Description

Technical Field

[0001] The present invention relates to the technical field of underwater sludge treatment, and particularly to a device for underwater sludge treatment. Background Art

[0002] With the progress of fish farming technology, especially the popularization of high-density farming methods, organic matters in fish ponds such as excreta of cultured organisms, artificially fed baits, residues generated by fertilization, and corpses of organisms in the water body, etc., are often difficult to be fully decomposed due to the water depth limitation. Most of them eventually sink to the bottom, mix with sediment, and gradually accumulate into sludge, covering the original bottom soil of the fish pond. The composition of the sludge is complex, mainly including surface organisms, clay, humus, nitrogen-containing compounds, inorganic salts, and carbohydrates, etc.

[0003] The sludge plays a crucial role in the bottom quality of fish ponds. It can not only provide necessary fertilizers, maintain water quality stability, but also regulate water quality to a certain extent. Appropriate thickness of sludge (usually 15 - 20 cm) is crucial for the growth of fish and the sustainable development of aquaculture, because it can play the roles of fertilizer retention, fertilizer supply, and water quality buffering. However, too thick sludge will weaken these beneficial effects and may bring adverse effects to aquaculture, such as reducing fish production, causing hypoxia, triggering fish diseases, and deteriorating water quality. The nutrients rich in the sludge provide an ideal growth environment for microorganisms and crustaceans, thus providing an additional bait source for fish. In addition, the colloidal substances in the sludge can absorb and temporarily fix a part of organic matters and inorganic salts, and gradually release them into the water for phytoplankton to use at an appropriate time. At the same time, the bacteria in the sludge reduce the deposition of organic matters by decomposition, which helps to maintain good water quality. These bacteria continuously release nutrients such as nitrogen, phosphorus, and potassium into the water body through decomposition, providing nutrients for phytoplankton, etc., thereby promoting the overall improvement of aquaculture production.

[0004] However, excessive accumulation of sludge will have an adverse impact on fish ponds, such as reducing the living space of fish, causing hypoxia, and increasing the reproduction of pathogens and parasites, thus affecting the growth and production of fish. When there is too much sludge in the pond, the content of organic matters in the water will also increase accordingly. These organic matters are oxidized and decomposed by bacteria, consuming a large amount of oxygen in the water, and then triggering the phenomenon of water body hypoxia. In an anoxic environment, reducing intermediate products such as carbon monoxide, carbon dioxide, hydrogen, organic acids, lower amines, and sulfuric acid will be produced. The continuous accumulation of these harmful substances in the water not only interferes with the normal growth and development of fish, but also seriously leads to fish floating head, pond flooding, and even death.

[0005] In addition, excessive accumulation of silt will also cause the content of organic substances in the water to increase. During the oxidation and decomposition of these organic substances, a large amount of oxygen in the water will be consumed, which will prompt the rapid and massive reproduction of anaerobic bacteria, producing reducing intermediate products such as methane. The continuous accumulation of these substances in the water poses a direct threat to the growth of cultured organisms and may lead to a decrease in production. In the high-temperature season, a sudden change in weather causes the surface water temperature of the pond to drop rapidly, which will lead to water convection and the exchange of upper and lower water layers, making the fish pond fall into a state of extreme oxygen deficiency. As a result, fish may show floating heads and even suffocate due to lack of oxygen. At the same time, it will also increase the risk of explosive fish diseases. In addition, too much silt is likely to deteriorate the water quality and increase the acidity, which will then lead to the massive reproduction of germs. In a bad environment, fish may suffer from chronic poisoning by harmful substances, such as paralysis and asphyxiation, and the resistance of the fish body will decline, making it more likely to cause fish diseases. At the same time, the parasites, bacteria and viruses existing in the silt also pose a threat to fish.

[0006] In addition to pumping water to expose and disinfect the silt, the silt can also be treated by adding drugs. The drugs for treatment include quicklime, bleaching powder, sodium dichloroisocyanurate powder, etc.

[0007] The existing drug addition is mostly to sprinkle the drugs into the water area by a drug addition boat. Since this drug addition method relies on manual operation, it leads to uneven sprinkling and easy leakage. At the same time, it requires continuous manual monitoring, and dust is easily generated during the sprinkling process, posing a health risk to the operators. Therefore, the overall operation process is rather cumbersome.

