Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust removal equipment for plastic pellet production. Background Technology
[0002] Plastic granules refer to granular plastics, generally classified into over 200 types, with thousands of subcategories. Common plastic granules include general-purpose plastics, engineering plastics, and specialty plastics. General-purpose plastics include polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, and polyurethane. During the production of plastic granules, processes such as raw material mixing, extrusion, and pelletizing generate a large amount of dust. This dust not only affects the production environment and harms the health of operators but also leads to a decline in product quality and even poses a dust explosion hazard. Therefore, dust removal equipment has become an indispensable and important component of plastic granule production lines. Existing plastic granule dust removal equipment uses simple negative pressure dust collection, relying solely on wind power to suck away dust from the air. However, dust adhering to the surface of the plastic granules is not effectively treated, resulting in numerous dust collection dead zones, poor dust removal efficiency, and an inability to achieve high-efficiency and energy-saving dust removal. Utility Model Content
[0003] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a dust removal device for plastic pellet production.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A dust removal device for plastic pellet production includes a mounting plate and a support plate. The support plate is fixed to the middle of the upper surface of the mounting plate. A collection box is embedded in the lower part of the support plate. An outer cylinder is horizontally fixed to the upper surface of the support plate. A vacuum cleaner is fixed to the top of the outer cylinder. Servo motors are fixed to the left and right ends of the upper surface of the mounting plate via brackets. A stirring motor is fixed to the middle of the right side of the outer cylinder. A stirring rod is horizontally embedded in the middle of the outer cylinder. A main stirring blade and a secondary stirring blade are fixed to the outer wall of the stirring rod. Connecting rings are embedded in the left and right ends of the inner part of the outer cylinder. An inner cylinder is fixed between the two connecting rings.
[0006] Preferably, the gear disk at the power output end of the servo motor meshes with the teeth on the inner wall of the connecting ring, the inner cylinder rolls clockwise in the outer cylinder, and the power output end of the stirring motor is connected to the stirring rod in a counterclockwise direction via a transmission shaft.
[0007] Preferably, the inner cylinder has several slag discharge holes inside, and the collection box is located at the middle of the bottom end of the inner cylinder.
[0008] Preferably, the auxiliary stirring blade is disposed outside the main stirring blade, and the main stirring blade and the auxiliary stirring blade are arranged in a ring around the middle of the stirring rod.
[0009] Preferably, the outer wall of the auxiliary stirring blade is in close contact with the inner wall and right side of the inner cylinder, and a large opening is provided in the middle of the auxiliary stirring blade.
[0010] Preferably, the distance between the outer wall of the inner cylinder and the inner wall of the outer cylinder is 10-20cm, and the air inlet of the vacuum cleaner is connected to the interior of the outer cylinder through a pipe.
[0011] During the dust removal process, the servo motor drives the inner cylinder to rotate clockwise via the gear disk and connecting ring. This causes the plastic particles inside the inner cylinder to roll along with the cylinder. Simultaneously, the stirring motor drives the main and auxiliary stirring blades on the stirring rod to rotate counterclockwise, agitating and dispersing the plastic particles. This also prevents some plastic particles from accumulating at the bottom of the inner cylinder for extended periods. As the plastic particles roll and are agitated, heavier dust particles fall through the slag discharge hole inside the inner cylinder into the collection box for storage. At the same time, the vacuum cleaner collects the lighter dust particles that fall through the slag discharge hole through a pipe. There are no dead corners in the dust removal process, resulting in excellent dust removal efficiency. Attached Figure Description

[0017] Mounting plate 1, support plate 2, collection box 201, outer cylinder 202, vacuum cleaner 203, servo motor 204, stirring motor 3, stirring rod 301, main stirring blade 302, auxiliary stirring blade 303, connecting ring 4, inner cylinder 401. Detailed Implementation
[0018] Example 1, referring to Figures 1-4A dust removal device for plastic pellet production includes a mounting plate 1 and a support plate 2. The support plate 2 is fixed to the middle of the upper surface of the mounting plate 1. A collection box 201 is embedded in the lower part of the support plate 2. An outer cylinder 202 is horizontally fixed to the upper surface of the support plate 2. A vacuum cleaner 203 is fixed to the top of the outer cylinder 202. Servo motors 204 are fixed to the left and right ends of the upper surface of the mounting plate 1 through brackets. A stirring motor 3 is fixed to the middle of the right side of the outer cylinder 202. A stirring rod 301 is horizontally embedded in the middle of the outer cylinder 202. A main stirring blade 302 and a secondary stirring blade 303 are fixed to the outer wall of the stirring rod 301. Connecting rings 4 are embedded in the left and right ends of the inner cylinder 202. An inner cylinder 401 is fixed between the two connecting rings 4.
[0019] The gear disk at the power output end of the servo motor 204 meshes with the teeth on the inner wall of the connecting ring 4, and the inner cylinder 401 rolls clockwise in the outer cylinder 202. The power output end of the stirring motor 3 is connected to the stirring rod 301 in a counterclockwise direction through the transmission shaft.
[0020] After the plastic granules are poured into the inner cylinder 401, the cover is closed. The servo motor 204 drives the inner cylinder 401 to rotate clockwise through the gear disk and connecting ring 4, so that the plastic granules in the inner cylinder 401 rotate inside the inner cylinder 401 as the inner cylinder 401 rotates. While the plastic granules are rotating clockwise, the stirring motor 3 drives the main stirring blade 302 and the auxiliary stirring blade 303 on the stirring rod 301 to rotate counterclockwise, so that the main stirring blade 302 and the auxiliary stirring blade 303 stir the plastic granules and disperse the plastic granules, so as to avoid a large amount of dust sticking to the surface of the plastic granules.
[0021] The inner cylinder 401 has several slag discharge holes inside, and the collection box 201 is located at the bottom center of the inner cylinder 401.
[0022] The auxiliary stirring blade 303 is disposed outside the main stirring blade 302, and the main stirring blade 302 and the auxiliary stirring blade 303 are arranged in a ring around the middle of the stirring rod 301;
[0023] The outer wall of the auxiliary stirring blade 303 is in close contact with the inner wall and right side of the inner cylinder 401, and a large opening is provided in the middle of the auxiliary stirring blade 303.
[0024] While agitating the plastic granules, the auxiliary stirring blade 303 can prevent some plastic granules from accumulating at the bottom of the inner cylinder 401 for a long time, so that there are no dead corners for dust removal and the dust removal effect is better.
[0025] Example 2 differs from Example 1 in that, in this example, the distance between the outer wall of the inner cylinder 401 and the inner wall of the outer cylinder 202 is 10-20cm, and the air inlet of the vacuum cleaner 203 is connected to the interior of the outer cylinder 202 through a pipe.
[0026] As the plastic granules roll and are agitated, the heavier dust inside them falls through the slag discharge hole inside the inner cylinder 401 and is stored in the collection box 201. At the same time, the vacuum cleaner 203 draws in and collects the lighter dust that falls through the slag discharge hole through the pipe, preventing the dust from scattering everywhere and achieving a good dust removal effect.
[0027] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
