Abstract
The utility model discloses a rotary kiln tuyere. An external air duct is spiral, and a special PVC (Polyvinyl Chloride) air pipe is inserted into an inlet of the external air duct, arranged according to the structure of the external air duct and then fixed. The rotary kiln tuyere has the advantages that the service life of the rotary kiln tuyere is the same as that of a rotary kiln lining, no maintenance problem exists, the manufacturing cost of the tuyere is greatly lowered, a rotary kiln is not required to be shut down to maintain the tuyere, and cracks of a casting material of the rotary kiln lining due to temperature variation are decreased, so that the service life of the rotary kiln lining is prolonged.
Description
Technical field the utility model relates to a kind of rotary kiln tuyere.
The present carbon element rotary kiln of background technology tuyere mainly adopts the vertical high tuyere of Kweiyang magnalium designing institute or Shenyang magnalium Design Institute.The tuyere of this kind structure has following some deficiency: 1, because the end of stainless steel airduct is exposed in the high temperature, and its swell increment is greater than the swell increment of pours, and tuyere pours end cracking also comes off, thereby causes tuyere damaged, service life is short.Generally speaking, the tuyere life-span was at 2-4 month; 2, maintenance cost is high.After the tuyere breakage; Must tuyere pours and stainless steel airduct all be changed, about about 8000 yuan of the expense that each tuyere is changed is an example with the rotary kiln of diameter 2.2m, long 45m; The tuyere of changing a kiln needs about 80,000 yuan; Press inner liner of rotary kiln and calculate 2 years service life, rotary kiln will be changed tuyere 5 times at least in an overhaul life, and promptly the tuyere maintenance cost is at least about 400,000 yuan; 3, influence inner liner of rotary kiln service life.The maintenance tuyere causes frequently stopping, opening rotary kiln, causes the inner liner of rotary kiln pours to receive variations in temperature easily and the crack occurs, thereby reduce liner service life.
Summary of the invention is deficiency and the defective part that overcomes prior art, and the utility model provides a kind of rotary kiln tuyere, its long service life, low cost of manufacture.
For the technical scheme that technical problem provided that solves the prior art existence is:
A kind of rotary kiln tuyere, external air channel are spirality, and the special PVC airduct is inserted the external air channel inlet, are provided with by the external air channel structure, and fix.
The rotary kiln tuyere is provided with stainless steel anchoring hook, is welded on the cylinder of rotary kiln.
The advantage of the utility model is: service life is consistent service life with inner liner of rotary kiln, does not have the problem of maintenance; The manufacturing expense of tuyere reduces greatly, and it is original 1/10 that the consumption of pours is about, and do not need stainless steel pipes; Improve rotary kiln service life, consistent service life because of tuyere with the inner liner of rotary kiln life-span, need not to stop kiln maintenance tuyere, reduce the inner liner of rotary kiln pours and received variations in temperature and the crack occurs, thereby improved inner liner of rotary kiln service life.
Description of drawings Fig. 1 is the structural representation of vertical high tuyere;
Fig. 2 is the structural representation of the utility model.
A kind of rotary kiln tuyere of the specific embodiment, external air channel 2 is a spirality, and the special PVC airduct is inserted the external air channel inlet; Arrange by certain direction and angle; And fix, the rotary kiln tuyere is provided with stainless steel anchoring hook, is welded on the cylinder of rotary kiln.The rotary kiln tuyere is by spiral layout.The pours 1,3 identical with the inner liner of rotary kiln material of casting is the stainless steel airduct of vertical high tuyere, and 4 is the pours of vertical high tuyere.
