Embodiment 1

[0063] Self-cleaning internal circulation temperature-controlled breeding system, such as image 3 As shown, it includes an equipment rack 1 with a multi-layer frame structure inside, and the bottom layer of the equipment rack 1 is provided with a primary filter tank 2, a fine filter tank 4, and a water pump 6 connected in sequence; wherein the primary filter tank 2 and the fine filter tank The filter water tanks 4 can be connected through a dedicated water tank connecting pipe 3 , and the fine filter water tank 4 and the water pump 6 can be connected through a dedicated water pump connecting pipe 5 .

[0064] The fine filter water tank 4 is provided with a heating rod 4d capable of temperature control and adjustment, an ultraviolet sterilizer 7 is provided at the water outlet of the water pump 6, a water supply main pipe 8 is provided on one side of the equipment rack 1, and the water supply main pipe 8 runs along the equipment rack 1 The height direction extends from bottom ...

Embodiment 2

[0070] Such as Figure 4-Figure 6 As shown, a filter disc 2a is provided in the primary filtration tank 2, and the filter disc 2a is arranged at the notch position of the primary filtration tank 2, and a pre-filter 2b is arranged in the filter disc 2a, and the circulating water flowing back into the pre-filter tank enters the primary filter When the water tank 2 falls into the filter disc 2a earlier, the pre-filter 2b in the filter disc 2a can filter out larger impurities such as cultured biological excrement and food residues in the circulating water.

[0071] A bioreactor 2c is provided below the filter disc 2a, and a plurality of biological nitrification reaction balls are arranged in the bioreactor 2c, and the circulating water passing through the filter disc 2a falls into the bioreactor 2c, and the bioreactor 2c performs high-efficiency on the circulating water. Ammonia removal biological treatment. The bottom of the bioreactor 2c is provided with a support frame 2d, the...

Embodiment 3

[0077] Such as Figure 8-Figure 10 As shown, the diversion valve 15 used in this system is made of stainless steel, including a valve body 15a and a valve core 15b, the two are socketed, the lower part of the valve body 15a is provided with a water inlet 15c, and the upper part of the valve core 15b is provided with an overflow The mouth 15d is provided with a sealing ring groove 15e at the bottom, and a sealing ring is built in it. When the breeding tank 13 stops replenishing water, the sealing ring can play a sealing role to prevent the breeding tank 13 from leaking through the bottom of the valve core 15b. When the replenishment water level in the breeding tank 13 exceeds the overflow port 15d on the valve core 15b, the diversion valve 15 forms a connector, and water will enter the diversion valve 15 through the water inlet 15c at the bottom of the valve body 15a, and pass through the valve core 15b top The overflow port 15d flows into the internal cavity of the spool 15b ...

Abstract

The invention discloses a self-cleaning internal-circulation temperature-control type culture system. The system comprises an equipment rack, wherein a preliminary filter water tank, a fine filter water tank and a water pump which communicate with one another sequentially are arranged at the bottom layer of the equipment rack; a heating rod is arranged in the fine filter water tank, an ultraviolet disinfector is arranged at a water outlet end of the water pump, a water supply main pipe is arranged at one side of the equipment rack, a plurality of culture jars are arranged on a layered frame of each layer, a dustproof cover plate is arranged on each culture jar, a water supply branch pipe is arranged on a top wall of a space where the layered frame of each layer is located, the upwards-extending water supply main pipe communicates with the water supply branch pipe of each layer, and the lower end of the water supply main pipe communicates with the water pump through the ultraviolet disinfector; a culture jar water supply pipe is arranged above each culture jar, one end of each culture jar water supply pipe communicates with the corresponding water supply branch pipe, the other end of each culture jar water supply pipe penetrates through a water replenishing port in the corresponding cover plate and extends into the corresponding culture jar; and waste collecting tanks are arranged on the layered frames and communicate with the culture jars, wastes in the culture jars flow in the waste collecting tanks together with refluxing wastewater, and a waste discharging pipe is arranged at the other side of the equipment rack and communicates with the waste collecting tanks so as to enable the refluxing wastewater to reflux into the preliminary filter water tank.

Description

technical field [0001] The invention belongs to the field of breeding system equipment, and in particular relates to a self-cleaning internal circulation temperature-controlling breeding system. Background technique [0002] Zebrafish (commonly known as Zebra fish) is widely used in modern life science research because of its strong reproductive ability, in vitro fertilization and development, transparent embryo, short sexual maturity cycle, and small individual. The breeding of zebrafish for toxicological certification of drugs and environmental ecotoxicity testing requires strict control of the introduction of interference sources in the breeding system to ensure the absolute health of zebrafish test individuals and avoid test or certification test results caused by individual factors in the test. error. Therefore, it is imminent to develop such a zebrafish breeding equipment suitable for strict drug toxicology certification and environmental ecotoxicity testing. [0003...
