Abstract
The spiral plate type strong oil water cooler for electric furnace transformer includes main parts of stainless steel spiral plate type cooler, and is characterized by that on the bottom surfaces of water inlet pipe and oil outlet pipe respectively a funnel-shaped through hole whose bottom end is connected with sewage discharge valve is set, and between two adjacent rolling plates in the spiral plate type heat exchanger a square rack supporting bar whose two ends are welded is alternatively clamped, and the included angle between the bottom edge connecting line of supporting bar and horizontal line is less than 90 deg. The brace rod has few welding points and few deposited residues, and can be conveniently discharged, the medium is fully stirred due to the impact action of the brace rod, the cooling effect is further improved, the residues are reduced, the heat exchanger is made of carbon steel, the manufacturing cost is reduced by 2/3, and the work is safe and reliable.
Description
The utility model relates to the heat-exchange apparatus that a kind of heat exchange medium does not directly contact, particularly a kind of furnace transformer spiral plate type oil water cooler.
At present, the type of cooling of taking during high-power transformer work has oil, air-cooled, forced oil circulation water-cooling, oil and air-cooled influenced by ambient temperature big, arc furnace, ore heat furnace transformer generally adopt the forced oil circulation water-cooling mode, to adapt to the operational environment of high temperature.And the heat exchanger that now is used for water-cooled all is to adopt shell and tube and two kinds of versions of stainless steel spiral plate type, the former is owing to the reason of manufacturing process, in the junction, termination of tubulation seepage takes place easily, water is sneaked in the transformer oil and cause the accident, and there is a dead angle of media flow, easy vat waste, blocking pipeline; Welding cylindrical shape fixed block makes adjacent two plates keep the method for even distance to the latter on spiral plate owing to adopting, the welding slag of circular commissure is difficult to thorough removing, thereby generation hidden danger, simultaneously, medium is along spiral plate face PARALLEL FLOW, inside can not fully be stirred, and radiating effect can not further improve.
The purpose of this utility model is in order to overcome above-mentioned weak point, and a kind of further raising cooling effect is provided, and the residue in the medium is difficult for deposition, it is convenient to remove, and cost is low, safe and reliable furnace transformer spiral plate type oil water cooler.
The purpose of this utility model is achieved in that furnace transformer comprises base with the spiral plate type oil water cooler, water inlet pipe, outlet pipe, oil inlet pipe, flowline, oil pump, control cabinet, spiral heat exchanger, water pressure gauge, oil pressure gauge, water-thermometer, oil temperature gauge, it is characterized in that in water inlet pipe behind the filter screen, on the pipe bottom surface in the flowline before the filter screen funnel-shaped hole is arranged respectively, the through hole bottom is connected with sewage draining valve respectively, the side's of accompanying tooth bar strut respectively between adjacent two roll bendings in the spiral heat exchanger, the strut plane of bending is vertical with the roll bending face, two ends are welded on the roll bending by the inside, and base line and horizontal angle are less than 90 °.
Fig. 1 is the utility model structural representation.
Fig. 2 is the strut scheme of installation;
Fig. 3 is a strut shape schematic diagram.
Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.
With BYSLI type 40m
2Product is an example, and furnace transformer comprises base 1, water inlet pipe 2, outlet pipe 3, oil inlet pipe 4, flowline 5, oil pump 6, control cabinet 7, spiral heat exchanger 8, water pressure gauge 9, oil pressure gauge 10, water-thermometer 11, oil temperature gauge 12 with the spiral plate type oil water cooler.Have a upper port diameter to be not less than the funnel-shaped hole 15,16 of caliber twice respectively on the pipe bottom surface before the filter screen 14 in filter screen 13 backs, the flowline 5 in water inlet pipe 2, the through hole bottom is connected with sewage draining valve 17,18 respectively.Every alternate 200mm accompanies the square tooth bar strut of being made by diameter 6mm round steel 19 between adjacent two roll bendings in the spiral heat exchanger 8, strut 19 plane of bendings are vertical with the roll bending face, two ends are welded on the roll bending by the inside, 25 ° of base line and horizontal angles, side facewidth 100mm, high 18mm, heat exchanger selects for use carbon steel to make.Water inlet pipe 2, outlet pipe 3 connect the two ends of cooling water pipeline in the spiral heat exchanger 8 respectively, the efferent duct of oil pump 6 connects oil inlet pipe 4, oil inlet pipe 4 other ends, flowline 5 connect the two ends on spiral heat exchanger 8 inner oil tube roads respectively, and oil pump 6, control cabinet 7 are directly fixing, spiral heat exchanger 8 is fixed on the base 1 by installing rack.
The utility model is owing to adopt above architecture advances, and the pad of square tooth bar strut 19 is few, and the residue chance that is deposited in the pipeline significantly reduces, and can by on connect funnel-shaped hole 15,16 sewage draining valve 17,18 discharge the residue in the pipeline is convenient.Because the counterattack effect of square tooth bar strut 19, make medium stirrings of fully rolling when medium flows in pipeline, further improved cooling effect and reduced the deposition of residue.Spiral heat exchanger 8 selects for use carbon steel to make, and cost is compared the cooler that adopts the stainless steel spiral heat exchanger and reduced by 2/3, and is safe and reliable.
