Abstract
The utility model discloses the board-like screen device of a kind of punching in field of sewage treatment equipment, comprise cylindric support frame, the periphery of described support frame is coated with punched-plate, and the utility model is arranged on rotary drum filter, compared with existing wedge shape structure of grid, its structure is more simple, and reduce difficulty of processing, discharge area is large, improve sewage treating efficiency, bulk strength is higher, long service life, can be used for rotary drum filter.
Description
Technical field
The utility model relates to a kind of sewage disposal device, particularly a kind of solid-liquid separating equipment.
Background technology
Rotary drum filter is a kind of pretreatment solid-liquid separating equipment for middle or small sewage treatment.Net cylinder rotates under transmission device drives, sewage enters cloth tank from water inlet pipe, evenly overflow from outlet again, the solid matter dropped in the sewage on the net drum outer wall of rotation is retained by screen cloth, water then flows out and enters in collecting-tank from screen cloth gap, and automatically got rid of by scrapper conveyor on screen cloth outer wall by the solid matter that net cylinder retains, net cylinder constantly rotates, the solids be attached on screen cloth outer wall is separated with net cylinder rapidly, thus improves production efficiency.Backwashing system is made up of flushing line and nozzle, water under high pressure is fan-shaped to the ejection at a high speed of net cylinder through nozzle, the solid objects be attached on net cylinder rinsed out rapidly, to form continuous print, without the filtration zone blocked, this filter plant has the features such as efficiency is high, treating capacity is large.Its weak point is, wedge shape structure of grid selected by existing screen cloth, its structural load, and cost is higher, and production efficiency is low.
Utility model content
The purpose of this utility model is to provide the board-like screen device of a kind of punching, simplifies the structure of screen cloth, reduces manufacturing cost.
The purpose of this utility model is achieved in that the board-like screen device of a kind of punching, comprises cylindric support frame, and the periphery of described support frame is coated with punched-plate.
Compared with prior art, the beneficial effects of the utility model are, the utility model is arranged on rotary drum filter, compared with existing wedge shape structure of grid, its structure is more simple, and reduce difficulty of processing, discharge area is large, improve sewage treating efficiency, bulk strength is higher, long service life.The utility model can be used for rotary drum filter.
In order to improve this device functional reliability, strengthen structural strength, described support frame comprises Circular Plate, bearing rib and steel column, described Circular Plate is provided with two pieces, and be distributed in head and the tail two ends, described bearing rib is arranged between two Circular Plate, and Circular Plate and bearing rib circumferentially correspondence offer some circular holes, Circular Plate, bearing rib are fixed together through circular hole by described steel column.
In order to strengthen structural strength further, described steel column and Circular Plate, bearing rib weld together, and described circular hole is evenly distributed on Circular Plate and bearing rib periphery, and tangent with the cylindrical of Circular Plate, bearing rib.The tangent structure in periphery ensure that punched-plate keeps smooth surface indeformable in operation process, and result of use is better.
In order to make this device easier for installation, described two Circular Plate circumferences also evenly offer how dry installing hole, and described installing hole is opened in inside circular hole.
In order to improve the reliability of this device, junction, described punched-plate two ends welds together.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is Circular Plate structural representation in the utility model.
Fig. 3 is bearing rib structural representation in the utility model.
Wherein, 1 Circular Plate, 1a circular hole, 1b installing hole, 2 steel columns, 3 bearing ribs, 3a circular hole, 4 punched-plates.
Detailed description of the invention
The board-like screen device of a kind of punching as Figure 1-3, comprise cylindric support frame, the periphery of support frame is coated with punched-plate 4, support frame comprises Circular Plate 1, bearing rib 3 and steel column 2, Circular Plate 1 is provided with two pieces, and be distributed in head and the tail two ends, bearing rib 3 is arranged between two Circular Plate 1, and Circular Plate 1 and bearing rib 3 circumferentially correspondence offer some circular hole 1a, 3a, steel column 2 is through circular hole 1a, 3a is by Circular Plate 1, bearing rib 3 welds together, circular hole 1a, 3a is evenly distributed on Circular Plate 1 and bearing rib 3 periphery, and with Circular Plate 1, the cylindrical of bearing rib 3 is tangent, two Circular Plate 1 circumferences also evenly offer how dry installing hole 1b, installing hole 1b is opened in circular hole 1a, inside 3a, junction, punched-plate 4 two ends welds together.
With existing wedge shape structure of grid, this apparatus structure is more simple, thus reduces difficulty of processing, and discharge area is large, improves sewage treating efficiency.
The utility model is not limited to above-described embodiment; on the basis of technical scheme disclosed in the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some to some technical characteristics wherein to replace and distortion, these are replaced and are out of shape all in protection domain of the present utility model.
