Description

Technical Field

[0001] This utility model relates to the field of environmental engineering technology, and in particular to a device for treating aquaculture wastewater. Background Technology

[0002] Aquaculture wastewater treatment equipment is used to treat wastewater generated during the aquaculture process to remove pollutants and make it meet discharge standards or reuse requirements. It achieves effective removal of pollutants such as organic matter, ammonia nitrogen, and suspended solids from aquaculture wastewater through a combination of these methods.

[0003] Existing aquaculture wastewater treatment devices can only remove larger solid impurities, and are powerless against fine particles and dissolved pollutants. Moreover, the intercepted solid debris needs to be cleaned regularly, otherwise it is easy to clog the water flow capacity, and the cleaning work is quite cumbersome. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology that cannot filter wastewater faster, the technical problem is to provide a device for rapidly filtering aquaculture wastewater.

[0005] The technical solution is as follows: An aquaculture wastewater treatment device includes a mounting frame. A sludge storage bin is fixedly connected to the mounting frame. A filter box is fixedly connected to the left side of the sludge storage bin. A treatment bin is fixedly connected to the left side of the mounting frame. The bottom of the filter box is connected to the top of the treatment bin. Filter plate A and filter plate B are fixedly connected inside the filter box. Filter plate B is located below filter plate A, and the filter holes of filter plate B are smaller than those of filter plate A, forming a multi-stage primary sieve. Two through holes are opened on the rear side of the filter box. A rotating plate is rotatably connected to the through holes via a rotating shaft. Springs A are installed on both sides of the through holes. One end of spring A is fixedly connected to the filter box, and the other end is fixedly connected to the rotating plate, providing elastic force for the rotating plate to return to its original position. In this device, the sludge storage bin is used to temporarily store aquaculture wastewater. Filter plates A and B can perform multi-stage filtration and interception of impurities in the wastewater. Under the action of spring A, the rotating plate can achieve the diversion or discharge control of impurities.

[0006] Preferably, the system also includes a base. A base is fixedly connected to the front left side of the mounting frame. Two electric push rods are fixedly connected to the base. The telescopic ends of the electric push rods are fixedly connected to the front end of the movable frame. Fixed columns are provided on both sides inside the movable frame. Spring B is sleeved on the fixed columns, with one end fixedly connected to the movable frame and the other end fixedly connected to the vibration motor. When the vibration motor operates and generates vibration, the vibration motor is displaced relative to the movable frame. Spring B undergoes elastic deformation, absorbing vibration energy and thus buffering the vibration generated when the vibration motor operates. The movable frame is slidably connected to the vibration motor via a slide rail. A push plate is fixedly connected to the bottom of the vibration motor. The push plate is tightly fitted with filter plates A and B. Vibration loosens the impurities attached to the filter and promotes the aquaculture wastewater to penetrate the filter more quickly under the action of vibration. The cleaning device consisting of the vibration motor and the push plate is located above filter plates A and B.

[0007] Preferably, the filter box also includes a guide plate, which is fixedly connected to the rear bottom of the filter box to allow the treated wastewater residue to slide to both sides.

[0008] Preferably, an observation window is also included, with the front side of the sludge storage tank having an observation window for observing the internal conditions of the sludge storage tank.

[0009] Preferably, a sealing block is also included, and the filter box and the electric push rod are fixedly connected with the sealing block to prevent wastewater leakage during the treatment of aquaculture wastewater.

[0010] Preferably, a reinforcing ring is also included, which is fixedly connected between the bottom of the filter box and the top of the treatment chamber to enhance the connection stability between the two.

[0011] The beneficial effects of this utility model are: 1. When the treatment of aquaculture wastewater by the two filter plates is completed, the impurities will cause the rotating plate to rotate backward. When the rotating plate rotates backward, it will squeeze the spring A. When the impurities are treated, the spring A will rotate the rotating plate forward, which plays the role of automatically discharging impurities and resetting the rotating plate for cyclical operation, thereby improving the treatment efficiency of aquaculture wastewater and enhancing the reliability and stability of the device operation.

[0012] 2. The left and right vibration of the vibrating motor drives the push plate to push the impurities backward. During vibration, spring B reduces the vibration of the device, which plays a role in cleaning impurities and promoting filtration, thereby improving the filtration effect and treatment efficiency of aquaculture wastewater.

