Description

Technical Field

[0001] This utility model belongs to the field of waste film plastic production technology, specifically relating to a waste film plastic air separation machine. Background Technology

[0002] In recent years, the application of plastic products has become increasingly widespread both domestically and internationally. However, waste plastics are not easily decomposed and can seriously impact the human ecological environment. Therefore, people have begun to recycle and reuse waste plastics. However, before reuse, waste plastics must be crushed into plastic film fragments, then washed and dried. The dried material is then extruded through a waste plastic film extruder to produce various products, ensuring product quality.

[0003] In existing technologies, greenhouses use a large amount of film, and the quantity of film is enormous. When recycling film, the recycled film contains some dry grass, wood, powder, and dust, which are difficult to separate from the film. Therefore, there is an urgent need to design a waste film plastic air classifier to deal with these problems. Utility Model Content

[0024] In this embodiment: the separation actuator 2 includes a first square box 201 fixedly mounted above the base 1. A feeding pipe 202 is installed above the first square box 201. A stepped rotating shaft 204 is horizontally arranged inside the first square box 201. A material pushing and dispersing component is installed on the outer surface of the stepped rotating shaft 204. A first motor 203 is installed at one end of the stepped rotating shaft 204. A first filter screen 205 is installed on the first square box 201. A dust extraction component is installed on the first filter screen 205. A separation chamber 208 is installed on one side of the lower end of the first square box 201.

The dust extraction assembly includes a first dust collection box 206 disposed on the first filter screen 205, and an exhaust fan 207 disposed on one side of the first dust collection box 206. The airlock fan is typically used in pneumatic conveying systems. For pressure or negative pressure conveying systems, the airlock fan can uniformly and continuously supply material to the conveying pipe to ensure a stable gas-solid ratio within the pneumatic conveying pipe. This allows the pneumatic conveying system to operate normally while simultaneously isolating the upper and lower air pressures of the airlock fan, thus acting as an airlock. Therefore, the airlock fan is a commonly used and important component in pneumatic conveying systems and is existing technology.

[0025] In this embodiment: the collection mechanism 3 includes a second square box 301 disposed on one side of the separation execution mechanism 2. A lightweight material conveying duct 302 is disposed between the second square box 301 and the separation execution mechanism 2. A second filter screen 303 is installed inside the second square box 301. A lightweight material separation component is horizontally disposed below the second filter screen 303. A lightweight material discharge pipe 306 is installed at the lower end of the second square box 301. A discharge fan 3061 is installed on the lightweight material discharge pipe 306. A discharge box is disposed at the lower end of the discharge fan 3061. A dust collector 307 is disposed on one side of the second square box 301. An induced draft fan 308 is installed on the dust collector 307. A return air regulating component is installed at the output end of the induced draft fan 308. The lightweight material separation component includes a lightweight material separation cylinder 304 horizontally disposed below the second filter screen 303. The outer surface of the lightweight material separation cylinder 304 is uniformly provided with grate holes 3041. A second motor 305 is disposed at one end of the lightweight material separation cylinder 304. The return air regulating component includes a return air supply duct 309 located at the output end of the induced draft fan 308, and a regulating valve 310 installed on the return air supply duct 309. The airflow of the return air supply duct 309 is adjusted by regulating the valve 310 as needed to maintain the separation chamber 208 in working condition. A dust collector 307 is installed with a dust collection rack. The dust collector 307 is connected to the lightweight material separation cylinder 304 via a hollow duct and is installed through one end of the lightweight material separation cylinder 304. The induced draft fan 308 is a device that generates negative pressure through impeller rotation, thereby drawing air from the system equipment. Ventilation fans are typically classified according to their positive or negative pressure operation: induced draft fan 308 for negative pressure operation and blower fan for positive pressure operation. This design, which involves both return airflow blowing and induced draft airflow extraction, significantly improves the separation capacity of lightweight materials and is a current technology.

[0026] Working Principle: During operation, the waste film plastic is first pre-processed. Then, the first motor 203 is started, driving the stepped rotating shaft 204 and the pushing spiral blade segment 2041 and the dispersing spiral blade segment 2042 on the outer surface to rotate. The pre-processed waste film plastic is fed into the first container 201 through the feeding pipe 202. The exhaust fan 207 is started, and the waste film plastic, impurities, and dust from the pushing and dispersing are pre-cleaned through the first filter screen 205 and the first dust collection box 206. Simultaneously, the induced draft fan 308 is started, and the airflow in the return air supply pipe 309 is adjusted by the regulating valve 310, blowing air onto the rotating waste film plastic and impurities in the first container 201. To enhance the airflow in the separation chamber 208, the blower 209 is started to separate the material falling into the separation chamber 208. Heavy materials that cannot be blown or sucked by the airflow fall to the heavy material receiving box 210 under gravity and are then sent to the rear... Continued processing: Lightweight materials are blown by the airflow from the return air supply duct 309 and drawn in by the induced draft fan 308 and the blower 209. Large-sized lightweight materials are blown off and fall into the large-sized lightweight material receiving box below via the lightweight material discharge shut-off fan 212. The lightweight material suction inlet switch 211 is opened, and small-sized lightweight materials and uncleaned dust are sucked into the lightweight material conveying duct 302 and sent to the lightweight material separation cylinder 304 driven by the second motor 305. After separation in the airflow, the material falls into the lightweight material discharge pipe 306. By opening the discharge fan 3061, it falls into the discharge box. After the lightweight material is separated, the dust-laden airflow enters the dust collector 307 for dust removal. The airflow from the outlet of the induced draft fan 308 is regulated by the regulating valve 310 and then sent back to the separation chamber 208 via the return air supply pipe 309. The airflow in the return air supply pipe 309 is adjusted by the regulating valve 310 as needed to maintain the separation chamber 208 in operation. Adjusting the regulating valve 310 as needed leads to the return air supply pipe, and some of the airflow in 309 enters the blowing pipe to purge the filter rollers on the lightweight material separation cylinder 304, completing the air separation of waste film plastic.
