Abstract
The utility model relates to a sand filter for irrigation. The sand filter is a cavity tank; the upper part of the sand filter is a cylindrical separation cavity; the lower part of the sand filter is a reversely conical collection cavity; the collection cavity is communicated with a water inlet in the tangent direction of the outer circumferential wall of the separation cavity; a top cover covers an upper port of the separation cavity; a water outlet pipe is inserted into the center of the top cover; the upper part of the water outlet pipe extends out of the top cover, and the lower part of the water outlet pipe extends into the separation cavity; a lower port is formed in the separation cavity; and a filter flow guide net is arranged at the lower port of the water outlet pipe. By a centrifugal theory, relatively large-granule sand is separated; floating substances with low density such as waterweeds and partial small-granule sand, which cannot be separated, are isolated by a filter net, so that purity of water flow can be effectively guaranteed; and sediment is prevented from entering an irrigation zone.
Description
Technical field
The utility model relates to a kind of filter, relates in particular to a kind of irrigation sandrock filter.
Background technology
Agricultural drop irrigation has been the agricultural irrigation technology that China popularizes, and the effect quality of drip irrigation has direct relation with drip irrigation.Be less floating thing and the part silt clogging drip irrigation band of pasture and water isodensity in the anti-sealing, before current enter the drip irrigation zone, will carry out the detached job of current and silt.The sandrock filter of Shi Yonging adopts centrifugal principle that sandstone is separated more now, but owing to be subjected to the influence of inflow size, make that less floating thing and the tiny grit of part of some pasture and water isodensity can't effectively break away from the current, cause the drip irrigation zone clogging still to happen occasionally.
Summary of the invention
The purpose of this utility model is to propose a kind of simple in structure, effectively the irrigation sandrock filter of grit in the separated flow.
The purpose of this utility model is achieved in that irrigating with sandrock filter is a cavity jar, its top is columniform disengagement chamber, the bottom is the collecting chamber of back taper, tangential direction at the disengagement chamber outer circle wall is communicated with water inlet, upper port at disengagement chamber is stamped top cover, and the top cover center is inserted with outlet pipe, and top cover is stretched out on outlet pipe top, disengagement chamber is stretched in the bottom, and lower port is positioned at disengagement chamber.The water conservancy diversion net is filtered in installing at outlet pipe lower port place.
The utility model is after the grit that utilizes centrifugal principle with larger particles breaks away from, and the floating thing that the pasture and water isodensity of utilizing screen pack to break away from is less and part granule grit are isolated, and can effectively ensure the pure of current, prevent that silt from entering the drip irrigation zone.
Description of drawings: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 irrigates to use the sandrock filter structural representation.
Legend: 1, water inlet pipe, 2, top cover, 3, outlet pipe, 4, disengagement chamber, 5, filter the water conservancy diversion net, 6, collecting chamber.
The specific embodiment:
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, irrigating with sandrock filter is a cavity jar, and its top is columniform disengagement chamber 4, and the bottom is the collecting chamber 6 of back taper, and sediment ejection opening is offered on collecting chamber 6 tops.Be communicated with water inlet pipe 1 in the tangential direction of disengagement chamber 4 outer circle walls, be stamped top cover 2 in the upper port of disengagement chamber 4, top cover 2 centers are inserted with outlet pipe 3, and top cover 2 is stretched out on outlet pipe 3 tops, and disengagement chamber 4 is stretched in the bottom, and lower port is positioned at disengagement chamber 4.Water conservancy diversion net 5 is filtered in installing at outlet pipe 3 lower port places, and filtering water conservancy diversion net 5 sizing grids is 2 ~ 80mm, and concrete size is determined according to filter medium.
After utilizing the grit disengaging of centrifugal principle with larger particles, less floating thing and the part granule grit of pasture and water isodensity that utilizes filtration water conservancy diversion net 5 to break away from isolated, and the sedimentation after the disengaging is discharged by sediment ejection opening in collecting chamber 6.
Claims (2)
1. irrigation sandrock filter, it is a cavity jar, it is characterized in that: its top is columniform disengagement chamber, and the bottom is the collecting chamber of back taper, at the tangential direction connection water inlet of disengagement chamber outer circle wall, upper port at disengagement chamber is stamped top cover, the top cover center is inserted with outlet pipe, and top cover is stretched out on outlet pipe top, and disengagement chamber is stretched in the bottom, lower port is positioned at disengagement chamber, and the water conservancy diversion net is filtered in installing at outlet pipe lower port place.
