Description

Technical Field

[0001] This utility model relates to the field of aquaculture wastewater treatment technology, specifically an integrated treatment device for industrialized shrimp farming wastewater. Background Technology

[0002] Shrimp tail water treatment devices play a crucial role in factory farming. These devices not only improve the recycling rate of water resources and reduce farming costs, but also optimize the water quality, ensure the healthy growth of shrimp, and increase yield and quality. They mainly use a multi-stage filtration system to effectively remove solid waste, suspended solids, and harmful substances from the tail water, significantly reducing environmental pollution.

[0003] In existing technologies, traditional wastewater treatment devices mainly consist of aquaculture ponds, filtration ponds, aeration ponds, and disinfection ponds. The aquaculture ponds are used for the breeding and growth of shrimp and also serve as the source of wastewater. The filtration ponds further intercept fine particulate matter and improve water clarity. The aeration ponds increase dissolved oxygen in the water, promoting the decomposition of organic matter and the metabolic activities of microorganisms. The disinfection ponds use chemical or physical methods to kill pathogenic microorganisms in the water, ensuring that the wastewater meets the standards for discharge or reuse. All parts work together to achieve effective purification and treatment of wastewater.

[0004] However, when using traditional wastewater treatment devices, some shrimp shells and dead shrimp will settle at the bottom of the aquaculture pond. If these larger sediments are not cleaned in time, they will cause water quality deterioration and produce harmful gases such as hydrogen sulfide and ammonia, which will affect the healthy growth of shrimp. At the same time, filtering large sediments will cause filter screens or pipes to become clogged, increasing the difficulty of equipment maintenance and affecting the overall purification efficiency. Therefore, this utility model proposes an integrated wastewater treatment device for factory-scale shrimp farming to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated treatment device for the tailwater of industrialized shrimp farming to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated treatment device for shrimp tail water in industrialized farming, comprising: a farming pond, a suction pipe installed at the bottom and above the bottom of the farming pond, a first drainage pipe connected to the bottom of the farming pond, a pre-filter installed on the bottom surface of the farming pond, a suction pipe installed directly above the pre-filter, and a collection frame installed on one side wall of the farming pond.

[0007] The coarse filter box has a coarse filter screen on top and a second drain pipe at the bottom.

[0008] Preferably, the aquaculture pond has a cylindrical structure, and several circumferentially spaced support columns are fixedly installed at the bottom of the aquaculture pond. Holes are opened at the bottom of the aquaculture pond, and support baffles are fixedly installed in the holes. A fixing block is fixedly installed on one side wall of the aquaculture pond, and a slot is opened on the surface of the fixing block.

[0009] Preferably, the surface of the support baffle is provided with a plurality of circumferentially spaced flow holes, the outer surface of the support baffle is provided with a plurality of threaded holes, a connecting pipe is provided directly below the support baffle, the upper end of the connecting pipe is fixedly installed at the bottom of the aquaculture pond, and the lower end of the connecting pipe is fixedly installed with a first drain pipe.

[0010] Preferably, a splash guard is fixedly installed on the outer wall of the end of the first drain pipe away from the connecting pipe, and the entire splash guard is located above the coarse filter screen.

[0011] Preferably, the suction pipe is located directly above the pre-filter screen, and several suction grooves are provided on the lower side wall of the suction pipe. A water pump is connected to the end of the suction pipe away from the pre-filter screen, and a third drain pipe is connected above the water pump. A collection frame is provided directly below the outlet end of the third drain pipe, and a locking block is fixedly installed at one end of the collection frame. The locking block can be locked into the slot opened on the surface of the fixing block.

[0012] Preferably, the coarse filter box is cylindrical in shape, with a coarse filter screen at the top and a fixing groove at the bottom of the frame of the coarse filter screen. The fixing groove can be locked onto the top of the coarse filter box. A hole is provided on the lower side wall of the coarse filter box, and a second drain pipe is installed in the hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention proposes an integrated treatment device for shrimp farming tailwater. During operation, a pre-filter at the bottom of the farming pond traps shrimp shells and dead shrimp, which then settle to the bottom surface. A suction pipe then extracts these shrimp shells and dead shrimp from the bottom of the pre-filter and transports them to a collection frame installed on the side wall of the farming pond. This process cleans and filters larger sediments in the pond. The tailwater is then transported from the bottom of the pond to a coarse filter box for further coarse filtration. After multiple filtrations, larger particles and suspended solids in the tailwater are effectively removed, reducing the workload of subsequent microfiltration processes. This avoids the problem of large particles clogging the microfiltration equipment and affecting the filtration effect. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1: Please refer to Figures 1 to 4 This utility model provides a technical solution: an integrated treatment device for shrimp tail water in industrialized shrimp farming, including: a breeding pond 1, a suction pipe 2 with a suction pipe 2 at the bottom and a first drainage pipe 3 connected to the bottom of the breeding pond 1, a pre-filter 4 with a pre-filter 4 with the suction pipe 2 directly above the pre-filter 4, and a collection frame 5 with a side wall of the breeding pond 1.

[0022] The coarse filter box 6 has a coarse filter screen 7 on top and a second drain pipe 8 at the bottom.

