Description

A slimming fish breeding device

Technical Field

The invention belongs to the technical field of slimming fish breeding, and in particular relates to a slimming fish breeding device.

Background technique

Slimming fish farming is a farming method used to improve the quality of fish. During the farming process, it is necessary to select finished fish and change their original farming environment, as well as control the feeding amount, so as to improve the metabolism of the finished fish and consume some of their own fat, thereby improving the taste of the finished fish meat when eaten.

Slimming fish farming has high requirements for the environment, especially water quality. Although slimming fish are usually farmed in flowing and clean pond water, the slimming fish themselves are still kept in a certain range of pond water. This results in a large amount of feces excreted by the slimming fish and fish food left over from feeding, as well as impurities or attachments formed by some solid substances such as silt. Excessive accumulation of impurities is not conducive to the growth of fish. In addition, the impurities contain a large amount of organic matter, which is oxidized and decomposed under the action of microorganisms, continuously consuming a large amount of dissolved oxygen in the water, which will increase the "oxygen debt" of the pond.

At present, dredging the pond wall usually requires draining the pond water and manually scraping and cleaning, which is not only time-consuming and labor-intensive, but also affects the breeding environment of the slimming fish, thereby affecting the normal growth of the slimming fish.

Detailed ways

The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

Please refer to Figure 1. This embodiment provides a slim fish breeding device, including a breeding box 1, a purification component 8, a return water pool 3 and a power component. The purification component 8 transports the purified water in the breeding box 1 to the return water pool 3, and the return water pool 3 then transports the purified water to the breeding box 1 to achieve water circulation and ensure the normal growth of the slim fish in the breeding box 1. A dredging component for scraping off attachments is provided in the breeding box 1. Driven by the power component, the dredging component cleans the attachments, and then the attachments enter the purification component 8 with the water for filtration and purification, thereby cleaning the attachments. Compared with the existing manual dredging, the entire dredging process does not require the capture of slim fish, thereby ensuring the normal growth of slim fish and saving manpower and time.

Please refer to Figures 1 to 3. A breeding pool 6 is provided inside the breeding box 1. The bottom of the breeding pool 6 is integrally formed with the bottom of the breeding box 1, and there is a gap between the breeding pool 6 and the side wall of the breeding box 1, thereby forming an annular buffer chamber 7. The side wall of the breeding pool 6 is provided with a plurality of connecting holes 5. The two ends of the connecting holes 5 are respectively connected to the breeding pool 6 and the buffer chamber 7. At the same time, the buffer chamber 7 is also connected to the return water pool 3. The water in the return water pool 3 enters the buffer chamber 7 and then flows into the breeding pool 6 from the connecting holes 5, so as to avoid the water in the return water pool 3 impacting the breeding pool 6 and causing an overreaction of the fish school, and also to avoid the water in the return water pool 3 excessively stirring the breeding pool 6 and causing incomplete cleaning of the attachments.

In this embodiment, the connecting hole 5 is provided with a first filter screen to prevent impurities from entering the breeding pool 6 along with the water flow; the connecting hole 5 is inclined, and the inclination direction is downward from the buffer chamber 7 to the breeding pool 6.

The bottom of the breeding pond 6 is conical, and a ring-shaped water pumping trough is arranged at the center thereof. A second filter is arranged on the top of the water pumping trough, and the mesh of the second filter is determined by the attachments passing through. After the dredging component cleans the attachments at the bottom of the breeding pond 6, it is convenient to enter the water pumping trough through the conical side wall, so that the attachments can be cleaned more thoroughly.

The desilting assembly includes a rotating disc and a scraper 2. The desilting disc is located inside the water pumping trough and is rotatably matched with the bottom of the culture pool 6. A toothed ring 16 is provided at the bottom of the rotating disc. There are 4 scraper rods 2, which are evenly arranged on the outside of the rotating disc. One end of the scraper rod 2 is fixedly connected to the rotating disc, and the other end of the scraper rod 2 extends to the side wall of the culture pool 6. The scraper rod 2 fits the bottom wall of the culture pool 6. When the toothed ring 16 drives the rotating disc to rotate, the scraper rod 2 rotates accordingly, thereby scraping off the attachments on the bottom wall of the culture pool 6. The attachments enter the water pumping trough under the action of water flow and gravity, and finally enter the purification assembly 8 to be cleaned.

In other embodiments of the present invention, the number of the scraper rods 2 may be 1, 2, 3, 5, etc.

In this embodiment, an ultrasonic transducer 12 is provided on one of the scraper rods 2, and the ultrasonic transducer 12 is connected to a float 11 through a connecting rope 15. After the ultrasonic transducer 12 emits ultrasound, it will drive the fish school to swim around the breeding pond, which can effectively improve the efficiency of slim fish breeding and reduce the fat of the slim fish itself. The existence of the float 11 makes it easy to know the position of the ultrasonic transducer 12, and it is convenient to replace and repair the ultrasonic transducer 12.

The power assembly includes a bracket, a waterwheel 4, a second gear rod 13 and a first gear rod 10. The bracket is fixedly mounted on the return pool 3, the wheel 401 of the waterwheel 4 is mounted on the bracket through a rotating shaft, a toothed disc 14 is connected to the rotating shaft, a water collecting trough 402 is provided on the wheel rim of the waterwheel 4, the second gear rod 13 is vertically arranged, and gears are respectively arranged at both ends, and the middle part thereof rotates with the bracket, and the first gear rod 10 is horizontally arranged, and gears are respectively arranged at both ends, and the middle part thereof rotates with the breeding box 1. The gear at the top of the second gear rod 13 meshes with the toothed disc 14, the gear at the bottom of the second gear rod 13 meshes with the gear at one end of the first gear rod 10, and the gear at the other end of the first gear rod 10 meshes with the gear ring 16.

The water flowing back from the purification assembly 8 impacts the water collecting tank 402, causing the water wheel 4 to rotate under the action of the eccentric force, thereby driving the gear ring 16 to rotate, and finally driving the scraper rod 2 to rotate.

The purification assembly 8 includes a sedimentation tank 801, an aeration tank 802 and a biological purification tank 803. The sedimentation tank 801 is connected to the pumping tank and the aeration tank 802 through the drainage assembly 9, respectively. The biological purification tank 803 is connected to the aeration tank 802 and the return water tank 3 through the drainage assembly 9, respectively. The return water tank 3 is also connected to the buffer chamber 7 through the drainage assembly 9.

In order to improve the purification efficiency of the purification component 8, flocculants can be added to the sedimentation tank 801 to increase the precipitation effect of solid impurities, and microecological preparations can be injected into the aeration tank 802. The water purified by the purification component 8 in the return water tank 3 must have a non-ionic ammonia content of less than 0.2 mg/L, a nitrite content of less than 0.2 mg/L, a pH of 6.5-8.0, and a water transparency of 40-50 cm.

The drainage assembly 9 includes a pump 901 and a conduit 902 which are connected to each other. The water body is circulated by the pump 901. The pump 901 can be installed in the upper structure or in the lower structure. Taking the connection between the buffer chamber 7 and the sedimentation tank 801 as an example, the pump 901 can be installed in the buffer chamber 7 or in the sedimentation tank 801, but it is best that the pump 901 is connected to the water inlet of the conduit 902.

In order to enable the waterwheel to rotate, in this embodiment, the outlet of the drainage assembly 9 between the biological purification tank 803 and the return tank 3 is located obliquely above the waterwheel 4, so that water can impact the waterwheel 4 and enable the waterwheel 4 to rotate continuously in one direction.
