Abstract
A high-speed shallow sand filter relates to a water filtering device, and solves the problem of low back washing efficiency in the conventional sand filter. The shallow sand filter comprises a tank body, a water inlet pipe, a water outlet pipe, a manhole, a PLC control system, an upper water distributor and quartz sand, wherein a plurality of mushroom-shaped differential pressure compensation filtering water distributors are arranged in the tank body; and the calibre of the top of each mushroom-shaped differential pressure compensation filtering water distributor is smaller than that of the tail thereof; and the number of the mushroom-shaped differential pressure compensation filtering water distributors is 30 to 60. Since the unique mushroom-shaped differential pressure compensation filtering water distributors are arranged in the tank body, the balanced water pressure of all parts is ensured in the filtering state, the filtering flow rate is high, the efficiency is high, an internal-loop flow is formed in the back washing state, the back washing efficiency is high, and the sand leaking phenomenon is avoided; the calibre of the top of mushroom-shaped differential pressure compensation filtering water distributor is smaller than that of the tail thereof, so that the pressure at the mushroom head outlets on the water distributors is basically identical, the impurity discharge is facilitated during the back washing process, the back washing period is shortened, and the back washing effect is good.
Description
Technical field
The utility model relates to a kind of water filtering device, is a kind of shallow-layer high rate sand filter specifically.
Background technology
Shallow-layer high rate sand filter system can be applied to various water treatment fields, as give water filtration, cooling circulating water is filtered entirely and other filter, sea water filter, waste water treating and reutilizing etc., is the first-selection that substitutes traditional sand filter, valveless filtering pool.In the sand filter of using at present on market, the filtration state can not guarantee the each several part hydraulic balance, causes the damage of lower water-dispensing device under the backwash state easily, and backwash efficient is low and run sand easily.Filtration flow-rate is low, efficient is not high.Because pressure is unbalanced, impurity is difficult for discharging in the backwash process, and filtrate hardens easily, DeGrain.
Summary of the invention
In order to solve the problem of above-mentioned existence, the shallow-layer high rate sand filter device that the utility model provides that a kind of filtering velocity is higher, filter effect better, filtrate is not easy to harden, backwash efficiency is higher.
The purpose of this utility model is achieved through the following technical solutions: the shallow-layer high rate sand filter, comprise tank body, water inlet pipe, outlet pipe, manhole, PLC control system, upper water distributor, quartz sand, it is characterized in that: be provided with some mushroom pressure difference compensation filter cloth hydrophones in tank body, described mushroom pressure difference compensation filter cloth hydrophone top bore is less than the afterbody bore.
The quantity of described mushroom pressure difference compensation filter cloth hydrophone is 30-60.
The beneficial effects of the utility model: the utility model adopts said structure, in tank body, be provided with several unique mushroom pressure difference compensation filter cloth hydrophones, under the filtration state, can guarantee the each several part hydraulic balance, filtration flow-rate height, efficient height, circulation in the backwash state forms down, backwash efficient is high and do not run sand.Mushroom pressure difference compensation filter cloth hydrophone top bore makes the pressure basically identical of each mushroom head outlet on the water-locator less than the afterbody bore, is beneficial to impurity discharge in the backwash process, shortens the backwash cycle, and backwash is effective.
Description of drawings
Fig. 1 is the general illustration of shallow-layer high rate sand filter.
Fig. 2 is the structural representation of mushroom pressure difference compensation filter cloth hydrophone;
Fig. 3 is a shallow-layer high rate sand filter water-locator internal structure schematic diagram.
The specific embodiment
A kind of shallow-layer high rate sand filter, comprise tank body 1 and PLC control system, tank body 1 is a carbon steel material, internal layer is made by black polyethylene, can resist the pressure of environment, prevent embrittlement and not corroded by chemical substance, be provided with water inlet pipe 2 at tank body 1 top, manhole 4, be provided with outlet pipe 3 in tank body 1 bottom, in tank body 1, be provided with upper water distributor 5 and mushroom pressure difference compensation filter cloth hydrophone 7, quartz sand 6, the quantity of mushroom pressure difference compensation filter cloth hydrophone 7 can be provided with 30-60 as required, and wherein the top bore of each mushroom pressure difference compensation filter cloth hydrophone 7 is less than the afterbody bore, and the operation of whole shallow-layer high rate sand filter is controlled by the PLC control system.
Claims (2)
1. shallow-layer high rate sand filter, comprise tank body, water inlet pipe, outlet pipe, manhole, PLC control system, upper water distributor, quartz sand, it is characterized in that: be provided with some mushroom pressure difference compensation filter cloth hydrophones in tank body, described mushroom pressure difference compensation filter cloth hydrophone top bore is less than the afterbody bore.
2. shallow-layer high rate sand filter according to claim 1 is characterized in that: the quantity of described mushroom pressure difference compensation filter cloth hydrophone is 30-60.
