Abstract
The invention relates to the melting furnace technology and aims to provide a dustproof structure of a medium-frequency induction melting furnace. The dustproof structure comprises a dust baffle, a mounting rack, a support bar, a connecting bar, and a fixed bar. The mounting rack is fixed below a furnace shell cover plate of a furnace body. The upper edge of the dust baffle is movably mounted on the mounting rack. The side, facing to the furnace body, of the dust baffle is provided with a projecting part which is movably connected with one end of the support bar. The other end of the support bar is movably connected with one end of the connecting bar. The other end of the connecting bar is movably connected with the end of the fixed bar. The connecting bar is bent. The fixed bar is fixed on a furnace shell large support below the surface body. When the furnace tilts, the furnace body rotates around a shaft point under the action of a cylinder, the connecting bar leaves a furnace frame support, the dust baffle attaches to the furnace body, and conducting power can be avoided entering the furnace body; when the furnace restores, the furnace body reversely rotates around the shaft point under the action of the cylinder, the connecting bar presses against the furnace frame support, the support bar supports the dust baffle, space is reserved, and daily maintenance and furnace repair are facilitated.
Description
Technical field
The present invention relates to smelting furnace technology, be specifically related to a kind of dustproof construction of medium frequency induction melting furnace.
Background technology
The dust excluding plate of medium frequency induction melting furnace is to enter body of heater in order to stop and to reduce conduction dust, prevents body of heater generation spark phenomenon, reserves again the useful space, is convenient to regular maintenance and repairing.Existing medium frequency induction melting furnace has roll type and two kinds of structures of frame-type.Roll type medium frequency induction melting furnace possesses and prevents from conducting electricity the function that dust enters body of heater, but when break down in body of heater inside, need to split whole body of heater and keep in repair, therefore roll type structure should not popularize.General medium frequency induction melting furnace adopts tower structure, but the shortcoming of tower structure is, when smelting furnace turndown, body of heater turns 95 ° by bearing block, the conduction dust accumulating on the dust excluding hood of body of heater top is because the effect of wind and hot gas falls, fall into induction coil turn-to-turn and magnetic and grip inner side, formula body of heater accumulation conducting powder dirt, causes body of heater to occur spark phenomenon.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes deficiency of the prior art, and a kind of dustproof construction of medium frequency induction melting furnace is provided.
For technical solution problem, solution of the present invention is:
The dustproof construction that a kind of medium frequency induction melting furnace is provided, comprises dust board; Also comprise installing rack, support bar, connecting rod and fixed bar; Wherein, installing rack is fixedly installed on the furnace shell cover plate downside of body of heater, and the upper edge of dust board is movably installed on installing rack; At dust board, on the side of body of heater, be provided with projecting part, this projecting part with one end of support bar for being flexibly connected; The other end of support bar is flexibly connected with one end of connecting rod, and the other end of connecting rod is flexibly connected with the end of fixed bar; Connecting rod is knuckle shape, and fixed bar is fixedly installed under body of heater on the large bearing of furnace shell.
In the present invention, described installing rack is fixedly installed on the furnace shell cover plate downside of body of heater by welding manner, and fixed bar is fixedly installed on the large bearing of furnace shell of body of heater by welding manner.
In the present invention, between described dust board and support bar, support bar and connecting rod, connecting rod and fixed bar, all by bearing pin, realize and being flexibly connected.
In the present invention, described dust board is movably arranged on installing rack by the hinge at lateral edges provided thereon place.
In the present invention, the tie point of supposing dust board and installing rack is P point, and the tie point of connecting rod and fixed bar is Q point, and the vertical distance between P point and Q point is A, and the horizontal range between P point and Q point is B; Distance on dust board side between projecting part and P point is M, and the angle between dust board and vertical direction is β; The length of two side rods of knuckle shape connecting rod is respectively X, Y, and the knuckle number of degrees of connecting rod are α; The size of connecting rod, the length L of support bar, apart from M, angle β, distance A, apart between B, there is following relation:
arccos{(A-sinα×Y-cosβ×M)/L}=arcsin{(sinβ×M+B+X-cosα×Y)/L}
In above-mentioned formula, the unit of each length is cm, and the unit of angle is degree.
Compared with prior art, the invention has the beneficial effects as follows:
During turndown of the present invention, under oil cylinder effect, body of heater is pressed axle point and is rotated, and connecting rod departs from grate bearing, and dust board laminating body of heater can effectively stop conduction dust to enter body of heater; While recovering normal condition, under oil cylinder effect, body of heater is pressed axle point counter-rotation, and connecting rod is close to grate bearing, they sup-port dust board, and slot milling, is convenient to regular maintenance and repairs body of heater.

Reference numeral: installing rack 1, dust board 2, support bar 3, connecting rod 4, fixed bar 5, the large bearing 6 of furnace shell.
The specific embodiment
Following embodiment can make the technical staff of this professional skill field more fully understand the present invention, but does not limit the present invention in any way.
The dustproof construction of the medium frequency induction melting furnace in the present embodiment, comprises installing rack 1, dust board 2, support bar 3, connecting rod 4 and fixed bar 5; Wherein, installing rack 1 is fixedly installed on the furnace shell cover plate downside of body of heater by welding manner, and dust board 2 is movably arranged on installing rack 1 by the hinge at lateral edges provided thereon place.At dust board 2, on the side of body of heater, be provided with projecting part, this projecting part is realized and being flexibly connected by bearing pin with one end of support bar 3; The other end of support bar 3 is realized and being flexibly connected by bearing pin with the one end that is the connecting rod 4 of knuckle shape, and the other end of connecting rod 4 is realized and being flexibly connected by bearing pin with the end of fixed bar 5 on the large bearing 6 of the furnace shell that is fixedly installed on body of heater by welding manner.
Suppose that dust board 2 and the tie point of installing rack 1 are P point, connecting rod 4 is Q point with the tie point of fixed bar 5, and the vertical distance between P point and Q point is A, and the horizontal range between P point and Q point is B; Distance on dust board 2 sides between projecting part and P point is M, and the angle between dust board 2 and vertical direction is β; The length of two side rods of knuckle shape connecting rod 4 is respectively X, Y, and the knuckle number of degrees of connecting rod 4 are α; The length L of the size of connecting rod 4, support bar 3, apart from M, angle β, distance A, apart between B, there is following relation:
