Description

Technical Field

[0001] The invention relates to the technical field of energetic material processing, in particular to an automatic cleaning device for a mobile basin-type drying machine. Background Art

[0002] The mobile basin dryer is a double-layer shell continuous dryer that uses hot air to penetrate energetic material particles from top to bottom under slightly negative pressure conditions. During the drying operation, the transmission chain will drive the materials in the drying basin to step into each relatively closed drying area in turn to achieve the drying of the energetic material particles.

[0003] When energetic material particles are dried in a mobile basin dryer, a certain amount of flammable dust and gaseous nitroglycerin will be released. During the drying process, the flammable dust and gaseous nitroglycerin will enter the exhaust pipe along with the drying exhaust gas and adhere to the wall of the pipe. After the drying is completed, the flammable dust will settle on the surface of the drying equipment, and long-term accumulation will form guaranteed deposited dust; gaseous nitroglycerin will condense on the surface of the drying equipment, and long-term accumulation will form highly sensitive nitroglycerin droplets; to ensure safety, the mobile basin dryer (including the exhaust pipe) needs to be cleaned regularly.

[0004] Manual cleaning requires 3-6 hours of rinsing, which results in a huge workload, large water consumption, and inability to clean thoroughly. In addition, the presence of flammable dust and nitroglycerin makes manual cleaning extremely unsafe.

[0057] Furthermore, the alkali solution used for cleaning is a sodium hydroxide solution with a concentration of 3%-6% and a cleaning temperature of 50±5°C.

[0058] Furthermore, the temperature of the hot water for cleaning is 50±5°C.

[0059] The method of using the device includes the following steps:

[0060] Step S1: hot water preparation. After the hot water tank 1 is filled with tap water and reaches the standard liquid level, the tap water is returned to the hot water tank 1 through the high-pressure pump 4 and the steam heat exchanger 5 in sequence. This process is repeated several times until the temperature of the hot water in the hot water tank 1 reaches 45-55°C.

[0061] Step S2: preparing hot alkali solution. Alkali solution tank 2 is sequentially replenished with a certain amount of concentrated alkali solution and softened water in proportion. The agitator of alkali solution tank 2 is started to stir the mixed solution. The concentration of the diluted alkali solution is 3%-6%. The alkali solution is sequentially returned to alkali solution tank 2 through high-pressure pump 4 and steam heat exchanger 5. This is repeated several times until the temperature of the alkali solution in alkali solution tank 2 reaches 45-55°C.

[0062] Step S3: Hot water cleaning. The hot water in the hot water tank 1 enters the automatic cleaning module 11 through the high-pressure pump 4 and the steam heat exchanger 5 in sequence; and the drying equipment is cleaned in the order of the feeding area cleaning nozzle group 1101, the drying area cleaning nozzle group 1102, the warm area cleaning nozzle group 1103, the discharging area cleaning nozzle group 1104, the drying basin cleaning nozzle group 1105, the left air outlet pipe cleaning nozzle group 1106, the right air outlet pipe cleaning nozzle group 1107 and the air outlet main pipe cleaning nozzle group 1108; after the cleaning water is collected in the low-level water tank of the equipment, it returns to the hot water tank 1 through the return pump 12 to realize the reuse of the cleaning water; after repeating the required number of hot water cleanings, the cleaning water is discharged to the sewage pool and all equipment is reset;

[0063] Step S4: Alkali cleaning, the hot alkali liquid in the alkali liquid tank 2 enters the automatic cleaning module 11 through the high-pressure pump 4 and the steam heat exchanger 5 in sequence; and the drying equipment is cleaned in the order of the feeding area cleaning nozzle group 1101, the drying area cleaning nozzle group 1102, the warm area cleaning nozzle group 1103, the discharging area cleaning nozzle group 1104, the drying basin cleaning nozzle group 1105, the left air outlet pipe cleaning nozzle group 1106, the right air outlet pipe cleaning nozzle group 1107 and the air outlet main pipe cleaning nozzle group 1108; after the cleaning alkali liquid is collected in the low-level water tank of the equipment, it returns to the alkali liquid tank 2 through the return pump 12 to achieve the reuse of the cleaning alkali liquid; after repeating the required number of alkali liquid cleanings, the cleaning alkali liquid returns to the alkali liquid tank 2 through the return pump 12, and all equipment is reset;

[0064] Step S5: hot water preparation, execute step 1 again to prepare hot water;

[0065] Step S6: Hot water washing, execute step 3 again for hot water washing. The difference from step 3 is that after the washing water is collected in the low-level water tank of the equipment, the pH of the washing water needs to be tested when it is returned through the return pump 12. The washing water with a pH value that meets the requirements enters the hot water tank 1, and the water that does not meet the requirements is discharged to the sewage tank.

[0066] Furthermore, the method also includes, after cleaning is completed, checking the concentration and turbidity of the alkali solution in the alkali solution tank 2; when the concentration is lower than 2% or the turbidity does not meet the requirements, the alkali solution enters the neutralization tank 3 through the high-pressure pump 4; a certain amount of weak acid is added in proportion, and the agitator of the neutralization tank 3 is started to stir the mixed liquid. When the pH value of the mixed liquid reaches the requirement, the stirring is stopped, and the mixed liquid is discharged into the sewage pool.

[0067] Furthermore, in step S3, step S4 and step S5, during the cleaning process, the steam heat exchanger 5 can reheat the hot water or alkaline solution passing through to ensure that the temperature of the hot water or alkaline solution is 50±5°C.

After the energetic material particles are dried in the pre-powder removal machine, the first elevator, the distribution machine and the multi-temperature zone dryer in sequence, they enter the filling machine through the second elevator to complete the filling and offline. This energetic material particle drying system uses the above-mentioned mobile basin dryer automatic cleaning device before, during and after the drying operation to remove explosive and flammable dust and nitroglycerin during the drying process. Tests and actual use have shown that it can effectively improve the safety of the energetic material particle drying operation.
