Example 2
The invention has the advantages of integral circulation and movable brick kiln operation process.
1) Green brick stacking operation: the continuous brick blank stacking operation is continuously carried out along the circulating kiln path 1 by utilizing the conveyor belt and the stacker crane, and meanwhile, the stacking operation is quickly finished along the circulating kiln path 1 by utilizing the stacker crane to follow the conveying position of the brick blanks along the circulating kiln path 1.
2) And (3) kiln loading operation: through the control equipment in the operation chamber of the walking kiln 2, the sealing baffle device 23 at the front end feed inlet 211 of the kiln body 21 is firstly controlled to lift up to open the feed inlet 211, then the power motor 223 on the walking wheel mechanism 22 is started to operate to drive the walking wheels 222 to move forwards along the kiln walking track 11, so that the distance of two rows of blank stacks walking forwards along the circulating kiln path 1 of the whole kiln body 21 is stopped, the two rows of blank stacks at the front end feed inlet 211 of the kiln body 21 on the circulating kiln path 1 are the kiln body, and finally the sealing baffle device 23 at the front end feed inlet 211 of the kiln body 21 is controlled to fall down to seal the front end feed inlet 211 of the kiln body 21, so that the kiln loading operation of the blank stacks is completed.
3) Ignition operation for the first time: the position of the combustion section 217 in the kiln body 21 is moved to the position of the first row of the stacks, the bricks of the first row of the stacks are combusted by fuel ignition, then the adjacent second row of the stacks are heated by the residual heat of combustion of the first row of the stacks until ignition, and finally the stacks arranged later are sequentially combusted.
4) Firing operation: the blank stack at the combustion section 217 in the kiln body 21 of the walking kiln 2 is a high-temperature combustion operation section, in the combustion process, the control device controls the operation of a smoke exhaust pipe 24 to carry out smoke exhaust from the drying section 215 of the kiln body 21, the high-temperature smoke generated by the combustion of the blank stack at the combustion section 217 passes through the preheating section 216 and the drying section 215 from the combustion section 217 in sequence and is finally exhausted from the kiln top 214 at the front section of the drying section 215, the high-temperature smoke sequentially carries out heating operation on the preheating section 216 and the drying section 215 by using waste heat in the exhaust process, and the temperature is gradually reduced from the rear section of the preheating section 216 to the front section of the drying section 215; the preheating section 216 is close to the combustion section 217, the temperature is high, along with continuous heating of high-temperature flue gas of the combustion section 217, the stack close to the combustion stack is ignited at any time to prepare for combustion, and the temperature of the high-temperature flue gas at the drying section 215 is lower than 100 ℃, so that the stack can be gradually dried in the preparation process, and the green bricks do not need to be dried in the sun to be fired in a kiln like the traditional brick making, thereby improving the production efficiency. When the monitoring equipment shows that the stack at the combustion section 217 reaches the complete combustion degree and the stack at the preheating section 216 close to the combustion section 217 is also ignited, step 2) is executed to move the walking kiln 2 forward, thereby completing the integral movement and kiln loading of the stack in the kiln body 21 on the circulating kiln path 1, the combustion section 217 of the kiln body 21 is moved to the stack ignited by the preheating section 216, the brick blank fired by the combustion section 217 is moved to the cooling section 218, so that the stack on the circulating kiln path 1 is repeatedly operated and continuously loaded from the feed port 211 of the kiln body 21 along with the movement of the kiln body 21, and the stack continuously leaks out on the circulating kiln path 1 from the discharge port 212 at the tail end of the cooling section 218 after being dried, preheated, combusted and cooled in sequence,
continuous firing is realized without interruption.
5) Smoke discharging operation: the walking kiln 2 discharges the smoke dust in the kiln body 21 through the smoke discharge pipe 24 arranged on the kiln top 214 at the front section of the drying section 215 of the kiln body 21, and finally discharges the smoke gas into the desulfurization equipment 4 through the communicated flue 31 for desulfurization, dedusting and innocent treatment and then discharging. In the moving process of the walking kiln 2, the kiln body 21 is fixedly connected with the sliding cover plate 33 on the flue 31 through the flue support 26, and along with the movement of the kiln body 21, the flue support 26 is utilized to drive the sliding cover plate 33 to move synchronously along the flue opening 311 of the flue 31 along with the kiln body 21 on the cover plate sliding track 32 through the sliding frame 331, so that the fixed connection of the exhaust pipe 24 on the kiln body 21 and the exhaust port 312 on the sliding cover plate 33 is ensured, the flue gas is discharged into the flue 31, and the problem of difficulty in discharging the high-temperature flue gas in the moving process of the moving kiln body structure is solved.
6) Waste heat pumping and cooling operation: in the process of firing the kiln body 21, the temperature of the brick pile is extremely high when the brick pile fired from the combustion section 217 of the kiln body 21 is moved to the cooling section 218, the temperature needs to be gradually reduced to normal temperature in the process from the front section of the cooling section 218 to the rear section of the cooling section 218, the natural cooling speed is extremely slow, the too short cooling section 218 can cause the too high temperature of the brick pile after leaking from the kiln body 21, the problem of cracking exists, and the too long cooling section 218 can cause the improvement of the walking power requirement of the kiln body 21. The waste heat pumping-back pipe 25 installed on the kiln top 214 can pump away the high-temperature flue gas at the front section of the cooling section 218 from the brick pile to realize the rapid cooling of the high-temperature brick pile, and simultaneously, the pumped-away high-temperature flue gas is introduced into the drying section 215 of the kiln body 21 from the kiln top 214 at the rear section of the drying section 215 by using the waste heat pumping-back pipe 25, so that not only can the cooling efficiency of the cooling section 218 be improved, but also the waste heat is secondarily used for improving the drying temperature of the drying section 215, and the recycling of the waste heat is realized.
7) Packaging the finished bricks: the brick pillar temperature that leaks from the discharge gate 212 of kiln body 21 after kiln body 21 is fired is the normal atmospheric temperature, under the circumstances that does not receive kiln body 21 and hinder, can directly utilize baling equipment to arrange the packing with the brick pillar, utilizes fork truck whole package to carry away.
