Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture equipment, in particular to a purification device for aquaculture. Background Technique

[0002] Aquaculture is a production activity of artificially controlling the reproduction, cultivation and harvesting of aquatic animals and plants. Aquatic organisms such as fish, shrimps, soft-shelled turtles, etc. generally include the whole process of growing aquatic products from fry under artificial feeding and management. When carrying out aquaculture, aquatic products are usually fed through a pool. However, due to the easy accumulation of uneaten feed residues and excreta produced after eating at the bottom of the aquaculture pond during the feeding process, it is easy to cause water quality deterioration. Therefore, it is necessary to carry out purification treatment regularly. If all the liquid in the aquaculture pond is discharged and replaced with new water during the purification process, it will lead to waste of resources and increased costs. For this reason, based on the concept of environmental protection and cost saving, the utility model proposes a purification device for aquaculture, so that the water after purification treatment can still be recycled.

Obviously, the described embodiments are only some, rather than all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0029] Please refer toFigure 1-2 , the present utility model provides a technical solution: a purification device for aquaculture, including a purification component 3 externally connected to an aquaculture pond 1. The installation height of the aquaculture pond 1 is higher than that of the purification component 3. A "reverse V"-shaped tip boss 11 is provided in the middle of the aquaculture pond 1. An inclined platform 12 is provided from the front side to the rear side of the tip boss 11. A screening plate 13 is provided on one side of the aquaculture pond 1 from the lowest point of the inclined platform 12 to the pool wall. A blanking pipe 14 is installed below the screening plate 13;

[0030] One end of the purification component 3 is connected to the blanking pipe 14, and the other end is reconnected to the aquaculture pond 1 outward. The purification component 3 includes a purification chamber 34. From bottom to top in the purification chamber 34, there are successively a first grid plate layer 341, a first high-precision PP cotton layer 342, a first filter membrane layer 343, a CaSO3 layer 344, a KDF medium layer 345, a medical stone layer 346, an activated carbon layer 347, a second filter membrane layer 348, a second high-precision PP cotton layer 349, and a second grid plate layer 340. It is defined that: both the first filter membrane layer 343 and the second filter membrane layer 348 are cellulose-based nanofiltration membranes. The through-hole diameter of the first grid plate layer 341 is larger than that of the second filter membrane layer 340. The through-hole diameter of the first high-precision PP cotton layer 342 is larger than that of the second high-precision PP cotton layer 349. The through-hole diameter of the first filter membrane layer 343 is larger than that of the second grid plate layer 348. The first connecting pipe 32 of the purification component 3 accesses the liquid from the aquaculture pond 1 and conveys it to the lower part of the first grid plate layer 341. In order to facilitate the control of the liquid flow rate of the feed, a small-diameter access pipe 31 is provided at the feed front end of the first connecting pipe 32. The water flow rate of the small-diameter access pipe 31 is smaller than that of the first connecting pipe 32. At the same time, for separate flow, the purification component 3 and the blanking pipe 14 are connected through a tee pipe 2. One side of the tee pipe 2 is connected to the small-diameter access pipe 31, one side is connected to the blanking pipe 14, and the other side is externally connected to a liquid outlet pipe. The filtered liquid flows out through the upper second connecting pipe 35 and is finally pumped into the aquaculture pond 1. In order to enhance the liquid pumping effect, a liquid pumping pump 7 is provided between the second connecting pipe 35 and the aquaculture pond 1. At the same time, the outer end of the second connecting pipe 35 is connected to a small-diameter outlet pipe 36. The water flow rate of the small-diameter outlet pipe 36 is smaller than that of the second connecting pipe 35. The height of the first connecting pipe 32 is higher than that of the second connecting pipe 35;

[0031] To enable the liquid to enter and be filtered better, see the appendix Figure 1 , a multi-head water outlet pipe 33 is provided at the feed end of the first connecting pipe 32. The multi-head water outlet pipe 33 is arranged below the first grid plate layer 341. The multi-head water outlet pipe 33 has at least two water outlet heads;

[0032] In the above description, the small-diameter outlet pipe 36 is externally connected to the first transition pipe 4, the water outlet end of the first transition pipe 4 is connected to the bottom of the buffer tank 5, a second transition pipe 6 is externally connected above the buffer tank 5, the second transition pipe 6 is connected to the third transition pipe 8, the end of the third transition pipe 8 is connected above the tip boss 11 of the aquaculture pond 1, and a liquid extraction pump 7 is arranged between the second transition pipe 6 and the third transition pipe 8;

[0033] In order to better achieve segmented control of the liquid flow, electric control valves are provided on the feeding pipe 14, the three-way pipe 2, the first connecting pipe 32, the second connecting pipe 35, the first transition pipe 4, the second transition pipe 6 and the third transition pipe 8.

[0034] A specific application of this embodiment is: The utility model is applicable to the water quality treatment and purification of aquaculture purification equipment. During use, the water discharged from the aquaculture pond is recycled. It should be noted that the aquaculture pond set in this scheme is preferably selected to have a middle tip boss, with inclined platforms on both sides. The direction of the inclined platforms is from front to back and the lowest point flows to the screening plate, so as to facilitate the residues and excreta deposited at the bottom to flow above the screening plate. In this way, when discharging, the food residues and excreta can be preferentially discharged along with the water flow. Compared with the flat ground, it has more advantages in collecting impurities;

[0035] When the liquid flows downward with impurities, the electric control valve of the feeding pipe and the electric control valve of the first connecting pipe are opened, so that the liquid is sent to the bottom of the purification chamber through the small-diameter access pipe - the first connecting pipe - the multi-outlet water pipe. Since the filter layer for filtration is arranged in the middle of the purification chamber, when the liquid needs to flow out from the second connecting pipe above, it needs to be transmitted layer by layer upward. When overflowing upward, it sequentially passes through the first grid plate layer, the first high-precision PP cotton layer, the first filter membrane layer, the CaSO 3c layer, the KDF medium layer, the medical stone layer, the activated carbon layer, the second filter membrane layer, the second high-precision PP cotton layer, the second grid plate layer. In order to achieve effective filtration, both the first filter membrane layer and the second filter membrane layer are cellulose-based nanofiltration membranes. The through-hole diameter of the first grid plate layer is larger than that of the second filter membrane layer, the through-hole diameter of the first high-precision PP cotton layer is larger than that of the second high-precision PP cotton layer, and the through-hole diameter of the first filter membrane layer is larger than that of the second grid plate layer. After the liquid is treated, it overflows to the second connecting pipe, and then passes through the small-diameter outlet pipe - the first - the first transition pipe - the buffer tank - the second transition pipe - the liquid extraction pump - the third transition pipe - and returns to the aquaculture pond for reuse. The buffer tank is used for further precipitation, and the upper clear liquid is taken for use, making the recycled water quality better. In addition, the relatively turbid water quality can also flow out through the liquid outlet pipe end of the three-way pipe, making the water purification treatment more effective.
