Detailed Description
Referring to fig. 1 to 4, the vacuum drying recovery system of the present invention comprises a vacuum drying oven 1, a first heat exchanger 2, a liquid collecting tank 3 and a vacuumizing device 5 which are sequentially connected through pipelines; the first heat exchanger 2 is arranged above the liquid collecting tank 3, the vacuum drying oven 1 comprises an oven body, a heating device is arranged in the oven body, and a plurality of placing layers 11 are arranged from top to bottom; each tray group 6 comprises two rows of square trays 61, each tray 61 is provided with a penetrating and lifting structure, penetrating and lifting structures on the trays 61 in the same row are all on the same straight line, and the penetrating and lifting structures are parallel to the straight line of the penetrating and lifting structures on the trays 61 in the other row in the same tray group 6. The working flow and principle of the invention are as follows: firstly, filling a mixture of oil sludge, paint slag and the like into a tray 61, and then arranging the tray 61 into a tray group 6; then, two forks of a forklift respectively penetrate through all the penetrating lifting structures on different rows of trays 61 in the tray group 6, and then all the trays 61 in the tray group 6 are lifted and conveyed into the box body of the vacuum drying box 1 through the forklift at the same time and are stacked in the placement layer 11; after the tray group 6 stacks all the placement layers 11 in the vacuum drying box 1, starting the heating device, the first heat exchanger 2 and the vacuumizing device 5, so that the vacuum drying of the mixture such as the oil sludge or the paint slag is realized in the environment that the high-temperature vacuum is generated in the box body of the vacuum drying box 1, the liquid in the mixture is changed into steam, the steam enters the first heat exchanger 2 to realize condensation, and liquid drops formed by the condensation flow into the liquid collecting tank 3 through a pipeline to realize recycling; after the vacuum drying is finished, solid matters in the mixture such as oil sludge or paint slag are dried in the tray 61, then the box body of the vacuum drying box 1 is opened, and the tray 61 is carried out of the box body by taking the tray group 6 as a unit through a forklift; the trays 61 are then taken out of the tray group 6, and the dry and solid materials in the trays 61 are directly poured out and recovered by means of the back-off tray 61 or the like, or the solid materials adhered to the inner wall of the tray 61 can be directly scraped off by a tool. The present invention adopts a form that a plurality of trays 61 are formed into a tray set 6, not a form that a single tray 61 with a size enough to match the whole tray set 6 is adopted, because when the tray 61 is large and the tray 61 is filled with a mixture of oil sludge, paint slag, etc., the middle part of the tray 61 is raised downwards due to gravity and even breaks, thus the lifting and transportation of the tray 61 by a forklift are affected, and after the vacuum drying is finished, the dry and solid matters in the tray 61 are difficult to pour out by manpower. Therefore, the invention can effectively realize separation and utilization of the mixture such as the oil sludge or the paint slag, and can also effectively remove the dried block obtained after the vacuum drying, thereby avoiding the problem that the dried block is difficult to clean because the dried block is directly adhered inside the vacuum drying box 1, avoiding the problem that the vacuum drying box 1 is damaged because the dried solid block is cleaned, being beneficial to reducing the maintenance cost and prolonging the service life of the whole vacuum drying recovery system; meanwhile, the pallet group 6 and the alternate lifting structure are arranged, so that the forklift can be conveniently adopted for lifting and transporting, the carrying time is saved, and the production efficiency is improved.
