Description

Technical Field

[0001] This utility model belongs to the field of general equipment technology, and specifically relates to a material air separation device. Background Technology

[0002] Currently, rubber caps are mainly produced using compression molding technology. In this process, the raw material undergoes pressure vulcanization within a mold. After molding, the rubber caps must be demolded and have their edges trimmed. After trimming, the finished rubber caps and the scrap trimming material are usually mixed together before screening. The finished rubber caps have a relatively regular shape, while the scrap trimming material varies in shape. After molding, the scrap trimming material is usually flat, resulting in a significant difference in air resistance between the finished rubber caps and the scrap trimming material. Based on this characteristic, the industry typically uses air separators to separate the finished rubber caps from the scrap trimming material.

[0003] An air separator is an industrial device that uses airflow to separate materials of different densities, particle sizes, or shapes. It is widely used in agriculture, mining, recycling, environmental protection, and food processing. Its core principle is to control the speed and direction of the airflow so that lighter materials are carried away by the airflow, while heavier materials settle naturally, thus achieving efficient separation.

[0004] Air classifiers can be classified into horizontal air classifiers and vertical air classifiers according to their structure. Because finished rubber caps are prone to lateral displacement under wind force, horizontal air classifiers are less commonly used for screening finished rubber caps and scrap. Vertical air classifiers are more commonly used for screening and separating finished rubber caps and scrap.

[0005] The working principle of a vertical air classifier is as follows: Material is contained within a single vertical chamber, and a blower blows air, causing the material to circulate randomly within the chamber. After a period of this random movement, waste material enters the discharge channel, completing the screening and separation process. Current technology typically requires a high-powered blower and a large vertical chamber space to achieve this screening. A larger vertical chamber provides sufficient space for the random circulation, while a high-powered blower provides the power. However, due to the significant difference in air resistance between finished rubber caps and flash waste, a smaller blower can be used to separate the two materials, achieving miniaturization and low power consumption. This miniaturization and low power consumption of the air classifier is usually achieved by reducing the volume of the vertical chamber and using a smaller blower. The material to be screened flows unidirectionally through the vertical chamber, while the flash waste is separated by the airflow, thus completing the screening process. However, this type of air classifier has a major drawback when in use. The material enters the vertical chamber from the feed inlet, and the air flows from the bottom to the top of the vertical chamber. The material falls from top to bottom, and the material at the top will hinder the upward movement of the flash waste with the airflow, resulting in incomplete separation of the rubber cap material and the flash waste.

[0006] In order to solve the above problems, this utility model aims to provide a material air separation device. Utility Model Content

[0007] The purpose of this invention is to provide a material air separation device to solve the problems mentioned in the background art.

[0018] (1) The material air separation device provided by this utility model has several material feeding dividers inside the vertical track. The material feeding dividers are arranged in a zigzag pattern. The material feeding dividers can reduce the direct falling of rubber cap material. When the rubber cap material falls onto the material feeding dividers, the rubber cap material will change its falling direction.

It effectively solves the problem that the flash waste is hindered from separating with the airflow when the rubber cap material falls normally.

[0019] (2) The material air separation device provided by this utility model includes a feeding divider comprising several neatly arranged screening bars. This design enables airflow to pass smoothly through the feeding divider, which can effectively improve screening efficiency.

[0020] (3) The material air separation device provided by this utility model has a U-shaped channel II between the blower and the vertical channel.

A second U-shaped channel 5 is connected to the lower opening of the vertical channel 4, and the other end of the second U-shaped channel 5 is fixedly connected to the blower 2. The airflow from the blower 2 passes through the second U-shaped channel 5, the vertical channel 4, and the first U-shaped channel 3 in sequence. To support the inverted U-shaped channel 3, a support frame 6 is provided between the two ends of the U-shaped channel 3.

[0031] A feed inlet 8 is located on the upper side wall of the vertical channel 4, and a feed track 9 is connected to the feed inlet 8. Initial material enters the air-separating channel 1 through the feed track 9 and the feed inlet 8. To prevent excessive airflow escape from the air-separating channel 1, the feed inlet 8 is a long, narrow, straight design with a relatively low height. Inside the vertical channel 4, there are five obliquely arranged discharge dividers 10 and one guide divider 11.
