Embodiment 1

[0040] see figure 1 and 2 As shown, the present invention is a kind of screening device for plastic particle raw material, comprises frame 1, and frame 1 comprises flat plate, and flat plate is supported by several pillars; Frame 1 is fixedly connected with screening tube 2 by welding or bolt; Screening tube The lower end of 2 is rounded, and the lower end of the screening cylinder 2 runs through the lower surface of the plate.

[0041] like Figure 3-5 As shown, the discharge pipe 3 is rotatably connected in the screening cylinder 2, and the discharge pipe 3 is concentrically arranged with the screening cylinder 2; the outer wall of the upper end of the discharge pipe 3 is rotatably connected with a fan-shaped fixing plate 301, and the arc length of the fan-shaped fixing plate 301 is Excellent arc; the fixed plate 301 is welded to the inner wall of the screening cylinder 2 or fixedly connected by bolts; the outer wall of the lower end of the discharge pipe 3 rotates with a ...

Embodiment 2

[0059] like Figure 3-9 As shown, on the basis of Embodiment 1, the cross-sectional shape of the upper sieve tray 5 and the lower sieve tray 6 is trumpet-shaped, and the flared end is set upward; The upper surface of the lower sieve tray 6 is flush with the discharge opening 405 .

[0060] The side walls of the discharge pipe 3 are respectively provided with discharge ports 303 corresponding to the two discharge ports 405; and the angle between the two discharge ports 303 in the horizontal direction is 90°-180°; the upper end of the discharge pipe 3 runs through the fixed plate 301, And the upper end face is welded with a turning handle 304.

[0061] After the screening is completed, the plastic particles remaining on the upper sieve tray 5 and the lower sieve tray 6 are gathered at the position of the discharge port 405, and the discharge pipe 3 is rotated by the handle 304, so that the upper discharge port 303 and the upper sieve tray After the discharge ports 405 at the 5...

Abstract

The invention discloses a screening device for plastic particle raw materials, which relates to the technical field of plastic production. The invention comprises a screening cylinder; a discharge pipe is rotatably connected in the screening cylinder; a sieve coil tube is set on the outer wall of the discharge tube; springs are set on the upper and lower ends of the discharge tube, and the spring is in contact with the end surface of the sieve coil tube; The outer wall of the coil tube is rotatably connected with an upper sieve tray and a lower sieve tray distributed up and down; the side walls of the sieve tray tube are respectively provided with discharge ports flush with the upper surfaces of the upper sieve tray and the lower sieve tray; the side walls of the discharge pipe are respectively provided with There are discharge ports corresponding to the two rows of discharge ports. The invention solves the problem that the existing screening equipment can only screen particles of one size by rotating and connecting the upper sieve tray and the lower sieve tray on the sieve tray tube, and setting sieve holes of different sizes on the upper sieve tray and the lower sieve tray. Poor adaptability and practicality. By setting the discharge port on the sieve coil tube and the corresponding discharge port on the discharge pipe, the existing problem of manually collecting retained particles and affecting the screening efficiency is solved.

Description

technical field [0001] The invention belongs to the technical field of plastic production, in particular to a screening device for plastic particle raw materials. Background technique [0002] Plastic granules need to be stirred, heated and mixed in plastic processing. However, the sizes of plastic granules are different. In order to improve the mixing effect, it is necessary to screen the plastic granules, so that the plastic granules of the same size can be stirred and mixed to improve the mixing effect. [0003] However, the existing screening equipment is only capable of screening plastic particles of a fixed size, and cannot adjust the screening of different particle sizes according to needs, resulting in poor adaptability and practicability of the screening device. At the same time, after the screening is completed, the existing screening equipment needs to manually collect the plastic particles retained on the screening net or screening plate. Due to the limitation of...
