Abstract
The utility model 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 a maximum degree.
Description
Technical field
The utility model relates to water treatment facilities, relates in particular to the front 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 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 control with electric control gear, need electric energy to come the cleaning and filtering of bootup window, and power consumption is large, cost is high, it is low to move continuously cost performance.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of filter that uses during (under the negative pressure state) continuous filtration before pump, it can filter protection to water pump and water system.Simultaneously, the cleaning dirty mechanism-nozzle by hydraulic motors during its backwash sprays and rotates the impurity of removing on the filter screen automatically, utilizes to greatest extent and purify the former water of rivers or underground water.
A kind of negative pressure self-cleaning of the utility model water filter, it is characterized in that: it comprises filter screen, housing; Top housing links to each other by 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 by filter screen, and bulky grain suspension and solid dirt are accumulated on the filter screen, prevent that them from entering water pump and water system, make clean water enter water pump and water system, thereby can filter protection to water pump and water system.
As this novel a kind of improved procedure, this filter 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 symmetrically the both sides of water main, and link to each other by threeway with water main, every distributive pipe is connected with respectively jet pipe, is provided with several nozzles on the jet pipe; 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 to greatest extent and purify the former water of rivers or underground water.
Description of drawings
Fig. 1 is the structural representation of this filter.
Fig. 2 is the structural representation of hydraulic water power motor.
The specific embodiment
As can be seen from Figure 1, this novel a kind of negative pressure self-cleaning water filter, it comprises filter screen 3, housing 4; Above housing 4 and following filter screen 3 link to each other by bolt.When this equipment of use; 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 by filter screen 3, and bulky grain suspension and solid dirt are accumulated on the filter screen 3, prevent that them from entering water pump and water system; make clean water enter water pump and water system, thereby can filter protection to water pump and water system.
As this novel a kind of improved procedure, this filter 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 symmetrically the both sides of water main 2, and link to each other by threeway with water main 2, every distributive pipe 6 is connected with respectively jet pipe 7, is provided with several nozzles 1 on the jet pipe 7; 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 single filter 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 whole filter screen inner surface.Be that distributive pipe 6, the jet pipe 7 that cleaning hose 5 orders about in the hydraulic motors by the hydraulic pressure water flow pressure rotates (rotary speed is adjustable) around water main 2, water is from some nozzles 1 ejections.The hydraulic water power motor constantly rotates, and 1 pair of from inside to outside cover type decontamination of whole filter screen 3 of nozzle is cleaned.This device cleaning dirty mechanism-nozzle by the hydraulic water power motor when backwash sprays and rotates the impurity of removing on the filter screen automatically, utilizes to greatest extent and purify the former water of rivers or underground water.
In order to guarantee that hydraulic water power motor when rotation is even, as this novel a kind of improved procedure, about nozzle 1 on two jet pipes 7 be arranged symmetrically with, and nozzle 1 is evenly arranged on jet pipe 7 from top to bottom.
In a word, the utility model is the natural physical characteristics such as pressure of utilizing water, by the back and forth Automatic continuous rotation in filter screen inside of Waterpower hydraulic pressure motor, utilize from the water of some nozzles 1 ejections and cover whole filter screen 3, to filter screen 3 clean, decontamination.
The utility model has been 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 Non-energy-consumption.The utility model can be used for the water processing establishment that sewage, reservoir, river, lake etc. realize that high-quality water inlet is filtered.
