Description

Technical Field

[0001] This invention belongs to the field of marine aquaculture wastewater treatment, and specifically relates to wastewater treatment equipment and methods based on marine aquaculture. Background Technology

[0002] The pollution characteristics of aquaculture wastewater are irregular discharge, concentrated drainage period, and large drainage volume. The main pollutants in the wastewater are COD, nitrogen, phosphorus, and SS. The pollutant concentration is low and it is not a point source discharge. The characteristics and concentration of pollutants are closely related to aquaculture mode, species, and density. In order to protect the environment within the aquaculture area, it is necessary to use appropriate wastewater treatment equipment to treat aquaculture wastewater.

[0003] For example, application number "CN202310271898.5" discloses a device and method for treating wastewater from marine aquaculture. This invention provides a wastewater treatment device and method based on marine aquaculture. The wastewater treatment device includes a marine aquaculture pond and a purification tank. A first partition, a second partition, and a third partition are sequentially arranged within the purification tank along the wastewater flow direction. These partitions divide the interior of the purification tank into a sedimentation zone, a filtration zone, an aerobic zone, and an anaerobic zone. The sedimentation zone is connected to the outlet of the marine aquaculture pond, and the outlet of the anaerobic zone is connected to the marine aquaculture pond via a return water pipe to circulate the purified wastewater back to the pond. This invention integrates multiple processes such as sedimentation, filtration, aerobic purification, and anaerobic purification to purify the wastewater discharged from the marine aquaculture pond. The equipment is simple, has good purification effect, and strong stability.

[0004] While it can be used to treat wastewater in sections through multiple partitions, when treating wastewater using the ditch treatment method, the purification agent needs to be put into the ditch to achieve purification. However, because the ditch is long, the area that can be covered by simply throwing the purification agent manually is small, making it impossible to carry out large-scale operations. This leads to low efficiency in treating wastewater.

[0005] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this invention was created. It is hereby provided as a wastewater treatment device and method based on marine aquaculture, which is used to solve the problem that the existing ditch treatment method requires the addition of purification drugs into the ditch to achieve purification. However, due to the long length of the ditch, the area that can be covered by simply manually sprinkling the purification drugs is small, which makes it impossible to achieve large-scale operation and thus leads to low wastewater treatment efficiency. Summary of the Invention

[0006] This invention proposes a wastewater treatment device and method based on marine aquaculture, which solves the problem in the prior art where purification drugs need to be put into the inside of the ditch to achieve purification. However, due to the long length of the ditch, the area that can be covered by simply manually throwing the purification drugs is small, making it impossible to carry out large-scale operations, which leads to low wastewater treatment efficiency.

[0010] In a preferred embodiment, a discharge pipe is fixedly connected to the inner side of the rotating shaft, and the main body of the discharge pipe is a one-way opening structure on the left side. A through hole is opened on the top surface of the discharge pipe, and an injection pipe is fixedly connected inside the through hole. The injection pipe is connected to a flexible hose fixedly connected to the bottom surface of the hopper. The main body of the injection pipe is a two-way through structure on both the upper and lower sides. The injection pipe communicates with the discharge pipe. A side plate is fixedly connected to the inner wall of the discharge pipe, and the main body of the side plate is arranged longitudinally. There are two side plates.

[0011] In a preferred embodiment, a motor is installed on the front end face of the side plate located on the front side, and an output shaft is provided on the rear side of the motor. A throwing wheel is installed on the output shaft, and the throwing wheel is rotatably connected to the inner side of the two side plates. The throwing wheel is located directly below the injection pipe and is used to throw out materials. A feeding wheel is installed on the left opening of the discharge pipe, and there are two feeding wheels in total. The two feeding wheels are installed in a linear array on the front and rear sides inside the discharge pipe.

[0012] In a preferred embodiment, each of the feeding wheels is coaxially mounted with a meshing gear at its top end, and the meshing gear and the feeding wheel together form a transmission structure. One of the feeding wheels is also coaxially mounted with a stepping gear at its bottom end, and a connecting block is fixedly connected to the bottom end of the outer circumference of the discharge pipe. The connecting block has a structure that protrudes from the discharge pipe, and a water pipe is fixedly connected to the bottom end of the connecting block.

[0013] In a preferred embodiment, the water pipe is used for drainage, and a flange is fixedly connected to the rear side of the water pipe. The main body of the flange is a ring structure, and the diameter of the flange is larger than the diameter of the water pipe and is in communication with the water pipe. The flange has through holes arranged in a ring array inside, which are mounting holes. The mounting holes and the flange together form a connection structure.

[0014] In a preferred embodiment, an impeller is installed inside the water pipe, and the impeller is rotatably connected to the inner side of the water pipe via a shaft. An output gear is installed on the top surface of the impeller, and the output gear meshes with a stepping gear located at the bottom of the feeding wheel. The diameter of the output gear is larger than the diameter of the stepping gear.

