Self-cleaning filter device before the above-mentioned pump, its brush device is made of hairbrush support and hairbrush, between hairbrush support and the outlet pipe support disk spacing is arranged.
Self-cleaning filter device before the above-mentioned pump, its anti-scavenge pipe extend internally near impeller, make impeller can be subject to maximum initial impact force.
Self-cleaning filter device before the above-mentioned pump, the relative sealing ring in its brush device lower end is provided with the ring-type partition, and partition lower end bossing stretches in the sealing ring, reduces friction, and is conducive to the motion of brush device.
Self-cleaning filter device before the above-mentioned pump, two sections of its gland and housing epimere, housings are bolt and are connected, in order to dismantle.
Advantage of the present invention is as follows:
The invention provides the front self-cleaning filter device of a kind of pump, be provided with brush device at the filter core outer wall, by the impurity of anti-cleaning process on can more efficiently removing screen pack, in the process of filtering and instead cleaning, only need close and open relevant controller, in anti-process of cleaning, by the water slug impeller in the anti-cleaning feed pipe, make it directly drive brush gear and rotate, owing to having increased brush gear, add the anti-cleaning of current so that anti-cleaning performance is obvious, fully, hydraulic pressure is lower before the pump, impurity can not cause large damage to filter screen, filters the damage by water that produces after filtration can reduce pump before the pump, has strengthened the pressure of back water economizer.
It has the advantages such as the developing result of enhancing, the loss of minimizing filter screen, raising water saving intensity.This invention is simple in structure, easy and simple to handle, effectively improve the service efficiency of filter, reduces operating cost.
Description of drawings
Accompanying drawing 1 is the cutaway view of embodiment part among the present invention.
Accompanying drawing 2 is the partial sectional view among embodiment Fig. 1 among the present invention.
Among Fig. 1-2,1 controller, 2 for outlet pipe, 3 be that the mouth of a river, 4 is gland for housings support disk, 16 for delivery port support disk, 15 for blow-off pipe, 14 for partition, 13 for water inlet pipe, 12 for filter core, 11 for hairbrush, 10 for housing, 9 for sealing ring, 8 for hairbrush support, 7 for impeller, the 5 anti-feed pipes, 6 that clean.
The specific embodiment
With reference to accompanying drawing 1,2, the present embodiment comprises gland 16, water inlet pipe 11, blow-off pipe, filter core 10, sealing ring 7, housing 8 forms by two sections, and for bolt connects detachable, housing 8 epimere inwalls are provided with the housings support disk 15 concordant with its lower end, outlet pipe 2 passes gland 16, and its outer wall is provided with the delivery port support disk 14 concordant with housings support disk 15, outlet pipe 2 outer walls are provided with impeller 4, housing 8 is provided with anti-cleaning feed pipe 5, outlet pipe 2 was provided with the mouth of a river 3 on the impeller 4, impeller 4 is provided with brush device, brush device is comprised of hairbrush support 6 and hairbrush 9, brush device is passed down through gap between housings support disk 15 and the delivery port support disk 14 to housing 8 bottoms, be movable sealing between brush device and housings support disk 15 and the delivery port support disk 14, the relative sealing ring in brush device lower end is provided with ring-type partition 12, and partition 12 lower end bossings stretch in the sealing ring.Filter core 10 is positioned at the brush device inwall, and sealing ring 7 is positioned at up and down two ends of filter core, and water inlet pipe 11, blow-off pipe 13 and the anti-feed pipe 5 that cleans are provided with controller 1.
Occupation mode of the present invention and principle are as follows:
Self-cleaning filter device can used aloned before the pump, also can use in groups.
The mode of used aloned, namely water inlet pipe and water supply installation connect together, and backwash tube and delivery port connect together, and outlet pipe and pump connect together, and blow-off pipe and blow-off line connect together.
The process of cleaning is: water enters water inlet pipe, hairbrush from water supply installation, by entering the filter chamber body after the filtering element (cartridge) filtration, the outlet pipe of flowing through enters the need aqua region to pump and delivery port, and this moment, the anti-controller that cleans on feed pipe and the blow-off pipe cut out the controller opens on water inlet pipe, the outlet pipe.
Anti-cleaning process is: close the controller on water inlet pipe, the outlet pipe, open the controller on anti-cleaning feed pipe and the blow-off pipe, when water is flowed through impeller from anti-cleaning feed pipe, part water enters filter cartridge flushing in the filter core chamber by circular port, part water slug impeller band electric brush support and hairbrush carry out anti-cleaning, thereby reach the effect of anti-cleaning, the sewage after anti-the cleaning is discharged by sewage draining exit.
The mode of using in groups, namely water inlet pipe connects together from the two ends of water supply installation respectively, and backwash tube connects together from the delivery port two ends respectively, and outlet pipe connects together from the pump two ends respectively, and blow-off pipe connects together from the blow-off line two ends respectively.
The process of cleaning is: water enters water inlet pipe, hairbrush from water supply installation, by entering the filter chamber body after the filtering element (cartridge) filtration, the outlet pipe of flowing through enters the need aqua region to pump and delivery port, and this moment, the anti-controller that cleans on feed pipe and the blow-off pipe cut out the controller opens on water inlet pipe, the outlet pipe; Anti-cleaning process is: a filter is normal filtration work, water inlet pipe on this filter, the controller opens on the outlet pipe, controller on anti-scavenge pipe, the blow-off pipe cuts out, another filter then is anti-cleaning, anti-cleaning process is consistent when its course of work such as used aloned, use in groups filtration and anti-cleaning are carried out simultaneously, improve the operating efficiency of filter.
The present invention is simple in structure, and housing divides two sections compositions, is convenient to dismounting and maintenance, and filter process and the control of anti-cleaning process are convenient, is widely used in the front filtration system of various pumps.
