The invention has the characteristics of high heating efficiency, high heating speed, low investment, quick effect taking and the like, and can quickly melt the crystallized material. Meanwhile, the quick dredging and heating device does not leave any residue in the practical application process, fully utilizes the raw material, and increases the application rate of the raw material, thereby lowering the product cost and enhancing the economic benefit of the delivery product.
Description
(1), technical field:
The present invention relates to a kind of heating unit, be specifically related to a kind of ammonium nitrate or ammonium nitrate and oxidizer salt aqueous solution storage tank blowing is dredged heating unit fast.
(2), background technology:
In the explosive production process, usually will be with the solution heating of ammonium nitrate or ammonium nitrate and oxidizer salt, it is standby to be incubated certain temperature, in insulating process, because the very easily crystallization of the aqueous solution of ammonium nitrate or ammonium nitrate and oxidizer salt, often in the blowing process, stopping up appears in the discharge port pipeline of storage tank and baiting valve, though storage tank is incubated, and employing insulation baiting valve, but be very easy to produce crystal apart from the storage tank end between storage tank and baiting valve, this segment pipe is because of easily producing crystallization and occurring stopping up in the production process.General in the market many employing installation chucks are incubated, or directly lead to the crystal position from the discharge port pipeline with steam, and this crystal that prevents produces or eliminate crystal, and the existence personnel that cause scald the thermal insulation layer with easy injury tank body; Take the chuck heating also to be difficult to melt the crystal of discharge port duct bottom in addition, even cause local superheating easily, produce unsafe factor, bring great inconvenience to production.Particularly using liquid ammonium nitrate to prepare emulsion explosive, during liquid ammonium nitrate storage tank blowing, the discharge port pipeline can be frequently blocked, has a strong impact on ordinary production.
(3), summary of the invention:
The object of the present invention is to provide that a kind of heating efficiency height, speed are fast, melting crystal material, safety coefficient height, ammonium nitrate easy to use or ammonium nitrate and oxidizer salt aqueous solution storage tank blowing are dredged heating unit fast fast.
For achieving the above object, technical scheme of the present invention comprises " U " type heating tube and sleeve pipe, described " U " type heating tube is arranged in the sleeve pipe, and the import of " U " type heating tube is all stretched out described telescopic sidewall with exit end and fixedlyed connected with this sleeve pipe, and the sleeve pipe two ends are respectively arranged with flange.
In the technique scheme, feed steam or hot water in described " U " type heating tube.
In technique scheme, telescopic one end is connected with storage tank discharge port pipeline by flange, and the other end is connected with baiting valve by flange, forms a complete blowing passage, adopts flange to connect its good sealing effect; " U " type heating tube is positioned in the storage tank discharge port pipeline, and there are steam or hot water to pass through in " U " type heating tube, be convenient on the one hand to keep the temperature in the storage tank discharge port pipeline, thereby prevent that effectively ammonium nitrate or ammonium nitrate and the oxidizer salt aqueous solution storage tank crystalline in the blowing process from producing, and improves raw-material rate of utilization; Help protecting the thermal insulation layer of storage tank discharge port pipeline and storage tank contact position on the other hand, reduce the production line energy consumption greatly, improve cleaner production level and batching speed, increase work efficiency.
(4), description of drawings:
Fig. 1 is that a kind of ammonium nitrate solution storage tank of the present invention blowing is dredged heating unit user mode synoptic diagram fast;
Fig. 2 is that a kind of ammonium nitrate solution storage tank of the present invention blowing is dredged the heating unit structural representation fast.
(5), embodiment:
Below in conjunction with accompanying drawing a kind of ammonium nitrate solution storage tank of the present invention blowing being dredged heating unit fast is described further;
By Fig. 1, Fig. 2 as seen, the present invention includes " U " type heating tube 1 and sleeve pipe 2, described " U " type heating tube 1 is arranged in the sleeve pipe 2, and the import 3 of " U " type heating tube 1 is all stretched out the sidewall of described sleeve pipe 2 with outlet 4 ends and fixedlyed connected with this sleeve pipe 2, and sleeve pipe 2 two ends are respectively arranged with flange 5,6.
In the such scheme, feed steam or hot water in described " U " type heating tube 1.
When the present invention works, sleeve pipe 2 one ends are connected with basin discharge port pipeline 10 by flange 5,5 ', the other end is connected with baiting valve 7 by flange 6,6 ', make " U " type heating tube 1 part put into basin discharge port pipeline 10, another part forms a complete blowing passage in sleeve pipe 2.The import 3 of " U " type heating tube 1 is all stretched out the sidewall of sleeve pipe 2 with outlet 4 ends and is fixedlyed connected with this sleeve pipe 2, steam or hot water enter by import 3, according to temperature required, adopt vapor volume or hot water amount in thermal insulation valve adjusting " U " type heating tube 1, keep the temperature in the basin discharge port pipeline 10, and then flow out by outlet 4.Adopt this device, connect its good sealing effect by flange; 1 li of heating tube is because of having steam or hot water to pass through, and temperature is all permanent, thereby guarantees the temperature in the basin discharge port pipeline 10.When baiting valve 7 is opened, can realize quick blowing, also can effectively prevent ammonium nitrate or ammonium nitrate and the crystallization of oxidizer salt aqueous solution obstruction basin discharge port pipeline 10, realize ordinary production, effectively save man-hour, enhance productivity, reduce product cost.
In the present embodiment, use heating tube 1 heating, storage tank discharge port pipeline 10 is not easy to be damaged with the thermal insulation layer 8 of storage tank 9 contact positions, reduces the production line energy consumption greatly, improves cleaner production level and batching speed, increases work efficiency.
For example ship 30 tons of ammonium nitrate solutions from ammonium nitrate factory, 135 ℃ of temperature are stored in the storage tank 9, are used to produce emulsion explosive.In the production process, feeding vapor pressure is 1 kg/cm, uses heating tube 1 heating, produces and consumes 15 tons of ammonium nitrate solutions, line clogging do not occur.One day at interval, storage tank 9 temperature are reduced to 125 ℃, produce again and just have to heat, when storage tank 9 temperature reach 135 ℃, carry out ordinary production solution, occur in the storage tank discharge port pipeline 10 stopping up, put the raw material of the galactopoiesis explosive of not being born, only need feed steam or hot water to heating tube 1 this moment to the import 3 of sleeve pipe 2, heated 10 minutes, blocked storage tank discharge port pipeline 10 is dredged at once, returns to normal production.Thereby realize saving man-hour, enhance productivity.
In the present embodiment, described " U " type heating tube 1 and sleeve pipe 2 all adopt stainless material to make, has erosion resistance, the intensity height, any surface finish, therefore the heat insulating coefficient height uses in hot-water system and has effectively reduced heat energy loss, secondly it be again 100% can reclaiming material, can not cause environmental pollution.
" U " type heating tube 1 among the present invention is owing to be embedded in the solution, the heating efficiency height, and speed is fast, the material of melting crystal fast, less investment, instant effect.Simultaneously, do not stay least bit residue in the process that puts into operation, can fully use raw material, improve the rate of utilization of raw material, thereby reduce the production line energy consumption greatly, improve the economic benefit of manufacturer.
The ammonium nitrate material that the present invention also can be applied to ammonium nitrate production factory stores and transportation art.
