A material conveyor for smelting

Abstract

This utility model discloses a material conveyor for smelting, comprising a sampling tube at the sampling port, a sealing head inside the sampling tube, and a drive rod at the lower end of the sealing head. The lower end of the drive rod passes through the bottom wall of the sampling tube and extends outward, controlling the drive rod to move the sealing head up and down inside the sampling tube. A discharge port is provided on one side of the portion of the sampling tube outside the conveying pipe, and the discharge port is arranged inclined downward from the inside to the outside. This utility model, by setting several sampling tubes on the conveying pipe, with a sealing head, drive rod, and discharge port inside each sampling tube, allows aluminum hydroxide to be discharged along the sampling tube and the discharge port when sampling is required, by controlling the sealing head to move below the discharge port. After sampling, the sealing head moves above the discharge port, stopping the discharge of aluminum hydroxide. This allows for sampling of aluminum hydroxide at any time, and the obtained samples are more random and representative, thereby improving the accuracy of testing.

Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and in particular to a material conveyor for smelting. Background Technology

[0002] After alumina production is completed, it needs to be transported and transferred using a tubular chain conveyor. The tubular chain conveyor is a continuous conveying device for powdery, granular, and lumpy bulk materials. Within a closed pipeline, the conveyor chain acts as a driving component, propelling the material along the pipeline. After alumina preparation, it needs to be sampled and its purity, particle size distribution, crystal structure, and other key indicators precisely tested to ensure the quality of the alumina. Currently, alumina sampling is generally performed using sampling vessels in alumina storage equipment. However, the obtained samples are only alumina on the inner surface of the storage tank, resulting in limited representativeness and making it impossible to sample alumina at any time. This causes significant inconvenience to the sampling process. Utility Model Content

[0014] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0016] like Figure 1-2As shown in the figure, the smelting material conveyor described in this embodiment includes a conveying pipe 1. Several mounting chain links 2 are arranged in the middle of the conveying pipe 1. The mounting chain links 2 are connected by chains 3. Conveying chain plates 4 are arranged on the mounting chain links 2. The conveying chain plates 4 are adapted to the inner diameter of the conveying pipe 1. Several sampling ports are arranged at the lower end of the conveying pipe 1. Bottom-closed sampling pipes 5 are arranged at the sampling ports. The end of the sampling pipe 5 with an opening is connected to the sampling port. A sealing head is arranged at the end of the sampling pipe 5 with an opening. A driving rod 6 is arranged at the lower end of the sealing head. The lower end of the driving rod 6 passes through the bottom wall of the sampling pipe 5 and extends to the outside of the sampling pipe 5. The driving rod 6 is controlled to move the sealing head up and down inside the sampling pipe 5. A discharge port 7 is arranged on one side of the portion of the sampling pipe 5 located outside the conveying pipe 1. The discharge port 7 is arranged inclined downward from the inside to the outside.

[0017] An electric push rod 8 is provided at the bottom of the conveying pipe 1 on the side away from the discharge port 7. The piston rod of the electric push rod 8 is arranged vertically downward, and a linkage plate 9 is provided at the end of the piston rod. The linkage plate 9 is also connected to the end of the drive rod 6 located outside the sampling pipe 5.

[0018] A limiting ring 10 is provided on the part of the drive rod 6 located outside the sampling tube 5. The limiting ring 10 is attached to the bottom wall of the sampling tube 5. The limiting ring 10 restricts the movement of the drive rod 6, thereby preventing the sealing head at the upper end of the drive rod 6 from protruding into the sampling tube 5.

[0019] An inclined guide rail 11 is provided on the sampling tube 5 below the corresponding discharge port 7. The guide rail 11 is arranged inclined downward to guide the falling position of the aluminum hydroxide discharged in the sampling tube 5.

[0020] A sampling box 12 is provided at the lower end of the guide rail 11.

[0021] A placement plate 13 is provided at the lower edge of the sampling tube 5 below the corresponding discharge port 7, and the sampling box 5 is placed on the placement plate 13.

[0022] The sealing head includes a rubber head 14 disposed at the top of the drive rod 6, and a rod head 15 disposed at the upper end of the rubber head 14. The rod head 15 is fixedly connected to the rubber head 14, and the top end of the rod head 15 is adapted to the shape of the inner wall of the conveying pipe 1.

[0023] The working principle of this utility model is as follows: Aluminum hydroxide granules enter the conveying pipe 1. Driven by the drive mechanism, the chain plate 4 moves within the conveying pipe 1, thus propelling the material within the pipe. When sampling of aluminum hydroxide granules within the conveying pipe 1 is required, the piston rod of the electric push rod 8 extends downwards, causing the linkage plate 9 and its drive rod 6 to move downwards together. At this time, the aluminum hydroxide conveyed in the conveying pipe 1 falls into the sampling pipe 5. When the sealing head moves below the discharge port 7, the aluminum hydroxide is discharged along the discharge port 7. The discharged aluminum hydroxide slides down along the guide rail 11. The fallen aluminum hydroxide is collected by the sampling box 12. After the sample is collected, the electric push rod 8 will retract its piston rod. At this time, the sealing head will continue to move upward in the sampling tube 5. When the limiting ring 10 is in contact with the bottom wall of the sampling tube 5, the sealing head will just block the opening at the upper end of the sampling tube 5, thus blocking the entire sampling tube 5. The aluminum hydroxide will then be transported normally in the conveying pipe 1. Finally, the sampling box 12 on the placement plate 13 is removed, and the discharged aluminum hydroxide sample can be sent for testing. The aluminum hydroxide sample can be sampled at multiple locations in the sampling tube 5 on the conveying pipe 1, thereby realizing multi-point random sampling of aluminum hydroxide.

[0024] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
