Abstract
The utility model discloses a filter, comprising a filter main body. The inner part of the filter is provided with a filter plate; a filter hole of the filter plate is provided with a nylon filter cap; the right end of the filter main body is provided with a filling hole. The upper part and the lower part of the left end of the filter are respectively provided with a filter water inlet and a filter water outlet; the filter water inlet is connected with a low-drag water distributing pipe with the equal drag gap; the lower part of the filter is provided with a saddle seat and a vent. Three layers of quartz sand filtering layers are arranged on the filter plate. The utility model has the advantages of strong processing capacity for low turbid raw water, quantity for washing sewage saving, and few power consumption.
Description
The utility model relates to a kind of filter.
Directly filtering technique as far back as nineteen thirty-five China application records is just arranged, once carry out overtesting research the fifties, the later stage seventies begins to carry out the further investigation of system, and successively in Fushun, uses in the extensive water supply project on ground such as Shenzhen.Facts have proved that it is successful that direct filtering technique is used to purify the low former water of turbidity, it is simple that it has technological process, can save precipitation ground, and cost is low, saves advantages such as medicament expense, has now become China and has purified one of technology of the low former water of turbidity.Along with low growth in the living standard, the development of sports.Swimming pool is played the pond constantly to be increased, and resolving the low former water reuse of turbidity is the task of pendulum in face of us.
The purpose of this utility model provides a kind of filter that is used to purify the low former water of turbidity.
The utility model adopts following measures in order to achieve the above object: it comprises filter body, be provided with filter plate in the filter, the filter body right-hand member is provided with hand-hole, the filter body left end is respectively equipped with the filtered water import up and down, the filtered water outlet, filtered water import and water distributor join, the filter body upper end is provided with hand-hole and exhaust outlet, filter body has saddle and drain, feature is that said water distributor is for waiting resistance slot slight drag water distributor, the filter plate filter opening is provided with the filter cap, is placed with three layers of quartz sand filter media on filter plate.
Advantage of the present utility model: adopt under this grating bed thickness condition, improve filtering velocity to V＜35m/h, (V can reach 8～15m/h) 2～4 times for conventional grating quartz sand filter media; The proportional filter tank volume that reduced of the raising of filtering velocity, promptly under same treatment water yield condition, this filter tank volume is conventional filter tank
～
, greatly dwindled floor space; The backwash rate of filter is 7L/Sm
2), reduce equipment dynamic, made layer of sand when flushing, can not cause random layer, reduced the generation of running the sand phenomenon, help equipment stable operation, nonuniformity coefficient is 1.6, less than traditional filter material (＜2), makes filtrate that bigger porosity be arranged, be beneficial to the cohesion and the flocculation of suspension, improve filtrate and contained dirty ability, reduced the backwash frequency, saved the backwash water yield and power consumption.Equipment on high filtering velocity, delivery turbidity still can＜3mg/l meets national drinking water standard.
Elaborate below in conjunction with accompanying drawing
Fig. 1 is the structure of filter schematic diagram
Fig. 2 is the cross section of filter.
Filter comprises
Filter body [3], be provided with filter plate [7] in the filter, the filter body right-hand member is provided with hand-hole [5], the filter body left end is respectively equipped with filtered water import [1] up and down, filtered water outlet [4], filtered water import and water distributor join, and the filter body upper end is provided with hand-hole [2] and exhaust outlet, filter body has saddle [6] and drain, and feature is that water distributor is to wait resistance slot slight drag water distributor.The filter plate filter opening is provided with the filter cap, and the material of filter cap is a nylon.On filter plate, be placed with three layers of quartz sand filter media.Three layers of quartz sand filter media on filter plate, being put, being respectively particle diameter from top to bottom is 2-3mm quartz sand 150-200mm, and particle diameter is 0.7-1.2mm quartz sand 150-200mm, and particle diameter is 0.45-0.6mm quartz sand 450-550mm.Perhaps being respectively particle diameter from top to bottom is 2-3mm quartz sand 150mm, and particle diameter is 0.7-1.2mm quartz sand 150mm, and particle diameter is 0.45-0.6mm quartz sand 500mm.During flushing, filter out the mouth of a river and change the flushing water inlet into, the filtered water inlet mouth changes the flushing pollution discharge outlet into.