[0015] This invention discloses a method for using a wastewater treatment device based on seawater aquaculture, comprising the following steps: 1) During the marine aquaculture process, corresponding ditches are usually dug inside the aquaculture area to collect and discharge wastewater in a unified manner. When the ditch is needed to treat the tailwater, the two supports set in the extension frame can be pulled outwards, and the inclined surface of the support away from the extension frame can be brought close to the inner edge of the ditch. Then, the nuts are screwed onto the limiting rod fixed to the outside of the slider to abut against the outer wall of the extension frame, and the base and extension frame are fixed and limited at the same time. 2) Then, after the fixed limit is completed, the sewage pipe to be treated is connected to the flange fixedly connected to the outside of the water pipe, and the sewage is supplied into the inside of the water pipe at the same time. The wastewater purification agent is put into the inside of the hopper fixedly connected to the connecting frame at the same time. After the water enters the inside of the water pipe, the impeller set in the water pipe can be rotated and driven. 3) Then, when the impeller rotates, the output gear set at the top of the impeller can be driven to rotate synchronously. When the output gear rotates, the stepping gear set at the bottom end face of the feeding wheel can be driven to rotate synchronously. When a single feeding wheel set in the discharge pipe rotates, it can be driven to rotate by the meshing gear set at the top of the feeding wheel. When a single meshing gear rotates, the rotation of the two feeding wheels can be used to achieve efficient material throwing by the meshing of the two meshing gears. 4) Then, when there is purification medicine inside the hopper, the hose set on the bottom end of the hopper can be used to enter the inside of the injection pipe fixedly connected to the top end of the discharge pipe. When the material enters the inside of the injection pipe, it can simultaneously enter the inside of the discharge pipe. At this time, the motor installed on the outside of the side plate is started to drive the throwing wheel to rotate, so as to efficiently throw out the material put in through the injection pipe. Through the linkage with the feeding wheel, the automated conveying operation of the purification medicine can be realized. 5) Then, when in use, the discharge pipe is normally tilted upwards for discharging. As the amount of medicine in the discharge hopper decreases, the weight of the hopper decreases. The moving block is pushed by a spring rod in the support frame. When the moving block moves upwards, the meshing of the rack fixed to the outer surface of the moving block and the driven gear on the outer side of the rotating shaft drives the discharge pipe on the inner side of the two rotating shafts to gradually swing downwards. This allows the discharge pipe, which is normally tilted, to slowly descend and perform downward-angle feeding, thus achieving adaptive adjustment.

[0016] After adopting the above technical solution, the beneficial effects of the present invention are: 1. In this invention, an impeller is rotatably connected to a water pipe. When water enters the water pipe and is discharged into the ditch, the impeller in the water pipe rotates synchronously. When the impeller rotates, it also drives the output gear installed at its top to rotate synchronously. When the output gear rotates, it meshes with the stepping gear at the bottom of the feeding wheel. The synchronous counter-rotation of the two feeding wheels achieves automated and efficient conveying of the purified medicine entering through the discharge pipe. This design, through the linkage of the impeller and the feeding wheel, enables automated conveying of medicine, reduces manual labor intensity, and improves the efficiency of wastewater treatment.

[0017] 2. In this invention, by setting a gear fixedly connected to the outside of the moving block, under normal conditions, the material can be thrown to a farther distance for rapid purification by using the upward angle of the discharge pipe. When the material in the hopper decreases, the meshing transmission between the rack and the driven gear fixedly connected to the outside of the rotating shaft can be used to drive the discharge pipe set in the two support frames to adjust the downward angle. This allows for further purification of the water body by changing the projection distance when the purification drug is less, thus achieving a more practical purpose. Attached Figure Description

