In order to solve the above problem, the utility model discloses the technical scheme who adopts is: the emergency cooling device for the suspension cylinder of the Mach-Zehnder kiln comprises a cooling air pipe, wherein one end of the cooling air pipe is arranged in the wall body of the suspension cylinder in a penetrating mode, the other end of the cooling air pipe is connected with an air supply fan through an air supply check valve, a stop valve and a pressure reducing valve are connected between an outlet of the air supply check valve and a compressed air tank in series, and the stop valve is an electric and manual integrated stop valve.
In the above technical solution, a more specific technical solution may also be: and a bypass valve is connected in parallel on a pipeline which is connected in series with the stop valve and the pressure reducing valve.
Further: the stop valve comprises a first stop valve and a second stop valve, and the pressure reducing valve comprises a primary pressure reducing valve and a secondary pressure reducing valve; the first stop valve, the first-stage pressure reducing valve, the second-stage pressure reducing valve and the second stop valve are sequentially connected in series between the compressed air tank and the outlet of the air supply check valve.
Further: the cooling air pipes are provided with two cooling air pipes, one end of each cooling air pipe is arranged in the wall body of the hanging cylinder in a penetrating mode, the other end of each cooling air pipe is connected with an air supply fan through an air supply check valve, a fan selection valve control unit is arranged between outlets of the two air supply check valves, the fan selection valve control unit comprises a first control valve and a second control valve which are connected in series, and a third control valve is connected to a pipeline connecting the first control valve and the second control valve in series in parallel; and a pipeline between the first control valve and the second control valve is connected with a standby fan through a standby stop valve and is connected with an emergency air supply fan through an emergency stop valve.
Since the technical scheme is used, compared with the prior art, the utility model following beneficial effect has:
1. because a stop valve and a pressure reducing valve are connected in series between the outlet of the air supply check valve of the cooling device and the compressed air tank, the stop valve is an electric and manual integrated stop valve; when the Mailz kiln loses power, the stop valve obtains the signal of losing power, opens the stop valve respectively, in time sends into refrigerated compressed gas to the cooling tuber pipe that hangs the cylinder wall body through the relief pressure valve to this cools off hanging the jar, has not only ensured the safe operation of Mailz kiln, has improved work efficiency, has reduced manual operation intensity moreover.
2. Because the bypass valve is connected in parallel on the pipeline connecting the stop valve and the pressure reducing valve in series, the bypass valve can realize that when the stop valve is in failure or the pressure reducing valve is blocked by foreign matters, compressed air cannot pass through the pipeline where the stop valve is located, the bypass valve can be manually opened, and the compressed air can be well cooled for the cylinder body of the suspension cylinder through the bypass pipeline.
3. The stop valve comprises a first stop valve and a second stop valve, and the pressure reducing valve comprises a primary pressure reducing valve and a secondary pressure reducing valve; the first stop valve, the first-stage pressure reducing valve, the second-stage pressure reducing valve and the second stop valve are sequentially connected in series between the compressed air tank and the outlet of the air supply check valve; the first-stage pressure reducing valve and the second-stage pressure reducing valve can play a role in stably reducing pressure, and the first stop valve and the second stop valve are used for closing a passage of compressed gas to the suspension cylinder body in a normal production state, namely, the suspension cylinder body of the Maerz kiln is respectively cooled by the suspension cylinder air supply fan. Under the power-off state, the system opens the electric stop valve through control, and compressed air is well cooled for the suspension cylinder system through the stop valve and the pressure reducing valve pipeline. And the stop valve can effectively cut off a compressed air system and a cooling air pipeline of the suspension cylinder, and is favorable for the maintenance of the daily pressure reducing valve.
