Abstract
The utility model relates to a self-cleaning filter used for the rough filtration of the priming pump medium. The filtering gate plate of the existing filter is easy to be blocked by the impurity absorbed in the filtering gate plate, the larger flow resistance of the medium is caused, the filtering effect is bad, the service life of the filtering gate plate is short, and the filtering gate plate needs to be cleaned frequently and timely during the using. The utility model includes a shell with an entrance and an exit and a filter core located in the shell, which is characterized in that: the filter core is in a cylinder shape, the opening end thereof is downward and connected with a core print seat which is in a funnel shape, the lower port of the core print seat is connected with a valve; a liquid inlet tube axially extending to the middle of the filter core is connected with the entrance, a helical opening is provided on the liquid inlet tube. When the work starts, the flow in the filter core rotates circling the axis line of the filter core, by which the impurity in the flow closes up to the axis line of the filter core and deposits rapidly before the medium passes the filter core, and the probability of the impurity blocking the filter core is reduced; the flow can scour the impurity adhered to the inner wall of the filter core, by which the probability of the impurity blocking the filter core is reduced greatly.
Description
[technical field]
The utility model relates to a kind of Filter for pump, is particularly suitable for the high medium of impurity content is filtered, and avoids stopping transport owing to cleaning impurity makes line equipment, is used for the coarse filtration of the preceding medium of pump more.
[background technology]
Existing filter is the Filter for pump of CN2408946Y such as notification number, and the medium that in use contains impurity roughly passes through to filter screen along the normal direction of filtering working face, and impurity then is adsorbed on by isolation and filters on the screen.The filter of this structure, it filters the impurity that screen easily is adsorbed thereon and stops up, and causes the resistance of media flow bigger, poor filtration effect, it is short to filter the screen life-span, must be frequently in the use cleaning and filtering screen timely.
[utility model content]
The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the above-mentioned defective that exists in the existing product, and a kind of filter that can the self-cleaning filter core is provided.For this reason, the utility model is taked following technical scheme:
A kind of self-cleaning filter comprises the housing that has import and export and is positioned at filter core in the housing, it is characterized in that described filter core is cylindric, its openend downwards and be connected on the funnelform core print seat, the lower port of core print seat is connected with valve; Be connected with the feed tube that axially extends the filter core middle part in the described import, on this feed tube helical opening be set.In the filter course of work, liquid stream in the filter core will make that the impurity in the liquid stream is drawn close and rapid precipitation to the filter core axial line, before medium passes through filter core around the rotation of filter core axial line, existing most impurity precipitates voluntarily, has reduced the probability of the stifled match of impurity filter core; Simultaneously, the circular motion of liquid stream, to playing the effect of washing away attached to the impurity on the filter core inwall, the probability that makes impurity stop up filter core reduces greatly.
Described self-cleaning filter is characterized in that being connected with on the described housing device lid, is equipped with stage clip, the dismounting of filter core when being convenient to clean filter core between device lid and the filter core; Device covers and also is connected with air bleeding valve, is used for the discharge of filter internal upper part air.
Described self-cleaning filter is characterized in that the lower end of described housing is provided with sewage draining exit, the blowdown when being used for comprehensively cleaning.
Described self-cleaning filter is characterized in that the lower end of described valve is connected with sludge tank, is used to store residue.
The utility model is by with the openend of cylindric filter core downwards and be connected on the funnelform core print seat, the feed tube that helical opening is set is also axially extended the filter core middle part mutually with import, thereby in the filter course of work, liquid stream in the filter core will rotate around the filter core axial line, make the impurity in the liquid stream draw close and rapid precipitation to the filter core axial line, by before the filter core, existing most impurity precipitates voluntarily at medium, has reduced the probability of the stifled match of impurity filter core; Simultaneously, the circular motion of liquid stream, to playing the effect of washing away attached to the impurity on the filter core inwall, the probability that makes impurity stop up filter core reduces greatly, and the flow resistance of medium is little, and the life-span is long, can avoid its frequent cleaning when guaranteeing the normal filtration effect.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that A-A among Fig. 1 is to view.
[specific embodiment]
Self-cleaning filter as shown in Figure 1, by filter body, sludge tank 11, and valve 9 three parts that connect are between the two formed: wherein filter body comprises the cylindric filter core 6 that is welded on the funnel-form core print seat 7 in the housing 5 and is positioned at core print seat 7 upper ends by the seam that cooperatively interacts, the taper of filter core 6 is filtered working face and is convenient to coming off voluntarily of impurity on the filter screen, the device that is spirally connected on the flange of housing 5 upper ends lid 4, between device lid 4 and filter core 6, be equipped with stage clip 3, also be connected with air bleeding valve 18 on the device lid 4, outlet 8 and import 15 are positioned at housing 5 left and right sides, the feed tube 17 (seeing Fig. 2 for details) that tangential screw shape opening 19 is set is connected in the import 15 and the inclined-plane 16 that passes core print seat 7 axially extends filter core 6 middle parts, and the lower end of housing 5 also is provided with sewage draining exit 14; For the installing/dismounting aspect, be connected with handle 2 in the upper end of filter core, the upside connection hoisting ring 1 at the device lid is used for the lifting to filter, and housing 5 lower ends are provided with feet 10.The sludge tank 11 that is positioned at housing 5 downsides is connected core print seat 7 lower ends by valve 9, and its bottom is provided with wheel 13 and sewage draining exit 12.
During operate as normal, valve 9 should be opened, make residue along inclined-plane 16 landings of core print seat 7 to sludge tank, wait when residue is filled with in the sludge tank, valve-off 9 under the situation of the line equipment of not stopping transport, can clean sludge tank.
