Specific embodiment
The present invention is specifically described with reference to the accompanying drawing, as shown in figures 1 to 6, in the present embodiment:
It removes contamination on vehicle firstly, sewage collecting tank 1 is installed to, when needing to take out dirty sewage, dirty hose 25 will be taken out and be inserted into
It in sewer pipe, enters anti-clogging sewage pipe device in the sewage in sewer pipe, vacuum is controlled by controller 2 at this time
It takes out dirty pump 23 to start to work, vacuum takes out dirty pump 23 and starts to extract sewage by taking out dirty hose 25, and sewage passes through filtering sieve plate 30
By bulk contaminant filter in sewage, sewage enters in the dirty short tube 29 of pumping primary filtration, enters back into nipple 27, due to short
The diameter of adapter tube 27 becomes smaller, and the flow velocity of sewage is made to become faster, and when sewage passes through nipple 27, sewage washes away spiral fan 36, makes spiral shell
Rotation flabellum 36 starts to rotate, and the rotation of spiral fan 36 drives rotating blade 33 to start to rotate by small shaft 32, rotating blade 33
The impurity for filtering 30 lower section of sieve plate is smashed in rotation, while the impurity such as polybag being blown off, prevents impurity blocking filtering sieve plate 30,
Sewage is taken out dirty pump 23 by vacuum and is extracted, and is entered in sewage collecting tank 1 by outlet pipe 24, is carried out in sewage collecting tank 1
Storage；
When the sewage collecting in sewage collecting tank 1 to a certain extent after, staff observes dirt by plate type level meter 39
Sewage quantity in water collecting tank 1, when reaching the storage upper limit, control 2 control device of controller is out of service, can pass through at this time
Sewage collecting tank 1 is transported to discharge sites by vehicle of removing contamination；
When sewage collecting tank 1 is transported to discharge sites, water inlet pipe is connect with external water source pipeline at this time, controller 2
It controls rotating electric machine 15 to start to work, the rotation of rotating electric machine 15 drives driving gear 14 to rotate, and driving gear 14 drives internal gear
Slot guide rail 13 rotates, so that rotary shaft 4 be driven to start to rotate, the rotation of rotary shaft 4 drives helical flight 10 to start by support rod 7
It being rotated inside sewage collecting tank 1, the sludge precipitated on sewage collecting tank inner surface is wiped in the rotation of helical flight 10 off,
Sludge is scraped on sewage pipe 40 by the rotation of helical flight 10 simultaneously, by opening sewage draining valve 41, by sewage and sludge
It is externally discharged；
After sewage discharge, controller 2 controls suction pump 21 and starts to work at this time, and suction pump 21 pumps external water
It into water tank 18, is entered in the through-hole 28 in support rod 7 by the through-hole 1 in rotary shaft 4, then by support rod 7
Apopore 29 is sprayed onto sewage collecting tank 1, while controller 2 controls rotating electric machine 15 and works, and helical flight 10 passes through rotation
Cooperation clear water is cleaned, to carry out cleaning sullage collecting tank 1.
, using the flow velocity of sewage, drive sewage while taking out dirty 23 extraction sewage of pump by vacuum by aforesaid operations
Spiral fan 36 rotates, so that rotating blade 33 be driven to rotate, removes the impurity of 30 lower section of filtering sieve plate, facilitates device to take out dirty,
Simultaneously by the way that through-hole and apopore are arranged in rotary shaft 4 and support rod 7, to enable devices to be rapidly performed by cleaning, prevent
Only the sludge in sewage collecting tank 1 breeds bacterium, while can save again artificial.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
The principle of the present invention is embodied to some variations that some of them part may be made, belongs to the scope of protection of the present invention it
It is interior.
