The mode of operation of the scavenge unit of solid particulate matter in the aquaculture system water of the present invention is described in detail in detail below:
As shown in Figure 1, in normal operating conditions, rotary drum 30 is being with filter screen 32 static.Pending breed draining (containing solid particulate matter) is imported the water inlet pipes 20 from water delivery end 21, and is flowed in the rotary drums 30 by a plurality of perforates 23.Culture draining before flowing out rotary drum 30, must be through being arranged at the filter screen 32 of rotary drum 30 side faces, in the filter screen 32 filtering water with filter corresponding various solid particles of mesh number and suspension.
Device of the present invention is when filtering work normally, and rotary drum 30 is in still-mode, has therefore largely avoided the collision of big solid particulate matter and filter screen 32, and friction is sheared.Because after if these solid particulate matters frequent rub with filter screen 32, shear, collision etc. acts on, very fast disintegration is broken into finely ground particles, these finely ground particles just may pass the mesh on the filter screen 32 and get back in the circulatory system with current, another part of above-mentioned finely ground particles also may fill out knot and stop up mesh, the filter effect that has influenced.
After using a period of time, the big solid particulate matter that is filtered, suspensions etc. stop up the mesh on the filter screen 32 gradually.At this moment, the water level in the rotary drum 30 can rise gradually, and the submergence of rotary drum 30 progressively reaches 55-60%.Need do a cleaning this moment to filter screen 32, is called " backwash " in the industry.
As shown in Figures 2 and 3, derive a small amount of gas from blast aeration system, the air feed end 41 by air supply pipe 40 is input in the casing 10.Gas is discharged by outlet side 42 along air supply pipe 40.Because outlet side 42 is corresponding with the position of bucket type actuator 31, gas formed rising bubble in water can accumulate in the top of actuator 31.The buoyancy of these bubbles upwards promotes actuator 31.
Simultaneously, by the water inlet end 81 input tape setting-out of high-pressure hydraulic pump, the band setting-out is sprayed from nozzle 82 to backwash water pipe 80.Because nozzle 82 is towards connecing dirty part 50, the water that nozzle 82 is sprayed shoots down the particle that stops up filter screen 32 from filter screen 32, and these particles fall into the dirty part 50 that connects that is arranged in the below with water, and slide to the bottom that connects dirty part 50.Then, these particles are discharged by blow-off pipe 51.
After filter screen 32 is rinsed totally, stop to air supply pipe 40 air feed, also stop simultaneously to backwash water pipe 80 input water.
In whole backwash process, device of the present invention is in rotary state always.
In the process of cleaning filter screen 32, the gas output of control outlet side 42 just can be controlled the rotating speed of rotary drum 30.Said structure of the present invention can be realized stepless speed regulation according to Microfilter specification and operating mode needs.
In concrete enforcement, rotary drum 30 per minutes rotation 4 is changeed.Backwash water pipe 80 can wash away once at interval to filter screen 32 in 15 to 30 minutes, and each flushing time is 40-80 second.
Also can comprise a level sensor (not shown) in the present embodiment, be arranged at the inboard of casing 10, the altitude range of its setting is preferably the height of the submergence 55-60% of rotary drum 30.
The mesh of filter screen 32 in use can be stopped up by particle gradually.Along with the increase gradually of blocked area, the water level in the filter screen 32 rises gradually.When height of water level reached the position of level sensor, sensor just sent and starts the instruction that backwash is washed, in air supply pipe 40 input gas simultaneously by high-pressure hydraulic pump to backwash water pipe 80 input tape setting-out, with flushing filter screen 32.
Simultaneously, this instruction can also start the blowdown magnetic valve, opens blow-off pipe 51 and carries out blowdown, and the time can be 40～80 seconds.
The factory of breeding fish all disposes blast aeration system, all leaves surplus, the back pressure of the set air supply pipe 40 of scavenge unit of the present invention when selecting blower fan slightly, all in the blast scope of institute's configuration blower fan, and compole is short during with gas, and air consumption is atomic, can be to not breeding fish and the water treatment system aeration need exert an influence.Install and use this device, only need dispose one section airduct and get final product with the blast aeration system connection nearby.
Compared with prior art, scavenge unit of the present invention has saved the motor deceleration device of the heaviness that conventional Microfilter must use, and the drive unit air consumption that adopts is few, make device of the present invention have simple in structure, in light weight, cost is low, almost do not have mechanical vibrations and noise, easy maintenance, help increasing the service life, and realize the purpose of power saving, water-saving.In addition, static during the rotary drum operate as normal of the present invention's employing, submergence is big, has improved the removal efficient of scavenge unit.
