Definitions
- This Utility Model refers to an improved sand filter for water treatment plants, which can be used in sewage treatment plants of the type installed in swimming pools, which is equipped with a sand extraction system by means of a water drive.
- Chemical means consist of the use of agents, such as chlorine, for the elimination of microorganisms.
- the mechanical means consist of filtering the water to remove impurities in suspension.
- filters being some of the type that consist of a tank full of siliceous sand, through which the water is circulated, being retained in the sand particles larger than that of the spaces that They are among the grains of it.
- the water intake in the pool is carried out at points located, both at the surface level, and at the bottom, and this is driven by a pump and driven by pipes towards the inside of the filter, discharging through nozzles located above, and being collected by a lower return pipeline that sends it, once clean, to the pool, where it flows in the form of jets through impellers, cooperating in the dragging of impurities to The collection points.
- the filter of the invention by its constitution and use, provides an effective means for extracting the sand from the filter, solving the problems described.
- the filter is constituted by a tank of material suitable to withstand the operating conditions, inside which the suction and return water pipes of the pool access.
- the suction pipe ends in a set of diffusers arranged superiorly, and the return pipe forms a set of manifolds located in the part lower, star-shaped, whose walls are provided with pores of diameter smaller than the size of the grain of the sand.
- Both the suction pipe and the return pipe are provided with two water flow cutting devices, such as stopcocks.
- the filter has a sand emptying tube, one of whose ends ends in the inner and lower part of the tank, between the return manifolds, the other end accessing the outside thereof, preferably from its upper side part, where it presents a cover or device for cutting the flow of water, which will be closed whenever no sand emptying works are carried out.
- the inner end of the tube reservoir will have a suitable shape to optimize the emptying of the sand, being able to have nozzles or other accessories for this purpose.
- the selector valve is placed in the washing position, whereby the flow of water through the inside of the filter is reversed, the * * suction pipe flow cutter is closed and the lid is opened of the sand drain tube.
- the water propelled by the pump reaches the tank through the collectors of the return pipe, and goes outside through the sand draining tube, dragging it outwards, draining it.
- a pipe to a collection point, preferably a filter bag that will retain the sand, allowing the water to pass, which can be recovered.
- the filter can have all the usual elements, such as the manometer, drain caps, etc.
- Figure 1 shows a diagram of the operation of a treatment plant provided with the filter of the invention.
- Figure 2 shows a section of the filter of the invention.
- the filter 1 of the invention is constituted by a tank 2 filled with siliceous sand, which retains the impurities, not shown, of the water 4 of a pool
- This water is conducted by means of pipes 10 to a filter 11 of larger particles and then to the filter 1 itself.
- selector valve 15 By means of a selector valve 15, it can be reversed in the direction of water circulation for the filter washing, sucking water through the impellers and evacuating the water from cleaning to a drain 16, avoiding its return to the pool.
- a stopcock 17 located in the suction pipe 17a is closed, the outer cover 18 of the sand emptying tube 19 is opened, and the water flow is reversed by the selector valve 15.
- the water is driven by the pump and enters the tank through the collectors 13, leaving the drain tube and dragging the sand in its path.
- This operation leaves a small residual amount of sand to be emptied, which can be rushed by opening the stopcock 17 and closing another stopcock 20 located in the return conduit 20 a, keeping the lid 18 open, and operating the selector valve 15 to Let water circulate directly.
- a pipeline At the outlet of the drain tube, a pipeline, not shown, can be arranged at a collection point, with a filter bag that retains the sand and allows the water to pass, which can be recovered.