[0008] Therefore, the present invention proposes a device for underwater sludge treatment, which is used to improve the convenience of drug addition during underwater sludge treatment. Summary of the Invention

[0010] To achieve the above purpose and other related purposes, the present invention provides a device for underwater sludge treatment, including a material storage mechanism. An extending mechanism extending outward is arranged on the outer surface of the material storage mechanism, and a buoyancy support mechanism is arranged at the end of the extending mechanism;

[0011] A driving mechanism is arranged above the material storage mechanism. The driving mechanism penetrates from the inside of the material storage mechanism to the bottom of the material storage mechanism. A throwing mechanism is arranged at the lower end of the driving mechanism. The throwing mechanism can be driven by the driving mechanism to rotate. The drugs stored inside the material storage mechanism can fall from the material storage mechanism to the top of the throwing mechanism and be thrown into the water by the rotating throwing mechanism;

[0012] Meanwhile, the driving force generated by the driving mechanism will stir and push the medicine inside the material storage mechanism;

[0013] An air pump is provided at the top of the driving mechanism. The air pump is connected to the buoyancy support mechanism through a pipeline, and the air pump can control the buoyancy of the buoyancy support mechanism, so that the bottom of the throwing mechanism is in or out of the water, and the throwing range of the medicine can be changed by changing the height of the throwing mechanism.

[0014] Preferably, the material storage mechanism includes a material storage container. A bearing seat is provided at the center of the bottom of the material storage container. A plurality of equally spaced connectors are provided on the outer surface of the bearing seat, and an extension mechanism is connected to each connector;

[0015] A material discharge port is provided at the bottom of the material storage container;

[0016] A support frame is provided at the top of the material storage container. A flange plate is provided at the upper end of the support frame, and the driving mechanism is installed and supported on the flange plate.

[0017] Preferably, the extension mechanism includes an extension rod. One end of the extension rod is connected to the connector, and a connecting ring is provided at the other end of the extension rod;

[0018] The buoyancy support mechanism is installed in the connecting ring in a separable manner.

[0019] Preferably, the buoyancy support mechanism includes an air flotation airbag. A support pipe is provided at the upper end of the air flotation airbag. A connecting flange head is provided at the upper end of the support pipe. The connecting flange head penetrates through the center of the connecting ring. A sealing cover is provided at the end of the connecting flange head. The sealing cover is detachably connected to the connecting flange head, and the sealing cover and the air pump are connected through a pipeline.

[0020] Preferably, the driving mechanism includes a driving motor. The driving motor is vertically installed at the top of the flange plate. A driving rod is provided on the output shaft of the driving motor. The lower end of the driving rod penetrates through the center of the bearing seat and extends to the bottom of the material storage container. The throwing mechanism is installed at the lower end of the driving rod.

[0021] Preferably, stirring blades are provided on the outer surface of the driving rod, and the stirring blades are located inside the material storage container.

[0022] Preferably, both the driving motor and the air pump are provided with wireless communication control modules, and both the driving motor and the air pump can be powered by wired or wireless means.

[0023] Preferably, the throwing mechanism includes a throwing disc. The center of the top of the throwing disc is connected to the lower end of the driving rod, and a plurality of material extraction ribs are arranged in a circumferential array on the top of the throwing disc.

[0024] Preferably, each of the material-drawing ribs is an S-shaped rib.

[0025] Preferably, a plurality of oxygen-increasing sheets arranged in a circumferential array are provided at the bottom of the material-throwing disc, and a plurality of bubble holes are provided on each oxygen-increasing sheet;

[0026] Adjusting the buoyancy of the buoyancy support mechanism can make the oxygen-increasing sheet in or out of the water.

[0027] As described above, a device for underwater sludge treatment of the present invention has the following beneficial effects:

[0028] 1. By setting the buoyancy support mechanism, the material storage mechanism floats on the water surface, and a driving mechanism is provided on the material storage mechanism to drive the rotation of the material-throwing mechanism located at the bottom of the material storage mechanism. By the rotation of the material-throwing mechanism, the drug falling from the material storage mechanism is whipped, so that the drug can be evenly scattered around with the material storage mechanism as the axis, improving the uniformity and convenience of drug scattering.

