Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater treatment device for lake net enclosure aquaculture. Background Technology

[0002] Lake enclosure aquaculture is a method of aquaculture that utilizes lake waters. It plays an important role in the aquaculture industry. Typically, a suitable area in a lake is selected, and a certain area is enclosed using materials such as nets and wooden stakes to create an aquaculture area. Aquatic products (such as fish, shrimp, and crabs) are then released into this area for cultivation. Lake enclosure aquaculture wastewater treatment devices are specifically designed to purify wastewater generated from lake enclosure aquaculture. They aim to solve the environmental pollution problems caused by wastewater discharge, ensure the ecological balance of lakes, and meet the special needs of the enclosure aquaculture scenario.

[0003] However, existing technologies still have the following problems:

[0004] Currently, for the treatment of wastewater from lake enclosure aquaculture, some farmers use simple sedimentation methods, which are inefficient and fail to effectively remove key pollutants such as nitrogen and phosphorus from the wastewater. Although some traditional wastewater treatment equipment can achieve a certain purification effect, it has problems such as large footprint, complex structure, high operating cost, and inconvenient operation and maintenance. Furthermore, it is difficult to discharge wastewater, as the complex pollutants in the wastewater can easily cause blockages during the discharge process, resulting in slow discharge speed and the formation of pollutant clumps. Utility Model Content

[0005] In order to solve the problems of low sewage treatment efficiency and difficulty in sewage discharge, the purpose of this utility model is to provide a sewage treatment device for lake net enclosure aquaculture.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a wastewater treatment device for lake net enclosure aquaculture, comprising a tank body, wherein the tank body is provided with a water distribution tank, a sedimentation tank, an outlet tank, and a sludge tank. An inlet is provided on the side of the tank body near the water distribution tank, and an outlet is provided on the side of the tank body near the outlet tank. A first motor is fixedly installed on the upper surface of the water distribution tank, and a stirring paddle is fixedly connected to the output end of the first motor. An inclined tube assembly is fixedly installed inside the sedimentation tank. The sludge tank is located below the sedimentation tank, and a discharge device is fixedly installed at the lower part of the sludge tank.

[0007] Preferably, the discharge device includes a support housing, the upper end of which is connected through to the bottom end of the sludge bin, and a discharge port is provided on the lower surface of the support housing. Two screws are rotatably connected inside the support housing. A second motor is fixedly installed on one side of the support housing. The output end of the second motor is fixedly connected to one of the screws. A gear is fixedly sleeved on one end of each of the two screws, and the outer surface of one gear meshes with the outer surface of the other gear.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] This invention utilizes a combination of a water distribution tank, a sedimentation tank, a water outlet tank, a stirring paddle, and a discharge device. The first motor and stirring paddle in the water distribution tank, working in conjunction with the feeding pipe, quickly and thoroughly mix the chemicals with the wastewater, accelerating the coagulation process of pollutants. The inclined tubes in the sedimentation tank, arranged in a parallel honeycomb structure, significantly increase the sedimentation area. Based on the principle of "shallow sedimentation," this method significantly improves solid-liquid separation efficiency compared to traditional sedimentation methods. The second motor in the discharge device drives a screw and gears to smoothly squeeze out the sludge settled in the sludge bin, ensuring timely discharge. A water pump draws wastewater from the water distribution tank and sprays it into the sludge bin through nozzles on the second connecting pipe, rinsing and diluting the sludge. This not only reduces the viscosity of the sludge, making it easier to discharge, but also prevents sludge clumping, reducing cleaning difficulty and labor maintenance costs.

[0015] 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.

[0016] Example: Figs. 1-3 As shown, this utility model provides a device including a silo body 11. The silo body 11 has a water distribution tank 12, a sedimentation tank 13, an outlet tank 14, and a sludge bin 17 respectively. The silo body 11 has an inlet 10 on the side near the water distribution tank 12 and an outlet 22 on the side near the outlet tank 14. A motor bracket 18 is fixedly installed on the upper surface of the water distribution tank 12. A first motor 19 is fixedly installed on the upper surface of the motor bracket 18. An agitator 20 is fixedly connected to the output end of the first motor 19. An inclined tube assembly 16 is fixedly installed inside the sedimentation tank 13. The sludge bin 17 is located below the sedimentation tank 13. A discharge device 24 is fixedly installed at the lower part of the sludge bin 17.

[0017] A water pump 32 is fixedly installed on one side of the silo 11. The input end of the water pump 32 is fixedly connected to a first connecting pipe 33. One end of the first connecting pipe 33 is connected to the water distribution tank 12. Its function is to extract the wastewater that has been initially mixed in the water distribution tank 12. The output end of the water pump 32 is fixedly connected to a second connecting pipe 34. One end of the second connecting pipe 34 passes through the sludge silo 17 and is fixedly connected to the inner wall of the sludge silo 17. Multiple nozzles corresponding to the positions of the screw 26 are fixedly connected to the outer surface of the second connecting pipe 34. These nozzles can spray the wastewater extracted by the water pump 32 into the sludge silo 17 to wash and dilute the sludge. On the one hand, this facilitates the discharge of the sludge through the discharge device 24. On the other hand, it can prevent the sludge from clumping in the sludge silo 17, thus realizing the auxiliary function of sludge treatment in the sludge silo 17.

