounted on the same end of each shaft via a first sprocket. Either end of the second rotating shaft is coaxially connected to the power motor that is horizontally fixed on the bracket via a coupling.

[0017] Preferably, the device further includes a drainage mechanism, which comprises: a drain pipe, a float, and a drain pump; wherein,

[0018] The sedimentation tank is equipped with a float that can float on the water surface. A drain pipe is vertically fixed through the float. The outlet end of the drain pipe extends from the side wall at the top of the sedimentation tank and is fixedly connected to the input end of the drain pump fixed on the outer wall of the sedimentation tank.

[0019] Preferably, a drain pipe connected to the interior of the sedimentation tank is horizontally fixedly installed on the side wall at the bottom end of the sedimentation tank, and a switch valve is fixedly installed on the drain pipe.

[0020] Preferably, the stirring mechanism includes: a stirring shaft, stirring blades, and a power assembly; wherein,

[0021] The sedimentation tank is equipped with at least two vertically rotatable stirring shafts arranged at intervals inside. Each stirring shaft has several stirring blades fixed horizontally and evenly. The tops of the two stirring shafts extend from the top of the sedimentation tank and are connected together by a power assembly.

[0022] Preferably, the power assembly includes: a drive motor, a second chain, and a second sprocket; wherein,

[0025] According to the above technical solution, the beneficial effects of the aquaculture water circulation treatment device provided by this utility model in use are as follows:

[0026] (1) Water in the aquaculture pond enters the filter box from the top through the inlet pipe and is filtered through the filter cloth. Impurities floating in the aquaculture pond are filtered on the filter cloth. The filtered water enters the sedimentation tank from the bottom of the filter box. An appropriate amount of flocculant for purifying water is added to the sedimentation tank through the dosing port. The flocculant will gather the small particles of impurities in the water and coagulate them into flocs, which slowly settle at the bottom of the sedimentation tank, thereby further purifying and filtering the water so that the final water quality meets the standards.

[0027] (2) During filtration, the No. 1 rotating shaft and the No. 2 rotating shaft are rotated synchronously so that they rotate in the same direction, so that the No. 1 rotating shaft unwinds the filter cloth wound on it, and the No. 2 rotating shaft rewinds the unwound filter cloth. As the first and second rotating shafts rotate counterclockwise in sync, the first rotating shaft unwinds the filter cloth wound on it, while the second rotating shaft rewinds the unwound filter cloth. During this process, impurities trapped on the filter cloth inside the filter box move out through the window on the left side of the filter box and fall into the collection box directly below it. After the filter cloth on the first rotating shaft is unwound, the first and second rotating shafts rotate in opposite directions in sync. The second rotating shaft unwinds the filter cloth wound on it, while the first rotating shaft rewinds the unwound filter cloth, causing impurities trapped on the filter cloth inside the filter box to move out through the window on the right side of the filter box and fall into the collection box directly below it.

[0028] This invention can thoroughly filter impurities in water through a filtration mechanism, improving the filtration effect. It can also discharge the filtered impurities from the filter box and has a self-cleaning function, eliminating the need to stop the machine for cleaning during operation and thus improving filtration efficiency.

[0037] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0038] like Figure 1-4 As shown, the present invention provides an aquaculture water circulation treatment device, the device comprising: a sedimentation tank 1, a filter tank 2, a filter mechanism 3, and a stirring mechanism 11;

[0039] A filter box 2, connected to the interior of the sedimentation tank 1, is horizontally arranged above the sedimentation tank 1. A filtration mechanism 3 is installed inside the filter box 2. An inlet pipe 5 is fixedly installed at the top of the filter box 2. The filtration mechanism 3 includes: a first rotating shaft 301, a second rotating shaft 302, and a filter cloth 303.

[0040] A first rotating shaft 301 and a second rotating shaft 302 are horizontally rotatable and spaced apart at the upper end of the sedimentation tank 1 located below the filter tank 2. Window openings communicating with the interior of the filter tank 2 are symmetrically opened on both sides of the filter tank 2. The two ends of the filter cloth 303, which passes horizontally inside the filter tank 2, exit through the two windows of the filter tank 2 and are respectively wound around the first rotating shaft 301 and the second rotating shaft 302. Collection boxes 9 are horizontally fixedly installed on the sedimentation tank 1 directly below the two discharge ends of the filter cloth 303.

[0041] The sedimentation tank 1, which is equipped with a stirring mechanism 11, has a vertically fixed dosing port 17 at its upper end, which is connected to the interior of the tank, for stirring the drug.

