Description

Technical Field

[0001] The highly efficient and environment-friendly side suction feeding dust collection device of the utility model relates to the technical field of environmental protection emissions, and particularly relates to a highly efficient and environment-friendly side suction feeding dust collection device. Background Art

[0002] Conventional dust collection methods mostly adopt the design of sucking powder from the top of the dust collection hood, that is, the dust collection hood is placed above the ground feeding port. The middle of the dust collection hood is directly connected to the dust extraction pipeline and the control valve. The dust is directly discharged to the outside through the fan connected to the other end of the dust extraction pipeline. Because it is a top dust collection design, the height of the dust collection hood opening from the ground feeding port is too high, the dust extraction air volume decreases, and the dust scatters and cannot be completely discharged. If it is too low from the ground feeding port, it will affect the operation of material feeding and there is a risk of safety operation. At the same time, the dust adhering to the control valve and the pipeline wall of the vertical pipeline is not easy to clean and is likely to directly fall to the ground feeding port, with the risk of cross-contamination, directly affecting the quality of drugs and causing harm to the human body. In addition, when the control switch of the dust extraction air volume valve of the top discharge type is not tightly closed or the fan is turned off, there is a risk of dust backflow due to the instantaneous negative pressure.

[0003] The dust is directly discharged into the outdoor air after passing through the filter box, and some harmful components in the dust cannot be fully intercepted and purified, polluting the atmospheric environment.

[0004] In view of the problems existing in the above-mentioned prior art, it is very necessary to research and design a new type of highly efficient and environment-friendly side suction feeding dust collection device to overcome the problems existing in the prior art. Summary of the Invention

There is a risk of cross-contamination and affecting the quality of drugs when the bonded dust block falls from the feeding port. There is a risk of instantaneous negative pressure dust backflow in the top discharge type structure. The air simply filtered through the filter box cannot fully intercept and purify the harmful components in the dust, polluting the atmospheric environment and other technical problems. A highly efficient and environment-friendly side suction feeding dust collection device is provided.
