h. After the waste packaging barrel 19 finishes paint spraying, the air locking door at the outlet of the paint spraying area 17 is opened, and the waste packaging barrel 19 is conveyed to the discharging area 18 through the conveying chain plate machine 11 for unloading and transferring.

i. In the process d, while the first induced draft fan 23 is started, the second induced draft fan 24 is started, and the exhaust gas in the drying region 14, the inner polishing region 15, the outer polishing region 16 and the paint spraying region 17 is collected to a high-temperature section (such as a decomposing furnace 40 or tertiary air) of the cement kiln through the

second air valves

274, 275, 276 and 277 and the exhaust gas pipeline 26 for incineration disposal.

j. Washing nozzles are arranged in the feeding area 12, the sealed air locking area 13, the drying area 14, the inner polishing area 15, the outer polishing area 16 and the paint spraying area 17, and washing water is sprayed onto an upper side panel of the conveying chain plate machine 11 through a high-pressure water pump 31, a washing water pipe 32 and a first valve 33 in a high-pressure mode, so that scattered waste and waste falling from a scrubbing brush can be washed. Corresponding to these areas, a collecting pool and a liquid outlet are also arranged at the bottom of the conveyor chain plate machine 11, the flushing waste water is collected to the collecting bin 37 through the

corresponding airlock valves

352, 353, 354, 355, 356, 357 and the conveying screw machine 36, the flushing waste liquid in the collecting bin 37 is conveyed to the cement kiln decomposing furnace 40 for high-temperature incineration through the waste liquid conveying pump 38 (for example, a waste liquid conveying plunger pump) and the waste liquid pipeline 39, and an atomizing spray gun 41 can be arranged at the furnace inlet point to ensure that the materials are atomized into the kiln. The collection chamber 37 may be a waste liquid tank, for example, and after a certain amount of waste liquid is collected, the waste liquid is transported and injected into the cement kiln decomposition furnace 40 through the stop valve 371, the waste liquid transportation pump 38, the waste liquid pipeline 39 and the spray gun 41, which are disposed between the collection chamber 37 and the waste liquid transportation pump 38, for harmless incineration disposal.

The invention has the following beneficial effects:

(1) the invention can finish a plurality of procedures of drying, inner polishing, outer polishing, paint spraying and the like of the waste packaging barrel through a platform of the conveying chain plate machine, and can simply and effectively collect and dispose waste residues, waste gases and the like.

(2) The invention fully utilizes the high-temperature hot air of the cement kiln to provide a hot air heat source for the procedures of drying, dehydrating, hardening, pretreating and the like of viscous materials adhered to the waste packaging barrel, does not need to provide an additional heat source, and is clean and environment-friendly.

(3) According to the invention, the subsequent wiping and cleaning can be realized by drying, dehydrating and hardening the viscous material adhered to the waste packaging barrel.

(4) The invention carries out full sealing on a plurality of procedures of drying, inner polishing, outer polishing, paint spraying and the like of the waste packaging barrel, and ensures effective treatment of unorganized emission.

(5) The invention makes full use of the high-temperature alkaline environment of the cement kiln to effectively and safely dispose the collected waste residues.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
