Description

Technical Field

[0001] This invention relates to the field of floating bed technology, specifically to a waste composting composite biological matrix floating bed. Background Technology

[0002] Bio-based floating beds are artificial floating devices used for the ecological restoration of aquatic bodies. They are mainly used in the treatment of eutrophic water bodies such as rivers and lakes. Based on a floating carrier, they are combined with a special bio-based substrate and planted with aquatic plants. By utilizing the synergistic effect of plant absorption, substrate adsorption, and microbial degradation, pollutants such as nitrogen and phosphorus in the water are removed. The plant roots and the substrate together form a biofilm, which degrades organic matter and purifies water quality. It is a commonly used ecological treatment technology in water environment management.

[0003] Currently, traditional floating beds rely solely on the initial biological substrate to provide nutrients. The nutrients required for plant growth in the later stages are mostly supplemented by the artificial application of chemical fertilizers. This not only increases the operation and maintenance costs but also easily leads to a sharp increase in nitrogen and phosphorus concentrations in the water due to excessive fertilizer application, causing secondary eutrophication. To address this, we propose a waste-composted composite biological substrate floating bed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a waste-composted composite biological substrate floating bed, which solves the problem that existing floating beds rely solely on the initial biological substrate for nutrients, and the nutrients required for plant growth in the later stages are mostly supplemented by artificial chemical fertilizers. This not only increases operation and maintenance costs, but also easily leads to a sharp increase in nitrogen and phosphorus concentrations in the water due to excessive fertilizer application, causing secondary eutrophication.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a waste composting composite biological substrate floating bed, comprising a floating bed body, a carrier plate mounted on the surface of the floating bed body, a planting pot placed in the floating bed body, and permeable holes on the surfaces of both the floating bed body and the planting pot. A composting component is disposed on the surface of the floating bed body, the composting component comprising two composting boxes symmetrically mounted on the lower surface of the carrier plate, with the two composting boxes located on opposite sides of the floating bed body. Two symmetrically arranged feed inlets are fixedly connected to the upper surface of the carrier plate, the feed inlets communicating with the composting boxes. A conduit is mounted on the lower surface of the composting box. The end of the conduit furthest from the composting tank is connected to the floating bed. A one-way valve is installed on the conduit to transport the material in the composting tank unidirectionally into the floating bed. It integrates a dedicated composting component, which can directly feed, crush, and compost kitchen waste. The chopped waste is naturally composted into organic nutrient material in the composting tank, and then pushed to the floating bed by air pressure to fuse with the composite biological substrate, continuously supplying nutrients to the plants. This realizes the reuse of kitchen waste, which not only reduces the environmental pollution caused by the random discharge of waste, but also replaces traditional chemical fertilizers, reducing the cost of plant cultivation. At the same time, the organic nutrients are more in line with the plant growth needs, improving plant growth and the ecological restoration effect of the floating bed.

[0006] Preferably, a drive motor is installed on one side of the composting tank. The drive end of the drive motor is rotatably connected to the inner wall of the composting tank. The output end of the drive motor located in the composting tank is fixedly connected to a drive rod. Multiple equally spaced cutters are installed on the drive rod for chopping waste. After feeding, the drive motor drives the cutters to chop the waste at high speed, processing large pieces of material into fine particles, greatly increasing the contact area between waste and microorganisms, improving composting efficiency, and preventing large pieces of material from clogging the conveying channel. The composted material is conveyed directionally by air pressure pusher. With the help of a one-way valve on the guide pipe, the substrate and water in the floating bed can be effectively prevented from flowing back into the composting tank, avoiding contamination of the composted material or blockage of the conveying channel, and ensuring the continuity and stability of nutrient supply.

[0007] Preferably, the feed inlet is inverted L-shape and uses a horizontal feeding method. The inverted L-shaped horizontal feeding structure effectively prevents waste from spilling during feeding and improves the convenience of feeding operations. At the same time, the feed inlet is equipped with a sealing structure consisting of a pull block, a baffle, and a stabilizing spring. After feeding, the baffle can automatically reset and seal the feed inlet, which can prevent odors and gases from leaking out of the composting tank, improve the working environment, and prevent water and external debris from entering the composting tank, preventing the composted material from being contaminated and ensuring the smooth progress of the composting process. Moreover, the opening and resetting of the sealing structure are both simple manual operations, making it highly practical.

