Disclosure of Invention
Technical problem to be solved
The invention provides a sewage treatment multistage filtration sedimentation tank, and aims to solve the following problems in a sedimentation tank in the prior art: (1) the sedimentation tank is used for a period of time, and then the garbage on the filter screen needs to be collected and transferred, and because the area of the sedimentation tank is large, a large amount of manpower is needed to be consumed when the garbage is collected and transferred, and the efficiency is low; (2) after the sedimentation tank is used for a period of time, the sludge at the bottom of the tank needs to be scraped by emptying the tank water, and the dredging cost is higher and the efficiency is lower when manual work or a dredging robot is adopted for processing.
(II) technical scheme
In order to solve the technical problems, the invention adopts the following technical scheme:
The utility model provides a sewage treatment multistage filtration sedimentation tank, includes that top-down sets up one-level filtering mechanism and second grade filtering mechanism on first inside wall to and the desilting mechanism of setting on the adjacent second inside wall of first inside wall. A water inlet and a water outlet are formed in the first inner side wall. First-order filtering mechanism includes the first spacing of horizontal fixed mounting on first inside wall, and first spacing is located the top of water inlet, and horizontal sliding fit has the first slide bar that is on a parallel with first inside wall in the first spacing. Vertical fixed mounting has the spacing frame of second on the first inside wall, and the spacing below that is located the water inlet of second, and vertical sliding fit has the second slide bar that is on a parallel with first inside wall in the spacing frame of second. One side of the first filter screen is arranged on the first sliding rod, and the other side of the first filter screen is arranged on the second sliding rod. The first filter screen is of a flexible and deformable structure. The second grade filtering mechanism includes the second filter screen of horizontal installation on first inside wall, and the second filter screen is located the below of spacing frame of second, and the single mesh area of second filter screen is less than the single mesh area of first filter screen. The first sliding rod is positioned at one end, far away from the first inner side wall, of the first limiting frame, and when the second sliding rod is positioned at the bottom end of the second limiting frame, the first filter screen is in a maximum opening state. When sewage passes through the first filter screen, the first filter screen filters waste such as scraps of paper and plastic bags in the sewage. After the sedimentation tank uses a period, when needing to clear up rubbish on the first filter screen, with the one end that is close to first inside wall in first slide bar pulling to first spacing, promote the second slide bar to the top in the spacing of second, first filter screen is in the rolling state, has realized the automatic collection to rubbish, then take off first filter screen from first slide bar and second slide bar, clear up rubbish can.
The desilting mechanism comprises a step fixedly arranged at the bottom of the second inner side wall, the step is positioned below the water outlet, and the top surface of the step is in an arc shape with the middle part sunken downwards. The top surface of step is seted up the bar recess along its length direction, and bar recess bottom intercommunication seal groove. The surface laminating of recess has plastic film, and the briquetting runs through plastic film and vertical sliding fit in the seal groove, and the vertical lift bar of top fixedly connected with of briquetting, the bottom of briquetting have the separation blade that two symmetries set up through torsion spring is articulated, and the initial condition of separation blade is the horizontality. Because the top surface of the step is in the shape of an arc with the middle part sunken downwards, the plastic film is in the shape of the middle part sunken downwards, and sludge can be accumulated in the middle part of the upper surface of the plastic film. The briquetting contradicts plastic film's edge on the groove face of bar recess, plays sealed effect to sewage, prevents that sewage from getting into the plastic film lower surface. When the silt to the plastic film upper surface is cleared up, the pond normal water is emptied earlier, then drives the briquetting upward movement through the lifter bar, and briquetting upward movement breaks away from the seal groove after, and the separation blade resumes the horizontally initial condition under torsion spring's effect, and the separation blade plays the effect of bearing to plastic film's edge, promotes plastic film to the top of sedimentation tank. And finally, rotating the blocking piece to ensure that the blocking piece does not bear the plastic film any more, and taking down the plastic film.
As a preferable technical solution of the present invention, a horizontal mounting groove is formed on the first inner side wall, a first sleeve with an upward opening is fixedly mounted on a groove bottom surface of the mounting groove, and a second sleeve with a downward opening is fixedly mounted at a position of a groove top surface of the mounting groove corresponding to the first sleeve. The bottom of the first spring is fixedly arranged in the first sleeve, and the top of the first spring is fixedly arranged in the second sleeve. The second sleeve is fixedly connected with the second filter screen. The long-time accumulation of dirt particles in the sewage on the second filter screen can block the filter holes of the second filter screen. The sewage that comes out from the water inlet strikes the second filter screen, and the second filter screen transmits the impact force of sewage for the second sleeve, and the second sleeve drives the second filter screen reciprocating vibration from top to bottom under the effect of first spring, piles up the filth granule on the second filter screen and breaks away from the second filter screen under the vibration effect, has avoided the filtration pore of second filter screen to block up.
As a preferred technical scheme of the invention, the dredging mechanism further comprises a sealing mechanism, the sealing mechanism comprises an installation plate fixedly arranged on the lifting rod, a first threaded hole in the vertical direction is formed in the installation plate, a second threaded hole corresponding to the first threaded hole vertically penetrates through the pressing block, a bolt is matched in the first threaded hole and the second threaded hole, and a rubber head is fixedly arranged at the bottom of the bolt.
