Description

Technical Field

[0001] This utility model relates to the field of closed transport technology for ball materials, and specifically to a chute-type feeding device for closed transport of ball materials. Background Technology

[0002] In certain pyrometallurgical processes, the reaction needs to be carried out under specific atmospheric conditions. Therefore, the airtightness of the equipment becomes a key factor affecting whether the reaction can achieve the expected results. In addition, in order to more effectively promote the contact between various materials and facilitate the effective reaction, the industry generally adopts a method of preparing various powdered materials into spherical materials of a specific diameter by using a disc granulator in a "snowballing" manner.

[0003] Ball material feeding methods mainly include screw conveying, conveyor belt conveying, and pipeline conveying. Among them, conveyor belt feeding has poor sealing performance and a high failure rate; while screw feeding is prone to causing the ball material to break into powder after being squeezed, especially for sticky materials, which can easily cause the feeding rotating structure to jam.

[0004] Pipeline conveying has become a preferred feeding method due to its simple structure, ease of maintenance, and excellent sealing performance. However, pipeline conveying is limited by the installation environment. When the pipeline is installed at a small angle, spherical materials cannot smoothly enter the next process by their own weight. In addition, some spherical materials containing water may break or pulverize during the conveying process, leading to adhesion on the inner wall of the pipeline, causing material accumulation and blockage. Summary of the Invention

[0005] In response to the problems raised in the background art, this utility model provides a chute-type feeding device for closed transportation of ball materials to solve the problems. The utility model will be further described below.

[0006] A chute-type feeding device for closed transport of ball materials includes an inclined feeding pipe, the feeding end of which is connected to the discharge end of the previous process, a pipe vibrator installed at the bottom of the feeding pipe, and a purge pipe provided at the upper end of the feeding pipe. The purge pipe is inclined and communicates with the feeding pipe, and the other end of the purge pipe is connected to a pneumatic regulating valve, which is connected to an external air pipe.

[0007] Preferably, the feed end of the feed pipe is connected to the discharge end of the previous process via a flange;

[0015] Preferably, one of the purge pipes is at a clockwise angle to the feed pipe, and the other purge pipe connected to the bend is at a counterclockwise angle to the feed pipe.

[0016] Beneficial effects: Compared with the prior art, this utility model utilizes the operation of the pipeline vibrator to effectively promote the complete discharge of all residual ball material from the inclined tube; if the material is broken or pulverized during collision, generating water-containing viscous powder that remains in the pipeline, the gas purging procedure specified in the process can ensure that no dust accumulates in the pipeline, thereby reducing the resistance during the ball material transportation process; under the above two measures, the smooth transportation of ball material is guaranteed, and the closed transportation of ball material is realized throughout the entire feeding and discharging process.
