In figure, cylinder body 1, delivery port 11, water inlet 12, floated filter mechanism 2, collect dirty sedimentation pipe 3, blowoff valve 31, vortex centrifugal mechanism 4, upper box 1a, lower box 1b, plumbing for waste water 41, floating pearl 21, water inlet pipe 121, outlet pipe 111, floor drain adapter 3a.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.As Fig. 1, shown in 2, originally backwash automatic pollution discharge modified sand filtration cylinder is exempted from, comprise cylinder body 1, cylinder body 1 top is provided with delivery port 11, cylinder body 1 top seal, water inlet 12 is provided with in the middle part of cylinder body 1, the floated filter mechanism 2 that can float between delivery port 11 and water inlet 12 is provided with in cylinder body 1, the dirty sedimentation pipe 3 of collection is provided with bottom cylinder body 1, collect dirty sedimentation pipe 3 upper end to be connected with cylinder body 1 by removable structure, water inlet 12 and collect to be provided with between dirty sedimentation pipe 3 sewage can be made through eddy flow hydrostatic to be deposited into the vortex centrifugal mechanism 4 collecting dirty sedimentation pipe 3, the discharge end collecting dirty sedimentation pipe 3 is provided with blowoff valve 31.
Cylinder body 1 comprises upper box 1a cylindrically, upper box 1a lower end is connected with big up and small down conical lower box 1b, vortex centrifugal mechanism 4 is arranged in lower box 1b, collect the bottom that dirty sedimentation pipe 3 is arranged on lower box 1b, collect dirty sedimentation pipe 3 upper end and be connected with lower box 1b by flange arrangement.Vortex centrifugal mechanism 4 comprises big up and small down helical form and sewage can be made through eddy flow hydrostatic to be deposited into the plumbing for waste water 41 collecting dirty sedimentation pipe 3, plumbing for waste water 41 is connected with lower box 1b by fixed mount, vertically upward or tilt upward, the outlet of plumbing for waste water 41 is positioned at dirty sedimentation pipe 3 upper end of collection and vertically or tilt down down for the import of plumbing for waste water 41.In order to improve the dirty effect of collection further, the import of plumbing for waste water 41 is set to toroidal.In addition, the outlet of plumbing for waste water 41 is set to toroidal, and this structure is conducive to the pressure of outlet effluent reducing plumbing for waste water 41, thus avoids being arranged in dirty sedimentation pipe 3 dirt of collection and again kicked up by compression shock.The outlet of plumbing for waste water 41 also can be docked with dirty sedimentation pipe 3 upper end of collection.
Floated filter mechanism 2 comprises some floating pearls 21 and floating pearl 21 forms filter course, and floating pearl 21 can float between water inlet 12 and delivery port 11.As shown in Figure 2, the axis of water inlet 12 deviates from the axis of cylinder body 1 thus makes current tilt to enter in cylinder body 1 from water inlet 12 and form eddy current.This water intake mode can make the water entering cylinder body 1 inside automatically form eddy current, is beneficial to dirt.The eddy current direction that the eddy current direction that vortex centrifugal mechanism 4 is formed and water inlet 12 are formed is identical or contrary.Blowoff valve 31 is electrically-controlled valve, and water inlet 12 is inserted with water inlet pipe 121, and delivery port 11 is inserted with outlet pipe 111; The lower end collecting dirty sedimentation pipe 3 is connected with floor drain adapter 3a; Upper box 1a top is by top closure, and top cover is connected with upper box 1a by removable structure, and removable structure is flange arrangement such as, between top cover and upper box 1a, be provided with sealing ring.Also being provided with in dirty sedimentation pipe 3 upper end of collection to prevent dirt from entering the anti-flexible contaminants counterflow assembly flowed out from dirty sedimentation pipe 3 upper end of collection after in the dirty sedimentation pipe 3 of collection, water after this anti-flexible contaminants counterflow assembly allows prefiltration passes through, in the dirty sedimentation pipe 3 of collection, be also provided with the detector that can detect dirt storage, collect dirty sedimentation pipe 3 and be made up of transparent material.
During work, the water containing dirt to be entered in cylinder body 1 by water inlet pipe 121 and forms eddy current.The larger dirt of particle is along with the downward sedimentation of eddy current and enter from the import of vortex centrifugal mechanism 4 (i.e. plumbing for waste water 41) in moving process, then discharge from the outlet of centrifugal mechanism 4 (i.e. plumbing for waste water 41), thus be convenient to dirt enter collection dirty sedimentation pipe 3.The dirt that particle is less rises and is filtered by floated filter mechanism 2, and the water after filtering is discharged from delivery port 11.In filter process, the debris accumulation that particle is less becomes larger dirt, sedimentation under the effect of eddy current, and enter from the import of vortex centrifugal mechanism 4 (i.e. plumbing for waste water 41) in moving process, then get rid of from the outlet of centrifugal mechanism 4 (i.e. plumbing for waste water 41), thus be convenient to dirt enter collection dirty sedimentation pipe 3.Therefore, in purification process, dirt can effectively be collected in time.Enter the dirt collecting dirty sedimentation pipe 3 and control intermittent discharge by blowoff valve 31, thus realize the timely discharge of dirt, without the need to shutting down and backwash.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
Although more employ cylinder body 1, delivery port 11, water inlet 12, floated filter mechanism 2 herein, collect dirty sedimentation pipe 3, blowoff valve 31, vortex centrifugal mechanism 4, upper box 1a, lower box 1b, plumbing for waste water 41, the term such as floating pearl 21, water inlet pipe 121, outlet pipe 111, floor drain adapter 3a, do not get rid of the possibility of other term of use.These terms are used to be only used to describe and explain essence of the present invention more easily; The restriction that they are construed to any one additional is all contrary with spirit of the present invention.
