Description
Technical field
The utility model belongs to the filtration unit, particularly bar shaped desilting filtering basin of farmland water conservancy spray drip irrigation project water.
Background technology
Along with agricultural and industrial expansion, water resources is in short supply day by day, and development high-efficiency water-saving technology is extremely urgent.Water source form commonly used is a underground water in the agricultural high-effiency water saving.At present, the groundwater mining phenomenon is serious, greatly develops the guarantee that will become agricultural sustainable development with surface water as the high-efficiency water-saving technology at water source.The traditional spray of drawing surface water, drip irrigation system need drop into a large amount of funds the silt in the surface water is handled, thereby have seriously restricted the promotion and application of advanced persons' such as spray, drip irrigation high-efficiency water-saving technology.
At present, be that the high-efficiency water-saving engineering measure at water source is with the surface water: after the former surface water diversion at first through traditional rectangular sedimentation tank precipitation; Post precipitation water enters the filtration that also needs before spray, the drip irrigation pipe network system again through sandstone strainer and screen filter, screen filter and sandstone strainer cost are higher, also need after 1-2 the rotation flow its back flushing, What is more, and a rotation flow is not just finished and must be safeguarded back flushing to it, and this has brought very big inconvenience for the operational management of high-efficiency water-saving system.
Traditional sandstone strainer be behind pump, high-pressure system work, after in a single day strainer was blocked, system efficiency was low.Should irritate a circulation in three days, often all can not irritate in seven days, have a strong impact on the promotion and application of high-efficiency water-saving technology.
The utility model content
The purpose of this utility model is to provide a kind of bar shaped desilting filtering basin, and it is rational in infrastructure, drainage efficient height, and cost is low, and operational management is convenient, and working cost is low, dependable performance, system failure rate is low, long service life.
The purpose of this utility model is achieved in that a kind of bar shaped desilting filtering basin, inlet channel is connecting the bar shaped sedimentation basin, connecting clean water basin at bar shaped settling pit rear portion, upper lateral in the bar shaped sedimentation basin is being provided with the unsettled partition wall that connects the both sides pool wall, the pool wall at unsettled partition wall and its rear portion constitutes unsettled filtration chamber, on the bottom surface of unsettled filtration chamber, filter screen is being set, on the locular wall of unsettled filtration chamber, be communicated with clean water basin by the through hole that is provided with, pump line is being set in clean water basin, connecting blow-off pipe below bar shaped sedimentation basin afterbody, the other end of blow-off pipe is connecting the sewage well that residual sea water pump is housed.
In the utility model when work,, surface water enters the bar shaped settling tank by inlet channel, carries out preliminary sedimentation, make particle diameter husky in the surface water greater than the suspended particle of 1mm under the effect of self gravitation with water sepn.The filter screen that water behind the preliminary sedimentation is provided with on bottom surface, unsettled filtration chamber, with particle diameter in the water less than the suspended particle of 1mm again through the filter screen of regulation order number, water after filtering overflows in the clean water basin from the through hole that unsettled filtration chamber locular wall is provided with.Water pump pumps into drip irrigation system by pump line with the clear water in the clean water basin and carries out drip irrigation.When need getting rid of long-pending husky in the sedimentation basin, close the inlet gate on the inlet channel earlier, open residual sea water pump, carry out blowdown.Because bar shaped sedimentation basin bottom surface Parallel to the flow direction has certain longitudinal gradient, the below of bar shaped sedimentation basin afterbody is connecting blow-off pipe, the other end of blow-off pipe is connecting the sewage well that residual sea water pump is housed, and opens residual sea water pump the water level in the bar shaped sedimentation basin is reduced to below the filter screen rapidly.At this moment manually filter screen is washed, only need the short time just filter screen is rinsed well and the silt emptying in the bar shaped sedimentation basin with water blast gun.
The utility model is because the flow velocity of net filtration water is very little after filtration, filter screen low pressure approximate do not have press to such an extent that work under the condition.Filter structure is simple, and the probability of damage is very little, can reduce the drainage cost effectively.The utility model is rational in infrastructure, drainage efficient height, and cost is low, and the drainage effect is visual, and operational management is convenient, and working cost is low, dependable performance, system failure rate is low, long service life.
