Abstract
The utility model relates to an improved net type filter which belongs to the improved net type filter for agricultural water saving irrigation system, comprising a shell provided with an intake pipe, an exhaust pipe and a drainage pipe and a filter screen arranged inside the shell, wherein a current guide plate is arranged inside the intake pipe on the shell; an impeller provided with a vane is arranged on the upper part of the shell; the height of the vane is compatible with that of the intake pipe; a filter screen brush near the surface of the filter screen is arranged on the vane; and brush hairs are arranged on the filter screen brush. When the utility model is used, a water pump does not need to stop running during the process of impurities cleaning, and water power is used to automatically removing impurities on the surface of the filter screen without need of manpower, thereby the uninterrupted irrigation can be realized, the time and labor consumed are lowered, the work efficiency is improved, and the structure is simple and the operation is convenient.
Description
Technical field: the utility model belongs to the improvement of the well strainer of using in the agricultural water-saving irrigation system, relates to a kind of improved well strainer.
Background technology: at present, the well strainer of using in agricultural water-saving irrigation system is installed in the stem of irrigation system more, its effect is the insoluble tangible impurity that removes in anhydrating, the water that assurance enters sprinkling irrigation, drip irrigation system is clean water, and makes water can flow out end-equipment in the irrigation system smoothly.But the water quality of farmland irrigation water is bad now, and insoluble tangible impurity is many, and all kinds of impurity often can accumulate on the filter screen, and in the course of time, the water that can enter filter screen just reduces gradually, and the hydraulic pressure that acts on simultaneously on the filter screen constantly increases.If untimely taking-up filter screen manually cleans, filter screen will be squeezed broken by hydraulic pressure, and impurity will cause great destruction and bring enormous economic loss if enters in the pipeline whole water-saving irrigation system.In order to prevent this situation, often termination of pumping is cleaned by artificial taking-up filter screen, not only increases the weight of personnel's workload, and frequent termination of pumping, turn on pump, will reduce the life-span of water pump, not only electricity wasting but also influence irrigation to crops.
Summary of the invention: the purpose of this utility model is to provide a kind of improved well strainer, it can remove all kinds of tangible impurity that covers on the filter screen effectively in the filter course of work, do not need termination of pumping, alleviate personnel's labour intensity greatly, do not influence irrigation crops.
The purpose of this utility model is achieved in that a kind of improved well strainer, it comprises the housing that is provided with water inlet pipe, outlet pipe and blow-off pipe and is installed in the interior filter screen of housing, be provided with the current deflecting plate in the water inlet pipe on the housing, the top of housing is provided with the vaned impeller of dressing, the height of blades height and water inlet pipe adapts, blade is provided with the filter screen brush near screen surface, and filter screen brushes and is provided with bristle.
When using the utility model, pull sidewall with being installed in current deflecting plate in the water inlet pipe to water inlet pipe, current impact impeller along certain angle to be made it to rotate, the rotation of impeller drives the filter screen brush that is installed on the blade and rotates, be arranged on bristle that filter screen brushes and scrub the surface of filter screen, cover all kinds of impurity of screen surface or being wrapped in filter screen brushes, otherwise by brush from screen surface, make the mesh of filter screen always keep unimpeded.After filter used a period of time, with regard to counter-rotation current deflecting plate, current promoted the impeller backward rotation, made that being wrapped in the impurity that filter screen brushes is peeled off.Open the blowoff valve at the blow-off pipe place that is arranged on the housing impurity in the filter is discharged, impurity is closed blowoff valve and is got final product after draining only.Owing in the utility model removal of contamination process, all do not need termination of pumping, therefore can realize uninterrupted irrigation, do not need manually to clean filter screen by the waterpower automatically clearing impurity, time saving and energy saving, improve work efficiency, and it is simple in structure, easy to operate.
Description of drawings: Fig. 1 looks cross-sectional view for master of the present utility model; Fig. 2 is the A-A profile among Fig. 1.
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing, a kind of improved well strainer, as shown in Figure 1, it comprises housing 8 and the filter screen 10 that is installed in the housing 8, be respectively arranged with water inlet pipe 7, outlet pipe 15 and blow-off pipe 13 on the housing 8, be provided with current deflecting plate 6 in the water inlet pipe 7, the rotation axle head of current deflecting plate 6 is fixedlyed connected with handle 5, turning handle 5 can drive the side that current deflecting plate 6 turns to water inlet pipe 7, makes to form angle between the blade 4 of water (flow) direction and impeller and promote the impeller rotation.The exit of outlet pipe 15 is provided with valve 14, and the exit of blow-off pipe 13 is provided with blowoff valve 12.The top of housing 8 is provided with seal cover 3, the following housing 8 of seal cover 3 is provided with bearing 1, cooperate the lower end of the axle of installing 2 that the impeller that blade 4 is housed is being set with bearing 1, the height of the height of blade 4 and water inlet pipe 7 is unanimous on the whole, blade 4 is provided with the filter screen brush 9 near filter screen 10 surfaces, and filter screen brush 9 is provided with bristle.As shown in Figure 1, the inside that is installed in the filter screen 10 in the housing 8 can also be provided with one deck filter screen 11, filter screen 11 adopts finer and closely woven material to make, and the filtration time that two-layer screen pack can prolong water is installed, and makes that the fine impurity in the current also can be filtered out completely.As shown in Figure 2, the shape of cross section that is arranged on the delivery port place of the water inlet pipe 7 on the housing 8 can be for tubaeform, also can be for fan-shaped, and like this, current can impact blade 4 with certain angle, thereby more effectively promote wheel rotation.As shown in Figure 2, the number that is installed in the filter screen brush 9 on the blade 4 can be the 4-8 root.
