Description

Technical Field

[0001] The present invention relates to the technical field of sewage filtration equipment, and specifically to a water quality purification equipment for Macrobrachium rosenbergii breeding ponds. Background Technique

[0002] During the breeding process of Macrobrachium rosenbergii, water quality purification is the core technology to maintain a good water environment, which directly affects the survival rate and growth rate of shrimp larvae;

[0003] During the long-term use of Macrobrachium rosenbergii breeding ponds, pollutants such as residual bait and feces will accumulate at the bottom of the shrimp breeding ponds. The long-term accumulation of these pollutants will affect the breeding and survival of Macrobrachium rosenbergii. Therefore, generally, breeders will use a filtering device with a straw at one end and a filter plate at the other end of the straw to filter the pollutants at the bottom of the breeding pond. Since sludge and shrimp shells will also accumulate at the bottom of the shrimp breeding pond after long-term use, when the sludge and shrimp shells pass through the filtering component, the filtering component will be blocked by the sludge and shrimp shells. The blockage will cause the purification efficiency of the filtering component for residual bait and feces to decrease, resulting in ineffective filtering and purification of the shrimp breeding pond, thus affecting the survival conditions of Macrobrachium rosenbergii.

[0019] The present invention has the following beneficial effects:

[0020] (1) A drum is provided inside the present invention, and several filter belts are arranged around the inner wall of the drum. The drum rotates on the inner wall of the outer shell. When the pool water flows into the inner wall of the drum through the water inlet pipe, the rotating drum will use centrifugal force to swing the pool water to form a vortex. The vortex pool water will continuously impact the filter belt and the filter baffle. The filter baffle will filter out sludge, residual bait, and feces in the pool water by using its transmission. Under the continuous centrifugal swinging of the drum, the sludge, residual bait, and feces in the pool water can be effectively filtered. At the same time, when the subsequent pool water fills the drum, the filtered water will be discharged through the water outlet pipe.

[0021] (2) A scraping plate is provided in the present invention. After the filter belt and the filter baffle filter the pollutants in the pool water, the filter belt and the drum will continuously perform circular motion in the opposite direction at a constant speed on the inner wall of the outer shell. At the same time, when the filter belt and the drum perform circular motion, the filter belt will contact and scrape with the scraping plate. The pollutants filtered by the filter belt and the filter baffle will be peeled off into the space between the drum and the outer shell. At this time, after scraping and cleaning, the filter baffle will then return to the inner wall of the drum for filtering work. Through this design, the cyclic cleaning of the filter baffle can be realized, and the problem of filter blockage can be prevented.

[0022] (3) A pressure filter plate is provided inside the present invention. When the drum rotates, the drum will drive the screw rod to rotate through linkage. When the screw rod rotates, it will drive the pressure filter plate to perform reciprocating lifting motion through connection. When the pressure filter plate moves downward, the pressure filter plate will press down and filter the pollutants in the space. The pressed pollutants will flow into the inner wall of the storage cavity during the downward pressing process of the pressure filter plate. Through this operation, the pollutants in the space can be recycled, which is convenient for later purification treatment work.

[0023] (4) During the upward movement of the pressure filter plate in the present invention, with the mutual movement of the screw rod and the pressure filter plate, the pressure filter plate will push the filtered water back to the filter holes. Finally, the filtered pool water will flow through the filter holes to the inner wall of the top box and be discharged through the water outlet pipe at last. This operation can further collect the water in the space and achieve the effect of recycling and utilization.

[0024] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Example 1, please refer to Figure 1 - Figure 4 As shown, the present invention is a water quality purification device for a Macrobrachium rosenbergii breeding pond, including an outer shell 1:

[0040] A drum 2, the drum 2 is rotatably connected to the inner wall of the outer shell 1. A water inlet pipe 101 is arranged at the bottom of the outer shell 1. A plurality of grooves 201 are circumferentially arranged on the inner wall of the drum 2. A filter belt 204 is arranged on the inner wall of the groove 201. A plurality of filter baffles 205 are circumferentially hinged on the outer wall of the filter belt 204;

[0041] Scraper plates 5, a plurality of scraper plates 5 are circumferentially arranged on the inner wall of the outer shell 1 and are located at one end close to the filter baffle 205. A plurality of impact plates 503 are hinged on the outer walls of the plurality of scraper plates 5. A plurality of spring frames 6 are circumferentially arranged on the inner wall of the outer shell 1 and are located at one end close to the scraper plates 5. A spring rod 601 is slidably connected to the inner wall of the spring frame 6;

[0042] Screw rods 7, two screw rods 7 are symmetrically arranged on the inner wall of the outer shell 1 and are located at one end far from the scraper plates 5. A filter press plate 702 is threadedly connected to the outer surface of the screw rod 7. The top of the outer shell 1 is fixedly connected to a top box 9. A water outlet pipe 903 is arranged at one end of the top box 9.

