Abstract
The invention provides a telescopic elastic suction nozzle, relating to a suction nozzle which is used for a spiral suction typed filter and solves the problems that the suction nozzle of existing spiral suction typed filter is fixedly arranged; a clearance is remained between the suction nozzle and a filter screen, thus sundries with large viscosity can not be sucked and the cleaning effect is bad. The telescopic elastic suction nozzle is arranged at one side of a guide sleeve; the other side of the guide sleeve is connected with a position limit disc; the guide sleeve is provided with a spring which is arranged between the position limit disc and the suction nozzle. When impurities with large viscosity which are bonded to the filter screen are disposed by the suction nozzle of the invention, the suction nozzle closely attaches to the filter screen to suck the impurities; under the elastic force, the suction nozzle has a compensation function on the clearance change generated by the factors such as un-roundness, deformation, etc.; the elastic suction nozzle can ensure that the suction nozzle always contacts the internal surface of the filter screen, therefore, the impurities can be effectively removed and the filter screen is not damaged; the suction force of the telescopic elastic suction nozzle of the invention can sufficiently utilizes the water pressure after filtration, thus ensuring that the maximum of utilization of filtrated water pressure in the back-washing and sewage removing process by filter units.
Description
Technical field:
The present invention relates to a kind of suction nozzle that is used for spiral suctorial type filter.
Background technology:
At present, the suction nozzle that is positioned at the inboard blow-off pipe front end of filter screen of spiral suctorial type filter is hard-wired, foreign material on the strainer screen are cleared up by suction nozzle, leave the gap between suction nozzle and the filter screen, for the tough impurity on the filter screen, the suction of suction nozzle can't sop up foreign material, and cleaning effect is poor; The pressure of water is greater than the pressure of filter back water before the filter of filter screen both sides, and suction nozzle sucks water before the filter easily, causes filter chamber to wait to filter deformed damaged that former water waste and filter screen produce greatly owing to pressure reduction etc.; If suction nozzle is close to filter screen, the easy again distortion owing to filter screen makes suction nozzle damage filter screen.
Summary of the invention:
In order to solve the problem of above-mentioned existence, the invention provides and a kind ofly can directly contact screen surface and not destroy filter screen, the telescopic elastic suction nozzle that cleaning effect is good; The objective of the invention is to be achieved through the following technical solutions: telescopic elastic suction nozzle, comprise suction nozzle, suction nozzle is installed in a side of fairlead, and the opposite side of fairlead is connected with position-arresting disk, mounting spring on fairlead, spring is between position-arresting disk and suction nozzle.
Described position-arresting disk is connected with screw with fairlead.
Beneficial effect of the present invention: the present invention adopts said structure, because suction nozzle is installed on the fairlead, mounting spring on fairlead is screwed between fairlead and the position-arresting disk, and screw plays the fixedly effect of blow-off pipe and suction nozzle.During use, telescopic elastic suction nozzle can regulate as required and filter screen between distance, during viscosity is bigger on handling filter screen impurity, suction nozzle is close to filter screen and is sopped up, under the spring force effect, the gap that suction nozzle produces reasons such as the out-of-roundness of filter screen and distortion changes a compensating action, and this elastic suction nozzle can guarantee that suction nozzle contacts with the filter screen inner surface all the time when the problems referred to above occur, effectively removal of contamination guarantees that again filter screen is not destroyed; The suction of telescopic elastic suction nozzle of the present invention can make full use of filter back hydraulic pressure, good to the dirt cleaning effect that adheres on the filter screen inner surface, can sop up by the impurity that viscosity on the filter screen is bigger, make the basic free of losses of hydraulic pressure before the filter of filter screen both sides, filter back water pressure all act on washing away of impurity on the filter screen, guaranteed that filter element realizes the maximization of filter back hydraulic pressure utilization in backwash blowdown process.
Description of drawings:
Fig. 1 is the structural representation of telescopic elastic suction nozzle.
The specific embodiment:
Telescopic elastic suction nozzle, suction nozzle 5 is installed in a side of fairlead 4, spacing inboard boss by fairlead 4 towards filter screen one side is finished, the opposite side of fairlead 4 is connected with position-arresting disk 1 usefulness fluting awl end holding screw or shoulder screw 2, mounting spring 3 on fairlead 4, spring 4 during use is installed suction nozzle the inboard of blow-off pipe front end, filter screen between position-arresting disk 1 and suction nozzle 5.
Claims (2)
1, telescopic elastic suction nozzle comprises suction nozzle, it is characterized in that: suction nozzle is installed in a side of fairlead, and the opposite side of fairlead is connected with position-arresting disk, mounting spring on fairlead, and spring is between position-arresting disk and suction nozzle.
2, telescopic elastic suction nozzle according to claim 1 is characterized in that: described position-arresting disk is connected with screw with fairlead.