[0018] A motor bracket 18 is fixedly installed on the upper surface of the water distribution tank 12. The upper surface of the motor bracket 18 is fixedly connected to the first motor 19. A partition 21 is fixedly installed inside the water distribution tank 12. Multiple perforations are opened on the outer surface of the partition 21. Its function is to perform preliminary filtration of the sewage entering the water distribution tank 12 and slow down the water flow speed so that the sewage can flow into the sedimentation tank 13 more evenly and stably. A through groove connected to the sedimentation tank 13 is opened on one side of the water distribution tank 12 to facilitate the flow of sewage from the water distribution tank 12 into the sedimentation tank 13. Two feed pipes are fixedly inserted on the other side of the water distribution tank 12 for adding the agents required for sewage treatment into the water distribution tank 12. Together with the first motor 19 and the stirring paddle 20, the sewage is treated by adding chemicals and stirring.

[0019] Inclined tube supports 15 are fixedly installed between the inner walls of the sedimentation tank 13. Inclined tube groups 16 are located inside the inclined tube supports 15. The inclined tube groups 16 are arranged in parallel and in a honeycomb pattern. This structural design greatly increases the sedimentation area and improves the sedimentation efficiency of solid particles in sewage by utilizing the principle of "shallow sedimentation". This allows for efficient solid-liquid separation of sewage in the sedimentation tank 13. A water collection tank 30 is fixedly connected to one side of the sedimentation tank 13. A water outlet 31 is opened on one side of the water collection tank 30 and communicates with the water outlet tank 14. After sedimentation treatment, the sewage flows into the water outlet tank 14 through the water outlet 31.

[0020] Multiple cotton slubs 23 are fixedly installed inside the effluent tank 14. The function of the cotton slubs 23 is to deeply filter and adsorb the sewage after sedimentation treatment, further removing residual fine impurities, some organic matter, and odors in the water, thereby improving the purification level of the sewage and ensuring that the water discharged from the effluent outlet 22 meets a higher standard.

[0021] The discharge device 24 includes a support housing 25, the upper end of which is connected to the bottom end of the sludge bin 17. A discharge port 29 is provided on the lower surface of the support housing 25. Two screws 26 are rotatably connected inside the support housing 25. The surfaces of the screws 26 are coated with polytetrafluoroethylene (PTFE) to reduce the adhesion between the sludge and the blades. A second motor 27 is fixedly installed on one side of the support housing 25. The output end of the second motor 27 is fixedly connected to one of the screws 26. Gears 28 are fixedly fitted to one end of each screw 26, with the outer surface of one gear 28 meshing with the outer surface of the other gear 28. The second motor 27 drives the screws 26 to rotate, and through the meshing transmission of the gears 28, the two screws 26 rotate synchronously, squeezing the sludge deposited in the sludge bin 17 out of the discharge port 29, thus achieving the sludge discharge function, ensuring the normal operation of the sludge bin 17, and preventing excessive sludge accumulation from affecting the overall treatment effect of the wastewater treatment device.

[0022] Working principle: Wastewater enters the distribution tank 12 of the chamber 11 through the inlet 10. The first motor 19 on the upper surface of the distribution tank 12 drives the stirring paddle 20 to rotate, stirring the wastewater. At the same time, treatment agents are added into the distribution tank 12 through the feed pipe, so that the pollutants in the wastewater are fully mixed and reacted with the agents. The baffle 21 inside the distribution tank 12 has multiple perforations, so that the wastewater is evenly distributed inside the distribution tank 12. Then it flows into the sedimentation tank 13 through the channel, which plays a role in preliminary filtration and buffering the water flow. The sedimentation tank 13 is equipped with inclined tube support 15 and inclined tube group 16. The inclined tube group 16 is arranged in parallel and honeycomb. This structure can increase the sedimentation area and sedimentation efficiency of impurities in the wastewater, so that the solid particles in the wastewater sink to the bottom of the sedimentation tank 13 under the action of gravity, and then flow into the outlet tank 14 through the outlet hole 31 on the collection tank 30.

[0023] The sludge at the bottom of the sedimentation tank 13 will gradually accumulate into the sludge bin 17, and the discharge device 24 at the bottom of the sludge bin 17 is used to discharge the sludge. There are two screws 26 rotatably connected inside the support housing 25 of the discharge device 24. A second motor 27 on one side drives one of the screws 26 to rotate. The gears 28 fixedly sleeved at one end of the two screws 26 mesh with each other, so that the two screws 26 rotate synchronously and squeeze the sludge out from the discharge port 29.

[0024] The water outlet tank 14 is equipped with multiple rattan cotton 23s to further filter and adsorb the water after sedimentation, remove the fine impurities and some organic matter remaining in the water, so that the treated water reaches a high water quality standard, and is finally discharged from the water outlet 22.

[0025] The water pump 32 on one side of the silo 11 draws water from the water distribution tank 12 through the first connecting pipe 33, and then transports the water to the sludge silo 17 through the second connecting pipe 34. The nozzle on the outer surface of the second connecting pipe 34 corresponds to the position of the screw 26. The water sprayed from the nozzle can wash and dilute the sludge on the surface of the screw 26, making it easier for the sludge to be discharged. At the same time, it can also play a certain role in stirring to prevent the sludge from clumping in the sludge silo 17.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
