Description
Technical field
The utility model relates to a kind of filter, particularly relates 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, the iterative cycles of shower water uses in addition, make that the shower water impurity content is large, the 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 obstruction of nozzle.
The water tank that the spray system of humid air cooler is mainly used by retaining, the water pump as power source, spray pipe, nozzle etc. consist of.After water tank held a certain amount of water, under the effect of water pump, water flowed into spray pipe by water tank through water pump, then by the nozzle ejection, formed the atomizing globule.The effect of atomizing has reduced the temperature of environmental air on the one hand, has utilized on the other hand the evaporation latent heat of the globule to reduce the temperature of tube sheet, thereby has made cooler realize the function of cooling medium.Water in water tank is running water, and owing to wanting cooling tube sheet thereby moisture content to lose, so need regularly add running water in water tank, in running water, impurity seldom, this shows that the water source can not introduce water tank with impurity under normal circumstances; Because water tank upper is coated with screen pack, so the house refuses such as large stretch of shredded paper, polybag are difficult to enter water tank; After the humid air cooler install to be gone into operation, usually can carry out cleaning works thoroughly,, complex structure huge due to equipment, thereby can carry into unavoidably welding slag, iron that some production processes produce 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 might peel off and enter water tank; Equipment is operated in the open air, and on account of the weather, wind and rain might blow rubbish such as sandstone, deadwood and rotten leafs into water tank.All these impurity all might enter spray system by water tank, and the lighter stops up single or several nozzles, and are heavy stop up the paralysis that spray pipe causes whole spray system.
Above-mentioned by the analysis to shower water impurity source, as seen should filter be installed at the pump intake place.The larger slag class impurity of rubbish, environment rubbish and particle that production process produces, mode that can general interpolation simple filtration net is processed, due to the impurity particle out-of-shape, even pile up on screen pack, still can there be certain gap between particle, thereby can not produce larger impact to the water inlet of spray system.Short grained impurity on the contrary, in case pile up, because intergranular gap is little, larger on impact and the harm of spray system.
The utility model content
The purpose of this utility model be to provide a kind of can automated cleaning water in the filter of particulate contamination and the automatically cleaning filtration system of composition thereof, to improve the serviceability of equipment, guarantee the reliability service of humid air cooling arrangement.
For this reason, the technical scheme that adopts is: a kind of self-cleaning filter, comprise the spray system water pump, described self-cleaning filter comprises matrix, have through hole on the axis of this matrix, this through hole consists of the cavity of matrix in the upper and lower flange constriction of matrix, be provided with the chip screen pack in this cavity described cavity is divided into filter chamber and clean room; Have the waste residue flow-guiding mouth on the sidewall of described matrix, and on this sidewall, waste residue collector is installed.
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 of above-listed steel wire and lower row's steel wire, and both are welded into integral body.
The outside of described waste residue flow-guiding mouth is provided with upper and lower water conservancy diversion groove.
Sewage draining exit place's installation screen pack of described waste residue collector.
The front and rear end of described matrix connects, 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 comprised of flange and spherical screen pack.
A plurality of series connection settings of described self-cleaning filter, wherein the grid order number of chip screen pack reduces successively or increases.
A kind of self-cleaning filter that the utility model is related has been realized the automation mechanized operation of filtering, and has reduced the artificial input of equipment, has guaranteed the normal performance of spray system cooling effect, has guaranteed the normal operation of equipment.This self-cleaning filter manufacturing cost is not high simultaneously, need not to increase other auxiliary power-equipments.
The automatically cleaning filtration system that is formed by self-cleaning filter that the utility model is related, be different from the processing mode of adding the simple filtration net, it takes full advantage of the current of water pump generation as power, according to the source of impurity particle, the single filter ball is installed water pump water inlet place, self-cleaning filter is arranged on the pump outlet place of spray system, adopt the mode of classified filtering to process water inlet, particle the greater is tackled outside the single filter ball.Will be large to spray system harm, be difficult for or can't be by the granule impurity of simple filtration net filtration, utilize the slideway of the inertia of water and the chip screen pack formation that ramped shaped is arranged, granule impurity is therefrom separated, automatically discharges water tank, and practice shows that the utility model can address the above problem well.
The utility model is applicable to the spray system of humid air cooler of the industries such as petroleum and petrochemical industry, nuclear power thermoelectricity or the spray system of other industry equipment, also can be used for sewage disposal.
