Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a multi-stage treatment device for aquaculture pond wastewater. Background Technology

[0002] Animal husbandry refers to the artificial raising of animals such as chickens, ducks, and fish to provide food for people. With the development of animal husbandry and the increase in market demand, the scale of animal husbandry is getting larger and larger. A large amount of wastewater is generated in the process of raising animals. In order to avoid pollution from animal husbandry wastewater, it is usually treated.

[0003] During sturgeon farming, the water in the ponds needs to be replaced. However, the wastewater contains a large amount of impurities and harmful substances, so it needs to be treated before it can be discharged properly to prevent the sturgeon wastewater from affecting the external environment.

[0004] According to Chinese Patent Publication No. CN220132023U, a multi-stage filtration aquaculture wastewater treatment device is proposed. Through the design of the filter box, wastewater is introduced into the filter box. A drive motor is activated to rotate the drive screw, causing the coarse filter screen to move. The coarse filter screen filters the wastewater inside the filter box, separating impurities from the wastewater. Moving the coarse filter screen to the top of the filter box allows for cleaning, preventing impurities from affecting wastewater treatment. Through the design of the mixing box, a servo motor is activated to rotate the stirring rod, allowing the wastewater to mix with chemical agents for wastewater treatment. A heating wire heats the wastewater, improving the mixing effect of the wastewater and chemical agents and enhancing the wastewater treatment efficiency. During the mixing of wastewater and chemical agents, the generated exhaust gas is treated through a purification cylinder, allowing the exhaust gas to be discharged without impacting the surrounding environment.

[0005] The application document describes a method for filtering wastewater using a coarse filter screen. However, in practice, cleaning the coarse filter screen requires moving it to the top and cleaning that top is difficult. This makes it troublesome to remove impurities stuck inside the screen and can easily result in incomplete cleaning. Furthermore, cleaning the screen requires prolonged shutdown of the treatment device, significantly impacting its efficiency. Therefore, this paper proposes a multi-stage wastewater treatment device for aquaculture ponds to address these issues. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figures 1-6 As shown, the present invention proposes a multi-stage wastewater treatment device for aquaculture ponds, including a base plate 1, a filter box 2 on the top of the base plate 1, and a filter mechanism 3 inside the filter box 2.

[0029] In this invention, the filter box 2 can be installed on the base plate 1, and the filter box 2 and the filter mechanism 3 can filter the tailwater of sturgeon farming. After filtration is completed, the coarse filter screen can be disassembled and replaced through the filter mechanism 3, which facilitates quick cleaning of the coarse filter screen. Directly disassembling and cleaning the coarse filter screen can ensure the cleaning effect of the coarse filter screen. At the same time, installing a new coarse filter screen can minimize the downtime of the treatment device when cleaning the coarse filter screen, which greatly improves the treatment efficiency of the tailwater.

[0030] In an optional embodiment, the filter mechanism 3 includes a support frame 31, a mounting frame 32, a filter plate 33, two handles 34, a mounting component 35, a guide component 36, and a fixing component 37. The support frame 31 is fixedly installed inside the filter box 2. The mounting frame 32 is placed on top of the support frame 31. The outer side of the mounting frame 32 is slidably connected to the inner side of the filter box 2. The filter plate 33 is slidably connected to the inside of the mounting frame 32. The two handles 34 are both fixedly installed on the top of the mounting frame 32 and are evenly distributed. The mounting component 35 is disposed on the outer end face of the filter plate 33. The mounting frame 32 is connected to the filter plate 33 through the mounting component 35. The guide component 36 is disposed on the inner side of the filter box 2. The fixing component 37 is disposed on the top of the mounting frame 32. The filter box 2 is connected to the mounting frame 32 through the fixing component 37.

[0031] It should be noted that the filter plate 33 can be installed inside the mounting frame 32 using the mounting component 35, and the support frame 31 can provide stable support for the mounting frame 32, thereby ensuring that the mounting frame 32 is located in the middle of the filter box 2, and further ensuring that the filter plate 33 is located in the middle of the filter box 2. The filter plate 33 filters the tailwater of sturgeon farming. When it is necessary to clean the filter plate 33, first, let the fixing component 37 lose its fixation to the mounting frame 32, and then directly pull the two handles 34 to remove the mounting frame 32 from the inside of the filter box 2. This allows the filter plate 33 and the mounting component 35 to be removed from the inside of the filter box 2. At this time, the filter plate 33 can be disassembled using the mounting component 35, and a new filter plate 33 can also be installed. After the new filter plate 33 is installed, the mounting frame 32 and the new filter plate 33 can be directly installed into the inside of the filter box 2 using the two handles 34, and then fixed using the fixing component 37.

[0032] By disassembling the old filter plate 33, it can be thoroughly cleaned. For example, backwashing can be used to remove impurities stuck inside the old filter plate 33, thus ensuring the cleaning effect of the old filter plate 33 as much as possible. While the old filter plate 33 is being cleaned, the wastewater can continue to be treated through the new filter plate 33 without shutting down the treatment device, which greatly improves the wastewater treatment effect of the treatment device.

[0033] In an optional embodiment, the mounting assembly 35 includes two mounting plates 351 and two mounting bolts 352. The two mounting plates 351 are fixedly mounted on the left and right sides of the filter plate 33 and are symmetrically distributed. The two mounting bolts 352 are respectively located at the bottom of the two mounting plates 351 and extend into the interior of the mounting frame 32. Both mounting bolts 352 are threadedly connected to the mounting frame 32.

[0034] It should be noted that when it is necessary to remove the filter plate 33 from the inside of the mounting frame 32, simply rotate the two mounting bolts 352 to disengage them from the mounting plate 351, and then push the filter plate 33 downwards to remove it from the inside of the mounting frame 32.