[0042] In the above scheme, the water inlet pipe 5 on the filter box 2 is connected to the aquaculture pond. A water inlet pump is fixedly installed on the water inlet pipe 5. The water inlet pump is started to input the water in the aquaculture pond into the filter box 2 for subsequent treatment.

[0043] In use, water from the aquaculture pond enters the filter box 2 from the top through the inlet pipe 5 and is filtered through the filter cloth 303. Impurities floating in the aquaculture pond are filtered onto the filter cloth 303. The filtered water then enters the sedimentation tank 1 from the bottom of the filter box 2. An appropriate amount of flocculant for purifying water is added to the sedimentation tank 1 through the dosing port 17. The flocculant gathers small particles of impurities in the water, coagulates them into flocs, and slowly settles at the bottom of the sedimentation tank 1, thereby further purifying and filtering the water so that the final water quality meets the standards.

[0044] Flocculants are classified into inorganic flocculants and organic flocculants. Inorganic flocculants include aluminum sulfate or ferric chloride, while organic flocculants include polyacrylamide.

[0045] In addition, the filter mechanism 3 is used in the following way: during filtration, the first rotating shaft 301 and the second rotating shaft 302 are rotated synchronously so that they rotate in the same direction, so that the first rotating shaft 301 unwinds the filter cloth 303 wound on it, while the second rotating shaft 302 winds up the unwound filter cloth 303.

[0046] like Figure 2 As shown, when the first rotating shaft 301 and the second rotating shaft 302 rotate counterclockwise synchronously, the first rotating shaft 301 unwinds the filter cloth 303 wound on it, while the second rotating shaft 302 rewinds the unwound filter cloth 303. During this process, impurities blocked on the filter cloth 303 located in the filter box 2 move out from the window on the left side of the filter box 2 and fall into the collection box 9 located directly below it. After the filter cloth 303 on the first rotating shaft 301 is unwound, the first rotating shaft 301 and the second rotating shaft 302 are rotated in opposite directions and synchronously so that the second rotating shaft 302 unwound the filter cloth 303 wound on it, while the first rotating shaft 301 rewound the unwound filter cloth 303, so that the impurities blocked on the filter cloth 303 located in the filter box 2 are moved out from the window on the right side of the filter box 2 and fall into the collection box 9 located directly below it.

[0047] In a preferred embodiment of this utility model, guide rollers 8 for supporting the filter cloth 303 are horizontally and rotatably arranged on the filter box 2 located below the two windows. A pipe 4 communicating with the interior of the filter box 2 is vertically fixed at the bottom end of the filter box 2. The bottom end of the pipe 4 is fixed to the top of the sedimentation tank 1 and communicates with the interior of the sedimentation tank 1.

[0048] In the above scheme, the two ends of the filter cloth 303 passing through the inside of the filter box 2 pass through the upper ends of the two guide rollers 8 respectively and are wound around the first rotating shaft 301 and the second rotating shaft 302 respectively. Under the action of the two guide rollers 8, the filter cloth 303 passing through the inside of the filter box 2 is kept in a horizontal state to block and accept impurities in the water.

[0049] In a preferred embodiment of the present invention, a scraper 10 that can abut against the filter cloth 303 is fixedly provided at the upper end of the opening of each collection box 9 near the filter cloth 303.

[0050] In the above scheme, the scraper 10 scrapes off the impurities adhering to the filter cloth that is moving and being rolled up on the adjacent first rotating shaft 301 or second rotating shaft 302, so as to improve the cleanliness of the filter cloth 303.

[0051] In a preferred embodiment of this utility model, the inner walls on both sides of the filter box 2 located between the outlet end of the water inlet pipe 5 and the filter cloth 303 are provided with a first buffer plate 6 and a second buffer plate 7 arranged in an alternating pattern.

[0052] In the above scheme, the water entering the filter box 2 from the water inlet pipe 7 passes through the second buffer plate 7 and then the first buffer plate 6 before falling onto the filter cloth 303 for filtration. The first buffer plate 6 and the second buffer plate 7 play a role in buffering and decelerating, thereby reducing the impact force of the water on the filter cloth 303, thus protecting the filter cloth 303 and extending its service life.

[0053] In a preferred embodiment of this utility model, the device further includes a drive assembly for driving the first rotating shaft 301 and the second rotating shaft 302 to rotate synchronously. The drive assembly includes: a power motor, a first chain, and a first sprocket; wherein,

[0054] The first rotating shaft 301 and the second rotating shaft 302 are respectively mounted horizontally and rotatably above the sedimentation tank 1 via brackets, and a first chain is mounted on the same end of each shaft via a first sprocket. Any end of the second rotating shaft 302 is coaxially connected to the power motor that is horizontally fixed on the bracket via a coupling.

