Description

Technical Field

[0001] This utility model relates to the field of high-speed dispersers, and in particular to a high-speed disperser for color masterbatch raw materials. Background Technology

[0002] Masterbatch, also known as colorant or colorant granules, is a new type of colorant specifically for polymer materials, also called pigment preparation. Masterbatch is mainly used in plastics. It consists of three basic elements: pigment or dye, carrier, and additives. It is an aggregate made by uniformly loading an extraordinary amount of pigment into resin, and can be called a pigment concentrate, therefore its coloring power is higher than that of the pigment itself. During processing, a small amount of masterbatch is mixed with uncolored resin to achieve the designed pigment concentration in the resin or product.

[0003] Currently, there are technologies for preparing masterbatches with high pigment concentrations. For example, Chinese patent CN114561031B discloses a high-pigment-content masterbatch, its preparation method, and its application. The prepared masterbatch has a high pigment concentration. During melt spinning, this masterbatch can extend the screen changing cycle of the spinning process, reduce filament drift and breakage, and has the advantages of low material consumption and low impact. Before producing this masterbatch through an extruder, the masterbatch raw material needs to be stirred evenly to ensure the dispersibility and coloring power of the masterbatch. However, ordinary mixers do not thoroughly stir the masterbatch raw material. Although most of the masterbatch in the same mixing tank has been stirred evenly, the masterbatch raw material at the edge of the mixing tank has not been thoroughly stirred, which will affect the performance of the masterbatch and needs to be improved. Utility Model Content

[0004] In order to ensure that the color masterbatch raw materials are thoroughly mixed and uniformly mixed in the mixing tank, this application provides a high-speed disperser for color masterbatch raw materials.

[0006] A high-speed disperser for color masterbatch raw materials includes a frame, a stirring assembly mounted on the frame, and a drive motor mounted on the frame. The stirring assembly includes a stirring box mounted on the frame and a stirring roller rotatably connected to the stirring box. A support plate is provided below the stirring roller, and a first processing chamber for accommodating the color masterbatch raw materials is provided above the support plate. A second processing chamber is provided below the support plate. The support plate includes a fixed plate fixed to the stirring box and a sliding plate slidably connected to the stirring box. The sliding plate closes or opens the second processing chamber. The drive motor drives the stirring roller to rotate. A plurality of adjusting rollers are provided in the second processing chamber, and the plurality of adjusting rollers are arranged at intervals along the length direction of the stirring roller. When the color masterbatch raw materials fall from the first processing chamber into the second processing chamber, the adjusting rollers stir the color masterbatch raw materials.

[0007] Preferably, the outer wall of the adjusting roller is provided with several sets of stirring protrusions, the several sets of stirring protrusions are arranged at equal intervals along the length direction of the adjusting roller, and the several stirring protrusions in each set are arranged at equal intervals along the outer peripheral wall of the adjusting roller.

[0008] Preferably, a passage area is provided between adjacent stirring protrusions on the same regulating roller, and the passage areas between adjacent regulating rollers are spaced apart.

[0009] Preferably, the second processing chamber is provided with an inclined surface, which is inclined downward in a direction away from the drive motor. The adjusting roller is spaced apart from the inclined surface. When the adjusting roller rotates to the point where the stirring protrusion is close to the inclined surface, the stirring protrusion contacts the inclined surface.

[0010] Preferably, it also includes auxiliary components, which include a collection cylinder, a stirring rod, a stirring impeller, and a stirring motor. The stirring motor is located at the bottom of the collection cylinder and is used to drive the stirring rod to rotate. The stirring impeller is fixed to the outer wall of the stirring rod and is located at the top of the stirring rod. A discharge port is provided on the bottom wall of the second processing chamber, and a discharge pipe is provided at the discharge port. A discharge valve is provided on the discharge pipe, and the discharge valve is used to open or close the discharge pipe.

[0011] Preferably, the tank wall of the mixing tank is provided with a sliding groove for the sliding plate to slide; the sliding plate is provided with a connecting protrusion on the side facing the fixed plate, and the fixed plate is provided with a connecting groove on the side facing the sliding plate for the connecting protrusion to be accommodated.

[0012] Preferably, the mixing tank is provided with a vent, and a feed hopper is provided at the vent.

[0013] The main technical effects of this utility model are reflected in the following aspects:

[0014] 1. This utility model uses a stirring roller to mix and stir a large amount of color masterbatch material in the first processing chamber. After a period of time, the sliding plate is pulled out to open the second processing chamber. The color masterbatch material is then uniformly stirred by a number of adjusting rollers in the second processing chamber.

[0015] 2. This utility model sets an inclined surface so that the color masterbatch material falls onto the bottom wall of the second processing chamber along the inclined surface. At this time, the color masterbatch material can be guided and stirred by the adjusting roller to make the color masterbatch material uniform.

[0016] 3. This utility model incorporates an auxiliary component to re-stir the color masterbatch material during collection, resulting in a more uniform color masterbatch material. Attached Figure Description
