The utility model discloses an airtight lid that airtight electric stove bell top set up, airtight lid encircles and is provided with the sand seal groove week, and the airtight side of covering is provided with the horizontally pull rod, and pull rod one end articulates in the airtight electric stove bell top of airtight lid one side, and airtight caping portion is fixed in at the middle part, and the other end inserts the arcuation guide way that articulates in the airtight airtight electric stove bell top of lid opposite side, the arcuation guide way includes two relative arc boards, forms the pull rod insertion groove of vertical direction. The utility model discloses the grains of sand are blown off by the burner gas in avoiding the sand seal groove, and the elasticity of spring makes an airtight lid high position fall after rise fast, and the accurate set back of airtight lid is guaranteed to the guide way, and is sealed tight, the reliable operation.
Description
Technical field
The utility model belongs to technical field of metallurgy industry, is specifically related to a kind of closed electric furnace explosion-protection equipment.
Background technology
Smelting the electric furnace such as calcium carbide, yellow phosphorus requires as the airtight type of furnace of pressure-fired, so the structure of closed cover and weight can affect its working effect.
Existing closed electric furnace explosion-protection equipment closed cover and explosionproof hole are taper-face contact, and lid periphery adopts sand seal, and furnace pressure size is regulated by the counterweight on closed cover.When closed cover is opened, in sand seal groove, the grains of sand are dispelled by furnace gas; The balance of counterweight makes the closed cover fallen after rise by deadweight fall after rise slowly; Closed cover fall after rise without guiding etc. cause closed cover not set back very soon, poorly sealed.
Summary of the invention
The purpose of this utility model is to provide a kind of closed electric furnace explosion-protection equipment, avoids the grains of sand in sand seal groove to be dispelled by furnace gas, seals more reliable.
The technical scheme that the utility model adopts is:
A kind of closed electric furnace explosion-protection equipment, comprise the closed cover that closed electric furnace bell top is arranged, airtight bezel ring, week is provided with sand seal groove, it is characterized in that:
Be provided with the pull bar of level above closed cover, pull bar one end is articulated with the closed electric furnace bell top of closed cover side, and closed cover top is fixed at middle part, and the other end inserts the arcuation gathering sill being articulated with closed cover opposite side closed electric furnace bell top;
Arcuation gathering sill comprises relative two panels arc plate, forms the pull bar insertion groove of vertical direction.
The arc plate of arcuation gathering sill is provided with gathering sill along arc direction;
Tie rod end is placed between two panels arc plate, is limited in the gathering sill of both sides by guide blot.
Arcuation gathering sill top is fixed with Compress Spring by spring nut and spring spiro rod, and the compression direction of Compress Spring is consistent with the direction of motion of tie rod end.
The hinged end of pull bar is connected to the journal stirrup of closed cover side closed electric furnace bell welded top by bearing pin and split pin.
Be fixed on the otic placode of closed cover top setting by closed cover bolt and closed cover nut in the middle part of pull bar.
The utility model has the following advantages:
The closed electric furnace explosion-protection equipment that the utility model relates to, same employing sand seal, but cancellation counterweight, closed cover weight is by safe pressure requirement design in stove, pin joint and arcuation gathering sill are set respectively in the both sides of closed cover, at gathering sill high-order top assembling Compress Spring, and when making it open by the optimization of lid Inner guide cutter, the outer sand seal cutter dimensional structure of lid, the grains of sand in sand seal groove are avoided to be dispelled by furnace gas, the elastic force of spring makes the high-order falling fast of closed cover, gathering sill ensures that closed cover accurately sets back, and seals tight, reliable operation.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in detail.
A kind of closed electric furnace explosion-protection equipment that the utility model relates to, comprise the closed cover 6 that closed electric furnace bell top is arranged, closed cover 6 ring week is provided with sand seal groove 5.
The pull bar 4 of level is provided with above closed cover 6.Pull bar 4 one end is articulated with the journal stirrup 1 of closed cover 6 side closed electric furnace bell welded top by bearing pin 2 and split pin 3.Be fixed on the otic placode of closed cover 6 top setting by closed cover bolt 7 and closed cover nut 8 in the middle part of pull bar 4.Pull bar 4 other end inserts the arcuation gathering sill 12 being articulated with closed cover 6 opposite side closed electric furnace bell top.
Arcuation gathering sill 12 comprises relative two panels arc plate, forms pull bar 4 insertion groove of vertical direction.The arc plate of arcuation gathering sill 12 is provided with gathering sill along arc direction.Pull bar 4 end is placed between two panels arc plate, is limited in the gathering sill of both sides by guide blot 13.Arcuation gathering sill 12 top is fixed with Compress Spring 11 by spring nut 9 and spring spiro rod 10, and the compression direction of Compress Spring 11 is consistent with the direction of motion of pull bar 4 end.
When furnace pressure is too high, closed cover 6 jack-up, pulled by pull bar 4 and rotate along arcuation gathering sill 12 around bearing pin 2, furnace gas is derived by the inner side diversion cutter of closed cover 6, then the sand seal cutter via closed cover 6 is derived, because inner side diversion cutter height is greater than sand seal cutter, before diversion cutter departs from explosionproof hole, sand seal cutter has departed from sand seal groove, directly air is entered when furnace gas sprays instantaneously, the grains of sand in sand seal groove can be avoided to be dispelled by furnace gas, when Compress Spring 11 encountered by the guide blot (13) connecting pull bar, spring-compressed, seal cover 6 is popped into position by a high position under the effect of Compress Spring 11 elastic force fast by pull bar 4, now sand seal cutter inserts in husky wind groove and realizes sealing.
Content of the present utility model is not limited to cited by embodiment, and the conversion of those of ordinary skill in the art by reading the utility model description to any equivalence that technical solutions of the utility model are taked, is claim of the present utility model and contains.
