Chinese patent CN 2593878Y discloses a kind of horizontal backwash sandrock filter, it comprises tank body, water inlet pipe, outlet pipe, sewage backwash pipe, filter tank internal partition, dress sand hole, quartz sand is housed in the filter tank, the outlet pipe front end is provided with filter core cylinder, and the filter core cylinder periphery is provided with the several holes hole, is equipped with cap shape filter core on each hole, the other end of filter core cylinder stretches out outside the filter tank, tank body is provided with the filter core wound packages and gets mouth, and the filter core wound packages is got mouth and is provided with closure fange, and bar-shaped filter core is arranged in the filter core cylinder; Filter core cylinder is a more piece shape structure, adopts rim of the mouth socket or thread connection between each joint.Shortcoming is: filter core cylinder adopts more piece shape structure, and with rim of the mouth socket or spiral marking connection, complex structure is difficult to manufacturing; Filter core cylinder is rounded, installs when emitting the shape filter core on the filter core cylinder, and emitting shape filter core bottom surface and filter core cylinder contact-making surface is that the plane contacts with cambered surface, and bonded area is little, and fastness is poor, and service life is short; The tank body lower end lacks drainage arrangement, and surplus water is difficult for draining in the tank body, the screw thread that the links more piece shape filter core cylinder damage of easily getting rusty, and maintenance cost is higher; The filter core cylinder cross-sectional area is little, and backwash effect is poor; Quartz sand will be discharged during maintenance, filter core cylinder could be taken out, the tank body lower end lacks sand removing device, takes out the quartz sand inconvenience during maintenance.
Summary of the invention
It is a kind of simple in structure that the utility model is to provide, and is convenient to make long service life, the horizontal backwash sandrock filter that backwash effect is good.
The technical scheme that the utility model technical solution problem is taked is: a kind of horizontal backwash sandrock filter, comprise tank body, water inlet pipe, outlet pipe, sewage backwash pipe, dividing plate, dress sand hole, tank interior is provided with filter core plate with holes, the filter core plate is provided with filter, closed cavity is formed at filter core plate and inner tank wall bottom, and this closed cavity communicates with described outlet pipe.
Above-mentioned horizontal backwash sandrock filter, filter are cap shape filter core, and cap shape filter core is located on each hole.
Above-mentioned horizontal backwash sandrock filter, filter also can be filter screen, filter screen is in the described closed cavity outside.
Above-mentioned horizontal backwash sandrock filter, filter core plate both sides directly are connected with tank body, and two ends are provided with the water shutoff plate in addition, and described closed cavity is formed at filter core plate and water shutoff plate and inner tank wall bottom.
Above-mentioned horizontal backwash sandrock filter, water shutoff plate also can be the described filter core plate that is provided with filter, can increase the filtration yield of water like this, increase work efficiency.
Above-mentioned horizontal backwash sandrock filter, tank body are provided with the filter dress and get mouth, and dress is got the sealing blind plate on the mouth, between the sealing blind plate sealing gasket are housed, and seal, and take away blind plate during maintenance, can get mouthful described filter of replacing from dress easily.
Above-mentioned horizontal backwash sandrock filter, water inlet pipe bottom in the tank body is provided with branch water plate, divide water plate upper surface curved, current are through undue water plate, be evenly dispersed, reduced the impact of current to the quartz sand in the tank body, make quartz sand be dispersed in uniformly the filter core plate around, make filter effect better.
Above-mentioned horizontal backwash sandrock filter, the tank body upper end is provided with steam vent, can discharge the air in the tank body during water inlet, reduces the resistance of current, keeps water inlet unobstructed.
Above-mentioned horizontal backwash sandrock filter, the tank body lower end is provided with the draining ball valve, and this draining ball valve communicates with described closed cavity, when finish irrigation season, can be used to drain remaining water in the tank body, reduces the corrosion of surplus water to tank body, prolongs its service life.
Above-mentioned horizontal backwash sandrock filter, the tank body lower end is provided with clearance hole, can easily quartz sand be discharged during maintenance, is convenient to maintenance.
The utility model adopts tabular filter element device, and is simple in structure, is easy to make; Filter core plate and filter adopt plane and plane contact, and contact area is big, and long service life is installed firmly; Filter can be got mouth by dress and be convenient for changing; Divide the water plate that current are evenly distributed, reduce impact, make quartz sand be evenly distributed on the filter core panel area quartz sand in the tank body, good filtration effect, the cross-sectional area of filter core plate is big, and backwash effect is good, tank body is provided with the draining ball valve, can drain surplus water in the filter tank, reduce corrosion, prolong the service life of tank body, cost is lower, tank body is provided with clearance hole, can conveniently discharge quartz sand, is convenient to maintenance.