[0029] At the same time, the driving mechanism is controlled by remote control, so that remote control of drug throwing can be realized, without the need for operators to approach, avoiding harm to operators caused by drug powder.

[0030] 2. By setting an air pump on the top of the driving motor and charging and discharging air into and out of the air-floating airbag by the air pump to change the buoyancy of the air-floating airbag, the oxygen-increasing sheet at the bottom of the material-throwing disc can be in or out of the water. When throwing drugs, the oxygen-increasing sheet is out of the water to reduce the resistance when the material-throwing disc rotates, improving the working efficiency of the driving motor when throwing drugs. When not throwing drugs, the oxygen-increasing sheet can be placed in the water, and the oxygen-increasing sheet stirs in the water to generate bubbles, increasing the contact area between the water surface and the air, accelerating the rate of oxygen dissolved in the water, and promoting the uniform distribution of oxygen throughout the water area, avoiding local hypoxia, and achieving the effect of increasing the oxygen content in the water.

[0031] 3. By setting stirring blades on the outer surface of the driving rod and making the stirring blades located inside the material storage container, when throwing drugs, the stirring blades will rotate with the rotation of the driving rod, thereby stirring the drugs in the material storage container and breaking up the caked drugs under the action of high-speed rotation. This design further enhances the uniformity of drug scattering.

[0032] At the same time, when placing breeding feed in the material storage container, the feed can be scattered by the rotation of the material-throwing disc, which further assists farmers, expands the application range of the device, and effectively avoids the idle of the device.

[0033] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand the other advantages and effects of the present invention from the content disclosed in this specification.

[0051] Please refer to Figures 1 to 9 . It should be noted that the structures, proportions, sizes, etc. shown in the drawings of this specification are only used to match the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the conditions for the implementation of the present invention. Therefore, they do not have substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size, without affecting the efficacy that the present invention can produce and the purpose that can be achieved, should still fall within the scope covered by the technical content disclosed in the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle", and "one" cited in this specification are only for the convenience of clear narration and are not used to limit the scope for the implementation of the present invention. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope for the implementation of the present invention.

[0052] As Figures 1 - 4 shown, the present invention provides a device for underwater sludge treatment, including a material storage mechanism 1, and the inside of the material storage mechanism 1 can store drugs for sludge treatment in batches. An extending mechanism 2 extending outward is arranged on the outer surface of the material storage mechanism 1, and a buoyancy support mechanism 3 is arranged at the end of the extending mechanism 2. The material storage mechanism 1 floats on the water surface due to the buoyancy provided by the buoyancy support mechanism 3.

[0053] A driving mechanism 4 is arranged above the material storage mechanism 1, and the driving mechanism 4 penetrates from the inside of the material storage mechanism 1 to the bottom of the material storage mechanism 1. The lower part of the driving mechanism 4 is connected to a material throwing mechanism 6, and the material throwing mechanism 6 realizes a rotating motion under the drive of the driving mechanism 4. The drugs stored in the material storage mechanism 1 can smoothly slide to the top of the material throwing mechanism 6 and are then evenly scattered into the water by the rotating material throwing mechanism 6. Thus, the drugs are evenly scattered and diffused in a circular shape with the material throwing mechanism 6 as the axis, improving the uniformity of drug scattering. At the same time, several such devices for underwater sludge treatment are arranged at intervals of the scattering radius of the material throwing mechanism 6 on the water area to cover the water area, thereby avoiding the situation of leakage. In order to improve the convenience of control, a remote sensing module is arranged on both the driving motor 41 and the air pump 5, so that the start and stop of the driving motor 41 and the air pump 5 can be controlled respectively through a remote control device.

[0054] At the same time, the driving force generated by the driving mechanism will stir and push the drugs inside the material storage mechanism, so that the drugs can be evenly stirred and the caked drugs can be broken, further improving the effect of the drugs.

