Description

Technical Field

[0001] The invention relates to the technical field of sewage filtering equipment, in particular to water purification equipment for a Macrobrachium rosenbergii breeding pond. Background Art

[0002] During the breeding process of Macrobrachium rosenbergii, water purification is the core technology for maintaining a good water environment, which directly affects the survival rate and growth rate of shrimp fry.

[0003] During the long-term use of the Macrobrachium rosenbergii breeding pond, pollutants such as residual bait and feces will accumulate at the bottom of the shrimp breeding pond. The long-term accumulation of these pollutants will affect the breeding and survival of Macrobrachium rosenbergii. For this reason, general farmers will use a filtering device with a straw at one end and a filter plate at the other end to filter the pollutants at the bottom of the breeding pond. Since sludge and shrimp shells will accumulate at the bottom of the shrimp breeding pond after long-term use, the sludge and shrimp shells will be blocked by the filtering component in the process of passing through the filtering component. The blockage will cause the filtering component to reduce the purification efficiency of the residual bait and feces, resulting in the inability to effectively filter and purify the shrimp breeding pond, thereby affecting the survival conditions of Macrobrachium rosenbergii.

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

[0020] (1) The present invention is provided with a drum inside, and a plurality of 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 the sludge, leftover bait and feces in the pool water by using its transmission. Under the continuous centrifugal swing of the drum, the sludge, leftover 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 outlet pipe.

[0021] (2) The present invention is provided with a scraping plate. After the filter belt and the filter baffle filter the pollutants in the pool water, the filter belt and the drum will continue to perform circular motions in opposite directions at a constant speed on the inner wall of the shell. At the same time, when the filter belt and the drum perform circular motions, the filter belt will contact and scrape 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 shell. At this time, after scraping and cleaning, the filter baffle will then return to the inner wall of the drum to perform filtering work. Through this design, the filter baffle can be cyclically cleaned to prevent the problem of filter blockage.

[0022] (3) The present invention is provided with a filter press plate inside. When the drum is rotating, the drum drives the spiral rod to rotate through linkage. When the spiral rod rotates, it drives the filter press plate to perform reciprocating lifting and lowering motions through connection. When the filter press plate is descending, the filter press plate presses down the pollutants in the interval space and filters them. The pressed pollutants flow into the inner wall of the storage chamber during the process of the filter press plate being pressed down. Through this operation, the pollutants in the interval space can be recovered, which can facilitate the subsequent purification treatment work.

[0023] (4) In the process of the filter press plate rising, the filter press plate pushes the filtered water back to the filter holes with the help of the mutual movement of the spiral rod and the filter press plate. Finally, the filtered pool water flows through the filter holes to the inner wall of the top box and is finally discharged through the outlet pipe. This operation can further collect the water inside the interval space to achieve the effect of recycling.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention.

[0039] For example 1, please refer to Figure 1 - Figure 4 As shown, the present invention is a water purification device for a Macrobrachium rosenbergii breeding pond, comprising a housing 1:

[0040] The drum 2 is rotatably connected to the inner wall of the housing 1. A water inlet pipe 101 is provided at the bottom of the housing 1. A plurality of grooves 201 are provided around the inner wall of the drum 2. A filter belt 204 is provided on the inner wall of the groove 201. A plurality of filter baffles 205 are hinged around the outer wall of the filter belt 204.

[0041] Scraping plates 5, several of which are arranged around the inner wall of the housing 1 and located near one end of the filter baffle 205, and several impact plates 503 are hingedly connected to the outer walls of the several scraping plates 5. Several spring frames 6 are arranged around the inner wall of the housing 1 and located near one end of the scraping plates 5, and the inner wall of the spring frame 6 is slidably connected to a spring rod 601;

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

[0044] The outer wall of the main transmission disc 401 is provided with a transmission belt 403 , and the inner wall of the transmission belt 403 and the end away from the main transmission disc 401 are provided with an auxiliary transmission disc 402 , and the bottom end of the auxiliary transmission disc 402 is fixedly connected to the motor 4 .

[0045] It should be noted that when in use, the drainage of the breeding pool needs to be connected to the water inlet pipe 101, and then the motor 4 is started. The motor 4 uses the output end to rotate the auxiliary transmission disc 402, and the auxiliary transmission disc 402 drives the transmission belt 403 to rotate through the connection, and 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 rotation of the drum 2 swings the pool water through centrifugal force to form a vortex. The pool water in the vortex state will continue to slap the outer wall of the filter belt 204 and the filter baffle 205, and the interaction between the filter belt 204 and the filter baffle 205 is used to filter and treat the pollutants in the pool water.

