Description

Farmland drip irrigation river water filter

Technical field: the utility model relates to a kind of farmland drip irrigation auxiliary facility, especially a kind of water filter.

Background technique: trickle irrigation is the water that will have certain pressure, through pipe network and outlet conduit (drip irrigation zone) or drop after filtering A kind of head irrigation method that is slow and equably instilling soil near plant root in the form of water droplet.Since it is to water quality requirement It is higher, it is mostly used underground water and surface water is abandoned.This phenomenon in the case where trickle irrigation is widely applied state first is that cause underground water super It adopts, second is that the technical issues of not resolving the surface water for providing qualified water.There is a kind of facility for being called Overwater-floating to swim in On the water surface in river or lake, river water takes supply drip irrigation system away by water pump after its bottom surface strainer filtering.But itself the problem is that Water purification is filtered take away after, the rubbish dirt of the external water surface is increasing in filter screen ambient density, block strainer, be subsequent mistake Leaching water causes difficulty.

Summary of the invention: the purpose of this utility model is to design a kind of farmland drip irrigation river water filter, places it river Bank, is handled after drawing drainage in river water, does not influence the normal water flow in river.And it continuous multi-stage can fetch water on river Purification.Overcome taking a little for the prior art.Purpose of the utility model is realized as follows: farmland drip irrigation river water filter, It is made of filter housings, strainer and water impurity cleaning mechanism.Circle tube leaching net is mounted among the filter housings of cuboid, The water purification by strainer filtering is received in closed filter housings.Water impurity cleaning mechanism includes what filter housings right end connected Heavy seeds settling tank；It is equipped with the drainage conveyer belt for separating frivolous impurity below the water outlet of settling tank, there is rhone further below. There is water pump in the water purification in filter head housings body, drainpipe connects trickle irrigation water system.Water impurity cleaning mechanism further include with The clear net water pipe of pump drain pipe connection, is mounted on above circle tube leaching net；And cylindrical shape is filtered in sewage pipe, water outlet The floating impurity of the flowing water water surface to be filtered rushes at outlet in netting.

Rotation is driven by motor in drainage for circle tube leaching net.

The settling tank of filter housings right end connection has slag-drip opening.

Drainage conveyer belt below the water outlet of settling tank is made of a kind of Web materials, floats to the side feed water surface Floating object.

Rhone below the water outlet of settling tank, water discharging direction is adjustable, can be by scavenger precipitation object and floating material The water of impurity sends river back to, or separately makees surface irrigation and other purposes.

The clear net water pipe connected with the drainpipe of water pump in filter head housings body is mounted on the upper of circle tube leaching net whole length There is a fountain head for clearing the impurity of viscous clothes in reason strainer in side against circle tube leaching net on one side.

The water outlet of the sewage pipe connected with the drainpipe of water pump in filter head housings body is located at the water surface in circle tube leaching net Height, against direction from inlet water to outlet water, to be higher than the high pressure water flow of river flow velocity for the drift of the circle tube leaching net water surface Floating impurity goes out strainer.

Farmland drip irrigation is placed in the bank in river with river water filter, and part river water is introduced farmland drop by diversion channel It fills and uses river water filter.According to farmland drip irrigation water position and water consumption, suitable distance is determined, installation next stage farmland drip irrigation is used River water filter.

Farmland drip irrigation is that it is placed in river bank with the beneficial effect of river water filter, and filtering is drawn from river water Purified treatment is carried out after water, does not influence the normal water flow in river.It can also the continuous multi-stage water intaking purification on river.Than with underground water at This reduction.It can guarantee that farmland drip irrigation system has continuous, sufficient, the satisfactory water consumption of water quality.

Detailed description of the invention: Fig. 1 is the structural schematic diagram of farmland drip irrigation river water filter.Fig. 2 is farmland drip irrigation river water mistake Filter places schematic diagram in river.

Specific embodiment: it is described further with reference to the accompanying drawing.

As shown in Figure 1, farmland drip irrigation river water filter, is made of filter housings, strainer and water impurity cleaning mechanism. Circle tube leaching net 7 is mounted on the upper middle position of the filter housings 14 of cuboid, and circle tube leaching net is in drainage by motor 5 It is driven and is rotated by gear 6.The river water being intercepted is flowed through from cylinder leaching net, and the water purification 13 of strainer filtering is stored in below strainer Filter housings 14 cavity in.The mesh of circle tube leaching net should guarantee that the water quality for meeting drip irrigation system is wanted in 60-100 mesh It asks.There is water pump 2 in the water purification in filter head housings body, drainpipe 1 connects trickle irrigation water system.Water impurity cleaning mechanism includes The clear net water pipe 4 connecting with diving pump drain pipe is mounted on the top of circle tube leaching net whole length, the opposite circle of clear net water pipe The fountain head for having the impurity for clearing the viscous clothes of reason strainer inner wall on one side of tubular strainer, removes the tamper of strainer, always in time Guarantee the transparent performance of strainer.

Water impurity cleaning mechanism further includes the sewage pipe 3 connecting with diving pump drain pipe, the water outlet position of sewage pipe It will to be higher than the high pressure water flow of river flow velocity against direction from inlet water to outlet water in the height of the water surface in circle tube leaching net The floating impurity of the water surface goes out strainer in circle tube leaching net.

Water impurity cleaning mechanism further includes the heavy seeds settling tank 8 of filter housings right end connection, the section ratio of settling tank The section of circle tube leaching net increases, and flowing water speed slows down, and the silt and weight in water sink to bottom, can be periodically from sewage draining exit 12 Discharge.A kind of drainage conveyer belt 10 of light impurity of separation made of Web materials is equipped with below the water outlet 9 of settling tank, The floating on water impurity 16 being discharged from water outlet is filtered out, and conveys and is concentrated to side.There is rhone 11 further below, rhone Water discharging direction is adjustable, can send the water of scavenger precipitation object and floating material impurity back to river, or separately make surface irrigation and other It arranges.

As shown in Fig. 2, farmland drip irrigation is placed in the bank in river 15 with river water filter, by diversion channel 17 by part River water introduces in circle tube leaching net of the farmland drip irrigation with river water filter；According to farmland drip irrigation water position and water consumption, select Spacing installs multistage farmland drip irrigation river water filter.It creates conditions to be widely applied drip irrigation technique.
