Abstract
The utility model relates to a safety blank cover device of a steel slag hot disintegrating pond, which comprises a cover body, a pressure-relief protection device, a cooling water spray device and a water seal tank between the cover body and the hot disintegrating pond, and is characterized by further comprising an explosion protection device connected with the cover body and the water seal tank, so as to avoid the displacement of the safety blank cover device during the explosion. As the explosion protection device, as the last safety guarantee, is arranged on the safety blank cover device, when the steam pressure in the hot disintegrating pond is excessively high or the pressure-relief protection device on the safety blank cover device fails to work, the explosion protection device can still work, and the safety index during the hot disintegration treatment of the steel slag hot disintegrating pond is further improved.
Description
Technical field
The present invention relates to a kind of slag processing equipment, be specifically related to the safe stifle device in a kind of steel slag hot disintegrating pond.
Background technology
The Technology that steel slag hot disintegrating is processed is ripe, principal feature is high-temperature liquid state slag (1200 ℃～1600 ℃ of temperature) from the slag ladle of packing into after steel melting furnace is discharged, directly pour hot disintegrating device into through slag ladle, then it is vexed to add a cover water spray heat, technical process is simple, has after the processing that the slag efflorescence is effective, metal recovery rate is than advantages of higher.Yet molten steel slag can produce a large amount of steam and unknown chemical gas etc. in vexedization of the water filling process in vexed pond, if misoperation can cause superpressure and blasts, stifle is blown up to cause to produce and arranged and personal injury when serious.
At present the safety guard of stifle device generally adopts is that to utilize the lid own wt to add water seal airtight; be provided with two decompression protection devices on lid top; when vapor pressure is too high in the vexed pond; wash the rupture disk pressure release on the lid open; prevent that lid from blowing up, but in the actual use procedure, lid still occurs frequently blow up phenomenon; the essential safety performance that improves cold stoking occurs for stopping this phenomenon.The steel slag hot disintegrating pond stifle device (referring to Fig. 1, Fig. 2 and Fig. 3) of prior art; comprise the compositions such as lid, decompression protection device, sprinkling device for cooling water and water sealed tank; measures for the prevention of explosion wherein mainly is decompression protection device; the pre-main means of blast protection in the steel slag hot disintegrating process; see according to service condition in recent years; brisance is very big during because of vexed slag, although the decompression protection device on the stifle device has been brought into play effect, effect is still undesirable.
Chinese patent ZL201020521083.6 discloses a kind of fused pyrolytic steel slag exhaust device with blank cap, by at hot stifle device gas barrier being set, with molten steel slag issuable unknown chemical gas discharge in vexedization of the water filling process in vexed pond, reduce the explosion potential because of the unknown chemical γ-ray emission.
Chinese patent ZL200920260266.4 provides a kind of steel slag hot disintegrating lid arrangement, by offering pressure relief vent at its lid and in the pressure relief vent sealing mode of unloading press mold being installed removably, can artificially accurately set it and unload pressure pressure, reach the purpose of the safety that improves hot vexed processing.
Above-mentioned patented technology all reaches the security purpose that improves the steel slag hot disintegrating processing by the mode of pressure release; namely relate to decompression protection device; but when if vapor pressure is too high in the hot vexed pond; rapidly pressure release and blasting of moment; still the danger that exists lid to be blown up threatens for the safety of the person and environment.Therefore in a single day, blast in the steel slag hot disintegrating treating processes, how this realizes last protection, and the security that how to guarantee the stifle device in steel slag hot disintegrating pond is the problem that needs solution.
The utility model content
The utility model provides the safe stifle device in a kind of steel slag hot disintegrating pond for the limited defective of safety control performance of the stifle device in steel slag hot disintegrating pond in the above-mentioned prior art.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The safe stifle device in a kind of steel slag hot disintegrating pond; comprise lid, decompression protection device, sprinkling device for cooling water and water sealed tank; described water sealed tank is arranged between described lid and the hot vexed pond; it is characterized in that; also comprise the explosion protection device; described explosion protection device comprises several the first protection hooks, and described the first protection hook one end is fixed in described lid, and the other end is buckled in described water sealed tank.
Further, described the first protection hook is the hook that is rigidly connected.
Further, described explosion protection device also comprises several the second protection hooks, and described the second protection hook one end is fixed in described water sealed tank, and the other end is buckled in described lid.
Further again, described the second protection hook is for flexibly connecting hook.
The beneficial effects of the utility model are:
Blast when vapor pressure is too high in the vexed pond in vexed slag process in heat vexed pond, because the effect of explosion protection device guarantees that the explosion time lid is not blown up, guaranteed the integrity of equipment, ensured safety and the personnel safety of Working environment; Safe stifle device of the present utility model; because it is provided with the explosion protection device as last one safety control of stifle device at the stifle device; even the decompression protection device on the stifle device lost efficacy; still have the explosion protection device to play a role, improved the safety index when steel slag hot disintegrating pond heat is vexed to be processed.
