Abstract
The utility model discloses a removing dregs type oil/water cooling device. A water inlet cooling water tube and a backwater cooling water tube are arranged in an oil cooling chamber; the oil cooling chamber is also provided with an arc water inlet flow guide tube (10), an arc backwater flow guide tube (11), an arc draining flow guide plate (12) and an arc draining flow guide tube. The utility model provides with a cooling water guide mechanism to make water flow smoothly; sand and mud and dregs in cooling water can be effectively removed away and exhausted with the water flow. The utility model overcomes the defects that the prior art exists dregs because of providing with a water chamber, and can eliminate unsafe factor caused by dregs effectively; the manual adding dregs experiment of the practical example proves the reliable performance of the removing dregs. The utility model has the advantages of easy use and convenient operation, and which is suitable for the oil cooling of the cooling work of large and medium transformers particularly.
Description
The utility model relates to the device that water cools off heat content oil.The oil-water refrigerating mechanism of using as transformer.
The patent No. is that 88218729.5 utility model patent and application number are that a kind of " enclosed dual-expansion mounth oil-water cooler " put down in writing in 88105817.3 application for a patent for invention simultaneously, and its technical scheme is seen Fig. 1.This oil-water refrigerating mechanism has oil cooling chamber ［ 1 ］, intake chamber ［ 2 ］, upper tank ［ 3 ］ and drip chamber ［ 4 ］; Into water cooling water pipe ［ 5 ］ and backwater cooling water pipe ［ 6 ］ are arranged in the oil cooling chamber ［ 1 ］; The water inlet cooling water pipe is communicated with intake chamber and upper tank, and the backwater cooling water pipe is communicated with upper tank and drip chamber.High temperature oil enters the oil cooling chamber by import, and cooling water flows into upper tank by intake chamber through the water inlet cooling water pipe, flows into drip chamber by upper tank through the backwater cooling water pipe again, discharges then.Cooling water flow carries out heat exchange by cooling water tube wall and heat content oil when cooling water pipe, heat is taken away, and makes it the cooling cooling, and cooled low temperature oil is flowed out by outlet, equipment (transformer) the circulation cooling of supply and demand cooling.Shown in Figure 1 is the two expanding mouth type structures with expand mouthful ［ 7 ］, bloated mouthful ［ 8 ］, and bloated mouth is used to prevent oil, seepage.Enclosed isolation ward ［ 9 ］ is arranged between the oil cooling chamber of the oil-water refrigerating mechanism of two expanding structures and the hydroecium, and this isolation ward can prevent that work from mixing because of seepage causes profit with oil, water; The bloated mouthful oil-water refrigerating mechanism of existing list does not have the enclosed isolation ward, has only expand mouthful ［ 6 ］.The oil-water refrigerating mechanism of the bloated mouth of existing list or two bloated mouth structures, cooling water all is at first to flow into intake chamber by water inlet pipe, flows into upper tank through the water inlet cooling water pipe then, flows into drip chamber by upper tank through the backwater cooling water pipe again; Discharge then.Owing to have the current dead angle in each hydroecium, the problem of Chan Shenging is in actual use, the silt particle that contains in the cooling water, disintegrating slag repertory in each hydroecium seriously stops up, and especially the flood season, the interior accumulated slag of oil-water refrigerating mechanism that is used for high-power transformer is very serious, need frequent slag reason, because the scarfing cinder number of times is frequent, every cleaning once all need be carried out two end cap dismounting, and required time is longer, operating difficulties, the equipment that influences runs well.
The purpose of this utility model provides a kind of residuum discharging type oil and water cooler.This oil-water refrigerating mechanism can be eliminated inner accumulated slag phenomenon.
Technical scheme is as follows:
Fig. 2 is the technical scheme structure chart, and Fig. 3 is the A-A view of Fig. 2, and appointment Fig. 2 is the specification digest accompanying drawing.
The technical scheme of dealing with problems is, one, and the intake chamber of cancellation prior art is provided with arc water inlet mozzle ［ 10 ］, and this mozzle one end is repeatedly kicked into water pipe, and the other end is repeatedly kicked into the water cooling water pipe; Its two, the cancellation upper tank is provided with arc backwater mozzle ［ 11 ］, this mozzle one end is repeatedly kicked into the water cooling water pipe, the other end water cooling water pipe that is linked back; Its three, arc draining flow deflector ［ 12 ］ or arc draining mozzle (expression in the accompanying drawing, its version is with the arc mozzle of intaking) are set, when being arc draining mozzle, this mozzle one end water cooling water pipe that is linked back, other end platoon water pipe.Owing to be provided with arc water inlet mozzle, arc backwater mozzle, arc draining flow deflector or arc draining mozzle, eliminated the current dead angle, the silt particle in the cooling water, disintegrating slag are promptly discharged with current, thereby eliminate the accumulated slag phenomenon.
Embodiment.Fig. 4 is the schematic structure diagram (and referring to Fig. 2) of embodiment, and Fig. 5 is the B-B profile of Fig. 4.Present embodiment is except that pressing structure fabrication shown in Figure 2, establish water supply connector ［ 13 ］ at the water inlet pipe place, water supply connector ［ 13 ］ is provided with blowoff valve ［ 14 ］ and side direction low discharge water inlet pipe ［ 16 ］, blowoff valve is used for the accumulated slag discharging in the water supply connector, turning valve rod ［ 15 ］ just can make valve opening or close, simple to operate, convenient, the scarfing cinder required time is short, can improve equipment operating efficiency greatly, and the effect of lateral intake pipe is set two, the one, the slag that enters in the joint is seethed, with flow, prevent accumulated slag, the 2nd, be used to clean water supply connector, when ending cooling water, connect water inlet pipe ［ 16 ］, when opening blowoff valve, can clean water supply connector.The arc of present embodiment water inlet mozzle and arc draining flow deflector are installed by lower body, and lower body is with after the oil cooling chamber is connected, and this locates water route connection; Arc backwater mozzle is loaded on upper machine body, and upper machine body is with after the other end of oil cooling chamber is connected, and each water pipe promptly is communicated with.Adopt such structure, be convenient to making regular check on and changing of each mozzle.Present embodiment is used for the cold oil cooling of transformer, 120 kilowatts of specified cooling capacities, long-pending 13.5 square metres of active cooling surface, per hour 12 cubic metres of specified discharges.Manually intentional refinement sand test in cooling water to embodiment carries out does not have long-pending sand phenomenon in the cooling device, the evidence deslagging is functional.
The utility model is by being provided with deflector, make current smooth and easy, overcome the shortcoming of the easy accumulated slag of prior art, can improve equipment operating efficiency greatly, eliminated the unsafe factor that causes because of accumulated slag more effectively, when being used for big-and-middle-sized transformer work oil cooling but the time, effect is particularly outstanding, also can be used for the profit cooling of other similar devices.
