Sewage disposal, refers to make the water quality requirement that sewage reaches draining or reuses, and it is purified
Process.Sewage disposal is extensively using each with building, agricultural, traffic, the energy, petrochemical industry, environmental protection, urban landscape, medical treatment, food and drink etc.
Field.Sewage disposal mainly includes pretreatment and advanced treatment two procedures, and the particulate matter in sewage is mainly discharged in pretreatment
Matter, advanced treating are mainly aerated sewage, are aoxidized, being sterilized.
Traditional sewage disinfection treatment is filtered by filter screen, and this mode can cause the less dirt of particle diameter in sewage
Mud, suspended matter cannot be screened out, and cause the effect of filtering poor, and each time after filtering, it is necessary to filter screen be taken out, removing
After impurity, then filtering next time is carried out, cause the efficiency of filtering low.
The content of the invention
The invention is intended to provide a kind of sewage pre-treatment device, with solve impurity that the prior art can only be larger to particle into
Row cleaning so that the problem of less impurity of particle can remain in water.
To achieve the above object, the following technical solution of present invention offer, sewage pre-treatment device, including from left to right successively

Filter screen is equipped with passage；Further include the shaft close to filter vat one end, shaft through Rose Box and be located at one end in Rose Box
Some blades are equipped with, the other end of shaft is fixed on filter vat, and shaft is coaxially disposed with filter vat；Collecting mechanism includes
It is rotatablely connected with filter vat and receives water ring, ring is collected in the water purification for receiving sewage collecting ring and inner ring that water ring includes outer ring；Sewage collecting
Blow-off pipe is connected with ring, the lower section that ring is collected in water purification is equipped with water purifying tank, and water purifying tank and water purification are equipped with pure water pipe between collecting ring；
The one end of filter vat away from Rose Box is equipped with tabletting, and baffle is equipped with above water purifying tank, and baffle is equipped with what is connected with pure water pipe
Water inlet；Be additionally provided with pressing mechanism on baffle, pressing mechanism includes air storing cavity, piston and block, the top of air storing cavity be equipped with into
Gas port, the bottom of gas storage mouth are equipped with the entrance connected with water purifying tank；Piston is in the "L" shaped being made of montant and transverse slat, transverse slat
It is slidably connected in air storing cavity, spring is equipped between the upper surface of transverse slat and the top of air storing cavity, the top of montant passes through air inlet
Mouth is above air storing cavity；Block is the first magnet being hinged on the inside of air storing cavity, and the lower surface of transverse slat is equipped with the second magnet.
The technique effect of this programme technical characteristic：
Water tank is used to place pending sewage, and suction pump and water inlet pipe are used to sewage importing Rose Box.Rose Box
Interior sewage, by after the contaminant filter of bulky grain, is entered back into filter vat by the filter screen in conduit pipe；And sewage leads to
When crossing water inlet pipe and entering Rose Box, the blade in the installation axle in Rose Box is hit so that blade rotates, and passes through shaft
Filter vat is driven to rotate.
Filter vat, which rotates, can produce centrifugal force, miscellaneous since the quality of the impurity in unit volume is more than the quality of water
Matter can be rotated along the side wall of filter vat, realize the layering of impurity and water.The sewage collecting ring of outer ring is used to that filter vat will to be passed through
The impurity of layering imports, and is discharged by blow-off pipe；The water purification of inner ring collects ring and is used to the water purification after filtering importing water purifying tank
It is interior.
Pressing mechanism is used to add air into water purifying tank, and pressurizes to water purifying tank so that water purification is abundant with air
Contact, so as to fulfill the aeration to water purification.Air is entered in air storing cavity by air inlet, and is rotated by filter vat and driven tabletting
Rotating, tabletting also goes out with montant, presses montant and move down, so as to be moved down with motion plate, extrudes the air in air storing cavity,
So that air enters in water purifying tank, and increase the pressure in water purifying tank, promotion water is fully merged with air.
The technical principle of this programme is：
After sewage intercepting well filter screen filters large granular impurity, by conduit pipe enter filter vat in, and sewage into
There is no blade contact when entering Rose Box so that blade rotates, and drives filter vat to rotate, when filter vat rotates so that sewage
It is subject to centrifugal force, so that impurity is rotated along filter vat side wall；And water purification is rotated in inner ring, and ring is collected by water purification and is led
Enter in water purifying tank, and montant pressed by tabletting, realize air enter water purifying tank in, increase water purifying tank in water purification it is oxygen-containing
Amount, realizes aeration.
What this programme can produce has the technical effect that：
1st, by setting filter vat to rotate so that the larger impurity of unit mass is rotated along filter vat outer wall, realization pair
The separation of impurity and water, can realize the filtering to sewage；
2nd, rotated by filter vat and realize filtering, compared with prior art, impurity will not block sieve, it is not necessary to often more
Sieve is changed, therefore the efficiency of filtering can be improved；
When the 3rd, entering Rose Box by sewage, blade is impacted, band movable vane piece rotates, can be so that blade drives filter vat to turn
It is dynamic, drive filter vat to rotate without the another actuating unit that sets, the structure of equipment can be simplified；
4th, by setting pressing mechanism, and while being rotated with filter vat, coordinates, and air can be filled with into water purifying tank, and to water purification
Pressurize in pond so that air is closed with the aqueous fusion in water purifying tank, realizes the aeration to the water in water purifying tank.
It is the preferred solution based on such scheme below：
Preferred solution one：Based on base case, the filter vat is in cone-shaped, and filter vat is close to one end of Rose Box
Bigger diameter end.Can be so that the impurity filtered out in filter vat, smoothly exports.
Preferred solution two：Based on preferred solution one, four conduit pipes are evenly equipped between the filter vat and Rose Box.Energy
So that sewage quickly enters in filter vat.
Preferred solution three：Based on preferred solution two, four tablettings are evenly equipped with the outer wall of the filter vat.It can realize quick
Press montant so that substantial amounts of air enters in water purifying tank, increases the oxygen content of the water in water purifying tank.
Preferred solution four：Based on preferred solution three, the top of the montant, which is equipped with, presses block.Briquetting can be facilitated to press perpendicular
Bar.
Preferred solution five：Based on preferred solution four, sieve is equipped with the filter vat, and the aperture of sieve is less than filter screen
Aperture.It can be screened to entering sewage in filter vat, the impurity in the water of inner ring is filtered.
