Abstract

The invention provides a protein separator for live fish transportation which is different from a traditional protein separator. The invention pumps waste water in a fish container and preprocessed cooling water into the separator body for confluence and mutual disturbance through two sets of ejectors connected in parallel (meanwhile, the ejectors inhale pure oxygen gas to fully blend with ejecting water flow according to the working principle of Venturi) and blend again with micro bubbles released from a dissolved oxygen aeration micropore pipe component, then rising turbulent water flow is generated after combined action. During the motor process of water flow from bottom to top, a large number of micro bubbles constantly coacervate with protein, fiber, suspended particle and jelly and the like in water body to become larger and larger and generate air floating effect, ensuring soiling in the water body to rise in the form of concentrated bubbles to the pipe and be outputted by a drainage tube, thus organic hazardous substances in the water body and the like are effectively separated and wiped out; meanwhile clean water separated from injurants such as protein and the like refluxes to the fish container through a effluent drainage tube which is connected with a drain pipe, thereby realizing the purpose of the invention.

Description

Protein skimmer for live fish transport

technical field

The present invention relates to a protein separator, in particular to a live fish transportation device that can be used in the field of fishery to carry out water quality treatment for the long-distance collection and transportation of commercial fish and juvenile fish fry in the way of car (or train) transportation. protein skimmer.

Background technique

Protein skimmer (skimmer), also known as protein skimmer, protein demister, protein remover, etc., is a simple and effective sewage treatment device that can be used to reduce suspended particles, colloids, Various organic matter such as water-soluble protein, it uses the principle of tension adsorption between air bubbles and water contact surface to gather and concentrate organic matter, and separates and removes suspended colloid, cellulose, and protein in aquaculture sewage by means of air flotation Organic matter such as vegetarian food, residual bait and feces.

In the sewage treatment of fish farming projects, the conventional chemical filtration method has been used for decades, and the method of foam decontamination has only appeared in recent years. Compared with conventional chemical filtration, it is more effective for protein to be decomposed Only skimmers can be removed most thoroughly. Therefore, protein skimmers are now being used more and more. The list of substances removed from protein skimmers includes protein, ammonia, copper and zinc and other metals, grease, carbohydrates, phosphate, iodine, fatty acids and phenol.

Protein skimmers are more used in aquarium life support systems and industrial fish farming systems. Up to now, their structural forms have been varied. Some use the principle of jets, and some use the method of air pumps. The above can be made into large and medium-sized protein skimmer. The latest models are small protein skimmers made with needle pumps or needle brush motors, most of which are used in aquarium systems.

It can be said that in the aquarium life support and breeding system of marine fish, the protein skimmer is an indispensable and important part of the circulating water treatment process. However, in freshwater fish aquarium life support or breeding systems, due to the lack of electrolytes in fresh water and the low surface tension of fresh water, it is difficult for general protein skimmers to condense and form concentrated "dirt foam" in the process of processing circulating water. Both are poor. Especially in the preservation system for long-distance collection and transportation of commercial fish and juvenile fish, due to poor objective conditions and many influencing factors, no vehicle protein skimmer with reliable water treatment function has been found in practical application so far.
