The utility model adopts filter aid automatic feeding tank to add diatomite, can reduce the issuable error of artificial participation so that add intelligent automaticization of process, improves the diatomite utilization ratio, has also promoted filtration vessel levels.Wherein, the startup that adds of filter aid automatic feeding tank is started according to hydraulic pressure pressure reduction by switch board, stops by time control, and diatomaceous automatic switching laying mechanism can adopt various mechanism, and now existing commercially available, and no longer expansion is described herein.
Wherein, described water pump 3 and its drive motors are fixedly installed on the base, and its water inlet is connected to the delivery port of hair catcher through advancing the first water inlet pipe 12, and the delivery port of described water pump is connected to the water main inlet port of cross valve 4 through the second water inlet pipe 13.
The valve body of described cross valve is one and has the radially housing of valve opening four different azimuth, be lined with liner in the valve opening, be connected with four pipelines simultaneously by flange valve gap or valve seat at each valve opening place, wherein, water main inlet port is communicated with pump outlet, main delivery port is communicated with triple valve, and two other valve opening is connected to respectively diatomite sheet frame reversible filter two ends.The revolving body spool that can freely rotate around self axis is housed in the described valve body, spool gyroaxis one end has the spindle nose of rotation to join with turning handle, certainly for improving the intelligent of control, described rotation spindle nose also can be by motor-driven, when control during valve core rotation, it is constant that it guarantees that water main inlet port and main delivery port flow to, and the flow direction of switching two other outlet is to realize positive and negative filtration, described cross valve can adopt the commercially available prod, does not repeat them here.
The bottom of the left and right sides of described diatomite sheet frame reversible filter 5 is connected to respectively the valve opening of cross valve by the road with pipeline, a plurality of filter frames in two end sockets form by a pair of end socket that is arranged on two ends and clamping position for it, whole filter is fixedly connected with the end socket at two ends with fishbolt that will to be arranged in simultaneously inboard filter frame fastening and make its sealing, in filter frame, be fixedly installed filter cloth, described filter cloth has certain intensity, films thereon in order to hold diatomite.Diatomite be by time immemorial unicellular alga aquatic organism remains deposit form through retrofit, its light specific gravity, adsorptivity are strong, rational size distribution, specific area is large, voidage is high, flow is large, clarity is good, content of beary metal is low, stable chemical performance, strong adaptability, can be used as reliably the fine filtering medium.
Described diatomite and dirt recover 6 comprise support and by the collecting tank of stent support, be provided with filter mechanism in the described collecting tank, as filter pocket etc., the water inlet of water from its top that is mingled with impurity enters after filtering and again enters raw water tubes from the delivery port discharge of bottom and through circulation line, and the closed type that circulated is filmed.
Further, intelligent for improving product control, described triple valve is electric T-shaped valve, utilizes switch board can control it and switches stream, whole equipment all can move automatically, need not manual intervention, greatly liberates the labour, can carry out unattended.
When concrete the use, at first control described cross valve and just filtering station, triple valve is at the backwash station, be that triple valve is with diatomite and dirt recover and cross valve conducting, this moment, the drainage control valve was closed and circulation control valve is opened, the driven by motor pump working, swimming-pool water is through entering the hair catcher, enter in the water pump and along the second water inlet pipe through the first water inlet pipe through the water after the coarse filtration and to enter cross valve, filter aid automatic feeding tank injects the diatomite mixed liquor in the first water inlet pipe simultaneously, current enter cross valve from pipeline and enter diatomite sheet frame reversible filter by the pipeline outflow, diatomite can the rapid side that meets water at filter cloth form filter membrane, whole be coated with that membrane process adopts former water and the water of discharging from diatomite sheet frame reversible filter through cross valve, enter diatomite and dirt recover behind the triple valve and then enter raw water tubes, the whole membrane process that is coated with emits no waste water.After the scheduled time, such as 3min, to film complete, the control triple valve switches to the filtration station, is about to cross valve master discharge outlet and is communicated to the drainage pipeline, and the drainage after the diatomite sheet frame reversible filter through filming complete filters can be exported through the drainage pipeline.Close at last circulation control valve.
After using a period of time, diatomite sheet frame reversible filter pressure at two ends reaches threshold value, such as 0.08Mpa, the control cross valve is to the anti-station that filters, triple valve is to sending out the flushing station, open circulation control valve, start simultaneously filter aid automatic feeding tank and in the first water inlet pipe, inject the diatomite mixed liquor, current enter cross valve from the second water inlet pipe and oppositely enter diatomite sheet frame reversible filter by the pipeline outflow, reverse flow washes away the simultaneously rapid side formation filter membrane that meets water at filter cloth through the current of filter cloth with filter membrane and the impurity that the filter cloth land side has existed, and the current that pass filter cloth are mingled with the impurity that is attached on the filter membrane and flow out by the road diatomaceous earth filter and again return cross valve, enter by the road diatomite and dirt recover by main delivery port at last, diatomite and dirt recover are to being mixed in the impurity absorption in the water and discharging clean water, clean water can enter circulation through circulation line again, whole cyclic process emits no waste water, reach the scheduled time, behind 3mi n, oppositely film complete, the control triple valve enters the normal anti-station that filters to filtering station and closing circulation control valve.When backwash, when filter cloth is filmed again, stop outside draining and utilize diatomite and the dirt recover reclaims dirt, avoid being coated with and produce sewage in the membrane process and discharge, and in being coated with membrane process, adopt recirculated water to film, zero-emission improves Environmental Protection Level.
After using a period of time, because continuing to increase, the impurity on the diatomite filtration film again cause both sides pressure reduction to raise, in the time of need to instead filtering, only need above-mentioned step is repeated to implement to get final product, whole backwash process can not produce waste water equally, has saved water resource, controls simple cost low.
The above only is preferred embodiment of the present utility model; should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
