Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
Fig. 1 is the left view of rotary drum Microfilter in the utility model embodiment, and Fig. 2 is the sectional view along A-A line in Fig. 1, and Fig. 3 is the sectional view along E-E line in Fig. 2, and Fig. 5 is the close-up schematic view along B-B line in Fig. 3.Composition graphs 1, Fig. 2, Fig. 3 and Fig. 5 known, the rotary drum Microfilter of the present embodiment comprises: shell 1, lauter tub 4, motor 10, back purge system and control system.
Its housing 1 is the container of water after filtering, and select polygon bucket, wherein bottom transverse cross section is trapezoidal, and easy to clean, without dead angle.
The material of shell 1 can select the material with some strength and corrosion resistance, preferred 316L stainless steel in the present embodiment.
The middle part of the water inlet side of shell 1 is provided with water inlet pipe 2, and the bottom of water outlet side is provided with outlet pipe 11, and in the middle part of water outlet side, side is provided with sewage draining exit 9.
Water inlet side in shell 1 is provided with ring baffle 13, can reduce the impact of water inlet current to filter screen, improves the life-span of filter screen.
Water outlet side in shell 1 is provided with water outlet baffle plate 12, can make to maintain certain water level in shell 1, and provide certain suspending power, the pressure and the lauter tub 4 that alleviate lauter tub 4 pairs of shells 1 rotate required power, therefore reach energy-conservation effect.
It is supreme that motor 10 is fixed on shell, for driver output axle 8, and then drives lauter tub 4 to rotate.The concrete fixed position of motor 10 can set as required, and the top of the water outlet side of the present embodiment housing 1 is fixedly connected with motor 10.
Lauter tub 4 is positioned at shell 1, and the runing rest of lauter tub 4 is fixedly connected with shell 1, wherein--and lauter tub 4 water inlet side is connected with shell 1 by being arranged with two support fast pulleys 3 on top; Lauter tub 4 water outlet side is connected with shell 1 by the output shaft 8 being arranged on centre position.
Lauter tub 4 comprises runing rest and is installed on the detachable filter grid on runing rest.
Described runing rest plays the effect of inner support on the one hand, is connected on the other hand, drives the vibration of filter residue guiding gutter in rotary course with filter residue guiding gutter 6, improves water conservancy diversion effect.The present embodiment runing rest adopts 316L stainless steel, corrosion-resistant.
Filter grid is semicircle, and two grids close up the complete cylinder of formation one.Lauter tub 4 of the present utility model can select the even number filter grid of at least two panels according to actual needs.
In addition filter grid site closure is also provided with waffle slab press box 5, for strengthening the intensity of filter grid.
Filter grid comprise cylinder frame and and adhere to filter screen on skeleton, in the present embodiment, preferably drum shape skeleton is polypropylene, lightweight, and motor 10 drives power demand in its rotary course little on the one hand, consumes energy low; Be easy to the suspension band of the tax category to depart from the water surface on the other hand in rotary course, realize good separating effect.
Filter screen adopts terylene material, and be not easy fold, intensity is high, and the life-span is long, and not easily piles up suspension.
The composition that inventor have selected a kind of binding agent comprises SBS resin, rosin and solvent naphtha, and bond effect is best, and water resistance is excellent, can reach required technological parameter.Filter screen is adhered on skeleton by above-mentioned binding agent.
In addition, filter grid single grid area is larger, and filter effect is better, but it is poorer to bear hydraulic pressure ability, therefore needs to consider according to actual needs, selects suitable single grid area.The present embodiment is preferred, and filter grid is square, and the length of side is 2-2.5cm.Because lauter tub is cylindrical shape, skeleton also can be bent into circle, and therefore for ensureing bonding effect and resistance to pressure, the thickness that skeleton is stained with filter screen side is greater than opposite side, and in the present embodiment, the side thickness that skeleton and filter screen bond is 2.5mm, and opposite side thickness is 2mm.
Be provided with filter residue guiding gutter 6 in lauter tub 4, be rinsed for water conservancy diversion the filter residue that system rinses, the filter residue that water conservancy diversion goes out finally flows out from sewage draining exit 9.Filter residue guiding gutter 6 bottom is provided with fagging 7, for fixed support filter residue guiding gutter 6.
Control system comprises the level sensor be arranged in lauter tub 4 and the control device assembly be arranged at outside shell 1.Wherein control device assembly can arrange two kinds of patterns, and one is manual mode, and namely artificial judgment controls the rotation of lauter tub 4 and the unlatching of backwashing system; Another kind is automatic mode, according to the signal feedback of level sensor, automatically controls the rotation of lauter tub 4 and the open and close of backwashing system.
In addition, off delay device is provided with in control device assembly, rotate when control system controls lauter tub 4, after opening backwashing system, after the effect rotated due to backwash and lauter tub 4 makes strainer filtering smooth and easy, water level decreasing in lauter tub 4, after level sensor designated water level lower limit, control signal disconnects, but be provided with off delay device, lauter tub 4 and back purge system time delay running, one can avoid the actual filter screen used always with a part by arranging, and filter screen can rinse more thorough by the two.
Backwashing system comprises ejection-type water pump and cleaning hose 14.
Preferably, in the present invention, wash water selects the water after filtration, flows to the water in shell 1, recycle after namely being filtered by lauter tub 4, cost-saving.
Fig. 4 be in Fig. 3 backwashing system F to schematic diagram.As can be seen from Figure 4, cleaning hose 14 is provided with multiple washable flooding nozzle 15.
Removable nozzle 15, according to filtration water source situation, rationally arranges nozzle number and spacing, Reasonable adjustment backwash ability.Each washable flooding nozzle 15 front end is all provided with spherical adjustable device, and the spherical adjustable device of back flushing nozzle makes each recoil nozzle all in fan douche, and can adjust flushing direction and angle at any time, makes flushing filtering net without dead angle.
When rotary drum Microfilter in the present embodiment works, lauter tub 4 and backwashing system all remain static.The water of cultivating system enters lauter tub 4 from water inlet pipe 2, and after filtering, enter in shell 1, solid suspension is trapped within screen pack, and the water after filtration flows out eventually through outlet pipe 14, reenters in cultivating system and recycles.
When the blocking of lauter tub 4 Inner filter net, when causing water level in lauter tub 4 to rise to level sensor capping height, utilize the electric conductivity (light current) of water body, control signal is connected and returns to control system assembly, at once start jet pump and 10 motors simultaneously, drive lauter tub 4 to rotate, backwash is carried out to lauter tub 4 simultaneously; When rotating due to lauter tub 4, after making filter screen unobstructed with the effect of recoil, strainer filtering area increases, water level decreasing in lauter tub 4, lower in limited time lower than level sensor setting, control signal disconnects, and owing to arranging off delay function (this delay time can regulate arbitrarily according between actual requirement 1S ~ 60S) in control system assembly, time delay operates.After time delay running terminates, equipment gets back to again normally static duty.So go round and begin again operation.
Although the utility model discloses as above with preferred embodiment, the utility model is not defined in this.Any those skilled in the art, not departing from spirit and scope of the present utility model, all can make various changes or modifications, and therefore protection domain of the present utility model should be as the criterion with claim limited range.
