Description
Technical field
The present invention relates to the curved surface fine fack in a kind of sewage disposal device, be specially a kind of fixed vibration curved surface fine fack.
Background technology
At present, in the sewage preprocessing process of industrial wastewater and micropolis sewage treatment plant, general curved surface fine fack commonly used separates with sewage for grid slag in the sewage, because this equipment has small investment, and characteristics such as non-power consumption, but sewage complicated component, surface tension of liquid cause the curved surface fine fack easily to stop up more greatly, need to be equipped with rinse-system, involve great expense complex operation, and grid slag moisture content height has caused difficulty to subsequent treatment.
Summary of the invention
At problems of the prior art, the objective of the invention is to: in order to overcome the weak point of above-mentioned curved surface fine fack, provide a kind of fixed vibration curved surface fine fack, advantage such as it has pulp water separative efficiency height, be difficult for stopping up, reducing investment outlay.
Technical scheme of the present invention is achieved in that a kind of fixed vibration curved surface fine fack, comprising: the curved grid face that special stainless steel wedge shape rod iron forms through Precision Machining; Short arc, high-frequency electromagnetic oscillation device; The top is provided with the cloth tank; Curved grid face is provided with flexible pressing plate; The cloth tank is provided with water inlet and drain; Curved grid face bottom is provided with water leg and delivery port.
Described import and export and drain arrange ring flange respectively, and being spirally connected of ring flange is to seal by seal washer.
Fixed vibration curved surface fine fack has increased short arc, high-frequency electromagnetic oscillation device, makes that grid face tilt degree can be littler than common curved surface grid, and it is nearly 50% that same discharge area can be raised the efficiency, and increases disposal ability, saves operating cost.
The factor that influences curved surface grid treatment effeciency mainly contains following several aspect:
1, the viscosity of pan feeding solidliquid mixture, viscosity is more high, and surface tension of liquid is more big, and the speed that liquid separates with solid by the grid gap is more slow;
2, solia particle adheres to grizzly bar, causes the grid area to diminish along with the increase in processing time;
3, rest on the whether landing fast of grid slag of grid face, the discharge area of remaining valid.
In order to reduce above-mentioned three factors to the influence of solid-liquid separation efficiency, utilizing vibration principle is one of more effective settling mode.Because vibration can make solid-liquid mixture be distributed on the working face quickly and evenly, while material on vibration plane is subjected to the frequent effect of gravity and centrifugal force, impulsive force, frictional force and inertia force, can reduce surface tension of liquid effectively, improve liquid by the flow velocity of grid seam; Vibration makes solia particle be difficult for being attached to the grizzly bar surface, improves the self-cleaning ability of curved surface grid; Foreign material after vibration also make to separate diminish with the frictional force between the curved surface grizzly bar, thereby reduce foreign material in the time of staying of curved surface grid, the raising separative efficiency.
Vibration curved surface grid adopts stainless steel strip to stitch curved grid face, and grizzly bar is for trapezoidal, and grid face upper surface gap is little, level and smooth like this, and back gap is big, and the draining of grid face is smooth and easy, is difficult for blocking.
In order further to improve separative efficiency, vibration curved surface grid is provided with flexible pressing plate especially on the grid face, and when mixed liquor passed through the grid face, under the effect of flexible pressing plate, the interior pressure of mixed liquor increased, thereby improves liquid by the speed of curved surface grid.
The present invention is directed to the characteristics of curved surface grid, its structure is carried out scientific and reasonable improvement, it has following advantage with present comparing:
One, low energy consumption: the vibration curved surface grid with 800 * 1600 grid faces is example, and only 60 watts of the power of its vibrating device are equivalent to the power consumption of a bulb;
Two, the unit treating capacity is big: under equal contrast condition, its separative efficiency can improve more than 50%;
Three, have the self-cleaning ability, the grid seam is difficult for blocking, and cleans conveniently;
Four, the complete machine material adopts the stainless steel manufacturing, the mechanical strength height, indeformable, the life-span is long.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is further elaborated.
Shown in Fig. 1-4, the fixed of present embodiment vibration curved surface fine fack, it comprises the overflow water distribution system that water inlet 1, cloth tank 2 and drain 7 are formed; The screening system that the flexible pressing plate 11 that the curved grid face 4 that special stainless steel wedge shape rod iron forms through Precision Machining and curved grid face are provided with constitutes; Short arc, high-frequency electromagnetic oscillation device 5, vibrating sensing rod 9 and resonance rod 3,6 constitute vibrational system; The collection outlet system that the water leg 10 that curved grid face bottom is provided with and delivery port 8 are formed; General frame support system 12.
Described cloth tank 2 inside are provided with downflow weir, and material is stainless steel 304, is welded; Described water inlet 1, drain 7 and delivery port 8 all are furnished with flange, connect with sealing gasket and bolt; Described curved grid face 4 is formed through Precision Machining by special stainless steel wedge shape rod iron, and the grid spacing is 2mm, and cambered surface radius is 2.5m; Described vibrating sensing rod is that the rod iron of 90mm is made by diameter, and resonance rod diameter is 60mm, and sensing rod, resonance rod add strong weld with grid face baffle plate and fix.
Fixed vibration curved surface fine fack is installed very convenient, generally is positioned on the concrete platform, and it is domatic to need to consider to do draining at platform, and necessary catch pit is set.
Workflow:
Pending solidliquid mixture enters material-storing box from water inlet pipe, is evenly distributed on the curved grid face along grid face width degree by downflow weir.Mixed liquor faces down mobile at self gravitation effect lower edge grid, because the grid face is curved structure, mixed liquor produces centrifugal force in making even acceleration flow process downwards, liquid passes through the grid face fast under action of centrifugal force, and lumpiness greater than the solid sundries of grid seams size since the obstruct of grizzly bar be trapped within on the grid face, it is fallen in the collecting pit to lower slider fast along the grid face under the effect of thrust that self gravitation, liquid flow produce and vibration force, realizes the Separation of Solid and Liquid process.
Fixed vibration curved surface fine fack can reduce concentration of suspension in the water effectively, alleviates the processing load of subsequent handling.Also being used for simultaneously industrial production and carrying out Separation of Solid and Liquid and reclaim utility, is a kind of good filtration or the highly-efficient equipment that reclaims solid-state or colloidal substance such as suspension, floating thing, sediment.
Though the present invention with preferred embodiment openly as above; but embodiment and accompanying drawing are not to limit the present invention, anyly are familiar with this skill person, without departing from the spirit and scope of the invention; from when doing various variations or retouching, belong to the present invention's protection domain equally.Therefore protection scope of the present invention should with the application claim was defined is as the criterion.
