DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] Example

[0020] like Figure 1 、 Figure 2 As shown, Figure 1 Shown is a schematic diagram of the main structure of the screening device in the embodiment; Figure 2 What is shown is a schematic structural diagram of a cleaning component in an embodiment;

[0021] The device includes:

[0022] The box body 10 is provided with a screen 1 21 with a first hole 210 and a screen 2 22 with a second hole 220. The screen 2 22 is provided below the screen 1 21, and the diameter of the second hole 220 is smaller than that of the first hole 210.

[0023] The cleaning component 30 includes a main rod 31 that is vertically rotatable and arranged in the box body 10. The main rod 31 passes through the screen 1 21 and the screen 2 22. The outer surface of the main rod 31 and the position below the screen 1 21 and the screen 2 22 are respectively provided with a mounting rod 33 with the same shape as the screen 1 21 and the screen 2 22. The mounting rod 33 is provided with a brush 34 at one end close to the screen 1 21 and the screen 2 22.

[0024] Screen 1 21 and screen 2 22 divide the box 10 into three screening zones by opening meshes of different diameters, which plays a role in screening and grading. The diameter of hole 1 210 is larger than that of hole 2 220, so that after the masterbatch falls into each screening zone, the particle diameter decreases from top to bottom.

[0025] Specifically, the screen 1 21 and the screen 2 22 are both arched, and the brushes 34 below the screen 1 21 and the screen 2 22 are respectively in contact with the screen 1 21 and the screen 2 22. When the main rod 31 rotates, the mounting rod 33 and the brush 34 rotate synchronously. At this time, the brush 34 can clean the screen 1 21 or the screen 2 22 in contact with it;

[0026] By setting up the cleaning component 30, the brush 34 can continuously clean the screen 1 21 and the screen 2 22 during the screening process, thereby removing the attachments and impurities accumulated on the filter screen, avoiding the accumulation of impurities on the filter screen to block the mesh or reduce the effective area of ​​the mesh, and improving the working efficiency of the filter screen.

[0027] At the same time, the bristles of the rotating brush 34 can continuously extend into the mesh, and can also prevent the masterbatch itself from clogging the mesh.

[0028] like Figure 1 、 Figure 2 As shown, Figure 1 Shown is a schematic diagram of the main structure of the screening device in the embodiment; Figure 2 What is shown is a schematic structural diagram of a cleaning component in an embodiment;

[0029] The outer surface of the main rod 31 is provided with a plurality of stirring blades 32;

[0030] The stirring blades 32 play a stirring role during the screening process of the masterbatch, which can accelerate the separation of the masterbatch on the one hand, and prevent the masterbatch from sticking to each other on the other hand, thereby further improving the screening efficiency. Specifically, the stirring blades 32 are provided on the outside of a section of the main rod 31 located in each screening area.

[0031] The two ends of the main rod 31 are respectively connected to the box body 10 for rotation. A motor 35 is further provided at the top of the box body 10. The output end of the motor 35 is connected to the main rod 31, and the motor 35 drives the main rod 31 to rotate.

[0032] like Figure 1 As shown, Figure 1 Shown is a schematic diagram of the main structure of the screening device in the embodiment;

[0033] It also includes a base 1 arranged at the bottom end of the box body 10, and a fan 40 is also arranged on the base 1. The output end of the fan 40 is connected to the heating box 42, and also includes an air supply pipe 41 connected to the other end of the heating box 42, and the end of the air supply pipe 41 is inserted into the interior of the box body 10.

[0034] The blower 40, the heating box 42, and the air duct 41 cooperate to deliver hot air into the box 10, thereby drying the masterbatch screened inside the box 10. Specifically, the air blown by the blower 40 is heated by the heating box 42 and then delivered to the inside of the box 10 through the air duct 41.

[0035] A feed port 11 is provided at the top of the box body 10 , and a discharge port 12 is provided on the box body 10 corresponding to each screening cavity, and a blocking rod is movably inserted into the discharge port 12 .

[0036] The discharge port 12 is convenient for discharging the masterbatches of various levels after screening; the blocking rod plays the role of temporarily closing the discharge port 12 so that the discharge port 12 can be opened again when discharging is needed.

[0037] Working principle: When the device is in use, the masterbatch that needs to be screened and dried is poured into the interior of the box 10 from the feed port 11 of the box 10. Under the action of gravity, the masterbatch, combined with the screen 1 21 and the screen 2 22, enters different screening areas according to the size of its own particles. At the same time, the motor 35 is started, and the motor 35 drives the main rod 31 to rotate. The main rod 31 drives the stirring blade 32 and the brush 34 to rotate synchronously. The brush 34 can remove the attachments and impurities on the screen 1 21 and the screen 2 22, thereby preventing the mesh from being blocked.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