Detailed Implementation

[0017] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0018] Example: Aquaculture wastewater treatment device, such as Figure 1-3As shown, the device includes a mounting frame 1, a sludge storage bin 2, a filter box 3, a treatment bin 4, a filter plate A5, a filter plate B6, a rotating plate 7, and a spring A8. The sludge storage bin 2 is fixedly connected to the mounting frame 1. The filter box 3 is fixedly connected to the left side of the sludge storage bin 2. The treatment bin 4 is fixedly connected to the left side of the mounting frame 1. The bottom of the filter box 3 is connected to the top of the treatment bin 4. The filter plate A5 and the filter plate B6 are fixedly connected inside the filter box 3. The filter plate B6 is located below the filter plate A5, and the filter holes of the filter plate B6 are smaller than those of the filter plate A5. Two through holes are opened on the rear side of the filter box 3. The rotating plate 7 is rotatably connected to the through holes through a rotating shaft. Springs A8 are provided on both sides of the through holes. One end of the spring A8 is fixedly connected to the filter box 3, and the other end is fixedly connected to the rotating plate 7, which provides elastic force for the rotating plate 7 to return to its original position. The system also includes a base 9, electric push rods 10, a movable frame 1101, a vibration motor 12, a spring B13, and a push plate 14. The base 9 is fixedly connected to the front left side of the mounting frame 1. Two electric push rods 10 are fixedly connected to the base 9. The telescopic ends of the electric push rods 10 are fixedly connected to the front end of the movable frame 1101. Fixed columns are provided on both sides inside the movable frame 1101. The spring B13 is sleeved on the fixed columns, with one end fixedly connected to the movable frame 1101 and the other end fixedly connected to the vibration motor 12. The movable frame 1101 is slidably connected to the vibration motor 12 via a slide rail. The push plate 14 is fixedly connected to the bottom of the vibration motor 12, and the push plate 14 is tightly fitted with the filter plate A5 and the filter plate B6. The system also includes a guide plate 15, which is fixedly connected to the bottom rear side of the filter box 3. Finally, the system includes an observation window 16, which is fixedly connected to the front side of the sludge storage tank 2.

[0019] When aquaculture wastewater needs treatment, it is poured into the storage tank 2. After initial sedimentation in the storage tank 2, the wastewater flows into the filter plate 3. Filter plates A5 and B6 filter impurities from the wastewater. After the filter plates A5 and B6 have filtered the wastewater for a preset time, the electric push rod 10 pushes the treatment device backward and simultaneously starts the vibration motor 12 on the moving frame 1101. The vibration generated by the vibration motor 12 drives the push plate 14 to move back and forth, causing the wastewater to pass through the filter more quickly, thereby improving the filtration efficiency. While the vibration motor 12 is vibrating, the springs on the moving frame 1101 act as shock absorbers, reducing the transmission of equipment vibration to the surrounding environment, lowering the vibration amplitude of the entire treatment device, and preventing equipment parts from loosening or being damaged due to long-term vibration. When the processing device is pushed to the rear of the filter box 3 by the electric push rod 10, the push block installed on the movable frame 1101 pushes the impurities attached to the filter towards the rotating plate 7. As the impurities accumulate, the push plate 14 pushes the impurities out of the filter box 3. During this process, the rotating plate 7 rotates backward due to the weight of the impurities, and the spring A8 is squeezed, so that the rotating plate 7 can smoothly discharge the impurities. When the impurities are cleaned by the push plate 14, the spring A8 returns to its original state, pushing the rotating plate 7 to rotate forward and reset. The pushed-out impurities fall onto the guide plate 15 located below the rear of the filter box 3. The guide plate 15 is inclined to guide the impurities to slide down and prevent them from accumulating on the processing chamber 4. After being filtered by the filter plate A5 and the filter plate B6, the aquaculture wastewater flows into the processing chamber 4. The processing chamber 4 performs deep treatment on the wastewater to ensure that the treated aquaculture wastewater meets the relevant discharge standards or reuse requirements, thereby completing the entire treatment process.

[0020] like Figure 1 and Figure 2 As shown, it also includes a sealing block 17, which is fixedly connected to the sliding connection between the filter box 3 and the electric push rod 10. It also includes a reinforcing ring 18, which is fixedly connected between the bottom of the filter box 3 and the top of the processing chamber 4.

[0021] A sealing block 17 is fixedly connected between the filter box 3 and the electric push rod 10 to prevent wastewater leakage during aquaculture wastewater treatment. This sealing block prevents leakage, thus avoiding environmental pollution, protecting the equipment, and ensuring operational safety. A reinforcing ring 18 is fixedly connected between the filter box 3 and the treatment chamber 4 to enhance the strength and stability of the connection structure, extending the equipment's service life and ensuring safe and reliable operation.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
