Precipitation and dust removal device for subway station foundation pit
The invention relates to a precipitation and dust removal device for a subway station foundation pit. Muddy water in the water collecting well outside the outer side wall is filtered into clear water by the pp filter cartridge and then permeates into the inner cartridge, and the water outlet nozzle is in waterway connection with an external dust removal device for the dust removal device to extract the clear water in the inner cartridge of the pp filter cartridge, so that the application of dewatering and dust removal of the foundation pit is realized; when the stepping motor drives the desilting frame to rotate, the surface of the outer side wall of the pp filter cartridge is desilted, and the situation that the outer surface of the pp filter cartridge is too much silt caused by 24-hour dust removal water, the filtering efficiency is reduced, and the dust removal water is interrupted is prevented; the inner cavity of the horn mouth and the inner cylinder of the pp filter cylinder jointly form a clean water tank, the desilting structure, the automatic leakage structure and the pp filter cylinder form a filter device, and when the pressure in the clean water tank is larger than the pressure outside the water outlet of the one-way valve, the one-way valve discharges clean water in the clean water tank, so that the water in the clean water tank is automatically emptied, and transportation is convenient; therefore, recycling of subway station foundation pit rainfall is achieved.
本发明涉及一种用于地铁车站基坑的降水除尘装置；pp过滤筒将外侧壁外集水井内的泥水进行过滤成清水后渗透进内筒内，出水嘴与外部的除尘装置进行水路连接供除尘装置抽取pp过滤筒的内筒内的清水，实现对基坑降水除尘的应用；步进电机驱动清淤框旋转时对pp过滤筒的外侧壁的表面进行清淤，防止24小时除尘用水造成pp过滤筒的外表面淤泥过多而降低了过滤效率，造成除尘用水中断；喇叭口的内腔和pp过滤筒的内筒共同构成清水池，清淤结构和自动泄漏结构以及pp过滤筒构成过滤装置，清水池内的压力大于单向阀的出水口外的压力时单向阀将清水池内的清水排出，实现自动排空清水池内的水，便于运输，从而实现了对地铁车站基坑降水的再利用。
