Description

Technical Field

[0001] The utility model relates to dust-free feeding and discharging equipment for compound additive production, belonging to the technical field of material transportation. Background Art

[0002] The dust-free feeding station is a transfer device that uses negative pressure dust collection. It is suitable for bagging and feeding of transfer materials in the production process. It can store materials first and then transport them. It can be used in conjunction with the dust collection system to effectively prevent dust from flying. The conical part of the silo is equipped with a vibrator to facilitate the flow of materials. A screening system can be installed in the silo to prevent agglomerated materials from blocking the discharge port and conveying pipeline. Designed according to user needs, the material dust and related equipment generated during feeding are effectively isolated from the human body, so that the dust and powder generated during feeding are sucked into the filtration system under the negative pressure condition of the fan, so that the gas and material are separated. When the material accumulates a lot, it falls into the silo due to its own weight. The various existing dust-free feeding structures are complex, the feeding and discharging paths are tortuous, the efficiency is low, and it is easy to get blocked.

[0003] The utility model patent with application number CN202221722627.4 discloses a dust-free feeding device for powdered materials, including a base, a feeding hopper is arranged above the base, a feeding pipe is arranged at the bottom of the feeding hopper, a dust removal device is arranged above the feeding hopper, and the dust removal device includes a load-bearing plate, a discharge port corresponding to the feeding end position of the feeding hopper is arranged in the middle of the load-bearing plate, a dust collecting hood is arranged on the upper surface of the load-bearing plate, a dust collecting pipe is arranged at the upper part of the dust collecting hood, a fan is arranged on the dust collecting pipe, and a dust collecting hood is set up on the upper part of the feeding hopper. When adding materials to the feeding hopper or the feeding hopper vibrates downward to discharge materials, the dust is collected by the dust collecting hood to prevent the dust from being scattered in the production workshop and inhaled by the staff or escaping to the outside world to cause environmental pollution. However, its structure is complicated, and the entire feeding and discharging path is prone to blockage. Utility Model Content
