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, curved surface fine fack generally commonly used separates with sewage for grid slag in the sewage; Because of this equipment has small investment, characteristics such as non-power consumption, but sewage complicated component, surface tension of liquid cause the curved surface fine fack to be prone to stop up more greatly; Need to be equipped with rinse-system, involve great expense complex operation; And grid slag moisture content is high, has caused difficulty to subsequent treatment.
Summary of the invention
Problem to existing in the prior art the objective of the invention is to: in order to overcome the weak point of above-mentioned curved surface fine fack, a kind of fixed vibration curved surface fine fack is provided, it has, and the pulp water separative efficiency is high, advantage such as 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 are provided with ring flange respectively, and being spirally connected of ring flange is to seal through 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, practices thrift 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 high more, and surface tension of liquid is big more, and liquid is slow more through the speed that grid gap and solids leave;
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 the influence of above-mentioned three factors to 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 receives the frequent effect of gravity and centrifugal force, impulsive force, frictional force and inertia force; Can reduce surface tension of liquid effectively, improve the flow velocity of liquid through the grid seam; Vibration makes that solia particle is difficult for improving the self-cleaning ability of curved surface grid attached to the grizzly bar surface; Foreign material after the also feasible separation of vibration and the frictional force between the curved surface grizzly bar diminish, thereby reduce foreign material in the time of staying of curved surface grid, improve 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 improved the speed of liquid through the 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 an 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 convenience for washing;
Four, the complete machine material adopts the stainless steel manufacturing, and mechanical strength is high, indeformable, the life-span is long.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further to set forth in detail.
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 curved grid face 4 and the curved grid face that special stainless steel wedge shape rod iron forms through Precision Machining is 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 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 a stainless steel 304, is welded; Said water inlet 1, drain 7 and delivery port 8 all are furnished with flange, connect with sealing gasket and bolt; Said 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; Said 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 on platform, to do draining, and necessary catch pit is set.
Workflow:
Pending solidliquid mixture gets into material-storing box from water inlet pipe, is evenly distributed on the curved grid face along grid face width degree through downflow weir.Grid face down mobile mixed liquor in self gravitation effect lower edge; Because the grid face is curved structure, mixed liquor produces centrifugal force downward the work in the even acceleration flow process, and 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 along the grid face under the effect of thrust that self gravitation, liquid flow produce and vibration force fast, 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 commercial 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.
