Abstract
A method to judge the time of changing filter-core of precision filter is disclosed. It comprises: The step of measuring pressure at the water-import of exact filter for the first time and at least the step of measuring pressure at the water-import of exact filter for the second time; The step of comparing water pressure measured first time and second time. The device that achieves said method comprises at least two tub form components. The connective part of with the first tub form components connects import-water tube; said import-water has a pressure watch. The invention detects the change of pressure in filter by pressure watch. The filter-core pressure must be changed when the difference arrives a fixed value.
Description
Technical field:
The present invention relates to water treatment facilities, relate in particular to water filter, particularly a kind ofly judge that filter core in the accurate filter changes the method and apparatus on opportunity.
Background technology:
In the prior art, organic matter, chloride are fallen in the solid suspension and the absorption that generally utilize filter to cooperate filter core to remove in the water.In the filter in the prior art, water by water inlet enter, with certain flow velocity successively by a plurality of filter cores, the water that obtains handling well from delivery port at last, solid suspension is then stayed in the filter core, filter core needs to change after using a period of time.Be the service time according to filter core the opportunity of judging the filter core replacing in the prior art, still, if the flow velocity of water is bigger in the processing procedure, then is difficult to judge the replacing opportunity of filter core, causes filter core to use later stage water quality uncontrollable.
Summary of the invention:
Technical problem of the prior art to be solved by this invention is: because in the filter in the prior art, water is entered, is passed through a plurality of filter cores successively with certain flow velocity by water inlet, the water that obtains handling well from delivery port at last, solid suspension is then stayed in the filter core, and filter core needs to change after using a period of time.Be the service time according to filter core the opportunity of judging the filter core replacing in the prior art, still, if the flow of water is bigger in the processing procedure, then is difficult to judge the replacing opportunity of filter core, causes filter core to use later stage water quality uncontrollable.
The technical scheme that the present invention is adopted for solution above-mentioned technical problem of the prior art provides a kind ofly judges that filter core in the accurate filter changes the method on opportunity, the method that filter core is changed opportunity in the described this judgement accurate filter comprises measures the step of hydraulic pressure and at least one measures the step of hydraulic pressure for the second time at the water inlet of accurate filter at the water inlet of accurate filter a first time, also comprise one with hydraulic pressure value that measures for the first time and the hydraulic pressure value that measures for the second time step relatively, the step that measure hydraulic pressure at the water inlet of accurate filter the described first time is that the step of carrying out measuring hydraulic pressure at the water inlet of accurate filter the described second time when filter core initially uses is to carry out at random after measuring for the first time.
Further, the step of measuring hydraulic pressure at the water inlet of accurate filter the described second time is to carry out continuously after measuring for the first time.
The present invention also provides a kind of and has realized that filter core in the described judgement accurate filter changes the device of the method on opportunity, described this device is made of at least two tubular elements, wherein, the upper side of any one described tubular element and lower end are provided with a connector respectively, described tubular element is communicated with by its connector order successively, the upper surface that is provided with any one described tubular element of filter core in any one described tubular element is provided with capping, wherein first tubular element connector is connected with a water inlet pipe, is provided with a Pressure gauge in described water inlet pipe.
Further, described tubular element all is arranged in the container, and described water inlet pipe passes the sidewall of described container, and described Pressure gauge is fixed on the outer wall of described container.
Further, the upper end of described container is provided with a container cover.
Following principle of the present invention is: when filter core used, wherein solid suspension constantly increased, and when the pressure differential of twice measurement reaches setting value, showed that the solid suspension stop has hindered current in the filter core, i.e. the replacing opportunity of filter core has been arrived in prompting.The present invention uses very convenient for the replacing of judging filter core provides visual and accurate foundation opportunity.Contrast with prior art, its effect is actively with tangible.The present invention comes variation in water pressure in the detection of dynamic filter by Pressure gauge is set at water inlet, when Pressure gauge shows that hydraulic pressure increases, show that solid suspension stops increase in the filter core, when Pressure gauge shows hydraulic pressure to setting value, i.e. the replacing opportunity of filter core has been arrived in prompting.The present invention uses very convenient for the replacing of judging filter core provides visual and accurate foundation opportunity.
Description of drawings:
Fig. 1 of the present inventionly a kind ofly judges that filter core in the accurate filter changes the structural representation of the device on opportunity.