[0055] At the top of the driving mechanism 4, an air pump 5 is provided. The air pump 5 is connected to the buoyancy support mechanism 3 through a pipeline, and the air pump 5 can control the buoyancy of the buoyancy support mechanism 3, so that the bottom of the material throwing mechanism 6 is in or out of the water. When the material throwing mechanism 6 is out of the water, the resistance during rotation of the material throwing mechanism 6 can be reduced. When the material throwing mechanism 6 is in the water, the rotating material throwing mechanism 6 can stir the water body to generate bubbles and eliminate the stratification phenomenon of the water body, increase the oxygen content of the water body and make the oxygen in the water body evenly distributed. It can effectively avoid the hypoxia of organisms in the water body. And the range of drug spraying can be changed by changing the height of the material throwing mechanism 6. When the material throwing mechanism 6 is at a high position, the range of drug spraying increases. When the height of the material throwing mechanism 6 is reduced, the spraying range will decrease accordingly.

[0056] As Figure 5 and Figure 6 shown, in some embodiments, the storage mechanism 1 of the present invention includes a storage container 11. A bearing seat 12 is provided at the axis of the bottom of the storage container 11. A bearing is provided inside the bearing seat 12, and the bearing is sleeved on the outer surface of the driving rod 42 to reduce the friction when the driving rod 42 rotates. An oil seal is provided on the bearing inside the bearing seat 12 to increase the sealing performance. A plurality of equally spaced connecting heads 13 are provided on the outer surface of the bearing seat 12, preferably distributed in a triangular shape. Each connecting head 13 is connected with an extension mechanism 2, and a plurality of buoyancy support mechanisms 3 are connected through the plurality of extension mechanisms 2 to improve the floating stability of the device on the water surface.

[0057] A material discharging port 14 is provided at the bottom of the storage container 11. The drug in the storage container 11 falls from the material discharging port 14 to the top of the material throwing mechanism 6 under the action of gravity, and the drug is scattered by the rotation of the material throwing mechanism 6. A butterfly valve can be provided at the opening of the material discharging port 14, so that the amount of drug discharged from the material discharging port 14 can be controlled.

[0058] A support frame 15 is provided at the top of the storage container 11, and a flange plate 16 is provided at the upper end of the support frame 15. The driving motor 41 is installed and supported on the flange plate 16. Thus, the driving motor 41 is located at the top of the axis of the storage container 11, avoiding the driving motor 41 from hindering the addition of drugs in the storage container 11 and avoiding the driving motor 41 from reducing the volume in the storage container 11. As Figure 2 shown, in some embodiments, the extension mechanism 2 of the present invention includes an extension rod 21. The length of the extension rod 21 is much larger than the diameter of the storage container 11. One end of the extension rod 21 is connected to the connecting head 13, and the connection part is detachable. The other end of the extension rod 21 is provided with a connection ring 22, and the connection ring 22 is a circular ring. The buoyancy support mechanism 3 is installed in the connection ring 22 in a separable manner, so that the buoyancy support mechanism 3 can be disassembled and assembled according to requirements.

[0059] As Figure 7As shown, in some embodiments, the buoyancy support mechanism 3 of the present invention includes an air flotation airbag 31. The air flotation airbag 31 is expandable and contractible. When inflated, its volume increases, enhancing buoyancy; when deflated, its volume decreases, reducing buoyancy, so as to adjust the height of the entire device in water. The upper end of the air flotation airbag 31 is provided with a support pipe 32. The support pipe 32 is a rigid pipe, which is used to enhance the connection strength between the air flotation airbag 31 and the connection ring 22 and increase the distance between the air flotation airbag 31 and the connection ring 22. The upper end of the support pipe 32 is provided with a connection flange head 33. The connection flange head 33 penetrates through the axis of the connection ring 22. The end of the connection flange head 33 is provided with a sealing cover 34. The sealing cover 34 is threadedly connected to the connection flange head 33 to form a clamping force to clamp the upper and lower ends of the connection ring 22, fixing the air flotation airbag 31 on the connection ring 22. The connection between the connection flange head 33 and the sealing cover 34 is sealed to prevent air leakage. The sealing cover 34 is connected to the air pump 5 through a pipeline. When the air pump 5 inflates the inside of the air flotation airbag 31 through the pipeline, the volume of the air flotation airbag 31 will increase, thereby increasing buoyancy. When it is necessary to reduce the buoyancy of the air flotation airbag 31, the air in the air flotation airbag 31 can be pumped out through the air pump 5 to reduce the volume of the air flotation airbag 31.