[0035] In addition, when installing the filter plate 33 into the mounting frame 32, the filter plate 33 needs to be slidably connected to the inside of the mounting frame 32 from the bottom, and then the two mounting bolts 352 are rotated in the opposite direction so that the two mounting bolts 352 are engaged with the mounting plate 351, and the filter plate 33 can be installed into the inside of the mounting frame 32.

[0036] In an optional embodiment, each of the two mounting plates 351 has a mounting hole extending through to its top at its bottom, and two mounting bolts 352 are located inside the two mounting holes and are movably connected to the two mounting holes respectively.

[0037] It should be noted that the two mounting holes ensure the stable installation and removal of the two mounting bolts 352, thereby ensuring the stable installation and removal of the filter plate 33.

[0038] In an optional embodiment, the guide assembly 36 includes two guide grooves 361 and two guide blocks 362. The two guide grooves 361 are respectively opened on the left and right side walls of the inner cavity of the filter box 2 and are symmetrically distributed. The tops of the two guide grooves 361 are connected to the outside. The two guide blocks 362 are respectively fixedly installed on the left and right sides of the mounting frame 32 and are symmetrically distributed. The two guide blocks 362 are slidably connected to the inside of the two guide grooves 361.

[0039] It should be noted that when the mounting frame 32 and filter plate 33 are installed inside the filter box 2, the mounting frame 32 can be guided by the two guide grooves 361 and the two guide blocks 362 to ensure the stability of the mounting frame 32 and its connecting structure during installation, and to prevent the mounting frame 32 and its connecting structure from tilting during installation, which would affect the normal installation of the mounting frame 32 and its connecting structure.

[0040] In an optional embodiment, the fixing assembly 37 includes two fixing plates 371, two threaded grooves 372, two threaded rods 373, and two knobs 374. The two fixing plates 371 are respectively fixedly installed on the front and back sides of the top of the mounting frame 32 and are symmetrically distributed. The two threaded grooves 372 are respectively opened on the front and back side walls of the inner cavity of the filter box 2. The two threaded rods 373 are respectively located on the opposite side of the two fixing plates 371 and extend into the interior of the two threaded grooves 372. The two threaded rods 373 are respectively threadedly connected to the two threaded grooves 372. The two knobs 374 are respectively fixedly installed on the opposite side of the two threaded rods 373.

[0041] It should be noted that when it is necessary to remove the mounting frame 32 and filter plate 33 from the inside of the filter box 2, the knob 374 needs to be turned. The knob 374 will drive the threaded rod 373 to rotate, so that the threaded rod 373 disengages from the threaded groove 372, and then the mounting frame 32 and filter plate 33 can be removed from the inside of the filter box 2.

[0042] In addition, when the mounting frame 32 and the filter plate 33 are installed inside the filter box 2, when the bottom of the mounting frame 32 abuts against the top of the support frame 31, the knob 374 can be rotated in the opposite direction to make the threaded rod 373 rotate in the opposite direction. When the threaded rod 373 engages with the threaded groove 372, the mounting frame 32 can be fixed by the fixing plate 371, the threaded groove 372 and the threaded rod 373, preventing the mounting frame 32 and its connecting structure from shaking or tilting during the filtration process, thereby further ensuring the filtration effect of the filter plate 33.

[0043] In an optional embodiment, a mixing box 4 is fixedly installed on the top of the base plate 1, a purification box 5 is fixedly installed on the top of the base plate 1, and a plurality of evenly distributed bases are provided on the bottom of the base plate 1.

[0044] It should be noted that the top of the base plate 1 is equipped with a first pump body located on the front of the mixing tank 4. The first pump body is connected to the filter tank 2 and the mixing tank 4 through a first connecting pipe. The top of the mixing tank 4 is connected to a feeding pipe, and the top of the mixing tank 4 is equipped with a stirring motor. The output shaft of the stirring motor is equipped with a stirring rod extending into the mixing tank 4. Multiple evenly distributed stirring blades are provided on the outside of the stirring rod. After the sewage filtration is completed, the filtered water can be sent into the mixing tank 4 through the first pump body and the first connecting pipe. Chemical agents can be added into the mixing tank 4 through the feeding pipe. By starting the stirring motor, the multiple stirring blades can be driven to rotate. The rotation of the multiple stirring blades can mix the filtered sewage with the chemical agents. The mixing tank 4 is equipped with a heating wire, which can heat the wastewater to improve the mixing effect of the wastewater and chemical agents and improve the wastewater treatment effect. The top of the mixing tank 4 is connected to a purification cylinder. When the wastewater and chemical agents are mixed, the generated exhaust gas is treated through the purification cylinder so that the exhaust gas can be discharged to prevent it from affecting the nearby environment.

[0045] In addition, a second pump body is installed on the top of the purification tank 5. The second pump body is connected to the mixing tank 4 and the purification tank 5 through a second connecting pipe. The purification tank 5 has a first purification layer, a second purification layer and a third purification layer arranged from top to bottom. The first purification layer is a fine mesh filter structure, the second purification layer is an activated carbon purification layer, and the third purification layer is made of MBR membrane material. The first purification layer can filter out the fine impurities that leak out through the filter plate 33. The second purification layer is filled with activated carbon, which is mainly used to decolorize, remove odors and remove organic matter from the filtered water. The third purification layer can ensure stable water quality, and the microorganisms are completely trapped in the reactor. The system maintains a high concentration of microorganisms, increases the volumetric load, improves the removal efficiency of microbial pollution, and has a strong ability to withstand shock loads.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can 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.
