Abstract
The utility model relates to an adjustable float fiber filtering material density regulating device, which comprises an exhaust port regulating mechanism, a float, a connecting piece, a grid plate and a fiber filtering material, and is characterized in that the lower portion of the float is provided with an opening, the top portion is provided with an exhaust port regulating mechanism, the grid plate is a block, the fiber filtering material is suspended between the block grid plates, and a grid plate arranged on the top portion is fixed on the lower opening of the float. The adjustable float fiber filtering material density regulating device can stably pull up polluted fiber filtering material to achieve positive and negative cleaning, can lead the filtering material to be thoroughly cleaned, stably runs, is not easy to damage components, prolongs filtration cycle, and reduces filtration cost. The adjustable float fiber filtering material density regulating device is widely used in a fiber filtering material density regulating device which uses ring-shaped fiber as the filtering material.
Description
Technical field
The utility model relates to a kind of adjustable type float-type fiber filtering density regulating apparatus.
Background technology
The fibrae circulares that is entwined need be regulated its density as the filter plant filtrate, and fiber filtering density needs to strengthen during filtration, makes it form filter bed and filters; Filtrate needs pull-up to make it be in free relaxed state again when cleaning, and is convenient to utilize purgative gas, water to clean to its suspension of being held back when filtering.
The density regulating apparatus of fiber filtering has stop valve type at present, and its structure is equipped with several non-return valves on the orifice plate that hangs fiber sealing plate being installed on sealing plate; This structure major defect can not realize that forward cleans, and non-return valve is fragile, complex structure cost height, and water distribution is even inadequately during filtration, and because movement velocity is unadjustable, card takes place and bumps phenomenon in bumpy motion under backwash gas, water slug, easy and barrel during cleaning.
The density regulating apparatus of another kind of fiber filtering is that fixing hole is board-like, its structure is fixed for the orifice plate that hangs fiber, there is long nylon rope in every group of fiber filter element upper end system, form filter bed during filtration, top nylon rope is stretching, under the impact of backwash gas, water, fiber filter element stretches during cleaning, and have one deck loose nylon rope above the filter element this moment; This structure major defect also is to realize that forward cleans, and the loose nylon rope of this layer easily twines mutually and influence the filtrate operate as normal in addition.
The density regulating apparatus of above-mentioned two kinds of fiber filterings can only clean in the other direction to filtrate, cleans owing to can not realize forward, and the suspension of filtrate trapped inside not easy cleaning is thorough.
Summary of the invention
The purpose of this utility model is to provide a kind of adjustable type float-type fiber filtering density regulating apparatus.
The adjustable type float-type fiber filtering density regulating apparatus that the utility model proposes, form by exhaust outlet governor motion 1, floating drum 2, connector 3, flase floor 4 and fiber filtering 5, wherein, floating drum 2 lower openings, the top is provided with exhaust outlet governor motion 1, flase floor 4 is 2, is hung with fiber filtering 5 between 2 flase floors 4, and a flase floor 4 that is positioned at the top is fixed in floating drum 2 lower openings places by connector 3.
In the utility model, during use this device is positioned in the filter tank, the size of floating drum, quantity, shape are determined according to the size and the structure in whole filter tank.
In the utility model, it is most important to filtering technique whether the fiber filtering 5 after the filtration obtains thorough cleaning and regeneration, rinse water is only arranged, and backwash can not be with the cleaning of fiber filtering 5 trapped inside suspensions thoroughly from bottom to top, and also will have rinse water just washing from top to bottom could clean filtrate trapped inside suspension thoroughly; The utilization of the utility model device is cleaned the gas of emerging behind the fiber filtering and is made aeration of float, thereby produces buoyancy with flase floor and fiber filtering pull-up, and filtrate is in free relaxed state all the time and can carries out two-way cleaning easily under the position-limit mechanism restriction; Make steadily no card group of flase floor motion by regulating the control steam vent governor motion of installing on floating drum top.
The utility model can be realized the positive and negative two-way cleaning of fiber filtering, makes fiber filtering clean more thoroughly, does not need additionally to increase equipment, no consumable accessory simple in structure, and no jam accident operates steadily.Because the fiber filtering cleaning method is reasonable, can save scavenging period, to save rinse water and clean power, fiber filtering cleans thoroughly can also prolong filter cycle.
This device can be widely used in using the filtrate density regulating apparatus of fibrae circulares as filtrate, and filtrate is thoroughly cleaned, and for the water quality and the water yield that improve water outlet, reducing the filtration cost has significance.
Description of drawings
Fig. 1 is a structural diagrams of the present utility model.
Number in the figure: 1 is the exhaust outlet governor motion, and 2 is floating drum, and 3 is connector, and 4 is flase floor, and 5 is fiber filtering.
The specific embodiment
Further specify the utility model below by embodiment.
Embodiment 1:
As shown in Figure 1, this device is made up of exhaust outlet governor motion 1, floating drum 2, connector 3, flase floor 4 and fiber filtering 5, the floating drum 2 usefulness connectors 3 of lower openings are fixed on the flase floor 4 that is hung with fiber filtering 5, and floating drum 2 tops are equipped with the exhaust outlet governor motion 1 of control steam vent size.Selecting long and wide respectively is 2 meters one in filter tank, and being evenly equipped with on the flase floor 4 of suspension fiber filtering 5 and fixing volume with connector 3 is 90 liters 6 on floating drum, and the exhaust outlet governor motion 1 at each floating drum 2 top all adopts the DN25 valve.
Under fiber filtering 5 gas, water cleaning state, when moving for the first time,, adjust the opening of the exhaust outlet governor motion 1 of each floating drum 2 according to the flase floor 4 upper and lower operation conditions that hang fiber filtering 5, it is operated steadily; Because it is suitable that exhaust outlet governor motion 1 opening of this floating drum is regulated, the buoyancy that floating drum 2 produces is convenient to conveniently it thoroughly be cleaned all the time with fiber filtering 5 pull-ups; Finish when fiber filtering 5 cleans, after purgative gas, water stopped, gas slowly was discharged by exhaust outlet governor motion 1 in the floating drum 2, and under gravity effects such as former impact of water and flase floor 4, fiber filtering 5 density strengthen gradually, form filter bed and filter.
Through trying out, can realize that to the positive and negative two-way cleaning of fiber filtering filtrate cleans comparatively thorough, the device motion is steadily compared with original structure, prolongs 20% filter cycle, and rinse water and cleaning required drive reduce 15%.The water quality and the water yield of water outlet meet standard-required, reach leading domestic level.
