With reference to the accompanying drawings and detailed description the present invention is done with further details of theory
Bright.As shown in Figure 1, 2, originally exempt from backwash automatic pollution discharge modified model sand filtration cylinder, including cylinder
Body 1, cylinder body 1 top is provided with outlet 11, and cylinder body 1 top seal, in the middle part of cylinder body 1
It is provided with water inlet 12, be provided with cylinder body 1 and can float between outlet 11 and water inlet 12
Floated filter mechanism 2, cylinder body 1 bottom is provided with dirt collection sedimentation pipe 3, dirt collection sedimentation pipe
3 upper ends are connected with cylinder body 1 by removable structure, water inlet 12 and dirt collection sedimentation pipe 3 it
Between be provided with can make sewage through eddy flow water inlet deposition to dirt collection sedimentation pipe 3 vortex centrifugal machine
Structure 4, the discharge end of dirt collection sedimentation pipe 3 is provided with blowoff valve 31.
Cylinder body 1 includes cylindrical upper box 1a, upper box 1a lower end with up big and down small
Cone lower box 1b be connected, vortex centrifugal mechanism 4 is arranged in lower box 1b, collection
Dirty sedimentation pipe 3 is arranged on the bottom of lower box 1b, and flange arrangement is passed through in dirt collection sedimentation pipe 3 upper end
It is connected with lower box 1b.Vortex centrifugal mechanism 4 includes in up big and down small helical form and can
Make the plumbing for waste water 41 through eddy flow water inlet deposition to dirt collection sedimentation pipe 3 for the sewage, plumbing for waste water 41 passes through
Fixed mount is connected with lower box 1b, and the import of plumbing for waste water 41 vertically upward or tilt upward, is entered
The outlet of dirty pipe 41 is located at dirt collection sedimentation pipe 3 upper end and vertically down or tilt down.In order to
Improve dirt collection effect further, the import of plumbing for waste water 41 is set to toroidal.Additionally, entering
The outlet of dirty pipe 41 is set to toroidal, and this structure advantageously reduces going out of plumbing for waste water 41
The pressure of mouthful ejection, thus avoid in dirt collection sedimentation pipe 3 dirt by compression shock
Kick up again.The outlet of plumbing for waste water 41 also can be docked with dirt collection sedimentation pipe 3 upper end.
Floated filter mechanism 2 includes some floating pearls 21 and floating pearl 21 forms filter layer,
Floating pearl 21 can float between water inlet 12 and outlet 11.As shown in Fig. 2 water inlet
12 axis deviates from the axis of cylinder body 1 so that current tilt from water inlet 12
Enter in cylinder body 1 and form vortex.This water intake mode can make within entrance cylinder body 1
Water automatically forms vortex, is beneficial to dirt.The vortex that vortex centrifugal mechanism 4 is formed
The vortex direction that direction is formed with water inlet 12 is identical or contrary.Blowoff valve 31 is automatically controlled
Valve, water inlet 12 is inserted with water inlet pipe 121, and outlet 11 is inserted with outlet pipe 111；Dirt collection
The lower end of sedimentation pipe 3 is connected with floor drain adapter 3a；Upper box 1a is sealed by top cover at top
Close, top cover is connected with upper box 1a by removable structure, removable structure such as flange arrangement,
It is provided with sealing ring between top cover and upper box 1a.It is additionally provided with dirt collection sedimentation pipe 3 upper end

It is additionally provided with the detector that can detect dirt storage, dirt collection sedimentation pipe in dirt collection sedimentation pipe 3
3 are made of clear material.
During work, the water containing dirt is entered in cylinder body 1 by water inlet pipe 121 and is formed
Vortex.The larger dirt of granule settles downwards and from vortex in moving process with vortex
The import of centrifugal mechanism 4 (i.e. plumbing for waste water 41) enters, then from centrifugal mechanism 4 (i.e.
Plumbing for waste water 41) outlet discharge, consequently facilitating dirt enter dirt collection sedimentation pipe 3.Granule
Less dirt rises and is filtered by floated filter mechanism 2, and the water after filtering
Discharge from outlet 11.In filter process, the less debris accumulation of granule becomes larger
Dirt, settles in the presence of vortex, and from vortex centrifugal mechanism 4 in moving process
The import of (i.e. plumbing for waste water 41) enters, then from centrifugal mechanism 4 (i.e. plumbing for waste water 41)
Outlet exclusion, consequently facilitating dirt enter dirt collection sedimentation pipe 3.Therefore, cleaned
Cheng Zhong, dirt can effectively be collected in time.The dirt entering dirt collection sedimentation pipe 3 leads to
Crossing blowoff valve 31 and control intermittent discharge, thus realizing the timely discharge of dirt, need not shut down
And backwash.
Specific embodiment described herein is only theory for example to present invention spirit
Bright.Those skilled in the art can be to described specific embodiment
Make various modifications or supplement or substituted using similar mode, but without departing from
The spirit of the present invention or surmount scope defined in appended claims.
Although more employing cylinder body 1, outlet 11, water inlet 12 herein, suspending
Formula filter mechanism 2, dirt collection sedimentation pipe 3, blowoff valve 31, vortex centrifugal mechanism 4, top box
Body 1a, lower box 1b, plumbing for waste water 41, floating pearl 21, water inlet pipe 121, outlet pipe 111,
The terms such as floor drain adapter 3a, but it is not precluded from the probability using other terms.Using this
A little terms are used for the purpose of more easily describing and explaining the essence of the present invention；They are solved
It is all contrary with spirit of the present invention for being interpreted into any additional restriction.
