Abstract
The utility model relates to a scraping disc type self-cleaning filter which comprises a shell, a sewage inlet, a clear water outlet and a filter cartridge; the sewage inlet and the clear water outlet are arranged on the shell; the filter cartridge is arranged in the shell; the filter is characterized by further comprising a cylinder, an air supply system, a cleaning disc, a residue collecting chamber, a cleaning valve, a differential pressure transducer and an electric controller; the cylinder is arranged on the top of the shell; the cleaning disc is arranged in the filter cartridge and is closely contacted with the inner wall of the filter cartridge; the middle part of the cleaning disc is connected with a piston rod of the cylinder; the cleaning disc is provided with water through holes communicated with each other up and down; the residue collecting chamber is arranged under the filter cartridge; the cleaning valve is positioned between the residue collecting chamber and the filter cartridge; the differential pressure transducer is arranged at inner and outer sides of the filter cartridge; a signal output end of the differential pressure transducer is connected with a pressure difference signal input end of the electric controller; a cylinder control signal output end of the electric controller is connected with a control signal input end of the cylinder; a valve control signal output end of the electric controller is connected with a control signal input end of the cleaning valve; and a gas input end of the cylinder is connected with an air output end of the air supply system. The filter is capable of detecting pressure difference signals at inner and outer sides of the filter cartridge by the differential pressure transducer, thus judging whether the filter cartridge is plugged; and when the filter cartridge is plugged, the cylinder and the cleaning valve are controlled to act by the electric controller, so that the aim of automatic cleaning can be achieved.
Description
Technical field
The utility model 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 is comprised of the filter cylinder in housing and the 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 the 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, filter cylinder is formed stop 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 finished again, so the cleaning of filter cylinder is more loaded down with trivial details, both loses time, and efficient is low again.
Summary of the invention
The purpose of this utility model 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 utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises housing, sewage import, clear water output and filter cylinder, and described sewage import and clear water output are installed on the described housing, and described filter cylinder is installed in the described housing; The utility model also comprises cylinder, air supply system, cleaning disk, slag trapping chamber, wash-out valve, differential pressure pickup and electric controller, described cylinder is installed in the top of described housing, described cleaning disk be installed in the 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 the 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 the 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 the use procedure, the impurity in the water constantly is deposited on the filter cylinder, makes generation pressure reduction in the outside in the filter cylinder.By the poor variation of side pressure inside and outside the differential pressure pickup monitoring filter cylinder, 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, begins to enter next filter progress.
The beneficial effects of the utility model are:
The utility model detects the pressure differential signal in the outside in the 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.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in drawings, the utility model comprises housing 4, sewage import 8, clear water output 9, filter cylinder 5, cylinder 1, the air supply system (not shown), clean disk 3, slag trapping chamber 7, wash-out valve 6, differential pressure pickup (not shown) and electric controller (not shown), sewage import 8 and clear water output 9 are installed on the housing 4, filter cylinder 5 is installed in the housing 4, cylinder 1 is installed in the top of housing 4, clean that disk 3 is installed in the filter cylinder 5 and with the inwall close contact of filter cylinder 5, the middle part of cleaning disk 3 is connected with the piston rod 2 of cylinder 1, clean on the disk 3 and be provided with the water hole that communicates up and down, slag trapping chamber 7 is positioned at the below of filter cylinder 5, and wash-out valve 6 is arranged between slag trapping chamber 7 and the filter cylinder 5; Differential pressure pickup is installed on the interior outside of filter cylinder 5, the signal output part of differential pressure pickup is connected with the pressure difference signal input of electric controller, the cylinder control signal output of electric controller is connected with the control signal input of cylinder 1, the valve control signal output of electric controller is connected with the control signal input of wash-out valve 6, and the gas input of cylinder 1 is connected with the gas output end of air supply system.
As shown in drawings, in the use procedure, the impurity in the water constantly is deposited on the filter cylinder 5, makes the interior outside of filter cylinder 5 produce pressure reduction.The poor variation of inside and outside side pressure by differential pressure pickup monitoring filter cylinder 5, when pressure reduction reaches setting value, electric controller transmits operating instruction to cylinder 1 and wash-out valve 6, cause following action: cylinder 1 drives cleaning disk 3 by piston rod 2 and moves down, inboard to filter cylinder 5 is cleaned, wash-out valve 6 is opened filter residue is entered slag trapping chamber 7 simultaneously, whole cleaning process only need continue tens of seconds, when cleaning end, shifter cylinder 1 and wash-out valve 6, system returns to its original state, begins to enter next filter progress.