[0043] A connecting pipe 102 is rotatably connected to the bottom end of the outer shell 1. The inner wall of the connecting pipe 102 is rotatably connected to the outer wall of the water inlet pipe 101. The bottom end of the connecting pipe 102 extends out of the bottom end of the outer shell 1. A main transmission disc 401 is fixedly connected to the extending end of the connecting pipe 102. The top end of the connecting pipe 102 is fixedly connected to the bottom of the drum 2.

[0044] A transmission belt 403 is sleeved on the outer wall of the main transmission disc 401. A secondary transmission disc 402 is sleeved on the inner wall of the transmission belt 403 and at the end far from the main transmission disc 401. A motor 4 is fixedly connected to the bottom end of the secondary transmission disc 402.

[0045] It should be noted that during use, the drain of the breeding pond needs to be connected to the water inlet pipe 101. Then, the motor 4 is started. The motor 4 rotates the secondary transmission disc 402 by using the output end. The secondary transmission disc 402 drives the transmission belt 403 to rotate through connection. The transmission belt 403 then drives the main transmission disc 401 to rotate. When the main transmission disc 401 rotates, it will drive the connecting pipe 102 and the drum 2 to rotate. At this time, the pool water will enter the inner wall of the drum 2 through the water inlet pipe 101. The rotating drum 2 uses centrifugal force to fling the pool water to form a vortex. The vortex-shaped pool water will continuously beat against the outer walls of the filter belt 204 and the filter baffle 205. By using the interaction between the filter belt 204 and the filter baffle 205, the pollutants in the pool water are filtered.

[0046] Embodiment 2: Please refer to Figure 4 - Figure 6 As shown, the present invention is a water quality purification device for a Macrobrachium rosenbergii breeding pond. One end of the inner wall of the filter belt 204 is sleeved with a first transmission shaft 202, and the other end of the inner wall of the filter belt 204 is sleeved with a second transmission shaft 203. Both the first transmission shaft 202 and the second transmission shaft 203 are rotatably connected to the inner wall of the groove 201.

[0047] The top end of the first transmission shaft 202 extends out of the top end of the drum 2. A first gear 3 is fixedly connected to the extending end of the first transmission shaft 202. An internal gear 301 is arranged on the upper surface of the inner wall of the outer shell 1. The inner wall of the internal gear 301 meshes with the outer wall of the first gear 3.

[0048] It should be noted that when the drum 2 rotates, the drum 2 will drive the first transmission shaft 202 to perform circular rotation, and the first transmission shaft 202 drives the first gear 3 to perform circular motion. When the first gear 3 performs circular motion, it will continuously engage with the inner wall of the internal teeth 301, and at the same time realize the rotation circle of the first gear 3 itself. The first gear 3 rotates while performing circular motion. The first gear 3 drives the first transmission shaft 202 to rotate, and the first transmission shaft 202 drives the filter belt 204 and the filter baffle 205 to rotate through connection. At this time, the filter belt 204 and the filter baffle 205 will also perform circular rotation motion while performing their own rotational transmission. Under the continuous movement of the filter belt 204 and the filter baffle 205, the filter belt 204 and the filter baffle 205 will filter the pool water by rotation.

[0049] A number of connecting shafts 501 are arranged around the inner wall of the housing 1 and at one end close to the filter baffle 205. The outer wall of the connecting shaft 501 is rotatably connected to one end of the scraping plate 5 away from the filter baffle 205. A water flow groove 502 is arranged on the inner wall of the scraping plate 5. One end of the spring rod 601 close to the scraping plate 5 is rotatably connected to a roller 602.