[0026] This invention discloses a method for using a wastewater treatment device based on seawater aquaculture, comprising the following steps: 1) During the marine aquaculture process, corresponding ditches are usually dug inside the aquaculture area to collect and discharge wastewater in a unified manner. When the ditch is needed to treat the current tailwater, the two supports 3 set in the extension frame 2 can be pulled out to the outside, and the inclined surface of the support 3 away from the extension frame 2 can be brought close to the inner edge of the ditch. At this time, the nut 6 is screwed onto the limiting rod 5 fixedly connected to the outside of the slider 4 to abut against the outer wall of the extension frame 2, and the base 1 and the extension frame 2 can be fixed and limited at the same time. 2) Then, after the fixed limit is completed, the sewage pipe to be treated is connected to the flange 19 fixedly connected to the outside of the water pipe 18, and the sewage is supplied into the inside of the water pipe 18 at the same time. The wastewater purification agent is put into the inside of the hopper 26 fixedly connected to the connecting frame 25 at the same time. When the water enters the inside of the water pipe 18, the impeller 21 set in the water pipe 18 can be rotated and driven. 3) Then, when the impeller 21 rotates, the output gear 22 set at the top of the impeller 21 can be driven to rotate synchronously. When the output gear 22 rotates, the stepping gear 16 set at the bottom end face of the feeding wheel 14 can be driven to mesh synchronously. When a single feeding wheel 14 set in the discharge pipe 10 rotates, the meshing gear 15 set at the top of the feeding wheel 14 can be used to rotate. When a single meshing gear 15 rotates, the rotation of the two feeding wheels 14 can be used to achieve efficient material throwing operation by meshing the two meshing gears 15. 4) Then, when there is purification medicine inside the hopper 26, the hose 27 set on the bottom surface of the hopper 26 can be used to enter the inside of the injection pipe 28 fixedly connected to the top surface of the discharge pipe 10. When the material enters the injection pipe 28, it can simultaneously enter the inside of the discharge pipe 10. At this time, the motor 12 installed on the outside of the side plate 11 is started to drive the throwing wheel 13 to rotate, so as to efficiently throw out the material put in through the injection pipe 28. And through the linkage with the feeding wheel 14, the automated conveying operation of the purification medicine can be realized. 5) Then, when in use, the discharge pipe 10 is normally tilted upwards for discharging. As the amount of medicine in the discharge hopper 26 decreases, the weight of the hopper 26 decreases. The moving block 23 is pushed by the spring rod 24 in the support frame 7. When the moving block 23 moves upwards, the rack 29 fixedly connected to the outer surface of the moving block 23 and the driven gear 9 on the outer side of the rotating shaft 8 are meshed to drive the discharge pipe 10 on the inner side of the two rotating shafts 8 to swing downwards gradually. This allows the discharge pipe 10, which is normally tilted, to slowly descend and perform downward angle feeding, thereby achieving adaptive adjustment.

[0027] In use, during the marine aquaculture process, corresponding ditches are usually dug inside the aquaculture area to collect and discharge wastewater in a unified manner. When the ditch is needed to treat the current tailwater, the two supports 3 set in the extension frame 2 can be pulled out to the outside, and the inclined surface of the support 3 away from the extension frame 2 can be brought close to the inner edge of the ditch. At this time, the nut 6 is screwed onto the limiting rod 5 fixedly connected to the outside of the slider 4 to abut against the outer wall of the extension frame 2, and the base 1 and the extension frame 2 can be fixed and limited at the same time. After the fixed limit is completed, the sewage pipe to be treated is connected to the flange 19 fixedly connected to the outside of the water pipe 18, and the sewage is supplied into the inside of the water pipe 18 at the same time. The wastewater purification agent is put into the inside of the hopper 26 fixedly connected to the connecting frame 25 at the same time. After the water enters the inside of the water pipe 18, the impeller 21 set in the water pipe 18 can be rotated and driven. Furthermore, when the impeller 21 rotates, the output gear 22 located at the top of the impeller 21 can be driven to rotate synchronously. When the output gear 22 rotates, the stepping gear 16 located on the bottom surface of the feeding wheel 14 can be driven to rotate synchronously. When a single feeding wheel 14 located in the discharge pipe 10 rotates, it can be driven to rotate by the meshing gear 15 located at the top of the feeding wheel 14. When a single meshing gear 15 rotates, the rotation of the two feeding wheels 14 can be achieved by meshing the two meshing gears 15 together to achieve efficient material throwing. Furthermore, when there is purification medicine inside the hopper 26, it can be accessed through the flexible hose 27 set on the bottom surface of the hopper 26 to the inside of the injection pipe 28 fixedly connected to the top surface of the discharge pipe 10. When the material enters the injection pipe 28, it can simultaneously enter the inside of the discharge pipe 10. At this time, the motor 12 installed on the outside of the side plate 11 is started to drive the throwing wheel 13 to rotate, so as to efficiently throw out the material put in through the injection pipe 28. And through the linkage with the feeding wheel 14, the automated conveying operation of the purification medicine can be realized. Furthermore, when in use, the discharge pipe 10 is normally tilted upwards for discharging. As the amount of medicine in the discharge hopper 26 decreases, the weight of the hopper 26 decreases. The moving block 23 is pushed by the spring rod 24 set in the support frame 7. When the moving block 23 moves upwards, the meshing of the rack 29 fixed to the outer surface of the moving block 23 and the driven gear 9 set on the outer side of the rotating shaft 8 drives the discharge pipe 10 set on the inner side of the two rotating shafts 8 to gradually swing downwards. This allows the discharge pipe 10, which is normally tilted, to slowly descend and change to a downward angle for discharging, thereby achieving adaptive adjustment.