[0008] Preferably, a baffle is slidably connected to the inner wall of the feed inlet, which blocks the inside of the feed inlet. Two symmetrically arranged protrusions are installed on the side of the baffle near the floating bed body. A stabilizing spring is fixedly connected to the lower surface of the protrusion, and the lower end of the stabilizing spring is connected to the upper surface of the feed inlet. A pull block is fixedly connected to the side of the baffle away from the floating bed body. The pull block is located in front of the feed inlet. When waste is discharged, the pull block is pulled upward, which moves the baffle and opens the feed inlet. Waste is then discharged. After the discharge is completed, the pull block is released, and the stabilizing spring drives the baffle to reset, thus blocking the feed inlet.

[0009] Preferably, an air pump is installed on the upper surface of the feed inlet, and an air inlet pipe is installed at the input end of the air pump, and the air inlet pipe is curved.

[0010] Preferably, the air pump injects gas into the feed inlet, creating air pressure thrust inside the composting tank, which in turn pushes the composted material inside the composting tank through the conduit and one-way valve into the floating bed body, providing nutrients for the plants inside the floating bed body.

[0011] Preferably, a control box is installed on the lower surface of the carrier plate to control the operation of the air pump and the drive motor. The control box integrates a battery and a control unit. The control box can precisely regulate the start and stop of the air pump and the amount of air injected, so as to realize the on-demand adjustment of nutrient supply and adapt to the nutrient needs of different growth stages of the plant.

[0012] Preferably, the inner wall of the floating bed is fixedly connected to a horizontally placed support plate, and the inner wall of the floating bed is fixedly connected to two symmetrically arranged baffles. The two baffles are mirror images of each other with the support plate as the axis of symmetry. The edges of the planting pots are placed on the baffles and the support plate respectively. The support plate and the symmetrical baffles on the inner wall of the floating bed form a multi-layer support structure, providing initial placement and positioning for the planting pots. With the help of the positioning component's locking rods and locking sleeves, the double fixing structure can effectively prevent the planting pots from shifting or tipping over due to water sloshing, ensuring the stability of the plant root growth environment.

[0013] Preferably, the surface of the floating bed is provided with a positioning component, which includes a positioning sleeve installed on the upper surface of the floating bed. A locking rod is slidably connected to the inner wall of the positioning sleeve, and a control rod is installed at one end of the locking rod. A locking sleeve is installed on the upper surface of the planting pot, and one end of the locking rod is inserted into the locking rod for positioning the planting pot. The positioning component realizes quick unlocking and resetting of the locking rod through a handle and a positioning spring. When planting or removing plants, pulling the handle can complete the positioning and unlocking of the planting pot without complicated operations, greatly improving the convenience of planting, replacing and harvesting plants, and reducing the maintenance intensity of the floating bed.

[0014] Preferably, a handle is fixedly connected to the upper surface of the control rod, and two symmetrically arranged positioning blocks are installed on the lower surface of the control rod. A positioning spring is installed on one side of each positioning block, and the end of the positioning spring away from the positioning block is connected to the surface of the floating bed.

[0015] In summary, the technical effects and advantages of this invention are as follows:

[0016] 1. In this invention, a dedicated composting component is integrated, which can directly feed, crush, and compost kitchen waste. The chopped waste is naturally composted into organic nutrient materials in the composting box, and then pushed to the floating bed body by air pressure to integrate with the composite biological substrate, continuously supplying nutrients to the plants. This realizes the reuse of kitchen waste, which not only reduces the environmental pollution caused by the random discharge of waste, but also replaces traditional chemical fertilizers, reducing the cost of plant cultivation. At the same time, the organic nutrients are more in line with the plant growth needs, improving plant growth and the ecological restoration effect of the floating bed.

