Description

Technical Field

[0001] The present application relates to the field of aquaculture technology, and in particular to an aquaculture tail water purification device. Background Art

[0002] At present, with the rapid development of my country's economy and the improvement of social living standards, the demand for aquatic products has increased year by year, and the aquaculture industry has developed rapidly; however, the discharge of bait, the decomposition of leftover bait, the production of excrement, and the use of chemicals and antibiotics in the breeding process have caused the nutrients and organic debris in the water to seriously exceed the standard, resulting in an imbalance in the ecosystem of the aquaculture waters, thereby restricting the sustainable development of the aquaculture industry. Therefore, it is necessary to use purification treatment equipment to purify the aquaculture effluent and carry out corresponding treatment.

[0003] Traditional tailwater treatment technology, especially in the filtration device, is easily blocked by aquatic plants, plastic bags, etc., which requires constant manual cleaning, increasing labor costs and reducing water treatment efficiency. Summary of the Invention

[0004] In order to reduce labor costs and improve water treatment efficiency, the present application provides an aquaculture tail water purification device.

[0005] The aquaculture tail water purification device provided in this application adopts the following technical solutions:

[0006] The aquaculture tailwater purification device includes a box body, which is divided into a filter chamber and a collection chamber. A water inlet and a water outlet are provided on the box body, and the water inlet and the water outlet are both connected to the filter chamber. A filter mechanism is installed in the filter chamber; a rotating rod is rotatably provided in the box body, and two groups of cleaning components for cleaning aquatic plants, plastic bags, etc. are provided on the rotating rod. The two groups of cleaning components are symmetrically arranged about the rotating rod, and a first motor for driving the rotating rod to rotate is provided on the box body.

[0007] By adopting the above technical solution, the tail water to be cleaned enters the filter chamber from the water inlet, the first motor drives the rotating rod to rotate, and the rotating rod drives the cleaning component to start. After the tail water enters the filter chamber, it passes through the cleaning component and the filtering mechanism respectively, and then is discharged from the water outlet. Large-volume garbage such as aquatic plants and plastic bags in the tail water is cleaned by the cleaning component, and then the filtering mechanism continues to further clean the tail water, and the cleaned impurities, aquatic plants and other objects are accumulated in the collection chamber, which is convenient for the staff to handle them in a unified manner, thereby reducing labor costs and improving water treatment efficiency.

[0008] Preferably, a sleeve is fixedly connected to the rotating rod, and the cleaning assembly includes a connecting block and a plurality of blocking rods. The connecting block is fixedly connected to the sleeve, and the plurality of blocking rods are hinged to the connecting block.

[0009] By adopting the above technical solution, when the tail water enters the filter chamber from the water inlet, it first passes through multiple blocking bars, which can effectively hook large garbage such as water plants and plastic bags in the tail water, thereby reducing the chance of water plants and other garbage clogging the filter device and thus improving the filtration efficiency.

[0010] Preferably, a through opening is opened on the inner wall of the filter chamber, a hinged rod is rotatably provided on the inner wall of the through opening, a sealing door is sleeved on the hinged rod, a first torsion spring is sleeved on the hinged rod, and both ends of the first torsion spring are respectively fixedly connected to the sealing door and the hinged rod.

[0011] By adopting the above technical solution, when the barrier rod is full of impurities such as water plants, the first motor starts to drive the rotating rod to rotate, and the rotation of the rotating rod drives the barrier rod to rotate. The rotation of the barrier rod will push the sealing door to overcome the first torsion spring to open, and pass through the sealing door into the collection chamber, and place the water plants and other impurities on it in the collection chamber for storage.

[0012] Preferably, an arc-shaped rod is rotatably provided on the connecting block, the arc-shaped rod abuts against the blocking rod, a dual-axis motor is fixedly installed in the connecting block, and the two rotating shafts of the dual-axis motor are respectively fixedly connected to the two ends of the arc-shaped rod.

