一、皮带机转接点粉尘解决方案
1. 提出问题
在玉米皮带机输送线上,通常为避免粉尘扩散,采取在输送转接点上加装负压除尘器,存在以下核心问题:
1.1. 粉尘扩散严重,传统斜导料槽出口至受料皮带空间范围内,因物料下落引发的诱导气流及落料冲击等原因,造成粉尘扩散浓度高达80-120 mg/m³。
1.2. 受料皮带频发跑偏,非对称物料冲击力造成皮带单侧受力,年均跑偏10余次,造成皮带磨损加剧,使用寿命缩短30%以上。
1.3. 能耗与维护成本高,传统除尘设备需持续供电(功率≥5.5kW),年耗电量超3万度;滤袋更换、保养等年维护成本>2万元。
2. 解决方案
针对上述问题,拆掉负压除尘设备,换装YCH无动力抑尘导料溜槽。

三、筒仓侧壁放料粉尘解决方案
1. 提出问题
在大豆筒仓侧壁溜管发放作业中,原负压除尘器除尘方案存在以下核心问题:
1.1. 传统除尘系统缺陷,加装除尘器需加固安装平台。
1.2. 性能与成本失衡,除尘后粉尘浓度仍达60-100 mg/m³;
1.3. 电能耗费严重,除尘器功率≥4kW,年耗电>2.5万度;
1.4. 运维效率低下,更换耗材(滤筒等)及人工每年2万元。
2. 解决方案
针对上述问题,拆除原除尘、动力及伸缩溜筒系统,换装微型YCH无动力抑尘料斗,料斗全高度仅为0.4~0.5米。

三、移动皮带机粉尘解决方案
1. 提出问题
某钾肥工厂在移动皮带输送机装车或装集装箱作业中,开放式方案存在以下核心问题:
1.1. 扬尘污染严重:物料下落时因冲击气流产生大量粉尘,作业区域粉尘浓度远超环保标准(如>200 mg/m³),影响工人健康及周边环境。
1.2. 装载效率低下:物料洒落、堆积不均导致需人工干预调整,延长装车时间,降低物流周转率。
1.3. 空间适配性差:传统抑尘设备体积大、重量高,难以匹配移动皮带机的轻量化结构和狭小安装空间。
1.4. 能耗与维护成本高:依赖外部动力(喷淋系统)的抑尘方案能耗大,且需定期维护,增加运营成本。
2. 解决方案
针对上述问题,设计YGH无动力抑尘料斗+导流罩集成系统。
3. 实施效果