[0017] 2. In this invention, after feeding, the drive motor drives the cutter to shred the waste at high speed, processing large pieces of material into fine particles, greatly increasing the contact area between the waste and microorganisms, improving the composting efficiency, and preventing large pieces of material from clogging the conveying channel; the composted material is conveyed in a directional manner by air pressure push by an air pump, and with the one-way valve on the guide tube, it can effectively prevent the substrate and water in the floating bed from flowing back into the composting box, avoid contamination of the composted material or blockage of the conveying channel, ensure the continuity and stability of nutrient supply, and the control box can precisely control the start and stop of the air pump and the amount of air injected, realize the on-demand adjustment of nutrient supply, and adapt to the nutrient needs of different growth stages of plants.

[0018] 3. In this invention, the support plate and symmetrical baffles on the inner wall of the floating bed form a multi-layer support structure, providing initial placement and positioning for the planting pot. Combined with the locking rod and locking sleeve of the positioning component, the double-fixed structure effectively prevents the planting pot from shifting or tipping due to water sloshing, ensuring the stability of the plant root growth environment. The positioning component uses a handle and positioning spring to quickly unlock and reset the locking rod. When planting or removing plants, simply pulling the handle completes the positioning and unlocking of the planting pot, eliminating the need for complex operations and significantly improving the convenience of planting, replacing, and harvesting plants, while reducing the maintenance intensity of the floating bed.

[0019] 4. In this invention, the feed inlet adopts an inverted L-shaped horizontal feeding structure, which can effectively prevent waste from spilling during feeding and improve the convenience of feeding operation. At the same time, the feed inlet is equipped with a sealing structure consisting of a pull block, a baffle, and a stabilizing spring. After feeding, the baffle can automatically reset and seal the feed inlet, which can prevent odors and gases from leaking out of the composting box, improve the working environment, and prevent water and external debris from entering the composting box, preventing the composting material from being contaminated and ensuring the smooth progress of the composting process. Moreover, the opening and resetting of the sealing structure are both simple manual operations, making it highly practical. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] refer to Figures 1-8 The floating bed, a composite bio-based waste composting substrate, includes a floating bed body 1. A carrier plate 2 is mounted on the surface of the floating bed body 1. A planting pot 3 is placed inside the floating bed body 1. Both the floating bed body 1 and the planting pot 3 have permeable holes on their surfaces. A composting component 6 is provided on the surface of the floating bed body 1. The composting component 6 includes two composting boxes 61, which are symmetrically installed on the lower surface of the carrier plate 2 and located on opposite sides of the floating bed body 1. Two symmetrically arranged feed inlets 66 are fixedly connected to the upper surface of the carrier plate 2 and communicate with the composting boxes 61. A conduit 62 is installed on the lower surface of the composting box 61, with the conduit 62 located away from the composting box 61. The end is connected to the floating bed body 1. A one-way valve 63 is installed on the conduit 62 to transport the material in the composting box 61 to the interior of the floating bed body 1 in one direction. It integrates a dedicated composting component 6, which can directly feed, crush and compost kitchen waste. The chopped waste is naturally composted into organic nutrient material in the composting box 61, and then pushed to the floating bed body 1 by air pressure to integrate with the composite biological substrate, continuously supplying nutrients to the plants. This realizes the reuse of kitchen waste, which not only reduces the environmental pollution caused by the random discharge of waste, but also replaces traditional chemical fertilizers, reduces the cost of plant cultivation, and at the same time, the organic nutrients are more in line with the plant growth needs, improving the plant growth and the ecological restoration effect of the floating bed.

[0031] A drive motor 614 is installed on one side of the composting tank 61. The drive end of the drive motor 614 is rotatably connected to the inner wall of the composting tank 61. The output end of the drive motor 614 in the composting tank 61 is fixedly connected to a drive rod 612. Multiple equally spaced cutters 613 are installed on the drive rod 612 for chopping waste. After feeding, the drive motor 614 drives the cutters 613 to chop the waste at high speed, processing large pieces of material into fine particles, greatly increasing the contact area between waste and microorganisms, improving composting efficiency, and preventing large pieces of material from clogging the conveying channel. The composted material is pushed by the air pump 69 to achieve directional conveying. With the help of the one-way valve 63 on the guide pipe 62, the substrate and water in the floating bed 1 can be effectively prevented from flowing back to the composting tank 61, avoiding contamination of the composted material or blockage of the conveying channel, and ensuring the continuity and stability of nutrient supply.

