Abstract
The invention discloses a negative pressure self-cleaning water filter, comprising a filter screen and a filter housing; and the above housing and the lower filter screen are connected by a bolt. For usage of the equipment, the filter screen is immersed and installed in a water source to connect an outlet of the housing with a pump. When the water pump begins, water flow passes through the filter screen, and large particle suspended solids and solid dirt accumulate on the filter screen, so that clean water enters into the water pump and a water supply system. The invention also comprises a flushing pipe, and a hydraulic power motor placed in the filter screen. The hydraulic power motor comprises a main water pipe, distributive water pipes and spray tubes; the left distributive water pipe and the right distributive water pipe are connected with the main water pipe through tee joints; each distributive water pipe is respectively connected with a spray tube, which is provided with a plurality of nozzles; and the flushing pipe is fixed on a side surface of the housing, and connected with the main water pipe of the hydraulic power motor. For backwashing, the flushing pipe is connected with the pump, and water ejects from the nozzle to clean and decontaminate the filter screen, so as to utilize and purify river water or groundwater to the maximum degree.
Description
Technical field
The present invention relates to water treatment facilities, relate in particular to the preceding negative pressure self-cleaning strainer of a kind of pump.
Background technology
At present China's water filtering device mainly uses behind pump, comprises that self-cleaning is brush, suction formula and multi-cartridge filter, and its shortcoming is can not carry out (under the negative pressure state) to water pump and water system to filter protection.Simultaneously, these filters all are to use electric control gear to control, and need electric energy to come the cleaning and filtering of bootup window, and power consumption is big, high, the continuous maneuverability price ratio of cost is low.
Summary of the invention
The technical problem that the present invention will solve provides a kind of filter that before pump, uses during (under the negative pressure state) continuous filtration, and it can filter protection to water pump and water system.Simultaneously, the mechanism-nozzle of removing contamination through hydraulic motors during its backwash sprays and rotates the impurity of removing on the filter screen automatically, utilizes and purify former water of rivers or underground water to greatest extent.
A kind of negative pressure self-cleaning of the present invention water filter, it is characterized in that: it comprises filter screen, housing; Top housing links to each other through bolt with following filter screen.
When using this equipment, the submergence of filter screen body is installed in the water source, the outlet of housing is linked to each other with pump.When drawing water beginning, current are through filter screen, and bulky grain suspension and solid dirt are accumulated on the filter screen, prevent that them from getting into water pump and water system, make clean water get into water pump and water system, thereby can filter protection to water pump and water system.
As a kind of improved procedure of the present invention; Filter of the present invention also comprises cleaning hose, is placed on the hydraulic water power motor in the filter screen; The hydraulic water power motor comprises water main, distributive pipe, jet pipe, about two distributive pipes be in the both sides of water main symmetrically, and link to each other through threeway with water main; Every distributive pipe is connected with jet pipe respectively, and jet pipe is provided with several nozzles; Cleaning hose is fixed on the side of housing, and links to each other with the water main of hydraulic water power motor.During backwash, cleaning hose is linked to each other with pump like this, water sprays from nozzle, to filter screen clean, decontamination, utilize and purify former water of rivers or underground water to greatest extent.
Description of drawings
Fig. 1 is a structure of filter sketch map of the present invention.
Fig. 2 is the structural representation of hydraulic water power motor.
The specific embodiment
Can know from Fig. 1, a kind of negative pressure self-cleaning of the present invention water filter, it comprises filter screen 3, housing 4; Above housing 4 and following filter screen 3 link to each other through bolt.When using this equipment, filter screen 3 body submergences are installed in the water source, the outlet of housing 4 is linked to each other with pump; When drawing water beginning; Current are through filter screen 3, and bulky grain suspension and solid dirt are accumulated on the filter screen 3, prevent that them from getting into water pump and water system; Make clean water get into water pump and water system, thereby can filter protection water pump and water system.
As a kind of improved procedure of the present invention; Filter of the present invention also comprises cleaning hose 5, is placed on the hydraulic water power motor in the filter screen 3; The hydraulic water power motor comprises water main 2, distributive pipe 6, jet pipe 7, nozzle 1, about two distributive pipes 6 be in the both sides of water main 2 symmetrically, and link to each other through threeway with water main 2; Every distributive pipe 6 is connected with jet pipe 7 respectively, and jet pipe 7 is provided with several nozzles 1; Cleaning hose 5 is fixed on the side of housing 4, and links to each other with the water main 2 of hydraulic water power motor.During backwash, cleaning hose 5 is linked to each other with pump like this, water is from nozzle 1 ejection, to filter screen 3 clean, decontamination.
Wherein, the precision of filter screen 3 is 0.4mm, and therefore being filtered into the one-level filtration is coarse filtration.
In order further to guarantee the effect of backwash, the hydraulic water power motor also comprises connection bearing, and connection bearing is arranged on the position of threeway.Like this, the hydraulic water power motor is directed 360 degree rotations under the bearing effect, clean and cover the whole filtering net inner surface.Be that distributive pipe 6, the jet pipe 7 that cleaning hose 5 orders about in the hydraulic motors through the hydraulic pressure water flow pressure rotates (rotary speed is adjustable) around water main 2, water is from plurality of nozzles 1 ejection.The hydraulic water power motor constantly rotates, and 1 pair of whole filtering net 3 cover type decontamination from inside to outside of nozzle is cleaned.This device mechanism-nozzle of removing contamination through the hydraulic water power motor when backwash sprays and rotates the impurity of removing on the filter screen automatically, utilizes and purify former water of rivers or underground water to greatest extent.
In order to guarantee that hydraulic water power motor when rotation is even, as a kind of improved procedure of the present invention, about nozzle 1 symmetric arrangement on two jet pipes 7, and nozzle 1 is evenly arranged on jet pipe 7 from top to bottom.
In a word, the present invention is natural physical characteristics such as pressure of utilizing water, through the automatically continuously rotation back and forth of waterpower hydraulic motor, utilize from the water of plurality of nozzles 1 ejection and cover whole filtering net 3 in filter screen inside, to filter screen 3 clean, decontamination.
The present invention has abandoned electronic control, has reduced energy consumption, has simplified filter type; Adapt to various adverse circumstances, it is simple in structure, easy to maintenance, the life-span is long, has reached the effect of Separation of Solid and Liquid; Having reduced production cost, is negative pressure self-cleaning water filter before a kind of pump of desirable no energy consumption.The present invention can be used for the water processing establishment that sewage, reservoir, river, lake etc. realize that high-quality water inlet is filtered.