[0013] By adopting the above technical solution, when the blocking rod is rotated into the collecting chamber, the dual-axis motor starts to drive the arc rod to rotate until it abuts against the blocking rod and pushes the blocking rod to rotate downward. When the blocking rod is rotated vertically downward, impurities such as water plants on it slide downward into the collecting chamber due to their own gravity. Subsequently, when the arc rod rotates upward under the drive of the dual-axis motor, the blocking rod follows and rotates upward to a horizontal state.

[0014] Preferably, a push block is slidably provided on the blocking rod, a sliding groove is provided on the side wall of the blocking rod, a slider is fixedly connected to the push block, the slider slides in the sliding groove, the push block is magnetic, and the arc rod is an electromagnet.

[0015] By adopting the above technical solution, when the barrier rod is in a horizontal state, the arc rod and the push block attract each other, and the push block is close to the arc rod. When the barrier rod rotates toward the vertical direction, the arc rod and the push block repel each other, and the push block moves away from the arc rod under the magnetic force and its own gravity, and pushes the water plants on the barrier rod downward to detach, thereby accelerating the detachment of water plants and other impurities on the barrier rod.

[0016] Preferably, the filtering mechanism comprises a primary filter plate and a secondary filter plate, the primary filter plate is a physical filter with a plurality of filter holes formed thereon, and the secondary filter plate is a biomembrane filter.

[0017] By adopting the above technical solution, after the barrier bar removes larger impurities such as aquatic plants, the tail water passes through the first filter plate to remove smaller solid impurities therein, and then passes through the biofilm of the second filter plate to reduce the content of organic matter in the tail water, thereby achieving the effect of purifying the tail water.

[0018] Preferably, a push plate is slidingly provided on the first-level filter plate, a screw is rotatably provided in the filter chamber, the push plate is threadedly connected to the screw, a second motor is installed on the outer wall of the box body, the rotating shaft of the second motor is fixedly connected to the screw, a hinged door is opened on the inner wall of the filter chamber, the hinged door is connected to the collecting chamber, and a control block for controlling the hinged door switch is installed on the inner wall of the filter chamber.

[0019] By adopting the above technical solution, after a period of tail water filtration, a large amount of solid impurities accumulate on the first-level filter plate. The staff starts the second motor, and the second motor rotates through the screw to drive the push plate on the first-level filter plate to push the solid impurities on it to slide toward the hinged door. When the push plate is less than the set distance from the control block, the control block controls the hinged door to open, thereby facilitating the push plate to push the impurities into the collection chamber. When the push plate is away from the hinged door, the control block controls the hinged door to close.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The tail water to be cleaned enters the filter chamber from the water inlet, and the first motor drives the rotating rod to rotate, which drives the cleaning component to start. After the tail water enters the filter chamber, it passes through the cleaning component and the filtering mechanism respectively, and then is discharged from the water outlet. Large-volume garbage such as aquatic plants and plastic bags in the tail water is cleaned by the cleaning component, and then the filtering mechanism continues to further clean the tail water. The cleaned impurities, aquatic plants and other objects are accumulated in the collection chamber, which is convenient for the staff to handle them in a unified manner, thereby reducing labor costs and improving water treatment efficiency.

[0022] 2. When the tailwater enters the filter chamber from the water inlet, it first passes through multiple barrier bars. The barrier bars can effectively hook large garbage such as water plants and plastic bags in the tailwater, thereby reducing the chance of water plants and other garbage clogging the filter device and thus improving the filtration efficiency;

[0023] 3. When the barrier bar is in a horizontal state, the arc rod and the push block attract each other, and the push block is close to the arc rod. When the barrier bar rotates toward the vertical direction, the arc rod and the push block repel each other. The push block moves away from the arc rod under the magnetic force and its own gravity, and pushes the water plants on the barrier bar downward to detach, thereby accelerating the detachment of water plants and other impurities on the barrier bar.

