Description of drawings
Fig. 1 is the structural representation of the utility model full automatic brush type self-cleaning filter;
Fig. 2 is the cutaway view of part among Fig. 1.
The specific embodiment
Among Fig. 1 and 2, the housing 3 of full automatic brush type self-cleaning filter is provided with water inlet 1 and delivery port 2, columniform filter screen 7 is installed in the housing 3, the corresponding two ends of filter screen 7 are separately fixed on the housing 3, the water inlet 8 of filter screen 7 communicates with the water inlet 1 of housing, mandrel 4 is positioned at the dead in line of filter screen 7 and axis and filter screen 7, the two ends of mandrel 4 are installed in housing 3 corresponding both ends respectively, the wherein end that one end of mandrel 4 passes housing 3 links to each other with the motor reducer 5 of housing 3 outsides, and motor reducer 5 links to each other with the output of motor 6.Brush is rectangle and is arranged in the filter screen 7, brush comprises rectangular framework 9 and bristle 10, framework 9 is fixedly mounted on the mandrel 4, bristle 10 is installed on the framework 9 parallel with mandrel 4 axis, the outward flange of bristle 10 contacts with the inner surface of filter screen 7, is provided with sewage draining exit 11 at filter screen 7 away from a side of the delivery port 2 of housing 3, and an end of blow-off pipe 12 joins by housing 3 and sewage draining exit 11, the other end communicates with the external world, and blow-off pipe 12 is provided with blowoff valve 15.The two ends of pressure difference switch 13 are separately positioned on the water inlet 1 and delivery port 2 places of housing 3, and control system 14 links to each other with motor 6, pressure difference switch 13 and blowoff valve 15 respectively.
During work, pending water is entered in the filter screen 7 through water inlet 8 by the water inlet 1 of housing 3, and the foul in the water, impurity are intercepted by filter screen 7, are trapped in the filter screen 7, clear water after the filtration enters in the housing 3 by the hole on the filter screen 7, and discharges to the external world through the delivery port 2 of housing 3.After the foul in the filter screen 7, impurity build up to a certain degree, form the impurity screening layer,, therefore formed a pressure reduction in the inside and outside both sides of filter screen 7 because impurity layer is deposited on the inner surface of filter screen 7.The pressure at this place is monitored at the two ends that are arranged on the pressure difference switch 13 at the water inlet 1 of housing 3 and delivery port 2 places at any time, when the pressure reduction at two ends reaches the predetermined value that pressure difference switch 13 sets, pressure difference switch 13 is transferred to control system 14 with signal, control system 14 is sent drive motors 6 and is opened the signal of blowoff valve 15, water filtration this moment process is uninterrupted, the water purification supply continues to flow, motor 6 drives mandrel 4 by motor reducer 5 and rotates, mandrel 4 drives the brush rotation, 10 pairs of filter screens 7 of bristle clean, because blowoff valve 15 has been opened, foul on filter screen 7 inner surfaces, impurity is under the momentum effect of water, enter blow-off pipe 12 by the sewage draining exit on the filter screen 7 11, be discharged from the external world, whole cleaning process only needs tens of seconds.Because filter screen 7 is cleaned totally, pressure difference switch 13 detected pressure differences are less, pressure difference switch 13 sends to control system 14 with detection signal, control system 14 is sent the signal that stops motor 6 runnings and close blowoff valve 15, and motor 6 stops operating, and blowoff valve 15 cuts out, system returns to the state of filtration, foul on filter screen 7, when impurities accumulation is a certain amount of, clean once more, go round and begin again.
Wherein, housing 3 materials are high-strength ductile cast iron, adopt the vacuum pressing and casting integral one-step molding.Mandrel 4 can also adopt other conventional drive unit to drive its rotation.The pressure difference switch 13 optional WFS11100AA type products of using Hai'an nest On-line Control technology Co., Ltd.When implementing pressure reduction control, also can control the enforcement time, by filtration time being set and cleaning the filter screen time, realization is cleaned the timing of filter screen 7, when reaching predetermined scavenging period, and 6 work of control system 14 drive motors, motor 6 drives the brush rotation, filter screen 7 is cleaned, and simultaneously, blowoff valve 15 is opened and is carried out blowdown, when scavenging period finishes, control system 14 is closed blowoff valve 15, and motor 6 stops operating, and the filtration state recovers in system.Pressure difference switch 13 can also substitute with two pressure sensors, one end of pressure sensor links to each other with control system 14, the other end is placed on the water inlet 1 and delivery port 2 places of housing 3 respectively, at any time detect the hydraulic pressure at two places, when the pressure reduction of two pressure sensors reaches predetermined value, control system 14 starts the program of cleaning filter screen, and program is identical with use pressure difference switch 13.In addition, brush also can have several frameworks 9, and a side of each framework 9 all is fixed on the mandrel 4, and framework 9 corresponding opposite sides are provided with bristle 10, like this, when motor 6 drives the brush rotation, can clean filter screen 7 more fast up hill and dale.When filter of the present utility model is installed, can by adjusting concrete parameter, set the scavenging period and the number of times of filter screen 7 according to the actual conditions of recirculated water to be filtered.
In order to raise the efficiency, can be by increasing the filter area of filter screen 7, like this, pollutant holding capability also improves simultaneously.Directly clean filter screen 7 owing to rotating at a high speed by motor 4 drive bristles, so scavenging period is short, the blowdown water consumption is also few, the power supply energy consumption is low simultaneously, and feeds water uninterruptedly, and system has also realized intelligent control.
