Description

Technical Field

[0001] This utility model relates to the field of agricultural ecological aquaculture and water resource utilization technology, specifically a rice-shrimp co-culture water circulation device. Background Technology

[0002] Rice-shrimp co-culture, as an eco-friendly and cost-effective agricultural production model, has developed rapidly in recent years. In rice-shrimp co-culture systems, water circulation devices play a crucial role in maintaining a good water quality environment, and activated carbon, as an important water purification material, is widely used in these devices.

[0003] The adsorption performance of activated carbon particles within existing adsorption chambers varies. In most water circulation devices, the filling method of activated carbon within the chamber is rather simple and arbitrary, lacking a reasonable layout plan. When water flows through, due to uneven water flow distribution, some areas of activated carbon particles are in contact with water for too long, resulting in over-adsorption and premature saturation, thus losing their adsorption capacity; while in other areas, the activated carbon particles fail to effectively exert their adsorption function due to insufficient contact with water. Utility Model Content

[0004] The purpose of this invention is to provide a rice-shrimp co-culture water circulation device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a rice-shrimp co-culture water circulation device, including a box body, a servo motor installed on the top of the box body, a rotating rod installed on the drive end of the servo motor, the bottom end of the rotating rod being rotatably connected to the inner bottom wall of the box body, and multiple fixing rods installed on the outer wall of the rotating rod; a stirring blade fixedly installed on the other end of the fixing rod, the stirring blade having a notch recessed towards the rotating rod; two baffles symmetrically installed on the stirring blade, arranged in a figure-eight shape, with the wider opening facing the direction of rotation, and multiple partition strips fixedly installed between the two baffles, the partition strips being triangular in shape, with their tips aligned with the direction of the wider opening.

[0006] Furthermore, a connecting rod and a connecting rod are fixedly installed on the stirring blade, and the inner wall and bottom wall of the box are provided with sliding grooves that are adapted to the connecting rod and the connecting rod.

[0007] Furthermore, multiple mounting rods are fixedly installed on the inner bottom wall of the housing, and mounting cylinders are fixedly installed on the top of the mounting rods. Screwdriver blades are fixedly installed on the outer wall of the rotating rod, and the mounting cylinders are sleeved on the outer wall of the screwdriver blades.

[0008] Furthermore, a second water pipe is installed on the top of the box, and a filter box is fixedly installed at the other end of the second water pipe. A first water pipe is installed on the outer wall of the filter box.

[0009] Furthermore, a first filter screen is installed on the first water pipe, and a receiving pipe is installed at the bottom of the first water pipe near the first filter screen, with a sealing cap threaded to the bottom end of the receiving pipe.

[0010] Furthermore, multiple filter frames are inserted inside the filter box, and the filter frames are arranged linearly in sequence.

[0011] Furthermore, a rubber layer is integrally formed on the filter frame, and the rubber layer abuts against the filter box.

[0012] Furthermore, a third pipe is installed on the side of the box near the bottom, and a circulating water pump is fixedly installed on the third pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this invention, starting the servo motor causes the drive end to rotate the rotating rod. The fixed rod on the outer wall of the rotating rod rotates with it, causing the stirring blade to rotate. The stirring blade pushes the activated carbon to move, causing it to dynamically distribute and change its orientation within the chamber. The separator strip can break up accumulated and caking activated carbon. The stirring of the stirring blade and the V-shaped baffle prevents the activated carbon from accumulating and caking, maintaining the gaps between particles and extending its service life. The pushed activated carbon is scattered throughout the chamber by gravity through the notch. The V-shaped baffle helps to push the activated carbon, allowing it to move more widely. The triangular separator strip is fixed between the two baffles, with its tip facing the same direction as the wide opening. This movement ensures that the activated carbon moves evenly, maintaining relative movement between particles, preventing accumulation and caking, maintaining gaps, solving the problems of uneven water flow and insufficient contact, and allowing the activated carbon to fully exert its adsorption effect.

