Technical field
The utility model belongs to metallurgical technology field, is specifically related to the dynamic cooling system of a kind of rotary kiln.
Background technology
In the production of metallurgy industry, chemical industry inorganic salts industry, cement building material industry, all can use rotary kiln.In smelting process; Because the temperature in the cylinder of rotary kiln is up to thousands of degree even higher; And production process need keep continuous state, so although the cylinder of rotary kiln inwall is provided with flame retardant coating, under the effects such as thermal etching that the high-temperature material in cylinder of rotary kiln continues and acid and alkali corrosion; Still can make flame retardant coating and cylinder of rotary kiln constantly encroached on and cause its damage, need correspondingly change after using certain hour.Simultaneously, cause the loss of a large amount of heat energy.Especially the discharging opening place of rotary kiln end is because of thermal etching and the acid and alkali corrosion that directly suffers high-temperature material, so damaged through regular meeting and influence production.Like this, carry out the replacing of flame retardant coating, not only will delay the duration, influence production efficiency, and increase huge production cost; And then say it, if the cylinder of rotary kiln sustain damage, that just will further strengthen production cost, reduce operating efficiency.And the great amount of heat energy loss causes energy waste.
The utility model content
The technical problem that the utility model will solve is: the deficiency that overcomes prior art; Provide a kind of rotary kiln dynamic cooling system, it can effectively reduce the temperature of cylinder of rotary kiln and flame retardant coating, prolongs its service life; Thereby reduced production cost, improved productivity ratio; Improve the heat energy utilization rate.
The utility model solves the technical scheme that its technical problem adopted: the dynamic cooling system of a kind of rotary kiln; Comprise cylinder of rotary kiln, kiln hood and kiln tail; Be provided with flame retardant coating in the said cylinder of rotary kiln, it is characterized in that: between the cylinder of rotary kiln at said kiln hood place and said flame retardant coating, a cooling jacket is set;
Said cooling jacket comprises main cavity, oral siphon, outlet pipe, and said main cavity is arranged at said kiln hood portion; The delivery port of said oral siphon passes to said main cavity through said flame retardant coating, and its water inlet and is gone into the supply mains and is communicated with; The water inlet end of said outlet pipe is arranged in the said main cavity, and its water side is communicated with an outfall sewer.
Preferably, a said end of going into the supply mains is in the place, centre of said cylinder of rotary kiln one end and said oral siphon UNICOM, and the other end is connected with a swivel joint; One end of said outfall sewer is in the place, centre and outlet pipe UNICOM of the cylinder of rotary kiln other end, and the other end is connected with a swivel joint.
Preferably, the said supply mains of going into is arranged at kiln tail or kiln hood; Correspondingly, said outfall sewer is arranged at kiln hood or kiln tail.
Preferably, set firmly prickle, on said prickle, cover flame retardant coating at said kiln hood top.
Preferably, said outlet pipe is more than one.
Preferably, said oral siphon is more than one.
Compared with prior art, the beneficial effect of the utility model is: owing between cylinder of rotary kiln and flame retardant coating, set up cooling jacket, both flame retardant coating was lowered the temperature; Reduce it and change number of times; Reduce cost, made cylinder of rotary kiln avoid corroding again, prolonged its service life; The cooling jacket that use is made up of oral siphon, outlet pipe and main cavity can all be lowered the temperature whole cylinder of rotary kiln and interior flame retardant coating thereof; And as required, also can select to use the cooling jacket of forming by oral siphon, outlet pipe and cooling tubulation; The discharging opening place of rotary kiln end has set up prickle and has added and cover flame retardant coating, has effectively prevented the destruction of high-temperature material to kiln hood.Cooling jacket has absorbed a large amount of heat energy, has effectively improved the heat energy utilization rate.