[0046] Example 2: Please refer to Figure 4 - Figure 6 As shown, the present invention is a water purification device for a Macrobrachium rosenbergii breeding pond. A transmission shaft 1 202 is sleeved on one end of the inner wall of the filter belt 204, and a transmission shaft 2 203 is sleeved on the other end of the inner wall of the filter belt 204. The transmission shaft 1 202 and the transmission shaft 2 203 are both rotatably connected to the inner wall of the groove 201.

[0047] The top end of the transmission shaft 202 extends out of the top end of the drum 2, and the extended end of the transmission shaft 202 is fixedly connected to the gear 3. The upper surface of the inner wall of the shell 1 is provided with internal teeth 301, and the inner wall of the internal teeth 301 is engaged with the outer wall of the gear 3.

[0048] It should be noted that when the drum 2 is rotating, the drum 2 will drive the transmission shaft 202 to rotate in a circular motion, and the transmission shaft 202 will drive the gear 3 to perform a circular motion. The gear 3 will continue to engage with the inner wall of the inner tooth 301 during the circular motion, and at the same time realize the rotation circle of the gear 3 itself. The gear 3 rotates while performing a circular motion, and the gear 3 drives the transmission shaft 202 to rotate. The 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 a circular rotation while performing their own rotation transmission. Under the continuous motion of the filter belt 204 and the filter baffle 205, the filter belt 204 and the filter baffle 205 will use rotation to filter the pool water.

[0049] Several connecting shafts 501 are arranged around the inner wall of the shell 1 and located at one end close to the filter baffle 205. The outer wall of the connecting shaft 501 is rotatably connected to the end of the scraping plate 5 away from the filter baffle 205. The inner wall of the scraping plate 5 is provided with a water flow groove 502, and the end of the spring rod 601 close to the scraping plate 5 is rotatably connected to the 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, and the scraping plate 5 will be squeezed by 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 to return to its original position. The impact plate 503 uses inertia to hit the scraping plate 5, and at the same time, the pollutants on the surface of the scraping plate 5 are knocked away.

[0051] Example 3: Please refer to Figures 1-10 As shown, the present invention is a water purification device for a Macrobrachium rosenbergii breeding pond. A plurality of fixed blocks 701 are fixedly connected to the inner wall of the outer shell 1 and located at the end away from the scraping plate 5. The inner walls of the plurality of fixed blocks 701 are rotatably connected to the two ends of the spiral rod 7. The top of the spiral rod 7 extends from the top of one of the fixed blocks 701. The inner wall of the filter press plate 702 and located at the end away from the spiral rod 7 are slidably connected to a plurality of guide rods 703. The two ends of the plurality of guide rods 703 are fixedly connected to the inner wall of the outer shell 1.

[0052] The top edge of the drum 2 is provided with external teeth 705, and the extended end of the screw rod 7 is fixedly connected to the gear 2 704, the outer wall of the gear 2 704 is meshed with the outer wall of the external teeth 705, and the bottom of the inner wall of the shell 1 is provided with a storage cavity 8, and the top of the storage cavity 8 is provided with a collection groove 801. The outer wall of the screw rod 7 and the end close to the collection groove 801 are sleeved with a spring 706, and the top of the spring 706 is fixedly connected to the pressure plate 708, and 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 is rotating, the outer teeth 705 on the top of the drum 2 will rotate, and the outer teeth 705 drive the gear 2 704 to rotate through meshing, and the gear 2 704 drives the screw rod 7 to rotate, and the screw rod 7 drives the filter press plate 702 to perform reciprocating lifting and lowering motion through a threaded connection. The filter press plate 702 will further filter the pollutants in the interval space during movement. When the filter press plate 702 is pressed down to the top of the pressure plate 708, the pressure plate 708 is forced to squeeze the spring 706. At the same time, the pressure plate 708 drives the hinged rod 707 to press down the sealing plate 803. The sealing plate 803 is forced to drive the gear three 802 to flip over. Several gear threes 802 are synchronously flipped through meshing, and the storage chamber 8 is expanded at the same time.

[0054] The inner wall of the collecting tank 801 is provided with several gear threes 802, and the several gear threes 802 are meshed with each other. The outer walls of the several gear threes 802 are fixedly connected with several sealing plates 803.

