[0002] PE granules are polyethylene granules, which are synthesized by chemical plants and are in granular form when shipped out of the factory, so they are called PE granules. Recycled polyethylene waste is also called PE granules after being crushed. When PE granules are produced, PE plastic granules need to be screened. PE plastic granules of different sizes are applicable.

[0003] For example, the patent application number CN202221194563.5 discloses a screening device for producing PE plastic particles with a multi-stage sorting structure, comprising: a screening device box, a power motor and an ash box, the right end of the screening device box is threadedly connected with a cleaning cover, the right end of the screening device box is fixedly installed with a connecting frame, the inner end of the connecting frame is slidably installed with a connecting water pipe, the power motor is fixedly installed at the left end of the screening device box, the output end of the power motor is fixedly installed with a gear, the outer end of the gear is meshed and connected with a chain, the front end of the gear is fixedly installed with an eccentric turntable, and the right end of the eccentric turntable is provided with a connecting plate.

DETAILED DESCRIPTION

[0018] Specific embodiment 1: Please refer to Figure 1-3 A screening device for producing PE plastic particles, comprising a shell 10; a cover 13 is clamped on the upper end of the shell 10; a feed port 14 is arranged at the center of the cover 13; a discharge port 12 is arranged at the lower side of the shell 10; a waterproof plug 11 is embedded in the shell 10 at the lower side of the discharge port 12; a second limit block 24 is fixedly arranged on the inner side of the shell 10 between the discharge port 12 and the waterproof plug 11; the upper end of the second limit block 24 abuts against a second filter plate 21; a limit block 1 23 is fixedly arranged on the inner side of the shell 10 at the upper end of the discharge port 12; the upper end of the limit block 1 23 abuts against a first filter plate 17; and an electric cylinder 20 is fixedly arranged on the upper end of the second filter plate 21; the output end of the electric cylinder 20 abuts against the lower end of the filter plate 17 The end faces are fixedly connected; four slide grooves 16 are fixedly arranged on the inner side of the shell 10 on the upper side of the filter plate 17; the filter plate 17 is embedded in the slide groove 16 and is slidably connected to the inner wall of the shell 10; the lower end face of the filter plate 17 is fixedly connected to the filter screen 19; the lower end of the filter screen 19 is fixedly connected to the lower end of the electric cylinder 20; the side of the filter plate 21 close to the discharge port 12 is lower than the side away from the discharge port 12; by arranging the filter plate 17, the filter screen 19, the electric cylinder 20, and the limit block 24, the electric cylinder 20 is used for rapid reciprocating motion, so that the filter screen 19 can be shaken to clean the PE plastic particles; the electric cylinder 20 is used for rapid reciprocating shaking to improve the screening efficiency of the filter plate 17.

[0019] See also Figure 2 The shell 10 is located at the lower side of the second limit block 24 and the heater 22 is fixedly arranged; the shell 10 is located at the lower side of the second limit block 24 and is filled with distilled water.

[0020] See also Figure 2 , the filter screen 19 is made of rubber.

[0021] See also Figure 2 The filter plate 17 is a hemispherical stainless steel mesh plate.

[0022] See also Figure 2 A pulse jet valve 15 is fixedly arranged at the upper end of the upper cover 13; a heater 22 is arranged at the lower end of the inner side of the outer shell 10 to evaporate water to produce water vapor, and the water vapor is combined with the high-pressure pulse gas ejected from the pulse jet valve 15 to improve the cleaning effect on the PE plastic particles.

[0023] During operation, PE plastic particles are poured from the feed port 14 into the inner side of the housing 10, and then the electric cylinder 20 is started. The output end of the electric cylinder 20 pushes the filter plate 17 to move back and forth inside the slide 16. As the filter plate 17 moves up and down quickly, the PE plastic particles falling on the filter plate 17 shake, and relatively fine particles fall from the filter plate 17 and fall onto the filter screen 19; as the filter plate 17 moves up and down quickly, the filter screen 19 is pulled quickly, and the filter screen 19 close to the electric cylinder 20 is pulled, and the mesh on the filter screen 19 is stretched and expanded. In the process of the particles being quickly shaken by the filter screen 19, the dust on the particles is shaken off, and the particles finally fall onto the filter plate 21, and the particles are finally discharged from the discharge port 12, and smaller particles and impurities fall downward to the lower side of the limit block 24;

[0024] When the PE plastic particles are stained with a lot of dust, the pulse jet valve 15 and the heater 22 are started after the PE plastic particles are put into the feed port 14. The heater 22 is used to evaporate the moisture near the limit block 24, and the hot water vapor is used to fumigate the PE plastic particles. Then the water vapor condenses into water after encountering the PE plastic particles, and finally falls from the filter plate 21; after the pulse jet valve 15 is started, the inner side of the shell 10 is intermittently pulse-jetted to wash away the dust stuck on the PE plastic particles, and the high-pressure pulse gas and water vapor are combined to clean the PE plastic particles and improve the screening effect.

[0025] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0026] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the product or system including the elements.
