Description

Filter equipment for rural well

Technical Field

The utility model belongs to the technical field of well water filtering devices, and relates to a filtering device for rural wells.

Background

The well is a mode of taking well water that vast rural area adopted, contain a large amount of silt in the well water, river sand or other large granule impurity, can drink after needing to handle, because the condition restriction, people often adopt the method of natural sedimentation to make large granule impurity deposit in the bottom of cask, then ladle the water at top with the water ladle and drink, impurity and water are not separated to this kind of processing mode, the filter effect is not good and consuming time is long, very big inconvenience has been caused to daily life, and the pipeline among the prior art can adopt the sponge, the filter mode of gauze, the sponge of this filter mode absorbs impurity for a long time and causes secondary pollution easily and the change of sponge is very inconvenient.

Disclosure of Invention

The utility model aims to solve the problems in the prior art and provides a filter device for rural wells. The technical problem solved by the utility model is to better filter the well water.

The purpose of the utility model can be realized by the following technical scheme:

the utility model provides a filter equipment for rural well, includes the filter tube, its characterized in that, is provided with hollow filter core in the filter tube, and the top of filter tube is provided with the fixed cover of intaking that is used for connecting the inlet tube, is provided with the check valve body that is used for intercommunication inlet tube and filter core between the fixed cover of the top of filter core and intaking, and the bottom of filter tube is provided with the fixed cover of play water that is used for connecting the outlet pipe, and the bottom of filter core and play water are provided with the play water sleeve pipe that is used for intercommunication outlet pipe and filter core between the fixed cover, filter tube, filter core, the fixed cover of intaking, check valve body, play water sleeve pipe and play water and form confined filter chamber between the fixed cover, a plurality of inlet openings that are used for intercommunication inlet tube and filter chamber are seted up to the lateral wall of check valve body.

When the submersible pump works to pump well water, the well water containing impurities flows to the filtering device through the water inlet pipe, the ball body in the check valve body is driven by water flow to roll to the position of the closed water through hole, the check valve body is closed, the well water containing impurities can only flow to the filtering cavity from the water inlet hole on the side wall of the check valve body, the well water containing impurities is filtered by the filtering core in the filtering cavity, clean well water enters the filtering core and then flows out sequentially through the water outlet sleeve and the water outlet pipe, silt, river sand or other large-particle impurities in the well water are left in the filtering cavity, and the clean well water flows to the water outlet pipe after passing through the filtering core; when the immersible pump stopped to extract well water (when not using water), because well water is underground, produces water head pressure, the interior remaining clean well water of filter core can be washed away the spheroid under the effect of pressure (the check valve body is opened after washing away the spheroid) and flow back to the well through water hole, inlet tube, and silt, river sand or other large granule impurity in the well water still remain in the filter chamber, can not bring silt, river sand or other large granule impurity back to in the well during the return water yet to can filter well water better.

In the filter device for rural wells, the one-way valve body comprises a valve body, the bottom of the valve body is positioned in the filter element and is provided with a water passing hole, a ball body capable of plugging or opening the water passing hole is arranged in the valve body, and a limit pin capable of preventing the ball body from separating from an inner cavity of the valve body is arranged on the valve body.

Spacer pin easy dismounting, make spheroidal assembly more convenient, also make check valve body's inner chamber and spheroidal washing more convenient, when rivers flow into the valve body inner chamber from the upper end of valve body, the spheroid rolls the position of sealing the water hole under the drive of rivers, and with the water hole of crossing closely laminating, form good gas tightness, in order to pass through with the well water that contains impurity, when the immersible pump stops to extract well water, remaining clean well water in the filter core can be washed away the spheroid through the water hole under the effect of pressure, the inlet tube flows back to in the well, the spacer pin can prevent that rivers from washing away the valve body inner chamber with the spheroid.

In foretell filter equipment for rural well, the both ends of the fixed cover of intaking all are provided with the external screw thread, be provided with on the filter tube and be used for with the solid fixed ring one of the one end threaded connection of the fixed cover of intaking, be provided with on the inlet tube and be used for with the solid fixed ring two of the other end threaded connection of the fixed cover of intaking.

In the filter device for the rural well, the two ends of the water outlet fixing sleeve are provided with external threads, the filter pipe is provided with a third fixing ring in threaded connection with one end of the water outlet fixing sleeve, and the water outlet pipe is provided with a fourth fixing ring in threaded connection with the other end of the water outlet fixing sleeve.

The structure of threaded connection makes filter equipment make things convenient for the dismouting, is convenient for handle the impurity of filter chamber in, also conveniently washs each part of filter equipment.

In the filter device for the rural well, the water inlet fixing sleeve is provided with a first inner step surface, the top of the one-way valve body is provided with a first flanging, and the first flanging is abutted to the first inner step surface.

In the filter device for the rural well, the water outlet fixing sleeve is provided with the inner step surface II, the water outlet sleeve is provided with the flanging II, and the flanging II is abutted to the inner step surface II.

The abutting structure of the inner step surface and the outer flanging ensures that the filter cavity is better in sealing performance.

Compared with the prior art, this filter equipment for rural well's advantage lies in: when the filter device for the rural well is used for pumping well water, the well water containing impurities flows to the filter device through the water inlet pipe, the ball body in the check valve body is driven by water flow to roll to the position of the closed water passing hole, the check valve body is closed, the well water containing impurities can only flow to the filter cavity from the water inlet hole on the side wall of the check valve body, the well water containing impurities is filtered by the filter core in the filter cavity, clean well water enters the filter core and then flows out through the water outlet sleeve and the water outlet pipe in sequence, silt, river sand or other large-particle impurities in the well water are left in the filter cavity, and the clean well water flows to the water outlet pipe after passing through the filter core; when the submersible pump stops pumping well water (when water is not used), because the well water is underground, water level drop pressure is generated, clean well water remained in the filter core can be flushed away from the ball body under the action of the pressure, and flows back into the well through the water hole and the water inlet pipe, so that the well water can be better filtered.
