Abstract
The invention discloses a scraping type self-cleaning filter, comprising a shell, a sewage inlet, a clear water outlet, a filter cylinder, an air cylinder, a gas supply system, a cleaning disc, a slag chamber, a cleaning valve, a pressure differential transducer and an electric controller, wherein the air cylinder is installed on the top of the shell; the cleaning disc is installed in the filter cylinder and tightly contacted with the inner wall of the filter cylinder; the middle part of the cleaning disc is connected with a piston rod of the air cylinder; the cleaning disc is provided with water-passing pores which are communicated up and down; the slag chamber is disposed below the filter cylinder; the cleaning valve is disposed between the slag chamber and the filter cylinder; the pressure differential transducer is disposed on the inner and outer sides of the filter cylinder; the pressure differential transducer, a control signal input terminal of the air cylinder and the cleaning valve are corresponding connected with signal terminals of the electric controller respectively; and the gas input end of the air cylinder is connected with the gas output end of the gas supply system. When the filter cylinder is obstructed, the pressure differential transducer can detect the pressure differential signals on the inner and outer sides of the filter cylinder; and the electric controller controls the air cylinder and the cleaning valve to operate, so as to achieve the self-cleaning object.
Description
Technical field
The present invention relates to a kind of filter, relate in particular to a kind of can automatically clean filter cylinder scrape the disc type self-cleaning filter.
Background technology
Filter is for the equipment to sewage or waste gas filtering impurity, existing effluent filter, mainly be comprised of the filter cylinder in housing and housing, and sewage enters from the sewage inlet of housing below, the filter cylinder of flowing through flows out by the clear water output in the middle part of housing, reaches the purpose of filtration.
Filter is after operation a period of time, and the filter cylinder inwall can precipitate a large amount of impurity, and filter cylinder is formed and stops up, and causes the filter effect variation.Existing effluent filter does not arrange automatic flushing device, need to take off manual cleaning to filter cylinder, reinstalls after cleaning is completed again, and, so the cleaning of filter cylinder is more loaded down with trivial details, both loses time, and efficiency is low again.
Summary of the invention
Purpose of the present invention with regard to be to provide in order to address the above problem a kind of can automatically clean filter cylinder scrape the disc type self-cleaning filter.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The present invention includes housing, sewage import, clear water output and filter cylinder, described sewage import and clear water output are installed on described housing, and described filter cylinder is arranged in described housing; The present invention also comprises cylinder, air supply system, cleaning disk, slag trapping chamber, wash-out valve, differential pressure pickup and electric controller, described cylinder is arranged on the top of described housing, described cleaning disk be arranged in described filter cylinder and with the inwall close contact of described filter cylinder, the middle part of described cleaning disk is connected with the piston rod of described cylinder, be provided with the water hole that communicates up and down on described cleaning disk, described slag trapping chamber is positioned at the below of described filter cylinder, and described wash-out valve is arranged between described slag trapping chamber and described filter cylinder; Described differential pressure pickup is installed on the interior outside of described filter cylinder, the signal output part of described differential pressure pickup is connected with the pressure difference signal input of described electric controller, the cylinder control signal output of described electric controller is connected with the control signal input of described cylinder, the valve control signal output of described electric controller is connected with the control signal input of described wash-out valve, and the gas input of described cylinder is connected with the gas output end of described air supply system.
In use procedure, the impurity in water constantly is deposited on filter cylinder, makes the outside in filter cylinder produce pressure reduction.Monitor the poor variation of side pressure inside and outside filter cylinder by differential pressure pickup, when pressure reduction reaches setting value, electric controller transmits operating instruction to cylinder and wash-out valve, causes following action: cylinder drives the cleaning disk by piston rod and moves down, and the filter cylinder inboard is cleaned, wash-out valve is opened filter residue is entered slag trapping chamber simultaneously, whole cleaning process only need continue tens of seconds, when cleaning end, and shifter cylinder and wash-out valve, system returns to its original state, starts to enter next filter progress.
Beneficial effect of the present invention is:
The present invention detects the pressure differential signal in the outside in filter cylinder by differential pressure pickup, thereby judges whether filter cylinder stops up, and when filter cylinder stopped up, electric controller control cylinder and wash-out valve action, reached automatic cleaning purpose.
