Description

Technical Field

[0001] The utility model relates to the technical field of water treatment in industrialized recirculating aquaculture systems, and particularly relates to a biological purification system with adjustable gas-liquid balance in industrialized recirculating aquaculture. Background Technique

[0002] Industrialized recirculating aquaculture is a way of aquaculture using industrial production methods. Its working principle is to close and recycle the aquaculture water body, and purify and disinfect the aquaculture water body through physical, chemical and biological means to maintain the stability and cleanliness of the water quality.

[0003] In an industrialized recirculating high-density aquaculture system, the removal of ammonia nitrogen and nitrite by biological filters is very important. At present, due to problems such as land nature (cannot be hardened), construction costs, and maintainability, the construction of biological filters has gradually changed from the original concrete structure to movable PP barrels.

[0004] Although the biological purification barrels made of PP material have the advantages of low construction cost and strong operation and maintenance, there is also a major problem: that is, due to unreasonable pipeline design, or unreasonable pressure difference design, the biological purification system composed of multiple biological purification barrels is prone to gas-liquid imbalance, resulting in water overflow in the biological purification barrels and biological fillers running out, leading to poor treatment effects of ammonia nitrogen and nitrite, causing aquaculture losses, and therefore unable to meet people's needs.

[0005] In order to solve the above problems, the utility model provides a biological purification system with adjustable gas-liquid balance for industrialized recirculating aquaculture. Content of the Utility Model

Specific embodiments

[0020] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, any combination can be formed among the following-described embodiments or technical features to form a new embodiment.

[0021] Embodiment 1: Please refer to Figure 1 - Figure 2, A biological purification system for adjustable gas-liquid balance in industrialized recirculating aquaculture in this embodiment is applied to industrial aquaculture and includes: several groups of biological purification barrels 1 and a purification mechanism communicated with the biological purification barrels 1; wherein, biological fillers 2 are filled inside the biological purification barrels 1; the purification mechanism includes a clear water barrel 3 arranged on one side of the biological purification barrel 1, several groups of aeration discs 4 arranged at the inner bottom of the biological purification barrel 1, and a blower 5 arranged outside the biological purification barrel 1 and communicated with the aeration discs 4. The blower 5 and the aeration discs 4 cooperate to continuously tumble the biological fillers 2 and fully contact with the water body to remove toxic substances such as ammonia nitrogen and nitrite in the water body; an inlet pipe 6 and an outlet pipe 7 communicated with the clear water barrel 3 are arranged on the biological purification barrel 1, and the purified water body in the biological purification barrel 1 enters the clear water barrel 3 through the outlet pipe 7; an ultrasonic liquid level sensor 9 is detachably installed on the biological purification barrel 1, and the electric valve 8 and the ultrasonic liquid level sensor 9 are linked. The ultrasonic principle can be used to measure the liquid height inside the biological purification barrel 1. The inlet pipe 6 introduces water into the biological purification barrel 1, and the blower 5 is started to introduce gas into the aeration discs 4, so that the biological fillers 2 in the biological purification barrel 1 continuously tumble and fully contact with the water body to remove toxic substances such as ammonia nitrogen and nitrite in the water body, thereby purifying the water body, and the purified water body enters the clear water barrel 3 through the outlet pipe 7 of the biological purification barrel 1 respectively. The ultrasonic liquid level sensor 9 is started to monitor the water body inside the biological purification barrel 1. When the ultrasonic liquid level sensor 9 in the biological purification barrel 1 with a high water level detects a high water level, a signal will be transmitted to the control cabinet 10, and the control cabinet 10 will control the electric valve 8 on the inlet pipe 6 to close slightly, and the water body will enter the biological purification barrel 1 with a lower liquid level more. After such multiple operations, the liquid level heights in multiple biological purification barrels 1 will be the same. In this way, the resistance of the gas in the blower 5 entering multiple biological purification barrels 1 will be the same, thus solving the gas-liquid balance of multiple biological purification barrels and avoiding problems such as water overflow in the biological purification barrels and the running out of biological fillers.

