Description

Technical Field

[0001] This utility model mainly relates to the field of rice planting water purification technology, specifically to a rice planting water purification, filtration and disinfection device for a rice-shrimp co-cultivation system. Background Technology

[0002] In the rice-crayfish integrated farming system, the water body serves as both the medium for rice growth and the habitat for crayfish. The farming water is rich in suspended impurities such as uneaten feed, excrement, algae, and organic debris, requiring filtration and disinfection equipment to maintain water quality.

[0003] Currently, most commonly used water purification equipment uses fixed filter frames. However, there are many suspended impurities in aquaculture water, and the filter frames will quickly become full of suspended impurities. Therefore, it is necessary to frequently disassemble and process the suspended impurities collected in the filter frames, and clean the filter frames by manual brushing or high-pressure water gun rinsing. The whole process is not only labor-intensive, but also affects the efficiency of aquaculture water filtration and disinfection. Utility Model Content

[0004] 1. The technical problem to be solved by the utility model:

[0005] This utility model provides a water purification, filtration and disinfection device for rice cultivation in a rice-shrimp co-cultivation system, in order to solve the technical problems existing in the background art.

[0006] 2. Technical Solution:

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows: a rice planting water purification, filtration and disinfection device for a rice-shrimp co-cultivation system, comprising a filter box, wherein a cleaning unit, a filter frame and a detachable slag collection frame are arranged sequentially from top to bottom in the filter box, wherein the filter frame is connected to a flipping mechanism that drives it to flip.

[0008] The filter box is connected to a water inlet pipe on one side, and the outlet of the water inlet pipe is located between the cleaning unit and the filter frame. The bottom of the filter box is connected to the water inlet of the water pump through a drain pipe. The outlet of the water pump can be selectively connected to the water inlet of the cleaning unit or the purification box through a multi-port pipe assembly.

[0009] The purification box is equipped with an outlet pipe at the bottom, and its interior is filled from top to bottom with a rice husk activated carbon layer, a porous biological carrier filler layer, and a microporous nanofiltration membrane layer.

[0010] Furthermore, the cleaning unit includes several horizontally and equidistantly arranged cleaning branch pipes, which are connected to each other by connecting pipes, and each cleaning branch pipe has multiple spray heads evenly arranged at its bottom along its length.

[0011] Furthermore, the multi-channel pipe assembly includes a first pipe, one end of which is connected to the outlet of the water pump, and the other end is connected to a second pipe through a first valve. The other end of the second pipe is connected to one of the cleaning branch pipes. A third pipe is connected to one side of the first pipe, and the other end of the third pipe is connected to a fourth pipe through a second valve. The other end of the fourth pipe extends to the inlet of the purification tank.

[0012] Furthermore, the flipping mechanism includes two rotating shafts, which are symmetrically fixed on both sides of the filter frame and rotatably connected to the side wall of the filter box. One of the rotating shafts extends to the outside of the filter box and is fixed with a worm gear. The worm gear meshes with a worm, which is mounted on the outer wall of the filter box through a bearing seat, and one end of the worm is provided with a drive handle.

[0013] Furthermore, a loading and unloading port matching the slag collection frame is provided on one side wall of the filter box, and guide rails are provided on both sides of the loading and unloading port on the inner wall of the filter box, and guide grooves corresponding to the guide rails are provided on the outer wall of the slag collection frame.

[0014] Furthermore, the bottom of the slag collection frame is provided with several evenly distributed drainage micro-holes.

[0015] 3. Beneficial effects:

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages: When there are too many suspended impurities collected in the filter frame, the filter box is rotated 180 degrees by the flipping mechanism, and the suspended impurities collected inside can be poured into the slag collection frame by gravity. Then, the filter frame is rinsed by the cleaning unit to prevent it from clogging. Thus, the collection and rinsing of suspended impurities inside the filter frame are achieved without disassembling the filter frame, which reduces labor costs and improves the efficiency of aquaculture water filtration and disinfection.

[0028] See attached document Figure 1-5 A water purification, filtration, and disinfection device for rice cultivation in a rice-shrimp co-cultivation system includes a filter box 1. The filter box 1 contains, from top to bottom, a cleaning unit 2, a filter frame 3, and a detachable slag collection frame 4. The filter frame 3 is connected to a flipping mechanism 5 that drives it to flip. One side of the filter box 1 is connected to a water inlet pipe 6, the outlet of which is located between the cleaning unit 2 and the filter frame 3. The bottom of the filter box 1 is connected to the inlet of a water pump 8 via a drain pipe 7. The outlet of the water pump 8 can be selectively connected to the inlet of either the cleaning unit 2 or the purification box 10 via a multi-port pipe assembly 9. The purification box 10 has an outlet pipe 11 at its bottom, and its interior is filled from top to bottom with a rice husk activated carbon layer 12, a porous biological carrier filler layer 13, and a microporous nanofiltration membrane layer 14.

