Description
Technical field
The utility model relates to a kind of pressure relief device, is specifically related to a kind of automatic decompression device of automatic ore-smelting furnace.
Background technology
Ore-smelting furnace is the main equipment producing alloy zinc powder, three root graphite electrodes are used to be heat energy by electric energy conversion, the mixture be made up of material containing zinc, coke, lime, quartz is fused in in-furnace slag, and under furnace high-temperature environment, make the ZnO in material containing zinc be reduced by C, CO, generate Zn steam, be condensed into solid successively by movable aditus laryngis, condenser, the first inertial separator, the second inertial separator, bagroom and collect.Ore-smelting furnace adopts two condenser system, ensures that zinc fume is timely, fully cool the alloy zinc powder be condensed into needed for zinc abstraction wet method system.In normal production, because slag slant acidity causes foamy slag, the gas that reaction generates is difficult to discharge, and gathers a large amount of gas and discharges suddenly and cause furnace pressure to increase suddenly; Or due to slag meta-alkalescence, cause slag fusing point too high, solubility weakens, mixture adds and can not be fused to slag in time after in stove and at the long-pending heap of the top of the slag, cave in suddenly when adjusting electric current or buildup is too much, causes furnace pressure to increase suddenly.And ore-smelting furnace production alloy zinc powder requires that normally-pressured neighbor is 50 ~ 400Pa, when pressure is increased to suddenly about 1000Pa, bagroom pressure relief capability is not enough, and pressure is difficult to release in time, pressure is made to be difficult to drop to normal range, thus the normal production of impact; And there is great potential safety hazard, the major accident such as may cause quick-fried punching, rush to summit.
Utility model content
The utility model, can the automatic decompression device of self-relieving automatic ore-smelting furnace when providing a kind of pressure to raise suddenly for the deficiencies in the prior art.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of automatic decompression device of ore-smelting furnace, the condenser comprising ore-smelting furnace and be connected successively with ore-smelting furnace, the first inertial separator, the second inertial separator, bagroom, relief hole is provided with at the top of described condenser, and have counterweight cover at this relief hole upper cover, the upper end thereof of this counterweight cover has montant, the other end of this montant is hinged with connecting rod, and this rod hinge connection is rack-mount.
Further, the stop means limiting counterweight cover shift position is provided with above described counterweight cover.
Further, described stop means comprises the gag lever post be horizontally installed on montant, the symmetrical vertical rod being connected with restriction gag lever post shift position on the condenser at these gag lever post two ends.
Further, the middle part of described connecting rod is hingedly mounted on support, and this connecting rod is provided with configuration block away from one end of montant.
The beneficial effects of the utility model are:
The utility model solves ore-smelting furnace due to foamy slag, buildup and the reason such as to cave in, and the pressure caused raises suddenly cannot the problem of pressure release in time, the generation of the accident such as avoid the quick-fried punching because high pressure causes, rush to summit; After pressure recovery is normal, the utility model can recover automatically, ensures normal, the continuous seepage of equipment; Described counterweight cover moves around the center of circle when counterweight cover having been rushed by connecting rod and support, in order to avoid flown to cause security incident by punching, and being provided with stop means in the upper end of counterweight cover, when preventing counterweight cover from being rushed, upset excessively cannot reset, and resets rapidly after ensureing counterweight cover pressure release; The utility model can regulate the pressure range of pressure release by the weight of balancing weight; The utility model structure is simple, safe and reliable, and the rapid pressure release when pressure raises suddenly, makes pressure drop quickly to normal range, ensures the safety of production process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A portion enlarged view in Fig. 1 of the present utility model.
Fig. 3 is the B-B sectional view in Fig. 2 of the present utility model.
In figure: 1. ore-smelting furnace 2. condenser 3. first inertial separator 4. second inertial separator 5. bagroom 6. counterweight cover 7. montant 8. connecting rod 9. support 10. configuration block 11. gag lever post 12. vertical rod.
Embodiment
As shown in the figure, the condenser 2 that the utility model comprises 3150KVA ore-smelting furnace 1 and is connected successively with ore-smelting furnace 1, first inertial separator 3, second inertial separator 4, bagroom 5, the top of described condenser is provided with a circular relief hole, counterweight cover 6 is had at this relief hole upper cover, the weight of this breeding lid needs the top pressure of pressure release to set according to mineral hot furnace, upper end symmetry centered by the center of circle of counterweight cover of this counterweight cover 6 is hinged with two montants 7, the other end of this montant 7 is hinged with connecting rod 8 respectively, the middle part of this connecting rod 8 is hingedly mounted on support 9 respectively, described two stands 9 is fixedly mounted on the top of condenser side by side, described each connecting rod 8 is separately installed with configuration block 10 away from one end of montant, by regulating the weight of balancing weight, can adjust the top pressure that mineral hot furnace needs pressure release.
In the present embodiment, be provided with above described counterweight cover 6 and limit counterweight cover and to move up the stop means of position.Described stop means comprises the gag lever post 11 be arranged on above counterweight cover 6 on montant, this gag lever post 11 is laterally fixed on two montants 7, these gag lever post 11 two ends condenser on symmetrical being connected with limit gag lever post and to move up the vertical rod 12 of position, vertical rod 12 above gag lever post 11 is provided with boss, by boss, gag lever post is moved below boss, when pressure release is to standard atmosphere pressure, counterweight cover Rapid reset can be made, block relief hole, ensure to arrange normal operation.
Working process of the present utility model is as follows: when pressure exceedes safety range, and gas washes the counterweight cover of condenser overhead open, and by relief hole pressure release, when pressure is let out to safety range, counterweight cover falls automatically, capping relief hole.Rapid pressure release when the utility model can make pressure raise suddenly, makes pressure drop quickly to normal range, ensures that production process is normal, continuous seepage.