[0055] In the above scheme, when in use, with the cooperation of the two sprockets on the first chain and the first shaft 301 and the second shaft 302, the first shaft 301 and the second shaft 302 can be synchronously driven to rotate in the same direction by starting the power motor.

[0056] In a preferred embodiment of this utility model, the device further includes a drainage mechanism, which comprises: a drain pipe 12, a float 13, and a drain pump 14; wherein,

[0057] The sedimentation tank 1 is equipped with a float 13 that can float on the water surface. A drain pipe 12 is vertically fixed through the float 13. The water outlet of the drain pipe 12 extends out from the side wall at the top of the sedimentation tank 1 and is fixedly connected to the input end of the drain pump 14 fixed on the outer wall of the sedimentation tank 1.

[0058] In the above scheme, the density of the float 13 is less than that of water, so that the float 13 can float on the water surface, and the drain pipe 12 is made of flexible material.

[0059] In use, after adding an appropriate amount of flocculant to the sedimentation tank 1, the water in the sedimentation tank 1 separates into layers, causing impurities in the water to form flocculent matter and settle at the bottom of the sedimentation tank 1, while clear water remains above the flocculent matter, forming a separate layer. After settling and separating, the float 13 floats on the water surface, and the inlet end of the drain pipe 12 is fixed to the float 13 and located below the liquid surface. At this time, the drain pump 14 is started to discharge the filtered clear water through the drain pipe 12 into a designated container. During the pumping process, because the inlet end of the drain pipe 12 is always in contact with the liquid surface through the float 13, it prevents the flocculent impurities settled at the bottom of the sedimentation tank 1 from being pumped out along with the water.

[0060] When the float 13 descends with the liquid level to a position 4-5 cm above or close to the top of the flocculent material, the operation of the drainage pump 14 can be stopped.

[0061] In a preferred embodiment of this utility model, a drain pipe 16 connected to the interior of the sedimentation tank 1 is horizontally fixedly provided on the side wall at the bottom end of the sedimentation tank 1, and a switch valve is fixedly provided on the drain pipe 16.

[0062] In the above scheme, the flocculent impurities deposited on the bottom of the sedimentation tank 1 can be discharged through the drain pipe 16.

[0063] In a preferred embodiment of this utility model, the stirring mechanism 11 includes: a stirring shaft 1101, stirring blades 1102, and a power assembly 1103; wherein,

[0064] The sedimentation tank 1 is provided with at least two stirring shafts 1101 arranged vertically and rotatably at intervals inside. Each stirring shaft 1101 is provided with several stirring blades 1102 fixed horizontally and evenly. The tops of the two stirring shafts 1101 extend from the top of the sedimentation tank 1 and are connected together by a power assembly 1103.

[0065] In the above scheme, when flocculant is added into the sedimentation tank 1, the two stirring shafts 1102 are rotated to drive the stirring blades 1102 on each shaft to rotate, so that the flocculant added into the sedimentation tank 1 can be stirred to make the flocculant fully mixed with water.

[0066] In a preferred embodiment of this utility model, the power assembly 1103 includes: a drive motor, a second chain, and a second sprocket; wherein,

[0067] The top of each of the two stirring shafts 1101 is equipped with a chain number 2 via a sprocket number 2, and the top of any one of the stirring shafts 1101 is coaxially connected to the drive motor that is vertically fixed above the sedimentation tank 1 via a coupling.

[0068] In the above scheme, during use, the two second sprockets and the second chain on the two stirring shafts 1101 work together to drive the two stirring shafts 1101 to rotate synchronously by starting the drive motor, thereby realizing the stirring function.

[0069] In a preferred embodiment of the present invention, a guide rod 15 is vertically fixed inside the sedimentation tank 1, and a guide hole is vertically opened on the float 13 for the guide rod 15 to pass through, and the guide rod 15 is mounted on the guide rod 15 in a way that allows it to be raised and lowered through the guide hole.

[0070] In the above scheme, the guide rod 15 plays a guiding role. Under the action of the guide rod 15, the float 13 can only descend along the direction of the liquid surface, preventing it from deviating and causing the float 13 to collide with the stirring mechanism 12.

[0071] In summary, the aquaculture water circulation treatment device provided by this utility model overcomes the problem in the prior art where, during the stirring process of the water in the treatment tank by the stirring mechanism, impurities floating on the water surface are stirred into the water, and the collecting claw can only collect impurities floating on the water surface, but it is difficult to collect impurities that are swept into the water or floating on the bottom, thus reducing the impurity removal effect.

[0072] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0073] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0074] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
