Natural rubber deaminating device

Abstract

This application provides a natural rubber ammonia removal device, relating to the field of rubber ammonia removal technology. This application uses a drive component to drive a support frame to rotate. When the support frame rotates, it causes two rotating shafts and a stirring frame to revolve. Simultaneously, the support frame drives a second end-face gear to rotate on a second end-face gear ring via a connecting shaft. During this process, the second end-face gear and the second end-face gear ring cooperate to drive the connecting shaft and the first end-face gear ring to rotate. The rotation of the first end-face gear ring drives two first end-face gears to rotate, which in turn drive the rotating shaft and the stirring frame to rotate. By employing a combined rotation and revolution stirring method, compared to the traditional single rotation stirring method, the stirring effect is enhanced, thereby accelerating ammonia volatilization and improving ammonia removal efficiency.

Description

Technical Field

[0001] This utility model relates to the field of rubber deammoniation technology, and more specifically, to a device for deammoniation of natural rubber. Background Technology

[0002] Natural rubber, as an important industrial raw material, has a wide range of applications in many fields. During the processing of rubber, the rubber contains a certain amount of ammonia, and the presence of ammonia has a significant impact on subsequent processing and product quality. At present, ammonia removal (strictly speaking, ammonia reduction) is an essential processing procedure in rubber processing. By reducing the ammonia content in the rubber, the amount of coagulant can be reduced, thereby effectively improving the product quality of the rubber. The commonly used ammonia reduction methods in the existing technology mainly include in-tank stirring (or supplemented by mechanical blowing) ammonia reduction method, trough ammonia reduction method, and surface (surface layer) mechanical blowing ammonia reduction method, etc.

[0003] However, traditional devices typically employ a single-shaft rotation mixing method, meaning the mixing shaft only rotates around its own axis. This limits the mixing range to the circumference of the shaft, resulting in uneven mixing between the center and the edges, and a limited contact area between the rubber and air. Therefore, we have made improvements and proposed a natural rubber ammonia removal device. Utility Model Content

[0004] This utility model provides a device for removing ammonia from natural rubber, including a mixing tank and a protective cover installed on top of the mixing tank. The protective cover is connected to a driving component, and the driving component is connected to a support frame located inside the protective cover. A connecting shaft is connected to the support frame, and a first end face gear ring located inside the support frame is fixedly installed on the outer surface of the connecting shaft. Both sides of the first end face gear ring are meshed with first end face gears. A rotating shaft is fixedly connected to the middle of each of the two first end face gears. The bottom ends of the two rotating shafts pass through the support frame and are fixedly connected to a mixing frame. A second end face gear is connected to one end of the connecting shaft, and a second end face gear ring is connected to the second end face gear ring, which is installed inside the protective cover.

[0005] As a preferred technical solution of this application, the driving component includes a motor mounted on the top of the protective cover, the output shaft of the motor is connected to a transmission shaft, and the bottom end of the transmission shaft passes through the protective cover and is connected to the top of the support frame.

[0006] As a preferred technical solution of this application, a bearing is provided at the connection between the outer surface of the rotating shaft and the support frame, a bearing is also provided at the connection between the outer surface of the connecting shaft and the support frame, and a sealed bearing is provided between the outer surface of the transmission shaft and the protective cover.

[0015] In the scheme of this application:

[0016] This application uses a drive component to drive the support frame to rotate. When the support frame rotates, it drives two rotating shafts and the stirring frame to revolve. At the same time, the support frame drives the second end face gear to rotate on the second end face gear ring through the connecting shaft. During this process, the second end face gear and the second end face gear ring cooperate to drive the connecting shaft and the first end face gear ring to rotate. During the rotation of the first end face gear ring, it drives the two first end face gears to rotate. The first end face gears drive the rotating shaft and the stirring frame to rotate. By adopting a stirring method that combines rotation and revolution, compared with the traditional single rotation stirring method, the stirring effect is enhanced, thereby accelerating the volatilization of ammonia and improving the ammonia reduction efficiency.