[0023] During use, the pre-filter 4 located at the bottom of the aquaculture pond 1 intercepts shrimp shells and dead shrimp in the aquaculture pond 1, and the shrimp shells and dead shrimp settle to the bottom surface of the pre-filter 4. At this time, the suction pipe 2 is controlled to extract the shrimp shells and dead shrimp at the bottom of the pre-filter 4 and transport them to the collection frame 5 installed on the side wall of the aquaculture pond 1, thereby cleaning and filtering the larger sediments in the aquaculture pond 1. Then, the tailwater is transported from the bottom of the aquaculture pond 1 to the coarse filter box 6 for coarse filtration again. After multiple filtrations, the larger particles and suspended solids in the tailwater are effectively removed, thereby reducing the workload of the subsequent microfiltration process. This avoids the problem of large particles clogging the microfiltration equipment and affecting the filtration effect.

[0024] Example 2: Based on Example 1, a suction pipe 2 is provided to improve the overall filtration effect. The suction pipe 2 is located directly above the pre-filter screen 4. Several suction grooves 15 are opened on the lower side wall of the suction pipe 2. A water pump 16 is connected to the end of the suction pipe 2 away from the pre-filter screen 4. A third drain pipe 17 is connected above the water pump 16. A collection frame 5 is set directly below the outlet end of the third drain pipe 17. A locking block 13 is fixedly installed at one end of the collection frame 5. The locking block 13 can be locked into the locking groove opened on the surface of the fixing block 10. A splash guard 14 is fixedly installed on the outer wall of the end of the first drain pipe 3 away from the connecting pipe 12. The splash guard 14 is located above the coarse filter screen 7.

[0025] To improve overall filtration, a pre-filter 4 is fixedly installed above the support baffle 9 at the bottom of the aquaculture pond 1. Under the action of the pre-filter 4, the shrimp shells and dead shrimp that have settled at the bottom of the aquaculture pond 1 are blocked on the surface of the pre-filter 4. Under the action of water flow and gravity, the sediment will accumulate on the bottom surface of the pre-filter 4. At this time, the water pump 16 is driven to control the suction pipe 2 to extract the sediment on the surface of the pre-filter 4 and discharge the sediment into the collection frame 5 through the third drain pipe 17. The sediment will be filtered out in the collection frame 5, and the aquaculture water will flow back into the aquaculture pond 1. This removes the large volume sediment at the bottom of the aquaculture pond 1 and prevents the large volume sediment from entering the subsequent filtration process and causing the filter holes to become clogged, thus affecting the overall filtration efficiency.

[0026] The coarse filter box 6 has a cylindrical structure. A coarse filter screen 7 is installed at the upper end of the coarse filter box 6. A fixing groove is opened at the lower end of the frame of the coarse filter screen 7. The fixing groove can be locked at the upper end of the coarse filter box 6. A hole is opened on the lower side wall of the coarse filter box 6, and a second drain pipe 8 is installed in the hole. A number of circumferentially spaced flow holes 11 are opened on the surface of the support baffle 9. A number of threaded holes are opened on the outer surface of the support baffle 9. A connecting pipe 12 is installed directly below the support baffle 9. The upper end of the connecting pipe 12 is fixedly installed at the bottom of the breeding pond 1, and the lower end of the connecting pipe 12 is fixedly installed with the first drain pipe 3.

[0027] During the filtration process, the wastewater at the bottom of the aquaculture tank 1 is connected to the first drainage pipe 3 via the connecting pipe 12 at the bottom of the aquaculture tank 1, so that the wastewater at the bottom of the aquaculture tank 1 is discharged into the coarse filter box 6. After being filtered by the coarse filter screen 7 on the surface of the coarse filter box 6, larger volumes of sediment in the wastewater can be filtered out. Furthermore, the coarse filter screen 7 is fixed at the top of the coarse filter box 6, and the operator can directly remove the coarse filter screen 7 for disassembly, which facilitates the replacement of the coarse filter screen 7 and improves the overall filtration efficiency.

[0028] Example 3: Based on Example 2, a breeding pond 1 is provided to facilitate the replacement of the collection frame 5. The breeding pond 1 is cylindrical in shape. Several circumferentially spaced support columns are fixedly installed at the bottom of the breeding pond 1. A hole is opened at the bottom of the breeding pond 1, and a support baffle 9 is fixedly installed in the hole. A fixing block 10 is fixedly installed on one side wall of the breeding pond 1. The surface of the fixing block 10 is provided with a slot.

[0029] To facilitate the replacement of the collection frame 5, a slot is provided on the surface of the fixing block 10 located on the side wall of the breeding pond 1. The slot can be used to insert the locking block 13 at one end of the collection frame 5. If it is necessary to clean or replace the collection frame 5, simply pull the locking block 13 out of the slot. The whole process is simple and easy to operate.

[0030] Working principle: In actual use, the pre-filter 4 located at the bottom of the aquaculture pond 1 will intercept the shrimp shells and dead shrimp in the aquaculture pond 1 on the pre-filter 4, and the shrimp shells and dead shrimp will settle to the bottom surface of the pre-filter 4. At this time, the suction pipe 2 is controlled to extract the shrimp shells and dead shrimp at the bottom of the pre-filter 4 and transport them to the collection frame 5 installed on the side wall of the aquaculture pond 1, thereby cleaning and filtering the larger sediments in the aquaculture pond 1. Then, the tailwater is transported from the bottom of the aquaculture pond 1 to the coarse filter box 6 for coarse filtration again. After multiple filtrations, the larger particles and suspended solids in the tailwater are effectively removed, thereby reducing the workload of the subsequent microfiltration process. This avoids the problem of large particles clogging the microfiltration equipment and affecting the filtration effect.

[0031] 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.
