Description

Filtrate collecting device Technical Field The utility model relates to the technical field of mud-water separation devices, in particular to a filtrate collecting device suitable for a plate-and-frame filter press. Background The plate-and-frame filter press is in filtrate collection and mud discharging function realization, mainly relies on the board that turns over of plate frame below, and when the filtrate was collected, the board was turned over and is in the level state and collect the filtrate, and when mud was discharged, the board was turned over to vertical state, the dropping of filter cake of being convenient for. The turnover plate structure has a plurality of limitations, on one hand, the turnover plate needs a larger space when in turnover, so that enough spare areas are reserved on the periphery of the plate-and-frame filter press, the equipment layout is greatly restricted, and on the other hand, in the unloading process, even if the turnover plate is turned to a vertical state, a filter cake can still fall onto the turnover plate, the fall of the filter cake is blocked, and the mud unloading efficiency is affected. In addition, when the plate-and-frame filter press turns over the mud, go on step by step from the front end to the rear end, and still there is a small amount of filtrate drippings, can't play the effect of collecting the filtrate after the board turns over to vertical state, and the filter cake that drops can drip in the filter cake that drops leads to filter cake secondary pollution. Therefore, there is a need to develop a novel auxiliary device for filtrate collection and sludge discharge to overcome the disadvantages of the conventional flap. Disclosure of utility model The utility model aims to provide a foldable and telescopic filtrate collecting device, which can be used for quickly and reliably unfolding to form a complete liquid guide plate when a plate-and-frame filter press is required to collect filtrate, and can be used for recycling the liquid guide plate through electric operation in a mud discharging stage, so that the whole working efficiency of the filter press is improved, and the requirements of equipment on site space are reduced.
