Description
Technical field
The present invention relates to water-treatment technology field is and in particular to a kind of aquaculture water treatment device.
Background technology
The cultivation commonly used at present mainly carries out filtration treatment using two kinds of filter plants with recirculated water, and one kind is that cylinder declines
Filter, it includes one end open, the cylinder of another end closure, wraps the periphery at cylinder opening end, cylinder sides using filter screen
Have circular hole, cylinder is horizontally placed in water, make circular hole be located at cylinder topmost, and make water logging not have the half of cylinder, in cylinder
The water surface at the groove that connects with cylindrical outer of horizontally set；During work, cultivation water is poured into by circular hole, and flows out through screen pack,
After dirt is stayed in cylinder, drive cylinder rotation by driving means, dirt is taken away the water surface, then in cylinder external application high pressure
Water rinses, and dirt is rinsed in the groove with upstream face for the water, and flushing water flows automatically discharge together with dirt.The knot of this drum type brake Microfilter
Structure is complicated, cost is high, and its installed capacity is 1KW, high energy consumption, and dirt cannot remove totally, residual all the time in the water in cylinder
Leave most of dirt it is impossible to timely discharge, water quality during dirt persistent accumulation, can be deteriorated.Another kind is sieve bend, that is, rectangular
One curved screen is arranged on shape pond, cultivation water flows out from screen cloth bottom after passing through screen cloth, and dirt is then with fraction water
Stream is discharged；This curved screen can also be designed to track structure, dirt is taken away by the water surface by caterpillar curved screen,
Then by backwash, dirt is discharged.This sieve bend is susceptible to block in the course of the work, makes screen cloth be susceptible to corrode.
Content of the invention
It is an object of the invention to provide a kind of aquaculture water treatment device, its water treatment efficiency is high, and structure is simple, become

As shown in Figures 1 to 4, the aquaculture water treatment device of the present embodiment includes pond 100, filter assemblies 200, backwash group
Part 300 and drive component 400, the upper end in described pond 100 is provided with water inlet pipe 110, and described pond 100 sets adjacent to its bottom
It is equipped with outlet pipe 120；Described filter assemblies 200 include sieves 210, and described sieves 210 is adjacent to the upper end in described pond 100
Arrange and be located at below the mouth of pipe of described water inlet pipe 110, described backwash assembly 300 is in order to backwash described sieves 210；Institute
State drive component 400 to be connected with described filter assemblies 200, in order to selectively to control the sieves 210 of described filter assemblies 200 to revolve
Go to outside described pond 100.When needing to carry out backwashed screen 210, drive component 400 control sieves 210 rotate to
Outside pond 100, the backwashing water producing is backwashed with convenient use sieves 210 is backwashed, will filter in assembly 300
On sieve 210, the wash dirt of retention is to outside pond 100, it is to avoid dirt produces pollution to water after filtering in pond 100, and
Along the opposite direction filtering, sieves 210 is rinsed, cleaning intensity can be increased it is ensured that cleaning effect；When recoil washes it
Afterwards, then by drive component 400 drive sieves 210 to reset, continue cultivation water is filtered.The present embodiment passes through using drive
Dynamic assembly 400 selectively drives sieves 210 to rotate to the position of convenient backwash, improves cultivation water treatment efficiency and filtration
The quality of water.
Compared with prior art, the water treatment efficiency of the aquaculture water treatment device of the present embodiment is high, and structure is simple, becomes
This is low.
In the present embodiment, sieves 210 is always positioned at the top of the water surface in pond 100, to avoid sieves 210 to retain
Dirt be immersed in water and occur to deteriorate and filter water is produced with further pollution.
The aquaculture water treatment device of the present embodiment is applied to the aquacultures such as fish, shrimp, can improve the survival rate of aquatic products, fall
Low aquaculture cost.
The water outlet of the outlet pipe 120 in the present embodiment can be recycled to water inlet pipe 110, then is filtered by sieves 210, with
It is circulated use, great lot of water resources can be saved, to reduce the production cost of aquaculture.
In the present embodiment, the flexible pipe that described backwash assembly 300 is included shower nozzle 310 and connected with described shower nozzle 310
320, described shower nozzle 310 is connected with described filter assemblies 300 by connector, and is arranged at the lower section of described sieves 210.This
Shower nozzle 310 is arranged at the lower section of sieves 210 by embodiment, and shower nozzle 310 is connected with filter assemblies 200, and drive component 400 drives
During sieves 210 rotation, shower nozzle 310 can be made to rotate with, need not be by manually carrying out backwash operation；During using hard tube,
The rotation of sieves 210 and shower nozzle 310 can be restricted, and certainly will need to increase the energy consumption of drive component 400, the present embodiment is adopted
Being used as the water pipe connecting with shower nozzle 310 with flexible pipe 320, sieves 210 and the rotation of shower nozzle 310 being facilitated, thus reducing

412, by the motion of the stretching motion controls connecting rod 420 of piston rod 412.More specifically, being arranged at intervals with first outside pond 100
Mounting seat and the second mounting seat, body 411 is arranged in the first mounting seat by first rotating shaft 431, and first connecting rod 421 passes through the
Two rotating shafts 432 are arranged in the second mounting seat, and wherein, the level height of the second rotating shaft 432 is higher than the level height of first rotating shaft 431
Degree, and the upper end setting of the second rotating shaft 432 adjacent pool 100, during telescoping cylinder 410 work, telescoping cylinder 410 is in first connecting rod 421
In the presence of rotate along the axis of first rotating shaft 431, drive second connecting rod 422, third connecting rod 423 is respectively with the 3rd rotating shaft simultaneously
433rd, the axis of the 4th rotating shaft 434 is rotated for axle, thus driving filter assemblies 200 to rotate.Wherein, the 3rd rotating shaft 433 with
And the 4th rotating shaft 434 be on-fixed structure, also can move therewith in the presence of telescoping cylinder 410 and first connecting rod 421.
Specifically, described filter assemblies 200 include support 220 and the described sieves being installed on described support 220
210, described support 220 is connected with described third connecting rod 423 by fixture 230 so that described third connecting rod 423 drive described
Support 220 rotates.Third connecting rod 423 is fixedly connected with support 220 by fixture 230 away from one end of the 4th rotating shaft 434, mistake
Screen 210 is fixedly installed on support 220, to drive fixture 230 and support 220, sieves 210 by drive component 400
Rotate simultaneously.After being rotated in place, by backwashing assembly 300, sieves 210 is backwashed.
Specifically, described support 220 or described fixture 230 are provided with touching bar, under rotating along described touching bar
Roam all around the would controls the travel switch of described backwash assembly 300 operation to being provided with；When described drive component 400 drives described support
220 turn to set angle so that when sieves 210 reaches backwash position, described touching bar presses described travel switch,
So that the magnetic valve 330 in backwash assembly 300 is opened, backwashing water is switched on, and is sprayed onto sieves 210 by shower nozzle 310
On backwashed, when rinse after the completion of, drive component 400 control sieves 210 reset continue cultivation water is carried out at filtration
Reason.In the cultivation water filtration of the present embodiment and sieves 210, the backwash of dirt is automation process, makes cultivation water process real
Show intelligentized control method.
Wherein, described set angle is 110 °～135 °, preferably 120 °, after sieves 210 rotates 120 °, both conveniently enters
Row backwash operation, can reduce the energy consumption of drive component 400 again.
