Description
Technical field
The utility model relates to a kind of middle frequency furnace induction coil, especially relates to a kind of middle frequency furnace induction coil with separated magnetic effect.
Background technology
Induction coil is the most important part of middle frequency furnace, and its operating efficiency directly affects the performance of middle frequency furnace.In the prior art, the induction coil of middle frequency furnace comprises spiral induction coil and location-plate, and location-plate is through the distance between bolt location induction coil circle and the circle.In the middle frequency furnace course of work of prior art, the leakage field phenomenon can appear in the induction coil top, causes the circuit panel induction of induction coil top, and rubescent heating causes panel to melt when serious, influence the operate as normal of middle frequency furnace.The induction coil leakage field also can influence its service behaviour simultaneously.
Summary of the invention
The utility model is to the leakage field phenomenon that the induction coil of middle frequency furnace of the prior art occurs, and provides a kind of and can shield the magnetic field that induction coil makes progress, the induction coil with middle frequency furnace of separated magnetic effect.
For solving the problems of the technologies described above, the utility model is able to solve through following technical proposals:
A kind of middle frequency furnace induction coil comprises induction coil and location-plate, and location-plate is connected the outside of induction coil through bolt; It is characterized in that; Said induction coil top is provided with short-circuited conducting sleeve, and said short-circuited conducting sleeve is fixed on the upper end of location-plate, and and induction coil between be provided with the gap; Said short-circuited conducting sleeve inside is provided with dividing plate, and the both sides of outside short-circuited conducting sleeve, closing on dividing plate are respectively equipped with delivery port and water inlet.
In the technique scheme, the external diameter of said short-circuited conducting sleeve is identical with the external diameter of induction coil, and the clearance distance between short-circuited conducting sleeve and the induction coil and the turn-to-turn of induction coil are apart from identical.
In the technique scheme; Said short-circuited conducting sleeve is the annular pipeline that square copper pipe surrounds; This copper pipe two ends butt joint; And be provided for cutting off the dividing plate of copper pipe internal communication at joint, at short-circuited conducting sleeve arranged outside delivery port and water inlet, said delivery port and water inlet lay respectively at the both sides of closing on dividing plate.
Compared with prior art, above induction coil, add short-circuited conducting sleeve, can effectively prevent induction coil top leakage field, protection induction coil top device is normally moved, and improves the service behaviour of induction coil.

Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the cutaway view enlarged drawing at B place among Fig. 2.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Referring to Fig. 1, a kind of middle frequency furnace induction coil comprises induction coil 1; In induction coil 1 periphery several location-plates 3 are set; Location-plate 3 is fixedly connected on the outside of induction coil 1 through bolt 5, is used to keep the turn-to-turn distance of induction coil 1, makes not contact between induction coil 1 circle and the circle.
Induction coil 1 top is provided with short-circuited conducting sleeve 7, and this short-circuited conducting sleeve 7 is fixed on the upper end of location-plate 3 through bolt 5, and and induction coil 1 between keep gap 9, as preferably, this gap 9 is not less than the turn-to-turn distance of induction coil 1.
As preferably, the external diameter of this short-circuited conducting sleeve 7 is identical with the external diameter of induction coil 1, and gap 9 distances between short-circuited conducting sleeve 7 and the induction coil 1 and the turn-to-turn of induction coil 1 are apart from identical.Can effectively reduce the induction coil leakage field like this, at utmost protect the induction coil circumferential component normally to move.
In conjunction with Fig. 2 and Fig. 3; The annular pipeline that this short-circuited conducting sleeve 7 surrounds for square copper pipe; This copper pipe two ends butt joint; And be provided for cutting off the dividing plate 11 of copper pipe internal communication at joint, at short-circuited conducting sleeve 7 arranged outside delivery ports 21 and water inlets 23, delivery port 21 lays respectively at the both sides of closing on dividing plate 11 with water inlet 23.
As preferably, delivery port 21 outwards extends in parallel with the circumferencial direction of water inlet 23 along short-circuited conducting sleeve 7, and minimum spacing is smaller or equal to 10 centimetres between delivery port 21 and the water inlet 23.Can guarantee like this that when middle frequency furnace is worked the cooling water in the short-circuited conducting sleeve 7 can fully circulate, guarantee the radiating effect of short-circuited conducting sleeve 7.
When adopting the middle frequency furnace work of the utility model, induction coil 1 energising, inner water flowing; The electromagnetic action of its generation is in smelting furnace, and fusing is as for the metal of inside furnace, because the induction coil upper end is provided with short-circuited conducting sleeve 7; 7 water flowing no powers of short-circuited conducting sleeve; The electromagnetism that like this induction coil 1 is made progress cuts off, and the heat that short-circuited conducting sleeve 7 is produced by electromagnetic effect cools off through its inner recirculated cooling water, has effectively protected the equipment of induction coil top.Because the equipment of induction coil top the hot phenomenon of generating heat can not occur, the service behaviour of induction coil is provided, prolonged the working life of middle frequency furnace.