[0032] The feed inlet 66 is an inverted L-shape, and the feed inlet 66 uses a horizontal feeding method. The inverted L-shaped horizontal feeding structure of the feed inlet 66 can effectively prevent waste from spilling during feeding and improve the convenience of feeding operation. At the same time, the feed inlet 66 is equipped with a sealing structure consisting of a pull block 611, a baffle 65, and a stabilizing spring 68. After feeding, the baffle 65 can automatically reset and seal the feed inlet 66, which can prevent odors and gases from leaking out of the composting tank 61, improve the working environment, and prevent water and external debris from entering the composting tank 61, preventing the composting material from being contaminated and ensuring the smooth progress of the composting process. Moreover, the opening and resetting of the sealing structure are all simple manual operations, which are highly practical.

[0033] The inner wall of the feed inlet 66 is slidably connected to a baffle 65, which blocks the inside of the feed inlet 66. Two symmetrically arranged protrusions 67 are installed on the side of the baffle 65 near the floating bed body 1. A stabilizing spring 68 is fixedly connected to the lower surface of the protrusion 67. The lower end of the stabilizing spring 68 is connected to the upper surface of the feed inlet 66. A pull block 611 is fixedly connected to the side of the baffle 65 away from the floating bed body 1. The pull block 611 is located in front of the feed inlet 66. When waste is disposed of, the pull block 611 is pulled upward, which causes the baffle 65 to move and the feed inlet 66 to open. Waste is then disposed of. After disposal, the pull block 611 is released, and the stabilizing spring 68 causes the baffle 65 to reset, thus blocking the feed inlet 66.

[0034] Among them, an air pump 69 is installed on the upper surface of the feed inlet 66, and an air inlet pipe 610 is installed at the input end of the air pump 69. The air inlet pipe 610 is curved.

[0035] The air pump 69 injects gas into the feed inlet 66, creating air pressure inside the composting box 61, which in turn pushes the composted material in the composting box 61 through the conduit 62 and the one-way valve 63 into the floating bed 1, providing nutrients for the plants in the floating bed 1.

[0036] The lower surface of the carrier plate 2 is equipped with a control box 64, which is used to control the operation of the air pump 69 and the drive motor 614. The control box 64 integrates a battery and a control unit. The control box 64 can precisely regulate the start and stop of the air pump 69 and the amount of air injected, so as to realize the on-demand adjustment of nutrient supply and adapt to the nutrient needs of different growth stages of the plant.

[0037] The inner wall of the floating bed 1 is fixedly connected to a horizontally placed support plate 4, and the inner wall of the floating bed 1 is fixedly connected to two symmetrically arranged baffles 5. The two baffles 5 are mirror images of each other with the support plate 4 as the axis of symmetry. The edges of the planting pot 3 are placed on the baffles 5 and the support plate 4 respectively. The support plate 4 and the symmetrical baffles 5 on the inner wall of the floating bed 1 form a multi-layer support structure, which provides initial placement and positioning for the planting pot 3. With the help of the positioning component 7, the locking rod 75 and the locking sleeve 77 are engaged and positioned. The double fixing structure can effectively prevent the planting pot 3 from shifting or tipping over due to water sloshing, and ensure the stability of the plant root growth environment.

[0038] The floating bed body 1 is provided with a positioning component 7, which includes a positioning sleeve 76. The positioning sleeve 76 is installed on the upper surface of the floating bed body 1. A locking rod 75 is slidably connected to the inner wall of the positioning sleeve 76. A control rod 71 is installed at one end of the locking rod 75. A locking sleeve 77 is installed on the upper surface of the planting pot 3. One end of the locking rod 75 is inserted into the locking rod 75 to position the planting pot 3. The positioning component 7 realizes the quick unlocking and resetting of the locking rod 75 through the handle 74 and the positioning spring 73. When planting or removing plants, pulling the handle 74 can complete the positioning and unlocking of the planting pot 3. No complicated operation is required, which greatly improves the convenience of planting, replacing and harvesting plants and reduces the maintenance intensity of the floating bed.

