Abstract
A kind of manual backwashing filter, is made up of blowdown assembly, intake antrum, intermediate cavity, filter chamber.Blowdown assembly comprises blow-off pipe, handle, capping and wastewater inlet, and blow-off pipe is passed by intake antrum center and arrives filter chamber top; Intermediate cavity is the hollow plum blossom column construction of symmetric arrays centered by blow-off pipe, is provided with drain outlet in intermediate cavity; Filter chamber is made up of shell and multiple filter core.During filter work, capping is in the centre position of two perforates in intake antrum bottom surface, and wastewater inlet is closed by intermediate cavity sidewall, and now source water enters filter core and filters; When impurities accumulation in filter core to water-in and water-out pressure differential reaches design higher limit, rotary handle, make capping close a perforate of intake antrum bottom surface, wastewater inlet is just communicated with drain outlet, and filter core is in backwash state.Compact conformation of the present invention, cost is low, and each filter core can be washed by independent back flushing, does not shut down blowdown, and less on system worked well impact, operating efficiency is high.
Description
Technical field
The invention belongs to water-treatment technology field, relate to water filtration device, be specifically related to a kind of manual backwashing filter.
Background technology
Filter is the most widely used a kind of filter plant of agriculture irrigation system and Treatment of Industrial Water.During current engineer applied, the mode mostly combined by multiple filter realizes the backwash of filter screen, connecting line and valve more, integrated model is comparatively loose, huge, and overall cost is high, and local head loss is larger, comparatively large on system worked well impact during backwash, operating efficiency is relatively low.
Summary of the invention
The object of the present invention is to provide a kind of compact conformation, be convenient to the filter of backwash.
The technical solution that the present invention takes is: a kind of manual backwashing filter, is made up of blowdown assembly, intake antrum, intermediate cavity, filter chamber.Described intake antrum is hollow cylinder, and intake antrum is provided with water inlet pipe, and water inlet pipe arranges inlet gage, and the inlet communication of multiple aperture by intermediate cavity and filter core is offered in intake antrum bottom surface, described intermediate cavity is between intake antrum and filter chamber, cylinder centered by the center of intermediate cavity, centrally cylindrical center is that even circumferential distributes the interface channel of multiple circular tube shaped, the inwall of central cylinder and blow-off pipe outer wall close contact, multiple cylinders of the peripheral quincunx symmetric arrays of intermediate cavity are the interface channels of intake antrum and filter core, the end face of interface channel is communicated with intake antrum respectively, the bottom surface of interface channel respectively with the inlet communication of filter core, interface channel and perforate being communicated with respectively on the wall at central cylinder line of centres place, as drain outlet, described filter chamber is made up of cylinder blanket and multiple cylindrical filter cartridge, and outer casing top surface opens the import of some circular holes as filter core, and shell is provided with outlet pipe, outlet pipe sets out water pressure table, and filter core tail end is closed by enclosure bottom, described blowdown assembly comprises blow-off pipe, handle, capping and wastewater inlet, described blow-off pipe is outside from intake antrum, filter chamber end face is arrived through its end face and bottom surface by intake antrum center, one end that blow-off pipe contacts with filter chamber end face is blind end, blow-off pipe is positioned at the pipeline section lateral opening hole of intermediate cavity as wastewater inlet, blow-off pipe is arranged blowdown hydraulic gauge, described handle is positioned on the blow-off pipe of intake antrum outside, capping is positioned on the blow-off pipe of intake antrum inside, and with intake antrum bottom surface close contact, capping is circular slab, its diameter is greater than the internal diameter of interface channel.
Described reverse flushing filter screen filter, the quantity of intake antrum bottom surface perforate, the quantity of intermediate cavity surrounding cylindrical body are identical with the quantity of filter core, comparatively reasonable when quantity is set to 2-12.
Described reverse flushing filter screen filter, turning handle can make blowdown component integration rotate along central shaft.Capping is consistent with the direction of wastewater inlet, axial centre section overlaps, when capping rotates the position to intake antrum bottom surface in the middle of two perforates, filter core import is full-gear, and wastewater inlet is just closed by the inwall of the central cylinder of intermediate cavity, drain outlet is closed, and filter core is all in filtration condition.When the central rotation of capping is to center superposition with the perforate in intake antrum bottom surface, this place's filter core import is capped to be closed, and wastewater inlet just overlaps with the drain outlet at this place, and drain outlet is opened, and filter core is in backwash state herein.During filter work, all filter cores are all in filtration condition.During Filter Back Washing, only have a filter core to be in backwash state, other filter core is then in filtration condition.
Described reverse flushing filter screen filter, water inlet pipe and outlet pipe have four kinds of assembling schemes: the first scheme, and water inlet pipe is positioned on the side surface circumference of intake antrum, and outlet pipe is positioned on the side surface circumference of shell.First scheme, water inlet pipe is positioned on the side surface circumference of intake antrum, and outlet pipe is positioned at the bottom surface of shell.The third scheme water inlet pipe is positioned at the end face of intake antrum, and outlet pipe is positioned at the bottom surface of shell.4th kind of scheme, water inlet pipe is positioned at the end face of intake antrum, and outlet pipe is positioned on the side surface circumference of shell.When building backwash filter, four kinds of schemes can optional one.
Described reverse flushing filter screen filter, during work, the capping of blowdown assembly is in the position in the middle of the perforate of two, intake antrum bottom surface, wastewater inlet then mediates the inwall place of central cylinder in chamber, just in time make filter core import be full-gear, drain outlet is closed state, and now source water enters filter core inside and filters, clear water after filtration comes together between filter core and shell, is exported by outlet pipe.Along with the increase of filtration time, the accumulation gradually of screen wall and filter core inside, pressure differential into water and water outlet is increased gradually, when pressure reduction reaches design higher limit, turning handle, make the center superposition of the cap central of filter assemblies and a perforate of intake antrum bottom surface, then this place's filter core import is capped closes, wastewater inlet just overlaps with the drain outlet at this place, drain outlet is opened, clear water ecto-entad between filter core and shell enters filter core, the impurity accumulated in screen wall and filter screen is rinsed and enters blow-off pipe discharge, filter core is in backwash state herein.Along with filter screen cleans up gradually, in blow-off pipe, flow increase, pressure increase, when blowdown overpressure reach design the upper limit or observe blowdown in-pipe flow impurity less time, turning handle, carry out the backwash of next filter screen, until all filter screens are rinsed well, blowdown assembly rotates to original position, and filter core full recovery is to duty.
The beneficial effect of the present invention's structure: the present invention passes through the ingehious design of blowdown assembly and intermediate cavity; make multiple worry cores of filter, blowdown apparatus and the compact combination of intake antrum; filter general structure is simple; filter light and handy with the conversion of backwash, convenient, can not shut down and backwash and independent blowdown are carried out to filter core.Relative to the integrated mode of multiple filter, connecting pipe, pipe fitting and valve are few, and the loss of flood peak is little, and overall cost is low, and less on system worked well impact, operating efficiency is high.
