Abstract

The invention discloses a vacuum exhaust device for a discharge barrel of a waste plastic recycling and granulating line. The device comprises an exhaust cover arranged on the discharge barrel; the exhaust cover comprises an exhaust cover body and a cover plate; the exhaust cover body comprises a cavity and a plate edge on the upper edge of the cavity and capable of cooperating with the cover plate; the cavity communicates with an inner cavity of the discharge barrel; the cover plate is fixed on the plate edge; an air channel is formed between the cover plate and the plate edge; the bottom of the plate edge or the top of the cover plate is provided with a vacuumizing port; and one end of the vacuumizing port is connected with the air channel, and the other end of the vacuumizing port is connected with a vacuumizing device. During working, the materials pass through the cavity and are blocked by the cover plate; the air channel facilitates air flow, and the vacuumizing port is located at the bottom of the plate edge or the top of the cover plate, then during vacuumizing, the vacuumizing port will not be blocked by materials, so as to realize more smooth air flow and high pumping speed, and expand production capacity.

Description

technical field [0001] The invention relates to a vacuum exhaust device for a discharge cylinder of a waste plastic film recovery and granulation line. Background technique [0002] The vacuum port of the original vacuum exhaust device is inside the exhaust cover. When pumping air, due to the small internal space of the exhaust cover and the small air flow, the materials in the exhaust cover are often drawn out with the water vapor, and the pumped The blockage of the vacuum port will easily damage the exhaust cover on the one hand, and affect the normal vacuum exhaust work on the other hand. [0003] In order to make up for the above shortcomings, our company has improved the vacuum exhaust device to avoid the material in the exhaust cover from blocking the vacuum port. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a vacuum exhaust device for the discharge cylinder of waste plastic film recycling and granulati...