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] The present application embodiment discloses an aquaculture tail water purification device, such as Figure 1 and Figure 2 As shown, the aquaculture tailwater purification device includes a rectangular parallelepiped housing 1 with a partition plate 28 fixedly mounted therein. The partition plate 28 divides the cavity within the housing 1 into a filter chamber 2 and a collection chamber 3. A door 33 is mounted on the sidewall of the collection chamber 3. A water inlet 4 and a water outlet 5 are fixedly mounted on the housing 1, both of which are connected to the filter chamber 2. The water inlet 4 is mounted at the top of the filter chamber 2, and the water outlet 5 is mounted at the bottom of the filter chamber 2. A diverter plate 29 is fixedly welded to the lower end of the water inlet 4 within the filter chamber 2. The diverter plate 29 is arranged at an angle. A filter mechanism 6 for purifying tailwater is mounted within the filter chamber 2. A rotating rod 7 is rotatably mounted within the housing 1. Two cleaning assemblies 8 for cleaning aquatic plants, plastic bags, etc. are mounted on the rotating rod 7. The two cleaning assemblies 8 are symmetrically arranged about the rotating rod 7. A first motor 9 is mounted on the housing 1 to drive the rotating rod 7.

[0033] like Figure 2 and Figure 3As shown, the rotating rod 7 passes through and rotates within the partition plate 28. The partition plate 28 has a through-hole 13 formed therein. A sleeve 10 is fixedly welded to the rotating rod 7. The sleeve 10 rotates within the through-hole 13. Two sealing doors 15 are located on the inner wall of the through-hole 13, one at each end of the sleeve 10. The cleaning assembly 8 includes a connecting block 11 and multiple blocking rods 12. The connecting block 11 is spherical and fixedly welded to the side wall of the sleeve 10. Multiple sets of connecting assemblies 30 are provided on the connecting block 11, and the multiple blocking rods 12 are arranged in a one-to-one correspondence with the multiple connecting assemblies 30. The connecting assembly 30 includes two connecting plates, between which a fixed rod is fixedly welded. The blocking rods 12 are rotatably sleeved on the fixed rods.

[0034] like Figure 3 and Figure 4 As shown, combined with Figure 5 As shown, hinged rods 16 are rotatably provided on the inner walls of the opening 13 on both sides of the sleeve 10, and a sealing door 15 is sleeved on the hinged rod 16. A first torsion spring 14 is sleeved on the hinged rod 16, and the two ends of the first torsion spring 14 are fixedly welded to the sealing door 15 and the side wall of the opening 13. The blocking rod 12 can abut and push the sealing door 15 to rotate and open the opening 13. An arc rod 17 is rotatably provided on the connecting block 11, and a dual-axis motor 18 is fixedly installed on the inner wall of the connecting block 11. The arc rod 17 includes an arc rod and two straight rods. The two straight rods are fixedly welded to the two ends of the arc rod and arranged along the diameter direction of the arc rod. The two straight rods are fixedly welded to the two rotating shafts of the dual-axis motor 18, and the arc rod abuts the blocking rod 12. The arc rod is an electromagnet, which has different magnetic properties depending on the direction of current flow. The blocking rod 12 is passed through the arc rod, and a push block 19 slides on the blocking rod 12. The push block 19 is cylindrical, and a slide groove 20 is opened on the side wall of the blocking rod 12. A slider 34 is fixedly welded to the inner wall of the push block 19. The slider 34 slides in the slide groove 20, and the push block 19 is magnetic.

[0035] like Figure 2 and Figure 3 As shown, when the tail water enters the filter chamber 2 from the water inlet 4, it first passes through the diverter plate 29 to relieve the impact force of the water. The diverter plate 29 is inclined toward the blocking rod 12, so that the water flows toward the blocking rod 12 and flows into the filter mechanism 6 after passing through multiple blocking rods 12. When the tail water passes through the blocking rod 12, the multiple blocking rods 12 can effectively hook larger garbage such as aquatic plants and plastic bags in the tail water, thereby reducing the clogging of the filter device by garbage such as aquatic plants, thereby improving the filtration efficiency.