[0022] A control cabinet 10 is arranged on one side of the biological purification barrel 1, and cables 11 respectively connected to the electric valve 8 and the ultrasonic liquid level sensor 9 are arranged on the control cabinet 10. The control cabinet 10 can control the opening and closing of the electric valve 8 and the ultrasonic liquid level sensor 9.

[0023] The purification mechanism further includes a circulating water pump 14 and a microfiltration machine pool 12 communicated with the circulating water pump 14. One end of the inlet pipe 6 is communicated with the circulating water pump 14. A water guide pipe 13 communicated with the microfiltration machine pool 12 is arranged on the circulating water pump 14. A microfiltration machine 16 is arranged on the microfiltration machine pool 12. The microfiltration machine pool 12 and the microfiltration machine 16 cooperate to be able to filter and remove large particles.

[0024] The height at which the outlet pipe 7 enters the clear water barrel 3 is 60 CM lower than the upper edge of the clear water barrel 3, so that the water body in the biological purification barrel 1 can flow into the clear water barrel 3 more smoothly.

[0025] An air duct 15 communicating with a blower 5 is provided on each aeration disc 4.

[0026] When the biological purification system capable of adjusting gas-liquid balance in industrialized recirculating aquaculture is in use, start the blower 5 to introduce gas into the aeration disc 4, so that the biological packing 2 in the biological purification barrel 1 continuously tumbles and makes full contact with the water body, removing toxic substances such as ammonia nitrogen and nitrite in the water body, thereby purifying the water body, and the purified water body enters the clear water barrel 3 through the water outlet pipe 7 of the biological purification barrel 1 respectively. Start the ultrasonic liquid level sensor 9, which can monitor the water body inside the biological purification barrel 1. When the ultrasonic liquid level sensor 9 in the biological purification barrel 1 with a high water level detects a high water level, it will transmit a signal to the control cabinet 10, and the control cabinet 10 will control the electric valve 8 on the water inlet pipe 6 to close slightly, and more water will enter the biological purification barrel 1 with a low liquid level. After such operations for many times, until the liquid level heights in multiple biological purification barrels 1 are the same.

[0027] In the prior art, due to the different volumes of multiple biological purification barrels 1, the amounts of biological packing filled inside are also different, and the amounts of biological packing film formation are also different, resulting in different amounts of biological film shedding. After a long time, coupled with the different sizes of the pipes entering the clear water barrel 3, the liquid level heights in multiple biological purification barrels 1 will be different. Due to the aeration of the blower 5, the gas will surely preferentially enter the biological purification barrel 1 with less resistance (that is, the biological purification barrel 1 with a low water level), so that the water level in the biological purification barrel 1 with a high water level will rise, causing the biological packing 4 to overflow with the water flow.

[0028] Through the ultrasonic liquid level sensors 9, water inlet pipes 6 and electric valves 8 on multiple biological purification barrels 1, and realizing linkage. When the ultrasonic liquid level sensor 9 in the biological purification barrel 1 with a high water level detects a high water level, it will transmit a signal to the control cabinet 10, and the control cabinet 10 will control the electric valve 8 on the water inlet pipe 6 to close slightly, and more water will enter the biological purification barrel 1 with a low liquid level. After such operations for many times, until the liquid level heights in multiple biological purification barrels 1 are the same. In this way, the resistance of the blower 5 entering multiple biological purification barrels 1 will be the same, thus solving the gas-liquid balance of multiple biological purification barrels.

[0029] The biological purification system capable of adjusting gas-liquid balance in industrialized recirculating aquaculture realizes parallel and separate entry into the clear water tank 3 through the provided biological purification barrel 1 and purification mechanism. The cooperation of the biological purification barrel 1, the clear water tank 3, the water inlet pipe 6 and the water outlet pipe 7 makes it easier to control the water volume and achieve dynamic balance compared with the original situation where the water outlets of multiple biological purification barrels 1 enter the clear water tank 3 through a series pipeline. By setting ultrasonic liquid level sensors 9, water inlet pipes 6 and electric valves 8 inside several groups of biological purification barrels 1 and realizing linkage, the gas-liquid balance of multiple biological purification barrels 1 is solved, and the problems of water overflow in the biological purification barrels 1 and the running out of biological fillers are avoided.

[0030] The above-mentioned implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the protection scope required by the present invention.