[0015] 2. In this utility model, the auger conveyor conveys the activated carbon from bottom to top, which enables the activated carbon to form a dynamic filtration process in the box. Compared with static placement, it increases the contact area and contact time between the activated carbon and water. The stirring blades agitate the activated carbon, making the flow path of the activated carbon in the box more complex, so that impurities in the water can come into more full contact with the activated carbon, improving the adsorption efficiency and better removing organic matter, pigments, odors and other substances from the water.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] See Figures 1-4 As shown, a rice-shrimp co-culture water circulation device includes a housing 1, a servo motor 2 installed on the top of the housing 1, a rotating rod 3 installed on the drive end of the servo motor 2, the bottom end of the rotating rod 3 being rotatably connected to the inner bottom wall of the housing 1, and multiple fixing rods installed on the outer wall of the rotating rod 3; a stirring blade 4 fixedly installed on the other end of the fixing rod, and a notch 7 recessed towards the rotating rod 3 on the stirring blade 4; two baffles 5 symmetrically installed on the stirring blade 4, arranged in a figure-eight shape, with the wider opening facing the direction of rotation, and multiple partition strips 6 fixedly installed between the two baffles 5, the partition strips 6 being triangular in shape, with their tips aligned with the direction of the wider opening.

[0024] After the servo motor 2 is started, the motor drive end drives the rotating rod 3 to rotate. The bottom end of the rotating rod 3 is rotatably connected to the bottom wall of the box 1, ensuring the stability of the rotating rod 3 during rotation. The fixed rod on the outer wall of the rotating rod 3 will rotate together with the rotating rod 3, thereby driving the stirring blade 4, which is fixedly installed at the other end of the fixed rod, to rotate.

[0025] The recessed notch 7 on the stirring blade 4, facing the rotating rod 3, plays a crucial role when the stirring blade 4 rotates. During rotation, the stirring blade 4 directly propels the activated carbon, causing the activated carbon particles to be dynamically distributed within the housing 1. As the stirring blade 4 moves the activated carbon, it changes its orientation. The separator strip 6 breaks up any accumulated or caked activated carbon particles. The agitation by the stirring blade 4 and the V-shaped baffle 5 prevents the activated carbon from accumulating and caked within the filter barrel, maintaining the gaps between the activated carbon particles, preserving good water permeability and air permeability, and extending the service life of the activated carbon. During this movement, the propelled activated carbon particles, due to gravity, will scatter through the recess 7 to various parts of the housing 1.

[0026] Simultaneously, symmetrically mounted V-shaped baffles 5 on the stirring blades 4, with their wide openings facing the direction of rotation, help propel the activated carbon particles as the stirring blades 4 rotate, allowing the activated carbon to move more widely. Meanwhile, triangular separators 6, fixedly installed between the two baffles 5, have their tips aligned with the wide openings. This complex movement of the activated carbon allows it to move evenly throughout the chamber 1, maintaining relative motion between the particles and preventing accumulation and caking. This preserves the gaps between the activated carbon particles, solving the problems of uneven water distribution and insufficient contact between activated carbon and water, allowing the activated carbon to more fully exert its adsorption effect.

[0027] See Figure 2-3 A connecting rod 10 and a connecting rod 11 are fixedly installed on the stirring blade 4. The inner wall and the inner bottom wall of the box body 1 are provided with sliding grooves that are adapted to the connecting rod 10 and the connecting rod 11.

[0028] The chute can restrict the movement path of the connecting rod 10 and the connecting rod 11, thereby ensuring that the stirring blade 4 stirs according to a specific trajectory, making the stirring action more stable and regular, improving the stirring effect, and facilitating the full circulation and mixing of water.

[0029] The connecting rod 10, the connecting rod 11 and the slide groove are used to connect the stirring blade 4 to the housing 1, which provides additional support for the stirring blade 4, enhances the stability of the stirring blade 4 during rotation, reduces shaking and vibration, reduces noise and wear generated during operation of the device, and extends the service life of the device.

[0030] See Figure 2 Multiple mounting rods are fixedly installed on the inner bottom wall of the housing 1. Mounting cylinders 9 are fixedly installed on the top of the mounting rods. Screwdriver blades 8 are fixedly installed on the outer wall of the rotating rod 3. Mounting cylinders 9 are sleeved on the outer wall of the screwdriver blades 8.

