DETAILED DESCRIPTION

[0057] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] Please refer to Figure 1-Figure 9 The present invention discloses a plankton aquaculture tailwater treatment and purification system, which is mainly used in water pollution treatment. The main structure includes a steel frame 1, a closed frame 2, a microfilter 3, a power device 4 and a circulation pump 5, wherein a screw 6 is installed in the circulation pump 5, and the screw 6 is transmission-connected to the microfilter 3 through a cross shaft 9. It should be noted that the screw 6 is vertically arranged in the circulation pump 5, and a spiral sheet is arranged outside the screw 6. The water body is drawn up during the rotation process, so as to facilitate the water body in the water storage container 7 to be drawn into the microfilter 3.

[0059] In this embodiment, Figure 1 As shown, the microfilters 3 are arranged in pairs in the closed frame 2, which can significantly improve the efficiency of water treatment. Of course, in order to further improve the filtering effect, more than two microfilters 3 and circulating pumps 5 can be arranged. In addition, a rotating cage 10 is also movably arranged inside the closed frame 2. In addition, a power device 4 is also installed outside the closed frame 2. The power device 4 can synchronously drive the two microfilters 3 to rotate, and then the microfilters 3 drive the two screws 6 to rotate, so as to achieve the purpose of introducing water into the microfilter 3. In addition, since the microfilter 3 rotates itself, the filtering efficiency can be further improved by centrifugal force.

[0060] In this embodiment, the microfilter 3 is disposed in the rotating cage 10 and at the axis, and can drive the rotating cage 10 to rotate. Figure 2As shown, the microfilter 3 includes a drum 31, a centrifugal cover 32 and a liquid inlet 35, wherein the liquid inlet 35 is arranged at the rear end of the drum 31, and the drum 31 is connected to the transmission member 33 through the liquid inlet 35, so that the water body can be introduced into the drum 31 through the circulation pump 5. In this embodiment, the size and number of the liquid inlet 35 can be pre-set according to the size of the water flow rate, a hollow shaft 34 is arranged at the center of the front end of the drum 31, a transmission member 33 is arranged at the rear end, and a plurality of through grooves 36 are evenly arranged on the side, and the hollow shaft 34 is connected to the drum 31. The through groove 36 is hingedly provided with a centrifugal cover 32, and an elastic component is arranged at the hinge. When the drum 31 rotates, the centrifugal cover 32 is expanded outward under the action of centrifugal force, suitable for being close to the rotating cage 10, and driving the rotating cage 10 to rotate, and at the same time, the centrifugal cover 32 can block the outer wall of the rotating cage 10, so that the centrifugal cover 32 can achieve the effect of water purification and filtration.

[0061] In this embodiment, if Figure 6 The rotating cage 10 includes a cage frame 101, an annular guide rail 102 and a limiting bar 103, wherein the cage frame 101 is a cylindrical body, and a plurality of limiting bars 103 are arranged on the inner wall of the drum 31, and a plurality of limiting grooves 104 are arranged between two adjacent limiting bars 103. When the micro-filter plate 321 is unfolded, the micro-filter plate 321 can abut against the limiting bars 103 to drive the cage frame 101 to rotate, and the micro-filter plate 321 covers the limiting groove 104, so that when the water flows out of the limiting groove 104, the impurities can be retained on the micro-filter plate 321. In addition, an annular guide rail 102 is arranged at the end of the cage frame 101, and the drum 31 is slidably arranged inside the annular guide rail 102, thereby reducing wear and preventing water from overflowing.

[0062] In some embodiments, Figure 3 and Figure 4 The centrifugal cover 32 includes a microfilter plate 321 and a support plate 322. The support plate 322 is hingedly arranged in the through slot 36, and a torsion spring is arranged at the hinge. The middle part of the microfilter plate 321 is hingedly connected to the end of the support plate 322, so that the microfilter plate 321 can be easily unfolded under the action of centrifugal force. In this embodiment, the microfilter plate 321 and the support plate 322 are both frame structures, and filter screens are arranged in the microfilter plate 321 and the support plate 322 to improve the filtering effect.

[0063] Based on the above structure, this embodiment achieves the filtering effect of the aquaculture water body and also has the function of self-cleaning the microfilter 3. The above effect is mainly achieved by adjusting the operating state, which is described in detail as follows:

[0064] When not started or in the initial start-up state, the drum 31 is in a low speed state, the centrifugal cover 32 maintains its original state due to the elastic force, and the water is gradually introduced into the microfilter 3;

[0065] The high-speed mode is started, so that the drum 31 rotates at a high speed. The micro-filter plate 321 is acted upon by centrifugal force, overcoming the elastic force between the support plate 322 and the through groove 36, so that the micro-filter plate 321 covers the limiting groove 104. A large amount of water quickly enters the drum 31 and flows out from the through groove 36 into the rotating cage 10, so that the water is filtered by the micro-filter plate 321 and the support plate 322. The filtered water flows out from the cage frame 101, and impurities are retained and filtered on the micro-filter plate 321 and the support plate 322.

