Background technology
The patent of invention that applicant applies in 2012.07.26---vertical lime kiln furnace, the patent No. is 201210261858.4, due to kiln height about 39 meters, volume is comparatively huge, and in calcination process, kiln in-furnace temperature is difficult to control, the easy phenomenon occurring uneven, the inclined burning of calcining, cause causing dross, damage kiln, waste fuel and building stones, maintenance is wasted time and energy and kiln adjustment comparatively difficulty, considerably increases the maintenance cost of kiln; Secondly, for preventing inclined burning, usually needing workman to climb kiln top, carrying out the situation estimating the inner fire bed of kiln, wasting time and energy; Meanwhile, there is larger potential safety hazard.
Summary of the invention
The object of the invention is to overcome above-mentioned defect, a kind of novel kiln with calcining observation device is provided, the calcining of this kiln balances, reduce energy consumption and the calcining situation of kiln can be carried out monitoring in real time and adjust.
The described novel kiln with calcining observation device, comprise kiln, the observer that crown is provided with spy hole and is mated, described observer comprises camera and blind patch, blind patch covers on spy hole, one end of blind patch is hinged on kiln top by steady brace, and the other end of blind patch is provided with return spring, and return spring is fixed on kiln top; Blind patch is provided with stay cord, and stay cord end is placed in bottom kiln.
Further, described stay cord is placed in bottom kiln by pulley, and stay cord end is fixed on the pulley bottom kiln.
Further, the calcining zone bottom of described kiln is provided with waist blast tube.
Further, the chimney place of described kiln is provided with thermopair.
Further, the preheating zone of described kiln, calcining zone and cooling zone place are respectively equipped with thermopair.
Further, the preheating zone of described kiln, calcining zone and cooling zone place uniform 4 thermopairs respectively.
Further, the outside of described camera is provided with sealed shield.
Further, uniform 8 the waist blast tubes in the calcining zone bottom of described kiln.
Compared with prior art, the invention has the beneficial effects as follows:
1, the present invention adopts observer, and passing hole cover plate ensures that the high temperature of kiln does not damage camera, and workman by stay cord adjusting hole cover plate, realizes the observation of camera to kiln inside calcining situation bottom kiln;
2, monitored by the temperature of the thermopair on kiln preheating zone, calcining zone and cooling zone to kiln four orientation, and by unloading grey car accordingly and waist blast tube carries out unloading ash adjustment, to adjust the calcining balance of kiln entirety.
3, the present invention carries out monitoring in real time and adjustment to kiln temperature and overall calcining situation, and avoid the generation of partially burning phenomenon, greatly reduce the energy consumption of kiln, can economize on coal 8 ﹪, and improve the output of 12 ﹪.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1 to Figure 3, the described novel kiln with calcining observation device comprises kiln 1, the top of kiln 1 is provided with spy hole 12 and the observer be mated, described observer comprises camera 10 and blind patch 11, blind patch 11 covers on spy hole 12, one end of blind patch 11 is hinged on kiln 1 top by steady brace 14, and the other end of blind patch 11 is provided with return spring 15, and return spring 15 is fixed on kiln 1 top; Blind patch 11 is provided with stay cord, and stay cord end is placed in bottom kiln 1.
As shown in Figure 2 and Figure 4, stay cord is placed in bottom kiln 1 by pulley first 8, and stay cord end is fixed in the pulley second 13 bottom kiln 1.When needing to observe the fire bed situation of calcining in kiln, workman, by handle rotary pulley second 13, makes stay cord be pulled open by blind patch 11, and camera 10 is observed by the calcining situation in spy hole 12 pairs of kilns, also stay cord is pulled by electric motor, the fire bed situation of charge level in observation kiln.
As shown in Figure 5, the preheating zone of kiln 1, calcining zone and cooling zone place uniform 4 thermopairs respectively.
The present invention when fabrication and installation, uniform 8 the waist blast tubes 4 in calcining zone bottom of kiln 1; Chimney 6 place of kiln 1 is provided with thermopair; The outside of camera 10 is provided with sealed shield 9, each thermopair and observer are connected with the main control room of kiln respectively, can show in main control room kiln four direction calcining situation and by unloading grey car accordingly and waist blast tube carries out unloading ash adjustment, to adjust the calcining balance of kiln entirety, lime enters out ash bucket 7, is finally transported.
When camera 10 observes inclined burning phenomenon, namely the region flame that temperature is high is red, the region that temperature is low is blue, simultaneously in conjunction with the Temperature numerical of each thermopair of preheating zone, calcining zone and cooling zone, when partially burning, will there is larger temperature deviation in the calcining zone thermopair 3 of four direction, during adjustment, in the lower orientation of temperature by unloading grey car 16 and waist blast tube 4 carries out unloading ash, thus make the temperature in this orientation increase, thus reach the calcining balance of kiln entirety.