[0036] like Figure 2 and Figure 3 As shown, combined with Figure 4 and Figure 5As shown, after a period of time, the first motor 9 is started, and the first motor 9 drives the rotating rod 7 to rotate. The rotating rod 7 rotates to drive the sleeve 10 and the connecting block 11 to rotate, thereby driving the blocking rod 12 to rotate until it abuts against the sealing door 15 and pushes the sealing door 15 open, so that the cleaning component in the original filter chamber 2 is rotated into the collecting chamber 3, and the cleaning component in the original collecting chamber 3 is rotated into the filter chamber 2. After the blocking rod 12 with impurities such as water plants rotates into the collecting chamber 3, the dual-axis motor 18 in the connecting block 11 is started, driving the arc rod 17 to rotate and pushing the blocking rod 12 to rotate vertically downward. At this time, impurities such as water plants on the blocking rod 12 fall off into the collecting chamber 3 under the action of gravity. When the arc rod 17 is in a horizontal state before rotating, the arc rod 17 and the push block 19 attract each other. When the arc rod 17 is in a vertical state after rotating, the arc rod 17 and the push block 19 repel each other. Therefore, when the blocking rod 12 rotates to a vertical state, the push block 19 slides on the blocking rod 12 away from the arc rod 17 under the push of the magnetic force, thereby accelerating the shedding of impurities such as water plants on the blocking rod 12; after the impurities such as water plants fall off, the dual-axis motor 18 controls the arc rod 17 to rotate with the blocking rod 12 to a horizontal state. At this time, the electrode on the arc rod 17 is converted and attracts the push block 19 to approach the arc rod 17.

[0037] like Figure 2 As shown, the filtration mechanism 6 includes a primary filter plate 21 and a secondary filter plate 22. Both the primary filter plate 21 and the secondary filter plate 22 are fixedly welded to the inner wall of the filter chamber 2, with the primary filter plate 21 located above the secondary filter plate 22. The primary filter plate 21 is a physical filter having multiple filter holes, while the secondary filter plate 22 is a biofilm filter. A push plate 23 is slidably provided on the upper surface of the primary filter plate 21. A screw 24 is rotatably provided within the filter chamber 2. The push plate 23 is threadedly connected to the screw 24. A second motor 26 is fixedly mounted on the outer wall of the housing 1. The shaft of the second motor 26 is fixedly welded to one end of the screw 24. A hinged door 25 is provided on the inner wall of the filter chamber 2 away from the second motor 26. The hinged door 25 is connected to the collection chamber 3. A control block 27 for controlling the opening and closing of the hinged door 25 is mounted on the inner wall of the filter chamber 2. The control block 27 can detect the distance between the hinged door 25 and the push plate 23.

[0038] like Figure 2As shown, after the blocking rod 12 removes larger impurities such as water plants, the tail water passes through the primary filter plate 21 to remove smaller solid impurities therein, and then passes through the biofilm of the secondary filter plate 22 to reduce the content of organic matter in the tail water, thereby achieving the effect of strengthening the purification of the tail water. After the tail water has been filtered for a period of time, a large amount of solid impurities have accumulated on the primary filter plate 21. The staff starts the second motor 26, and the second motor 26 rotates through the screw 24 to drive the push plate 23 on the primary filter plate 21 to push the solid impurities thereon to slide toward the hinged door 25. When the distance between the push plate 23 and the control block 27 is less than the set distance, the control block 27 controls the hinged door 25 to open, thereby facilitating the push plate 23 to push the impurities into the collection chamber 3. When the push plate 23 is away from the hinged door 25, the control block 27 controls the hinged door 25 to close.

[0039] The implementation principle of the embodiment of the present application is: the tail water to be cleaned enters the filter chamber 2 from the water inlet 4, passes through the diverter plate 29 to reduce the impact force, and then passes through multiple blocking rods 12. The blocking rods 12 can effectively intercept impurities such as aquatic plants and plastics. Subsequently, the tail water intercepted by the blocking rods 12 is further filtered through the filter mechanism 6, and the filtered impurities are transported to the collection chamber 3, thereby reducing the possibility of blockage caused by impurities such as aquatic plants and plastic bags, thereby reducing labor costs and improving water treatment efficiency.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