[0029] In this embodiment, after the aquaculture water enters the filter box 1 through the inlet pipe 6, the suspended impurities in the water are first filtered through the filter frame 3, and then the water is pumped by the water pump 8 in conjunction with the drain pipe 7. Then it is transported to the purification box 10 by the multi-channel pipe assembly 9, and then filtered and purified through the rice husk activated carbon layer 12, the porous biological carrier filler layer 13 and the microporous nano filter membrane layer 14 in sequence, and finally discharged through the outlet pipe 11.

[0030] When too much suspended impurity is collected in the filter frame 3, the flipping mechanism 5 drives the filter box 1 to flip 180 degrees, and the suspended impurities collected inside are poured into the slag collection frame 4 by gravity. Then, the water pump 8 and the drain pipe 7 suck up the filtered water in the filter box 1 and transport it to the cleaning unit 2 through the multi-channel pipe assembly 9 to flush the filter frame 3 and prevent it from clogging. Thus, the collection and flushing of suspended impurities inside the filter frame 3 are achieved without disassembling the filter frame 3, which reduces labor costs and improves the efficiency of aquaculture water filtration and disinfection.

[0031] The cleaning unit 2 includes several horizontally and equidistantly arranged cleaning branch pipes 201. Adjacent cleaning branch pipes 201 are connected by connecting pipes 202. Each cleaning branch pipe 201 has multiple spray heads 203 evenly arranged at its bottom along its length. The multi-channel pipe assembly 9 includes a first pipe 901. One end of the first pipe 901 is connected to the outlet of the water pump 8, and the other end is connected to a second pipe 903 through a first valve 902. The other end of the second pipe 903 is connected to one of the cleaning branch pipes 201. A third pipe 904 is connected to one side of the first pipe 901. The other end of the third pipe 904 is connected to a fourth pipe 906 through a second valve 905. The other end of the fourth pipe 906 extends to the inlet of the purification box 10.

[0032] In this embodiment, when the first valve 902 is opened and the second valve 905 is closed, the water pump 8 is started and the water filtered in the filter box 1 is drawn out by the drain pipe 7. It will be transported to one of the cleaning branch pipes 201 through the first pipe 901 and the second pipe 903, and then transported to each cleaning branch pipe 201 through the connecting pipe 202. The filter frame 3 can then be rinsed by the spray head 203.

[0033] When the first valve 902 is closed and the second valve 905 is opened, the water pump 8 is started and, together with the drain pipe 7, can draw out the filtered water from the filter box 1. The water will then be transported to the purification box 10 for filtration and purification through the first pipe 901, the third pipe 904 and the fourth pipe 906.

[0034] The flipping mechanism 5 includes two rotating shafts 501, which are symmetrically fixed on both sides of the filter frame 3 and rotatably connected to the side wall of the filter box 1. One of the rotating shafts 501 extends to the outside of the filter box 1 and is fixed with a worm gear 502. The worm gear 502 meshes with a worm 503. The worm 503 is installed on the outer wall of the filter box 1 through a bearing seat 504, and one end of the worm gear 503 is provided with a drive handle 505.

[0035] In this embodiment, after holding the drive handle 505 and rotating it to the worm gear 503, it can engage with the worm wheel 502 to drive the corresponding rotating shaft 501 to rotate, thereby realizing the flipping of the filter frame 3.

[0036] The filter box 1 has a loading and unloading port 101 on one side wall that matches the slag collection frame 4. The inner wall of the filter box 1 is provided with guide rails 15 on both sides of the loading and unloading port 101. The outer wall of the slag collection frame 4 is provided with guide grooves 401 that slide in cooperation with the guide rails 15. The bottom of the slag collection frame 4 is provided with several evenly distributed drainage microholes 402.

[0037] In this embodiment, after the slag collection frame 4 is inserted along the loading and unloading port 101, the slag collection frame 4 can be installed into the filter box 1 through the sliding cooperation between the guide rail 15 and the guide groove 401. When the slag collection frame 4 collects suspended impurities, excess water can be discharged through the drainage microhole 402.

[0038] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.

[0039] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art.
