Description
Technical Field
The utility model relates to a filter technical field especially relates to a self-cleaning filter.
Background
With the improvement of living standard, the requirement of people on drinking water safety is higher and higher, and therefore, the drinking water filter is widely used.
The core of the drinking water filter is a filter screen, and in order to reduce the use cost, the filter screen needs to be cleaned or replaced when impurities are excessive. The dismantlement of filter screen is changed more loaded down with trivial details, and material cost is high, consequently most carries out the diversion of rivers through the pipeline that the design corresponds, through rivers to filter screen backwash, among the prior art, the pipeline design of rivers diversion is more complicated, has increased the degree of difficulty and the cost of production.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a self-cleaning filter realizes the initiative cleanness of filter screen inner wall, reduces the production degree of difficulty and cost, reduces and maintains the frequency.
To achieve the purpose, the utility model adopts the following technical proposal:
a self-cleaning filter comprising: top cap, bottom, barrel and filter screen, the top cap sets up the top at the barrel, the bottom sets up the bottom at the barrel, the filter screen sets up in the barrel with one heart and is located between top cap and the bottom, be provided with downwardly extending's retaining ring in the top cap and divide into the annular that is located the retaining ring outside and be located the retaining ring inboard with the first jack that the filter screen top corresponds with the top cap inner chamber, the filter screen is the tubular structure, be provided with the several floater in the filter screen, be provided with the water supply connector with first jack intercommunication on the top cap, the bottom is provided with the blowdown coupling, be provided with the outlet pipe joint with the annular intercommunication on the top cap.
And threaded holes corresponding to the top cover and the bottom cover are respectively formed at two ends of the barrel.
Wherein, the floating ball is a hollow plastic ball.
The check ring, the water inlet pipe joint, the top cover and the water outlet pipe joint are of an integrated plastic structure or a metal structure.
Wherein, the bottom cover is provided with a second jack corresponding to the bottom of the filter screen in an inwards concave manner.
Wherein, the first jack and the second jack are stepped holes respectively.
The utility model has the advantages that: the utility model provides a self-cleaning filter, rolls up and down in the filter screen through the floater along with rivers, carries out the clearance of impurity when contacting with the filter screen inner wall, reduces the attached to of impurity at the filter screen inner wall for impurity sinks to the bottom in, regularly opens the external blowdown valve of blow off pipe connector, can realize the concentrated clearance of impurity, and is easy and simple to handle, and the structure is succinct, and the production degree of difficulty is little, and processing cost is low.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solution of the present invention is further explained by the specific embodiment with reference to fig. 1.
The self-cleaning filter shown in fig. 1 comprises: top cap 2, bottom 3, barrel 1 and filter screen 11, top cap 2 sets up the top at barrel 1, bottom 3 sets up the bottom at barrel 1, 1 both ends of barrel are provided with the screw hole that corresponds with top cap 2 and bottom 3 respectively, are provided with the external screw thread on top cap 2 and the bottom 3, connect through the screw thread mode, and easy dismounting, the leakproofness is good.
The water supply device is characterized in that a water inlet pipe connector 9 communicated with the first jack 8 and an external water supply pipeline are arranged on the top cover 2, and a water outlet pipe connector 10 communicated with the annular groove 6 and an external water outlet pipeline are arranged on the top cover 2. Water flow is guided into the filter screen 11 from the first insertion hole 8, the diameter of the inner hole of the cylinder body 1 is larger than the diameter of the outer circle of the filter screen 11, so that the filtered water flows into the annular groove 6 and is discharged through the water outlet pipe joint 10 during water use. The retainer ring 7, the water inlet pipe connector 9, the top cover 2 and the water outlet pipe connector 10 are of an integrated plastic structure or a metal structure, the integrated plastic structure is preferentially adopted, the corrosion is avoided, and the production cost is low.
As shown in fig. 1, the filter screen 11 is the tubular structure, be provided with several floater 4 in the filter screen 11, floater 4 is the hollow plastic ball, adopts food level plastics to make, and the dead weight is light, and buoyancy is big, rolls about in the filter screen 11 along with rivers through floater 4, increases floater 4 to the contact of filter screen 11 inner wall, carries out the initiative clearance of impurity for impurity sinks to in the bottom 3, and is effectual from cleaning, reduces the attached to and the jam of impurity at the filter screen 11 inner wall.
The bottom of the bottom cover 3 is provided with a sewage pipe joint 5, the external sewage valve is connected with the sewage valve, the sewage valve is opened periodically, the concentrated cleaning and discharging of impurities can be realized, the operation is simple and convenient, the structure is simple, the production difficulty is small, and the processing cost is low.
The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
