Description

Technical Field

[0001] The utility model relates to the technical field of impurity removal of plastic master batch raw materials, in particular to an impurity removal device for plastic master batch raw materials. Background Art

[0002] Plastic masterbatch is a kind of plastic processing aid, which is composed of excess chemical additives, carrier resins and dispersants. Masterbatch is an aggregate obtained by uniformly loading an excess amount of pigments (dyes) in the resin. Masterbatch refers to the granular material obtained by mixing and kneading various required additives, fillers and a small amount of carrier resin in the process of plastic processing and molding for the convenience of operation, and then through the process of metering, mixing, melting, extrusion, pelletizing and other processing by extruders and other equipment. It is called masterbatch.

[0003] At present, the raw materials for producing plastic masterbatch are directly put into the internal mixer without screening. The raw materials are mixed with impurities and dust, which leads to the performance of the produced plastic masterbatch being reduced, the quality failing to meet the requirements, and the qualified rate being low, which brings certain economic losses to the factory. At the same time, the raw materials are manually screened before production, which is labor-intensive, consumes more manpower and time, and increases labor costs.

[0004] Therefore, we propose a plastic masterbatch raw material impurity removal device. Utility Model Content

[0005] The main purpose of the utility model is to provide a plastic masterbatch raw material impurity removal device. Through the arrangement of the dividing rod, not only can the plastic masterbatch raw material be dispersed as it is put into the material inlet and pass through the dividing port to fall onto the screening mesh plate, but also the falling time of the plastic masterbatch raw material can be prolonged, so that the dust in the plastic masterbatch raw material can be sucked away by the exhaust fan during the falling process of the dividing rod. At the same time, the arrangement of multiple dividing ports can also prevent all the plastic masterbatch raw materials from accumulating in the same place of the screening mesh plate, avoiding inaccurate screening, and the inclined screening mesh plate can allow the impurities inside the plastic masterbatch raw material to pass through the screening mesh plate and fall into the feeding cavity, so that the impurities are separated from the plastic masterbatch raw material, which can effectively solve the problems in the background technology.

[0022] The interior of the impurity removal box 1 is located directly below the material distribution plate 5 and is movably provided with a screening mesh plate 6. A rotating shaft 13 is installed on the inner wall of the impurity removal box 1. The rotating shaft 13 is movably connected to one end of the screening mesh plate 6. The screening mesh plate 6 is tilted downward, and the mesh of the screening mesh plate 6 is smaller than the diameter of the plastic masterbatch raw material.

[0023] The lower part of the other end of the screening mesh plate 6 is fixedly connected to the top of the spring 8 and the top of the movable baffle 9, and the spring 8 can protect the screening mesh plate 6 when it vibrates. The spring 8 is fixedly installed inside one side of the impurity removal box 1, and the movable baffle 9 is movably installed on the inner side of the impurity removal box 1. When the screening mesh plate 6 vibrates, it can drive the movable baffle 9 to move up and down. A discharge port 15 is provided on one side of the impurity removal box 1; one end of the dividing rod 3 is fixedly connected to the inner wall of one side of the impurity removal box 1, and the other end of the dividing rod 3 is fixedly connected to one side of the filter plate 16, and the filter plate 16 is fixedly installed on the upper part of the inner side of the impurity removal box 1.

[0024] The material distribution plate 5 is provided with a distribution opening 12, and the distribution opening 12 is provided at multiple locations.

First, the plastic masterbatch raw materials are put into the impurity removal box 1 through the feed port 2. The plastic masterbatch raw materials encounter multiple dividing rods 3 during the falling process, which will cause the final falling destination to be random and dispersed. During the falling process of the dividing rods 3, the exhaust fan 17 can be turned on by an external power supply. The exhaust fan 17 will remove the dust mixed in the plastic masterbatch raw materials. After the plastic masterbatch raw materials pass through the dividing rods 3, they will pass through different dividing ports 12 through different falling destinations, and finally fall into the top of the screening mesh plate 6 in a relatively dispersed manner.
