Abstract
The invention discloses a self-cleaning filter which comprises a spray system water pump; the self-cleaning filter contains a substrate, the central axis of the substrate is provided with a through hole, the through hole is subjected to necking at upper and lower flanges of the substrate so as to form a cavity of the substrate, and a lamellar filter screen is arranged in the cavity and divides the cavity into a filtering chamber and a purifying chamber; and the side wall of the substrate is provided with a waste residue diversion port, and the side wall is provided with a waste residue collector. According to the invention, because water flows and an obliquely-distributed lamellar filter screen are fully used, the directional flow of waste residues can be guided, so that the self-cleaning filter concurrently has a function of automatic residue removal.
Description
Technical field
The present invention relates to a kind of filter, particularly relate to the automatically cleaning filtration system of a kind of self-cleaning filter and composition thereof.
Background technology
The spray system of humid air cooler is due to the outdoor work of equipment, in addition the iterative cycles of shower water uses, make that shower water impurity content is comparatively large, medium degree of purity is not high, so not only directly affect the performance of equipment exchange capability of heat, and very easily cause the blocking of nozzle.
The formation such as the water tank of spray system primarily of retaining, the water pump as power source, spray pipe, nozzle of humid air cooler.After water tank stores a certain amount of water, under the effect of water pump, water flows into spray pipe by water tank through water pump, then is sprayed by nozzle, forms the atomization globule.The effect of atomization reduces the temperature of environmental air on the one hand, and the evaporation latent heat that make use of the globule on the other hand reduces the temperature of tube sheet, thus makes cooler realize the function of cooling medium.Water in water tank is running water, due to cool tube sheet thus moisture content can lose, so need regularly to add running water in water tank, under normal circumstances from the beginning impurities in water seldom, impurity can not be introduced water tank by water source as can be seen here; Because water tank upper is coated with screen pack, so the house refuses such as the shredded paper of sheet, polybag are difficult to enter water tank; After humid air cooler is installed and gone into operation, usually can carry out cleaning works thoroughly, because equipment is huge, complex structure, thus can carry into welding slag, iron that some production processes produce unavoidably secretly and the impurity such as cut; In addition, equipment is in the long-term course of work, and due to washing away of current, part paint likely can peel off and enter water tank; Equipment is operated in open air, and on account of the weather, the rubbish such as sandstone, deadwood and rotten leaf likely can be scraped into water tank by wind and rain.All these impurity all likely enter spray system by water tank, and the lighter blocks single or several nozzle, and heavy then blocking spray pipe causes the paralysis of whole spray system.
Above by the analysis of originating to shower water impurity, at pump intake place, filter should be installed as seen.The slag class impurity that the rubbish that production process produces, environmental debris and particle are larger, can the mode of general interpolation simple filtration net process, due to impurity particle out-of-shape, even if pile up on screen pack, still can there is certain gap between particle, thus can not produce larger impact to the water inlet of spray system.Short grained impurity on the contrary, once pile up, because intergranular gap is little, on the impact of spray system and harm larger.
Summary of the invention
The object of the present invention is to provide a kind of can the filter of particulate contamination and the automatically cleaning filtration system of composition thereof in automated cleaning water, to improve the serviceability of equipment, ensure the reliability service of humid air cooling arrangement.
For this reason, the technical scheme adopted is: a kind of self-cleaning filter, comprise spray system water pump, described self-cleaning filter comprises matrix, the axis of this matrix has through hole, this through hole forms the cavity of matrix in the upper and lower flange constriction of matrix, is provided with chip screen pack described cavity is divided into filter chamber and clean room in this cavity; The sidewall of described matrix has waste residue flow-guiding mouth, and this sidewall installs waste residue collector.
The axis of described screen pack and described matrix is at 45 ° ~ angle of 75 °.
The steel wire of described chip screen pack is made up of above-listed steel wire and lower row's steel wire, and both are welded into entirety.
The outside of described waste residue flow-guiding mouth is provided with upper and lower water conservancy diversion groove.
Screen pack is installed at the sewage draining exit place of described waste residue collector.
The front and rear end of described matrix is through, and seals described matrix with removable cover.
Described self-cleaning filter is arranged on the water outlet of spray system water pump, and grade one filter is arranged on the water inlet of spray system water pump.
Described grade one filter is made up of flange and spherical filter net.
Described self-cleaning filter is multiple to be arranged in series, and wherein the grid order number of chip screen pack reduces successively or increases.
A kind of self-cleaning filter involved in the present invention, achieves the automation mechanized operation of filtration, reduces the artificial input of equipment, ensure that the normal performance of spray system cooling effect, ensure that the normal operation of equipment.This self-cleaning filter manufacturing cost is not high simultaneously, without the need to increasing other auxiliary power-equipments.
The involved in the present invention automatically cleaning filtration system be made up of self-cleaning filter, be different from the processing mode of adding simple filtration net, it makes full use of the current of water pump generation as power, single filter ball is installed water pump water inlet by the source according to impurity particle, self-cleaning filter is arranged on the pump outlet place of spray system, adopt the mode process water inlet of classified filtering, by the interception of particle the greater outside single filter ball.By to spray system harm more greatly, not easily or cannot by the granule impurity of simple filtration net filtration, the slideway that the chip screen pack utilizing the inertia of water and ramped shaped to arrange is formed, therefrom be separated, automatically discharge water tank by granule impurity, practice shows that the present invention can solve the problem well.
The present invention is applicable to the spray system of humid air cooler or the spray system of other industry equipment of the industry such as petroleum and petrochemical industry, nuclear power thermoelectricity, also can be used for sewage disposal.