[0060] As Figure 8 shown, in some embodiments, the drive mechanism 4 of the present invention includes a drive motor 41. The drive motor 41 is a motor with a PLC module, enabling the drive of the drive motor 41 to be precisely controlled. The drive motor 41 is vertically installed on the top of the flange plate 16. And the drive motor 41 is located at the axis of the storage vessel 11, thus ensuring the centrality of the axis of the entire device. A drive rod 42 is provided on the output shaft of the drive motor 41. The lower end of the drive rod 42 penetrates through the axis of the bearing seat 12 and extends to the bottom of the storage vessel 11. The material throwing mechanism 6 is installed at the lower end of the drive rod 42. When the drive motor 41 drives the drive rod 42 to rotate, the material throwing mechanism 6 installed at the end of the drive rod 42 will rotate accordingly. The rotating material throwing mechanism 6 will throw the medicine falling on the top of the material throwing mechanism 6 into the water under the action of centrifugal force and friction.

[0061] It should be noted that both the drive motor 41 and the air pump 5 are provided with wireless communication control modules, so that the start and stop of the drive motor 41 and the air pump 5 can be controlled separately through a remote sensing device such as a remote control. The drive motor 41 and the air pump 5 can be powered by a wired cable or a wireless battery. The wired cable can tow the entire device to prevent the device from drifting on the water surface. And battery power supply can improve the convenience of device arrangement. When necessary, the two power supply methods can be used in combination.

[0062] As Figure 3 and Figure 8In some embodiments as shown, a stirring blade 43 is provided on the outer surface of the driving rod 42 of the present invention, and the stirring blade 43 is located inside the storage vessel 11. When the driving rod 42 rotates, the stirring blade 43 will rotate accordingly to stir the medicine or feed in the storage vessel 11, improving the uniformity of the medicine or feed. At the same time, the power generated when the stirring blade 43 rotates will break up the caked medicine or feed, thus avoiding caking of the medicine or feed.

[0063] As Figure 8 shown, in some embodiments, the throwing mechanism 6 of the present invention includes a throwing disc 61. The axis at the top of the throwing disc 61 is connected to the lower end of the driving rod 42, and a plurality of material extraction ribs 62 are arranged in a circumferential array on the top of the throwing disc 61. When the throwing disc 61 rotates with the driving rod 42, the material extraction ribs 62 on the top of the throwing disc 61 will beat the medicine or feed falling on the top of the driving motor 41 under the action of the rotational force, so that the medicine or feed is widely scattered into the water under the action of the material extraction ribs 62. Compared with directly scattering the medicine through centrifugal force and frictional force, the scattering range of the medicine can be effectively improved.

[0064] As Figure 8 shown, in some embodiments, each of the material extraction ribs 62 of the present invention is an S-shaped rib. Compared with a straight rib, the S-shaped rib has a larger contact area with the medicine. And when the material extraction rib 62 beats the medicine, the force direction of the medicine can be in an arc shape, which has a larger diffusion range and better uniformity compared with the linear force of the straight rib.

[0065] As Figure 9 shown, in some embodiments, a plurality of oxygenation sheets 63 arranged in a circumferential array are provided at the bottom of the throwing disc 61 of the present invention. Adjusting the buoyancy of the buoyancy support mechanism 3 can make the oxygenation sheets 63 be in or out of the water. When the oxygenation sheets 63 rotate in the water, the oxygenation sheets 63 will stir the water body, so that water bubbles are generated in the water body to increase the contact area between the water surface and the air. At the same time, the stratification phenomenon of the water body is eliminated, and the oxygen in the water body is evenly distributed. A plurality of bubble holes 64 are provided on each oxygenation sheet 63. When the oxygenation sheets 63 stir the water body, the bubble holes 64 will further divide the water body, so that more water bubbles are generated in the water and the stratification phenomenon of the water body is better eliminated.