[0056] It should be noted that the filter press plate 702 will store the filtered pollutants through the expanded collection groove 801 into the inner wall of the storage chamber 8. When the filter press plate 702 moves upward, the spring 706 will bounce the pressure plate 708, and the pressure plate 708 will drive the hinged rod 707 to return to its position, and drive the sealing plate 803 back to its original position to continue to block the collection groove 801. During the upward movement of the filter press plate 702, the filtered water will be pushed back to the position of the filter hole 902, and the water will flow to the top box 9 through the filter hole 902. At the same time, the water filtered by the inner wall of the drum 2 will pass through the filter screen 904 to reach the inner wall of the top box 9, and finally the filtered water will be discharged through the outlet pipe 903.

[0057] A specific application of this embodiment is as follows: when in use, it is necessary to connect the drainage of the breeding pool to the water inlet pipe 101, then start the motor 4, the motor 4 uses the output end to rotate the auxiliary transmission disc 402, the auxiliary transmission disc 402 drives the transmission belt 403 to rotate through the connection, and the transmission belt 403 then drives the main transmission disc 401 to rotate, and the main transmission disc 401 will drive the connecting pipe 102 and the drum 2 to rotate when rotating. At this time, the pool water will enter the inner wall of the drum 2 through the water inlet pipe 101, and the rotation of the drum 2 will swing the pool water to form a vortex through the centrifugal force. The pool water in the vortex state will continuously hit the outer wall of the filter belt 204 and the filter baffle 205, and the interaction between the filter belt 204 and the filter baffle 205 will be used to filter the pollutants in the pool water;

[0058] When the drum 2 is rotating, the drum 2 will drive the transmission shaft 1 202 to rotate in a circular motion, and the transmission shaft 1 202 will drive the gear 1 3 to perform a circular motion. During the circular motion, the gear 1 3 will continuously mesh with the inner wall of the inner tooth 301, and at the same time realize the rotation circle of the gear 1 3 itself. The gear 1 3 rotates while performing a circular motion, and the gear 1 3 drives the transmission shaft 1 202 to rotate. The transmission shaft 1 202 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 a circular rotation while performing their own rotation transmission. Under the continuous motion of the filter belt 204 and the filter baffle 205, the filter belt 204 and the filter baffle 205 will use the rotation to filter the pool water;

[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 the circular motion will intermittently contact one end of the scraping plate 5, and 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 scraped by the scraping plate 5 and peeled off into the space between the drum 2 and the shell 1. At the same time, the filter belt 204 will drive the water flow in the same direction during the circular motion, and the flowing water will push the impact plate 503 through the water flow trough 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, and the scraping plate 5 will be squeezed by 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 to return to its original position. The impact plate 503 uses inertia to hit the scraping plate 5, and at the same time, the pollutants on the surface of the scraping plate 5 are knocked off.

[0061] When the drum 2 is rotating, the outer teeth 705 on the top of the drum 2 will rotate, and the outer teeth 705 will drive the gear 2 704 to rotate through meshing, and the gear 2 704 will drive the screw rod 7 to rotate, and the screw rod 7 will drive the filter press plate 702 to perform reciprocating lifting motion through a threaded connection. The filter press plate 702 will further filter the pollutants in the interval space during movement. When the filter press plate 702 is pressed down to the top of the pressure plate 708, the pressure plate 708 is forced to squeeze the spring 706. At the same time, the pressure plate 708 drives the hinged rod 707 to press the blocking plate 803. The blocking plate 803 is forced to drive the gear 3 802 to flip, and several gears 3 802 are synchronously flipped through meshing. The filter press plate 702 rotates and expands the storage chamber 8 at the same time. The filtered pollutants are stored in the inner wall of the storage chamber 8 through the expanded collection groove 801. When the filter press plate 702 moves upward, the spring 706 will rebound the pressure plate 708. The pressure plate 708 drives the hinge rod 707 to return to its position and drives the blocking plate 803 to return to its original position to continue to block the collection groove 801. During the upward movement of the filter press plate 702, the filtered water will be pushed back to the position of the filter hole 902. The water flows to the top box 9 through the filter hole 902. At the same time, the water filtered by the inner wall of the drum 2 will pass through the filter screen 904 to the inner wall of the top box 9. Finally, the filtered water will be discharged through the outlet pipe 903.
