Abstract

A kind of vertical sedimentation basin the utility model discloses perforation water distribution and with mud-scraping apparatus, including pond body, settling zone, sludge bucket, water inlet pipe, central tube, horn mouth, perforation cloth water ring, conical baffled, suspension rod, braiding channel, effluent weir, scum board, mud scraper, outlet pipe and return duct etc..The utility model perforation water distribution and the vertical sedimentation basin with mud-scraping apparatus can solve the problems, such as that conventional vertical sedimentation basin easily produces Mud up-floating.

Description

A kind of perforation water distribution and the vertical sedimentation basin with mud-scraping apparatus
Technical field
This practical patent is related to a kind of equipment for separating liquid from solid, and in particular to a kind of perforate water distribution and erecting with mud-scraping apparatus Flow settling pond, belong to technical field of waste water processing.
Background technology
Vertical sedimentation basin is the sedimentation basin that waste water vertically flows in pond.Conventional vertical sedimentation tank pond body planar graph is circle Shape is square, and water is entered in pond from top to bottom by the water inlet pipe for being located at pond center, and pipe, which divides into umbrella-shaped baffle, makes waste water in Chi Zhongjun Slowly rise along the whole cross-section of river after even distribution, suspended substance sedimentation enters in bottom of pond taper sludge bucket, and primary water is from pond surrounding Peripherally downflow weir flows out.Baffled or scum trough ensures effluent quality to retain scum silica frost before weir.The one side in pond sets row by pool wall Mud pipe periodically discharges mud by hydrostatic pressing.The advantages of vertical sedimentation basin is that floor space is small, is usually used in processing water and is less than 20000m3/d sewage treatment plant.
At present, in small sewage treatment plant, vertical sedimentation basin be widely adopted as biochemical treatment after second pond, But the shortcomings that one very big in the process of running, be present is exactly that spoil disposal is not thorough, it is high easily to produce Mud up-floating, particularly summer Warm weather, this phenomenon is particularly evident, stronger mainly due to the general viscosity of biochemical sludge, and clarifier sludge headwall typically will not It is especially smooth, so easily bonding is attached on sludge headwall sludge, it will not slip into sludge bucket and discharge automatically, make in the course of time Cause second pond Mud up-floating into anaerobic digestion or denitrification, influence treatment effect.
Therefore, in order to solve the above technical problems, it is necessory to be improved to conventional vertical sedimentation basin.
The content of the invention
In order to solve the above technical problems, the purpose of this utility model is that solving conventional vertical sedimentation basin easily produces dirt The problem of mud floats, it is directed to sludge in conventional vertical sedimentation basin, and easily bonding is attached on sludge headwall, and mud dress is scraped in increase Put, and improve water-distributing device and central tube, thoroughly solve the halfway problem of spoil disposal.
To achieve the above object, the technical scheme that the utility model is taken is:A kind of perforation water distribution and with mud-scraping apparatus Vertical sedimentation basin, including pond body, settling zone, sludge bucket, water inlet pipe, central tube, horn mouth, perforation cloth water ring, it is conical baffled, Suspension rod, braiding channel, effluent weir, scum board, mud scraper, outlet pipe and return duct etc..
A kind of perforation water distribution and vertical sedimentation basin with mud-scraping apparatus, the mud-scraping apparatus by driving decelerating electric machine, in Mandrel and cleaning shoe form, centered on driven type, central shaft is located at pool center, and top is connected with driving motor, driving motor It is fixed on walkway board, bottom is fixed on sludge bucket bottom, and cleaning shoe is fixed on center shaft, and is covered according to the shape of sludge bucket Cover whole sludge bucket pool wall.
Further, in addition to perforation cloth water ring, perforation cloth water ring connect water inlet pipe in central tube, are then wrapped around scraping mud dress Central shaft is put, forms an annular, cloth water ring upper end perforate of perforating, water overflows from upper end, flowed downward in central tube, then enter Enter settling zone.
Further, it is in addition to conical baffled, it is conical baffled to be separated with central tube, it is fixed on the central shaft of mud-scraping apparatus On, rotated with central shaft.
Further, the sludge bucket bottom is provided with mud return line, and mud return line can be with external reflux pump or sludge Well is joined directly together.
Compared with prior art, the utility model has the advantages that:
1. perforation water distribution of the present utility model and the vertical sedimentation basin with mud-scraping apparatus are provided with a set of mud-scraping apparatus, Can effectively solve the problems, such as that sludge is attached to pool wall and produces Mud up-floating.
Water distribution and the vertical sedimentation basin with mud-scraping apparatus 2. the utility model is perforated, its water distribution use perforation cloth water ring, Enclosed around mud scraper central shaft one, both optimized water distribution effect, there is the operation without prejudice to mud scraper.
Water distribution and the vertical sedimentation basin with mud-scraping apparatus 3. the utility model is perforated, its it is conical baffled no longer with center Cylinder is connected, and is integrally fixed on central shaft together with axle and rotates, and has both played guide functions, and without prejudice to the operation of mud scraper.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model perforation water distribution and the vertical sedimentation basin with mud-scraping apparatus.
Shown in figure:1st, water inlet pipe 2, central tube 3, horn mouth 4, perforation cloth water ring 5, conical baffled 6, fixed derrick 7th, water leg 8, effluent weir 9, scum board 10, driving decelerating electric machine 11, central shaft 12, cleaning shoe 13, outlet pipe 14th, mud return line.
Embodiment
The utility model is further elaborated below by drawings and examples.
As shown in figure 1, the utility model is a kind of perforation water distribution and vertical sedimentation basin with mud-scraping apparatus, it include into Water pipe 1, central tube 2, horn mouth 3, perforation cloth water ring 4, conical baffled 5, fixed derrick 6, water leg 7, effluent weir 8, scum silica frost gear Plate 9, driving decelerating electric machine 10, central shaft 11, cleaning shoe 12, outlet pipe 13 and mud return line 14.
Operation method using a kind of perforation water distribution of the present utility model and the vertical sedimentation basin with mud-scraping apparatus is as follows:
1), when bringing into operation, by entering central tube 2 after the water distribution uniformity of 1 perforated cloth water ring of water inlet pipe 4, sewage exists sewage Central tube 2 down flows through horn mouth 3 and enters settling zone under conical baffled 5 guide functions, and muddy water is initially separated, and clear water is past It is upper that water leg 7 is entered by effluent weir 8, then next processing unit is entered by outlet pipe 13, sludge sinks, into sludge Bucket, is deposited on sludge headwall, and now driving decelerating electric machine 10 drives central shaft 11 and cleaning shoe 12 to rotate together, will be attached to Sludge scraping on sludge headwall enters sludge bucket bottom, then is discharged or flowed back by mud return line 14.
In order to verify validity of the present utility model, the applicant has carried out the running experiment of one month.By testing Go out to draw a conclusion:During operation of the present utility model, mud-water separation excellent, Mud up-floating phenomenon never occurs.
Foundation embodiment described above is enlightenment, and by above-mentioned description, relevant staff completely can be not In the range of deviateing this invention thought, various changes and amendments are carried out.The technical scope of this item utility model is not The content being confined on specification, it is necessary to which its scope protected is determined according to right.
