Description

Technical Field

[0001] The utility model relates to the technical field of vacuum conveyors, in particular to a plastic particle vacuum conveying device which is easy to install. Background Art

[0002] The structure of the vacuum conveyor mainly includes a vacuum pump, a pipeline system, a filter, a control system, etc. The working principle of the vacuum conveyor mainly depends on the negative pressure generated by the vacuum generator, that is, a high vacuum is generated through a vacuum pump or compressed air through a vacuum generator, forming a vacuum environment in which the pressure in the conveying system is lower than the atmospheric pressure. This negative pressure effect allows the material to be sucked into the pipeline and transported along the pipeline to the destination. During the transportation process, the material and the air are completely separated by the filter to ensure that the material will not enter the vacuum pump and dissipate into the atmosphere. When the material fills the silo, the controller will automatically cut off the gas source, the vacuum generator stops working, and the silo door automatically opens, and the material falls into the hopper of the equipment. However, there are still certain problems when using the existing plastic granule vacuum conveying device:

[0003] For example, the vacuum conveyor with announcement number CN215046954U has the following technical scheme: it includes a vacuum conveying bin body, a vacuum conveying upper cone is installed on the top of the vacuum conveying bin body through a connecting part, the inner diameter of the top of the vacuum conveying upper cone gradually decreases in the vertical upward direction, a negative pressure interface is arranged at the center of the top of the vacuum conveying upper cone, a feed port is arranged on the outer wall of one side of the vacuum conveying bin body, a discharge port is arranged at the bottom of the vacuum conveying bin body, a discharge valve for controlling the on-off of the bottom of the vacuum conveying bin body is installed on the side wall at the bottom end of the vacuum conveying bin body, and a self-cleaning air bag is installed on one side of the top of the vacuum conveying upper cone through a mounting frame. The utility model can output airflow to the filter element in the vacuum conveying bin body through the self-cleaning air bag and the connecting pipe during the material conveying process, thereby blowing off the material attached to the filter element, but the existing vacuum conveyor is complicated to operate during the installation process, and workers need to work together to lift the bin to the top of the receiving box in advance, and it is troublesome to fix the pipeline tightly to prevent leakage when connecting the pipeline.

[0004] In view of this, we conducted in-depth research on the above issues, which led to the present case.
