Background technology
The utility model patent of Application No. 201320633106.6 discloses a kind of suction-type sewer scavenger, it is the principle utilizing negative-pressure pneumatic to carry, powder body, solid, mud etc. are sucked in recycling can, there is the powerful captivation (suction height, horizontal range length, attraction speed are fast) exceeding well over conventional vacuum suction-type sewer scavenger, simple to operate, safeguard the features such as convenient, for the recovery that various mud, feces and dirt are husky.It goes for the suction of drift, shipment and the disposing of the mud in catch-basin, inspection shaft, sedimentation and various irrigation canals and ditches, septic tank contamination feces and cesspool, can also be used for shipping the liquid garbages such as refuse depot, garbage-compressing percolate and industry is harmful, and transport corresponding Treatment stations.
In the sewage of the sewer of suction-type sewer scavenger cleaning now, anaerobic tank, percolate storage pool etc., in addition to waste water and silt, possibly together with more thick slag (thing that hardens, branch, wooden unit, plastic bag (bottle), cloth, hygienic article, stone etc.), these thick slags are the main causes resulted in blockage.The main purpose of suction-type sewer scavenger cleaning is to be pumped out by thick slag, reduces blocking, allows sewer, anaerobic tank etc. give play to normal function.
This suction-type sewer scavenger passes through strong pumping, is mixed in water by thick slag together in suction tank.After being filled tank, it is transported to sewage treatment plant together and does subsequent treatment.It is then back to site clearing, carries out lower whorl circulation, until completing cleaning work.So having a problem in that
1. overall cleaning efficiency is low
Although pumping efficiency is high, but owing to tank volume is limited, the many slags of water are few, need to repeatedly aspirate, repeatedly transport, just can complete thick slag prune job, operation is discontinuous, transport elapsed time length (Sewage Plant distance is the most remote more prominent), causes overall cleaning efficiency to process low.
2. cost is high, increase traffic pressure and pollution
For completing prune job, needing repeatedly to transport, cost of transportation is high.Owing to transport to increase vehicle flowrate through urban road, the tail gas of motor vehicle emission produces the water clock brought because of seal failure with possible and shed, increasing environmental pollution.
3. increase the pressure of the pre-processing devices such as Sewage Plant coarse rack, affect Sewage Plant disposal ability.