[0031] The auger conveyor transports the activated carbon from bottom to top, enabling a dynamic filtration process within the housing 1. Compared to static placement, this increases the contact area and time between the activated carbon and water. The stirring blades 4 agitate the activated carbon, making its flow path within the housing 1 more complex. This allows impurities in the water to come into more thorough contact with the activated carbon, improving adsorption efficiency and better removing organic matter, pigments, odors, and other impurities from the water.

[0032] See Figure 1 A second water pipe 15 is installed on the top of the housing 1, and a filter box 14 is fixedly installed at the other end of the second water pipe 15. A first water pipe 12 is installed on the outer wall of the filter box 14.

[0033] Water from the tank 1 flows into the filter box 14 through the second water pipe 15. The filter box 14 filters and purifies impurities, feces, and residual feed in the water, removing harmful substances and suspended solids and improving water quality. The purified water then flows back into the circulation system through the first water pipe 12, providing a clean and healthy growth environment for rice-shrimp farming, reducing the probability of disease, and promoting the growth and reproduction of rice-shrimp.

[0034] Stable water circulation filtration helps maintain the ecological balance in rice-crayfish co-culture systems. Filtering out excess nutrients prevents eutrophication, avoids excessive algae growth, and maintains stable dissolved oxygen levels and pH levels, allowing rice and crayfish to grow in a suitable environment.

[0035] See Figure 1 A first filter screen 13 is installed on the first water pipe 12, and a receiving pipe is installed at the bottom of the first water pipe 12 near the first filter screen 13. A sealing cap is threaded to the bottom end of the receiving pipe.

[0036] The first filter screen 13 can perform the first filtration of the water flowing in from the filter box 14, intercepting any small impurities and particles that may remain in the water, further improving the cleanliness of the water and providing a better growth environment for rice and shrimp.

[0037] The receiving pipe is located below the first filter screen 13 and can collect impurities that fall from the first filter screen 13 or are washed down by the water flow. Over time, impurities will accumulate in the receiving pipe, preventing impurities from accumulating in the first water pipe 12, which would affect the water flow or reduce the filtration effect.

[0038] See Figure 1 The filter box 14 has multiple filter frames inserted inside, which are arranged in a linear sequence.

[0039] Since the filter frames are inserted into the filter box 14, each filter frame can be disassembled and installed independently. When a filter frame becomes clogged or damaged after a period of use, only that filter frame needs to be removed for cleaning or replacement, without affecting the normal operation of other filter frames, greatly reducing maintenance costs and difficulty.

[0040] The linear arrangement makes the status of each filter rack readily apparent, facilitating regular checks by staff. This allows for timely identification of which filter racks require cleaning or replacement, ensuring that filter box 14 is always in optimal working condition.

[0041] See Figure 1 The filter screen frame has an integrally formed rubber layer, which abuts against the filter box 14.

[0042] The rubber layer has good elasticity. When it comes into contact with the filter box 14, it fills the gap between the filter screen frame and the inner wall of the filter box 14, forming a tight seal. This effectively prevents water from flowing directly through the gaps without passing through the filter screen, ensuring that all water entering the filter box 14 is filtered through the filter screen frame, thereby improving the filtration effect and guaranteeing the quality of water purification.

[0043] A tight seal helps maintain stable filtration pressure during the filtration process. Water flows only through the filter mesh along the designed path, making the filtration process more stable and efficient. Without the sealing effect of the rubber layer, water leakage may occur, leading to unstable filtration pressure and affecting filtration efficiency and effectiveness.

[0044] See Figure 1 A third pipe is installed on the side of the box 1 near the bottom, and a circulating water pump 16 is fixedly installed on the third pipe.

[0045] The circulating water pump 16 provides the power for water circulation, drawing water from the bottom of tank 1 through the third pipe and allowing it to participate in the entire water circulation system. This breaks the stagnant state of the water, promotes continuous water flow within tank 1, and forms a good water circulation.

[0046] The third pipe is installed near the bottom of tank 1 because the water at the bottom often contains more impurities, feces, and sediment. By using the circulating water pump 16 to extract the water from the bottom, and then filtering and treating it before returning it to tank 1, the water exchange rate can be accelerated, resulting in more effective improvement in water quality.

[0047] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
