Preferably, said cooling jacket comprises cooling tubulation, oral siphon and outlet pipe, and the delivery port that the water inlet end of said oral siphon and is gone into the supply mains is connected, and its water side is communicated with said cooling tubulation; The water inlet end of said outlet pipe is arranged in the said cooling tubulation, and its water side is communicated with an outfall sewer.
Preferably, the said supply mains's of going into water inlet connects a swivel joint, and its delivery port is arranged at the centre of cylinder of rotary kiln;
One end of said outfall sewer is in cylinder of rotary kiln centre and outlet pipe UNICOM, and the other end passes to cylinder of rotary kiln, is connected with a swivel joint.
Preferably, the said supply mains of going into is arranged at the kiln tail of said rotary kiln; Correspondingly, said outfall sewer is arranged at the kiln hood of said rotary kiln.
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.
Preferably, said cooling tubulation is along the axially-aligned of cylinder of rotary kiln, and is more than two.
Compared with prior art, the invention has the beneficial effects as follows:, both flame retardant coating was lowered the temperature owing between cylinder of rotary kiln and flame retardant coating, set up cooling jacket; 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.
