The invention relates to a vacuum evaporation system capable of controlling evaporating airflow distribution and components. The system comprises an evaporation gun, a high-temperature evaporation crucible and a storage tank filled with an evaporating material, wherein a nozzle with an upper conical surface and a lower conical surface is formed on the evaporation gun, and a movable airflow guidance plug is arranged inside the nozzle; a substrate to be evaporated is opposite to the front of the nozzle; the evaporation gun is connected with the high-temperature evaporation crucible which is provided with a cross baffle through a heat pipeline or a surge flask, and the other side of the crucible is connected with the storage tank through a pipeline which is provided with a feed valve; heating coils are arranged on the evaporation gun, the heat pipeline, the high-temperature evaporation crucible and the outer wall of the pipeline, and a heat coil is arranged on the outer wall of the storage tank as well; the evaporating material in the storage tank is delivered into the high-temperature evaporation crucible through the feed valve and the pipeline, so that the evaporating material to be evaporated is immediately turned to be vapor delivered to the evaporating gun; and the volume and the direction of the vapor can be controlled by changing the relative position of the airflow guidance plug and the nozzle, and the vapor is evaporated to the substrate to form an evaporating film, which is uniform and has set area and multiple components. The vacuum evaporation system has simple structure, can improve the utilization rate of the organic evaporating material, and can improve the production efficiency.

The invention discloses a sludge drying device, and belongs to the technical field of sludge drying. The sludge drying device comprises a kneading roller (10) mounted above a drying heating tray (3) and connected with a sludge conveyor (1), wherein the drying heating tray is encircled by a chain (8); the two ends of the chain are driven by drive sprockets (5); a gear rack (9) is arranged between the upper part of the drying heating tray and the chain; harrow cutters (4) are uniformly distributed on the chain. The sludge drying device is high in porosity, large in superficial area of sludge particles, light in ton proportion, strong in breathability, high in humidity difference value, powerful in drying power, and quick in rate of evaporation; the sludge material is longitudinally shifted and conveyed, and the cutting force breaks the adhesion of the sludge, so that the sludge cannot generate a snowball effect; the sludge drying device is simpler by modularization, convenient to transport, low in failure rate, and convenient to produce and maintain, and has the advantage that phenomena such as dust caused by falling are avoided; in the drying process, the back mixing is not required, the exhausted air quantity is low, and the follow-up handling expense is low.

The invention belongs to the technical field of Parylene F-type vapor deposition, and in particular relates to a Parylene F-type vapor deposition method; by optimizing and improving the evaporation process and the cracking process, the Parylene F-type raw material which is difficult to deposit can also obtain faster evaporation The film composition has excellent purity performance, and no changes have been made to the common Parylene vapor deposition equipment in China, which greatly improves the processing efficiency under the premise of ensuring the film performance. At the same time, due to the stable evaporation rate, the thickness of the final film layer can be controlled by controlling the process time, which reduces the difficulty of film thickness control and makes the reaction more controllable.