[0066] The specific use process of the present invention is as follows:

[0067] Taking quicklime as the medicament to treat underwater sludge as an example:

[0068] Sludge treatment:

[0069] All the devices are arranged equidistantly on the water area, and quicklime is placed inside the storage vessel 11;

[0070] Remotely start the drive motor 41 to make the material throwing disc 61 rotate driven by the drive motor 41. Use the material pumping ribs 62 to whip the quicklime falling from the storage vessel 11, so that the quicklime falls into the water. The quicklime gradually precipitates to the bottom and contacts the sludge. During this process, the quicklime reacts chemically with water to produce calcium hydroxide, which rapidly raises the pH value of the pool water above 11. At the same time, a large amount of heat energy is released, quickly killing wild fish, various eggs, aquatic insects, snails, moss, parasites, pathogens, etc.

[0071] When using the wet method for pond cleaning, the dosage of quicklime per mu is 125 kg - 150 kg, and it can be increased or decreased by 10% according to the sludge thickness.

[0072] Feed feeding:

[0073] Place the feed in the storage vessel 11, and drive the material throwing disc 61 to rotate by the drive motor 41. Use the material pumping ribs 62 on the material throwing disc 61 to whip the feed, so that the feed is evenly put into the water to feed the organisms in the water.

[0074] Water body oxygenation:

[0075] Use the air pump 5 to pump out the air in the air flotation airbag 31, reduce the overall buoyancy, and ensure that the oxygenation tablets 63 are immersed in the water.

[0076] Drive the material throwing disc 61 to rotate by the drive motor 41, so that the oxygenation tablets 63 stir the water body, increase the contact area between the water body and the air, eliminate the stratification of the water body, improve the oxygen content in the water body and the uniformity of oxygen.

[0077] In summary, for the device for underwater sludge treatment of the present invention, by setting the buoyancy support mechanism 3, the storage mechanism 1 floats on the water surface, and a drive mechanism 4 is arranged on the storage mechanism 1 to drive the material throwing mechanism 6 located at the bottom of the storage mechanism 1 to rotate. By the rotation of the material throwing mechanism 6, the medicine falling from the storage mechanism 1 is whipped, so that the medicine can be evenly scattered around with the storage mechanism 1 as the axis, improving the uniformity of medicine scattering.

[0078] At the same time, control the drive mechanism 4 by means of remote control, so as to realize remote control of medicine throwing, without the need for operators to approach, and avoid harm to the operators caused by medicine powder.

[0079] In the present invention, an air pump 5 is provided on the top of the drive motor 41, and the air pump 5 inflates and deflates the inside of the air flotation airbag 31 to change the buoyancy of the air flotation airbag 31, so that the oxygenation sheet 63 at the bottom of the throwing tray 61 can be in or out of the water. When throwing drugs, the oxygenation sheet 63 is out of the water to reduce the resistance when the throwing tray 61 rotates, improving the working efficiency of the drive motor 41 when throwing drugs. When not throwing drugs, the oxygenation sheet 63 can be placed in the water, and the oxygenation sheet 63 stirs in the water to generate bubbles, increasing the contact area between the water surface and the air, accelerating the rate of oxygen dissolution into the water, and promoting the uniform distribution of oxygen throughout the water area to avoid local oxygen deficiency, achieving the effect of increasing the oxygen content in the water body.

[0080] In the present invention, stirring blades 43 are provided on the outer surface of the drive rod 42, and the stirring blades 43 are located inside the storage container 11. When throwing drugs, the stirring blades 43 will rotate with the rotation of the drive rod 42, thereby stirring the drugs in the storage container 11 and breaking up the agglomerated drugs under the action of high-speed rotation, which further ensures the uniformity of drug throwing.

[0081] Meanwhile, when placing breeding feed in the storage container 11, the feed can be thrown by the rotation of the throwing tray 61, further assisting the farmers, broadening the application range of the device, effectively avoiding the idle state of the device, and improving the usage efficiency.

[0082] Therefore, the present invention effectively overcomes various disadvantages in the prior art and has high industrial utilization value.

[0083] The above embodiments are only illustrative of the principles and effects of the present invention, and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
