Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, and particularly relates to a circulating water treatment device for shrimp aquaculture tail water. Background Art

[0002] With the rapid development of the shrimp aquaculture industry, if the tail water generated during the aquaculture process is directly discharged without treatment, it will cause pollution to the environment. At the same time, the waste of water resources also exacerbates the problem of water resource shortage.

[0003] In the prior art, in order to improve the utilization rate of water resources, a circulating water treatment device is used to purify the tail water of shrimp aquaculture, so that it can re-enter the aquaculture pond for shrimp farming. However, common circulating water treatment devices generally screen and remove feces and feed residues by sedimentation. When there are too many impurities in the sedimentation tank, they need to be salvaged and cleaned. The operation is cumbersome and the maintenance cost is high. If not cleaned in time, the water will impact the impurities, causing them to disperse and even break continuously in the device, affecting the subsequent purification effect. How to invent a circulating water treatment device for shrimp aquaculture tail water to improve these problems has become an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a circulating water treatment device for shrimp aquaculture tail water, aiming to improve the problems that the common circulating water treatment device has too many impurities and needs to be salvaged and cleaned, the operation is cumbersome and the maintenance cost is high, and the water will impact the impurities, causing them to disperse and even break continuously in the device, affecting the subsequent purification effect.

[0005] The utility model is realized as follows:

A circulating pipe is installed on one side inner wall of the device body close to the stirring shaft. An aggregate box is installed on the outer wall of the device body close to the tail water pipe. A fixing plate is fixedly connected to the inner wall of the device body. Driving grooves are opened in the two sides of the device body. An adjusting groove is opened in the inner wall of the driving groove. A limiting groove is opened at the upper end of the adjusting groove. A motor is installed on the outer wall of one side of the device body;

[0007] Both ends of the rotating shaft are fixedly connected to driving shafts that are rotatably connected to the inner wall of the driving groove. A waterproof bearing that is fixedly connected to the inner wall of the device body is installed on the outer wall of the driving shaft. A gear is provided on one outer wall of the rotating shaft, and a sealing plate is provided on the outer wall of the rotating shaft.

[0008] The outer wall of the sealing block is inserted into the inner wall of the material discharge port. Rack bars that are slidably connected to the adjusting grooves are provided on both sides of the upper end of the sealing block.

[0009] Preferably, the aperture of the sieve mesh is larger than that of the filter mesh. The sieve mesh is a special-shaped mesh plate with an upper arc and a lower inclined surface. The inner wall of the fixing frame is rotatably connected to the outer wall of the upper end of the stirring shaft.

[0010] By adopting the above technical solution, the tail water enters the interior of the device body through the tail water pipeline. The special-shaped sieve mesh is designed to screen out feces and residual feed in the flowing water body, and it falls into the precipitation slope under the action of the inclined surface at the lower end of the sieve mesh, realizing the screening and accumulation of impurities. Then, the tail water passes through the filter mesh for secondary filtration to remove smaller microorganisms and impurities and enters the stirring area. Chemicals are put into the stirring area to neutralize the nitrogen and phosphorus elements in the water body to avoid water eutrophication. At the same time, under the action of the water flow, the stirring shaft is forced to rotate continuously so that the drug is fully mixed with the water body. Then, ultraviolet rays are released by the ultraviolet lamp tube to further kill the microorganisms in the water body, improving the purification effect. Finally, the water body re-enters the shrimp culture pond through the circulation pipe.

[0011] Preferably, the aperture of the sieve mesh is larger than that of the filter mesh. The sieve mesh is a special-shaped mesh plate with an upper arc and a lower inclined surface. The inner wall of the fixing frame is rotatably connected to the outer wall of the upper end of the stirring shaft.

[0012] Preferably, a number of holes are provided in the bottom wall of the aggregate box. The output end of the motor is fixedly connected to one end of one of the driving shafts.

[0013] Preferably, the inner wall of the gear is fixedly connected to the outer wall of the driving shaft, and the gear is meshed with the rack bar.

[0014] Preferably, the sealing block is located inside the aggregate box, and the outer wall of the sealing block is fixedly connected to one end of the rack bar.

[0015] Preferably, the outer wall of the rack bar is slidably connected to the inner wall of the adjusting groove, and a limit block that is slidably connected to the inner wall of the limit groove is fixedly connected to one end of the rack bar.

[0016] Preferably, one end of the sealing plate is fixedly connected to the outer wall of the rotating shaft, an elastic sealing pad is installed at the end of the sealing plate, and the bottom end of the sealing plate abuts against the bottom wall of the precipitation slope in the vertical state.

[0017] By adopting the above technical solution, when there is too much sundry accumulated in the sediment slope, the motor is started at this time to drive the sealing plate to rotate by the rotating shaft, so that the lower end thereof abuts against the lower inner wall of the sediment slope. At the same time, the sealing block is disengaged from the sealing of the material discharge port. At this time, the water body located between the material discharge port and the sealing plate carries impurities and flows to the outer aggregate box. At the same time, a part of the water body flows out from the gap between the sealing plate and the device body and the gap between the rotating shaft and the fixing plate, so as to flush out some of the sundries remaining on the material discharge port, regularly clean the sundries in the sediment slope, and improve the tail water treatment effect of the device body.