[0050] It should be noted that when the scraping plate 5 scrapes the filter baffle 205, the scraping plate 5 will be pushed by the movement of the filter belt 204. When the scraping plate 5 is pushed, it will squeeze the spring rod 601 and the roller 602. When the scraping plate 5 leaves the filter belt 204, the spring rod 601 pushes the scraping plate 5 back to its original position, and the scraping plate 5 drives the impact plate 503 back to its original position. The impact plate 503 will hit the scraping plate 5 by inertia and at the same time pat off the pollutants on the surface of the scraping plate 5.

[0051] Embodiment 3: Please refer to Figures 1 - 10 As shown in the figure, the present invention is a water quality purification device for a Macrobrachium rosenbergii breeding pond. A number of fixing blocks 701 are fixedly connected to the inner wall of the housing 1 and at one end away from the scraping plate 5. The inner walls of the a number of fixing blocks 701 are rotatably connected to both ends of the screw rod 7. The top end of the screw rod 7 extends out of the top end of one of the fixing blocks 701. A number of guide rods 703 are slidably connected to the inner wall of the pressure filter plate 702 and at one end away from the screw rod 7. Both ends of the a number of guide rods 703 are fixedly connected to the inner wall of the housing 1.

[0052] External teeth 705 are arranged at the top edge of the drum 2. A second gear 704 is fixedly connected to the extended end of the screw rod 7. The outer wall of the second gear 704 is engaged with the outer wall of the external teeth 705. A storage cavity 8 is arranged at the bottom of the inner wall of the housing 1. A collection tank 801 is arranged at the top of the storage cavity 8. A spring 706 is sleeved on the outer wall of the screw rod 7 and at one end close to the collection tank 801. The top of the spring 706 is fixedly connected to a pressure plate 708. The inner wall of the pressure plate 708 is slidably connected to the outer wall of the screw rod 7.

[0053] It should be noted that when the drum 2 rotates, the external teeth 706 at the top of the drum 2 will rotate. The external teeth 705 drive the second gear 704 to rotate through meshing. The second gear 704 drives the screw rod 7 to rotate. The screw rod 7 drives the filter pressing plate 702 to perform a reciprocating lifting motion through a threaded connection. When the filter pressing plate 702 moves, it will further filter the pollutants in the interval space. When the filter pressing plate 702 presses down to the top of the pressure plate 708, the pressure plate 708 squeezes the spring 706 under force. At the same time, the pressure plate 708 drives the articulated rod 707 to press down the blocking plate 803. The blocking plate 803 drives the third gear 802 to flip under force. A number of third gears 802 flip synchronously through meshing, and at the same time, the storage cavity 8 is unfolded.

[0054] A number of third gears 802 are provided on the inner wall of the collection tank 801. A number of third gears 802 mesh with each other. A number of blocking plates 803 are fixedly connected to the outer walls of a number of third gears 802. The outer walls of a number of blocking plates 803 are sleeved with the inner wall of the collection tank 801. The top ends of a number of blocking plates 803 are hinged with a number of articulated rods 707. The top ends of a number of articulated rods 707 are hinged with the bottom end of the pressure plate 708.

[0055] A filter pipe 901 is provided at the connection between the top box 9 and the drum 2. A filter screen 904 is provided on the inner wall of the filter pipe 901. A number of filter holes 902 are provided around the connection between the top box 9 and the outer shell 1. A number of filter holes 902 are connected to the inner wall of the outer shell 1 in a penetrating manner.

[0056] It should be noted that the filter pressing plate 702 will store the filtered pollutants in the inner wall of the storage cavity 8 by unfolding the collection tank 801. When the filter pressing plate 702 moves upward, the spring 706 will spring the pressure plate 708. The pressure plate 708 drives the articulated rod 707 to return to its position and drives the blocking plate 803 to return to its original position to continue blocking the collection tank 801. During the upward movement of the filter pressing plate 702, the filtered water will be pushed back to the position of the filter hole 902. The water flows through the filter hole 902 to the top box 9. At the same time, the water filtered by the inner wall of the drum 2 will reach the inner wall of the top box 9 through the filter screen 904. Finally, the filtered water will be discharged through the water outlet pipe 903.