[0066] After a period of filtration, the low-speed mode is started, the water storage container 7 stores clean water that has been filtered through multiple cycles, and the drum 31 rotates at a low speed. Under the action of elastic force, the support plate 322 retracts to the through groove 36, and the micro-filter plate 321 covers the drum 31, and the drum 31 is surrounded by a closed structure. At this time, the water entering the microfilter 3 from the liquid inlet hole 35 washes the impurities attached to the micro-filter plate 321 and the support plate 322 with clean water, and flows out from the hollow shaft 34, thereby achieving self-cleaning of the microfilter 3.

[0067] In some embodiments, Figure 3 The transmission member 33 includes a gear plate 331 and a transmission shaft 333, wherein a rotary joint 332 is provided at the front center of the gear plate 331. It should be noted that a liquid inlet hole 35 is provided in the rotary joint 332 so that the water introduced by the circulation pump can enter the drum 31. In this embodiment, the rear end of the transmission shaft 333 is arranged at the center of the gear plate 331, and the head end is connected to the cross shaft 9 through a universal joint. In other words, the transmission shaft 333 directly drives the screw 6 to rotate through the cross shaft 9, and the water introduced by the circulation pump 5 enters the drum 31 along the cross shaft 9 through the liquid inlet hole 35 to achieve water diversion and filtration.

[0068] In this embodiment, optionally, Figure 5 The power device 4 includes a motor 41 and a transmission gear 42. The motor 41 is coaxially connected to the transmission gear 42. The transmission gear 42 is meshingly connected to the gear plate 331. Of course, based on the technology adopted in this embodiment, the use of other transmission methods is also within the protection scope of the present invention.

[0069] In some embodiments, Figure 8 The water storage container 7 includes a sedimentation tank 71 and a filter grate 72. A water inlet 73 is provided at the front end of the sedimentation tank 71 for introducing water from the pond into the sedimentation tank 71. The filter grate 72 is obliquely inserted into the top of the sedimentation tank 71, which can effectively block floating objects from entering the microfilter 3.

[0070] In some embodiments, the sedimentation tank 71 is made of plastic material, which can effectively reduce costs, and a steel frame 1 is wrapped around the sedimentation tank 71 to prevent the sedimentation tank 71 from being deformed by force. Figure 7As shown, a movable part (not shown in the figure) may be provided at the bottom of the steel frame 1 to facilitate the movement of the entire filtering device. In addition, an aeration sheet 8 is provided on the top of the steel frame 1, and a plurality of aeration pipes (not shown in the figure) are provided in the aeration sheet 8. An air inlet is provided on the side of the aeration sheet 8 to connect the aeration pipe, and aeration gas is introduced through the connecting air inlet pipe (not shown in the figure). The water filtered by the microfilter 3 flows downward into the aeration sheet 8, and returns to the sedimentation tank 71 through the aeration sheet 8. The aeration sheet 8 can increase the amount of oxygen dissolved in the water by increasing the contact area with oxygen, thereby increasing the dissolved oxygen in the aquaculture water.

[0071] In some embodiments, Fig. 9 As shown, the closed frame 2 includes a frame 21, a front support bearing 22 and a rear support frame 23, wherein the outer side of the frame 21 is inlaid with transparent glass to facilitate observation of the operation of the microfilter 3. The front support bearing 22 is internally provided with a rotating cage 10 and is arranged at the front end of the frame 21, and the rear support frame 23 is internally provided with a transmission member 33 and is arranged at the rear end of the frame 21, thereby ensuring the normal operation of the microfilter 3.

[0072] Based on the same inventive concept, the present invention also discloses a method for treating and purifying tail water of plankton aquaculture, comprising the above-mentioned system for treating and purifying tail water of plankton aquaculture, and comprising the following steps:

[0073] S1. Start the power device 4, drive the drum 31 to rotate through the transmission member 33, and at the same time, the drum 31 drives the screw 6 to rotate through the cross shaft 9, so that the water in the water storage container 7 is injected into the drum 31;

[0074] S2. Start the high-speed mode, so that the drum 31 rotates at a high speed, and the microfilter plate 321 is subjected to the centrifugal force, overcoming the elastic force between the support plate 322 and the through groove 36, so that the microfilter plate 321 covers the limit groove 104, thereby using the microfilter plate 321 and the support plate 322 to filter the water;

[0075] S3. Start the low speed mode, the water storage container 7 contains clean water, and the drum 31 rotates at a low speed. Under the action of elastic force, the support plate 322 retracts to the through groove 36, and the microfilter plate 321 covers the drum 31. At this time, the impurities attached to the microfilter plate 321 and the support plate 322 are washed by clean water and flow out from the hollow shaft 34.

[0076] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
