Embodiment 1

[0043] refer to Figure 1-6 , a screening and dedusting device for multifunctional modified plastic granulation, comprising a body shell 1, an upper end cover 2 and a screening frame 3, the upper end cover 2 is fixedly arranged on the upper end of the body shell 1, and on the top of the upper end cover 2 a There is a feed inlet on the side, and the feed inlet is located directly above the first screen 401, which is used for feeding and screening modified plastic particles. The screening frame 3 is arranged in the body shell 1, and the screening frame 3 The bottom is provided with a grading screen 4, and both sides of the outer wall of the grading sieve 4 are symmetrically provided with limiting parts 5. The limiting parts 5 provide limit support for the screening frame 3, thereby ensuring that the screening frame 3 can shake smoothly and horizontally. There are several groups of damping springs 21 connected between the component 5 and the inner side wall of the body shell 1, a...

Embodiment 2

[0054] refer to Figure 1-6 The difference between this embodiment and Embodiment 1 is that the body shell 1 is provided with a dust suction port relative to the other side wall of the vacuum cleaner 24, the dust suction port communicates with the side wall of the screening frame 3, and a metal suction port is arranged inside the dust suction port. The filter screen, the outward extension of the dust suction port is connected with a dust removal device, and the dust removal device is a pulse dust collector of the SCT4-550 type;

[0055] The two side walls of the bottom of the cleaning frame 20 are respectively provided with several groups of concave tooth grooves, which are used to evacuate and push the plastic particles, which is helpful for the removal of dust and impurities;

[0056] The side wall of the cleaning frame 20 is provided with a top plate 25 through the cavity 27, and the top side of the top plate 25 is provided with a wedge 26, and the wedge 26 extends inwardly...

Abstract

The invention discloses a multifunctional screening and dust removing device for modified plastic granulation, which comprises a machine body shell, an upper end cover and a screening frame body; the upper end cover is fixedly arranged at the upper end of the machine body shell; the screening frame body is arranged in the machine body shell; a classifying screen is arranged at the bottom of the screening frame body; limiting components are symmetrically arranged on the two sides of the outer wall of the classifying screen, and a plurality of sets of damping springs are connected between the limiting components and the inner side wall of the machine body shell; a mounting groove is arranged on the lower end face of the upper end cover; a reciprocating lead screw is horizontally arranged in the mounting groove; the outer wall of the reciprocating lead screw is sleeved with a moving rod in a threaded mode; and a sweeping frame is fixedly arranged at the bottom of the moving rod. The multifunctional screening and dust removing device for the modified plastic granulation provided by the invention overcomes the defects in the prior art, is reasonable in design, can conduct multi-particle-size screening on modified plastic particles, facilitates bagging and collection, meanwhile, conducts dust removal and adsorption on generated dust, purifies the air environment, and has high social use value and application prospects.

Description

technical field [0001] The invention relates to the technical field of production and processing of modified plastics, in particular to a screening and dust removal device for granulating multifunctional modified plastics. Background technique [0002] Modified plastics refer to plastic products that are processed and modified on the basis of general-purpose plastics and engineering plastics through filling, blending, reinforcement, etc., and have improved properties such as flame retardancy, strength, impact resistance, and toughness. [0003] The plastic granulation process includes the following steps: the molten polymer is extruded from the die, cooled by a horizontal cooling water tank to form plastic strips, and then the plastic strips are cut into pellets by a rotary knife, and the pellets are taken out by temperature-adjusted water The pelletizing chamber enters the centrifugal dryer, and the pellets pass through the centrifugal dryer to remove moisture. [0004] Th...
