Abstract
The utility model discloses a device for preventing blockage of expanded materials in an expanding and crystallizing machine. The device comprises a jet pipeline (1) belonging to a unique channel for jetting the materials in the expanding and crystallizing machine (3), wherein jet holes (2) are uniformly distributed in the jet hole end of the bottom of the jet pipeline (1); a planar scraping plate (4) is arranged in the expanding and crystallizing machine (3); and a flat helical conveying channel (6) is arranged at an outlet of the expanding and crystallizing machine (3). The device has the advantages of being capable of effectively preventing blockage of the expanded materials in the expanding and crystallizing machine to eliminate the potential safety hazard in production, being simple in structure, convenient to manufacture, safe and reliable to use and the like.
Description
Technical field
the utility model relates to a kind of device that prevents expanded feed blocking in expanded crystallizer, belongs to expanded crystallizer technical field for explosive production.
Background technology
in bulking ammonium nitrate explosive production process, it is the unique passage entering in expanded crystallizer that water oil phase mixing solutions sprays pipeline, it is the circular hole that is less than 4mm that the end face of pipeline has been covered with diameter, circular hole is spouting by the form of spray by water oil phase mixing solutions, the solution of ejection under swelling agent and condition of negative pressure, expanded one-tenth porous, loose bulking ammonium nitrate explosive.Because of shower nozzle Circularhole diameter less than normal, ejection high-density spray, cause expanded surplus, expanded explosive density is less than normal, and expanded explosive is too fluffy, thereby can not meet Technology requirement, cause blanking not smooth simultaneously, putty phenomenon is serious, affects serialization and produces, and also has potential safety hazard because pipeline pressure is bigger than normal.
the effect of expanded crystallizer middle scraper is to enter after expanded good material is scraped to crystallizer
flat spin, arc design that what scraper plate was taked is, the concave regions that made scraper plate intermediate formation, causes in expanded crystallizer expanded solid accumulation too much, scrapes medicine and does not freely easily cause medicinal powder to put up a bridge, and is unfavorable for prescribe medicine, has affected the discharging of expanded crystallizer.Because accumulating easily of explosive causes in crystallizer and stop up; in order to guarantee normal production; usually need to shut down the expanded material stopping up in expanded crystallizer is cleared up; expanded crystallizer is as the key equipment of explosive production; one shuts down the stoppage in transit row that will cause whole production line, has had a strong impact on the output of producing.After expanded crystallizer obstruction, cleaning difficulty is large in addition, usually needs site work personnel to probe in crystallizer and clears up, and has potential safety hazard.
Summary of the invention
the purpose of this utility model is, a kind of device that prevents expanded feed blocking in expanded crystallizer is provided, with solve expanded explosive produce in because expanded crystallizer stops up the problem that causes production line normally not move, eliminate the potential safety hazard of existence in producing.
the utility model is to form like this: a kind of device that prevents expanded feed blocking in expanded crystallizer of the present utility model is, this device comprises the injection pipe that is subordinate to expanded crystallizer material and sprays unique passage, jet orifice end in injection pipe bottom is evenly equipped with jet hole, in expanded crystallizer, be provided with plane scraper plate, be provided with flat spin transfer passage in the exit of expanded crystallizer.
the aperture of above-mentioned jet hole is 4mm～7mm.
above-mentioned plane scraper plate is vertical with the crystallizer inner bottom surface of expanded crystallizer.
owing to having adopted technique scheme, the nozzle inside diameter on water oil-phase solution injection pipe is designed to 4mm～7mm by the utility model, thereby increase spray mixture particle, the expanded material density ejecting can be controlled at again in the scope of Technology requirement satisfied preventing in obstruction from requiring; The utility model is changed into existing scraper plate the plate of plane formula and blade angle is strengthened by arc simultaneously, make the plane of plane scraper plate perpendicular to expanded crystallizer inner bottom surface, thereby effectively avoid the generation of expanded explosive medicinal powder bridging phenomenon, and can totally smoothly expanded explosive have been scraped in flat spin transfer passage.Therefore, the utility model compared with prior art, can effectively prevent that in expanded crystallizer, expanded feed blocking is eliminated the potential safety hazard existing in production thereby the utility model not only has advantages of, but also there is the advantages such as simple in structure, easy to make, safe and reliable.
Accompanying drawing explanation
fig. 1 is the structural representation of the utility model device;
fig. 2 is the structural representation of the uniform jet hole of the utility model device injection pipe jet orifice end.
being labeled as in accompanying drawing: 1-injection pipe, 2-jet hole, the expanded crystallizer of 3-, 4-plane scraper plate, 5-crystallizer inner bottom surface, 6-flat spin transfer passage.
Embodiment
below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to any restriction of the present utility model.
embodiment of the present utility model: the utility model is a kind ofly to prevent that the method for expanded feed blocking in expanded crystallizer is constructed according to following, the method can be implemented on existing expanded crystallizer, the method is that the aperture of the injection pipe jet hole by expanding existing expanded crystallizer reduces higher expanded surplus and the spray tube pressure of causing of spraying of material density and increases the problem of stopping up, make water oil phase mixing solutions from jet hole sprays suitable spray, form density and meet the expanded material that Technology requires, thereby both solved the higher problem of injection pipe pressure, can meet again bulking process technical requirements, its from jet hole sprays suitable spray, form density meet Technology require expanded material scrape by plane scraper plate in the flat spin transfer passage of expanded crystallizer, by existing circular arc scraper plate being changed over to the plane scraper plate of planar shaped, more can in time expanded good material be scraped to crystallizer smoothly and enter flat spin transfer passage, thereby can effectively avoid the expanded material scraping because of the generation having some setbacks, material bridging phenomenon appears in overheap.Described expanded material is the expanded explosive in traditional mode of production.
the of the present utility model a kind of structural representation that prevents the device of expanded feed blocking in expanded crystallizer building according to aforesaid method as depicted in figs. 1 and 2, this device comprises the existing injection pipe 1 that is subordinate to expanded crystallizer 3 materials and sprays unique passage, when making, jet orifice end in injection pipe 1 bottom is produced jet hole 2 by equal mode for cloth, and the aperture of jet hole 2 is controlled in the scope of 4mm～7mm; Then in expanded crystallizer 3, install the plane scraper plate 4 of planar shaped, and make the scraper plane of this plane scraper plate 4 and the crystallizer inner bottom surface 5 of expanded crystallizer 3 vertical; A flat spin transfer passage 6 is simultaneously set in the exit of expanded crystallizer 3.
the flat spin transfer passage 6 adopting can directly adopt helical feed lane device finished product of the prior art.
