Description

Pneumatic fast quick change stove switch
Technical field
What the utility model technology related to is a kind of pneumatic fast quick change stove switching device that is used for the intermediate frequency coreless induction furnace, belongs to intermediate frequency coreless induction furnace technical field.
Background technology
Intermediate frequency coreless induction smelting system generally will be made up of a cover intermediate frequency power supply and two smelting furnaces, one cover intermediate frequency power supply can only be to one of them body of heater power supply melting, when body of heater needs the cupola drop lining or breaks down maintenance, enable another body of heater, need to switch with fast quick change stove switch.Another kind of situation be two cover power supplys simultaneously to two bodies of heater power supplies, a cover intermediate frequency power supply plays the melting effect, another set of intermediate frequency power supply plays insulation effect, also need be with fast quick change stove switch in the time will switching mutually.But present above-mentioned switching one is with manual switching (accounting for the overwhelming majority), the 2nd, and the stove switch is moved in electricity consumption.It is long to change the stove time during manual switching, and efficient is low, and labour intensity is big.And use the electronic stove switch that changes, and because of intermediate frequency power supply can produce magnetic field when the work to can eddy-current heating near the metal of energising part, metal mechanical elasticity pressure is weakened, also can cause stand stretch, cause the contact site loose contact and burn.
Summary of the invention
The purpose of this utility model provides a kind of easy to use, reliable pneumatic fast quick change stove switching device, it is used for the intermediate frequency coreless induction furnace, has not only improved intermediate frequency coreless induction furnace security performance in use, and has improved the production effectiveness of stove.
Pneumatic fast quick change stove switch comprises static block 10,20 two mutually insulateds, that join with the both positive and negative polarity of power supply respectively, and two cylinders 15,16,25,26 are respectively being arranged above the static block 10, below static block 20; A cylinder 15 of top is coaxial with a cylinder 25 of below, and another cylinder 16 of top is coaxial with another cylinder 26 of below; On the cylinder rod of four cylinders 15,16,25,26, respectively be connected with movable block 11,12,21,22; Movable block 11,21 is connected with the cable of a smelting furnace respectively; Movable block 12,22 is connected with the cable of another smelting furnace respectively; It also comprises the control device that is used to control each cylinder action; Under the drive of cylinder, when movable block 11,21 contacted with static block 10,20 respectively, movable block 12,22 separated with static block 10,20 respectively; When movable block 12,22 contacted with static block 10,20 respectively, movable block 11,21 separated with static block 10,20 respectively.
Its course of work: when cylinder 15, the 25 synchronous air inlets of working chamber, movable block 11,21 closes simultaneously with static block 10,20 respectively, and a smelting furnace energising can be worked, the synchronous exhaust of cylinder 16,26 working chambers simultaneously, another smelting furnace disconnection work.Otherwise when cylinder 16, the 26 synchronous air inlets of working chamber, movable block 12,22 and static block 10,20 close simultaneously, and above-mentioned another smelting furnace energising can be worked the synchronous exhaust of cylinder 15,25 working chambers simultaneously, an above-mentioned smelting furnace disconnection job.
It is simple and easy, simple to operate, easy to use, reliable that the utility model is made, and both shortened and change the stove time than manually changing stove, improved effectiveness, alleviated working strength of workers again.Than the electronic stove switch that changes better contact is arranged; Use electronicly when changing the stove switch,, metal mechanical elasticity pressure is weakened, produce stand stretch, cause the contact site loose contact because of intermediate frequency can produce the metal induction heating of magnetic field to close energising part when the work; And use this pneumatic fast quick change stove switch, because two cylinders up and down are on same axis, two cylinders form the top up and down, be exactly stand stretch, can both guarantee contact contact-making surface constant voltage, electric conductivity is constant, can loose contact and burn out, so can use not fragile for a long time.
As further improvement, in the static block 10,20, in the movable block 11,21,12,22 cooling-water duct that is communicated with water is respectively arranged all.Logical cooling water in cooling-water duct can be to the fully cooling of static block, movable block (contact).
Description of drawings
Fig. 1 is the structural representation that the utility model embodiment is connected with smelting furnace.
The specific embodiment
Among Fig. 1, pneumatic fast quick change stove switching device comprises frame 3, be arranged on four cylinders 15,16,25,26 and epoxy resin board 5 on the frame 3, control the control device 4 of each cylinder action.
And use the epoxy resin board mutually insulated between two static blocks 10,20 that the both positive and negative polarity of power supply joins.Cylinder 15,16 is above static block 10, and cylinder 25,26 is below static block 20; Cylinder 15,25 is coaxial, and cylinder 16,26 is coaxial.