[0057] A specific application of this embodiment is as follows: During use, it is necessary to connect the drainage pipe of the breeding pond to the water inlet pipe 101. Then, start the motor 4. The motor 4 drives the secondary transmission disk 402 through the rotating pair at the output end. The secondary transmission disk 402 drives the transmission belt 403 to rotate through the connection. The transmission belt 403 then drives the main transmission disk 401 to rotate. When the main transmission disk 401 rotates, it drives the connecting pipe 102 and the drum 2 to rotate. At this time, the pool water will enter the inner wall of the drum 2 through the water inlet pipe 101. The rotating drum 2 uses centrifugal force to fling the pool water to form a vortex. The vortex-shaped pool water will continuously slap on the outer walls of the filter belt 204 and the filter baffle 205. By utilizing the interaction between the filter belt 204 and the filter baffle 205, the pollutants in the pool water are filtered and treated;

[0058] When the drum 2 rotates, the drum 2 drives the first transmission shaft 202 to perform circular rotation. The first transmission shaft 202 drives the first gear 3 to perform circular motion. When the first gear 3 performs circular motion, it continuously meshes with the inner wall of the internal gear 301, and at the same time realizes the rotation circle of the first gear 3 itself. The first gear 3 rotates while performing circular motion. The first gear 3 drives the first transmission shaft 202 to rotate. The first transmission shaft 202 drives the filter belt 204 and the filter baffle 205 to rotate through the connection. At this time, the filter belt 204 and the filter baffle 205 will also perform circular rotation motion while performing their own rotational transmission. Under the continuous movement of the filter belt 204 and the filter baffle 205, the filter belt 204 and the filter baffle 205 will filter and treat the pool water by means of rotation;

[0059] When one end of the filter belt 204 and the filter baffle 205 rotates out of the outer wall of the drum 2, the filter belt 204 and the filter baffle 205 in circular motion will intermittently contact one end of the scraping plate 5. The scraping plate 5 will squeeze and push the filter baffle 205. When the filter baffle 205 is scraped and squeezed, it will flip through the hinge. The pollutants filtered by the filter baffle 205 will be peeled off into the space between the drum 2 and the outer shell 1 under the scraping of the scraping plate 5. At the same time, when the filter belt 204 performs circular motion, it will drive the water flow to flow in the same direction. The flowing water will push the impact plate 503 through the water chute 502;

[0060] When the scraping plate 5 scrapes the filter baffle 205, the scraping plate 5 will be pushed by the movement of the filter belt 204. When the scraping plate 5 is pushed, it will squeeze the spring rod 601 and the roller 602. When the scraping plate 5 leaves the filter belt 204, the spring rod 601 will push the scraping plate 5 back to its original position. The scraping plate 5 drives the impact plate 503 back to its original position. The impact plate 503 will strike the scraping plate 5 by inertia, and at the same time pat off the pollutants on the surface of the scraping plate 5;

[0061] When the drum 2 rotates, the external teeth 705 at the top of the drum 2 will rotate. The external teeth 705 drive the second gear 704 to rotate through meshing. The second gear 704 drives the screw rod 7 to rotate. The screw rod 7 drives the filter pressing plate 702 to perform a reciprocating lifting motion through threaded connection. When the filter pressing plate 702 moves, it will further filter the pollutants in the interval space. When the filter pressing plate 702 presses down to the top of the pressure plate 708, the pressure plate 708 squeezes the spring 706 under force. At the same time, the pressure plate 708 drives the articulated rod 707 to press down the blocking plate 803. The blocking plate 803 drives the third gear 802 to flip under force. A number of third gears 802 flip synchronously through meshing, and at the same time, the storage cavity 8 is unfolded. The filter pressing plate 702 will send the filtered pollutants into the inner wall of the storage cavity 8 through the unfolded collection groove 801 for storage. When the filter pressing plate 702 moves upward, the spring 706 will push the pressure plate 708. The pressure plate 708 drives the articulated rod 707 to return to its position and drives the blocking plate 803 back to its original position to continue blocking the collection groove 801. During the upward movement of the filter pressing plate 702, the filtered water will be pushed back to the position of the filter hole 902. The water flows through the filter hole 902 to the top box 9. At the same time, the water filtered by the inner wall of the drum 2 will reach the inner wall of the top box 9 through the filter screen 904. Finally, the filtered water will be discharged through the water outlet pipe 903.
