Description
Technical Field
The invention relates to a vertical-flow type micro-filter and a working method thereof, belonging to the technical field of filter equipment design.
Background
At present, the general filtering mode is that garbage and water are separated through a filter screen, or the garbage is settled through the difference of the weight of the garbage and the buoyancy force, so that the water and the garbage are separated, the filter screen has the advantage of high filtering efficiency, the defect is that the filter screen cannot cope with the garbage with various filter diameters, and a drum type micro-filter adopts large-particle garbage to repeatedly roll in a circular filter screen until the volume is reduced and the garbage is settled, or the garbage is decomposed to the position where the weight of particles is less than the sum of the buoyancy force and the adhesion force of the filter screen and the garbage can be brought to the backflushed position.
The existing filtering equipment has the problems of smaller filtering particle size range and lower filtering efficiency. The existing aquaculture particle garbage separation equipment is usually a rotary drum type micro-filter, a curved screen and a vertical flow type separator, and the equipment has advantages and disadvantages.
Prior art 1: the surface of the filter screen of the rotary drum type micro-filter is different in mesh size, garbage blocks the meshes under the action of water pressure to generate negative pressure, the garbage blocks the filter screen and is attached to the filter screen, the filter screen starts to rotate, the original filtering part in water rotates to be separated from the water surface, the top of the filter screen is backflushed by water, and the garbage enters the diversion trench to be discharged out of the micro-filter, so that one-time filtering backflushing is completed. The micro-filter meets the condition that the adhesion force of the garbage attached to the filter screen is larger than the gravity when the garbage leaves the water surface, otherwise, the garbage falls into the water again until the adhesion force is larger than the gravity, as shown in figure 1, but the gravity of large particles is larger than the adhesion force generally, so that the micro-filter can not filter out the aquaculture water body after the fatal short plate and the like of the micro-filter are decomposed. But the earlier the culture water body is taken out, the excrement water body is less polluted, so the technical requirement cannot be realized.
Prior art 2: the sieve bend, sieve bend are an arc or put the filter screen to one side, do not have water pressure, and water passes through from the upside of filter screen, because the action of gravity, the rivers down walk, and rubbish is filtered on the filter screen upper strata to realize filtering separation. The advantage of this filtration is that it is simple and fast and can filter large particles of waste, but if the mesh is too small for filtering fine waste, the screen will block too fast because no water pressure exists and the tail water will be drained directly without filtration, and the screen using this mode is usually a smaller mesh screen, as shown in fig. 2.
Prior art 3: the vertical flow type garbage diverter is a device for realizing separation by utilizing the difference between the gravity and the water buoyancy of garbage, and under the condition of continuous water inlet and water outlet, most of the gravity is close to the buoyancy, even part of the garbage with the gravity larger than the buoyancy is circulated back to the aquaculture water body under the action of water flow impact force, as shown in figure 3.
Therefore, there is a need for a new type of high efficiency filtering equipment that combines the advantages of physical filtering with the main drum and sieve bend and the advantages of vertical separation of large specific gravity particulate waste.

8. The working method of the vertical-flow type microfilter according to claim 1, characterized by comprising the following steps:
the positive washing step specifically comprises the following steps: sewage enters the vertical flow separation bin (5) through the water inlet pipe (9) and flows out through the water outlet pipe (2), large-specific gravity particles in the sewage are settled and collected at the sewage outlet (10), small-specific gravity garbage in the sewage can be blocked by the filter screen (8) until the garbage in the vertical flow separation bin (5) is too much to influence the water level, and a back washing step is carried out;
the back washing step specifically comprises the following steps: blowoff valve (11) are opened, and inlet tube (9) are closed simultaneously, and the rivers direction through filter screen (8) takes place to reverse, and big or small granule rubbish is simultaneously through blow off pipe (6) discharge micro-filter organism (1), and when the position that the water level descends to blowdown water level inductor (4), blow off pipe (6) are closed, and inlet tube (9) are opened, and the loop filter begins again.
9. The working method of the vertical flow type micro-filter according to claim 8, wherein the positive washing step specifically comprises: inlet tube (9) are opened, sewage passes through inlet tube (9) and gets into vertical flow separation storehouse (5), and the big proportion granule in the sewage subsides and collects in drain (10), and little proportion rubbish in the sewage can be blocked by filter screen (8), and constantly at filter screen (8) accumulation, brush reciprocating motion mechanism (7) can be constantly reciprocal when little proportion rubbish accumulation area is constantly scrubbed, until vertical flow separation storehouse (5) rubbish is too much influences the water level, shift to the back flush step.
10. The working method of the vertical flow type micro-filter according to claim 8, wherein the back washing step comprises: water level inductor (3) form blowoff valve (11) of recoil signal control bottom and open, inlet tube (9) are closed simultaneously, the rivers direction through filter screen (8) this moment takes place to reverse, change to downwards by original upwards, big or small granule rubbish is simultaneously through blow off pipe (6) discharge micro-filtration organism (1), fall to the position of blowdown water level inductor (4) when the water level, blowdown water level inductor (4) send just wash blowoff valve (11) disconnection of signal control bottom, blow off pipe (6) are closed, inlet tube (9) are opened, circulating filtration restarts.
