Simple and high-efficiency quartz sand filter

Abstract

The invention relates to the technical field of water purification accessory device, and in particular, relates to a simple and high-efficiency quartz sand filter; a quartz sand filter layer can be swashed without stopping a machine, the operation is simple, and the working efficiency and practicability are improved; moreover, the quartz sand filter layer can be fully utilized, and the use reliability is improved. The quartz sand filter includes a filter box, four groups of support legs, a filter screen, a quartz sand filter layer, a liquid inlet pipe, a liquid outlet pipe, a motor, a speed reducer, a sand washing box, a sand lifting pipe and a swashing pump; the interior of the filter box is provided with a working chamber; the sand washing box and the sand lifting pipe are both located in the working chamber; the interior of the sand washing box is provided with a placement chamber, and two groups of swashing pipes are arranged at the bottom of the placement chamber; the top ends ofthe two groups of swashing pipes are provided with a plurality of swashing nozzles in a communication manner, and the outer side of the bottom end of the sand washing box is provided with a pluralityof sand falling ports; the top end of the filter box is provided with a fixed seat. The quartz sand filter includes a rotating shaft, a screw conveying blade, a sewage drain pipe, a bearing seat, three groups of arc scraping plates and a ball bearing.

Description

Technical field [0001] The invention relates to the technical field of water purification accessory devices, in particular to a simple and efficient quartz sand filter. Background technique [0002] As we all know, the quartz sand filter uses quartz sand as the filter medium. Under a certain pressure, the water with higher turbidity is filtered through a certain thickness of granular or non-granular quartz sand to effectively intercept and remove suspended solids and organic matter in the water. , Colloidal particles, microorganisms, chlorine, smell and some heavy metal ions, etc., and finally achieve the effect of reducing water turbidity and purifying water quality. It is a high-efficiency filtration equipment in the fields of reclaimed water reuse and industrial wastewater removal. Widely used; the existing quartz sand filter includes a filter box and four sets of legs. The tops of the four sets of legs are welded and fixed to the left front, right front, left rear and right r...

[0002] As we all know, the quartz sand filter uses quartz sand as the filter medium. Under a certain pressure, the water with high turbidity is filtered through a certain thickness of granular or non-granular quartz sand to effectively intercept and remove suspended solids and organic matter in the water. , colloid particles, microorganisms, chlorine, smell and some heavy metal ions, etc., and finally achieve the effect of reducing water turbidity and purifying water quality. Widely used; the existing quartz sand filter includes a filter box and four sets of legs, the tops of the four sets of legs are respectively welded and fixed to the left front side, right front side, left rear side and right rear side of the bottom of the filter box, and the filter box There is a working chamber inside, and a horizontal filter screen is set at the bottom of the working chamber. The top of the filter screen is equipped with a quartz sand filter layer, and the left end of the filter box is connected with a liquid inlet pipe, a backwash water inlet pipe and a backwash outlet. Water pipes, and on-off water valves are set at the backwash water inlet pipe and backwash water outlet pipe, and the bottom of the filter box is connected with a liquid outlet pipe; when the existing quartz sand filter is used, the waste water is introduced from the liquid inlet pipe Into the working chamber, the scum and impurities in the wastewater are filtered through the quartz sand filter layer, and the filtered water is exported from the outlet pipe. When the quartz sand filter layer needs to be cleaned, it is necessary to stop the machine and then flush it through the backwash water inlet pipe. The quartz sand filter layer is flushed with clean water, and the waste liquid from the flushing is discharged from the backwash drain pipe; it is found in the use of the existing quartz sand filter that it needs to be shut down when flushing the quartz sand filter layer, which is cumbersome to operate and affects the filtration of waste water The work efficiency is low, resulting in low practicability; and the top of the quartz sand filter layer is mainly used for sewage filtration, and the bottom of the quartz sand filter layer is not fully utilized, resulting in low reliability