[0018] The beneficial effects of the present utility model are as follows:

[0019] The stirring shaft provided stirs the surrounding water body under the action of the water flow, so that the drug can be evenly diffused in the water body, improving the purification effect. At the same time, the specially-shaped designed sieve net plays a guiding role in screening out impurities, so that the impurities are concentrated in the sediment slope, avoiding the further pollution of the water body caused by the fragmentation of the impurities under the action of the water flow, thereby reducing the purification difficulty. At the same time, the provided sealing plate and the sealing block cooperate with each other to open the material discharge port when there is too much impurity accumulation in the sediment slope, so that the impurities can quickly fall into the aggregate box under the action of the water flow for collection, realizing the cleaning of the sundries without affecting the operation of the device, reducing the subsequent maintenance cost and improving the subsequent water purification effect.

[0032] Furthermore, the aperture of the sieve mesh 2 is larger than that of the filter mesh 4. The sieve mesh 2 is a special-shaped mesh plate with an upper arc and a lower inclined surface. The inner wall of the fixing frame 5 is rotatably connected to the outer wall of the upper end of the stirring shaft 6.

[0033] It should be noted that: the tail water enters the interior of the device body 1 through the tail water pipe 9. The feces and residual feed in the flowing water body are screened out by the designed special-shaped sieve mesh 2, and are washed towards the sedimentation slope 3 under the action of the inclined surface at the lower end of the sieve mesh 2. At the same time, the design of the fixed plate 11 avoids the agitation of the water body on the impurities at the bottom, so that they accumulate in the sedimentation slope 3 under the action of gravity. Then the tail water passes through the filter mesh 4 for secondary filtration to remove smaller microorganisms and impurities and enters the stirring area. Drugs are put into the stirring area to neutralize the nitrogen and phosphorus elements in the water body to avoid water eutrophication. At the same time, under the action of the water flow, the stirring shaft 6 is forced to rotate continuously so that the surrounding drugs are fully mixed with the water body, improving the purification effect of the water body. And under the action of the ultraviolet lamp tube 7, ultraviolet rays are released to further kill the microorganisms in the water body, improving the purification effect.

[0034] Furthermore, a number of holes are provided in the bottom wall of the aggregate box 12. The output end of the motor 13 is fixedly connected to one end of one of the drive shafts 19.

The bottom end of the sealing plate 18 abuts against the bottom wall of the sedimentation slope 3 in the vertical state.

[0035] It should be noted that when the sundries accumulated in the precipitation slope 3 are about to overflow, the motor 13 is started to drive the sealing plate 18 to rotate by the rotating shaft 17, so that the lower end thereof abuts against the lower inner wall of the precipitation slope 3 to block the water body. At the same time, the gear 21 on the return drive shaft 19 can be engaged with the rack 22 to separate the sealing block 24 from the material outlet 25. At this time, the water body between the material outlet 25 and the sealing block 24 carries impurities and flows to the outer aggregate box 12. At the same time, a part of the water body flows out from the gap between the sealing plate 18 and the device body 1 and the gap between the rotating shaft 17 and the fixing plate 11, so as to flush out some of the sundries remaining on the material outlet 25, improve the impurity removal effect, and avoid excessive impurities being continuously stirred and broken in the water body to pollute the water body. In this way, the sundries can be cleaned without affecting the operation of the device, and the subsequent purification effect can be improved.

[0036] The working principle of this shrimp culture tail water recycling treatment device:

[0037] The tail water enters the interior of the device body 1 through the tail water pipe 9. The feces and residual feed in the flowing water body are screened out by the designed special-shaped screen 2, and are washed towards the precipitation slope 3 under the action of the inclined plane at the lower end of the screen 2. At the same time, the design of the set fixing plate 11 avoids the water body from stirring the impurities at the bottom, so that they are accumulated in the precipitation slope 3 under the action of gravity. Then, the tail water passes through the filter screen 4 for secondary filtration to remove smaller microorganisms and impurities and enters the stirring area. Drugs are put into the stirring area to neutralize the nitrogen and phosphorus elements in the water body to avoid water eutrophication. At the same time, under the action of the water flow, the stirring shaft 6 is forced to rotate continuously to fully mix the surrounding drugs with the water body, improve the purification effect of the water body, and further kill the microorganisms in the water body by releasing ultraviolet rays under the action of the ultraviolet lamp tube 7. Then, the purified water body is re-introduced into the aquaculture pond through the circulation pipe 10. When the sundries accumulated in the precipitation slope 3 are about to overflow, the motor 13 is started to drive the sealing plate 18 to rotate by the rotating shaft 17, so that the lower end thereof abuts against the lower inner wall of the precipitation slope 3 to block the water body. At the same time, the gear 21 on the return drive shaft 19 can be engaged with the rack 22 to separate the sealing block 24 from the material outlet 25. At this time, the water body between the material outlet 25 and the sealing block 24 carries impurities and flows to the outer aggregate box 12. At the same time, a part of the water body flows out from the gap between the sealing plate 18 and the device body 1 and the gap between the rotating shaft 17 and the fixing plate 11, so as to flush out some of the sundries remaining on the material outlet 25, improve the impurity removal effect, and avoid excessive impurities being continuously stirred and broken in the water body to pollute the water body. In this way, the sundries can be cleaned without affecting the operation of the device, and the subsequent purification effect can be improved.

[0038] It should be noted that the specific model and specification of the motor need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

For those skilled in the art, the present utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
