Abstract
A kind of cooling water filter, is made up of filter body, gland assembly, filter screen and seal.Filter body is welded by housing, water outlet short circuit, water-output flange, blow-off pipe, blowdown flange, shell flange; Gland assembly comprises gland body, slide block, spring, spring shim, gland flange.Compact conformation of the present invention, processing technology is simple, and in use procedure, only regularly need open the impurity of deposition in blowoff valve discharge filter, while blowdown, cooling water rinses filter screen inwall, and blowdown and filter gauze cleaning process do not need to dismantle filter.
Description
Technical field:
The present invention relates to the cooling device of large-capacity power transformer, be specifically related to the cooling water filter of strong recycle oil-water cooler.
Background technology
Large-capacity power transformer generally uses strong recycle oil-water cooling to dispel the heat, and its cooling water used has to pass through sofening treatment removal calcium ions and magnesium ions wherein, thus avoids the calcium ions and magnesium ions of cooling water to affect heat transfer effect in heat exchange tube wall deposition.In the sofening treatment process of cooling water, first must use the solid impurity in filter filtering Natural Water, then carry out ion-exchange treatment by ion bed.Cooling water filter in cooling water softening treatment facility after long-term use, impurity in Natural Water can block filter screen, add the flow resistance of cooling water, and reduce filter effect, when be embedded in the solid particle on filter screen by current scour by filter screen after enter transformer cooler, also can cause heat-exchange tube of cooler fouling, reduce the heat transfer effect of transformer cooler.For ensureing the filter effect of cooling water filter; need regularly to carry out desilting and filter gauze cleaning to filter; filter in conventional transformer cooling-water treatment apparatus must shut down when carrying out desilting and filter gauze cleaning after by under dismounting filter, just can carry out desilting and cleaning.Invention " pipeline filtration equipment for industrial water " (inventor: Su Fenlian, Zhang Lixin, Authorization Notice No.: CN2259938Y) provide a kind of filter be arranged on pipeline, this device regularly must open gland desilting and cleaning filter screen, this invention must not dismantle whole filter, but still need take the gland of filter apart.
Summary of the invention:
The object of invention to provide a kind of needs to dismantle the cooling water filter that just can carry out blowdown and filter gauze cleaning.
Technical scheme: a kind of cooling water filter, comprises filter element, gland assembly, filter screen, seal, filter element comprises housing, water outlet short circuit, water-output flange blow-off pipe, blowdown flange, shell flange, housing is in " U " shape, and a hole is arranged at bottom, its diameter is consistent with the hole size of water outlet short circuit hollow, water-output flange and housing are fixed together by water outlet short circuit, and the blue hollow space of water law communicates with water outlet short circuit hollow space, and shell flange is passed through at the top of shell nozzle, gland flange is fixedly connected with the gland body outer wall in gland assembly, and gland body bore is less than the diameter of shell nozzle, and gland assembly is wine cup shape, and from being hollow to the middle part of rim of a cup at the bottom of cup, gland assembly comprises gland body, slide block, spring, gland flange, is provided with water-in flange at the bottom of cup, and water-in flange hollow space is connected with gland assembly hollow space, gland assembly wall of cup is provided with the cannelure of opening, and annular groove bottom is provided with spring, upper placement gasket seal, pad is provided with slide block, filter screen one end connection sliding block, the other end is positioned at housing hollow and connects blow-off pipe, and blow-off pipe to go directly space outerpace through housing wall, and blow-off pipe one end outside housing is fixed with blowdown flange.
Gasket seal is provided with between shell flange, gland flange.
Spring shim is provided with between spring and gasket seal.
Filter screen two is provided with gasket seal.
Blow-off pipe one end outside housing is provided with blowoff valve.
Implement beneficial effect of the present invention: compact conformation of the present invention, processing technology is simple, in use procedure, only regularly need open the impurity of deposition in blowoff valve discharge filter, while blowdown, cooling water rinses filter screen inwall, and blowdown and filter gauze cleaning process do not need to dismantle filter.Accompanying drawing explanation

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
Cooling water filter structure as shown in Figure 1, is made up of filter body, gland assembly, filter screen 8 and seal.Filter body is welded by housing 3, water outlet short circuit 2, water-output flange 1, blow-off pipe 4, blowdown flange 5, shell flange 9; Gland assembly comprises gland body 16, slide block 18, spring 15, spring shim 14, gland flange 11.
Water outlet short circuit 2 one end is welded with water-output flange 1, and the other end is together with housing 2 bottom welding; Housing 2 openend is welded with shell flange 9; Blow-off pipe 4 one end is welded with blowdown flange 5, after the other end inserts housing 3 by the hole of housing 3 side and housing 3 weld together, water-output flange 1, water outlet short circuit 2, housing 3, shell flange 9, blow-off pipe 4, blowdown flange 5 are welded into filter body by the way.
Cannelure inner bottom part mounting spring 15 on gland body 16, above spring, mounting spring pad 14, gasket seal 1, install slide block 18 above gasket seal.
Filter screen 8 is installed between blow-off pipe 4 and slide block 18, and filter body is connected by shell flange 9, gland flange 11 with gland assembly.
Filter accesses cooling water pipeline by water-in flange 1, water-output flange 17, and when normally running, cooling water flows into from the through hole of gland body 16, and after filter screen 8 filters, just water outlet short circuit 2, water-output flange 1 flow out, and the solid impurity in cooling water is deposited in blow-off pipe 4.
During cleaning blowdown, open blowoff valve 6, cooling water washes away filter screen 8 inwall, by solid impurity through blow-off pipe 4, blowoff valve 6 discharge filter.
