During generator, the antibacterial in water, virus are killed, and decompose fish faeces and unnecessary fish grain rots the ammonia that produces and nitrous acid
Salt.This filtration-bacteria-except the continuous reciprocation cycle of process of algae-sterilization, thus having reached protection healthy fish and so that water is cleaned
Purpose.
The cleaning of this close filter and backwash process are as follows: constantly gather with the dirt in closed filter,
Between the water inlet of closed filter and water outlet, pressure reduction is formed, and constantly increases, and causes the water yield of filter to taper into, arrives
To a certain degree it is accomplished by closed filter is cleaned and backwash, to ensure cleaning and the water yield of water outlet.Pass through again
The air blast that high pressure air pump produces carries out to the filter material inside closed filter and dirt separating, and filter material and chamber wall divide
From then with water pump by outside the dirt exclusion filter being in free state.
The system is simple to operate: is provided with the electric-control system 4 of automatic timing function first, then by closed filter 6
Valve be placed in " filtration " position, open at the bottom of pond water sucking mouth, pond face water sucking mouth and water pump 4, pump outlet valve, start water pump
4, system carries out normal filtration cycle.As the big 1psi of closed filter manometric pressure ratio reset pressure, or pressure gauge
Pressure reduction be more than 1psi when, need closed filter to be cleaned and backwash.Cleaning and backwash process are as follows: adjustment
The on off state (concrete operations are: closed filter knob is rotated to backwash button) of each valve, starts high-pressure blast
Pump 5, after 1-2 minute, the dirt in closed filter is in free state, closes air pump；Then start water pump 4, by dirt
Discharge closed filter.This process can be repeated, until closed filter clean outlet.Whole operation process, saves time
Laborsaving, simple to operate, free and relaxed, convenient and swift.
In technical solutions of the utility model, circulating filtration water pump can be according to fishpond volume size, density of breeding fish, and filter is big
The quantity of little and filter matches the water pump of a suitable power, is used for circulating water in system worked well, when cleaning
During filter, for combining with high pressure air pump, backwash is carried out to filter, the dirt discharge filter that dissociates in filter needs
During emptying water, by main discharge outlet as water sucking mouth, water is drained, due to being equipped with high pressure air pump and combine, filter is carried out
Rinse, so without outfit high powered water pump, thus reducing energy consumption.
In technical solutions of the utility model, high pressure air pump in this system, can be according to the matter of the size of filter and filter material
Selecting the high pressure air pump of suitable power, it is mainly used in before water pump carries out backwash and cleaning to filter, leading to for ground and quantity
Cross gases at high pressure dirt in filter and filter material to be carried out separate, thus the dirt discharge filter that will dissociate.
In technical solutions of the utility model, this system has sealing function, have simultaneously circulating filtration, cleaning, backwash,
Draining, pressure such as show at the function, can select one or more water pump and mistake according to fishpond water capacity, density of breeding fish, feeding amount
Filter size and number.Species also dependent on fish is placed in similar and different filtrate in filter.
In technical solutions of the utility model, this system all using Closed Cycle equipment, has from water inlet to outlet
Good environmental protection, will not be to environment.Civil engineering is required low, floor space is little, and installation period is short, and operating expenses is low.
Due to having mechanical filter and biochemistry filtered dual-use function, therefore filter effect is powerful.
In this utility model, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection ", " Gu
Fixed " etc. term should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected or integral；Can be
It is mechanically connected or electrically connect；Can be to be joined directly together it is also possible to be indirectly connected to by intermediary, for example, pass through pipe
Road connects, and pipeline can also arrange the structures such as valve as the case may be, can be the connection of two element internals or two
The interaction relationship of element, limits unless otherwise clear and definite.For the ordinary skill in the art, can be according to tool
Body situation understands concrete meaning in this utility model for the above-mentioned term.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
