Abstract
A filter-core show system for exact filter comprises single chip, display, modulus transform circuit. There is a middle pressure sensor between two filtration tubes. The pressure sensor, signal large circuit, modulus transform circuit, single chip and display are conjoint each other. The pressure sensor detects the pressure from inlet-water tube to outlet-water tube at real time and transfers the signal to single chip. The single chip calculates the difference pressure. The filter-core pressure must be changed when the difference arrives a fixed value as the solid suspending arrives filter-core. The single chip exports signal to display and the display outputs hinted signal. The invention provides intuitionist and exact data and uses conveniently.
Description
Technical field:
The present invention relates to water treatment facilities, relate in particular to water filter, particularly a kind of filter core status display system that is used for accurate filter.
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 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 of filter core status display system that is used for accurate filter, the described this filter core status display system of accurate filter that is used for is by single-chip microcomputer, display, constitute with analog to digital conversion circuit, described accurate filter is made of two screen pipes at least, described screen pipe is communicated with in proper order, wherein, first screen pipe is provided with a water inlet pipe, last screen pipe is provided with an outlet pipe, be provided with one first pressure sensor in the described water inlet pipe, be provided with one second pressure sensor in the described outlet pipe, be provided with an intermediate pressure sensor between two adjacent arbitrarily screen pipes, described first pressure sensor, described second pressure sensor links to each other with a signal amplification circuit by lead respectively with described intermediate pressure sensor, described signal amplification circuit links to each other with described analog to digital conversion circuit, described analog to digital conversion circuit links to each other with described single-chip microcomputer, and described display links to each other with described single-chip microcomputer.
Further, described screen pipe is arranged in the container, and described display is arranged on the outer wall of described container.
Further, the upper end of any one described screen pipe is provided with a capping.
Further, described single-chip microcomputer is provided with a RS232 interface.
The course of work of the present invention is: the hydraulic pressure between first pressure sensor, second pressure sensor and intermediate pressure sensor detect respectively in real time from the water inlet pipe to the outlet pipe in each section screen pipe, and pass the signal along to single-chip microcomputer, single-chip microcomputer calculates the differential water pressures of each section screen pipe, when certain section differential water pressures reaches setting value, the solid suspension stop amount in this section filter core of promptly showing has arrived the replacing opportunity of filter core, single-chip microcomputer is to display unit output services signal, and display unit is sent cue.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention utilizes single-chip microcomputer to calculate water inlet pipe and the interior differential water pressures of outlet pipe by pressure sensor is set respectively in each section screen pipe between from the water inlet pipe to the outlet pipe, when differential water pressures reaches setting value, promptly sends cue by display unit.The present invention uses very convenient for the replacing of judging filter core provides visual and accurate foundation opportunity.
