Abstract
The utility model comprises water inlets, a water chamber and water outlets. A slim water channel connected to the water inlets is equipped, and an ejector nozzle is opened at the slim water channel. A baffle plate is equipped at the water chamber and separates the influent water of cooling water from the effluent water of the cooling water. The water inlets and the water outlets are equipped at the two sides of a leading wire port and a wire outlet of a stirrer. The cooling system changes the original water flow which can only be in axial motion, the rotary motion along the inner wall of the stirrer is added, a baffle plate is added, the influent water and the effluent water are separated, defects such as local overheating of a coil caused by the short circuit of water in the past, etc. are avoided, and the service life of the coil is extended. Especially the positions of the water inlets and the water outlets equipped causes the leading wire of the stirrer to be cooled well, and the damage of the stirrer caused by the overheating of the leading wire joint is avoided.
Description
Technical field
The utility model relates to a kind of water-cooling apparatus that is used for the external magnetic stirrer of metallurgical continuous casting.
Background technology
Magnetic stirrer is widely used on the metallurgical continuous casting equipment, and it can improve billet quality comprehensively, but magnetic stirrer can not reach designing requirement service life at present.Cause agitator coil low reason in service life that following two aspects are arranged, each steel mill of the first uses water-quality ratio relatively poor, the electrical conductivity height; It two is that the cooling effect of agitator own is not good.Improve agitator water circulation, reducing coil temperature preferably, improving coil service life is the cardinal task of pendulum in each magnetic stirrer manufacturer.
At present, the most number average of the conticaster magnetic stirrer of manufacturing both at home and abroad adopts coil directly to immerse the mode of cooling off in the cooling water.Its type of cooling is to make cold water encircle (porous water ring) after the radially outflow of hydroecium from water inlet, rises vertically again.Flow out through the through delivery port of coil.Certain part of coil particularly easily forms the cooling dead band in the end like this, causes over-heat inside, and coil is also many to be damaged herein.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides a kind of can produce rotary water current, improves the magnetic stirrer cooling device of circulating effect.
The utility model is that the technical scheme that its problem of solution is adopted is: the magnetic stirrer cooling device comprises water inlet, hydroecium and delivery port, connects water inlet and is provided with long and narrow water channel, has spout at long and narrow water channel; Be provided with baffle plate at hydroecium, the water inlet of cooling water and water outlet are separated.Water inlet, delivery port are arranged on that agitator draws, the line outlet both sides.
The beneficial effects of the utility model are: produce novel rotary water current structure, improve circulating effect comprehensively, the minimizing cooling water washes away coil, increases the service life of coil, avoids the coil hot-spot.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, water inlet, 2, delivery port, 3 long and narrow water channels,, 4 spouts,, 5, hydroecium, 6, baffle plate.
The specific embodiment
Realize that as shown in Figure 1 the magnetic stirrer cooling device of novel water flow structure is made up of water inlet 1, long and narrow water channel 3, spout 4, hydroecium 5, baffle plate 6 and delivery port 2.Entery and delivery port is arranged on that agitator draws, the line outlet both sides, can guarantee that the lead-out wire cooling is good, in endless form, add dividing plate 6, its effect is that the water inlet of cooling water and water outlet are separated, avoided Inlet and outlet water that mixed water (being the water route short circuit) phenomenon is arranged like this, make cooling water flow out hydroecium again behind the cooling coil fully effectively, dividing plate 6 should be done so that as possible that water-in and water-out effectively isolate, so generally do according to the structure of iron core and hydroecium inner chamber.Use 3240 plates comparatively suitable, 3240 plates can insert in the fixed slot,
Cooling water enters from water inlet 1, by long and narrow water channel 3, cooling water produces high pressure in water channel, penetrate by spout 4, the water that enters hydroecium begins to move upward, and the heat of coil is taken away, because 3 terminal spout 4 effects of long and narrow water channel, water generates in the hydroecium is rotatablely moved, avoided the overheated generation of end turn.Long and narrow water channel 3 and spout 4 are the bases that produce rotary water current, and water channel, vent material are selected the thick not magnetic conduction of 1.5mm steel for use, through machine-shaping, are welded.Determine long and narrow water channel gap and spout 4 opening sizes according to the agitator capacity.Spout 4 will be placed on the gap location of two coils not over against coil and magnetic pole, and the current of ejection can be injected between coil in the water seam, and this kind structure is cooling coil fully, is a kind of preferably type of cooling.
Claims (2)
1, a kind of magnetic stirrer cooling device comprises water inlet (1), hydroecium (5) and delivery port (2), it is characterized in that: connect water inlet (1) and be provided with long and narrow water channel (3), have spout (4) at long and narrow water channel (3); Be provided with baffle plate (6) at hydroecium (5), the water inlet of cooling water and water outlet are separated.
2, magnetic stirrer cooling device according to claim 1 is characterized in that: water inlet (1), delivery port (2) are arranged on that agitator draws, the line outlet both sides.
