Description

Technical Field

[0001] This utility model relates to the field of cyclone technology, specifically a cyclone with a stirring and mixing structure. Background Technology

[0002] In the production process of cement, the material needs to be separated into gas and solid by a cyclone separator to meet the required production standards. However, the existing cyclone separators still have certain defects in use, such as:

[0003] Publication number CN202921224U proposes a cyclone mixing device for mixing materials, including a cyclone shell, a cyclone core, and a support frame. The cyclone shell has a tangential feed pipe along its outer wall. The upper end of the cyclone shell has a top cover. The cyclone core is a cylindrical body with openings at both ends, essentially a cylinder with a through hole along its center line. The cyclone core is connected to the top cover. A discharge port is located at the lower end of the cyclone shell, and a water inlet is provided on the feed pipe. This invention uses wind power to mix materials. The water inlet on the feed pipe of the cyclone allows granular materials to be fed into the cyclone through a material conveying pipe. Water is added during the feeding process, significantly improving mixing efficiency.

[0004] In the aforementioned document, materials and water are simply fed into the cyclone shell for mixing via airflow. During the mixing process, the materials tend to adhere to the inner wall of the cyclone shell and the outer wall of the cyclone core, forming clumps that affect the mixing effect. Therefore, a cyclone with a stirring and mixing structure is proposed to solve the above problems. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The cyclone separator with a stirring and mixing structure, by starting a pneumatic motor to drive the long and short scrapers to rotate, scrapes off the material from the inner wall of the cyclone separator body and the outer wall of the inner cylinder. After stirring, the material is sent out by an auger, thus ensuring uniform stirring within the cyclone separator with the stirring and mixing structure. Furthermore, the cyclone separator with the stirring and mixing structure filters the air discharged from the inner cylinder through a filter screen. Simultaneously, the rotating shaft drives the jet pipe to rotate and spray air, blowing off the material clogged by the filter screen, which is then brushed off by the brush plate, thus preventing dust discharge from the cyclone separator with the stirring and mixing structure. The specific details are as follows:

[0017] 1. By connecting the water pipe to the water pump, the water will be evenly distributed from the nozzle. The pneumatic motor is started to drive the rotating shaft. The rotating shaft drives the long scraper and the short scraper to scrape the material off the inner wall of the cyclone body and the outer wall of the inner cylinder, preventing the material from adhering to the inner wall of the cyclone body and the outer wall of the inner cylinder, thereby allowing the cyclone with the stirring and mixing structure to stir evenly.

[0018] 2. The air discharged from the inner cylinder is filtered through the filter screen, and air is circulated through the air supply pipe. The gas is sprayed out from the jet pipe, blowing off the material that is blocked by the filter screen. At the same time, the rotating shaft drives the brush plate to brush off the material attached to the bottom of the filter screen, thereby allowing the dust to be discharged from the cyclone with the stirring and mixing structure.
