The paper pulp waste water filter screen type automatic reverse cleaning filter has the advantages that the automatic reverse cleaning filter is compact in integral structure, high in operation efficiency and fine in treatment effect, adopts hydraulic power as power, saves cost, and reduces energy consumption.
Description
Technical field
The utility model relates to a kind of filter technology, the automatic anti-filter rinsed of particularly a kind of paper pulp wastewater filter net type.
Background technology
At present, the net type filter of using on the market adopts filter screen to come impurity in the pulp treatment waste water, time to grow will be in the surface mount of filter screen a lot of residues mostly, to the filter screen build-up of pressure, when serious even can destroy filter screen.Prior art is being done a lot of improvement aspect the cleaning of filter screen, such as purging system is installed in filter, still the purging system of installing mostly adopts electrical equipment control, expends very much the energy and is unfavorable for energy-conservation production.
Summary of the invention
The purpose of this utility model is in order to address the above problem, to have designed the automatic anti-filter rinsed of a kind of paper pulp wastewater filter net type.
Realize that the above-mentioned purpose the technical solution of the utility model is, the automatic anti-filter rinsed of a kind of paper pulp wastewater filter net type, comprise housing, screen pack, dividing plate and purging system, in the horizontal insertion housing of dividing plate, make the top of housing form filtering area, lower part of frame forms the blowdown district, purging system is fixedly mounted on the bottom in blowdown district, the one end is upward through dividing plate and stretches in the filtering area, be processed with water inlet and delivery port on the shell of filtering area, the installed inside of shell has screen pack, on the shell in blowdown district blowoff valve is installed.
With in the laterally inserted filtering area of spacer web, make the top of filtering area form the coarse filtration district then, the fine filtering district is formed at the bottom, and water inlet is positioned at the coarse filtration district, and delivery port is positioned at the fine filtering district.
Screen pack wherein is made up of coarse strainer and fie screen, and coarse strainer is installed in the shell inboard in coarse filtration district, and fie screen is installed in the shell inboard in fine filtering district, distinguishes for impurity and filters, and has effectively reduced the damage probability of filter screen.
Purging system is made up of blow-off pipe, hydraulic motors, hydraulic piston, and the delivery port of blow-off pipe is fixedlyed connected with the hydraulic motors water inlet, fixedlys connected with the expansion link of hydraulic piston in the bottom of hydraulic motors, and system installs rationally, and cleaning performance is better.
Suction nozzle is installed on blow-off pipe in addition.
Hydraulic motors across, water inlet are positioned at the upper end of hydraulic motors, and the left and right two ends of hydraulic motors have discharge outlet, and the direction of discharge outlet is opposite, and motor is lodged the waterpower running, reduces energy resource consumption, saves cost.
The bottom of hydraulic piston is equipped with the automatic pressure control switch.
The automatic anti-filter rinsed of paper pulp wastewater filter net type of utilizing the technical solution of the utility model to make, the whole system reasonable in design, good filtration effect, efficient height adopt waterpower as power, save cost, energy savings.
Description of drawings
Fig. 1 is the structural representation of the automatic anti-filter rinsed of paper pulp wastewater filter net type described in the utility model;
Among the figure, 1, housing; 2, coarse strainer; 3, fie screen; 4, dividing plate; 5, water inlet; 6, delivery port; 7, blowoff valve; 8, spacer web; 9, blow-off pipe: 10, hydraulic motors; 11, hydraulic motors water inlet; 12, expansion link; 13, hydraulic piston; 14, suction nozzle; 15, discharge outlet; 16, automatic pressure control switch.
The specific embodiment
Specifically describe of the present utility model below in conjunction with accompanying drawing, as Fig. 1 is the structural representation of the automatic anti-filter rinsed of paper pulp wastewater filter net type described in the utility model, as shown in the figure, in the insertion housing 1 that dividing plate 4 is horizontal, make the top of housing form filtering area, lower part of frame forms the blowdown district.Laterally inserted spacer web 8 in filtering area, make the top of filtering area form the coarse filtration district, the fine filtering district is formed at the bottom, and the installed inside that has water inlet 5 shells on the shell in coarse filtration district has coarse strainer 2, has to survey in delivery port 6 shells on the shell in fine filtering district fie screen 3 is installed.The delivery port of blow-off pipe 9 is fixedlyed connected with the hydraulic motors water inlet 11 of hydraulic motors 10, fixedly connected with the expansion link 12 of hydraulic piston 13 in the bottom of hydraulic motors, blow-off pipe, hydraulic motors and hydraulic piston are formed purging system, and whole system is installed in the bottom in blowdown district.Blowoff valve 7 is installed on the housing in blowdown district, suction nozzle 14 is installed on the blow-off pipe, automatic pressure control switch 16 is installed in the bottom of hydraulic piston,, his two ends, the left and right sides of hydraulic motors across have discharge outlet 15, and the direction of discharge outlet is opposite.
During the device operation, paper pulp wastewater water enters filtering area by water inlet, and by the bigger particle of elimination, the sewage that enters rough and careless district flows into the fine filtering district downwards by spacer web by coarse strainer the time, is flowed out by delivery port by after the filtration of fie screen again.When waste water is flowed through fie screen, suspension in the waste water can be filtered out and stick on the fie screen, fie screen is formed pressure differential, when pressure differential reaches setting numerical value, sewage draining valve will be opened the pressure that makes in the blowdown district automatically and descend, thereby is producing one suction on the suction nozzle with the suction of the bur on fie screen blow-off pipe.Current enter hydraulic motors via blow-off pipe, because the discharge outlet direction of hydraulic motors is opposite, so cause the hydraulic motors rotation when current can produce the reciprocal turning pair in diagonal angle to hydraulic motors when discharge outlet flows out, thereby drive blow-off pipe and suction nozzle rotation reach the cleaning purpose of fie screen on every side.After cleaning beginning a period of time, automatic empty controlled pressure valve opening is regulated suction nozzle in position longitudinally by the lengthwise movement of piston and expansion link, clears up whole fie screen completely.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art to some part wherein some changes that may make all embodied principle of the present utility model, belong within the protection domain of the present utility model.
