Abstract
The invention discloses a full-automatic back washing filter. A filter medium inlet is arranged at the lower part of a shell, and a filter medium outlet is arranged at the upper part of the shell; a drain outlet is arranged at the bottom of the shell; multiple groups of filter cores are arranged in the shell; an electric rotary valve is arranged in the shell; a back washing outlet channel communicated with a filter core is arranged at the lower part of the electric rotary valve, a back washing inlet channel is arranged at the upper part of the electric rotary valve, and the back washing inlet channel is communicated with the same filter core communicated with the back washing outlet channel; and the valve core of the electric rotary valve is arranged in a valve body communicated with an air storage chamber in which compressed air is stored. The full-automatic back washing filter of the invention has reasonable structure, realizes full-automatic operation, realizes unmanned supervision of marine engine rooms, has sufficient filter capacity, can continuously work, can automatically clean and filter impurities, can ensure stable system pressure and can be conveniently disassembled and maintained; and the filter core has high strength and long service life.
Description
Technical field:
The present invention relates to a kind of backwash filter.
Background technology:
Existing filter, general a plurality of filters are worked simultaneously or are carried out backwash simultaneously, when backwash, can not work, and influence the progress of work and efficient.
Summary of the invention:
The object of the present invention is to provide a kind of rational in infrastructure, the full-automatic back washing filter of favorable working performance.
Technical solution of the present invention is:
A kind of full-automatic back washing filter comprises housing, it is characterized in that: lower housing portion is provided with the filter medium import; Housing top is provided with the filter medium outlet, and sewage draining exit is arranged on housing bottom, and many group filter cores are set in the housing; Each filter core is arranged in the filter chamber, adorns electronic rotary valve in the housing, and electronic rotary valve bottom is provided with the backwash flow pass that communicates with a filter core; Electronic rotary valve top is provided with the backwash admission passage; And backwash admission passage and the same filter core that communicates with the backwash flow pass communicate, and electronic rotary valve upper end is provided with and contains compressed-air actuated air storage chamber, between electronic rotary valve and air storage chamber, are provided with the guiding valve that the control air storage chamber communicates with electronic rotary valve.
On rotary valve, be provided with the oil filler point that filter chamber is carried out fluid infusion.
The present invention is rational in infrastructure, realizes full automatic working, realizes the watercraft engine room no supervision; Have enough filter capacities, continuous operation, cleaning and filtering impurity automatically; Filer element strength is high, long service life; The assurance system pressure is stable, dismantles easy to maintenance.
Description of drawings:
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the configuration diagram of one embodiment of the invention.
Fig. 2 is the backwash state diagram.
The specific embodiment:
A kind of full-automatic back washing filter comprises housing 1, and lower housing portion is provided with filter medium import 2; Housing top is provided with filter medium outlet 3; Sewage draining exit 4 is arranged on housing bottom, and many group filter cores 5 are set in the housing, and each filter core is arranged in the filter chamber; Adorn electronic rotary valve 6 in the housing; Electronic rotary valve bottom is provided with the backwash flow pass 7 communicate with a filter core, and electronic rotary valve top is provided with backwash admission passage 8, and backwash admission passage and the same filter core that communicates with the backwash flow pass communicate; Electronic rotary valve 6 upper ends are provided with and contain compressed-air actuated air storage chamber 10, between electronic rotary valve 6 and air storage chamber 10, are provided with the guiding valve 9 that the control air storage chamber communicates with electronic rotary valve.On rotary valve, be provided with the oil filler point 11 that filter chamber is carried out fluid infusion.
Operation principle of the present invention is: filter liquide gets into import 2, flows into each independent filter chamber, and wherein the impurity greater than the regulation filtering accuracy is detained by filter core, and the clean liquid after the filtration flows out from exporting 3.
Increase along with the filter working time; Increasing impurity is trapped on the filter core; The pressure differential that causes importing and exporting two ends constantly rises, and when pressure reached setting value, rotary valve forwarded on the filter chamber position that needs flushing from subsequent use filter chamber; Clean filter core in the subsequent use filter chamber is participated in filtration, causes filter pressure reduction to descend at once.Rotary valve is opened blowoff valve after forwarding the filter chamber that needs flushing to, and the control air emptying makes guiding valve 9 move upward simultaneously simultaneously, and the compressed air in the air storage chamber impels the liquid reverse flow in the filter chamber to cross filter core, and the impurity that is bonded on the filter screen is rinsed out.Backwash is closed sewage draining exit after accomplishing, and control air gets into, and guiding valve is moved down, and seals the compressed air in the air storage chamber, and the filter chamber number of times of warp flushing and emptying carries out fluid infusion through the oil filler point on the rotary valve 11, and the air in the filter chamber can be discharged through exhaust apparatus.
Claims (2)