[0039] The upper surface of the control rod 71 is fixedly connected to a handle 74, and the lower surface of the control rod 71 is equipped with two symmetrically arranged positioning blocks 72. A positioning spring 73 is installed on one side of the positioning block 72, and the end of the positioning spring 73 away from the positioning block 72 is connected to the surface of the floating bed body 1.

[0040] Working principle of the invention: The support plate 4 and the symmetrical baffles 5 on the inner wall of the floating bed 1 form a multi-layer support structure. The edge of the planting pot 3 can be placed directly on the support plate 4 and the baffles 5 to achieve the initial placement and positioning of the planting pot 3. When installing the planting pot 3, pull the handle 74 away from the floating bed 1 to drive the control rod 71 and the locking rod 75 to slide. After the planting pot 3 is placed in place, release the handle 74. The elastic restoring force of the positioning spring 73 pushes the positioning block 72 and the control rod 71 to reset, so that the locking rod 75 is inserted into the locking sleeve 77 on the upper surface of the planting pot 3 to complete the precise positioning of the planting pot 3 and prevent the planting pot 3 from shifting or tipping due to water sloshing. When taking out the plant later, pull the handle 74 to unlock the locking rod 75 and take out the planting pot 3 and the plant conveniently.

[0041] When feeding material into the floating bed, pull the pull block 611 at the feed inlet 66 upwards, causing the baffle 65 to slide upwards along the inner wall of the feed inlet 66. The stabilizing spring 68 is stretched, and the internal channel of the feed inlet 66 is opened. Using the inverted L-shaped horizontal feeding structure of the feed inlet 66, kitchen waste is smoothly fed into the feed inlet 66, avoiding spillage of waste during feeding. After feeding is completed, release the pull block 611. The elastic restoring force of the stabilizing spring 68 causes the baffle 65 to quickly reset, resealing the feed inlet 66 to prevent odors and gases from leaking out of the composting tank 61, while also preventing water and debris from entering the composting tank 61.

[0042] After feeding is completed, the control unit inside the control box 64 starts the drive motor 614 on one side of the composting box 61. The drive end of the drive motor 614 drives the drive rod 612 inside the composting box 61 to rotate. Multiple equally spaced cutters 613 on the drive rod 612 rotate synchronously with the drive rod 612, and shred the kitchen waste falling into the composting box 61 from the feed port 66 at high speed, cutting large pieces of waste into small particles, increasing the contact area between waste and microorganisms, improving the composting efficiency of waste, and preventing large pieces of waste from clogging the subsequent conveying channel.

[0043] The shredded waste undergoes natural decomposition in the composting tank 61, forming organic nutrient material that can be absorbed by plants. When nutrients need to be supplied to the floating bed 1, the control box 64 controls the air pump 69 to start. The air pump 69 draws in external gas through the curved air inlet pipe 610 and continuously injects the gas into the feed inlet 66. After the gas enters the composting tank 61 through the feed inlet 66, a stable air pressure thrust is formed inside the composting tank 61. Under the action of air pressure, the decomposed material in the composting tank 61 moves towards the floating bed 1 along the guide pipe 62 on the lower surface of the composting tank 61. The one-way valve 63 on the guide pipe 62 only allows the material to flow unidirectionally from the composting tank 61 to the floating bed 1, effectively preventing the substrate and water in the floating bed 1 from flowing back to the composting tank 61, avoiding contamination of the composted material or blockage of the channel.

[0044] The decomposed material entering the floating bed 1 through the conduit 62 and one-way valve 63 integrates with the composite biological matrix inside the floating bed 1, providing continuous and sufficient organic nutrients for the roots of the plants in the planting pot 3, thus realizing the resource utilization of kitchen waste. The entire operation of the floating bed is centrally controlled by the control box 64 on the lower surface of the carrier plate 2. The battery integrated inside the control box 64 provides stable power to the air pump 69, drive motor 614 and other electrical control components. The control unit can precisely control the start and stop of the drive motor 614 and the start and stop of the air pump 69 and the amount of gas injected according to actual needs, realizing the automated and intelligent control of the floating bed operation without frequent manual intervention.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
